The combination of Danggui and Honghua (GH) is a popular herb pair commonly used in clinic for the treatment of blood stasis syndrome in China. To evaluate the activating blood circulation and dissipating blood stasis effects of the combination of different proportions of Danggui and Honghua on acute blood stasis rats, and optimize the proportion of GH to have the best activating blood circulation and dissipating blood stasis effect. Acute blood stasis rat model was induced by subcutaneous injection of adrenaline and ice water bath. The blood stasis rats were administrated intragastrically with GH (1 : 0, 4 : 1, 2 : 1, 3 : 2, 1 : 1, 2 : 3, 1: 2, 1 : 4 and 0 : 1) extracts. The whole blood viscosity (WBV), plasma viscosity (PV), and high shear whole blood relative index (HSWBRI), low shear whole blood relative index (LSWBRI), and erythrocyte aggregation index (EAI) were tested to observe the effects of GH on hemorheology of blood stasis rats. And the maximum aggregation induced by adenosine diphosphate (ADP) was tested to observe the effect of GH on platelet aggregation index of blood stasis rats. In addition, the prothrombin time (PT), thrombin time (TT), activated partial thromboplastin time (APTT) and plasma fibrinogen (FIB) were tested to observe the effects of GH on blood coagulation function of blood stasis rats. Then principal component analysis and multi-attribute comprehensive index methods were both used to comprehensively evaluate the total activating blood circulation and dissipating blood stasis effects of GH. The results showed that the hemorheological indexes and coagulation parameters of model group both had significant differences with normal group. Compared with model group, GH (1 : 0, 4 : 1, 2: 1, 3 : 2, 1 : 1, 2 : 3, 1 : 2, 1 : 4 and 0 : 1) could improve all the blood hemorheology indexes and regulate part indexes of blood coagulation function and platelet aggregation in acute blood stasis rats. Based on principal component analysis and multi-attribute comprehensive index methods, GH 1 : 1 and GH 3 : 2 both had the best effect of blood circulation and dissipating blood stasis, and the effect of GH 1 : 1 was slightly better than GH 3 : 2. These results suggest that GH could obviously ameliorate the abnormality of hemorheology and blood coagulation function in acute blood stasis rats. The optimized proportion of GH was consistent with regulations of medicine usage that GH 1 : 1 had the highest frequency used in traditional Chinese formulae. It could provide scientific basis for more effective application of the compatibility between Danggui and Honghua in modern clinic medicine.

Objective To investigate the expression of the interleukin-1 receptor(IL-1R)Ⅰ,IL-1RⅡand IL-1R accessory protein(IL-1RAcP)in osteoarthritis and analyse their biological significance.Methods Immunohistochemistry and reverse transcription-polymerase chain raction(RT-PCR)were adopted to detect the expression of IL-1RⅠ,IL-1RⅡand IL-1RAcP on the synovium of 107 OA patients.Results Immunohis- tochemistry showed strong positive expression of IL-1RⅠand IL-1RAcP,and positive expression of IL-1RⅡ. The expression was distributed in lining cells,monocyts and vascular endothelial cells of the sublining area, but all of them were negative or weak positive in normal synoviums.RT-PCR showed the expression of IL-1RⅠ,IL-1RⅡand IL-1RAcP in OA synoviums was significantly enhanced than normal synoviums (P＜0.05),and the expression of IL-1RⅠwas significantly enhanced than IL-1RⅡ(P＜0.05),but no sig- nificant difference with IL-1RAcP(P＞0.05).In stageⅡandⅢOA synoviums,the expression of IL-1RⅠand IL-1 RAcP had no significant difference with normal synoviums(P＞0.05).The expression of IL-1RⅡin stageⅢOA synoviums was significantly enhanced than normal(P＜0.05).Conclusion IL-1RⅠ,IL-1RⅡand IL-1RAcP play significant roles in the pathogenesis of OA,especially IL-1RⅠand IL-1RAcP.But their increase is only observed in the early stage of OA.These suggest that they may have no association with the development of OA and have no direct association with the severity of OA.OA can be cured by interrupting the signal transduction path in which IL-1 has played biological roles.

The effects of the feed attractants on Whitmania pigra were studied. The average weight of Wh. pigra were 5.0 g. Arginine was selected as feed attractants, xanthan gum was selected as feed substrate. The times of Wh. pigra going into the inducing room were recorded. The water temperature was 22-25 degrees C during the whole experiment. Arginine that had better inducing effect was chosen to carry on in the gradient experiment. The results showed that the best inducing effect was found when the added amount of arginine was 0.3%, which was close to the arginine content of the natural body fluid of Wh. Pigra and Bellamya purificata, 2.97 mg x g(-1).
