Schisandra chinensis lignans improve insulin resistance by targeting TLR4 and activating IRS-1/PI3K/AKT and NF-κB signaling pathways.

Schisandra chinensis, a traditional Chinese medicine, has been widely applied in China to treat diabetes and its complications. The aim of this study was to discover the active compounds and explain related molecular mechanism contributing to the anti-diabetic effect of Schisandra chinensis. Herein, the therapeutic effects of Schisandra chinensis extracts on type 2 diabetes mellitus (T2DM) were firstly confirmed in vivo.

Clinical and HLA genotype analysis of immune checkpoint inhibitor-associated diabetes mellitus: a single-center case series from China.

Objective: To investigate the clinical characteristics and HLA genotypes of patients with immune checkpoint inhibitor-associated diabetes mellitus (ICI-DM) in China.

Methods: We enrolled 23 patients with ICI-DM and 51 patients with type 1 diabetes (T1D). Clinical characteristics of the patients were collected.

Memory T cells delay the progression of atherosclerosis via AMPK signaling pathway.

Background: Memory T cells play a key role in the development of atherosclerosis (AS). This study aimed to investigate the role of AMPK signaling pathway of spleen memory T cells in the pathogenesis of AS in high-fat diet (HFD) fed mice.

Methods: Mice were divided into 5 groups: normal group, AS group, AS + solvent group, AS + Compound C (AMPK inhibitor) group and AS + A-769662 (AMPK agonist) group.

Imbalance of T-helper 1/T-helper 2 cytokines and impaired glucose tolerance among patient with acute coronary syndrome.

Purpose: The balance between T helper (Th) cells Th1- and Th2-related cytokines plays a key role in the clinical process of acute coronary syndrome (ACS) and type 2 diabetes mellitus (T2DM) or impaired glucose tolerance (IGT). The objective of this study was to assess the status of Th1/Th2 cytokines in patients with ACS and T2D or IGT.

Methods: A total of 201 ACS patients were enrolled in the study.

Effects of arterial blood on the venous blood vessel wall and differences in percentages of lymphocytes and neutrophils between arterial and venous blood.

Vascular sclerosis mostly occurs in arteries and is mainly related to anatomic structure and hemodynamics of artery. This study aimed to investigate effects of arterial blood on vein wall and explore differences of composition between arterial and venous blood.Ultrasound was used to examine the distal venous structure of arteriovenous fistula in uremia patients.

A novel mutation in autoimmune regulator gene causes autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy.

Background: Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy syndrome (APECED) is a rare autosomal recessive disease due to mutations in the autoimmune regulator (AIRE) gene, which encodes a transcription factor that induces the expression of peripheral tissue-specific antigens in medullary thymic epithelial cells.

Aim: The purpose of this study was to identify the underlying genetic cause in a Chinese family diagnosed with APECED.

Method: Peripheral blood samples were collected from family members.
