RESUMO
Objective:To determine the risk factors of perioperative cerebral oxygen supply and utilization and cerebral activity in newborns with congenital heart disease(CHD).Methods:In this prospective cohort study, NIRS and amplitude integrated EEG(aEEG) performed before and after surgery were used to assess cerebral oxygen supply and utilization and cerebral activity in these newborns. Cerebral tissue oxygenation index(TOI) and fractional tissue oxygen extraction(FTOE) measured from NIRS for each patient were compared to background pattern and SWC of aEEG before and after surgery. Analysis included clinical characteristics and explore the risk factors of TOI, FTOE.Results:90 CHD newborns were obtained. Pre- and postoperative TOI were 0.56±0.05 and 0.59±0.03, both of them were lower than the average for normal newborns( P<0.05). Pre- and postoperative FTOE were 0.36±0.07 and 0.39±0.04. TOI and FTOE were significantly improved after surgery( P<0.05). There was negative correlation between the TOI improvement after surgery and SpO 2 of right upper limb( β: -0.202). Patient with Respiratory support before surgery had lower preoperative TOI levels( β: -0.879). Preoperative SpO 2 was higher, then preoperative TOI was also higher( β: 0.214). The postoperative FTOE of who had lower amplitude showed by aEEG was significantly lower( P<0.05). The postoperative TOI of who had immature SWC was lower than mature SWC( P<0.05). Delayed chest closure was a risk factor for postoperative death. Conclusion:TOI in children with CHD improved significantly after operative, especially in patient with cyanosis CHD. Preoperative TOI is positively related to SpO 2. It’s positive correlation between cerebral activity and cerebral oxygen utilization. The patient who has immature SWC showed lower cerebral oxygen supply. Monitoring cerebral activity and oxygenation may be useful in perioperative management and cerebral protection of newborns with CHD.

RESUMO
Objective To investigate the correlation between the indications,findings,interventions of fibrobronchoscopy(FB) in neonates and their correlative diseases with neonatal FB results and clinical data.Methods Retrospective case series of 243 consecutive patients of 28 days old or younger were investigated underwent FB for the first time from January 2010 to December 2014,at a tertiary care hospital.The common indications for FB and detection rate of respiratory tract diseases were collected.If the findings of FB had significant associations with premature birth and other diseases were analyzed.Associations between interventions and basic illnesses were also analyzed.Results Of the 243 patients undergoing 275 procedures of FB,201 cases were boys(73.1％).The age of FB was (13.34 ± 9.76) days and the weight was (3.08 ± 0.68) kg.Forty-five cases were premature infants (16.4％).A total of 254 procedures were found to have congenital diseases (92.4％),and 177 cases of them had congenital heart diseases (CHD) (64.4％).Common indications for FB were dyspnea(140 cases,50.9％),tachypnea(82 cases,29.8％),and stridor(71 cases,25.8％).A total of 188 upper airway lesions were found and the most common findings were laryngomalacia(56 cases,20.4％) and vocal cord paralysis(bilateral/unilateral,50 cases,18.2％).A total of 315 lower airway lesions were found and the most common findings were airway mucosal inflammation (98 cases,35.6％),trachea and main bronchial stenosis (73 cases,26.5 ％).A total of 21 cases (7.6％) underwent supraglottoplasty during or after FB,while 17 cases (6.2％) underwent tracheal dilation and 10 cases (3.6％) underwent tracheotomy.Compared with non-CHD neonates,neonates with CHD were statistically significantly less likely to have congenital lesions statistically,such as laryngomalacia(15.8％ vs.28.6％,P =0.012),bilateral vocal cord lesions(6.2％ vs.21.4％,P =0.000) and congenital laryngeal dysplasia(0 vs.7.1％,P =0.001).The tracheotomy(0 vs.10.2％,P =0.000) and supraglottoplasty(2.3％ vs.17.3％,P =0.000) were more rare.Nevertheless,they were more likely to have secondary lesions such as the left main bronchial stenosis caused by extrinsic compression (23.7％ vs.1.0％,P =0.000),abnormal bronchial anatomy(9.6％ vs.2.0％,P =0.018),left vocal cord paralysis(9.0％ vs.1.0％,P =0.008) and airway mucosal inflammation(41.8％ vs.24.5％,P =0.004).The tracheostenosis and main broncial stenosis (37.3％ vs.7.1％,P =0.000) with long-term intubation(78.5％ vs.58.2％,P =0.000) were more common.There was no significant difference between term neonates and premature infants in the detection rate of respiratory tract diseases (P ＞ 0.05),tracheotomy (0 vs.4.3 ％,P =0.322),supraglottoplasty (13.3 ％ vs.6.5 ％,P =0.205) or long-term i ntubation (80.0％ vs.69.6％,P =0.157).Complications caused by procedure were rare and mild.Conclusions FB can detect whether the neonates with dyspnea,tachypnea and stridor have laryngomalacia,vocal cord paralysis,airway mucous edema,tracheal and main bronchial stenosis and other signs,and FB may play an important role in diagnosis,treatment and prognosis evaluation of neonatal respiratory diseases.
RESUMO
Objective To determine the long term outcomes of laryngomalacia infants with anomalies and to determine the clinical practice guideline for these infants.Methods The charts of infants with moderate to severe laryngomalacia,who were admitted to our hospital between January 2013 and December 2015,were retrospectively reviewed.These infants were divided into two groups,anomaly(A) group(n=37) and non-anomaly (NA) group(n=19).Results Fifty-six cases were enrolled.Infants in A group were older at symptom relief than those in NA group[(10.00±3.56) months vs.(7.89±3.03) months,P＜0.05],and the weight percentiles of infants in A group were lower at 3,6 and 12 months than those in NA group(P＜0.05).There was no statistically significant difference between the two groups on the weights percentiles in infants at 24 months after diagnosis.Five of 37 cases in A group and 3 of 19 cases in NA group had supraglottoplasty.One infant in A group had tracheotomy.Conclusion Both breathing difficulty and development retardations of infants with moderate or severe laryngomalacia could gradually improved with age.There is not enough evidence to support the aggressive supraglottoplasty for infants with anomalies and laryngomalacia.

RESUMO
Objective To explore the effect of repaglinide intensive treatment on islet β-cell function and long-term control of blood glucose in newly diagnosed type 2 diabetic patients. Methods Self-control and inter-group control prospective study was conducted in 80 newly diagnosed type 2 diabetic patients who were treated with short-term repaglinide intensive treatment and islet β-cell function was assessed by 75 g oral glucose tolerance test (OGTT) before and after repaglinide treatment. The changes of △I30/△G30 ratio, blood lipid, HOMA A and HOMA B were examined. Results After treatment, in successful group, middle group and defeat group, the fasting plasma glucose levels were decreased from 8.9±1.5, 8.6±1.6,9.0±2.0 to 5.0±1.4,6.3±0. 7,6.5±0. 9 mmol/L, 0. 5 h postprandial glucose levels were decreased from (12.6±1.6, 12.6±1.5, 12.4±1.3 to 8.4±1.0, 6.8±0. 7, 8. 6±0. 9)mmol/L,and 2 h postprandial glucose levels were decreased from (13.0±1.2, 13. 1±1.3, 13. 3±1.4 to 9.2±0.9, 6.6±0. 7, 9.2±0. 9)mmol/L,respectively (all P <0. 005). The ratio of △I30/△G30 was increased froml. 69±0. 31, 1.72±0. 33, 1.79±0. 36 to 4. 47±0. 62, 4. 42±0.46,12. 00±0.46 in the three groups, respectively (P<0.05). HOMA B was significantly improved (P<0. 05), while triglycerides and HOMA A were decreased(P<0. 05). The levels of fasting blood glucose and postprandial blood glucose in 21 patients were maintained within normal range for more than six months. There were significant differences in the ratio of △I30/△G30, age, repaglinide dosage and the time of reaching target of glucose [4.47±0.62 vs. 2. 0± 0.46; 39±8 vs. 56±9; 2.0±1.5 vs. 5.0±2.5; 32.4±8.0 vs. 53.3±7.6; all P<0.05] between successful group and defeat group. Conclusions The short-term intensive treatment with repaglinide can significantly improve the early secretion phase of insulin and the islet β-cell function, reconstruct of the physiological model of insulin secretion and relieve the disease.
