ObjectiveTo explore the correlation between open field test(OFT) and light-dark box (LDB),as two animal models of state anxiety in Kunming mice.MethodsThe behavior of adult,male,Kunming mice in OFT and LDB was recorded by sequence,for five minutes,with a one-week inter-trial interval.The following parameters were evaluated:percentage of time exploring in the OFT central area( OFT-Ctime％ ) ; percentage of squares crossing in the OFT central area( OFT-Ccross％ ) ; total number of squares crossing in OFT(OFT-Cross) ;total number of rears in the OFT(OFT-Rear) ; number of fecal boli in OFT(OFT-FB) ; percentage of time exploring in the LDB light area( LDB-Ltime％ ) ; percentage of squares crossing in the LDB light area( LDB-Lcross％ ) ;and percentage of rears in the LDB light area( LDB-Lrear％ ) ; transitions between two areas in LDB( LDB-Transition) ; total number of squares crossing in LDB(LDB-Croas) ; total number of rears in LDB(LDB-Rear) ; number of fecal boli in LDB (LDB-FB).Subsequently,factor analysis,cluster analysis and correlation analysis were calculated for these parameters.ResultsFactor analysis and cluster analysis of variances from either OFT or LDB revealed a three behavioral dimensions:anxiety factor ( loaded by OFT-Ctime％,OFT-Ccross％ or LDB-Ltime％,LDB-Lcross％,LDB-Lrear％ ),activity factor ( loaded by OFT-Cross,OFT-Rear or LDB-Transition,LDB-Cross,LDB-Rear) and emotionality factor(loaded by OFT-FB or LDB-FB).While all the variances from both OFT and LDB in combination were analyzed,it could be seen as five components:' LDB-anxiety factor ( loaded by LDBLtime％,LDB-Lcross％ and LDB-Lrear％ ),' OFT-anxiety factor ( loaded by OFT-Ctime％ and OFT-Ccross％ ),'LDB-activity factor (loaded by LDB-Transition,LDB-Cross and LDB-Rear),'OFT-LDB-emotionality factor( loaded by OFT-FB and LDB-FB) and 'OFT-activity factor (loaded by OFT-Cross and OFT-Rear).Good correlation were found between OFT/LDB factors alone and in combination,such as OFT-emotionality factor and LDB-emotionality factor(Pearson =0.383,P＜0.05),LDB-anxiety factor and 'LDB-anxiety factor( Pearson =0.989,P＜0.01 ),OFT-anxiety factor and 'OFT-anxiety factor( Pearson =0.934,P ＜ 0.01 ),LDB-activity factor and 'LDB-activity factor ( Pearson =0.956,P ＜ 0.01 ),OFT/LDB-emotionality factor and ' OFT-LDB-emotionality factor ( Pearson =0.835,P＜0.01 ;Pearson =0.696,P＜0.01 ),OFT-activity factor and 'OFF-activity factor( Pearson =0.926,P＜0.01 ).ConclusionEither OFT or LDB comprised three behavioral dimensions:anxiety factor,activity factor and emotionality factor; however,it was difficult to establish face validity as a point-to-point concordance between OFT and LDB.Attention should be paid to heterogeneity of animal models when OFT and LDB were in combination as a behavionomics to evaluate anxiolytics in Kunming mice.

The concept is cell of the theory. Starting from the concept, is the first and important step in building the modern basic theory of traditional Chinese medicine. Based on the early thought of Changes from phenomenon description to entity elucidation, we firstly introduce conceptual change in this paper and point out its basic meaning and role. To accurately apply the new concept, we have analyzed and demonstrated the concept and its expression object, the concept words' expression forms, as well as the concept explanatory power in details, and pointed out the problems because of ignoring these recognition in researching the concept of chinese medicine and its solutions. We have summarized the laws of the international scientific community realizing the conceptual change focus on the object, explore the unknown, propose new knowledge. and proposed the definition of conceptual change of the basic theory of traditional Chinese medicine. According to preliminary findings we have generalized the goal and standard to achieve the conceptual change of the basic theory of traditional Chinese medicine and gave examples of proof. As such we have draw an conclusion: the concepts of the basic theory of traditional Chinese medicine form the scientific concepts of the modern basic theory of traditional Chinese medicine through conceptual change, and thus guiding the theory, teaching and thinking reform of the Chinese medicine.

AIM: To study the effect of Baixiangdan Capsule (Radix paeoniae alba and Rhizoma cyperi) on expression and behavior and sex hormone of rhesus monkey with premenstrual syndrome (PMS) and liver-qi invasion. METHODS: Twenty-four young rhesus monkeys in high rank and in the ovalatory menstrual cycle were isolated and squeezed 7 h a day for 5 d by specifically designed isolating-cage. At the same time Baixiangdan Capsule orally administed was compared with the control group of Jingqianping Granule. The expression and behavior changes of rhesus monkeys were observed and evaluated by The Measure Table of Emotion Evaluation of Female Experiment Macaque. And the levels of prolactin (PRL),estradiol (E2) and progesterone (P) in serum were investigated by radioimmunoassay. RESULTS: The scores of anxiety factors of the model monkeys were higher than the normal and the serum E2,and P levels decreased and PRL level increased significantly in the control group. As compared with the model group,Baixiangdan Capsule reduced the enhancing anxiety factor scores and also could increase the lower E2 and P levels in serum obviously and decrease PRL level. CONCLUSION: The above findings suggest that Baixiangdan Capsule has good regulative effects and makes it to the normal state on the abnormal expression and behavior and serum sex hormones of rhesus monkey with PMS and liver-qi invasion.

Editor's Notes: The basic theory of traditional Chinese medicine is the theoretical foundation of Chinese medicine , modernization of Chinese medicine needs of the modern theory of Chinese medicine urgently . However , it is always the important issues about how modern Chinese medicine theory should be created , and what kind of theory should have been established concerned and explored by domestic and foreign counterparts in tradi-tional Chinese medicine . To lead the development of modern Chinese medicine theory , Modern Basic Theory of Traditional Chinese Medicine series of symposiums are set up specially in the current Review column, and discussed thoroughly and systematically using three consecutive pats respectively. Among them, part I contains 3 articles about new concepts, new theories, new disciplines; part II contains 5 articles about new ideas, new norms, how to clear concept, how to verify hypotheses, why to evaluate theory; part III contains 12 articles about concept of wholism updating, treatment based on syndrome differentiation development, viscera-state doc-trine innovation, pathogeny, etiology, pathogenesis, prevention, principle of treatment, knowledge structure, cogni-tion structure , monographic study , 5-year outlook . Published article on this issue is the first one belong to new concept of part I. In this paper, we want to describe the denotation and connotation of the new concept of the modern basic theory of traditional Chinese medicine from three aspects of a concept: a label , a theoretical definition , and an operational definition learning from the international academic understanding of scientific concepts, demonstrate the necessity of theoretical premise to the research and establishment of the modern basic theory of traditional Chinese medicine and the need to build on , illustrate the inevitable trend toward modern science . The whole article contains profound meaning and a certain breakthrough and innovation. We are expected to cause concerns and discusses of experts and scholars through this article .
