右侧升结肠癌合并感染个案病例误诊报告

目的：总结右侧结肠癌误诊和漏诊的原因，寻求对策。方法：回顾性检查造影的全过程。结果和讨论：右侧升结肠充钡较少，激惹现象明显，远端有结肠癌的部分特征但未引起重视。误诊和漏诊的原因：结肠充钡较少，X线表现不典型，对病症认识不足，片面相信结肠镜的结果。     

急性脑血管病患者SDS-AGE尿蛋白电泳测定的临床意义

目的　探讨急性脑血管病 (ACVD)患者早期肾损伤的诊断方法。方法　收集 6 1例ACVD患者治疗过程中的晨尿 ,按传统肾损害标准分为无肾损害组和有肾损害组 ,用十二烷基磺酸钠 琼脂糖凝胶 (SDS AGE)进行非浓缩尿蛋白电泳 ,分析 2组患者的尿蛋白组分。对SDS AGE诊断为肾损害的患者再进行病理活检确证。结果　ACVD患者传统的无肾损害组已有 15 .3%存在早期的肾损害。SDS AGE判断肾脏损害与肾活检结果相符。ACVD患者早期的肾损害主要是肾小管损害。结论　SDS AGE电泳操作简便快速 ,敏感性强 ,诊断符合率高 ,可作为ACVD患者治疗过程中判断早期肾损害的敏感方法。

Effects of 5-Hydroxytraptamine on Aggregation,Release Reaction and Mobilization of Cytosolic Free Calcium Concentration in Rabbit Normal and Washed Single Platelets

In rabbit platelet rich plasma (PRP), 5-hydroxytraptamine (5-HT,0.03～3μmol/L) induced decrease in light transmission (DLT) dose-de pendently with centralization, as revealed by electron microscopy. However, 5-HT did not induced platelet aggregation and release reaction. 5-HT-induced DLT was inhibited by methysergide (0.3～30μmol/L), indomethacin (0.3～10μmol/L) and PGE_1 (0.01～0.3μmol/L) in a dose-dependent manner, but not EGTA(0.3～3mmol/L). Collagen(Coll), arachidonic acid (AA), adenosine diphosphate (ADP) and a stable thromboxane A2 analoge(STA_2) also induced DLT before aggregation by themselves, which was also inhibited by PGE_1, but not inhibited by EGTA except for Coll However,Coll-, AA-, STA_2-and ADP-induced DLT were reduced by pretreatment of PRP with 5-HT dose-depen-dently. The duration of DLT by Coll and AA were decreased from 151.4±5.93 sec and 15(?)38±0.60sec to 45.44±4.04 sec and 9.00±1.25 sec respectively ((?)±s(?) P<0.01), but not by ADP and STA_2, 3μmol/L of ADP-and 0.3μmol/L of STA_2-induced aggregation which was not accompanied with release reaction were enhanced by 5-HT pretreatment, but in those (Coil 5μg/ml, AA 100～200μmol/L and STA_2 1～3 μmol/L) with release reaction, the amount of adenosine triphosphate(ATP)were suppressed significantly (P<0.001) by 5-HT pretreatment without the effect on the magnitude of aggregation, The mobilization of cytosolic free calcium concentration ([Ca~(2+)]i) was observed after 5-HT treatment in single washed platelet, the results indicated that the basic level of [Ca~(2+)] i was 64.78±3.24nmol/L and this level was increased dose-dependently and significantly at 30 sec after administration of 5-HT and the time of peak value of [Ca~(2+)] i was at 90～100 sec.The similar time courses of suppression of ATP released during aggregation, in cases of Coll(5μg/ml), AA (200μmol/L) and STA_2(3μmol/L), by 5-HT were also found in the present experiment.     

干扰素治疗眼内新生血管病变

眼内新生血管病变是一类严重影响视力的疾病。日前，除全视网膜激光光凝外，尚缺乏简易有效的治疗方法．近来，α-干扰素应用于实验及临床治疗新生血管病变取得了良好的效果。由于α-干扰素可以抑制细胞胸腺嘧啶脱氧核苷的转运与磷酸化，进一步抑制细胞DNA的合成及其通过有丝分裂s期而抑制其增生．它可有效地抑制血管内皮细胞的生长与迁移，故可抑制新生血管的发生。目前，新生血管的发病机理及α-干扰素的药理学作用机理尚未能从分子生物学水平完全阐述清楚，但其效果肯定． （中华眼底病杂志，1994，10：121-123）
