174例不孕妇女生殖道病原体DNA检测及分析

目的了解拟接受体外受精及胚胎移植技术(IVF-ET)前的不孕妇女生殖道淋病奈瑟菌(NG)、解脲支原体(UU)和沙眼衣原体(CT)的感染情况。方法应用荧光定量PCR法对174例拟接受IVF-ET前的不孕妇女及69例早孕对照组妇女进行NG、UU、CT-DNA的检测。结果不孕组与对照组淋病奈瑟菌检出率均为0;解脲支原体的检出率不孕组低于对照组,分别为551%和739%,有显著性差异(P<001);沙眼衣原体的检出率分别为28%和0,有显著性差异(P<005);解脲支原体和沙眼衣原体的混和感染检出率分别为28%和0,有显著性差异(P<005)。结论接受IVF-ET前对不孕妇女进行NG、UU、CT-DNA的常规检测有较高的价值。淋球菌和沙眼衣原体在不孕症患者中的检出率较低,解脲支原体在不孕症与早孕中都有很高的检出率,是否和不孕存在密切关系有待进一步研究。

孕妇性病病原体感染情况分析

目的 探究上海市普陀区孕产妇生殖道衣原体、淋病奈瑟菌和支原体感染情况，为该地区孕产妇生育中和孕前性病病原体的防控提供参考意见。方法 对上海市普陀区妇婴保健医院2017年—2021年产科门诊孕产妇进行沙眼衣原体、淋病奈瑟菌、支原体检测，对检测结果进行分析，了解这3种性传播疾病在孕产妇中的感染情况。结果 在16 875例孕妇阴道分泌物标本中，共检出855例沙眼衣原体，18例淋球菌，8 503例解脲支原体感染，1 287例人型支原体。沙眼支原体的感染率为5.07%,淋球菌的感染率为1.07‰,解脲支原体的感染率为50.39%,人型支原体的感染率为7.63%。结论 目前上海市普陀区孕产妇支原体中以解脲支原体感染率较高，支原体感染可以考虑使用强力霉素和美满霉素，为避免临床耐药株的出现，需要根据药敏结果合理应用抗生素。沙眼衣原体感染率先降低再升高，沙眼衣原体的治疗目前采用阿奇霉素1 g/顿服，效果较好。淋球菌感染目前处于较低水平，治疗以头孢类抗生素使用为优先，从优生优育角度考虑，仍需要继续对孕产妇监控，防止性传播疾病发生。

Heat-related illnesses, deaths, and risk factors--Cincinnati and Dayton, Ohio, 1999, and United States, 1979-1997

During the summer of 1999, a heat wave occurred in the midwestern and eastern United States. This period of hot and humid weather persisted from July 12 through August 1, 1999, and caused or contributed to 22 deaths among persons residing in Cincinnati (18 deaths) and Dayton (four deaths). A CDC survey of 24 U.S. metropolitan areas indicated that Ohio recorded some of the highest rates for heat-related deaths during the 1999 heat wave, with Cincinnati reporting 21 per million and Dayton reporting seven per million (CDC, unpublished data, 1999). This report describes four heat-related deaths representative of those that occurred in Cincinnati or Dayton during the 1999 heat wave, summarizes heat-related deaths in the United States during 1979-1997, describes risk factors associated with heat-related illness and death, and recommends preventive measures.     

International standards and international reference preparations: amphotericin B, vancomycin, capreomycin, cefalotin, demethylchlortetracycline, gentamycin, gramicidin S, kanamycin and kanamycin B, lincomycin, lymecycline, methacycline, paromomycin, rifamycin SV, ristocetin and ristocetin B, spiramycin, and triacetyloleandomycin

Each of the preparations described here was obtained and evaluated at the request of a WHO Expert Committee on Biological Standardization. Unless otherwise stated, a standard procedure was used to distribute the material into individual ampoules. The procedure was as follows. Upon receipt by the National Institute for Medical Research (NIMR), London, materials were stored temporarily in the dark at a temperature of -10°C or lower, and protected from moisture. At a convenient time they were brought back to room temperature, mixed, and distributed into individual neutral glass ampoules so that each ampoule contained 50-100 mg of powder. If it was known that the material was light-sensitive non-actinic glass ampoules were used. After exhaustive drying in vacuum over phosphorus(V) oxide, the ampoules were either constricted (up to 1963) or fitted with capillary leak plugs, dried for a further period under the same conditions, filled with dry nitrogen, and sealed by fusion of the glass. The total drying period varied from 8 to 38 days according to the nature of the material. After they had been tested for leaks, the ampoules were stored in the dark at -20°C.     

Zinc, copper, and magnesium and risks for all-cause, cancer, and cardiovascular mortality

BACKGROUND: Experimental data suggest that zinc, copper, and magnesium are involved in carcinogenesis and atherogenesis. Few longitudinal studies have related these minerals to cancer or cardiovascular disease mortality in a population. METHODS: Data from the Paris Prospective Study 2, a cohort of 4035 men age 30-60 years at baseline, were used to assess the association between serum zinc, copper, and magnesium and all-cause, cancer, and cardiovascular disease mortality. Serum mineral values measured at baseline were divided into quartiles and classified into low (1st quartile, referent group), medium (2nd-3rd quartiles), and high (4th quartile) values. During 18-year follow up, 339 deaths occurred, 176 as a result of cancer and 56 of cardiovascular origin. Relative risks (RRs) for each element were inferred using Cox's proportional hazard model after controlling for various potential confounders. RESULTS: High copper values (4th quartile) were associated with a 50% increase in RRs for all-cause deaths (RR = 1.5; 95% confidence interval = 1.1-2.1), a 40% increase for cancer mortality (1.4; 0.9-2.2), and a 30% increase for cardiovascular mortality (1.3; 0.6-2.8) compared with low values (1st quartile). High magnesium values were negatively related to mortality with a 40% decrease in RR for all-cause (0.6; 0.4-0.8) and cardiovascular deaths (0.6; 0.2-1.2) and by 50% for cancer deaths (0.5; 0.3-0.8). Additionally, subjects with a combination of low zinc and high copper values had synergistically increased all-cause (2.6; 1.4-5.0) and cancer (2.7; 1.0-7.3) mortality risks. Similarly, combined low zinc and high magnesium values were associated with decreased all-cause (0.2; 0.1-0.5) and cancer (0.2; 0.1-0.8) mortality risks. CONCLUSIONS: High serum copper, low serum magnesium, and concomitance of low serum zinc with high serum copper or low serum magnesium contribute to an increased mortality risk in middle-aged men.     

Psychological distress, gender, and health lifestyles in Belarus, Kazakhstan, Russia, and Ukraine

This paper examines the relationship between psychological distress, gender, and health lifestyles in Belarus, Kazakhstan, Russia, and Ukraine. These countries have been subjected to highly stressful and extensive social change associated with the transition out of communism. Data were collected by face-to-face interviews (n = 10,406) in November 2001. Distress was measured by 12 psychological distress symptoms. Health lifestyles focused on measures of alcohol consumption, smoking and diet. We found that females carried a much heavier burden of psychological distress than males, but this distress did not translate into greater alcohol consumption and smoking for these women or for men. The greatest influence of distress on health lifestyle practices was on daily diets in that both less distressed females and males consumed a more balanced diet than more distressed persons. Our findings suggest that it is the normative demands of a particular lifestyle, rather than distress, that principally shapes the pattern of heavy male drinking. This is an important finding as some sources indicate heavy drinking is largely responsible for the health crisis in the former socialist states.     

Dietary sodium, calcium, and potassium, and blood pressure

The cross-sectional association of systolic blood pressure with dietary sodium, calcium, and potassium, as estimated from dietary histories, was investigated by multiple regression analysis of data gathered in the Netherlands in the early 1950s in a general health examination of 2,291 middle-aged civil servants and spouses of civil servants. A statistically significant negative trend with systolic blood pressure was seen for calcium intake in both males and females, even after adjustments for covariates. For sodium and potassium intake, the observed negative trends were not significant after multivariate analyses. In addition, no consistent associations were found between diastolic blood pressure and the micronutrients after multivariate analyses, except for a significant negative association with calcium intake in females. In this study population, blood pressure was a strong independent risk factor of total mortality: 15- and 25-year mortality was about twice as high for hypertensives (greater than or equal to 160 mmHg) as for normotensives (less than 160 mmHg). These findings support the conclusion in recent epidemiologic studies that higher intakes of calcium are associated with lower systolic blood pressure, and they extend the evidence to an earlier time period.
