OBJECTIVE To investigate the current usage status of OTC drug among residents in Inner Mongolia Autonomous Region， and to provide evidence for the science popularization of rational drug use. METHODS By approximate random sampling， the questionnaire survey was conducted with the mini-apps Questionnaire Star among the residents aged 19 and above from 7 league or cities of Inner Mongolia Autonomous Region， in order to investigate the current situation of OTC drug use in the region. RESULTS A total of 611 people filled in the questionnaire， and 571 people filled in the questionnaire effectively， with an effective filling rate of 93.45%. According to the results， 18.7% of residents said they did not understand the concept of OTC drugs， 36.1% of residents said they did not know the OTC drug label， and 65.3% of residents did not know the difference between class A and B OTC drugs in terms of OTC drug awareness.

Analysis of radionuclide content in the surface soil of Panjin, China / 中国辐射卫生

@#<b>Objective</b> To measure the specificactivity of natural and synthetic radionuclides in the environmental soil of Panjin, China and determine the content of radionuclides in the surface soil, and to conduct a scientific assessment of the radiation health risks of residents in this area. <b>Methods</b> Thirty-one surface soil samples were collected within the jurisdiction of Panjin, and a high-purity germanium detector was used for γ spectrum analysis to obtain the content of radionuclides and the current environmental radioactivity level. The two independent samples mean <i>t</i>-test was used to compare the specific activity data of radionuclides in soil samples between Panjin and Liaoning Province or China. <b>Results</b> The meanspecific activities of natural radionuclides ²³⁸U, ²²⁶Ra, ²³²Th, ⁴⁰K, and synthetic radionuclide ¹³⁷Cs in the surface soil samples of Panjin were 18.7 Bq/kg, 19.6 Bq/kg, 23.5 Bq/kg, 604.6 Bq/kg, and 0.9 Bq/kg, respectively. <b>Conclusion</b> The specific activities of natural and synthetic radionuclides in the surface soil samples of Panjin Area at the background level, causing a very low health risk to the people in this area.
