Children's tumors have a great impact on society. Pediatric tumors can be identified and eradicated early, only with a full participation of children's caregivers. This paper discusses the four level prevention and control strategy of the children's malignant tumor, with an emphasis on the necessity and the specific methods of the mother's participation in diagnosis of the malignant tumor of children. We suggest a training of mothers by the most grass-root paediatric medical personnel.

Since the implementation of the "Grain for Green Program" by Chinese government in 1999, the vegetation coverage of the Loess Plateau has increased significantly, which has effectively prevented the soil erosion in this region. The latest research shows that the vegetation net primary productivity (NPP) in the Loess Plateau has already approached the threshold of the regional water resource carrying capacity, thus a further expansion of the vegetation area will inevitably aggravate the situation of water shortage in this region. To further consolidate the achievements of "Grain for Green Program", the future vegetation construction in the Loess Plateau should change from expanding the area to improving the quality.

The working models of the Materials Genomic Engineering can be roughly classified into those of the experiment-driven, the computation-driven and the data-driven. The last kind of model is consistent with the fourth paradigm of scientific approach of a fundamental change from "trial and error" to "data-intensive". Such a paradigm shift allows one to acquire the composition-structureprocess-performance relationship, as the basis for the rational design of materials, in a faster, cheaper and more accurate way. It represents the core concept and the future direction of the MGI. In this data-centric scientific era, the ability to quickly obtain a large amount of materials data becomes essential. Thus, the "data foundries"-the centralized materials data generation facilities based on high-throughput experiments and high-throughput computations are the key infrastructures for meeting the future data needs. It is contemplated that the data and the artificial intelligence will become the foundation for building the materials science of the future.

The State Oceanic Administration(SOA) has four private networks, the national oceanic administration network, the state oceanic administration network, the national marine non-real-time service network and the national marine real-time service network. The four private networks operate independently and provide support for different ocean professional tasks. The SOA promotes the information integration, first with the network integration as the basic project. The integrated marine information communication network is the foundation for the integration of the following offshore network and the sea-related ministry network, the data resources and the business systems. This paper reviews the existing marine service private network and the integrated marine information communication network systematically and analyzes the shortcomings of the offshore data acquisition in the existing network in view of the characteristics of the multi-channel acquisition of the marine data. With consideration of the needs of the offshore data acquisition in the ocean and the existing wireless network access mode, the idea of the overall construction planning of the marine wireless network is put forward.

The marine information engineering has gradually turned from conceptual and theoretical studies to actual construction and application services. Taking the example of Digital Ocean Engineering of China, this paper analyzes the current situations and foundations of China's marine informatization establishment by introducing the establishment process and achievements of Digital Ocean. By discovering the gap between America, Japan and other developing countries on data acquisition, processing and applications, this paper offers references on development tendency for marine informatization establishment of China.

Sorghum-sudangrass hybrids are annual gramineous forage crops with intergrated excellent parental traits. Their heterosis is particularly prominent, but the molecular mechanism of the heterosis is not yet very clear. To reveal the molecular mechanism, the mature embryos of sorghum-sudangrass hybrids and their parents are analyzed by the Label free mass spectrometry and the bioinformatics methods based on proteomics in this study. 124 differentially expressed proteins are identified, among which 48 are additive accumulation proteins, accounting for 38.71% of the total proteins. 19 and 29 of them are up-regulated proteins and down-regulated proteins, respectively. 76 of them are non-additive accumulation proteins, accounting for 61.29% of the total proteins. 29 proteins are of the above-high-parent expression, with the greatest proportion among the non-additive accumulation expression patterns. Followed by the high-parent expression patterns(18 proteins), the low-parent expression patterns (14 proteins), the below-low-parent expression patterns(10 proteins). Besides, there are 5 proteins which do not belong to the above four kinds of protein expression patterns. Therefore, non-additive proteins play especially dominant roles in the heterosis of the mature embryo of sorghum-sudangrass hybrids. Additive and non-additive accumulation proteins cover multiple functional groups, which involve the stress response, the carbohydrate metabolism, the transcriptional regulation, the development regulation, the signal transduction, the protein metabolism and others.
