New eudesmanolides from Artemisia verlotorum and their potential targets of hepatocellular carcinoma by network pharmacology.

Fractionation of the ethanol extract of Artemisia verlotorum led to the identification of eight undescribed eudesmane-type sesquiterpenoids, artemverlolides A-H (1-8). Their structures were determined by spectral analyses (HRESIMS, 1D and 2D NMR, IR, and ECD). Network pharmacology predicted that compounds 1-8 might be target on AURKA, CCNA2, CYP2C19, and EPHX2 with possibly antihepatoma effect from Swiss TargetPrediction and Gene Expression Omnibus database. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses showed that the targets significantly enriched in FoxO signaling pathway. The molecular docking suggested that compound 8 had high binding affinity with AURKA. Furthermore, the interaction between compound 8 and AURKA was determined by Surface Plasmon Resonance (SPR) assay. The result suggested that compound 8 bound to AURKA with KD value of 68.0µM and was consistent with the predicted data, demonstrating that AURKA might be one of acting targets of 8.

[Clinical observation of chiropractic manipulation in the treatment of degenerative scoliosis].

OBJECTIVE: To observe clinical efficacy of chiropractic manipulation in the treatment of degenerative scoliosis (DS). METHODS: From June 2017 to September 2019, 120 patients with degenerative scoliosis were randomly divided into treatment group (60 cases) and control group(60 cases). The patients in treatment group were treated with chiropractic manipulation once every other day for 4 weeks. The patients in control group were treated with eperisone hydrochloride tablets combined with thoracolumbar orthopedic(TSLO)brace, oral eperisone hydrochloride tablets 50 mg three times a day, wearing TSLO brace for not less than 8 hours a day. The course of treatment was 4 weeks. After the patients were selected into the group, visual analogue scale (VAS) and Oswestry Disability Index (ODI) were recorded before treatment, 1, 2, 3, 4 weeks after treatment and 1 month after treatment. The full length X-ray of the spine was taken before and 4 weeks after treatment, and the scoliosis Cobb angle, sagittal vertical axis (SVA) and lumbar lordosis (LL) were measured and compared. The adverse reactions during the treatment were recorded. RESULTS: There were significant differences in VAS and ODI between two groups at each time point after treatment (P<0.001), VAS and ODI at 2 weeks after treatment (PVAS=0.025, PODI=0.032) and 3 weeks after treatment(PVAS=0.040, PODI=0.044) in treatment group were significantly different from those in control group, but there was no significant difference in VAS and ODI at other time points between treatment group and control group (P>0.05). There was significant difference in Cobb angle between treatment group(P=0.010) and control group(P=0.017) after treatment, but there was no significant difference in LL and SVA between treatment group and control group. There was no significant difference in Cobb angle, LL and SVA between two groups before and after treatment. During the treatment, there were 4 mild adverse reactions in the control group and no adverse reactions in the treatment group. CONCLUSION: Chiropractic manipulation can effectively relieve pain and improve lumbar function in patients with degenerative scoliosis. The onset of action is faster than that oral eperisone hydrochloride tablets combined with TSLO brace, and it has better safety and can improve Cobb angle of patients with degenerative scoliosis.
