OBJECTIVES To investigate whether negative remodeling(NR) detected by intravascular ultrasound(IVUS) of the side branch ostium(SBO) would affect in-stent neointimal hyperplasia(NIH) at the one-year follow-up and the clinical outcome of target lesion failure(TLF) at the long-term follow-up for patients with left main bifurcation(LMb) lesions treated with a two-stent *** A total of 328 patients with de novo true complex LMb lesions who underwent a 2-stent strategy of percutaneous coronary intervention(PCI) treatment guided by IVUS were enrolled in this study. We divided the study into two phases. Of all the patients, 48 patients who had complete IVUS detection pre-and post-PCI and at the 1-year follow-up were enrolled in phase Ⅰ analysis, which aimed to analyze the correlation between NR and in-stent NIH at SBO at the 1-year follow-up. If the correlation was confirmed, the cutoff value of the remodeling index(RI) for predicting NIH ≥ 50% was analyzed next. The phase Ⅱ analysis focused on the incidence of TLF as the primary endpoint at the 1-to 5-year follow-up for all 328 patients by grouping based on the cutoff value of *** In phase I: according to the results of a binary logistic regression analysis and receiver operating characteristic(ROC) analysis, the RI cutoff value predicting percent NIH ≥ 50% was 0.85 based on the ROC curve analysis, with a sensitivity of 85.7%, a specificity of 88.3%, and an AUC of 0.893(0.778, 1.000), P = 0.002. In phase Ⅱ: the TLR rate(35.8% vs. 5.3%, P < 0.0001)was significantly higher in the several NR(s NR, defined as RI ≤ 0.85) group than in the non-s NR *** The NR of LCx O is associated with more in-stent NIH post-PCI for distal LMb lesions with a 2-stent strategy,and NR with RI ≤ 0.85 is linked to percent NIH area ≥ 50% at the 1-year follow-up and more TLF at the 5-year follow-up.

Let {β（s）,s ≥ O} be the standard Brownian motion in R^d with d ≥ 4 and let ｜Wr（t）｜ be the volume of the Wiener sausage associated with {β（s）, s ≥ O} observed until time t. Prom the central limit theorem of Wiener sausage, we know that when d ≥ 4 the limit distribution is normal. In this paper, we study the laws of the iterated logarithm for ｜Wr（t）｜ - e｜Wr（t）｜ in this case.

Chinese Journal of Structural Chemistry 2006年第10期25卷 1193-1196页

作者： GAO Ling CHENG qing-yan wang yan-Ji Hebei University of Technology Tianjin 300130 China

The coordination polymer {[Co（phth）（phen）（H2O）]·（C2H5OH）}n （phth = phthalate, phen = 1,10-phenanthroline） with formula C22H2OCoN2O6 （Mr = 467.33） was synthesized by the solvothermal method under low temperature, and its crystal structure was determined by singlecrystal X-ray diffraction. The complex belongs to monoclinic system, space group P21/n with a = 12.7352（16）, b = 8.8125（11）, c = 18.677（2） °A, β= 102.633（2）°, V = 2045.3（4）°A^3 Z = 4, Dc= 1.518 g/cm^3,μ = 0.882 mm^-1, F（000） = 964, S = 1.053, the final R = 0.0401 and wR = 0.0984 for 3135 observed reflections （I〉 2σ（I））. Single-crystal X-ray analysis revealed that the Co（Ⅱ） ion is six-coordinated. The cobalt complex forms a one-dimensional chain structure via phthalate bridging ligand. In the cobalt complex, a 3D network structure is formed by π-π stacking interaction of 1,10-phenanthroline as well as intermolecular hydrogen bonding interactions.

A new expression is established for the common solution to six classical linear quaternion matrix equations A 1 X = C 1 , X B 1 = C 3 , A 2 X = C 2 , X B 2 = C 4 , A 3 X B 3 = C 5 , A 4 X B 4 = C 6 which was investigated recently by wang, Chang and Ning （Q. wang, H. Chang, Q. Ning, The common solution to six quaternion matrix equations with applications, Appl. Math. Comput. 195： 721-732 （2008））. Formulas are derived for the maximal and minimal ranks of the common solution to this system. Moreover, corresponding results on some special cases are presented. As an application, a necessary and sufficient condition is presented for the invariance of the rank of the general solution to this system. Some known results can be regarded as the special cases of the results in this paper.
