小儿肾小球疾病血清微量元素测定与分析

采用原子吸收分光光度法,测定了７８ 例肾小球疾病患儿血清铜、锌、铁、镁４ 种元素。结果显示,单纯性肾病组、肾炎性肾病组、紫癜性肾病组及肾炎组血清锌均显著低于正常组（ Ｐ＜ ００５）,血清铁、镁与正常组比较无显著差异。单纯性肾病组,肾炎性肾病组血清铜显著低于正常组（ Ｐ＜ ００５）。提示血清铜、锌、铁、镁含量的变化与疾病发生和疾病状态有关。     

The organizational context of non-lethal workplace violence: its interpersonal, temporal, and spatial correlates.

This article examines 993 violent incidents involving faculty, students, and staff that occurred at a highly ranked teaching and research university and its affiliated medical center. Violent incidents were included in the sample if they involved faculty, students, or staff, regardless of their specific location or context (i.e., whether they occurred on campus and/or off-campus and whether they occurred within the context of work or some other activity). The theoretical goal of the project was to compare work-related incidents with non-work-related incidents of interpersonal violence occurring in a single, multifunctioning, and professionally hierarchical organization. Data were collected over a 7-year period from three police departments (city, county, and university), university records, and criminal history records obtained from the state police. The coding protocol was developed to capture crime-scene information pertinent to each of the incidents. This included information about the victim, the perpetrator, the relationship between the victim and perpetrator, and the violent incident. The data were examined using nonparametric statistics and logistic regression to model predictive differences between the workplace and non-workplace incidents. The results suggest that the workplace incidents of violence differ from the non-workplace incidents according to their time, victim age, degree of victim injury, and whether the workplace is a medical location. The authors conclude that these differences are better explained by the movement of people in and out of the workplace who bring societal violence with them, rather than by a category or type of workplace violence.     

Diagnostic criteria for malignancy in bile cytology and its usefulness

Fifty three bile specimens from 42 patients were reviewed to assess the diagnostic role of the bile cytology and to define more reliable cytologic indicators of malignancy. Forty three bile specimens came from 34 patients with malignant biliary strictures and 10 bile specimens were from eight patients with benign conditions. There were no false positives. The diagnostic specificity of bile cytology was 100% while diagnostic sensitivity was 55.8%. Overall diagnostic accuracy was 64.2%. We identified four key criteria as cytologic indicators of malignancy among 20 variables by using multiple regression analysis: loss of honeycomb arrangement, hyperchromatism, increased N/C ratio, and coarse chromatin. When bile specimens with three or more of these four criteria are thought to represent malignancy, the sensitivity of diagnosis of malignancy was 65.2%, specificity was 90% and diagnostic accuracy was 69.8%.     

氧化铝颗粒大小对PEO—NaSCN络合物电导率的影响

研究分散第二相Ａｌ２Ｏ３的含量及颗粒大小对ＰＥＯ－ＮａＳＣＮ络合物电导的影响,结果表明：当颗粒度为０．７μｍ时,电导率比纯ＰＥＯ－ＮａＳＣＮ提高了一个半数量级。颗粒度较大时,电导率均比纯ＰＥＯ－ＮａＳＣＮ低,并在ｗＡｌ２Ｏ３＝０．２５时,存在电导率最大的峰值。     

从中医理论探索方药的作用机理

主要以所承担过的科研课题的研究思路及研究结果为依据,论述从传统中医理论探索方药作用机理的重要性。文中从养阴生津方药治疗热瘀证的作用、血分证中运用活血化瘀法的作用、辛开苦降法的作用及解表法的作用等方面论述从中医的特有理论出发,可以在探索方药作用机理时提供思路、开拓新的研究领域。同时,中医传统证治理论也要不断发展、提高,在运用传统证治理论研究方药作用机理时,不能完全被其所束缚,随着对证治理论认识的发展,对方药作用机理的认识也必然会出现一个飞跃。
