Changes of Intestinal Caicitonin Gene-related Peptide in Acute Intestinal Radiation Sickness in Rats
The characteristic distribution of calcitonin gone-related peptide(CGRP)inthe small intestine of rats and its changes in acute intestinal radiation sickness(AIRS)were studied with immunocytochemistry(whole mount stretch preparations of the smallintestine and cryostat sections)and radio-immunoassay.It was found that in all the lay-ers of the intestinal walls,there were large amounts of CGRP immunoreactive(CGRP-I)nerve fibers which existed in especiaUy high density in the myenteric,submucosal andmucosal plexuses.There was also a rather high density of the nerves around the smallvessels of the small intestine and the intestinal crypts.Some CGRP-I neurons were seenin the myenteric and submucosal plexuses.In AIRS,the intestinal CGRP showed a dip-hasic change,in a lower level in the 24th h and a higher level in the 48th and 72nd h af-ter irradiation.The results indicate that CGRP may be related to the regulation of the motility,se-cretion,absorption,sensation,and regional blood flow of the gastrointestinal tract.Pro-bably,CGRP is released under the stress of AIRS and participates in the mechanism ofinjury through many ways especially through the influence on the regional blood flowand the increase of the permeability of blood vessels. 相似文献

Summary Obturator hernias comprise a rare group of abdominal hernias. They are often diagnosed when the small bowel has become obstructed
and the patients are operated on without the causes of the obstruction being known. Although many techniques for closure of
the defect are available, there is no agreement at the present time as to which is the procedure of choice. 相似文献

Background: For patients with incurable malignant gastric outlet obstruction and cholestasis, laparoscopic gastrojejunostomy combined
with endoscopic biliary stent placement seems to offer a minimally invasive palliation.
Methods: We retrospectively analyzed the data of 16 patients submitted to laparoscopic gastrojejunostomy. Laparoscopic gastroenterostomy
was performed as an antecolic, side-to-side gastrojejunostomy with enteroenterostomy. In 12 patients cholestasis was relieved
preoperatively by stent placement via endoscopy (n= 6, 37.5%), percutaneous access (n= 5, 31%) or bilioenteric anastomosis (n= 1, 6.25%). One patient needed a percutaneous Yamakawa prosthesis postoperatively.
Results: Mean operative time was 126 min. There were no intraoperative complications. In one patient conversion to open surgery became
necessary because of extensive adhesions. The only postoperative complication was bleeding from a trocar site requiring reintervention;
there was no mortality. Median postoperative hospital stay was 7 days. Delayed gastric emptying was observed in 3 (18.7%)
patients. Median survival was 87 days after the operation. All patients died from their primary disease but could maintain
oral intake during the remaining survival time.
Conclusions: We conclude that laparoscopic gastrojejunostomy and endoscopic or percutaneous biliary stenting provide a good functional
result while impairing the quality of life only to a minimal extent.

162例气管插管患者的气道管理 总被引:16,自引:2,他引:14
笔者通过报道162例气管插管患者的气道管理,阐述痰痂形成的原因:(1)气道干燥,湿化不够。(2)吸痰管插入深度不够,吸痰不彻底。管理措施:(1)用金霉素眼膏润滑吸痰管,使之易于插入,保证吸痰管插入深度超过插管远端3-5cm。(2)预防气道干燥,注重湿化效果,重视吸痰环节。认为气囊不需定时放气,只需不定时调整气囊压力。 相似文献

急性左半结肠癌梗阻一期切除吻合治疗39例 总被引:1,自引:0,他引:1
魏云志 《天津医科大学学报》2003,9(1):106-107
目的:探讨左半结肠癌致急性肠梗阻的手术处理方法。方法:回顾分析1995-2001年间39例左半结肠癌致肠梗阻一期切除吻合术的外科临床效果。结果:全组39例病人均采用梗阻近端肠管减压灌洗,并留置盲肠造瘘管术后接负压吸引,术后均一期愈合,未出现吻合口漏。随访2例中,1例存活率58%,3年存活率16%,5年存活率8%。结论:严格掌握手术适应症和基本操作,在病情允许时,对左半结肠癌急性肠梗阻行一期切除吻合手术是可行的。 相似文献

The term cast syndrome is used to denote duodenal obstruction occurring after application of a corrective plaster cast to patients with scoliosis. We report a classical case in a 14-year-old female who required surgical intervention after conservative treatment failed. Six months later the patient had no further gastrointestinal symptoms. Clinical, radiological, and pathological details as well as the surgical treatment are described and discussed.

动脉自旋标记法磁共振成像在颈动脉狭窄性脑缺血疾病中的初步应用 总被引:2,自引:0,他引:2
目的:对比研究颈动脉严重狭窄患者动脉自旋标记法(ASL)和动态磁化率效应对比剂增强(DSC)磁共振脑灌注成像表现,探讨ASL的临床运用价值。材料和方法:健康自愿者12例,行DSC和ASL,计算左侧大脑中动脉供血区与右侧相应区域相对脑血流量(rCBF)比值并进行比较。病例组为单侧颈内动脉狭窄程度≥70%患者32例,计算DSC和ASL所得的患侧与健侧大脑中动脉供血区rCBF比值并进行比较。结果:12例健康自愿者所测的DSC和ASL的rCBF比值分别为1.0012±0.1030和1.0015±0.1611,无统计学差异。32例患者中,15例患者灌注异常,DSC与ASL的rCBF比值相比无显著性差异(P=0.072)。结论:ASL序列能快速无创的提供脑灌注情况,可作为初步了解颈动脉狭窄性脑缺血疾病脑灌注情况的常规检查方法。 相似文献
