Journal of Interventional Radiology 2015;(10):873-875
Objective To discuss the clinical application of preoperative transcatheter arterial chemoembolization (TACE) in treating squamous cell carcinoma of tongue. Methods A total of 26 patients with pathologically proved squamous cell carcinoma of tongue were enrolled in this study. Using Seldinger technique, lingual artery angiography and TACE were carried out in all patients. Radical resection of tongue cancer was performed in 2-3 weeks after TACE. Results Super-selective catheterization and TACE was successfully accomplished in all patients. After TACE the tumor size was significantly decreased in all patients. During the operation, clear lesion's border was observed, and the amount of blood loss was less than usual. Conclusion For the treatment of squamous cell carcinoma of tongue, preoperative superselective TACE is safe and effective;it can increase the opportunity of surgical resection, reduce the surgical damage, and improve the quality of life as well as the survival rate.

Acta Universitatis Medicinalis Anhui 2014;(10):1514-1516,1517
Seven patients with nasopharyngeal carcinoma treated with ART were recruited . All patients were treated with SIB-IMRT regimen( named IMRT) . All patients had a second computed tomography scan after 10 fractions and a new plan based on this was initiated from fraction 11 ( ART1 ) . And a third CT scan after 21 fractions and a new plan based on this was initiated from fraction 22(ART2). When the treatment was finished,a fourth CT scan was made. Results revealed that the volumes of primary tumors and parotid glands regressed significantly after the teat-ment. The position of the parotid glands shifted medially an average of 4.5(1.6~9.2)mm during the plans. ART1 reduced mean dose to left parotid by 0. 42 Gy(1. 68%)(P=0.019) and right parotid by 0. 79 Gy (3.04%) (P=0. 013) over the IMRT alone. ART2 further reduced the mean left parotid dose by 0. 86 Gy or 3.5% ( P =0.001 ) and right parotid by 1 . 04 Gy or 4 . 13% ( P=0.035 ) .

ObjectiveTo evaluate the usefulness of an ultrasonography-based method to examine quadriceps femoris contracting. MethodsThe thickness of bilateral rectus femoris (RF) and vastus intermedius (VI) and the cross-sectional area (CSA) of RF was measured in 10 healthy subjects (n=20) in a relaxed position and 3 isometric contraction states using ultrasonography by two examiners. The date was compared with paired t test. Half of these subjects (n=10) were also measured with MRI at rest. The date was also compared with paired t test. ResultsThere was no significant difference between MRI and static compound ultrasonography, nor between two examiners. There was a significant difference (P<0.05) in thickness of RF and VI between relaxed and isometric contraction conditions. There was no significant difference among isometric contraction conditions. There was no significant difference among measurements of RF-CSA. Conclusionultrasonography shows good validity and reliability in measuring quadriceps shape.

Objective To identify the suitable echocardiographic predictor,the standard 2-demensional echocardiography and speckle tracking imaging (STI) techniques were applied for the late referred children with transposition of great arteries with intact ventricular septum (TGA-IVS) after neonatal period.Methods 22 children with TGA-IVS after neonatal period were enrolled.According to the intraoperative left ventricular (LV)/right ventricular systolic pressure ratio,they received pulmonary artery banding (PAB group,n =10) or arterial switch operation (ASO group,n =12).15 body surface area matched healthy children were served as control group,Echocardiography was performed before the operation.The dynamic images in basal and apical short axis view were collected respectively.Meanwhile,using the STI technique,the rotation curves at apex and base was analyzed.Results All the patients discharged eventually.A right to left bulging of the ventricular septum was observed in all the patients by the 2D short-axis view.There were no differences in wall thickness and ejection fraction between control,PAB and ASO group.Compared with the control group,the end diastolic diameter,end diastolic volume and indexed LV mass in PAB and ASO group were significantly reduced,however,no difference in the end diastolic diameter and volume and LV mass was observed between the PAB and ASO group.The hypoplasia of LV in PAB and ASO group was associated with an extended time to peak basal rotation and reduced basal rotation and global torsion.Furthermore,the shorter time to peak apical rotation and reduced apical rotation and global torsion were only observed in PAB group.Conclusions The standard echocardiography could be useful for the initial evaluation for regressed LV of the children with TGA-IVS.However,STI allows a much more precious approach to the assessment of LV regressing after neonatal period.The apical rotation and global torsion might be the better predictor to identify the borderline or regressed LV for the surgical management for the children with TGA-IVS.

ObjectiveTo investigate the expression and activity of Rho-associated kinase 1 (ROCK1) in renal tissues of uninephrectomized diabetic rats,and to explore the possible mechanism of renal protection of spironolactone.Methods The model rats were established by a single intraperitoneal injection of streptozotocin(STZ) after uninephrectomy and randomly divided into sham operation group(N),uninephrectomized control group?,uninephrectomized diabetic group (D),and spironolactone treated group (S).Four and 8 weeks later,biochemical indexes and renal morphology were detected.Expressions of ROCK1 and connect tissue growth factor (CTGF) were examined by immunohistochemistry and real-time PCR.Protein expression of p-MYPT1 was examined by Westem blotting.Results After 4 and 8 weeks,compared with group N and C,blood glucose,systolic blood pressure,24-h urinary protein,kidney weight/body weight (KWI) were significantly increased (P<0.01),and extracellular matrix proliferation and basement membrane thickening were found in group D.After 8 weeks in group D,Alb significantly decreased and Scr significantly increased (P<0.05).In group D,protein and mRNA expression of ROCK1 and CTGF increased significantly and protein expression of p-MYPT1 increased significantly as well with time.Treatment with spironolactone could partially reverse those changes. ConclusionsExpression and activity of ROCK1increase in renal tissues of uninephrectomized diabetic rats and are positively correlated with the expression of CTGF.Spironolactone can protect the kidney of diabetic rats in early stage probably through decreasing the expression of ROCK1,CTGF and inhibiting the activation of ROCK1.
