ABSTRACT
ObjectiveTo explore the clinical efficacy and safety of autologous peripheral blood stem cell transplantation(APBSCT) in the treatment of pemphigus.MethodsTotally,3 patients with pemphigus vulgaris who responsed poorly to 6-month treatment with glucocorticoids or immunosuppressants or experienced aggrevation of disease and developed treatment-related complications,received APBSCT and were followed up for more than 5 years.There were 1 male and 2 females with an average age of 27.3(21-39) years.The mobilization program included cyclophosphamide (CTX) 4 g/m2,recombinant human granulocyte colonystimulating factors(G-CSF) and Rituximab 375 mg/m2,and the preconditioning regimen included intravenous CTX (50 mg/kg per day on days -6,-5,-4,-3),antithymocyte globulin at 2.5 mg/kg per day(on days -3,-2,-1 and 0) and Rituximab (600 mg/d on days 0 and 7).ResultsAll the 3.patients were successfully engrafted.The mean time for peripheral reconstruction:white blood cells 13.3 days (from day 11 to 16),platelet 16.3 days (from day 16 to 17).Monitoring of immunity indices and related antibodies showed no abnormality and the immune system was well reconstructed.No serious complications occurred during the follow up,and the patients' quality of life was obviously improved.ConclusionAPBSCT may be an effective and safe option for the treatment of pemphigus.
ABSTRACT
The study aims to investigate the incidence of bacterial vaginitis(BV) in female patients with condyloma acuminatum. In eighty-seven female patients with condyloma acuminatum, the incidence of BV was 37.93%. The incidence of relapse of condyloma acuminatum was markedly higher in patients with complication of BV compared with those without BV. The results suggested that vaginal infection may contribute to relapse of condyloma acuminatum.
ABSTRACT
Objective To express the unique gene of herpes simplex virus type 2(HSV-2) gG-2(gG-2T) in E.coli BL21,and study preliminarily the lemologic characteristics of gG-2T protein. Methods We cloned the gene of gG-2T and had gG-2T fusion protein expressed in E.coli BL21,and identified its activity by Western blot and indirect ELISA.Results Glycoprotein G-2T fusion protein could combine with GST polyclonal antibody through gG-2T fusion protein expressed in prokaryotic system and SDS-PAGE had a specific binding strap in 46 ku nearby.The gG-2T fusion protein could react with HSV-2 patients' serum,but not with HSV-1 patients' serum and r-Globulin.Conclusion We obtained gG-2T fusion protein,which can combine with GST polyclonal antibody and react with HSV-2 patients' serum specifically.It will provide an experimental basis for diagnostic kit and vaccine of gG-2 protein target area.
ABSTRACT
To investigate the Th1/Th2 profile in peripheral blood of patients suffering from condyloma acuminatum (CA) with or without genital herpes. The levels of the intracellular cytokines (IFN ? and IL 4) of CD4 + T lymphocytes of peripheral blood were assayed by flow cytometry in 35 patients with CA (among them 15 patients were complicated by genital herpes) and 20 healthy volunteers as controls. The results showed that all the patients with CA had significantly higher percentage of Th2 cells and lower percentage of Th1 cells compared with heathy controls( P
