Objective To evaluate the related risk factors in preterm infants with cerebral injury. Methods A total of 268 cases whose gestational age less than 36 weeks had cranial ultrasound scans between 0 to 7 days after birth from January 1, 2006 to October 31,2007, and their clinical data were reviewed. Results One hundred and thirty patients (48.5 %) were diagnosed cerebral injury, total incidence of intraventricular haemorrhge and periventricular leukomalacia were 43.3% (116/268) and 14.3% (38/268) respectively. The incidence of cerebral injury was correlated with low birth weight, prematurity, asphyxia, respiratory distress syndrome, apnea, respiratory failure, pulmonary haemorrhge, anemia, hypotension, hypoglycemia, infection, premature rupture of membrane, low gestaional age at birth and ventilation. Conclusion The incidence of preterm brain injury are related to many factors. Risk factors of cerebral injury should be prevented in clinical practice and cranial ultrasound scans are required for early diagnosis of preterm cerebral injury.

Along with the increasing medical image data,it is imperative to set up an effective system about medical image retrieval.Essentially,the image classification is crucial for medical image retrieval.As a distribution pattern of image gray scale,texture is an important character.Wavelet multi-scale decomposition is essentially multi-channel filtering and its multi-resolution analysis structure is identical with human visual system.So the extraction of texture feature under different resolutions after multi-band wavelets transform is of great benefit to image recognition and image retrieval.Consequently,this paper designs an image classification method based on eight-band wavelet.This method solves the key technology in the medical image retrieval,and it gains very high classification rate.

Objective To investigate the effect of mental diathesis training on recruits' psychological health.Methods A total of 200 recruits were divided into intervention group and control group with 100 recruits in each group.Those in intervention group were trained by Mental Diathesis Training for 6 weeks,and the recruits in control group were not.SCL-90 and Coping styles scale were employed to evaluate the mental health before and after training.Results Except phobia and psychoticism,other factor-scores of SCL-90 of the recruits in intervention gsoup were decreased significantly after the training.Except somatization,no significant difference was found in other factor-scores of SCL-90 of the recruits in control group after the training.Except somatization,phobia and psychoticism,other factor-scores of SCL-90 of recruits in intervention group were significantly higher than that of the recruits in control group(P

Purpose Blast lung injury is severe, and is the main causes of death in explosion. This paper aims to explore the imaging features of blast lung injury, and to provide reference for clinical diagnosis and care. Materials and Methods The clinical data of 37 patients with primary blast lung injury stricken in the 8.2 Kunshan explosion in 2014 were retrospectively studied, with regard to the degree of burn, area, auxiliary emergency treatment and medical history. The imaging manifestations of X-ray and/or CT were also analyzed. Results ① The X-ray and/or CT findings of chest showed that 6 cases (16.2%) presented no obvious abnormality of lung parenchyma, 14 cases (37.8%) manifested increase of lung markings and spot-like clouding opacity, 6 cases (16.2%) presented ground glass opacity, 7 cases (18.9%) manifested patchy shadow, 4 cases (10.8%) showed diffuse consolidation. 6 cases (16.2%) with pleural effusion, 6 cases (16.2%) complicated with pneumothorax and hydropneumothorax, 4 cases (10.8%) with enlarged podoid and pericardial effusion, 2 cases (5.4%) with mediastinal hematoma, 9 cases (24.3%) with rib fracture. The positive rate of X-ray film inspection was 72.2% (13/18), yet that of CT reached 92.9% (13/14). ② Five patients who had not been seen obvious abnormal in emergency lung examination appeared mottling shadows or flake fuzzy shadows in the examination on the second day; 9 cases with aggravated symptoms and infection signs displayed relieved signs, expanded or changed primary lesions. Conclusion Imaging examination is an important tool in the diagnosis of primary blast lung injury. CT is superior to X-ray film on the detection of lesions; therefore, CT examination on chest should be carried out as soon as possible if conditions are allowed.
