Background: Since the implementation of China's comprehensive two-child policy, the prevalence of long interpregnancy intervals (IPI) and advanced maternal age has increased. However, previous studies in China have mostly focused on the relationship between short IPIs and adverse perinatal outcomes, while neglecting maternal age as a potential confounder.

Methods: We conducted a retrospective cohort study of 23,899 pregnant women who delivered between January 1, 2017 and December 31, 2019 at Chengdu Women's and Children's Central Hospital and West China Second Hospital of Sichuan University.

Targeting p38γ synergistically enhances sorafenib-induced cytotoxicity in hepatocellular carcinoma.

Cell Biol Toxicol

January 2025

Division of Abdominal Tumor Multimodality Treatment, Cancer Center and Laboratory of Molecular Targeted Therapy in Oncology, West China Hospital, Sichuan University, 610041, Chengdu, Sichuan Province, China.

Sorafenib (Sora) is a first-line treatment for patients with advanced hepatocellular carcinoma (HCC). It can significantly improve the survival rate of patients with advanced HCC, but it is prone to drug resistance during treatment, so the therapeutic effect is extremely limited. Here, we demonstrate that an elevated expression of protein kinase p38γ in hepatocellular carcinoma cells diminishes the tumor cells' sensitivity to Sora.

Pediatr Nephrol

January 2025

Department of Anesthesiology, West China Hospital, Sichuan University, No. 37 Guoxue Lane, Wuhou District, Chengdu, 610000, Sichuan, China.

Background: Cardiac surgery-associated acute kidney injury (CSA-AKI) is a notably common complication in pediatrics, with an incidence rate ranging from 15 to 64%. This rate is significantly higher than that observed in adults. Currently, there is a lack of substantial evidence regarding the association between intraoperative blood pressure variability (BPV) during cardiac surgery with cardiopulmonary bypass (CPB) and the development of AKI in pediatric patients.

The magnetization strategy of isoquinoline alkaloids has been successfully used in the extraction and isolation, but the effect of the magnetization on biological activities of those alkaloids still deserves further investigation. Therefore, the antibacterial, lipid-lowering and antioxidant activities of five isoquinoline alkaloids (berberine, tetrahydroberberine, palmatine, tetrahydropalmatine and tetrahydropapavine) before and after magnetization were compared in this study, and the results showed that the relevant activities were enhanced after magnetization. Additionally, among the five magnetic derivatives studied, berberine magnetic derivative ([Ber·H][FeCl]) had the best antibacterial effect on S.

High-density lipoprotein nanoparticles spontaneously target to damaged renal tubules and alleviate renal fibrosis by remodeling the fibrotic niches.

Nat Commun

January 2025

College of Polymer Science and Engineering, West China School of Public Health, Med-X center of materials, Sichuan University, Chengdu, Sichuan, 610065, China.

Chronic kidney disease (CKD) ultimately causes renal fibrosis and end-stage renal disease, thus seriously threatens human health. However, current medications for CKD and fibrosis are inefficient, which is often due to poor targeting capability to renal tubule. In this study, we discover that biomimetic high-density lipoprotein (bHDL) lipid nanoparticles possess excellent targeting ability to injured tubular epithelial cells by kidney injury molecule-1(KIM-1) mediated internalization.

Bone Res

January 2025

Department of Orthodontics, State Key Laboratory of Oral Diseases, National Clinical Research Center for Oral Diseases, West China Hospital of Stomatology, Sichuan University, Chengdu, Sichuan, China.

Circadian rhythm is ubiquitous in nature. Circadian clock genes such as Bmal1 and Clock form a multi-level transcription-translation feedback network, and regulate a variety of physiological and pathological processes, including bone and cartilage metabolism. Deletion of the core clock gene Bmal1 leads to pathological bone alterations, while the phenotypes are not consistent.

Optimized Interface Engineering Enhances Carrier and Phonon Scattering for Superior Thermoelectric Performance in Yb-Filled Skutterudites.

ACS Appl Mater Interfaces

January 2025

Key Laboratory of Radiation Physics and Technology, Ministry of Education, Institute of Nuclear Science and Technology, Sichuan University, Chengdu 610064, China.

Thermoelectric (TE) performance in materials is often constrained by the strong coupling between carrier and phonon transport, necessitating trade-offs between electrical and thermal properties that limit improvements in the figure of merit (). Herein, a novel strategy is proposed to achieve simultaneous energy filtering and enhanced phonon scattering, effectively optimizing the TE properties of CoSb-based skutterudites. By introducing CuTe nanoprecipitates into the YbCoSb matrix, interfacial barriers are formed, which selectively filter low-energy charge carriers, significantly improving the Seebeck coefficient while maintaining high carrier mobility.
