  • The Potential Mechanism of Zishen Yutai Pills against Threatened Abortion:
           An Approach Involving Network Pharmacology and Experimental Evidence

    • Abstract: Threatened abortion (TA) is the most common complication in early pregnancy and is caused by anxiety and depressive symptoms. The Zishen Yutai Pill (ZYP) is a traditional herbal formula that is commonly used to treat TA. However, the pharmacological mechanisms underlying the effect of ZYP have yet to be elucidated. To disclose the mechanism of ZYP in the treatment of TA, first, we identified the chemical constituents of ZYP from multiple databases and then predicted the potential targets of TA by applying the GeneCards database. A protein-protein interaction (PPI) network was then constructed to allow the screening of hub targets. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGGs) enrichment analyses were also performed and the Database for Annotation Visualization and Integrated Discovery server was used to identify critical biological processes and signaling pathways. Cytoscape software was used to construct a Compound-Target-Pathway. Furthermore, we analyzed ZYP by UPLC-Q-TOF/MS, then the RU486-induced TA rat model was established, and the reliability of the network pharmacology prediction results was verified. Finally, the mechanisms responsible for the action of ZYP on TA were revealed by qRT-PCR and molecular docking. Database screening identified a total of 161 active compounds in ZYP and 324 TA-related targets. And, we identified 42 compounds from ZYP by UPLC-Q-TOF/MS. Inflammation and apoptosis were identified as the main biological processes. GO and KEGG analyses identified that the MAPK and PI3K/Akt pathways were the key functional pathways that respond to ZYP. The results showed that ZYP treatment significantly increased maternal weight, significantly increased the levels of estradiol and progesterone, and attenuated histopathological changes in a rat model of TA. Data indicated that ZYP treatment improved pregnancy outcomes in the rat model of TA. QRT-PCR data showed that ZYP reduced inflammation and apoptosis by regulating the MAPK and PI3K/Akt pathways. In addition, molecule docking results identified a range of key compounds, including Pik3a, Mapk14, Mapk1, Mapk3, Mapk8 Tnf, Il6, and Cas8. In summary, we performed network pharmacological analysis and experimental validation and identified that ZYP exerts an effect on TA by regulating the MAPK and PI3K/Akt pathways and by inhibiting the expression levels of proinflammatory cytokines and genes related to apoptosis.

  • QiHuangYiShen Granules Modulate the Expression of LncRNA MALAT1 and
           Attenuate Epithelial-Mesenchymal Transition in Kidney of Diabetic
           Nephropathy Rats

    • Abstract: Background. QiHuangYiShen granules (QHYS), a traditional Chinese herbal medicine formula, have been used in clinical practice for treating diabetic kidney disease for several years by our team. The efficacy of reducing proteinuria and delaying the decline of renal function of QHYS has been proved by our previous studies. However, the exact mechanism by which QHYS exerts its renoprotection remains largely unknown. Emerging evidence suggests that lncRNA MALAT1 is abnormally expressed in diabetic nephropathy (DN) and can attenuate renal fibrosis by modulating podocyte epithelial-mesenchymal transition (EMT). Objective. In the present study, we aimed to explore whether QHYS could modulate lncRNA MALAT1 expression and attenuate the podocyte EMT as well as the potential mechanism related to the Wnt/β-catenin signal pathway. Methods. SD rats were fed with the high-fat-high-sucrose diet for 8 weeks and thereafter administered with 30 mg/kg streptozotocin intraperitoneally to replicate the DN model. Quality control of QHYS was performed using high-performance liquid chromatography. QHYS were orally administered at 1.25, 2.5, and 5 g/kg doses, respectively, to the DN model rats for 12 weeks. Body weight, glycated haemoglobin, blood urea nitrogen, serum creatinine, 24-h proteinuria, and kidney index were measured. The morphologic pathology of the kidney was evaluated by Hematoxylin-eosin and Masson’s trichrome staining. The expression level of lncRNA MALAT1 was determined by quantitative real-time polymerase chain reaction. In addition, the expression levels of podocyte EMT protein markers and Wnt/β-catenin pathway proteins in renal tissues were evaluated by Western blotting and immunohistochemistry. Results. The results showed that QHYS significantly reduced 24-h proteinuria, blood urea nitrogen, kidney index, and ameliorated glomerular hypertrophy and collagen fiber deposition in the kidney of DN rats. Importantly, QHYS significantly downregulated the expression level of lncRNA MALAT1, upregulated the expression of nephrin, the podocyte marker protein, downregulated the expression of desmin and FSP-1, and mesenchymal cell markers. Furthermore, QHYS significantly downregulated the expression levels of Wnt1, β-catenin, and active β-catenin. Conclusion. Conclusively, our study revealed that QHYS significantly reduced proteinuria, alleviated renal fibrosis, and attenuated the podocyte EMT in DN rats, which may be associated with the downregulation of lncRNA MALAT1 expression and inhibition of the Wnt/β-catenin pathway.

  • Effects of Intensive Glycemic Control on Serum Exosome miR-126-3p and
           miR-125b-1-3p Levels and Wound Healing in Patients with Diabetic Ulcers

    • Abstract: Objective. Intensive glycemic control and exosomal miRNAs have both been reported to improve wound repair in diabetic ulcers. In this study, we aimed to investigate the effects of intensive glycemic control on serum exosome microRNA-126-3p (miR-126-3p), microRNA-125b-1-3p (miR-125b-1-3p), and wound healing in patients with diabetic ulcers. Methods. Herein, 45 diabetic patients with an ulcer, aged 35–75 years old, were randomly assigned to the intensive glycemic control group (n = 21) and the conventional glycemic control group (n = 24). Serum exosomes were extracted in the laboratory and assessed by Western blotting, transmission electron microscopy, and nanoparticle tracking analysis. The expression of miR-126-3p and miR-125b-1-3p was validated using quantitative real-time polymerase chain reaction. The wound healing of each diabetic ulcer patient was measured and imaged; additionally, clinical and follow-up data were collected. Finally, the clinical and laboratory data were combined for statistical analysis. Results. Intensive glycemic control was significantly more conducive to wound healing and infection control than conventional glycemic control . Serum exosomal miR-126-3p was negatively correlated with fasting plasma glucose levels (r = 0.34, ) and positively associated with the wound healing rate (r = 0.45, ). The level of miR-126-3p in the intensive glycemic control group was significantly higher than that in the conventional glycemic control group . Serum exosomal miR-125b-1-3p was not correlated with blood glucose levels (r = 0.03, ) and was positively associated with the wound healing rate (r = 0.33, ). No significant difference was observed in the level of miR-125b-1-3p between the intensive and conventional glycemic control groups. Regarding the prognosis of diabetic ulcers, the intensive glycemic control group was better than the conventional group (Z = −2.02, ).Conclusion. Serum exosome (miR-125b-1-3p and miR-126-3p) levels are correlated with wound healing in diabetic ulcers. Intensive glycemic control increases the serum exosomal miR-126-3p level, which might be one of the mechanisms that promotes wound healing in diabetic ulcers.

  • Clinical Evidence and Potential Mechanisms in Treating Radiation Enteritis
           with Modified Baitouweng Decoction

    • Abstract: Objectives. To perform a meta-analysis and network analysis identification to evaluate the efficacy, safety, and potential mechanisms of modified Baitouweng decoction (mBTWD) in the treatment of radiation enteritis. Methods. We searched PubMed, Embase, Cochrane Library, Web of Science, CNKI, Wanfang Databases, SionMed, and Chinese Scientific Journals Database to collect the randomized controlled trials (RCTs) of mBTWD treating radiation enteritis. Rev.Man 5.3 and Stata 14.0 software are employed for meta-analysis. The GRADE online tool is used to evaluate the quality of evidence. Network analysis and molecular docking approach are applied to predict the potential targets and ingredients of representative drugs in mBTWD for the treatment of radiation enteritis. Results. Seventeen studies are eventually included, covering a total of 1611 patients: (1) The clinical efficacy is significantly higher in mBTWD groups than in control groups (RR = 1.24, 95% CI (1.17, 1.32), ). (2) mBTWD has certain advantages in improving TCM syndromes (MD = −3.41, ). (3) mBTWD has a certain positive effect on the improvement of intestinal signs and symptoms (RR = 1.23, ; OR = 3.51, ). (4) Indexes including CRP, KPS, and OB, are better in mBTWD groups than in control groups (,,), but the credibility is downgraded for a small sample size. Adverse events and recurrence rates require further confirmation with larger sample sizes. (5) Univariate meta-regression for clinical efficacy shows none of the coefficients are significantly associated with the estimated risk ratio. The clinical efficacy overestimates about 4.9% from publication bias. The quality of the included studies is low according to GRADE evidence. (6) Quercetin, isorhamnetin, and beta-sitosterol are the main ingredients from representative drugs in mBTWD and its key targets are MYC, TP53, and MAPK14/MAPK1. Conclusions. mBTWD may be effective in the treatment of radiation enteritis, but its long-term benefits, safety, and molecular mechanisms remain unclear due to the poor quality of the evidence. Larger sample sizes, high-quality studies, and basic research are essential in the future.

  • Efficacy of Kami Guibi-tang as an Add-On Therapy to Acetylcholinesterase
           Inhibitor for Cognitive Function in Mild Alzheimer’s Disease: A Pilot

    • Abstract: Background. Kami Guibi-tang (KGT), a traditional Korean herbal medicine is mainly used to treat insomnia and nervousness. Acetylcholinesterase inhibitors (AChEIs) are the main treatments for mild Alzheimer’s disease (AD), a degenerative brain disease. However, currently no drug can fundamentally treat AD or reverse the advanced cognitive decline. This clinical study explored the efficacy and safety of adding KGT to AChEI for cognitive function in mild AD. Methods. This was a pilot study for a larger randomized, double-blind, placebo-controlled trial. Participants between 55–90 years diagnosed with mild AD were recruited from Kyung Hee University Hospital at Gangdong, Seoul, Korea. They were randomized to receive either KGT or placebo for 24 weeks, in addition to their regular AChEI. The primary outcome was treatment efficacy, as assessed by the relative amount of change over the study period in total scores on the Dementia version of the Seoul Neuropsychological Screening Battery (SNSB-D). Changes in SNSB subscores were assessed as secondary outcomes. Safety parameters, including adverse events and abnormalities in blood tests, electrocardiograms, and brain magnetic resonance imaging were also monitored. Results. Between March 2018 and November 2020, seven participants each in the KGT group and the placebo group completed the 24-week trial. There were no significant changes in SNSB-D total or subindex scores for either group ( = 0.69 and 0.63, respectively), and no significant differences were observed between them (). No adverse events related to KGT were reported. We also compared and analyzed the results of a previous pilot study conducted on amnestic mild cognitive impairment (aMCI) using protocol of this study. The aMCI group showed a significant improvement in the total SNSB-D score, especially in the memory domain, compared to the mild AD group ( = 0.04 and 0.02, respectively). The Korean Mini-Mental State Exam and Korean Instrumental Activities of Daily Living scores also significantly improved in the aMCI group ( = 0.01 and 0.02, respectively). Conclusions. Compared to placebo, adding KGT to AChEI did not significantly improve cognitive function in SNSB in patients with mild AD. We suggest that KGT would have a positive effect on patients with early stages of cognitive impairment such as aMCI. The findings could assist design larger, longer-term clinical trials of KGT use in elderly patients with mild AD. This study was registered in the Korean Clinical Trial Registry on December 26, 2017, with the CRIS approval number KCT0002904.

  • The Immunoregulatory Effect of Aconite Treatment on H22 Tumor-Bearing Mice
           via Modulating Adaptive Immunity and Natural Killer-Related Immunity

    • Abstract: Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer and, in its advanced stages, has a 5-year survival rate of only 3% to 5%. Despite novel mechanisms and treatments being uncovered over the past few years, effective strategies for HCC are currently limited. Previous studies have proven that aconite can suppress tumor growth and progression and prevent the recurrence and metastasis of multiple cancers, but the underlying molecular mechanisms are largely unknown. In this study, different doses of aconite were applied to mice bearing subcutaneous HCC tumors. It was found that aconite had a therapeutic effect on H22 tumor-bearing mice in a dose-dependent manner by reducing tumor volumes and prolonging survival times, which could be attributed to the immunoregulatory effect of aconite. Furthermore, results showed that high-dose administration of aconite could enhance adaptive immunity and natural killer (NK) cell-mediated immunity by regulating the secretion of interferon-γ, upregulating T cells and NK cells, and modulating the expression of the NK cytotoxicity biomarker CD107a and the inhibitory receptor TIGIT. This study revealed a novel mechanism through which aconite exerts antitumor effects, not merely through apoptosis induction pathways, providing more sound evidence that aconite has the potential to be developed into an effective anti-HCC agent.

  • To Investigate the Clinical Efficacy and Potential Mechanism of Tongxinluo
           Capsules in Preventing Coronary Restenosis Based on Meta-Analysis and
           Network Pharmacology Analysis

    • Abstract: Objective. The aim of this study is to evaluate the clinical efficacy of Tongxinluo capsules in preventing coronary restenosis based on meta-analysis and network pharmacology research methods and to preliminarily explore its intervention mechanism. Methods. First, through meta-analysis, we comprehensively searched databases such as CNKI, Wanfang, PubMed, the Cochrane Library, and Web of Science to find out the randomized controlled trials of Tongxinluo capsules in the treatment of coronary restenosis until February, 2022. According to the Cochrane Library, risk bias assessment tools were used to evaluate the included literature and Review Manager 5.2 software was used to conduct statistical analysis of the included studies. Then, based on network pharmacology, through TCMSP database and BATMAN-TCM database screening, the chemical components of Tongxinluo capsules and their related effects, symptom, and common targets were analyzed. String net was used to construct protein-protein interaction (PPI) network, and R3.6.1 software was used to carry out GO biological process enrichment analysis and KEGG signaling pathway enrichment analysis to clarify key pathways. Results. The meta-analysis finally included 10 RCTs with a total of 1318 subjects. Meta-analysis results showed that Tongxinluo capsules combined with conventional cardiovascular drugs could significantly improve the clinical efficacy of preventing in-stent restenosis and the clinical efficacy of preventing angina pectoris. There was no significant difference in the clinical efficacy of preventing myocardial infarction. Network pharmacology obtained a total of 101 chemical components and 149 targets through the online database. The results of network analysis showed that the targets were mainly involved in receptor ligand activity, carboxylic acid binding, steroid hormone receptor activity, and other related action pathways and were also involved in AGE-RAGE signaling pathway, cell senescence signaling pathway, and other related pathways. Conclusion. Tongxinluo capsules combined with conventional cardiovascular drugs can improve the clinical efficacy of preventing in-stent restenosis and angina pectoris and have a significant effect on reducing inflammatory factors. The comprehensive result of the effect is mainly through the participation of receptor ligand activity, carboxylic acid binding, steroid hormone receptor activity, and other ways to achieve the purpose of treating coronary restenosis.

  • Shuangdan Mingmu Capsule for Diabetic Retinopathy: A Systematic Review and
           Meta-Analysis of Randomized Controlled Trials

    • Abstract: Objective. To systematically evaluate the efficacy and safety of the Shuangdan Mingmu capsule in the treatment of diabetic retinopathy (DR). Methods. Common Chinese and English databases, including PubMed, Medline, Embase, VIP, Wanfang, and the Chinese National Knowledge Infrastructure (CNKI), were searched from their inception to May 31, 2022. According to the Cochrane Handbook, two reviewers independently evaluated and collected data on the included studies. Meta-analysis was performed by RevMan software 5.4. Results. Seven trials with a total of 835 patients were included. The clinical effectiveness rate was defined as the primary outcome, and the TCM symptom score, Chinese-Version Low Vision Quality of Life Questionnaire (CLVQOL) scores, macular thickness, hemorrhagic spot area, vascular endothelial growth factor levels, platelet-derived growth factor levels, and the incidence of adverse effects were the secondary outcome. The results of the meta-analysis showed that, compared with conventional medical treatment alone, the Shuangdan Mingmu capsule combined with conventional treatment could significantly improve the clinical effectiveness rate of treating DR (OR = 4.07, 95% CI (2.10, 7.89), ), and reduce the incidence of adverse reactions in DR patients (OR = 0.47, 95% CI (0.26, 0.86), ). In addition, other results showed that TCM symptom score(OR = −3.47, 95% CI (−3.84, −3.10), ); CLVQOL scores (OR = 23.93, 95% CI (21.37, 26.49), ); macular thickness (OR = −47.34, 95% CI (−50.67, 44.00), ); hemorrhagic spot area (OR = −0.91, 95% CI (−1.01, −0.81), ); vascular endothelial growth factor levels (OR = −45.76, 95% CI (−49.74, 41.79), ); platelet-derived growth factor levels (OR = −1.73, 95% CI (−2.15, −1.31), ).Conclusion. Compared with conventional treatment alone, the Shuangdan Mingmu capsule combined with conventional treatment is more effective and safer in the treatment of diabetic retinopathy. However, due to the limitations of the included studies, more high-quality studies are still needed to further assess the efficacy and safety of the Shuangdan Mingmu capsule in the treatment of diabetic retinopathy.

  • Systematically Investigating the Pharmacological Mechanism of Momordica
           grosvenori in the Treatment of Spinal Cord Injury by Network Pharmacology
           and Experimental Verification

    • Abstract: Objective. This study aimed to explore the molecular mechanism of Momordica grosvenori (MG) in spinal cord injury (SCI) by network pharmacology analysis. Methods. We searched for potential active MG compounds using the TCMSP database and the BATMAN-TCM platform. The Swiss target prediction database was used to find MG-related targets and the targets of SCI from the CTD, GeneCards, and DrugBank databases. Following that, a protein-protein interaction (PPI) study was carried out. Cytoscape software was used to calculate the hub gene, and R software was used to evaluate the Gene Ontology (GO) and KEGG enrichment pathways. Finally, molecular docking between the hub protein and important compounds was performed. We verified STAT3, MAPK1, HSP90AA1, PIK3R1, PIK3CA, and RXRA potential targets by quantitative PCR. Results. We obtained 293 MG-anti-SCI targets with potential therapeutic utility by intersecting 346 MG-related targets and 7214 SCI-related targets. The top 10 identified genes, ranking in descending order of value, were SRC, STAT3, MAPK1, HSP90AA1, PIK3R1, PIK3CA, RXRA, AKT1, CREBBP, and JAK2. Through enrichment analysis and literature search, 10 signaling pathways were screened out. The molecular docking of important drugs and hub targets revealed that some had a higher binding affinity. The results of quantitative PCR indicated that MAPK1, RXRA, and STAT3 were expressed differently in in vitro experiments. Conclusion. In conclusion, the current work indicated that MG might play an anti-SCI role via multicomponent, multitarget, and multichannel interaction, which presents a novel idea for further research into the precise mechanism of MG-anti-SCI interaction.

  • Prevention of Bleomycin-Induced Pulmonary Inflammation and Fibrosis in
           Mice by Bilobalide

    • Abstract: Idiopathic pulmonary fibrosis (IPF) is a fatal interstitial lung disease. Bilobalide (BB) is a sesquiterpene isolated from Ginkgo biloba, and its role in IPF is poorly understood. Mice were intratracheally instilled with 2.5 mg/kg bleomycin (BLM) to induce IPF and then treated with 2.5, 5, and 10 mg/kg BB daily for 21 days. Treatment with BB ameliorated pathological injury and fibrosis of lung tissues in BLM-induced mice. BB suppressed BLM-induced inflammatory response in mice as demonstrated by reduced inflammatory cells counts (leukocytes, neutrophils, macrophages, and lymphocytes) and pro-inflammatory factors (CCL2 and TNF-α), as well as increased CXCL10 levels in BALF. The expression of BLM-induced hydroxyproline, LDH, and pro-fibrotic mediators including fibronectin, collagen I, α-smooth muscle actin (α-SMA), transforming growth factor (TGF)-β1, matrix metalloproteinase (MMP)-2, and MMP-9 in lung tissue was inhibited by BB treatment, and the tissue inhibitor of metalloproteinase-1 (TIMP-1) expression was increased. BB blocked the phosphorylation of JNK and NF-κB, and the nuclear translocation of NF-κB in the lung tissue of mice induced by BLM. Additionally, it abated the activation of NLRP3 inflammasome in lung tissue induced by BLM, which led to the downregulation of IL-18 and IL-1β in BALF. Our present study suggested that BB might ameliorate BLM-induced pulmonary fibrosis by inhibiting the early inflammatory response, which is probably via the inhibition of the JNK/NF-κB/NLRP3 signal pathway. Thus, BB might serve as a therapeutic potential agent for pulmonary inflammation and fibrosis.

  • Reporting Quality of Oral TCM Systematic Reviews Based on the PRISMA Harms
           Checklist from 2013 to 2020

    • Abstract: Background. Systematic reviews focusing on the effectiveness of different kinds of healthcare interventions have been widely published, but there were few guidelines for reporting safety concerns before 2016. The PRISMA harms checklist, which was published in 2016, can standardize reporting quality. Objectives. To evaluate the safety information reporting quality of oral traditional Chinese medicine (TCM) in systematic reviews before and after the PRISMA harms checklist was published and to explore factors associated with better reporting. Methods. We searched PubMed, the Cochrane Library, and Embase to identify all systematic reviews using oral TCM as interventions published before (from 2013 to 2015) and after (from 2017 to 2020) the PRISMA harms checklist was published. We used the PRISMA harms checklist to assess the quality of reporting of the safety information to included systematic reviews. Results. In total, 200 systematic reviews were sampled from eligible studies published between 2013 and 2020. Reviews from 2016 were excluded. Scores on the PRISMA harms checklist (23 items) ranged from 0 to 12. A systematic reviews published after 2016 had better reporting quality compared with studies published before 2016 with regard to the title (), results of individual studies (), and risk of bias across studies (). In all included systematic reviews of our study, the state conclusion in coherence with review findings was reported adequately with the proportion of adherence at 95%; other items had a reporting proportion ranging from 0% to 57%. The four essential reporting items of the PRISMA harms checklist also had a low reporting quality ranging from 0% to 4%. Conclusions. Oral TCM systematic reviews reported inadequate safety information before and after the PRISMA harms checklist was published. This survey suggested that the PRISMA harms checklist should be recommended more to both original research and systematic review authors.

  • The Effective Components, Core Targets, and Key Pathways of Ginseng
           against Alzheimer’s Disease

    • Abstract: Background. Panax ginseng C. A. Mey (ginseng) is a traditional Chinese medicinal herb used for the treatment of nervous system disorders, such as Alzheimer’s disease (AD). However, the pharmacological mechanisms of ginseng involved in AD have not been systematically investigated. Here, a network pharmacology approach was adopted to explore the effective components, core targets, and key pathways of ginseng against AD. Methods. TCMSP database was used to screen the active ingredients of ginseng. Prediction of the targets of ginseng and AD-related genes was performed using online public databases. “Compound-Target,” “Compound-Target-Disease,” “Protein-Protein Interaction (PPI),” “Compound-Target-Pathway,” and “Compound-Target-GO–Pathway” networks were constructed with Cytoscape 3.7.2 software. Gene Ontology (GO) function annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment were performed by using the DAVID database. Results. A total of 22 bioactive compounds were identified from ginseng, and 481 targets of ginseng and 763 AD-related targets were obtained from public databases. The PPI network screened out 19 hub genes of ginseng against AD. According to GO function enrichment, ginseng influenced cell proliferation, death, the nitric oxide biosynthetic process, hypoxia response, and synaptic transmission. Neuroactive ligand-receptor interaction, serotonergic synapse, calcium signaling, cAMP signaling, FoxO signaling, Ras signaling, and PI3K-AKT signaling were among the most key regulatory pathways. The compound-target-GO-route network found EGFR, MAPK1, MAPK14, AKT1, CASP3, and PRKACA as key genes, with PI3K-AKT signaling being the most important pathway for ginseng’s anti-AD activity. Conclusion. Ginseng exerts neuroprotective effects in AD patients through multicomponent, multitarget, and multipathway modes, providing novel insight into the pharmacological and experimental research on ginseng against AD.

  • Polyphyllin I Effects Candida albicans via Inhibition of Virulence Factors

    • Abstract: Paris polyphylla is often used in Chinese medicine to treat conditions such as carbuncles, trauma, snake bites, and mosquito bites. In the present study, we investigated the effect and mechanism of the morphological transition and extracellular phospholipase activity of Candida albicans treated with polyphyllin I (PPI). First, the minimum inhibitory concentration and antifungal activity of PPI were evaluated using the multiple microdilution method and time-killing assays. Then, the effect of PPI on the morphological transition of Candida albicans in Spider liquid medium and Sabouraud-dextrose liquid medium containing 10% fetal bovine serum was observed under an inverted microscope and by scanning electron microscopy. Finally, egg yolk agar plates were used to evaluate extracellular phospholipase activity. Gene expression was detected by real-time quantitative polymerase chain reaction analysis. Our results suggest that PPI inhibited the transition from the yeast to the hyphal stage and decreased secreted aspartyl proteinase activity. We further confirmed that PPI significantly downregulated the expression of extracellular phospholipase genes and cAMP-PKA signaling pathway-related genes. Taken together, our results suggest that PPI exerts anti-Candida albicans activity by inhibiting virulence characteristics, including the yeast-to-hyphal transition and the secretion of aspartyl proteases and phospholipases. The study results also indicated that PPI could be a promising therapeutic strategy for Candida albicans.

  • Effect and Mechanism of Dragon’s Blood on Wound Healing of Patients
           with Stress Hand Injury

    • Abstract: This study aimed to explore the effect and mechanism of Dragon’s Blood on wound healing in patients with a pressure hand injury. A total of 120 patients with pressure hand injury treated in our hospital were randomly divided into two groups. Sixty patients in the control group were dressed with sterile gauze, and 60 patients in the observation group were smeared with blood exhaustion. The clinical effects and serological indexes of the two groups were compared, and the mechanism of wound healing was analyzed. The results showed that the treatment effective rate of the control group was 80% and that of the observation group was 93.33%. The treatment effective rate of the observation group was dramatically higher (). The number of patients with good granulation tissue in the observation group was 53, which was dramatically greater than that in the control group. The number of patients with a small amount of wound exudation was 51, which was dramatically greater than that in the control group (). After treatment, the levels of matrix metalloproteinase (MMP-3), vascular endothelial growth factor (VEGF), and transforming growth factor B1 (TGF-B1) in the observation group increased more dramatically (). The level of tissue inhibitor of metalloproteinase-1 (TIMP-1) decreased to 617.23 ng/L in the observation group, and the degree of reduction was more obvious (). Notably, Dragon’s Blood promoted wound healing at the injury site by increasing the levels of MMP-3, VEGF, and TGF-B1and decreasing TIMP-1. The area of wound reduction in the observation group was 0.27 cm2, and the reduction was more obvious (). The healing time of pressure hand injury in the observation group was 15.27 days, which was dramatically shorter (). In summary, Dragon’s Blood had a good effect on the healing of the injured site in patients with pressure hand injury, which is worthy of promotion.

  • Inhibitory Effect of Astragalus Polysaccharide on Premetastatic Niche of
           Lung Cancer through the S1PR1-STAT3 Signaling Pathway

    • Abstract: As a common malignant tumor, the morbidity and mortality of lung cancer have been rising in recent years. The concept of “premetastatic niche” may lead to a revolutionary change in antitumor metastasis therapeutic strategies. Traditional Chinese medicine with multitargets and lower poisonous agents may be a potentially effective means to intervene in the “premetastatic niche (PMN)” to prevent and treat tumor metastasis. Astragalus polysaccharide (APS) is a substance with strong immune activity in Astragalus membranaceus that has excellent biological activities such as immunomodulation, anti-inflammatory, and antitumor. In this study, we constructed a tumor lung metastasis animal model to explore the intervention mechanism of APS on the premetastatic niche. We found that APS inhibited the formation of the lung premetastatic niche and inhibited the recruitment of myeloid-derived suppressor cells (MDSCs) in the lung. Mechanistically, we showed that the proteins and gene expression of S1PR1, STAT3, and p-STAT3 in the S1PR1/STAT3 signaling pathway were suppressed by APS. In line with the above findings, our results confirmed that APS may inhibit the accumulation of MDSCs in the premetastatic niche through the intervention of the S1PR1-STAT3 signaling pathway to achieve the antitumor effect.

  • Fisetin Ameliorates Diabetic Nephropathy-Induced Podocyte Injury by
           Modulating Nrf2/HO-1/GPX4 Signaling Pathway

    • Abstract: Diabetic nephropathy (DN) is one of the most severe microvascular complications of diabetes and has become the leading cause of end-stage renal disease formation. The pathogenesis of diabetic nephropathy is very complex and is still not fully understood. Fisetin is a flavonoid polyphenolic compound that is widely found in different fruits, vegetables, and medicinal plants. Many studies have indicated that it has a variety of pharmacological activities. In this study, we investigated the mechanism of action of fisetin in the protection of DN-induced podocyte injury both in vivo and in vitro. Results showed that fisetin could reduce high glucose (HG)-induced podocyte injury and streptozotocin (STZ)-induced diabetic nephropathy in mice. According to the histopathological staining results, fisetin ameliorated DN-induced glomerular injury in a dose-dependent manner. Western blot and immunofluorescence results showed that fisetin effectively promoted the expression of podocyte functional integrity marker proteins and inhibited the expression of podocyte injury marker proteins. In addition, according to the Western blot and RT-qPCR results, fisetin activates the nuclear translocation of Nrf2 to exert antioxidative stress ability and affects the expression of downstream antioxidant enzymes HO-1, GPX4, and other ferroptosis-related markers, thereby protecting against HG-induced podocyte ferroptosis and oxidative stress injury in DN mice. In summary, this study demonstrated that fisetin could enhance the antioxidative stress capacity of DN mice by promoting the activation of the Nrf2/HO-1/GPX4 signaling pathway in renal tissues, and attenuated HG-induced podocytes injury and STZ-induced DN in mice.

  • Evaluation of Wound Healing and Anti-Inflammatory Activities of 80%
           Methanol Crude Extract and Solvent Fractions of Trichilia dregeana Sond
           (Meliaceae) Leaves in Mice

    • Abstract: Introduction. The leaves of Trichilia dregeana Sond are traditionally used to treat wounds. Even though there have been in vitro studies and claims supporting wound healing, there are no scientific data on in vivo wound healing and anti-inflammatory activities of the leaves of T. dregeana. Objective. This study aimed to evaluate wound healing and anti-inflammatory activity of 80% methanol crude extract and solvent fractions of T. dregeana in mice. Method. The leaves of T. dregeana were dried, ground, and macerated with 80% methanol three times successively. The crude extract was fractioned by water, ethyl acetate, and hexane separately. The acute dermal and oral toxicity tests were done by applying 2000 mg/kg of 10% (w/w) crude extract ointment (CEO) topically and 2000 mg/kg of crude extract orally, respectively. The wound healing activity of the crude extract was evaluated on excision, incision, and burn wound models while the fractions were evaluated only on excision wound model. The anti-inflammatory activity of the crude extract was evaluated on xylene-induced ear edema and cotton pellet granuloma tests. Result. Both acute dermal and oral toxicity tests were found to be safe after topical application of 2000 mg/kg of 10% (w/w) CEO and oral administration of 2000 mg/kg of crude extract suspension, respectively. Both 5% and 10% (w/w) CEO produced significant (

  • Integrated Network Pharmacology and Proteomic Analyses of Targets and
           Mechanisms of Jianpi Tianjing Decoction in Treating Vascular Dementia

    • Abstract: Background. Vascular dementia (VD), associated with cerebrovascular injury, is characterized by severe cognitive impairment. Jianpi Tianjing Decoction (JTD) has been widely used to treat VD. However, its molecular targets and mechanisms of action in this treatment remain unclear. This study integrated network pharmacology and proteomics to identify targets and mechanisms of JTD in the treatment of VD and to provide new insights and goals for clinical treatments. Methods. Systematic network pharmacology was used to identify active chemical compositions, potential targets, and mechanisms of JTD in VD treatment. Then, a mouse model of VD was induced via transient bilateral common carotid artery occlusion to verify the identified targets and mechanisms of JTD against VD using 4D label-free quantitative proteomics. Results. By screening active chemical compositions and potential targets in relevant databases, 187 active chemical compositions and 416 disease-related compound targets were identified. In vivo experiments showed that JTD improved learning and memory in mice. Proteomics also identified 112 differentially expressed proteins in the model and sham groups and the JTD and model groups. Integrating the network pharmacology and proteomics results revealed that JTD may regulate expressions of cytochrome c oxidase subunit 7C, metabotropic glutamate receptor 2, Slc30a1 zinc transporter 1, and apolipoprotein A-IV in VD mice and that their mechanisms involve biological processes like oxidative phosphorylation, regulation of neuron death, glutamate secretion, cellular ion homeostasis, and lipoprotein metabolism. Conclusions. JTD may suppress VD development via multiple components, targets, and pathways. It may thus serve as a complementary treatment option for patients with VD.

  • The Effect of Traditional Chinese Medicine on Postviral Olfactory
           Dysfunction: A Systematic Review and Meta-Analysis

    • Abstract: Objective. The aim of this study is to evaluate the efficacy and safety of traditional Chinese medicine (TCM) for postviral olfactory dysfunction (PVOD). Methods. PubMed, EMBASE, Cochrane Central Register of Controlled Trials, China Network Knowledge Infrastructure (CNKI), Chinese Scientific Journal Database (VIP), Chinese Biomedical and Medical (CBM) Database, and Wanfang Database were electronically searched from their inception to July 25, 2022. Two authors independently performed study selection, data extraction, and quality assessment to ensure systematic quality evaluation. Randomized controlled trials (RCTs) comparing TCM with olfactory training and/or drug therapy (OTDT) were included. The outcomes were the effective rate, QOD-P, TDI score, UPSIT score, and adverse effects. Cochrane RoB was the guideline used to evaluate the methodological quality of the included trials. RevMan 5.3 software was used for statistical analysis. Results. A total of 6 RCTs involving 467 patients with PVOD were selected. Compared with OTDT, TCM plus OTDT decreased QOD-P (MD = −1.73, 95% CI (−2.40, −1.06), ) but did not increase the effective rate (T&T) (RR = 1.28, 95% CI (0.86, 1.90), ,I2 = 61%). Compared with no treatment, TCM seemed to increase the treatment success rate (UPSIT) (RR = 3.17, 95% CI (1.78, 5.65), ,I2 = 0%), but there was no statistically significant difference in improving the UPSIT score (MD = 3.44, 95% CI (−1.36, 8.24), ). Compared with drug therapy, TCM plus drug therapy appeared to increase the effective rate (ΔVAS) (RR = 2.36, 95% CI (1.41, 3.94), I2 = 0%), but there was no statistically significant difference in improving the TDI score (MD = 2.10, 95% CI (−1.99, 6.19), ). No significant differences in adverse reactions were reported between TCM and OTDT. Conclusion. TCM may be an effective treatment for PVOD. With a lack of high-quality RCTs, further large-scale and high-quality RCTs are still warranted.

  • Online Microextraction Coupled with HPLC-ABTS for Rapid Analysis of
           Antioxidants from the Root of Polygonum bistorta

    • Abstract: The root of Polygonum bistorta (PB) is a traditional Chinese medicinal plant material widely used in China. It has been commonly used for the treatment of hemostasis, detumescence, diarrhea, snake bite, and acute gastroenteritis. However, the research on the antioxidant properties and bioactive compounds from PB is inadequate. In the current research, an online microextraction (OLME) coupled with a high-performance liquid chromatography coupled with the 2,2-nitrogen-di (3-ethyl-benzothiazole-6-sulfonic acid) diammonium salt antioxidant assay (HPLC-ABTS) system for rapid analysis of antioxidants from PB was proposed. The PB sample (0.17 mg) was online extracted by mobile phase (acetonitrile and 0.2% acetic acid); a Poroshell 120 SB-Aq column was used for separation; then, an online ABTS assay system was used for screening the antioxidants. Finally, ten components were found in PB, and among them, eight components possessed antioxidant activities. Furthermore, five components (gallic acid, neochlorogenic acid, caffeic acid, chlorogenic acid, and an unknown compound) were proved as major antioxidants when compared with rutin as an antioxidant marker. The results showed that the developed OLME-HPLC-ABTS system was a simple, rapid, green, and efficient instrument for the screening of antioxidants from PB, which provides a powerful tool for the discovery of natural antioxidants in Chinese medicines.

  • Breast-Conserving Surgery in Triple-Negative Breast Cancer: A
           Retrospective Cohort Study

    • Abstract: Objectives. The aim of the study is to evaluate the efficacy and prognosis of neoadjuvant chemotherapy (NAC) combined with breast-conserving surgery (BCS) in treating triple-negative breast cancer (TNBC) and analyze the influencing factors and predictors of the efficiency and prognosis of NAC. Methods. A retrospective cohort study was conducted by dividing patients into two groups according to two different therapy methods. With BCS as the exposure factor, 46 cases were assigned to the exposed group and 80 cases to the nonexposed group. We compare the difference in operation-related indicators, postoperative complications, local recurrence rate, distant metastasis rate, and overall survival (OS) rate between the two groups. The factors affecting the efficiency and prognosis of NAC were analyzed by binary logistic regression, and the optimal cutoff value was determined by the area under the ROC curve (AUC). The survival curve was plotted, and the univariate log-rank test was performed to analyze the difference in OS between the two groups. The influencing factors of OS were analyzed by the Cox risk regression model. Results. NAC + BCS resulted in significantly less intraoperative blood loss, lower incidence of postoperative complications, and shorter operative time and length of hospital stay than that in NAC (). There was no significant difference in local recurrence, distant metastasis, or OS between the two groups (). Multivariate analysis showed that the clinical stage I and Ki-67 high expression were independent protective factors of the efficacy of NAC. The high expression of Ki-67 and nondecline expression of Ki-67 were independent risk factors of prognosis. Ki-67 high expression was an independent risk factor of OS (). The ROC curve showed that the AUC of Ki-67 for NAC efficacy, prognosis, and OS were 0.706, 0.820, and 0.687, respectively, with optimal cutoff values of 25.5%, 29.0%, and 32.5%, respectively. Survival analysis showed that the OS of patients with NAC + BCS was 73.9% and NAC + MRM was 70.0% (). In the low expression subgroup of Ki-67, the OS of the two groups were 100.0% and 77.8%, respectively (). In the high expression subgroup of Ki-67, the OS of the two groups were 53.8% and 63.6%, respectively ().Conclusions. NAC + BCS is a good method for treating TNBC, which has an obvious short-term effect and a good long-term prognosis. Clinical stage I and the high expression of Ki-67 are independent protective factors for the efficacy of NAC. The high expression of Ki-67 and nondecline expression of Ki-67 are independent risk factors of prognosis. Ki-67 is a potential predictor for the efficacy, prognosis, and OS of NAC in TNBC patients. The high expression of Ki-67 indicates better NAC efficacy, a poorer prognosis, and a lower OS.

           Cardiovascular Disease Patients: A Systematic Review and Meta-analysis

    • Abstract: Aims. This study aimed to examine the potential effectiveness of personalized nursing interventions on improving the heart-related quality of life of patients with CVDs versus an usual care. Design. A systematic review and meta-analysis. Data Sources. The study researched the article between January 2011 and December 2021 from four electronic databases: PubMed, Embase, Cochrane library, and Web of Science. Review Methods. Randomized controlled trials (RCTs) related to personalized nursing in CVDs population were included. The main variables were analyzed by standardized mean differences with 95% confidence intervals and heterogeneity was used by the I2 test and P value. Results. Of 734 studies, fourteen articles were eligible for this study. Personalized nursing significantly improved the quality of life [SMD = 0.39, 95% CI (0.29, 0.49)] with obvious heterogeneity (,I2 = 66.1%) which needs to be further subgroup analyzed. The nurse-led intervention was considered the main-related effect to influence the heterogeneity with value of 0.39 (I2 = 66.1%, ; Group 1: I2 = 48.4%, , and Group 2: I2 = 0.0%,. In addition, related results of athletic ability and mental health and follow-up and education in the intervention had higher level of quality of life compared to the control group [SMD = 0.27, 95% CI (0.10, 0.44); SMD = 0.21, 95% CI (0.04, 0.37); SMD = 0.39, 95% CI (0.29, 0.49) and SMD = 0.28, 95% CI (0.11, 0.44)]. Conclusion. Effectiveness studies of personalized care focus on more relevant outcomes have higher health outcomes, whereas evidence of the effectiveness of personalized nursing approach is still limited. Therefore, more and more high-quality RCT are needed.

  • Xuanhuang Runtong Tablets Relieve Slow Transit Constipation in Mice by
           Regulating TLR5/IL-17A Signaling Mediated by Gut Microbes

    • Abstract: This study aims to investigate the regulation effects of Xuanhuang Runtong tablets (XHRTs) on intestinal microbes and inflammatory signal toll receptor 5 (TLR5)/interleukin-17A (IL-17A) in STC mice. First, high-performance liquid chromatography (HPLC) was used to verify the composition of XHRT and quality control. Then, the defecation ability of STC mice was evaluated by measuring fecal water content and intestinal transit function. The pathological examination of colonic mucosa was observed by Alcian Blue and periodic acid Schiff (AB-PAS) staining. 16S ribosomal DNA (16S rDNA) genes were sequenced to detect the fecal microbiota. Western blotting, immunofluorescence, and real-time fluorescence quantitative PCR (qRT-PCR) were applied to detect the expression of aquaporin 3 (AQP3), connexin 43 (Cx43), TLR5, and IL-17A. The defecation function of the STC mice was significantly decreased. The amount of mucus secretion and the thickness of the colonic mucus layer were decreased, and the number of microbial species in the intestinal wall, such as Firmicutes/Bacteroidetes, anaerobic bacteria, and Alistipes, were also decreased. In addition, the expression of AQP3 and Cx43 was disordered, and the inflammatory factorsTLR5 and IL-17A were activated in the colon. The changes in the above indicators were significantly reversed by XHRT. This study demonstrates that XHRT provides a new strategy for the treatment of slow transit constipation by regulating the activation of the intestinal inflammatory signal TLR5/IL-17A mediated by gut microbes.

  • Profiling Inflammatory Biomarkers following Curcumin Supplementation: An
           Umbrella Meta-Analysis of Randomized Clinical Trials

    • Abstract: Objective. Several meta-analyses have shown that curcumin can reduce inflammatory biomarkers, but the findings are inconsistent. The objective of the present umbrella meta-analysis was to provide a more accurate estimate of the overall effects of curcumin on inflammatory biomarkers. Methods. The following international databases were systematically searched until March 20, 2022: PubMed, Scopus, Embase, Web of Science, and Google Scholar. A random-effects model was applied to evaluate the effects of curcumin on inflammatory biomarkers. Meta-analysis studies investigating the effects of curcumin supplementation on inflammatory biomarkers with corresponding effect sizes (ES) and confidence intervals (CI) were included in the umbrella meta-analysis. GRADE (Grading of Recommendations Assessment, Development, and Evaluation) was used to evaluate the certainty of evidence. Results. A meta-analyses of ten studies with 5,870 participants indicated a significant decrease in C-reactive protein (CRP) (ES = −0.74; 95% CI: −1.11, −0.37, ; I2 = 62.1%, ), interleukin 6 (IL-6) (ES = −1.07; 95% CI: −1.71, −0.44, ; I2 = 75.6%, ), and tumour necrosis factor α (TNF-α) levels (ES: −1.92, 95% CI: −2.64, −1.19, ; I2 = 18.1%, ) following curcumin supplementation. Greater effects on CRP and TNF-α were evident in trials with a mean age>45 years and a sample size>300 participants. Conclusion. The umbrella of meta-analysis suggests curcumin as a promising agent in reducing inflammation as an adjunctive therapeutic approach in diseases whose pathogenesis is related to a higher level of inflammatory biomarkers.

  • Investigation of the Possible Causes of NRBC in ICU Patients and the
           Dynamic Trend of NRBC Count in Survival and Death Patients or with
           Different Underlying Diseases: A Retrospective Study

    • Abstract: Background. The mortality of intensive care unit (ICU) patients ranges from 5% to 30%, and nucleated red blood cells (NRBCs) were revealed to be related to mortality. However, few studies have discussed the causes of NRBC or compared the dynamic count among patients with underlying diseases. Aim. To explore the possible causes of NRBC in ICU patients and the dynamic trends between survival and death groups and underlying disease subgroups. Methods. A total of 177 ICU patients were retrospectively included. The possible causes of NRBC in ICU patients were discussed. The relationship between NRBC and in-hospital mortality and the dynamic trend of NRBC during hospitalization between the survival and death groups and underlying disease subgroups were compared. Results. The Acute Physiology and Chronic Health Evaluation II (APACHE II) score and Sequential Organ Failure Assessment (SOFA) score in the NRBC-positive group were higher (23.52 ± 9.39 vs. 19.62 ± 7.59; 13.50 (9.00–17.50) vs. 8.00 (6.00–12.00)). Red blood cell count (RBC), hemoglobin (Hb) level, oxygen saturation (SO2), oxygenation index (OI), and serum protein level were lower in the NRBC-positive group. However, D-dimer (D-D), liver and kidney function indices, lactate dehydrogenase (LDH), C-reactive protein (CRP), and procalcitonin (PCT) were higher than those in the NRBC-negative group. Correlation analysis showed that NRBC count was positively correlated with alkaline phosphatase (ALP) and red blood cell distribution width (RDW) and negatively correlated with SO2 (r = 0.431, ;r = 0.363, ;r = −0.335, ). The mortality rate in the NRBC-positive group was higher, and the median survival time was shorter than that in the NRBC-negative group (77.9% vs. 95.7%, ; 15 days vs. 8.5 days, ). Univariate and multivariate Cox regression analyses showed that NRBC was an independent risk factor for in-hospital mortality (HR: 1.12 (1.03–1.22), ). The NRBC count had different hazard ratios (HRs) for in-hospital mortality in the subgroups. Locally weighted scatterplot smoothing (LOWESS) analysis revealed that the NRBC count in the death group was higher and had a sharp upward trend before death, whereas that in the survival group was negative or stayed at a low level. The changing trend of the NRBC count was different in patients with different underlying diseases. Conclusion. The possible cause of NRBC in ICU patients was related to inflammation and hypoxia. The persistently high level and rapid upward trend of NRBC counts are risk factors for in-hospital mortality in ICU patients. The changing trend of the NRBC count varied in patients with different underlying diseases.

  • Yunvjian Improves Glucose and Insulin Function in Diabetic Rats by
           Regulating Gastric Emptying Function

    • Abstract: Background. Diet acts on the human body through digestion in the stomach and absorption in the intestines. Thus, the emptying of the stomach should be the focus of the research mechanism of the combined medicine and food treatment of diabetes. The emptying function of the stomach and the secretion of related hormones may be the key points of traditional Chinese medicine. In the clinic, Yunvjian is a famous traditional Chinese formula for preventing and curing diabetes. However, the pharmacological action and mechanism of Yunvjian are also need to be probe. Objective. To assess the effect of Yunvjian on glucose, insulin level and gastric emptying function and related hormones on high-fat diet combined with STZ-induced diabetic rats. Methods. High-fat diet combined with STZ was used to construct type 2 diabetes mellitus (T2DM) rats model and received a 4-week Yunvjian administration. The animals were divided into 6 groups, respectively, as the Control group, the DM group, the DM + Acarbose group, the DM + YNH group, and the DM + YNL group. Radionuclide single-photon emission computed tomography (SPECT) technology was used to observe the gastric emptying rate and half-empty time; blood was took to test fasting insulin, and then the insulin resistance index (HOMA-IR) was calculated; HE staining was performed to detect islets and gastric antrum, immunohistochemical staining was performed to detect the number and morphology of pancreatic β cells and gastric antrum Cajal cells, and the average optical density was calculated; the expression of ghrelin hormone in gastric antrum and serum was detected by ELISA and immunofluorescence; the expression of GHRS mRNA in gastric antrum was detected by RT-PCR method. Results. Yunvjian could significantly improve the glucose level and insulin function of rats. Compared with the DM group, Yunvjian was beneficial to low fasting blood glucose (FBG) (), increased glucose tolerance, and improved islet function at the same time (). At the same time, compared with the DM group (25.02 ± 0.05, 44 ± 12.33), the emptying rate of the DM + YNH group was significantly faster (64.98 ± 0.12), and the half row time was shortened (26 ± 8.29, ). The gastric ghrelin levels in each group of Yunvjian increased with different degrees compared with the DM group (616.2 ± 26.23), especially in the DM + YNH group (863.51 ± 23.76, ). Correspondingly, the expression of gastric GHSR mRNA in the DM + YNH and DM + YNL groups increased significantly compared with the DM group ().Conclusions. Yunvjian can effectively control glucose and improve islet function, which may be closely related to its influence on gastric emptying function and related hormone secretion regulation.

  • Effects of Different Vegetable Oils on the Nonalcoholic Fatty Liver
           Disease in C57/BL Mice

    • Abstract: Background. Nonalcoholic fatty liver disease (NAFLD) is the most common hepatic disorder, affecting 22–28% of the adult population and more than 50% of obese people all over the world. Modulation of the fatty acids in diet as a means of prevention against nonalcoholic fatty liver disease in animal models (NAFLD) remains unclear. The treatment of NAFLD has not been described in specific guidelines so far. Thus, the justification for the study is to check modifications in macronutrients composition, fatty acids, in particular, play a significant role in the treatment of NAFLD regardless of weight loss. Aim. To investigate different vegetable oils in prevention and progression of NAFLD in animal models. Methods. For the experiment were used fifty C57BL/6J mice male fed with high fat and fructose diet (HFD) to induce the NAFLD status and they received different commercial vegetable oils for 16 weeks to prevent steatosis. Liver steatosis and oxidative stress parameters were analyzed using biochemical and histological methods. Fatty acids profile in the oils and in the liver samples was obtained. Results. The high fat and fructose diet led to obesity and the vegetable oils offered were effective in maintaining body weight similar to the control group. At the end of the experiment (16 weeks), the HFHFr group had a greater body weight compared to control and treated groups (HFHFr: 44.20 ± 2.34 g/animal vs. control: 34.80 ± 3.45 g/animal; ; HFHFr/OL: 35.40 ± 4.19 g/animal; HFHFr/C: 36.10 ± 3.92 g/animal; HFHFr/S: 36.25 ± 5.70 g/animal; ). Furthermore, the HFD diet has caused an increase in total liver fat compared to control (). Among the treated groups, the animals receiving canola oil showed a reduction of hepatic and retroperitoneal fat (). These biochemical levels were positively correlated with the hepatic histology findings. Hepatic levels of omega-3 decreased in the olive oil and high fat diet groups compared to the control group, whereas these levels increased in the groups receiving canola and soybean oil compared to control and the high fat groups. Conclusion. In conclusion, the commercial vegetable oils either contributed to the prevention or reduction of induced nonalcoholic fatty liver with high fat and fructose diet, especially canola oil.
