OBJECTIVETo investigate the dynamic features of angiogenesis in residual tumors after high intensity focused ultrasound (HIFU),and to determine the temporal effect and mechanism of hypoxia inducible factor-2 alpha (HIF-2a) in the angiogenic process of residual tumors.
METHODSXenograft tumors of HepG2 cells were generated by subcutaneously inoculating athymic BALB/c nu/nu mice with the hepatoma cells.About 30 days after inoculation,all mice (except in the control group) were treated by HIFU and assigned randomly to the following 7 groups according to various time intervals post-treatment:1st,3rd,5th day and 1st,2nd,3rd,4th week when the residual tumor tissues were obtained from the experimental groups.Protein levels of HIF-2a and vascular growth factor A (VEGF-A) were quantified by immunohistochemistry and western blotting,and mRNA levels were measured by (real-time quantitative) qPCR. Microvascular density (MVD) was calculated by counting the CD31-positive vascular endothelial cells identified by means of an immunohistochemical staining method.
RESULTSCompared with results from the control group,the protein and mRNA levels of HIF-2a expression reached the highest level in the experimental mice at the 2nd week (P=0.000 and P < 0.01 respectively),and were decreased thereafter(3rd week and 4th week, P=0.000 and P < 0.05).VEGF-A expression in the residual tumor tissues group that received HIFU was significantly decreased,compared with the control group,at all time points uPto 1 week (all P=0.000 and P < 0.01),but the levels increased compared to controls in the 2nd through 4th week (all P=0.000, P < 0.05). Similar results were obtained for MVD.
CONCLUSIONHIFU treatment can inhibit angiogenesis in residual hepatoma tissues in the short-term (1 to 2 weeks post-treatment) in mice with hepatocellular carcinoma,but can promote angiogenesis overtime (2 to 4 weeks post-treatment); the angiogenic process may involve the HIF-2α/VEGFA pathway.

OBJECTIVETo study the changes in hypoxia-inducible factor (HIF1α, HIF2α) in the residual tumor cells in nude mice bearing hepatocellular carcinoma (HCC) following treatment with high-intensity focused ultrasound (HIFU).
METHODSThirty nude mice bearing human HCC received treatment with HIFU. At 1, 3, and 5 days and 1 and 2 weeks after the treatment, the mice were examined for pathological changes of the residual tumor with HE staining; SP immunohistochemistry, Western blotting and real-time quantitative PCR were used to detect the protein and mRNA expressions of HIF1α and HIF2α in the tumor.
RESULTSHE staining revealed the presence of residual tumor cells and large necrotic areas after the treatment. Immunohistochemistry showed a gradual increment of HIF1α protein and mRNA expressions after the treatment, reaching the peak level at 3 days (P<0.05) followed by progressive reduction at 5 days and 1 and 2 weeks. HIF2α expressions at either the protein or mRNA levels exhibited no significant changes within 3 days after the treatment (P>0.05) but increased significantly at 5 days and 1 and 2 weeks (P<0.05).
CONCLUSIONThe changes of HIF1α and HIF2α in the residual tumor after HIFU treatment in nude mice bearing HCC can be associated with tumor cell apoptosis and angiogenesis after the treatment.

Objective To observe the feasibility in neurosurgical brain tumor resection using ultrasound fusion navigation technology . Methods Thirty patients undergoing brain tumor rescetion accepted fusion ultrasound ( US ) navigation with magnetic renounce/computed tomography ( MR/CT ) technique and cognitive fusion" by neurosurgeon based on the tumor′s localization of magnetic renounce imaging (MRI) separately to definite the position and size of the craniotomy window flaps . After removal cranial bone ,conventional B-mode ultrasound scanning was used to detect lesion firstly . Then ,fusion US/MR navigation was applied again after automatically registration;the images of tumors from B-mode ultrasound and contrast-enhanced ultrasound separately were compared to those from coplanar reconstructive MR/CT in a real time . Results Fusion US/MR navigation was useful to define the position and size of the craniotomy window flaps ,and tumors in all patients were fully exposed to the microscope field of view . In all of 30 cases ,26 cases of fusion imaging of volume navigation technology were successfully registrated . The tumors in 3 cases of glioma ( WHO Ⅰ - Ⅱ grade) and 1 patient with pathologically verified inflammatory couldn′t be localized by conventional B-mode ultrasound but could be accurately localized after fusion ( US/MR) imaging navigation . Compared to contrast-enhanced MR ,high-grade glioma with contrast-enhanced ultrasound (CEUS) showed enhancement in arterial phase and clear tumor boundary rapidly . The enhanced modality with CEUS and MR was functioned equal . Low-grade glioma with CEUS showed scattered point or linear enhancement in arterial phase and the tumor′s margin was blurred . The preoperative T1-weighted enhanced MRI demonstrated no enhancement in the low-grade glioma . Conclusions Fusion ultrasound navigation can be used to definite size of bone flap before craniotomy . It is more suitable for fusion with preoperative T 2 Flair phase to localize low grade glioma . High-grade glioma is suitable to preoperative T 1 weighted enhanced phase for discerning margin of tumor .
