Background: Folium Hibisci Mutabilis was one of the traditional Chinese medicines with pharmacological activities of wound healing,antibacterial and anti-inflammatory, normally applied to the clinical treatment of local purulent infection, scald, and epidemic parotitis.However,f ew people reported that its effects of extracts on RAW264.7, cells and TNF-α, IL-6, and NO levels in rats serum of inflammation rats.Materials and Methods: We mainly adopted the RAW264.7, macrophage cell line which was intervened by lipopolysaccharide (L PS), to establish the model of inflammatory cells.The secretion changes of TNF, and IL-6, level in the model cell acted by the FHMAEs, were detected by ELISA, NO level changes were determined by nitrate reductase method;Arthritis model induced by Collagen Type Ⅱ were chose, and regulatory role of FHMAEs on IL-6 and NO level in serum were observed, FHMAEs mechanism of action were investigated in the treatment of rheumatoid arthritis.The states of the model rats were recorded.Results: Release of TNF-α, IL-6, and NO in LPS-induced RAW264.7, cells were significantly inhibited and has a clear dose-response relationship;The TNF-α , IL-6 and NO levels were reduced by FHMAEs in experimental arthritis rats serum, and the status of rats were improved.At last, we found that IL-6, NO and TNF-α levels in the inflammatory cells could be reduced by FHMAEs greatly.Conclusion: Both synovial inflammation and synovial proliferation could be reduced or inhibited by FH MAEs, all of this may provide experimental effective data for the novel drugs development and the clinical treatment of rheumatoid arthritis.

本文探讨了无创方法治疗严重压疮合并坏死性筋膜炎的病例报道，使用滴注疗法外加负压吸引技术可以有效地缩短创面愈合时间，并且减少压疮的复发，而且创面愈合后的外观良好。因此。这种方法对于破溃创面下存在交通腔隙的压疮有着良好的疗效。并且对于全身无法耐受手术的压疮合并坏死性筋膜炎的患者也有优秀的表现。

淋巴水肿仍被认为是难以解决的问题.目前,临床对癌症的诊断越来敏感,早期手术干预越发普遍,随之而来的癌症术后淋巴水肿的发病率较前大幅升高,导致淋巴水肿的患者增加.随着科技发展,尤其超显微外科的提出,使淋巴管、静脉吻合成为可能,以致早期淋巴水肿的临床症状得以明显改善.本文旨在探讨新近有关淋巴水肿的研究进展,以帮助深入了解,并为根据个体差异制定综合预防和诊疗方案.
目的：探讨乳腺癌根治术后上肢淋巴水肿的治疗方法.方法：对6例乳腺癌根治术后上肢淋巴水肿患者进行超显微淋巴管-静脉吻合术,对比术前、术后上肢容积差异及消肿率.结果：6例患者患肢肿胀程度明显减轻及胀痛感消失,Campisi标准评价疗效均获优良.结论：超显微外科治疗乳腺癌术后上肢淋巴水肿手术创伤小,效果显著.
