Objective To compare the clinical effects of palliative drainage to pancreatic and periampullary carcinoma which could not be excised with the operation.Methotis A retrospective study was accomplished on the palliative drainage treatment of 68 patients with pancreatic and petiampullary carcinoma hospitalized from 1996 to 2003.Results The disease course was two days to eight months.A definite preoperative diagnosis was made for 64 cases.Among them.single test diagnosed 24 cases and multiple tests diagnosed 40 cases.56 patients suffered from jaundice before operation.34 patients were treated by Roux-Y choledochojejunostomy.Choledochoduodenostomy was performed in 16 patients,cholecystduodenostomy for biliary by pass Was performed in 8 patients and stented internal drainage of the biliary duct in the liver and duodenostomy was performed in 10 patients.After reducing jaundice,12 patients was performed surgical resection.The second operation was performed in 4 patients because of postoperative jaundice and in 3 patients because of pylofic obstruction.The pefioperative compllcations include 4 cases of jaundice pyloric,3 cases of obstruction,2 cases of postoperative bleeding and 5 cases of infection of incisional wound.The aver-age stay in hospital waa 13.3 days(8～22 days).Conclusion Multiple tests were helpful to make a definite preoper-ative diagnosis.The selection of palliative drainage method based on the condition of patients had good curative effect in clinic.Surgocal exploration and reducing jaundice could set win conditions for second operation.

Objective To study the relationship between Epstein-Barr virus(EBV) and Hapatocellular carcinoma (HCC). Methods Polymerase chain reaction (PCR) and immunohistochemical staining were applied to detect EBV in paraffin tissue sections from 78 HCC patients. Results EBV DNA was detected in 22 patients (28 2%) by PCR. Immunohistochemical staining of EBV LMP1 revealed that the positive signals were mainly localized in the tumor cells. Conclusions These observations suggest that EBV may pay a role in the development of HCC.

Objective To investigate the effect of hyperbaric oxygen to reduce stress-induced gastric mucosal injury in rabbits with blast-related brain injury.Methods Posttraumatic stress ulcer in a rabbit model of blast-related brain injury was created using paper detonators.Ninety New Zealand white rabbits were randomly divided into normal control group (n =10),blast-related injury group (n =40) and hyperbaric oxygen treatment group (hyperbaric oxygen group,n =40) according to the random number table.Rabbits in blast-related injury group and hyperbaric oxygen group were subgrouped at 6 hours,24 hours,72 hours and 7 days postinjury,with 10 rabbits at each time point.Gastric mucosal injury was detected in aspects of ulcer index,TUNEL method for apoptotic index,and alcian blue-periodic acid-schiff (AB/PAS) staining and semi-quantitative analysis of pathological histology using.Results Neither stress ulcer nor apoptosis occurred in normal control group.At 6 hours,24 hours,72 hours and 7 days postinjury,index of gastric ulcer in blast-related injury group was 12.08 ± 1.02,25.56 ± 0.88,20.36 ±0.96 and 17.56 ± 1.12 respectively,far higher than 8.02 ±0.58,15.22 ± 1.05,12.39 ±0.65 and 9.22 ± 0.79 in hyperbaric oxygen group (P ＜ 0.05) ; apoptotic index in blast-related injury group was 20.22 ± 1.56,27.56 ± 0.96,24.36 ± 1.23 and 16.38 ± 1.24,far higher than 10.78 ± 0.93,13.89 ±0.84,10.55 ± 1.58 and 8.56 ± 1.47 in hyperbaric oxygen group (P ＜ 0.05).Thickness of AB/PAS-positive mucin layers showed marked attenuation even loss in blast-related injury group,but the loss was minor in hyperbaric oxygen group (P ＜ 0.05).Conclusion Hyperbaric oxygen is effective to decrease the stress ulcer index and apoptosis index of gastric mucosa,increase the thickness of AB/PAS positive layer and lighten the gastric mucosal injury of rabbits with blast-related brain injury.

Objective To investigate the method of surgical treatment of acute intestinal obstruction caused by colorectal cancer,and affirm the feasibility and validity of the new way ofearly precolonic postoperative enteral nutritionafter operation of acute intestinal obstruction caused by colorectal cancer.Methods Retrospective analized the clinical data of 78 cases of acute intestinal obstruction caused by colorectal caner from September 2007 to September 2012 and the incidence of complications (incision infection,intra-abdominal abscess,anastomotic leakage,and pneumonia) was observed.Results Sixty-two patients received radical resection and primary anastomosis.All of them were cured and no death occurred.Two patients had complication of postoperative infection and none suffered from anastomotic or drainage leakage.Conclusion Radical resection and primary anastomosis using Intra-operative colonic lavage are safe and effective methods for patients with colorectal cancer associated with acute intestinal obstruction,and early precolonic postoperative enteral nutritioncould better eliminate perioperative malnourished patients more,reduce operation complication,prevent anastomotic leakage,and increase the success rate of the operation.

Objective To compare the clinical outcome of procedure for prolapse and hemorrhoids (PPH) and PPH + selective Milligan-Morgan hemorrhoidectomy(MMH) in surgical treatment of Ⅲ ～ Ⅳ stage hemorrhoids and research the best surgical procedures.Methods Retrospective analysis was made on the clinical data of 125 cases with Ⅲ ～ Ⅳ stage mixed hemorrhoids,they were non-randomized-controlled divided into PPH group (group 1) and PPH + selective MMH group(group 2),comparing the data of recurrence,complication and symptoms relief including anal prolapse,bleeding,anus fall feeling,wet anus and pruritus ani.Results While observing 3 years after operation,group 1 and group 2 both relieved symptoms of anal prolapse,bleeding,anus fall feeling,wet anus and pruritus ani.The relief rate of these symptoms in the two group were all high than 92%.There was one cases relapsed in the group 2 (the recurrence rate of 2%) was better than the group 1 (the recurrence rate of 13%) which were 8 case,there was a significant statistical significance (x2 =4.629,P ＜ 0.05) in the recurrence and clinical outcome.Conclusion Radical choose of PPH and selective MMH to treat Ⅲ ～ Ⅳ stage mixed hemorrhoids patients,which could relieve postoperative symptoms and acquire better long-term clinic outcomes.

Objective To evaluate the feasibility of endooscopic minimally invasive McKeown esophagectomy in the treatment of esophageal carcinoma. Methods From June 2012 to August 2015, the data of 180 patients with esophageal carcinoma was retrospectively analyzed. The patients were divided into endoscopy McKeown esophagectomy group (EME group) and open McKeown esophagectomy group (OME group), each group had 90 patients. The clinical pathological data, perioperative data and postoperative complications between the two groups were analyzed. Results The operation time in EME group was longer than that in OME group [(289 ± 30) min vs. (252 ± 28) min, t= 8.063, P< 0.05]. The intraoperative blood loss and postoperative blood loss on the first day after operation in EME group were less than those in OME group [(178.94 ± 47.84) ml vs. (323.44 ± 59.51) ml, t=17.952, P<0.05; (220.93 ± 49.07) ml vs. (362.59 ± 68.37) ml, t= -15.968, P< 0.05]. There was no significant difference between the two groups in the number of lymph node dissection (t= -1.913), postoperative hospitalization days (χ2= 4.858) and postoperative complications (exact probability method) (all P> 0.05). Conclusions Endoscopic minimally invasive McKeown esophagectomy has the same effect as open surgery, and trauma is small. Therefore, for the patients who are suitable for the minimally invasive surgery, it can be preferred.

AIM: To establish a capillary GC-FID programmed temperature method for determining eugenol in Bawei Tanxiang Pills(Lignum Santali Albi, Flos Caryophylii, etc.). METHODS: Chromatography was performed on a 25m?0.25mm(0.25?m film thickness), SE-54 fused-silica capillary column coupled with a FID-detector. The internal standard was cyclohexanone. RESULTS: A good linearity was obtained in the range of 0.25?g～8?g of Eugenol with a correlation coefficient of 0.9993. The average recovery was 96.5%, the RSD was 2.4%. CONCLUSION: The established method was provided to be a reliable quantitative method for quality control of Bawei Tanxiang Pills.
