The (GCT)o polymorphism of the MICA gene was investigated in 100 patients with latent autoimmune diabetes in adult (LADA) and 145 healthy controls by PCR and denaturing polyacrylamide gel electrophoresis.The A5.1 allele was present at a significantly higher frequency in LADA group (0.340) than that in control group (0.183) (P

Complement system is an important constituent in immune system.Membrane attack complex (C5b-9)is the final ingredient in the complement activation.Recently,a few studies showed that C5b-9 deposition was found in the diabetics with chronic complications,indicating that complement activation might be involved in the pathogenesis of diabetic complications.Our aim is to summarize some newly published works and show a prelimimary work we did in this area.We hope that more attention should be paid to the role of autoimmune mechanism in diabetic complications.

Objective To study the level of immunoglobulin and the prevalence of ANA in patients with Graves' diseases(GD).To explore the correlation between GD and other systemic autoimmune disorders.Methods Data of 145 patients with GD and 45 healthy subjects were collected.All cases were detected on the presence of ANA and the level of immunoglobulin,FT3,FT4,and thyroid specific antibodies.Results The presencerate of ANA and the level of IgG in patients with GD were higher than that in healthy controls [(28.28% vs 4.55%);(70.96?26.14 vs 60.41?11.01) mmol/L](P

Objective To determine the probability of identification of differential expression of biliary proteins induced by cholangiocarcinoma using 2D-DIGE. Methods Bile was obtained from 12patients with obstructive jaundice (including 6 cases of cholangiocarcinoma and 6 of cholelithiasis).Each sample was labeled with three different CyDyes (y3,Cy5,Cy2) including one internal standard,pooled from all the samples, and separated with 2-D DIGE in triplicate experiments. MALDI-TOF-MS and bioinformatics were adopted to identify and elucidate the significance of differentially expressed proteins in bile induced by cholangiocarcinoma. Results 55 matched protein spots differences in abundance were detected with statistical variance of two groups(Average Volum Ratio ≥1.5, t-test, P＜0. 05). Among these proteins, 13 PMF were obtained by MALDI-TOF-MS analysis. Eight proteins were identified by searching a protein database. Conclusion The differentially displayed proteomes between the pathological bile obtained from benign and malignant obstructive jaundice indicates the potential application of 2D-DIGE to identify the biomarker of cholangiocarcinoma.

The depositions of immunoglobulins on the retina of diabetic rat were studied with immunohistochemistry,immunofluorecence and computer analysing system.In comparison with control group, depositions of IgG,IgA and IgM on the retina of diabetic rat induced by streptozotocin were significantly increased (all P＜0.05 ).So the immunoglobulin depositions may contribute to the pathogenesis of diabetic retinopathy.

The polymorphism of (AT) repeat within the 3' untranslated region in exon 3 of CTLA-4 gene was evaluated by PCR-SSCP in 139 patients with Graves' disease (GD) and 110 normal subjects in Tianjin. The gene frequency of 106 bp in patients with GD was significantly increased than that in the control group (RR =1.992,P
