ABSTRACT
Objective To sum up the experience of diagnosis and treatment of paraduodenal hernia. Methods The clinical data of 18 cases of paraduodenal hernia treated by surgery were analyzed retrospectively. Results The average age of the patients was 34 years old.There were 15 cases with left paraduodenal hernia and 3 cases with right paraduodenal hernia.Ten patients usually had no clinical symptoms,while acute abdominal pain occurred after full food in 7 cases,and after vigorous movement in 10 cases respectively.Abdominal X-ray revealed complete or incomplete intestinal obstruction in 16 cases,while abdominal CT revealed abnormal cystic loops of small intestine between the pancreas and the stomach in 10 cases.All 18 cases underwent surgical operation,recovered 10-15 days after operation.After 2-8 years follow-up,there was no hernia recurrence.Conclusion Paraduodenal her-nia is difficult to diagnosis before operation,and the key to correct diagnosis and treatment is to explore the positive exploratory laparotomy.
ABSTRACT
Objective To construct the adenovirus vector containing mice CD40- IgG2aFc-IRS-GFP fusion gene and detect the expression of the fusion protein in transfeete 293cells.Methods The fragments of CD40, IgG2aFc were obtained and inserted into plasmid PDC316-IgG2aFc-GFP.After being verified by sequencing, Ad5-PDC316-CD40-IgG2aFc-GFP was contransfored with the bckbone vector into 293 cells.The virus titer was detected after replicating and purifing and the expression of the fusion protein was analyzed.Results A virus and plasmid were constructed successfully.The vitro infection showed that the virus can infect cells of which the fusion protein was confirmed by fluo-rescence.The expression of the fusion protein increased with the increased time and virus concentra-tion.The protein expression stopped increasing after the virus concentration came to a certain level.Conclusion CD40, IgG2aFc fragments are correctly ligated with plasmid PDC316-IgG2aFc-GFP, and the fusion protein can be expressed in 293cells.This might lay a foundation for further studies of the expresstion of virus, immune tolerance and mechanism of liver transplantation model in rats.
ABSTRACT
Objective To observe the efficacy of endoscopic resection with thyroid benign tumor. Methods 60 cases of thyroid benign tumor were randomly divided into the endoscopic group and the traditional group, 30 cases in each group. The operation time, blood loss ,drainage volume, postoperative hospital stay, postoperative complications and hospitalization expenses in two groups were compared. Results There was no significant difference ( P >0. 05) between the two groups of postoperative hospital stay; endoscopic group blood loss (25.3 ± 15.6) ml significantly less than the traditional group (57. 2 ± 33. 8) ml, the difference was statistically significant ( P < 0. 05); endoscopic postoperative drainage volume ( 85.6 ± 53.2) ml significantly more than the traditional group ( 23. 5 ±37.2) ml (P < 0. 05); endoscopic operative time of ( 105.3 ± 23. 5) min, while the traditional group ( 80. 4 ±25. 3 ) min, the difference was significant ( P < 0. 05 ); hospitalization costs were significantly higher than conventional endoscopy group ( P < 0. 05). Both groups were not have obvious complications postoperation. Conclusion Compared with traditional open surgery, endoscopic surgery for benign thyroid tumors has advantages of superior cosmetic results and less bleeding,it is a good choice for the treatment of the disease.
