Abstract
OBJECTIVE To clarify the expression and underlying network of long non-coding RNA (lncRNA) MCM3AP-AS1 in osteoarthritis (OA). METHODS Human articular cartilage samples, OA model rats and IL-1β-treated C28/I2 cells were used in this study. The expression changes of genes and proteins were assessed by real-time quantitative PCR (qRT-PCR) and western blot. Cell viability, apoptosis, autophagy and extracellular matrix (ECM) degradation were assessed by Cell Counting Kit-8 (CCK-8), immunohistochemistry (IHC), flow cytometry, immunofluorescence and western blot assays, respectively. Molecule interactions were validated by dual luciferase and Chromatin immunoprecipitation (ChIP) assays. H&E staining was used to detect the pathological changes of cartilage. RESULTS MCM3AP-AS1 was upregulated in OA patients and IL-1β-induced chondrocytes. Knockdown of MCM3AP-AS1 enhanced autophagy, while alleviated ECM degradation and cartilage injury. Mechanistically, overexpression of SOX4 boosted the transcription of MCM3AP-AS1. Moreover, MCM3AP-AS1 functioned as a molecular sponge or epigenetic regulator of miR-149-5p to facilitate Notch1 expression. Functional rescue experiments showed that either inhibition of miR-149-5p nor ectopic expression of Notch1 dramatically weakened the biological impacts of MCM3AP-AS1 silencing. CONCLUSION These finding demonstrated that SOX4-activated MCM3AP-AS1 aggravated OA progression by modulating autophagy and ECM degradation via targeting miR-149-5p/Notch1 axis. These data supported that inhibition of MCM3AP-AS1 might be a potential treatment strategy of OA.

Abstract
As a pharmaceutical plant with multi-bioactivity, Ageratum conyzoides appears to be a valuable agricultural resource. In this study, the complete mitochondrial (mt) genome of A. conyzoides was sequenced through Illumina sequencing method, and the mt genome was recovered after de novo assembly and annotation. The results showed that the 219,198 bp mt genome has a total of 52 genes, including 30 protein-coding genes, 3 rRNA genes and 19 tRNA genes. The overall GC content of this mitogenome is 45.4%. By phylogenetic analysis using maximum-likelihood (ML) method, A. conyzoides showed the closest relationship with Diplostephium hartwegii in the family of Asteroideae.

Abstract
Four natural compounds were obtained by concentrating, separating and purifying from the Folium isatidis. These natural compounds have been characterized by elemental analysis, IR spectrum, NMR and single-crystal X-ray diffraction analysis. The results show that these natural compounds are 4(3H)-quinazolinone (I), 2,4(1H,3H)-quinazolinedione (II), methyl 3,4-dihydro-4-oxoquinazoline-2-carboxylate (III) and ethyl 3,4-dihydro-4-oxoquinazoline-2-carboxylate (IV). The antibacterial activity experiment showed that I and II had better activity against Staphylococcus aureus, Escherichia coli, Bacillus subtilis and Salmonella than III, IV and other multiple components, because III and IV have long branches and steric hindrance effect. Compounds I and II have planar structure, which can more easily combine with these bacteria and kill them. The above results have good guiding significance for studying the antibacterial activity for single components or mixtures from natural origin.
