ABSTRACT
@#Objective To systematically evaluate the safety and efficacy of percutaneous closure of atrial septal defect (ASD) guided by echocardiography alone versus fluoroscopy. Methods The databases of PubMed, The Cochrane Library, EMbase, VIP, Wanfang Data and CNKI from January 2000 to October 2021 were searched by computer for relevant research literature. Two reviewers independently screened the literature, extracted the data and evaluated the quality according to the inclusion and exclusion criteria. Meta-analysis was performed using RevMan 5.4 software. Results A total of 19 cohort studies and 1 randomized controlled study were collected, including 2 825 patients. The Newcastle-Ottawa Scale score for cohort studies was≥7 points. Meta-analysis showed that there was no statistical difference in the operative success rate (RR=1.01, 95%CI 1.00 to 1.02, P=0.17), incidence of occluder displacement/shedding (RR=0.77, 95%CI 0.26 to 2.27, P=0.63), incidence of arrhythmia (RR=0.50, 95%CI 0.21 to 1.14, P=0.10), incidence of pericardial effusion (RR=0.98, 95%CI 0.32 to 2.98, P=0.97), operative time (MD=–0.23, 95%CI –7.56 to 7.10, P=0.95) or cost (SMD=–0.39, 95%CI –1.09 to 0.30, P=0.27) between the two groups. The echocardiography group reduced the incidence of total postoperative complications (RR=0.42, 95%CI 0.30 to 0.60, P<0.001) and residual shunt (RR=0.70, 95%CI 0.50 to 0.98, P=0.04), and shortened length of hospital stay (MD=–0.43, 95%CI –0.77 to 0.09, P=0.01). Conclusion Compared with traditional fluoroscopy-guided percutaneous closure of ASD, echocardiography guidance alone is equivalent in terms of operative success rate, major postoperative complications, operative time and total cost, but it reduces the incidence of total postoperative complications and residual shunt, and has a shorter length of hospital stay.

ABSTRACT
Objective This study reconstructed 4D-CBCT for fully automatic compensated sliding motion by incorporating the bilateral filtering into the Deformable Vector Field (DVF). Methods First, a motion compensated simultaneous algebraic reconstruction technique (Modified Simultaneous Algebra Reconstruction Technique, mSART) was used to generate a high quality reference phase by using all phase projection stogether with the initial 4D-DVFs, which were generated via Demons registration between 0% phase and each other phaseimage. The 4D-DVF was optimized by matching the forward projection of the deformed 0% phase with the measured projection of the target phase. The loss function’s DVF smoothing constrain term contained bilateral filtering kernel that contained: 1) an spatial domain Guassian kernel; 2) animage intensity domain Guassian kernel; and 3) a DVF domain Guassian kernel. By choosing suitable kernel variances, the sliding motion can be extracted. A non-linear conjugate gradient optimizer wasused. We validated the algorithm on a Non-Uniform Rotational B- spline based Cardiac-Torso (NCAT) phantom. Quantification was evaluated by: 1) the Root-Mean-Square-Error (RMSE) together with the Maximum-Error (MaxE); 2) the Dice coefficient of the extracted lung contour from the final reconstructed images and 3) the relative reconstruction error (RE) to evaluate the algorithm's performance. Results The motion trajectory's RMSE/MaxEare 0.796/1.02 mm for bilateral filtering reconstruction; and 2.704/4.08 mm for original reconstruction. Image content such a stherib position, the hearted gedefinition, the fibrous structures all had been better corrected with bilateral filtering. Conclusion We developed a bilateral filtering based fully automatic sliding motion compensated 4D-CBCT scheme. Digital phantom study confirmed the improved motion estimation and image reconstruction ability. It can be used as a 4D-CBCT image guidance tool for lung SBRTtreatment.

ABSTRACT
Objective To discuss the clinical value of transesophageal echocardiography used in extracorporeal circulationcardiac valve replacement. Methods 89 patients received extracorporeal circulation cardiac valve replacement in our hospital from January 2012 to December 2014 were included in the study. Transesophageal echocardiography were performed preoperatively, intraoperation and postoperatively and the findings were compared to the result of preoperation transthoracic echocardiography exam. The measurement of aortic annulus diameter and detection rates of calcification obtained by transthoracic and transesophaged echocardiography were compared. Changes in heart function parameters before and after operation were compared. The alternations in surgery plan made after pre-operative transesophageal echocardiography exam and any relevant treatment or procedure performed according to intra-operation transesophageal echo findings were recorded. All the patients were followed up for 6 months - 40 months. Results Before extracorporeal circulation cardiac valve replacement, the aortic annulus diameter measured and detection rates of calcification by transthoracic echocardiography were smaller and lower than actual surgical pathology results ( P 0. 05 ) . Conclusions For patients receiving extracorporeal circulation cardiac valve replacement, transesophagus echocardiography examination is helpful to guide the selection of valve stent and operation methods.

ABSTRACT
BACKGROUND:Naringin can increase bonemorphogeneticprotein 2 gene expression and promote the proliferation and differentiation of multipotential stem cel line. In vitro cel experiment indicates that naringin can suppress osteoclast formation and anti-osteoporosis activity. OBJECTIVE:To prepare a mouse calvarial bone culture model containing naringin and to observe the effect of naringin with different concentrations on the formation and function of osteoclasts. METHODS:Calvarial bone was dissected out aseptical y from the 4-day-old Sprague Dawley mice, and cultured in the culture medium containing 0, 1, 10 and 100 mg/L naringin. The effects of naringin on the number of tartrate-resistant acid phosphatase-positive osteoclast marker enzyme in calvarial bone and the concentration of calcium in the culture medium were detected after cultured for 1, 3, 7 and 10 days. RESULTS AND CONCLUSION:After cultured for 1 day, the number of tartrate-resistant acid phosphatase-positive cel s in calvarial bones and the calcium concentration in the culture medium had no difference between the groups. After cultured for 3 and 7 days, the number of tartrate-resistant acid phosphatase-positive cel s was decreased and the calcium concentration was increased with the increasing concentration of naringin. At 10 days after culturing, this trend was most obvious. It showed that naringin could affect the number and function of tartrate-resistant acid phosphatase-positive cel s in calvarial bones, and this effect showed a significant time-and dose-depend manner. The results show that naringin can not only promote the proliferation of osteroclasts, but also reduce the differentiation of osteoclasts or accelerate the apoptosis.
