发热门诊过氧化氢空气消毒效果研究

目的观察过氧化氢消毒剂气溶胶喷雾和普通喷壶喷雾对医院发热门诊空气细菌杀灭效果。方法对发热门诊空气中菌落数进行消毒前和消毒后监测。结果3％过氧化氢用普通喷壶喷雾后60min，平均细菌杀灭率仅为3．04％；气溶胶喷雾器喷雾后60min，平均细菌杀灭率为87．31％，差异显著。结论过氧化氢消毒剂气溶胶喷雾作用30～60min即可达到可靠的消毒效果；此方法省时、省力、方便、易行；杀菌效果明显高于普通喷壶喷雾，且节约药物。     

Catastrophic Periprosthetic Osteolysis in Total Hip Arthroplasty at 20 Years: A Case Report and Literature Review

BackgroundPeriprosthetic osteolysis is a serious complication following total hip arthroplasty (THA). However, most orthopedic surgeons only focus on bone loss and hip reconstruction. Thus, it was required to understand the treatment algorithm for periprosthetic osteolysis integrally.Case PresentationA 52‐year‐old Asian male presented with chronic hip pain. A mass appeared on the medial side of the proximal left thigh at more than 20 years after bilateral THA. Radiographs revealed catastrophic periprosthetic osteolysis, especially on the acetabular side. Large amounts of necrotic tissue and bloody fluids were thoroughly debrided during revision THA. A modular hemipelvic prosthesis was used for revision of the left hip. Four years later, the patient presented with right hip pain, where a mass appeared on the medial side of the proximal right thigh. A primary acetabular implant with augment was used for revision of the right hip. Laboratory evaluation of bloody fluid retrieved from surgery revealed elevated levels of inflammatory markers.ConclusionInflammatory responses to polyethylene wear debris can lead to severe bone resorption and aseptic loosening in the long‐term following THA. Therefore, in spite of revision THA, interrupting the cascade inflammatory might be the treatment principle for periprosthetic osteolysis.     

黄芪精口服液对围生期心肌病患者心功能不全及辅助T细胞调节作用的研究

[摘要]目的探讨中药黄芪精口服液对围生期心肌病患者心功能不全及辅助T细胞的调节作用。方法36例围生期心肌病住院患者随机分为常规治疗对照组与加用黄芪精口服液治疗组,治疗8周后应用超声心动图观察患者心功能,检测心功能不全实验室相关指标N末端脑钠肽前体（NT—proBNP）及免疫相关指标IFN-γ、IL-2、IL-4、IL-10并进行疗效的比较。结果治疗8周后2组心率、左室收缩末内径和左室舒张末内径均较治疗前显著减小（P均〈0．05）,左室射血分数、左室短轴缩短率、每搏量和心排血量较治疗前显著提高（P均〈0．05）,以上各项指标治疗组均较对照组改善明显（P均〈0．05）;NT-proBNP在治疗8周后2组皆有显著下降,治疗组下降更显著（P〈0．05）;血清IFN-γ和IL-2明显降低,IL-4和IL-10水平明显升高。结论黄芪精口服液配合常规治疗围生期心肌病患者可以显著改善心功能,提高治疗效果,并使辅助T细胞的平衡从Th1向Th2移动。
