The viscoelastic surfactant (VES) is widely used in reservoir stimulation owing to its unique physical and chemical properties under formation condition. The viscoelastic surfactant micelle structure and characteristics as well as its mechanism were briefly introduced at first. Based on these, two related parts, the VES fracturing fluid and VES self-diverting acid, were detailedly discussed and summarized from all aspects of the theoretical basis, technical progress and field application. Characteristics of VES fracturing fluid like strong carrying capacity, low filtration, high efficiency, qualified fracturing flow back ability, low formation damage were shown. It was easy for VES acid to get deep reparation, break smoothly, and causes less damage and less filtration. Finally, it was  pointed out that the study of viscoelastic surfactants still need to overcome the difficulties and problems, so as to promote the  application of viscoelastic surfactant in the field of oil and gas reservoir production.

DEAD-box RNA helicases (DDX) are a member of RNA helicases superfamily, they utilize energy derived from nucleotide triphosphate (NTP) hydrolysis and function as molecular complexes by interacting with other proteins in cell. DDX are implicated in  remolding ribonucleoprotein complexes, RNA or DNA and in this manner affect the output and poly morphism of RNA. Nowadays, with an increasing number of researches, it has been identified that DDX are playing critical roles in tumorigenesis and tumor progression, their expression levels are related with tumor growth, metastasis and prognosis, besides, DDX are suggested to have both pro and antiproliferative roles in cancer. In this review, the research progress of relationship between DDX functions and neoplasm are reviewed to discuss the mechanism of DDX in tumor initiation, development and the significance of DDX in tumor prognosis and therapeutic.

Based on literature analysis and data from ISI Web of Science database, the status and characteristics of seismic geological research in the world from 1971 to 2015 are investigated. The result shows that the number of international seismic geological science research paper is being kept growing, and the growth is particularly rapid especially since 1990. The seismic geological science research is under the influence of some major earthquake events. In addition, the United States has the highest number and the highest influence papers, the most cooperative center, and takes the dominant position in this field. While the start of China’s seismic geological science research is late, so the influence remains limited, and the power is concentrated in CAS and CEA. Furthermore, the international seismic geological science research field focuses on such aspects as earthquake mechanism, seismogenesis and activity characteristics, earthquake damage prediction, earthquake disasters and risk assessment, seismic prospecting and so on.

To explore the application status of fuzzy mathematics in the field of safety systems engineering and to further enrich the connotation and method system of safety system engineering, firstly, the bibliometric method and content analysis method were used to analyze the literature number of fuzzy mathematics that applied in safety field through the time angle. Then the microdistribution characteristics were analyzed in three aspects: research content, method category and application industry. Finally, prospect of the fuzzy mathematicsconcrete method and application in security field were summarized. The results showed that the research of fuzzy mathematics in safety system engineering was focused on the security problems under the multidimensional factors, human association and variable factors etc. However, due to the incompleteness and confusion of fuzzy mathematics, the application of mathematics in safety System engineering had gradually entered the bottleneck period, so some improvement should be done through the aspects of fuzzy mathematics method system and evaluation index system construction.

An evaluation index regarding regional innovation network structure feature and Theil weighted TOPSIS evaluation model are proposed to analyze the regional innovation network structure feature of 30 provinces, municipalities and autonomous regions (exclude Tibet) in China. The evaluation results demonstrate that there are significant diversities between regions. Beijing, Shanghai and Guangdong are the top three regions. Ningxia, Inner Mongolia and Guizhou are the last three ones. According to the evaluation results, the regional innovation network development level of 30 regions are classified into four types by using cluster analysis. The regional development policy corresponding to the four types are provided. On this basis, policy recommendations including expanding network size, developing the driving role of network concentration, improving intermediary service system, enhancing regional external cooperation and promoting university-industry cooperation are put forward to enhance the regional innovation network development and narrow the gap among regions.
