艾滋病已成为一个既现实又棘手的社会问题.现实在于它不仅造成了国家在经济上的沉重负担,同时在社会伦理上也给国家带来很大的负面影响;棘手的是对于艾滋病感染者或艾滋病人,我们不但要加强对他们控制的情况下给予他们关爱,还要维护他们的生存权、工作权和婚姻权.     

后囊连续环形撕囊在儿童人工晶体植入术的应用

后发障是儿童白内障最常见的并发症，是导致术后视力下降的主要原因，故降低后发障的发生率对提高术后视力及减少弱视的发生非常重要，以往文献报道大多是术后行ND-YAG激光后囊切开术来治疗后发障。笔者近年对儿童白内障采用白内障摘除人工晶体植入联合后囊连续环形撕囊术预防人工晶体术后后囊混浊，效果肯定，报告如下。

心脾综合征的多普勒超声心动图诊断

目的:探讨多普勒超声心动图对心脾综合征的诊断价值,分析其心脏伴随畸形漏诊及误诊原因,提高对心脾综合征诊断的准确率。方法:本文总结了221例心脾综合征患儿的超声检测结果,并与其心血管造影或磁共振检查结果进行对照。结果:超声心动图诊断为心脾综合征与心导管或磁共振结论符合者199例(占90.0%),诊断不符合者22例(占10.0%)。结论:多普勒超声心动图可以较准确地诊断心脾综合征,但对其心脏伴随畸形检出的准确率尚待进一步提高。     

第一产程胎心监护异常226例的相关因素分析

目的探讨第一产程胎心监护异常的相关因素，提示处理措施。方法2004年1月1日。12月31日对我院226例第一产程胎心监护异常的相关因素进行回顾性分析。结果第一产程胎心监护异常为综合因素所致，胎儿高危因素为91.59％，母体高危因素为65．49％，产程处理因素为42．92％。结论第一产程胎心监护异常主要与胎儿因素、母体因素有关，提高产前检查质量、加强产程监护、正确选择分娩方式极为重要。     

Pain levels experienced with activities after cardiac surgery.

BACKGROUND: Acute pain is common after cardiac surgery and can keep patients from participating in activities that prevent postoperative complications. Accurate assessment and understanding of pain are vital for providing satisfactory pain control and optimizing recovery. OBJECTIVES: To describe pain levels for 5 activities expected of patients after cardiac surgery on postoperative days 1 to 6 and changes in pain levels after chest tube removal and extubation. METHODS: Adults who underwent cardiac surgery were asked to rate the pain associated with various types of activities on postoperative days 1 to 6. Pain levels were compared by postoperative day, activity, and type of cardiac surgery. Pain scores before and after chest tube removal and extubation also were analyzed. RESULTS: Pain scores were higher on earlier postoperative days. The order of overall pain scores among activities (P < .01) from highest to lowest was coughing, moving or turning in bed, getting up, deep breathing or using the incentive spirometer, and resting. Changes in pain reported with coughing (P = .03) and deep breathing or using the incentive spirometer (P = .005) differed significantly over time between surgery groups. After chest tubes were discontinued, patients had lower pain levels at rest (P = .01), with coughing (P = .05), and when getting up (P = .03). CONCLUSIONS: Pain relief is an important outcome of care. A comprehensive, individualized assessment of pain that incorporates activity levels is necessary to promote satisfactory management of pain.

血管紧张素转换酶2与糖尿病肾病

The identification of angiotensin-converting enzyme (ACE)2 opened new recognition of renin-angiotensin system (RAS). ACE2 degrades Ang Ⅱ to Ang (1-7), maintains homeostasis of RAS with ACE. Studies have revealed that ACE2 has important functions in diabetic nephropathy. It may be a target for drug and is used as gene therapy for diabetic nephropathy. Amplifying ACE2 activity may have a potential therapeutic role for diabetic nephropathy.     

盲肠结扎穿刺致豚鼠急性肺损伤动物模型建立

目的 研究败血性急性肺损伤的动物模型，并探讨其在急性肺损伤研究中的意义。方法 用盲肠结扎穿刺(CLP)法的豚鼠急性肺损伤模型，结合动脉血气分析、外周血白细胞计数、肺湿重／干重比值(W／D)及肺组织病理观察。结果 CLP模型中动物的症状和表现缓慢出现，逐渐恶化．最后导致败血性休克，于2d左右出现大量死亡。结论 用盲肠结扎穿刺的方法制作豚鼠急性肺损伤动物模型较大鼠内毒素性休克，表现更类似于人类的肠源性肺损伤，且症状缓慢发生，逐渐恶化，有利于观察和进行各种干预。
