Effects of different soil and water conservation measures on plant diversity and productivity in Loess Plateau.

Many soil and water conservation measures (SWCM) have been implemented in the Loess Plateau of China, and they have an impact on ecosystems all levels and involve complicated mechanisms. Previously, studies typically focused on a single factor's effect on diversity or productivity. With this background, the current investigation embarked on an extensive study, with vegetation survey conducted in the no measure plots (NM), vegetation measure plots (VM) and engineering measure plots (EM) in the Loess Plateau of China.

The Correlation between Atrial Fibrillation and Prognosis and Hemorrhagic Transformation.

Objective: Atrial fibrillation (AF) is the recognized risk factor for hemorrhagic transformation (HT) in thrombolysis patients with acute ischemic stroke (AIS). But the impact of AF on prognosis is still controversial. In our study, we aimed to assess the relationship between AF and HT and prognosis.

Analytical and simulation studies of driven diffusive system with asymmetric heterogeneous interactions.

Totally asymmetric simple exclusion process (namely, TASEP) is one of the most vital driven diffusive systems, which depicts stochastic dynamics of self-driven particles unidirectional updating along one-dimensional discrete lattices controlled by hard-core exclusions. Different with pre-existing results, driven diffusive system composed by multiple TASEPs with asymmetric heterogeneous interactions under two-dimensional periodic boundaries is investigated. By using detailed balance principle, particle configurations are extensively studied to obtain universal laws of characteristic order parameters of such stochastic dynamic system.

[Advances in studies on bear bile powder].

In this paper, a detailed analysis was made on relevant literatures about bear bile powder in terms of chemical component, pharmacological effect and clinical efficacy, indicating bear bile powder's significant pharmacological effects and clinical application in treating various diseases. Due to the complex composition, bear bile powder is relatively toxic. Therefore, efforts shall be made to study bear bile powder's pharmacological effects, clinical application, chemical composition and toxic side-effects, with the aim to provide a scientific basis for widespread reasonable clinical application of bear bile powder.

[Illumination of pharmacoeconomics on Chinese herbal medicine inject].

This text emphasizes the present condition of the production and usage to Chinese herbal medicine inject, from the research angle of view of the pharmacoeconomics. Inquiry into the Chinese herbal medicine injects of the funds throw and throw in a funds and resources, the output of clinical health result and output a circumstance with social welfare, explicit the Chinese herbal medicine injected to take up a great deal of medicine health resources, but output not optimistic. Put forward the important meaning of pharmacoeconomics evaluation to Chinese herbal medicine inject that appears on market behind and carry on the main contents of the pharmacoeconomics evaluation thus.

[Safety issues of traditional Chinese medical preparations containing arsenic substances: review starting from Niuhuang Jiedu Pian (Wan)].

By comprehensively reviewing the origin and history of Niuhuang Jiedu Wan and its "derivatives", we studied the clinical records of realgar, investigated its clinical usage, dosage, efficacy, and toxicity in the literatures. We pinpointed the factors that might be associated with safety problems of Niuhuang Jiedu Pian (Wan) and other traditional Chinese medicine (TCM) preparations containing arsenic substances. In this article we also put forward suggestions for strengthening the surveillance and administration of similar TCM preparations.
