Brain structures as potential mediators of the causal effect of COVID 19 on migraine risk.

Migraine is a common neurological disorder observed after coronavirus disease 2019 (COVID 19) infection. However, the intricate relationship between COVID 19 and migraine, particularly the potential mediating role of brain imaging-derived phenotypes (BIPs), remains unclear. This study used linkage disequilibrium score regression (LDSC), a bidirectional two-sample Mendelian randomization (MR) approach, and two-step MR analysis to investigate potential causal links.

Internet of things-based management versus standard management of home noninvasive ventilation in COPD patients with hypercapnic chronic respiratory failure: a multicentre randomized controlled non-inferiority trial.

Background: Effective monitoring and management are crucial during long-term home noninvasive positive pressure ventilation (NPPV) in patients with hypercapnic chronic obstructive pulmonary disease (COPD). This study investigated the benefit of Internet of Things (IOT)-based management of home NPPV.

Methods: This multicenter, prospective, parallel-group, randomized controlled non-inferiority trial enrolled patients requiring long-term home NPPV for hypercapnic COPD.

Observation of Bleeding and MACCE Events in Patients with Liver Cirrhosis Complicated with Acute Coronary Syndrome after Antiplatelet Therapy.

Objective: To evaluate the efficacy and safety of dual antiplatelet therapy (DATP) in subjects with Child-pugh class A cirrhosis complicated with acute coronary syndrome (ACS) after coronary Drug-eluting stent (DES) implantation.

Study Design: Observational study. Place and Duration of the Study: Department of Cardiology, Beijing You 'an Hospital, Capital Medical University, China, from January to August 2021.

Lactobacillus plantarum-derived extracellular vesicles protect against ischemic brain injury via the microRNA-101a-3p/c-Fos/TGF-β axis.

Currently, the reported source of extracellular vesicles (EVs) for the treatment of ischemic stroke（IS）is limited to mammals. Moreover, these EVs are restricted to clinical translation by the high cost of cell culture. In this respect, Lactobacillus plantarum culture is advantaged by low cost and high yield.

Mir-184 Contributes to Brain Injury Through Targeting PPAP2B Following Ischemic Stroke in Male Rats.

Our previous study revealed that miR-184 expression is significantly altered in the brain following ischemic stroke in rats. However, it is unknown whether this alteration in miR-184 expression contributes to brain injury after ischemic stroke. Here, we aim to address the potential of miR-184 to impact nerve injury following ischemia and reperfusion.

[Study on natural killer cell subset and activity in patients with depression].

Objective: The study was to investigate natural killer cells subset and activity in patients with depression.

Methods: 46 outpatients with unipolar depression and 46 normal controls were recruited. Peripheral blood samples were drawn for natural killer cells subset and activity.
