Plastic bronchitis is a rare condition characterized by bronchial casts, that may result in respiratory failure, suffocation and even death.Therefore, early diagnosis and treatment are of great significance.This article summarizes the imaging characteristics of plastic bronchitis, in order to further improve the understanding of the disease among pediatricians, radiologists, and emergency physicians.

OBJECTIVETo provide quantitative foundation for the diagnosis of atlanto-axial rotatory subluxation by analyzing the various imaging features of normal atlanto-axial joints in neutral position and rotary functional position on the MSCT images.

METHODSForty-one normal volunteers were examined by CT on the atlanto-axial joint in neutral position and rotary functional position. By the observation and measurement of atlanto-dental interval (ADI), lateral atlanta-dental space (LADS), VBLADS and rotating angle of atlas on dentate (RAAD), the imaging manifestations and anatomical characteristics were analyzed and compared. In order to compare VBLADS and RAAD and make a correlation analysis between different age groups, 51 normal volunteers were divided into two groups: age younger than 45 years old group and age older than or equal to 45 years old group.

RESULTSThe dens in neutral position deviated in an angle range of (3.22±0.89)°. The articular facets of lateral atlantoaxial joint in rotary functional position had rotatory displacement and the range of the relative rotation angle was (33.85± 2.79)°. Through the correlation analysis of matching data, it could be concluded that there was no correlation between atlantoaxial relative rotation angle and VBLADS within a certain range. There were statistically differences of atlantoaxial relative rotation angle in rotary functional position between two groups.

CONCLUSIONMSCT imaging in rotary functional position can clearly show the anatomical structure and rotation function of a normal atlanto-axial joint, so as to provide a theoretical basis for the diagnosis of atlanto axial rotatory subluxation.

Objective To study the effect of Sopfrology childbirth method training,Kegel training and Lamaze respiratory training (SLK training) on depression and sexual life of perinatal pregnant woman..Methods The women in 24 weeks of pregnancy who came to the clinic to receive the pregancy test were divided into study group(n=232) and control group(n=126) according whether they voluntered to participate the study.All the women in two group were subjected to regular prenatal care and the women in study group received SLK training additionally.The depression,pelvic floor muscle tension and female sexual function index were evaluated by Self Rating Depression Scale(SDS),the Pelvic Floor Muscle Examination Grading Standards and the Female Sexual Function Inventory (FSFI) respectively.Results 6 months after delivery,the incidence of depression,SDS score,pelvic floor muscle tension score and live index standard rate in study group and the control group respectivelywere(10.3％ vs 18.3％),((43.6±5.1) vs(45.3±6.3)),((3.36±0.33) vs(2.46±0 89)),(81.5％ vs 65.9％),and the differences were statistically significant(P＜0.05).Conclusion SLK training program for perinatal women has the effects of preventing,treating prenatal depression and postpartum depression,improves pregnancy index and the quality of sexual life,worthy of further study.

Objective To establish appropriate correction models of serum marker α -fetoprotein (AFP) multiple of the median (MOM) for prenatal screening on patients with neural tube defect (NTD) at the second trimester to replace the foreign data currendy used in Beijing with a higher sensitivity.Methods A sample of 5815 mid-gestation pregnant women with normal pregnancy outcome were selected including 5557 cases of age ＜ 35 years and 258 cases of age ≥35 years.The regression relationship between AFP median and gestational age was builded by exponential model and the regression relationship between MOM and weight was builded by power model in age ＜ 35 years.The regression relationship between AFP median and gestational age was builded by S model and the regression relation ship between MOM and weight was builded by quadratic model in age ≥35 years.The normal reference values in two age sections were estimated approximately by percentiles method.Results Corrected AFP MOM values with mean value (age ＜ 35 years:1.001; age ≥35 years:1.113) and median value (age ＜ 35 years:0.934;age ≥35 years:0.990) obtained by regression analysis were more close to 1.00 than the data from the software[mean value(age ＜ 35 years:1.164; age ≥35 years:1.254) and median value (age ＜35 years:1.093; age ≥35 years:1.149)].There were significant differences (age ＜35 years:t =65.120,P =0.000;age ≥35 years:t =9.812,P =0.000).Conclusion Correction model for maternal serum marker is more applicable for Beijing population at the second-trimester prenatal screening.

Objective To elucidate the etiology feature of viral infection in hospitalized children with acute lower respiratory infection. Methods A total of 5 480 children with acute lower respiratory tract infection, hospitalized from September 2007 to September 2009, were studied. Nasopharyngeal aspirates were screened for 8 types of viruses by direct immunofluorescence (DIF) assay. Results At least one type of viral pathogen was detected in 2 710 out of 5 480 patients and the overall positive rate was 49.5%. The most common virus was RSV (51.1%), followed by hMPV (18.9%), PIVⅢ (12.5%), ADV (7.1%), IFA (4.7%), IFB (2.9%), PIV Ⅰ (1.5%) and PIV Ⅱ (1.2%). The positive rate was highest in children under 6 months (43.5%). The seasonal change of RSV, hMPV was more obvious. The peak of RSV, hMPV appeared in the winter and the spring. The prevalence of viral infection in children with pneumonia, bronchitis, asthmatic bronchitis, non asthmatic bronchitis and asthma were 47.4%、63.6%、 50.5%、 30.1% and 43.5% respectively. Conclusions Viruses are the main cause of lower respiratory tract infections in children, especially in infants and young children. RSV and hMPV were the most common viruses in these years.

Objective To investigate the risk factors for postoperative nausea and vomiting (PONV) in spinal anesthesia patients.Methods A total of 841 patients received spinal anesthesia were visited after operation.Data were analyzed using univariate analysis and multivariate Logistic regression to identify risk factors related to PONV.Results PONV occurred in 94 patients (11.2％,94/841).Univariate analysis showed that PONV was unrelated with gender,age,ASA classification,anesthesia mode (P ＞ 0.05),related with operation department (P =0.026),body mass index (P =0.020),education level (P =0.000),history of previous surgery anesthesia (P =0.005),history of PONV (P =0.000),history of kinesia (P =0.002),smoke (P =0.019),intraoperative using of tramadol (P =0.018).Multivariate analysis showed that operation department (OR =4.039,95％ CI 1.331-12.259,P=0.048),education level (OR =3.504,95％ CI 1486-8.260,P=0.015),history of PONV (OR =5.113,95％ CI 1.790-14.606,P =0.002),intraoperative using of tramadol (OR =5.316,95％ CI 1.091-25.908,P =0.039) were identified as independent risk factors for PONV.Conclusions The independent factors associated with PONV following spinal anesthesia include operation department,education level,history of PONV,intraoperative using of tramadol.Identifying patients who are at high risk for PONV will enable the formation of more timely management project.

Two parental strains BY-14 and BY-6,with high leavening ability in lean and sweet dough respectively,were selected.Through spore production and separation,two haploids with opposition types were selected for cross-breeding.At last one hybridization strain was obtained,with good fermentation ability as BY-14 in lean dough and better than BY-6 by 25%in sweet dough.

AIM: To investigate the clinical effects of intravitreal Bevacizumab for 26 cases with retinopathy of prematurity (ROP) in Zone Ⅰ.
METHODS:A retrospective study. Totally 26 ROP infants between September 2013 and October 2014 diagnosed as high - risk ROP in Zone Ⅰ had been treated with intravitreal bevacizumab. They were divided into three groups, pre - threshold ROP, threshold ROP and acute posterior ROP ( APROP ). Postoperative effects were compared.
RESULTS:There were 26 infants (52 eyes) diagnosed as ROP in Zone Ⅰ, including 3 infants( 6 eyes) with pre -threshold ROP, 15 infants (30 eyes) with threshold ROP and 8 infants (16 eyes) with APROP. The first operation recovery rate of three groups respectively were 100% (6 /6), 60% ( 18 / 30 ) and 75% ( 12 / 16 ), which were not significantly different (P>0. 05).
CONCLUSION:Intravitreal bevacizumab for ROP in ZoneⅠ seems effective and has some advantages over conventional laser treatment, which could be first line treatment for high-risk ROP in Zone Ⅰ.
