Relationship between serum quantitative HBsAg and HBV DNA levels in chronic hepatitis B patients.

Serum hepatitis B surface antigen (HBsAg) level has been developed as an important marker to predict treatment outcome recent years. The authors aimed to identify the correlation between quantitative HBsAg and hepatitis B virus (HBV) DNA level in chronic hepatitis B (CHB) patients and explore whether quantitative HBsAg can be used as a surrogate marker of serum HBV DNA for CHB patients. One hundred seventy-three patients were included in this study.

Inhibition of Sonic Hedgehog Signaling Pathway by Thiazole Antibiotic Thiostrepton Attenuates the CD44+/CD24-Stem-Like Population and Sphere-Forming Capacity in Triple-Negative Breast Cancer.

Background/aim: Triple-negative breast cancer (TNBC) represents a particular clinical challenge because these cancers do not respond to endocrine therapy or other available targeted agents. The lack of effective agents and obvious targets are major challenges in treating TNBC. In this study we explored the cytostatic effect of thiazole ring containing antibiotic drug thiostrepton on TNBC cell lines and investigated the molecular mechanism.

[Studies on the effect of Ginkgo biloba extracts on NF-kappaB pathway].

Objective: To investigate NF-kappaB and IkappaBalpha activities in HL-60 induced by TNF-alpha in order to understand the molecular mechanism of GbE in asthma treatment.

Methods: The amount of IkappaBalpha in HL-60 cells stimulated by TNF-alpha and GbE was measured by western blotting. Plasmid pNF-kappaB-LuC was transfected and NF-kappaB activity was analyzed by measuring the expression level of luciferase.

[Serum sCD40L detection for risk evaluation of acute coronary syndromes].

Objective: To investigate the value of serum soluble CD40 ligand (sCD40L) detection in risk evaluation of acute coronary syndromes (ACS).

Methods: This study involved 200 patients with established diagnosis of ACS, with death or nonfatal myocardial infarction as the end point of observation during the 6-month-long follow-up. Blood samples were obtained from the patients within the initial 72 h of ACS onset, and the levels of sCD40L and C-reactive protein (CRP) were determined with enzyme-linked immunosorbent assay (ELISA).
