ABSTRACT
@#<b>Objective</b> To investigate the number and categorical distribution of non-medical radiation institutions in Fujian Province, China, and to explore the current situation of radiation occupational hazards prevention and control and the occupational health management of radiation workers in employing units. <b>Methods</b> The industrial enterprises engaged in the application of nuclear technology in our province were investigated, and different types of employing units were selected to monitor the radioactivity level in the workplace. <b>Results</b> A total of 377 non-medical radiation institutions were reported in the province, with a total of 5221 radiation workers (except luggage detector units); 1246 radiation workers held radiation worker certificates, accounting for 23.87%; 5103 radiation workers carried out personal dose monitoring, accounting for 97.74%; 5061 radiation workers participated in radiation protection knowledge training, accounting for 96.94%; a total of 4895 (93.76%)radiation workers received physical examination. <b>Conclusion</b> Health supervision authorities in Fujian Province should strengthen the supervision of non-medical radiation institutions, further improve the level of occupational health management, and protect the health rights and interests of radiation workers to the maximum extent.
ABSTRACT
AIM: To evaluate the pharmacokinetics and bioequivalence of cetirizine hydrochloride tablets under fasting and fed conditions in Chinese healthy subjects. METHODS: This was a randomized, open-label, double-sequence, two-period, crossover designed study, and healthy subjects enrolled and administrated a single dose of 10 mg test and reference cetirizine hydrochloride tablets in each period under fasting or fed condition. The plasma concentrations of cetirizine were determined by a validated LC-MS/MS method. The pharmacokinetic parameters were calculated with WinNonlin 6.3 and the bioequivalence was evaluated through SAS 9.4 software. RESULTS: In the fasting condition, the major pharmacokinetic parameters of cetirizine of test and reference formulations were as follows, C
