Our previous research demonstrated that the Wenxia Changfu Formula (WCF), as a neoadjuvant therapy, inhibits M2 macrophage infiltration in the tumor microenvironment and prevents lung cancer metastasis. Given tumor-associated macrophages (TAMs) in epithelial-mesenchymal transition (EMT), this study investigated whether WCF impedes lung cancer metastasis by attenuating TAM-induced EMT in non-small cell lung cancer (NSCLC) cells. Utilizing a co-culture model treated with or without WCF, we observed that WCF downregulated cluster of differentiation 163 (CD163) expression in macrophages, reduced CCL18 levels in the conditioned medium, and inhibited the growth, invasion, and EMT of NSCLC cells induced by macrophage co-culture. Manipulation of CCL18 levels and Src overexpression in NSCLC cells revealed that WCF's effects are mediated through CCL18 and Src signaling. In vivo, WCF inhibited recombinant CCL18 (rCCL18)-induced tumor metastasis in nude mice by blocking Src signaling. These findings indicate that WCF inhibits NSCLC metastasis by impeding TAM-induced EMT via antagonistic modulation of CCL18, providing evidence for its potential development and clinical application in NSCLC patients.

Objective:To investigate the status of fear disease progression and hope level in patients with transient ischemia attack and to analyze the relationship between them.Methods:From January 2018 to March 2020,a convenient sampling method was used to select 136 patients with transient ischemia attack. The Chinese version of the Fear of Progression Questionnaire-Short Form(FoP-Q-SF) and Herth Hope Index(HHI) were investigated.Results:The total score of FoP-Q-SF in patients with transient ischemia attack was 32.78±5.34, and the total score of HHI was 34.86±5.12. The total score of FoP-Q-SF and the scores of each dimension were negatively correlated with the total score of HHI and the scores of each dimension ( r values were -0.613--0.376, all P<0.05). Conclusions:Patients with transient ischemia attack have a higher level of fear disease progression, which is related to the level of hope, and can reduce the level of fear disease progression by increasing the level of hope.
