ABSTRACT
OBJECTIVE@#To evaluate the effect of Chinese medicine (CM) treatment on survival time and quality of life (QOL) in patients with small cell lung cancer (SCLC).@*METHODS@#This was an exploratory and prospective clinical observation. Patients diagnosed with SCLC receiving CM treatment were included and followed up every 3 months. The primary outcome was overall survival (OS), and the secondary outcomes were progression-free survival (PFS) and QOL.@*RESULTS@#A total of 136 patients including 65 limited-stage SCLC (LS-SCLC) patients and 71 extensive-stage SCLC (ES-SCLC) patients were analyzed. The median OS of ES-SCLC patients was 17.27 months, and the median OS of LS-SCLC was 40.07 months. The survival time was 16.27 months for SCLC patients with brain metastasis, 9.83 months for liver metastasis, 13.43 months for bone metastasis, and 18.13 months for lung metastasis. Advanced age, pleural fluid, liver and brain metastasis were risk factors, while longer CM treatment duration was a protective factor. QOL assessment indicated that after 6 months of CM treatment, scores increased in function domains and decreased in symptom domains.@*CONCLUSION@#CM treatment might help prolong OS of SCLC patients. Moreover, CM treatment brought the trend of symptom amelioration and QOL improvement. These results provide preliminary evidence for applying CM in SCLC multi-disciplinary treatment.
ABSTRACT
The active ingredients of Ficus hirta and Hypericum perforatum were collected from Traditional Chinese Medicine Database and Analysis Platform(TCMSP) and related papers. The potential targets of these two medicinal herbs were searched from HERB database, and those associated with microvascular angina were screened out from GeneCards, Online Mendelian Inheritance in Man(OMIM), Therapeutic Target Database(TTD), and HERB. Cytoscape was used to construct a protein-protein interaction(PPI) network of the common targets shared by the two herbs and microvascular angina based on the data of String platform. Metascape was employed to identify the involved biological processes and pathways enriched with the common targets. Cytoscape was used to draw the "active ingredient-target-pathway" network. AutoDock Vina was used to dock the core ingredients with the key targets. A total of 19 potential active ingredients and 71 potential targets were identified to be associated with microvascular angina. Bioinformatics analysis showed that phosphatidylinositol-3-kinase/protein kinase B(PI3 K-AKT), interleukin-17(IL17), hypoxia-inducible factor 1(HIF-1) and other signaling pathways were related to the treatment of microvascular angina by F. hirta and H. perforatum. Molecular docking results showed that β-sitosterol, luteolin and other ingredients had strong affinity with multiple targets including mitogen-associated protein kinase 1(MAPK1), epidermal growth factor receptor(EGFR) and so on. These findings indicated that F. hirta and H. perforatum may regulate PI3 K-AKT, IL17, HIF-1 and other signaling pathways by acting on multiple targets to alleviate oxidative stress, inhibit inflammatory response, regulate angiogenesis, and improve vascular endothelium and other functions. This study provides reference for in vitro and in vivo studies of the treatment of microvascular angina.
