Methods: Two hundred and five patients were randomly divided into a warming needle moxibustion group (68 cases), a HESPT group (68 cases) and a point-injection group (69 cases). In the warming needle moxibustion group, the main points of Xuehai (SP 10), Neixiyan (EX-LE4), Waixiyan (EX-LE5), Dubi (ST 35), Zusanli (ST 36) and Yanglingquan (GB 34), and the adjunct points of Yinlingquan (SP 9) and Sanyinjiao (SP 6), on the affected side, were chosen for stimulation. In the HESPT group, tenderness points, the main points of Liangqiu (ST 34), Xuehai (SP 10), Neixiyan (EX-LE4), Waixiyan (EX-LE5) and Zusanli (ST 36), and the adjunct points of Yinlingquan (SP 9), Weizhong (BL 40) and Chengshan (BL 57), were chosen. After proper manipulation, Corydalis decumbens Pers. liquid was injected into the points and a high-frequency electric sparkle was applied to stimulate the needles for 30 seconds. In the point-injection group, point injection was performed with the same method, but the patients did not receive electric stimulation. The Western Ontario and McMaster University Osteoarthritis Index (WOMAC), the Lysholm Knee Score Scale (LKSS) and the ROM (Range of Motion) scale were used to evaluate the severity of KOA and the function of knee joints before treatment and 4 weeks after treatment. Finally, the Nimodipine method was used to assess the total curative effect. Results: After HESPT treatment, the scores for pain, morning stiffness and swelling were significantly lower (P<0.01) and LKSS index and ROM were much higher (P<0.01 and P<0.05 respectively) compared to the two other groups. The obviously effective rate and total effective rate were also significantly higher in the HESPT group than in the two other groups (P<0.01 or P<0.05). Conclusion: HESPT can improve joint function in KOA patients, and the curative effect is better than for warming needle moxibustion or point-injection 展开更多

We report a straightforward method via spray printing to fabricate a consecutive ultra-thin LM film on various product substrates. Then, the flexible LM film was coated with a transparent varnish layer, which was rather convenient for the LM paint to be storing, using and transporting. The thicknesses(25 μm) and the shapes of LM paint were well controlled. The flop index(FI=105), and reflectance(R=88.8%) data of the LM metallic paint were characterized. The results indicated that the LM metallic paint could provide a sparkling appearance and an abounding glossy. The deoxidized LM has a pronounced positive influence on the surface roughness, appearance, reflectance,and metallic texture. The LM metallic paint was highly desirable for potential applications in automotive enamel, motorcycle,toy and high-quality industrial coatings in the near future.展开更多

These structures and the Nd-O distances agreed well with those experimentally found in the crystal structures. Replacing the water molecule with a fluoride ion or a mondentatecarbonato ligand resulted in a nonacoordinated distorted square antiprismatic structures where the trans-carbonato groups were twisted. The corresponding decacoordinated structures with two fluoride ions or a bidentatecarbonato group, [Nd(CO3)4·F2]7-and [Nd(CO3)5]7-, were also investigated. In both cases considerable twisting of the transcarbonato groups was observed.展开更多
