Objective To study the levels of serum Periostin and interleukin(I1-)-18 in preterm infants with bronchopulmonary dysplasia(BPD),and to analyze their correlation with the severity of the disease and their predictive value for BPD.Methods A total of 62 preterm infants with BPD diagnosed and treated in the hospital from January 2019 to January 2022 were retrospectively selected as the BPD group,and 80 preterm in-fants without BPD during the same period were selected as the non-BPD group.According to the severity of BPD,the infants with BPD were divided into mild subgroup(22 cases),moderate subgroup(24 cases)and se-vere subgroup(16 cases).The serum levels of Periostin and IL-18 were detected by enzyme-linked immu-nosorbent assay.Pearson correlation analysis was used to analyze the correlation between the clinical parameters.Multivariate Logistic regression was used to analyze the influencing factors of BPD,and receiver operating characteristic(ROC)curve was used to analyze the predictive value of each indicator for BPD.Results Compared with the non-BPD group,the BPD group had a significantly higher proportion of infants with pulmonary surfactant(PS)use,neonatal respiratory distress syndrome,apnea,patent ductus arteriosus,and serum levels of Periostin and IL-18,as well as a significantly longer duration of mechanical ventilation,noninvasive respiratory support,and length of hospital stay.The lung function parameters[tidal volume per kilogram(VT/kg),ratio of time to peak tidal expiratory flow to time(TPTEF/TE),ratio of volume to peak tidal expiratory flow to volume(VPEF/VE),expiratory flow at 50％tidal volume(50％TEF),expiratory flow at 75％tidal volume(75％TEF)]and 1,5 min Apgar score of BPD group were lower than that of non-BPD group,and the differences were statistically significant(P＜0.05).The serum levels of Periostin and IL-18 in mild subgroup,moderate subgroup and severe subgroup were increased in turn.The levels of serum Periostin and IL-18 were negatively correlated with pulmonary function indexes(VT/kg,50％TEF,75％TEF,TPTEF/TE,VPEF/VE,P＜0.05).Serum Periostin,IL-18 and neonatal respiratory distress syndrome were independent risk factors for BPD(P＜0.05),and PS was a protective factor(P＜0.05).Serum Periostin,IL-18 and neonatal respiratory distress syndrome were independent risk factors for the severity of BPD(P＜0.05).The area under the curve(95％CI)of serum Periostin and IL-18 alone and in combination for predicting BPD were 0.841(0.814-0.899),0.863(0.820-0.897),0.922(0.878-0.949),respectively.The sensitivity and specificity of combined prediction were 0.902 and 0.825,respectively.The area under the curve of the combination of the two indica-tors for predicting BPD was greater than that of each index alone,and the difference was statistically signifi-cant(Z=5.357,4.894,P＜0.001).Conclusion The levels of serum Periostin and IL-18 are increased in in-fants with BPD,which are related to the severity of BPD and lung function.The combination of serum Perios-tin and IL-18 has a high predictive value for BPD.

Objective:To compare the clinical efficacy between arthroscopically assisted reduction versus open reduction in the treatment of paediatric humeral lateral condylar fractures with Kirschner wire fixation.Methods:A retrospective study was conducted to analyze the data of 28 children with humeral lateral condylar fracture who had undergone surgery at Department of Pediatric Orthopedics, Beijing Jishuitan Hospital from August 2023 to September 2023. There were 24 males and 4 females with an age of (6.5±1.6) years, 24 cases of type Ⅱ and 4 cases of type Ⅲ fractures according to the Jacob classification, and 1 case of type Ⅰ and 27 cases of type Ⅱ fractures according to the Milch classification. The time from injury to surgery averaged (71.6±21.3) hours. The children were divided into 2 groups according to their reduction methods: an arthroscopic group of 16 cases treated by arthroscopically assisted reduction and K-wire fixation and an open reduction group of 12 cases treated by open reduction and K-wire fixation. The operation time, incision length, Kirschner wire removal time, Mayo elbow performance score (MEPS) and the incidence of lateral bony spur on the X ray at the last follow-up were compared between the 2 groups; the flexion-extension and carrying angle of the elbow were compared between the healthy side and the affected side within each group at the last follow-up.Results:There was no significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). The 28 pediatric patients were followed up for (4.9±0.4) months after surgery. The incision length [(1.3±0.4) cm] and Kirschner wire removal time [(42.8±3.5) d] in the arthroscopic group were significantly shorter than those in the open reduction group [(4.8±0.5) cm and (95.5±16.4) d] ( P<0.05). There was no significant difference in the operation time between the 2 groups [(70.6±15.5) min versus (61.7±14.5) min] ( P>0.05). There was no significant difference in the flexion-extension or in the carrying angle between the healthy and affected sides within each group at the last follow-up ( P>0.05). There was no significant difference either in the MEPS score or in the incidence of lateral bony spur between the 2 groups at the last follow-up ( P>0.05). Follow-up revealed pin infection in 1 patient in the arthroscopic group, and exposure of Kirschner wire tail in 1 patient in the open reduction group. Conclusions:In the treatment of humeral lateral condylar fractures, arthroscopically assisted reduction and Kirschner wire fixation can allow for debridement of the fracture ends in a minimally invasive way, visual fracture evaluation and reduction. Compared with open reduction, arthroscopically assisted reduction can reduce operative trauma without significantly increasing operation time.

Long non-coding RNA (lncRNA) is an RNA molecule that does not code to express proteins, and plays an important role in the occurrence and development of a variety of tumors. As an lncRNA, SPRY4-IT1 is highly expressed in breast cancer tissues, and can be used as an upstream and downstream regulator of breast cancer, promoting the progression of breast cancer, and is closely related to breast cancer stage and prognosis. In-depth study of the molecular mechanism associated with SPRY4-IT1 and breast cancer can provide new ideas for discovering biomarkers for early diagnosis of breast cancer, assessing disease prognosis and finding targeting sites.

Objective:To explore the effectiveness of medial malleolus screw epiphyseodesis for pediatric ankle valgus correction and calculate the correction rate, and analyse the influence factors on deformity correction and the risk factors of deformity recurrence after screw removal.Methods:Medical records and radiographs of patients undergoing screw hemiepiphyseodesis of the medial physis of the distal tibia for ankle valgus between Jan 2011 and Dec 2020, at a single pediatric orthopedic department were retrospectively analyzed. A total of 41 patients (49 ankles) were included in following study, including 28 male patients and 13 female patients; with 24 left sides and 25 right sides. Median age at surgery was 10.75 (4.5, 13.9) years, and median follow-up time was 27 (12, 64) months. According to the clinical diagnosis: hereditary multiple exostoses were 23 ankles, fibula hemimelia were 5 ankles, tibia hemimelia were 2 ankles, endochondromatosis were 5 ankles, neurofibromatosis were 5 ankles, traumatic fracture were 6 ankles, and fibrous dysplasia were 3 ankles. The lateral distal tibial angle (LDTA) was measured on ankle weight-bearing X-ray to evaluate the deformity correction. Malhotra classification was used to describe shortening of the fibula at the ankle.Results:Eventually effective correction were obtained in 36 ankles, with an overall effective rate of 73.5%. Screw type (partial-thread or full-thread), screw length (whether to the contralateral cortex), washer used, clinical diagnosis, and age are not independent risk factors for effective correction. Multiple linear regression analysis ( R 2=0.67) was applied for postoperative correction amplitude in effective correction cases, and the length of correction time ( P<0.001), clinical diagnosis ( P=0.013) and preoperative LDTA ( P=0.002) were significant predictive factors after adjusting for age differences. One-way ANOVA were used to compare data between different clinical diagnosis, showed a significant difference in the mean postoperative correction rate ( F=5.05, P=0.003). Conclusion:Medial malleolus screw epiphyseodesis is an effective and reliable method for the treatment of ankle valgus deformity in children; different clinical diagnosis can produce significant differences in the correction rate of ankle valgus deformity.

Objective:To learn about the iodine nutritional status and the trend of iodine deficiency disorders in key populations in Changchun City, so as to provide basis for timely adoption of targeted prevention measures and scientific adjustment of intervention strategies.Methods:From 2018 to 2020, 10 counties (cities, districts) under the jurisdiction of Changchun City were divided into 5 sampling areas according to the directions of east, west, south, north and middle. One township (street) was randomly selected from each area, and 20 pregnant women and 40 non-boarding students aged 8 to 10 (half male and half female) of one primary school were selected from each township (street). Household salt samples and a random urine sample of pregnant women and children were collected for detection of salt iodine and urinary iodine; thyroid volume was checked in children aged 8 to 10.Results:From 2018 to 2020, the median range of edible salt iodine in children's home in Changchun City was 23.7 - 23.9 mg/kg, and the consumption rate of qualified iodized salt was 96.6%, 94.7% and 96.5%, respectively. The median range of edible salt iodine in pregnants' home was 23.7 - 25.3 mg/kg, and the consumption rate of qualified iodized salt was 97.6%, 95.9% and 96.1%, respectively. From 2018 to 2020, the median urinary iodine of children in Changchun City was 170.1, 192.7 and 175.2 μg/L, respectively, and the iodine nutritional status were all the appropriate level. The areas with the appropriate level of iodine each year accounted for 90% (9/10), 70% (7/10) and 80% (8/10), respectively, and the rest were exceeding the iodine appropriate areas. The median urinary iodine of pregnant women was 151.6, 163.1 and 161.0 μg/L, respectively, and the iodine nutritional status were all the appropriate level. The areas with the appropriate level of iodine each year accounted for 50% (5/10), 60% (6/10) and 60% (6/10), respectively, and the rest were all iodine deficient areas. A total of 2 000 children aged 8 to 10 were examined for thyroid volume, 3 cases of goiter were detected, and the goiter rate was 0.15%.Conclusion:From 2018 to 2020, the consumption rate of qualified iodized salt, urinary iodine level and goiter rate of children of key populations in Changchun City have reached the elimination standard of iodine deficiency disorders, but there is a risk of iodine deficiency in pregnant women in some areas.
