古方豨莶丸对膝骨性关节炎模型家兔关节液中IL-1β、TNF-α含量及关节软骨细胞形态学的影响

宋代《证类本草》中收载有一个豨莶丸(即古方豨莶丸),为单一豨莶草的嫩茎叶,经用酒蒸制9次后制备成的蜜丸。豨莶丸最早记载的主治是中风,宋代《南阳活人书》记载:主治风、寒、湿之气,着而成痹,以致血脉凝涩,肢体麻木,腰膝酸痛,二便燥结,无论痛风痛痹,湿痰风热,宜于久服。近代临     

Alcoholism treatment in general hospitals

This article examines recent developments in the role of general hospitals in providing treatment for alcoholism. It employs data on 5,000 U.S. short-term general hospitals and on all patients discharged from a subsample of 400 of these hospitals in the years 1980 through 1985. The article describes the growth in alcoholism treatment resources in short-term hospitals (1980-85) and examines linked hospital and patient data for the 400 hospitals in the subsample to describe patient diagnoses and resource use (1980 and 1985). Patients are classified by the stage of their alcohol problem, and hospital use is examined for patients in different stages.     

Physiologic responses to heavy-resistance exercise with very short rest periods

Heavy-resistance exercise utilizing very short rest periods is commonly used by body builders to prepare for competition. The purpose of this study was to compare the acute responses of this type of heavy-resistance exercise protocol in competitive body builders (BB) and power lifters (PL). Nine male BB and eight PL were matched for age, size and experience. A ten-station heavy-resistance exercise protocol was used. Each subject performed three sets of 10 repetition maximum (RM) with 10-s rest between sets and alternated 30-s and 60-s rest periods between exercises. No differences were observed in total work between the groups, but BB used a significantly (P less than 0.05) higher percentage of their 1 RM in the bench press and leg press exercises. Heart rate, ratings of perceived exertion (RPE), and lactate levels were obtained during the exercise protocol; significant (P less than 0.05) increases were observed above rest for these variables. RPE was significantly correlated with lactate levels (r = 0.84). Plasma epinephrine, norepinephrine, dopamine, cortisol, and lactate levels significantly increased from pre- to 5 min post-exercise. Mean plasma volumes were reduced -16.6 (+/- 3.64)% and -20.6 (+/- 8.32)% following the exercise protocol for BB and PL, respectively. Significant (P less than 0.05) decreases in eosinophil counts were observed following exercise. No significant differences were observed between BB and PL for any of the physiologic responses measured. PL exhibited a higher incidence (100%) of clinical symptoms of dizziness and nausea compared to BB (11.1%).(ABSTRACT TRUNCATED AT 250 WORDS)     

Plasmid profiling of epidemic staphylococci from around 1960: a comparison of epidemiological techniques.

Plasmid profiles have been established for 68 isolates of Staphylococcus aureus from 13 episodes of epidemic spread in hospital wards between 1958 and 1962. Despite the original lack of care in preservation of strains the profiles give, in general, the same epidemiological patterns as were established originally on the basis of phage type, antibiotic sensitivity, ward and date of isolation.     

SLE小鼠高IgG血症Fcgr2b基因序列分析

目的: 测定系统性红斑狼疮(SLE)小鼠模型-NZB/WF1双亲NZB,NZW小鼠 Fcgr2b基因启动子区核酸序列,明确Fcgr2b基因启动子区的突变性质.方法:扩增NZB,NZW小鼠Fcgr2b基因启动子DNA进行核酸序列分析.采用ELISA法测定、比较(NZB×NZW )F1×NZW回交小鼠Fcgr2b基因B/W型与W/W型组间血清总IgG 水平.结果:NZB小鼠Fcgr2b基因启动子区与正常鼠Balb/C相比存在2个部位碱基缺失,分别为13 bp及3 bp.NZW小鼠除有3个碱基置换外,与Balb/C鼠该基因启动子区序列相同.回交小鼠Fcgr2b基因B/W型组血清总 IgG水平明显高于W/W型组(P<0.0001).结论:NZB小鼠Fcgr2b基因启动子区存在碱基缺失,且该缺失突变可能与血清总IgG水平升高有关.

经尿道膀胱肿瘤切除专用手术刀具的临床应用

目的对经尿道膀胱肿瘤切除专用手术刀具治疗浅表性膀胱肿瘤进行临床应用评价。方法在传统电切刀的远端添加保护襻组成膀胱肿瘤切除专用手术刀具。使用该种手术刀具治疗浅表性膀胱肿瘤48例,使用方法与普通电切刀近似。男26例,女22例。年龄23~76岁,平均43岁。肿瘤分期Tis者1例,T0~T1者47例。肿瘤分级G1~G2者36例,G3~G4者12例。瘤体直径0.5~8.0 cm。肿瘤位于膀胱顶部4例,左侧壁11例,右侧壁9例,前壁4例,后壁13例,颈部7例。肿瘤单发31例,多发17例。术后常规卡介苗膀胱灌注1年,每3个月行膀胱镜检查1次。结果48例平均手术时间(23±10)m in。术中18例(37.5%)发生闭孔神经反射,未出现膀胱穿孔病例;无瘤体后部的正常膀胱黏膜误切。46例术后随访1年,14例复发,均为远位新生膀胱肿瘤,术后3个月时发现1例,4~6个月时3例,7~9个月时6例,10~12个月时4例。结论使用该专用手术刀具治疗浅表性膀胱肿瘤容易控制切除深度,可最大限度地避免膀胱穿孔,并可保护大体积肿瘤后部盲区的正常黏膜以免误切。     

Maculopathy caused by intra-arterially administered cisplatin and intravenously administered carmustine.

Eight patients with malignant gliomas were monitored with clinical examinations to study the effects of the combination of intravenous administration of carmustine and infraophthalmic intra-arterial administration of cisplatin on retinal and optic nerve function. Three patients developed a severe macular retinal pigment abnormality in the eye ipsilateral to the intra-arterial infusion. Electrophysiologic studies disclosed no evidence of a generalized disturbance in the photoreceptors, middle retinal layers, or retinal pigment epithelium. In contrast to previous studies involving patients whose visual loss was caused by vaso-occlusive lesions in the retina and optic nerve, our study involved patients with clinically significant maculopathy, that was not vascular in origin and that developed after treatment with carmustine and cisplatin. We suggest that the deficit may result from a localized retinal pigment disturbance in the macula.
