Objective To study the reliability and validity of US School Social Behavior Scale at middle and primary school students in China. Methods Under the guidance of the psychologists,teachers of the primary and middle schools fill on the School Social Behavior Scale and to evaluate the social adaptability of their students. Totally 7516 subjects are interviewed. Results The Scale has pretty split-half reliability and internal consistency because all the split-half reliability coefficient and Cronbach’s ? coefficient of six dimensions and two subscales are above 0.9. Two common factors resulted by factor analysis can explain 93.60% of the total variance. The social adaptability of female,high-grade and good study achievement’s students is better than others. Therefore,the construct validity and discriminant validity are satisfactory. Conclusion The School Social Behavior Scale is applicable for social adaptability research of primary and middle school students in China.

Objective To compare the effects of different opportunity internal fixation in treatment of trau-matic flail chest.Methods Clinical data of 53 cases of patients with traumatic flail chest were selected,in which 28 patients were given internal fixation treatment in 72h after injury (early surgery group),25 patients were given sur-gery after 72h(late surgery group),recovery situation(postoperative ventilation time,chest improve time,ICU stay time,extubation time,hospitalization time)of the two groups were observed,respiratory function changes and compli-cations were compared before and after treatment.Results Postoperative ventilation time,chest X -ray improvement time,ICU stay time,extubation time and hospitalization time of the early operation group were (27.4 ±4.8)h, (88.6 ±7.5)h,(3.8 ±0.7)d,(3.2 ±0.8)d,(13.2 ±5.0)d,which were significantly shorter in the late operation group of (40.7 ±5.2)h,(195.3 ±8.0)h,(5.6 ±1.4)d,(5.2 ±1.3)d,(19.8 ±6.4)d,with significant difference (t =7.389,11.204,3.837,3.916,5.261,all P <0.05 ).After treatment,PaO2 ,PaCO2 ,PaO2 /FiO2 ,RR and HR were all significantly improved (early surgery group t =12.497,6.205,4.136,7.381,14.327,all P <0.05;late sur-gery group t =11.976,5.813,4.649,6.892,14.627,all P <0.05),but the indexes between the two groups were not significantly different(t =0.126,0.013,0.002,0.010,0.215,all P >0.05 ).There was no dead case in the two groups,and the incidence of atelectasis,ARDS and thoracic deformity had no significantly different between two groups (P >0.05 ).Conclusion In treatment of traumatic flail chest,early surgical treatment can rapidly improve the respiratory and circulatory function,it can shorten the postoperative recovery time,and does not increase complica-tions.So,when conditions permit,patients should be given early surgical fixation.

Objective To study the clinical characteristics and outcome of cytomegalovirus(CMV) infection in infants.Methods All data including time of infection,clinical characteristics,laboratory tests and outcome of CMV infections in hospitalized infants were collec-(ted) and analyzed from January,1994 to July,2004.Results In 87 infected infants,congenitally infected newborns,perinatal infection in infants and postnatal infection in infants accounted for 27.6%,62.0%,16.6%,respectively.CMV hepatitis was the most frequent type of disease with the incidence of 41.3%,in which the incidence of splenomegaly was 10.3%.Most of CMV hepatitis infants had a good prognosis with the improved rate 80.5%.Central nervous system abnormality(including abnormal intension of muscle,convulsion,ocular and hearing abnormalities) occurred only in congenital and perinatal infection with the incidence of 20.4%.Generalized infection,the incidence of congenital infection and perinatal infection was 16.7%,1.8%,respectively.It did not occur in postnatal infection.The mortality rate of congenital infection and perinatal infection were 12.5% and 1.85%,respectively.Conclusions CMV infection is the main cause of infant hepatitis and it can also cause neurologic sequelae.The outcome of generalized infection in congenital infection is bad and the mortality rate is high.

Phospholipase D(PLD) is ubiquitous in bacteria,fungi,and mammal.In pathogenic microorganisms,PLD can be pathogenic determinant and play a role in spore generation.In mammalian cells,PLD functions in several signal transduction pathways,such as membrane transportation,mitosis regulation,and actin cytoskeleton regulation.In the process of pathogens invasion host cells,both of the pathogen and host cells’ PLD will be activated and a series of cascade reaction will be generated.During this process,pathogen’s PLD can regulate the polymerization and reorganization of its own actin filaments and induce the polymerization or reorganization of the host cell actin filaments near the foci,thus to promote the phagocytosis of the pathogen by host cell.Investigating the role of PLD activation in the infection will be significance for further understanding the molecular mechanism of pathogen-host cell interaction.

OBJECTIVETo investigate the value of MRI follow-up in pediatric patients with spinal tuberculosis.

METHODSFrom February 2004 to April 2013, MRI imaging data in 21 children with spinal tuberculosis by pathologically and clinically proven were retrospectively analysed. There were 11 males and 10 males, with an average age of 9.4 years old ranging from 2 to 14 years old. Eighteen patients were received conservative treatment, 3 patients were treated by surgical operation. The course of disease ranged from 2 months to 3 years. All cases underwent two or more MRI examinations for follow-up. MRI findings of the first and second examination were comparatively analyzed,including signal changes of vertebral body and intervertebral, paraspinal abscess and the change of kyphosis angle.

RESULTSIn the 21 cases with tuberculosis, 85 vertebral bodies were affected in total, including 10.6%(9/85), 49.4%(42/85) and 40%(34/85) vertebral bodies separately in the cervical,thoracic, lumbosacral spine. Follow-up MRI showed vertebral body shape and signal had no obvious change during or after treatment, 15 cases with vertebral bodies changed flat or cuneate, 10 cases with disc involvement,and intervertebral space became narrowing at different level. Among 13 patients with kyphosis angle greater than 0°, 7 were located on thoracic, 2, 3, 1 were on thoracolumbar, lumbar and cervical spine, respectively. Among 18 cases with conservative treatment,kyphosis angle were 0° on the first and the follow up MRI of 8 patients. One case of mild (<10°) kyphosis,follow-up MRI during therapy showed the angle slightly increased; 5 cases with moderate (10° to 30°), follow-up MRI during therapy showed no obvious change; 4 cases with severe (>30°), follow-up MRI during and after therapy showed kyphosis increased in varying degrees.

CONCLUSIONFollow-up MRI can make a big difference in the spinal tuberculosis of children; it can clearly show the change of the vertebral body and intervertebral space, paraspinal abscess and the kyphosis angle after the treatment,which can provide reference for clinical treatment and estimating prognosis.

OBJECTIVETo analyze and summarize the characteristics and treatment of acute spinal cord decompression sickness. To explore the factors that influence the treatment effect.

METHODS77 cases of acute spinal cord decompression sickness patients should be divided into 4 groups according to the pressurized treatment and drug treatment options. They were group I, group II, group III and group IV. At the same time they were get hyperbaric oxygen therapy and other treatment. The evaluation index, were Frankel function classification and paraplegia index. There were 17 factors that affected the treatment effect.

RESULTSThe rate of early cure was 57.14% (44/77). The rate of late cure was 74.03% (57/77). Their difference was statistically significant (P<0.05). In 3 months and 1 year the cure rate of group IV and group B were the highest. But there was no difference between them(P>0.05). They were higher than group ii and group I (P<0.05). The Frankel function classification in 3months and 1 year in each group was higher than before treatment (P<0.05). The paraplegia index in 3 months and 1 year in each group was lower than before treatment (P<0.05). In 3 months and 1 year the Frankel function classification was increased gradually and the paraplegia index was decreased gradually in group I , group II, group III (P<0.05). In group IV and group III the Frankel function and the paraplegia index had not significant difference (P>0.05). Among the 17 factors that affect the treatment effect there are 9 factors that affect the proportion of the large.

CONCLUSIONSThe first choice of treatment method for the patients with acute spinal cord decompression sickness would be group III. Drug therapy was also imporpant. At the same time the hyperbaric oxygen therapy and other treatments were taken. Although the cure rate was not high in this article. But most of the cure is within 3 months. Within 1 year.the cure rate still could be improved. 9 factors that affect the efficacy of acute spinal cord decompression sickness was more noteworthy.
