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.

This paper discussed multiple teaching methods used in classroom instruction which are used for Medicianl Chemistry Education of Preclinical Medicine Graduate Students,which were proved to be effective.

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 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.

Numerous studies showed that changes in serum pepsinogen( PG)and gastrin-17( G-17)levels can reflect histological condition of gastric mucosa,that can be served as serological biopsy of gastric fundic glandular mucosa. The decrease of serum PGⅠ level and PGⅠ/ PGⅡ ratio(PGR)as well as increase of G-17 denotes a high risk of gastric cancer. Helicobacter pylori(Hp)infection can cause chronic active gastritis,and the progress of inflammation can lead to atrophy and intestinal metaplasia of mucosa. This article reviewed the diagnostic value of serum PG,G-17 and Hp antibody for atrophic gastritis and gastric cancer.

Gestational hyperlipidemic pancreatitis is an uncommon complication of pregnancy that incurs a high risk of morbidity and mortality of both maternal and fetal patients.We described the response of continous renal replacement therapy in a woman with extreme gestational hyperlipidemia and severe pancreatitis.Five consecutive plasma exchanges didn't lead to a remarkable reduction(10.4% and 4.8%,for the first and fourth times,respectively) at triglyceride levels as the literatures have reported,which reveals that plasma exchange and continous veno-venous heamofiltration may be importment,instead of crucial methods in dealing with gestational hyperlipidemic pancreatitis.Abstract:SUMM ARY Gestational hyperlipidem ic pancreatitis is an uncommon complication of pregnancy that in-curs a high risk ofmorbid ity and mortality of both maternal and fetal patients.W e described the response of continous renal replacement therapy in a woman with extreme gestational hyperlipidem ia and severe pancreatitis.Five consecutive plasma exchanges d idn’t lead to a remarkable reduction(10.4% and 4.8%,for the first and fourth times,respectively) at triglyceride levels as the literatures have reported,which reveals that plasma exchange and continous veno-venous heamofiltration may be importment,in-stead of crucialmethods in dealing with gestational hyperlipidem ic pancreatitis.

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.

Objective To determine the main predictors of circulatory crisis after replantation in patients with severed distal finger so as to establish the theoretic basis in reducing the morbidity of circulatory crisis. Methods 65 severed distal fingers underwent replantation were respectively reviewed. All the clinical parameters including age, sex, dominant hand or finger, preservation of the severed finger, platelet level, ischemia duration, cause of injury, manner of venous drainage, repair of artery, order of reparation and plane of division were investigated as predictive risk factors for circulatory crisis of finger after replantation. In order to find the risk factors of circulatory crisis, the data was dealt with t test, ?2 test, analysis for variance or multivariate Logistic regression analysis. Results 13 replanted finger suffered from impaired circulation in 65 fingers. Univariate analysis demonstrated that many factors were significantly correlated with the circulatory crisis of finger, such as the manner of venous drainage(?2=6.714,P=0.035), the cause of injury (?2=9.049,P=0.011), the preservation of severed finger(?2=6.452,P=0.040), the age(?2=14.838,P=0.001), the platelet level(uc= 2.961, P=0.003). The multivariate Logistic regression analyses showed that platelet level (OR=1.015, P=0.030), the age(OR=0.349, P=0.031) and the manner of venous drainage(OR=0.278,P=0.036) were the significant independent predictors for circulatory crisis. The incidence of circulatory crisis in patients less than 6 years old was 61.5%, significantly higher than any other age group(P

0.05 . In combined test, the combined OR= 3.164 , OR = 3.209 and its 95% confidence interval was in 1.390 ～ 7.200 and 1.747 ～ 5.900 , respectively. CONCLUSION: The case fatality rates in combination group were significantly lower than those in single somatostain group. The efficacy of combination group was superior to that of single somatostain group.
