This review summarized the researches about physical activity levels, measurement methods, influencing factors and interventions for children and adolescents with intellectual disability. The physical activity levels of children and adolescents with intellectual disability were low, and their health status was not optimistic. The joint efforts of individuals, families and the society were needed to improve their levels of physical activity. The effectiveness of existing physical activity intervention methods should be further discussed. Therefore, focusing on the health demands of children and adolescents with intellectual disability, more researches are needed about in-depth analysis of the dose-effect relationship between physical activity and health indicators, and exploring of effective intervention for physical activity in the future.

Hemispheric asymmetry is a fundamental organizing principle of the human brain. Answering the genetic effects of the asymmetry is a prerequisite for elucidating developmental mechanisms of brain asymmetries. Multi-modal magnetic resonance imaging (MRI) has provided an important tool for comprehensively interpreting human brain asymmetry and its genetic mechanism. By combining MRI data, individual differences in brain structural asymmetry have been investigated with quantitative genetic brain mapping using gene-heritability. Twins provide a useful natural model for studying the effects of genetics and environment on the brain. Studies based on MRI have found that the asymmetry of human brain structure has a genetic basis. From the perspective of quantitative genetic analysis, this article reviews recent findings on the genetic effects of asymmetry and genetic covariance between hemispheres from three aspects: the asymmetry of heritability, the heritability of asymmetry and the genetic correlation. At last, the article shows the limitations and future research directions in this field. The purpose of this systematic review is to quickly guide researchers to understand the origins and genetic mechanism of interhemispheric differences, and provide a genetic basis for further understanding and exploring individual differences in laterized cognitive behavior.

Objective     To analyze the clinical efficacy and safety of endostar or carboplatin combined with endostar intracavitary perfusion in the treatment of malignant serous cavity effusion. Methods     We retrospectively reviewed the clinical data of 78 cancer patients with malignant serous cavity effusion who received paracentesis and intracavitary endostar, or carboplatin combined with endostar in Shengjing Hospital of China Medical University between November 2011 and November 2016. There were 42 males and 36 females at a median age of 62 years ranging from 17 to 78 years. According to treatment methods, 78 patients were divided into two groups, in which 33 patients received intracavitary endostar combined with carboplatin (a combination group, 15 males and 18 females at a median age of 56 years ranging from 17 to 66 years), and 45 patients received intracavitary endostar (an endostar group, 27 males and 18 females at a median age of 63 years ranging from 38 to 78 years). The efficacy and safety of two methods were analyzed and compared. Results     The response rate in the combination group was 75.8%, which was higher than that in the endostar group (60.0%, P=0.035). In quality of life improvement, there was no statistical difference between the two groups (P=0.113). The incidence of fatigue, myelosuppression and gastrointestinal reactions in the endostar group was significantly lower than that of the combination group (P=0.006, 0.000 and 0.017, respectively). Analysis of long-term efficacy revealed that the median time to progress (TTP) in the combination group and endostar group was 171 days and 143 days, respectively (P=0.030). Conclusion     Intracavitary infusion of endostar alone, or carboplatin combined with  endostar is effective and tolerable for controlling malignant serous cavity effusion. But for the patients with poor physical state who can not tolerant platinum perfusion, intracavitary infusion of endostar alone can be adopted to control malignant serous cavity effusion.

Accurate segmentation of ground glass nodule (GGN) is important in clinical. But it is a tough work to segment the GGN, as the GGN in the computed tomography images show blur boundary, irregular shape, and uneven intensity. This paper aims to segment GGN by proposing a fully convolutional residual network, i.e., residual network based on atrous spatial pyramid pooling structure and attention mechanism (ResAANet). The network uses atrous spatial pyramid pooling (ASPP) structure to expand the feature map receptive field and extract more sufficient features, and utilizes attention mechanism, residual connection, long skip connection to fully retain sensitive features, which is extracted by the convolutional layer. First, we employ 565 GGN provided by Shanghai Chest Hospital to train and validate ResAANet, so as to obtain a stable model. Then, two groups of data selected from clinical examinations (84 GGN) and lung image database consortium (LIDC) dataset (145 GGN) were employed to validate and evaluate the performance of the proposed method. Finally, we apply the best threshold method to remove false positive regions and obtain optimized results. The average dice similarity coefficient (DSC) of the proposed algorithm on the clinical dataset and LIDC dataset reached 83.46%, 83.26% respectively, the average Jaccard index (IoU) reached 72.39%, 71.56% respectively, and the speed of segmentation reached 0.1 seconds per image. Comparing with other reported methods, our new method could segment GGN accurately, quickly and robustly. It could provide doctors with important information such as nodule size or density, which assist doctors in subsequent diagnosis and treatment.
