怎样让宝宝练习爬

问：我儿子9个月了。别人的宝宝已会爬了，可他不会。每次教他爬时，他都不配合。我该怎么办呢？     

PROTECTIVE EFFECTS OF ERYTHROPOIETIN ON MYO- CARDIUM AGAINST ISCHEMIA-REPERFUSION INJURY

Objective To explore the protective effects of erythropoietin （EPO） on myocardium against ischemia-reperfusion injury （ IRI）. Methods The Langendorff model of isolated rat heart was set up and a 3-stage protocol was performed： 20 min stabilization, 30 min global ischemia, and 120 min reperfusion. Sixty SD rats were randomly divided into sham group, ischemia-reperfusion group （I/R group ） and EPO treated group （ EPO group）. Heart rate （ HR）, left ventricular developed pressure （ LVDP）, the first derivative （ △dp/dt max） and coronary flow （CF） were recorded at the 20th minute of stabilization and the 120th minute of reperfusion. Lactate dehydrogenase （LDH） and creatine phosphokinase （CK） in the coronary effluent at the 60th minute of reperfusion , the levels of myocardial nuclear factor-kappa B （NF-KB） and the myocardial content of tumor necrosis factor-α （TNF-α） ,interleukin-lβ （1L-lβ） were measured at the end of reperfusion. Results No statistically significant differences were observed on the aspect of hemodynamic parameters among the groups at the 20th minute of stabilization, but at the 120th minute of reperfusion, the recovery ratio of EPO group was higher than I/R group （P 〈0. 05）. LDH and CK in the coronary effluent, the levels of myocardial NF-KB and TNF-α,IL-lβ expression in EPO group were significantly lower than those in I/ R group, but higher than sham group （ P 〈 0. 05 ）. Conclusion EPO has protective effects on myocardium against 1RI possibly through the mechanism of relieving the myocardial inflanmtatory reaction by regulating the activation of NF-KB and then decreasing the expression of proinflammatory factors TNF-α and IL-lβ.     

七氟醚麻醉对患儿发育期大脑的损伤及脑保护的研究进展

因为婴儿发育尚未成熟,小儿麻醉一直是麻醉科的重点研究对象.在小儿麻醉中,七氟醚是常用的麻醉药物之一,该麻醉药物具有多重优势,比如麻醉效果显现迅速,患儿苏醒快,对患儿气道刺激较小,但是对患儿大脑会产生损伤.鉴于此,本文将对七氟醚在小儿麻醉中对发育期大脑的损伤进行简要综述,并总结相关脑保护干预措施.     

医护人员预防院内感染结核病的保护措施初探

目的：预防和控制医护人员结核病的发病率及其传播。方法：通过1995年收治279例肺结核病的调查统计，针对医护人员罹患结核病与工作环境关系的分析，提出若干防护措施。结果：本院内医护人员罹患结核病的比例较高(15．4％)．占职工传染病的第二位．特别是在传染结核病的潜在的高危科室发病率较高。结论：统计资料表明．在结核传染的高危工作区能严格地执行个人防护措施和增强潜在感染的预防意识或观念．是控制医护人员结核病发病率及传播的重要环节。同时本还提出五项针对性阻断结核传染的预防措施。     

肝脏手术中血液保护措施应用的临床进展

肝叶切除手术是治疗肝脏占位性病变的一种重要方法。由于肝脏解剖结构的特殊性,手术过程中常面临大出血的危险,需大量输入红细胞、血浆等制品,使病人又面临大量输血等并发症的危险。因此在肝切除手术中采取综合措施进行血液保护,已成为临床手术麻醉中的热点问题。本文就各种血液保护措施在肝脏手术中的临床应用作简要综述。
