简介：目的探讨重组内皮抑素(Endostatin)对兔角膜新生血管(cornealneovascularization,CNV)形成的影响.方法新西兰白兔18只,随机分为三组,每组6只12眼,采用角膜缝线法制备兔CNV模型,其中两组分别以浓度为10μg/ml、50μg/ml重组内皮抑素点眼,4次/d,连续19d,并以生理盐水点眼作对照.CNV生长面积采用计算机图像分析系统进行分析比较.结果10μg/ml、50μg/ml重组内皮抑素实验组自第7d开始CNV平均生长面积明显低于对照组(P＜0.05),两实验组CNV面积比较,差异无显著意义(P＞0.05).角膜组织病理学检查,实验组新生血管明显稀少,实验组与对照组炎性细胞成分及浸润程度相似.结论浓度10μg/ml、50μg/mlml重组内皮抑素具有明显抑制角膜新生血管生长的作用,而无毒副作用,为临床防治CNV提供了一种新的途径.

简介：目的探讨脑干听觉诱发电位(brainstemaudioevokedpotential,BAEP)在婴儿耳聋早期诊断的应用价值.方法500例婴儿从出生到6wk内耳声发射(otoacousticemissions,OAE)3次未通过者,拟诊耳聋的患儿进行听阈及BAEP检查.如听阈在65dBSPL以上或BAEP异常者,1～2个月后来复查.如患儿月龄在6-12个月以上,听阈仍在65dBSPL以上者就进行干预及治疗.结果1000耳中正常98耳、轻度耳聋515耳、中度耳聋234耳、重度耳聋80耳、极聋72耳.1～2个月后来复查的有754耳,正常的占233耳、轻度耳聋271耳、中度耳聋203耳、重度耳聋23耳、极度耳聋24耳.与首次比较差异有显著性(P＜0.01).结论BAEP检查可以检测婴幼儿听力损害的程度,及跟踪随访,并早期干预,早期治疗及早期语言训练成为可能,使患儿聋而不哑.

简介：目的：研究家兔静脉注射头孢哌酮钠／舒巴坦钠在眼内的透过性及蓄积作用。方法：用高效液相色谱法（highperformanceliquidchromatography，HPLC）测定给药后不同疗程时间点各组兔眼房水和玻璃体中的药物浓度。结果：房水中舒巴坦钠的药物浓度分别为23．4±4．8和23．6±3．7mg／L；头孢哌酮钠浓度分别为8．9±1．2和8．9±1．7mg／L；玻璃体中舒巴坦钠浓度分别为71．2±4．6和69．3±6．8mg／L，头孢哌酮钠未检出。结论：头孢哌酮Ca／舒巴坦钠静脉注射后在正常的眼内透过性不良。

简介：目的：分析小儿先天性鼻泪管闭塞所致泪囊炎的病原菌及其药敏结果,指导临床合理用药。方法：对先天性鼻泪管阻塞患儿98例110眼的泪囊分泌物进行病原菌分离培养及药物敏感试验。结果：从94眼的分泌物中共分离出155株细菌,病原菌阳性率为85.5%。其中革兰氏阳性球菌65.8%,革兰氏阴性杆菌23.9%。分离出的所有菌株对左氧氟沙星的敏感率为94.2%。结论：药敏试验表明绝大多数细菌对左氧氟沙星有较高的敏感性,对于小儿先天性鼻泪管闭塞所致泪囊炎可给予新喹诺酮类抗生素滴眼液治疗。
