通过体内和体外实验方法观察依诺肝素对野百合碱导致肝窦阻塞综合征(HSOS)的治疗及其可能机制。结果显示,野百合碱可导致大鼠HSOS,并降低大鼠肝窦内皮细胞的存活率。与野百合碱比较,依诺肝素治疗可减轻野百合碱所致HSOS大鼠的肝窦阻塞,并可提高肝窦内皮细胞的存活率。此外,野百合碱可使大鼠肝脏、肝窦内皮细胞中Slit2、Robo4蛋白质和mRNA表达下降,但依诺肝素能够上调野百合碱所致HSOS大鼠肝脏、肝窦内皮细胞中Slit2、Robo4蛋白质和mRNA的表达。

目的：探讨延续护理干预在出院早产儿中的应用效果。方法选取2014年出院早产儿1200例，采取随机数字表法分为干预组580例和对照组620例，对照组实施常规出院护理宣教，干预组实施出院延续护理，比较两组早产儿家长和医生护士满意度，评价出院后延续护理干预效果。结果干预组早产儿家长满意度、护士满意度、医生满意度分别为（98．23±2．26）％，（97．98±1．98）％，（97．59±2．63）％，均高于对照组，差异有统计学意义（P ＜0．05）。结论延续护理在出院早产儿中提高医护患满意度效果明显，值得临床应用及推广。

A linear alpha -D-(1-->3)-glucan, named PSG, was obtained from the spores of Ganoderma lucidum. The synthesis of positively and negatively charged polyelectrolytes from PSG was developed. Amine groups and carboxymethyl groups were introduced through nucleophilic substitution with 3-chloropropylamine or chloroacetic acid, respectively, Reaction conditions were varied to obtain insight into the influence of variables on the degree of substitution.

Various methods for synthesis of 2-methyl-5,6-(1,4, 7,10,13-pentaoxatridecamethylene)benzotellurazole (8) are described. Under different conditions, alkylation of compound 8 with methyl iodide gave telluronium salt 1,2-dimethyl-5,6-(1,4,7,10,13-pentaoxatridecamethylene)benzotellurazolium iodide (15) or quaternary ammonium salt 2,3-dimethyl-5,6-(1,4,7,10,13-pentaoxatridecamethylene)benzotellurazolium iodide (14) in high yields, repectively. The cyanine dye 3,3'-dimethyl-5,6,5',6'-bis(1,4,7,10,13-pentaoxatridecamethylene)telluracarbocyanine iodide (16) is obtained by condensation of 14 with ethyl orthoformate in acetic anhydride, The visible absorption of the cyanine dye is also discussed.

The effect of austenite ageing on martensite transformation in an iron and nickel alloy was studied. Attention was paid to the variation of dislocation configurations in austenite before martensite transformation, The clusters or precipitates produced during austenite ageing and the alteration of dislocation configurations affect together the consequent martensite transformation. Dispersed fine clusters and precipitates cripple nucleus role of special dislocation configurations and drop M-s. Coarse precipitates make M-g rise again. Densely piled up dislocations in nuclei lead to rise of M-s. All the changes in austenite are of benefit to small martensite plates.

A number of specimens of Ti-51Ni (at. pet) alloy showing reversible shape memory effect (RSME) have been measured as to reversibility and S-lineshape parameter of positron annihilation. It is found that the Ti-51Ni specimens showing good memory effect contain structural defects. Not all specimens including structural defects (or structural imperfection) are able to exhibit good memory effect. The structural defects have to be appropriate in density, neither too much nor too little. With no or too much structural defects a good RSME could not take place. It is fully as important that the structural defects exist as it is for the structural defects to be appropriate in density in order to obtain a good RSME.
