A series of dinuclear platinum(ii) alkynyl complexes [Pt2L2(C[triple bond, length as m-dash]CC6H4R-4)4] (R = H 1, CH32, But3) and unusual tetranuclear Pt(ii)-Ag(i) clusters [Pt2Ag2L(C[triple bond, length as m-dash]CC6H4R-4)6] (R = H, 4; CH3, 5; But, 6), together with novel polymer crystals [Pt2Ag2L(C[triple bond, length as m-dash]CC6H5)6]∞ ([4]∞), were synthesized by a self-assembly reaction between [NBu4]2[Pt(C[triple bond, length as m-dash]CC6H4-R-4)4] and [Ag6L6]6+ (L = 4-(3,5-(diphenylphosphine)phenyl)pyridine). These complexes were characterized by using a range of spectroscopic techniques and complexes 1, 3, 5, and [4]∞ were analysed by X-ray crystallography. Each platinum atom of the Pt(ii)-Ag(i) clusters shows an unusual asymmetric distorted square planar geometry with three alkynyl groups and one bridging L phosphorus atom.

Methods: A multi-center randomized controlled trial was done, three hundred and twenty cases were divided into four groups: electroacupuncture combined with active-blood and dissolve-stasis herbs and rehabilitation training group (group A), electroacupuncture combined with rehabilitation training group (group B), herbs combined with rehabilitation training group (group C) and rehabilitation training group (group D), 80 cases in each group. The following two groups of acupoints were used alternatively in electroacupuncture treatment: the first group including Vasomotor Area, Jianyu (LI 15), Biguan (ST 31), Hegu (LI 4) and Taichong (LR 3); the second group including Motor Area, Quchi (LI 11), Yanglingquan (GB 34) and Shenshu (BL 23).
