本试验采用腺枝葡萄‘桂黑珍珠4号’(Vitis adenoclona Hand.-Mass,Guiheizhenzhu No.4)为试材,在果实开始转色至完全成熟期采用果穗半遮阴处理,测定相关理化指标,并利用广泛靶向代谢组学技术分析成熟果实代谢物的差异。结果表明,与不遮阴相比,半遮阴处理的果实粒质量下降5.49%,可溶性固形物含量提升1.65%,可滴定酸含量降低5.09%,同时加深了果实的颜色。广泛靶向代谢组分析结果表明,两处理果实中共鉴定出11类、789种代谢物,其中差异代谢物有76种,包括下调表达60种、上调表达16种,而半遮阴处理使全部糖类、大部分有机酸和花色苷类物质含量有所增加。因此果穗半遮阴处理可改善果实的酿酒品质,提升腺枝葡萄的加工潜力。

The relationship between the fine particles emitted after desulfurization and gypsum crystals in the desulfurization slurry was investigated,and the crystallization characteristics varying with the operation parameters and compositions of the desulfurization slurry were *** results showed that the fine particles generated during the desulfurization process were closely related to the crystal characteristics in the desulfurization slurry by comparison of their morphology and elements. With the higher proportion of fine crystals in the desulfurization slurry,the number concentration of fine particles after desulfurization was increased and their particle sizes were smaller,indicating that the optimization of gypsum crystallization was beneficial for the reduction of the fine particle emission. The lower p H value and an optimal temperature of the desulfurization slurry were beneficial to restrain the generation of fine crystals in the desulfurization slurry. In addition,the higher concentrations of the Fe3＋ions and the F- ions in the desulfurization slurry both promoted the generation of fine crystals with corresponding change of the morphology and the effect of the Fe3＋ ions was more *** the application of the desulfurization synergist additive,it was beneficial for the inhibition of fine crystals while the thinner crystals were generated.

We have synthesized two photovoltaic molecules（HEX-3TVT-ID and EH-3TVT-ID） based on vinylenebridged oligothiophene applied as donor for the solution-processable bulk-heterojunction organic solar cells（OSCs）. Vinylene unit was introduced as π-bridge in the oligothiophenes with 1,3-indenedione as end group and 4,4’-dihexyl-2,2’：5’,2’-terthiophene or 3’,4’-di（octan-3-yl）-2,2’：5’,2’-terthiophene as core,respectively. Due to the different substituent positions of the alkyl group relative to the vinylene unit in the terthiophene, HEX-3TVT-ID and EH-3TVT-ID show different optical and electrochemical properties, corresponding to the photovoltaic performance of the OSCs devices. The power conversion efficiency（PCE） of the OSCs based on a blend of HEX-3TVT-ID and PC71BM（1：0.8, weight ratio, 0.5% CN） reached 2.3%. In comparison, the OSCs based on the blend of EH-3TVT-ID and PC71BM in the weight ratio of 1：1 without the additive show a higher PCE of 2.7%, with a typically high VOC of 0.93 V, under the illumination of AM 1.5, 100 mW cm-2.

目的:探讨^(99m)Tc-硫胶体(sulfur colloid,SC)用于早期乳腺癌前哨淋巴结(sentinel lymph node,SLN)活检术的最适注射体积。方法:选择原发性乳腺癌(T_(1~2)N_0M_0)、乳房为中小型-致密型患者150例,按^(99m)Tc-SC注射体积不同分为0.5、1、1.5 mL 3组(每组n=50),术前1 d瘤周深部两点法注射(37 MBq/点),2 h后SPECT显像。比较3组患者腋窝SLN(axillary SLN,ASLN)及内乳SLN(internal mammary SLN,IM-SLN)显像检出率。结果:各组总检出率、ASLN检出率和IM-SLN检出率分别为:96%(48/50)、94%(47/50)、74%(37/50),90%(45/50)、82%(41/50)、68%(34/50),52%(26/50)、32%(16/50)、18%(19/50)。总SLN和ASLN检出率在0.5 mL与1 mL组之间无统计学差异,但0.5 mL与1.5 mL组之间有统计学差异(P=0.001和0.004);IM-SLN检出率在0.5 mL组与其他两组之间有显著性差异(P<0.05)。各组注射疼痛评分分别为3.34±1.02、4.58±1.31和5.06±1.42,疼痛持续时间分别为(3.82±1.64)、(6.00±4.48)和(6.58±4.77)min。0.5 mL组疼痛评分、持续时间显著弱于其他两组(P<0.001)。结论:在中小型-致密型乳房患者中,示踪剂注射体积仅为0.5 mL/点即能获得较好的SLN检出率,且对定位IM-SLN有一定优势;同时小体积注射伴随较少的疼痛感,改善了患者舒适度。
