ABSTRACT

Objective To investigate and evaluate the changes in total α and total β radioactivity levels in drinking water in Beijing, China, 2012—2021. Methods The test results of total α and total β radioactivity levels at 14 monitoring sites from 9 groundwater sources and 5 surface water sources in Beijing, 2012—2021 were collected. The radioactivity levels in the two types of water sources were compared. Statistical charts were used to show the monitoring situation at sampling sites in different regions during different periods, and related issues were explored. Results The total α and total β activity concentrations measured at monitoring sites from some water sources in Beijing, 2012—2021, were less than the total α and total β guideline values specified in the Standards for Drinking Water Quality (GB 5749—2006) (total α: 0.5 Bq/L, total β: 1.0 Bq/L). The mean total α activity concentration in the groundwater was significantly higher than that in the surface water. The total α and total β radioactivity levels in the reservoir D in the surface water were slightly higher than those in the other surface water. Conclusion In the past decade from 2012 to 2021, the total α and total β radioactivity levels in some water sources in Beijing were generally in a good condition and fluctuated within the range of environmental background values, without significant changes on the whole.

ABSTRACT

Under the leadership of the Beijing Winter Olympic Organizing Committee and the Beijing Municipal Health Commission, the Beijing Emergency Center, as the designated medical institution for the 2022 Beijing Winter Olympic Games, has completed the first aid support task of this Winter Olympic Games with other medical institutions. The author systematically analyzed the development of each link in the pre-hospital emergency support for the 2022 Beijing Winter Olympic Games, summarizes the key links of the entire Winter Olympics cycle, such as the construction of the organizational system, the formulation of support plans, and the training of support personnel, and analyzed the results of related work, so as to provide reference for the pre-hospital emergency support for China to host large-scale international events in the future.

ABSTRACT

Objective To study the electroacupuncture effects of the single point Zusanli or Sanyinjiao on simple obese rats and to observe the regulation of fat metabolism.M[ethods Before and after the treatment,the body weights and lengths of rats in each group were measured tO calculate the Lee's index;besides,total cholesteriol (TC) and triglycerides (TG) in the rat blood were also determined.Finally,the rats were treated and observed for tWO courses,and SPSS11.5 statistical software was employed to conduct statistical analysis of the experimental data.Results A significant difference was observed about the effects on the height,weight,Lee's index,TC and TG between treatment group and the model group or normal control group (P<0.05 or P<0.01),but no significant difference between treatment group and normal control group (P>0.05).Conclusion Electroacupuncture of Zusanli and Sanyinjiao points has effects on simple-obesity rats,which can make weight loss and decrease Lee's index,TC and TG levels.The underlying mechanism may relate to the improvements of fat metabolism.
