Objective To systematic review the clinical efficacy and safety of infliximab in treatment of severe alcoholic hepatitis (SAH).Methods The electronic database of PubMed,EMbase,Web of Science,OVID and Cochrane systematic review database,CBM disc and CNKI from building the database until March 2013 were retrieved.With SAH,severe alcoholic hepatitis,infliximab and tumor necrosis factor as key words or free words.Randomized-controlled trials (RCT) on infliximab in treatment of SAH was selected and analyzed by Meta analysis.Results Two RCTs was enrolled,included 56 SAH patients.Infliximab (10 mg/kg) combined with glucocorticoids (40 mg/d) might accelerate death because of the high prevalence of serious infections.Infliximab (5 mg/kg) combined glucocorticoids (40 mg/d) had more tolerability and improved patient's Maddrey scores significantly.Conclusions Existing clinical evidence suggest that it is short of evidence for the clinical efficacy and safety of infliximab.It need guide by large sample of clinically and different doses RCT.

Objective To observe the curative effect of Shenshuai Pellet on chronic renal failure patient and its influence on hemoglobin, blood plasma albumin and blood rheology. Methods 60 cases of chronic renal failure patients were randomly divided into the treatment group and control group. On the basis of high quality low-protein low-phosphorus diet, envies the vegetable protein, correction water and electrolyte balance, the acidosis and so on, the control group was treated with Oxyamyli tectus Aldehydum, the treatment group was given Shenshuai Pellet orally. Results Total effectiveness of treatment group and control group was 90% and 60% respectively. The clinical symptoms of treatment group were obviously improved. In addition, the hemoglobin, blood plasma albumin and the blood rheology of treatment group were significantly improved compared with control group (P

To construct an HSV-1 vector vaccine carrying HIV-1 antigens, HIV-1 gp160, gag, protease and the expression elements were chained together, and then inserted into the internal inverted repeat sequence region of HSV-1 by bacterial artificial chromosome technology. Firstly, HIV-1 gp160 (including type B and C), gag and protease genes were cloned into pcDNA3 in series to generate the pcDNA/gBgp and pcDNA/gCgp, then the recombinant plasmids were transfected into 293FT cells, and HIV-1 antigen was detected from transfected cells by Western blotting. Then the expression cassettes from pcDNA/gBgp and pcDNA/gCgp, comprising HIV-1 antigen genes and expression elements, were cloned into pKO5/BN to generate the shuttle plasmids pKO5/BN/gBgp and pKO5/BN/gCgp. The shuttle plasmids were electroporated into E. coli cells that harbor an HSV-BAC, the recombinant bacteria were screened, and the recombinant DNA was extracted and transfected into Vero cells. The recombinant virus was purified through picking plaques, the virus' DNAs were identified by Southern blotting; HIV-1 antigen was detected from the recombinant HSV-1 infected cells by Western blotting, and the virus' replication competent was analyzed. As the results, gp160 and gag proteins were detected from 293FT cells transfected with pcDNA/gBgp and pcDNA/gCgp by Western blotting. The recombinant bacteria were generated from the E. coli electroporated with pKO5/BN/gBgp or pKO5/BN/gCgp. The recombinant HSV was purified from the Vero cells transfected with the recombinant DNA, the unique DNA fragment was detected from the genome of recombination HSV by Southern blotting; gp120 and gp41 were detected from the infected cells by Western blotting, and the recombinant HSV retained replication competent in mammalian cells. The results indicate that the recombinant HSV carrying HIV-1 gp160, gag and protease genes was generated, the virus retains replication competent in mammalian cells, and could be used as a replicated viral vector vaccine.

Objective To evaluate right ventricular function of chronic thromboembolic pulmonary hypertension (CTEPH) patients by echocardiography and cardiac magnetic resonance (CMR),and to evaluate the value of clinical application of those right heart function indexes.Methods 32 patients with CTEPH who underwent CMR and echocardiography were involved in the study.Right ventricular index of myocardial performance (RIMP),fractional area change (FAC),tricuspid annular plane systolic excursion (TAPSE) and tissue Doppler-derived tricuspid lateral annular systolic velocity (S') were measured by echocardiography.Right ventricular end-diastolic volume (RVEDV) and end-systolic volume (RVESV) were measured by cardiac magnetic resonance and right ventricular ejection fraction (RVEF) was calculated.Results A positive correlation was found between FAC and RVEF (r =0.423,P =0.022),there was a negative correlation between RIMP and RVEF (r =-0.387,P =0.048),there was no correlation between TAPSE and RVEF (r =0.451,P =0.22),a positive correlation was found between S' and RVEF (r =0.689,P =0.000).Conclusions The echocardiographic parameters FAC,RIMP and S' can reflect right ventricular function in patients with CTEPH and can be used as a routine clinical parameters.

Objective To evaluate right ventricular systolic function in patients with pulmonary hypertension (PH) by real-time three-dimensional echocardiography (RT-3DE),and compared with cardiac magnetic resonance.Methods A total of 23 patients with PH who underwent MRI and echocardiography in the study.Right ventricular index of myocardial performance (RIMP),fractional area change (RVFAC),tricuspid annular plane systolic excursion (TAPSE) and tissue Doppler-derived tricuspid lateral annular systolic velocity (S') were measured by echocardiography.RV end-diastolic volume (RVEDV) and endsystolic volume (RVESV) were measured by RT-3DE and cardiac magnetic resonance and RV ejection fraction (RVEF) was calculated.Results A positive correlation was found between RVFAC and RVEF (r =0.595,P =0.003),there was a negative correlation between RIMP and RVEF (r =-0.745,P =0.000),has no correlation between TAPSE and RVEF (r =-0.029,P =0.896),a positive correlation was found between S' and RVEF (r =0.489,P =0.018).There were close correlation between RVEDV,RVESV and RVEF measured by RT-3DE and MRI (P ＜0.001,respectively);Bland-Altman analyses showed good agreement between them.Conclusions RT-3DE can noninvasive,accurate assessment right ventricular systolic function in patients with PH,and provide prognosis and treatment choice for clinical demands.

Objective To detect the changes in the expression of discoidin domain receptor 2(DDR2)and matrix metalloproteinase (MMP)-13 in different stages of cartilage and synovium damage of osteoarthritis rats.The relation between DDR2 and the degree of cartilage damage was explored.Methods Modified papain knee joint injection approach was adopted to establish animal model of OA.The expression and distribution of protein of DDR2 and MMP-13 were checked in articular cartilage and synovium at different stages of OA.Results The expressions of DDR2 in articular cartilage and synovium of experimental groups were different from those of the normal group (P＜0.01).They were higher in cartilage than those in the corresponding synovium.The expressions of MMP-13 demonstrated the same characteristics with those of DDR2,r=0.93(P＜0.01).Conclusions The important role of DDR2-MMP-13 in cartilage damage has been proven in the pathogenic process of OA.The upregulated expressions of DDR2 in articular cartilage and synovium have a detrimental effect on cartilage degeneration.

Objective To evaluate the application value of dermoscopy in the diagnosis of genital condyloma acuminatum (CA) in men.Methods A total of 122 warts from 66 male patients with suspected genital CA were firstly diagnosed by experienced dermatologists according to macroscopic morphological characteristics of lesions and clinical history of patients.Afterwards,the warts were examined and diagnosed by dermoscopy,and the two diagnosis results were compared with histopathological findings.Results Of 122 suspected warts,100 were diagnosed as CA by naked-eye examination,112 as CA by dermoscopy and 114 as CA by pathological examination.When histopathological findings served as the gold standard,dermoscopy had a sensitivity of 97.4％ and a specificity of 87.5％,and naked-eye examination had a sensitivity of 87.7％ and a specificity of 100％.Under dermoscopy,most male genital warts were pink (98/114,86.0％) and papillary (98/114,86.0％),and had distinct vascular characteristics (107/114,95.5％),which mainly included pleomorphic vessels (102/114,89.5％) and punctate vessels (98/114,86.0％).Conclusion CA has characteristic structures under dermoscopy,so dermoscopy can be used for the diagnosis of genital CA in men.
