不同给药途径的腺苷预处理对大鼠缺血再灌注心肌的保护

Objective To evaluate the effect on myocardial protection of adenosine preconditioning in different route of administration through right jugular vein and left ventricle.Methods 48 SD rats were randomly divided into ischemia reperfusion group(blank control),ischemic preconditioning group(IP,positive control),adenosine venous infusion group,adenosine in ventricular group,normal saline(NS)venous infusion group(negative control I)and NS in ventricular group(negative control Ⅱ).The ischemia reperfusion rats model were established in vivo,and then changes of heart function,serum cardiac troponin T (cTnT),superoxide dismutase(SOD),malondialdehyde(MDA)and expression of nuclear factor KB(NF-kB) were observed.Results SOD in IP[(208.63±23.88)U/ml],adenosine venous infusion group [(178.27±11.56) U/ml]and adenosine in ventricular group[(191.31±28.14)U/ml]were significantly higher than that in the ischemia reperfusion group[(145.05±23.18)U/ml](P<0.05),cTnT,MDA and expression of NF-kB were lower than that in the ischemia reperfusion group (P<0.05).Heart function was significantly better than that in the ischemia reperfusion group(P<0.05);SOD in adenosine in ventricular group was significantly higher than that in adenosine venous infusion group(P<0.05).cTnT,MDA and expression of NF-kB were lower than that in adenosine venous infusion group (P<0.05).Conclusion Adenosine preconditioning may mimic protective effect of ischemic preconditioning. The effect on myocardial protection of adenosine in ventricular group was better than that of adenosine venous infusion group.

中枢性疾病在耳科的临床表现

耳与颅脑紧邻 ,不少颅脑疾病可以引起相应的耳科表现 ,如不能及时确诊 ,容易造成误诊。现将我科诊治的 7例此种中枢性疾病报告如下。1　病例报告7例的临床资料见表 1。 7例的听力学检查见表 2。2　讨论耳与颅脑紧邻 ,血管供应密切相关 ,不少颅脑疾病可以扩展、累及耳部 ;或直接侵犯有关的脑神经核、神经根及神经的颅内段 ,引起相应的耳科症状和体征 ,如耳鸣、耳聋、眩晕、视物旋转、面痛、面瘫、面肌阵挛及行走不稳等。耳科医师仔细分析这些临床表现有助于颅脑疾病的早期诊断。本文 7例均曾到耳科多次就医但均未确诊。其误诊原因 ,一是临床…     

肾综合征出血热患者异型淋巴细胞与肾功能、血小板的相关性

肾综合征出血热 (hemorrhagicfeverwithrenalsyndrome,HFRS)是由汉坦病毒引起的自然疫源性传染病 ,以急性起病、发热、出血、低血压和肾脏损害为特征[1] ,是临床较常见的传染病之一 ,也是战时更易于流行传播的疾病 ,所以对其病理指标的研究 ,不但对临床诊治有一定帮助 ,而且在军事医学上也有一定意义。关于肾综合征出血热患者的各病期血液学分析已有报道 ,而对HFRS患者血中异型淋巴细胞 (异淋 )、血小板、肾功能的相关性分析未见报道。本文对 4 0例HFRS患者血中的异淋与肾功能、血小板的相关性进行了分析 ,现报告如下。1　材料与方法1 …     

中医辨治经断前后诸症

绝经标志妇女月经的终结,发生在所有妇女,究竟是正常过程还是一种疾病尚有争论.然而伴随绝经的发生,部分妇女出现异常心理和躯体的各种改变,如月经紊乱,烘然汗出,烦躁易怒,五心烦热,面浮肿胀,阴道干涩而痛,甚则心脑血管疾病的发生及骨质疏松症.这些症状轻重不一,参差出现,短者数月,长者迁延数年或数十年,严重困扰妇女的身心健康,影响妇女正常工作和生活质量.
