[Response of Topsoil Fungal Community Structure to Soil Improvement Measures in Degraded Forest of Red Soil Region].

Soil fungal community structure and diversity are highly sensitive to variations in the external environment, as well as soil improvement measures. In order to clarify the effects of soil improvement measures on topsoil fertility or quality, a field experiment was conducted in eroded forest of a red soil region. Organic fertilizer, biochar, and lime+microbial fertilizer were added to the topsoil, respectively.

[Accumulation Characteristics and Release Regularity of Nutrients in Sediments of a Surface-flow Constructed Wetland After Long-term Operation].

Sediments serve as an important carrier during the migration and transformation of pollutants in surface-flow constructed wetlands. Exploring the accumulation characteristics and release patterns of nutrients is of great significance for assessing the purification functions of constructed wetlands after long-term operation. The contents of total organic carbon (TOC), total nitrogen (TN), and total phosphorus (TP) in sediments at various locations of the 5-year-old Yanlong Lake surface-flow constructed wetland were analyzed and static release experiments with cylindrical core samples were carried out.

Assessment of drug-drug interactions between voriconazole and glucocorticoids.

Voriconazole is used to treat fungal infections in patients receiving glucocorticoid therapy in clinic. The objective of this study was to characterize the potential drug-drug interactions (DDIs) between voriconazole and glucocorticoids using physiologically based pharmacokinetic (PBPK) models. Voriconazole and glucocorticoids PBPK models were constructed by using physicochemical data and pharmacokinetic parameters in healthy subjects, and verified by comparing the predicted pharmacokinetic parameters with corresponding data acquired from published literatures.

The Effects of TiO2 Nanodot Films with RGD Immobilization on Light-Induced Cell Sheet Technology.

Cell sheet technology is a new strategy in tissue engineering which could be possible to implant into the body without a scaffold. In order to get an integrated cell sheet, a light-induced method via UV365 is used for cell sheet detachment from culture dishes. In this study, we investigated the possibility of cell detachment and growth efficiency on TiO2 nanodot films with RGD immobilization on light-induced cell sheet technology.

Population Pharmacokinetics of Rifampicin in Chinese Patients With Pulmonary Tuberculosis.

Rifampicin (RIF) induces cytochrome P450, which in turn catalyzes drug metabolism; however, pharmacokinetic studies on this phenomenon in the Chinese population, especially in the context of disease, are limited. Therefore, we sought to establish population-based pharmacokinetic models of RIF in a Chinese population with pulmonary tuberculosis (TB). Clinical data were retrospectively collected from 54 patients with pulmonary TB and analyzed alongside RIF blood levels from 95 samples collected prior to RIF administration and between 2 and 12 hours after treatment.

Posterior reversible encephalopathy syndrome and graft-versus-host disease after liver transplantation: a case report and review of the literature.

Case (description): A 52-year-old male patient presented with seizures on the 16th day post liver transplantation suggesting tacrolimus-associated posterior reversible encephalopathy syndrome (PRES). On the 18th day, the patient was diagnosed with graft-versus-host disease (GVHD). Calcineurin inhibitor (CNI) was stopped and the patient received 1 g methylprednisolone and 25 g immunoglobulin.

Effects of CYP3A5 genotypes, ABCB1 C3435T and G2677T/A polymorphism on pharmacokinetics of Tacrolimus in Chinese adult liver transplant patients.

1. The purpose of this study was to establish a population pharmacokinetic (PK) model of tacrolimus and evaluate the influence of clinical covariates, including the genetic polymorphisms of the cytochrome P450 3A5 gene (CYP3A5) and gene-encoding P-glycoprotein (ABCB1), on the PK parameters in Chinese adult liver transplant recipients. 2.

Prediction of Pharmacokinetics and Penetration of Moxifloxacin in Human with Intra-Abdominal Infection Based on Extrapolated PBPK Model.

The aim of this study is to develop a physiologically based pharmacokinetic (PBPK) model in intra-abdominal infected rats, and extrapolate it to human to predict moxifloxacin pharmacokinetics profiles in various tissues in intra-abdominal infected human. 12 male rats with intra-abdominal infections, induced by Escherichia coli, received a single dose of 40 mg/kg body weight of moxifloxacin. Blood plasma was collected at 5, 10, 20, 30, 60, 120, 240, 480, 1440 min after drug injection.

Population pharmacokinetic analysis of tacrolimus early after Chinese pediatric liver transplantation.

Objective: The purpose of this study was to describe the population pharmacokinetics (PK) of tacrolimus (TAC) in 52 Chinese pediatric patients early after liver transplantation.

Methods: Details of drug dose, sampling times and concentrations were collected retrospectively from routine therapeutic drug monitoring data from the first day after surgery. A total of 488 concentration data were obtained and analyzed by a nonlinear mixed-effect modeling (NONMEM) method.

Population pharmacokinetics of intravenous levofloxacin 500 mg/day dosage in infected patients.

The purpose of this study was to explore the population pharmacokinetic features of levofloxacin in Chinese infected patients. A total of 27 Chinese adult infected patients were treated with intravenous levofloxacin (500 mg/day). In total, 49 plasma samples of levofloxacin were collected immediately after intravenous dripping and before administration on the 3rd, 4th or 5th day.

[Relationship between hMSH2 and FHIT gene expression in non-small cell lung cancer].

Background & Objective: Abnormality of FHIT gene has been proved to be frequent in certain malignant tumors closely related to environmental oncogenic factors, such as lung cancer. Foreign scholars have begun to explore the relationship between FHIT gene and other tumor suppressor genes, which are implicated in the pathogenesis of lung cancer. This study was designed to investigate the relationship between hMSH(2) and FHIT protein expression and to explore the correlation of hMSH(2) and FHIT protein expression with clinicopathologic features of lung cancer.
