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.

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 investigate the clinical effect of Zhengtian Pills on blood-stasis pattern of migraine with hemodynamics and TCD as markers. Methods: 30 patients with blood-stasis pattern of migraine were given drug Zhengtian Pills for a month. The hemodynamic marker, integrating value of nail fold microcirculation and TCD before and after treatment were compared. Results: There were significant differences in hemodynamic marker, integrating value of nail fold microcirculation and TCD between before and after treatment (P

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.

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 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.

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.
