Can Stringent Government Initiatives Lead to Global Economic Recovery Rapidly during the COVID-19 Epidemic?

This paper investigates the effectiveness of government measures implemented against COVID-19 and the factors influencing a country's economic growth from a global perspective. With the help of the data of the Government Response Stringency Index (GRSI), Google mobility, and confirmed COVID-19 daily cases, we conducted a panel model for 105 countries and regions from 11 March 2020 to 31 June 2021 to explore the effects of response policies in different countries against the pandemic. First, the results showed that staying in residential places had the strongest correlation with confirmed cases. Second, in countries with higher government stringency, stay-at-home policies carried out in the early spread of the pandemic had the most effective the impact. In addition, the results have also been strictly robustly analyzed by applying the propensity score matching (PSM) method. Third, after reconstructing a panel data of 47 OECD countries, we further concluded that governments should take stricter restrictive measures in response to COVID-19. Even though it may also cause a shock to the market in the short term, this may not be sustainable. As long as the policy response is justified, it will moderate the negative effect on the economy over time, and finally have a positive effect.

[Advances in research on chemical composition of Picrorhiza scrophulariiflora and P. kurroa and their biological activities].

At present, 141 compounds have been isolated from Picrorhiza scrophulariiflora and P. kurroa of the Scrophulariaceae plants, including 46 iridoid glycosides, 29 tetracyclic triterpenoids, 25 phenylpropanoids, and 11 phenylethanoid glycosides. Pharmacological studies have demonstrated that they have liver-, heart-, brain-, kidney-, and nerve cells-protecting effects as well as anti-tumor, anti-inflammatory, anti-bacterial, anti-asthma, anti-diabetic, immunomodulatory, and blood lipid-lowering activities. This article reviews the chemical components and pharmacological activities of P. scrophulariiflora and P. kurroa, aiming to provide a basis for the in-depth research, development, and utilization of the two plants.
