胃镜和肝胆B超检查可以同一天作吗

柯大夫：我有胃溃疡病史，因此每次体检时，都会要求医生帮我作胃镜检查。有一次，我作完胃镜检查以后，就去作肝胆B超检查，B超医生说看不清楚，因为两个检查都要求空腹，建议我最好把这两个检查分开两天作。可是这样，我就要用两天时间来体检，很不方便。请问，胃镜检查和肝胆B超检查真的不能同一天作吗？

Mantel-haenszel statistics and direct standardization

This paper demonstrates that the Mantel-Haenszel chi-square statistic may be employed to test the equality of two directly standardized rates. For certain epidemiological applications, this eliminates the need for special computer programs to contrast two directly standardized rates. Furthermore, since the weights are determined entirely by the data there is the advantage of avoiding the selection of an external standard population. Data analysts who compare two groups of rates with the Mantel-Haenszel chi-square statistic may view this statistic as a comparative measure of two directly adjusted rates.     

两种片形吸虫鉴别与比较

本文利用形态分类学方法、生活史培养、染色体和同工酶分析，系统地描述两种片形吸虫的可比特征。提出在种类鉴别上较直观、不易混淆的分类特征。肝片吸虫成虫的形态与巨片吸虫除大小不同外，更明显的不同是成虫的前部和后端及虫体长宽比，腹吸盘直径与口吸盘直径比等方面。生活史培养中各期虫体的形态与发育时间也表现出很大的不同。染色体比较分析说明肝片吸虫与巨片吸虫为同源三倍体和同源二倍体。同工酶分析显示两种吸虫的酯酶同工酶相同．过氧化物酶在种类鉴别上有意义。     

德阳地区妇女“两癌”防治知识知晓现状及影响因素分析

目的 调查德阳地区妇女乳腺癌和宫颈癌（简称“两癌”）防治知识的掌握情况,探讨影响女性“两癌”防治知识认知的相关因素,为更好地开展 “两癌”筛查工作提供参考依据。方法 采用分层整群抽样方法于2019年6—9月抽取德阳市妇女作为研究对象进行“两癌”防治知识知晓情况现场问卷调查,采用描述流行病学分析方法进行分析,并采用单、多因素分析方法对“两癌”防治知识知晓影响因素进行分析。结果 共对1 835名德阳市女性居民进行分析,年龄20~69岁,平均（42.36±5.22）岁。文化程度以初中（653人,35.59%）和高中（634人,34.55%）为主。城镇居民占60.60%。职业以企事业职工为主（594人,32.37%）。“两癌”防治知识的总均分为（23.6±5.3）分,总知晓率为49.30%。答对“两癌”防治知识问卷60%以上题的有878人,了解率为47.85%。年龄越大（OR=0.730）的女性居民“两癌”防治知识了解的可能性较小,文化程度越高（OR=2.787）、居住地在城镇（OR=5.512）、职业为企事业单位职工或个体户（OR=5.124、1.713）、家庭人均月收入越高（OR=2.298）、乳腺疾病史（OR=1.775）和妇科疾病史（OR=1.320）是女性“两癌”防治知识了解率的促进因素。结论 德阳市适龄妇女“两癌”防治知识的掌握情况不佳,应重点针对高龄、文化程度低、农村地区的低收入女性人群加强“两癌”健康知识宣传教育工作。

Poland and US collaborative study on cardiovascular epidemiology. I. Introduction and baseline findings

The Poland-US Agreement for Health Cooperation has as its goal the sharing of scientific information in cardiovascular disease epidemiology between the two countries. Patterns of cardiovascular disease and identification of risk factors were investigated through two large epidemiologic studies, the Pol-Monica Study in Poland and the US Lipid Research Clinics Program Prevalence Study in the United States. These two studies are described with regard to methodological issues, comparability of data collection procedures, and demographic and behavioral characteristics of the two populations involved. Mean blood pressure, lipids, and body mass indices of participants in these studies are also compared.     

Mortality and temperature in Sofia and London

STUDY OBJECTIVE: Heat and cold have been associated with increased mortality, independently of seasonal trends, but details are little known. This study explores associations between mortality and temperature in two European capitals-Sofia and London-using four years of daily deaths, air pollution, and weather data. DESIGN: Generalised additive models were used to permit non-linear modelling of confounders such as season and humidity, and to show the shape of mortality-temperature relations-using both two day and two week average temperatures separately. Models with linear terms for heat and cold were used to estimate lags of effect, linear effects, and attributable fractions. PARTICIPANTS: 44701 all age all cause deaths in Sofia (1996-1999) and 256464 in London (1993-1996). Main results: In London, for each degree of extreme cold (below the 10th centile of the two week mean temperature), mortality increased by 4.2% (95% CI 3.4 to 5.1), and in Sofia by 1.8% (0.6 to 3.9). For each degree rise above the 95th centile of the two day mean, mortality increased by 1.9% (1.4 to 2.4) in London, and 3.5% (2.2 to 4.8) in Sofia. Cold effects appeared after lags of around three days and lasted-particularly in London-at least two weeks. Main heat effects occurred more promptly. There were inverse associations at later lags for heat and cold in Sofia. CONCLUSIONS: Average temperatures over short periods do not adequately model cold, and may be inadequate for heat if they ignore harvesting effects. Cold temperatures in London, particularly, seem to harm the general population and the effects are not concentrated among persons close to death.     

Test models for hygienic handrub and hygienic handwash: the effects of two different contamination and sampling techniques.

Two methods for artificial contamination of hands and two sampling techniques to recover the test organisms were compared for their effects on the results of two post-contamination hand treatments: a handrub with two portions of 3 ml of 2-propanol 60% v/v for 1 min, and a handwash with liquid soap 20% w/v for 1 min followed by a 15 s rinse. The two contamination methods involved a short immersion of the hands (up to the middle of the mid-hand) in a suspension of the test organism followed by either air-drying (3 min) or drying by rubbing the hands' vigorously against each other (3 min) in a standardized way. The two sampling techniques consisted of rubbing the fingertips in either 10 ml trypticase soy broth (TSB) against the bottom of a Petri dish; or 100 ml TSB against glass beads contained in a bowl. Sixteen volunteers were randomly allotted to four blocks of four. They carried out the four possible combinations of two treatments and two contamination methods in a series of four tests arranged in a Latin-square design. In addition, the two sampling techniques were compared with each other concurrently by sampling of the right and left hand each with a different one of the two techniques. The alcoholic handrub reduced the release of test organisms significantly (2P less than 0.005) more effectively, by 1.1-1.3 x log10, than did the handwash with liquid soap, regardless of the contamination or sampling method. Whereas the two recovery techniques yielded virtually identical results in corresponding situations, the method of artificial contamination affected the mean reduction factors, strongly.(ABSTRACT TRUNCATED AT 250 WORDS)
