Background: The biophysical properties of the meridian system, an important concept of traditional Chinese medicine, include low impedance, resounding voice, and high acoustic conductance, all of which are helpful for elucidating the essence of meridians. Objectives: To visualize the human pericardium meridian (PC) based on the resounding voice property of meridians. Methods: Visualization of the PC was performed by injection of fluorescein sodium at the PC6 acupoint (Neiguan) on the PC. Before injection, percussion active points (PAPs) were identified by the virtue of their resounding voice properties. After injection, the trajectories of fluorescein migration throughout the body surface were recorded and analyzed. The distribution of fluorescein in the tissue was further studied using cross-sections of hind limbs of mini-pigs, in which fluorescein was injected into low impedance points. Results: The identified PAP lines were colocalized with PC. Following intradermal fluorescein injection, 1-3 fluorescent lines, which were unrelated to the arm veins, were observed in 7 of 10 participants; 85.4% of fluorescent signals were coincident with PAPs and their intensity had a negative correlation with the body mass index (r = –0.56, p = 0.045). Cross-sections showed a Y-shaped fluorescence pattern where the two migration lines on the surface were the two vertices of the “Y.” Conclusion: The trajectories of fluorescein in the body are suggestive of the anatomical structure of meridians. The PC is related to the deep horizontal interstitial channels that connect to the body surface through vertical interstitial spaces. These biophysical properties and techniques for meridian visualization are valuable for revealing the anatomical structure of meridians.

Selenium is a harmful trace element emitted during the combustion process of coal-fired power plants. Most of the selenium is enriched in the downstream wet flue gas desulfurization system (WFGD). Thisstudy found that S2O28 is the most important factor affecting the oxidation of selenite. In the processof simulating slurry oxidation of selenite to selenate, the presence of S2O28 can increase the oxidationrate of selenate from about 50% to about 80%. At the same time, this study also considered the influenceof selenium concentration, initial pH, SO2 concentration and temperature etc. on the transformation ofselenium species. It was believed that the application of ORP to the indication of selenite oxidation statusneeds further demonstration. Energy Dispersive X-Ray Spectroscopy (EDX) and X-ray photoelectron spectroscopy(XPS) were used to confirm the migration of selenium in the desulfurization slurry to gypsum. Inaddition, DFT calculation was performed to obtain theoretical parameters for the adsorption of seleniteand selenate by gypsum. The results of this study are helpful to understand the transformation andmigration of selenium in the desulfurization system, which provide theoretical support for the realizationof selenium in-situ control.
