防治口腔疾病对老年人的健康尤为重要,老年人的口腔卫生保健应注意以下几个方面：早期防治龋病（根面龋）、牙齿磨损、牙周疾病、黏膜疾病、牙列缺损、缺失等。     

开放式吸痰法对肺不张患者呼吸循环参数的影响

目的研究开放式吸痰法对肺不张患者呼吸循环参数的影响。方法选择11例肺不张并机械通气的危重患者,观察吸痰前1min及吸痰后3、20min患者的呼吸(RR)、心率(HR)、收缩压(SBP)、舒张压(DBP)、脉搏血氧饱和度(SpO2)、气道峰压(Ppeak)、平台压(Pplat)和潮气量(VT)情况。结果与吸痰前1min相比,吸痰后3min的SBP、HR、RR、Ppeak、Pplat均显著增高(<0.05),SpO2显著下降(<0.05);吸痰后20min,RR仍显著增高(<0.05)。结论开放式吸痰法会明显影响肺不张患者的呼吸循环参数及气道压力的稳定性,对患者病情不利。护理过程中,应重视吸痰引起的继发性损害,加强吸痰前后呼吸循环等参数的监测。     

甘肃天祝白牦牛肉、奶及制品卫生学监测分析

目的：了解白牦牛肉、奶及制品中重金属、食源性致病菌的污染状况,为预防白牦牛食物链系统食源性疾病的发生提供依据。方法：按GB/T5009.11.12.15-2003及GB/T4789.4.5.6.10.30-2003对白牦牛肉、奶及制品中重金属、食源性致病菌进行检测。结果：白牦牛鲜肉及熟肉制品铅、砷、镉未超标;鲜奶及消毒奶铅、镉污染水平高;鲜肉及鲜奶沙门菌、金黄色葡萄球菌检出率高;肉制品及消毒奶沙门菌、金黄色葡萄球菌检出率明显降低。结论：天祝白牦牛肉、奶及制品存在着重金属及食源性致病菌的污染,应引起天祝白牦牛养殖加工行业的重视,预防食源性疾病的发生。     

苦参素的临床及药理研究进展

苦参为豆科植物,其主要成分为苦参素。苦参素是一类含有苦参次碱15酮基本结构的化合物,其中氧化苦参碱含量在98%以上。近年来对苦参的研究甚多,取得了明显成效。众多报道显示,苦参素具有抗菌、抗病毒、抗肿瘤、抗心律失常作用。现笔者将其临床应用及药理研究概述如下。1临床应用1.1心律失常心律失常是心脏传导系统病变,临床上多采取西药治疗。但近年来,对用苦参治疗多种快速心律失常的报道也很多。陈可冀[1]认为苦参抗心律失常作用与奎尼丁类似,治疗期前收缩及快速型心律失常疗效可靠。朱良春治疗心律失常,在辨证用药的同时加用苦参,经临床…

EXPRESSION OF PCNA, AKP AND ACP DURING DEVELOPMENT OF MOUSE FORE STOMACH CARCINOMA

Objective： To find out the relationship of the expressions of proliferating cell nuclear antigen （proliferating cell nuclear antigen, PCNA）, alkaline phosphotase （alkaline phosphotase, AKP） and acid phosphotase （acid phosphotase, ACP） with the development of mouse fore stomach cancerization. Methods： The animal models, including the various stages during the development of NIH mouse fore stomach carcinoma, were made by N-Nitrososarcosineethylester （N-Nitrososarcosineethylester, NSEE）. The mice were sacrificed on the 14th, 28th, 42nd, 56th, 70th and 84th days respectively after mice were irrigated with NSEE. The fore stomach was taken out and dissected. The methods of histopathology, immunohistochemistry and isoenzyme electrophoresis were adopted to study the dynamic changes of cell shape and expression of PCNA, AKP and ACP. Results： On the 42nd and 56th days after NSEE treatment, the expression of PCNA increased gradually along with the cancerization. Comparing with the control, there were significant differences （P〈0.05）. On the 70th and 84th days, the expression of PCNA increased further （compared with the control P〈0.01）. The activity of AKP increased gradually along with the cancerization. On the 14th, 28th, 42nd and 56th days, there were significant differences （P〈0.05）; on the 70th and 84th days, the activity of AKP increased further （P〈0.01）. The activity of ACP also increased on the 14th, 28th, 42nd and 56th days, and there were significant differences on the 70th days （P〈0.05） and on the 84th days （P〈0.01） compared with the control. Conclusion： During the carcinogenesis of NIH mouse fore stomach, the expressions of PCNA, AKP and ACP increased gradually and were consisted with the changes of cell shapes.     

悬浮培养过程中碳、氮、磷的补加对南方红豆杉细胞生长影响的研究

目的：解决南方红豆杉生长缓慢的问题。方法：考察红豆杉细胞悬浮培养过程中磷的消耗，并研究了碳、氮、磷对细胞生长及细胞活性的影响。结果：碳源在悬浮培养中期已经消耗殆尽，后期碳源的缺乏限制了细胞的生长。结论：补加碳源组与对照组相比，细胞生长率和细胞密度明显提高，其中细胞生长率约提高了83％。     

与儿子谈自慰

儿子上初中后，看着孩子快速发育的身体。我还是请先生给儿子单独谈了青春期身体和心理的变化，我想让儿子在这个阶段不要因为发育而带来任何的压力，让他和父亲搭建一个交流的平台，因为孩子的性问题不是一堂课和一本书就完全能够解决的。父亲和儿子谈青春期的问题是最合适不过的了。可先生告诉我．他不知道怎样开口，他说：“你是性教育专家。你去和他谈吧!”一副想推卸的样子。
