In this study, the fatty acid desaturase gene FAD2 was cloned from Coix lacryma-jobi L. and its molecular structure and function were studied. The results showed that the full-length cDNA sequence of FAD2 gene was 936 bp encoding 311 amino acid residues. Bioinformatics prediction results showed that the protein encoded by the FAD2 gene was an alkaline hydrophilic unstable protein with a molecular weight of 34.87 kDa. It contained three transmembrane helix domain, and did not contain the signal peptide splicing site, and was most likely to be located in plasmid membrane. Compared with other similar genes in plants, it has only a histidine conserved site, His Box Ⅲ histidine site (HXXHH), suggesting its activity may be reduced. Phylogenetic tree analysis showed that FAD2 was closely related to monocotyledonous plants, especially Maize and Oryza sativa japonica Group, but farther from dicotyledonous plants. Therefore, it was inferred that FAD2 might have similar functions with similar genes in Maize and Oryza sativa japonica Group. In addition, the expression of FAD2 gene could be detected in Coix lacryma-jobi L. with high oil content, but not in low oil content of Coix lacryma-jobi L. In order to clarify the function of FAD2, the gene was heterologously expressed in sporomyces cerevisiae. The results showed that the protein encoded by FAD2 gene did not catalyze the formation of C18∶1 unsaturated fatty acid into C18∶2 unsaturated fatty acid. Therefore, it was speculated that the deletion of histidinine conserved site of FAD2 gene might lead to the decrease of protein activity or even inactivation. This study provides reference value for further understanding the molecular structure characteristics of fatty acid desaturase. At the same time, it laid a foundation for elucidating the biosynthetic pathway of Coix lacryma-jobi L.

Objective:To identify age and gender standardized body mass index among children and adolescents and explore their associations with high blood pressure (HBP) in late adolescence.Methods:The current study was based on the Health Promotion Program for Children and Adolescents, school-based surveillance successively conducted from 2012 to 2019 in Suzhou, China. A total of 11 812 children and adolescents aged 16-18 years, who had ≥4 examination records during 2012-2018 and were also involved in a surveillance program in 2019, were included. Latent class growth mixture modeling was used to identify the BMI-Z trajectories in different genders, and multivariate logistic regression was used to analyze the associations between different BMI-Z trajectories and risk of HBP in late adolescence.Results:Six distinct BMI-Z trajectories were determined for both genders:thin, slightly thin,standard, declining, overweight, and obese. Compared with the regular group, the obesity group had 94.0% ( OR=1.94, 95% CI: 1.43-2.63) and 107.0% ( OR=2.07, 95% CI: 1.33-3.22) increased risk of developing HBP in late adolescence in boys and girls, respectively. However, a neutral association was found between the descending group and HBP in late adolescence. Conclusions:Persistent obesity in children may increase the risk of HBP in their late adolescence. If an obese child restores normal weight before late adolescence, the risk of HBP may reduce.

Gut injury continues to be the devastating and unpredictable critical illness associated with increased cell death of intestinal epithelial cells (IECs). The IECs, immune system and microbiome are the interrelated entities to maintain normal intestinal homeostasis and barrier integrity. In response to microbial invasion, IEC cell death occurs to maintain intestinal epithelium function and retain the continuous renewal and tissue homeostasis. But the imbalance of IEC cell death results in increased intestinal permeability and barrier dysfunction that leads to several acute and chronic intestinal diseases, such as intestinal ischemia/reperfusion (I/R), sepsis, inflammatory bowel diseases (IBD), necrotizing enterocolitis (NEC), etc. During the pathophysiological state, the excessive IEC apoptotic cell death leads to a chronic inflammatory condition, later switches to necroptotic cell death mechanism that induces more pathological features than apoptosis and may also induce other lytic cell death mechanisms like pyroptosis and ferroptosis to increase the pathogenesis of the intestinal diseases. But still, there remains gaps in the fundamental knowledge about the IEC cell death mechanisms in chronic intestinal diseases. Together, a deep understanding of the specific cell death mechanisms underlying chronic intestinal diseases, including sepsis, IBD, NEC, and intestinal I/R, is desperately needed to develop emerging novel promising therapeutic strategies. This review aims to show how the acute and critical illness in the gut are driven by IEC cell death mechanism, such as apoptosis, necrosis, necroptosis, pyroptosis, and ferroptosis.

Background: Few data are available regarding the progression of liver disease and therapeutic efficacy in chronic hepatitis B virus (HBV) carriers infected by mother-to-child transmission (MTCT). This study aimed to investigate these two aspects by comparing the adult chronic HBV carriers in MTCT group with those in horizontal transmission group. Methods: The 683 adult chronic HBV patients qualified for liver biopsy including 191 with MTCT and 492 with horizontal transmission entered the multi-center prospective study from October 2013 to May 2016. Biopsy results from 217 patients at baseline and 78 weeks post antiviral therapy were collected. Results: Patients infected by MTCT were more likely to have e antigen positive (68.6% vs. 58.2%, χ² = -2.491, P = 0.012) than those with horizontal transmission. However, in patients with MTCT, levels of alkaline phosphatase (ALP) (P = 0.031), Fibroscan (P = 0.013), N-terminal propeptide of Type III procollagen (PIIINP) (P = 0.014), and Laminin (LN) (P = 0.006) were high, in contrast to the patients with horizontal transmission for whom the levels of albumin (ALB) (P = 0.041), matrix metalloproteinase-3 (MMP-3) (P = 0.001) were high. The 47.2% of patients with MTCT and 36.8% of those with horizontal transmission had significant liver fibrosis (P = 0.013). Following antiviral therapy for 78 weeks, 21.2% and 38.0% patients with MTCT and horizontal transmission acquired hepatitis B e antigen (HBeAg) clearance, respectively (P = 0.043), and the virological response rates were 54.7% and 74.1% in the MTCT and horizontal groups, respectively (P = 0.005). MTCT was a risk factor for HBeAg clearance and virological response. Conclusion: Adult patients with MTCT were more prone to severe liver diseases, and the therapeutic efficacy was relatively poor, which underlined the importance of earlier, long-term treatment and interrupting perinatal transmission.

To introduce the application status of network Meta-analysis( NMA) in the field of traditional Chinese medicine,and to discuss the application value of NMA in the field of traditional Chinese medicine,this study comprehensively reviewed the systematic reviews with application of NMA in the field of traditional Chinese medicine. CNKI,Wan Fang,Sino Med,VIP,Embase,PubMed and Cochrane Library and the reference list of previous studies were searched. The AMSTAR scale was used to evaluate the quality of literature methodology,and PRISMA-NMA checklist was used to measure the degree of report specification. Overall,122 articles were included,including 80 in Chinese and 42 in English. The included studies centered on cancer,bone and joint disease,cardiovascular disease,respiratory disease,mental disease and digestive disease. Additionally,the intervention can be categorized into three groups,traditional Chinese medicine injection,oral Chinese medicine or prescription,and traditional physical therapy including acupuncture.Nearly one-third of the researches' intervention program is aimed at comparing the effect of Chinese and Western combined therapy and monotherapy. The overall methodology quality grade is medium and the report quality is average,with methodology reporting and result reporting especially need to be improved. The subgroup analysis shows that the methodology quality of the English literatures is evidently higher than Chinese literatures,and the quality of the literatures published after 2015 is higher than those published in or before 2015.This study indicates that the NMA can compare multiple treatments simultaneously,which accords with characteristics of the clinical practice in traditional Chinese medicine that is complex and individual. NMA in the field of traditional Chinese medicine is still in the process of development. With higher level of quality control and reporting as well as the improvement of the statistical methodology and the accumulation of original researches,NMA application in the field of traditional Chinese medicine will be promising.

OBJECTIVETo systematically evaluate the effectiveness and safety of Sodium Tanshinone II A Sulfonate Injection (STS) as one adjuvant therapy for treating unstable angina pectoris (UAP).

METHODSRandomized controlled trials (RCTs) of UAP treated by STS were searched in the China National Knowledge Infrastructure Database (CNKI), VIP Database for Chinese Technical Periodicals (VIP), Wanfang Database, the Chinese Biomedical Literature Database (CBM), Web of Science, the Cochrane Library, Embase, and PubMed, which from inception to January, 2016. The Cochrane Risk Assessment Tool was used to evaluate the methodological quality of the RCTs. The Review Manager 5.3 software was used to conduct the metaanalysis.

RESULTSThe results showed that 17 RCTs involving 1,372 patients were included. The meta-analysis indicated that the combined use of STS and Western medicine (WM) in the treatment of UAP can obviously improve the total effective rate [risk ratio (RR)=1.31, 95% confidence interval (CI) (1.24,1.39), P<0.0001], and the total effective rate of electrocardiogram [RR=1.43, 95% CI (1.30,1.56), P<0.0001], decrease the level of CRP [mean difference (MD)=-3.06, 95%CI (-3.85,-2.27), P<0.00001], fibrinogen [MD=-1.03, 95% CI (-1.16,-0.89), P<0.00001], and whole blood high shear viscosity [MD=-0.70, 95% CI (-0.92,-0.49), P<0.00001]. Additionally, the occurrence of adverse drug reaction of the experimental group was significantly higher than that of the control group [RR=3.57, 95% CI (1.28, 9.94), P<0.05].

CONCLUSIONSCompared with WM, the combined use of STS was more effective.

Objective To describe the social support and self-efficacy in patients with viral and hepatitis cirrhosis and to investigate the relevance of social support and self-efficacy.Methods By convenient sampling,totals of 105 patients were surveyed with social support scale,and chronic disease self-efficacy scale.Results Totals of 130 questionnaires were handed out and 105 effective questionnaires were recovered,with the rate of 80.77％.The score of social support of patients was (41.87 ± 7.47),and 61.0％ patients with moderate level,39.0％ patients with high level.Among them,subjective support score was (24.43 ± 4.08) with high level,objective support score was(10.45 ± 2.39) with low level,social support score was (6.99 ± 2.44)with moderate level.The self-efficacy score of patients was (48.53 ± 7.78).The scores of social support and its dimensions were markedly and positively correlated with self-efficacy and its dimensions and the value of correlation coefficients ranged from 0.601 to 0.835 (P ＜ 0.01).Conclusions The level of social support in patients with viral and hepatitis cirrhosis is moderate or high,with higher subjective social support level and lower objective social support level.In all the chronic diseases,the self-efficacy in the patients is in higher level.The score of social support is markedly and positively correlated with self-efficacy,the higher social support,the stronger self-efficacy.

The aim of the present study is to investigate the expression of a novel estrogen receptor, G protein-coupled receptor 30 (GPR30) and its correlation with matrix metalloproteinases-9 (MMP-9) in epithelial ovarian cancer (EOC). Ovary tissues were obtained from 39 female patients, including 30 cases of EOC and 9 cases of benign ovarian tumor. Four normal ovary tissues were used as control. Immunohistochemical staining was used to detect the expressions of GPR30 and MMP-9. Chi square test, Fisher's exact test and Spearman's rank correlation analysis were used for statistical analysis. The results showed that GPR30 overexpression rate in EOC cases was significantly higher than those in benign ovarian tumor and normal ovary cases. Whereas MMP-9 overexpression rate in EOC cases was significantly higher than that in normal ovary cases, without any difference to that in benign ovarian tumor cases. To demonstrate the relationship between GPR30 and clinicopathological variables of EOC, we further analyzed the pathology type, FIGO stage and age of patients sampled in our study. The analysis showed there were significant differences of GPR30 overexpression rate among various pathology types and different FIGO stages (P<0.05), and no significant difference of both GPR30 and MMP-9 among three age groups (P>0.05). Moreover, GPR30 expression was positively correlated with MMP-9 (r(s)=1.000, P=0.002). These results suggest that GPR30 may be involved in the invasion and metastasis of EOC, being a potential index of EOC early diagnosis and malignancy grade prediction.
