实验小鼠肠道正常菌群

在动物肠道中栖息的细菌，构成了肠道正常菌群。实验动物的质量与肠道菌群的状态有着十分密切的联系，肠道菌群平衡状态在维持动物机体的生理状态、正常功能，以及抵抗外袭菌方面起着重要的作用。小鼠肠道中，每克肠内容物含有上亿个菌体，可分为10～15个属，上百个种。肠道正常菌群的主要菌属有双歧杆菌、拟杆菌(类杆菌)、肠球菌、乳杆菌、梭杆菌、真杆菌。不同品系的小鼠之间，各种菌的数量有所不同。本文简要介绍了近年来对小鼠肠道正常菌群的研究进展。     

神经生长因子基因转染联合强化铁营养防治豚鼠爆震性聋的实验研究

Objective To study the protective effects of adenovirus-mediated human beta-nerve growth factor gene (hNGFβ) transfer combined with iron fortified nutrition on blast hearing damage in guinea pigs. Methods Deafness was induced by blast (172dB SPL) in 35 healthy guinea pigs. Seven days after noise exposure, 10 guinea pigs were inoculated with adenovirus-mediated hNGFβ (Ad-hNGFβ) into the perilymphatic space (the gene group), another 10 guinea pigs were given hNGFβ combined with iron fortified nutritional diet (the combination group), still another 10 guinea pigs were inoculated with artificial perilymphatic fluid (APF), and 5 guinea pigs served as control, given neither medicine nor noise exposure. Auditory brainstem response (ABR) threshold shifts were monitored in the guinea pigs before blast exposure and after gene transfer. Changes in cochlear morphology were examined with immunohistochemical and HE staining. Results One week after successful inoculation of hNGFβ, it was noted that Ad-hNGFβ protein was expressed in each turn of the cochlea, and its intensity was almost equal. After gene transfer in the combination group and the gene group, ABR threshold shifts at week 1 and 4 were significantly smaller than those of the APF group. HE staining showed that the number of the spiral ganglion cells in the combination group and the Ad-hNGFβ group was significantly higher than that of the control group after 4 weeks (P<0.01). Conclusions Ad-hNGFβ combined with iron fortified nutritional diet was effective in the prevention and treatment of blast hearing damage of cochlear hair cells.     

精索扭转误诊24例分析

目的：分析精索扭转误诊的原因及教训，提高临床医生对该病的认识水平与警惕性，以减少误诊的发生。方法：对24例外院误诊的精索扭转病例进行回顾性分析。结果：24例患者均经手术证实为精索扭转，因未能及时诊断，延误时机而切除缺血坏死的睾丸。结论：彩色多普勒血流动态显像应作为诊断该疾病的常规与首选检查方法，对精索扭转一旦确诊或疑有精索扭转的患者应及早行紧急复位，以期挽救睾丸。同时行睾丸固定术也十分必要，对于确诊毫无保留价值的睾丸需行切除。     

简单灵敏的免疫复合物抗原特异性固相酶联检测法

本文将聚乙二醇(PEG)比浊法和固相酶联免疫法(ELISA)结合,建立了—较灵敏的免疫复合物(IC)直接固相吸附抗原特异性检测法。利用牛清蛋白(BSA)为已知抗原组份的IC模型,分别对IC直接固相吸附的条件和影响因素、方法的灵敏度、重复性等进行了研究。结果发现IC在解离状态下直接固相吸附后的抗原特异性检测灵敏度明显高于未解离者。该法具有简单易行,灵敏度较高、适于临床测定大量血清样品等优点。     

肾动脉狭窄支架植入术的临床疗效观察

目的探讨肾动脉狭窄支架植入术的临床疗效.方法1997年1月～2004年12月,我院行支架介入治疗肾动脉狭窄27例.对27例术前、术后及随访期内血压、肾功能以及生活质量进行评估,并与同期单纯药物治疗肾动脉狭窄27例进行比较.结果介入组27例植入支架40枚,手术成功24例(88.9%,24/27),失败3例(11.1%,3/27),手术并发症5例(18.5%,5/27).术后在血压下降(包括收缩压舒张压)肌酐下降,肾小球滤过率增加方面,介入组获益率明显优于药物组,两组比较差异均有显著性,术后随访6个月～8年6个月,中位数为1年9个月,介入组有19例能比较健康的生活和工作,药物组仅12例能维持生活和工作.结论支架介入治疗较单纯药物治疗肾动脉狭窄疗效显著.     

110例胃癌外科治疗分析

目的　探讨胃癌外科治疗的现状。方法　对我院 2002 年 5 月~2004 年 7 月收治并手术治疗的胃癌 110 例的临床资料进行回顾性分析。结果　110 例胃癌中,手术切除 101 例(91 .82%),其中根治性切除91例,姑息性切除10 例;远侧胃切除 78 例(77 .23%),近侧胃切除 7 例(6 .93%),全胃切除16例(15 .84%);行消化道重建的 104 例中,手法吻合 13 例(12 5%),单吻合器67例(66. 42%),双吻合器 24 例(23. 08%)。术后病理早期癌 9 例(8. 18%),进展期胃癌共 101 例(91 .82%)。术前肠外营养支持5~7天14例(12. 73%),术后行肠道营养86 例(85 15%),肠外营养90例(89 .11%)。手术死亡1例(0 .9%),12例发生术后近期并发症(9. 09%)。结论　胃癌患者早期诊断仍困难,但手术切除率及根治性切除率较以前明显升高,吻合器使用明显增加,有助于降低近期并发症发生率并提高肿瘤治疗的效果。需长时间营养支持时肠内营养较肠外营养更容易维持内环境稳定。     

Similar motion of a hand-held object may trigger nonsimilar grip force adjustments.

The tight coupling between load (L) and grip (G) forces during voluntary manipulation of a hand-held object is well established. The current study is to examine grip-load force coupling when motion of the hand with an object was either self-generated (voluntary) or externally generated. Subjects performed similar cyclic movements of different loads at various frequencies with three types of manipulations: 1) voluntary oscillation, 2) oscillating the right arm via the pulley system by the left leg (self-driven oscillation), and 3) oscillating the arm via the pulley system by another person (other-driven oscillation). During the self-generated movements: 1) the grip forces were larger and 2) grip-load force modulation was more pronounced than in the externally generated movements. The G-L adjustments are not completely determined by the mechanics of object motion; nonmechanical factors related to movement performance, for instance perceptual factors, may affect the G-L coupling.     

红花注射液治疗老年慢性肾功能衰竭32例临床观察

老年人肾功能随着年龄增长有“自然减退”现象，加上既往存在的高血压、糖尿病、慢性肾炎等疾病，更易出现慢性肾功能衰竭（CRF）。目前老年慢性肾衰的治疗目标是延缓肾功能减退的进程，主要的手段有控制血压、低蛋白饮食、纠正贫血、增加肠道排毒等。笔者采用中医活血化瘀的方法，通过静脉滴注红花注射液改善肾脏的供血，增加肾小球的滤过率，临床取得一定效果，现报道如下，供同道参考。[第一段]
