Linguistic and cultural validation of symptom questionnaire for visual dysfunctions (SQVD) for psychometric analysis in the Chinese context.

The Spanish scale symptom questionnaire for visual dysfunctions (SQVD) was sinicized and tested for reliability and validity in the Chinese context, employing both classical measurement theory and item response theory. A meticulous translation was conducted using the modified Brislin translation model, with input from experts for cross-cultural debugging and in-depth review. Following a pre-survey study, the Chinese version of the SQVD was finalized.

Expansion of CD14(+)CD16(+) monocytes is related to acute leukemia.

Objective: Aim to investigate the proportion of CD14(+)CD16(+) monocytes and understand the pathogenesis of this monocyte subset in acute leukemia.

Methods: Flow cytometry was utilized to study the phenotype expression of CD14(+)CD16(+) monocytes and CD3(+) T lymphocytes in peripheral blood derived from patients with acute leukemia. All the data were analyzed by SPSS 13.

Anti-HCMV and KSHV effect of a trapping ligand antagonist for herpesvirus-encoded GPCR.

We have found and synthesized a trapping ligand peptide H22-LP (the conservative sequence is NAHCALL) from a random phage library according to the broad-spectrum trapping receptor H22, which derived from the residue 14-35 near the N-terminal region of receptor US28 on HCMV. In this study, we will evaluate its potential as an efficient antagonist of US28 and the anti-virus activity, acting as a broad spectrum chemokine receptors antagonist. Stable expression of US28 and ORF74 in NIH/3T3 cells were successfully constructed in vitro.
