Abstract：中国高校教育改革不断在发展，书院制教育成为高校的新探索与新尝试，其核心理念在于坚持以人为本，强化通识教育和能力培养，加强师生互动，促使学生自主成长。书院制改革背景下的育人理念与传统育人理念的区别必然要求学生的学业评价制度加强创新。因此，大数据时代学生学业发展自画像评价模式应运而生。

Abstract： [Objective] Synthesis of potential neroprotective agent catalpol perpropionylated derivative (CP-6), and determination of the optimal microwav-assisted synthesis conditions. [Methods] CP-6 was synthesized by microwave-assisted synthesis (MCAS) using catalpol and propionyl anhydride as raw materials and pyridine as solvent and acid-binding agent. It was characterized by FT-IR, HRMS, NMR and assayed for neuroprotective activity by MTT method. [Results] When the molar ratio of propionic anhydride to catalpol is 18, the concentration of catalol in pyridine is 25 g/L, the reaction temperature of microwave reactor is 80 ℃, and the reaction time is 6 h, the yield of CP-6 can reach 98.51%. CP-6 has potential neroprotective activity."
