Objective To evaluate the diagnostic value of intraductal ulstrasonography(IDUS)in non-opaque bile duct stones.Methods Between January 2009 and August 2010 in the Department of Gastroenterology at Shanghai 10th People's Hospital,a total of 183 patients(male:102 cases,mean age 69 years； female:81 cases,mean age 71 years)were enrolled,who were suspected of bile duct stones or stenosis which could not be diagnosed by abdominal CT,MRI,and abdominal B-mode ultrasound.All the patients underwent endoscopic retrograde cholangiopancreatography(ERCP)first,and then patients with non-opaque bile duct stones followed by IDUS.Results A total of 134 cases (73.2％)of bile duct stones were diagnosed by ERCP,49 cases(26.8％)were negative.And then the 49 patients underwent IDUS,of whom 24 patients with sand-like stones,11 patients with lowdensity stones,6 patients with ampullary cancer,2 patients with pancreatic cancer,6 patients with sclerosing cholangitis.The diagnostic accuracy of IDUS in the position and quality of bile duct stones was 100％,higher than that of ERCP,which was 80％.After ERCP,pancreatitis occurred in 3 patients and improved after conservative treatment,there was no complications like perforation and bleeding.Conclusion The diagnostic accuracy of IDUS in the position and quality of bile duct stones is high,which can make up for the misdiagnosis by ERCP without increasing the complications.IDUS can provide reliable basis for the diagnosis of clinical bile duct stones.

Objective To synthesize glycylproline p-nitroanilide tosylate as a substrate for glycylprolyl dipeptidyl-aminopeptidase(GPDA),and to study its clinical application.Methods The title compound was prepared by DCC-HOBt synthesis.GPDA in human serum was detected by continuous monitoring method using substrate. Results The substrate with purity of 98.5% was obtained.The linearity of the method was up to 358.1 U/L.Intraassay CV and interassay CV of GPDA in diverse serum samples were 3.01% and 5.04%,respectively.It was shown that GPDA level in patients with hepatic cancer was significantly increased,while those in patients with gastric carcinoma and chronic gastritis were significantly decreased compared with that in the control group in clinical detecting(P

ObjectiveTo study the effects of aqueous extract of Trigonella foenum-graecum(AET) on the blood glucose in normal and alloxan(ALX)-diabetic mice.MethodsFasting blood glucose and glucose tolerance in normal and ALX-diabetic mice were measured respectively 7 days after AET had been given.ResultsAET had not significantly effected the fasting blood glucose of normal mice, but improved their glucose toleranc. Otherwise, AET reduced fasting blood glouse of diabetic mice induced by ALX significantly.ConclusionAET can be used on treatment of diabetes mellitus.

ObjectiveTo explore the influence of electrical stimulation on nervous cells.MethodsOn 5th day the brain primitive nervous cells of rat brain, in vitro culturing, were divided into 4 groups, in order of control group, electrical pole control group, low stimulation group, and high stimulation group. The cells were stimulated with electro-acupuncture apparatus for 7 days, 30 minutes once, twice a day. On 10th day, the cells were observed microscopically for 3 days and taken photos.ResultsElectrical stimulation is helpful to raise the survival rate of cell.Conclusions Electrical stimulation influences morphological change of nervous cells during culturing.

Objective To investigate the significance and distribution of lymphopenia and antilymphocyte antibody(ALA) in systemic lupus erythematosus (SLE) and to explore the role of ALA in lympho penia.Methods One hundred and ten in-patients who were admitted during February 2003 to February 2008 were retrospectively reviewed.Indirect immunofluorescence test was used to detect ALA.Results ① Lymphopenia (＜1.5×109/L) was observed in 68.2% patients.Lymphopenia was associated with skin rashes,serositis,renal involvement,NPSLE,leucopenia,ANA,ds-DNA antibody,ESR and IgG levels.The lymphocyte count and SLEDAI scores was more closely correlated than total white blood cell counts.②ALA was positive in 51/110 (46.4%) patients.ALA was associated with renal involvement,NPSLE,WBC count,C3 level decrease,ANA,dsDNA antibody and SLEDAI scores.Conclusion Lymphopenia is significantly associated with SLEDAI scores.ALA is possibly one cause of lymphcytopenia.In addition,ALA is also a parameter for disease activity,and is associated with organ involvement and outcomes.

Objective:To explore and test a caregiving experience model by Structural Equation Modeling (SEM)in the family caregivers caring for people with dementia in China. Method:Totally 349 elder patients with dementia and their family caregivers were selected and interviewed,using a battery of measures including demo-graphic data of the dyads,impairement of care recipient,caregiver's appraisal of role strain,role gain,negative and positive well-being outcomes. By using the Kramer's caregiver adaptation model as theoretical framework,a care-giving experience model were hypothesized tested by structural equation modeling (SEM). Result:A five-factor model for the caregiving experience was supported by SEM. The model demonstrated that the severity of dementia significantly influenced the caregiver's appraisal of role strain (β=0. 5 1 ,P<0. 05 ),which predicted indirectly neg-ative well-being outcomes of the caregiver (β=0. 63,P<0. 05). On the other hand the caregiver's appraisal of rolegain which was negatively influenced by the severity of parent's dementia (β=-0. 33,P<0. 05),predicted posi-tive well-being outcomes of the caregiver (β=0. 75 ,P<0. 05 ). Conclusion:It suggests that both positive and nega-tive aspects of caregiving experiences could independently impact on the well-being outcomes of adult-child care-givers,and therefore both aspects should be targeted in supportive interventions for family caregivers in China.
