RESUMEN
Objective To explore the clinical characteristics and genetic mutation types of the Mediterranean anemia in Guangxi region in the early neonatal period.Methods The observation group was the children who hospitalized in the Maternal and Child Health Hospital of Guangxi Zhuang Autonomons Region during the period of January 2013 and November 2015,and diagnosed Mediterranean anemia were 85 cases.And 85 newborns that were in the hospital at the same time were selected as the control group.The matching condition between the observation group and the control group was the gestational age.We retrospectively analyzed the general situation (birth weight and gender) and the treatment procedure (the characteristic of blood routine examinations;the day-old of the onset of anemia;the endurance of jaundice;assisted ventilation;the time of oxygen therapy;the dayold of enteral feeding;the blood transfusion times) of the two groups.And the gene was detected in the observation group.Results The observation group's days of life [(13.00 ± 3.79) d] of the oral feeding were higher than that [(9.33 ± 1.95) d] of the control group's (t =2.730,P ＜ 0.05);the observation group's frequency [(3.0 ± 1.0) times] of the blood transfusion was higher than that [(1.0 ± 0.2) times] of the control group's (t =4.268,P ＜ 0.05).The observation group's days of life [(4 ± 1) d] of anaemic onset was shorter than that [(8 ± 2) d] of the control group's (t =-3.258,P ＜ 0.05).The mean corpuscular volume [(80 ± 12) fl] in the blood routine of the observation group was smaller than that [(91 ± 28) fl] of the control group (t =6.712,P ＜ 0.05).In the observation group,the mother's age of pregnancy was (29.19 ± 0.91) years,the birth weight of the newborns was (2.356 ± 0.748) kg,the service time of the ventilator was (7.11 ± 5.07) h,the time of continue positive airway pressure was (27.40 ± 15.17) h,the time of the oxygen provision was (84.98 ± 30.65) h,the time of duration of the jaundice last was (10 ± 3) d;and in the control group,the mother's age of pregnancy was (27.9i ± 0.88) years,the birth weight of the newborns was (2.507 ± 0.783) kg,the service time of the ventilator was (6.21 ± 2.55) h,the time of continue positive airway pressure was (9.64 ± 4.89) h,the time of the oxygen provision was(63.07 ± 21.87) h,the time of duration of the jaundice last was (15 ± 2) d.The parameters showed above were not statistically different between the two groups (all P ＞ 0.05).In 85 cases the detection of α-thalassemia in 60 cases,24 patients with β-thalassemia,1 cases of α-thalassemia combined with β-thalassemia.The logistic regression analysis showed that the age of the oral feeding completely (OR =0.233,95％ CI =0.081-0.673) and the times of blood transfusion (OR =6.621,95％ CI =2.777-15.784) were the independence factors of the Mediterranean anemia.Conclusion The early clinical performance of Mediterranean anemia is lack of specificity,and we must improve genetic testing and regulate blood transfusion as soon as possible to the one who has anemia and other clinical manifestations within a week immediately following birth or who is suspected of Mediterranean anemia patients by the blood routine examination.
RESUMEN
Objective To study the risk factors and prognosis of very/extremely low birth weight preterm (VLBW/ELBW) infants with bronchopulmonary dysplasia (BPD) during the first three years of life.Method From January 1st to December 31st,2012,a retrospective study was conducted on the VLBW/ELBW preterm infants with ＞ 28 days of hospitalization in the NICU of our hospital.The infants were assigned into BPD group (FiO2 ＞ 21％) and non-BPD group depending on the oxygen requirement on the 28th day after birth.The incidences of bronchitis,pneumonia,wheezing and re-hospitalization during the first three years of life were analyzed.The pulmonary function tests were performed at one-year-age.Independent-sapmles t test,Kruskal-wallis test and x2 test were used to compare the results between the two groups.Result A total of 72 patients were enrolled into this study.34 patients in the BPD group and 38 in the non-BPD group.The gestational age,birth weight and the use of INSURE technique of BPD group were significantly lower than non-BPD group,while the duration of hospital stays were longer than non-BPD group (P ＜0.05).The ratio of male,neonatal respiratory distress syndrome (RDS),patent ductus arteriosus (PDA),intrauterine infection,mechanical ventilation,nosocomial infection and the inhalation of high concentrations of oxygen were significantly higher in BPD group than non-BPD group (P ＜ 0.05).Incidences of bronchitis and wheezing during 0 ～ 1,1 ～ 2 and 2 ～ 3 years of age in the BPD were significantly higher than non-BPD group,separately.No significant differences existed in the incidences of pneumonia and re-hospitalization between the two groups.Pulmonary function test showed that the respiratory rate (RR) and peak tidal expiratory flow in the BPD group were significantly higher than non-BPD group,while the tidal volume,peak expiratory time and peak expiratory volume were significantly lower in BPD group than non-BPD group (P ＜ 0.05).Conclusion BPD often occurs in preterm infants with gestational age less than 32 weeks.It may cause impaired pulmonary function,characterized by obstruction in small airway,and increases the risk of bronchitis and wheezing during the first three year of life.

RESUMEN
Objective To explore the etiologies and characteristics of esophageal motility in patients with non-obstructive dysphagia by esophageal high-resolution manometry (HRM).Methods From November 2011 to August 2015,233 patients with non-obstructive dysphagia diagnosed by HRM were retrospectively analyzed.All the patients received gastroendoscopy to exclude obstructive dysphagia.Results Among 233 patients with non-obstructive dysphagia,there were 160 cases of achalasia,38 cases of nonspecific esophageal motor disorder (13 cases of low amplitude peristalsis or absent peristalsis,seven cases of synchronous contraction or rapid contraction,three cases of distal esophageal spasm,six cases of increased resting upper esophageal sphincter pressure (UESP),three cases of reduced UESP,six cases of lower esophageal sphincter (LES) incomplete relaxation),five cases of gastroesophageal reflux disease,four cases of scleroderma,two cases of Jackhammer esophagus,and 24 cases with normal esophageal motility.Conclusions Achalasia is the most common cause of non-obstructive dysphagia,followed by nonspecific esophageal motor disorder.Esophageal HRM is an important method for the diagnosis of nonobstructive dysphagia,especially for unexplained dysphagia.
RESUMEN
Objective To investigate the image quality and radiation dosage of the prospective ECG-triggered 256 multi-slice computer tomography (MSCT) angiography in accessing coronary artery (CA) on children.Methods Coronary arteries of ninety-three children were evaluated using prospective ECG-triggered 256-MSCT with the same system setting.Seventy-four patients had the heart rate records and a four-point scoring system was applied to study the capability of MSCT in detecting CA.The signal,noise and contrast-to-noise ratio (CNR) were analyzed to investigate the association of image quality with age (n =74).Then volumetric CT dose index (CTDIvol),dose-length product (DLP) and effective dose (E) were utilized to study the association of radiation dosage with age (n =93).Results On 74 patients with heart records,the detection rate for original,proximal,middle,distal and all 11 segments of CA was 100％,97％,92％,78％ and 91％,respectively.No influence of age was found on their detection (all P＞0.05).E of group A,B,C and D were 1.8,1.3,0.8 and 0.7 mSv,respectively.A strong negative correlation was found between E and age (r =-0.803,P ＜ 0.01).Higher DLP was found on elder patients,though no correlation was found between ages vs.DLP(r =0.124,P ＞ 0.05).No correlation was found between noise vs.age (r =0.041,P ＞ 0.05).Significantly larger signals,CNR and E(t =3.386,2.073,3.825,P ＜ 0.05) were found on younger patients (age ＜ 3 years).Conclusions Prospective ECG-triggered 256-MSCT has considerable performance for the evaluation of coronary arteries on children.However,children under the age of 3 are not recommended for this examinary,but for examination on children ≥ 8-year old,the tube current could be further needed.

Objective To establish biological reference intervals of neonatal T lymphocyte subsets and IgG, IgA,IgMlevels in 24 -hour newborns in Guangxi.Methods Maternal history and neonatal clinical data were evalua-ted and recorded.Venous blood samplings were collected within 24 hours of birth and were sent for testing in half an hour.The neonates were divided into the early -preterm,the late -preterm and the term neonates group,1 1 0 cases for each group.The parturients were divided into Dexamethasone treatment group and without Dexamethasone treatment group.Data in neonates and the parturients and the sex were analyzed by SPSS 1 7.0 software and the biological refe-rence values were calculated.Results The two -sided reference intervals of 95% in the early -preterm group,the late -preterm group and the term neonates group were as follows:CD3 +:52.07 -88.92 g/L,58.1 6 -90.42 g/L, 56.1 5 -95.67 g/L;CD4 +:25.20 -59.26 g/L,31 .27 -72.91 g/L,28.44 -82.66 g/L;CD8 +:7.30 -36.26 g/L, 9.1 3 -38.49 g/L,1 1 .09 -48.99 g/L;CD4 +/CD8 +:0.34 -4.58,0.34 -4.58,0.32 -3.80;CD1 9 +:3.95 -27.59 g/L,4.04 -30.94 g/L,4.08 -38.70 g/L;NK cell:1 .34 -6.64 g/L,2.88 -8.92 g/L,3.07 -9.35 g/L;IgA:0.000 4 -0.039 6 g/L,0.000 0 -0.069 0 g/L,0.000 0 -0.069 0 g/L;IgM:0.001 6 -0.1 58 4 g/L,0.020 0 -0.1 40 0 g/L,0.020 0 -0.420 0 g/L;IgG:3.22 -1 0.98 g/L,1 .1 0 -1 4.62 g/L,5.00 -1 3.66 g/L.Moreover the ca-ses with Dexamethasone treatment were as follows:the late -preterm infants CD8 + 1 0.35 -40.33 g/L,NK 3.1 0 -9.46 g/L,term NK 6.60 -9.50 g/L;those in without Dexamethasone treatment:the late -preterm infants CD8 +8.42 -34.96 g/L,NK 2.94 -7.80 g/L,term NK 2.98 -8.94 g/L;according to gender,the males in the late -pre-term infants CD8 + 8.26 -35.66 g/L,term CD3 + 51 .90 -92.94 g/L;females in the late -preterm infants CD8 +1 1 .08 -40.68 g/L,term CD3 + 61 .1 0 -96.1 4 g/L.Conclusions Testing values of neonatal T lymphocyte subsets and IgG,IgA,IgM levels in 24 -hour newborns in Guangxi disperse largely and show some differences among the early -preterm neonates,the late -preterm neonates and the term neonates,and maternal Dexamethasone treatment during pregnancy and gender play a role in neonatal immunity.
RESUMEN
In this paper, we present a virtual endoscopy (VE) for diagnosis of heart diseases, which is proved efficient and affordable, easy to popularize for viewing the interior of the heart. The dual source CT (DSCT) data were used as primary data in our system. The 3D structure of virtual heart was reconstructed with 3D texture mapping technology based on graphics processing unit (GPU), and could be displayed dynamically in real time. When we displayed it in real time, we could not only observe the inside of the chambers of heart but also examine from the new angle of view by the 3D data which were already clipped according to doctor's desire. In the pattern of observation, we used both mutual interactive mode and auto mode. In the auto mode, we used Dijkstra Algorithm which treated the 3D Euler distance as weighting factor to find out the view path quickly, and, used view path to calculate the four chamber plane.

ObjectiveTo evaluate the feasibility and accuracy of velocity vector imaging (VVI) in assessing ventricular function in children with single ventricle after cavopulmonary connection.Methods Thirty children with single ventricle after cavopulmonary connection were enrolled in this study,30 agematched normal children were served as control group.The systolic peak velocity,displacement,strain and strain rate in this two groups measured in 6 segments by VVI were compared.dp/dt of single ventricle was estimated by atrioventricular regurgitation using simplified Bernoulli equation.Results Strain and strain rate were significantly lower in all 6 segments in children with single ventricle after cavopulmonary connection compared with values in normal children( P ＜0.05,respectively),strain rate of the basal segment at the rudimentary chamber correlated best with dp/dt (r =0.72,P ＜0.01).Conclusions Segmental ventricular dysfunction was observed in children with single ventricle after cavopulmonary connection,and could be assessed accurately using velocity vector imaging.
RESUMEN
Recently, the annulus cartilaginous-perichondrium made from tragus cartilage-perichondrium were successfully used as grafts in open tympanoplasty and myringoplasty, which showed distinctly better effect than that of fascia temporalis with no drum retract or ossicular chain conglutination and stable hearing. The article retrospectively analyzed long term effect of 150 patients which received tragus cartilage ring with perichondrium as grafts in myringoplasties and mastoidectomy with ? period tympanoplasty, and summarized the superiority and application value of the tragus cartilage ring with perichondrium for tympanoplasty in chronic otitis suppurative media in the period of infection.
