Evaluating the impact of COVID-19 outbreak on hepatitis B and forecasting the epidemiological trend in mainland China: a causal analysis.

Background: It is uncertain how COVID-19 outbreak influences the hepatitis B epidemics. This study aims to evaluate the effects on hepatitis B owing to the COVID-19 outbreak and forecast the hepatitis B epidemiological trend in mainland China to speed up the course of the "End viral hepatitis Strategy".

Methods: We estimated the causal impacts and created a forecast through adopting monthly notifications of hepatitis B each year from 2005 to 2020 in mainland China using the Bayesian structural time series (BSTS) method.

Design, Preparation, and Mechanical Property Study of Polylactic Acid/CaBOCl: Eu, Dy Composite Material for 3D Printing.

To break through the simplification of three-dimensional printing (3DP) materials and realize the application of long-persistent phosphors in more fields, polylactic acid doped with CaBOCl: Eu, Dy was prepared in this study. The structure of the mixtures was analyzed and determined by infrared spectroscopy. The luminescence properties of phosphors and the composites were studied by fluorescence spectra and afterglow decay curve measurements.

Predictors for quality of life in older adults: network analysis on cognitive and neuropsychiatric symptoms.

Background: Quality of life (QoL) of older adults has become a pivotal concern of the public and health system. Previous studies found that both cognitive decline and neuropsychiatric symptoms (NPS) can affect QoL in older adults. However, it remains unclear how these symptoms are related to each other and impact on QoL.

Quantitation of levetiracetam concentrations in plasma and saliva samples by ultra-performance liquid chromatography-tandem mass spectrometry: Application to therapeutic drug monitoring for pregnant women with epilepsy.

Although levetiracetam (LEV) has favorable linear pharmacokinetic properties, therapeutic drug monitoring (TDM) is necessary for pregnant women with epilepsy. This study aims to build a simple, reliable, and sensitive ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method for determining LEV concentrations in plasma and saliva samples, to support the routine TDM of LEV in Chinese pregnant women with epilepsy. The stable isotope-labeled LEV-d was used as the internal standard.

Dietary xanthophyll improved growth, antioxidant, pigmentation and meat quality in the southern catfish ( Chen).

Xanthophyll has multiple physiological functions to improve the quality of farmed animals. The present study aimed to investigate the effects of xanthophyll on the growth performance, antioxidation, immunity, pigmentation and meat quality of southern catfish ( Chen). Juvenile southern catfish (18.

The pharmacokinetics and safety of lidocaine in liver cancer patients undergoing hepatic resection.

Purpose: The purpose of this study was to explore the pharmacokinetics (PK) characteristics and safety of continuous lidocaine infusion during hepatectomy in liver cancer patients.

Methods: This study included thirty-five patients undergoing laparoscopic hepatectomy from January 2021 to December 2021. Patients received a short infusion of 1% lidocaine at a dose of 1.

The Association between Spicy Food Consumption and Psychological Health in Chinese College Students: A Cross-Sectional Study.

Background: Capsaicin is the main active ingredient in chili peppers and spicy food. Animal studies provide contradictory results on the role of capsaicin in psychiatric disorders. There are no epidemiological studies to investigate the relationship between spicy food consumption and psychological health.

Muscle Nutritive Metabolism Changes after Dietary Fishmeal Replaced by Cottonseed Meal in Golden Pompano ().

Our previous study demonstrated that based on growth performance and feed utilization, cottonseed meal (CSM) could substitute 20% fishmeal (FM) without adverse effect on golden pompano (). Muscle deposition was also an important indicator to evaluate the efficiency of alternative protein sources. Therefore, the present study was conducted to explore the changes of physiobiochemical and nutrient metabolism in muscle after FM replaced by CSM.

Simultaneous determination of lidocaine and its active metabolites in plasma by UPLC-MS/MS and application to a clinical pharmacokinetic study in liver cancer patients with laparoscopic hepatectomy.

Lidocaine, widely used as a local anesthetic, has anti-inflammatory and inhibitory effects on tumor recurrence and metastasis. To investigate the pharmacokinetics of lidocaine in liver cancer patients undergoing laparoscopic hepatectomy, a fast and sensitive analytical technique was developed. The method was adequately validated with ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) to simultaneously determine the concentration of lidocaine and its metabolites in plasma.
