Pancreatic neuroendocrine tumor (pNET)is a rare type of pancreatic tumors.The incidence of pNET shows a gradually increas-ing trend in recent years.The most common organ of distant metastases is the liver.Surgical resection is still the optimal treatment for resect-able,well -differentiated liver metastases with no evidence of extrahepatic spread.For unresectable patients,a combination of multiple mo-dalities,such as transarterial chemoembolization,radiofrequency ablation,systemic chemotherapy,and molecular targeted therapy,can pro-long the survival time of patients.Liver transplantation should be strictly evaluated on an individual basis.

Objective To investigate ulnar impaction syndrome imaging characteristics and wrist arthroscopy in the diagnosis and treatment effects.Methods From September 2006 to April 2014,41 patients with ulnar impaction syndrome were treated.Of all 41 patients,28 were male and 13 female with an average age of 34.5±3.9 years old (ranging from 15 to 52 years old).The preoperative values of wrist range of motion (ROM) were 44.17°±6.22° at volar flexion,42.72°±3.37° at dorsal extension,17.45°±4.11° at radial deviation,19.12°±3.70° at ulnar deviation,66.81°±4.28° at pronation,and 70.27°±5.30° at supination.Arthroscopic exploration was conducted in all patients,aiming to observe the ulnar variance,wrist osteonecrosis,articular cartilage damage and triangular fibrocartilage complex tear.Arthroscopic synovectomy were performed in all cases;33 cases of articular cartilage injury were treated with arthroscopic chondroplasty;16 cases of osteonecrosis were treated with arthroscopic drilling decompression;30 cases with tear of TFC were treated with arthroscopic repair;26 cases with ulna positive mutation were treated with arthroscopic distal ulna resection.Patients were followed at 3,6,and 12 months after operation.At 12 months follow-up,the values of wrist range of motion was evaluated for volar flexion,dorsal extension,radial deviation,ulnar deviation,pronation,and supination.GreenO'Brien method was used to evaluate the function of wrist joint.Results Primary healing was presented in all patients without neurovascular injury and joint infection.All patients were followed up 12-36 months (mean,17.5 months).At 12 months followup,the values of ROM compared with that preoperative increased with significant difference,49.13° ±3.47° at volar flexion,47.13°±2.39° at dorsal extension,19.33°±3.29° at radial deviation,25.17°±4.89° at ulnar deviation,75.73°±7.66° at pronation,and 77.22°±4.89° at supination.According to Green-O'Brien standard,the results were excellent in 21 case,good in 17 cases and fair in 3 case,with 93％ excellent and good rate.Conclusion Wrist arthroscopy dose not only contribute to the diagnosis in ulnar impingement syndrome but also can be used in treating inflammatory synovium and cartilage lesions,bone drilling decompression,TFC repair and arthroscopic distal ulna resection with improvement in the range of motion of the wrist joint and function.

Objective To investigate the relationship of the nutritional status with liver function and clinical outcomes of liver cancer patients treated with surgery.Methods Altogether 112 hospitalized patients undergoing surgical treatments for liver cancer were enrolled from October 2011 to October 2013.Their general clinical data were collected,including creatinine-height index (CHI),arm circumference,grip strenghth,albumin,prealbumin,and transferrin.The nutritional status was assessed using Patient-Generated Subjective Global Assessment (PG-SGA).The liver function was assessed with Child-Pugh classification.Postoperative infectious complications and the hospital stays were recorded to assess the clinical outcomes.The correlation between nutritional status and liver function,and that between nutritional status and clinical outcomes were analyzed.Results Among the 112 patients,70 (62.5％) were in normal nutritional status,34 (30.4％) were with moderate malnutrition,and 8 (7.1％) were with severe malnutrition according to PG-SGA scores.PG-SGA assessment showed strong consistence with CHI nutritional assessment (κ =0.760,P =0.000),and moderate consistence with arm circumference assessment (κ =0.564,P =0.000),and grip strength assessment (κ =0.523,P =0.000).The live function classified by Child-Pugh was found highly correlated with PG-SGA assessment (rs =0.829,P =0.000).Postoperative infectious complications and hospital stays were both positively correlated with PG-SGA assessment (r =0.349,P =0.000 ; r =0.624,P =0.000).Conclusions PD-SGA combining with CHI can be used for the nutritional status assessment of liver cancer patients undergoing surgical treatments.The nutritional status of the patients has positive correlation with live function,infectious complications,and postoperative hospital stays.

Objective To analyze the effect of individualized care on prevention of postoperative urinary retention of malignancy patients undergoing hysterectomy and pelvic lymph node dissection.Methods 74 cases of patients with malignancies undergoing total hysterectomy and pelvic lymph node dissection in our hospital from June 2009 to December 2011 were chosen as the research object.They were divided into the control group and the observation group with 37 cases in each group.The control group was given traditional routine care,while the observation group was given individualized nursing assessment and intervention.The grasping level of knowledge about prevention of urinary retention,the cooperation degree with nursing,incidence of urinary retention,the residual urine volume and satisfaction degree of patients were analyzed and compared between two groups.Results The grasping level of knowledge about prevention of urinary retention,the cooperation degree with nursing,incidence of urinary retention,the residual urine volume and satisfaction degree of patients in the observation group were better than those of the control group,there were significant differences.Conclusions The effect of individualized care to prevent postoperative urinary retention of malignancies patients after hysterectomy and pelvic lymph node dissection is better.It plays an active role in improving mastering of knowledge about prevention of urinary retention and cooperative degree with nursing.

ObjectiveTo explore the effect of problem-based health education on self-care ability and psychological situation of gynecological cancer patients after surgery.Methods68 cases after gynecological cancer from January 2009 to December 2011 in our department for treatment were chosen.By taking mechanical sampling method,45 cases were randomly set as the observation group,which took problem-based health education.Other 23 cases were set as the control group,which adopted general health education model.The effect of health education was compared between two groups.ResultsIn the observation group,the self-care skills score was (20.4±5.8),self-responsibility score(27.6±9.4),the self-concept score (15.7±8.3) and self-care ability score (111.6± 20.3),significant higher than those of the control group,which were (11.6± 4.4 ),( 17.3 ± 6.5 ),(7.4 ± 5.1 ) and (53.2 ± 12.8).The SAS score was (1 1.6 ± 4.4) and SDS score was (17.3± 6.5) in the observation group,significantly lower than (20.4 ± 5.8) and (27.6± 9.4) of the control group.ConclusionsApplication of problem-based health education in gynecological cancer patients can significanfly improve their self-care capacity and patients＇ anxiety and depression.

Purpose:To investigate the effect of replication defective retroviral vectors carried sense or antisense TGF?1 fragment on the cell cycle regulation and proliferation of human bladder cancer. Methods:The replication defective retroviral vectors that integrated sense or antisense bioactive fragment of transforming growth factor?1 were constructed,and named as pRevT? and pRevT?-AS respectively. The influence of each vector on the cell proliferation,clone-formation and alteration of cell cycle of bladder cancer cell line EJ were observed in vitro.Results:The titre of pRevT? and pRevT?-AS were 0.84,0.88?10 5 CFU/ml respectively,the vectors integrated to EJ cells and expressed efficiently. Inhibition TGF?1 gene expression reduced proliferation and clone-formation rates of EJ cells. The G 0 /G 1 stage ratios in the antisense TGF?1-transfected EJ cells were increased,simultaneously,the S stage ratios were decreased. Conclusions:The antisense TGF?1 vector can reduce the expression of endogenous TGF?1 in EJ cells,induce G 1 stage arrest and inhibit proliferative growth in vitro.
