表达谱基因芯片筛选体外循环前后心肌细胞因子的变化

Objestive Systemic inflarmmation may be triggered by injury, hypothermia, ischemia-reperfusion and the contact of the blood with foreign body during cardiopulmonary bypass (CPB). To determine the application values of gene chip technique in the clinical practice and the study of cardiovascular stagery, as well as to provide clues to the study of inflammatory responess during CPB, microarry for gene expression profiles was used to identify the differences in the gene expression of myocardium between pre-and post- CPB. Methods Six adult patients who underwent CPB from March to May in 2003 were involved. Samples of right atrium were col- lected before and at immediate end of CPB. BD AtlasTM cDNA Expression Arrays was used to identify the differences in the gene ex- pression of cytokines. The results were compared with that of semi-quantative RT-PCR. Resellts The mean age of 6 patients (5 males and 1 female) was (32.67± 11.72) years. The baseline heart function was gradeⅡin 3 cases and grade Ⅲ in 3 other cases. The baseline left ventricular ejection fraction(LVEF)was (58.17±7.91)%. The mere duration was (91.67±43.88) minutes for CPB and was (58.67±43.46) minutes for aorta blocking. The minimum nasopharynx/rectal temperture was (29.37±1.90)℃/ (32.15±1.52)℃. Gene expression profiles of cytokines in the myocardium pre- and post-CPB were analysed successfully. The ex- pression of IL-6, IFN-γ,Wnt5a, TNFRSF1B, a member of tumor necrosis factor receptor superfamily, PIGF and MFNG in the myo- cardium were unpregulated after CPB. Conclusion Microarray technique is applicable in the study of cytokines changes dying CPB. cDNA microarray identified pleliminarily the differences in the gene expression between pre- and post-CPB. These genes may be in- valved in inflammation and other psthophysiological responses incuced by CPB. The myocardiym is probably one of the major sources of cytokines during CPB. Further study may be helpful in understanding the llngthe development of inflammation during CPB, and eventually, reducing the post-operative complications.

12例医源性腓总神经损伤的原因分析与护理

本文对12例医源性腓总神经损伤原因进行了分析，结合临床提出针对性的护理要点，现总结如下。     

CT导向肺穿刺活检对肺部占位病变的诊断意义

肺部占位病变应用常规X线检查，辅以CT或MRI等检查方法，多数可作出临床诊断，有些病例需作CT引导下穿刺活检方能明确诊断。我们自1999年9月～2005年12月对36例不能明确性质的肺部占位病变进行了CT引导经皮穿刺活检，均获得满意结果，方法简便、效果可靠。     

重视有机磷农药中毒的出院指导

有机磷农药中毒的病人一般在临床症状、体征消失，停药观察2-3天、重者观察3—7天，全血胆碱酯酶获得70％以上，精神及饮食获得正常者方可出院。出院时的护理相当重要，因患者在恢复期对有机磷的敏感性增高，只要再次少量接触有机磷即可中毒闭。因此，我们需根据具体情况给予正确指导。     

宫颈妊娠1例临床治疗分析

1病例 患者，女，27岁。孕3产1。因“停经50＊天，阴道不规则流血2周”于2005年8月26日入院。该患平素月经规律，末次月经为2005年7月7日，于8月21日无明显诱因出现阴道流血，量时多时少，有血块，无腹痛。既往史：该患于2年前曾剖宫产1次。人院查体：T：36．8℃、BP：100／70mmHg。头、颈、心、肺未见明显异常。腹平软，无压痛及反跳痛，无肌紧张。妇科检查：外阴发育正常，阴道通畅，阴道内有少许暗红色血液，元异味，宫颈表面光滑，略增粗，宫口微开，可见少许暗红色凝血块堵塞宫口，举摆痛（＋），前穹窿饱满，触痛明显，子宫后位，正常大小，质略软，无压痛，活动度良好；双附件未见异常。

羊水栓塞的高危因素及临床特点

目的：探讨羊水栓塞的高危因素及临床特点。方法：回顾性分析我院1995年～2005年收治的3例足月待产引起的羊水栓塞的发病诱因、临床特点及治疗方法。结果：羊水栓塞占同期足月住院分娩的1／10000，3例均有明显的诱因，即羊膜腔内压力过高、血窦开放、胎膜破裂，2例发病急，病情危险，最后导致死亡，1例发病虽急，但经过及时有效的治疗痊愈。结论：羊水栓塞根据发病的诱因，典型的症状体征，辅助检查常可正确诊断，一旦确诊，应立即抢救产妇，主要原则是：改善低氧血症；抗过敏、抗休克、防治DIC和肾功能衰竭，预防感染。
