中国营养学会第十五届全国营养科学大会

作者： yanan ma Ming Sun Jiajin Hu Yang Yu Yang Liu Deliang Wen Department of Biostatistics and Epidemiology School of Public Health China Medical University Health Sciences Institute China Medical University

Metabolic syndrome(MetS) is a growing public health concern, which is a complex metabolic disorder consisting of abdominal obesity, hypertension, hyperglycemia, and dyslipidemia. MetS could trigger many adverse conditions, such as diabetes, cardiovascular disease, and even cancers. Adverse lifestyle, socio-economic status, diet, and other environmental factors are associated with the risk of MetS. Diet is one of the modifiable risk factors for MetS, and evidence from Chinese populations is limited and inconsistent. The purpose of this investigation was to identify the main dietary patterns and to explore the different relationships between these patterns and MetS in Han and Mongolian populations in China. Methods This is a cross-sectional survey based on residents in Fuxin city, Liaoning Province, China, in 2021. A total of 2,758 participants with a semiquantitative food frequency questionnaire(FFQ) were eventually included in this study after further data screening. The FFQ consisted of 24 food items, including nine frequency categories ranging from "almost never eat" to "three times or more per day". Participants reported their food intake frequency over the past year. We identified dietary patterns using principal components analysis. Orthogonal rotations using Kaiser s criterion(eigenvalues>1.3) were utilized to establish the number of factors. Only the absolute values of factor loading >0.20 were included in the analysis, as these items represented the foods with the strongest relationships to the identified factors. The dietary patterns were named according to the magnitude of the factor scores and the interpretability of the overall diet. MetS was defined by the Guidelines for the Prevention and Treatment of Type 2 Diabetes in China(2020 Edition). Multivariable logistic regression analysis was used to compare the odds ratios(ORs) and 95%CI to analyze the relationship between dietary patterns and MetS. All participants provided written informed consent, and th

In conclusion,33. 5% of Copper quinolate SC,25% of Bromothalonil EC,70% of mancozeb WP and 400 g/L of Flusilazole EC achieved the best inhibitory effect both in mycelial growth and spore germination,which could be used as the preference fungicides for the control of persimmon anthracnose,and 70% of Polyram WG and 50% of Triram WP achieved the secondly best inhibitory effect,which could be used as alternative fungicides. The results of this research could provide scientific evidence for the effective control of persimmon anthracnose,and more optional pesticides for utilization in the production practice of persimmon industry.

应用生物信息学数据挖掘探究胱硫醚β-合成酶和胱硫醚γ-裂解酶基因表达在肝癌不良预后中的预测价值

中华肝脏病杂志 2023年第11期31卷 1169-1175页

作者：刘子衿马亚楠首都医科大学宣武医院消化内科北京100053 首都医科大学附属北京佑安医院肝病消化科北京100069

目的探究肝癌和胱硫醚β-合成酶(cystathionineβ-synthase,CBS)基因及胱硫醚γ-裂解酶(cystathionine-γ-lyase,CTH)基因的关系。方法通过挖掘GEO(gene expression omnibus)与TCGA(the cancer genome atlas)数据库,对肝癌的临床特征与CBS及CTH基因表达进行了相关性分析。并通过对肝癌细胞系进行免疫印迹验证。结果CBS及CTH在肿瘤中的表达较非肿瘤明显降低(P<0.05)。Cox回归结果显示CBS是肝细胞癌不良预后的独立危险因素(HR=0.65,P=0.02)。针对CBS基因对不同肿瘤分期进行单因素logistics回归分析,发现肝癌TNM分期II期比I期(P=0.01,OR=0.50)、III期比I期(P=0.03,OR=0.56)、T分期T2期比T1期(P<0.01,OR=0.43)、T3期比T1期(P=0.02,OR=0.54)CBS基因显著降低。肝癌TNM分期III期比I期(P=0.01,OR=0.50),Edmondson分期II期比I期(P=0.03,OR=0.48),III期比I期(P<0.01,OR=0.30),IV期比I期(P=0.03,OR=0.22)CTH基因表达显著降低。GSEA富集分析结果显示,与肝癌细胞CTH与CBS基因表达相关性最高的信号通路为细胞色素P450(FDR Q<0.01,FWER P<0.01)。免疫印迹结果显示,与人肝永生化细胞系HL-7702相比,HLE和Hep3B细胞等肝细胞癌细胞系中CTH下游蛋白CSE表达降低。结论肿瘤组织中的CBS及CTH基因表达低于正常组织。CBS基因是肝细胞癌不良预后的独立危险因素。与CBS及CTH基因关系最为密切的是信号通路为细胞色素P450通路。
