严重脊柱侧凸矫形患者围术期的舒适护理

对28例严重脊柱侧凸患者行矫形手术，结果手术均获成功，松解术后1周行后路矫形内固定加植骨融合术，术后Cobb角平均为40．8°，侧弯矫正率平均为52．0％。术后随访6～30个月，均无并发症发生。提出在做好脊柱侧凸矫形手术常规护理的同时，加强患者心理、体位、呼吸、镇痛、排便等方面的舒适护理，可增强患者舒适感，为手术获得成功和患者顺利康复提供有力保障。     

Lithium and haloperidol differentially alter the dynorphin A (1-8) and enkephalin levels in the neurointermediate lobe of rat pituitary

Repeated administration of the antimanic drug lithium (4 mEq/kg/day for 2, 4 or 6 days, i.p.) to rats produced a progressive decline and eventual depletion of dynorphin-A (1-8) (DYN) concentration whereas Met5-enkephalin (ENK) was only marginally decreased in the neurointermediate lobe of the pituitary (NIL). Administration of a neuroleptic haloperidol neither affected ENK and DYN levels nor influenced lithium-induced changes. The study reveals that lithium produces a preferential perturbation in the dynorphin system relative to the enkephalin system. These results taken together with other evidence, indicate that dynorphin is possibly coreleased with vasopressin following lithium administration and provide a pharmacological support to the previously described colocalization and corelease of these endogenous peptides in the NIL.

喘息是儿童时期常见的症状之一,支气管扩张药物在年幼儿童中使用的有效性是多年来颇有争议的一个临床问题。争论的焦点在于,以往认为婴儿支气管平滑肌发育不成熟,喘息时气道动态闭合度增高和相对显著的黏膜水肿使其对支气管扩张剂的反应较弱。而近年的研究显示,虽然婴幼儿对支气管扩张剂的治疗反应弱于年长儿童和成年人,但在婴儿时期气道就存在对支气管扩张剂的反应[1],合理使用支气管扩张剂有利于改善喘息儿童的临床症状。1临床常用的支气管扩张剂1.1β2肾上腺素受体激动剂选择性β2受体激动剂是强效支气管扩张剂,支气管扩张作用是氨茶碱的…     

乳猪肝细胞的分离、培养及功能检测

目的 为构建生物人工肝进行肝细胞的准备。方法 采用胶原酶半原位灌流法分离单个乳猪肝细胞,并对其活力及单层和聚集培养后的白蛋白、尿素合成功能进行检测。结果 采用本方法从每头乳猪中分离到的单个肝细胞数为(3.1±1.5)×10~(10),活性超过95％。在加入激素和生长因子的培养基中单层培养时,肝细胞功能良好,可维持2周左右。而在未加入激素和生长因子的培养中肝细胞虽能存活1周,但功能于24h后即丧失。球形聚集培养可实现肝细胞的大量培养,且生物学活性较单层培养显著提高。结论 采用胶原酶半原位灌注法所得单个乳猪肝细胞基本能满足构建生物人工肝对肝细胞数量的要求。聚集培养接种密度大,细胞生物学活性高,可用于构建生物人工肝。     

经皮肾穿气压弹道碎石联合体外冲击波碎石治疗上尿路结石

目的 探讨提高上尿路结石碎石成功率的微创治疗方法。方法 采用经皮肾穿微造瘘输尿管镜气压弹道碎石，术中放置双J管，术后配合体外冲击波碎石术(ESWL)治疗上尿路结石48例。结果 结石总排净率为89．1％，结石最小排净率79．2％，无严重并发症发生。结论 该方法结石排净率高，创伤较小，手术并发症少，是上尿路结石较为理想的微创治疗方法。     

Nuclear Factor κB and Anesthetic Preconditioning during Myocardial Ischemia-Reperfusion

Background: Volatile anesthetic preconditioning (APC) protects against myocardial ischemia-reperfusion (IR) injury, but the precise mechanisms underlying this phenomenon remain undefined. To investigate the molecular mechanism of APC in myocardial protection, the activation of nuclear factor (NF) [kappa]B and its regulated inflammatory mediators expression were examined in the current study.

Methods: Hearts from male rats were isolated, Langendorff perfused, and randomly assigned to one of three groups: (1) the control group: hearts were continuously perfused for 130 min; (2) the IR group: 30 min of equilibration, 15 min of baseline, 25 min of ischemia, 60 min of reperfusion; and (3) the APC + IR group: 30 min of equilibration, 10 min of sevoflurane exposure and a 5-min washout, 25 min of global ischemia, 60 min of reperfusion. Tissue samples were acquired at the end of reperfusion. NF-[kappa]B activity was determined by electrophoretic mobility shift assay. The NF-[kappa]B inhibitor, I[kappa]B-[alpha], was determined by Western blot analysis. Myocardial inflammatory mediators, including tumor necrosis factor [alpha], interleukin 1, intercellular adhesion molecule 1, and inducible nitric oxide synthase, were also assessed by Western blot analysis.

Results: Nuclear factor [kappa]B-DNA binding activity was significantly increased at the end of reperfusion in rat myocardium, and cytosolic I[kappa]B-[alpha] was decreased. Supershift assay revealed the involvement of NF-[kappa]B p65 and p50 subunits. APC with sevoflurane attenuated NF-[kappa]B activation and reduced the expression of tumor necrosis factor [alpha], interleukin 1, intercellular adhesion molecule 1, and inducible nitric oxide synthase. APC also reduced infarct size and creatine kinase release and improved myocardial left ventricular developed pressure during IR.     

理性看待高密度脂蛋白

由于新药toreetrapib的临床研究未获预期结果 ,以及残存心血管危险性这一概念的提出,近年人们再次对高密度脂蛋白(HDL)及高密度脂蛋白-胆固醇(HDL-C)给予高度关注.研究提示,在关注HDL-C水平的同时,不能忽视HDL的功能状态.目前最有效和安全的升高HDL-C水平的方法 还是生活方式调节,主要包括锻炼、减轻体重和戒烟等.
