Objective To study the classification and diagnosis of TCM syndromes of rheumatoid arthritis in the active stage by using variable clustering analysis. Methods Clinical data of 237 cases of rheumatoid arthritis in active stage, including symptoms, signs and manifestation of tongue and pulse, were recorded and dealt with cluster analysis. Results TCM syndromes in the patients were classified into four types, including pathogenic factor and depression in collaterals, intermingled phlegm and blood stasis, blokage due to damp-heat, blood stasis and qi deficiency, and main diagnostic points were determined for different syndromes initially. Conclusion The variable clustering analysis combined with expert’s opinion is helpful to study the classification of TCM syndromes and main diagnositic points of rheumatoid arthritis in active stage.

?-adrenoceptor,whose subtypes ?1-and ?2-adrenoceptor are expressed on panreatic cancer cells,is closely related to the occurrence and development of pancreatic cancer.?-adrenoceptor agonists epirenamine,isopropylarterenol and the tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone(NNK) induce pancreatic cancer proliferation.Research on the molecular mechanism is as follows: Activating ?-receptor can stimulate protein kinase A(PKA)/arachidonic acid(AA) pathway in pancreatic cancer cells.NNK also stimulates mutation of Ras and the activation of Src tyrosine kinase and Ras,followed by activation of mitogen activated protein kinase(MAPK) pathway.?-adrenoceptor can make the epidermal growth factor(EGFR) pathway transactivated,and the EGFR and ?-adrenergic signalling pathways might synergize to activate Src and Ras.Increased evidence suggests that patients with pancreatic adenocarcinoma share many risk factors,such as smoking and chronic depression,with cardiovascular disease patients.Drugs to block ?-adrenoceptor in cardiovascular diseases might be used for the prevention and treatment of pancreatic cancer.
