To observe the changes of intestinal bacteriology in acute necrotizing pancreatitis (ANP). Dog ANP model was induced by injection of sodium taurocholate with trypin into the pancreatic duct. All dogs were sacrificed on the seventh postoperative day, mucosal and luminal microflora of intestine were analyzed quantitatively. The blood and organs were collected for culture. The results showed that population levels of E.coli in the intestinal mucosa and the content in cecum of the ANP dogs showed much higher level than those of the controls (Ｐ＜0.01 or Ｐ＜0.05), while bifidobacterium and lactobacillus were decreased significantly (Ｐ＜0.01), resulting in reversal of bifidobacterium/E.coli ratio. Blood levels of endotoxin were 1-2 times higher in ANP group as compare with the controls. The positive rate of blood and organs were 100% in ANP dogs. E.coli were the major bacteria cultured. The results indicated that microecological disturbance could take place after the onset of ANP, which may take an important role on pancreatic infection complicating ANP.
The purpose of the study was to observe effect of chinese medicine “Qing Yi Tang” on the repair of injury of intestinal mucosa in acute necrotizing pancreatitis (ANP). Dogs ANP model were induced by injection of 5% sodium taurocholate (0.5 ml/kg) with 3 000 u/kg trypsin into the pancreatic duct. Diamine oxidase and anylase activity in blood, protein and MDA levels of ileal mucosa were to be determined in ANP and after treatment of “Qing Yi Tang”. Intestinal permeability was also to be studied, LPS and bacteria translocation (BT) were obseved. All animals were sacrificed on day 7, the tissue of ileal mocosa was collected for histological and ultrastructural studies. The results showed that after treatment with Chinese medicine “Qing Yi Tang”, the injury of intestinal mucosa in ANP reduced. The length, height, area and protein of ileal mucosa increased significantly, intestinal permenbility decreased, the levels of LPS reduced in 1-2 times, and organ BT rate also reduce in 50%. The results indicated that chinese medicine “Qing Yi Tang” had good effect on improving repair of intestinal mucosa injury, protecting gut barrier function, reducing the incidence of LPS and bacteria translocation.
OBJECTIVE To observe the effects of basic fibroblast growth factor (bFGF) on repairing injury of intestinal mucosa in acute necrotic pancreatitis (ANP). METHODS Sixteen dogs of ANP animal model were made by injection of 5% sodium taurocholate (0.5 ml/kg) with 3,000 U/kg trypsin into the pancreatic duct. The mucosa structure, content of protein, DNA and malondiethylaldehyde (MDA) were observed after ANP and treatment with bFGF, and the plasma lipopolysaccharide and endothelin-1 were detected. The organs of dogs were made to bacterial culture. Ileal mucosa was collected for histological and ultrastructural studies. RESULTS The results showed that after treatment with bFGF, the injury of intestinal mucosa in ANP was abated. The length, height and area of mucosa microvillus, the content of DNA and protein of ileal mucosa were significantly increased, while the plasma endothelin-1 and lipopolysaccharide were reduced. The organ bacterial translocation rate was also decreased in 50%. CONCLUSION bFGF has good effects on abating injury of intestinal mucosa, protecting gut barrier function, reducing the incidence of lipopolysaccharide and bacterial translocation after ANP.
目的探讨原发性骶前肿瘤的诊断与治疗方法。方法回顾性分析1979~2001年间收治的12例原发性骶前肿瘤患者的临床资料。结果直肠指诊、B超、CT检查阳性者分别为10/12、 12/12及6/6； 肿瘤完全切除者9例，部分切除者2例，肿瘤未能切除仅行隐性乙状结肠造口术1例。经病理组织学检查，12例中畸胎瘤4例，上皮样囊肿5例，恶性淋巴瘤1例，神经纤维瘤1例，神经纤维肉瘤1例； 8例术后平均随访14个月，治愈6例，好转2例,无手术死亡。结论原发性骶前肿瘤临床表现不典型，直肠指诊、B超及CT检查有助于诊断； 完全切除是治疗原发性骶前肿瘤的主要措施。
【Abstract】ObjectiveTo detect the spreading scope of rectal cancer to mesorectum by RT-PCR using carcinoembryonic antigen (CEA) mRNA as a marker and to investigate the excision scope of mesorectum in resection of rectal cancer. MethodsForty specimens from 40 rectal cancer patients who underwent curative operation was employed to detect the metastatic deposits scattered in the mesorectum by RT-PCR using CEA as a marker. ResultsNine of 40 (22.5%) specimens contained metastatic deposits scattered in the mesorectum. The metastasis was just within the range of 4cm mesorectum under the verge of tumor. The tumor spreading to mesorectum is correlated with Dukes stages，the infiltrated depth of bowel wall, tumor differentiation and tumor type(P＜0.05), and is not correlated with the size of tumor and the level of CEA(Pgt;0.05). ConclusionThe excision of mesorectum should be within the range of 5cm under the verge of tumor in surgical management of rectal cancer.
【摘要】目的探讨十二指肠憩室的诊断与治疗。方法对南方医院1982～2002年20年期间收治的110例十二指肠憩室患者的临床资料作回顾性分析。结果憩室分布于十二指肠球部10例，降部77例，水平部15例，升部8例； 憩室合并炎症28例，合并出血14例，合并急、慢性胆胰疾病35例，无合并症33例。手术治疗47例，其中行十二指肠憩室切除术10例，憩室内翻缝合术5例，胃大部切除术13例，胃大部切除+胆肠RouxenY吻合术10例，Oddi氏括约肌成形术2例，胃大部切除+胆囊切除术5例，胰十二指肠切除术2例。术后发生十二指肠瘘1例，手术治疗47例全部治愈，无一例死亡。结论十二指肠憩室以降部多发，无症状者可行保守治疗，若合并炎症、出血、胆胰疾病，则需根据憩室部位合理选择手术方式。
