  • Research on Occupational Health and Safety of Medical Staff Based on ISO
           45001

    • Abstract: This paper aims to discussion on the application of International Organization for Standardization (ISO) 45001 in hospitals. With the spread of COVID-19 globalization, the occupational health and safety problems of many medical staff have become international commonalities. There are a lot of articles talking about how to protect medical staff, including World Health Organization (WHO), however most of them are focus on the details, which lack of system methodology and standardized model. By analyzing the Occupational Health and Safety (OH&S) risks faced by medical staff during the COVID-19, the importance of International Organization for Standardization (ISO) 45001 application in hospital industry is put forward. Firstly, the paper adopt a theoretical foundation by which or through which hospital can better manage medical staff’s occupational health and safety risks and improve their overall performance. Secondly, this paper uses Plan-Do-Check-Act (PDCA) model to hospitals, which provides a framework for hospital to plan what they need to do. Thirdly, from the ISO 45001 perspectives to explore how to solve the current occupational health problems faced by medical staff and adopt relevant programs to protect occupational health and safety of medical staff, thus promoting the healthy and sustainable development of individuals and hospitals. Findings-ISO 45001 can plays an important role in the occupational health and safety of medical staff. It is of great and urgent to instruct hospitals how to scientifically and effectively identify hazards (COVID-19), evaluate their risks and take corresponding prevention and control measures. Therefore it can promote the health and well-being of medical staff. The occupational health and safety management of medical staff in hospitals is also a concrete manifestation of their active fulfillment of social responsibilities. Originality/value: This paper offers an standardized angle to address the risks of occupational health and safety of medical staff during the spread of COVID-19. As for the application of ISO 45001, this paper provides some suggestions based on china’s practice and experience, which through the angles of theoretical research methods include high level structure, Plan-Do-Check-Act (PDCA) model and man, machine, material, Method, Environment (4M1E) model.
       
  • Distribution Pattern of SN in Qinghai-Tibet Plateau and Its Relationship
           with Environmental Factors

    • Abstract: Studying the distribution pattern and driving mechanism of Soil Nitrogen (SN) in the agricultural areas of the Qinghai-Tibet Plateau is of certain significance for the rational use of N fertilizer, improving the quality of land use and protecting the environment. The SN content of cultivated soil in Qinghai-Tibet Plateau agricultural areas was analyzed by combining geographical and meteorological factors. It was found that the average Soil Total N (STN) in farmland was 2.4690 g/kg, which was the first class standard (>2.0 g/kg) of nutrient classification standard in the second national soil census. Horizontally, the areas with low N are mainly concentrated in the southwest of the Qinghai-Tibet Plateau and the high in the southeast and eastern regions of the Tibetan Plateau. From the vertical distribution pattern of 2000 m to 5000 m, it gradually decreases with the increase of altitude. The climatic factors affecting the STN are daily average temperature ≥ 10°C accumulated temperature > annual evaporation > daily average temperature ≥ 0°C accumulated temperature. The climatic factors that affect the Soil Available N (SAN) are daily average temperature ≥ 10°C accumulated temperature > daily average temperature ≥ 0°C accumulated temperature > annual evaporation> annual sunshine hours> monthly average maximum temperature > annual precipitation amount.
       
  • Effect of Ultra-High Pressure Technology on Isomerization and Antioxidant
           Activity of Lycopene in Solanum Lycopersicum

    • Abstract: To evaluate the influence of the Ultra-High Pressure processing (UHP) on the isomerization and antioxidant activity of lycopene in tomatoes (Solanum lycopersicum), High Performance Liquid Chromatography (HPLC) and Ultraviolet-Visible Spectroscopy (UV-Vis) were used to separate and identify the isomer of lycopene. The scavenging activities against DPPH'and'OH present samples with and without UHP treatment were tested with ascorbic acid as positive control. Full wavelength scanning figure showed that a characteristic absorption peak was created at 361 nm, which was caused by trans-lycopene isomerizing into cis isomer. HPLC analysis found that five peaks (Rt = 19.082, 13.307, 9.790, 8.123, 7.207 min) were produced after UHP treatment, which were further identified by UV-Vis and four peaks among them showed a strong absorption peak at 361 nm which was in accordance with the UV-Vis spectroscopy of cis-lycopene. The total antioxidant, capable of scavenging hydroxyl radicals·OH and DPPH·radical of lycopene treated by UHP, were all higher than that of control and lycopene without UHP treated. Taken together, UHP treatment played the role in cis-trans conversion of lycopene and could also improve the antioxidant activity of lycopene oleoresin with a dose-dependent fashion.
       
  • Study on the Suitable Irrigation Amount of Microporous Membrane
           Water-Fertilizer Integration of Tomato in Spring in Plastic Greenhouse

    • Abstract: Water-saving irrigation is an important measure to alleviate the shortage of water resources in China. In this study, the growth, nutrient distribution, quality and yield of Tomato under different irrigation treatments are studied by using microporous membrane water-fertilizer integrated technology and the optimal irrigation water quantity under the condition of microporous membrane water-fertilizer integration was determined. The results show that the stem diameter and the fresh and dry weight of tomato increased under the treatment of microporous membrane irrigation, among which the irrigation of 84 m3.667 m-2 was the best, comparing with the traditional flooding irrigation. Microporous membrane irrigation promotes the accumulation of N, P and K in tomato plants. The organic acid content of tomato fruit was the highest under the treatment of 108 m3.667 m-2 and the lycopene content is the highest under the treatment of 96 m3.667 m-2. However, soluble protein, soluble solids, VC content and sugar acid ratio are the highest under the treatment of 84 m3.667 m-2 and the yield and water use efficiency of tomato are the highest under this treatment. Generally, the optimal irrigation amount of tomato under the condition of microporous membrane water-fertilizer integration is 84 m3.667 m-2. The experiment clarifies the crop water demand characteristics and provides a certain theoretical basis for the application of water-saving irrigation technology and high-yield cultivation.
       
  • Clinical Significance of Precise Hyperthermic Intraperitoneal Chemotherapy
           Up-regulation RP11-356I2.2 Restraining the Occurrence and Development of
           Gastric Cancer

    • Abstract: In order to study the therapeutic effect and possible mechanism of Precise Hyperthermic Intraperitoneal Chemotherapy (HIPEC) on gastric cancer, the expression of RP11-356I2.2 in gastric cancer cell lines and tissues was detected by real-time fluorescence quantitative PCR (RT-PCR). Chi-square test was used to analyze the correlation between the expression and clinic pathological parameters. Western blotting was used to detect the expression of RP11-356I2.2 and tumor suppressor geneKLF17 after precise HIPEC. The effect of RP11-356I2.2 on KLF17 protein was observed and expressed by Western blotting and immunofluorescence. COX regression model was used to analyze the relationship between the expression of RP11-356I2.2 and KLF17 and the prognosis of patients with gastric cancer. The results of RT-PCR showed that RP11-356I2.2 was lower in BGC-823, MKN-28, MGC-803, SGC-7901 and MKN-45 than normal stomach cells GES-1 (P<0.05). Its expression level was inversely proportional to the malignant degree of gastric cancer. Meanwhile, stable expression SGC-7901/RP11-356I2.2 cell line was established, western blotting and immunofluorescence showed the up-regulation of KLF17 protein. The expression of RP11-356I2.2 and tumor suppressor gene KLF17 increased after precise HIPEC. After 5 years of follow-up, the Disease-Survival rate (DFS) and total Survival rate (OS) of KLF17 high expression group were 9.7 and 14.2 months respectively, which were significantly longer (P<0.05) than KLF17 low expression group, DFS (5.4 months) and OS (10.2 months). The up-regulation of KLF17 protein by up-regulation of RP11-356I2.2 in precise intraperitoneal hyperthermic chemotherapy may be one of the mechanisms of HIPEC inhibiting gastric cancer.
       
  • Detection of Commercial Fraud in Processed Meat Products Using Rapid
           Techniques

    • Abstract: Meat adulteration with different species has become a considerable problem worldwide. It means that meat products contain undeclared meat species; so, the meat ingredients are not consistent with the label. It has direct impact on public health, religious faith, fair-trades and food safety standers. This study focused on species adulteration detection in meat products by applying accurate, slandered and fast techniques. Polymerase Chain Reaction (PCR) technique and Raw Meat FlowThroughTM Test were performed as fast techniques. Thirty samples of beef meat products (10 each of hawawshi, sausage and burger) were subjected to analysis by PCR technique using specific primers sets for equine, chicken and pig species on samples’ Deoxyribonucleic Acid (DNA). The adulteration rates with equine were 10%, 10% and 30% in hawawshi, sausage and beef burger samples, respectively. The adulteration rates with chicken were 80%, 50% and 100% in hawawshi, sausages and beef burger samples, respectively. While none of the examined samples was contaminated with pork. Results showed that 80% of all examined samples contained undeclared meat species. Out of the adulterated samples examined by PCR technique, eight samples were reanalyzed by the onsite Raw Meat FlowThroughTM Test which had taken only about 12 minutes to be performed. It was an on-site test for qualitative determination of species by visual inspection. The results confirmed those obtained by PCR technique by 100% in case of detection of poultry species. While in case of detection of adulteration by equine species, the FlowThroughTM Test gave negative results which indicated that it had the ability to detect horse specie only but could not detect other equine species as donkey and mule. This study suggests that these methods of detection can be applied by quality control laboratories and inspection services for fast and rapid determination of adulteration with poultry products in different meat products, but the FlowThroughTM Test is horse specific inside the equine species and this could be limitation to the test needs to improve it or beneficial points to differentiate between horse and donkey meat adulation combining with other methods.
       
  • MicroRNA-92a: The Administrator of Certain Diseases

    • Abstract: MicroRNA-92a (miR-92a) is an evolutionarily conserved noncoding small RNA that can regulate gene expression after transcription. Previous studies have found that miR-92a is overexpressed in many tumors and can regulate numerous tumor suppressor genes negatively, with relevant effects on the development of different tumors, by regulating the DUSP10/c-Jun N-terminal kinase (JNK), phosphatase and tensin homologs (PTEN)/AKT, Wnt and EP4/Notch1 signaling axes. MiR-92a also promotes the proliferation and migration of vascular smooth muscle cells (VSMCs) through the Rho-associated coiled-coil-forming kinase/myosin light chain kinase signaling pathway and inhibits VSMC apoptosis through the MKK4/JNK signaling pathway. Moreover, miR-92a affects endothelial functions; mediates endothelial dysfunction in chronic kidney diseases; mediates THBS1 inhibition; promotes the migration, proliferation and angiogenesis of neighboring endothelial cells (ECs); mediates the Nrf2/KEAP1/ARE signaling pathway to regulate vascular endothelial aging; and is involved in immune responses to activate ECs. This review summarizes the potential role and pathogenic mechanism of the miR-92a gene in certain diseases to provide possible new treatment options.
       
  • Adsorption and Descaling of Cellucotton and Chitosan-Modified Bentonite
           for Produced Water

    • Abstract: The compatibility of non-identical layers within the water present in the produced oil is poor and ion reactions in the oil mixed with water result in scale formation, thereby having a significant impact on oilfield safety production. In this study, methods for the descaling of produced water from different blocks were studied according to the quality characteristics of the produced water. Results show that scale was produced at a concentration of 94 mg/L when three-phase separated water and formation water were mixed at a volume ratio of 1:0.3. The flocculation performance was optimized when the pH of the mixed water sample was adjusted to 7.5 and addition amount of polyaluminium chloride and polyacrylamide was 80 and 3 mg/L, respectively. In addition, the mixed water sample was adsorbed and descaled using cellucotton and chitosan-modified bentonite. Results show that the method for treating the mixed water sample first with cellucotton followed by the chitosan-modified bentonite shows the optimal adsorption–flocculation performance, thereby reducing the concentration of scale in the treated water to 3 mg/L.

  • cDNA Cloning and Characterization of the House Dust Mite Allergen Sui p 2

    • Abstract: Suidasia pontifica (Sp) is a House Dust Mite (HDM) species found in tropical urban residential areas which causes sensitization of up to 75% of allergic patients. Cloning of allergens from Sp is a significant initial step in understanding the clinical significance of this HDM species. The study describes the cloning and in silico characterization of the group 2 allergen gene from Sp (Sui p 2) with significant homology to Myeloid Differentiation 2 (MD-2) lipid-binding (ML domain) protein allergens. Sui p 2 gene was amplified by Reverse Transcription – PCR using gene-specific primers designed from known HDM group 2 allergens. The amplicons were characterized using NCBI BLAST, ExPASy, MEGA7 and Chimera. Sui p 2 cDNA gene exhibits percent identity to Tyrophagus putrescentiae (65.84%), Aleuroglyphus ovatus (65.69%) and Blomia tropicalis (62.98%). Sui p 2 gene contains 405 bp open reading frame with untranslated regions on its 5’ and 3’ end. Furthermore, structure-based percent identity of Sui p 2 to the group 2 allergen of D. farinae and D. pteronyssinus is 47.62% and 46.83%, respectively. Predicted protein structure reveals a putative immunoglobulin fold consisting of preserved cysteine residues, hydrophobic core and two antiparallel β-sheets containing several TLR4, LPS and IgE binding sites. The results suggest that Sui p 2 may play an important role in HDM induced allergy and may be involved in the induction of the innate immune system. Characterization of Sui p 2 is important to evaluate properly its use for allergy component resolved diagnosis and allergen-specific immunotherapy.
       
  • Inhibitory Effect of Crude Walnut Leaf Polysaccharides on Oxidative Damage
           of Proteins and Proliferation of SGC-7901 Cells

    • Abstract: In this paper, we studied the inhibitory effect of crude Walnut Leaf Polysaccharides (WLP) on free radical-induced oxidative damage of proteins and anti-proliferation activity on human Gastric Cancer cells (SGC-7901). The oxidative degradation of Bovine Serum Albumin (BSA), mouse brain proteins (MBP) and Mouse Liver Proteins (MLP) induced by hydroxyl radical and alcoxyl radical was analyzed by Sodium Dodecyl Sulfate-Polyacrylamide Gel Electrophoresis (SDS-PAGE). In addition, MTT method was used to analyze the effect of WLP on cell viabilities of SGC-7901 cells. The results indicated that WLP significantly inhibited the oxidative damage of BSA induced by hydroxyl radical within the concentration range of 0.5~20 mg/mL. Similar protective effects were found in hydroxyl radical-induced oxidative damage on mouse tissue proteins. WLP inhibited the oxidative damage of three protein models induced by alcoxyl radical in a dose-dependent manner. Furthermore, WLP inhibited the growth of SGC-7901 cells in time- and concentration-dependent manner. In conclusion, WLP show significant inhibitory effect on protein oxidative damage induced by hydroxyl radical and alcoxyl radical as well as anti-proliferation capacity on SGC-7901 cells.

After diagnosis surgery followed by immunotherapy and/or chemo- radiation therapy are the available treatments. These treatments do not provide protection against disease progression or recurrence thus highlighting the need to identify and develop drugs that are capable of inhibiting bladder cancer. T24 cell line (human bladder transitional cell carcinoma) was treated with NEMO Binding Domain (NBD) peptide and tested for its cytotoxicity, cell cycle inhibition, apoptosis and migration, in vitro. The cytotoxicity of NBD peptide was tested on non-cancerous cells (NIH-3T3-L1, CHO, Vero) and the peptide localization in T24 cells was confirmed using confocal microscopy. The effects of NBD peptide and the standard drugs (cisplatin, gemcitabine) were compared with untreated control. Peptide based chemotherapy for human bladder cells was tested that include combinations of NBD and standard drugs. Statistical significance was assessed between the different treatment groups. The viability of T24 cells after NBD peptide treatment was reduced to 50% at a dose of 18.5 µM after 48 h. The NBD peptide elicited selective cytotoxicity dose-dependently in T24 cells while being non-toxic on normal (non-cancer) cell lines. Sub G0-G1 accumulation of T24 cells was seen where they underwent necrosis and lost the ability to migrate when treated with 100 µM NBD. T24 cell death increased to ~78% when treated with a combination of NBD with cisplatin and gemcitabine (standard drugs) as opposed to ~50% when treated with NBD peptide alone. NBD peptide exhibits specific anti-cancer activity on T24 cells in vitro and found to be non-cytotoxic to select normal cell lines. Combining NBD with standard drugs demonstrated excellent inhibition of malignant growth than the individual anti-neoplastic agents.
       
  • Detection of Soil Total Nitrogen, Phosphorus and Potassium Content Based
           on the Spectral Information of Citrus Canopy

    • Abstract: The content of total nitrogen, phosphorus and potassium in the soil is an important basis for calculating the best fertilization amount and realizing the reasonable fertilization of the orange planting soil in time and accurately. In this research, hyper-spectral technology is applied to detect the three soil nutrient elements in the cultivated soil of citrus trees. Four spectral bands with central wavelengths of 660, 780, 870 and 970 nm and width of 20 nm are selected to measure the spectral reflectance of the potted kumquats canopy by hand-held spectrometer. At the same time, the content of total nitrogen, phosphorus and potassium in the cultivated soil of kumquat is determined using traditional methods. The correlation between the spectral information of kumquat canopy and the content of soil nutrient elements is analyzed by correlation coefficient method. The prediction model of soil nutrient element content based on the spectral information is established by multiple linear regression method. The results showed that the total potassium content of soil is significantly correlated with the spectral reflectance at 660 nm wave band and significantly correlated with the spectral indexes of R660/R780, R660/R870 and R660/R970. R2 of the prediction model of total potassium content established on the basis of spectral reflectance and ratio spectral index of the selected band is 0.756 and 0.857 respectively, which shows good prediction effect of the model. There is no significant correlation between the spectral reflectance and ratio spectral index of the selected band towards the total soil nitrogen and phosphorus content and it cannot be used for the rapid measurement of total nitrogen and phosphorus content. Further study is needed to select suitable spectral band and spectral index.

  • Effects of Potassium Fulvic Acid and DA-6 on the Growth and Yield of
           Tomato Cultivated with Rock Wool

    • Abstract: Potassium fulvic acid and diethyl aminoethyl hexanoate (DA-6) are two kinds of growth regulators with yield increasing and quality improving. There are few reports on the effects of adding potassium fulvic acid and DA-6 in nutrient solution on the growth of soilless culture of vegetables. In this study, tomato was used as the test material to add different concentrations of potassium fulvic acid (0, 15, 30 mg•L-1) and DA-6 (0, 2.5, 5 mg•L-1) into nutrient solution of total nutrient minerals, so as to study the effects of adding two growth-regulating substances to nutrient solution of total nutrient mineral on the growth, yield and quality of tomato in soilless cultivation with rock wool in solar greenhouse. The results showed that: With no addition of potassium fulvic acid and DA-6 as the control, in the early stage of bearing fruit, the potassium fulvic acid added with 30 mg•L-1 nutrient solution alone had an inhibitory effect on tomato plant height and the inhibition could be alleviated by adding DA-6. When 30 mg•L-1 potassium fulvic acid and DA-6 were added together, the fresh quality of single stem and dry quality of single leaf in the early and middle stage of tomato bearing fruit were significantly improved. 15 mg•L-1 potassium fulvic acid and 2.5 mg•L-1 DA-6 had the best effect on the total yield of a single plant, which was 21.77% higher than that of the control. 15 mg•L-1 potassium fulvic acid and DA-6 could significantly increase the C content and sugar acid ratio of tomato fruit. To summarize, 15 mg•L-1 potassium fulvic acid and 2.5 mg•L-1 DA-6 showed synergistic effect, which has the best improvement effect on the growth, yield and quality of best.
       
  • An Effective and Viable DNA Extraction Protocol for FFPE Tissues and its
           Effect on Downstream Molecular Application

    • Abstract: Archival Formalin-Fixed Paraffin-Embedded (FFPE) tissues are a readily available source of DNA for retrospective studies including genetic predisposition. FFPE tissues present significant challenges for extraction of pure genomic DNA in adequate amounts due to the harsh fixation conditions and long-term storage associated with samples. The aim of the study is to propose a simple, in-expensive, viable protocol for the extraction of DNA from FFPE tissues and to optimize the same for the detection of 3’UTR miRNA binding site polymorphism in ADAMTS1 gene in colorectal cancer tissues and normal colonic mucosa archival tissues using Sanger sequencing and TaqMan SNP genotyping assay. Five different DNA extraction methods were compared and analyzed. NanoDrop quantification demonstrated that out of the various methods tested, highest quantity and pure DNA was obtained from Modified non heating extraction. When we further applied this method for colorectal cancer tissues and normal colonic mucosa archival tissues the NanoDrop readout indicated that the DNA was intact and pure. Intra samples comparison over a time period of 6 months revealed that the DNA was intact. The samples isolated with Modified non heating extraction were found suitable for downstream processes such as Sanger sequencing and TaqMan SNP genotyping assay. This cost effective and non-arduous protocol can successfully extract even minute quantities of DNA from FFPE tissues and facilitate the downstream molecular analysis of a large number of archival specimens for retrospective studies.
       
  • Improved SDA Production in High Lipid Accumulating Strain of Mucor
           circinelloides WJ11 by Genetic Modification

    • Abstract: Stearidonic Acid (SDA; 18:4, n-3) is a ω-3 polyunsaturated fatty acid which is nutritionally important and has pharmaceutical applications. Hence, scientists are trying to construct SDA producing oleaginous microorganisms by genetic modification. Two enzymes, Delta-6 Desaturase (D6D) and ω-3 desaturase catalyze the reactions to produce SDA from Linoleic Acid (LA; 18:2, n-6). But the key enzyme, ω-3 desaturase converts LA to ALA and GLA to SDA is absent in high lipid accumulating Mucor circinelloides WJ11, retarding its ability to produce SDA. Therefore, in this study, we overexpressed fad3 gene from Arabidopsis thaliana in M. circinelloides WJ11 to produce SDA. Overexpression of fad3 gene in M. circinelloides WJ11 resulted in the production of 340 mg/l SDA. This research opened a new opportunity to make use of this fungus for industrial production of SDA.
       
  • Effect of Novel Engineered Aspergillus oryzae on Soybean Meal Fermentation
           and Optimization of Cultivation Conditions

    • Abstract: The filamentous fungus Aspergillus oryzae is an important strain in fermentation industry. In this study, to test the possibilities of improving polypeptides production, the soybean meal fermentation products were used to investigate the efficiencies of four different novel recombinant engineered A. oryzae strains A. oryzae subC, A. oryzae asp, A. oryzae Ap and A. oryzae pep. Gel filtration was employed to separate the products produced by the four engineered strains and wild-type A. oryzae and the antioxidant activities of each component of the products were compared. The results showed that the proportion of small-molecule peptides produced by A. oryzae pep fermentation was higher, mainly in the range of 1000-2000 Da, when compared with that yielded by wild-type A. oryzae fermentation. The antioxidant activities of the different components of the fermentation products produced by various engineered strains, especially component I of A. oryzae pep, showed varying degrees of improvement on DPPH and ·OH free radical scavenging activities, reaching 73.1%±0.9% and 81.4%±1.2%, respectively. To further enhance the fermentation performance of A. oryzae pep, response surface methodology was used to optimize the fermentation conditions. The results indicated that the polypeptide conversion rate reached 40.4% following fermentation with 8% inoculum for 108 h at 31°C. These findings are significant for the development of A. oryzae strains and high-value utilization of soybean meal resources.
       
  • Optimization of Ultrasonic/Microwave Assisted Extraction (UMAE) and
           Rheological Properties of Polysaccharides from Auricularia polytricha

    • Abstract: Polysaccharides from Auricularia polytricha (APPS) were extracted using Ultrasonic/Microwave Assisted Extraction (UMAE) technology. UMAE conditions of APPS were optimized with Response Surface Methodology (RSM). Rheological properties of APPS were investigated. The results suggested that the optimal UMAE conditions for APPS were ratio of water to raw material 22 (mL/g), extraction time 15.3 min and microwave power 59W. APPS solution exhibited Newtonian flow behavior at low concentration, formed entanglement network at lower concentration and established weak gel structures with solid-like properties at higher concentration. The viscosity of APPS solutions decreased when temperature increased. The viscosity, storage (G') and loss (G") modulus of APPS solution increased when sucrose concentration increased. Heating time and freeze-thaw changes had no significant effect on rheological properties of APPS. The results suggested that UMAE was a suitable and efficient method for APPS extraction and APPS had potential as a novel food additive hydrocolloid in food industry.
       
  • ECG Energy Change Study Based on Variational Mode Decomposition

    • Abstract: Variational Mode Decomposition (VMD) decomposes the signal into a series of Intrinsic Mode Type Functions (IMTFs) according with variational model and fluctuating characteristics of the signal itself, thus very suitable for the analysis of nonlinear and non-stationary Electrocardiogram (ECG) signal. Energy of ECG signal has certain distribution rules, but which could be affected by diseases; therefore, the study of ECG energy distribution change is of great importance to the research and clinical diagnosis of heart diseases. In this paper, firstly, ECG signals are decomposed into a series IMTFs with VMD and the fluctuating characteristics and physical meanings of ECG signals on different time scale are analyzed by observing the fluctuation rule of IMTFs. Then, the energy vectors of ECG signals are obtained by calculating the energy of each IMTF and a comparative analysis of energy vectors is conducted between healthy people and three kinds of heart disease patients. It can be seen according to the experimental results that heart disease could cause high-frequency components of the VMD energy vector to drop significantly and the VMD energy vector can well reflect the impacts of age and disease on ECG energy distribution, which can be used as a reference for heart disease diagnosis.
       
  • Calcium-sorbitol Chelating Technology and Application in Potatoes

    • Abstract: Researches on low-molecular organic compounds are concentrated in amino acid and Humic acid chelating fertilizer, but few in sorbitol chelated calcium. In this study, selecting sorbitol as chelating agent, the technological conditions of chelating sorbitol with calcium and the effect of sorbitol chelated calcium on potato were studied. The impact factors on the stability of the fertilizer were investigated, including sorbitol dosage, pH value, chelating time and temperature. Then a field experiment was conducted on potato. Three treatments included water sprayed as a control, calcium nitrate and sorbitol chelated calcium sprayed. Each treatment had three replicates. The results showed that by orthogonal experiments, the sorbitol dosage has the greatest influence on the stability of the chelating system. The optimum conditions for the synthesis were determined as follows: The sorbitol dosage of 12 g, the chelating temperature of 50°C, the pH of 4 and the chelating time of 45 min. Compared with those of potatoes fertilized with inorganic calcium nitrate, the yield of potatoes sprayed with sorbitol chelated calcium increased by 14.23% and their marketable tuber percentage increased by 3.58%; the nitrate nitrogen content in potatoes decreased by 11.89%; the accumulation of phosphorus and potassium in potato tubers increased. Generally, the application effect of our prepared sorbitol chelated calcium on potato was remarkable.
       
  • Study on Carbon Source Screening Technology for Prevention and Control of
           Banana Fusarium Wilt

    • Abstract: With the spread of banana Fusarium wilt and the aggravation of the damage, it has become the biggest threat to the banana industry. Many studies have shown that bio-organic fertilizer plays an important role in the prevention and control of banana wilt, but most studies focused on biocontrol bacterium screening, not screening carbon sources that could prevent banana wilt, which lead to organic fertilizer fertilization without better effect. So that, a pot culture experiment (I) with inoculating Fusarium oxysporum f. sp. Cubense (FOC) on bananas was carried out to screen the carbon sources, and d-malic acid (CS2) to prevent and control banana wilt had been screened out by Biolog technology and Principal Component Analysis of microbial community level physiological profiling. To verify application effects of CS2, another banana pot experiment (II) with FOC inoculation had been done. The results showed that: (1) CS2 can effectively improve the activity of soil microorganisms. (2) CS2 can significantly reduce FOC population in soil, and the FOC population treated with CS2 was respectively lower than that treated with control carbon source (CS1) and without carbon source (CK1) 48% and 59%. (3) The banana wilt infection rate and disease index of CS2 treatment were significantly smaller than those of CS1 and CK1. (4) CS2 can promote the growth and biomass accumulation of bananas in pathogenic soil. In conclusion, the screening technology studied here can be applied to screen out the carbon sources for prevention of banana Fusarium wilt, which has great significance to the improvement of prevention effect of biological organic fertilizers to banana wilt.
       
  • Effects of Oak Chip Treatments on Quality of Dry White Wines During Aging

    • Abstract: The objective of the research was to evaluate the effect of different oak chip treatments on quality of Longyan dry white wine during aging. Phenolic substances, antioxidant activity and Cu2+ reduction force were measured. The results showed that wines treated with French oak chips (6 g/L) had significantly higher contents of total phenols (0.083 mg/mL) and flavonoids (0.063 mg/mL), also the highest total antioxidant capacity (47.853 U/mL) was observed. However the scavenging rate of DPPH free radicals and hydroxyl radical scavenging rate were the highest in samples aged with American oak chips (6 g/L) and Yanshan oak chips (2 g/L), respectively. As for 12 monomer phenols determined by high-performance liquid chromatography, French oak chips can contribute to the formation of monomer phenols, especially the generation of syringaldehyde (15.134 mg/L) and guaiacol (17.345 mg/L). Cu2+ reduction ability of wine sample increased with the increase of oak chips content. Correlation analysis revealed that the monomer phenols had a strong correlation with total antioxidant capacity, DPPH radical scavenging rate and hydroxyl radical scavenging rate. Understanding the influence of oak chips on wine properties could aid to lay a theoretical foundation for the effective use of oak chips in wine.

  • Total Phenolic, Resveratrol Content, Antioxidant and Antimicrobial
           Activity in Five Cultivars of Peanut Sprouts

    • Abstract: Peanut sprout is one of the potential natural sources of bioactive substances. In this study, five different peanut cultivars were conducted to germination, the change in total phenolic compounds, resveratrol content, antioxidant and antimicrobial activity were investigated. The sprouts of five peanut cultivars (Fuhua, Silihong, Dabaisha, Xiaobaisha and Huayu) were extracted using 75% ethanol for 3 h and the crude extracts were collected. When the five peanut kernels were germinated at 25°C for 5 days, the total phenolic compounds increased significantly from range of 0.55 to 0.96 (μg Gallic acid/g) up to the range of 1.97 to 2.44 (μg Gallic acid/g) and the resveratrol contents showed similar trend, from range of 8.94 to 15.62 μg/g up to the range of 31.74 to 46.49 μg/g depending upon peanut cultivar. Among the five cultivars, Xiaobaisha showed the highest phenolic content [2.44 (μg Gallic acid/g)], expressed the highest 2,2-diphenyl-1-picrylhydrazyl scavenging value [(84.86±4.02) mmol/L TE/g dry weight] and ferric ion reducing antioxidant power scavenging value [(92.98±3.71) mmol/L TE/g dry weight] on the fifth day. In the antimicrobial evaluation the five sprout extracts were highly effective in inhibitory zone assay followed by Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) analysis against five pathogen microbial. In comparison with other peanut cultivars, the inhibitory effects were strongest in Silihong, the average MIC and MBC values against 5 spoilage bacteria were 10.66 and 28.52 mg/mL, respectively. In summary, this work provides evidences that Xiaobaisha and Silihong might be applied as antioxidant and antibacterial agent in food and pharmaceutical industries.
