Readmission of children with bronchopulmonary dysplasia in the first 2 years of life: a clinical analysis of 121 cases / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To investigate the clinical features of readmitted children with bronchopulmonary dysplasia (BPD) in the first 2 years of life.</p><p><b>METHODS</b>A retrospective analysis was performed for the clinical data of 242 children with BPD who were readmitted due to recurrent lower respiratory tract infection (LRTI) in the first 2 years of life.</p><p><b>RESULTS</b>Among all the 242 children with BPD, 115(47.5%) had wheezing, and the children aged 1-2 years had a significantly higher incidence rate of wheezing than those aged less than 1 year (P<0.05). Chest imaging was performed for 193 children, among whom 31 (16.1%) had hyperlucent areas. Pulmonary function examination showed that the BPD children had significantly lower TV/kg, TPEF/TE, VPEF/VE, TEF50 and TEF75, and significantly higher respiratory rate than the controls without respiratory disease (P<0.05). Bronchoscopy was performed for 28 children, among whom 21 (75%) had airway dysplasia. All the 242 children used inhaled corticosteroids (ICS) and experienced no treatment-related adverse reactions. Six children were given intravenous infusion of human umbilical cord blood mesenchymal stem cells (hUCB-MSCs) and experienced no infusion-related events or adverse reactions, among whom one child successfully stopped oxygen therapy.</p><p><b>CONCLUSIONS</b>The incidence rate of wheezing increases with the increase in age in children with BPD who are readmitted due to LRTI. Pulmonary function examination shows small airway obstruction, reduced expiratory flow rate in case of low lung capacity, and increased respiratory rate, and most children have airway dysplasia. ICS can be used to inhibit inflammatory response in the acute stage. Infusion of hUCB-MSCs is safe and feasible and may bring some benefits to the recovery from BPD.</p>

Effects and complication treatments of microwave ablation for benign thyroid nodules / 局解手术学杂志

Objective To explore the effects and complication treatments of microwave ablation(MWA) for benign thyroid nodules.Methods The clinical data of 74 patients with benign thyroid nodules treated with MWA in our department from June 2014 to May 2015 were collected and studied retrospectively.Furthermore,the effects and complication treatments were analyzed and calculated.Results A total of 93 nodules were treated with MWA,of which 46 were the main nodules,cystic 47;7 nodules' ablation were not complete,the complete ablation rate was 92.47％.The postoperative reduction of volume in cystic nodules were significantly higher than solid nodules,and the number of solid nodules decreased more rapidly postoperation.The untreated cystic nodules developed a certain degree of growth after 6 months of surgery.After treatment,the TSH of solid nodules were obviously higher,the FT3 and FT4 were much lower than those before treatment and cystic nodules(P ＜ 0.05).A total of 17 cases of complications occurred in the positive symptomatic treatment,all cases were cured within a few days,there was no serious complications.Conclusion Microwave ablation has a high ablation rate in the treatment of thyroid benign nodules,the ablation effects are different between solid and cystic nodules;early and targeted measures can effectively prevent and deal with surgical complication.
