Objective To evaluate the diagnostic rate and treatment effect of close renal trauma.Methods The clinical data of 129 cases of close renal trauma were analyzed retrospectively. Results Lumbago or bellyache occurred in 109 cases,hematuria 113 cases,coexistent injuries of other organs 81 cases. 129 cases were examined by type B-ultrasonography, 102 cases by CT scan open operation on 17 cases and others were treated non-operatively. 118 cases have been followed up for 3 months to 56 months with normal urine routine and IVU.Conclusions Usually urine inspection and B-ultrasonography were simple,instant reliable and safe. The accurate diagnosis rate was higher with CT scanning,CT scan was helpful in detecting the degree of renal injury and any coexistent injuries,and to estimate the treatment effect. Laparotomy should undertaken for the case of severe injury or with coexistent injuries in rime.

Objective:To explore the factors influencing the pulmonary function of persons with mild to moderate adolescent idiopathic scoliosis (AIS).Methods:Forty-four persons with AIS were tested for their pulmonary ventilation functioning. The indicators were the percentage of forced vital capacity (FVC%), the percentage of forced expiratory volume in the first second (FEV1%) and the percentage of maximum chase volume (MVV%). Data including age, gender, course of disease, dancing habits, exercise habits, body mass index (BMI), Cobb angle, rotation angle, diaphragm thickness, and diaphragm excursion (DE) were also collected. Linear regressions were evaluated to analyze the factors best predicting pulmonary functioning. Spearman correlation coefficients were computed to quantify the correlation between respiratory muscle functioning and pulmonary functioning.Results:The univariate analysis showed that dancing and DE independently influence FVC%, FEV1%, and MVV%. DE was the only independent factor significantly predicting pulmonary functioning for mild to moderate AIS patients. DE was also significantly positively correlated with average FVC%, FEV1% and MVV%.Conclusions:Respiratory training aimed at enhancing DE is necessary to improve the pulmonary ventilation of persons with AIS.

The organization of the brain follows a topological hierarchy that changes dynamically during development. However, it remains unknown whether and how cognitive training administered over multiple years during development can modify this hierarchical topology. By measuring the brain and behavior of school children who had carried out abacus-based mental calculation (AMC) training for five years (starting from 7 years to 12 years old) in pre-training and post-training, we revealed the reshaping effect of long-term AMC intervention during development on the brain hierarchical topology. We observed the development-induced emergence of the default network, AMC training-promoted shifting, and regional changes in cortical gradients. Moreover, the training-induced gradient changes were located in visual and somatomotor areas in association with the visuospatial/motor-imagery strategy. We found that gradient-based features can predict the math ability within groups. Our findings provide novel insights into the dynamic nature of network recruitment impacted by long-term cognitive training during development.
