We study block-coherence measures based on the resource theory of block-coherence and coherence measures based on positive-operator-valued measures(POVM).Several blockcoherence measures are presented,including the block-coherence measure based on maximum relative entropy,the one-shot block-coherence cost under maximally block-incoherent operations,and the coherence measure based on coherent *** relationships are ***,we describe the deterministic coherence dilution process by constructing blockincoherent *** on the POVM coherence resource theory,we also propose two coherence measures and analyze their relationship.

· AIM: To investigate the expression of complement factors in the posterior scleral fibroblasts of guinea pigs with negative lens-defocused myopia.· METHODS: Eighteen guinea pigs were assigned randomly to two groups: the negative lens-defocused group(NLD group, n =9) and the normal control without treatment group(NC group, n =9). The effect of myopic induction was compared in three subgroups: eyes treated with a-10.00 D negative lens in the NLD group(NL group), eyes treated with a plano(0 D) lens in the NLD group(PL group), and untreated right eyes in the NC group(NC group). The following analyses were conducted at four weeks: examination of the refractive error via retinoscopy, assessment of complement C5b-9expression in the posterior scleral fibroblasts using immunohistochemistry, and measurements of complement C1 q and C3 protein levels in the posterior sclera by Western blot.·RESULTS: After an induction period of four weeks, a significant myopic shift was detected in the eyes of the NL group, relative to that of the PL and NC groups(P <0.05). Data analysis showed a significant increase in the percentage of C5b-9 immunopositive fibroblasts in the posterior sclera of the NL group eyes, compared to the PL group(q =11.50, P <0.001). Significantly higher levels of C1q(q =4.94, P =0.01) and C3(q =4.07, P =0.03)protein were detected in the posterior sclera of NL group eyes, compared to the PL group. There were no significant difference between the PL and NC groups for C5b-9(q =2.44, P =0.10), C1q(q =1.55, P =0.53) and C3(q =0.98, P =0.77) in the posterior sclera.·CONCLUSION: The data from present study provide evidence of the up-regulation of C5b-9, C1 q and C3 in the posterior scleral fibroblasts in a NLD myopic animal model. The results suggest that the complement system may be involved in the development of myopia.

背景:在临床上,大多数治疗早发性卵巢功能不全的方剂均以六味地黄丸为基础方演变而来,并且取得了较好的疗效。目前对六味地黄丸的实验研究大多为体内动物模型的形态学观察及生理生化指标的检测,而分子机制方面的研究报道较少。目的:探讨六味地黄丸治疗早发性卵巢功能不全的分子作用机制。方法:环磷酰胺120 mg/kg联合白消安12 mg/kg腹腔注射制备早发性卵巢功能不全小鼠模型,然后用六味地黄丸混悬液对早发性卵巢功能不全小鼠进行干预,干预12周采用ELISA法检测小鼠血清中促卵泡刺激素、促黄体生成素、雌激素、抗苗勒氏管激素、8-羟脱氧鸟苷、总抗氧化能力、活性氧水平;苏木精-伊红染色观察小鼠卵巢形态学改变;透射电镜观察小鼠卵泡颗粒细胞超微结构及颗粒细胞线粒体的凋亡情况;免疫组化法检测六味地黄丸对小鼠卵巢颗粒细胞中核受体转录辅激活因子(receptor gamma coactivator-1 alpha,PGC-1α)、线粒体转录因子A(mitochondrialtranscriptionfactorA,TFAM)的表达水平。结果与结论:①与模型组比较,实验组小鼠血清促卵泡刺激素、促黄体生成素、活性氧、8-羟脱氧鸟苷水平降低(P<0.05),雌激素、抗苗勒氏管激素、总抗氧化能力水平升高(P<0.05);②苏木精-伊红染色发现模型组小鼠卵巢组织中闭锁卵泡和黄体较多,个别可见次级卵泡,间质纤维化增生;实验组小鼠卵巢组织可见大量闭锁卵泡,黄体较少,边缘可见原始卵泡,次级卵泡较少,未见明显成熟卵泡;③透射电镜发现实验组小鼠卵巢颗粒细胞内细胞器较完整;④免疫组化结果显示,实验组小鼠卵巢组织PGC-1α的表达水平在第4周稍有升高至第8,12周无明显变化,与模型组有明显差异;实验组小鼠卵巢组织TFAM的表达水平在第4周时短暂升高,然后稍有所下降,但结果均与模型组有明显差异;⑤结果表明,六味地黄丸通过PGC-1α-TFAM-ROS信号通路在一定程度上抑制早发性卵巢功能不全小鼠卵巢颗粒细胞凋亡,从而改善卵巢的内分泌功能,提高机体抗氧化能力,减轻氧化应激损伤程度。

目的:考察在初始资源不对等情境下4-7岁儿童的公平分配行为差异以及视角水平在其中的作用。方法:采用完全被试间设计,在第一方任务中向364名4-7岁儿童呈现平均分配、自利分配、公平分配、利他分配4种分配方案。结果:视角水平对儿童的公平行为有显著影响;相较于优势视角,4-7岁儿童在劣势视角下会更加注重公平;性别并不影响儿童的公平行为。结论:儿童公平分配行为因视角情境存在发展差异。随着年龄发展,儿童从简单的平分但结果不公平的分配逐渐过渡到通过不平等分配来实现结果公平的分配;儿童自利分配随着年龄呈递减趋势。
