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 To study the expression of plasma membrane Ca2+-ATPase isoforms 1~3 (PMCA 1~3 )in the basilar membrane (BM)of the neonatal rat cochlea by Western blot.The PMCA2 content in single BM of the neonatal rat was also examined.Methods Four rats at postnatal 2 days (P2)and 8 days (P8)were respective-ly decapitated and their BMs were isolated.The total proteins of BMs were extracted.The 20μg total proteins were respectively loaded to the gel.The expression of PMCA1-3 was detected by Western blot.Likewise,3μg total proteins from P2 and P8 rat BM were loaded.The expression of PMCA2 was detected by Western blot.Four rats at P8 were decapitated and their BM was isolated.The 5μg,10μg and 20μg total proteins of P8 rat BM were added to the gel and 100 ng,400 ng and 800 ng bovine serum albumin (BSA)were also loaded as reference.After electro-phoresis,the gel was separated into two parts.One part was used for SYPRO staining and the other part was used for PMCA2 detection by Western blot.Results In the 20μg BM total proteins of P2 and P8 rats,the expression of PMCA1 was weak (0.126±0.024,0.131±0.012,respectively),PMCA2 was strong (4.16±0.528,4.25±0.319, respectively),and PMCA3 was barely expressed (0 ).There was a statistical difference among PMCA1 ,PMCA2 and PMCA3(P<0.05).In the 3μg BM total proteins of P2 and P8 rats,the expression of PMCA2 in P8 (4.571± 0.336)was higher than P2 (3.622±0.285).There was a statistical difference(P<0.05).The PMCA2 content in the BM of a P8 rat was about 2 .5 ng.Conclusion There was a different-level expression of PMCA1~3 in the neonatal rat BM with highest expression of PMCA2 ,which could be explained that cochlear hair cells had different requirements of Ca2+ turning for these PMCA isoforms.

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.

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.

The inhibitory ratio (1%) of artificial musk on cyclooxygenase-2 (COX-2) was determined by enzyme immunoassay (EIA). The dose-effect relationship between concentrations of artificial musk and 1% was established. It was found that artificial musk had obvious inhibitory action on COX-2. The concentration for 50% of maximum inhibitory effect (IC50) was about 2.26 mg x mL(-1). There was a good relationship between the logarithm concentrations of artificial musk and 1% when the concentrations of artificial musk ranged from 0.31-20.0 mg x mL(-1). The results indicated that this EIA method could be applied to evaluate the anti-inflammatory activity of artificial musk quickly, conveniently, sensitively and exactly. This paper provided a novel method and foundational research for the bioassay of artificial musk.
