30 patients without malignant tumor

and 30 healthy examinees were included. Combining modern technology with the TCM theory of pulse diagnosis

according to demand of three regions and nine divisions pulse taking sites

dynamic pulse manifestation information of six positions of two wrists of each subject was collected using "Three-probe TCM Pulse Pattern Diagnosis Acquisition and Analysis System"in our laboratory. Then the comprehensive analysis was carried on by the integration of comparative analysis and TCM syndrome differentiation.Results The specific changes were found in malignant tumor patients

especially rough pulse with its variability and bimodal M wave. In addition

the detection rate of abnormal pulse was 80%

statistical difference compared with patients without malignant tumor and healthy persons. Conclusion It is suggested that the characteristic changes of pulse manifestation information of patients with malignant tumor

correlation between malignant tumor and pathological changes of disorders of zang-fu organs

qi
