The release of metal elements from litter decomposition in forest ecosystems is crucial for material cycling and ecosystem health, but the impact of future variations in rainfall due to climatic fluctuations on this release is unknown. This study conducted an outdoor rainfall variability simulation and an in situ litter decomposition experiment in a subtropical location, with a focus on pure Pinus massoniana (PM) and 4 p.m.

- Limited nitrogen (N) and phosphorus (P) availability could restrict the ability of forests to store carbon in the 21st century, with mixed forests potentially improving productivity compared to pure coniferous forests.
- This research demonstrates how soil N, P, and plant species richness significantly influence soil organic carbon (SOC) stocks in Pinus massoniana mixed forests, with specific ratios of N to P affecting SOC accumulation in different soil depths.
- The findings suggest that while N and P limitations will impact SOC growth over the next 60 years, modifying the N:P ratio by changing plant species composition could mitigate these limitations, enhancing biomass and SOC stocks.
Article Synopsis
- This study investigates how variations in the CYP3A4 gene affect the levels and effectiveness of the epilepsy drug perampanel (PER) in Chinese children with epilepsy.
- 102 pediatric patients were analyzed after maintaining consistent PER doses for 21 days, measuring drug concentrations and assessing seizure reduction rates.
- The results indicate significant differences in drug concentrations based on genetic variations, with implications for both treatment efficacy and adverse effects, suggesting that CYP3A4 genetic profiles should be considered in prescribing PER.
Purpose: This study was the first to evaluate the effect of CYP3A5*3 gene polymorphisms on plasma concentration of perampanel (PER) in Chinese pediatric patients with epilepsy.
Methods: We enrolled 98 patients for this investigation. Plasma PER concentrations were measured using liquid chromatography-tandem mass spectrometry.
Background: Information on the efficacy and plasma concentration of perampanel (PER) in Chinese pediatric patients with epilepsy is limited. Therefore, this real-world retrospective study aimed to assess the efficacy, tolerability, and plasma concentration of the maximum dose of PER for epilepsy treatment in Chinese pediatric patients.
Methods: A total of 107 pediatric patients from 2 hospitals in China were enrolled in this study.
The safety and effectiveness of perampanel in clinical settings involving Chinese pediatric patients are limited, as perampanel has only recently been approved for use in China, in September 2019. We aimed to evaluate the efficacy and tolerability of perampanel as an adjunctive therapy for pediatric patients with epilepsy aged ≥ 4 years in Xinjiang, Northwest China. Efficacy was assessed by measuring changes in seizure frequency at 3-, 6-, and 12-month follow-up compared with baseline.

Objective: To investigate the development of social skills in children with autism spectrum disorder (ASD) and related influencing factors.
Methods: A total of 889 children with ASD in 10 cities of China were enrolled as subjects. The Autism Social Skills Scale was used to assess their social skills.
