A three-dimensional coordination polymer {[Cd2（HCAM）2（H2O）4].***2O}n was synthesized by the hydrothermal reaction of H3CAM （H3CAM = 4-hydroxypyridine-2,6-dicerboxylic acid） and Cd（NO3）2·4H2O. The structure was characterized by elemental analysis, thermal grav.metric analysis, infrared spectroscopy and single-crystal X-ray diffraction. It crystallizes in triclinic, space group P1 with a = 9.4389（19）, b = 11.009（2）, c = 11.192（2） A, α = 87.87（3）, β= 74.63（3）, γ = 81.22（3）°, v. 1108.2（4） A3, Z = 2, Dc= 2.164 g/cm3,μ = 2.011 mm^-1, F（000） = 710, R = 0.0419 and wR = 0.1170. X-ray analysis rev.als that the title compound adopts a one-dimensional staircase structure by carboxyl of H3CAM and water molecules, and it is further linked by hydrogen bonds to form a 3-D metal-organic open framework. The thermal grav.metric analysis displays that the framework exists stably below 300 ℃.

In this paper the making of homeostatic models of the bioenergetic informational acupunctural human’s system of the “Pentacube” and the “Hexagon” according to the Wu Xing rules and energy shifts dynamics is considering. The making of the meridional homeostatic model of the bioenergetic informational acupunctural human’s system based on the existing knowledges about the human body meridians is considering. Preference to choice of the homeostatic functional models of the human body organs energies interaction is substantiated. The meridional control submodel of homeostatic system is defined and constructed. The description of control submodel, perspectiv.s of application and dev.lopment are represented.
