Both ?-cell dysfunction and insulin resistance contribute to the development of type 2 diabetes, and ?-cell function, especially early insulin secretion, is important in maintaining normal glucose tolerance. This review focuses on the ciritical role of ?-cell dysfunction in the pathogenesis of type 2 diabetes.

Objective To investigate the correlation of subtypes of the lymphocytes with metabolic syndrome in the aged.Methods 955 aged male and 150 aged female were recruited to a cross-sectional case-control study.CD3+,CD4,CD8+,CD19+,NK cell was measured with flow cytometry.ResultsCD3+,CD19+,NK cells showed no difference in cases and in controls.CD4+/CD8+ ratio declined in subjects with metabolic syndrome,and the ratio declined further with the more criteria.The analysis of multiple analysis regression showed that metabolic syndrome depressed CD4+/CD8+ ratio in the aged.Conclusion Metabolic syndrome was correlated with the disorder of immunity.

Objective To investigate the association between FcγRIIA H/H131 genotype and pneumonia through a comprehensive meta‐analysis .Methods Databases including PubMed ,Embase ,and China National Knowledge Infrastructure (CNKI) were searched with such terms as “FcgammaRIIa” ,“FCGR2A” ,“Fcgamma receptor IIA” ,“CD32” and“pneumonia” ,“polymorphism” ,“variant” ,“genotype” ,“allotype” ,as well as“pneumonia”and“polymorphism”in Chinese to identify relevant studies .Two reviewers independently extracted the data .Crude odds ratios (ORs) and corresponding 95%confidence intervals (CIs) were estimated .Heterogeneity across studies and publication bias were evaluated and sensitivity analyses were performed .Results Six case‐control studies were finally included in this analysis .The results indicated an association between FcγRIIA H/H131 genotype and pneumonia susceptibility (OR 1 .67 , 95% CI 1 .11‐2 .51 ) , but no significant association with R/R genotype(OR 1 .09 ,95% CI 0 .85‐1 .40) or H/R genotype(OR 0 .81 ,95% CI 0 .60‐1 .19) . Statistically significant heterogeneity was found during data pooling (I2 was 75 .4 % ,51 .8% and 71 .9% ) .Sensitivity analyses further indicated the reliability of the study .Egger′s and Begg′s tests identified publication bias in R/R genotype ,but not in H/H or H/R genotype .Conclusions We preliminarily find an association between FcγRIIA H/H131 genotype and pneumonia susceptibility .

Objective To investigate the situation of pre-pregnancy health check in rural areas of Sichuan province and get the key difficult points during the process of carrying out the work.Methods According to the economic situation in Sichuan province and geographic distribution,random eight areas in Sichuan province (Chengdu,Neijiang,Nanchong,Ziyang,Meishan,Zigong,Les-han and Suining),investigate pregnant women in maternal and child health care institutions and family planning service institutions at all all levels in the areas above.Results Only 334 people (33.26%)underwent the pre-pregnancy health check during the 974 pregnant women in rural areas.The rate of planned pregnancy is low;the rate of unintended pregnancy is close to 40.00%.55.29%of the planned pregnancy women didn′t undergo the pre-pregnancy health check.And the factors that affect their behavior of under-going pre-pregnancy health check are whether planned pregnancy and personal attitude towards pre-pregnancy health check.Conclu-sion The rate of pre-pregnancy health check is low in the pregnant women from rural areas of Sichuan province,the health sector needs to make efforts to promote and enhance the awareness of the rural pregnant women to prevent birth defects and the initiative in participation.

Objective To observe the co-expression plasmid of tissue plasminogen activator (tPA) and vascular endothelia growth factor165 (VEGF165) in vascular endothelial cell (VEC) and to study the effect of the product on the proliferation of VEC and fibrinolysis activity. Methods pBudCE4.1/tPA-VEGF165 was transfected into VECs by using lipofection. The expression of tPA and VEGF165 at mRNA level was detected by RT-PCR and expression at protein level was detected by Western blot. The fibrinolysis activity of VEC culture solution of transfecting tPA and VEGF165 genes were detected by fibrin plate technique. The VEC and VSMC were cultured with VEC culture solution of transforming tPA and VEGF165 genes, the proliferation of VEC and VSMC were evaluated with 3?H-TdR incorporation and flow cytometry (FCM). Results The expression of tPA and VEGF165 in the transfected VECs was detected. The fibrinolysis activity of transfected VEC culture solution was also detected. tPA and VEGF165 products in VECs elevated proliferation of VEC, while there was no effect on the proliferation of VSMC. Conclusion The tPA and VEGF165 eukaryotic co-expression plasmid could express in transfected VECs, and the expression products have biology activity.

AIM: To observe the effect of Jiawei sinisan (JWSNS) on some amino acids in hippocampus of rats with chronic stress. METHODS: Wistar rats were randomly divided into 3 groups: control, model and JWSNS group. OPA (HPLC) was adopted to detect the contents of amino acids in hippocampus. RESULTS: The contents of Glu and Asp in hippocampus of model group increased significantly ( P

Objective To investigate the effect of indomethacin on prevention of heterotopic ossification (HO)after operative treatment of acetabular fractures.Methods Fifty patients with acetabular fractures received in our department operative treatment through Kocher-langenbeck(K-L)approach and oral administration of in- domethacin afer operation from February 2001 to August 2003.Forty-eight of them were successfully followed up for incidence of HO and their clinical functions were assessed.The results were compared with those of 40 patients who had been treated with the same operative procedures but without oral administration of indomethacin in our depart- ment from March 1993 to May 1998.The patients who could not tolerate the drug were not included.Results The follow-ups averaged 22.8 months(range,6 to 39 months).HO occurred in eight cases.The incidence of HO was 16.7%(8/48).According to Brooker evaluation of HO,five cases were rated as degreeⅠ,three as degreeⅡ, and none as degreeⅢorⅣ.The incidence of severe HO was 0.In the control group,the incidence of HO was 35.0%(14/40)and the incidence of severe HO was 10.0%(4/40).The differences were statistically significant (P＜0.05).Conclusion Oral administration of indomethacin after operative treatment of acetabular fractures can inhibit HO.

Objective To analyze the relative factors for the prognosis in elderly patients with stroke,and provide theoretical basis for improving prognosis.Methods 188 elderly patients with stroke were treated in our department from Jan.2011 to Nov.2013,and clinical data was analyzed.The prognosis and relative risk factors for stroke were statistically analyzed.Results 99 cases had good prognosis,89 cases had poor prognosis,and the recovery rate were 52.7％ (99/188) and 47.3％ (89/188) respectively.The age was older in group of good prognosis than in group of poor proghosis (t=1.7930,P＜0.05).Univariate analysis showed that the age,position of cerebral infarction,size of lesions,hypertension,diabetes,drinking and smoking were associated with the prognosis of stroke (t=1.7930,x2 =8.6473,15.046,13.1334,4.1536,5.7004,5.9043,respectively,all P＜0.05),while the prognosis was not associated with gender,a family history of stroke,hyperlipidemia and heart disease.Multivariate logistic regression analyses revealed the prognosis of stroke was related with risk factors of age (OR=1.072),size of the lesion (OR=3.481),hypertension (OR=2.034),diabetes (OR=1.631) and smoking (OR=3.144).Conclusions It is beneficial to the prognosis of patients with stroke to stop bad habits and to treat hypertension and diabetes actively.

This paper is to report the polymorphism of raw materials of clopidogrel bisulfate at home and abroad. By the analysis of Fourier transform infrared spectroscopy (FTIR) and powder X-ray diffraction (p-XRD), samples are roughly classified into two groups, except one patent material. And the differential scanning calorimeter (DSC) examination showed more detailed information for these materials. The results of the study could provide comprehensive basis for the quality evaluation of clopidogrel bisulfate.
