Nonalcoholic fatty liver disease(NAFLD)has become one of the most common liver diseases in the world.Considering the important role of insulin resistance in its pathogenic mechanisms,insulin sensitizers are becoming the promising pharmacological strategies for NAFLD.We collected and analyzed the relevant articles in recent years and found that pioglitazone,rosiglitazone and metformin could improve liver enzymes and insulin sensitivity of NAFLD.However,only pioglitazine was supported in ameliorating liver histology by envidences from randomized,double-blinded,controlled clinical trials.There were no much obvious adverse effects in NAFLD patients who received insulin senitizers.Small or medium samples and no more than 2 years of treatment course may be the major limitation of current studies.Future information derived from well-designed running trials will be useful in defining the clinical implications of insulin sensitizers in the treatment of NAFLD.

Objective To explore the feasibility and importance of active monitoring of vancomycin‐related nephrotoxicity .Meth‐ods During July 2010 to July 2013 ,a total of 139 cases of inpatients received vancomycin through intravenous injection were en‐rolled in this study .The adverse drug reaction active monitoring and early warning system were utilized to evaluate patients with vancomycin positive events .Results Among the 139 cases of patients ,there was 9 cases of patients with renal damage .The inci‐dences of compensatory stage of renal insufficiency ,decompensatory stage of renal insufficiency ,renal failure stage and end‐stage re‐nal failure were 44 .44% ,22 .22% ,22 .22% and 11 .11% respectively .The positive warning rates when serum creatinine level was above 133 μmol/L ,increased by 50% compared with the baseline ,increased with 44 μmol/L based on the baseline were 55 .56% , 22 .22% and 22 .22% respectively ,and those positive warning rates in artificial relevance evaluation were 19 .18% ,19 .18% and 56 .54% respectively .Conclusion It is necessary to individualize utilization of vancomycin according to patients′s condition .

Rotavirus (RV) is one of the major pathogens responsible for acute viral gastro-enteritis in children. The infec-tion of RV is dependent upon the recognition of the host cell speciifc receptors and attachment. Thus, receptors are the important factors of infection. Recent studies have suggested that a genetic factor might play a role in the susceptibility of hosts to RV infec-tion. Histo-blood group antigens have recently been discovered as receptors binding to RV, which are important for the study of evolution. Thus it will be also crucial for the pathogenesis and epidemiology and prevention and treatment for RV. In this article, we will review the correlation of the RV infection and histo-blood group antigens and further discuss the development of optimal vaccine.

Objective To investigate the blocking effects of Pyrin domain protein on mouse allergic airway inflammation induced by ovalbumin and its mechanism.Methods Forty male BALB/c mice were randomly divided into 4 groups with 10 mice in each group.Control group:mice were treated with saline;OVA group:mice were sensitized and challenged with OVA; Pyrin domain protein 3 d group:mice were sensitized and challenged as asthmatic group and treated with 100 μg/kg triptolide before challenged; Pyrin domain protein 7 d group:mice were sensitized and challenged as asthmatic group and treated with 100 μg/kg triptolide before challenged.All mice were killed 24 h after final OVA challenge.The left lung was isolated for pathological examination.Lung sections were stained with hematoxylin and eosin(HE),Masson's trichrome.The thickness of bronchial airway,bronchial smooth muscle thickness,and the collagen deposition area were measured by image analysig system.The concentrations of IL-4,IL-5,TNF-α and IFN-γ in BALF were measured by ELISA,the RT-PCR and Western blot was performed to detect the mRNA expression of connective tissue growth factor (CTGF),TGF-β 1 mRNA and NF -kB from the right lung tissues.Results In OVA group,the number of inflammatory cells and the concentrations of IL-4,IL-5,TNF-a in BALF and Bronchial airway thickness,bronchial smooth muscle thickness,the collagen deposition area,CTGF,TGF-β1 mRNA and NF-kB in lung tissue were significantly higher than those in control group(P＜0.05).IFN-γ were lower than those in control group( P＜0.05 ).While in Pyrin domain protein 3 d group and Pyrin domain protein 7 d group,the number of inflammatory cells,the concentrations of IL-4,IL-5,TNF-α in BALF and bronchial airway thickness,bronchial smooth muscle thickness,the collagen deposition area and NF-kB in lung tissue were significantly lower than those in OVA group,IFN-γwere higher than those in OVA group( P ＜0.05).In Pyrin domain protein 7 d group CTGF and TGF-β1 mRNA in lung tissue were significantly lower than those in OVA group.Conclusion Pyrin domain protein might inhibits airway inflammation and development of airway remodeling in asthmatic mouse,the possible mechanism might in part by associated with reducing the expression of NF-kB and further inhibiting CTGF,TGF-β1.

Objective To study the part of Anti-thrombus and its property from Ground Beetle. Methods To dispart the Ground beetle into four segments which were shell, head, chest and abdomen, and adopt the method of frozen and melt to do the further test. Result Extracts of shell and chest were not active, extracts of head and abdomen were active. The activity of abdomen extracts was much better than that of the insect extracts. Its active component was glycoproteins. Conclusion The activity of abdomen extracts (Tf) is relatively high, and demonstrates wider value.

Objective To study the adsorbability of active carbon fiber(ACF) for gaseous benzene and to use ACF for the determination of benzene in the air in future.Methods The adsorbability of ACF was investigated and the results were compared with that of granular active carbon(GAC).Results The adsorption efficiency of ACF was 93%,the selective adsorbability was 94.28%,the saturation adsorption capacity of gaseous benzene was 25%,as for GAC,they were 88%,88.57% and 12% respectively.Conclusion ACF is better than GAC in the adsorption efficiency of benzene in the condition of low concentration and long time sampling.

Objective To study the effect of inducible nitric oxide synthase(iNOS)on the occurrence of ischemic cerebral stroke in passive smoking female.Methods 100 passive smoking female patients with ischemic cerebral stroke(passive smoking group) according to the passive smoking index were divided into sub-groups index 900;25 cases in each group.The level of serum iNOS and the situation of carotid atherosclerosis were detected.The resules were compared with healthy female who without smoking and passive smoking(normal control group).Results Compared with the normal control group,the levels of serum iNOS,the intimal media thickness(IMT)s of carotid artery and the positive rates of carotid atherosclerosis plaque in each passive smoking index sub-group were significantly increased(all P
