急性心肌梗死心肺复苏后静脉溶栓的疗效观察

急性心肌梗死(AMI)溶栓治疗可使闭塞的冠状动脉再通,挽救濒临坏死的心肌,使坏死范围缩小,改善预后,但对于心肺复苏的患者来说,溶栓是否会增加并发症及病死率,是临床医生一直关心的问题,本组对经过心肺复苏的急性心肌梗死与单纯急性心肌梗死患者溶栓疗效进行回顾性分析,现报告如下.     

7,8-氧化苯乙烯对小鼠SOD活性及MDA含量的影响

选取昆明种小鼠40只,雌雄各半,随机分成7,8-氧化苯乙烯(SO)低(125 mg/kg)、中(250 mg/kg)、高(500 mg/kg)3个剂量组和对照组。空腹灌胃染毒,24 h后测定血液、肝脏、脑、肾脏组织的丙二醛(MDA)含量及超氧化物歧化酶(SOD)活性。SO中、高剂量染毒组小鼠肝脏SOD活性下降,与对照组比较差异有统计学意义(P0.05),各剂量染毒组脑组织SOD活性增高,MDA含量下降,与对照组比较差异有统计学意义(P0.05,P0.01);提示7,8-氧化苯乙烯可致脑和肝组织的氧化损伤。     

痛风局限性骨破坏误诊为骨肿瘤5例分析

[目的]分析痛风局限性骨破坏误诊原因;探讨表现为单纯局限性骨破坏的痛风的诊断、治疗方法和临床效果。[方法]回顾性分析2010年1月~2016年12月,本科收治痛风局限性骨破坏患者的临床资料,共5例,全部为男性,平均年龄(26.53±4.64)(19~32)岁。术前经局部X线片、CT或MRI检查。病变位于距骨1例、髌骨2例、趾骨2例。该5例患者入院初步诊断为良性肿瘤,5例采用刮除植骨术治疗,术后病理诊断为痛风,采用抗痛风药物治疗,术后随访以及X线片检查判断疗效。[结果]5例患者经手术治疗,组织病理学确诊为痛风,病理确诊率100%。术后辅以抗痛风药物治疗,经6~36个月,平均(24.12±3.78)个月的随访,未见复发。[结论]局限性骨破坏,需鉴别骨肿瘤与痛风;实验室检查尿酸结果升高的患者,应高度怀疑痛风引起;痛风局限性骨破坏采用病灶刮除植骨,是一种有效的治疗方法。     

左半结肠癌急性梗阻一期切除吻合41例

希氏束旁起搏治疗缓慢型心律失常

起搏器已经成为缓慢型心律失常有效的治疗方法.我国每年约有几万名患者需要植入人工心脏起搏器治疗,以往单腔或双腔起搏器心室电极植入右室心尖部,它改变了正常的心室激动顺序,使左、右心室激动不同步,从而对血流动力学和心功能产生不良影响,易出现起搏器综合征、心脏扩大,增加房颤、心衰的风险,增加病死率[1].我们尝试希氏束旁起搏治疗缓慢型心律失常,观察2年,收到了良好的效果.     

腹腔动脉CT血管成像固定毫安秒低剂量技术探讨

Objective To characterize the feasibility of low-dose CT angingraphy on 16-slice multislice computed tomography (16-MSCT), and its relationship to the noise in the pre-contrast image and enhancement value.Methods Forty-three consecutive patients (male 21, female 22, mean age 59 years, median age 56 years) underwent abdominal 16-MSCT (Toshiba Aquilion 16) with constant scanning parameters including 120 kVp, a 0.5-second gantry rotation time, a pitch of 0.938: 1, and 16×1-mm detector collimation.The mA was set at 200 in the pre-contrast scan and 160 in the contrast-enhanced scan.The arterial phase images were retrospectively reconstructed with 1-mm slice thickness, 0.8 mm interval.The pre-contrast noise was defined as the standard deviation (SD) of the aorta at the level of right posterior crura of diaphragm.The enhancement of aorta was also measured at level of celiac artery.The volume rendering of CT angiography was made and classified into three grades (excellent, good, bad).Receiver operating characteristic curve (ROC) was used to evaluate the relationship between the image quality of CT angiography and noise in the pre-contrast image and enhancement value.Results Twenty-five cases had the aorta enhancement between 300.0--400.0 HU.The sensitivity and specificity of excellent CTA image was 75% and 62%, respectively when the SD was 12.00.Eighteen cases had the aorta enhancement more than 400.0 HU.The sensitivity and specificity of excellent CTA image was all 100% when the SD was 12.25, and 100% and 75%, respectively when the SD was 13.35.The area under curve of CTA image quality and enhancement in receiver-operated characteristic analysis was O.907.The enhancement was more than 356.7 HU when the sensitivity and specificity of excellent CTA image was 100% and 60%, respectively, and 389.8 HU when 78% and 80%.When the enhancement was more than 442.4 HU, the specificity of excellent CTA image was 100%.Conclusions MSCT angiography with low radiation dose is feasible.Good CT angiography demands great enhancement, and then, the needed mAs is lower when the SD is smaller.
