摘要:OBJECTIVE: To analyze the distribution and characteristics of TCM constitution in patients with primary biliary cholangitis(PBC). METHODS: 138 PBC patients who met the inclusion criteria were divided into 3 groups according to the stage of disease development: group A(group of basic normal), group B(group of symptom stage) and group C(group of decompensation stage). Each group collected 46 cases, and every patient was reexamined, which included blood routine examination, liver function test, image ultrasound examination, autoantibody examination and immunoglobulin test. Then, the patients’ clinical symptoms were observed and recorded, and their constitution of traditional Chinese medicine were classified. RESULTS:(1) For 138 patients with PBC, their TCM constitution was characterized by biased constitution, among which constitution of Qi stagnation(19.57%) was the majority, which was followed by constitution of Qi asthenia(15.94%), constitution of Yin asthenia(15.94%) and constitution of damp-heat(14.49%). There was no significant correlation between the type of constitution and the age of onset(P>0.05).(2) The constitution types of group A and B were mainly constitution of Qi stagnation, constitution of Qi asthenia and constitution of damp-heat, while group C was mainly composed of constitution of blood stasis, constitution of Yin asthenia and constitution of Yang asthenia.(3) The highest positive rate of autoantibodies in patients with PBC was constitution of Qi stagnation, which was followed by constitution of damp-heat, constitution of Yin asthenia and constitution of Qi asthenia. The most abnormal liver function and immunoglobulin were constitution of Qi stagnation, which was followed by constitution of Qi asthenia, constitution of Yin asthenia, constitution of damp-heat.CONCLUSION: Constitution of Qi stagnation, constitution of Qi asthenia, constitution of damp-heat and constitution of Yin asthenia were the susceptible constitutions of PBC patients.
