实验性腹主动脉瘤瘤体外径与iNOS相关性分析及分期研究

Objective To construct new model of experimental abdominal aortic aneurysm (AAA) and detect the AAA outer diameter and the change of induce nitric oxide synthase(iNOS) in the abdominal aor-tic aneurysm in different period,and analysis the correlation between experimental AAA and iNOS.Methods During the operation of the experiment group,the vascular prosthesis of PTFE was implanted to the rabbit abdominal aorta to form an aneurysm,while sham operation was done in the control group.The tissue of ab-dominal aortic aneurysm was harvested in 1 d,7d,14d,and 28d after operation,respectively.The tissue bo-mogenate concentration of iNOS in the abdominal aortic aneurysm were detected by enzyme linked immu-nosorbent assay (ELISA).Results In experimental group,mean concentration of the tissue bomogenate concentration of iNOS in the abdominal aortic aneurysm in 1 d,7 d,14 d,28 d were (22.129 ±2.518)μ/mL,(27.337±5.321) μ/mL,(36.047±4.584)μ/mL,(44.756±1.799)μ/mL,respectively;In control group,that was (12.499±1.807)μ/mL.The concentration of iNOS in experimental group was significantly higher than that of control group (P < 0.01).The difference during the experimental group all had statisti-cal significance (P < 0.05).Conclusion It is possible that iNOS has some biological function during the formation and progression of the abdominal aortic aneurysm.     

SUCCESSFUL ENDOSCOPIC CLOSURES OF COLONIC PERFORATIONS REQUIRING ABDOMINAL DECOMPRESSION AFTER ENDOSCOPIC MUCOSAL RESECTION AND ENDOSCOPIC SUBMUCOSAL DISSECTION FOR EARLY COLON CANCER

Endoscopic submucosal dissection (ESD) for colorectal cancer is not widely accepted because of its technical difficulty and the risk of perforation. In addition, the risk of peritonitis cannot be completely eliminated even if a perforation is closed successfully. Reported here are two cases of early colon cancer in which the patients sustained iatrogenic perforations of the ascending colon during conventional endoscopic mucosal resection and of the sigmoid colon during ESD, respectively, requiring abdominal decompression with an 18 G Medicut needle. Both of these perforations were successfully treated by endoscopic clipping. In conclusion, conservative medical management may be possible in patients who have undergone successful closure of colonic perforations using endoscopic clipping. In order to perform immediate endoscopic closure, abdominal decompression has been useful to decrease patient discomfort and colonic lumen collapse. Now, CO₂ insufflation is being used effectively for the prevention of pneumoperitoneum.     

重症急性胰腺炎合并急性肾功能衰竭的临床特点及治疗体会

目的 分析重症急性胰腺炎(SAP)合并急性肾功能衰竭(ARF)的临床特点,并总结治疗体会.方法 ①回顾分析南京军区南京总医院近9年63例SAP合并ARF临床资料,用多元直线回归方法分析影响ARF发生率的相关因素;②63例病人均行肠内营养支持(62.4±20.6d)和连续性肾脏替代治疗(CRRT)(15.6±8.7 d),51例行机械通气(21.7±12.4 d),54例早期腹腔穿刺,34例置鼻胆管或经皮经肝胆囊穿刺引流,18例行腹膜后脓肿穿刺引流,50例手术治疗.结果 SAP合并ARF的死亡率为31.7%,发生率为10.6%,SIRS持续时间、病情严重程度、ARDS、MODS、腹腔间室综合征等是SAP合并ARF的重要影响因素.结论 SIRS持续时间、病情严重程度、ARDS、MODS、腹腔间室综合征等是SAP合并ARF的重要影响因素;早期液体复苏、CRRT、有效维护脏器功能和局部引流是治疗成功的重要环节.     

连续浅缝法修补膜周型室间隔缺损

目的探讨连续浅缝法修补单纯膜周型室间隔缺损(pVSD)法的效果。方法选取2002年1月至2004年10月我院收治的体重10kg以内(≤10kg)50例单纯膜周型室间隔缺损患者,均采用自体心包连续浅缝法修补。结果主动脉阻断时间32±21min(14-52min),体外循环时间56±35min(29-69min)。无°房室传导阻滞发生,9例发生右束支传导阻滞,2例结性心律。2例膜周偏流出道型VSD患者因前上缘残余分流分别为0.4cm和0.3cm,再次手术修补;1例后下缘残留细束样分流,直径0.15cm,随访6个月后自愈;10例膜周偏流出道型VSD患者剪开三尖瓣,8例垂直瓣环,2例平行瓣环;1例三尖瓣中度反流,随访无加重;5例轻度反流,4例轻微反流,随访均无加重;1例心包积液;1例再次进入手术室止血。结论连续浅缝法是修补单纯膜周型室间隔缺损的有效外科纠治方法。     

A randomized trial comparing two different approaches of pacemaker selection.

AIMS: DDD-pacemakers are favoured in patients with sick-sinus-syndrome or AV-block. However, AAI-pacemakers for sick-sinus-syndrome or VDD-pacemakers for AV-block may provide similar benefit with lower costs. The aim is to show that a tailored approach (TA) with arrhythmia-specific pacemaker selection was equal to a standard approach (SA) regarding quality of life (QoL) at lower costs. METHODS AND RESULTS: The study was prospective and randomized with QoL as primary endpoint. Secondary endpoints were a combined endpoint of all-cause mortality, worsening heart failure or angina, atrial fibrillation (AF), stroke, these endpoints individually and costs. Of 198 patients (age 77 +/- 10 years, 43% female, ejection fraction 54 +/- 12%, follow-up 38 +/- 15 months), 94 were randomized to SA and 104 to TA. Thirty-two patients (34%) died in the SA group vs. 25 (24%) in the TA (P= ns). QoL showed no differences in all dimensions. The combined secondary endpoint was reached more frequently with SA (51%) compared to TA (37%, P = 0.045). There was no difference regarding all single secondary endpoints. Hardware costs were reduced by 15% (P < 0.0001). CONCLUSION: In long-term follow-up, a TA is equal to SA regarding the primary endpoint QoL and secondary endpoints as AF and mortality. Depending on the healthcare system, it may significantly reduce costs.     

A Management of Early CRPS I Caused by Ankle Sprain: A Case Report

Abstract:   We present a case of a 13-year-old boy who developed signs and symptoms of neuropathic pain/early Complex Regional Pain Syndrome (CRPS) Type I, formerly known as Reflex Sympathetic Dystrophy (RSD), after spraining his ankle while wrestling. Aggressive pain control, using medications and sympatholytic blocks, with physical therapy and rehabilitation, led to the resolution of his painful condition. This prevented the disease from possibly progressing to a full-blown case of CRPS I (RSD) that is very challenging to treat.     

腹茧症的影像诊断

目的探讨腹茧症的影像特点，提高术前诊断水平。方法回顾性分析经手术病理证实的腹茧症6例，术前均进行立位腹部X线平片和腹部CT检查，4例同时行胃肠道钡剂造影，复习其影像表现。结果6例立位腹部X线平片中3例诊断为肠梗阻。4例胃肠道钡剂造影，均可见小肠交错盘绕成团，呈“菜花”状或“手风琴”状表现。6例CT检查，均可见小肠聚集成团，其周围可见膜样的囊状物将其包裹。结论对患者进行胃肠道造影时观察到“菜花”状征象，或CT检查时观察到小肠聚集成团被一层膜样物包裹，应考虑到腹茧症的可能。
