Objective To evaluate the safety and efficacy of transcatheter arterial chemoembolization(TACE)combined with lenvatinib and camrelizumab in the treatment of advanced hepatocellular carcinoma(HCC).Methods The clinical data of a total of 63 patients with advanced HCC,who received TACE combined with lenvatinib and camrelizumab(triple therapy)or TACE combined with lenvatinib(dual therapy)at the Jingmen Municipal People's Hospital of China between April 2020 and December 2021,were retrospectively analyzed.Triple therapy group had 30 patients,and dual therapy group had 33 patients.The post-treatment tumor response,disease progression-free survival(PFS),overall survival(OS),and the incidence of adverse drug reactions were recorded.Results The median follow-up period of the two groups was 14 months(range of 4-26 months).Compared with the dual therapy group,in the triple therapy group the objective response rate(ORR)was remarkably higher(83.3%vs.57.6%,P=0.026),the disease control rate(DCR)was obviously higher(93.3%vs.69.7%,P=0.039),the median PFS was significantly longer(8.0 months vs.5.0 months,P<0.01),and the median OS was strikingly longer(24.0 months vs.12.0 months,P=0.004).No statistically significant difference in the incidence of adverse drug reactions existed between the two groups(P>0.05).Conclusion For the treatment of advanced HCC,TACE combined with lenvatinib and camrelizumab is clinically safe and effective.(J Intervent Radiol,2024,32:57-62)

Improving liver regeneration (LR) remains a medical issue, and there is currently a lack of safe and effective drugs for LR. Rhizoma Dioscoreae (SanYak, SY) is a traditional Chinese medicine. However, the underlying action mechanism of SY treatment for LR is yet to be fully elucidated. To explore the mechanism by which SY affects LR, we have conducted a series of methods for network pharmacological analysis, molecular docking, and in vivo experimental validation in mice. Overall, 9 compounds and 30 predicted target genes of SY were found to be associated with the therapeutic effects of LR. Compared with the model group, hematoxylin and eosin staining revealed that the mice with preoperative drug intervention possessed fewer postoperative hepatocyte bubbles and relatively regular morphology. Furthermore, the serum alanine transaminase and aspartate aminotransferase levels were reduced, immunohistochemistry revealed elevated proliferating cell nuclear antigen positivity rate, and Western blotting demonstrated that the phospho-protein kinase B (AKT)/AKT ratio was downregulated and that vascular endothelial growth factor A (VEGFA) expression levels were upregulated. This study explored dioscin, the main active ingredient of SY, and its potential therapeutic effects on LR. It repairs damaged liver following surgery and promotes liver cell proliferation. The action mechanism comprises reducing AKT phosphorylation levels and upregulating VEGFA expression levels. Thus, this study provides a new direction for further research on the mechanism of SY promoting LR.

Eclipta prostrata L.has been used in traditional medicine and known for its liver-protective properties for centuries.Wedelolactone(WEL)and demethylwedelolactone(DWEL)are the major coumarins found in E.prostrata L.However,the comprehensive characterization of these two compounds on non-alcoholic fatty liver disease(NAFLD)still remains to be explored.Utilizing a well-established zebrafish model of thioacetamide(TAA)-induced liver injury,the present study sought to investigate the impacts and mechanisms of WEL and DWEL on NAFLD through integrative spatial metabolomics with liver-specific transcriptomics analysis.Our results showed that WEL and DWEL significantly improved liver function and reduced the accumulation of fat in the liver.The biodistributions and metabolism of these two compounds in whole-body zebrafish were successfully mapped,and the discriminatory endogenous metabolites reversely regulated by WEL and DWEL treatments were also characterized.Based on spatial metabolomics and transcriptomics,we identified that steroid biosynthesis and fatty acid metabolism are mainly involved in the hepatoprotective effects of WEL instead of DWEL.Our study unveils the distinct mechanism of WEL and DWEL in ameliorating NAFLD,and presents a"multi-omics"platform of spatial metabolomics and liver-specific transcriptomics to develop highly effective compounds for further improved therapy.

Objective:To retrospectively compare the clinical efficacy of percutaneous vertebroplasty and biopsy by unilateral and bilateral pedicle approaches for the treatment of vertebral metastasis.Methods:From June 2020 to July 2022, a total of 82 patients with vertebral metastasis underwent percutaneous vertebroplasty and biopsy treated in Linyi Cancer Hospital were enrolled, 39 patients with 57 vertebral bodies were performed by unilateral pedicle approach (unilateral group) and 43 patients with 52 vertebral bodies were performed by bilateral pedicle approaches (bilateral group), used bone cement filling vertebral bodies after biopsy. The clinical efficacy and the positive rate of biopsy were compared between the two groups.Results:Both groups experienced significant pain relief in the Visual Analog Scale (VAS) score and improvement in the Oswestry Disability Index (ODI) score after operation ( P<0.05), but there were no significant differences between the two groups ( P>0.05). The operative time for a single vertebra, volume of bone cement in unilateral group were less than those in the bilateral group:(44.81 ± 13.01) min vs. (31.84 ± 11.87) min, (4.87 ± 0.92) ml vs. (4.18 ± 0.90) ml, there were significant differences ( P<0.05). There were no significant differences in the incidence of bone cement leakage and the positive rate of biopsy between both groups ( P>0.05). Conclusions:Percutaneous vertebroplasty and biopsy by unilateral and bilateral pedicle approaches are significant improvement for symptoms and functions of patients with vertebral metastasis. The clinical efficacy and the positive rate of biopsy are similar. But the former has easier operation procedure, shorter operative time and less volume of bone cement.

Pyrrole [1,2-α] indole is a novel fused heterocyclic skeleton, which is also the basic structural unit and synthetic intermediate of many natural active products and drugs. Pyrrole [1,2-α] indole heterocyclic derivatives have attracted much attention in organic synthesis and medicinal chemistry because of their extensive and marked biological activities. Plant extracts have always been an important source of active compounds. At present, the alkaloids based on the pyrrole [1,2-α] indole heterocyclic structure discovered and isolated from plant extracts include isatisine, isoborreverine, flinderoles, polyavolensin and yuremamine. This paper reviews the research progress on the biological activity of pyrrole [1,2-α] indole heterocyclic derivatives and has found that pyrrole [1,2-α] indole heterocyclic derivatives have a good development prospect in screening active compounds and developing candidate drugs.

Salvia miltiorrhiza Bge(SMB)has long been used in traditional Chinese medicine to treat cardiovascular and cerebrovascular diseases.Growing clinical usage has led to a huge demand for artificial planting of SMB.Thus,continuous cropping of SMB is an important challenge that needs to be addressed.Contin-uous cropping can alter the metabolic profile of plants,resulting in poor growth and low yield.In this study,we tried to image the spatial location and variation of endogenous metabolites in continuously cropped SMB using matrix-assisted laser desorption/ionization mass spectrometry imaging(MALDI-MSI).Spatially resolved expressions of tanshinones,salvianolic acids,polyamines,phenolic acids,amino acids,and oligosaccharides in normal and continuously cropped SMB roots were compared.The ex-pressions of dihydrotanshinone Ⅰ,tanshinone Ⅱ A,dehydromiltirone,miltirone,dehydrotanshinone ⅡA,spermine,salvianolic acid B/E,tetrasaccharide,and pentasaccharide in continuously cropped SMB roots were much lower than those in normal roots.There was little difference in the expressions of caffeic acid and salvianolic acid A in normal and continuously cropped SMB roots.Ferulic acid was more widely distributed in xylem of normal SMB but strongly expressed in xylem,phloem,and cambium of continuously cropped SMB.The spatially resolved metabolite information enhances our understanding of the metabolic signature of continuously cropped SMB and also provides insights into the metabolic ef-fects of continuous cropping in other plants.
