Objective To observe the effects of fosinopril(FOS)on secretion of ColⅠ,expression of Smad2、Smad7 mRNA in TGF-β1-induced glomerulomesangial cells(GMC)in rat model. Methods Rat glomerular mesangial cells were cultured in vitro,passages 3 - 10 cells were used in the study after identification,and the cells were divided into 3 groups:control group(Ctrl group),TGF-β1 group,and fosinopril group. Expression of Col Ⅰ in cell culture supernatant was detected by the enzyme-linked immunosorbent assay(ELISA)at 6 h,24 h and 48 h. Changes of Smad2,Smad7 mRNA expression were evaluated by fluorescent quantitation PCR. Results Glomerular mesangial cells had Col Ⅰ protein expression. Secretion of Col Ⅰ was significantly higher in TGF-β1 group than those in Ctrl group at each time point(P ＜ 0.01),however the Col Ⅰ was significantly lower in fosinopril group at all time points than that in TGF-β1 groups(P ＜ 0.05). Glomerular mesangial cells also had Smad2,Smad7 mRNA expressions. The expressions of Smad2,Smad7 mRNA were significantly higher in TGF-β1 group than those in Ctrl group at each time point. Expression of Smad2 mRNA was significantly lower in fosinopril group than that in TGF-β1 group at all time points,while the difference in Smad7 mRNA expression between TGF-β1 group and fosinopril group showed no statistical significance(P ＞ 0.05). Conclusions Fosinopril could inhibit the secretion of Col Ⅰ and expression of Smad2 mRNA in glomerular mesangial cells induced by TGF-β1,suggesting that fosinopril might delay glomerular sclerosis through inhibiting the expression of Smad2 in TGF-β1/Smad signaling pathway.

Objective:To study the effects and safety of metformin combined with vildagliptin on the glycemic control for patients with newly diagnosed type 2 diabetes mellitus.Methods:60 patients with type 2 diabetes mellitus who were treated from February 2015 to April 2016 were selected and divided into the control group and the observation group according to different treatment methods.The control group was treated with routine treatment.The observation group was treated with vildagliptin based on the control group.The blood glucose,glycosylated hemoglobin,two-hour postprandial blood glucose and serum as well as urinal amylase were measured before and after treatment,and the clinical curative effect of the two groups and the levels of interleukin-6,tumor necrosis factor and C-reactive protein were compared.Results:After treatment,the total effective rate of observation group was 90％,which was significantly higher than that of the control group(66.7％,P＜0.05).After treatment,the serum interleukin-6,tumor necrosis factor,C-reactive protein and fasting blood glucose,glycosylated hemoglobin and postprandial blood glucose levels were significantly lower than those of the control group[(7.63± 1.12)dvs(8.68± 1.30)d;(7.23± 0.95)d vs(7.89± 1.20)d;(11.14± 1.56)d vs(12.12± 1.89)d];[(12.12± 1.89)d vs(ll.20± 1.34)d;(6.89± 0.96)d vs(8.23± 1.10)d;(1.65± 0.23)d vs(3.65± 0.48)d] (P＜0.05).After treatment,the INS level of observation group was significantly lower than that of the control group (P＜0.05) and the GLP-1 level was significantly higher than that of the control group (P＜0.05).Conclusion:Metformin combined with vildagliptin could effectively control the blood glucose of patients with newly diagnosed type 2 diabetes and enhance the safety.

Objective To explore the physical and mental health status on the ‘left behind ’ students in Anhui province and the related influential factors.Methods Stratified cluster sampling method was used to investigate the 682 out of 3421 students from 7 middle schools in both south and north Anhui province,using multidimensional sub-health questionnaire of adolescents (MSQA) and mental health test (MHT),for assessment of the general condition,physical and mental health status.Results 14.22％ of the ‘left behind’ students were in sub-health condition compared to 11.28％ among the normal students,and the mental sub-health status represented 13.64％ for the former and 10.84％ for the latter.In addition,the ‘left behind’ students appeared less content with their life than those of staying with their parents (P＜0.05).MHT scores in the subjects were positively correlated with the scores on MSQA and showed significant difference (P＜0.01).Results from the multiple linear regression analysis showed that the mental health condition among the left behind students was in linear regression relationship with the decreased physical activity (β =1.456,P=0.001 ),emotional problems (β =1.096,P=0.000 ) and problems of social adaptation (β=1.011,P=0.006).The status of physical sub-health in the Anhui province showed that there was no significant difference in each of the study group (P＞0.05).Conclusion Decreased physical activity and emotion aporia as well as difficult social adaptation were major factors leading to degenerated mental health levels in the‘left-behind’ adolescents.The findings suggested that the mental health status could be improved inthis population through better management on their body-health condition.

This study was aimed to investigate the effect of beta-elemene on proliferation and apoptosis of human multiple myeloma cell line RPMI-8226 and its mechanism. The effect of beta-elemene on the growth of human multiple myeloma cell line RPMI-8226 was detected by MTT. The effect of beta-elemene on the apoptosis of RPMI-8226 cells was determined by flow cytometry with Annexin-V/PI staining. The effects of beta-elemene on the expression of BCL-2, caspase-3, DR-4 and NF-kappaB P65 proteins were analyzed by Western blot. The results showed that the beta-elemene obviously inhibited the proliferation of RPMI-8226 cells in both time- and dose-dependent manners. Treatment with 10 - 80 micromol/L beta-elemene for 48 hours induced apoptosis of RPMI-8226 cells in a dose-dependent manner. The expression of caspase-3 and DR-4 proteins in RPMI-8226 cells treated with beta-elemene increased in a time-dependent manner, while expressions of BCL-2 and NF-kappaB P65 proteins decreased. It is concluded that the beta-elemene can inhibit the proliferation of RPMI-8226 cells by inducing the cell apoptosis. Activating the mitochondrial and death receptor pathways of apoptosis and inhibiting the anti-apoptosis pathway may involve in the beta-elemene-induced apoptosis.

OBJECTIVEDendritic cells an hyperinsulinemia are both implicated in the pathogenesis of atherosclerosis. The aim of this study is to explore the effect of high concentration of insulin on the maturation of monocyte-derived dendritic cells (MoDCs) and related signal transduction pathways.

METHODSHuman monocytes were purified (over 98%) using Anti-CD14 micro-beads and cultured for 5 days with DC Cellgro medium containing rhGM-CSF (100 microg/L) and rhIL-4 (20 microg/L). Immature DC were then incubated with insulin of various concentrations (0, 1, 10, 100 nmol/L) for 24 hours in the presence or absence of LY294002 (PI3K inhibitor) or PD98059 (MAPK inhibitor). Immunophenotypic expression of CD86 and CD83 were detected using flow cytometry. Endocytosis function of the MoDCs was evaluated using FITC-Dextran and MoDCs secretion IL-12, IFN-gamma and TNF-alpha were measured by ELISA.

RESULTSInsulin induced significantly higher CD83 and CD86 expressions on MoDCs in a dose-dependent manner. The endocytosis function of MoDCs were significantly inhibited and cytokine secretions of IL-12, IFN-gamma and TNF-alpha significantly increased by 10 nmol/L and 100 nmol/L insulin. These effects could be blocked by the LY294002 and PD98059.

CONCLUSIONHyperinsulinemia contributed to atherosclerosis via stimulating immune maturation of MoDCs via both PI3K and MAPK pathways.

OBJECTIVESTo investigate CD3+CD56+ lymphocytes and their subsets in the peripheral blood of chronic hepatitis B patients and to explore the relationship between these cells and the pathogenesis of their diseases.

METHODSBlood samples from 53 chronic hepatitis B patients, 17 from HBV asymptomatic carriers (ASC) and 19 from healthy controls (HC) were collected. CD3+CD56+ lymphocytes were detected by flow cytometry (FCM), then the CD3+CD56+ lymphocytes were gathered to analyze their expressions of CD4, CD8, TCR Valpha24, TCRalpha/beta and TCRgamma/delta.

RESULTSThe number of CD3+CD56+ lymphocytes of chronic hepatitis B patients (7.4+/-4.6%) was more than those of ASC (4.5%+/-3.5%) and healthy controls (4.4%+/-3.7%). The expressions of TCR Valpha24 on CD3+CD56+ lymphocytes showed no significant differences among the three groups, but the expression of TCR Valpha24 on CD3-CD56+ lymphocytes of ASC ( 2.8%+/-1.4% ) was much more than that of the HC (1.7%+/-1.0%). For the subsets analysis, the CD8 and TCRalpha/beta subsets of CD3+CD56+ lymphocytes of chronic hepatitis B (61.9%+/-16.8% and 68.1%+/-16.9%) were significantly higher than those of the HC (49.2%+/-15.6% and 56.4%+/-17.9%), while the TCRgamma/delta subsets of chronic hepatitis B and ASC (29.6%+/-15.4% and 30.5%+/-14.8%) were decreased significantly than those of the HC (41.4%+/-19.4%). On the other hand, the CD8 and TCRalpha/beta subsets of CD3+CD56+ lymphocytes of severe chronic hepatitis B (69.0%+/-14.0% and 76.1%+/-12.9%) and CD8 subsets of moderate chronic hepatitis B patients (66.4%+/-14.9%) were significantly higher than those of the mild chronic hepatitis B patients (51.4%+/-16.2% and 62.1%+/-14.6%).

CONCLUSIONThe pathogenesis of chronic hepatitis B may positively relate to the high expression of CD8 on the CD3+CD56+ lymphocytes.
