China Pharmacy 2015;(18):2509-2512
OBJECTIVE:To evaluate the efficacy of acarbose treatment in impaired glucose tolerance (IGT)and provide evi-dence-based reference for the clinical treatment. METHODS:Medline,Cochrane library,PubMed,EMBase,VIP database,CJFD and Wanfang database were retrieved to collect the randomized controlled trials(RCT)of comparison treatment(test group)of acar-bose and placebo(control group)in IGT. After the information collection and quality evaluation,Rev Man 5.0 was conducted for Mata-analysis. RESULTS:26 RCT,involving 2 221 patients were include in total. Meta-analysis result showed,compared with place-bo,acarbose could reduce FPG[WMD=-0.76,95%CI(-0.99,-0.53),P<0.001],2 h PG[WMD=-1.58,95%CI(-1.82,-1.34), P<0.001],HbA1c[WMD=-0.46,95%CI(-0.82,-0.11),P=0.01],BMI[WMD=-1.10,95%CI(-1.77,-0.44),P=0.001], TC[WMD=-0.35,95%CI(-0.59,-0.12),P=0.003],TG[WMD=-0.30,95%CI(-0.44,-0.16),P<0.001] significantly;it had no significant difference on HDL-C[WMD=-0.05,95%CI(-0.11,0.01),P=0.11] and LDL-C[WMD=-0.13,95%CI(-0.31, 0.05),P=0.17]. CONCLUSIONS:Acarbose has better efficacy in the treatment of IGT. Due to the low quality of included studies, it remains to be further verified by RCT with large sample and high quality.

Objective To study the anti-depression mechanism of Dingzhixiaowan concerning on histology of hippocampal formation.Methods 40 female rats were divided into control,depression model group(model group),distilled water group(DW group) and Dingzhixiaowan group(Chinese herb group).Behavior points were measured by open field method.Serum concentrations of cortisol and estradiol(E2) were checked with ELISA.HE staining and electron microscopy were applied to observe the histology of neurons in hippocampal formation.Immunohistochemistry method was employed to detect Nestin expression.Results Compared with the control,behavior points,serum E2 level and Nestin expression decreased obviously and serum cortisol level increased markedly,CA3 neurons were seriously damaged in model and DW groups.While behavior points,serum E2 level did not change,Nestin expression increased obviously and serum cortisol level decreased markedly,CA3 neurons were basically normal in Chinese herb groups.Conclusion Dingzhixiaowan can protect hippocampal formation,which might be one of the anti-depression mechnisms.

Objective: To investigate the effects of enamel matrix pr ot eins(EMPs) and purified EMPs(EMD) on the proliferation and protein synthesis act ivity of rat ectomesenchymal stem cells in vitro. Methods: C ell culture technique and 3H-leucine label assay were used to measure the pr oliferation and protein synthesis activity of rat ectomesenchymal stem cells exp osed to the EMPs- or EMD-conditioned culture media with different concentratio n. Results: Both EMPs and EMD at 50~200 mg/ml increased the pro l iferation and protein synthesis of the cells in 10-day-culture. EMPs and EMD a t 150 mg/ml showed the strongest effects(P

Objective To investigate the relationships between serum concentration of RBP-4 and inflammatory factors,insulin resistance in patients with gestational diabetes mellitus.Methods20 patients newly diagnosed with impaired glucose tolerance (IGT),27 patients newly diagnosed with gestational diabetes mellitus(GDM) and 50 subjects with normal glucose tolerance(NGT) were enrolled in this cross-sectional study.Additionally,another subset analysis was performed,subjects were divided on the basis of BMI into normal weight (NW) and overweight or obesity (OW/OB).Serum RBP-4 was measured with ELISA;serum concentrations of hs-CRP,free fatty acids (FFA),triglyeride(TG),total cholesterol (TC) and insulin were measured in fasting status.Insulin resistance was assessed by HOMA-IR.ResultsLn(HOMA-IR) and the concentrations of FFA,ln(hs-CRP) in IGT or in GDM were significantly higher than that of NGT(P<0.05).In the group of OW/OB,FFA[(0.90±0.31)mmol/L vs (0.71±0.28)mmol/L,t=2.73,P<0.05)],ln(hs-CRP)(0.62±1.00 vs -0.17±1.07,t=2.90,P<0.05),ln(HOMA-IR),lnRBP(0.56±0.27 vs 0.30±0.14,t=2.86,P<0.05)were significantly higher than that of NW.In the group of GDM,lnRBP-4 showed a positive relationship with FFA (r=0.231,P<0.05)and ln(hs-CRP) (r=0.237,P<0.05).There was a positive relationship between lnRBP-4 and FFA(r=0.371,P<0.05) or ln(hs-CRP)(r=0.247,P<0.05) in the group of OW/OB,but no association in the group of NGT,IGT or NW.There was no relationship between lnRBP-4 and ln(HOMA-IR) in IGT,GDM and NW,while in the group of NGT and OW/OB,lnRBP-4 showed a positive relationship with ln(HOMA-IR) (r=0.276,0.290,P<0.05).In a multiple linear regression analysis,ln(hs-CRP),FFA or ln(HOMA-IR) was not the independent factor of lnRBP-4 in any group.ConclusionsIn patients with gestational diabetes mellitus,lnRBP-4 may be a new marker of inflammation.

Objective To investigate the effects of Yishen dianpi Yangxue Tongli Fang (YSJP) on IGF-1 mRNA expression in the ovary of PCOS rat, and study its mechanism on the molecular level. Methods Seventy two female SD rats were randomly divided into normal control group, model group, clomifene group and low-, mid-, high-dose Chinese medicine group. The animal model established by capsulae levonorgestreli silasticus was used to observe the IGF-1 mRNA expression in ovary by hybridization in situ. Results IGF-1 mRNA expression of PCOS model group was higher than the normal control group obviously. The semi-quantitative image analysis showed that TCM treatment could decrease IGF-1 mRNA expression. Conclusion Yishen Jianpi Yangnue Tongli Fang could decrease the IGF-1 mRNA expression in ovary and improve the insulin resistance of PCOS rats.

Aim To study IL-8 expression of human airway epithelium-like NCI-H292 cells directly induced by Pyocyanin and its mechanism through protein kinase C(PKC) and nuclear factor-kappa B(NF-??).Methods ELISA methods were performed to test the expression of IL-8 in NCI-H292 cells infected by Pyocyanin.Western blot was employed to examine the expression of NF-?B protein.In addition,NCI-H292 cells were cultured together with PKC inhibitor,calphostin C or NF-?? inhibitor,pyrrolidine dithiocarbamate(PDTC),respectively before Pyocyanin infection,then the expression of IL-8 and NF-?? was assayed using the above methods.Results Pyocyanin was able to induce IL-8 protein secretion in NCI-H292 cells and had marked concentration-dependent relations.Pyocyanin could also significantly promote the activation of NF-?B,which peaked at 60~90 min.PDTC and calphostin C could significantly decrease the activation of NF-?? and the expression of IL-8.Conclutions Pyocyanin can induce IL-8 production.The direct induction of Pyocyanin can promote the activation of NF-?B by PKC signal pathway,then cause the expression and secretion of IL-8.
