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.

OBJECTIVETo develop a brief version scale with good validity and reliability to evaluate self-management knowledge, attitude and behavior (KAB) of diabetes patients in a shorter time.

METHODS20 authority experts who specialized in the field of diabetes clinical and non-communicable disease self-management, and familiar with the relevant content of diabetes self-management were selected. Face to face and Email consultation methods were applied in two rounds delphi expert consultations to choose items from the Diabetes Self-management Knowledge, Attitude, and Behavior Assessment Scale (DSKAB, total scale, 98 items). In the first round of expert consultation, experts were asked to select the core items from every dimension and score the extent of familiarity and basis of judgment. In the second round of expert consultation, the significance of the core items which were selected by experts in first round, were graded. The items which entered into the brief scale were determined by harmonious condition of expert opinions.

RESULTSTwo rounds of consultation reclaimed 16 and 15 responses respectively, Positive coefficients of experts were 80% and 94% respectively, and both authoritative coefficients were 0.90. In the first round of consultation, experts selected 44.3 ± 6.2 items on average, 42 items were selected according to the integrity of the scale for measuring dimension and content at last. In the second round of consultation, experts thought that the 42 items could measure the important contents of each dimension comprehensive and representative, the item importance scores of knowledge, attitude, and behavior subscale were 8.42 ± 1.17, 8.61 ± 1.24, 8.61 ± 1.02 respectively, and the coordination coefficients of the three subscale were 0.36, 0.20, 0.49 (χ(2) were 89.74, 11.13, 96.03, P<0.05). The total coordination coefficient was 0.38 (χ(2) =199.36, P<0.001), which indicated the concentration of experts(')opinion was acceptable, showed the brief scale with good face validity and content validity.

CONCLUSIONThe brief scale could evaluate Diabetes Self-management KAB Scale rapidly and relatively comprehensive in groups or individuals diabetes with good face validity and content validity.

Objective:To explore the radiological protection measures for yttrium-90 ( 90Y)-loaded resin microsphere therapy in clinical application. Methods:The surgical operation process for 90Y-loaded resin microsphere therapy was simulated, involving measurement of ambient dose equivalent rates at various stages: preoperative preparation (dominated by drug package), drug transfer, intraoperative procedures (drug operation and injection), and postoperative care and observation within the hospital. Based on the simulation, the protection measures in clinical application were analyzed. Results:The dose equivalent rate ranged from 0.12 to 0.42 μSv/h around the active chamber and from 1.04 to 3.32 μSv/h in the fume hood. Around the digital subtraction angiography (DSA) room, the maximum dose equivalent rate was 0.78 μSv/h when 90Y and DSA were applied simultaneously and 0.36 μSv/h when 99Tc m and DSA were applied. For the first operating position in the fluoroscopy protection area, the maximum dose equivalent rate was 13.19 μSv/h at 155 cm height when only 90Y was applied, and 315.01 μSv/h at 80 cm height when 90Y and DSA were applied. For the second operating position, the maximum dose equivalent rate was 6.28 μSv/h at 155 cm height when only 90Y was applied and 291.03 μSv/h at the same height when 90Y and DSA were applied. The dose-equivalent rates ranged from 0.11 to 0.58 μSv/h around the dedicated ward for postoperative patients. Conclusions:The existing shielding measures, such as those in the nuclear medicine department and interventional room, meet the radiation protection requirements for 90Y-loaded resin microsphere therapy. However, it is still necessary to conduct a scientific assessment based on the actual situation. Additionally, radiation protection measures and surface contamination treatment should be enhanced during drug operation.

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.

Objective:To investigate the value of bronchoalveolar lavage fluid (BALF) genechip analysis for the identification of pathogens in children with refractory pneumonia.Methods:A retrospective study of 500 children clinically diagnosed with refractory pneumonia in the Department of Respiratory and Critical Care Medicine, Kunming Children′s Hospital, Kunming Medical University between January 2020 to January 2022 was made.During hospitalization, bronchoscopic examination and bronchoalveolar lavage were performed.BALF was collected and analyzed using genechip technology to detect potential pathogens.At the same time, bacterial culture tests of sputum and BALF samples from the patients were performed. χ2 test was used to compare the positive rates of pathogens detected by different detection methods. Results:Of the 500 children patients, 482 cases (96.4%) were positive of BALF genechip analysis for pathogen identification.There were 71 cases (14.7%) infected with a single pathogen, and 411 cases (85.3%) with 2 or more pathogens.The top 3 bacteria were Streptococcus pneumoniae [117 cases (8.3%)], Haemophilus influenzae [63 cases (4.5%)], and Bordetella pertussis [32 cases (2.3%)]. The patients were mostly infected with respiratory syncytial virus [269 cases (19.1%)], followed by parainfluenza virus [217 cases (15.4%)], and adenovirus [132 cases (9.3%)]. Among the 500 patients, 116 cases (23.2%) were positive of BALF genechip analysis for bacteria identification, 47 cases (9.4%) had a positive BALF culture, 43 cases (8.6%) had a positive sputum culture.The bacterial detection rate of BALF genechip analysis was statistically significantly higher than that of BALF culture and sputum culture tests ( χ2=34.90, 39.85; all P<0.001). Conclusions:Most patients with refractory pneumonia have mixed infections.The genechip technology can rapidly and efficiently identify the pathogens, thus providing clinical guidance for anti-infection treatment.
