Objective To explore the surgical treatment of the primary retroperitoneal tumor (PRT). Methods A retrospective clinical data analysis was made on the 59 cases of PRT who underwent operation. Results 59 cases were diagnosed by operation and pathologic examination.In 41 cases of malignancyt ( 69.49%),complete resection, partial resection, surgical exploration and biopsy were performed on 15 cases (36.6%), 8 cases (19.5%) and 18 case (43.9%) , respectively. The 3- and 5-year survival rates of maligment PRT with total resection were 53.3% and 26.7%,and with partial resection were 19.23% and 7.69% respectively.In 18 cases of benign tumor (30.5%),complete resection, partial resection, surgical exploration and biopsy were performed on 14 cases (77.8%), 3cases (16.7%) and 1case ( 5.6%) , respectively. The 3- and 5-year survival rates of benign PRT with total resection were 92.86% and 85.7%,and with non-completely resection were 75.0% and 50.0%, respectively. Conclusions Operation is the main treatment of PRT. Early diagnosis and radical resection are the keys in improving the prognosis of PRT.

[Summary] During recent years, increasing evidences have indicated that type 2 diabetes mellitus(T2DM) might increase the risk of certain tumors; the process might be not only related with the chronic pathologic status of T2DM such as hyperglycemia, hyperinsulinemia, insulin resistance, dyslipidemia, status of chronic inflammation but also associated with the long-term use of anti-diabetic drugs (i. e. sulfonylureas, biguanides, glitazones, dipeptidyl peptidase-4 inhibitors, glucagon-like peptitide-1 receptor agonists), as well as the use of insulin and insulin analogues. Herewith a system review was made about the recent progress in studying T2DM and tumor risk.

Objective This retrospective study was to explore the efficacy and determine the risk factors of survival for recurrent hepatocellular carcinoma ( HCC) treated by repeat hepatectomy. Methods From January 1995 till December 2010, 60 patients with recurrent HCCs, were treated by repeat hepatectomy.The significance of seventeen clinical or pathological variables in the risk factors of overall survival were assessed. Results The overall survival 1,3, and 5-year survival rates were 76. 3% , 40.7% and 25. 0% (from repeat hepatectomy), and 95. 0% , 62. 6% and 43. 3% ( from initial hepatectomy) , respectively.Univariate analysis indicated that tumor size at initial hepatectomy, recurrence interval from initial hepatectomy, serum albumin(ALB) level, resection margin, diameter of largest recurrence tumor and rumor vascular invasion were significant prognostic factors(P <0. 05, Kaplan-Meier Log-rank test). Multivariate analysis showed recurrence interval from initial hepatectomy, resection margin, diameter of largest recurrence tumor and rumor vascular invasion were significant prognostic factors(P<0.05, Cox proportional hazards model).Conclusion Repeat hepatectomy is effective for recurrent HCC. Recurrence interval from initial hepatectomy, resection margin, diameter of largest recurrence tumor and rumor vascular invasion were significant prognostic factors.

Objective:To illuminate the influence of InsB15-23 H-2Kd dtSCT to the morbidity of type 1 diabetes mellitus in NOD mice.Methods:An eukaryotic plasmid encoded membrane-expressed InsB15-23 H-2Kd dtSCT was inoculated into 3 weeks old female NOD mice subcutaneously and the blood sugar and morbidity of type 1 diabetes mellitus were monitored once a week.To illuminate the cellular mechanism of immunologic intervention of membrane-expressed InsB15-23 H-2Kd dtSCT to the course of type 1 diabetes mellitus in NOD mice,the mononuclear cell infiltration of islets was detected by tissue slice and the frequency of IGRP206 2-14 specific CTLs in PBMC was analyzed by FACs.Results: As compared with pcDNA3.1 (-) control ( 60%) and untreated NOD mice ( 80%) , mice immunized with InsB15-23 H-2Kd dtSCT exhibited low level of islet infiltration and low morbidity in 30 weeks old ( 9%) .But the frequency of IGRP206-214 specific CTLs in PBMC of 16 and 40 weeks old mice showed no difference.Conclusion:Membrane-expressed InsB15-23 H-2Kd dtSCT can protect NOD mice from type 1 diabetes mellitus in IGRP206-214 independent pattern.

Objective To evaluate the value of urinary normal and modified nucleosides in the diagnosis of primary gallbladder carcinoma.Methods Between March 2011 to September 2012,28 patients with primary carcinoma of the gallbladder (PCG) were included in this study.Spontaneous urine samples were collected and 10 kinds of urinary nucleosides in the sample were determined by reversed-phase high performance liquid chromatography method.Another 62 patients with benign gallbladder disease and 70 healthy volunteers were enrolled as controls.Routine clinical tumor markers,including serum CA19-9 and CA125 levels of the PCG patients were also evaluated.Results 10 kinds of nucleoside had a good linear correlation (r＞0.99),and the recovery rate was between 87.4％ ～121.5％ range,and the accuracy rate was between 87.7％ ～121.3％,and the RSD of precision was between 1.5％～10.5％ range.In addition to adenosine and cytidine,the mean levels of the rest of the urinary nucleosides in the PCG group were much higher than those of the controls (P＜0.01).Based on principal component analysis,89.3％ of the PCG patients were correctly identified,which was much higher than those detected by CA19-9 (60.7％) and CA125 (67.9％) (P＜0.01).Conclusion Urinary nucleosides may become additional tumor markers which when combined with other clinical methods may help in the screening and early diagnosis of primary gallbladder cancer.

Objective To investigate the effect of reinfusion of drained bile and pancreatic juice on the outcome of pancreaticoduodenectomy (PD).Methods The clinical data of 51 patients who received PD at the Affiliated Hospital of Binzhou Medical College from June 2005 to March 2009 were retrospectively analyzed.Nineteen patients received external drainage of bile and pancreatic juice ( ED group) and the other 32 patients received external drainage and intraintestinal administration of autologous bile and pancreatic juice (ID group).The daily volume of output of bile and pancreatic juice,intraoperative condition,tolerance of enteral nutrition,liver function and nutritional parameters of the 2 groups were detected.All data were analyzed by using chi-square test,Fisher exact test,independent t test,Mann-Whitney U test and one-way analysis of variance.Results The pulmonary infection rate of ID group was 3％ (1/32) after operation,which was significantly lower than 26％ (5/19) of the ED group (P ＜ 0.05).The output of pancreatic juice in the ID group was significantly lower than that in the ED group since postoperative day 4 ( t =7.143,9.244,8.808,7.915,6.461,14.097,15.038,P ＜ 0.05 ).There was no significant difference in the daily output of bile between the 2 groups.The incidence of diarrhea in the ID group was 9％ (3/32) after nutritional support,which was significantly lower than 37％ (7/19) of ED group (P＜0.05).The duration of achieving targeted enteral feeding in the ID was 3 days,which was significantly shorter than 4 days of the ED group ( U =145.000,P ＜ 0.05 ).The levels of total bilirubin ( TBil),direct bilirubin (DBil) and indirect bilirubin (IBil) were (261 ± 108 ),( 132 + 55 ) and ( 129 + 55 ) μmol/L in the ID group,and (239 ±92),( 12A ±46) and ( 116 ±46) μmol/L in the ED group before operation.The levels of TBil,DBil and IBil were (39 ± 19),(20 ± 10) and ( 19 +9) μmol/L in the ID group,and (55 ±22),(29 ± 12) and (26 ±11 ) μmol/L in the ED group at 12 days after nutritional support.There were significant differences in the decrease of TBil,DBil and IBil between the 2 groups ( t =7.324,8.437,5.827,P ＜ 0.05 ).The levels of serum prealbumin,retinol binding protein and transferrin were (0.261 ± 0.021 ) g/L,(34.3 ± 2.8 ) mg/L,(3.08 + 0.26 ) g/L in the ID group,and (0.263 ±0.021)g/L,(33.8 +3.5)mg/L and (3.10 +0.27)g/L in the ED group before operation.The levels of serum prealbumin,retinol binding protein and transferrin decreased significantly after operation,and then got increased 3 days after nutritional support.The levels of serum albumin,retinol binding protein and transferrin were (0.238 ±0.025)g/L,(30.7 ±2.0)mg/L,(2.78 ±0.19)g/L in the ID group,and (0.222 +0.025)g/L,(29.3 ±2.1)mg/L and (2.63 +0.21)g/L in the ED group at 12 days after nutritional support.The levels of serum albumin,retinol binding protein and transferrin in the ID group were significantly higher than those in the ED group (t=4.615,6.097,4.913,P＜0.05).Conclusion Reinfusion of external drained bile and pancreatic juice after PD could enhance the tolerance of patients in early enteral nutrition,reduce incidence of pneumonia,promote decrease of serum bilirubin and improve the nutritional status.

Objective To analyze the incidence of BK virus (BKV) infection after kidney transplantation in our center and to evaluate the efficacy and safety of conversion treatment with Mizoribine (MZR) on BKV infection after kidney transplantation.Methods The information of recipients who received BK virus screening in hospital or outpatient during 2015-02 to 2016-12 in our center was retrospectively analyzed.The recipients positive for BKV were divided into experiment group (given conversion treatment with MZR) and control group (not given MZR conversion) according to the inclusion criteria.The negative rate of BKV,AR,hyperuricemia and the function of renal allograft during the conversion treatment with MZR were observed.Results 182 recipients accepted BKV screening during 2015-02 to 2016-12 and 68 cases were positive.The positive rate of BKV was 38.5 ％.The positive rate of peripheral blood specimens and midstream urine specimens was 7.1％ and 36.8％ respectively.Twelve recipients were positive for BKV in both peripheral blood specimens and midstream urine specimens.There were 27 recipients in experiment group and 36 cases in control group.Fourteen recipients positive for BKV became negative after MZR conversion in experiment group and the negative rate was up to 51.9％.The mean time of negative rate was 3.2 ± 2.7 (1-10) months after MZR conversion.During the conversion treatment with MZR,AR occurred in 1 case and was reversed by the impact therapy with Thymoglobulin in experiment group.The value of serum uric acid was maintained stable before and after MZR conversion under the action of uric-acidlowering drug.The renal function was kept stable in both experiment group and control group after renal transplantation.No deaths and renal allograft failure cases occurred in both groups during the research period.The 2-year survival rate for patients and kidneys was both 100％.Conclusion The incidence of BKV infection after kidney transplantation was high and the treatment scheme of MZR conversion was safe and effective.
