在深静脉血栓—肺栓塞病程中腔静脉滤器的应用价值分析

目的：探讨腔静脉滤器(Vena cava filter VCF)在深静脉血栓(Deep venous thrombosis DVT)—肺栓塞(Pulmonary embolism PE)病程中的应用价值。方法：结合本组25例高危深静脉血栓一肺栓塞患者，对其中24例置放5种构型的永久型或临时型下腔静脉滤器(IVCF)26枚的临床疗效、影响病程与预后因素及病生理改变，复习文献分析讨论。结果：DVT有可能脱落导致PE或致死性肺栓塞；置放IVCF可有效预防肺栓塞，早期进行溶栓治疗，改变预后。结论：严格按适应证植入IVCF，对DVT—PE的早期治疗和预防致死性肺栓塞有重要意义，但其应用价值需进行综合评价和进一步探讨。

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.     

Low HDL‐cholesterol is common in European Type 2 diabetic patients receiving treatment for dyslipidaemia: data from a pan‐European survey

Aims To measure the prevalence of low high‐density lipoprotein (HDL)‐cholesterol (men < 1.03 mmol/l; women < 1.29 mmol/l) in European Type 2 diabetic patients receiving treatment for dyslipidaemia. Methods The pan‐European Survey of HDL‐cholesterol measured lipids and other cardiovascular risk factors in 3866 patients with Type 2 diabetes and 4436 non‐diabetic patients undergoing treatment for dyslipidaemia in 11 European countries. Results Diabetic patients were more likely to be obese or hypertensive than non‐diabetic patients. Most patients received lifestyle interventions (87%) and/or a statin (89%); treatment patterns were similar between groups. Diabetic patients had [means (SD)] lower HDL‐cholesterol [1.22 (0.37) vs. 1.35 mmol/l (0.44) vs. non‐diabetic patients, P < 0.001] and higher triglycerides [2.32 (2.10) vs. 1.85 mmol/l (1.60), P < 0.001]. More diabetic vs. non‐diabetic patients had low HDL‐cholesterol (45% vs. 30%), high triglycerides (≥ 1.7 mmol/l; 57% vs. 42%) or both (32% vs. 19%). HDL‐cholesterol < 0.9 mmol/l was observed in 18% of diabetic and 12% of non‐diabetic subjects. Differences between diabetic and non‐diabetic groups were slightly greater for women. LDL‐ and total cholesterol were lower in the diabetic group [3.02 (1.05) vs. 3.30 mmol/l (1.14) and 5.12 (1.32) vs. 5.38 mmol/l (1.34), respectively, P < 0.001 for each]. Conclusions Low HDL‐cholesterol is common in diabetes: one in two diabetic women has low HDL‐cholesterol and one diabetic man in four has very low HDL‐cholesterol. Management strategies should include correction of low HDL‐cholesterol to optimize cardiovascular risk in diabetes.     

关于单结合胆红素水溶性的研究

目的:进一步研究单结合胆红素(MCB)的水难溶特性及其在病理性胆汁中参与胆红素沉淀和色素性结石形成的作用机制.方法:应用胆红素高效液相色谱分析技术,先从人胆汁中获得结合胆红素,再经分离、制备及纯化得到纯MCB.然后观察其水溶解度并与其它型胆红素比较.结果:在pH7.9,温度37℃接近生理的条件下,MCB的溶解度(558.25±5.96μm)仅为双结合胆红素(DCB)的1/7,比不结合胆红素(UCB)高约44倍并随pH值改变而呈曲线变化.pH7.9时最大;pH4.5时为0;而当pH>9时,反而低于呈离于状态的UCB.结论:MCB虽作为结合型胆红素在胆道生理条件下的不溶性明显高于UCB,但比DCB要低得多;而在胆道病理条件下,其水溶性不但远低于DCB,甚至还不如离子化的UCB,这可能是MCB参与胆红素沉淀及胆色素结石形成的理化基础.

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…
