ABSTRACT
OBJECTIVE@#To compare the distribution characteristics of pressing sensitive acupoints on the body surface between bronchial asthma (BA) patients and healthy subjects, and to analyze the distribution rules of pressing sensitive acupoints in BA patients.@*METHODS@#Seventy BA patients and 70 healthy subjects were selected in this study. The pressing sensitive acupoints were checked with finger pulp and marked on human nerve segment graph. The numbers of pressing sensitive acupoints were counted and the positional relationship between distribution of pressing sensitive acupoints and the position of meridians and nerve segment was observed.@*RESULTS@#(1) The incidence rates of pressing sensitive acupoints in BA patients group and healthy subjects group were 91.4% (64/70) and 15.7% (11/70) respectively, and the BA patients group was higher than the healthy subjects group (<0.01). (2) The top 3 meridians with pressing sensitive acupoints occuring in BA patients were bladder meridian of foot-, lung meridian of hand- and large intestine meridian of hand-, and the most frequent pressing sensitive acupoints were Feishu（BL 13）, Xinshu（BL 15）, Chize（LU 5） and Jueyinshu (BL 14). (3) The pressing sensitive acupoints in BA patients were distributed mainly on C, C and T-T nerve segment.@*CONCLUSION@#Pressing sensitive acupoints have a close correlation with physical condition, and there is a close relation between pressing sensitive acupoints distribution and corresponding meridians and nerve segments in BA patients.
ABSTRACT
OBJECTIVE: To compare the distribution regularity of the pressure-sensitive acupoints in patients with chronic non-atrophic gastritis (CNAG) and healthy subjects, so as to provide suitable acupoint combinations for clinical treatment. METHODS: A total of 120 volunteer subjects including 60 CNAG patients (29 men and 31 women, (40.7±10.3) years at the average age) and 60 healthy subjects (28 men and 32 women, and (40.8±10.2) years at the average age) were enrolled in the present study. The pressure-sensitive acupoints were checked by a fixed operator using his finger pulp along the body trunk and the four limbs and marked on a prepared human dermatome graph. The number of pressing sensitive acupoints were counted, and the relationship between the distribution of the detected sensitive acupoints and the position of meridians and nerve segments was analyzed. RESULTS: The incidence of pressure-sensitive acupoint in CNAG patients and healthy subjects were 86.7% and 15.0%, respectively. In 60 CNAG patients, the most frequently met sensitive acupoints were Xuehai (SP10), Zhongwan (CV13), and Zhongting (CV17) in sequence, mainly covering the Conception Vessel, Spleen Meridian of Foot-Taiyin (SP), and the Stomach Meridian of Foot-Yangming (ST). The sensitive acupoints presented a nerve-segmental distribution within T7-T10 and L3-L5. CONCLUSION: The pressure-sensitive acupoints present a nerve-segmental distribution and have a higher corresponding rate with some meridians related to the stomach, especially under diseased conditions.
ABSTRACT
OBJECTIVE@#To observe the correlation between referred pain distribution and acupoint sensitization in patients with intestinal diseases.@*METHODS@#In clinical research, 443 patients from 8 hospitals were recruited, including the outpatients and inpatients of Crohn's disease (=143), ulcerative colitis (=108), chronic appendicitis (=87) and other intestinal diseases (=105). The site with tenderness on the body surface and the morphological changes of local skin were observed and recorded in the patients. Using a sensory tenderness instrument, the pain threshold at the sensitization point was measured in 60 patients with ulcerative colitis. In animal experiment, SD rats were used and divided into a enteritis group (=8), in which the enteritis model were established, and a control group (=3), in which no any intervention was given. After the injection of Evans blue (EB) at caudal vein, the blue exudation points on the body surface were observed and the distribution rule was analyzed statistically.@*RESULTS@#The referred pain on the body surface in the patients with intestinal diseases was mainly located in the lower abdomen (93.9%, 416/443), the lumbar region (70.9%, 314/443) and the lower legs (33.0%, 146/443). The diameter of tenderness region was 1.5 to 2.5 cm. Compared with the region without sensitization, the pain threshold of the sensitization point in the patients with ulcerative colitis was reduced significantly (<0.001). The referred pain on the body surface in the patients with appendicitis was located in the right lower abdomen (97.7%, 85/87), the waist and back (54.0%, 47/87) and the right lower limbs on the medial side (71.3%, 62/87). The tenderness region was 1 to 2 cm in diameter and was irregular in form. After modeling of enteritis in the rats, the EB exudation points were visible from T to L.@*CONCLUSION@#Intestinal diseases induce referred pain on the body surface where is the same as or adjacent to the location of the spinal segment corresponding to the affected intestinal section. These sensitization regions are related to the locations of acupoints.
