ObjectiveTo evaluate a second endoscopy for prevention of delayed bleeding after ESD.MethodsData of 67 patients with gastric epithelial neoplasms undergoing ESD from May to November 2011 were reviewed.The median age was 63 ( 31 ~ 84) years.All patients were followed up by endoscopy on the first and the third day after ESD.ResultsOf 67 lesions,5 were located at cardia,6 at gastric body,3 at fundus,35 at antrum,16 at gastric angle,and 2 at residual stomach.The mean maximum diameter of the lesions was 3.73±4 1.24 (2.0 ~ 7.0) cm.There were no intraoperative complications.Post-ESD delayed bleeding was detected by endoscopy in 6 (9.0% ) patients,with 5 on the third day and 1 on the fourth day.Forrest grading showed 2 cases of Ⅰ b,and 4 of Ⅱ b.All 6 cases were cured by endoscopy.The incidence of postoperative bleeding was far more than that evaluated based on the patients' clinical manifestations only.But therapeutic effect and saffety were the same according to the follow-up results.ConclusionIncidence of post-ESD bleeding is high,but there are no symptoms or severe consequences,so a second endoscopy after gastric ESD may contribute little to the prevention of delayed bleeding.

OBJECTIVETo study the protective effects of garlic oil (GO) on the peripheral nerve injuries induced by n-hexane.
METHODSMale Wistar rats were randomly divided into four groups (10 rats in each group): the control, the n-hexane treatment (2000 mg/kg), the low dose GO, and the high dose GO groups. The rats in the low and high doses of GO groups were pretreated with GO (40 and 80 mg/kg) before exposure to n-hexane (2000 mg/ kg), while the animals of the n-hexane treatment group were given normal saline and then 2000 mg/ kg n-hexane. The rats were exposed to GO and n-hexane 6 times a week for 10 weeks. The gait scores and staying time on the rotating rod for all rats were detected every two weeks. The rats were sacrificed at the end of ten weeks, then the levels of alcohol dehydrogenase (ADH), maleic dialdehyde (MDA), reduced glutathione (GSH), glutathione peroxidase(GSH-Px), total antioxidation capacity(T-AOC) and the ability of inhibition of *OH in livers were examined.
RESULTSThe gait scores increased significantly and the time staying on the rotating rod obviously decreased in rats of n-hexane treatment group, as compared with control group (P < 0.05 or P < 0.01). In the hepatic tissues of n-hexane group, the levels of MDA and ADH significantly increased, the activities of GSH-Px, T-AOC and the ability of inhibition of *OH obviously decreased, as compared to control group (P < 0.05 or P < 0.01). In 2 GO groups, the gait scores and the staying time on the rotating rod were significantly improved, the levels of MDA and ADH significantly decreased, the activities of GSH-Px, T-AOC and the ability of inhibition of *OH obviously increased, as compared with n-hexane group (P < 0.05 or P < 0.01 ).
CONCLUSIONADH could play an important role in the protective effects induced by garlic oil on the peripheral nerve injuries produced by n-hexane.

OBJECTIVETo investigate the value of CT and X-ray enterography in the diagnosis of small intestinal Crohn disease(CD).
METHODSData of 39 CD cases confirmed by surgery and pathology who underwent CT and X-ray enterography were analyzed retrospectively. All the patients had complete CT data, 28 cases had X-ray intestinal barium meal data, and 18 had sinus tract enterography.
RESULTSCT enterography showed mural thickening(>4 mm) in 34(87.2%) patients, mural gas in 7(17.9%), mural edema in 7(17.9%), mural fat in 4(10.3%), increased enhancement of bowel wall(>10 HU) in 37(94.9%), multiple segmental lesions in 33(84.6%), single segmental lesions in 6(15.4%), mesenteric lymphadenopathy(>5 mm) in 13(33.3%), vascular bundle thickening in 9(23.1%), cellulitis in 12(30.8%), peritoneal abscess in 10(25.6%), phlegmon in 8(20.5%), incomplete intestinal obstruction in 14(35.9%), seroperitoneum in 22(56.4%), and fistulization in 4(10.3%). CT enterography did not demonstrate the change of mucosa such as strip ulcer or cobblestone. Among the 28 cases of small bowel X-ray enterography, 23 cases(82.1%) presented with multiple segmental lesions, 5(17.9%) with single segmental lesions, 18(64.3%) with strip ulcer, 16(57.1%) with cobblestones, 4(14.3%) with intestinal fistula, while no bowel wall and extraintestinal complication of CD disease was observed. Among the 18 cases of sinus tract enterography, 13 cases (72.2%) presented with intestinal fistula, 12(66.7%) with peritoneal abscess, 8(44.4%) with sinus tract.
CONCLUSIONSCT enterography can demonstrate exactly the diseased bowel wall and extraintestinal complication of CD disease, which is important to evaluate the extent of CD and guide the treatment, however strip ulcer and cobblestone sign cannot be demonstrated. The X-ray enterography is available to demonstrate the characteristic changes of CD such as trip ulcers and cobblestones, but is difficult to show the bowel wall and extraintestinal inflammatory mass and abscesses. The sinus tract enterography is easy to demonstrate the intestinal fistula and intra-abdominal abscess. Combination of these methods is more beneficial to guild the diagnosis and treatment.
