A brief effective screening protocol for identifying cataract patients with binocular vision anomalies.

Background: To compare the effectiveness of a brief binocular vision screening protocol to a comprehensive examination for detecting binocular vision anomalies before and after cataract surgery.

Methods: A comprehensive binocular vision test battery as a gold standard were administered on recruited patients before the first surgery and at the third visit after surgery on the second eye. A receiver operating characteristic (ROC) curve was plotted to illustrate the diagnostic ability of each test.

The variations of TRBV genes usages in the peripheral blood of a healthy population are associated with their evolution and single nucleotide polymorphisms.

T cell receptors (TCRs) are a class of T cell surface molecules that recognize the antigen-derived peptides presented by the major histocompatibility complex (MHC) and are able to trigger a series of immune responses. TCRs are important members of the adaptive immune system that arose in the jawed fish 500 million years ago. T cell receptor beta variable (TRBV) genes have been widely used to characterize TCR repertoires.

[Responses of peginterferon-alpha 2a antiviral therapy in chronic hepatitis B patients].

Objective: To study the responses of peginterferon-alpha 2a antiviral therapy in chronic hepatitis B (CHB) patients.

Methods: One hundred two CHB patients with their serum ALT values higher than 2x the upper limit of the normal (ULN) were divided into a HBeAg-positive and a HBeAg-negative group. All patients were treated with peginterferon-alpha 2a by subcutaneous injection (180 microgram once weekly).
