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.
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.
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.
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.
