Meta analysis of the relationship between human papilloma virus and nasal inverted papilloma / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To evaluate the relationship between human papilloma virus (HPV) infection and the occurrence, recurrence and malignant transformation of nasal inverted papilloma (NIP).@*METHOD@#With comprehensive retrieval of related literature that had been published in databases included Pubmed (1990--2011), Cochrane Library, CNKI (1979-2011), VIP (1989-2011), CBM (1990-2011) and WANFANG Meta-analysis software Rev-Man 5.0 was used to analyze the raw data and to calculate the value of combined odd ratio (OR) and 95% confidence interval (CI).@*RESULT@#According to Meta-analysis, the occurrence group between HPV and NIP, the OR was 34.44 and 95% CI was 12.96-91.56; the recurrence group, the OR was 3.66 and 95% CI was 1.77-7.56, to the high-risk HPV, the OR was 1.94 and 95% CI was 0.30-12.58; the malignant transformation group, the OR was 1.79 and 95% CI was 0.94-3.40 to the high-risk HPV, the OR was 49.35 and 95% (CI was 0.45-11.23.@*CONCLUSION@#HPV may play an important role in the occurrence and recurrence of NIP and high-risk HPV was closely related to the progress of NIP.

Effects of Compound Xueniaoting metabolized by liver microsomeson glomerular mesangial cells / 中草药

Objective To study the mechanism of traditional Chinese medicine Compound Xueniaoting (CXNT) in treating glomerulus diseases with the main pathological changes of proliferation in mesangial cells. Methods CXNT and rat liver microsomes were incubated together, and then the incubated CXNT was added into cultured glomerular mesangial cells (GMC) in vitro. The proliferation of GMC was observed by MTT assay, the levels of interleukin-6 (IL-6) and endothelin-1 (ET-1) were determined by radioimmunoassay, and content of lactic dehydrogenase (LDH) was determined by velocity assay. ResultsCXNT (2, 4, 8 mg/mL) metobolized by rat liver microsomes could all inhibite the proliferation of GMC and production of IL-6 and ET-1 in a dose-dependent manner. Conclusion CXNT can inhibite the proliferation of GMC and restrain the secretion of IL-6 and ET-1, this function may be one of CXNT mechanisms in treating some mesangial proliferative glomerulonephritis.
