Objective To study the clinical features of duodenal trauma and its surgery to improve the level of diagnosis and treatment. Methods Methods of diagnosis and results of surgical treatment were analysed retrospectively of 35 cases of duodenal trauma. Results The positive rates of abdominal X-ray and abdominal puncture were 32.0%, 13.3% respectively. The extraperitoneal duodenal injuries occured in 30(85.7%) cases. 25(71.4%) cases were complicated by additional intraabdominal organ injuries. The rate of failure to diagnose intraoperatively was 11.4%. The postoperative complication rate was 37.1% and the death rate was 11.4%. Conclusion Duodenal trauma is characteristic of low diagnostic rate preoperatively, high failure rate intraoperatively and most of the cases are complicated by other intraabdominal organ injuries, so both the complication and mortality are high. If the diagnosis is certain, surgery should been taken suitably. This is the key to improve prognosis. The procedure performed is based on the condition of duodenal injuries.
To study bacterial changes of bile, to detect relationship between formation of core of gallstones and bacterial infection. Floras of bacteria in bile were studied in patients with gallstones by using aerobic, anaerobic and Lforms (X, Y,L) culturing system.Results: Bacterial growth positive was found in 88 of 98 patients in which single bacterial growth accounted for 54 cases, multiple growth 34 including type X 83, type L 23 and type Y 5. The results show that some alteration of bacteria flora exists during biliary infection and S. Liguefaoiens and E. Coli are the most frequent bacteria present. Formation of the core of gallstone might be related with bacterial infection.

From Jan. 1980 to Dec. 1996, 138 cases of papillary adenocarcinoma of thyroid gland were surgically treated. To minimize the local recurrence and complication, resection of the involved lobe and the isthmus is an ideal surgical operation. Modified neck lymph node dissection should be performed, if the diameter of primary tumor is larger than 1.5 cm; whether the lymph node is palpable or not. Functional or classical radical neck lymph node excision should be taken, if the neck lymph node can be palpable.
Diagnosis and surgical procedures were studied in this paper. Twentyfive cases of insulinoma were treated surgically from 1970 to 1997, in which 10 patients had Whipple′s triad so that the early diagnosis could be made. The sites of tumours were found in 10 out of 12 undergoing. Selective celiac angiongraphy with the accuracy rate of 83%, but B-ultrasonography and CT gave only 10% (4 out of 25) and 40%(8 out of 20) respectively. In this series, 5 cases underwent bodytail pancreatectomy and 20 cases enucleation of insulinoma. Blood glucose levels were tested during operation in 15 cases, and they all reached the normal level one hour after the tumours were completely removed. The authors consider that Whipple′s triad is the main basis in diagnosis of insulinoma. The selective celiac angiongraphy play an important role in detecting and locating the tumour. If diagnosis is made, surgical operation should be taken. The blood glucose monitoring during operation is the hallmark for complete resection of insulinomas.
Integrating visualization toolkit and the capability of interaction, bidirectional communication and graphics rendering which provided by HTML5, we explored and experimented on the feasibility of remote medical image reconstruction and interaction in pure Web. We prompted server-centric method which did not need to download the big medical data to local connections and avoided considering network transmission pressure and the three-dimensional (3D) rendering capability of client hardware. The method integrated remote medical image reconstruction and interaction into Web seamlessly, which was applicable to lower-end computers and mobile devices. Finally, we tested this method in the Internet and achieved real-time effects. This Web-based 3D reconstruction and interaction method, which crosses over internet terminals and performance limited devices, may be useful for remote medical assistant.
ObjectiveTo explore the reliability and safety of diagnosis and treatment for cholecystocolonic fistula during laparoscopic cholecystectomy. MethodsData of patients with cholecystocolonic fistula in department of general surgery, Gansu provincial hospital from Jan 2002 to Dec 2015 were analyzed retrospectively. There were 112 cases diagnosed by routine intraoperative cholangiography from 11 472 laparoscopic cholecystectomy patients, including 33 males and 79 females, age from 58 to 84 years〔(67.4±12.6) years〕. ResultsOne hundred and twelve cases of cholecystocolonic fistula were diagnosed by routine intraoperative cholangiography in laparoscopic cholecystectomy. There were 105 cases of cholecystocolonic fistula performed laparoscopic cholecystectomy and colon repair, and 7 cases performed colostomy, no surgical complications occurred. Seventy cases were followed-up for 6-27 months〔(16.4±5.3)months〕after operation, no long-term complications occurred. ConclusionsThere is a lack of specific symptoms and special diagnosis for cholecystocolonic fistula before operation. Intraoperative cholangiography is a only objective method for diagnosis, and treatment of cholecystocolonic fistula by laparoscopic cholecystectomy and colon repair or colostomy is safe and reliable based on experienced laparoscopic skill.
ObjectiveTo systematically review the expression and clinical significance of CD133 in gastric cancer. MethodsSearches in the databases such as PubMed, EMbase, Web of Knowledge, The Cochrane Library (Issue 10, 2013), CBM, VIP, CNKI and WanFang Data were performed to collect case-control studies about the association between the CD133 expression and gastric cancer up to October 2013. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and assessed the methodological quality of the included studies, and then RevMan 5.2 software was used for meta-analysis. ResultsNine case-control studies involving 623 patients were included. The results of the meta-analyses showed that, there were significant differences of CD133 expression in the following comparisons:gastric cancer tissues vs. normal esophageal tissues (OR=3.89, 95%CI 1.87 to 8.11, P=0.000 3), lymph node metastasis vs. non-lymph node metastasis (OR=2.75, 95%CI 1.99 to 3.81, P < 0.000 01), clinical stages Ⅲ-Ⅳ vs. clinical stages Ⅰ-Ⅱ (OR=2.83, 95%CI 2.13 to 3.76, P < 0.000 01), as well as distant metastasis vs. non-distant metastasis (OR=2.38, 95%CI 1.47 to 3.85, P=0.000 4). While no significant difference was found between the cell differentiation G1-G2 vs. cell differentiation G3 (OR=1.70, 95%CI 0.90 to 3.21, P=0.10). ConclusionOver-expression of CD133 is associated with lymph node metastasis, distant metastasis and poor TNM stage, which suggests that CD133 may participate in the carcinogenesis of gastric cancer. However, due to the limitations of the included studies, more large-sample high-quality case-control studies are still needed to verify these results.
