A two-stage ensemble learning based prediction and grading model for PD-1/PD-L1 inhibitor-related cardiac adverse events: A multicenter retrospective study.

Background: Immune-related cardiac adverse events (ircAEs) caused by programmed cell death protein-1 (PD-1) and programmed death-ligand-1 (PD-L1) inhibitors can lead to fulminant and even fatal consequences. This study aims to develop a prediction and grading model for ircAEs, enabling graded management of patients.

Methods: This study utilized medical record systems from two medical institutions to develop a prediction and grading model for ircAEs using ten machine learning algorithms and two variable screening methods.

YouTube as a source of information for cryptococcal infection: A cross-sectional study.

Objective: Immunocompromised individuals, particularly HIV patients, worldwide are at risk from cryptococcal infection. There are a number of videos of cryptococcal infection and more and more individuals may search these videos, but the quality of videos on YouTube is unclear. This study set out to assess the content and quality of YouTube videos regarding cryptococcal infection.

miR-181a targets PTEN to mediate the neuronal injury caused by oxygen-glucose deprivation and reoxygenation.

Evidence suggests that the microRNA-181 (miR-181) family performs various roles in the pathophysiology of cerebral ischemia and reperfusion injury (CIRI). MiR-181a has been identified as a critical determinant of neuronal survival. Moreover, the significance of miR-181a in controlling neuronal death after CIRI has received little attention.

Direct targeting of DOCK4 by miRNA-181d in oxygen-glucose deprivation/reoxygenation-mediated neuronal injury.

The miRNA-181 (miR-181) family regulates neuronal persistence during cerebral ischemia/reperfusion injury (CI/RI). Since the effect of miR-181d on CI/RI has never been studied, the current work sought to determine the involvement of miR-181d in neuronal apoptosis after brain I/R injury. To replicate in vivo and in vitro CI/RI, a transient middle cerebral artery occlusion (tMCAO) model in rats and an oxygen-glucose deficiency/reoxygenation (OGD/R) model in neuro 2A cells were developed.

Effect of folic acid supplementation on diminished ovarian reserve: study protocol of a single-centre, open-label, randomised, placebo-controlled clinical trial.

Introduction: The prevalence of diminished ovarian reserve (DOR), a common gynaecological disorder, is approximately 10% across the world. Failure in early diagnosis and treatment may result in continuous decreases in ovarian function and the resultant loss in an opportunity of pregnancy, which greatly affects the happiness of the women's family and women's physical and mental health. Nevertheless, there has been no effective treatment for such a disorder until now.

Polymorphisms of Calgranulin Genes and Ischemic Stroke in a Chinese Population.

Background: The S100/calgranulin gene appears to modulate neuroinflammation following cerebral ischemia and could be a valuable biomarker for stroke prognosis, according to growing research. This study aimed at evaluating the correlation between calgranulin gene variants and susceptibility to ischemic stroke (IS) in the Southern Chinese population.

Methods: Using an enhanced multi-temperature ligase detection reaction genotyping, 310 IS patients and 324 age-matched healthy controls were genotyped to identify five calgranulin gene variants.

Application Effects of SBAR Communication Mode in ICU Nursing Physical Restraint Shift.

Context: Correct and effective handovers of patients' information during shift changes can ensure patients' safety and can help an incoming shift of nurses to continuously monitor patients' psychological problems and avoid unnecessary physical restraints. Development of a standard procedure for handover of patients who have been physically restrained has important clinical significance related to the smooth continuation of nursing work and assurance of the quality of care.

Objective: The study intended to investigate the clinical effects of the situation-background-assessment-recommendation (SBAR) communication mode on the quality of the information passed during shift changes about patients in intensive care units (ICUs) who had been physically restrained and to compare it to the clinical effects obtained using traditional methods of communication.

Correlation Between Angiotensin Receptor Type 1 Polymorphisms and Atherosclerotic Cerebral Infarction Risk.

Background: Emerging evidences suggest that the angiotensin receptor type 1 (AT1R) contributes heavily to the pathogenesis of atherosclerotic cerebral infarction (ACI). Herein, we examined a potential link between AT1R gene polymorphisms and ACI risk among a Southern Han Chinese population.

Methods: The rs3772616, rs275645, and rs377262 AT1R polymorphisms were genotyped in 689 ACI patients and 712 healthy controls, using the iMLDR-TM assay.

Genetic Variants of Contribute to Susceptibility of Ischemic Stroke among Southern Chinese Population.

Emerging evidence suggests that the long noncoding RNA (lncRNA) growth arrest special 5 (GAS5) plays crucial roles in the pathogenesis of ischemic stroke (IS). The current research is aimed at assessing the correlation between two functional variants (rs145204276 and rs55829688) and susceptibility to IS in a Han Chinese population. This study genotyped the two variants in 1086 IS patients as well as 1045 age-matched healthy controls by using an improved multitemperature ligase detection reaction (iMLDR-TM) genotyping technology.

Synthesis of carbon black/carbon nitride intercalation compound composite for efficient hydrogen production.

The photoactivity of g-C3N4 is greatly limited by its high recombination rate of photogenerated carriers. Coupling g-C3N4 with other materials has been demonstrated to be an effective way to facilitate the separation and transport of charge carriers. Herein we report a composite of conductive carbon black and carbon nitride intercalation compound synthesized through facile one-step molten salt method.

Regulation of enzyme activity through interactions with nanoparticles.

The structure and function of an enzyme can be altered by nanoparticles (NPs). The interaction between enzyme and NPs is governed by the key properties of NPs, such as structure, size, surface chemistry, charge and surface shape. Recent representative studies on the NP-enzyme interactions and the regulation of enzyme activity by NPs with different size, composition and surface modification are reviewed.
