Under the context of economic transformation and upgrading and the continued advancement of supplyside reforms in China, the development of the energy industry is confronted with many problems and challenges, such as insufficient energy investment, a shortage of financing channels,and the low participation of social capital. In order to fully mobilize social capital to invest in energy, enhance energy investment efficiency, expand energy financing channels,and increase the vitality of the energy industry, the state has recently issued the Implementing Opinions on Deepening the Reform of Investment and the Financing System in the Energy Industry( "Opinions"). This paper provides a deep interpretation of this document from the perspectives of the background for the investment and financing system reform in the energy industry,the main content of the reform, the problems and challenges confronting the reform,and the expected effects from the reform, and analyzes the objectives, ideas and problems of the reform, in order to effectively promote the investment and financing system reform in the energy industry.

肠易激综合征(irritable bowel syndrome,IBS)是一种常见的功能性肠道疾病,其主要特征包括下腹痛、排便性状、习惯改变等。由于IBS极大降低患者生活质量并给患者造成巨大经济压力,其发病机制及治疗已成为诸多学者的研究重点,被认为是内脏敏感性、胃肠动力异常、肠道感染、精神心理障碍等共同作用的结果。近年有研究表明,蛋白酶激活受体2(protease activated receptor 2,PAR-2)与IBS密切相关,PAR-2通过其活化以及信号通路等多种方式影响IBS的发生发展,本文就以PAR-2与IBS发生的关系进行综述。
