dC14可抑制小鼠SRS腹水瘤的发病和生长

作者曾经体外实验证明,均聚寡脱氧胞嘧啶核苷酸片段(dC14)有抗病毒活性,现继续研究其在体内的作用。不给dC14的对照组小鼠,接种腹水瘤细胞后:100％发病和死亡,潜伏期为6d,存活期11d;给每只小鼠dC14 1.3～3.2 mg,发病率和死亡率降低至20％,疾病潜伏期和存活期推迟。在未经dC14处理的种瘤细胞和淋巴组织与经处理的淋巴组织中,多聚酶链反应(PCR)法都检测到病毒核酸,而正常小鼠中则无此种病毒核酸顺序。研究结果提示,dC14对小鼠SRS腹水瘤的发病和生长有抑制作用。此种抑制作用可能是通过抑制病毒基因的表达来实现的。     

甲型流感病毒治疗S37腹水瘤小鼠的实验研究

甲型流流感病毒鼠肺适庆型７５－３９株治疗Ｓ３７腹水型荷瘤小鼠，存活率达９３．３％。体外实验观察流感病毒感染Ｓ３７肿瘤细胞，到３天时Ｓ３７细胞经胎盘蓝染色，１００％的Ｓ３７细胞死亡，而对照组肿瘤细胞染色率只有１０％左右。     

Endoscopic laser pancreatic cystogastrostomy

Traditionally the drainage of pancreatic pseudocysts has been carried out operatively, forming a cystenterostomy. A simple endoscopic method of forming a pancreatic cystogastrostomy with laser is presented. This procedure does not require a general anesthetic, is safe, and allows resolution of symptoms.     

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％。     

儿童原发性单纯性肾病综合征患者白细胞介素4及IgE水平的相关性

本文报道应用抗人 IL-4McAb 及 PcAb 建立了双抗体夹心检测人 IL-4ELISA 法.对20例原发性单纯性肾病综合征患者、16例相应年龄组健康儿童及6例非肾病综合征患儿进行了 IL-2,IL-4 及 IgE水平的测定,并分析了 IL-4及 IgE 的相关性.结果表明,健康儿童 IgE 水平为50-100U/ml,IL-4水平为400-500pg/ml;肾病综合征患儿 IgE 水平为300->1000U/ml,IL-4水平为1080-4000Pg/ml.患儿 IgE 水平的升高与 IL-4水平的升高呈正相关,R 值为0.691.     

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。
