The role of PD-L1 in EGFR-mutant non-small cell lung cancer.

Lung cancer remains the leading cause of cancer-related deaths globally. In China, nearly half of non-small cell lung cancer (NSCLC) patients carry epidermal growth factor receptor (EGFR) mutations. EGFR tyrosine kinase inhibitors (EGFR-TKIs) have significantly improved the prognosis for patients with EGFR mutations and are considered the preferred treatment for these individuals.

Self-disclosure and reproductive concerns among breast cancer female patients: the chain mediation model of couples' cancer-related communication problems and relationship intimacy.

Purpose: Reproductive concerns are prevalent in the female breast cancer patient population and increase existential distress. Although self-disclosure significantly correlated reproductive concerns, the exact mechanism of action is unknown. Based on previous theoretical studies on couples' cancer-related communication problems and intimacy in couples, this study constructed a chain mediation model to investigate whether the two variables mediate the relationship between self-disclosure and reproductive concerns.

Dietary risk factors in Crohn's disease and ulcerative colitis: a cohort study with paired healthy relatives as controls.

Purpose: Conflicting results have been reported on dietary factors in inflammatory bowel diseases (IBDs). Here, we compared the dietary intakes of IBD patients with those of paired healthy relatives (HRs), aiming to minimize the impact of genetic and environmental confounders.

Methods: Patients with Crohn's disease (CD, N = 45) and ulcerative colitis (UC, N = 20), their paired HRs (N = 45, N = 20) and healthy non-relative (HNR, N = 25, N = 55) controls were recruited.

Effects of different feeding strategies on egg production, eggshell quality, tibial mass and intestinal calcium transporter expression in laying hens.

1. This study examined feeding practices that could affect the expression of intestinal calcium transporter gene, tibial mass, eggshell quality and production performance in 25-week-old Hy-Line Brown Laying Hens.2.

Research on Wet Etching Techniques for GaInAs/AlInAs/InP Superlattices in Quantum Cascade Laser Fabrication.

Wet etching is the mainstream fabrication method for single-bar quantum cascade lasers (QCLs). Different etching solutions result in varying etching effects on III-V semiconductor materials. In this study, an efficient and nearly ideal etching solution ratio was proposed for simultaneously etching both InP and GaInAs/AlInAs, and the surface chemical reactions induced by each component of the etching solution during the process were investigated.
