CGRP免疫反应神经纤维在大鼠胆总管与十二指肠连接处的分布

用免疫组织化学ＡＢＣ法，研究了降钙素基因相关肽（ＣＧＲＰ）免疫反应神经纤维在大鼠胆总管末端与十二指肠连接处的分布。大鼠的胆总管末端有较丰富的ＣＧＲＰ免疫反应神经纤维，它们多呈串珠（膨体）状，少数为无膨体的细长纤维。ＣＧＲＰ－ＩＲ纤维主要分布肌层及血管周围，在神经纤维的附近可见到含ＣＧＲＰ－ＩＲ阳性颗粒的肥大细胞。本实验为神经免疫调节机制的研究提供了形态学依据。

巩膜隧道小切口白内障摘除76例疗效观察

目的:探讨基层医院开展白内障摘除人工晶体植入术简便易行的术式。方法:比较76例巩膜隧道6 mm小切口与对照组12 mm大切口术后视力、角膜散光等。结果:由于6 mm巩膜隧道小切口下前房保持好,空间大,易操作,故术后视力≥0.5者占59.2%以上,角膜散光手术前后变化仅为0.08 DS。结论:基层医院在有限条件下开展白内障摘除人工晶体植入术,采取巩膜隧道内小切口术式值得一试。     

脑动脉瘤破裂伴发急性硬膜下血肿的诊治

目的 探讨脑动脉瘤(AN)破裂所致的急性硬膜下血肿(ASDH)的临床、影像学特点和诊治方案。方法 回顾288例破裂AN，发现10例伴有ASDH。Huni Hess分级，Ⅱ级3人，Ⅲ级1人，Ⅳ级3人，Ⅴ级3人，均经CTA诊断为AN破裂，除2例外均被脑血管造影或手术所证实。保守治疗2例，血肿清除加AN夹闭术4例，电解脱弹簧圈(GDC)栓塞后加血肿清除2例，栓塞加脑室外引流1例，单纯栓塞l例。结果 疗效优者2例，中残者l例，7例死亡。结论 AN性ASDH的预后极差，同术前分级相关；CTA检查后立即行血肿清除加动脉瘤夹闭有助于提高预后，合适患者可联合栓塞和血肿清除术。     

Antimicrobial susceptibility of respiratory Haemophilus influenzae strains isolated from pediatric respiratory tract infections

BACKGROUND: Haemophilus influenzae (H. influenzae) is the most frequent bacterial pathogen of respiratory tract infections in children. Detection of antimicrobial susceptibility of H. influenzae is necessary for institution of appropriate antibiotic treatments. METHODS: A total of 281 strains of H. influenzae isolated from sputum samples of 281 pediatric patients with respiratory tract infections were recruited for study. Antibiotic susceptibility was determined by assessing minimum inhibitory concentrations (MIC) of antimicrobial agents. MIC were measured by utility of Agar dilution susceptibility test. RESULTS: Of the total, 38 (13.5%) strains produced beta-lactamase (BLP), 56 (19.9%) strains were beta-lactamase non-producing, ampicillin resistant (BLNAR). The overall resistant proportion to ampicillin was 33.4%. The data indicated that sulbactam/ampicillin, cefotaxime, ceftriaxone and cefditoren are effective against BLP strains. In addition, a high prevalence of BLNAR H. influenzae strains was identified, with an overall isolation rate of 19.9%. Those strains mainly demonstrated intermediate level to ampicillin (ampicillin-MIC 相似文献   

A preliminary study of the relationship between antibiotic administration and changes in bacteriological profile of wound infection in a burn unit

Objective:To investigate the relationship between antibiotic administration and the changes in bacteriological profile in a burn unit. Methods: The data of consumption of different kinds of antibiotics, including total antibiotic consumption [expressed as the number of defined daily doses (DDD)] as well as pathogen identification, were collected in a 8-year period. The constituent ratios of different kinds of antibiotics in total antibiotic consumption to isolation rates of various species of bacteria were calculated, and their correlation was analyzed. Results: Within this period, it was found that the aminoglycosides and first generation cephalosporins were used less frequently, while the polypeptides, carbopenem and macrolides were used proportionally more. At the same time, the isolation rates of Staphylococcus aureus, Acinetobacter sp, Enterobacter cloacae, Klebsiella pneumoniae and methicillin-resistant Staphylococcus aureus were gradually increased. The constituent ratios of predominant pathogens were correlated to the different kinds of antibiotics consumption in the burn unit. Conclusion: The results suggested that the consumption of different antibiotics was closely related to the trends of emergence of bacterial isolates from infected burn wounds. The result might imply that to regulate the administration of certain antibiotics might help decrease the emergence of certain pathogenic bacteria in burn infections.     

睫状体缝合复位术的临床观察及护理

目的:探讨适合睫状体缝合复位术病人的护理方法。方法:对34例(34只眼)因外伤致睫状体分离和脱离导致低眼压,随后行睫状体缝合复位术的病人进行观察和护理。结果:32只眼术后1周至6个月眼压恢复正常,其中5只眼术后2～5个月内分别进行第二次手术或氩离子激光光凝而痊愈。视力改善者21例,无变化者13例。结论:睫状体缝合复位术是治疗外伤性睫状体分离和脱离的有效方法。术前行超声生物显微镜(UBM)检查、术后密切观察眼压变化并给予正确处理、做好心理护理和出院指导是确保手术成功的重要措施。
