Objective To summarize the etiology,classification and clinical characteristics of congenital bile duct dilatation and our experience in its diagnosis and troatment.Methods The clinical data of 37 cases of congenital bile duct dilatation were retrospectively analyzed.Results The 37 cases included TypeⅠin 31 cases,Type Ⅱ in 1 case,Type Ⅳ in 4 cases,and Type Ⅴ in 1case.All of the patients underwent operative treatment.External drainage of was done in 2 cases,Roux-en-y cystojejunostomy in 3 cases,exeisison of cyst cyst and Roux-en-y hepaticojejunostomy in 31 cases and left hepatectomy in 1case with malignant change of cyst.Five cases had postoperative complications that recovered with non-operative treatment.Thirty-two cases were cured.There were no operative deaths.Conclusions Congenital bile duct dilatation should be treated as soon as possible.Excision of the cyst and Roux-en-y hepaticojejunostomy can reduce long-term postoperative complications and is the rational treatment for congenital bile duct dilatation.

Sixty-six volunteers,including 24 subjects with normal glucose tolerance(NGT),18 patients with impaired glucose regulation (IGR),and 24 patients with type 2 diabetes mellitus ( T2DM ),underwent a test of continuous glucose monitoring.The data of continuous glucose monitoring were embedded into two-dimension Euclid space by Takens' embedding theory.Glycemic phase diagram was drawn by MATLAB.The area and center distance of glycemic phase diagram were calculated by computer.The distinction of glycemic variability and average glycemic level among different glucose regulation populations were analyzed.The results showed that there existed significant differences in body mass index,systolic blood pressure,diastolic blood pressure,low density lipoprotein-cholesterol,high density lipoprotein-cholesterol,triglyceride,total cholesterol,creatinine,and alanine aminotransferase among three groups( all P＜0.05 ).The levels of HbAIC,fasting plasma glucose( FPG ),postprandial 2 h plasma glucse (2hPG),area and center distance of glycemic phase diagram in T2DM group were higher than those in NGT and IGR groups( P＜0.01 ),and the levels of FPG,2hPG,area and center distance of glycemic phase diagram in IGR group were higher than those in NGT group( P＜0.01 ).The levels of FPG and 2hPG were correlated with area and center distance of glycemic phase diagram ( all P＜0.01 ).These results suggest that measuring the area and center distance of glycemic phase diagram is a good method to assess glycemic variability and average glycemic level during continuous glucose monitoring.

Objective To observe changes of luteinizing hormone (LH), follicle-stimulating hormone (FSH) and testosterone (T) in umbilical vein blood between male and female neonates, and assess the effect of serum LH, FSH and T on fetal growth.Methods Umbilical vein blood was obtained from 130 neonates (64 females and 66 males) in the second hospital of changshu city. According to birth weight, 130 neonates were divided into 3 groups: macrosomia (n=28), intrauterine growth restriction (IUGR) (n=31) and normal neonates (n=71). The serum levels of LH, FSH and T were measured by radioimmunoassay.Results 1.The levels of LH, FSH and T in umbilical vein blood were significantly higher in male neonates than those in females (P

Objective To evaluate myocardial apoptosis with 99Tcm-C2A-GST myocardial imaging using the recombined C2A domain of Synaptotagmin Ⅰ by gene engineering. Methods ( 1 ) The C2A gene was inserted into the prokaryotic glutathione S-transferate (GST) fusion protein expression plasmid pGEX-6P-1. The recombinant plasmid was transformed into E. coli BL21. C2A-GST fusion protein was purified after BL21 was induced with isopropyl-β-D-1-thiogalactopyranoside (IPTG). (2)The activity of fusion protein was identified by cell binding test with fluorescein-5-isothiocyanate (FITC)-C2A-GST. (3) The C2A-GST fusion protein was labeled with 99Tcm using 2-iminothiophene hydrocoride method. Radiochemical purity was determined with thin layer chromatography. (4)99Tcm-C2A-GST (7.4 MBq) was injected to ischemia-reperfusion rat models through tail vein. The image was acquired with SPECT at 1 h after injection, and then hearts were removed, rinsed with saline and dyed with triphenyl tetrazolium coride (TTC). The ischemic myocardium was separated from the viable myocardium and was weighted. Its radioactivity was measured by gamma counting. The difference of uptake of radiotracer between ischemic myocardium and normal myocardium was compared using percentage activity of injected dose per gram of tissue ( % ID/g) with standard deviation. SPSS 12.0 and t-test were used for data analysis. Results ( 1 ) C2A-GST fusion protein wassuccessfully expressed and its relative molecular weight was 3.8 × 104. (2) FITC-C2A-GST binding to apoptotic cells could be observed by fluorescent microscopy. (3) The radiochemical purity of 99Tcm-C2A-GST was (98.90 ±0.43)%. (4)The imaging studies showed that there was focal uptake of radioactivity in the ischemic myocardium. In vitro uptake of 99Tcm-C2A-GST was (2.41 ±0.32) % ID/g by the ischemic myocardium, however 99Tcm-C2A-GST-N-hydroxysuccinimide (C2A-GST-NHS) was (0. 82 ± 0. 24) % ID/g. There was statistically significant difference between those two groups (t = 10. 6, P ＜0.01 ). Conclusion The C2A domain of Synaptotagmin Ⅰ expressed by gene engineering can be used as the tracer for noninvasive detection of ischemic myocardium in the ischemia-reperfusion rat model.

Objective This is the first study to explore clinical application value of serum Dickkopf-1 (DKK-1) detection in diagnosis of heptocellular carcinoma (HCC) by magnetic solid phase chemiluminescent immunoassay.Methods The level of serum DKK-1 and AFP in 205 cases of HCC,40 cases of liver cirrhosis,and 200 cases of healthy control were quantitatively detected by Magnetic solid phase chemiluminescent immunoassay.The area under ROC curve,sensitivity and specificity of DKK-1 and AFP for diagnosing HCC were calculated.Results The serum level of DKK-1 in HCC group was significantly higher than those of the liver cirrhosis group and healthy control group (P<0.01).DKK-1 maintained diagnostic sensitivity for patients with HCC who were alpha-fetoprotein (AFP) negative (66.3%).ROC curves showed optimum diagnostic cut-off value was 2.4 ng/mL,area under curve (AUC) was 0.822 (95% CI:0.783-0.856),sensitivity 65.9%,and specificity 87.5%).Moreover,measurement of DKK1 and AFP together improved diagnostic accuracy for HCC versus all controls compared with either test alone [AUC 0.915,95%CI:0.886-0.940),sensitivity 81.5 %(P<0.05)].Conclusion Serum DKK-1 detection has an important clinical value for diagnosis of HCC,especially for HCC with AFP negative.The combined detection of serum DKK-1 and AFP can greatly increase sensitivity and accuracy for diagnosing HCC.

Objective To study the expression of plasma membrane Ca2 + -ATPase isoforms 1 -4 and the splice variants at sites A and C in the neonatal rat vestibular organ.Methods Ten rats at postnatal 2 days (P2 ) were decapitated and their vestibular organs (macula utriculi and macula sacculi)were isolated.The total proteins of the vestibular organs were extracted.The expression of PMCA1-4 splice variants at sites A and C was detected by RT-PCR.Results The splice variants of PMCA1-4 at sites A and C in macula utriculi and macula sacculi of neo-natal rat vestibular organs were PMCA1x/b,PMCA2w/(a,b),PMCA3z/(a,b,c)and PMCA4 (x,z)/b.Conclusion The splice variants at sites A and C among PMCA1,PMCA2,PMCA3 and PMCA4 were different in the vestibu-lar organs of neonatal rats,which could be explained that macula utriculi and macula sacculi had different require-ments of Ca2 + turning for these PMCA isoforms.
