Objective:To investigate the prognosis and risk factors for children diagnosed with all types of subaortic stenosis(SAS) who developed recurrent left ventricular outflow tract obstruction after surgical treatment.Methods:The study retrospectively included patients aged 0-18 years old who underwent open heart SAS surgery at Fuwai Hospital from 2016-2019. Children with hypertrophic obstructive cardiomyopathy were excluded. Detailed operative notes, medical records and ultrasound information, and follow-ups were extracted. Recurrent SAS was defined as left ventricular outflow tract gradient 30 mmHg(1 mmHg=0.133 kPa) 1 month after SAS surgical treatment.Results:A total of 137 children were included in this study. The medium age of children at the time of SAS surgery was 4.6 years old(3 months-17.8 years old). After a median follow-up of 4.36 years(3.2-5.7 years), a total of 30 patients developed recurrent LVOTO, with a recurrence rate of 21.9%, and 7(5.1%) underwent a second surgery. Compared to the non-recurrent group, children in the recurrent group were younger at the time of surgery( P=0.0443), had a smaller body surface area( P=0.0485), and a longer length of stay( P=0.0380). In Cox analysis, when only considering preoperative variables, the independent risk factor for LVOTO recurrence were a peak left ventricular outflow tract gradient higher than 50 mmHg( HR=5.25, P=0.001), a BSA less than 0.9( HR=2.5, P=0.023), and a length of SAS 5 mm( HR=2.29, P=0.050). When both preoperative and intraoperative variables were considered, preoperative peak left ventricular outflow tract gradient 50 mmHg( HR=4.91, P=0.002) and peeling from the aortic valve( HR=3.23, P=0.010) were independent risk factors for postoperative recurrence. Conclusion:Recurrent LVOTO after SAS surgical repair is common, and regular postoperative follow-up is crucial to evaluate whether a secondary intervention is required. Regular postoperative follow-up is needed for children at high risk.

Objective    To summarize the surgical experience of infants with transposition of the great arteries (TGA) and intramural coronary artery (IMCA) in our center, and analyze the early and mid-term outcomes. Methods    We retrospectively analyzed the clinical data of 384 infants with TGA undergoing arterial switch operation (ASO) from June 2010 to December 2018 at Fuwai Hospital. According to operative records, 21 (5.5%) infants had IMCA, among whom 20 were males, with a median age of 33 (9-319) d. Coronary transfer using double coronary buttons with unroofed intramural course was performed in all 21 infants. Results    There was no statistical difference in the early mortality after ASO between infants with IMCA and infants with normal coronary anatomy (9.5% vs. 3.0%, P=0.15). In the IMCA group, 2 dead patients presented inadequate coronary artery perfusion after first aortic unclamping. In addition, 1 patient underwent extracorporeal membrane pulmonary support for myocardial dysfunction. The follow-up was available for all 19 survivors, with an average follow-up time of 29.0-120.0 (74.8±27.3) months. During the follow-up, all patients had no obvious symptoms, death, reoperation, or coronary complications. One patient developed moderate pulmonary valve regurgitation and another patient developed distal stenosis of the right pulmonary artery. Conclusion    For infants with TGA and IMCA, coronary transfer using double coronary buttons with unroofed intramural course is a safe and reliable technique, with satisfactory early and mid-term outcomes.

Objective:To explore the application effect of chain pain management model in perioperative nursing of children with traumatic fractures.Methods:Using the convenient sampling method, a total of 174 children with traumatic fractures and 174 caregivers who were treated in Henan Children's Hospital from May 2020 to May 2021 and underwent surgical treatment were selected as the research subjects. Among them, 85 children and 85 caregivers from May to November 2020 were used as the control group, and they were given the conventional pain management model for intervention. A total of 89 children and 89 caregivers from December 2020 to May 2021 were selected as the experimental group, and they were given chain pain management model for intervention. The perioperative pain, psychological stress status and nursing satisfaction of caregivers were compared between the two groups.Results:At 24 hours after admission and 24 hours after operation, score of FLACC Pain Assessment Scale of the experimental group was lower than that of the control group, and the difference was statistically significant ( P<0.05) . At discharge, the Short-term Response Scale of Stress Disorder in the experimental group was lower than that in the control group, and the satisfaction score of caregivers in the experimental group was higher than that in the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The application of chain pain management model in perioperative nursing of children with traumatic fractures can reduce perioperative pain, improve the psychological stress state of children and improve satisfaction of caregivers with nursing work, which has certain clinical application value.

Objective: To investigate the clinical efficacy and safety profile of hyaluronic acid dermal filler(Restylane®) in treating nasolabial folds in Chinese population. Methods: 103 subjects in this study were recruited from five Chinese clinical trial centers between July 2014 and December 2015. Subjects were treated with hyaluronic acid dermal filler in correcting nasolabial folds and an optional re-treatment was performed after 12 months according to the subjects′wishes. The improved of nasolabial folds was evaluated by the change of severity (wrinkle severity rating scale, WSRS) and aesthetic improvement (global aesthetic improvement scale, GAIS). Satisfaction of subjects on treatment was evaluated using subject satisfaction questionnaires (SSQ). Safety indicators such as pain, skin and soft tissue presentation at the injection site were continuously evaluated throughout the whole treatment process. Results: Significant improvement in scores of WSRS and GAIS of all subjects was observed after treatment. Nine months after treatment, the scores of WSRS in 80 subjects (77.7%) and GAIS in 96 subjects (93.2%) were still improved. The 68 subjects (95.8%) received re-treatment after 12 months gained further improvement in nasolabial folds. Most adverse events were mild or moderate (transient/reversible local manifestations) and all resolved before study end, no severe adverse event related to products observed. Conclusions Hyaluronic acid dermal filler is effective and safe in treatment of nasolabial folds in Chinese population and the effect can last up to 12 months.

BACKGROUNDGlaucoma secondary to systemic lupus erythematosus (SLE) is an uncommon but serious complication that threatens vision and therefore cannot be neglected. A few cases of secondary glaucoma resulting from lupus-induced or iatrogenic ocular impairments have been reported in association with SLE. However, a systematic analysis of the diagnosis and treatment of glaucoma secondary to SLE has not been reported in the literature. The aim of this study is to further investigate the relationship between glaucoma and SLE.

METHODSIn this study, we reviewed nine eyes of five patients diagnosed with secondary glaucoma associated with SLE, including one case of neovascular glaucoma and four cases of steroid-induced glaucoma.

RESULTSNeovascular glaucoma was successfully treated by Ahmed glaucoma valve implantation surgery with adjunctive ranibizumab intravitreal injection, followed by panretinal photocoagulation (PRP). The steroid-induced glaucoma in eight eyes of four cases were controlled by trabeculectomy along with antiproliferative agents.

CONCLUSIONRegular follow-up ocular examinations should be conducted to ensure early diagnosis and treatment of secondary glaucoma in SLE patients to improve the prognosis of vision.

Objective To investigate the effect of laparoscope combined with ureteroscope for the treatment of hepatolithus. Methods 98 patients were randomly divided into two groups:the study group(laparoscope combined with ureteroscope group) and the control group (the open surgery group). The mean blood loss, the recovery of the stomach and intestines function, hospital stay and the rate of complications were observed. Results Compared with the open surgery group,the mean blood loss,the recovery of the stomach and intestines function,and hospital stay in the study group had statistically significant difference (all P＜0. 05). Compared with the open surgery group, the time of surgery and the patients carryingT tubes in the study group had statistically significant difference (all P＜0. 05). Compared with the open surgery group, the rate of gallstone removal、the rate of gallstone residual and the rate of injures in the study group had no statistically significant difference(all P＞0. 05). Conclusion Laparoscope combined with ureteroscope in patients with hepatolithus had the advantage of less trauma, faster postoperative recovery and fewer complications. It was safe and effective,so it was worth to recommend its clinical use.

ObjectiveTo investigate the role of platelet in mouse pulmonary microvascular endothelial cell (PMVEC) injury caused by lipopolysaccharide( LPS)-activated neutrophil.MethodsPMVECs were obtained from pathogen-free C3H/HeN mice of both sexes aged 6-8 weeks weighing 18-25 g according to the method described by Lim YC et al.Platelets and neutrophils were isolated from mouse blood by twice centrifugation and denaity gradient centrifugation respectively.PMVECs were seeded into twelve- or six-well plates ( 1 or 2 ml/well) after 2-5 passages and were randomly divided into 4 groups (n =31 each): group LPS; group platelets (group P);group neutrophils (group N) and group platelets + neutrophils (group PN).Each well contained about 5 × 107/ml platelets and/or 5 × 105/ml neutrophils respectively.PMVECs were incubated with LPS1 μg/ml at 37 ℃ in a 5％ CO2 humidified atmosphere for 1,6,12,18 and 24 h respectively in all 4 groups.The cells were examined with phase contrast microscope for morphological changes and survival condition.Viability rate,apoptotic rate and activation rate of PMVECs were detected by flow cytometry at each time points.ResultsThere was no significant difference in morphology and number of endothelial cells (ECs) among the 4 groups,while the number of activated ECs was significantly increased but the number of living cells decreased in group PN compared with group LPS.The activation rate of ECs was significantly higher after being incubated with LPS for 6-12 h in groups P and N than in group LPS.The viability rate was significantly lower,while the apoptotic rate and activation rate were significantly higher after ECs were incubated with LPS in group PN than in groups LPS,P and N.ConclusionPlatelets play a decisive role in mouse PMVEC injury induced by LPS activated neutrophils.
