摘　　要：Objective:To study the effect and mechanism of Huayu Wan(化瘀丸,HYW)in combination of chemotherapy of tumor treatment.Methods:HYW serum was added in Lewis cells to assess its impact on fluorescent doxorubicin delivery in vitro.Then,Lewis tumor cells was implanted in C57BL/6 mice via xenograft transplantation.Tumor growth was measured and signal intensity corresponding to blood flow was assessed by laser doppler perfusion imaging(LDPI).Finally,the effect of HYW on the effificacy of doxorubicin was studied.Results:HYW can improve the transfer of fluorescent doxorubicin into cells.The blood flow signal in the tumor tissues of the HYW group was higher than that of the control group(P<0.01).Furthermore,HYW improved drug delivery of doxorubicin to tumor tissues,and this activity was associated with HYW-induced microvascular proliferation(P<0.01).Conclusions:HYW can promote microangiogenesis and increase blood supply in tumor tissues,which in turn may increase the risk of metastasis.At the same time,HYW increases drug delivery and improves the effificacy of chemotherapy drugs through vascular proliferation.Therefore,rational judgment must be exercised when considering applying HYW to an antitumor regimen.
