3.Investigation on relation between recurrent spontaneous abortion and antiphospholipid thrombosis syndrome
Acta Universitatis Medicinalis Anhui 2001;(2):137-138
Objective To investigate the causes of recurrent spontaneous abortion(RSA) and to know the relation between RSA and antiphospholipid thrombosis syndrome(APL-T). Methods ELISA and PTT-LA were used to detect anticardiolipin antibody(ACA) and lupus anticoagulant(LA) in 32 patients with RSA and 20 normal controls(NC). Results There were 17 positive of antiphospholipid antibody(APA) in RSA group. The incidence was significantly higher than that in NC group. The incidence of LA was also significantly higher than that in NC group. 8 patients were diagnosed as APL-T. Conclusion LA may be the more important reason of RSA. It should be considered as APL-T when RSA is unexplained.
5.Effect of IL-10 in tumor
Journal of International Oncology 2013;(3):181-184
Interleukin-10 (IL-10) is an immuno-regulatory cytokine,which is well known for its immunosuppressive function.IL-1O can act on a variety of immune cell subsets and play an immunosuppressive effect through a variety of ways.It plays an important role in the tumor immune escape.Recent studies show that IL-10 also has an immune-stimulating function,which is presumably a pluripotent cytokine.This paper will combine the latest literature to summary the positive and negative regulatory roles of IL-10,mediation ways in the tumor and the relationships with prognosis.
6.Heme oxygenase-1 downregulates mucous hypersecretion induced by cigarette smoke in cultured A549 cells
Basic & Clinical Medicine 2010;30(3):246-251
Objective To investigate the effects of heme oxygenase-1 (HO-1) on the signal transduction pathway of mucin(MUC) expression induced by cigarette smoke.Methods The cell model of mucous hypersecretion was made by human lung A549 cell stimulated by cigarette smoke extract(CSE),the cells were divided into 4 groups:negative control group,CSE treatment group,heroin pre-treatment group and ZnPPIX pre-treatment group.The expression of MUC5AC,epidermal growth factor receptor(EGFR),p-EGFR,HO-1 and dual oxidase 1 (Duoxl) were detected.The cell activity was assessed by methyl thiazolyl tetrazolium method.The change of HO-1 mRNA,Duoxl mRNA,EGFR mRNA and MUC5AC mRNA was examined by reverse transcriptase-polymerase chain reaction.The protein expression of EGFR,p-EGFR,Duox1 and HO-1 was measured by Western blot,while the pro tein expression changes of MUC 5 AC were detected by ELISA.Results The expression level of MUC 5 AC mRNA and its protein in the CSE group increased significantly (P<0.05) as compared to those in the control group [0.412±0.043,(105±8) μg/mg.The mRNA and protein of EGFR,Duox1 and HO-1,the protein of p-EGFR increased significantly as compared to the control group.After the cells being pre-treated with hemin,the mRNA and protein of HO-1 increased significantly,while the mRNA and protein of Duox1,EGFR and MUC,SAC,the protein of p-EGFR decreased significantly as compared to the CSE group.After the cells were pre-treated with ZnPPIX,the increase of HO-1 mRNA and protein was not significant as compared to the control group,while the mRNA and protein of Duox1,EGFR and MUCSAC,the protein of p-EGFR increased significantly.Conclusion HO-1 decreased the level of Duox1,blocked ligand-dependent EGF-R activation and decreased the expression levels of MUCSAC.
7.Universal Health Coverage in China and development strategies
Chinese Journal of Hospital Administration 2013;29(8):561-564
Objective Perform a quantitative analysis on the development stage of Universal Health Coverage (UHC)in China and discuss key options for scaling up UHC in China.Methods Quantitative addition model was used to analyze the UHC trend in China from 2003-2011,along with a sensitivity analysis and international comparison with the UK.Results The quantitative analysis showed that the UHC in China,for the year of 2003,2008 and 2011 were 2.79,2.32 and 2.60 respectively.Sensitivity analysis showed the integration of the health insurance schemes and scaling up the risk pooling levels contributed more than other factors to UHC in China.Conclusion The UHC in China has been developed to the mid-stage,but still lags far behind developed countries like the UK.Such general measures as equalization of benefits and scaling up of the risk pooling level should be taken.First of all,equalization of medical benefits for both rural and urban residents makes the fundamental priority and policy in the pursuit of UHC in China.
8.Analysis of the risk factors of portal vein thrombosis in liver cirrhosis patients
Acta Universitatis Medicinalis Anhui 2014;(10):1505-1507
To research the risk factors of portal vein thrombosis( PVT) in liver cirrhosis patients. 110 cirrhotic pa-tients with ( n =39 ) or without ( n =71 ) PVT diagnosed were enrolled. 12 common ultrasonographic and serum markers were analyzed. SPSS software was used for statistic analysis. Single factor analysis and Logistic regression model analysis showed that fibrinogen was the independent risk factor of portal vein thrombosis( PVT) in liver cir-rhosis patients. Fibrinogen should be monitored in patients with cirrhosis to prevent and find the occurrence of portal vein thrombosis.

10.Effects of Cigarette Smoke Extract on Signal Transduction Pathway of MUC5AC Mucin Expression in A549 Cells
Journal of Environment and Health 1992;0(02):-
Objective To investigate the effects of heme oxygenase-1 (HO-1) on the signal transduction pathway of cigarette smoke-induced mucin (MUC) expression in airway mucous hypersecretion. Methods The cell model of mucous hypersecretion was made by human lung A549 cell stimulated by cigarette smoke extract (CSE),and treated with hemin or ZnPPIX,an inductor or inhibitor of HO-1. The expression of HO-1,dual oxidase 1(Duox1),MUC5AC,epidermal growth factor receptor (EGFR) and p-EGFR were detected. The cell viability treated with hemin or ZnPPIX was assessed by methyl thiazolyl tetrazolium method (MTT). The cells were divided into 4 groups:a negative control group,a CSE treatment group,an hemin pre-treatment group and a ZnPPIX pre-treatment group. The changes of EGFR mRNA,Duox1 mRNA,HO-1 mRNA and MUC5AC mRNA were examined by reverse transcriptase-polymerase chain reaction (RT-PCR). The protein expression changes of Duox1,HO-1,p-EGFR and EGFR were measured by Western blot,while the protein of MUC5AC in supernate and endochylema were detected by enzyme-linked immunosorbent assay (ELISA). Results The expression levels of MUC5AC mRNA and its protein in supernate liquid and endochylema in the CSE group were (0.660?0.044),(62.80?6.85) ?g/mg and (157.00?3.26) ?g/mg,and those of EGFR were 0.596?0.061 and 0.620?0.051,both of them increased significantly (P0.05),while the protein of p-EGFR,the mRNA and protein of EGFR,Duox1 and MUC5AC increased significantly (P
