Objective To find out a reasonable method to weight the quantification indices in TCM syndrome diagnosis through establishing the weight coefficients in diagnosing the kidney deficiency syndrome of senile hypertension patients.Methods The subjective and objective weighting method was adopted to determine the subjective and objective weight coefficients for the Macroscopic Diagnosis Scale of the Kidney Deficiency Syndrome of Senile Hypertension Patients.First

the Delphi method was used to determine the subjective weight coefficient of various items of the scale

then an exploring factorial analysis was done for 300 sample patients to determine the objective weight coefficient.The weight of a certain index obtained from the two were multiplied

and finally

they were processed for normalization.Results The weight values of the items of the scale were dizziness 7

lumbar soreness 8

knee weakness 8

forgetfulness 4

hearing decline 4

hair loss 3

teeth loosening 4

micturition frequency 7

urine dribbling 5

listlessness 8

tiredness 9

shortness of breath 7

somnolence 2

symptoms getting worse when tired 7

pale tongue 3

deep pulse 5

thready pulse 5

and weak pulse 5 respectively.Conclusion The weight values of the target combination of each index in the diagnostic standard of the kidney deficiency syndrome of senile hypertension patients were established

indicating that the combined weighting method in the quantification diagnosis of TCM syndromes is feasible and scientific.
