Increased expression of plasma mir-9-3p and let-7b-3p in methamphetamine use disorder and its clinical significance.

Methamphetamine use disorder has emerged as a significant public health concern globally. This study endeavors to elucidate the alterations in expression changes of miRNAs in the plasma of methamphetamine use disorder and elucidate the alterations in miRNA expression in the plasma of individuals with methamphetamine use disorder and investigate the relationship between these differentially expressed miRNAs and the disorder itself, cravings for methamphetamine, and associated mental disorders. Furthermore, the study seeks to clarify the expression of downstream target molecules of specific miRNAs in the plasma of methamphetamine use disorder, assess the diagnostic utility of these miRNAs and their target molecules, explore their potential as biomarkers, and identify potential targets for the diagnosis and treatment of methamphetamine use disorder.

Clinical and Airway Inflammation Features of COPD Patients with Positive Bronchodilator Test.

Objective: To explore the difference in clinical characteristics and airway inflammation in chronic obstructive pulmonary disease (COPD) patients on the positive bronchodilator tests.

Study Design: Descriptive study.

Place And Duration Of Study: Affiliated Hospital of Shaoxing University, Shaoxing, China, from January to December 2017.

Synthesis of novel sonocatalyst Er:YAlO/NbO and its application for sonocatalytic degradation of methamphetamine hydrochloride.

The composited sonocatalyst Er:YAlO/NbO was prepared by ultrasonic dispersion and high temperature calcinations method. The microstructure of Er:YAlO was prepared via sol-gel method and NbO was prepared by hydrothermal method. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectrometer (EDX), ultraviolet-visible (UV-vis) spectra and photoluminescence (PL) spectra, respectively.
