Circadian rhythm disruption (CRD), stemming from sleep disorders and/or shift work, is a risk factor for reproductive dysfunction. CRD has been reported to disturb nocturnal melatonin signaling, which plays a crucial role in female reproduction as a circadian regulator and an antioxidant. The hypothalamic-pituitary-ovarian (HPO) axis regulates female reproduction, with luteinizing hormone (LH) pulse pattern playing a pivotal role in folliculogenesis and steroidogenesis.

Background: Irritable bowel syndrome (IBS) is a common gastrointestinal disease. Recently, an increasing number of studies have shown that Toll-like receptor 4 (TLR4), widely distributed on the surface of a variety of epithelial cells (ECs) and immune sentinel cells in the gut, plays a vital role in developing IBS.

Department of Nuclear Medicine, West China Hospital of Sichuan University, Chengdu, China; Research Unit of Psychoradiology, Chinese Academy of Medical Sciences, Chengdu, China. Electronic address:

Objective: The overlap of affective disturbance and psychosis considerably makes it complex to determine the etiology of bipolar disorder (BD) and develop targeted interventions. The present study aimed to determine the white matter microstructural alterations that distinguish between BD with psychosis (BDP) and BD with no psychosis (BDNP) to identify patients who may specifically benefit from appropriately effective treatments.

Methods: Diffusion-weighted magnetic resonance images were acquired from 38 participants with BDP, 52 participants with BDNP and 70 healthy controls (HCs).

Background: Phosphorylation-dephosphorylation is one of the most common and critical cellular activities. It is essential for cell cycle control and leads to large changes in protein conformation, which can alter protein function and coordinate multiple functions such as cell metabolism, gene transcription and translation, signaling, growth, differentiation, and apoptosis. Alterations in the phosphorylated proteome have been shown in many cancers.

State Key Laboratory of Primate Biomedical Research, Institute of Primate Translational Medicine, Kunming University of Science and Technology, No. 727 Jingming South Road, Chenggong District, Kunming 650500, China.

Postpartum depression and postpartum depression with anxiety, which are highly prevalent and debilitating disorders, become a growing public concern. The high overlap on the symptomatic and neurobiological levels led to ongoing debates about their diagnostic and neurobiological uniqueness. Delineating the shared and disorder-specific intrinsic functional connectivities and their causal interactions is fundamental to precision diagnosis and treatment.

Radiation therapy was initially used in dermatology to treat various skin diseases, including acne vulgaris, keloids, plantar warts, tinea capitis and hirsutism. Although it is no longer used in the treatment of many of these diseases, radiation therapy still plays a crucial role in the treatment of keloids, skin cancer and solid organ malignancies. In the past 20 years, the widespread use of intensity-modulated radiation therapy has significantly increased in the management of tumor growth in multiple cancer sites and reduced the incidence of complications in normal organs.

Background: The Coronavirus disease 2019 (COVID-19) pandemic has emerged as a global health crisis, with clinical manifestations including those suggesting injury to various organs such as the ovaries, which implies that it extends beyond respiratory infections. Changes in gut microbiota may exhibit correlations with the mechanisms and stages of severity in COVID-19, as well as a link with sex hormones, embryo development, and pregnancy. Controlled ovarian stimulation (COS) is used to induce the development of multiple high-quality follicles during in vitro fertilization (IVF).

Background: Abraxane plays a crucial role in the treatment of various types of cancer, despite the considerable attention it has garnered for its adverse drug events (ADEs). Nevertheless, there is currently a significant lack of comprehensive real-world pharmacovigilance studies on the ADEs associated with Abraxane.

Methods: We conducted a retrospective analysis of ADEs associated with Abraxane using data mining from the FAERS database, analyzing data from 2005 to 2023.

Key Laboratory of Birth Defects and Related Diseases of Women and Children of MOE, State Key Laboratory of Biotherapy, West China Second University Hospital, Sichuan University, Chengdu, China. Electronic address:

Gynecological tumors, primarily ovarian cancer (OC), cervical cancer (CC), and endometrial cancer (EC), have a significant global impact on women's health, characterized by high mortality rates. Emerging evidence underscores the pivotal role of altered glucose metabolism in the initiation and progression of these malignancies. Glucose metabolism, encompassing glycolysis, the tricarboxylic acid (TCA) cycle, oxidative phosphorylation, and the pentose phosphate pathway (PPP), among others, is intricately governed by a spectrum of key enzymes.

Oxidative stress in diabetes mellitus and its complications: From pathophysiology to therapeutic strategies.

Chin Med J (Engl)

August 2024

Department of Pharmacology, Key Laboratory of Drug-Targeting and Drug Delivery System of the Education Ministry and Sichuan Province, Sichuan Research Center for Drug Precision Industrial Technology, West China School of Pharmacy, Sichuan University, Chengdu, Sichuan 610041, China.

Oxidative stress due to aberrant metabolism is considered as a crucial contributor to diabetes and its complications. Hyperglycemia and hyperlipemia boost excessive reactive oxygen species generation by elevated mitochondrial respiration, increased nicotinamide adenine dinucleotide phosphate oxidase activity, and enhanced pro-oxidative processes, including protein kinase C pathways, hexosamine, polyol, and advanced glycation endproducts, which exacerbate oxidative stress. Oxidative stress plays a significant role in the onset of diabetes and its associated complications by impairing insulin production, increasing insulin resistance, maintaining hyperglycemic memory, and inducing systemic inflammation.

Injectable immunoregulatory hydrogels sequentially drive phenotypic polarization of macrophages for infected wound healing.

Bioact Mater

November 2024

National Engineering Research Center for Biomaterials, Sichuan University, 29# Wangjiang Road, Chengdu, Sichuan, 610064, China.

Regulating macrophage phenotypes to reconcile the conflict between bacterial suppression and tissue regeneration is ideal for treating infectious skin wounds. Here, an injectable immunoregulatory hydrogel (SrmE20) that sequentially drives macrophage phenotypic polarization (M0 to M1, then to M2) was constructed by integrating anti-inflammatory components and proinflammatory solvents. experiments demonstrated that the proinflammatory solvent ethanol stabilized the hydrogel structure, maintained the phenolic hydroxyl group activity, and achieved macrophages' proinflammatory transition (M0 to M1) to enhance antibacterial effects.
