ObjectivesTo evaluate the predicting value of bedside pulmonary ultrasound in bronchopulmonary dysplasia (BPD) in premature infants.MethodsPremature infants with gestational age below 28 weeks or birth weight below 1 500 g admitted to NICU of Chengdu Women and Children’s Central Hospital from June 2018 to June 2019 were included. Pulmonary bedside ultrasound monitoring was performed on the 3rd, 7th, 14th and 28th day after admission, and the characteristic ultrasound images were recorded and scored. BPD were diagnosed by NICHD standard. The clinical data and pulmonary ultrasound data were compared and analyzed. Then diagnostic value of bedside pulmonary ultrasound in BPD of premature infants were analyzed.ResultsA total of 81 children involving 32 BPD and 49 non-BPD were included. The sensitivity (Sen), specificity (Spe) and area under curve (AUC) of receiver operating characteristic (ROC) of the "alveolar-interstitial syndrome" within 3 days after birth and the "fragment sign" on 28 days after birth were 81.25%, 51.02%, 0.66 and 31.25%, 97.96%, 0.65, respectively. The lung ultrasound scores in the BPD group on the 3rd, 7th, 14th, and 28th day after birth were 71.99.%, 68.39%, 0.71; 87.50%, 57.14%, 0.72; 78.13%, 73.47%, 0.76 and 56.25 %, 75.51%, 0.66. Sen, Spe and ROC AUC of comprehensive evaluation of lung ultrasound predicted the occurrence of BPD been 81.25%, 63.27%, and 0.85.ConclusionsThe comprehensive evaluation of combination of "alveolar interstitial syndrome" image characteristics within 3 days after birth, "fragment sign" image characteristics after 28 days, and lung ultrasound score at different times after birth can predict the premature infants with bronchopulmonary dysplasia.

Objective To discuss how is the perinatal infant’s prognosis influenced by different cardiac function and types of heart disease in pregnant women with heart disease, and to check the importance of antenatal examination. Method Retrospective analyses were conducted on the clinical records of 102 pregnant women hospitalized due to heart disease from February 2002 to February 2011 in the First Affiliated Hospital of Xinjiang Medical University. According to the level of cardiac function, 61 patients were divided into the Level I-II group and the other 41 patients were in the Level III-IV group. Results Of all cases, 38 were congenital heart disease (37.25%), followed by 22 arrhythmia (21.57%), 17 rheumatic heart disease (16.67%), 15 perinatal cardiomyopathy (14.71%), 7 hypertensive heart disease and 3 other types of heart disease. The average gestational weeks were shorter and the neonate’s weight was lower in the Level III-IV group than the Level I-II group, with a significant difference (Plt;0.05); the incidence of premature delivery, low birth weight infant at normal gestational age, neonatal asphyxia and perinatal mortality was higher in the Level III-IV group than the Level I-II group, with a significant difference (Plt;0.05); the rate of regular antenatal examination was higher in the Level III-IV group than the Level I-II group, with a significant difference (P=0.008); and there were significant differences between the regular and irregular examination groups in the incidence of premature delivery and low birth weight infant at normal gestational age (Plt;0.05), but no significant differences were found in the incidence of asphyxia and perinatal mortality (Pgt;0.05). Conclusions Congenital heart disease is the most commonly-seen type in the pregnant women with heart disease. The maternal cardiac function directly impact the prognosis of perinatal infant, and the regular antenatal examination, timely diagnosis and treatment can improve pregnancy outcome.
Objective To investigate the safety and effect of same-day discharge in injection sclerotherapy for children with hemangioma (IJCH) and tension-free hernioplasty for adults with inguinal herinia (TFHA). Methods A retrospective analysis was conducted on patients undergoing IJCH or TFHA in the Day Surgery Center of West China Hospital of Sichuan University between November 2020 and October 2021. According to the patient’s condition and willingness, they were divided into same-day discharge group (162 children and 180 adults) and overnight hospitalization group (68 children and 271 adults). The amount of intraoperative bleeding, length of hospital stay, hospitalization expenses, pain before discharge, and short-term postoperative complications were compared between the two groups. Visual analogue scale was used for pain assessment in adults and children over 6 years old, and smiley face score was used in children below 6 years old. Results Compared with those in the overnight discharge group, the amount of intraoperative bleeding in the same-day discharge group was less [IJCH: (0.45±0.05) vs. (2.76±1.21) mL, P<0.05; TFHA: (1.20±0.05) vs. (6.76±2.30) mL, P<0.05], length of hospital stay was shorter [IJCH: (7.99±1.22) vs. (23.10±1.42) h, P<0.05; TFHA: (6.13±1.79) vs. (22.75±1.80) h, P<0.05], hospitalization cost was lower [IJCH: (5094.00±1320.14) vs. (6263.52±1220.20) yuan, P<0.05; TFHA: (7199.21±1535.84) vs. (7976.82±1967.82) yuan, P<0.05], pain before discharge was milder (IJCH: 0.05±0.02 vs. 0.50±0.01, P<0.05; TFHA: 1.20±0.01 vs. 2.01±0.20, P<0.05). There was no significant difference in the incidence of postoperative complications or unplanned revisit within 30 days between the two modes (P>0.05). Conclusions The same-day surgery mode is safe and feasible in IJCH and TFHA, and can shorten the length of hospital stay and reduce the cost of hospitalization. It is suggested to popularize this mode in clinical practice.
Objective To assess the growth station, the upper respiratory infection frequency and consultation frequency of the geographically defined high risk neonatal population at 1-year-old based on both birthweight and gestational age. Methods All infants admitted in our hospital from May in 2008 to May in 2009 were divided into three groups according to gestational age and birth weight, that were, group 1: born lt;32 completed gestational weeks and weighing ≥1 500 g; group 2: born after 32 completed gestational weeks and weighing lt;1 500 g; and group 3: born lt;32 completed gestational weeks and weighing lt;1 500 g. Information at 12 months corrected age about growth, the upper respiratory infection frequency and consultation frequency was collected. Results The growth rate of weight and head circumference in group 3 were lower than that in group 1, and the length growth rate was lower than that in group 1 and group 2. Infants in group 3 suffered from more airway infections (median: 15.5) than in group 1 (12.5) and group 2 (8.5). Infants in group 3 needed more medical consultations (median: 27.5) than those in group 1(17.5) and group 2 (15.5). Conclusions This study gives estimates for growth outcome, airway infection and consultation frequency at 12 months corrected age for very low birthweight infants (lt;1 500 g) and for very preterm infants (lt;32 completed gestational weeks). Gestational age and birth weight are the same important for predicting infants’ outcome and should therefore be integrated into clinical statistics.
ObjectiveTo systematically review the effectiveness and safety of interventions which target to improve the rate of successful extubation in preterm infants.MethodsPubMed, Web of Science, Cochrane Library, Chongqing VIP database, China National Knowledge Infrastructure, and Wanfang Database were searched for articles published from the dates of establishment of databases to August 2020, which compared different noninvasive respiratory support models or different doses of caffeine to improve the rate of successful extubation in preterm infants in randomized controlled trials. The references of included articles were also retrieved. And then a meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 33 randomized controlled trials involving 4 536 preterm infants were included. Compared with nasal continuous positive airway pressure (NCPAP), high-flow nasal cannula (HFNC) reduced the nose injury rate [odds ratio (OR)=0.29, 95% confidence interval (CI) (0.15, 0.57), P=0.000 3] and the pneumothorax rate [OR=0.18, 95%CI (0.06, 0.55), P=0.003]; nasal intermittent positive pressure ventilation (NIPPV) reduced the extubation failure rate [OR=0.33, 95%CI (0.23, 0.48), P<0.000 01], the reintubation rate [OR=0.36, 95%CI (0.20, 0.65), P=0.000 7], the respiratory failure rate [OR=0.33, 95%CI (0.17, 0.64), P=0.000 9], and the pneumothorax rate [OR=0.29, 95%CI (0.12, 0.70), P=0.006]; and biphasic positive airway pressure (BiPAP) reduced the reintubation rate [OR=0.21, 95%CI (0.09, 0.46), P=0.000 1]. Compared with low-dose caffeine, high-dose caffeine reduced the extubation failure rate [OR=0.44, 95%CI (0.32, 0.60), P<0.000 01] and the bronchopulmonary dysplasia rate [OR=0.69, 95%CI (0.48, 0.99), P=0.04], but increased the rate of tachycardia [OR=1.99, 95%CI (1.22, 3.25), P=0.006].ConclusionAccording to the current evidence, compared with NCPAP, NIPPV and BiPAP could be used to improve the rate of successful extubation in preterm infants, HFNC could be used to decrease the risk of nose injury and pneumothorax; the optimal dose of caffeine should be chosen after evaluating the risk of adverse reactions such as tachycardia.

Methods: We chose the 56 infant patients who suffered from repeated pneumonia as the observe group while the 60 health infants as the comprise group, then test the content of cadmium， plumbum， cuprum， zinc， calcium， magnesium and ferrum in blood. Results: The content of zinc and ferrum in the patient’s blood was lower than the comparison group, and the P value was Plt;0.01 and Plt;0.05 respectively, there was obvious differentiation between the two groups. Conclusion: Occurence of part repeated pneumonia is related to the deficiency of the microelements zinc and ferrum in blood. We should detect the common content of microelement to the infant patients who suffer the repeated pneumonia, and give a complement treatment to the microelements’ deficiency infant patients.
Objective To guide blood glucose management during pregnancy and reduce the incidence of long-term complications of the fetus by exploring the long-term growth condition of offspring of pregnant women with gestational diabetes mellitus. Methods A total of 180 cases full-term newborns of pregnant women with gestational diabetes mellitus from December 25th, 2011 to December 25th, 2012 were selected as the diabetes group. Another 200 newborns of pregnant women without any complications were randomly collected as the control group. Birth weight, gestational age, sex, blood glucose, and 24-, 48-, 72- and 120-hour transcutaneous bilirubin value after the birth of the newborns were recorded; weight, height, body mass index (BMI), triglycerides, total cholesterol, high density lipoprotein (HDL), low density lipoprotein, blood pressure and fasting plasma glucose quota between the two groups were contrasted when the children were three years old. Results There were no significant difference in the birth weight, gestational age and sex between the diabetic and the control group. The blood glucose levels of the newborns in the diabetic group was significantly lower than that in the control group (P<0.05). The 24-, 48-, 72- and 120-hour transcutaneous bilirubin values of the newborns in the diabetic group were significantly higher than those of the control group (P<0.05). The weight, height and BMI of the three years old offspring in the diabetic group were significantly higher than those in the control group (P<0.05). There were no significant difference in triglycerides, total cholesterol, HDL, Low density lipoprotein, fasting plasma glucose quota, and systolic blood pressure between the diabetic group and the control group (P>0.05), but the diastolic blood pressure in the diabetic group was much higher than that in the control group (P<0.05). Conclusion The impact of gestational diabetes mellitus on offspring of pregnant women was not only in the fetus and newborn period, but also in the future, which should be timely intervened.
Severe psychomotor developmental delay resulting from early postnatal (within 3 months) seizures can be diagnosed as Early-Infantile Developmental and Epileptic encephalopathies (EIDEE). Its primary etiologies include structural, hereditary, metabolic and etc. The main pathogenesis may be related to the inhibition of normal physiological activity of the brain by abnormal electrical activity and the damage of the brain neural network. Ohtahara syndrome and Early Myoclonic Encephalopathy (EME) are typical types of EIDEE. The principle of treatment is to improve the cognitive and developmental function by controlling frequent seizures. When the seizure is difficult to control with drugs, surgical evaluation should be performed as soon as possible, and surgical treatment is the first choice for patients suitable for surgery. The types of surgery can be divided into excision surgery, dissociation surgery, neuromodulation surgery and etc. The current status of surgical treatment of EIDEE was described, and the curative effect of surgical treatment was explored, so as to help clinicians choose appropriate treatment methods.
ObjectiveTo investigate the postnatal changes in urinary metabolic amino acid levels in infants with retinopathy of prematurity (ROP) and their effect on ROP, and to analyze the amino acid metabolic pathways that may be involved in the development of ROP. MethodsA retrospective cohort study. From January 2020 to December 2023, 65 premature infants with severe ROP (ROP group) who were hospitalized, born with gestational age ＜32 weeks in Children's Hospital Affiliated to Zhengzhou University were included in the study. Fifty premature infants with matched sex and gestational age and no ROP were selected as the control group. Urine amino acids and their derivatives were detected by gas chromatography-mass spectrometry. The two groups were compared by independent sample t test. The metabonomics of urinary amino acids was analyzed by orthogonal partial least squares discriminant analysis (OPLS-DA) model. The variable projection importance (VIP) score ＞1 suggested that the substance was two groups of differentially expressed amino acids. The predictive value of urinary amino acids for severe ROP was compared by using the receiver's operating characteristic (ROC) curve and the area under the curve. After t test and metabolomics analysis, the two groups of amino acids with large differences were normalized and compared by Pearson correlation analysis. The Kyoto Encyclopedia of Genes and Genomes database was used to analyze the metabolic pathways of differentially expressed amino acids involved in ROP. ResultsCompared with the control group, the concentrations of oxalic acid -2 and thiodiacetic acid-2 in urine metabolites of children in ROP group were significantly decreased, while the concentrations of 4-hydroxybutyric acid-2, 3-methylpentadienoic acid-2(1), 2-ketoglutarate-ox-2(2) and 3, 6-epoxy-dodecanedioic acid-2 were significantly increased, with statistical differences (t=0.036, 0.005, 0.038, 0.032, 0.022, 0.011; P＜0.05). The results of OPLS-DA analysis showed that amino acids of urinary metabolites in ROP group and control group were distributed in the left and right regions of the scatter plot, and there was a satisfactory separation trend between the two groups (R2Ycum=0.057 4, Q2cum=0.025 7, P＜0.05). As shown in the S-Plot, the amino acids biased towards two stages are glycolic acid-2, phosphoric acid-3, oxalic acid-2, thiodiacetic acid-2, 4-hydroxybutyric acid-2, 3-methylcrotonylglycine-1, 3-methylpentadienoic acid-2(1), 2-ketoglutarate-ox-2(2) and 3, 6-epoxy- dodecanedioic acid-2, respectively. Eleven differentially expressed amino acids with VIP score ＞1 were screened, among which the highest VIP score was oxalate-2, glycerate-3, phosphoric acid-3, 3-methylcrotonylglycine-1, uranoic acid -3 and thiodiacetic acid-2. The difference of amino acid concentration between the two groups was the highest in 4-hydroxybutyric acid-2 and thiodiacetic acid-2. The correlation between oxalic acid-2 and glycerate-3 was the highest (r=0.830, P＜0.001), and most amino acids were positive correlated. ROC curve fitting analysis showed that the combined prediction of 11 differenly-expressed amino groups had the largest area under the curve (0.816), the cutoff value was 0.531, and the sensitivity and specificity were 83.1% and 70.0%, respectively. The enrichment analysis of these 11 amino acids with significant differences suggested that the main pathways involved included butyrate metabolism, glyoxylic acid and dicarboxylic acid metabolism and lipoic acid metabolism. ConclusionAbnormal amino acid metabolism of 4-hydroxybutyrate-2, 3-methylpentadienoic acid-2(1), thiodiacetic acid-2, 2-ketoglutarate-ox-2(2), 3, 6-epoxy-dodecanedioic acid-2 may have a certain effect on the occurrence of ROP.
