试论手法之补泻及其辨证应用

本文通过古代文献论述以及现代研究,提出了手法补泻的方向、缓急、轻重、时间、手法和受力部位和特性的六个影响因素,并以以"三因制宜"为纲,从因地、因时、因人的年龄、性别、体质、所患疾病、病情变化、脏腑功能、耐推拿程度以及心量状况的不同等十个方面论述手法之补泻的临床辨证施用.     

情绪性疾病知多少

我们知道，人感染了细菌、病毒会得病，机体受了创伤会发病，饮食不当也会患病，却往往忽视了另一种非常常见，却又不足以引起人们注意的致病因素，这就是不正常的情绪变化，它可能导致很多疾病发生，下面这些疾病皆可由不良的情绪所致。     

优化商品陈列 刷新销售业绩

研究表明：商品陈列面的大小变化、化妆品陈列的高低变化和化妆品的陈列时间等均会影响化妆品店的销售额。首先，商品陈列面的大小变化会引起销售额的变化。如由4个货位减少到2个货位，销售额锐减48％；由3个货位减少到1个货位，销售额锐减68％；由2个货位增加到4个货位，销售额增加40％。所以，在化妆品店的商品陈列中，要加大购买频率较高品种的陈列面，并以大陈列面形成聚焦点，刺激顾客购买。     

血透患者中枸橼酸西地那非的药代动力学及血流动力学变化

患有肾病的男性中ED发病率很高。枸橼酸西地那非是勃起功能障碍的高效治疗药物，严重肾功能不全会使该药清除率下降，但在血透治疗的终末期肾病患者中，该药的药代动力学和血液动力学研究尚未见报导。为了研究血透患者中，该药的药代动力学和血流动力学变化，Grossman EB等人让15例慢性门诊血透维持患者在血透前2h及血透后2h口服单剂西地那非，先服哪一次进行随机分配确定。     

Changes in T .lymphocyte subsets after severe traumatic brain inJury

BACKGROUND： Besides local changes of cranial parenchymal cells, hemorrhage, etc., severe traumatic brain injuries also cause the changes of total body fluid and various functions, and the changes of lymphocytes and T lymphocyte subsets should be paid more attention to. OBJECTIVE： To reveal the changing laws of T lymphocyte subsets after severe traumatic brain injury, and compare with mild to moderate brain injury. DESIGN： A comparative observation. SETTINGS： Department of Neurosurgery, Longgang District Buji People＇s Hospital of Shenzhen City; Central Laboratory of Shenzhen Hospital of Prevention and Cure for Chronic Disease. PARTICIPANTS： All the subjects were selected from the Department of Neurosurgery, Longgang District Buji People＇s Hospital of Shenzhen City from August 2002 to August 2005. Thirty patients with severe brain injury, whose Glasgow coma score （GCS） was ≤ 8 points, were taken as the experimental group, including 21 males and 9 females, aging 16 - 62 years. Meanwhile, 30 patients with mild traumatic brain injury were taken as the control group （GCS ranged 14- 15 points）, including 18 males and 12 females, aging 15 -58 years. All the subjects were in admission at 6 hours after injury, without disease of major organs before injury Informed consents were obtained from all the patients or their relatives. METHODS： （1） The T lymphocytes and the subsets in peripheral blood were detected with immunofluorescent tricolor flow cytometry at l, 3, 7 and 14 days after injury in both groups. （2） The conditions of pulmonary infections were observed at 4 days after injury. The differences of measurement data were compared with the t test. MAIN OUTCOME MEASURES： Changes of T lymphocytes subsets at 1 - 14 days after severe and mild or moderate traumatic injury. RESULTS： Finally, 28 and 25 patients with mild to moderate traumatic brain injury, whereas 25 and 21 patients with severe traumatic brain injury were analyzed at 7 and 14 days respectively, and the missed ones died due to the development of disease. （1） Changes of T lymphocyte subsets： At 1 and 3 days after injury, CD3, CD4, CD8, CD4/CD8 began to decrease, whereas CD8 increased in the experimental group, which were very significantly different from those in the control group （t =2.77 - 3.26, P 〈 0.01）, and began to recover at 7 days, which were significantly different from those in the control group （t = 2.06 - 2.24, P 〈 0.05）, and generally recovered to the normal levels at 14 days （P 〉 0.05）. （2） Conditions of pulmonary infections： At 4 days after injury, the rate of pulmonary infection was significantly different between the experimental group and control group [73% （22/30）, 0, x2=37.29, P 〈 0.01]. CONCLUSION： Patients with severe traumatic brain injury suffer from damages of cellular immune function at early period （within 7 days）, and they are easily to be accompanied by pulmonary infections.

40例老年急性肾功能衰竭的临床分析

由于老年人肾脏的解剖生理变化导致应变能力的相应下降，易发生急性肾功能衰竭（ARF）。我院自2000年开展血液透析治疗以来，提高了对老年ARF的治愈好转率。笔者收集院1998年1月～2005年1月老年ARF病例40例进行临床分析，报道如下：
