Objective To compare the difference of skin microcirculation blood perfusion volume（MBPV） at the lowest tenderness threshold of T

spinous processes in the dorsal segment of Governor Vessel of patients with chronic gastritis and healthy subjects. Methods A total of 30 patients with chronic gastritis were in the gastritis group

and 20 healthy people were in the healthy group. Through the method of electronic pressure pain measurement

the tenderness values were measured under the spinous processes of the T

and a three-channel laser Doppler flowmeter Record the MBPV of the test and control points were used. The pain measurement values and MBPV of the test points and control points of the 2 groups were compared

and the correlation analysis between the pain measurement values of both groups and the corresponding MBPV was performed. Results Compared with T
