Objective To evaluate the diagnostic procedures and treatment choice of primary malignant tumor of the duodenum.Methods The clinical data of 54 cases with primary malignant tumor of the duodenum at Peking University People's Hospital from 1995 to 2005 were analyzed retrospectively.Resuits Tumors located in the first,second,third and fourth parts in 6 cases(10%),44 cases(82%),2 cases(4%),and 2 cases(4%)respectively,and among them,tumors within papillary area accounted for 86%(38 cases)of all cases.Fifty cases(92%)were of adenocarcinoma,2 cases(4%)of mucinous adenoearcinoma carcinoid and undifferentiated carcinoma for 1 case each(2%)respectively.The main clinical presentations included jaundice,upper abdominal pain,weight loss,abdominal distention,nausea and vomiting.gastrointestinal obstruction and abdominal mass.The accuracy rate of duodenoscopy and ERCP in preoperative diagnosis was 94%,and 78%respectively.Preoperative associated cholecystopathy accounted for 37%.Panceaticoduodenectomy was performed in 38 cases,duodenectonmy in 1 ease,palliative resection of tumor in 9 cases,and tumor was inoperable in 6 cases.Resection rate was 89%,and radical resection rate was 72%.The postoperative 3-and 5-year survival rate was 41%and 22%respectively.Patients after palliative resection died from 3 months to 24 months and all patients who did not undergo a surgery died within 6 months.Conclusions Tumors located in papillary region account for the majority of primary malignant tumors of the duodenum and are mainly of adenocarcinoma.Specific signs on abdominal examination are few.The symptoms of advanced stage are complicated,associated cholecystopathy is relatively frequent.Endoscopy and ERCP examination are the main diagnostic tools.the pancreatoduodenectomy is the first choice of therapy for patients with primary duodenal carcinoma.

Objective To study peripheral blood lymphocytic ?-adrenoceptor(?-AR) densities and ?_1-adrenoceptor gene(?_1-AR mRNA) expression levels in patients with heart failure,to investigate the influences of different ?-adrenoceptor antagonists in ?-AR densities and ?_1-AR mRNA expression levels.Methods 104 cases of patients with heart failure were randomly divided into non-?-adrenoceptor antagonist group(35 cases),metoprolol group(34 cases) and carvedilol group(35 cases),we repeatly determined the ?-AR densities and ?_1-AR mRNA expression levels after two-month therapy.Results The ?-AR densities and ?_1-AR mRNA expression levels in heart failure group reduced significantly compared to these in normal persons(P0.05).After two-month therapy,?-AR densities and ?_1-AR mRNA expression levels in metoprolol group were significantly higher than those in carvendilol group and non-?-adrenoceptor antagonist group(P0.05).Conclusions The peripheral blood lymphocytic ?-AR densities and ?_1-AR mRNA expression level down-regulates in heart failure,which correlate with the severity of heart failure but etiological factors.Metoprolol can up-regulate the ?-AR densities and ?_1-AR mRNA expression level,whereas carvedilol has no such effects.

Objective To evaluate the experience in the diagnosis and surgical treatment of primary retroperitoneal tumor (PRT). Methods Clinical data of PRT 63 cases from January 1990 to March 2007 confirmed by pathology were retrospectively analyzed including clinical manifestation, surgical procedures, pathological examination and follow-up. Results Tumors were benign in 25 patients and malignant in 38. The main symptoms and signs were abdominal mass. The Youdon's index of CT examination for distinguishing benign from malignant tumors was 85%. The complete surgical resection rate was 88% for benign tumors and 68% for malignances. Removal of the involved organs or vessels was needed in 40% patients in complete surgical resection group. Postoperative recurrence was high in those the tumor was not completely removed and those the tumor was malignant. The 5-year survival rate for complete surgical resection of benign tumors was 83.6% ,and that of malignant tumors was 27.3%. After a median follow-up of 36 months (range 5 ～ 168)for the resection of malignant tumors, the local recurrence rate was 53%. Median time between initial surgery and recurrence was 25 months (range 3 ～ 108). For local recurrence of malignant tumor, the complete surgical resection rate was 62.5%. One patient died of intraabdominal hemorrhage in the first day after operation. Conclusion For PRT patients, early diagnosis is often difficult. Preoperative imaging results are essential to predict the surgical resectability. The optimal treatment of patients with PRT is radical resection, an bloc organ resection if necessary. Regularly postoperative follow-up is mandatory for early finding recurrence.

Objective To better understand and manage the current situation and problems of patent transformation in university affiliated hospital.Methods we conducted the statistical analysis the quantity of patent authorization in the Peking University People's Hospital during 2002-2013,and the status of patent transformation.Results The quantity of patent authorization increased significantly,however the number of patent transformation is small,with low proportion.Meantime,the transformation period is long,with single mode.Conclusions the hospital should be strengthened for all patent life-cycle management,and strengthen the emphasis on the conversion work to build integrated management team,in particular by building technological achievements promotion platform,improve the incentive mechanism to strengthen the franchise use of the work.

Objective To investigate the effect of cardiotrophin-1 (CT-1) mediated by recombinant adenovirus (Adv) on the neural differentiation of bone marrow mesenchymal stem cells (rBMSCs) of rats.Methods The rBMSCs were isolated and cultured by attachment method.The surface marker protein was identified by flow cytometry.The rBMSCs were divided into 4 groups:control group,AdV enhanced green fluorescence protein (Adv-EGFP) + induction group(empty virus group),CT-1 group and induction group.The cells were transfected by Adv in the corresponding multiplicity of infections.Each group was induced by neural induction medium except for control group.The cells morphological changes were observed by microscope and the expressions of Nestin,neuronal nuclei (NeuN) and glial fibrillary acidic protein(GFAP) were detected respectively by cellular immunofluorescence at 5 h,3 d and 7 d after induction.Results After induction treatment,neuron-like cells morphological changes were observed in all the groups except for control group,among which the most obvious change was found in CT-1 group.The positive rate of Nestin was the highest at 5 h after induction.Positive rate of CT-1 group[(86.31 ± 4.27)％] was higher than any other groups,the differences were statistically significant (all P ＜ 0.001);after which its positive rate gradually declined,the positive rate of CT-1 group changed more obviously than other groups,and the differences were statistically significant (all P ＜ 0.001).The difference in Nestin positive rate between the empty virus group and induction group was not statistically significant (all P ＞ 0.05) at various time points.The NeuN and GFAP could be observed in CT-1 group at 5 h after induction.Then the positive rate of NeuN and GFAP increased gradually,and climbed to the highest point [(64.41 ± 3.65)％,(47.14 ± 4.29)％] on 7 d after induction.Positive rate of NeuN and GFAP in CT-1 group at various time points were higher than that of other groups,and the differences were statistically significant (all P ＜0.001).The difference of NeuN and GFAP positive rate between the empty virus group and induction group was not statistically significant (all P ＞ 0.05).Conclusion CT-1 could promote the neural differentiation of rBMSCs.

This paper analyzed the system,methods,content,scope and standards of last two competition in order to further improve the clinical skills competition for national medical students in China.According to the characteristics of medical education,the paper proposed several opinions and suggestions as follows:repechage should be cancelled in competition system and objective structured clinical examination should be used in competition; the content,scope and criteria of the competition should take the actual ability of the medical students at graduation into consideration.
