Clinical Medicine of China 2010;26(10):1065-1067
Objective To explore the correlation between HBV-DNA and serum HBV markers quantitative detection and determine its diagnosis value in hepatitis B virus infection. Methods The HBV-DNA was measured by fluorescence quantitative PCR and hepatitis B virus was detected by time-resolved fluorescence immunoassay (TRFIA). The relationship between the two tests was analyzed statistically using software. Results Detection of HBV-DNA in the peripheral blood of patients with HBsAg (+), HBeAg (+), HBcAb ( + ) showed 92. 9% (79/85) positive rate,and the average DNA copy number was (4.31 ± 1.64) × 106 copies/ml. While the detection of HBV-DNA in the peripheral blood of patients with HBsAg ( + ), HBeAb ( + ), HBcAb ( + ) showed 47.7% (105/220) positive rate, and the average DNA copy number was (2.47 ± 2. 21 ) × 104 copies/ml. In normal controls,blood HBV-DNA detection was negative. Furthermore, HBV-DNA copy number correlated positively with HbeAg quantitation (r = 0. 59, P = 0. 041 ). However, we found no significant correlation between HBV-DNA copy number and HbsAg quantititation (r = 0.221, P = 0.077). Conclusions Different HBV-M had diverse correlation with HBV-DNA number, comprehensive detection of them would be better to assist clinical diagnosis and evaluate the response to treatments.

Conclusion:The CBL teaching method can effectively help interns master professional theoretical knowledge and clinical practice skills of cardiothoracic surgery, which has obtained satisfactory teaching results and is worthy of promotion.
8.Uncoupling protein 2 in regulatory mechanisms and basical experiments
International Journal of Pediatrics 2016;43(9):700-703
Uncoupling protein 2(UCP2)is a proton transporter which presents in the mitochondrial inner membrane. Recent studies have found that UCP2 plays important roles in protecting mitochondria functions,re-ducing mitochondrial ROS generation by inducing proton leak across the inner mitochondrial membrane and pro-moting mild uncoupling which leading to a decrease in the mitochondrial inner membrane′s potential. Because of its antioxidant function,UCP2 has been studied in several domains. This review provides novel insights into the molecular mechanisms,by which the activity of UCP2 is regulated and describe novel findings concerning basical experiments of UCP2.
