Ultrathin polymer membrane for improved hole extraction and ion blocking in perovskite solar cells.

Highly efficient perovskite solar cells (PSCs) in the n-i-p structure have demonstrated limited operational lifetimes, primarily due to the layer-to-layer ion diffusion in the perovskite/doped hole-transport layer (HTL) heterojunction, leading to conductivity drop in HTL and component loss in perovskite. Herein, we introduce an ultrathin (~7 nm) p-type polymeric interlayer (D18) with excellent ion-blocking ability between perovskite and HTL to address these issues. The ultrathin D18 interlayer effectively inhibits the layer-to-layer diffusion of lithium, methylammonium, formamidium, and iodide ions.

Efficacy and Safety of Tranexamic Acid on Hidden Blood Loss in Osteoporotic Vertebral Compression Fractures Patients Treated with Percutaneous Kyphoplasty: A Prospective Randomized Controlled Trial.

Purpose: To evaluate the efficacy and safety of intravenous tranexamic acid (TXA) in patients undergoing percutaneous kyphoplasty (PKP), and identify the factors influencing hidden blood loss (HBL).

Methods: This randomized, placebo-controlled trial included 146 patients undergoing PKP surgery from September 2023 to July 2024. Patients were randomly assigned into the TXA group (75 patients received 1.

Popliteal Artery Injury After Arthroscopic Knee Surgery: A Retrospective Multicenter Cohort Study.

Objective: Popliteal artery injury is a rare but serious complication of arthroscopic knee surgery. The absence of comprehensive data and standardized guidelines underscores the urgent need for further investigation. This study examines the incidence, risk factors, management strategies, and long-term outcomes of popliteal artery injury in the context of arthroscopic knee procedures.

Understanding the impact of COVID-19 on quality of life using surveys and Mendelian randomization.

The COVID-19 pandemic has significantly impacted the quality of life (QoL) of individuals in China, affecting both their physical and mental well-being. This study aims to comprehensively analyze the factors influencing QoL in China during the pandemic. In 2022, we collected data using a self-developed questionnaire (dataset 2) and obtained dataset 1 from the 2021 China General Social Survey (CGSS).

Efficacy and safety of Chinese tonic medicines for treating sepsis or septic shock: a protocol for a systematic review and Bayesian network meta-analysis of randomized controlled trials.

Background: Sepsis is a life-threatening organ dysfunction with high morbidity and mortality. Various studies have demonstrated the effectiveness of Chinese tonic medicines (CTMs) in treating sepsis or septic shock. However, trials directly comparing the efficacy and safety of different CTMs for sepsis or septic shock are still lacking.
