伴严重增殖性玻璃体视网膜病变视网膜脱离的玻璃体手术及失败原因探讨

本文报导采用现代玻璃体手术结合巩膜扣带、空气或硅油填塞治疗81例伴严重增殖性玻璃体视网膜病变(PVR)视网膜脱离的手术效果.经过6～28个月(平均14个月)的随访,视网膜完全平伏者54例,成功率66.7%,对极严重的PVR D(?)(闭斗状脱离)也取得50%的成功率.硅油填塞初步应用于极严重病例尤其是巨大裂孔的治疗,取得明显的效果.本文病例术后视力提高者50例,不变19例,下降12例,术后视力在0.05以上者共34例.认为玻璃体手术结合其它技术是伴严重PVR手术治疗的有效方法,提出进一步提高PVR治疗成功率的方法:彻底清除增殖膜及寻找一种有效抑制膜增殖而对眼内其它组织无毒性的药物。指出旧的PVR分级法存在的不足,推荐用于硅油研究的PVR新的分级法.     

从专利文献看创伤敷料的发展概况

创伤,包括切口伤和烧伤等,是最常见的疾病之一。治疗时,在创面上复盖上一层敷料,既可以防止细菌侵入,又可控制渗出液流失。在植皮区和供皮区用敷料复盖,有利肉芽组织的增生,加速上皮组织的愈合。目前,使用最多是的棉质敷料,但它容易粘连伤口,并易滋生细菌。因此,长期以来人们就想研究一种材料来源广、使用方便、对伤口有保护治疗作用的敷料。本文仅从专利文献方面,介绍近10年来国内外这方面研究概况。     

闭式引流在甲状腺外科的临床应用

甲状腺手术虽不断改进和提高,但手术并发症仍较多,国内报告约5.7～9.7%,其中术后出血和血肿达0.6～1%。而且因术后血肿压迫导致急性窒息死亡者时有报告。预防术后出血和血肿的发生除术中妥善止血外,非常重要的是术后充分引流。只要充分引流就绝无血肿发生,更不会

名老中医张天健治疗脊髓型颈椎病的经验

脊髓型颈椎病是骨伤科疑难病之一，由于非手术治疗一般收效徽且疗程长，牵引和按摩还有可能使症状加重，临床上常采用手术治疗。但又由于手术难度大，危险性高，患者不宜接受。张天健老师是著名的中医骨科专家，作者师承学习，受益非浅，从师2年期间，张老运用中药辨证治疗了23例症状尚轻或手术后效果不明显的脊髓型颈椎患者，收到较好疗效。现整理介绍如下。     

127例海军飞行员血液流变学指标及其与冠心病危险因素的相关分析

近年来冠心病等心血管疾病对飞行的影响特别突出，飞行员因冠心病的停飞率有增加趋势[1]。研究飞行员血液流变学指标及其与冠心病危险因素的关系，对探讨飞行员冠心病的防治及降低停飞率有重要的指导意义。现将2001年5月至2004年5月来我科疗养的127名海军飞行员的调查情况报告如下。     

重组2型腺相关病毒-转化生长因子β3对实验性肝纤维化大鼠肝脏组织病理学和Ⅰ型胶原表达的影响

Objective To investgate the effects of TGF β 3 on rat hepatic fibrosis. Methods The TGF β 3 cDNA was cloned into rAAV2 vector. Rats were randomly divided into four groups: normal control group, model group, negative control group and TGF β 3 group. Hepatic fibrosis was induced by hypodermic injection of 40% CCI4. Recombinant AAV2-TGF β 3 viral particles were injected via the vena caudalis one week before CCh treatment. Rats were executed 8 weeks after CCI4 treatment, global histological change was observed after HE staining, the distribution of the collagen fibers was observed after masson staining, his-tochemistry was done to observe the expression of collagen Ⅰ; The positive area rate of the collagen fibers and the average optical rate of collagen Ⅰ were quantified. Results HE staining indicated that collagen fibers were reduced in the TGF β 3 group. Masson staining shown that the collagen fibers were distributed around the blood vessel, in the portal area and disse space. Compared to the model group (13.2%±2.2%) and negative control group (12.3%±1.5%), the collagen fibers in liver tissues of TGF β3 group (7.7% ± 1.5%) were significantly decreased (q = 9.456, P < 0.01; q = 8.217, P < 0.01). Histochemistry indicated that the collagen fibers of liver tissues of TGF 15 3 group (0.185±0.033) were significantly higher than those in the model group (0.252±0.042) and the negative control group (0.230±0.029), (q = 6.228, P < 0.01; q = 4.346, P < 0.01). Conclusion TGF β 3 alleviates the damage to hepatic cell and the level offibrosis in CCI4 treated rats and inhibits the expression of collagen Ⅰ.
