Prediction for HBsAg seroconversion in children with chronic hepatitis B.

Background: To establish a prediction of HBsAg seroconversion in children with chronic hepatitis B (CHB), so as to help clinicians to choose therapeutic strategy.

Methods: A total of 63 children with HBeAg-positive CHB aged 1 to 17 years, who admitted to the fifth medical center of Chinese PLA general hospital and treated with interferon α (IFNα) 48 weeks were enrolled, the clinical data were measured. Based on the results of HBsAg seroconversion (HBsAg < 0.

Power flow analysis and optimal locations of resistive type superconducting fault current limiters.

Based on conventional approaches for the integration of resistive-type superconducting fault current limiters (SFCLs) on electric distribution networks, SFCL models largely rely on the insertion of a step or exponential resistance that is determined by a predefined quenching time. In this paper, we expand the scope of the aforementioned models by considering the actual behaviour of an SFCL in terms of the temperature dynamic power-law dependence between the electrical field and the current density, characteristic of high temperature superconductors. Our results are compared to the step-resistance models for the sake of discussion and clarity of the conclusions.

IL28B SNP rs12979860 is the Critical Predictor for Sustained Viral Response in Chinese Children Aged 1 to 6 Years with Chronic Hepatitis C.

Clinical data on children with chronic hepatitis C (CHC) remain extremely limited. This study investigated sustained virologic response (SVR) to alfa-interferon 2b plus RBV treatment in children aged 1-6 years with unsafe injection-acquired CHC. 154 children with CHC aged 1 to 6 years were enrolled, 101 of them were male (65.

A novel method for detection of HBVcccDNA in hepatocytes using rolling circle amplification combined with in situ PCR.

Background: Intrahepatic hepatitis B virus (HBV) covalently closed circular DNA (cccDNA) is the original template for HBV replication. The persistence of cccDNA is responsible for the recurrence of HBV infection. The detection of cccDNA can help the development of new antiviral drugs against HBV replication links, and reduce the resistance and recurrence as well as to discover extrahepatic HBV infection.

[Changes of alveolar macrophage phagocytosis and TNF-alpha, IL-6 of rats with Pneumocystis pneumonia].

Objective: To observe the changes of alveolar macrophage (AM) phagocytosis and the levels of TNF-alpha and IL-6 in AM supernatants and bronchoalveolar lavage fluid (BALF) of rats with Pneumocystis pneumonia (PCP).

Methods: Wistar rats were injected with dexamethasone intramuscularly and continually to establish the model of PCP, the AM phagocytosis and levels of TNF-alpha and IL-6 in AM supernatants and BALF of rats with PCP were detected, meanwhile, the normal controls were set.

Results: The phagocyting percentage [(20.

[Apoptosis of human leukemia K562 cell in vitro induced by Toxoplasma gondii].

Objective: To investigate whether the Toxoplasma gondii can inhibit proliferation of human leukemia K562 cells and/or induce apoptosis of the cells in vitro. Methods K562 cells (5x10(4)/ml) were harvested at mid-exponential phase and planted in 96 well plates with 100 microl each and in 50 ml culture bottles, 1.5 ml each.
