  • The expression level of COX7C associates with venous thromboembolism in
           colon cancer patients
    • Abstract: Venous thromboembolism (VTE) is a common complication of colon cancer. In the present study, we aimed to explore the association of the oncogene COX7C to VTE in colon cancer patients. Samples from 580 patients were examined histologically for VTE and pathological characteristic of cancer. Gene mutation and expression analysis were performed using polymerase chain reaction-based assays to evaluate genes related to VTE, including COX7C. Univariate analysis between clinical pathological factors and VTE was conducted. Logistic regression analysis was performed for the prediction of VTE by pathological factors and gene expressions. Among patients investigated, a total of 56 patients had VTE. COX7C had a significant correlation with VTE (p < 0.001). Despite a correlation between tumor size, invasion depth of tumor, lymph node metastasis, lymph node metastasis, distant metastasis, lymphovascular invasion, histologic type and pathology type, Ki-67, and some other genes, to VTE (p > 0.05), only COX7C expression demonstrated significance in its ability to predict VTE. Here, we show that COX7C upregulation strongly correlates with VTE in colon cancer, which implicates its role as a biomarker and therapeutic target of VTE in colon cancer.

  • Clinical practice: chimeric antigen receptor (CAR) T cells: a major
           breakthrough in the battle against cancer
    • Abstract: Chimeric antigen receptor (CAR) T cell therapy has come of age, offering a potentially curative option for patients who are refractory to standard anti-cancer treatments. The success of CAR T cell therapy in the setting of acute lymphoblastic leukemia and specific types of B cell lymphoma led to rapid regulatory approvals of CD19-directed CAR T cells, first in the United States and subsequently across the globe. Despite these major milestones in the field of immuno-oncology, growing experience with CAR T cells has also highlighted the major limitations of this strategy, namely challenges associated with manufacturing a bespoke patient–specific product, intrinsic immune cell defects leading to poor CAR T cell function as well as persistence, and/or tumor cell resistance resulting from loss or modulation of the targeted antigen. In addition, both on- and off-tumor immunotoxicities and the financial burden inherent in conventional cellular biomanufacturing often hamper the success of CAR T cell-based treatment approaches. Herein, we provide an overview of the opportunities and challenges related to the first form of gene transfer therapy to gain commercial approval in the United States. Ongoing advances in the areas of genetic engineering, precision genome editing, toxicity mitigation methods and cell manufacturing will improve the efficacy and safety of CAR T cells for hematologic malignancies and expand the use of this novel class of therapeutics to reach solid tumors.

  • The effects of apoptosis and apelin on lymph node metastasis in invasive
           breast carcinomas
    • Abstract: This study aimed to evaluate the biological and clinical significance of apelin-36 in breast cancer and to compare apelin-36 expression and apoptotic index in both breast tissue and metastatic lymph nodes in patients with invasive breast carcinoma. In this study, both tumor tissue and metastatic lymph nodes of the same patient were collected from 60 cases of invasive breast carcinoma patients (IDC, ILC) and 20 cases of normal breast tissue with no tumor from mammoplasty were used as the control group. The expression of apelin was examined with immunohistochemically, and the apoptotic index was examined with TUNEL methods. According to Kruskal–Wallis analysis, there was a significant difference between IDC and the control group when the apelin expression was compared between the breast tissues (p = 0.001). There were significant differences between the three groups when comparing relationships with apoptotic index (p < 0.001). According to the Mann–Whitney U test, both tumor size and expression of apelin in lymph nodes in ILCs were significantly higher than IDCs. (p = 0.026, p = 0.024, respectively). According to correlation analysis, there was a good correlation between the expression of apelin in breast tissue and apelin expression in lymph nodes (p = 0.000). It is also found a similar relationship in terms of the apoptotic index (p = 0.000). In addition, the negative correlation was found between apelin expression and the apoptotic index in breast tissues (p = 0.003). Based on these results, apelin-36 can be used as a marker for determining the metastasis potential in invasive breast cancer.

  • IGFBP3 as an indicator of lymph node metastasis and unfavorable prognosis
           for papillary thyroid carcinoma
    • Abstract: Lymph node metastasis (LNM) is a usual event in papillary thyroid carcinoma (PTC) patients, which usually leads to poor prognosis. However, the molecular mechanisms of LNM remain unclear. Thus, we aimed to screen the possible key genes in the progression of LNM in PTC patients and further validate their roles. The study involved two phases: a discovery phase and a validation one. In the former phase, the candidate genes were screened by using bioinformatics methods. In the latter one, the genes were firstly assessed in a cohort from the cancer genome atlas (TCGA) to evaluate the associations of their expressions with clinical features and the prognostic values, and then, they were assessed at protein levels by using an immunohistochemical assay. Consequently, IGHBP3 was selected as the candidate gene, which might be enriched in several metabolism-related pathways and cancer progression-related pathways. High expressions of IGHBP3 have an association with gender, advanced clinical stages, high T stages, and the presence of LNM. Survival analysis indicated that IGHBP3 may affect the prognosis of PTC patients. The use of a tissue chip confirmed the view that IGHBP3 might play a crucial role in the LNM of PTC. In conclusion, IGHBP3 might be involved in the development of LNM in PTC patients. IGHBP3 over-expression might be a novel indicator and a potential target for PTC therapy.

  • Analysis of pathological changes and related factors in liver tissue of
           HBeAg-negative patients with low HBsAg levels
    • Abstract: The relationship between pathological changes in liver tissue and the level of hepatitis B surface antigen (HBsAg) remains unclear. This study aimed to analyze the pathological changes in liver tissue and its related factors in patients with low-level HBsAg in order to provide a basis for judging the condition of these patients. A retrospective study was performed on 96 chronic hepatitis B patients with HBsAg levels < 1400 IU/ml and > 0.05 IU/ml. The histopathological examination of these patients was conducted. Univariate and multivariate analyses were used to determine risk factors for pathological changes. Among the 96 patients, 57.3% (55) had inflammatory events ≥ G2 and 33.4% (33) had fibrosis ≥ S2. HBV infection duration (p = 0.001) and splenic vein diameter (p = 0.001) were independent risk factors of liver inflammation (≥ G2) in patients with low-level HBsAg, while AST (p = 0.006) and PLT (p = 0.005) were independent risk factors of liver fibrosis (≥ S2). Moreover, HBV infection duration (p < 0.001) and spleen vein (p = 0.001) were independent factors of potential antiviral treatment. Liver inflammation and fibrosis are still common in patients with low-level HBsAg; thus, the monitoring and appropriate antiviral treatment cannot be ignored.

  • Association between complement 4 copy number variation and systemic lupus
           erythematosus: a meta-analysis
    • Abstract: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by multiple genetic mutations. Complement 4 (C4) copy number variation (CNV) is a target-of-interest located on chromosome 6. C4 encodes for either of the two C4 paralogs, C4A or C4B, and low C4 levels have been associated with SLE activity. In this study, we conducted a meta-analysis to comprehensively understand the role of C4 CNV in SLE. Three databases (PubMed, Embase, and Web of Science) were searched for relevant studies. Two investigators independently extracted and evaluated data from eligible studies. Associations between C4 CNV and SLE were estimated by odds ratios (OR) and 95% confidence intervals (95% CI). Further analysis was conducted using the STATA 12.0 software. A total of eight case-control studies were included in the analysis with 4107 SLE patients and 5889 healthy controls. Six studies used TaqMan real-time PCR to genotype C4 CNV, with 1 study used paralog ratio test and other one used multiplex ligation-dependent probe amplification (MLPA). Lower total C4 CNV and C4A CNV were associated with SLE in the overall analysis (pooled OR: 1.55, 95% CI: 1.23–1.95; pooled OR: 1.86, 95% CI: 1.51–2.29). The subgroup analysis found that total C4 CNV and lower C4A CNV were significantly associated with SLE in Caucasians (pooled OR: 1.84, 95% CI: 1.60–2.12; pooled OR: 2.23, 95% CI:1.92–2.59). However, the association was not detected in East Asians. Lastly, SLE was not associated with C4B CNV, long C4 CNV, or short C4 CNV. The meta-analysis confirmed that lower total C4 CNV and lower C4A CNV are associated with SLE in certain populations. Future studies should consider other ethnic groups to further investigate the relationship between the C4 gene and SLE.

  • LncPRYP4-3 serves as a novel diagnostic biomarker for dissecting subtypes
           of metabolic associated fatty liver disease by targeting RPS4Y2
    • Abstract: Longitudinal studies have improved current diagnostics and management of metabolic associated fatty liver disease (MAFLD) patients by liver biopsy and therapeutic intervention, yet the deficiency of biomarker spectrum for dissecting subtypes largely hinders the symptomatic treatment. We originally enriched serum from peripheral blood of 618 healthy donors (HD) and 580 MAFLD (400 NAFL, 180 NASH) patients according to multiple clinicopathological indicators. Microarray profiling and qRT-PCR were conducted to identify lncRNAs as candidate biomarkers of MAFLD. Then, we analyzed the matching score of the indicated lncRNA with CAP or MAFLD-associated pathological parameters as well. Additionally, we took advantage of interaction network together with gene expression profiling analysis to further explore the underlying target genes of the identified lncRNA. Herein, we found CAP in nearly all of the NAFL (399/400) and NASH (179/180) patients was higher than that in the HDs (611/618). The differentially expressed lncRNAs were involved in multiple metabolic or immunologic processes by regulating MAFLD-associated pathways. Of them, serum lncPRYP4-3 was identified as a novel candidate biomarker of MAFLD, which was further confirmed by correlation analysis with clinical indicators. Thereafter, we deduced PRS4Y2 was a candidate target of lncPRYP4-3 and mediated the dysfunction in NAFL and NASH patients. Serum lncPRYP4-3 served as a novel biomarker of MAFLD and helped distinguish the subtypes and benefit precise intervention therapy. Our findings also provided overwhelming new evidence for the alteration in biological processes and gene ontology in MAFLD patients.

  • Evaluation of different proton pump inhibitors combined with bismuth
           quadruple regimens in Helicobacter pylori eradication
    • Abstract: To evaluate the efficacy and economics of different proton pump inhibitors (PPIs) combined with bismuth quadruple regimens for Helicobacter pylori (Hp) eradication, a retrospective analysis method was used to collect Hp-positive patients who were treated with a bismuth-containing quadruple regimen (PPIs + amoxicillin + furazolidone + colloid pectin bismuth) from the outpatient department of gastroenterology in our hospital from January to June 2017. A total of 1410 patients were included in the study and divided into four groups according to different PPIs: group A (pantoprazole sodium enteric-coated capsules, 352 cases), group B (esomeprazole magnesium enteric-coated tablets, 462 cases), group C (pantoprazole sodium enteric-coated tablets, 392 cases) and group D (rabeprazole sodium enteric-coated tablets, 204 cases). The eradication rate of Hp and cost-saving in each group were then compared. There were no significant differences of gender (P = 0.526) and age (P = 0.366) between each Hp treatment regimen. The eradication rates of groups A, B, C and D were 91.48%, 89.83%, 86.73% and 90.69%, respectively. No statistical differences of Hp eradication rates were observed between each group yet (P > 0.05). However, the cost of group A was the lowest. In the present study, the Hp eradication rates between different PPIs regimens were similar in treating Hp infection. Nevertheless, the point in favor of pantoprazole capsules is the slightly higher Hp eradication rate and lower drug cost than other PPIs, which provides a significant evidence for the clinical medication decision in treating Hp infection.

  • Organ-specific manifestations of COVID-19 infection
    • Abstract: Although COVID-19 presents primarily as a lower respiratory tract infection transmitted via air droplets, increasing data suggest multiorgan involvement in patients that are infected. This systemic involvement is postulated to be mainly related to the SARS-CoV-2 virus binding on angiotensin-converting enzyme 2 (ACE2) receptors located on several different human cells. Lung involvement is the most common serious manifestation of the disease, ranging from asymptomatic disease or mild pneumonia, to severe disease associated with hypoxia, critical disease associated with shock, respiratory failure and multiorgan failure or death. Among patients with COVID-19, underlying cardiovascular comorbidities including hypertension, diabetes and especially cardiovascular disease, has been associated with adverse outcomes, whereas the emergence of cardiovascular complications, including myocardial injury, heart failure and arrhythmias, has been associated with poor survival. Gastrointestinal symptoms are also frequently encountered and may persist for several days. Haematological complications are frequent as well and have been associated with poor prognosis. Furthermore, recent studies have reported that over a third of infected patients develop a broad spectrum of neurological symptoms affecting the central nervous system, peripheral nervous system and skeletal muscles, including anosmia and ageusia. The skin, the kidneys, the liver, the endocrine organs and the eyes are also affected by the systemic COVID-19 disease. Herein, we provide a comprehensive overview of the organ-specific systemic manifestations of COVID-19.

  • Clinical significance of serum miR-768-3p in HBV-related hepatocellular
           carcinoma and its potential mechanism
    • Abstract: The purpose of this study was to reveal the clinical diagnostic and prognostic value of miR-768-3p in HBV-related HCC and to investigate its effect on the biological function of HCC. Quantitative real-time polymerase chain reaction was used to detect the expression level of miR-768-3p in subjects’ serum. The receiver operating characteristics curve (ROC) evaluated the diagnostic value of miR-768-3p in patients. A Chi-square test was used to analyze the relationship between miR-768-3p and clinical data of patients. Kaplan–Meier survival and Cox regression analysis assessed the prognostic value of miR-768-3p in HCC. Finally, CCK-8 and Transwell assays were used to demonstrate the effect of miR-768-3p on HBV-related HCC function. Serum miR-768-3p was significantly lower in HCC patients than in healthy controls and chronic hepatitis B (CHB) patients. ROC curve suggested that serum miR-768-3p has an important diagnostic value for HBV-related HCC and can significantly differentiate HCC patients from healthy controls, and it can also diagnose HCC patients from CHB patients. Cox analysis confirmed that miR-768-3p was an independent risk factor. Low expression of miR-768-3p was associated with Tumor, Node, Metastasis stage, Barcelona Clinic Liver Cancer stage, and poor prognosis in HCC patients. Finally, cell function experiments confirmed that high expression of miR-768-3p could inhibit cell proliferation, migration, and invasion. All experiments confirmed that miR-768-3p can inhibit the proliferation, migration, and invasion of HBV-related HCC cells, and the low expression of miR-768-3p can be used as a potential diagnostic and prognostic biomarker for HBV-related HCC.

  • Expression of BAFF and BAFF receptors in primary Sjögren’s syndrome
           patients with ectopic germinal center-like structures
    • Abstract: B cell-activating factor (BAFF) is an essential cytokine in primary Sjögren’s syndrome (pSS) physiopathology. It has been reported that pSS patients develop germinal center-like (GC-like) structures in their minor salivary glands (MSGs). BAFF, BAFF-R, TACI, and BCMA expression was analyzed in MSGs from 29 subjects (nonspecific chronic sialadenitis and focal lymphocytic sialadenitis with the presence [pSS-GC(+)] or absence [pSS-GC(−)] of GC-like structures). Twenty-four percent of patients showed ectopic GC-like structures and a high focus score [p < 0.001 vs pSS-GC(−)]. BAFF serum levels (sBAFF) were high in pSS patients (p = 0.025 vs healthy subjects). However, the pSS-GC(−) group showed higher sBAFF levels than pSS-GC(+) patients. BAFF and BAFF-R glandular expression levels were higher in pSS-GC(+) patients, without significant differences compared to pSS-GC(−) patients. Soluble levels of BAFF correlated with anti-La/SSB antibodies and disease duration. Our results showed that BAFF could contribute to focal lymphocytic infiltration. The role of BAFF-binding receptors in MSGs is proposed as a mechanism for the possible establishment of ectopic GC-like structures and disease progression in some patients. In conclusion, this study supports previous evidence that considers the active BAFF system role in the pathogenesis of pSS and the need for strong biomarkers in this disease.

  • Slit2 is a potential biomarker for renal impairment in systemic lupus
    • Abstract: Slit2 glycoprotein has been described to regulate the inflammatory response and be involved in autoimmune diseases. Here, we investigated the expression of Slit2 and its potential significance in systemic lupus erythematosus (SLE). A total of 103 patients with SLE participated in our study. The levels of serum Slit2 were measured by enzyme-linked immunosorbent assay, and the expression of Slit2 in renal tissue was detected by immunohistochemistry. Patients with active disease had higher levels of serum Slit2 than patients with inactive disease and controls. Patients with sole skin impairment or sole renal impairment or both skin and renal impairment had higher levels of serum Slit2 than patients with neither skin nor renal impairment. Patients with chronic kidney disease (CKD) had higher levels of serum Slit2 than patients with no CKD. Levels of serum Slit2 in patients with active disease were positively correlated with the SLE Disease Activity Index, complement C4, and anti-dsDNA antibody. Levels of serum Slit2 in patients with CKD were positively correlated with serum creatinine, urine protein, and glomerular filtration rate. The expression of Slit2 and its receptor Roundabout1 (Robo1) in the renal tissue of patients with lupus nephritis were higher than controls. Moreover, renal Slit2 was positively correlated with renal chronic index. Our data indicated that Slit2 may contribute to renal impairment and this may be a potential biomarker for SLE.

  • The diagnostic role of AIM2 in Kawasaki disease
    • Abstract: Kawasaki disease (KD), a systemic vasculitis in children, may bring serious complications. However, the etiology of KD remains unclear. AIM2, an intracellular receptor, plays a vital role during the infection caused by a variety of pathogens. However, its role in KD remains unclear. The principal aim of the present research is to concentrate on the relation between AIM2 and KD. We detected the levels of AIM2, IL-18 and IL-1β in all subjects by ELISA. The conventional inflammatory indices were detected in all subjects, such as WBC, HB, CRP and so on. The serum concentrations of AIM2, IL-18 and IL-1β were notably upregulated in the KD group compared to the febrile group and healthy group, respectively. And the three indicators in the KD patients were greatly reduced after interpreted with IVIG. Furthermore, the expressions of IL-18 and IL-1β were positively correlated with AIM2. Meanwhile, the cutoff value of serum AIM2 level for the diagnosis of KD was 541.90 ng/L with the specificity of 60% and sensitivity of 92.5%, compared to the febrile controls. And the area under curve (AUC) of AIM2 was 0.771. And no difference was observed in patients with CALs when compared with patients without CALs. The serum AIM2, IL-18 and IL-1β might play a critical role during the progress of KD. AIM2 can be considered as a candidate indicator for Kawasaki disease diagnosis.

  • Pharmacodynamic biomarkers in metronomic chemotherapy: multiplex cytokine
           measurements in gastrointestinal cancer patients
    • Abstract: Metronomic chemotherapy has shown promising antitumor activity in a number of malignancies. We previously reported a phase II clinical trial of metronomic UFT (a 5-fluorouracil prodrug; 100 mg/twice per day p.o.) and cyclophosphamide (CTX; 500 mg/m2 i.v. bolus on day 1 and then 50 mg/day p.o.) plus celecoxib (200 mg/twice a day p.o.) in 38 patients with advanced refractory gastrointestinal tumors. The mechanisms of action of metronomic chemotherapy include inhibition of angiogenesis, direct cytotoxic effects on cancer cells, and, at least for drugs such as CTX, activation of the immune system. To further evaluate the latter, we carried out an immune system multiplex 14-cytokine profiling of plasma samples that were available (for day 0, day 28, and day 56) from 31 of the 38 patients in the above-noted clinical trial. Our results show that pre-treatment plasma-level cutoffs of interferon gamma (> 12.84 pg/ml), sCD40L (< 2168 pg/ml), interferon alpha 2 (> 55.11 pg/ml), and IL-17a (< 15.1 pg/ml) were predictive markers for those patients with better progression-free survival (p < .05 for each cytokine). After 28 days of metronomic therapy, the plasma levels of sCD40L, IL-17a, and IL-6 (< 130 pg/ml) could serve as predictors of improved progression-free survival, as could levels interferon gamma and sCD40L after 56 days of therapy. We observed minimal changes in cytokine profiles, from baseline, as a consequence of the metronomic therapy, with the exception of an elevation of IL-6 and IL-8 levels 28 days (and 56 days) after treatment started (p < 0.05). Our results indicate that a selective cytokine elevation involves IL-6 and IL-8, following metronomic chemotherapy administration. In addition, interferon gamma and sCD40L may be potential biomarkers for gastrointestinal cancer patients that are likely to benefit from metronomic chemotherapy. Our study contributes to our understanding of the mechanisms of action of metronomic chemotherapy, and the cytokine profiling we describe may guide future selection of gastrointestinal cancer patients for UFT/CTX/celecoxib combination metronomic chemotherapy.

    • Abstract: Transarterial chemoembolization (TACE) induces a change in serum HIF-1α level in patients with hepatocellular carcinoma (HCC). This study investigated the prognostic value of change in serum HIF-1α following TACE treatment in HCC patients. A total of 61 hepatocellular carcinoma patients treated with TACE were included. Peripheral blood samples were collected within 1 week before and after TACE to determine the serum levels of hypoxia-inducible factor-1α (HIF-1α) and vascular endothelial growth factor-A (VEGF-A) by enzyme-linked immunosorbent assay (ELISA). Serum HIF-1α change was calculated as follows: ∆HIF-1α = (HIF-1α (pre-TACE) − HIF-1α (post-TACE))/HIF-1α (pre-TACE). Likewise, serum VEG-F change was calculated as follows: ∆VEG-F = (VEG-F (pre-TACE) − VEG-F(post-TACE))/VEG-F (pre-TACE). Based on the cutoffs (0.25) determined by the maximum Youden’s index in receiver operating characteristic analysis, the patients were grouped into the low ∆HIF-1α group (< 0.25) and the high ∆HIF-1α group (> 0.25). After TACE treatment, HIF-1α was significantly decreased (pre-TACE 1901.62 vs. post-TACE 621.82 pg/ml, P < 0.01) but VEGF-A was significantly increased (pre-TACE 60.80 vs. post-TACE 143.81 pg/ml, P < 0.01). Multivariate logistic regression analysis demonstrated that ∆HIF-1α was a prognostic factor (OR = 58.09, 95% CI: 1.59–2127.32, P = 0.027) for the TACE treatment response. Furthermore, multivariate Cox regression analysis revealed that ∆HIF-1α was a prognostic factor for progression-free survival (PFS) (HR = 0.30, 95% CI: 0.14–0.66, P = 0.003) and overall survival (OS) (estimated HR = 0.38, 95% CI: 0.16–0.93, P = 0.034). Kaplan–Meier survival analysis showed that the high ∆HIF-1α group was more likely to have longer PFS (log-rank test, P = 0.004) and OS (log-rank test, P = 0.002) than the low ∆HIF-1α group. The change in serum HIF-1α level following TACE is a prognostic factor associated with the TACE treatment response, PFS, and OS in HCC patients following TACE.

  • Decreased serum myonectin concentrations in diabetic nephropathy patients
    • Abstract: Myonectin is a newly discovered myokine correlated with diabetes. Diabetic nephropathy (DN), which is diagnosed according to albuminuria, is one of the most common microvascular complications of diabetes. Albuminuria predisposes to future cardiovascular diseases and mortality. The aim of this study is to assess the association between serum myonectin concentrations with DN. A total of 188 patients with type 2 diabetes (T2DM) and 66 control subjects were enrolled in this investigation. T2DM patients were divided into three groups: normoalbuminuria (n = 84), microalbuminuria (n = 70), and macroalbuminuria (n = 34) according to urine albumin-to-creatinine ratio (ACR). T2DM patients showed lower serum myonectin concentrations compared with the controls. Serum myonectin concentrations were significantly decreased in macroalbuminuria group than in normoalbuminuria and microalbuminuria groups. In addition, microalbuminuria group had decreased serum myonectin concentrations compared with normoalbuminuria group. Logistic regression analysis demonstrated a correlation between serum myonectin and a decreased risk of T2DM and DN. Simply linear regression analysis indicated serum myonectin was negatively correlated body mass index (BMI), total cholesterol, low-density lipoprotein cholesterol, blood urea nitrogen, creatinine, uric acid, and ACR, and positively correlated with glomerular filtration rate, insulin treatment. BMI, ACR, and insulin treatment were still correlated with the serum myonectin after a multiple linear regression analysis. Our investigation indicates serum myonectin is decreased in DN patients and correlated with renal function.

  • Imaging characteristics and prognostic values of hepatic epithelioid
           hemangioendothelioma on 18 F-FDG PET/CT
    • Abstract: Hepatic epithelioid hemangioendothelioma (HEHE) is a low-to-intermediate-grade malignant mesenchymal tumor. The diagnostic and prognostic values of 2-[18F] fluoro-2-deoxy-D-glucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) to patients with HEHE have not been fully validated. Patient survival outcomes (including overall survival [OS] and progression-free survival [PFS]), lesions characteristics and semi-quantitative parameters, in terms of maximum standardized uptake value (SUVmax), peak SUV (SUVpeak), total lesion glycolysis (TLG) and metabolic tumor volume (MTV) on 18F-FDG PET/CT of 20 cases with HEHE were measured and analyzed. A total of 310 liver lesions were detected (excluding the diffuse-type lesions in 3 cases). Most lesions had higher SUVmax in delayed imaging than in early imaging (P = 0.013). Patients with multiple organs involved had higher death rate (P = 0.022), higher progression rate (P = 0.020), shorter OS (P = 0.011), larger lesion SUVmax (P = 0.048) and TLG (P = 0.033) than those with only liver involved. The area under curves (AUCs) from the receiver operating characteristic (ROC) curve analysis were 0.960, 0.949, 0.980 and 0.960 for SUVmax, SUVpeak, TLG and MTV, respectively, in predicting OS (P = 0.005, 0.008, 0.001 and 0.024, respectively). For predicting PFS, the AUCs were 0.791, 0.824, 0.857 and 0.813 (P = 0.036, 0.019, 0.010 and 0.024), respectively. Dual-time-point imaging may improve lesions detectability. Patients with multiple organ involved had worse prognosis. The higher SUVmax, SUVpeak, TLG and MTV of lesions, the worse prognosis of patients were found.

  • The risk of cardiovascular complications in inflammatory bowel disease
    • Abstract: Inflammatory bowel disease (IBD) is a chronic, relapsing disease of unknown etiology involving gastrointestinal tract. IBD comprises two main entities: ulcerative colitis and Crohn’s disease. Several studies showed increased risk of cardiovascular complications in chronic inflammatory disorders, especially during IBD relapses. Endothelium plays a role in physiologic regulation of vascular tone, cell adhesion, migration and resistance to thrombosis. Also, its dysfunction is associated with increased risk of atherosclerosis development. There are several potential links between chronic IBD-related inflammatory processes and the risk of cardiovascular disease, but insight into pathogenetic pathways remains unclear. We present the current concepts and review of adult and pediatric studies on the risk of CVD in IBD.

  • TNM staging for GIT cancers is correlated with the level of MMPs and
    • Abstract: Gastrointestinal (GIT) cancers represent the third common cancers worldwide, characterized by rapid progression and higher mortality rate. Matrix metalloproteinases (MMPs) play an important role in cancer metastases. The present study was conducted to estimate and evaluate the role of MMP-7, -9, -10 and -12 and TGF β1 along with conventional biomarkers (CEA and CA19-9) in gastric (GC), pancreatic (PC) and colorectal cancer (CRC) staging system according to tumor size (T), included lymph node (N) and metastasis (M). Seventy-five patients were divided into GC group (n = 25), PC group (n = 25), CRC group (n = 25) and twenty-five healthy subjects (control group). Serum levels of MMP-7, -10 and -12 were assayed simultaneously using luminex multiplex technique. Also, MMP-9, TGF-β1, CA19-9 and CEA were determined by ELISA. MMP-7,-9,-10, -12, TGF-β1 and CEA levels were significantly (p < 0.001) higher in GIT cancer groups compared with control. CA19-9 was significantly (p < 0.001) higher in PC and CRC groups compared with control. MMP-9 was positively correlated with TNM staging in PC patients. MMP-12 was negatively correlated with T in PC and positively correlated with M in CRC group. CA 19-9 was positively correlated with M grade in CRC. Depending on the estimated cutoff values of area under receiver curve; CA19-9 and MMP-7 were excellent diagnostic markers in PC, CEA and MMP-7 were excellent in CRC, and MMP-7 and MMP-9 were excellent in GC. Our findings indicated the clinical utility of MMPs in diagnosis and TNM staging of GIT cancers along with CEA and CA19-9.

  • Development and validation of a metabolic gene signature for predicting
           overall survival in patients with colon cancer
    • Abstract: The reprogramming of cellular metabolism is a hallmark of tumorigenesis. However, the prognostic value of metabolism-related genes in colon cancer remains unclear. This study aimed to identify a metabolic gene signature to categorize colon cancer patients into high- and low-risk groups and predict prognosis. Samples from the Gene Expression Omnibus database were used as the training cohort, while samples from The Cancer Genome Atlas database were used as the validation cohort. A metabolic gene signature was established to investigate a robust risk stratification for colon cancer. Subsequently, a prognostic nomogram was established combining the metabolism-related risk score and clinicopathological characteristics of patients. A total of 351 differentially expressed metabolism-related genes were identified in colon cancer. After univariate analysis and least absolute shrinkage and selection operator-penalized regression analysis, an eight-gene metabolic signature (MTR, NANS, HADH, IMPA2, AGPAT1, GGT5, CYP2J2, and ASL) was identified to classify patients into high- and low-risk groups. High-risk patients had significantly shorter overall survival than low-risk patients in both the training and validation cohorts. A high-risk score was positively correlated with proximal colon cancer (P = 0.012), BRAF mutation (P = 0.049), and advanced stage (P = 0.027). We established a prognostic nomogram based on metabolism-related gene risk score and clinicopathologic factors. The areas under the curve and calibration curves indicated that the established nomogram showed a good accuracy of prediction. We have established a novel metabolic gene signature that could predict overall survival in colon cancer patients and serve as a biomarker for colon cancer.
