Objective To study the expression of interleukin-17 (IL-17) in diabetic rat aorta and the effect of intervention with resveratrol,meanwhile,to explore the potential mechanisms of IL-17 induced diabetic vascular diseases and the protective role played by resveratrol in the epigenetic field.Methods The experiment was carried out in 4 groups:normal control group(NC),normal interventional group(NB),diabetic group(DM),and diabetic interventional group(DB),NB and DB groups were intervened with resveratrol.Immunohistochemistry was used to observe the histological localization of IL-17 and to measure the thickness of rat abdominal aorta.Western blotting,real-time PCR,and methylation-specific PCR were used respectively to compare the expression of IL-17 protein and mRNA,as well as DNA methylation in 4 groups.Results IL-17 mainly expressed in arterial intima of diabetic rats,the abdominal aorta in DM group was obviously thicker than that in NC and DB groups(P＜0.05).IL-17 protein and mRNA expressions in DM group were significantly higher than NC group(P＜0.05),and were reduced in NB and DB groups compared with NC and DM groups respectively.While DNA methylation levels of IL-17 in DM group were significantly lower than NC group(P＜0.01),however,the levels in NB and DB groups were elevated accordingly as compared with corresponding groups.Conclusions The increased levels of IL-17 in aorta of diabetic rats suggests that IL-17 is involved in the process of inflammatory responses to diabetic macrovascular diseases,while resveratrol could inhibit the expression,it may play a role in protecting aorta,and the regulation of IL-17 gene promoter DNA methylation levels may be the potential mechanism underlying these two phenomena.

Objective To analyze the cause and therapeutic effect of acute intestinal obstruction of different age groups in metropolitan. Method The data of 165 cases of acute intestinal obstruction admitted in our department from January 1995 to December 1999 were analyzed retrospectively. Patients over 60 belonged to aged group and the ones below 60 belonged to adult group. Results Among 165 cases, 98 cases belonged to the aged group while 67 belonged to the adult group. There were 68 cases of colorectal cancer, 45 cases of adhesion, 13 cases of cancer metastasis, 10 cases of volvulus of sigmoid colon, 7 cases of oblique hernia and 22 cases of other causes. Cancer was the main cause in the aged group (44.9%, 44/98) and adult group (55.2%, 37/67) (P＞0.05) . Adhesion accounted for 30. 6% (30/98) and 22.4% (15/67) in these two groups. 79.5% of the patients with colorectal cancer in the aged group and 94.6% in the adult group recieved operation(P＜0.05) . The resection rate of colorectal cancer was almost the same between the two groups. The mortality was 7.1% (7/98) in the aged group and 2.9% (2/67) in the adult group respectively(P＜0.05) . Conclusions Tumor is the main cause of acute intestinal obstruction in metropolitan followed by adhesion. The mortality is significantly high in aged group.

ObjectTo study the effect of polydatin (PD) and asymmetric dimethylarginine (ADMA) on the endothelial function in aorta vascular strips of healthy rabbits and the interaction between PD and ADMA. MethodsDose-response curves of phenylephrine (PE) on the aortic strips with or without ADMA and/or PD. E max and Kd from PE were obtained and compared. ResultsNormal aortic strips could not respond to ADMA. Pretreatment with either PD or ADMA had no effect on the contractive response of aortic strips to PE. But PD could significantly weaken the contractive response of aortic strips pretreated with ADMA caused by PE in a dose-dependent manner, increase Kd and decrease E max of PE. ConclusionEither ADMA or PD alone does not influence the normal aortic strip contractive functions, the PE affinity to ?-receptor, and E max. But PD could noncompetitively antagonize the contractive reaction of aortic strips to PE in the presence of ADMA.

Objective To determine the clinical value of hypergammaglobulinemia as a sentinel for autoimmune pancreatitis and avoid unnecessary pancreas resection.Methods All 14 patients with autoimmune pancreatitis or related pancreatic diseases underwent routine examinations,including liver function,CA199 and imaging.Measurement of serum IgG or IgG4 was performed for patients with clinically suspected or pathologically proved autoimmune pancreatitis.Clinical features were retrospectively compared between the AIP and non-AIP patients using x2 statistics with Yates correction or Fisher exact test.Results Ten cases were finally confirmed as autoimmune pancreatitis.All patients with autoimmune pancreatitis had elevated levels of serum γ-globulins,while only one case without autoimmune pancreatitis had elevated levels of serum γ-globulins.It was proved by subsequent antibody tests that serum IgG/IgG4 and γ-globulins were simultaneously increased.Conclusions Hypergammaglobulinemia can be used as a preoperative sentinel indicator for differentiating autoimmune pancreatitis from pancreatic malignancies and avoiding unnecessary pancreas operation.

Objective The development of cancer vaccines deserves experimentation,specifically the immunogenicity of the new MUC1 DNA vaccine for pancreatic cancer.Methods Three strategies were combined to optimize the new MUC1 DNA vaccine.The female C57BL/6 mice were immunized,through tibial muscle injection,with 100 μg of plasmid DNA of the recombinant plasmids (pIRES2-EGFP-3VNTR group,pIRES2-EGFP-3VNTR-C1-144 group,pIRES2-EGFP 3VNTR-mIL-18 group,pIRES2-EGFP-3VNTR-C1-144-mIL-18 group,n=5) for a total volume of 100 μl.Mice inoculated with the empty vector pIRES2-EGFP (EV group,n=5) and normal saline (NS group,n=5) were used as vector and blank controls,respectively.All the mice were immunized again every two weeks.Two weeks after the third immunization,all the mice were euthanized and spleen cells were separated for CTL cytotoxic assay.Results The specific cytolysis percentages of the four groups (pIRES2-EG-FP-3VNTR,pIRES2-EGFP-3 VNTR-C1-144,pIRES2-EGFP-3VNTR-mIL-18,pIRES2-EGFP 3VNTR-C1-144-mIL-18) expressing VNTR were higher than the EV and NS group with the effector/target cells ratio (E/T) from 80:1 to 20:1 (P＜0.05).Therefore,it showed a difference among the four groups.After the primary immunization,the OD450 of the serum antibody level specific to MUC1 began to increase in the four groups which contained the gene of VNTR3 (P＜0.05).This suggests that the recombinant plasmids could induce a specific antibody response to MUC1,and showed no remarkable difference among the four groups.IFN-γ serum cytokine among the four groups were higher than that of the EV and NS groups (P＜0.05).There was a significant difference of OD450 between the groups containing mIL-18 pIRES2-EGFP-3VNTR-mIL-18,pIRES2-EGFP-3VNTR-C1-144-mIL-18) and those not (pIRES2-EGFP-3VNTR,pIRES2-EGFP-3VNTR-C1-144,)(P＜0.05).Conclusions In conclusion,all of the four recombinant plasmids could induce MUC1 specific CTL and antibodies responses,and C1-144 and IL-18 could enhance the immunogenicity of plasmids.
