AbstractThis study investigated the differential metabolites after rheumatoid arthritis (RA) rats were treated with Jinteng Qingbi granules. Collagen‐induced arthritis rats were divided into three groups, namely normal group, model group, and Jinteng Qingbi granules group. Serum compounds were identified, annotated, and classified using metabolomics to explain the physicochemical properties and biological functions. The metabolites were screened using univariate and multivariate statistical analyses. There were differences in serum metabolites between RA and normal rats; Jinteng Qingbi granules improved RA and recovered the metabolite levels to normal. Compared to the normal group, 51 differential ions were screened, and 108 ions were changed in the Jinteng Qingbi granules group compared to the RA model. Eight metabolites were upregulated in the RA model group compared to the normal group, whereas 10 metabolites were downregulated. Treatment with Jinteng Qingbi granules increased the levels of 12 metabolites such as cinnamate and decreased the levels of 16 metabolites such as allamandin in the RA model. Differential ion enrichment was mainly related to the histidine metabolic pathway in amino acid metabolism. Jinteng Qingbi granules resulted in improvements in the RA model, which were mainly associated with lipids and lipid‐like molecules, organic acids, and derivatives, providing a new possibility and basis for screening biomarkers for the diagnosis and treatment of RA.

This study aimed to further explore the relevant mechanism of action by network pharmacology integrated with animal experimental verification based on previous proven effective treatment of vertebral artery type of cervical spondylosis(CSA) by Panlongqi Tablets. Bionetwork analysis was performed to establish drug-disease interaction network, and it was found that the key candidate targets of Panlongqi Tablets were enriched in multiple signaling pathways related to CSA pathological links, among which phosphatidylinositol 3-kinase(PI3 K)/serine-threonine kinase(AKT/PKB) signaling pathway was the most significant. Further, mixed modeling method was used to build the CSA rat model, and the rats were divided into normal, model, Panlongqi Tablets low-, medium-and high-dose(0.16, 0.32, 0.64 g·kg~(-1)) and Jingfukang Granules(positive drug, 1.35 g·kg~(-1)) groups. After successful modeling, the rats were administered for 8 consecutive weeks. Pathological changes of rat cervical muscle tissues were detected by hematoxylin-eosin(HE) staining, and the content of interleukin-1β(IL-1β), tumor necrosis factor-α(TNF-α), vascular endothelial cell growth factor(VEGF) and chemokine(C-C motif) ligand 2(CCL2) in rat serum and/or cervical tissues was determined by enzyme-linked immunosorbent assay(ELISA). Western blot was employed to detect the protein expression levels of chemokine(C-C motif) receptor 2(CCR2), PI3 K, AKT, phosphorylated AKT(p-AKT), I-kappa-B-kinase beta(IKK-beta/IKKβ), nuclear factor kappa B(NF-κB P65) and phosphorylated nuclear factor kappa B(NF-κB p-P65) in rat cervical tissues, and positive expression of p-NF-κB P65 in rat cervical muscle tissues was detected by immunofluorescence. The results showed that Panlongqi Tablets at different doses improved the degree of muscle fibrosis and inflammation in cervical muscle tissues of CSA rats, and reduced the content of inflammatory factors IL-1β, TNF-α, VEGF, CCL2 and CCR2 in serum and/or cervical tissues. The protein expression levels of PI3 K, p-AKT, IKKβ and p-NF-κB P65 as well as the nuclear entry of p-NF-κB P65 in cervical tissues were down-regulated. These findings suggest that Panlongqi Tablets can significantly inhibit the inflammatory response of CSA rats, and the mechanism of action may be related to the down-regulation of the activation of PI3 K/AKT signaling pathway.

BACKGROUNDMetastasis is the main cause of lung cancer death. As a seed of metastasis, circulating tumor cells are an important target for metastasis intervention. The traditional Chinese medicine, Jinfukang, has been clinically available for the treatment of non-small cell lung cancer (NSCLC). In this study, we investigated the action and underlying mechanisms of Jinfukang against circulating lung tumor cells.METHODSThe cell counting kit-8 (CCK-8), colony formation and cell cycle assays were used to study the cell proliferation ability. Flow cytometry was used to detect the apoptosis and the expression level of ROS and Caspase-3. Comet and TUNEL assays were used to detect DNA damage. DNA damage related pathway protein was detected by western blot.RESULTSJinfukang significantly inhibits the proliferation of CTC-TJH-01 cells by inducing G1 phase arrest and inhibits their colony formation in a dose-dependent manner. Moreover, Jinfukang induces apoptosis in CTC-TJH-01 cells through the ROS-mediated ATM/ATR-p53 pathway and DNA damage.CONCLUSIONSOur findings suggest that Jinfukang may be a potential drug for lung cancer metastasis.
