Methods A total of 19 healthy subjects were recruited for this study. The PeriCam Perfusion Speckle Imager System was used to investigate skin microcirculation perfusion of the Du Meridain and the first line of Bladder Meridian simultaneously before/during/after moxibustion (5-30min). Coherence analysis between these meridians were conducted by linear statistics. Results The perfusion unit of Du Meridian was higher than Bladder Meridian on the back of the healthy subjects (p&lt;0.05). Meanwhile, there were no significant difference between Bladder Meridians on both side; After moxibusion treatment, the perfusion units of acupoints on both of the Du Meridian and first line of Bladder Meridian has increased significantly compared to the non-meridian points in back. It may indicate the meridians have heat conductivity.Conclusions Microcirculatary perfusion on the merdians has difference compared with other area. It suggests that the meridians on back have a characteristic of heat conducitity.&nbsp;</p><p><br/></p><p>Key words Governor Meridian, moxibustion, laser speckle, microcirculatary perfusion of skin, perfusion unit</p><p><br/></p>
