The short video industry has overgrown due to the digital transformation of media communication. The dissemination of short videos has led to the "two-way communication" of rural regional culture in the state and abroad. Many scholars have conducted in-depth studies on short video dissemination and discourse expression. On the basis of these studies, this paper takes Xi Jinping's important statement on the development of media integration and the construction of regional culture as the core point. This paper mainly adopts the literature analysis method. The study shows that rural short videos, as the leading force in the era of We-Media, connect local culture and local specialties through the Internet and contribute to the revitalization of the countryside in the fields of culture and economy. At the same time, media reality interacts with social reality through short rural videos, which perpetuates the rural memory of the public. The research suggests that short video creators should improve their own quality and optimize short video content. Creators should also pay attention to the use of expressions in line with the norms of public discourse in short videos, so as to achieve a positive interaction between media reality and social reality.

In this study, 6-aryl-5-cyanopyrimidines and quinazolinones were introduced into panaxadiol (PD) to synthesize 25 new panaxadiol derivatives. The cytotoxicity of these compounds against three cancer cells and one normal cell was examined by methylthiazoletetrazolium (MTT) cytotoxicity experiment. The findings demonstrated that PD cyanopyrimidine derivatives have superior anti-proliferative effects over quinazoline derivatives. Among them, PM14 had the strongest inhibitory activity on the proliferation of human hepatoma cell lines (HepG-2), the IC

BACKGROUND COVID-19 was first reported in 2019, and the Chinese government immediately carried out stringent and effective control measures in response to the epidemic. OBJECTIVE Nonpharmaceutical interventions (NPIs) may have impacted incidences of other infectious diseases as well. Potential explanations underlying this reduction, however, are not clear. Hence, in this study, we aim to study the influence of the COVID-19 prevention policies on other infectious diseases (mainly class B infectious diseases) in China. METHODS Time series data sets between 2017 and 2021 for 23 notifiable infectious diseases were extracted from public data sets from the National Health Commission of the People’s Republic of China. Several indices (peak and trough amplitudes, infection selectivity, preferred time to outbreak, oscillatory strength) of each infectious disease were calculated before and after the COVID-19 outbreak. RESULTS We found that the prevention and control policies for COVID-19 had a strong, significant reduction effect on outbreaks of other infectious diseases. A clear event-related trough (ERT) was observed after the outbreak of COVID-19 under the strict control policies, and its decreasing amplitude is related to the infection selectivity and preferred outbreak time of the disease before COVID-19. We also calculated the oscillatory strength before and after the COVID-19 outbreak and found that it was significantly stronger before the COVID-19 outbreak and does not correlate with the trough amplitude. CONCLUSIONS Our results directly demonstrate that prevention policies for COVID-19 have immediate additional benefits for controlling most class B infectious diseases, and several factors (infection selectivity, preferred outbreak time) may have contributed to the reduction in outbreaks. This study may guide the implementation of nonpharmaceutical interventions to control a wider range of infectious diseases.
