Pattern-reversal electroretinograms and visual evoked potentials in branch retinal vein occlusion

We recorded pattern electroretinograms and visual evoked potentials in a group of selected patients with unilateral uncomplicated branch retinal vein occlusion. To document the effects of preexisting risk factors, patients were divided into three groups: diabetes mellitus, hypertension with hyperlipidemia and no systemic disease. The transient and steady-state pattern electroretinogram and visual evoked potential amplitudes were significantly reduced and visual evoked potential peak times were delayed relative to the fellow eyes and agematched normal subjects. There was a second amplitude reduction relative to the other patient groups in both the affected and fellow eyes of the diabetes mellitus group, which was indicative of an additive effect of diabetes mellitus.Abbreviations BRVO branch retinal vein occlusion     

51例黄磷烧伤临床分析

对５１例黄磷烧伤病人进行临床分析。结果表明：黄磷对人体毒性大，即使烧伤面积不大，亦可因磷中毒而丧。磷中毒易造成肾、肝等裨性器官的损害。硫酸铜用于烧伤创面用量过大易引起铜中毒致急性溶血性贫血，不可作为黄磷 伤的创面用工。     

氯胺酮对脑缺血大鼠突触体ATP酶活力的影响

目的 研究氯妥酮（ＫＴ）对大鼠脑缺血ＡＴＰ酶活性变化的影响。方法 采用大鼠四动脉阻断脑缺血模型，缺血１０ｍｉｎ后测量纹状体和海马突触体Ｎａ＾＋、Ｋ＾＋－ＡＴＰ和Ｃａ＾２＋－＝ＡＴＰ酶活性。结果 脑缺血时两个脑区的ＡＴＰ酶活性均显著下降。缺血的前预先应用ＫＴ２５ｍｇ．ｋｇ＾－１和５０ｍｇ．ｋｇ可拮抗脑缺血时ＡＴＰ酶活性的下降。结论 ＫＴ可通过拮抗脑缺血时ＡＴＰ酶活性的下降对抗脑缺血损伤。     

慢性肝病患者血清和腹水肿瘤坏死因子—α检测的临床意义

目的：了解慢性肝病患者血清和腹水肿瘤坏死因子－α检测的临床意义。方法：采用双抗体夹心ＥＩＳＡ法，对２０例慢迁肝、２０例慢活肝和２９便肝硬化代偿期病人血清ＴＮＦ－α进行检测；对２１例肝硬化腹水无自发性腹膜炎（ＳＢＰ）者、２３例肝硬化腹水并ＳＢＰ者、２５例肝癌腹水者和２４例胃肠癌腹水者进行血清和腹水的ＴＮＦ－α检测。结果：血中ＴＮＦ－α水平在下列各组疾病呈逐渐上升（慢迁肝组〈慢活肝组和肝硬化代偿期组〉     

狼疮抗凝物质45例临床分析

本文报道从1985年7月到1993年12月检出有狼疮抗凝物质患者45例,有血栓栓塞现象14例,占31.11％。我们就其病种、临床表现、实验室检查、治疗及预后进行分析。     

对－苯二甲酸衍生物的合成及其诱导分化HL－60细胞的活性

作者合成了１３个对－苯二甲酸衍生物，其中有９个化合物尚未见文献报道。通过对ＨＬ－６０细胞诱导分化活性试验，发现有两个化合物在浓度为５×１０￣（－６）ｍｏｌ／Ｌ时，可使细胞分化率达５５％，低于维Ａ酸的分化率（７９％，１０￣（－７）ｍｏｌ／Ｌ）。     

特区农村城市化进程中损伤中毒及其外部原因分析

对某医院10年损伤和中毒及其外部原因进行统计分析,结果表明:开放性创伤和血管损伤、骨折、颅内和体内损伤(包括神经)是前3位的损伤中毒;机动车交通事故、机器切割和穿刺工具引起的事故、他杀和他伤是损伤和中毒的主要外部原因。颅内和体内损伤(包括神经)是损伤中毒的最主要死因。1999年后该院的损伤中毒病人有明显上升。烧伤、经腔口进入异物这两类损伤的顺位在上升。     

隐动脉筋膜蒂的交腿皮瓣修复小腿严重软组织缺损

目的探讨一种小腿严重软组织缺损的修复方法。方法以健侧隐动脉为蒂的顺行或逆行交腿皮瓣修复患侧小腿软组织缺损。结果本组8例均有效地覆盖受区创面,随访三个月,皮瓣全部成活。结论该皮瓣不牺牲小腿的重要血管,质地与受区相似,方法简单易行,血运可靠,血管蒂长,是修复小腿严重软组织缺损的较好方法。     

果胶酶治疗胃石症的临床研究

目的 探讨胃石症的发病机制。分析和总结果胶酶治疗胃石症的疗效。方法 在体外将山楂，柿子嚼碎后置入新鲜胃液，分为加白酒和不加白酒两组后放入37℃恒温箱内，观察胃石形成的经过及时间，再分别加入果胶酶，观察其解聚过程及时间，对54例胃石症患服用果胶酶治疗并观察疗效。结果 加白酒组形成胃石的速度较快，果胶酶能有效溶解胃石。54例患服用果胶酶6h后吞钡透视见胃石完全消失，症状，体征完全缓解。结论 果胶酶能有效溶解胃石。是治疗胃石症的有效方法。     

舰船员慢性荨麻疹与马拉色菌相关性研究

OBJECTIVE: To investigate the association of Malassezia furfur with chronic urticaria in the crew members of ships. METHODS: A comparative mycological study of 126 crew members of ships with chronic urticaria and 45 normal control subjects was carried out. The 82 urticaria patients identified as positive for Malassezia furfur were divided into groups A and B to receive treatment with antihistaminics (group A) and antihistaminics combined with 2% ketoconazole shampoo(group A). RESULTS: The carrier rates of Malassezia furfur were significantly higher in urticaria patients than in the normal control subjects (P<0.01), but in view of the case ratios of the final cure or improvement, no significant difference was observed between the two groups by the end of the treatment courses (P>0.05). But 6 to 8 weeks from the end of the treatment course, better therapeutic effect was noted in group B (P<0.01), with higher rate of negative Malassezia furfur findings (P<0.01). CONCLUSION: Malassezia furfur may play an important role in the prevalence of chronic urticaria among the crew members, and anti-fungal treatment may produce better long-term therapeutic effect.
