The copy numbers of exogenous gene in transgenic animals is always regarded as an important information of transgenic animals.Thus,simple and sensitive methods are required for the detection of the copy numbers of exogenous gene.Three kinds of transgenic Shanbei white cashmere goats,containing Tβ4-GFP,FGF5s-GFP and VEGF164-GFP,has been obtained by using PiggyBac(PB) transposon system.Fluorescence quantitative PCR was carried out to detect the copy numbers of copGFP.Using Gluc as reference gene,the double standard curves of exogenous gene and reference gene were mapped and the genomic DNA of transgenic goats were analysized by real-time fluorescence quantitative PCR.Moreover,the copGFP/Gluc ratio in the samples was calculated as the copy numbers of copGFP.In addition,Tβ4-GFP transgenic cashmere goats were selected to detect the integration sites by using the genomic walking kit.The results showed that the standard curve equation of copGFP was y=-3.230 6x+39.216 (R2 =0.998 8) and the standard curve equation of Gluc was y=-3.564 8x+38.440 (R2 =0.996 0).The copy numbers of exogenous gene in the transgenic cashmere goats were obtained and the numbers of integration sites in the selected Tβ4-GFP transgenic goats were consistent with the copy numbers of copGFP.As a conclusion,the high throughput,fast and sensitive real-time fluorescence quantitative PCR is an efficient and convenient method for the copy number of exogenous gene in transgenic cashmere goats.

The role of interleukin-17 (IL-17) in autoimmune hepatitis (AIH) was investigated. A mouse model of experimental autoimmune hepatitis was established, and the syngeneic S-100 antigen emulsified in complete Freud's adjuvant was injected intraperitoneally into adult male C57BL/6 mice. The IL-17 expression in serum and the livers of the mice models was detected by using ELISA and immunohistochemistry, respectively. IL-17 neutralizing antibody was used to study the biological effect of IL-17 in the experimental AIH. IL-17 neutralizing antibody in vivo administration alleviated the hepatic inflammation and ALT level in the AIH model. IL-17 in the peripheral blood mononuclear cells (PBMC) of AIH patients was measured by using real-time PCR method. The results showed that IL-17 level was significantly up-regulated in AIH patients and mice models. It was concluded that IL-17 contributed to the development of AIH and might be a potential therapeutic target of AIH.

Differential gene expression profiles in Balb/cJ mouse model of acute hepatic failure infected with MHV-3 virus intervened by anti-hepatic failure compound (AHFC) and the changes of cytokines regulated by genes were investigated. The Balb/cj mice were divided into AHFC-intervened group and control group randomly. Acute hepatic failure model of Balb/cJ mice infected with MHV-3 virus was established. The survival rate in the two groups was observed. It was found that the survival rate in the AHFC-intervened group and control group was 90% and 50% respectively 48 h after intraperitoneal injection of MHV-3 (P<0.05). Before and after the experiment, the cytokines in peripheral blood of the survival mice were determined, and RNA was extracted from survival mouse liver tissue for the analysis of the differential gene expression by a 36 kb mouse oligonucleotide DNA array. In all the genes of microarray there were 332 genes expressed differently in the two groups, in which 234 genes were up-regulated and 78 genes down-regulated. Through clustering analysis, the differential expression of immune related genes, including TNF receptor superfamily, Kctd9, Bcl-2, Fgl2, IL-8, IL-6, IFN-gamma, TNF-alpha etc. might be related with the curative effectiveness of AHFC. It was suggested that AHFC can balance the immune state of mouse model of acute hepatic failure infected with MHV-3 virus mainly through regulating the expression of immune related genes, decrease the immune damage and inhibit liver cell apoptosis of mouse acute hepatic failure model obviously so as to increase the survival rate of mouse models of acute hepatic failure.

Objective To investigate the protective effects of FUZHENGJIEDU,a kind of Chinese herb on rats exposed to radon and it's daughter.Methods Twelve male SD rats were exposed with concentration of 40 000 Bq/m3 radon and the exposed dose was 120 work level month (120 WLM),and then all the rats were randomly divided into 2 groups.One group was 120 WLM group (positive control,n=6 ),the other group was FUZHENGJIEDU treatment group (120 WLM exposed rats were given FUZHENGJIEDU 5.0 g every day,n =6),meanwhile 6 rats which lived in the normal environment ( the concentration of radon and it's daughter was lower than 50 Bq/m3 ) as control group.The levels of tumor markers induding carcinoembryonic antigen ( CEA),neuron-specific enolase (NSE),CYFRA21-1 and p53 antibody were tested by ELISA.The rate of p16 gene methylation was measured by methylation-specific PCR (MSP).Results The levels of CEA and NSE in 120 WLM group were (396.62 ± 148.74) and (9.09 ±0.90) μg/L,respectively,significantly higher than those of control group (t =2.583,2.463,P ＜ 0.05).The levels of CEA and NSE in treatment group were (70.89 ±44.71) and (4.31 ±1.37) μg/L,respectively,remarkably lower than those of 120 WLM group (t =2.921,2.526,P ＜0.05 ).The concentrations of CYFRA21-1 and p53 antibody were not significantly different among the three groups (t =1.713,1.963,P ＞ 0.05 ).The rate of p16 gene methylation in BALF cells in 120 WLM group was 16.67％,but in control group and treatment group did not arise p16 gene methylation in BALF cells.Conclusions FUZHENGJIDU would decrease the levels of CEA and NSE and the rate of p16 gene methylation,and could exert it's protective effect on rats exposed to high concentration of radon.

Objective To evaluate the efficacy of radiofrequency thermocoagulation guided by three-dimensional computer tomography(3-D CT)for the treatment of severe recurrent glossopharyngeal neuralgia(GPN). Methods Twenty-nine patients of both sexes with recurrent intractable GPN, aged 42-75 yr, with recurrent course of 1-8 yr, of Barrow Neurological Institute(BNI)Pain Scale(BNI-P) class Ⅳ or Ⅴ, were enrolled in this study. Percutaneous radiofrequency thermocoagulation was applied to the middle and lower segment of the styloid process of the glossopharyngeal nerve under 3D CT guidance. Before operation and at 72 h, 6 months and 1 year after operation, BNI-P class and BNI Numbness Scale scores were recorded, and effective treatment and operation-related complications were also recorded. Re-sults Nineteen patients underwent one operation, 8 patients underwent two operations, and 2 patients un-derwent three operations. BNI-P class was significantly lower at each time point after operation than before operation(P<0.05). The rate of effective treatment was 100% at 72 h and 6 months after operation and 97% at 1 yr after operation. Different degrees of dysesthesias at the posterior part of the tongue on the affect-ed side occurred after operation and disappeared at 1 yr after operation. Operation-related nausea and vomi-ting, facial nerve damage, accessory nerve damage and fatality were not observed. Conclusion 3D CT-guided radiofrequency thermocoagulation of the glossopharyngeal nerve provides reliable efficacy and higher safety for the patients with severe recurrent GPN.

Objective To observe the clinical efficacy of Yuganlong capsule combined with entecavir in treatment of liver fibrosis in patients with chronic hepatitis B cirrhosis. Methods A total of 57 cases of patients with chronic hepatitis B cirrhosis were randomly divided into treatment group(30 cases given entecavir) and control group(27 cases treated with Yuganlong capsule combined with entecavir).Fibroscan values,hepatic fibrosis indexes(HA,LN,C-Ⅳ,PC-Ⅲ),liver function index(ALT,AST,GGT,T-BiL),and ultrasonic imaging index(inner diameters of portal vein,thickness of spleen) were detected. Results Before treatment, all indicatorshad no significant differences between the two groups(P>0.05).After 96 weeks of treatment,the Fibroscan value,HA, LN,C-Ⅳ,ALT,AST and portal vein diameter were significantly reduced in the treatment group as compared with those before treatment(all P<0.05),and there were significant differences between the treatment group and the control group after the treatment (all P<0.05). Conclusion The effect of Yuganlong capsule combined with entecavir in the treatment of chronic hepatitis B liver cirrhosis is better than that of using entecavir alone to improve liver function and liver fibrosis.
