六经气津互化论

气与津皆生于水谷,气生于水,水化于气,津即为水。由于气津互化的密切关系,故任何一方的改变,都会影响到另一方,即所谓水化于气,亦能病气;气生于水,亦能病水。因此,太阳经气可概括为两大功能,即卫外和气化,是由气津互化而体现的;阳明气津之间,表现为相互制约;少阳经的气津互化,关系到少阳气机的条达舒畅及三焦水道的通调运使;太阴脾气的健旺,可使津液化生有源;少阴心肾精血充沛,滋养有时,才可使心肾之气化生有源;而厥阴之气的条达顺畅,又可维持津液代谢的平衡状态。     

氧化砷对小鼠腹水型肝癌细胞的作用

目的 :研究氧化砷对移植性腹水型肝癌细胞的抗癌作用。方法 :肝癌细胞 (1 8× 10 7)接种入小鼠腹腔。对照组注射NS(0 8mL) ,余组用氧化砷 (1,2 ,3μmol/L)腹腔注射 ,每日 1次 ,共 10日。结果 :第 10天腹水细胞计数 ,1,2和 3μmol/L组瘤细胞锐减 (P <0 0 5 ) ,但第 16天腹水肿瘤细胞急骤增加。结论 :氧化砷对腹水肿瘤细胞有暂时抑制作用。     

糖耐量试验对评价肝癌患者肝脏储备功能的价值

绝大多数肝细胞性肝癌患者合并肝硬变，为预测其对肝切除的耐受性，给正确选择切肝患者提供依据，作者对６２例切肝者和４９例未切肝者手术前后的糖耐量试验（ＯＧＴＴ）和肝组织病理学进行了对比研究。结果：术前ＯＧＴＴ曲地Ｐ型者切肝后恢复顺利；Ｌ型者对肝切的耐受性差，术后易发生肝功能衰竭等并发症，其肝硬化和蔼多为ＣⅢ或ＣⅣ级，曲线形态界于Ｐ和Ｌ型之间的Ｉ型患者２９例用肝门区域血管阻断法切肝，并在阻断血管前使用预     

L-丙酰肉碱对再灌注心肌损伤的保护及体外抗自由基作用

目的:观察L－丙酰肉碱对缺血再灌注心肌的保护作用，并探讨其机理。方法：采用大鼠在体心脏冠状动脉前降支阻断5min造成缺血再灌注模型，持续心电监护，观察心律失常与心功能指标；应用电子顺磁共振观察L－丙酰肉碱对Fenton体系及二甲基亚砜（DMSO）碱性有氧体系产生自由基的作用。结果：L－丙酰肉碱静脉给药明显减少再灌注时室性心动过速、室性纤维颤动的发生（P＜0．05），促进再灌注后左室收缩压、左室压最大上升速率、左室压最大下降速率、心力环面积的恢复，与对照组相比，各参数均明显增高（P＜0．05）；静脉注射L－丙酰肉碱100mmol／L时促进Fenton体系OH的产生，而500mmol／L时产生明显抑制作用，L－丙酰肉碱明显抑制DMSO碱性有氧体系OS的产生。结论：L－丙酰肉碱明显减少再灌注心律失常的发生，促进再灌注后心功能的恢复。推测它对自由基的作用可能是再灌注损伤保护机理之一。     

中国女性的生殖健康权力

<正> 中国的计划生育工作和人口控制的进程取得了举世瞩目的成就,中国妇女在这方面做出了巨大的贡献。在目前的生育调节工作中,妇女承担了几乎全部的生育调节和养育子女的责任及义务。社会、家庭甚至妇女本身都默认和接受了这种程式化的规范。

Exercise in the prevention and treatment of chronic disorders

The Defense Women's Health Research Initiative commissioned a review of the literature of women's health issues. This was performed and published by the Institute of Medicine. In this publication it was noted that health promotion and disease prevention in women should be an area of high priority for military medicine. This article details some of the ways in which exercise may make substantial contributions to this goal.

The available evidence indicates that there is an inverse association between physical activity and a variety of chronic diseases. Moreover, physical activity appears to influence psychological well-being. Aerobic exercise is the mode most frequently studied, and appears to confer positive changes, but other forms of exercise may prove to be equally beneficial. However, the appropriate duration, intensity, and frequency of the exercise have not been determined for any of these chronic health problems and must be considered before global recommendations can be offered. Efforts to promote physical activity within the community, schools, and homes must be initiated to achieve the goals set forth in Healthy People 2000, so the health of our women can improve. Future studies will be required to identify mechanisms whereby physical activity confers benefit.     

透明质酸钠玻璃体腔内充填在严重开放性眼球损伤治疗中的应用

目的 研究透明质酸钠玻璃体腔内充填对严重开放性眼球损伤预后的影响。方法 在严重开放性眼球损伤一期手术缝合后玻璃体腔内充填透明质酸钠至眼压Tn。结果 用透明质酸钠在玻璃体腔内充填，眼球萎缩的发生率（6．67％）明显低于用BSS液充填的发生率（70．58％）。结论 透明质酸钠玻璃体腔内充填在严重开放性眼球损伤治疗中的应用对眼球外形维持和视功能恢复有重要作用。     

Detection of cell apoptosis by MTT assay.]

OBJECTIVE: To study the feasibility of using MTT assay to detect cell apoptosis. METHODS: K562 cells were grown in RPMI 1640 medium supplemented with 10% calf serum and 4 micromol/L arsenic trioxide. Apoptosis was induced in the cultured cells by As2O3, and the cells were detected with optical microscope, DNA gel electrophoresis and MTT staining respectively. RESULT: MTT staining could also accurately detect cell apoptosis, by which the apoptotic cells were easily distinguished from normal cells and dead cells. CONCLUSION: MTT staining is simple, convenient and practical for detecting cell apoptosis.
