Objective To improve the diagnosis and treatment of primary adenocarcinoma of the duodenum. MethodsLiteratures were reviewed.ResultsThe morbidity of primary duodenal adenocarcinoma was low and its clinical manifestation had no characteristics.The most effective methods in the diagnosis of the disease were gastrointestinal radiography and endoscopy with the accuracy of 88% and 89% respectively.The disease could be cured by resection of the lesion. The selection of operative type depended on the stage and position of the tumor.Radical resection and tumor stage played an important role in the prognosis.Conclusion Early diagnosis and rational operation are the major ways to improve the resectability and to modify the therapeutic result.
Objective To investigate the diabetic knowledge of primary hospital doctors and diabetes patients, and to explore the way to improve the capability of primary hospitals in preventing and treating diabetes. Methods Between January 2013 and June 2014, we set questionnaires to learn the profiles of diabetes knowledge of 328 internal and general medicine doctors including 43 chronic disease management workers from fifteen township hospitals and two community health centers, 152 doctors from village clinics, and 575 diabetes patients in Xindu District of Chengdu City. We made questionnaires for doctors and patients respectively to investigate their knowledge on diabetes and blood sugar control in the patients. Finally, we made plans to train doctors in primary hospitals according to the results of the investigation. Results For township hospitals, 328 questionnaires were given out with 319 retrieved, and the valid retrieval rate was 97.3%; 152 questionnaires were given out to village doctors and 149 were retrieved, with a valid retrieval rate of 98.0%; and we gave out 575 questionnaires to the diabetes patients and retrieved 539, with a valid retrieval rate of 93.7%. Primary hospitals were insufficient in their drug varieties. Among doctors in township hospitals, 7.8% had bachelor’s degree, 53.6% had received post-secondary education, and 38.6% had received secondary vocational education. Most of the village doctors had not received any professional medical education, among whom, 89.9% had a certificate of village doctors and 10.1% had a certificate of assistant doctors. The diabetes questionnaire score of primary hospital doctors was low, while the score of chronic disease management workers was relatively higher (P<0.05). For diabetes patients, medical investment was inadequate, treatment rate was low, common sense of diabetes was insufficient, and glycosylated hemoglobin control rate was only 13.5%. Conclusions Diabetes patients in primary hospitals have a poor disease control, which is probably associated with the insufficient publicity and education from doctors. It is necessary to train primary hospital doctors at all levels. In order to get the best therapeutic effect, we advocate that diabetes should be managed by doctors of chronic disease management, although they should receive systematic training for a long time.
【Abstract】ObjectiveTo explore risk factors of bile leakage after primary ductal closure following choledochotomy. MethodsA retrospective clinical analysis was made in 148 cases of Ttube drainage and 154 cases of primary common bile duct suture following choledochotomy admitted to our hospital from January 1999 to June 2003. Results Postoperative bile leakage was seen in 11 patients of the group with Ttube drainage and in 16 patients of the group with primary suture respectively, there was no significant difference(Pgt;0.05).In the group with primary common bile duct suture,the occurrence of bile leakage was relative with hyperglycemia(Plt;0.05)，hypoproteinemia (Plt;0.01)，bile duct repeated sutures(Plt;0.01)and positive bacterial culture in bile(Plt;0.05). Bile leakage was not relative with elder age (Pgt;0.05).Conclusion It is the key factors,including chosing appropriate patients, intraoperative special examination, careful manipulation and effective medical treatment that can reduce the morbidity of bile leakage.

Objective To explore the correlation of risk factors affecting the L2-4BMD level in patients with post-menopausal osteoporosis. Methods Ninety-two patients with post-menopausal osteoporosis were surveyed with a retrospective questionnaire. We used the findings to set up a multiple stepwise regression model and perform correlation analysis with L2-4BMD levels as the dependent variable and risk factors as the independent variables. Results Assuming that age has a definite effect on the L2-4BMD level of menopausal women, menopausal age limit, history of milk drinking, menopausal age, menarche age, fracture history and bend-back entered into the multiple stepwise regression equation. Conclusions Menopausal age limit, history of milk drinking, menopausal age, menarche age, fracture history, and bend-back influence patients with menopausal osteoporosis.The menopausal age limit is especially important. Awareness of the risk factors of osteoporosis should be raised.

【Abstract】ObjectiveTo evaluate the value of MR imaging with a contrast-enhanced multi-phasic isotropic volumetric interpolated breath-hold examination (VIBE) in diagnosis of primary liver carcinoma. MethodsThirty-two consecutive patients with surgical-pathologically confirmed 42 foci of primary carcinoma of liver underwent comprehensive MR examination of the upper abdomen, routine two-dimensional (2D) T1WI and T2WI images were acquired before administration of Gd-DTPA for contrast enhancement. Then, contrast-enhanced multi-phasic VIBE was acquired followed by 2D T1WI images. The lesion appearances on hepatic arterial, portal venous and equilibrium phases of VIBE sequence were carefully observed along with delineation of hepatic arterial and portal venous structures. The lesion detection rates and lesion characterization ability were compared among various MR sequences. Results33(78.6%), 30(71.4%), 38(90.5%) and 42(100%) foci were displayed respectively on T2WI, non-enhanced T1WI, enhanced T1WI and enhanced 3D-VIBE images (P＜0.05). The hepatic arterial anatomy of 30 patients （93.8%） and the portal venous structure of 31 patients （96.9%） were clearly depicted on enhanced 3D-VIBE images. Using MIP and MPR reconstruction techniques, the feeding arteries of 14 foci and draining vein of 12 foci were clearly displayed.ConclusionHigh-quality 3D-VIBE images are not only better than 2D images in lesion detection and characterization for primary liver carcinoma, but also able to provide much more information about hepatic vascular anatomy.
Objective To study the effects of pcDNA3/AFP/TK/Angio fusion gene targeting therapy for human primary liver cancer in nude mice implanted with SMMC-7721. Methods Human liver cancer cell line SMMC-7721 was implanted subcutaneously in nude mice to establish experiment model. Animals bearing liver cancer were randomly divided into five groups: control group， vector group， GCV (ganciclovir) group， pcDNA3/TK/Angio group; pcDNA3/AFP/TK/Angio group. Different plasmids were directly injected into tumors and GCV was intraperitoneally administrated simultaneously according to different groups. The growth of tumors was observed and the pathology was examined as well. Serum AFP level was measured by radioimmunology, the ultrastructural change of tumor cells was studied by using electron microscopy, the expressions of MVD and VEGF were respectively detected with immunohistochemistry and the cell apoptosis in situ was detected by TUNEL. Results The success rate to establish subcutaneous implanted liver cancer model in nude mice was 100%. The tumor volume, serum AFP level, VEGF and MVD expressions of pcDNA3/TK/Angio group and pcDNA3/AFP/TK/Angio group were lower than those in control group, vector group and GCV group (P＜0.05) and more apoptosis cells could be observed. While the tumor volume, serum AFP level, VEGF and MVD expressions of pcDNA3/AFP/TK/Angio group was lower than those in pcDNA3/TK/Angio group (P＜0.05); and apoptosis index was higher than that of the latter (P＜0.05).Conclusion pcDNA3/AFP/TK/Angio fusion gene inhibits the growth of tumor remarkably and becomes a promising new biological agent to treat human primary liver cancer.
Objective To study the efficiency of percutaneous acetic acid injection (PAI) or percutaneous ethanol injection (PEI) in the treatment of primary hepatic carcinoma (PHC). Methods Seventeen and 24 patients with PHC were treated, respectively by PAI or by PEI in our hospital. According to hepatic function test, soluble intereukin-2 receptor (sIL-2R), AFP, biopsy and size of tumor, the evaluation was made.Results Effective rate was 88.2% in PAI group and 87.5% in PEI group, respectively. There was no obvious influence to sIL-2R in serum in the two groups (Ｐ＞0.05). Obvious differences in impairment of hepatic functions between PAI and PEI groups were found (Ｐ＜0.01), it also showed that smaller amounts of acetic acid and less puncture frequency were required for the treatment than that of ethanol. Conclusion PAI is superior to PEI in the treatment of those patients who are complicated with cirrhosis or other vital disease.
ObjectiveTo evaluate the safety and feasibility of laparoscopic resection of primary retroperitoneal tumors. MethodClinical data of 52 patients diagnosed as primary retroperitoneal tumor who underwent laparoscopic resection in Peking University Third Hospital from January 2006 to December 2015 were retrospectively collected and analyzed. ResultsFifty two patients were included in the review. In 21 patients (40.3%), tumors were adjacent to major vessels (such as inferior vena cava, superior mesenteric vein, and the splenic vessel), tumors of 31 patients (59.7%) were away from major vessles. Two operations (3.8%) were converted to hand-assistant and 2 operations (3.8%) were converted to laparotomy due to tight adherence to major vessels. The mean value of operative time was 171.4-minute (60-520 minutes) and the mean value of length of incision was 2.8 cm (1-15 cm), the mean value of estimated blood loss was 86.4 mL (10-1 150 mL), 2 patients needed blood transfusion. The mean value of time of returning to diets was 1.5-day (1-5 days) and the mean value of length of postoperative hospital stay was 4.9-day (1-16 days). There was no major postoperative complications or death. Follow up was available for 47 patients at a median time of 62.0-month (4-120 months). Three patients with retroperitoneal liposarcomas experienced recurrence at 31, 34, and 48 months after operation, 1 patient with mucinous peripheral neurilemmoma experience recurrence at 69 months after operation, all of which underwent further resection, with others experiencing no recurrence or metastasis. Three patients died in reason of other diseases. ConclusionsLaparoscopic surgery can be performed safely in the treatment of primary retroperitoneal tumors, even when a tumor adjacent to major vascular structures.
