Taxifolin ameliorates the D-galactose-induced aging of mouse hippocampal neurons HT-22 cells through modulating SIRT1/p53 and PI3K/AKT signaling pathways.

By establishing an model of D-Gal-induced brain neuronal cell (HT-22) senescence, it was found that TAX treatment significantly increased the activities of SOD and GSH, while decreasing MDA levels in aging HT-22 cells, indicating that TAX effectively restored the total antioxidant capacity and antioxidant enzyme activity of aging HT-22 cells induced by D-Gal, and attenuated cellular oxidative stress injury. In addition, taxifolin could also protect HT-22 cells from aging by up-regulating SIRT1 while reducing the expression of Ac-p53, indicating that TAX may be an active substance that can effectively delay cell aging.

A brief history of clozapine in China with a look forward.

Clozapine was first manufactured in China in 1976. Clozapine is currently used not only for treatment-refractory schizophrenia (TRS), but also continues to be used in the treatment of patients with non-TRS and other mental disorders; moreover, low-dose clozapine is also used in sedative-hypnotic therapy and in combination with other drugs. There is need for studies in China using various titrations and assessing their risk for myocarditis and aspiration pneumonia.

Published population pharmacokinetic models of valproic acid in adult patients: a systematic review and external validation in a Chinese sample of inpatients with bipolar disorder.

Background: This study reviewed all published valproic acid (VPA) population pharmacokinetic (PPK) models in adult patients and assessed them using external validation methods to determine predictive performance.

Methods: Thirteen published PPK models (labeled with letters A to M) not restricted to children were identified in PubMed, Embase, and Web of Science databases. They were evaluated in a sample totaling 411 serum concentrations from 146 adult inpatients diagnosed with bipolar disorder in a Chinese hospital.

Efficacy and safety of aripiprazole once-monthly versus oral aripiprazole in Chinese patients with acute schizophrenia: a multicenter, randomized, double-blind, non-inferiority study.

Objective: The present study aimed to evaluate the efficacy and safety of aripiprazole once-monthly (AOM) compared to oral aripiprazole in treating acute schizophrenia.

Methods: This randomized, double-blind, non-inferiority study recruited patients from 15 trial sites across China from May 2017 to April 2019. Patients with an acute psychotic episode received AOM at 400 mg or oral aripiprazole at 10-20 mg for 12 weeks.

The Impact of Smoking, Sex, Infection, and Comedication Administration on Oral Olanzapine: A Population Pharmacokinetic Model in Chinese Psychiatric Patients.

Unlabelled: BACKGROUND AND OBJECTIVE: Prior olanzapine population pharmacokinetic (PPK) models have focused on the effects of sex and smoking on olanzapine clearance. This PPK model in Chinese adult psychiatric patients also investigated the influence of comedications and co-occurrence of infections on olanzapine clearance, and explored how to personalize oral olanzapine dosage in the clinical setting.

Methods: A total of 1546 serum concentrations from 354 patients were collected in this study.

Clinical features of patients with anti-leucine-rich glioma inactivated-1 protein associated encephalitis: a Chinese case series.

Antibodies against leucine-rich glioma inactivated 1 (LGI1) are associated with limbic encephalitis and faciobrachial dystonic seizures (FBDS). We present a large series of Han Chinese patients for further clinical refinement. Serum and cerebrospinal fluid samples from patients were tested.

Effect of childhood trauma on cognitive functions in a sample of Chinese patients with schizophrenia.

In this study, we aimed to determine the influence of various types of childhood trauma (CT) on cognitive functions in Chinese patients presented with schizophrenia. One hundred sixty-two patients were assessed with the Childhood Trauma Questionnaire-Short Form (CTQ-SF) and Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). We investigated the correlations between various types of CT, demographic characteristics, and cognitive functions.

[Using the cumulative odds Logit model to explore the application of the questionnaire derived from PANSS].

Currently, aripiprazole, olanzapine and risperidone are three anti-psychiatry agents commonly used in the treatment of schizophrenia. Although the efficacy of these drugs is good, schizophrenia cannot be completely cured yet. Patients need long-term medication.

Extrapyramidal Symptoms During Risperidone Maintenance Treatment in Schizophrenia: A Prospective, Multicenter Study.

The risperidone maintenance treatment in schizophrenia study was designed to identify the duration of maintenance treatment required with an initial therapeutic dose in contrast to reducing the dose over time. This study investigated extrapyramidal symptoms (EPSs) in different risperidone maintenance treatment paradigms over 1 year. Clinically stabilized patients with schizophrenia (n = 374) were randomized to a no-dose-reduction group and 4-week and 26-week reduction groups, in which the dose was gradually reduced by 50% over 8 weeks and maintained.

Single- and Multiple-Dose Milnacipran Pharmacokinetics in Healthy Han Chinese Volunteers.

Background: The pharmacokinetics of milnacipran have been studied in Caucasian subjects but not in Chinese subjects.

Methods: This single-center, open-label study evaluated the pharmacokinetics and safety of oral milnacipran administered as a randomized, three-way crossover, single-dose (25, 50 and 100 mg) and in multiple doses for 8 days (up to 100 mg/day administered as 50 mg twice daily) in Han Chinese healthy volunteers. Both the single- and multiple-dose studies included 12 different adults (six males and six females), respectively.

In vivo USPIO-enhanced MR signal characteristics of secondary degeneration in the ipsilateral substantia nigra after middle cerebral artery occlusion at 3T.

Background And Purpose: Ultrasmall superparamagnetic iron oxide (USPIO) particles to enhance MRI have been used to study neuroinflammation in vivo. Our purpose was to observe the USPIO-enhanced MR signal alterations in the primary ischemic lesion and ipsilateral substantia nigra after middle cerebral artery occlusion (MCAO) to verify the subsequent sequelae of neuroinflammation seen in the primary ischemic focus and secondary degeneration region.

Materials And Methods: Sprague-Dawley rats were subjected to transient MCAO.

Population pharmacokinetics of clozapine and its primary metabolite norclozapine in Chinese patients with schizophrenia.

Aim: To develop a combined population pharmacokinetic model (PPK) to assess the magnitude and variability of exposure to both clozapine and its primary metabolite norclozapine in Chinese patients with refractory schizophrenia via sparse sampling with a focus on the effects of covariates on the pharmacokinetic parameters.

Methods: Relevant patient concentration data (eg, demographic data, medication history, dosage regimen, time of last dose, sampling time, concentrations of clozapine and norclozapine, etc) were collected using a standardized data collection form. The demographic characteristics of the patients, including sex, age, weight, body surface area, smoking status, and information on concomitant medications as well as biochemical and hematological test results were recorded.
