急性期中风中医诊断与颅脑CT扫描关系分析

分析325例急性期中风的病类、证名诊断与颅脑CT扫描所见的关系,认为中络、中经以缺血性改变为主,病灶小,病灶周围多清晰或仅见模糊,占位表现不明显或较轻;中腑、中脏以出血性改变为主,病灶大,病灶周围多见水肿或模糊不清,占位表现明显,两者对比差异极显著(P<0.01)。病类诊断与中风的病变部位、病位侧、病灶数目;证名诊断与颅脑CT扫描所见皆关系不大(P>0.05)。     

溃疡病的病机及临床治疗探讨

本文通过对364例溃疡病患者的住院系统治疗观察,认为溃疡病的主要病机是脾虚。活动期与肝郁及胃热有关;迁延难愈多因胃络瘀阻;胃酸增高为本病的普遍现象。故本病治疗应以健脾胃,佐以疏肝活血、清热、制酸之法。方药如用四君子汤加黄芪、白芍、郁金、三棱、蒲公英、乌贼骨等为基础方加减;对有胆汁返流者,则应配以疏肝清胆,降逆通腑之品。临床近期治愈率可达82.4％。     

A群多糖脑膜炎菌苗最适免疫剂量的研究

近些年来对Ａ群多糖脑膜炎菌苗最适免疫剂量进行了一系列现场流行病学及血清学效果的对比研究。首先肯定了我国生产的菌苗与法国Ｍｅｒｉｅｕｘ研究所生产的苗苗在人体接种后观察一年内具有同等杀菌抗体反应。以后在严格对比下观察了国内生产的多糖菌苗接种３０μｇ及５０μｇ一年内的血清杀菌抗体反应。结果完全相同；而全身反应则３０μｇ为５０μｇ剂量的五分之一。在我国８０年代流脑流行地区内确证了３０μｇ免后人群保护率为９９％与国外５０μｇ的保护率（９７．２％）相似。国内连续三年在流行地区内对比观察了３０μｇ、与５０μｇ的流行病学预防效果，其人群保护率相似．与国外（Ｒｅｉｎｇｏｌｄ）．的报告亦相似。最后结论是本菌苗的最适免疫剂量为３０μｇ．不但其预防效果与５０μｇ相同，而且菌苗反应轻微，经济效益高，有利于在发展中国家推广使用。     

流行性出血热患者血清超氧化物歧化酶、丙二醛含量变化与其发病机理的关系

本文测定32例健康人和101例流行性出血热(EHF)患者血清超氧化物歧化酶(SOD),丙二醛(MDA)的含量。结果表明EHF患者血清SOD、MDA含量均高于健康对照组,以低血压少尿期升高最为明显。测定中还发现SOD、MDA含量升高与病情变化程度有一定关系。作者认为自由基参与了EHF的发病过程。研究EHF与自由基的关系有助于进一步阐明EHF的发病机理并为其临床治疗提供一定的参考价值。     

Evaluation of stroke rehabilitation by randomized controlled studies: a review

In all, 22 reports of 20 randomized, controlled rehabilitation studies were evaluated. In 18 of these, the design of the trial was parallel, with a cross-over format being employed in the remaining 2 instances. Seven studies related to intensive rehabilitation during the early post-acute period. In six others, specific techniques--sometimes associated with traditional physiotherapy procedures--were compared: biofeedback, perceptual retraining, and amphetamine treatment. Eight experiments evaluated speech therapy in aphasia. Frequently, methodological considerations limited the interpretation of the results. The review showed that: 1) as regards activities of daily life and motor function, differences as between rehabilitation in stroke units on the one hand and non-rehabilitation or rehabilitation in medical wards on the other, were detected in relatively few quality studies and remained particularly inconclusive insofar as life in the home environment was concerned; 2) rehabilitation for aphasia and perceptual dysfunction proved effective for at least several months after acute stroke; 3) in general, examination of the reports cited revealed no differences in the effects of biofeedback and perceptual retraining vs conventional physiotherapy; 4) rehabilitation, whether administered by specialists or amateur caregivers purpose-trained by specialists, proved equally effective for aphasia. These conclusions constitute a valuable basis for the development and evaluation of modern rehabilitation programs for stroke patients.     

心脏病患者血浆心钠素浓度初探

本文报道了采用放射免疫分析法检测的136例健康人和95例心脏病患者血浆心钠素含量的结果。健康人血浆心钠素含量为460．86±23．68ng／L，男女之间，年龄之间无明显差异。心脏病患者的血浆心钠素浓度均高于健康人，心脏病患者心功能越差，血浆心钠素浓度越高，其中以肺心病组变化最为明显。     

The implantable cardioverter defibrillator:the end of the thoracotomy approach

Internal cardioverter defibrillator (ICD) implantation has become a standard therapy for life-threatening arrhythmias. A simple and safe surgical implantation technique is therefore mandatory in this high risk population. In a 30-month period 86 patients received 87 ICD devices. An endocavitary lead system was used as first choice in 62 patients and defibrillation thresholds (DFT) of 25 joules (J) or less were obtained in 57 patients. A thoracotomy approach was avoided using a biphasic shock wave form in 17 patients and the addition of a subcutaneous (sc) patch in 11 patients or wire array lead in 9 patients. There was one early non-technique related death (1.7%) after the transvenous approach. Reoperation was necessary in three patients with lead complications and in two patients for local device problems (one migration, one infection). With the recent progress in ICD technology, a thoracotomy approach could be avoided for the last 52 patients. For comfort and cosmetic reasons left subcostal insertion of the device has been successfully used in the last 50 patients. We conclude that the nonthoracotomy approach can now be offered to all patients in need for an ICD as a consequence of the technological progress made in the field of electric treatment of malignant ventricular arrhythmias. A stepwise approach with a minimum of implanted hardware and the use of biphasic shock systems now offers a simple and efficient treatment alternative with very low perioperative risk. Internal cardioverter defibrillator implantation in combination with open heart procedures can easily be avoided.

The pro-LHRH system of the rat brain. effects of changes in the endocrine background

The gonadotropin-releasing hormone-associated peptide (GAP) and luteinizing hormone-releasing hormone (LHRH) portions of the LHRH precursor were localized by immunocytochemistry in prepubertal female rats, in adult female rats at different stages of the estrous cycle, and in ovariectomized rats. Our results indicate that GAP is present in the same population of neurons as LHRH in the rat brain. These results confirm the specificity of previous immunocytochemical studies which used antisera to LHRH alone. The endocrine status of the animal was demonstrated to affect the immunocytochemical appearance of the GAP system. The number of GAP immunopositive cells and terminals is highest during diestrus II and lowest on the day of estrus, suggesting either a role in and/or a dependence upon the endocrine changes associated with the estrous cycle. Ovariectomy results in a gradual decrease in GAP immunoreactivity in the median eminence. This observation, in concert with other recent studies, suggests that ovarian factors may be acting to maintain the LHRH system and that ovariectomy may result in decreased synthesis and/or processing of the LHRH system and that ovariectomy may result in decreased synthesis and/or processing of the LHRH precursor.     

丙型肝炎患者外周血单核细胞中丙型肝炎病毒复制的研究

９例临床诊断为丙型肝炎患者，研究其外周血单核细胞中ＨＣＶＲＮＡ的存在及复制。９例患者血清标本抗－ＨＣＶ及ＨＣＶＲＮＡ均为阳性，采用高敏感的逆转录一套式ＰＣＲ法测定其外周血单核细胞中ＨＣＶ正、负链ＲＮＡ，结果９例患者外周血单核细胞中７例ＨＣＶ正链ＲＮＡ阳性，３例ＨＣＶ负链ＲＮＡ阳性，证实部分丙肝患者外周血单核细胞中存在ＨＣＶ的复制，表明肝细胞并非为ＨＣＶ感染与复制的唯一场所。
