ABSTRACT
Objective@#To explore the relationship between parental control and aggressive behavior of middle school students.@*Methods@#Random cluster sampling was used to select 1 046 students.Information was collected through the Chinese version of Parental Control Questionnaire and Buss ＆ Perry Aggression Questionnaire.@*Results@#The score on anger were high among female students and the total score were high among male students(t=6.28,2.56,P<0.01).Multiple comparison showed. the grade two junior middle school students’aggression level is significantly higher than grade three junior middle school students and grade one, two high school students(t=3.22,4.07,3.01,P<0.05). There were significant gender differences in parental control,father’s behavior control and father’s psychological control(P<0.05).Parental control shows a significant grade difference,multiple comparison showed, parental control among junior middle school students is significantly higher than that among high school students(t=3.22, 4.07, 3.01, P<0.05).Parental control and aggressiveness of the students were significantly positively correlated(r=0.16,0.29).There was a significant positive correlation between the psychological control of the parents and the aggressiveness of the boys(r=0.26,0.23).The behavior control and psychological control of the parents were positively correlated with the aggressiveness of the girls(r=0.09,0.13,0.29,0.35)(P<0.05).The Logistic regression analysis showed,father’s psychological control(OR=0.50,95%CI=0.21-0.79) and mother’s psychological control(OR=0.32,95%CI=0.02-0.62) showed significant positive association with aggression of the boys.Mother’s psychological control(OR=0.55,95%CI=0.23-0.87)and parents’ control(OR=0.17,95%CI=0.01-0.33) were positively associated with aggression of the girls(P<0.05).@*Conclusion@#Effective intervention of parental control might help prevent and control aggressive behavior of middle school students.
ABSTRACT
Objective To study the clinical value of electronic bronchoscope in diagnosis and treatment of recurrent dyspnea in neonates.Method From October 2014 to October 2017,the clinical data of recurrent dyspnea receiving electronic bronchoscopy examination and treatment in the neonatal intensive care unit of our hospital were retrospectively selected.Their clinical characteristics and treatment effects were summarized and analyzed.Result A total of 171 infants of neonatal recurrent respiratory infections were examined using electronic bronchoscope.The top four causes included endo－tracheo－bronchitis in 78 cases (45.6%), laryngomalacia, and tracheobronchomalacia in 22 cases (12.9%), airway stenosis in 14 cases (8.2%) and esophagotracheal fistula in 12 cases ( 7.0%).The complications of intraoperative and postoperative included decline of percutaneous oxygen saturation and /or heart rate (20.5%, 35/171), mucosal bleeding (12.3%, 21/171 ), and fever after bronchoalveolar lavage.Electronic bronchoscopy examination confirmed all the 171 neonates′diagnosis and some of them recovered after corresponding treatment.78 cases of infants with endo－tracheobronchitis were all cured.22 cases of laryngomalacia and tracheobronchomalacia and nine patients with airway stenosis improved and were discharged after treatment . One patient with subglottic stenosis received bronchoscopic holmium laser ablation therapy and the airway significantly expanded.No re－stenosis was found during follow－up.Conclusion Electronic bronchoscopy is an important method to determine the cause of recurrent dyspnea in newborns , and it′safe,reliable and can play a therapeutic role in some neonates.
ABSTRACT
Purpose To investigate the relationship between fetal lateral ventricle dilatation complicated with malformation and chromosome abnormalities,so as to provide reference for clinical consultation.Materials and Methods The ultrasound images,karyotype analysis and high resolution microarray comparative genomic hybridization (aCGH) results of 150 fetuses with lateral ventricular dilatation diagnosed by ultrasound were analyzed retrospectively.Results Among 150 lateral ventricular dilatation fetuses,81 cases were isolated lateral ventricle dilatation,30 cases were found complicated with fetal ultrasound soft index,22 cases with other CNS malformations and 17 cases with other malformations.Karyotype analysis of the above 4 groups showed 13 cases of abnormal karyotypes and 15 cases ofaCGH abnormalities.There was statistical significant difference (P＜0.05) in each group of abnormal chromosome and aCGH detection rate,in which the softer marker's group had a significantly higher rate than the isolated ventriculomegaly's group in abnormal chromosome and aCGH (P＜0.05).There was no statistical significant difference in any other groups (P＞0.05).Conclusion Fetal systems should be carefully examined when prenatal ultrasound reveals lateral ventricular dilatation.The probability of abnormal chromosome increases significantly when complicated with fetal ultrasound soft index or other structural abnormalities.Chromosomal abnormalities need to be excluded and regular ultrasound follow-up is necessary in fetuses with isolated lateral ventricles.
ABSTRACT
Objective To explore ultrasonographic characteristics and prognosis of cesarean scar pregnancy in the ultrasound.Methods To conducted a retrospective study of 8 cases of diagnoses of cesarean scar pregnancy in ultrasound in our hospital from January 2013 to August 2015.All cases had ultrasonographic examinations regularly during the pregnancy and were confirmed placenta increta by cesarean section or prenatal MRI (6 cases).The imaging characteristics of 8 cases of pregnant women in early pregnancy by transvaginal ultrasound,and the positions of gestational sac and chorion frondosum were observed.Ultrasonic follow-up results,numbers of cesarean delivery,final diagnosis,and pregnancy outcome were analyzed.Results Eight cases of patients were diagnosed cesarean scar pregnancy,and all of ceses were diagnosed placenta increta by ultrasound from 11 weeks to 24 weeks of gestation.It was found that the positions of chorion frondosum were located in the lower edge of gestational sac in Two-dimensional ultrasound and the chorion frondosum was covered in cesarean section scar.The echoes of proliferous chorion frondosum were stronger than the rest of chorion leve and decidua reflexa,and the thickness of proliferous chorion frondosum were thicker than the rest of chorion leve and decidua reflexa.In the follow-up ultrasound of 8 cases in the second trimester,the original position of chorion frondosum which covered and the position of placenta were roughly similar.The position of placenta did not move up with the gestational weeks,in addition,appeared as placenta previa and covered in cesarean section scar.Five patients had strong childbearing willing of continue to conceive,one case of which needed hysterectomy,four of which underwent cesarean section delivery with alive births after using bilateral iliac arteries balloon occlusion.The rest 3 cases underwent induction of labor after using bilateral iliac arteries balloon cclusion.Conclusions Cesarean scar pregnancy in first pregnancy may be develop as placenta accreta in second and third trimester pregnancy.If chorion frondosum was observed to cover cesarean section scar by ultrasound in early pregnancy,scar pregnancy diagnosis was established.Pregnant women who have strong willing to continue their pregnancy should be pay more attentin to thiers placenta previa and placenta percreta in second and third trimester pregnancy.Close follow-up are needed.
ABSTRACT
Purpose To explore the clinical value of ultrasound in charactering brain anomalies in open spina bifida at 11-13+6 weeks of gestation.Materials and Methods Abdominal and transvaginal ultrasound was performed in 125 cases of normal fetus and 4 cases of confirmed open spina bifida at 11-13+6 weeks of gestation to compare the morphology of intracranial translucency (IT), diencephalon and midbrain.Results Fetal IT was readily recognized in all 125 normal cases, with diencephalons and midbrain showing number 8 shape. In 4 cases of open spina bifida, fetal IT cannot be identified, and the expected 8 shape of diencephalon and midbrain was distorted.Conclusion Fetal brain characteristics including intracranial translucency and the shape of diencephalon and midbrain in 11-13+6 weeks gestation are valuable ultrasound screening indicators for open spina bifida.
ABSTRACT
In the present study ,we aimed to observe the effect of curcumin on TSST-1-induced inflammatory cytokines in splenocytes of mouse and provide evidence for the further study on the effect of curcumin on inflammatory shock .Lactate de-hydrogenase (LDH) release assay was used to determine cytotoxicity of different doses of TSST-1 and curcumin .Inflammatory cytokines were determined by ELISA and flow cytometry .The doses of TSST-1 and curcumin we used in the present study did not cause significant cytotoxicity .TSST-1 induced higher level of IFN-γand IL-2 production but relatively lower level of TNF-α.The production of IL-1β,IL-6 and IL-12 was undetectable .TSST-1 induced Th1 cytokines (IFN-γand IL-2) were not IL-12-dependent which was different from LPS-induced IFN-γ.Curcumin significantly reduced IFN-γand TNF-αproduction at the concentration of 15 umol/L (P0 .05) .It’s suggested that curcumin could significantly inhibit the production of IFN-γand TNF-αby splenocytes induced by TSST-1 ,but could not affect the prolifera-tion of T cells .
