Diamond-like carbon (DLC) films on ultra-high molecular weight polyethylene substrates were prepared at CHn+ ion bombarding energies of 200-1000eV at room temperature using ion beam assisted deposition technique. The wear tests exhibited a high wear resistance for all DLC films. X-ray photoelectron spectfoscopy and raman spectroscopy analysis indicated that DLC film was amorphous with a characteristic high fracdion of sp3 bonds in the structure of mixed sp:2+ sp3 bonding at an optimal bombardingenergy of 600eV.

The title compound (C28H21ClN2O, Mr = 436.92) was synthesized by the cross- photodimerization of (E)-2-(2-phenylethenyl)benzoxazole and (E)-4-[2-(4-chlorophenyl)ethenyl]- pyridine in sulfuric acid solution. Its molecular structure has been unequivocally determined by X-ray crystallography. The title compound belongs to triclinic system, space group p?with cell parameters: a = 9.648(3), b = 10.458(4), c = 12.106(4) , a = 89.089(7), b = 75.644(6), g = 68.441(7)? V = 1096.7(7) 3, Z = 2, Dc = 1.323 g/cm3, F(000) = 456 and m(MoKa) = 0.198 mm-1. The final r and wr are 0.0627 and 0.1285, respectively for 1737 observed reflections with I > 2s(I). S = 0.921 and (/s)max = 0.001. The cyclobutane ring has a puckered conformation with four different aryl groups substituted on each carbon atom. The dihedral angles of the cyclobutane ring are 20.2 and 20.6? The bond distances of the cyclobutane ring are 1.541, 1.555, 1.560 and 1.563 ? respectively, which are slightly longer than that of the normal CC single bond. The title compound is the only cross-dimer and its two heteroaryl groups are situated at the trans-1,3 position of the cyclobutane ring, revealing that the cross-photodimerization proceeds in a head-to-tail pattern with high stereo-selectivity.

Dyschromatosis symmetrica hereditaria(DSH) is a rare autosomal dominantly inherited dermatosis and characterized by a mixture of hyperpigmented and hypopigmented macules on the back of hands and *** DSH locus was mapped to chromosome 1q21 and subsequently pathogenic mutations were identified in the adenosine deaminase acting on rNA1(ADAr1) gene in 2003.A large Chinese family with autosomal dominance DSH was *** analysis revealed linkage of the family to the *** exons and exon-intron boundaries of ADAr1 were pCr-amplified and sequenced with DNA samples from the *** fragment length polymorphism(rFLp) analysis for intron 7-exon 8 boundary of ADAr1 was performed in all family members and 100 normal control subjects.A novel splicing mutation IVS7-2A>C was detected in the ADAr1 *** mutation was present in other affected family members,but not in other normal family members and 100 normal *** in vitro splicing assay using HeLa cells transfected with expression vectors containing the normal or the mutant ADAr1 minigenes consisting of genomic fragments spanning exon 7 to exon 10 showed that the IVS7-2A>C mutation caused abnormal splicing,leading to severely truncated ADAr1 *** results indicate that the novel IVS7-2A>C mutation in the ADAr1 gene is responsible for DSH in the Chinese family,this study expands the spectrum of ADAr1 gene mutations associated with DSH,which have further improved our understanding on the role of ADAr1 in DSH.

Under hydrothermal conditions,Sm(ClO)(or Gd(ClO))reacted with 3,5-pyridinedicarboxylic acid(3,5-pDCH)under 170℃ to give a 3-D coordination polymer with the empirical formula of [Sm(3,5-pDC)(CO)(HO)]·HO(1),[Gd(3,5-pDC)(CO)(HO)]·HO(2).The structures of both polymers have been determined by X-ray diffraction,and characterized by TG and Ir *** two crystals of complexes are both belong to Monoclinic space group p2(1)/n, with the complex(1)a=7.6582(6)(?), b=9.8602(8)(?),c=14.8640(2)(?), V=1110.48(2)(?),Z=4,F(000)=792.0, Goof=1.038,Mu=5.335 mm,Final r indices [Ⅰ＞2sigma(Ⅰ)]:r1=0.0368,wr2=0.0928;the compound(2)a=7.6400(2)(?), b=9.8448(3)(?),c=14.8206(5)(?), V=1102.92(6)(?),Z=4,F(000)=799.81, Goof=1.073,Mu=6.060 mm,Final r indices [Ⅰ＞2sigma(Ⅰ)]:r1=0.0191,wr2=*** molecular structure such as Fig.1.X-ray structure analyses show that both polymers contain bridging oxalate(CO)ligands,which might have been formed by the reductive coupling of CO molecules released from the pDCligands through the C-C bond cleavage.

目的:探讨宫颈鳞癌中血管内皮生长因子受体-3(VEGFr-3)及D2-40标记的微淋巴管密度(MLVD)与宫颈鳞癌临床病理及淋巴转移的关系,为临床预测宫颈鳞癌淋巴转移提供有意义的实验依据。方法:用免疫组化p-V二步法检测11例正常宫颈,15例宫颈上皮内瘤变(CIN)及63例宫颈鳞癌组织中的VEGFr-3表达及D2-40标记的MLVD;采用SpSS17.0统计软件包进行统计学处理,并建立预测宫颈鳞癌淋巴转移的rOC曲线。结果:①正常宫颈、CIN及宫颈鳞癌3组中,VEGFr-3的阳性表达率分别为0、6.67%和74.60%,差异有高度统计学意义(χ2=37.20,p=0.000);D2-40标记的MLVD分别为1.55±1.04,7.40±2.87和17.14±5.53,3组比较差异有高度统计学意义(H=48.731,p=0.000)。②VEGFr-3的高表达率在有淋巴转移组明显高于无淋巴转移组(χ2=26.963,p=0.000);D2-40标记的MLVD与组织学分级、间质浸润深度及淋巴转移有关(p均(0.05)。③VEGFr-3表达强度与D2-40标记的MLVD呈正相关(r=0.757,p=0.001)。④当VEGFr-3的表达强度≥1.5,D2-40标记的MLVD≥18.50,两者联合≥18.50时均有预测宫颈鳞癌淋巴转移的意义(曲线下面积分别为:0.850、0.894、0.901,p均=0.000)。结论:VEGFr-3的表达可能参与宫颈鳞癌的发生、发展和淋巴转移;检测VEGFr-3表达和D2-40标记的MLVD对预测宫颈鳞癌淋巴转移有一定的参考意义。
