ABSTRACT
Objective@#To examine the status of bullying behaviors and psychological resilience of primary school students and the relationship between the two, and to provide references for related interventions.@*Methods@#Olweus bullying questionnaire and adolescent psychological resilience scale were used to select students in grades 4-6 for questionnaire survey.@*Results@#Primary school students who were bullied, bullied others, double-involved and uninvolved accounted 33.3%, 48.7%, 15.3%, and 2.7%. There were statistically significant differences in bullying in different dimensions of different genders, grades, and previous suicidal thoughts (P<0.05); there were statistically significant differences in the bullied status of only children, divorced parents, and different caregivers (t/F=3.64，2.65，6.62，P<0.05); The status of bullying behavior of students in the class was better than that of ordinary students (t=-2.18, P<0.05); senior students have a higher level of positive cognition (F=8.71, P<0.05); mental toughness of urban students better than rural areas (t=-2.20, P<0.05); students with divorced parents had poor levels of emotional control, family support, and psychological toughness (t=-4.60，-3.92，-3.44，P<0.05); class cadres focused on focus, positive cognition, family support, interpersonal assistance, and psychological resilience were better than ordinary students (t=5.19，6.43,5.64,4.13，6.58，P<0.05); students with parental care had better levels of target concentration, emotional control, family support, interpersonal assistance, and psychological resilience (t=4.59，8.68，8.76，12.35，13.45，P<0.05); the level of psychological resilience of students was low (t=15.90，P<0.05). Correlation analysis shows that there was a negative correlation between bullying behavior and psychological resilience of all pupils (P<0.01), regression analysis showed that bullying behavior may had a negative prediction of mental resilience (F=128.37, R2=0.12, P<0.01).@*Conclusion@#The current situation of bullying behavior and mental resilience of grade 4-6 students is worrisome, and it is urgent to improve the current situation of bullying and psychological resilience of primary school students.
ABSTRACT
Twenty-five pediatric patients (10 males,15 females) with inherited epidermolysis bullosa,aged 3-16 yr,weighing 11-29 kg,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,underwent lysis and reconstructive surgery of both hands adhesions from July 2015 to April 2017 in our hospital.Ketamine 4-6 mg/kg and atropine 0.01 mg/kg were intramuscularly injected at 20 min before admission to the operating room.Oxygen 2 L/min was inhaled by mask after admission to the operating room.Anesthesia was induced by Ⅳ injection of midazolam 0.08 mg/kg and ketamine 2 mg/kg.Pediatric patients kept spontaneous breathing.Anesthesia was maintained by Ⅳ infusion of propofol 5 mg · kg-1 · min-1 and remifentanil 0.05-0.08 μg · kg 1 · min-1.Mepitel was used to protect skin during surgery,and sodium potassium magnesium calcium and glucose injection was intravenously infused to replace the physiological requirement,blood loss and continued loss.Anesthesia time was (130±43) min,surgery time (107±42) min,the amount of intraoperative fluid infused (352± 120) ml,blood loss (29± 10) ml and emergence time (15±6) min.Intraoperative respiratory depression was found in 5 cases (20％);postoperative new bullae occured in 3 eases,and among the 3 cases,one developed on the back and the other two on the buttocks.No cardiovascular events occurred during and after surgery in this study.
ABSTRACT
Objective To evaluate the relative quantities of flt-1, KDR, endostatin mRNA in tissue specimens of human hemangioma and great saphfenous vein with the modified reverse transcriptase-polymerase chain reaction (RT-PCR). Methods Total RNA from human specimens by Trizol was reverse-transcribed and amplified by PCR in 4 deffirent tubes containing one of the primer pairs such as flt-1, KDR, endostatin or ?-actin. The target genes and beta-actin PCR products were about 200 bp in length. The ratio of the yield of the target gene PCR product to the beta-actin PCR product could be calculated after 35 cycles of amplification.Results These ratios were correlated positively ( P=0.014,P=0.019) in two groups, but no relationship in endostatine level was observed (P=0.436).Conclusions VEGFR may play a very important role in the pathogenesis of the congenital hemangioma in children. But the endostatin may take little effect on it.
