补阳还五汤对糖尿病肾病的临床疗效分析

目的:探讨分析补阳还五汤治疗糖尿病肾病的临床疗效。方法:将我院于2009年4月～2011年8月收治的96名糖尿病肾病患者随机分成对照组与实验组,对照组接受常规的西医治疗,实验组接受与对照组完全相同的西医治疗,另服用补阳还五汤,观察其临床疗效。结果:实验组显效16例,有效24例,无效8例,总有效率83.33%;对照组显效12例,有效20例,无效16例,总有效率66.67%;实验组治疗前后的尿微量蛋白差值大于对照组,两组患者的差值比较有显著性差异(P0.05),实验组的治疗效果明显优于对照组。结论:补阳还五汤治疗糖尿病肾病有较好的临床疗效,值得推广。     

溶栓后转运PCI:降低中国农村急性心肌梗死的病死率

中国农村急性心肌梗死(AMI)的病死率逐年增加,已超越城市。县级医院溶栓和溶栓后转运经皮冠状动脉介入治疗(PCI)是救治ST段抬高型心肌梗死患者的利器。建立区域性基层医院溶栓后转运PCI紧急救治体系,有望降低中国AMI病死率。     

湖北省急性ST段抬高型心肌梗死溶栓治疗专家建议

<正>急性心肌梗死是由于冠状动脉(冠脉)粥样硬化或栓塞、炎症、痉挛导致的冠脉管腔严重狭窄和心肌供血不足引起的急性心肌缺血性坏死,极易导致猝死、恶性心律失常、急性心力衰竭或心源性休克等严重并发症。通常认为急性ST段抬高型心肌梗死(ST-segment elevation myocardial infarction,STEMI)意味着冠脉完全闭塞。早期积极进行再灌注,即溶栓或直接经皮冠脉介入治疗(percutaneous     

蚌埠市一般人群艾滋病知识知晓率调查分析

目的了解蚌埠市乡镇及城市社区居民艾滋病知识和相关态度的知晓情况,为进一步有针对性地开展艾滋病健康教育提供依据。方法通过分层随机抽样,于2007年7月对蚌埠市余庆街社区、同乐园社区、向前社区、小蚌埠镇、李楼乡、吴小街镇共600名居民进行艾滋病知识的问卷调查。结果城乡居民的总知晓率73.00%,农村居民艾滋病知识平均知晓率65.75%,城市居民79.51%,文化程度越高,艾滋病基础知识的知晓率越高。结论要继续加大尤其是农村居民的艾滋病相关知识宣传力度,消除歧视及恐惧;采用新闻、报刊与专题报道等群众乐意接受的宣传方式。     

Angiogenic Potency of Bone Marrow Stromal Cells Improved by ex Vivo Hypoxia Prestimulation

Summary: To study the angiogenic potency of hypoxia-prestimulated bone marrow stromal cells(BMSCs) when transplanted into acute myocardial infarction models of rats. BMSCs were cultured under hypoxia condition for 24 h. Their expression of VEGF was investigated. The rat acute myocardial infarction models were made by coronary artery ligation and divided into 3 groups at random.In normoxia group, twice-passaged BMSCs were labeled with Bromodeoxyuridine (BrdU) and then implanted into the infarction regions and ischemic border of the recipients in 4 weeks. The rats in hypoxia group were implanted with hypoxia-prestimulated BMSCs. In control group, the model rats received only DMEM medium injection. Six-weeks after AMI, the infarction regions were examined to identify the angiogenesis and the expression of the VEGF. Our results showed that viable cells labeled with BrdU could be identified in the host hearts. The infarction regions in normoxia and hypoxia groups had a greater capillary density and increased VEGF expression than the regions in control group. The capillary density and VEGF expression in hypoxia group were higher than in normoxia group. It is concluded that the enhanced expression of VEGF in BMSCs could be induced by ex vivo hypoxia stimulation. BMSCs implantation promoted the angiogenesis in myocardial infarction tissue via supplying exogenic VEGF. Angiogenic potency of bone marrow stromal cells was improved by ex vivo hypoxia prestimulation though the enhanced VEGF expression.     

支气管哮喘发病机制中肺炎衣原体作用的初步研究

目的：探讨肺炎衣原体感染在支气管哮喘发病机制中作用。方法：60例支气管哮喘患者，分别于其急性期和慢性期用酶联免疫吸附试验（ELISA）和巢式聚合酶链反应（nested-PCR)分别测定其血清肺炎衣原体（Cpn）IgM和和咽拭子标本中特异DNA片段。60例非哮喘者作为对照组。结果：急性期哮喘患者Cpn－IgM阳性率（60％）与慢性期（61．7％）和非哮喘组（55％）三者之间无显著性差异。急性期哮喘患者Cpn-nested-PCR阳性率（78．3％）与慢性期（33．3％）和非哮喘组（15．0％）之间有显著性差异。其中哮喘急性期与慢性期，急性期与非哮喘组，慢性期与非哮喘组之间均有显著性差异。结论：哮喘患者与非哮喘者的血清流行病学Cpn－IgM是一致的，但哮喘患者呼吸道内肺炎衣原体特异性DNA较非哮喘者阳性率高，可能呼吸道局部肺炎衣原体难以清除是引起支气管哮喘加重的重要原因。     

腋臭的整形外科治疗探讨

腋臭的治疗方法分为手术治疗和非手术治疗,以手术治疗方法疗效确切、彻底。传统的腋臭切除术,大多采用腋毛区的梭形切口,通过切除局部皮肤附件达到治疗的目的。临床实践证明,此方法有较大的局限性,如切除范围过小,手术不彻底,达不到根治的目的;切除范围过大,切口缝合困难,影响切口愈合;若腋毛区较宽大,手术难度更大,且愈合后可能因瘢痕增生挛缩导致上肢外展、上举功能受限。我们将整形外科的治疗原则和方法引入腋臭的治疗,克服了传统手术治疗的弊端,取得满意的疗效。
