Expression of BATF, a member of the activator protein-1 family, in renal tissues of MRL/lpr mice / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the expression of BATF, a member of the activator protein-1 family, in the renal tissues of mice with lupus nephritis.</p><p><b>METHODS</b>The renal tissues from 24-week-old female MRL/lpr mice and age- and sex-matched C57BL/6 mice were examined for BATF protein expressions using Western blotting and for expressions of BATF, RORγt and IL-17A mRNA using quantitative real-time PCR. The results of laboratory examinations were analyzed in relation with the histopathology of the mice.</p><p><b>RESULTS</b>The urinary protein and ds-DNA levels were significantly higher in MRL/lpr mice than in the control mice (P<0.05). Compared to normal control mice, MRL/lpr mice showed obvious glomerular fibrosis and inflammatory cell infiltrating with significantly increased BATF protein and mRNA expressions (P<0.05) and RORγt and IL-17 mRNA expressions in the renal tissues (P<0.05). In MRL/lpr mice, the expression of BATF mRNA was positively correlated with the RORγt and IL-17A mRNA expressions in the renal tissues.</p><p><b>CONCLUSION</b>The renal expressions of BATF protein and mRNA is increased in MRL/lpr mice. BATF may participate in the immunopathogenesis of lupus nephritis by enhancing Thl7 cell response.</p>

Autologous peripheral blood hematopoietic stem cell transplantation in the treatment of three cases of severe pemphigus / 中华皮肤科杂志

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.

Concept of professional socialization in nursing

Each nursing student comes to nursing with a lay image of nursing portrayed by nurses they have seen. This lay perception of nursing that a nursing student holds is transformed to a more professional understanding that is acquired in nursing schools. This process is known as professional socialization. It is a process of learning the norms, attitudes, behaviours, skills, roles, and values of the profession. It involves the internalization of the values and norms of the profession in the individual’s own behaviour and self-concept. The ultimate goal of professional socialization is to internalize a professional identity of the profession. Professional socialization sets in to reduce the tension from the scenario of reality shock and facilitate adaptation during the transition process. This paper serves as a concept paper with the main purpose of introducing and explaining the concept of professional socialization in nursing to help the readers in gaining further understanding of the concept, especially within the local context. The first author has also incorporated her own personal reflections with regards to her socialization process to nursing.

Expression of CD34 and Platelet Derived Growth Factor Receptor 尾 and Pattern of DNA Ploidy in Dermatofibrosarcoma Protuberans / 中华皮肤科杂志

Objective To investigate expression of CD34 and platelet derived growth factor receptor ? (PDGFR-?) and pattern of DNA ploidy in dermatofibrosarcoma protuberans (DFSP), and to study their significance and relationship. Methods The expression of CD34 and PDGFR-? was detected by immunohistochemical SP method in paraffin-embedded specimens from 39 DFSPs and 30 dermatofibromas (DFs). The findings were quantitatively analyzed by image system. The pattern of DNA ploidy was detected by flow cytometry. Results The expression of CD34 and PDGFR-? in the DFSPs was higher than that in the DFs (P
