新疆乌鲁木齐县农村住宅卫生设施状况的调查与评价

本文报告了乌鲁木齐县两种不同类型住宅的卫生设施状况，重点对上下水设施，厕所及周围卫生状况进行了调查。结果表明：小二楼住宅有给排水设施及卫生间；砖土木结构平房内只有上水（自来水），但无下水道及卫生间。因均饮用城市自来水，故两类住宅人群肠道传染病发病率无显著性差异（Ｐ＞０．０５）。对Ｂ村六年几种肠道传染病发病率的动态分析表明，改水是预防和降低肠道传染病发病的有效措施。调查结果还表明，住宅设施完善与否，     

Coplanar PCBs in fish and mussels from marine and estuarine waters of New York State.

Thirty samples of striped bass from marine and estuarine waters of New York State, six samples of mussels from Long Island Sound, and one composite sample of freshwater mussels from Troy were analyzed by a recently developed method which combines sulfuric acid cleanup, carbon chromatography, and high-resolution gas chromatography for the determination of non-ortho- and mono-ortho-substituted polychlorinated biphenyls (PCBs), which are biologically active congeners of PCBs and approximate isostereomers of 2,3,7,8-tetrachlorodibenzo-P-dioxin of (2,3,7,8-TCDD). Non-ortho coplanar PCBs ranged from 0.2 to 37.1 ppb in fish. The highest concentrations of 37.1 ng/g of 3,3',4,4'-tetrachlorobiphenyl (77) and 7.5 ng/g of 3,3',4,4',5-pentachlorobiphenyl (126) were detected in a fish caught near Troy/Albany, New York. Mono-ortho-substituted PCBs ranged from 0.4 to 790 ppb in fish, with the major components identified as 2,3',4,4',5-penta-(118) and 2,3,3',4,4'-pentachlorobiphenyls (105). When concentrations were converted to 2,3,7,8-TCDD picogram equivalents, 99% of the equivalents were derived from three congeners (77, 105, and 126), 3,3',4,4',5-pentachlorobiphenyl (126) accounting for approximately 80% of the activity. At Troy pg/g TCDD equivalents derived from PCB were approximately 3000, whereas the actual 2,3,7,8-TCDD concentration was only 20 pg/g; hence, accurate coplanar PCB measurement is important.

Promoting effect of the Chinese medicinal herb, wikstroemia chamaedaphne and tung oil extracts on carcinoma of the uterine cervix induced by HSV-2 or methylcholanthrene (MCA) in mice

The promoting effect of the Chinese medicinal herb, Wikstroemia chamaedaphne and Tung oil extracts (WC and HHPA) on carcinoma of uterine cervix induced by HSV-2 or MCA in mice was studied. The results showed that WC and HHPA extracts were not carcinogenic themselves. After carcinogen HSV-2 and MCA treatment, WC and HHPA were added separately. The inducing rates by HSV-2 increased from 7.4% to 21.1% and 26.3%, those by MCA increased from 56.5% to 82.8% and 84.4%. There was a significant difference between the combined groups and groups with HSV-2 or MCA only. The experimental results suggest that these two kinds of extracts play a promoting effect on carcinogenesis. The relation between the carcinogenesis of uterine cervix or nasopharynx and WC or HHPA extracts is discussed.     

Association of the GNAS1 gene variant with hypertension is dependent on alcohol consumption.

The beta-adrenoceptor (beta-AR)-stimulatory guanine nucleotide-binding (Gs) protein system has been shown to play important roles in the cardiovascular system. The gene encoding the alpha-subunit of Gs proteins (GNAS1) is a candidate genetic determinant for hypertension. Because alcohol consumption is known to affect blood pressure partly through the beta-AR-Gs protein system, we examined the possible interaction between GNAS1 T393C polymorphism and drinking status in the association with hypertension in the present study. As a result, a non-significant but reasonable trend supporting the presence of an interaction was shown (p = 0.076). In line with this trend, the T393C polymorphism significantly interacted with drinking status in the association with systolic blood pressure (p = 0.028). Moreover, supporting the presence of an interaction, T allele carriers consistently had a higher probability of hypertension, higher systolic blood pressure, and higher diastolic blood pressure than CC homozygotes in non-drinkers and light drinkers. In contrast, CC homozygotes consistently had a higher probability of hypertension, higher systolic blood pressure, and higher diastolic blood pressure than T allele carriers in moderate to heavy drinkers. The present study also showed a significant interaction between the T393C polymorphism and drinking status in the association with pulse pressure (p = 0.026), reflected by a significant association between the T393C polymorphism and pulse pressure in moderate to heavy drinkers (p = 0.026). These findings may be helpful in conducting further molecular and biological studies on the relationship among the effects of alcohol, the beta-AR-Gs protein system, and hypertension.     

调气活血汤治疗崩漏34例

崩漏是月经周期、经期、经量严重失常的病证，是指经血非时暴下不止或淋漓不尽而言。调气活血汤为韩百灵氏治疗崩漏之经验方，韩氏认为本方证多由情志不遂，积思郁怒，或经产后，余血未尽，感寒涉水，过食生冷，不禁房事，余血停滞，瘀阻冲任，心血不得归经，而致崩中漏下。临证时须审因论治，若气病及血者，以活血为主，调气为辅。笔者自2005年以来，运用本方治疗妇女崩漏病34例，取得满意疗效，现报道如下。
