Objective To study the inhibitory effects of angelica A_3 active fraction (A_3) inflammation and up-regulation of cyclooxygenase-2 (Cox-2) expression of rat uterus induced by lipopolysaccharides (LPS). Methods The anti-inflammatory effects of A_3 were investigated in rats using the carrageenin-induced paw swelling model and in mice using dimethylbenzene-induced ear edema model; RT-PCR and Western blotting were used to analyze Cox-2 mRNA and the protein expression levels. Results A_3 (1, 5, and 10 mg/kg) dose-dependently inhibited dimethylbenzene-induced ear edema in mice and paw swelling in rats by ig administration. LPS 1 ?g/mL could significantly increase the level of Cox-2 mRNA and protein expression. A_3(10—320 mg/L) could concentration-dependently inhibit Cox-2 mRNA and protein over-expression stimulated by LPS. Conclusion A_3 possesses better anti-inflammatory effects than angelica oil, which maybe relates to its inhibitory effects on Cox-2 overexpression.

Objective To investigate the role of IFN-γ and FOXP3 expression in subpopulation distribution and functions of tumor-infiltrating lymphocytes (TILs) in the microenvironment of renal cell cancer.Methods 30 renal cell cancer tissue samples were freshly collected from the laparoscopic radical nephrectomy in the first hospital of Jiaxing.After frozen sectioning,immunofluorescent staining was conducted to detect the infiltrating CD4 positive and CDs positive cells,and the expression of FOXP3 and IFN-γ as well.In addition,TILs were isolated from the tumor tissues by density-gradient centrifugation.TILs from tumor center or tumor invasive edge were purified independently and measured for the mRNA levels of FOXP3 and IFN-γ by qRT (quantitative reverse transcription)-PCR.Results Tumor-infiltrating CD4+ and CD8+ T cells were concentrated in the invasive edge of renal cell cancer tissues.The expression of FOXP3 was found to be inversely related to that of IFN-γ from the immunofluorescent staining.The relative FOXP3 mRNA levels for the TILs from tumor center and invasive edge were 64.6 ± 9.4 and 36.2 ± 1.8,respectively,with significant difference(P ＜0.05).The relative IFN-γ mRNA levels were 631.8 ± 151.4 and 1 726.0 ± 344.1 (P ＜ 0.05).The trend of relative expression of FOXP3 was reversed in terms of IFN-γ.Conclusions The study on the renal cell cancer tissue samples suggested that the tumor-specific cytotoxic immune cells relatively concentrated in the tumor invasive edge.

Objective To investigate the prevalence and risk factors of hyperuricemia (HUA) in rural residents of Gaoyou City,Jiangsu Province.Methods A total of 4504 rural residents were investigated in a cross-sectional study.Questionarre survey and physical examination were used for the stndy.Fatsing venous blood samples were collected for biochemical examination.T-test,chi-square test for multiple-group data comparison and logistic regression analysis were used for statistical analysis.Results The prevalence of HUA was 11.9％,15.7％ in male,which was significantly higher than 8.6％ in the female (P＜0.01),the risks of HUA in male was 1.98 times higher than in female.The average value of serum uric acid in this population was higher than.that of female.The prevalence of HUA in female increased with age.Non-conditional logistic regression analysis showed WHR,Cr,Tg,hypertension were the independent risk factors of male patients with HUA.Age,BMI,Cr,Tg,hypertension were independent risk factors of HUA in female.Conclusion The prevalence of HUA can be affected by age and sex.Weight control,keeping blood pressure and blood lipid profiles in normals levels are important for the prevention of HUA.

Objective To investigate the relationship between serum levels of homocysteine (HCy) and adiponectin (APN) in patients with type 2 diabetes mellitus(T2DM).Methods 65 patients with T2DM (diabetes mellitus group) and 25 healthy controls (control group) matched in the age and sex were recruited in the study.Serum HCy,APN,fasting plasma glucose (FPG),fasting insulin (FINS),total cholesterol (TC) and triglyceride (TG) were simultaneously measured.The homeostatic model assessment for insulin resistance(HOMA-IR) was calculated according to FPG and FINS.All the serum indicators were compared between the two groups.Results Serum level of HCy in T2DM group was (15.74 ± 2.76) μmol/L,which was significantly higher than (6.98 ± 1.94) μmol/L in the healthy control group (t =16.88,P ＜ 0.01).The serum level of APN in T2DM group was (8.14 ± 2.70) mg/L,which was significantly lower than (16.10 ± 1.93)mg/L in the healthy control group (t =13.44,P ＜ 0.01).Serum levels of FPG,HOMA-IR,TC,TG in T2DM group were significantly higher than those in the healthy control group (t =10.62,17.49,6.30,7.52,P ＜ 0.05).Serum level of APN in HCy ≥ 15μmol/L group was significantly decreased compared with HCy ＜ 15μmol/L group.Serum level of HCy was negatively correlated with APN in T2DM group after the influence of FPG,HOMA-IR,TG,TC were corrected in the partial correlation analysis.Conclusion In T2DM group,serum level of HCy was increased,but serum level of APN was decreased,serum HCy was negatively correlated with APN,higher serum level of HCy and lower serum level of APN are related with the process of insulin resistance and T2DM.

OBJECTIVETo study the effect of dehydroepiandrosterone sulfate (DHEAS) treatment of osteoporosis in men with T(BMD) > or = 2.5SD.

METHODSEighty-six patients were randomly divided into two groups: treatment group (n = 44) and control group (n = 42). DHEAS (100 mg q.d.) was given to the treatment group for 6 months. Bone mineral density, (BMD), biochemical markers of bone absorption and formation and other serum biochemical markers were measured before and after DHEAS treatment. Drug side effects were also evaluated.

RESULTSAfter oral administration of DHEAS (100 mg q.d.) for 6 months, the serum concentrations of DHEAS and IGF-I in the treatment group were 93.75% +/- 16.1% and 17.71% +/- 4.2% higher respectively than those in the control group (P < 0.01). The BMD of L2, L3, L4, L2 - 4 and Neck sections increased in the treatment group by 2.65% +/- 0.65%, 2.70% +/- 0.48%, 3.10% +/- 0.41%, 2.82% +/- 0.37% and 2.32% +/- 0.31%, respectively, as compared with that the control group (P < 0.05 or 0.01). No significant changes were observed in serum FT, E(2) and PSA concentrations in the treatment group as compared with the control group.

CONCLUSIONThe treatment of osteoporosis in men with DHEAS is safe and effective.

Objective To study the therapeutic effect of anti-CD80 bivalent antibody on mouse lu-pus nephritis and to explore the possible molecular mechanism. Methods A mouse model of lupus nephritis was established through intraperitoneal injection of 0. 5 ml of pristine in female C57BL/6J mice. Appearance of urinary protein and significantly increased levels of peripheral antinuclear antibody ( ANA) and anti-doub-le-stranded DNA ( anti-dsDNA) antibody in the fourth month after injection indicated that the mouse model was established successfully. Then the mice were divided into two groups including anti-CD80 bivalent anti-body intervention group (injected with 200μg of anti-CD80 bivalent antibody at day 1, 3, 5, 8 and 15, fol-lowed by three times of injection with an interval of one month) and model group ( injected with the same protein using the same strategy). A normal control group was set up accordingly. Albustix test paper was used to monitor the dynamic changes in mouse urinary protein. Flow cytometry was used to analyze the acti-vation of immune-related cells in spleen. Levels of autoantibodies ( ANA and anti-dsDNA) and levels of IFN-γ and IL-4 in serum were detected by indirect immunofluorescence assay. Renal tissue samples were an-alyzed with hematoxylin and eosin ( HE) staining and immunocomplex ( IC) assay. Results Urinary pro-tein level of the anti-CD80 bivalent antibody intervention group was significantly lower than that of the model group (P<0. 05). Activated macrophages, dendritic cells, neutrophils and B cells in spleen tissues of the anti-CD80 bivalent antibody intervention group were significantly less than those of the model group ( P<0. 05), and the numbers of CD4+ and CD154+ T cells were significantly less than those of the model group (P<0. 05). Positive rates and titers of ANA and dsDNA in serum samples of the intervention group were lower than those of the model group (P<0. 05). Levels of IFN-γand IL-4 in serum samples of the interven-tion group were decreased as compared with those of the model group (P<0. 05). HE staining and immuno-fluorescence assay showed that glomerular inflammatory injury and necrosis were alleviated and kidney im-mune complex deposition was reduced after anti-CD80 bivalent antibody intervention. Conclusion Anti-CD80 bivalent antibody specifically binds to the CD80 molecule on antigen presenting cell surface, blocks the CD80/CD28 co-stimulatory signaling pathway and down-regulates the body′s immune response, which al-leviates and reverses the lupus-like nephritis-induced pathological damages in mice.

Objective: To investigate the level of foot care behaviors of in patients with type 2 diabetes mellitus in Jinshan District of Shanghai, analyze the influential factors, and provide information for the intervention study. Methods: With convenient sampling method, a questionnaire survey was conducted with a sample of 110 inpatients with type 2 diabetes mellitus from Jinshan District of Shanghai. The investigation contents included patients′ demographic data, foot care knowledge and behaviors. The investigation tools were the questionnaire of diabetes general information, the questionnaire of foot care knowledge, and the questionnaire of foot care behaviors. Survey tools included general information questionnaire, foot care knowledge scale for diabetic patients and Nottingham Foot Care Assessment Scale in Chinese version. Independent-samples t test and oneway ANOVA were used in univariate analyses, whereas multiple stepwise linear regression was used in multivariate analyses. And Pearson correlation analysis was used to measure correlation between variables. Results: The scores of foot care behaviors were statistically significant in the group comparison of sex and glycosylated hemoglobin(t=-2.142, F=3.071, P<0.05). The patients′score of foot care behaviors was (45.31±7.74) scores. 50.9 percent (54/106) patients′scores were less than 45. And the score of foot care knowledge was (16.10±4.18) scores, which was in the medium level. The foot care behaviors level was lower in the patients whose foot care knowledge was poorer (t=-5.591, P<0.01). Foot care knowledge, glycosylated hemoglobin level and gender were the main influencing factors on foot care behaviors of type 2 diabetic patients (R²=0.221, F=9.664, P=0.000). Pearson analysis demonstrated that there was a positive correlation between knowledge score, glycosylated hemoglobin level and behavior score (r=0.377, 0.207, P<0.05). Conclusions The status of foot care knowledge and behaviors of type 2 diabetic patients are not optimistic in Jinshan District of Shanghai. It′s very important to strengthen the education and management on diabetic patients′foot care knowledge and behaviors, especially in male patients. Meanwhile, the patients whose glycosylated hemoglobin are well controlled should not be ignored.
