为改善石磨全麦挂面品质,以石磨全麦粉为主要原料,选择全麦粉粒度、食盐添加量、熟化时间、加水量为单因素,挂面蒸煮特性、质构特性及感官评分为考察指标,筛选出各因素的最佳水平。在单因素试验基础上,以挂面烹调损失率和感官评分为评... 为改善石磨全麦挂面品质,以石磨全麦粉为主要原料,选择全麦粉粒度、食盐添加量、熟化时间、加水量为单因素,挂面蒸煮特性、质构特性及感官评分为考察指标,筛选出各因素的最佳水平。在单因素试验基础上,以挂面烹调损失率和感官评分为评判指标,根据Box-Behnken原理设计四因素三水平试验,以熵权法计算的综合评分作为响应值,优化石磨全麦挂面配方。结果表明,影响石磨全麦挂面综合评分的因素主次顺序为全麦粉粒度>熟化时间>食盐添加量>加水量,石磨全麦挂面最优配方:全麦粉粒度120目,食盐添加量0.85%(质量分数),熟化时间15 min,加水量37.32%(质量分数)。最佳配方下制备的挂面烹调损失率为(6.31±0.11)%,感官评分为(92.33±2.52)分,膳食纤维含量为(10.40±0.22)%,血糖生成指数为(69.37±0.52)。 展开更多

结直肠癌是最常见的癌症之一,过去虽然对早期结直肠癌的治疗已取得了长足进步,但其转移机制尚不清楚,针对结直肠癌的转移尚无有效治疗方法,而远处转移是结直肠癌引起死亡的主要原因。结直肠癌干细胞的存在促进了结直肠癌的发生发展,而... 结直肠癌是最常见的癌症之一,过去虽然对早期结直肠癌的治疗已取得了长足进步,但其转移机制尚不清楚,针对结直肠癌的转移尚无有效治疗方法,而远处转移是结直肠癌引起死亡的主要原因。结直肠癌干细胞的存在促进了结直肠癌的发生发展,而基质细胞与结直肠癌细胞发生物质交换,为结直肠癌细胞提供营养物质,因此结直肠癌干细胞与癌细胞所处的微环境对结直肠癌发生远处转移起着至关重要的作用。未来,对结直肠癌干细胞和微环境的深入研究可以预防和治疗结直肠癌的转移,并为发生远处转移的结直肠癌患者的治疗提供新思路。 展开更多

The lack of descriptions regarding the order of precedence between the local laws of cities with subordinate districts and the regulations of provincial governments in Legislation Law of the People's Republic of China(Legislation Law) has led to two divergent views. One holds that "the local laws of cities with subordinate districts should take precedence over the regulations of provincial governments," while the other supports the exact opposite. This is a value judgment issue in legislation. To reach a solution, we need to clarify the premises based on the characteristics of the laws in question so that a basic common ground can be established for discussion. The first premise for traditional legislation is that a law should be based on experience as well as logic; the second is that the experience of authority subjects, plus the three aspects of logic should outweigh the experience of social subjects, plus the three aspects of logic. With respect to postmodern legislation, the first premise is that experience should override logic, and the second is that the experience of the authority subject should take precedence over that of social subject, with no requirements for logical consistency. Since Legislation Law fal s into the category of postmodern legislation, according to the premises, the argument that the local laws of cities with subordinate districts should take precedence enjoys wider acceptance, but the view is logically challenged in terms of conceptual consistency, system consistency and principle consistency. More studies must be conducted to facilitate the discussion. 展开更多

Xi Jinping's theory on ecological progress expands and deepens Marx's views on ecology and spells out the five dialectics between economic development and ecological conservation, the will of the nation and the will of the people, Chinese characteristics and global approaches, cultural concepts and institutional design, as well as the community of life and the community of shared future for mankind. It carries significance for our time and is weighted with theoretical value. At this stage, learning and studying the dialectics and value orientation of Xi Jinping's theory on ecological progress offers scientific guidance and value-based directions for China's efforts to promote an ecological civilization. 展开更多

The emergence and evolution of poverty follows a pattern.At different developmental stages,poverty takes on different characteristics,which calls for specific anti-poverty policies.Ever since its reform and opening up,China has resorted to three different kinds of anti-poverty policies in succession.By shifting its focus to national economic development,China has lifted itself out of universal poverty.With the policy of development-oriented poverty alleviation,China has mitigated regional poverty.Now,China is on a path to eradicate individual poverty with the policy of targeted poverty alleviation.The future will see China put in place some forward-looking social policies to prevent and reduce new poverty issues. 展开更多
