京剧器乐的听力损伤（附55例调查报告）

本文对从事京剧打击乐的55人（110耳）进行了听力调查及动态观察。利用图表进行对比分析，发现110耳中高频听力损伤89耳，占81％；语频听力损伤32耳，占29.1%；其中伴有高频耳鸣78耳，占70．9％。动态观察30人（60耳），均为永久性听阈阈移。高频听力损伤最早出现的频率是4kHz，并见典型“V”谷，符合噪声性聋的诊断。     

Clinical characteristics of patients in studies of left ventricular dysfunction (SOLVD).

The Studies of Left Ventricular Dysfunction (SOLVD) trials were designed to evaluate the effects of enalapril on long-term mortality in patients with severe left ventricular (LV) dysfunction. Patients with LV ejection fractions less than or equal to 0.35 and symptoms of congestive heart failure (CHF) were enrolled in the treatment trial, whereas those with no history of overt CHF and taking no treatment directed for LV dysfunction were enrolled in the prevention trial. The baseline clinical characteristics of SOLVD patients were compared to characterize differences between patients in these 2 separate but concurrent trials. From over 70,000 patients screened with LV dysfunction, 4,228 patients were enrolled in the prevention trial and 2,569 patients in the treatment trial. Ischemic heart disease was the primary cause of LV dysfunction in both prevention (83%) and treatment (71%) trial patients. Prior myocardial infarction was present in 80% of the prevention and 66% of the treatment trial patients (p less than 0.001). In the prevention trial, infarction was recent (less than or equal to 6 months) in 27% patients and remote (greater than 6 months) in 57% patients. Treatment trial patients had proportionately more women (20 vs 13%; p less than 0.001) and non-Caucasians (20 vs 14%; p less than 0.001), as well as the coexisting risk factors of hypertension (42 vs 37%; p less than 0.001) and diabetes (26 vs 15%; p less than 0.001) than did prevention trial patients. Clinical characteristics of patients in both trials were influenced by the gender and race of enrolled patients. Similarly, coronary artery bypass surgery was performed less often in women and non-Caucasians.(ABSTRACT TRUNCATED AT 250 WORDS)     

动态监测胃黏膜内pH值对胆源性胰腺炎外科治疗的价值

目的探讨胃黏膜内pH值对胆源性胰腺炎病情预后评估及在决定手术冶疗中应用的价值。方法对确诊的146例胆源性胰腺炎患者经鼻插入胃黏膜二氧化碳张力计（TRIP-NGS导管）测定胃黏膜内pH值，每隔12小时测定一次，并进行APACHEⅡ评分，将2组数据与外科治疗进行相关分析。结果①pH值变化反映胆源性胰腺炎病情发展变化，与器官衰竭数呈负相关；②外科干预治疗与内科治疗比较差异有统计学意义（P〈0．05）；③pHI〉7．25与pH〈7．25患者开腹手术病死率和细菌培养阳性率比较差异有统计学意义（P〈0．05）。结论pH值对胆源性胰腺炎外科治疗有指导意义。外科处理原则是：①胆道无梗阻，以内科保守治疗为主；②伴胆道梗阻，先行经内镜十二指肠乳头括约肌切开术、经内镜鼻胆管引流术、B超导引引流、腹腔灌洗等，如胆道引流不畅或pH值持续下降，则开腹手术。     

MECHANISM OF FIBROPLASIA IN CHRONIC ACTIVE HEPATITIS AN IMMUNOHISTOCHEMICAL STUDY OF VARIOUS COLLAGEN TYPES, FIBRONECTIN AND LAMININ IN HUMAN LIVER

The cytoplasm of human bile ductule epithelia was found to be Type V collagen positive, demonstrating that the epithelia were able to generate this type of collagen. The ductules proliferated greatly with Type V collagen positive cytoplasm in piece-meal necrosis of chronic active hepatitis (CAH). The capillary-like bile ductules inside human hepatic lobules were identified. Our findings might explain the mechanism of fibroplasia in CAH.     

Point mutation in the parkin gene on patients with Parkinson’s disease

Summary To investigate the distribution of possible novel mutations from parkin gene in variant subset of patients with Parkinson’s disease (PD) in China and explore whether parkin gene plays an important role in the pathogenesis of PD, 70 patients were divided into early-onset group and late-onset group; 70 healthy subjects were included as controls. Genomic DNA from 70 normal controls and from those of PD patients were extracted from peripheral blood leukocytes by using standard procedures. Mutations of parkin gene (exon 1–12) in all the subjects were screened by PCR-single strand conformation polymorphism (SSCP), and further sequencing was performed in the samples with abnormal SSCP results, in order to confirm the mutation and its location. A new missense mutation Gly284Arg in a patient and 3 abnormal bands in SSCP electrophoresis from samples of another 3 patients were found. All the DNA variants were sourced from the samples of the patients with early-onset PD. It was concluded that Parkin point mutation also partially contributes to the development of early-onset Parkinson’s disease in Chinese.

Objectively measuring physical ability in elderly persons: the Physical Capacity Evaluation.

The Physical Capacity Evaluation, a performance measure of functional capabilities comprised of 13 tasks simulating those used in activities of daily living, was tested on 289 community-dwelling elderly people and compared against a widely used self-report measure of function, the Health Assessment Questionnaire. Factor analysis identified one dominant component in each instrument. Internal consistency reliability (Cronbach's alpha) was .90 for both instruments. Global disability (Health Assessment Questionnaire) and function (Physical Capacity Evaluation) scores were correlated -.74. One-week retest reliabilities on 58 subjects were .94 for the Physical Capacity Evaluation and .95 for the Health Assessment Questionnaire. The Physical Capacity Evaluation is a valid and reliable measure of physical performance for use with elderly people.     

我省流通领域阿莫西林制剂质量现状

目的:了解流通领域中阿莫西林制剂的质量状况。方法:在全省各市县的部分医药经营企业,抽取阿莫西林胶囊及干糖浆共54批样品,按国家药品标准进行全检后,对其检验结果进行统计分析。结果:不合格的项目有含量、胶囊剂溶出度、干糖浆粒度。该药物制剂的标示百分含量普遍偏低。结论:影响该产品质量的主要项目是含量和溶出度,含量偏低的主要原因是厂家的低限投料,应予以充分重视。
