Novel aspect of neprilysin in kidney fibrosis via ACSL4-mediated ferroptosis of tubular epithelial cells.

Although inhibition of neprilysin (NEP) might be a therapeutic strategy with the potential to improve the outcome of chronic kidney disease (CKD), the versatile function of NEP with its mechanism remains obscure in kidney fibrosis. In the study, we found that NEP was abnormally increased in tubular epithelial cells of CKD patients, as well as unilateral ureteral obstruction and adenine diet-induced mice. Treatment with a United States Food and Drug Administration-approved NEP inhibitor Sacubitrilat (LBQ657) could alleviate ferroptosis, tubular injury, and delay the progression of kidney fibrosis in experimental mice.

Evolution and major changes of the diagnosis and treatment protocol for COVID-19 patients in China 2020-2023.

Since the identification of the first case of pneumonia of unknown cause in 2019, the COVID-19 pandemic has spread the globe for over 3 years. As the most populous country in the world, China's disease prevention policies and response plans concern the health of the country's 1.4 billion people and beyond.

Dexmedetomidine improves DM-induced oxidative stress injury to protect liver function through Nrf2 pathway.

Objective: Diabetes mellitus-induced oxidative stress (OS) causes liver injury. Intraoperative pumping of dexmedetomidine (DEX) effectively reduced the postoperative OS response in patients with type 2 diabetes mellitus (T2DM) and had a certain protective effect on liver function. However, the mechanisms of the protective effect on the liver remained unclear.

Long-segment restrictive tear of radial artery under ultrasound guide for arteriovenous fistula by PTA: A case report.

Considerable calcification and stenosis frequently occur in the radial artery (RA) in diabetic nephropathy. PTA was performed successfully using a balloon to expand and restrictively tear the longitudinal axis of the RA. This approach seems to be a useful measure of promoting the maturation of AVF in diabetic nephropathy.

Case report of penile cancer recurrence treated with cetuximab combined with anlotinib.

Penile squamous cell carcinoma with pelvic lymph node metastases/recurrence has a poor prognosis. We reported a case with recurrent pSCC was administered cetuximab and anlotinib after failure of first-line treatment and achieved an effective response. Cetuximab combined with anlotinib may be a new choice for relapsed pSCC.

Docosahexaenoic acid reduces hypoglycemia-induced neuronal necroptosis via the peroxisome proliferator-activated receptor γ/nuclear factor-κB pathway.

DHA has been shown to be neuroprotective and important to neurogenesis, but its role in HG-induced brain injury and the underlying mechanisms remain unknown. To elucidate the therapeutic effect of DHA, we established a mouse model with insulin-induced hypoglycemic brain injury and an in vitro model of HT-22 cells using a sugar-free medium. DHA treatment significantly reduced neuronal death and improved HG-induced learning and memory deficits.

Down-regulated miR-21 promotes learning-memory recovery after brain injury.

Background: MicroRNA is anendogenous non-coding single strand RNA which consists of 22 nt. It post-transcriptionally regulates gene expression and development. MicroRNA 21 plays an important role in repairing injured brain tissues.

Effect of insect tea on D-galactose-induced oxidation in mice and its mechanisms.

Insect tea is a traditional Chinese drink that contains abundant bioactive substances. In this study, the preventive effect of Insect tea on D-galactose-induced oxidation in mice was studied. The serum, liver, and spleen of mice were measured by biochemical and molecular biological methods, which showed that Insect tea could increase the biochemical indexes of the thymus, brain, heart, liver, spleen, and kidney in mice with induced oxidative damage.

Association of peroxisome proliferator-activated receptor-gamma gene polymorphisms and gene-gene interaction with asthma risk in a Chinese adults population.

Aims: To investigate the association between single nucleotide polymorphism (SNP) of peroxisome proliferator-activated receptors γ (PPAR γ) and additional gene-gene interactions on asthma risk.

Methods: A total of 882 subjects (602 males, 280 females), with a mean age of 61.3±14.

Anxiolytic effect of essential oils of Salvia miltiorrhiza in rats.

This study aims to investigate the anxiolytic effects of essential oil from S. miltiorrhiza in rats. The elevated plus maze test and the social interaction test were performed to evaluate the anxiolytic effects of essential oil.

Loss of expression of MHC class I-related chain A (MICA) is a frequent event and predicts poor survival in patients with hepatocellular carcinoma.

Natural killer (NK) cells are important effector cells for the first line of defense against tumor. Distant MHC class I homolog MICA has been identified as human ligand for NK cell activating receptor NKG2D. Engagement of MICA triggers NK cells and augments antigen-specific CTL anti-tumor immunity.
