中风后癫痫的临床研究

本文报告３６例中风后癫痫发作的临床和ＣＴ资料。通过回顾性病历复习和随访发现，中风后癫痫的发生率占同期住院中风患者的５．２６％，以蛛网膜下腔出血和脑栓塞发生癫痫比率最高，分别为１５％和１２．５％。癫痫发作与ＣＴ所见病灶分布密切相关，皮质病灶较皮质下病灶更易发生病病。癫痫发作可发生于中风后任何时期，但早期癫痫以出血性中风多见，而迟发性癫痫则更多见于脑梗塞患者。     

Eigenstructure assignment with control gains optimization

Eigenstructure assignment using output feedback is reformulated using an auxiliary principle of minimization of control effort. In the general eigenstructure assignment procedure, the feedback gain matrix is uniquely determined for a set of explicitly specified desired eigenvalues and eigenvectors. However, for the controller design proposed in this paper, only the most necessary constraints are imposed on the desired eigenvalues and eigenvectors, and the unspecified model parameters of the closed-loop system are determined by minimizing the control effort. Numerical examples are presented for comparison of the proposed method with standard eigenstructure assignment methods, and an experimental example gives an insight into the feasibility of the proposed control algorithm with application to the vibration control of flexible structures undergoing forced vibration.     

农药唑呀威毒理及中毒治疗的实验研究

唑呀威（Ｔｒｉａｚｕｒｏｎ）系新型的高效杀蚜虫剂。目前，对其抑制胆碱酯酶活性的毒理尚报道不一。作者在进行毒性测试和发现１６名包装工夏季作业时８名出现明显症状的基础上，开展动物实验研究。结果发现，唑呀威有较有机磷农药更为快速的胆碱酯酶抑制作用，大鼠经口染毒１１２．５ｍｇ／ｋｇ仅３０ｍｉｎ内即见全血胆碱酯酶活性显著下降，Ｐ＜０．０１；且存在明显剂量－反应关系。高剂量（２００ｍｇ／ｋｇ）还可引起心血管系统的损害。注射阿托品有显著解救效果，染毒同时给药的解救效果明显优于染毒后５分钟给药，提示愈早给药解救效果愈好。作者由此提出了临床中毒急救措施的建议     

温阳健心灵口服液治疗充血性心力衰竭的临床与实验研究

以煎剂形成筛选治疗CHF的处方，发现温阳益气方改善泵血功能的效果优于单纯益气和养阴益气的处方。根据前方制备的温阳健心灵口服液保持了原煎剂的疗效，并被毒理学试验证明毒性极低。动物药效学及临床试验发现该药不仅能改善心衰犬和病人的左室收缩功能，还能改善其舒张功能。除此，它还具有利尿作用和使PAWA、SVR和PVR下降的作用，这也是它抗心衰的机理之一。90例的临床观察（疗程2周）表明该药总有效率、近期治愈率和显效率分别达88．9％、7．4％和18．5％，其效与开搏通组无明显差异。     

Chemotherapy in intracerebrally transplanted tumors induced with transplacental administration of ethylnitrosourea in rats

Summary Four tumors of the spinal cord were induced with ethylnitrosourea in rats by transplacental administration and transplanted into the brains of animals of the same strain. One of these intracerebrally grafted tumor lines (G-XIII) was followed up over the first 10 passages and treated with CCNU and other alkylating drugs. The results were compared with findings in an earlier established line (G-XII) in passage 12 and 59, which in the first instance was sensitive to CCNU. The CCNU application prolonged survival in treated animals in various treatment schedules in the first 10 intracerebrally grafted generations of the tumor up to 59%. Induction times of tumors became increasingly shorter. The susceptibility of early passages was similar in both lines. Its loss in late passages went together with diffuse growth of the tumor and reticulin fiber production. In addition, glial fibrillary acid protein expression and formation of intermediate filaments in perivascular tumor cells was lost.     

学时数较少的药学物理化学教学探索

根据课程学时的限制，结合药学专业课程的要求，对物理化学理论教学内容进行了取舍，强调上好第一课，并对部分内容进行双语授课的尝试，对实验教学也进行了探索。     

带真皮下血管网超薄皮瓣血运重建的实验研究（三）超薄皮瓣的再血管化与血供变化

以猪作为动物模型，对带真皮下血管网超薄皮瓣的血运重建规律进行了探讨。以超薄皮瓣为实验组，保留真皮下血管网皮片为对照组，按自身配对原则随机分为６个组。通过荧光素显色，透明标本，组织学，明胶墨汁灌注过程中超薄皮瓣的染色情况等观察，发现超薄皮瓣的再血管化发生在术后第５天，至第７天新生血管通过塑形趋于成熟。它既发生在皮瓣与受床之间，又发生在皮瓣与创缘之间，而且由皮瓣成活部分远端渐至近端。     

Benign coital headache

We studied the natural history of patients with a diagnosis of benign coital headache who presented to a private neurological clinic between the years 1978 and 1991. Thirty-two patients (24M, 8F) were invited to participate and 26 patients (83%) responded. The period of follow-up ranged from six months to 14 years (median 6 years). Thirteen patients (50%) had recurrent attacks of coital headache epochs separated by intervals of up to 10 years. Eleven of these patients suffered a concomitant primary headache whereas this was present in only one of those patients without recurrent attacks of coital headache (p < 0.001). In all but one patient, who had a transient blurred vision, the headache was not accompanied by nausea, vomiting, visual disturbances, sensory/motor disturbances, or unconsciousness. We concluded that benign coital headache can be clearly distinguished from headaches due to cerebral aneurysm or arteriovenous malformation rupture. The presence of a concomitant primary headache syndrome is a risk-factor for recurrence of coital headache.     

视网膜电图对玻璃体出血机化和玻璃体手术的意义

报告118例(133眼)由各种疾病引起的玻璃体出血机化患者的视网膜电图(ERG)检查结果,其中31例作了玻璃体手术,结果表明,ERG检查对玻璃体出血机化的患者,能客观地反映其网膜功能,并对玻璃体手术的预后有指导作用。术前ERG检查,a、b波下降越严重,视功能损害显著,术后视力的预后越差,同时证实,玻璃体机化膜是影响a、b波波幅和时间的一个因素。     

活动性结核标志物'H-多肽的实验与临床研究

本题研究是经免疫学途径直接检测人体感染结核菌的情况，为现代结核病的实验诊断、临床监测、流行病调查提供了一个全新的检验指标。作者首先发现了一种仅存在于活动性结核病患者体液中的蛋白成份—活动性结核标志物（ＡｃｔｉｖｅＴｕｂｅｒｃｕｌｏｓｉｓＭａｒｋ—ＡＴＭ）１Ｈ—多肽；并为之创立了独特的检测方法，经四年多临床１９４６０例样本调查中确定了ＡＴＭ的临床价值。将ＡＴＭ检测与ＯＴ皮试、酶联免疫ＥＬＩＳＡ、ＤＮＡ探针、ＰＣＲ基因扩增技术及典型病例组患者行Ｘ线计算机断层摄影（ＣＴ）、磁共振像（ＭＲＩ）等多组对比试验中，实验与临床研究资料分析证明：ＡＴＭ检测的总敏感度为８６．０６％、特异度９６．２４％、准确度９３．４５％、诊断效率为８２．８２％、批内ＣＶ１．２％、批间ＣＶ２．０％、Ｐ＜０．０５。经ＮＭＲ光谱分析结构含有ＣＣＨ２官能团。
