Article Synopsis
  • Olanzapine is an atypical antipsychotic used for mental disorders, but there's limited pharmacokinetic data for Chinese pediatric patients aged 10 to 17 years, which raises questions about dosage variability.
  • A study collected therapeutic drug monitoring data from 151 pediatric patients and developed a model using NONMEM software to simulate dosing regimens, targeting a concentration level of 20 ng/ml.
  • The final model identified sex and concomitant valproate as significant factors affecting olanzapine clearance, suggesting specific daily dosages for male and female patients, which can assist physicians in dosage adjustments.

Objectives: The aim of this study was to investigate risk factors and psychological stress of health-care workers (HCWs) with coronavirus disease 2019 (COVID-19) in a nonfrontline clinical department.

Methods: Data of 2 source patients and all HCWs with infection risk were obtained in a department in Wuhan from January to February 2020. A questionnaire was designed to evaluate psychological stress of COVID-19 on HCWs.

Purpose: This study aimed to investigate the influence of diagnosis, body weight, sex, age, smoking, formulations, and concomitant drugs on steady-state dose-corrected serum concentrations (C/D) of venlafaxine (VEN) and O-desmethylvenlafaxine (ODV).

Methods: A retrospective analysis of therapeutic drug monitoring (TDM) was carried out. Patients' demographic data, therapeutic regimens, and concentrations were collected.

Background: The objective of this study was to investigate the serum concentrations of olanzapine in relation to age, sex, and other factors in Chinese patients aged between 10 and 90 years.

Methods: Data for 884 olanzapine patients, deposited between 2016 and 2017, were retrieved from the therapeutic drug monitoring database of the Affiliated Brain Hospital of Guangzhou Medical University. The effects of covariates on serum olanzapine concentration, dose-normalized concentration (C/D ratio), and normalized concentration (C/D/weight) were investigated.

Lamotrigine (LTG) is a second-generation anti-epileptic drug widely used for focal and generalized seizures in adults and children, and as a first-line medication in pregnant women and women of childbearing age. However, LTG pharmacokinetics shows high inter-individual variability, thus potentially leading to therapeutic failure or side effects in patients. This prospective study aimed to establish a population pharmacokinetics model for LTG in Chinese patients with epilepsy and to investigate the effects of genetic variants in uridine diphosphate glucuronosyltransferase (UGT) 1A4, UGT2B7, MDR1, ABCG2, ABCC2, and SLC22A1, as well as non-genetic factors, on LTG pharmacokinetics.

Morroniside, an iridoid glycoside extracted from Cornus officinalis, has multiple pharmacological effects such as neuroprotection. This study took the lead in establishing a method for determining morroniside concentration in rat plasma by high performance liquid chromatography-tandem mass spectrometry. Plasma samples were processed with protein precipitation method, with hyperoside as the internal standard.

Objective: To prepare curcumin polybutylcyanoacrylate nanoparticles (Cur-PBCNs) and evaluate its characteristics.

Methods: Cur-PBCNs were prepared by emulsion polymerization, and the formulation was optimized by L16 (4(3)) orthogonal design test with entrapment efficiency and drug loading as indices. In addition, its characteristics were investigated.

AIM:To study the mechanism of Fuzhenghuayu (FZHY) decoction on anti-liver fibrosis.METHODS:FZHY 10% decoction sera was incubated with rat normal subcultured hepatic stellate cells (HSC) and fibrotic primarily cultured HSC, normal and fibrotic hepatocytes and subcultured skin fibroblasts seperately. Cell intracellular and extracellular collagen synthesis rates were measured by the method of (3)H Proline impulse and collagenase digestion.
