Objective To analyze the clinical value of ultrasound-guided percutaneous Lauromacrogol Injection sclerotherapy in the treatment of simple renal cyst. Methods A total of eighty patients with simple renal cyst, who were divided into 40 groups according to the random number table, were divided into two groups from February 2016 to April 2017. The traditional group used traditional open renal cyst unroofing decompression. Ultrasound guided ultrasound guided percutaneous Lauromacrogol Injection sclerotherapy was performed in the ultrasound guided group. The therapeutic effect, operation time and the rate of successful puncture were compared between two groups of simple renal cysts. It needs to compare the volume of the cyst and the quality of life before and after the intervention. Results Ultrasound guided group simple renal cyst treatment effect was higher than the traditional group (P<0.05). The operation time of the ultrasound guided group was shorter than that of the traditional group, and the success rate of the one shot puncture was higher than that of the traditional group(P<0.05). Before the intervention, the volume and quality of life of the two groups were similar. In the ultrasound guided group, the volume and quality of life in the ultrasound guided group were better than those in the traditional group(P<0.05). Conclusion Ultrasound guided percutaneous Lauromacrogol Injection sclerotherapy is of high clinical value in the treatment of simple renal cysts. The utility model can improve the success rate of one puncture, shorten the operation time, and the exact effect can speed up the regression of symptoms and reduce the volume of the cyst. Therefore, this method can improve the quality of life of patients.

Objective Three-dimension (3D) cell matrix adhesion in vivo is fundamentally important for a wide variety of cellular physiological and pathological phenomena, however, the cell-matrix 3D adhesion is hardly observed in vitro. We present the human foreskin fibroblasts (HFF) formed 3D adhesion complexes on the thoroughly acellular human amniotic matrix (TAHAM). Methods TAHAM were produced by suspending digestion with trypsin. The HFF were seeded on 6 well plate, matrigel and TAHAM individually.The light microscope, scanning electronic microscope, immunohistochemistry and immunofluorescence were used to observe the micro-structures and detect the type Ⅰ , Ⅲ, Ⅳ, Ⅵ collagen, laminin, fibronectin, TGF-β1, TGF-β2, FGF of the TAHAM. Phase contrast microscope was engaged to observe the morphology of HFF. The time-lapse CCD and the trace analysis software were employed to prescribe the cell migration. The 3D adhesion foci were identified by the laser confocal microscope. The strain of the TAHAM was tested by the universal mechanical testing instrument. Results The fibers of the TAHAM were intact, type Ⅰ , Ⅲ,Ⅳ, Ⅵ collagen, laminin, fibronectin were positive, TGF-β1, TGF-β2, FGF were negative. HFF had a bipolar extension to form multilayer cell clusters networks and grew into the matrix. All of the seeded cells survived three weeks under regular culture without transfer. On TAHAM, HFF moved in a straight line with a speed of 12 μm/h. α5 integrin (green), paxillin (red) and fibronectin (blue) co localized to form 3D adhesion complexes (white). Conclusion The main molecular components and biomechanical properties is preserved in TAHAM. HFF forms 3D adhesion complexes on TAHAM. Cell morphology and migration of HFF on TAHAM correspond to that under 3D adhesion behavior.

Objective: To explore the effect of exercise preconditioning (EP) on pathological cardiac hypertrophy and heart failure (HF) in pressure over-loaded experimental rats.
Methods:A total of 60 SD rats at the age of 6 weeks were randomly divided into 3 groups, n=20 in each group. Sham-operation group, Transverse aortic constriction (TAC) group and EP + TAC group. The cardiac function and structure were evaluated by echocardiography, patholgical changes and HF biomarkers were examined for EP effect at 4 and 8 weeks after TAC.
Results:Compared with Sham-operation group, the cardiac function and structure had obvious changes in the other 2 groups. Compared with TAC group, the ejection fraction in EP+ TAC group increased 15%, the heart weight index and left ventricular weight index decrease 15.7%and 20%respectively at 8 weeks after TAC, all P<0.05. Compared with Sham-operation group, the mRNA and protein expressions of ANP and BNP increased in TAC group at 4 and 8 weeks after TAC, increased in EP+TAC group at 8 week after TAC. Compared with TAC group, the mRNA expressions of ANP and BNP in EP+TAC group decreased 47%and 62%at 4 weeks after TAC, decreased 44%and 28.1%at 8 weeks after TAC, all P<0.05;the protein expression of ANP and BNP in EP+TAC group decreased 22.3%and 48%at 4 weeks after TAC, decreased 21.5%and 38.3%at 8 weeks after TAC, all P<0.01.
Conclusion: EP may improve cardiac pathological hypertrophy in pressure over-loaded rats at the early stage, and delay the heart failure process.

Objective To investigate the accuracy of CTVision image-guided stereotactic body radiation therapy (SBRT) for non-small cell lung cancer (NSCLC).Methods 10 lung SBRT patients were imaged with CTVision before and after irradiation for acquiring and analyzing the three-dimensional set-up error data sets in our department from October 2010 to May 2012.Gross tumor volumes (GTVs) were contoured on pre-and post-SBRT CT sets and combined for generating internal gross tumor volumes (IGTVs).Planning target volume (PTV) margin was calculated,and IGTVs and PTVs were compared for off-line verification of accuracy of SBRT.A paired t-test statistical analysis was conducted with the datasets using SPSS 17.0.Results 80 CT image sets were totally obtained.Setup errors was significant difference before and after radiotherapy in the left-right,superior-inferior and anterior-posterior directions,that were (-0.10±1.30) mmand (-0.15±1.31) mm (P=0.720),(0.18±1.32) mm and (0.18±1.43) mm (P =1.000) and (-0.08 ± 1.19) mm and (-0.13 ± 1.18) mm (P =0.750),respectively.IGTVs of ten patients were smaller than corresponding PTVs (13.53 cm3 and 37.84 cm3,P =0.000).Conclusion Accuracy and safety of SBRT could be verified by imaging with CTVision before and after delivery for non-small cell lung cancer.

Objective To investigate the clinical significance of the 3D-CTA (three-dimensional computed tomography angiography)assisted design of finger reconstruction the second toe.Methods Between June 2010 and January 2013,five patients with finger defect received 3D-CTA assisted finger reconstruction surgeries using the second toe.Preoperative ipsilateral foot and hand 3D-CTAs were conducted and the 3D digital models were analyzed.The accurate positions and adjacent relations of vessels in both donor and recipient site were precisely marked and then the calibers of the vessels were measured.Four cases received thumb reconstructions and 1 case received little finger reconstruction.All of these surgeries were second-stage.According to Gu Yudong's classification of finger defect:second degree 2 cases,third degree 2 cases,five degree 1 case(little finger).Results With the help of 3D-CTA,five patients in this group had no vascular crisis,and all fingers survived successfully.With 4-12 months' follow-up,the algesthesia and thalposis of the reconstructed fingers gained good recoveries.The two-point discrimination was 5-10 mm.Tthe range of flexion of interphalangeal joint was 10 °-30 °.The range of flexion of the metacarpophalangeal joints was 35 °-80 °.And all patients restored walking and bearing functions with 3 months after surgeries.Conclusion The 3D-CTA reconstruction based digital model of ipsilateral foot and hand can objectively reflect the real situation of the vessels in both donor sites and recipient sites (exist of variations,routes and the calibers of the vessels),thus improve the success rate of surgery.

Objective To compare the clinical target volume (CTV) expanding margins in the mid-and upper-thoracic esophageal carcinoma during radiotherapy measured with and without online image guidance technique by CT on rail.Methods 100 patients with mid-and upper-thoracic esophageal carcinoma undergoing intensity modulated radiotherapy received CT scanning.Image registration was conducted between the scanning results and the planned CT images,thus set-up error data were acquired and got on-line correction.Fifty patients were randomly selected to undergo additional post-treatment CT scanningso as to analyze the revised residuals,displacement during treatment,and infra-fraction GTV shifts.Results Compared to the radiotherapy without CT-based image guidance,the CTV expanding margins obtained with CT-based image guidance was reduced significantly from 9.1,8.8 and 6.1 mm to 4.1,4.5 and 4.3 mm in the left-right,head-feet,and belly-back directions respectively.Conclusions The on-line image-guided technology significantly improves the accuracy of target and reduces the CTV expanding margins.
