Objective To determine the effects of EGCG on lipopolysaccharide ( LPS)-induced neuroinflamma-tion and investigate the role of neuroprotection mediated by EGCG .Methods Primary cultures of rat gliacyte were used as an in vitro model to examine the effects of EGCG on LPS-induced neuronal damage .The intracellu-lar Glu andγ-GABA were quantified via HPLC .Then the protein level of TNF-α,IL-1βand IL-8 was determined by ELISA and Western blot assay .Results Compared with the control group , LPS apparently induced the pro-duction of intracellular ROS ( P<0.05 ) and released the TNF-α, IL-1βand IL-8 in the primary cultures super-natant (P<0.05).Compared with the LPS group,EGCG significantly attenuated the release of TNF-α, IL-1βand IL-8 ( P<0.05 ) and the level of iNOS protein ( P<0.05 ) .LPS apparently induced the production of intra-cellular ROS( P<0.05 ) and released the TNF-α, IL-1βand IL-8 in the primary cultures supernatant ( P <0.05 ) .EGCG significantly attenuated the release of TNF-α, IL-1βand IL-8 ( P<0.05 ) and the level of iNOS protein(P<0.05), and rugulated the concentration of Glu/γ-GABA(P<0.05).Conclusions EGCG is effective in protecting hosts against LPS-induced neuroinflammation through anti-inflammatory effects and regulating extracel-lular Amino acid levels .

OBJECTIVE:
To observe the expression of discs large homolog 4 (DLG4) protein in hippocampus, amygdala and frontal cortex of rats and evaluate postsynaptic density in heroin dependence.
METHODS:
The rat heroin dependent model was established by increasing intraperitoneal injection of heroin. DLG4 proteins in hippocampus, amygdala and frontal cortex of heroin dependent 9, 18, 36 days rats were detected with immunohistochemical staining and compared with that in the control group.
RESULTS:
DLG4 proteins in hippocampus, amygdala and frontal cortex were gradually reduced with extension of heroin dependent time.
CONCLUSION
Heroin dependence can affect postsynaptic density of hippocampus, amygdala and frontal cortex. The changes become more apparent with extension of heroin dependence time.

Objective To explore the relationship between social participation and needs for rehabilitation of the disabled in Guangdong Province and to make a proposal for developing the rehabilitation strategies. Meth-ods The data of the Second National Sample Survey of Disabled Persons in Guangdong Province was used in this study. Ranked data analysis was made with the sub-items of the social participation assessment and the main needs of the disabled individuals. Results Significantly statistical differences were revealed with regard to the constitu-ent ratio of needs for rehabilitation services among people with different degrees of difficulties in social participation caused by hearing and visual impairments as well as physical and mental disabilities. No significant difference was found in terms of the constituent ratio of rehabilitation needs among those with difficulties in speech and those with psychiatric diseases. The major rehabilitation needs focused on medical service, assistive apparatus support and functional trainings. Conclusions The rehabilitation needs were different among different categories of disabled persons. Rehabilitation services should be provided accordingly.

The study on the pharmacokinetics of traditional Chinese medicines (TCMs) is a linking science during the modernization of TCMs, and plays an important role in the studies on the complex material base of TCMs, the in vivo process of ingredient/ component and the pharmacokinetics-pharmacodynamics correlation. However, because of the multi-ingredient/component system of TCMs, how to scientifically reveal the pharmacokinetics that is consistent with TCMs' characteristics has long been a hotspot and difficulty for the exploration. The optimal composition structure of the material basis of TCMs shows the best efficacy, while the difference between the multi-ingredient/component composition structures in the efficacy is closely related to their absorption, transport, metabolism and excretion in vivo. In this article, the authors systematically review the study methods for pharmacokinetics of TCMs and their compounds, and explore the pharmacokinetics of TCMs based on the "component structure theory". As a result, the method for integrating TCM component structure and the TCM pharmacokinetics was proposed to be adopted to intensively study the effect of the component structure on the in vivo TCM multi-ingredient/component pharmacokinetic characteristics, in order to promote the TCM modernization and innovation in China.

The purpose of the secondary exploitation of Chinese medicine is to improve the quality of Chinese medicine products, enhance core competitiveness, for better use in clinical practice, and more effectively solve the patient suffering. Herbs, extraction, separation, refreshing, preparation and quality control are all involved in the industry promotion of Chinese medicine secondary exploitation of industrial production. The Chinese medicine quality improvement and industry promotion could be realized with the whole process of process optimization, quality control, overall processes improvement. Based on the "component structure theory", "multi-dimensional structure & process dynamic quality control system" and systematic and holistic character of Chinese medicine, impacts of whole process were discussed. Technology systems of Chinese medicine industry promotion was built to provide theoretical basis for improving the quality and efficacy of the secondary development of traditional Chinese medicine products.

Fatigue is an exhaustion state caused by prolonged physical work and mental work, which can reduce working efficiency and even cause industrial accidents. Fatigue is a complex concept involving both physiological and psychological factors. Fatigue can cause a decline of concentration and work performance and induce chronic diseases. Prolonged fatigue may endanger life safety. In most of the scenarios, physical and mental workloads co-lead operator into fatigue state. Thus, it is very important to study the interaction influence and its neural mechanisms between physical and mental fatigues. This paper introduces recent progresses on the interaction effects and discusses some research challenges and future development directions. It is believed that mutual influence between physical fatigue and mental fatigue may occur in the central nervous system. Revealing the basal ganglia function and dopamine release may be important to explore the neural mechanisms between physical fatigue and mental fatigue. Future effort is to optimize fatigue models, to evaluate parameters and to explore the neural mechanisms so as to provide scientific basis and theoretical guidance for complex task designs and fatigue monitoring.

Chinese medicine prescriptions are the wisdom outcomes of traditional Chinese medicine (TCM) clinical treatment determinations which based on differentiation of symptoms and signs. Chinese medicine prescriptions are also the basis of secondary exploitation of TCM. The study on prescription helps to understand the material basis of its efficacy, pharmacological mechanism, which is an important guarantee for the modernization of traditional Chinese medicine. Currently, there is not yet dissertation n the method and technology system of basic research on the prescription of Chinese medicine. This paper focuses on how to build an effective system of prescription research technology. Based on "component structure" theory, a technology system contained four-step method that "prescription analysis, the material basis screening, the material basis of analysis and optimization and verify" was proposed. The technology system analyzes the material basis of the three levels such as Chinese medicine pieces, constituents and the compounds which could respect the overall efficacy of Chinese medicine. Ideas of prescription optimization, remodeling are introduced into the system. The technology system is the combination of the existing research and associates with new techniques and methods, which used for explore the research thought suitable for material basis research and prescription remodeling. The system provides a reference for the secondary development of traditional Chinese medicine, and industrial upgrading.
