[Bioinformatics database and production layout visual analysis platform of medicinal plants:a case study of Dao-di medicinal materials in Sichuan province].

In the new stage of trans-omics and trans-subjects for medicinal plants, it is an urgent need to integrate big data, provide interactive applications, and form a unified and multi-level research system and big data platform. Dao-di medicinal material, as an important source of medicinal plants, is a unique quality concept and comprehensive standard of tranditional Chinese medicine(TCM). Several databases have been developed in China and abroad, such as the Encyclopedia of Traditional Chinese Medicine(ETCM) and the Global Pharmacopoeia Genome Database(GPGD).

[Sources and Characteristics of Regional Background PM in North China During the Autumn and Winter Polluted Period].

The campaign of investigating the chemical compositions and particle size distributions of NR-PM(non-refractory PM) was conducted by using a High Resolution Time of Flight Aerosol Mass Spectrometer(HR-ToF-AMS) at the Shangdianzi(SDZ) regional atmospheric background site(117.07°E, 40.39°N), northeast of Beijing, from October 17 2015 to January 27 2016.

The evolution of optimal resource allocation and mating systems in hermaphroditic perennial plants.

By incorporating the effects of inbreeding depression (ID) on both juveniles and adults survivorship, we developed a new theoretical model for hermaphroditic perennial plants. Our model showed that the effect of the selfing rate on the evolutionarily stable strategy (ESS) reproductive allocation depends on three parameters: (1) the self-fertilized juvenile relative survivorship (SFJRS), (2) the self-fertilized adult relative survivorship (SFARS) and (3) the growth rate of self-fertilized adult, where the SFJRS is the survivorship of self-fertilized juveniles divided by the survivorship of outcrossed juveniles, and likewise for the SFARS. However, the ESS sex allocation decreases as the selfing rate increases.

[Study of the change and role of protein C system in ulcerate colitis].

Hypercoagulable state and thrombosis are major lethal causes of ulcerate colitis (UC). The aim of the present study is to explore the change and role of protein C (PC) system in UC thrombosis. 4% dextran sulfate sodium (DSS) was used to induce the UC model, and the body weight, the length of colon, and the weight of spleen were measured after intake of DSS as drinking water for 1 week.

[Apocynin relieves inflammation in dextran sulfate sodium-induced ulcerative colitis mice: the role of NOXs-ROS-p38MAPK pathway].

The study is aimed to explore the molecular mechanism of the treatment of apocynin in dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) mice. 5% DSS was used to mimic the UC model, and 2% apocynin was applied to treat the UC mice. HE staining was used for histopathological evaluation.

[Role of orphan G protein-coupled receptor 55 in diabetic gastroparesis in mice].

The aim of the present study was to explore the role of orphan G protein-coupled receptor 55 (GPR55) in diabetic gastroparesis (DG). Streptozotocin (STZ) was used to mimic the DG model, and the body weight and blood glucose concentration were tested 4 weeks after STZ injection (i.p.

Role of endogenous cannabinoid system in the gut.

The plant Cannabis has been used in clinic for centuries, and has been known to be beneficial in a variety of gastrointestinal diseases, such as emesis, diarrhea, inflammatory bowel disease and intestinal pain. In this text, we'll review the components of the endogenous cannabinoid system as well as its role in the regulation of gastrointestinal activities, thus providing relative information for further study. Moreover, modulation of the endogenous cannabinoid system in gastrointestinal tract may provide a useful therapeutic target for gastrointestinal disorders.

Resource elasticity of offspring survival and the optimal evolution of sex ratios.

The fitness of any organisms includes the survival and reproductive rate of adults and the survival of their offspring. Environmental selection pressures might not affect these two aspects of an organism equally. Assuming that an organism first allocates its limited resources to maintain its survival under environmental selection pressure, our model, based on the evolutionarily stable strategy theory, surprisingly shows that the sex ratio is greatly affected by the environmental pressure intensity and by the reproductive resource elasticity of offspring survival.

[Evolutionary stability analysis of asymmetric hawk-dove game considering the impact of common resource].

Explaining the evolution of cooperation remains one of the important problems in both biology and social science. Classical theories mainly based on an assumption that cooperative players are symmetrically interacted. However, almost all the well-studied systems showed that cooperative players are in fact asymmetrically interacted and that asymmetric interaction might greatly affect cooperation behavior of the involved players.

Asymmetric interaction will facilitate the evolution of cooperation.

Explaining the evolution of cooperation remains one of the greatest problems for both biology and social science. The classical theories of cooperation suggest that cooperation equilibrium or evolutionary stable strategy between partners can be maintained through genetic similarity or reciprocity relatedness. These classical theories are based on an assumption that partners interact symmetrically with equal payoffs in a game of cooperation interaction.

Aerosol background at two remote CAWNET sites in western China.

The frequency distributions and some statistical features of background aerosol concentrations were investigated at two remote China Atmosphere Watch Network (CAWNET) stations. The estimated elemental carbon (EC) background at Akdala (AKD) in the mid-latitudes of northwestern China (approximately 0.15 microg m(-3)) was only half of that at Zhuzhang (ZUZ) in low-latitude southwestern China (approximately 0.

Chemical characteristics of aerosol particles (PM2.5) at a site of Horqin Sand-land in northeast China.

The objective of this study was to characterize the mass concentration and chemical composition of aerosol particles (PM2.5) collected at Tongliao (Inner Mongolia Autonomous Region, China), a site in Horqin Sand-land in northeast China. During spring 2005, the mass concentration for PM2.

[Clay ratio as a tracer to assess the origin of soil-derived dust].

The objectives of this research are to characterise the mineralogy of soil-derived dust in Northern China and to set up the mineralogical signature to trace their origin. Mineral composition of aerosol particles is investigated at five sites (Aksu, Dunhuang, Yulin, Tongliao and Changwu) during the intensive field campaign period of ACE-Asia. The results show that the Kaolinite (K) to Chlorite (C) ratio is sensitive to the regional origin of Asian dust.
