| To observe the pressure pain threshold (PPT)of acupoints and its sensitivity of patients with intestinal cancer and functional bowel disease by electronic von fray.Methods:PPT was detected on 13 acupoint related to intestinal disorders, 1 cun, 2 cun beside the acupioints and the hemosegement points among the patients of intestinal cancer (IC), functional constipation (FC), functional diarrhea (FD) and compared those with those of the normal control group(Con).The control points were on the heterosegement.The results showed that the PPTs of acupoints ST 36, ST 37, ST39, and its adjacency 1 cun, 2 cun beside those acupioints of IC, FC, FD groups are significantly lower compared with the Con group (P<0.05), though with high sensitivity.Meanwhile, the LI11 still markedly sensitized (P<0.05) around 1 cun of the acupoint, but PPT is lower than the control group(P<0.05).For IC group, the PPTs of SP9 and BL25 increased significantly (P<0.05) around 2 cun of the acu-points, but this did not occur in FC or FD groups.The results indicated that acupoints include ST36, ST37, ST39, and LI11 in IC, FC, and FD groups became more sensitive with a wider area.Besides, for IC patients, BL25 and SP9 were also sensitized with a wider area. |
