Objective To investigate the association of neural differentiation factor 1 (NeuroD1) Ala45Thr polymorphism with type 2 diabetes by meta-analysis.Methods The electronic databases were retrieved from PubMed,EMBASE,CNKI,VIP fulltext database,and Wanfang fulltext database.Literatures about the association of NeuroD1 Ala45Thr polymorphism with type 2 diabetes from 2004 to 2012 were searched.The selected studies from 2004 to 2012 were included to analyze data based on the published meta-analysis of the NeuroD1 (Ala45Thr) gene polymorphism and type 2 diabetes written by Kavvoura,et al.The odds ratio of NeuroD1 (Ala45Thr) genotype distributions in type 2 diabetic patients compared with healthy control were analyzed.Rev-Man 5.0 software was applied for investigating hereogeneity among individual studies and summarizing effects with proper statistical methods.Thirteen case control studies were enrolled.Results A total of 3 896 patients and 3 186 control subjects were enrolled for the study.The pooled ORs of Thr45Thr45/(Ala45Thr+ Ala45Ala45) genotype in type 2 diabetes mellitus and control groups were 3.16 (95％ CI0.99-10.11) in the subgroup of yellow race and 1.09(95％ CI0.90-1.32) in the subgroup of white race,with no statistically significant difference(P＞0.05).The pooled OR of G/A allele in type 2 diabetes mellitus and control groups was 0.85 (95 ％ CI 0.72-0.99)/1.18 (95％ CI 1.07-1.38),with statistically significant difference (Z =2.02,P =0.04).Conclusions The A allele of NeuroD1 (Ala45Thr) locus may be a risk factor for type 2 diabetes mellitus.

To study the status of diet and nutrition in Uyghur families with maturity onset diabetes of young (MODY).Four MODY families were composed of four generations of Uyghur with 50 members collected from Kashgar,Shanshan,and Ili regions of Xinjiang Uyghur Autonomous Region.A dietary survey with a semi-quantitative food frequency questionnaire was conducted.According to the sex and different intensities of physical activity,the nutrient intake was calculated by nutrition calculator software,and the results were compared with recommended nutrients intake(RNI).Cereals,livestock,and poultry meat,being the main food stuff in Uyghur MODY families,accounted for 54.11％ and 13.87％ of total energy respectively,while fruit,fish,and shrimps were seldom taken,and accounted for 0.41％ and 0.26％ of total energy respectively.Carbohydrate,protein,and fat accounted for 55.0％,16.7％,and 28.4％ of total energy intake respectively,within the scope of the RNI for diabetes suggested by both Chinese Diabetes Society and the American Diabetes Association.The total energy and all three major nutrients were excessively taken by subjects of different genders and different intensities physical activity from Uyghur MODY families in Xinjiang.Uyghur diets lead to excessive calorie intake in the Uyghur MODY family members.The Health education of Uyghur language and text should be strengthened,so as to improve the scientific dietary knowledge.
