Objective:To explore the imaging effect and treatment effect of the ultrasonic microbubble modified by transcriptional activator protein(TATp)and stromal cell-derived factor-1(SDF-1)carrying docetaxel lipid in metastatic lymph node lymph node of tongue cancer.Methods:A control study was made with the VX2 cervical lymph node metastasis in rabbits model
SCC-15 cell and the ultrasonic microbubble modified by TATp and SDF-1 carrying docetaxel.The rabbit model was divided into A
B
C
D groups
respectively dealing with blank microbubbles(A)
targeted microbubbles(B)
drug(C)and blank(D).The cells were divided into:A
B
C
D
E
F groups
respectively dealing with blank(A)
drug group(B)and microbubbles(C)
targeted microbubbles(D)
targeted microbubbles + ultrasound(E)and ultrasound(F).The results were tested by measuring lymph node’s volume
immunohistochemistry
and apoptosis.Results:The ultrasonography revealed metastatic cervical lymph nodes.The tumor inhibitory rates in each group were 5.3%
25.4%
