Objective To explore the clinical value of renal dynamic imaging and urinary N-acetyl-?-D-glucosaminidase(NAG),apoptosis DNA fragment(ADF) in evaluating the damage degree of hydronephrotic kidneys(HnK) in children with hydronephrosis.Methods Level of glomerular filtration rate(GFR) was detected in 41 children with congenital hydronephrosis by renal dynamic imaging,and urine NAG,ADF in pelvis in HnK and healthy kidneys (as controls) were detected by enzyme-linked immuno-sorbent assay(ELISA).Patholo-gic changes of HnK in 41 children were graded intoⅠ~Ⅴ according to Elder standard. And GFR,urinary NAG and ADF of HnK were divi-ded into subgroup according to pathologic changes ,at the same time statistical analysis was performed within each groups. And the correlations of pathologic grades with GFR,urinary NAG and ADF of HnK were analyzed.Results 1.Kindneys GFR in healthy kidneys and Hnk were (174.33?20.43)?10-3 L/min,(143.86?17.51)?10-3 L/min respectinely,and there was significant difference between healthy kidneys and Hnk (P0.05).3.There was significant negative correlation between GFR levels of HnK and pathologic grades(r=-0.814 P0.05).Conclusions For hydronephrotic kidneys,urinary NAG can eva-luate impaired nephric tubule whereas renal dynamic imaging may evaluate the damage level of glomeruli;urine ADF may not indicate the damage level of diseased kidneys in children with congenital hydronephrosis.

Abstract: Objective　This paper aims to explore the effect of live attenuated varicella vaccine on the sensitivity of tuberculin skin test(TST), and to provide reference for tuberculin skin test in the future. Methods　TST and emergency varicella vaccine were administered to students in grade one of a high school in Wuxi, Jiangsu province, who had both TB and varicella cases. Independent-samples t test was used to analyze the mean diameter of induration of TST in day 0, day 83 and day 195. The retrospective cohort study was used to analyze the effect of live attenuated varicella vaccine on TST. 　　Results　The mean induration diameter of 45 students who participated in three TST tests on day 0, day 83 and day 195 were analyzed by independent sample t test. On day 0, there was a difference in the mean diameter of TST induration between the unvaccinated and vaccinated groups(1.630±2.837 vs 5.818±4.530) (t=-3.692, P=0.001). On day 83, there was no difference in the mean diameter of TST induration between the two groups(0.001±0.001 vs 0.114±0.533) (t=-1.000, P=0.329). On day 195, there was a difference in the mean diameter of TST induration between the two groups(1.913±3.774 vs 5.023±5.126) (t=-2.309, P=0.026). Moreover, the retrospective cohort study showed that the mean diameter of TST induration changed more significantly after inoculation with varicella vaccine, RR=6.071, 95%CI (1.667-22.116), P<0.05; After inoculation with varicella vaccine, the mean diameter of TST test did not change significantly from day 0 to day 195 with no statistical significance RR=3.474, 95%CI (0.333-36.240), P>0.05. Conclusions　Live attenuated varicella vaccine may temporarily affect the sensitivity of tuberculin skin test.

OBJECTIVETo examine the differentiation of 5-azacytidine-induced bone marrow stromal stem cells (BMSCs) into cardiomyocyte-like cells and hepatocyte growth factor (HGF) gene expression after HGF gene transfection.

METHODS5-azacytidine was used to induce beagle dog BMSCs to differentiate into cardiomyocyte-like cells. Morphological observation and immunohistochemistry were performed to detect the expression of the markers of cardiomyocyte-like cells including beta-myosin heavy chain (beta-MHC) and alpha-sarcomeric actin. The cells were then transfected with Ad-HGF, and the mRNA and protein expressions of HGF gene were detected by RT-PCR and ELISA, respectively.

RESULTSAfter 4 weeks of induction with 5-azacytidine, the BMSCs differentiated into cardiomyocyte-like cells. The expressions of HGF at the mRNA and protein levels were confirmed in the cells after transfection with Ad-HGF. The peak HGF protein secretion was 10(3) ng/ml at 48 h after transfection.

CONCLUSIONAd-HGF can efficiently transfect BMSCs induced with 5-azacytidine, and this result provides basic experimental evidence for biotherapy of ischemic heart disease using BMSCs.

Aim To investigate the role of P2X7 recep-tor and its mediated NLRP3 inflammatory signaling pathway in alcohol-induced liver injury. Methods The acute alcoholic liver injury model was established by NIAAA method, and thirty C57BL/6 male mice were randomly divided into three groups (n =10):control group, model group, A438079 group, The three groups were processed as follows in the last week:control group and model group: given an equal dose of saline intraperitoneal injection(about 0.2 mL/only) once a day. According to the weight of the mice, A438079 group was given intraperitoneally injection by 200 μmol·kg-1of A-438079 (prepared at 7 g·L-1 of A438079,about 0.2 mL/only) once a day. And it was given a single 31.5% alcohol solution by intragas-tric administration on the last day of the morning,with the dose of 10 mL·kg-1. Nine hours later alanine aminotransferase (ALT), aspartate aminotransferase (AST),cholesterol(TCHO),triglyceride(TG) were measured by orbital blood in mice. HE staining was used to observe the pathological changes of the liver. Immunohistochemical method was applied to detect the expression of P2X7R in liver tissues. Western blot was employed to detect the levels of P2X7R, NLRP3, ASC, IL-1β and IL-18 in liver tissues. Results Compared with control group,the levels of ALT,AST, TG and TCHO in model group were significantly en-hanced, and the liver injury was obvious. Compared with model group, the levels of ALT, AST, TG and TCHO in A438079 group significantly decreased. Compared with control group, the expressions of P2X7, NLRP3, ASC, IL-1β, IL-18 in model group were significantly higher than those in control group. Compared with model group, the expression levels of P2X7, NLRP3, ASC, IL-1β and IL-18 in A438079 group significantly decreased. Conclusion Alcohol-induced liver injury may be associated with P2X7R-NLRP3 signaling pathway.

The prevalence and genotype of Toxoplasma gondii infection in dogs in Henan Province, Central China was investigated. A total of 125 blood samples were collected from pet dogs during April to June 2013, and all samples were examined by indirect hemagglutination antibody test (IHA) and nested PCR. The overall T. gondii prevalence in pet dogs was 24.0% (30/125), with 20.8% (26/125) in IHA and 10.4% (13/125) in PCR, respectively. No statistical associations were found between animal gender and age and the prevalence of T. gondii infection. Thirteen positive DNA samples were genotyped using 11 PCR-RFLP markers, including SAG1, (3'+5') SAG2, alt.SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1, and Apico. Of these, only 2 samples were genotyped with complete data for all loci, and a novel genotype (type III at SAG3 and GRA6 loci, and type I at other loci) was identified. This is the first report of genetic characterization of T. gondii infection in dogs in China.

OBJECTIVETo explore the value of ultrasono-portography using SonoVue in selective portal vein embolization (SPVE).

METHODSTwenty-eight patients with malignant liver tumors underwent percutaneous ultrasound-guided SPVE. The procedure was performed under color Doppler ultrasound guidance in 11 cases (conventional group) and under guidance with ultrasono-portography using SonoVue in 17 cases (contrast group). Contrast-enhanced CT was performed 2-4 weeks after SPVE to evaluate the effect of embolization.

RESULTSThe procedure of SPVE was aborted in 3 cases in which ultrasono-portography showed contraindications. Postoperative contrast-enhanced CT showed ectopic embolization in 2 cases in the conventional group, and none of the cases in the contrast group showed ectopic embolization.

CONCLUSIONUltrasono-portography using SonoVue can provide important assistance for SPVE.
