溃疡病男性患者血浆睾丸酮和雌二醇浓度的变化

本文对20例溃疡病男性患者和20名男性健康者进行了血浆睾丸酮和雌二醇则定。两者相比,溃疡病男性患者血浆睾丸酮水平虽较健康者为高,但经统计学处理,无显著差异(t:1.616 P>0.05);而血浆雌二醇水平,溃疡病男性患者低于健康者,经统计学处理,有显著差异(t:2.53 P<0.05)。     

Effect of 5-Aminoisoquinolinone on the Adhesion of Colon Carcinoma

Objective： 5-Aminoisoquinolinone, a water-soluble, potent inhibitor of the activity of poly （adenosine 5＇-diphosphate ribose） polymerase, plays an important role in the tissue injury associated with ischaemia-reperfusion injury and inflammation by inhibiting the activity of poly （adenosine 5＇-diphosphate ribose） polymerase and the expression of cell adhesion molecules such as ICAM-1, P-selectin et al. But how about it in the tumor is not clear. The aim of the present study was to study the effects of 5-Aminoisoquinolinon on the adhesion of colon carcinoma line HT-29 cells to human umbilical vein endothelial cells; and the effects of 5-Aminoisoquinolinon on the expression of ICAM-1, P-selectin and the activity of poly （adenosine 5＇-diphosphate ribose） polymerase in colon carcinoma HT-29 cells. Methods： The adhesion of HT-29 cells to human umbilical vein endothelial cells was detected by adhesive experiment. Immunocytochemically Streptavidin-Peroxidase method was used to investigate the expression of ICAM-1, P-selectin and Poly （adenosine 5＇-diphosphate ribose）（ the product of poly （adenosine 5＇-diphosphate ribose） polymerase activation）. Results： the results of the adhesion assay of HT-29 cells to HUVEC showed that the OD570 value in each 5-AIQ-treated group was significant lower than that in the control group （5-AIQ-untreated） in a dose-dependent manner. The expression of ICAM-1, P-selectin and Poly （adenosine 5＇-diphosphate ribose） was significant lower in 5-Aminoisoquinolinone-treated HT-29 cell group than that in 5-Aminoisoquinolinoneuntreated groups. Conclusion： The data suggest that 5-Aminoisoquinolinone can inhibit the adhesion of HT-29 cells to human umbilical vein endothelial cells. 5-Aminoisoquinolinone also can inhibit poly （adenosine 5＇-diphosphate ribose） polymerase activation and the expressions of ICAM-1 and P-selectin in HT-29 cells. 5-Aminoisoquinolinone probably contributes to the prevention of tumor cell metastasis. Further study is needed.     

甘利欣辅助治疗皮肌炎、系统性红斑狼疮疗效观察

目的 对甘利欣辅助治疗皮肌炎、系统性红斑狼疮的临床疗效及安全性进行临床评价。方法 采用非盲法半随机对照法，试验组10例，对照组11例，均据病情需要使用激素，试验组辅以静滴甘利欣250～300mg/d，观察2～3周。结果 皮肌炎、系统性红斑狼疮对照组的总有效率为72.7%，试验组为80%；但两组间差异无统计学意义（P〉0.5）。皮损好转及生化酶学改变亦无统计学意义。不良反应轻微。结论 甘利欣辅助治疗皮肌炎、系统性红斑狼疮的临床疗效尚需进一步研究。     

人胎儿前庭器超微结构的观察

对人胎儿前庭器超微结构的研究,国内外报道甚少。本文对18至36周人胎儿颞骨10具进行了扫描电镜和透射电镜的观察,并对应用Surface preparation法制做人胎儿前庭器标本的方法进行了探讨。本文观察所见:豚鼠平衡斑的生理状态与人胎儿很近似,体面积比人胎儿平衡斑小,感觉毛长,细胞排列更整齐。28周以后的胎儿因前庭周围骨质变硬,制做标本时可以分别取出两囊斑和壶腹嵴。     

测胎儿器官重量探讨其生长发育规律

根据1022例新鲜胎尸的不同受精龄与体重，十项重要器官（心、肝、脾、左右肺、左右肾、左右肾上腺、胸腺等）的重量进行测量，将所测得的原始数据输入到IBM-PC/XT微型计算机内进行数据处理。探讨胎儿生长发育的基本规律。结果：（1）建立了胎儿体重与胎龄之间的推算式；（2）建立了胎儿各重要器官重量与胎龄之间的推算式；（3）建立了胎儿体重每月平均增长量与胎龄之间的推算式；（4）按胎儿体重每月平均增长量，用有序聚类分析方法，将胎儿生长发育过程划分为三个阶段。     

风心病房颤瓣膜术后的转复——21例临床分析

本文分析21例风湿性瓣膜病心房纤颤于手术后的转复治疗效果,指出在心瓣膜手术后转复房颤有成功率高、窦律维持时间长的效果。而术前左房大小、房颤持续时间长短和术后心功能改善程度等都直接影响转复成功与否及窦律维持期限。此外对单用电击转复和电击前采用预备药乙胺碘呋酮这两种方法进行了初步比较。     

THE CAIMA SYSTEM

CAIMA is the abbreviation of Computer-Assisted Instant Monitoring drug Administration. CAIMA works on the principle of closed-loop negative feedback. Special programs have been designed to meet the needs of: a) Patients' safety, b) Response level desired, c) Output necessary for actuating the injecting pump. The pump forces the drug solution to enter the body with high precision. The author shows 8-year experience of using CAIMA system in laboratory and in hospital operating rooms. Experimental studies revealed that: CAIMA system attenuates the overshots and undershots usually present in reaction to drug administration, thus saves the drug and thereby causes less side-efiffeets, while the recovery is also much shortened. CAIMA system provides a greater tolerance to extra-stimuli and preserves the body original reactive sensitivity to drug. The homeostasis in animals is better kept with CAIMA than without. Clinically, the arbitrary hypotension during brain surgery with sodium nitroprusside and the control of muscle relaxation in general surgery with muscle relaxants have been successful using CAIMA system.
