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.

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

Objective To assess the effect and safety of lanthanum carbonate vs conventional phosphate binders for hyperphosphatemia in patients undergoing maintenance hemodialysis.Methods According to the collaborative search strategy,MEDLINE (1996 to 2012.12),EBCO (1996 to 2012.12),the clinical control test database of Cochrane Library and Chinese Wanfang database (1996to 2012.12) were searched.Related literature,whether Published or not and meeting summary included,were searched by hand.Quality assessment and data extraction were conducted by two independent investigators.Meta-analysis was conducted by RevMan 5.0.The following outcomes were assessed:serum phosphorus levels,serum iPTH levels,serum calcium levels and adverse events.Results were expressed as OR with 95％ confidence interval for dichotomous outcomes and WMD with 95％ confidence interval for continuous outcomes.Results A total of 10 reports were identified which met the inclusion criteria.The meta-analysis showed that the efficacy of treating hyperparathyroidism in hemodialysis patients was similar between lanthanum carbonate and conventional phosphate binders (WMD =-0.06,95％ CI-0.27 to 0.15,P =0.57) and the incidences of discontinuing due to adverse events were also similar.However,there were fewer hypercalcemic episodes and lower serum calcium levels in the lanthanum carbonate group compared to calcium-based phosphorus binders group.Conclusion Lanthanum carbonate is effective and well tolerated in treating hyperphosphatemia in hemodialysis patients with fewer hypercalcemia and lower serum calcium levels compared to calciumbased phosphate binders.

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 provide reference for the establishment of quality standard for Jinbo capsule. METHODS:TLC was conducted for the qualitative identification of Phellodendron chinense and Melia toosendan in preparation;HPLC was used for the content determination of berberine hydrochloride in preparation;the column was Diamonsil C18 with mobile phase of acetoni-trile-0.1% phosphoric acid (50∶50,V/V) at flow rate of 1 ml/min,detection wavelength was 265 nm,column temperature was 25 ℃ and volume injection was 10 μl. RESULTS:TLC spots of P. chinense and M. toosendan in preparation were clear and well-separated. The linear range of berberine hydrochloride was 0.044-0.154 mg/ml(r=0.999 9);RSDs of precision,reproducibili-ty and stability tests were no more than 2.0%,recovery was 98.36%-102.15%(RSD=1.11%,n=9).

Objective: To study the scutellaria and coptis in different proportions, the main active ingredient of baicalin, berberine dissolution rate changes and to explore the effect of traditional drug pair of scutellaria and coptis on the dissolution rate of active ingredient. Methods: Based on the clinic common used prescriptions of scutellaria with coptis, ratio of 1:0,1:1,1:2,1:3,2:1,2:3,3:1,3:2,0:1 was selected, after the water boiling reflux extraction, refining separation, various products were obtained for the test, under the optimized conditions of RP-HPLC analysis to compare chromatographic fingerprints and to examine the main component baicalin, berberine in aspects of relative peak area ratio of changes and compatibility relations. Results: Compatibility of Scutellaria baicalensis and Coptis at different proportions can influence the dissolution rate of baicalin, Berberine Hydrochloride. There was a non-linear relationship of dissolution rate of baicalin and Scutellaria baicalensis. The best ratio of scutellaria ratio was 3:1, the best compatibility ratio of coptis was 1:3. Conclusion: Different compatibility proportions of scutellaria and coptis will result in different dissolution rate of baicalin and berberine.

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.
