Objectives: Hypertension and hypertensive disorders of pregnancy (HDP) are common diseases in women at different stages, which affect women's physical and mental health, and the impact of the latter on the offspring cannot not be ignored. Observational studies have investigated the correlation between uterine leiomyoma (UL) and the above conditions, but the relationship remains unclear. In this study, we employed two-sample Mendelian randomization (MR) analysis to assess the association between UL and hypertension, HDP, as well as blood pressure.

Although various anti-osteoporosis drugs are available, the limitations of these therapies, including drug resistance and collateral responses, require the development of novel anti-osteoporosis agents. Rhizoma Drynariae displays a promising anti-osteoporosis effect, while the effective component and mechanism remain unclear. Here, we revealed the therapeutic potential of Rhizoma Drynariae-derived nanovesicles (RDNVs) for postmenopausal osteoporosis and demonstrated that RDNVs potentiated osteogenic differentiation of human bone marrow mesenchymal stem cells (hBMSCs) by targeting estrogen receptor-alpha (ER).

Background: It is unclear whether short-term blood pressure variability (BPV) is associated with target organ damage in patients with non-dialysis chronic kidney disease (CKD).

Methods: A cross-sectional, single-center study was conducted among 3442 non-dialysis CKD patients hospitalized in the department of Nephrology of the Fifth Affiliated Hospital of Sun Yat-sen University from November 2017 to July 2022 and collected the demographic, laboratory, clinic blood pressure, ambulatory blood pressure data, and short-term BPV assessed by the weighted standard deviation (wSD) derived from ambulatory blood pressure monitoring (ABPM). Multivariate logistic analyses were used to evaluate the independent effects between short-term BPV and subclinical target organ damage, including left ventricular hypertrophy (LVH), abnormal carotid intima-media thickness (CIMT), low estimated glomerular filtration rate (eGFR), and albuminuria.

Article Synopsis
  • Natural killer/T-cell lymphoma (NKTCL) is a complex and aggressive disease, with a focus on a rare subtype called non-upper aerodigestive tract NKTCL (NUAT-NKTCL), which shows poor prognosis and lacks adequate treatment strategies.
  • In a study of 1589 NKTCL patients, 196 were identified with NUAT-NKTCL, revealing they had worse clinical outcomes and distinct genetic mutations compared to upper aerodigestive tract patients.
  • The addition of anti-PD-1 immunotherapy to standard chemotherapy significantly improved patients' survival rates, highlighting the need for more research on treatment effectiveness and biomarkers for NUAT-NKTCL.

Ischemia/reperfusion (I/R)-induced acute kidney injury (AKI) is a common clinical syndrome with high morbidity and mortality. Ferroptosis, a newly discovered form of oxidative cell death, is involved in the pathogenesis of renal I/R injury; however, the underlying mechanism remains to be explored. Here, we reported that site 1 protease (S1P) promotes ischemic kidney injury by regulating ferroptotic cell death of tubular epithelial cells.

Int J Mol Sci

December 2023

Division of Nephrology, Department of Medicine, The Fifth Affiliated Hospital Sun Yat-Sen University, Internal Medicine Building Room #606, 52 Meihua Dong Road, Zhuhai 519000, China.

Diabetes nephropathy (DN) is the leading cause of end-stage renal disease (ESRD) worldwide, and podocyte injury is the central contributor to the progression of DN. Despite the emerging evidence that has established the importance of podocyte endoplasmic reticulum (ER) stress in the pathogenesis of DN, abnormal protein O-GlcNAcylation is also augmented. Currently, the mechanism associating these two hyperglycemia-induced disorders remains poorly understood.

  • - Checkpoint inhibitors like tislelizumab have shown effectiveness in treating recurrent/metastatic nasopharyngeal cancer (R/M NPC), significantly improving progression-free survival (PFS) compared to placebo when combined with chemotherapy.
  • - In a clinical trial (RATIONALE-309), patients receiving tislelizumab with chemotherapy had better outcomes regardless of their programmed death-ligand 1 expression, and the overall safety of the treatment was similar to the placebo group.
  • - Gene expression profiling identified specific tumor characteristics that were associated with better PFS in patients treated with tislelizumab-chemotherapy, suggesting this combination should be considered for first-line treatment in R/M NPC and could help select the best candidates for therapy
