Silencing aquaporin 1 inhibits autophagy to exert anti-rheumatoid arthritis effects in TNF-α-induced fibroblast-like synoviocytes and adjuvant-induced arthritis rats : Names of authors.

Objective: Fibroblast-like synoviocytes (FLS) are key players in rheumatoid arthritis (RA) by resisting apoptosis via increased autophagy. Elevated synovial aquaporin 1 (AQP1) affects RA FLS behaviors, but its relationship with FLS autophagy is unclear. We aim to clarify that silencing AQP1 inhibits autophagy to exert its anti-RA effects.

Freeze-Thaw Cycle Durability and Mechanism Analysis of Zeolite Powder-Modified Recycled Concrete.

The inferior mechanical performance and freeze-thaw (FT) resistance of recycled concrete are mostly due to the significant water absorption and porosity of recycled coarse particles. In this study, different dosages of zeolite powder were used in recycled concrete. A series of macroscopic tests were used to evaluate the workability and FT durability of zeolite powder-modified recycled concrete (ZPRC).

CPD-002, a novel VEGFR2 inhibitor, relieves rheumatoid arthritis by reducing angiogenesis through the suppression of the VEGFR2/PI3K/AKT signaling pathway.

Synovial angiogenesis is a key player in the development of rheumatoid arthritis (RA), and anti-angiogenic therapy is considered a promising approach for treating RA. CPD-002 has demonstrated efficacy in suppressing tumor angiogenesis as a VEGFR2 inhibitor, but its specific impacts on RA synovial angiogenesis and possible anti-RA effects need further study. We examined the influences of CPD-002 on the migration and invasion of human umbilical vein endothelial cells (HUVECs) and its impacts on HUVECs' tube formation and vessel sprouting ex vivo.

Shikonin suppresses rheumatoid arthritis by inducing apoptosis and autophagy via modulation of the AMPK/mTOR/ULK-1 signaling pathway.

Background: The overproliferation of fibroblast-like synoviocytes (FLS) contributes to synovial hyperplasia, a pivotal pathological feature of rheumatoid arthritis (RA). Shikonin (SKN), the active compound from Lithospermum erythrorhizon, exerts anti-RA effects by diverse means. However, further research is needed to confirm SKN's in vitro and in vivo anti-proliferative functions and reveal the underlying specific molecular mechanisms.

Matrine alleviates hypoxia-induced inflammation and pulmonary vascular remodelling via RPS5/NF-κB signalling pathway.

Hypoxia-induced vasoconstriction and vascular remodelling are the main pathological features of hypoxic pulmonary arterial hypertension (HPAH), and inflammation is participated in the occurrence of pulmonary vascular remodelling (PVR). Matrine is an alkaloid with the effects of anti-inflammation, antifibrosis and antitumour. But, few studies have explored the role of matrine in regulating PVR, and the related mechanisms are still unknown.

SIRT6 inhibits hypoxia-induced pulmonary arterial smooth muscle cells proliferation via HIF-1α/PDK4 signaling.

SIRT6 is an NAD-dependent protein that plays a vital role in regulating the cell proliferation, differentiation and apoptosis. Abnormal proliferation of pulmonary artery smooth muscle cells (PASMCs) in peripheral vascular is one of the major pathological findings of pulmonary vascular remodeling in pulmonary arterial hypertension (PAH). However, whether SIRT6 is involved in hypoxia-induced proliferation of PASMCs and its possible mechanisms remain unknown.

Efficacy and safety of riociguat in the treatment of chronic thromboembolic pulmonary arterial hypertension: A meta-analysis.

Background: Riociguat is a novel soluble guanylate cyclase stimulator, and has been widely used for the treatment of pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension (CTEPH). Some studies found that riociguat had better effects on CTEPH and proved to be safe, but the results were not utterly consistent. Therefore, the purpose of this study was to comprehensively evaluate the efficacy and safety of riociguat in the treatment of CTEPH.

Cysteinyl Leukotriene Receptor 2 is Involved in Inflammation and Neuronal Damage by Mediating Microglia M1/M2 Polarization through NF-κB Pathway.

Microglia activation plays a key role in regulating inflammatory and immune reaction during cerebral ischemia and it exerts pro-inflammatory or anti-inflammatory effect depending on M/M polarization phenotype. Cysteinyl leukotriene 2 receptor (CysLTR) is a potent inflammatory mediator receptor, and involved in cerebral ischemic injury, but the mechanism of CysLTR regulating inflammation and neuron damage remains unclear. Here, we found that LPS and CysLTR agonist NMLTC significantly increased microglia proliferation and phagocytosis, up-regulated the mRNA expression of M polarization markers (IL-1β, TNF-α, IFN-γ, CD86 and iNOS), down-regulated the expression of M polarization markers (Arg-1, CD206, TGF-β, IL-10, Ym-1) and increased the release of IL-1β and TNF-α.

A systematic review and meta-analysis of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) versus traditional staged hepatectomy.

It is still controversial whether associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) or traditional staged hepatectomy such as portal vein embolization (PVE) and 2-staged hepatectomy (TSH) is better. The aim of this study was to compare these 3 available strategies in extended hepatectomy.Trials were identified by searching MEDLINE, PubMed, the Cochrane Library, and Embase and additional articles were identified by hand searching.

Lifestyle interventions to alleviate side effects on prostate cancer patients receiving androgen deprivation therapy: a meta-analysis.

Background: Prostate cancer (PCa) patients receiving androgen deprivation therapy (ADT) are prone to suffer a series of potential side effects, including metabolic change, declining physical strength and worsening fatigue. Recent studies found that the change of lifestyle interventions can help to alleviate some adverse reactions, but the results were controversial. Therefore, the aim of this review was to comprehensively evaluate the effects of these lifestyle interventions on the side effects on PCa patients who received ADT.

Evaluating and optimizing the operation of the hydropower system in the Upper Yellow River: A general LINGO-based integrated framework.

The hydropower system in the Upper Yellow River (UYR), one of the largest hydropower bases in China, plays a vital role in the energy structure of the Qinghai Power Grid. Due to management difficulties, there is still considerable room for improvement in the joint operation of this system. This paper presents a general LINGO-based integrated framework to study the operation of the UYR hydropower system.
