Analysis on combination regularities of Houxi (SI3) in ancient times of China based on latent structure model
Objective To explore the feasibility and application value of combination regularities of acupoint Houxi(SI3) in Chinese ancient times based on latent structure model. Methods Relevant articles about SI3 for treating various diseases with acupuncture
moxibustion
acupoint application
etc. were mainly searched from book Chinese Medical Classics(5 th edition)
followed by establishment of a Database of Houxi Acupoint Recipes. The Lantern 5.0 software was used to construct and analyze the latent structure model of high-frequently-used acupoints. Results A total of 46 high frequently-used acupoints contained in 240 articles of 26 medical books were collected. The top 7 acupoints are Shenmai(BL62)
Hegu(LI4)
Qiangu(SI2)
Fengchi(GB20)
Jianshi(PC5)
Wangu(SI4) and Quchi(LI11) in sequence. After modeling the 46 high-frequently used adjunct acupoints
12 latent variables(Y0-Y11) and 24 latent classes were obtained by setting the cumulative coverage threshold ratio to be 95%. According to the Bayesian information criterion(BIC) measure
the model score was-2 170.68 points. Seven comprehensive clustering models were summarized up according to the latent structure. Compared with the yin meridians
the yang meridians played a more significant role. The multiple combinations of SI3 with specific acupoints provided a reference for clinical practice. The supplementary acupoints mainly distribute in the upper and lower limbs
head
face
neck
etc. and the SI3 acupoint recipes function mainly in dredging and activating meridians and collaterals
clearing away pathologic heat and wind
improving eyesight
and relieving swelling and pain. Conclusion The latent structure model is applicable in analysis of the regularities of SI3 acupoint combination for treating some diseases. Comprehensive clustering is employed to determine the primary acupoint SI3 and adjunct acupoint matching
revealing the common regularity and logical progressive relationship between the primary and secondary points
