Objective To evaluate the safety and efficacy of intravascular lithotripsy(IVL)in the treatment of coronary artery calcification lesions.Methods A total of 53 patients who underwent endovascular imaging guided treatment of coronary artery calcified lesions with either IVL or cutting balloon(CB)at the Affiliated Hospital of Jining Medical College from January 2023 to July 2023 were retrospectively analysed(IVL:n=18,CB:n=35)were retrospectively analysed to compare the technique,clinical success rate,major adverse cardiovascular events(MACE)and readmission for cardiovascular events in patients followed during hospitalisation and 1 month after the procedure.Results Clinical success rates were identical in the IVL and CB groups(100.0％vs.100.0％,P＞0.999),the minimum lumen area of lesions was similar in the VL and CB groups[(1.7±0.4)mm2 vs.(1.7±0.5 mm2),P=0.628].And there was a statistically significant difference in the overall mean lesion length between the IVL and CB groups[(28.4±9.6)mm vs.(20.9±8.6)mm,P=0.008].During the procedure,there were no complications such as aneurysm,thrombus,or emergency vessel closure.There was a statistically significant difference in the overall mean value of residual stenosis between the IVL and CB groups[(1.7±1.7)％vs.(6.9±2.0)％,P=0.049].There were no MACE in either group during hospitalisation or at the one-month follow-up(0 vs.0,P＞0.999),and 3 patients in the CB group were readmitted for angina pectoris(0 vs.8.6％,P=0.543),with no significant difference in readmission rates between the two groups.Conclusions The technique of intravascular lithotripsy is safe and effective in the treatment of coronary artery calcification lesions.

Objective:TThe aim of this study was to observe the changes of the volume and distribution of body fluid after abdominal surgery,and further to explore its characteristics and influence factors.Methods:Sixtyone patients were included between March and June in 2016.The volume of intracellular water (ICW),extracellular water (ECW) and total body water (TBW) was estimated by InbodyS 10 on preoperative day 1 (PreD 1) and postoperative day (POD) 1,3,5 and 7.Furthermore,the patients were grouped according to the age,sex,type of operation,operation time and the daily liquid input,and the influence factors of postoperative fluid volume were analyzed in each subgroup.Results:Comparing to that of PreD1,the ICW,ECW,and TBW,mainly ECW,were increased significantly on POD1 (P＜ 0.05),and the level of postoperative fluid volume was decreased to that of PreD1 between POD3 and POD7.It showed that there was difference in the net increasing of body fluid on POD1 between different type of the patients.Obviously,the net increasing of fluid volume in woman on POD 1 was more than that in man.The net increasing of fluid volume on POD1 was correlated with the operation time and net liquid input.Conclusion:The fluid retention was found in the early stage of postoperative patients,and mainly exists in ECW.The main influence factors resulting postoperative fluid retention were prolonged operation time and increased net fluid input.

<p><b>OBJECTIVE</b>To investigate the clinical features and outcomes of neuroblastoma (NB) children aged above 5 years, and to provide a theoretical basis for improving prognosis.</p><p><b>METHODS</b>A retrospective analysis was performed for the clinical data of 54 previously untreated NB children, and their clinical features and outcome were analyzed. The Kaplan-Meier method was used for survival analysis.</p><p><b>RESULTS</b>Among the 54 children, there were 36 boys and 18 girls, and all of them had stage 3 or 4 NB. Of all the children, 41 (41/54, 76%) had retroperitoneal space-occupying lesions, 10 (10/54, 18%) had mediastinal space-occupying lesions, 2 (2/54, 4%) had intraspinal space-occupying lesions, and 1 (1/54, 2%) had pelvic space-occupying lesions. At the end of the follow-up, 30 children (30/54, 56%) survived, among whom 23 (77%) achieved disease-free survival (9 achieved complete remission after chemotherapy for recurrence), 6 (20%) achieved partial remission of tumor (all of them received chemotherapy again due to recurrence), and 1 (3%) experienced progression (with progression after chemotherapy again due to recurrence); 24 children (44%) died, among whom 22 died after chemotherapy again due to recurrence and 2 died of multiple organ failure during the first treatment. According to the Kaplan-Meier survival analysis, the mean survival time was 53.8 months, and the children with stage 3 NB had a significantly higher overall survival rate than those with stage 4 NB (80% vs 53%; p<0.01). The children with recurrence had a significantly lower mean survival time than those without recurrence (51.68 months vs 62.57 months; p<0.01).</p><p><b>CONCLUSIONS</b>Older children often have late-stage NB, but standard treatment can improve their outcomes.</p>
