An Experimental Study on Homoharringtonine Liposome and Glaucoma Filtration Surgery

Purpose: To observe the inhibitory action of homoharringtonine liposome during the healing process of wounds in the filtering sitesMethods: posterior sclerectomies were performed in 14 rabbits. Postoperatively one eye of each rabbit received subconjunctival injections of HH liposome and fellow eye received saline injection in a randomized masked fashion.Results; Fourteen days after operation the IOP of experimental eyes reduced significantly (P < 0.01) as compared with the controlled eyes, and the number of remaining filtering blebs increased noticeably (P< 0.05). Pathohistological examination revealed that the number of fibroblasts per square micron in the filtering sites and the thickness of the scars in the center of the filtering sites of the experimental eyes were less than those of the controlled eyes. No serious ocular toxic and side effects were found.Conclusion : This experiment suggests that homoharringtonine liposome can markedly inhibit the scar formation of filtering sites after glaucoma fi     

蝙蝠葛碱抑制凝血酶诱导的血小板膜糖蛋白Ⅳ再分布和胞内α—颗？…

探讨蝙蝠葛碱对血小板聚集功能的影响。观察Ｄａｕ对血小板膜糖蛋白Ⅳ再分布和胞内α－颗粒凝血酶敏感蛋白释放的抑制作用。方法：应用流式细胞仪分别检测静息血小板ＧＰⅣ分布,ＴＳＰ释放。结果;Ｄａｕ并不影响静息血小板膜ＧＰⅣ和ＴＳＰ分布。而对活化血小板膜ＧＰⅣ再分布和细胞内α－颗粒ＴＳＰ释放具有明显的抑制作用,且两者的抑制作用呈显著正相关,这种抑制作用并不受Ｃａ＾２＋浓度的影响。     

针刺对急性高血压脑出血大鼠血浆ET和CGRP调整作用

目的：探索针刺对急性高血压大鼠治疗作用机制。方法：复制急性高血压脑出血大鼠模型。观察针刺对血浆ET和CGRP的影响。结果：针刺能降低血浆ET和升高CGRP。结论：针刺对急性高血压脑出血大鼠治疗作用与其降低血浆ET和CGRP密切相关。     

针刺四关穴治疗偏头痛及其对一氧化氮水平的影响

目的：观察针刺四关穴治疗偏头痛的疗效及其对血浆一氧化氯(N0)水平的影响。方法：对38例偏头痛患者以针刺四关穴治疗，并于治疗前后作血浆N0水平测定。结果：经治疗，患者总有效率78．95％；治疗后血浆N0水平明显升高。结论：四关穴针刺治疗偏头痛有确切疗效，其机理可能与升高血浆N0水平有关。     

Pneumatization of perpendicular plate of the ethmoid bone and mucocele]

OBJECTIVE: To find out the prevalence of pneumatization of perpendicular plate of the ethmoid bone, and to discuss the diagnosis and management of perpendicular plate mucocele (nasal septal mucocele). METHODS: The CT data from 32 patients with septal deviation were reviewed, and an unusual case of perpendicular plate mucocele was reported. RESULTS: Six cases (6/32, 18%) were found to have pneumatization of perpendicular plate of the ethmoid bone, with 2 located in the anterior portion (frontal-septal pneumatization), and 4 located in the posterior portion (spheno-septal pneumatization). A patient with perpendicular plate mucocele was treated by the technique of marsupialization under nasal endoscope. This patient was followed-up for 10 months without recurrence. CONCLUSION: As a kind of variation of nasal septum, the clinical significance of pneumatization of perpendicular plate should be emphasized. We reported the first case of perpendicular plate mucocele, originated possibly from the pneumatization of perpendicular plate of the ethmoid bone. Marsupialization under endoscope was considered to be the initial management for this unusual disease.     

论中医诊治非典型肺炎

本文回顾了50年来我国中医防治流行性乙型脑炎、麻疹、流行性出血热等流行性病毒疾病获得成功的经验，认为中医理论不把着力点放在对病原体的认识上，而是注重病原体侵入人体、病证斗争所表现的证候的辨证论治。作者提出诊治非典型肺炎的理论依据与特色。根据广东省中医院收治非典患者112例的临床观察，认为该病属中医春温温热疾病的范畴，并提出定名为春温病伏温证。本文详细记载该院中医治疗方案和典型医案。

药物流产后阴道出血与子宫刮出物病理学观察分析

目的　探讨药物流产后阴道出血时间与药流后妊娠残留物、血 β HCG的关系。 方法　应用米非司酮配伍米索前列醇时对 4 0 0例早中孕妇女进行药物流产和随访 ,对排出胚胎和绒毛组织后 30d内阴道出血量多、出血时间长、伴血 β HCG下降缓慢的 75例进行清宫术 ,刮出子宫内容物进行病理检查。 结果　变性炎症绒毛 13例 ,滋养细胞残留 30例 ,蜕膜组织 18例 ,全部伴有炎症细胞浸润 ;子宫内膜炎 12例 ,增生期或分泌期子宫内膜 2例。结论　药物流产后阴道出血时间长主要是绒毛、滋养细胞残留 ,一般伴血 β HCG下降缓慢或异常。     

1999至2001年广州地区临床常见肠杆菌科细菌耐药性监测结果分析

目的 了解临床分离常见肠杆菌科细菌的耐药性。方法 统一采用纸片扩散法进行实验，以美国NCCLS文件为判断标准，每次监测均有质控数据。结果 共有11家广州市三级甲等医院实验室参加耐药性监测，三年共统计临床常见肠杆菌科细菌3147株。结论 对肠杆菌科细菌，亚胺培南的耐药率最低，可考虑为临床首选药物，阿米卡星、头孢他啶耐药率相对较低，可选择用药。庆大霉素的耐药率有逐年下降的趋势，将来可能成为临床一线药。而磺胺甲噁唑／甲氧苄啶、四环素、萘啶酸等耐药率相对较高，应慎用。氨节西林的耐药率很高，应避免使用。
