[On establishing comparative reference system for syndrome classification study from the thinking characteristics of syndrome differentiation dependent therapy].

To create a comparative referential system for syndrome classification study by viewing from the thinking characteristics of TCM on syndrome differentiation dependent therapy (SDDT), through analyzing the thinking process of SDDT, and the basic features of disease, syndrome and prescription, combining the basic principles of modern evidence-based medicine and feasibility of establishing integrative disease-syndrome animal model. The practice of creating a comparative referential system based on clinical efficacy of prescription was discussed around syndrome pathogenesis and its relationship with disease and prescription, which was one of the important scientific problems in TCM syndrome study. The authors hold that, it may be one of the available approaches for the present study on integration of disease with syndrome by way of insisting on the thinking pathway of stressing the characteristics of TCM and intermerging with modern scientific design; on taking the efficacy of prescription as the comparative reference system to accumulate and improve unceasingly according to the TCM method of syndrome diagnosis inferred from effect of prescription with reverse thought (i.e., to differentiate syndrome from the effect of prescription), and thus build up the syndrome diagnostic standard on the solid clinical and scientific base.

[The effect of four kinds of traditional Chinese herbal compound on the experimental acute stress behaviors and the hypothalamus-pituitary-adrenal gland axis].

OBJECTIVE: To study the effects of four kinds of traditional Chinese herbal compound, Sini powder, Banxiahoupu soup, Ganmaidazao soup and Guizhigancaolonggumuli soup, on the experimental acute stress behaviors and the hypothalamus-pituitary-adrenal gland axis. METHOD: Rats were divide into 7 groups: normal group, model 1 and 2 groups, Sini powder group, Banxiahoupu soup group, Ganmaidazao soup group, and Guizhigancaolonggumuli soup group. The behaviors of the rats and their CRH of the hypothalamus, ACTH of plasma and CORT of serum (by the means of radio-immunity) were detected. RESULT: Sini powder could reduce the crossing times of open-field test( P < 0.01) and the contents of CRH and CORT (P < 0.01, P < 0.05); Banxiahoupu soup could extent the still time of tail-hanging test ( P < 0.05) and the content of CRH (P < 0.05); Ganmaidazao soup could prolong the still time (P < 0.05) and reduce the struggle times (P < 0.01) of tail-hanging test and reduce the contents of CRH, ACTH and CORT (P < 0.01, P < 0.05); Guizhigancaolonggumuli soup could reduce the crossing times of open-field test (P < 0.01) , extent the still time (P < 0.05) and reduce the struggle times ( P < 0.01) of tail-hanging test of tail-hanging test, also reduce the contents of CRH, ACTH and CORT (P < 0.01, P < 0.05). CONCLUSION: The four kinds of traditional Chinese herbal compound can increase the ability of anti stress by affect the different taches of the hypothalamus-pituitary-adrenal gland axle and change the stress behaviors, which are based on their respective functions of regulating Qi, dispersing phlegm, tonifying Qi and warming Yang.

[Protective and therapeutic effects of Shugan Lifei Recipe on rats with asthma under stress and the mechanisms].

OBJECTIVE: To explore the influence of psychological factor on asthma, the protective and therapeutic effects of Shugan Lifei Recipe on rats with asthma under stress and the mechanisms. METHODS: Allergy and stress-induced asthma models were established in rats by giving ovalbumin and restraining stress. Radioimmunoassay, enzyme linked immunosorbent assay, in situ hybridization and immunohistochemical method were used to detect plasma corticosterone, IL-4, IFN-gamma, expression of glucocorticoid receptor (GR) mRNA in hippocampus and adrenocorticotropic hormone corticoliberin (CRH) positive neuron in hypothalamus. Optical and electron microscopes were used to observe the morphological changes of pulmonary hilar and hippocampal tissues. RESULTS: Shugan Lifei Recipe (SGLFR) could reduce plasma corticosterone, decrease CRH positive neurons in paraventricular nucleus of hypothalamus, up-regulate the expression of GR mRNA in hippocampus and reduce the injury of hippocampal neuron. SGLFR had certain inhibitive effect on hyperfunction of hypothalamo-pituitary-adrenal cortex (HPA) axis in rats with asthma under stress and could also relieve the pathological changes of the pulmonary hilar tissue. The level of plasma IFN-gamma was increased while the level of plasma IL-4 was decreased in SGLFR-treated group. CONCLUSION: The mechanism of SGLFR in treating the rats with asthma under stress is probably to regulate the hyperfunction of HPA axis and the disorder of immuo-system.
