Therefore, the time of confirmed diagnosis after onset can be considered as a prognostic predictor. Although a few of studies work on it, factors that influence the duration remain poorly understood in different areas. Methods: This retrospective study involved patients with gastric cancer. Participants completed questionnaires by either phone or face-to-face interviews. Results: Females are with a longer interval than males. Farms lived in rural area and with New Rural Cooperative Medical Scheme are associated with a longer time interval. Patients whose income is mainly from their spouses also have a longer interval. Abdominal pain seems to be associated with longer interval time, while vomiting leads to a shorter time interval. Taking medicine after symptoms appear is associated with longer time intervals, especially those take medicine nonstandardly and more than 2 weeks. Conclusions: The results demonstrate that the medical resource in rural area should still be enhanced;meanwhile taking medicine without doctor’s advice should be cut down. Additional efforts must be made to devise strategies to properly guide patients’ behavior.展开更多

The reservoir has poor seepage capacity, strong heterogeneity, high mineralization of formation water and extremely scarce water resources on the site. These unfavorable factors have brought great difficulties to the on-site mining process. Now, a nano-composite green environmental protection slick water fracturing fluid system CQFR can be quickly dissolved because of the larger specific surface area, and the small molecular size makes the damage to the reservoir less than 5%, and the average drag reduction effect can reach more than 73%. It can quickly and well dissolve and maintain performance under high salinity conditions and fracturing flowback fluids. It responds well to the complex reservoir conditions on the construction site and makes the flowback fluid recyable, which greatly reduces the consumption of water resources on the construction site and effectively improves the construction efficiency and economic benefits.展开更多
