冠心病行为模式与心理状态的相关性探讨

目的为探讨Ａ型行为在冠心病（ＣｏｒｏｎａｒｙＨｅａｒｔＤｉｓｅａｓｅ，ＣＨＤ）中的作用及与心理状态的相关性。方法对１１４例ＣＨＤ及３７例非ＣＨＤ应用心理测验方法对照调查。结果发现Ａ型行为的人易患ＣＨＤ。ＣＨＤＡ型行为者在焦虑、抑郁、人际关系、认识、敌对性症状因子分较ＣＨＤ非Ａ型行为者有明显增高。ＣＨＤ非Ａ型行为者也具有一些特有的心理症状。结论ＣＨＤ病人的行为模式与病后的某些心理表现呈正相关。     

白血病患者血浆和外周血白细胞内维生素变化

检测４５例正常人和４４例不同病期白血病血浆和外周血白细胞内维生素Ａ、Ｅ、Ｃ、Ｂ１２和β－胡罗卜素、叶酸浓度。结果表明，初治白血病患者血浆维生素Ａ、β－胡罗卜素降低（Ｐ＜０．０１），未缓期解者血浆β－胡罗卜素和叶酸低于正常（Ｐ＜０．０１和Ｐ＜０．０５）。在初治和未缓解期患者的外周血白细胞内，维生素Ｅ、Ｃ、Ｂ１２和β－胡罗卜素均显著降低（Ｐ＜０．０１～０．００１）。而且，外周血白细胞内维生素代谢异常比血浆更为显著。提示维生素含量变化对于解释病因，预测疗效及估计预后有一定的价值。     

滥用药物与生命质量退化的伦理思考

本文从生命质量的内涵入手,分析了滥用药物的直接和间接、近期和远期的危害,通过论证得出了滥用药物必将引起人类生命质量退化的结论.以期从一个新的认识度唤起人们对滥用药物问题的重视、并由此引出了一些对医学目的以及滥用药物控制措施的思考.     

常见肿瘤患者血清维生素A,E,C水平

本文报告２６０例恶性肿瘤患者血清维生素Ａ、Ｅ、Ｃ水平的测定结果。发现除慢性白血病外，蓁７种恶性肿瘤患者血清维生素Ａ水平平均显著低于健康人（Ｐ＜０．０１）；急性白血，肝癌、食管癌患者血清维生素Ｅ水平显著低于健康人（Ｐ＜０．０５）；急性粒细胞白血病、急性单核细胞白血病、肝癌患者血维生素Ｃ水平显著低于健康人（Ｐ＜０．０１）。本研究工作为维生素Ａ、Ｅ、Ｃ药物在肿瘤临床上的应用提供了参考。     

烧伤后检测血儿茶酚胺类、血糖及血胰岛素的临床意义

我们对３０例住院病人用荧光分光光度法测定了不同烧伤时间、不同烧伤指数（ＢＩ）血儿茶酚胺类（ＣＡ）释放量，以期了解病人的应激状况，同时测血糖（ＢＳ）和用放射免疫法测血胰岛素（ＳＩ）。结果表明烧伤后ＣＡ类释放是持续性的，且有休克和感染两个高峰（Ｐ＜０．０５，Ｐ＜０．０１）；ＣＡ类释放主要是去甲肾上腺素（ＮＥ）的持续性增加，是正常量的两倍以上。休克期ＣＡ类释放如不增加，脓毒症阶段肾上腺素（Ｅ）与去甲肾上腺素从高值骤然下降，且低于休克期。提示：交感－肾上腺系统已处于衰竭状态，死亡似不可避免，而胰岛素分泌正常或相对不足。因此我们认为，ＣＡ类释放增加、糖原异生、胰岛β细胞分泌受抑制，是烧伤后全过程内分泌变化的主要原因。扩容纠酸、早期切痂预防感染以及使用抗ＣＡ类药物是防治的主要措施。     

Microvascular corrosion casting of normal tissue, transitional mucosa and adenocarcinoma in the human colon.

The microcirculatory architecture of normal tissue, transitional mucosa and adenocarcinoma of the human colon was investigated with microvascular corrosion casting (MVCC) combined with scanning electron microscopy (SEM). The study showed that the capillaries within the normal mucosa were arranged in a regular hexagonal pattern around the mucosal glands and that the microvessels of transitional mucosa mostly had lost the typical hexagonal pattern and become slightly wider in diameter. The microvessels in the tumor periphery were increased in number and disorganized, and presented large variation in morphology with claw-like formations, widened sinuses, diverticula and appendixoid patterns. Microvessels were lacking in the central areas of tumors. These morphological alterations may serve as additional indicators of tumor development.     

华蟾蜍毒素对离体豚鼠输精管的作用

华蟾蜍毒素(华蟾素)使离体豚鼠输精管产生剂量依赖性收缩反应,利血平化豚鼠输精管及冷藏输精管对华蟾素反应减弱。给酚妥拉明、维拉帕米后,输精管对华蟾素反应均受抑制,溴苄胺可使反应潜伏期缩短。结果提示华蟾素收缩输精管反应可能与其促进肾上腺素能神经末稍NA释放有关。     

The value of hysteroscopy in the diagnosis of infertility and habitual abortion.

Ninety cases of infertility and habitual abortion were analyzed by hysteroscopy between April 1983 and July 1990 in PUMC hospital. Abnormal changes of the uterine cavity were seen in 74.4%. The result of hysterosalpingography corresponded with that of hysteroscopy in 62.5%, and the result of B-ultrasound corresponded to that of hysteroscopy in 52.5%. The diagnosis of adhesion and polyps of the uterine cavity was made accurately by hysteroscopy, and both could be operated under hysteroscopy. After operative removal of the adhesion, an IUD should be put into the uterine cavity for 3 months. In 60 cases operations were performed during or after hysteroscopy. Of the 45 patients followed, 19 achieved pregnancy. Five patients achieved pregnancy after operative removal of the adhesion. It is concluded that hysteroscopy is more important than B-ultrasound and hysterosalpingography in the examination and treatment of infertility.     

The use of 6-flavor Rehmannia decoction with additives in the prevention of ototoxic deafness induced by gentamicin in guinea pigs]

The purpose of this study is to discuss the effects of the Chinese medicine six-flavor Rehmannia Decoction with additives on preventing deafness induced by gentamicin (GM) in guinea pig by means of testing the thresholds of Preyer's reflex (PR) cochlear microphonic potential (CM), action potential of the auditory nerve (N1) and scanning electron microscope of inner ear (SEM). The results showed that the medicine is effective in reducing the ototoxic effect of GM on inner ear.
