The gut microbiota mediates memory impairment under high-altitude hypoxia via the gut-brain axis in mice.

Hypoxia is a predominant risk factor at high altitudes, and evidence suggests that high-altitude hypoxia alters the gut microbiota, which plays an essential regulatory role in memory function. However, the causal relationship between the gut microbiota and memory impairment under hypoxic conditions remains unclear. In this study, we employed a high-altitude hypoxia model combined with fecal microbiota transplantation (FMT) approach in mice to explore the effects of the gut microbiota on memory impairment in a hypoxic environment.

Analysis of risk factors associated with cervical HPV infection and their effects on female sexual function and anxiety: a multicenter cross-sectional study based on Chinese women.

Introduction: This research aimed to explore the determinants of cervical HPV infection and evaluate how cervical cancer screening outcomes influence sexual functioning and anxiety among women across three provinces in China.

Methods: Study participants were categorized into HPV-positive or HPV-negative groups, after which they completed the General Characteristics Questionnaire and the SAS Anxiety Scale. The HPV-positive cohort was further divided into four subgroups: Subgroup 1 consisted of individuals with HPV types 16 or 18 but no cytological abnormalities.

Investigating the molecular mechanism of vitexin targeting CDK1 to inhibit colon cancer cell proliferation via GEO chip data mining, computer simulation, and biological activity verification.

The objective of this study is to explore the antiproliferative activity of the traditional Chinese medicine monomer vitexin on colon cancer HCT-116 cells and its underlying mechanism. The in vitro antiproliferative activity of vitexin on colon cancer HCT-116 cells was evaluated using the CCK-8 assay. Potential drug targets for colon cancer were identified through GEO chip data mining, and molecular docking using Schrödinger software was conducted.

Prognostic value of inflammatory markers NLR, PLR, and LMR in gastric cancer patients treated with immune checkpoint inhibitors: a meta-analysis and systematic review.

Background: Immune checkpoint inhibitors (ICIs) represent a groundbreaking approach to cancer therapy. Inflammatory markers such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) have emerged as potential indicators strongly associated with tumor prognosis, albeit their prognostic significance remains contentious. The predictive value of NLR, PLR, LMR in patients with gastric cancer (GC) treated with ICIs has not been fully explored; therefore, we conducted a meta-analysis to examine the potential of inflammatory markers NLR, PLR, and LMR as survival predictors in this population.

Methods: In a retrospective study at the Affiliated Hospital of Shaanxi University of Traditional Chinese Medicine, 114 post-PCI ACS patients were analyzed from March 2021 to June 2023. Fifty-five underwent exercise rehabilitation (control group), while 59 received both acupuncture and exercise rehabilitation (joint group).

Clinical and hematological characteristics of children infected with the omicron variant of SARS-CoV-2: role of the combination of the neutrophil: lymphocyte ratio and eosinophil count in distinguishing severe COVID-19.

Purpose: Investigate the clinical/hematological characteristics of children infected with the Omicron variant of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) and identify an effective indicator to distinguish coronavirus disease 2019 (COVID-19) severity in children.

Methods: A retrospective study was conducted through electronic medical records from pediatric patients. The demographic, clinical, and routine blood test (RBT) features of children diagnosed by real-time PCR for SARS-CoV-2 were collected.

[Research progress on the mechanisms of probiotics promoting wound healing].

Slow wound healing has been a troublesome problem in clinic. In China, traditional methods such as antibiotics and silver sulfadiazine are used to treat skin wound, but the abuse use has many disadvantages, such as chronic wounds and pathogen resistance. Studies have shown that the microorganisms with symbiotic relationship with organisms have benefits on skin wound.

[Therapeutic effect and mechanism of piracetam for the treatment of spinal cord injury in rats through MAPK pathway].

Objective: To explore mechanism of piracetam for the treatment of spinal cord injury in rats through mitogen-activated protein kinase (MAPK) pathway.

Methods: Fifty-four healthy 6-week-old SD female rats with body weight of 80 to 100 g were divided into sham operation group, spinal cord injury group and piracetam group by random number table method, with 18 rats in each group. Spinal cord injury model was established in spinal cord injury group and piracetam group using percussion apparatus, while sham operation group did not damage spinal cord.

Microglial purinergic signaling in Alzheimer's disease.

Alzheimer's disease (AD) is a progressive and fatal neurodegenerative disease. The prevalent features of AD pathogenesis are the appearance of β-amyloid (Aβ) plaques and neurofibrillary tangles, which cause microglial activation, synaptic deficiency, and neuronal loss. Microglia accompanies AD pathological processes and is also linked to cognitive deficits.
