Objective To explore the application of high-frequency oscillatory ventilation(HFOV)postoperatively after open heart surgery in children with congenital heart disease.Methods From Jun.2007 to Jun.2008,a total of 1 957 cases were operated in pediatric center of Fuwai cardiovascular hospital.Thirteen cases of 1 957 were given HFOV.Among these 13 patients,8 were male and 5 were female;Age was(13.4?15.4)months.The range of weight was 4.2-12.5 kg.Four cases were tetralogy of Fallot,3 cases were transposition of the great arteries(1 case was corrective transposition of the great arteries),2 cases were total anomalous pulmonary venous connection,2 cases were total endocardial cushion defects,2 cases were pulmonary artery atresia,all patients were under cardiopulmonary bypass repaired operation except 1 patient with PAA under Blalock-Taussig procedure.All patients were mechanical ventilated after surgery.Results The duration of switching general mechanical ventilation to HFOV was(15.70?20.33)days and patients continued to be on HFOV about(10.0?7.5)days.In short term,the lung function of ventilation and gas exchange were be improved by HFOV,but the long-term result was not sa-tisfactory due to a high mortality.There were 5 survived(38.4%)in this group.Six cases of the patients succumbed to consolidation of lung.The commonest complication was pneumothorax(7 cases).Conclusions Short term of HFOV in children with congenital heart disease was satisfactory postoperatively.But there was a high mortality.HFOV can be regarded as a transition method for unsatisfactory long-term.

Objective To investigate domestic child abuse within one year before the survey being conducted in Grades 4-6 preliminary school students and explore the relationship between domestic child abuse and mental health problems including prevalence of mental disorders,anxiety,depression as well as children's selfawareness in this sample.Methods Screen Questionnaire of Child Abuse was used to screen all the students participated in the survey.For those students whose screen results were positive,further face to face interview was needed to verify the abuse history.Once a child was identified as abused one,a student without abuse history would be matched by sex and the same age.Both groups with abused history and without abuse history over past year were evaluated by the two child psychiatrists with diagnostic an statistical manual of mental disorder (DSM-Ⅳ) and mental health scales.Results 1500 10-13 year-old children received child abuse screening.23.73% students surveyed over the past year suffered child abuse in the family.The proportion of boys who were victims of domestic child abuse was 30.44% while 17.44% to girls (x2 =5.95,P < 0.01).The proportion of male students who were victims of domestic abuse was two times that of female students.For all participants,14.6% had been suffered one-way abuse,5% for two-way abuse,and 3% for three-way abuse.Prevalence of anxiety disorder in abused students was higher than in non-abused ones (9.26% vs 3.45%,x2 =3.19,P=0.0015).Similarly,the rate of disruptive behavior disorder in abused students was higher than in non-abused ones(18.53%vs 9.22% x2 =3.61,P=0.0001).The total scores of The Screen for Child Anxiety Related Emotional Disorder was higher in abused students group than in non-abused students group while the total scores of Piers-Harris Children's self-concept Scale was lower in abused student group than in non-abused student group.Conclusion Domestic child abuse in 10-13 old-age students is a widespread phenomenon and abuse history over last year is associated with current mental health level.

Objectives To study the age and gender distribution of clinical and non-clinical depressive symptoms in chil-dren, and the potential link between non-clinical and clinical depressive symptoms. Methods 4520 children aged 8-15 years old were screened for mental disorders by Strength and Dififculties Questionnaire (SDQ) and the Development and Well Being Assessment (DAWBA), and further assessed by the Depression Self-Rating Scale for Children (DSSC). Fifty-three children diagnosed as depressive disorder were included in clinical group and 1504 children without depression disorders whose DSSC scores≥14 were included in non-clinical group. The relationship between gender, age and DSSC scores was analyzed. Results Interaction effect on DSSC scores between gender and age was found in clinical group (F=4.40, P=0.049), but not found in non-clinical group (F=1.04, P=0.409). DSSC scores of girls were higher than that of boys in clinical group (t=2.16, P=0.048). There was no statistically signiifcant main effect of gender in non-clinical group (F=0.21, P=0.646). No signiifcant difference in DSSC scores existed among different age groups in clinical group (F=0.82, P=0.573). There was signiifcant main effect of age in non-clinical group (F=1.96, P=0.048). Conclusions There were different age and gender distribution of clinical and non-clinical depressive symptoms in children.

The design space of the high shear wet granulation process was established and validated within the framework of quality by design (QbD). The system of microcrystalline cellulose-de-ioned water was used in this study. The median granule size and bulk density of granules were identified as critical quality attributes. Plackeet-Burmann experimental design was used to screen these factors as follows: dry mixing time, the impeller and chopper speed of dry mixing, water amount, water addition time, wet massing time, the impeller and chopper speed of wet massing and drying time. And the optimization was implemented with the central composite experimental design based on screened critical process parameters. The design space of the high shear wet granulation process was established based on the quadratic polynomial regression model. Since the P-values of both models were less than 0.05 and values of lack of fit were more than 0.1, the relationship between critical quality attributes and critical process parameters could be well described by the two models. The reliability of design space, illustrated by overlay plot, was improved with the addition of 95% confidence interval. For those granules whose process parameters were in the design space, the granule size could be controlled within 250 to 355 μm, and the bulk density could be controlled within a range of 0.4 to 0.6 g x cm(-3). The robustness and flexibility of the high shear wet granulation process have been enhanced via the establishment of the design space based on the QbD concept.

Objective To evaluate the eradication rate and long-term therapeutic effect of a triple therapy consisted of cla-(rithromycin) (CLA), amoxicillin (AMO)and omeperazole on Hp infection,and explore the alternative therapeutic programs and their effects after first therapeutic failure.Methods A total of 92 children with Hp infection were divided into two groups: 70 children were given the triple therapy for one week (CLA group);Twenty-two children were given another triple therapy composed of metronida-(zoole) (MET), AMO and omeperazole for two weeks (MET group).All of the children were followed up for 1-30 months after the therapies ended.Children of the two groups who were therapeutic failure were given retreatment as follows.CLA triple therapy were given for one week to the children who were failure after MET triple therapy;increased doses of CLA with longer treatment course was given to the children who were failure after CLA triple therapy . A tetra therapy consisted of colloidal bismuth subcitrate (CBS), furazolidone (FUR) ,omeperazole and AMO was given to children in whom the retreatment failed.Results The Hp eradication rate of CLA group was 91.4%(64/70),and the Hp eradication rate of MET group was 72.7%(16/22).There was significant difference between eradication rate of the two groups(?~2=5.16 P
