The combination of acupuncture and Tuina has a preferable curative effect in the treatment of this disease. However, the studies on treatment with acupuncture and tissue separating manipulation are quite limited. The author has treated 100 cases of scapulohumeral periarthritis with acupuncture and tissue separating manipulation during recent 10 years. Here comes the report.展开更多
Two new supramolecular complexes [MnL（H2O） 4]（1） and [ZnL（H2O） 5]·0.25H2O（2） （H2L = 5-carboxy-1-carboxymethyl-2-oxidopyridinium） have been synthesized and structurally characterized by elemental analysi...Two new supramolecular complexes [MnL（H2O） 4]（1） and [ZnL（H2O） 5]·0.25H2O（2） （H2L = 5-carboxy-1-carboxymethyl-2-oxidopyridinium） have been synthesized and structurally characterized by elemental analysis,IR and X-ray single-crystal structure determination. Complex 1 crystallizes in the monoclinic system,space group P21/n with a = 5.1537（2） ,b = 21.2008（9） ,c = 10.9727（4）A,β = 99.182（2） °,V = 1183.54（8）A^3,C8H13MnNO9,Mr = 322.13,Dc = 1.808,Z = 4,F（000） = 660,μ = 1.160,R = 0.0372 and wR = 0.0750 for 2217 observed reflections（I 〉 2σ（I）） . Complex 2 crystallizes in the triclinic system,space group P1^- with a = 7.730（2） ,b = 8.030（2） ,c = 11.400（2） A^3,α = 104.27（3） ,β = 92.93（3） ,γ = 102.67（3） °,V = 664.9（2） 3,C8H15.5ZnNO10.25,Mr = 355.08,Dc = 1.774,Z = 2,F（000） = 365,μ = 1.899,R = 0.0243 and wR = 0.0695 for 2759 observed reflections（I 〉 2σ（I）） . Their thermal properties have been studied.展开更多
