[Evaluation of Annual Straw Return Based on Soil Carbon Pool and Crop Yield in Wheat-maize Cropping System].

The treatment and recycling of crop straws has become a hot spot in the field of agricultural research, with the need to optimize the management of wheat-maize annual straws, improve the carbon efficiency of cropping systems, and promote the sustainable production of wheat-maize annual straw. Based on an 8-year long-term field trial, two treatments, wheat-maize double cropping （WS-MS） and wheat-maize single cropping （WS-MN）, were set up, and the effects of straw returning on soil organic carbon （TOC） content, oxidizable organic carbon （EOOC） content, soil carbon storage, carbon pool management index （CPMI）, carbon use efficiency, and crop yield were compared between WS-MS and WS-MN treatments. The results showed that the content of TOC in WS-MS and WS-MN increased by 8.

[Effect of No-tillage on Soil Aggregates in Farmland：A Meta Analysis].

In order to clarify the impact of no-tillage on the quality of farmland soil aggregates in China and promote the adaptive application of no-tillage practices， a Meta-analysis was conducted by collecting data from 116 published studies. The effects of no-tillage on aggregate size distribution， mean weight diameter （MWD）， and aggregate-associated C were studied. The results showed that compared with that under tillage， no-tillage significantly increased the proportion of macroaggregates （10.

[Effect of Biochar on Agricultural Soil Aggregates and Organic Carbon: A Meta-analysis].

As a soil amendment, biochar has been widely used to ameliorate agricultural soil. To ensure the effect of biochar on the carbon sequestration of farmlands in China, a Meta-analysis was carried out via collecting published literatures. We quantitatively analyzed the response of biochar application to soil aggregates, aggregate carbon, and soil organic carbon to different experimental conditions.

[Optimizing Straw Management to Enhance Carbon and Nitrogen Efficiency and Economic Benefit of Wheat-Maize Double Cropping System].

The optimization of annual straw management can improve the yield, income, and carbon and nitrogen efficiency of wheat-maize double cropping systems. Based on a long-term positioning trial started in 2012, five straw management methods were considered, C100 (100% return), C75 (75% return+25% harvest), C50 (50% return+50% harvest), C25 (25% return+75% harvest), and C0 (100% harvest). We analyzed the effects of farmland carbon and nitrogen inputs and their ratios on crop yield, carbon and nitrogen use efficiency, and economic benefits in wheat and maize anniversaries with different straw managements.

Effects of traditional Chinese medicine on intestinal mucosal permeability in early phase of severe acute pancreatitis.

Background: Traditional Chinese medicine has been used widely for many years in China to treat acute pancreatitis. We have investigated the effects of Dachengqi decoction on intestinal mucosal permeability and outcome in patients with severe acute pancreatitis (SAP).

Methods: Forty patients with sustained SAP that required admission to the surgical intensive care unit were enrolled prospectively in the study.

Tenuigenin protects cultured hippocampal neurons against methylglyoxal-induced neurotoxicity.

Methylglyoxal is a metabolite of glucose. Since serum methylglyoxal level is increased in diabetic patients, methylglyoxal is implicated in diabetic complications such as cognitive impairment. This study aimed to evaluate the effects of tenuigenin, an active component of roots of Polygala tenuifolia Willdenow, on methylglyoxal-induced cell injury in a primary culture of rat hippocampal neurons.

[Soil nutrient leaching patterns in maize field under different fertilizations: an in situ study].

An in situ field experiment with lysimeter was conducted to study the effects of different fertilizations on the nutrient leaching loss from brown soil in the growth season of summer maize. The results showed that abundant rainfall and irrigation were the main factors affecting the leaching loss. The leaching amount was higher in the early growth period of summer maize, but decreased after then.

[Effect of dongchong xiacao capsule on airway inflammation of asthmatic patients].

Objective: To investigate the effect of dongchong xiacao capsule on the airway inflammation of asthmatic patients and to explore the relevant mechanism of therapeutic effect of Dongchongxiacao capsule.

Method: Sixty patients with moderate persistent asthma were randomized into the treatment group (n=30) and the control group (n=30). Inhaled corticosteroid and as-needed beta-agonist were used in the treatment group while this therapy plus dongchong xiacao capsule were used in the control group for two months.
