Objective To investigate the angioarchitecture and the efficacy of endovascular embolization of uterine fibroids. Methods Bilateral internal iliac and uterine arteriography were performed to domonstrate the angioarchitecture in uterine fibroids with Seldinger technique. The feeding arteries of uterine fibroids were super-selectively embolized. Results The uterine arteries of 30 patients all originated from the iliac arteries of the ipsilateral side. The feeding arteries of uterine fibroids showed bilateral dominance in 16 cases (53%), unilateral dominance in 11 (37%) and unilateral feeding in only 3(10%). All symptoms disappeared after embolization. The fibroids masses decreased averagely by 40% in size at 3-month with ultrasound follow-up, by 55% at 6 months and by 60% at 12 months with a total clinical efficacy of 100%. Conclusions The key to efficacy and prevention of relapse is to understand the angioarchitecture in order to occlude all the pathological vessels in uterine fibroids.

Objective To explore the clinical significance of plasma fibrinogen(FIB)and plasma D-dimer (D-D)changes involved in lung cancer patients before and after interventional therapy.Methods 23 patients with lung cancer,27 cases of normal control group collected at the same time,to compared the difference of plasma FIB between patients with lung cancer and the normal control group.All enrolled patients were treated with bronchial artery infusion chemotherapy.Plasma FIB and D-D of all patients were meas-ured before the first and the third interventional therapy.Results Plasma FIB value of patients before interventional therapy was sig-nificantly higher than that of the normal control group and the group after interventional therapy.The difference between the group after interventional therapy and the normal control group was no significant;Plasma D-D value of patients before and after interven-tional therapy was significant.Conclusion Changes of plasma FIB and D-D before and after interventional therapy in patients with lung cancer are significantly correlated with the severity of the disease and interventional therapy efficacy,which can be used as a ver-y meaningful indicator of interventional therapy.

Objective To explore the correlation between the change of CT value of osteolytic bone metastasis after the treatment of zoledronic acid and bone metabolism before treatment in breast cancer patients.Methods Twenty breast cancer patients with osteolytic bone metastases were diagnosed by 99m Tc-MDP bone scintigraphy and 99m Tc-MDP SPECT/CT ( contain 16-slice spiral CT) for the first time entered this study.After treatment of zoledronic acid for 3-12 months with the same method, 99m Tc-MDP bone scintigraphy and 99mTc-MDP SPECT/CT were peformed in the 20 breast cancer patients again with the same CT scan parameters(voltages:120kV, tube currents:80mA, pitches:3.75mm).With using regions of interesting (ROI)technique, the T/NT value of osteolytic bone metastases in the first 99m Tc-MDP bone scintigraphy were measured.The CT value of same ROI before and after zoledronic acid therapy were measured (CT1 and CT2), and the change of CT value (△CT,△CT=CT2-CT1) were calculated.The correlation between them were analyzed. SPSS 16.0 was applied for variance and linear correlation analyses.Results (1)A total of 30 lesions of osteolytic bone metastases were detected in the 20 breast cancer patients by the first 99m Tc-MDP bone scintigraphy and 99m Tc-MDP SPECT/CT.The CT value before therapy was significantly higher than that after therapy(425 ±152HU vs 120 ±73HU, t=9.95, P<0.01).(2)The change of CT value after therapy was positively correlated with and the T/NT value of osteolytic bone metastasis(r=0.907, P<0.01).(3)The change of CT value of positive lesions after therapy was significantly higher than that of negative lesions by 99mTc-MDP bone scan(W=15,P=0.001). Conclusion 99m Tc-MDP bone scintigraphy provides an effective method to predict the efficacy of zoledronic acid for breast cancer pa-tients with osteolytic bone metastases.The breast cancer patients with high bone metabolism should be recommended zoledronic acid thera-py, conversely should not be recommended.

Objective To investigate the kinetics of PML-RARα fusion gene in acute promyelocytic leukemia(APL)to monitor minimal residual disease(MRD). Methods In induction therapy,consolidation and maintenance therapy courses, PML-RARα fusion gene was performed by RT-PCR. Results The long-term follow-up of 18 cases achieved complete remission (CR),two cases experienced molecular relapse. One case relapsed at 4 months after CR1 and achieved CR2 after induction therapy. However, molecular and hematology relapsed again at 2 months after CR2 and re-achieved CR3. The other case relapsed at 74 months after CR1 and achieved CR2 after induction treatment, who had survived for 106 months until the end of follow-up. Conclusion RT-PCR assay for detection of PML-RARα should be performed regularly during CR period so as to find molecular relapse eady. Hematological relapse could potentially be averted through treatment modification according to molecular monitoring results of PML-RARα.
