ABSTRACT
Objective:To investigate the behavior and emotion of trainees (residents) in the standardized residency training under the novel coronavirus pneumonia (NCP) epidemic, and adjust the training plan and mode of standardized residency training during the NCP epidemic according to the survey results.Methods:A real-name closed questionnaire survey was conducted among 40 residents (27 ultrasound majors and 13 other majors) in ultrasound department using the "Questionnaire Star" WeChat applet, including basic personal information, questions related to NCP, behavioral change survey, behavioral attitude survey and emotional status survey. All the collected data were further statistically analyzed by Chi-square test and rank sum test using SPSS 19.0Results:There were forty valid questionnaires and the participation rate was 100.0%. The accuracy of 24 NCP-related questions was not significantly different between residents majoring in ultrasound and other specialties [92.0%(596/648) vs. 93.6%(292/312), P>0.05]. All the residents had a good understanding of NCP. The main behaviors of going out were significantly reduced, while various behaviors of being at home were significantly increased. Their interest in learning declined. When the epidemic happened (or possibly) in the community or village they lived in, their negative emotions, such as nervousness, fear pessimism and depression, were obviously expressed. Network teaching and evaluation through WeChat public number were adopted and we guided residents to adjust their home behaviors and emotions according to the survey results. Conclusion:Under the NCP epidemic, the behaviors and emotions of residents had been extensively changed. The training center should adjust the teaching plan and mode of training in time, and provide more counselling service in psychology and learning for residents during the epidemic.
ABSTRACT
Objective:Four methods were used to count platelets to recommend suitable retest methods for abnormal blood platelet count.Methods:A total of 300 patients who received treatment in the Second People's Hospital of Lianyungang during August-September 2020 were included in this study. They were divided into low-value, median-value, and high-value groups ( n = 100/group) according to blood platelet counts determined by the electrical impedance method. The consistency in blood platelet counting was analyzed between flow cytometry and electrical impedance method, Neubauer chamber method, and modified blood smear method. Results:There was no significant difference in blood platelet count between the electrical impedance method [low-value group: (86.1 ± 10.3) × 10 9/L, median-value group: (221.8 ± 41.8) × 10 9/L, high-value group: (441.3 ± 51.4) × 10 9/L, Neubauer chamber method [low-value group: (85.2 ± 10.1) × 10 9/L, median-value group: (219.3 ± 37.7) × 10 9/L, high-value group: (443.1 ± 54.5) × 10 9/L, modified blood smear technique [low-value group: (86.1 ± 10.1) × 10 9/L, median-value group: (218.1 ± 37.7) × 10 9/L, high-value group: (442.6 ± 53.3) × 10 9/L], and flow cytometry [low-value group: (85.4 ± 10.1) × 10 9/L, median-value group: (220.7 ± 42.0) × 10 9/L, high-value group: (440.9 ± 50.0) × 10 9/L] (all P > 0.05). The Bland-Altman analysis revealed that the electrical impedance method, Neubauer chamber method and modified blood smear method, and flow cytometry showed consistency in blood platelet count. Conclusion:The modified blood smear method showed consistency with the electrical impedance method, Neubauer chamber method, and flow cytometry in blood platelet counting. It does not require a special instrument and can help observe cell morphology for blood platelet counting. In addition, the blood smears are easy to be preserved. The modified blood smear technique should be the first choice for re-checking blood platelet counts.
