Objective To observe the curative effect of refractory ascites with ascitic ultrafiltration and reinfusion into abdominal cavity.Methods Thirty-seven patients diganosed as refractory ascites were given ultrafiltration and reinfusion into abdominal cavity.The following parameters were detected respectively:24h urine volume,abdomen circumference,heart rate,blood pressure,serum electrolytes,serum albumin,total serum bilirubin.Results After treatment,the 24h urine volume increased and abdomen circumference decreasd significantly (P ＜ 0.01 ).There was no significant difference in heart rate,blood pressure,serum electrolytes,serum albumin and total serum bilirubin before and after treatment (P ＞0.05).Conclusion Ascitic ultrafiltration and reinfusion into abdominal cavity has some effects on refractory ascites.

Objective:To investigate the value of flexible bronchoscopy and neck ultrasound in percutaneous dilatational tracheotomy (PDT) in infants.Methods:The clinical data of 24 patients, who underwent flexible bronchoscopy and neck ultrasound assisted PDT in the Center for Respiratory Intervention, Children′s Hospital Affiliated to Shandong University from December 2018 to May 2021, were retrospectively analyzed.Of the 24 cases, 12 were male and 12 female.The male to female ratio was 1∶1.The age range was 21 days to 2 years (median: 5 months). The median mass was 5.8 kg.During the PDT, neck ultrasound was used to assess the thyroid position and vascular shape of vessels.After determining the puncture approach and marking the tracheostomy site, the PDT was performed under the guidance of flexible bronchoscopy.Results:Before surgery, 19 children (79.2%) had received continuous endotracheal intubation mechanical ventilation support, 2 children (8.3%) were treated by intermittent endotracheal intubation mechanical ventilation support therapy, and 3 children (12.5%) were supported by the non-invasive ventilator.There were 9 cases (37.5%) of congenital upper respiratory tract malformation, 8 cases (33.3%) of bilateral vocal cord paralysis, 3 cases (12.5%) of upper respiratory tract neoplastic diseases, 2 cases (8.3%) of surgical evacuation difficulties, and 2 cases (8.3%) of neuromuscular disease.All 24 patients successfully completed the operation within 30 min, with bleeding volume less than 5 mL and no intraoperative complications.Conclusions:Flexible bronchoscopy and neck ultrasound can assist in the successful PDT in infants, significantly reduce the difficulty and improve the safety of PDT.

Objective:To analyze the association between elevated blood pressure (BP) and carotid intima-media thickness (cIMT) in children according to four BP references.Methods:Study population came from"Huantai Childhood Cardiovascular Health Cohort Study"in Huantai County, Zibo City, Shandong Province. A convenient cluster sampling method was used to conduct a cross-sectional survey on 1 515 children from November 2017 to January 2018 in a primary school. A total of 1 431 children aged 6-11 years old with complete data were included in this study. Data on demographic characteristics, BP and cIMT were collected through questionnaire survey, physical examination and ultrasound examination. High cIMT was defined as the level of cIMT ≥ age-and sex-specific 90 th percentile of this study population. Based on the Chinese Guideline reference, the Health Industry reference, the International reference and the U.S. reference, all participants were divided into three subgroups: the normal BP, high normal BP and, elevated BP. The multivariate logistic regression models were used to examine the association between BP status and high cIMT in children. Results:The age of children was (8.9±1.5) years, and boys accounted for 53.4% ( n=682). The multivariate logistic regression models showed that after adjusting for relevant confounding factors, the risk of high cIMT in elevated BP group was increased compared with the normal BP group according to the four references (all P values<0.05) Conclusion:Elevated BP according to the four BP references is associated with high cIMT in children.
