血浆髓过氧化物酶在急性冠脉综合征中的临床意义

目的：探讨血浆髓过氧化物酶（MPO）在急性冠脉综合征（ACS）中的临床意义。方法：分别测定ACS（54例）、稳定型心绞痛（SAP，54例）和对照组（54例）3组患者的血浆MPO、血清高敏C反应蛋白（hsCRP）、肌钙蛋白I（cTnI）浓度，比较各组的差异；所有患者常规治疗，随访半年，记录心脏事件。结果：ACS组血浆MPO浓度明显高于SAP组和对照组患者（P〈0.01），SAP组与对照组之间差异无统计学意义（P=0．74）；ACS组患者血浆MPO与hsCRP，cTnI及心血管传统危险因素无相关性，多元logistic回归分析发现血浆MPO、空腹血糖和性别是ACS诊断的影响因素；高浓度血浆MPO患者心脏事件发生率较高。结论：血浆MPO可能是ACS的生化标志物之一，可预报心脏事件的发生。

Low dose gossypol for male contraception

Aim: To ascertain whether the side effects of gossypol, hypokalemia and irreversibility, could be avoided on dose re-duction. Methods: Seventy-seven male volunteers were divided into 3 groups: control (22 cases), 10 mg gossypol(29 cases) and 12.5 mg (26 cases). Serum levels of testosterone, FSH and LH were measured by RIA and potassiumby flame photometry. Spema counts and motility were examined before and regularly after treatment for the evaluationof contraceptive efficacy. Results: The average sperm density and motility started to decrease significantly by theend of month 2 of medication and gradually reached the infertility levels ( < 4 million /mL) in both treated groups. Af-ter that the 10 mg group was asked to take the same dose every other day for up to a total observation period of 16-18months for the maintenance of infertility. Subjects in the 12.5 mg group did not take gossypol any more so as to ob-serve the length of the loading dose required, but in a few, a maintenance dose of 12.5 mg every     

Active and passive smoking and the risk of stomach cancer, by subsite, in Canada.

This study assessed the influence of active and passive smoking on the risk of stomach cancer by subsite. Mailed questionnaires were used to obtain information on 1171 newly diagnosed histologically confirmed stomach cancer cases and 2207 population controls between 1994 and 1997 in eight Canadian provinces. Data were collected on socio-economic status, lifestyle and passive smoking status. Odds ratios (OR) and 95% confidence intervals (95% CI) were derived by logistic regression. Compared with those who had never smoked, there was strongly increased risk for ex- and current smokers among subjects with cardial stomach cancer. For men with cardial cancer, the adjusted ORs were 1.9 (95% CI 1.2-3.0) and 2.6 (95% CI 1.6-4.3) for ex-smokers and current smokers, respectively, with a similar pattern among women. Among men, the adjusted ORs were lower for subsites of stomach cancer other than cardia. These findings suggest that active and passive smoking may play an important role in the development of cardial stomach cancer.     

EVALUATION OF THE PROGNOSTIC VALUE OF nm23 GENE EXPRESSION IN BREAST CANCER

Mortality of breast cancer is almost due to subsequent metastases, but the micrometastasis is difficult to be detected. Early diagnosis of distant metastasis is a key to improve prognosis of breast cancer. The nm23 gene is a putative metastasis suppressor gene originally identified in murine melanoma cells. The purpose of this study was to investigate the relationship between nm23 gene expression (mRNA and protein) and distant metastasis of breast cancer. MATERIALS AND METHODS Pati…     

肾移植患者细菌谱的调查及耐药性的研究

目的：通过调查研究肾移植患者常见致病菌株分布特点及其对抗生素敏感性的规律，进一步提高临床治疗肾移植后感染患者的成功率。方法：1997年4月－2000年5月间，对拟诊为呼吸系和／或泌尿系细菌感染的肾移植患者进行，取其痰，咽拭子或中段尿标本进行细菌培养并作24种常用抗生素药敏试验，对结果进行统计学分析。结果：共有653份标本培养结果阳性，其中痰标本233份，咽拭子173份，中段尿247份，主要阳性菌株是铜绿假单胞菌，肺炎克雷伯杆菌，大肠杆菌和表皮葡萄球菌等。敏感率较高的抗生素有万古霉素，亚胺培南，阿米卡星和头孢他啶等，耐药率较高的有青霉素，氨苄西林，红霉素，苯唑西林和头孢唑林等。结论：（1）肾移植后感染的主要菌株种类与其他患者有所不同；（2）肾移植患者的感染菌株对抗生素敏感率最高的依次为万古霉素，亚胺培南，阿米卡星和头孢他啶，但耐药性也正在逐渐增强（3）肾移植患者的感染主要发生在呼吸和泌尿系统，其他部位的感染少见；（4）痰和咽拭子来源的细菌株对抗生素更敏感，中段尿来源的细菌则耐药株相对多见。
