防己黄芪汤对脾虚小鼠Mψ,T细胞功能的影响

观察防己黄芪汤经灌胃给药后对脾虚小鼠腹腔巨噬细胞和脾脏Ｔ细胞功能的影响。方法：采用噻唑蓝比色法测定Ｍψ右噬细胞活性及其分泌ＩＬ－１的能力、Ｔ细胞增殖活性及其分泌ＩＬ－＝２的能力。结果：脾虚小鼠Ｍψ、Ｔ细胞功能均明显降低，而防己黄芪汤对上述４项免疫指标下降表现出明显对抗作用     

大豆异黄酮改善阿尔茨海默病大鼠学习记忆能力的机制

目的 探讨大豆异黄酮(soybean isoflavones，SIF）改善阿尔茨海默病（Alzheimer''s disease，AD）大鼠学习记忆能力的机制。方法 将70只大鼠随机分为正常对照组，假手术组，模型组，雌激素组和高、中、低剂量SIF治疗组，采用右侧杏仁核注射β-淀粉样肽（β-amyloid peptide，Aβ）25-35复制AD大鼠模型，给予不同剂量的SIF，通过检测逃避潜伏期、游泳时间百分比和2 min内穿过平台次数评价大鼠学习记忆能力，观察并比较各组大鼠海马胆碱乙酰转移酶（choline acetyltransferase，ChAT）活性和半胱天冬氨酸特异性蛋白酶3（cysteinyl aspartate specific protease-3，caspase-3）的活性。结果 与模型组比较，高、中、低剂量SIF组逃避潜伏期显著降低(P<0.01），游泳时间百分比和穿过平台次数显著增加（P<0.01），高、中剂量SIF组大鼠海马ChAT活性显著升高(P<0.01），各剂量SIF组AD大鼠海马caspase-3活性显著降低（P<0.01）。高、低剂量SIF组逃避潜伏期、2 min内穿过平台次数、ChAT活性和caspase-3活性比较，差异具有统计学意义（P<0.01）。结论 大豆异黄酮通过调节AD大鼠海马ChAT和caspase-3活性，改善其学习记忆能力，并呈现一定的量效关系。     

老年流动人口就业质量及其影响因素研究

在国家实施新型城镇化战略和积极应对老龄化的社会背景下，探究老年流动人口就业状况，全 面提升老年流动人口就业质量，已成为社会经济转型时期推动高质量发展的迫切任务。研究利用 2017 年全国流 动人口动态监测数据，从职业类型、单位性质、行业分布等方面考察了老年流动人口的就业状况，并探讨了就 业质量指数的影响因素。研究发现：老年流动人口就业呈现出工作时间长、收入少、层次低、环境差等特点； 老年流动人口的就业质量指数低于劳动年龄流动人口且群体内部存在差异；教育经历增加、社会参与增多和非 农户籍会对老年流动人口就业质量产生正向影响，且对受雇和自雇老年流动人口就业质量的影响存在差异。研 究建议：要完善老年人就业服务体系建设，对从业老年流动人口进行“扶智”“赋能”和“扶助”，从而改善 老年流动人口的就业状况，提高其就业质量。     

Dynamics of governance,gross capital formation,and growth: Evidence from Brazil,Russia, India,China, and South Africa

This study investigates the impact of governance index and gross fixed capital formation on the economic growth of Brazil, Russia, India, China and South Africa (BRICS) using annual data from 2002 to 2019. This study employs Fixed Effect Model, Driscoll and Kraay standard error with fixed effect, Fully Modified Ordinary Least Square, Dynamic Ordinary Least Square (DOLS) and Panel Dumitrescu Hurlin Causality test. The study has divided the variables into two models where model I includes the impact of governance index (jointly) on economic growth while model II examines the impact of governance index on economic growth individually. The findings demonstrate that the governance index, gross fixed capital formation, population, control of corruption, and governance effectiveness have a positive and significant impact on economic growth, whereas regulatory quality showed a significant and negative impact on economic growth. Furthermore, regarding the Panel test, we notice the presence of unidirectional causality among the constituent variables. Therefore, this study suggests that the government should encourage economic development in the BRICS countries and move away from outdated ideas and poor institutional quality in favor of a new comprehensive reform to achieve excellent governance, population growth control, labor law changes, and corruption control.     

Principles of the Ukrainian social welfare system in the context of European integration

At the stage of the development of a new social welfare system in Ukraine, it is important to investigate all possible models and develop recommendations for the implementation of the most effective ones. The relevance of this paper lies in the study of the legal framework that operates in Ukraine and the possibilities of its improvement and consolidation into a more specific regulation. The purpose of the research was to study the principles of the social welfare system in Ukraine and to study foreign practices of the social welfare system. Within the framework of this study, the existing systems and models of social welfare systems in different countries were analyzed. The study identifies the most positive examples of social welfare policy for implementation in the current legal framework to improve and enhance the quality of social services in Ukraine. The analyzed foreign practices helped to identify the most effective models of social security. It was concluded that with the successful redistribution of funds, the introduction of a system of audit and control of social assistance financing, as well as being guided by foreign experience, Ukraine will be able to build a social welfare system that would satisfy all of the existing social needs of citizens.
