The CoWP film with good magnetic performance and corrosion resistance was electrolessly plated from alkaline solution. The technical parameters of the electroless plating system were optimized. When the pH value of electroless plating solution was 11.0 and the reducing agent (NaH2PO2) content was 0.4 mol L 1, the target chemical reactions proceeded in the electroless plating solution smoothly with negligible interference and side effects. CoWP film prepared under optimal deposition condition contained more hexagonal close-packed (hcp) cobalt (ε-Co) of [110] and crystallographic orientation of Co [002]. VSM analysis reveals that the saturation magnetization of the CoWP film is 100～220 Am2 kg 1 and coercivity is (2.87～4.38)×104 A·cm 1. The corrosion behavior of CoWP film in 3.5% NaCl aqueous solution was studied by electrochemical experiments. The results prove that the corrosion resistance of the CoWP film deposited under the optimal depo-sition condition exhibites relatively lower corrosion current of (3.054～3.162)×10 6 A·cm 2. The surface morphology analysis indicates that the film is smooth and composed of regular-shaped crystallites.

目的:探讨运动性心肌肥大大鼠背根神经节降钙素基因相关肽基因表达的变化。方法:雄性SD大鼠随机分为对照组(n=33)和耐力训练组(n=33)。耐力训练组进行10周的跑台耐力训练,建立运动性心肌肥大模型。建模后48h,从两组随机抽取17只大鼠,连续3天进行力竭运动,最后一次力竭运动后即刻处死全部实验动物。记录力竭运动距离和大鼠体重,取大鼠心脏和腰段背根神经节,记录心脏湿重,采用荧光定量聚合酶链式反应技术测定大鼠背根神经节降钙素基因相关肽mRNA的表达量。结果:10周后,耐力训练组大鼠心脏重量与体重之比和力竭运动距离显著高于对照组(P<0.01)。与对照组比较,力竭运动前耐力训练组背根神经节CGRPmRNA表达显著下降(P<0.01),力竭运动后耐力训练组背根神经节CGRPmRNA表达与力竭运动前相比无明显变化,而对照组较力竭运动前显著下降(P<0.01)。结论:运动性心肌肥大大鼠背根神经节CGRP基因表达下调,力竭运动后表达保持稳定。

本文报道全科医生接诊一例发热伴皮疹患儿时,从全科医学视角出发,采用约翰·莫塔教授的临床安全策略——临床5问思维法:(1)哪些常见疾病会引起发热伴皮疹?(2)哪些重要疾病不能忽视?(3)是否有潜在的常被掩盖的疾病?(4)有哪些容易被遗漏的病因?(5)家属是不是有什么话还没有说?结合病史、查体和辅助检查综合分析,确诊川崎病。本案例的启示:(1)发热伴淋巴结肿大,血常规提示细菌性感染,应用抗生素后效果欠佳,要考虑到川崎病的可能;(2)小儿发热性疾病,如果是用药后出现皮疹,不能简单归结为药物过敏,也要警惕川崎病;(3)眼结膜充血、口唇干红、口腔黏膜充血、杨梅舌等川崎病面容与急性热病容有些相似,在询问病史及查体时注意甄别。同时给予患儿家属心理疏导,体现以人为中心和以家庭为单位的全科医学理念。
