华支睾吸虫对自然感染动物模型猫肝脏/胆管及生理生化指标的影响

目的 了解自然状态下猫感染华支睾吸虫的现状及该病对肝脏／胆管及生理生化指标的影响。方法 观察活猫的精神状态，处死后肝脏形态及切开后的眼观形态；通过病理切片观察肝脏、胆管及胆囊的病理变化；测定血常规及肝脏功能指标。结果 7.3％的肝脏（8／218，218为阳性猫）表面有明显的黄豆粒大小的肿瘤；94％（205／218）的肝脏质地变硬，结缔组织增生；29．8％（25／218）肝脓肿，肝色较黄，小叶结构模糊：54．1％（118／218）胆管内上皮细胞增生，淋巴细胞浸润；感染猫血红细胞显著降低（P〈0．01），血清丙氨酸氨基转移酶显著升高（P〈0．05）。结论 华支睾吸虫对肝脏、胆管及胆囊造成了严重伤害，很可能是肝癌、胆管癌的诱因之一。     

门诊抗菌药物使用调查

目的了解医院门诊抗菌药物应用情况，为临床合理应用抗菌药物提供依据。方法抽查2006年1月至11月份门诊处方18163张，统计抗菌药物使用情况，并评价其合理性。结果含抗菌药物处方5809张，占总处方数31．98％。头孢菌素类药物使用率最高，其次为喹诺酮类。给药途径主要为口服给药。结论抗菌药物应用基本合理，但使用中存在一些问题，应引起重视。     

Clinical and immunological effects of azithromycin in Behçet''s disease

Background: The aim of this study was to evaluate the effects of azithromycin on mucocutaneous manifestations, oral health and immune response in Behçet's disease (BD). Methods: Eight BD patients with active mucocutaneous symptoms were treated with azithromycin for 4 weeks. Oral health, clinical manifestations and in vitro interleukin (IL)‐12, interferon (IFN)‐γ, IL‐10 and monocyte chemotactic protein (MCP)‐1 responses were evaluated before and after treatment. Results: The number of folliculitic lesions, healing time of oral ulcers and scores of plaque indexes (PLIs) were lower after azithromycin treatment (P < 0.05). Scores of PLIs correlated positively with the healing time of oral ulcers (P = 0.02). Although a trend towards increased stimulated IL‐10 responses with azithromycin was observed, no statistically significant difference was found. Stimulated and unstimulated MCP‐1, IFN‐γ and IL‐12 responses were similar before and after treatment (P > 0.05). Conclusion: Azithromycin was observed to be effective in decreasing folliculitic lesions and fastening the healing time of oral ulcers in BD.     

北京市城市社区老年人伤害疾病负担的研究

目的 探讨北京市城市社区老年人伤害发生现状及其疾病负担。方法 以居委会为单位，采取随机整群抽样的方法，调查北京市牛街地区60岁及以上老年人在其过去一年中的受伤情况及伤后影响等。结果 被调查者在过去一年中共有311例、420人次伤害发生，涉及12种伤害。伤害总发生率（人）为13．55％，人次发生率为18．30％。因伤死亡1例。伤害的危害涉及个人、家庭、社会三个层面，包括躯体、精神、经济损失等多方面。跌倒不仅发生率最高，伤情最严重，而且经济损失最大。结论 北京市城市社区老年人群伤害发生与死亡水平位居中等水平；跌倒已经成为威胁该人群生存与健康的重要公共卫生问题。

从热、虚、瘀三个方面论述了小儿过敏性紫癜的病因病机特点，抓住病因病机的核心，确定了热伤血络、阴虚火旺、气不摄血三个本证证型和风热、热毒、湿热、血瘀四个标证证型。采用本证和标证相结合的方法对小儿过敏性紫癜进行辨证论治，并从理论上探讨了该方法的科学性和实用性。     

健脾止泻饮治疗糖尿病腹泻32例观察

目的:观察自拟健脾止泻饮治疗糖尿病腹泻的临床疗效。方法:治疗组32例用健脾止泻饮治疗,对照组30例用维生素B1、复方苯乙呱啶、盐酸黄连素治疗。结果:治疗组总有效率93.8%,对照组总有效率56.7%,两组比较有极显著性差异(P<0.01)。结论:健脾止泻饮治疗糖尿病腹泻有较好疗效,且无不良反应和毒副作用。     

Regulation of fluid intake in dogs following water deprivation

Whereas water loss in land living animals occurs continuously, water intake takes place discontinuously. At the normal operating set point of plasma osmolality, urine is more concentrated than plasma due to secretion of vasopressin. Thus animals operate around a state of mild dehydration. As water loss occurs, the severity of dehydration and thirst increase in intensity and at some point water intake occurs. Sufficient water is consumed to return plasma osmolality to the normal operating set point. Food intake and water balance are interdependent as food provides the osmoles which determine obligatory renal solute excretion. When dry food with the same osmotic content was substituted for canned food (water content 74%), dogs increased water intake from 24.2 +/- 4.3 to 62.2 +/- 8.8 ml/kg. Urine output and urine osmolality were unchanged, as under conditions of normal hydration, near maximal urine concentration is achieved. Changing water intake is the only available variable to maintain water balance. During water deprivation, the major renal mechanism appears to be natriuresis. In rehydration, satiety mechanisms ensure appropriate water intake and renal sodium conservation restores sodium balance.     

甘南州合作地区藏汉学生个性特征及其影响因素的初步探讨

对生长在合作地区的955名藏、汉族学生进行了个性特征及其影响因素的调查探讨。结果表明:本民族间男、女生E分比较,男生低于女生,显示女生性格较男生性格外向倾向性大。稳定性方面女生N分高于男生,即女生情绪一般不及男生稳定。此外与该地区藏汉族学生个性特征关系较为密切的因素是:兄弟姐妹数、父母亲文化程度、职业以及学前教育和智商。
