ABSTRACT
Objective To analyze the results of national personal dose monitoring intercomparison and assessment of Hubei Provincial Hospital for Occupational Disease in 2016—2021, to investigate the influencing factors for monitoring results, and to improve the ability of personal dose monitoring. Methods The assessment was completed according to the requirements of The National Comparison Scheme for Individual Dose Monitoring Ability and Testing Criteria of Personnel Dosimetry Performance for External Exposure (GBZ 207—2016). Results The assessment results were qualified in 2016—2017 and 2020 and excellent in 2018—2019 and 2021. Conclusion The ability of personal dose monitoring in our laboratory has been continuously improved. The monitoring results are accurate and the data processing is standardized, which meet the requirements of relevant standards for personal external exposure dose monitoring.
ABSTRACT
Objective To analyze the disorder status of calcium-phosphorus metablism in maintenance hemodialysis patients. Methods Serum calcium, serum phosphorus, calcium-phosphorus product and PTH were detected in 70 patients with maintenance hemodialysis ,and compared with the indicators of K/DOQI guidelines. Results There were 36 cases over 50 years age and 34 cases less than 50 years age in 70 cases, and there were no significant differences in serum calcium, serum phosphorus, calcium-phosphorus product and PTH between two groups (P ＞0.05). The longer the dialysis, the more obvious changes of serum phosphorus and PTH levels, and there were significant differences(P ＜0.05). In 70 cases ,46 cases(65. 7%) serum calcium,34 cases(48.6%) serum phosphorus ,40 cases(57. 1%) calcium and phosphorus product,28 cases(40%) PTH met the requirement of K/DOQI guidelines,only 18 cases (25.7%) of all indicators reached the K/DOQI requirements. Conclusion The calcium-phosphorus metablism in most hemodialytic patients still cannot reach the K/DOQI guidelines.
