The fall armyworm (FAW), Spodoptera frugiperda, is a destructive pest native to America and has recently become an invasive insect pest in China. Because of its rapid spread and great risks in China, understanding of FAW genetic background and pesticide resistance is urgent and essential to develop effective management strategies. Here, we assembled a chromosome-level genome of a male FAW (SFynMstLFR) and compared re-sequencing results of the populations from America, Africa, and China. Strain identification of 163 individuals collected from America, Africa and China showed that both C and R strains were found in the American populations, while only C strain was found in the Chinese and African populations. Moreover, population genomics analysis showed that populations from Africa and China have close relationship with significantly genetic differentiation from American populations. Taken together, FAWs invaded into China were most likely originated from Africa. Comparative genomics analysis displayed that the cytochrome p450 gene family is extremely expanded to 425 members in FAW, of which 283 genes are specific to FAW. Treatments of Chinese populations with twenty-three pesticides showed the variant patterns of transcriptome profiles, and several detoxification genes such as AOX, UGT and GST specially responded to the pesticides. These findings will be useful in developing effective strategies for management of FAW in China and other invaded areas.

Rhythm of blood pressure refers to the circadian variation of blood pressure, which is regulated by clock genes. However, the rhythm disorder of blood pressure increases the risk of stroke. Taking the process of blood pressure regulation as a clue and focusing on the clock gene pathway, this article explores the possible mechanism of period gene regulating renin-angiotensin-aldosterone system in rhythm of blood pressure, so as to provide reference for the in-depth study of the relevant mechanism of rhythm disorder of blood pressure and search for a new target for the primary prevention of cerebrovascular diseases.

Licorice has long been regarded as one of the most popular herbs, with a very wide clinical application range. Whether being used alone or as an ingredient in prescription, it has an important role which cannot be ignored. However, the efficacy and chemical constituents of licorice will change after honey-processing. Therefore, it is necessary to find quality markers before and after honey-processing to lay the foundation for a comprehensive evaluation of the differences between raw and processed licorice pieces. HPLC-DAD was employed to establish fingerprints of raw and processed licorice. Multivariate statistical analysis methods including principal component analysis(PCA) and orthogonal partial least squares discrimination analysis(OPLS-DA) were applied to screen out the differential components before and after processing of licorice. Based on network pharmacology, the targets and pathways corresponding to the differential components were analyzed with databases such as Swiss Target Prediction and Metascape, and the "component-target-pathway" diagram was constructed with Cytoscape 3.6.0 software to predict the potential quality markers. A total of 17 common peaks were successfully identified in the established fingerprint, and seven differential components were selected as potential quality markers(licoricesaponin G2, glycyrrhizic acid, liquiritigenin, liquiritin, isoliquiritin, liquiritin apioside and isoliquiritigenin). The HPLC fingerprint method proposed in this study was efficient and feasible. The above seven differential chemical components screened out as potential quality markers of licorice can help to improve and promote the overall quality. These researches offer more sufficient theoretical basis for scientific application of licorice and its corresponding products.

There are many chemical components in the volatile oil of Dictamni Cortex. The complex network relationship of "component-target-disease" can be revealed by using the network pharmacology method, and the mechanism of the efficacy of Dictamni Cortex can be revealed. In this study, we used Swiss Target Prediction database to predict the target of action, STRING database to build protein interaction network, and Cytoscape software to build "component-target-disease" network. The results showed that the antibacterial, anti-inflammatory and antiallergic effects of Dictamni Cortex were closely related to the components of thymol methyl ether, elemenol, anethole, and the related targets of each component were cross-linked to play a multi-target pharmacodynamic role. This study laid a foundation for the study of the effective substance basis and quality control evaluation of the Dictamni Cortex, and provided a scientific basis for further revealing its mechanism.
