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 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 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 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.

Objective To investigate the human papillomavirus 16/18 (HPV16/18) infective status and its relationship with the expression of p16,CK17,Ki-67 in immature squamous metaplasia(IM),cervical intraepithelial neoplasia (CIN) and cervical carcinomas (CC).Methods In situ hybridization (ISH) and immunohistochemistry were applied to detect the expression of HPV16/18,p16,CK17,Ki-67 on tissues from 30 IM,60 CIN and 30 CC.Results The expression rates of HPV16/18 in LSIL,HSIL and CC were 30 ％ (9/30),60 ％ (18/30) and 77 ％ (23/30),higher than that in IM [6.7 ％ (2/30)].HPV16/18 was positively expressed with the progression of cervical squamous epithelial lesions.The expression rates of CK17 in IM was 90 ％ (27/30),higher than that in LSIL,HSIL and CC [17 ％ (5/30),10 ％ (3/30),6.7 ％ (2/30)].The expression rates of p16,Ki-67 were 83 ％ (25/30) and 87 ％ (26/30) in LSIL,90 ％ (27/30) and 93 ％ (29/30) in HSIL,97 ％ (29/30) and 97 ％ (29/30) in CC,higher than that in IM [13 ％ (4/30) and 10 ％ (3/30)].The expression of p16,Ki-67 were particularly seen in HPV16/18-positive HSIL and CC,and the correlation were observed.Conclusion HPV16/18 infection is highly associated with the degree of squamous intraepithelial neoplasia and carcinomas of cervix and upregulated p16 and Ki-67,which suggested that HPV16/18 maybe cause mutation of p16 gene.With the progression of cervical squamous epithelial lesions,positive expression rates of CK17 were decreased compared with increased of HPV16/18,p16,Ki-67.Combined detection of HPV16/18,p16,Ki-67 is helpful for diagnosis and classification of cervical squamous epithelial lesions.

Objective To evaluate the diagnostic value of MRI in hepatic echinococcosis.Methods MRI features of 37 cases with hepatic echinococcosis proved by operation and pathology were analysed in comparison with that of CT.Results The hepatic echinococcosis could be divided into five types according to the manifestations of CT and MRI:simple cyst in 8 cases,multiple daughter cyst in 13 cases,ruptured cyst in 7 cases,consolidated and calcified cyst in 4 cases and mixed cyst in 5 cases.Conclusion MRI can clearly show and determine the location,size,form,number and types of hepatic echinococcosis,that are helpful for the plan of operation.

OBJECTIVE: To evaluate the clinical efficacy of Cefepime in treating senile patients with hospital acquired pneumonia(HAP).METHODS: A total of 60 HAP cases were randomly assigned to receive Cefepime(n=30) or Ceftazidime (n=30) for 7～10 days.The effective rate and the bacterial clearance rate of two groups were compared.RESULTS: The effective rate was 86.7% for Cefepime group and 70.0% for Ceftazidime group(P
