OBJECTIVE:To compare the new Prescription Regulatory Regime(try out)with the old“Prescription Reg?ulatory Regime”.METHODS:The2prescription regulatory regimes were analyzed in terms of law,standard operating proce?dure of drug dispensing.RESULTS&CONCLUSION:The new Prescription Regulatory Regime(try out)is operated more within the law than the old one,and in which,pharmacists’positions and responsibilities were clearly stated,the limit of checking and monitoring had been enlarged meanwhile drug dispensing standard operating procedures had been clarified.

Objective To establish a radioactive waste sorting process. Methods According to the current laws, regulations, standards, waste minimization requirements, and domestic good practices, the non-radioactive waste and radioactive waste were distinguished, and the radioactive waste was further sorted according to the different subsequent disposal methods of radioactive waste. The precautions for each step of the sorting process were described in detail. Results This process has been used in sorting decommissioned radioactive waste in an urban waste repository and achieved good results. Approximately 83 tons of radioactive waste and 1173 waste radioactive sources were sorted. Conclusion Good radioactive waste sorting technology can not only distinguish between radioactive and non-radioactive waste, but also facilitate the subsequent disposal of radioactive waste, which minimizes radioactive waste and protects staff and the environment.

Objective:To analyze the psychological anxiety and social support of HBV-carrying pregnant women and healthy pregnant women, and provide a reference for improving nursing interventions for hepatitis B virus (HBV) -carrying pregnant women.Methods:In this cross-sectional study, totally 314 pregnant women with HBV who attended outpatient services, established health files and had clear test results in a Beijing infectious disease specialist hospital from March to April 2019, and in two other ClassⅢ Grade A hospitals in the same period 420 healthy pregnant women were selected by convenient sampling. The Sociodemographic questionnaire, Self-Anxiety Scale (SAS) and Social Support Rating Scale (SSRS) were used to investigate the pregnant women.Results:There were statistically significant differences between HBV-carrying pregnant women and healthy pregnant women in education level, household registration status, family monthly income per capita, type of medical insurance, duration of pregnancy, status of pregnancy and subjective support scores ( P<0.05) . Multiple linear regression analysis controlling related factors found that whether the pregnant women carried the HBV had no effect on their psychological anxiety ( P>0.05) , and support utilization score, age, pregnancy days and education level affected the psychological anxiety of pregnant women ( P<0.05) .There was no statistically significant difference in SAS scores between the two groups of pregnant women ( t=-0.965, P>0.05) . Conclusions:The status of HBV carrying will not affect pregnant women's psychological anxiety, and factors such as social support utilization, education level, pregnancy days and age will have effect on pregnant women's psychological anxiety. It is recommended to take corresponding intervention measures to improve the utilization of social support, thereby alleviating the psychological anxiety of pregnant women.

Objective To ensure the effectiveness and improve the capacity of laboratories in the measurement of γ spectra of radionuclides. Methods A statistical analysis was performed using relative deviation, accuracy, precision, and relative combined uncertainty for the nationwide assessment of radionuclide γ spectrum measurement. Results In the assessment from 2018 to 2020, our laboratory showed qualified or above results, and the performance in 2019 was excellent. The maximum relative deviation of 11 measurements from 2018 to 2020 was 18.01%. The assessment showed |Z_test|≤1 and U_test≤2.58 in 2018, |Z_test|≤1 and U_test≤1 in 2019, and U_test≤1 and U_rel≤20% in 2020. Conclusion Our laboratory employs the correct method for radionuclide γ spectrum measurement, and the analysis data are accurate and reliable.

Objective To establishment a process of monitoring waste resin clearance in nuclear power plants, and to meet clearance requirements and simplify the monitoring work. Methods In accordance with the requirements specified in current laws, regulations, and standards in China, as well as the practice of slightly polluted waste resins generated during the operation of nuclear power plants, in-depth discussion was conducted on sampling methods, sample uniformity and representativeness tests, radiation monitoring contents and methods, and simplified monitoring processes, in order to accurately monitor the radionuclide activity of waste resins to be cleared. Results A process was established to monitor waste resin clearance in nuclear power plants. A total of 55 barrels of waste resins were cleared and the radiation levels met the requirements. Conclusion An effective clearance process can facilitate the sampling of representative resins, improve the accuracy of monitoring data, differentiate radioactive waste from cleared waste, and simplify the monitoring process. Our results provide a basis and reference for future waste resin clearance.

Objective To improve the analysis of ¹³⁴Cs, ¹³⁷Cs, and ⁶⁰Co in aerosol samples by the national key radiation environment laboratories. Methods Intercomparison of analysis results of ¹³⁴Cs, ¹³⁷Cs, and ⁶⁰Co in standard aerosol samples was performed among the national key radiation environment laboratories according to Gamma spectrometry method of analyzing radionuclides in biological samples (GB/T 16145-1995 ), and the intercomparison results were evaluated by the standard deviation. Results Six laboratories were involved in the intercomparison. For ¹³⁴Cs, 50% of the laboratories showed a relative deviation less than 10%, and 50% showed a relative deviation of 10%-20%. For ¹³⁷Cs, 33.3% of the laboratories showed a relative deviation less than 10%, and 76.7% showed a relative deviation of 10%-20%. For ⁶⁰Cs, all laboratories showed a relative deviation less than 10%. The overall intercomparison results were acceptable. Conclusion The laboratories in this intercomparison show generally good results.
