ObjectiveTo analyze the diversity and structural characteristics of microbial communities in the rhizosphere soil of healthy and diseased Andrographis paniculata and to explore the interactions of soil, plants, and microorganisms during the occurrence of diseases. MethodsThe physicochemical properties of the rhizosphere soil of healthy and diseased A.paniculata were determined, and the composition and diversity of bacterial and fungal communities in the rhizosphere soil were analyzed by Illumina high-throughput sequencing. Furthermore, the correlations between physicochemical properties and microorganisms of the rhizosphere soil were explored. ResultsThe content of total nitrogen, total potassium, and available potassium in the rhizosphere soil of diseased A. paniculata was significantly higher than that of healthy A. paniculata. The alpha diversity and richness (operational taxonomic units) of bacterial and fungal communities in the rhizosphere soil of diseased plants decreased compared with those of healthy plants. The microbial communities in the rhizosphere soil of healthy and diseased A. paniculata showed similar composition but different relative abundance. At the phylum level, the relative abundance of Proteobacteria and Chytridiomycota significantly increased, while that of Bacteroidota significantly decreased in the rhizosphere soil of diseased plants. At the genus level, the relative abundance of Sphingomonas, Pseudomonas, and Bryobacter significantly increased, while that of RB41 showed a significant decrease in the rhizosphere soil of diseased plants. The correlation analysis showed different correlations of microbial phyla with physicochemical properties of the rhizosphere soil between healthy and diseased plants. Organic matter, alkaline nitrogen, available phosphorus, and total potassium were correlated with the relative abundance of some dominant bacterial and fungal phyla in the rhizosphere soil of healthy plants, while available nitrogen and total phosphorus were correlated with the relative abundance of some dominant bacterial and fungal phyla in the rhizosphere soil of diseased plants. ConclusionThere are differences in the diversity and richness of microbial communities in the rhizosphere soil of healthy and diseased A. paniculata. The physicochemical properties of soil may have an impact on the rhizosphere microorganisms of A. paniculata, leading to the development of diseases. The results provide a scientific basis for the prevention and ecological management of A. paniculata diseases.

Objective :
To explore whether chrysophanol(CHR) affects macrophage polarization by promoting mitochondrial biosynthesis through AMPK/PGC-1α pathway.
Methods :
The molecular docking and binding ability of CHR with AMPK and PGC-1α were predicted by Autodock vina software. Human monocytes(THP-1) were induced to M0 macrophages by phorbol myristate acetate(PMA), and to M1 macrophages by lipopolysaccharide(LPS) combined with interferon-γ(IFN-γ), which were set as Control group. M1 macrophages treated with CHR were set as CHR group. M1 macrophages treated with CHR combined with AMPK inhibitor(Compound C) were set as CHR+Compound C group. The mRNA expression levels of M1 macrophage markers(iNOS, CD86) and mitochondrial biosynthesis related genes(PGC-1α, NFR-1, TFAM) were detected by Quantitative real time polymerase chain reaction(qRT-PCR). The expression level of M1 macrophage marker iNOS was detected by immunofluorescence. The protein expression levels of AMPK, p-AMPK and PGC-1α were detected by Western blot.
Results :
The docking results showed that the binding energies of CHR with AMPK and PGC-1α were-8.4 kcal/mol and-7.4 kcal/mol, respectively. qRT-PCR results showed that the in vitro model of M1 macrophages was successfully established. Compared with the Control group, CHR treatment significantly increased the mRNA expression of mitochondrial biosynthesis-related genes PGC-1α, NFR-1, and TFAM(P<0.001). Compared with CHR treatment group, CHR combined with Compound C treatment significantly decreased the mRNA expression levels of mitochondrial biosynthesis-related genes PGC-1α, NFR-1, and TFAM(P<0.05). Immunofluorescence results showed that CHR treatment inhibited the protein expression of iNOS compared with the Control group(P<0.001). Compared with CHR treatment group,CHR combined with Compound C treatment reversed the inhibitory effect of CHR on i NOS protein expression(P<0.05). Western blot results showed that compared with the Control group,the CHR treatment group had significant increase in the protein expression levels of p-AMPK and PGC-1α(P<0.001).Compared with CHR treatment group,CHR combined with Compound C treatment significantly decreased the protein expression levels of p-AMPK and PGC-1α(P<0.05).
Conclusion
Chrysophanol may inhibit macrophage polarization to M1 by activating AMPK/PGC-1α signaling pathway to promote mitochondrial biosynthesis.

Chemotherapy-induced complications, particularly lethal cardiovascular diseases, pose significant challenges for cancer survivors. The intertwined adverse effects, brought by cancer and its complication, further complicate anticancer therapy and lead to diminished clinical outcomes. Simple supplementation of cardioprotective agents falls short in addressing these challenges. Developing bi-functional co-therapy agents provided another potential solution to consolidate the chemotherapy and reduce cardiac events simultaneously. Drug repurposing was naturally endowed with co-therapeutic potential of two indications, implying a unique chance in the development of bi-functional agents. Herein, we further proposed a novel "trilogy of drug repurposing" strategy that comprises function-based, target-focused, and scaffold-driven repurposing approaches, aiming to systematically elucidate the advantages of repurposed drugs in rationally developing bi-functional agent. Through function-based repurposing, a cardioprotective agent, carvedilol (CAR), was identified as a potential neddylation inhibitor to suppress lung cancer growth. Employing target-focused SAR studies and scaffold-driven drug design, we synthesized 44 CAR derivatives to achieve a balance between anticancer and cardioprotection. Remarkably, optimal derivative 43 displayed promising bi-functional effects, especially in various self-established heart failure mice models with and without tumor-bearing. Collectively, the present study validated the practicability of the "trilogy of drug repurposing" strategy in the development of bi-functional co-therapy agents.

Under the “patient-centered” drug regulation concept, the inclusion of patient dimensions in real-world evidence becomes increasingly important. Patient experience data can complement and interpret existing data, generate evidence directly from patients, and achieve patient participation in drug development. Data types include patient-reported outcomes and free-text data, which can be collected autonomously or obtained from databases. Application scenarios involve new drug registration, safety evaluation, and additional indications. In China, applying patient experience data to real-world study mainly faces the following challenges: lack of conditions, standards, and motivation to collect high-quality data, a single type of data, and the difficulty of balancing data security with freedom, etc. It is recommended to issue special guidelines, establish a measurement tool certification process, expand data collection channels, explore data source integration methods, optimize the informed consent mechanism, and establish an evidence synergy mechanism to promote the practical application of the “patient-centered” concept in real-world study of drugs.
