基于现代文献的放血疗法疾病谱研究

目的归纳放血疗法近10年的临床研究文献,总结放血疗法疾病谱。方法计算机检索中国知网(CNKI)、维普数据库(VIP)、万方数据库(WANFANG DATA)、PubMed、Cochrane library中有关放血疗法的临床研究文献,各数据库检索时间从2009年1月1日起至2019年2月28日。经阅读筛选后记录每篇文献的病症名,统计各病种文献量,并对各病症系统进行分类总结。结果共纳入文献4288篇,涉及疾病349种,分布于17个系统,其中文献最多的前10种疾病依次是带状疱疹(394)、痤疮(321)、脑血管病(包括出血性、缺血性及其并发症和后遗症,247)、周围性面瘫(218)、痛风性关节炎(183)、带状疱疹后遗神经痛(164)、颈椎病(162)、腰椎间盘突出症(161)、膝骨性关节炎(136)、偏头痛(121)。这些疾病的文献量均≥100,共计2107篇,约占文献总数的49.14%。结论放血疗法的适应症广泛,但优势病种相对集中,主要为神经系统疾病。     

Evozierte Potenziale

Evoked potentials (EP, acoustic AEP, somatosensory SEP, visual VEP) and the magnetically evoked motor potentials (MEP) measure the conduction time in the respective conduction path. The importance of the EP lies in the detection of a demyelinating type of lesion or dysfunction and thus in the diagnosis and prognosis of multiple sclerosis.     

全瓷桩核的初步临床比较研究

目的 比较全瓷桩核与金属桩核的临床适应证与修复效果。方法 分别制作全瓷桩核 铸造全瓷冠、桥，金属桩核 金属烤瓷冠、桥，天然牙 铸造全瓷冠、桥各50个，比较三者的适应范围，用Shade eye电脑比色仪测定、比较三者的Shade值，临床复查修复体的颜色、松动脱落与折裂折断情况。结果 全瓷桩核 铸造全瓷冠桥与金属桩核修 金属烤瓷冠桥在颜色上有差异，与天然牙 全瓷冠桥无差异；全瓷桩核的折断率与金属桩核无统计学差异，但全瓷桩核在临床上有严格的适应证。结论 全瓷桩核有良好的美学效果和较好的强度。     

New horizontal v-shaped osteotomy for correction of protrusion of the zygoma and the zygomatic arch in East Asians: indication and results

Protrusion of the zygoma is commonly considered undesirable and unattractive among East-Asians, and many try to achieve a harmonious oval midface by having various cosmetic operations. However, effective contouring for a severe protruding zygoma has rarely been reported .The objectives of this study therefore were to investigate the feasibility and effectiveness of a horizontal V-shaped ostectomy for correction of protrusion of the zygoma and zygomatic arch, and to discuss its indications. From January 2008 to December 2011 we treated 27 patients by contouring of the zygoma with a horizontal V-shaped ostectomy through intraoral and preauricular incisions. The effectiveness was then evaluated with cephalometric radiographs, 3-dimensional computed tomography, and standard facial photographs taken before and after operation. The postoperative appearance of all 27 patients showed that the protrusion had been effectively reduced with no serious complications, and the facial contour had improved. The ?nal aesthetic outcomes were satisfactory for both surgeons and patients. The horizontal V-shaped osteotomy is a good technique for the reduction of protrusion of the zygoma and zygomatic arch, and it has the advantages of more convenient multishifting, better results, and fewer complications. It also ensures the integrity of the structure of the malar complex.

手辅助腹腔镜手术在胃肠外科中的应用及适应证选择

尽管传统腹腔镜技术在胃肠道良恶性疾病中的应用逐步获得广泛的认可,但仍有学习曲线延长、手术时间延长、技术难度增加以及肥胖患者手术复杂性等不足。手辅助腹腔镜技术（HALS）作为介于开腹手术与腹腔镜手术的一种杂交技术．由于恢复了手的触觉以及手眼协调．弥补了传统腹腔镜手术的不足．同时部分保留了传统腹腔镜手术的微创优势,且手术时间及学习曲线明显缩短．在肥胖患者及复杂的胃肠手术中具有一定优势。但HALS手术也存在手对术野的阻挡和手疲劳等不足．HALS治疗恶性肿瘤的近远期疗效尚待更多的循证学研究加以证实。
