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.

To purify recombinant human nucleoside diphosphate kinase A (rhNDPK-A) efficiently in pilot scale, cells of rhNDPK-A producing E. coli were homogenized by high pressure under 4 degrees C, 950 Pa. The insoluble debris was removed by microfiltration and the soluble portion was concentrated by ultrafiltration. The resulted crude sample was loaded on DEAE-sepharose Fast Flow. The target fraction was collected and then load on Cibacron Blue 3GA Sepharose CL-4B. Eluted with buffer containing ATP from the AC column, rhNDPK-A was polished with ultrafiltration. The results showed that after homogenized 2 rounds, 1500g cells of E. coli brought crude sample containing 47.6g NDPK-A. Treated with microfiltration and ultrafiltration, 27.3g of NDPK-A were recovered from this bacteria homogenate. After 2-step purification with column chromatography and then polished with ultrafiltration, 17.2 g rhNDPK-A were collected with purity of 96.3%. The recovery of the whole purification process was 36.2%, and the productivity of rhNDPK-A was 1.15 g per 100 g wet cells. Comparing the recovery of each purification step, it was found that the recovery of polish is higher than that of affinity chromatography, which is higher than that of ion exchange chromatography. The limit step was the process of sample pretreatment among the 4 purification steps. Combine with the fermentation results reported before, it was deduced that the productivity of rhNDPK-A was 510 mg/L. In conclusion, an easily controlled purification condition with high yield provides material for the translation researches of NDPK; In addition, it was suggested the crucial step determine the recovery of non-secretive recombinant proteins might be the process of sample pretreatment, not be the process of column chromatography.
