超声检查胰腺血供变化在诊断急性胰腺炎中的价值

急性胰腺炎（AP）的二维超声诊断价值已经被临床认可。近年来，有学者对肿块型胰腺炎的彩色多谱勒进行了研究，发现彩色多谱勒超声对肿块型胰腺炎有诊断价值。本研究在于探讨彩色多谱勒超声、彩色能量超声在诊断AP中的价值和意义。     

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.     

急性有机磷中毒患者动态心电图及心肌酶谱监测的临床意义

1998～2003年，我们对收治的96例急性有机磷中毒(AOPP)患者(观察组)进行动态心电图(DCG)及心肌酶谱监测，并与30例正常人对照(对照组)，旨在为其救治提供依据。     

总胆汁酸联合肝脏酶谱测定在肝脏疾病中的鉴别意义

目的探讨总胆汁酸联合肝脏酶谱测定在肝脏疾病中的鉴别意义.方法用日立7080全自动生化分析仪分析304例病人血清中总胆汁酸与肝脏酶谱含量进行统计,取均数和阳性率.结果急性肝炎时TBA、ALT、AST、r-GT阳性率都很高.而慢性肝炎时.TBA、r-GT阳性率较高,其它项目基本正常,肝硬化时,TBA也明显升高,且AST、r-GT都高于ALT、CHE、AKP,肝癌时TBA、ALT、AST、AKP、r-GT、CHE阳性率都根高.胆石症时TBA明显升高且在阻塞的不同阶段几乎保持不变.结论总胆汁酸联合肝脏酶谱检测对急性肝、慢性肝炎、肝硬化、肝癌、胆石症鉴别具有一定的参考价值.     

头孢菌素的二硫醒样副作用

<正>近年来,随着各种药物的广泛应用,药物的不良反应也日渐增多。头孢菌素类的抗菌素,因抗菌谱广、耐酸、耐酶,毒性小、副作用少,临床运用很广泛。本文对2001年9月-2005年9月我院遇到应用头孢菌素类药(主
