In order to understand the knowledge, attitude and practice (KAP) of vaccination against influenza, pneumonia, human papillomavirus (HPV), herpes zoster (HZ), COVID-19, and hepatitis B among staff of vaccination units in Shandong Province, a sample survey was conducted among 797 staffs of adult vaccination units in 12 counties (cities and districts) of Shandong Province from August to September 2022. The results showed that the respondents had the highest total score of knowledge and attitude for the COVID-19 vaccine, with the M ( Q1, Q3) of 23 (20, 25) and 10 (10, 10), respectively, and had the lowest score of knowledge and attitude for the herpes zoster vaccine, with the M ( Q1, Q3) of 19 (15, 22) and 8 (8, 10), respectively. The vaccine-related knowledge point"vaccine applicable population"had the highest score, with the M (Q1, Q3) of 26 (23, 30). The "contraindications/adverse reactions" and "adverse reaction management" had the lowest score, with the M (Q1, Q3) of 24 (20, 29) and 24 (20, 28), respectively. About 89.71% of respondents received one adult vaccine within two years at least. The principal driver for vaccination of 53.58% of recipients was their understanding of vaccines, which was"it was necessary to receive the vaccine". About 66.00% of respondents who had not received any adult vaccine in the past two years had insufficient awareness of the necessity of vaccination and believed that they were in good health and did not need to receive it. In summary, the staff of adult vaccination units in Shandong Province have a poor understanding of the herpes zoster vaccine in terms of vaccines and a relatively poor understanding of"contraindications/adverse reaction and management"in adult vaccination knowledge points.

Objective: To examine the effects of air pollution on overall mortality, mortality of respiratory diseases, and mortality of circulatory diseases among residents in Hangzhou City. Methods: Residents' mortality data in Hangzhou City from 2014 to 2016 were captured from Zhejiang Provincial Chronic Disease Surveillance Information Management System, and the ambient air quality in Hangzhou City from 2014 to 2016 were collected from Hangzhou Environmental Monitoring Center, while the meteorological monitoring data during the study period were collected from Hangzhou Meteorological Bureau. The effects of PM2.5, PM10, NO2 and SO2 on overall mortality, morality of respiratory diseases and mortality of circulatory diseases were evaluated a generalized additive model (GAM) based on Poisson distribution, and the risk of mortality was described with excess risk (ER) and its 95%CI. Results: The daily M (QR) overall deaths, deaths from respiratory diseases and deaths from circulatory diseases were 111 (30), 16 (9) and 37 (14) persons in Hangzhou City from 2014 to 2016, respectively. A 10 μg/m3 increase in PM2.5, PM10, NO2 and SO2 resulted in 0.47% (95%CI: 0.23%-0.70%), 0.37% (95%CI: 0.21%-0.53%), 1.06% (95%CI: 0.50%-1.61%) and 3.08% (95%CI: 2.18%-3.99%) rises in the risk of overall mortality, 0.60% (95%CI: 0.04%-1.16%), 0.45% (95%CI: 0.06%-0.83%), 2.01% (95%CI: 0.84%-3.20%) and 6.06% (95%CI: 3.80%-8.37%) rises in the risk of mortality of respiratory diseases, and 0.45% (95%CI: 0.08%-0.83%), 0.44% (95%CI: 0.17%-0.71%), 1.43% (95%CI: 0.49%-2.37%) and 3.66% (95%CI: 2.13%-5.22%) rises in the risk of mortality of circulatory diseases, and the greatest effect was observed at a 2-day lag. Multi-pollutant model analysis showed that, after adjustment for PM2.5, NO2 and PM2.5+NO2+SO2, a 10 μg/m3 increase in SO2 resulted in an elevated risk of mortality of respiratory diseases than a single-pollutant model. Conclusions The air pollutants PM10, PM2.5, NO2, and SO2 correlated positively with the risk of overall mortality, mortality of respiratory diseases and mortality of circulatory diseases in Hangzhou City from 2014 to 2016, and the co-existence of multiple pollutants enhanced the effect of SO2 on mortality of respiratory diseases.

Objective: To investigate the pulmonary functions among the elderly in Hangzhou City, so as to provide insights into the management of respiratory diseases among the elderly. Methods: Permanent residents at ages of 60 to 75 years were sampled from Hangzhou City from November to December 2020. The pulmonary function was tested using a portable pulmonary function monitor, including large airway function parameters [forced expiratory volume (FVC), forced expiratory volume in a second (FEV1) and FEV1/FVC], and small airway function parameters [maximum expiratory flow rate at 75% vital capacity (MEF75%), the maximum expiratory flow rate at 25% of vital capacity (MEF25%) and the forced expiratory flow rate (FEF25%-75%) at 25% to 75% of vital capacity]. The pulmonary functions were compared among the elderly with different genders, ages and body mass index (BMI). Results : Totally 314 participants were recruited, including 126 men (40.13%), with a mean age of (68.49±4.47) years and mean BMI of (23.51±2.79) kg/m2.

Higher FEV1 [(2.22±0.55) vs. (1.79±0.43) L, P<0.05], FVC [(2.92±0.75) vs. (2.24±0.55) L, P<0.05], MEF75% [(4.19±1.82) vs. (3.59±1.49) L/s, P<0.05] and FEF25%-75% [(2.14±1.07) vs. (1.90±0.77) L/s, P<0.05] were tested among men than among women, and lower FEV1 [(1.75±0.46) L], FVC [(2.27±0.64) L], MEF25% [(0.88±0.57) L/s], MEF75% [(3.39±1.45) L/s] and FEF25%-75% [(1.79±0.96) L/s] were tested among the elderly at ages of 70 to 74 years. The proportion of large and small airway dysfunctions was 40.45% among the participants. Conclusions The proportion of large and small airway dysfunctions was 40.45% among the elderly in Hangzhou City, and poor pulmonary functions were tested among the women and the advanced elderly.

Lead poisoning severely threatens human health with its cumulation and durability in the body. The analysis of lead in blood is vital for screening, diagnosis, treatment, and prognostication of lead poisoning and for indirectly monitoring the level of lead in the environment. Although the detection programs are available throughout our country, the accuracy and comparability of the results cannot meet the expectation. A variety of factors can affect the accuracy of blood lead testing. To promote the application of blood lead analysis in clinical trials and reduce the bias of results, a better reference system for blood lead analysis should be established to evaluate the accuracy of traditional methods, promote the standardization of blood lead analysis and achieve accurate blood lead testing.

Objective:To explore the application value of case-based learning (CBL) and problem-based learning (PBL) dual-track teaching mode in the standardized resident training in laboratory medicine.Methods:The students of Grade 2017 and Grade 2018, who underwent standardized resident training of laboratory medicine in the Second Affiliated Hospital of Wenzhou Medical University from September 2017 to June 2021, were selected in this study. Seven students of Grade 2017 were served as the traditional lecture teaching group (traditional teaching group), and 12 students of Grade 2018 were assigned to the CBL-PBL dual-track teaching mode group (CBL-PBL group). Students of the two groups received 22 months of laboratory specialty training, and underwent one admission theory assessment,two mid-term theory assessments, annual professional level test, final theory assessment, final practical skills assessment as well as questionnaire survey. The questionnaire was distributed and finished anonymously after the final assessment. Survey indicators included ability assessment on solving clinical problem, assessment on the theoretical knowledge, computer operation skill, preparation time before teaching, teaching method satisfaction degree and clinical recognition. The results were divided into 5 categories: extremely agree, agree, general, disagree and extremely disagree, respectively (ranked as 5, 4, 3, 2, and 1). The Cronbach′s α coefficient was used to analyze the reliability of the questionnaire.Results:The mid-term theory assessment, annual professional level test and assessment results of clinical outcome interpretation were significantly higher in CBL-PBL dual-track teaching mode group than those in traditional lecture teaching group (all P<0.05). The performance after standardized resident training was significantly higher in the CBL-PBL group than in the traditional teaching group ( P<0.05). The Cronbach′s α coefficient of questionnaire reliability analysis was 0.938. Parameters assessment results including improved clinical problem-solving skills, computer operation skill, the ability to analyze and solve problems, the ability of innovation and adaptation, the learning interest, the ability of autonomous learning, teaching method satisfaction and conventional application to clinical recognition scores were all significantly better in the CBL-PBL group than those in the traditional teaching group (all P<0.05). Conclusion:The application of CBL-PBL dual-track teaching mode for the standardized resident training in laboratory medicine can effectively improve the assessment results and performance of students undergoing standardized resident training, and help to cultivate high quality medical laboratory professionals.

Objective: To investigate the pH value of towels in public places in Hangzhou City, so as to provide the evidence for improving health supervision of towels in public places. Methods: One three- and higher-star hotel, one less than three-star hotel, one express hotel, one barber shop and one beauty shop were selected from 13 counties (districts) of Hangzhou City in 2021, and 3% to 5% of all cleaned and disinfected towels that planned to be used were randomly sampled. The type of public places and towels cleaning and disinfection were collected using the basic investigation form provided in the Public Place Health Risk Factors Surveillance Program (2021 version), and the pH value of towels was measured according to the national criteria Textiles-determination of pH of aqueous extract (GB/T 7573-2009). According to the national criteria of Hygienic indicators and limits for public places (GB 37488-2019), a pH value of 6.5 to 8.5 was defined qualified, and the rates of qualified pH values was estimated for towels sampled from different places and with different cleaning and disinfection types. Results: Totally 64 public places were investigated, and 807 towels were measured for pH values, with a median pH value of 7.3 (interquartile range, 0.7). A total of 655 towels had qualified pH values (81.16%). The rates of qualified pH values were 84.95%, 75.56%, 73.21%, 85.61% and 88.81% for towels sampled from the three- and higher-star hotel, less than three-star hotel, express hotel, barber shop and beauty shop, respectively (χ2=19.307, P=0.001). The rate of qualified pH values for self-cleaned and -disinfected towels was significantly higher than for towels with outsourcing cleaning and disinfection services (88.28% vs. 77.18%; χ2=14.973, P<0.001). The rate of qualified pH values was 83.82% for towels with outsourcing cleaning and disinfection services sampled from the three- and higher-star hotel, and was both 100.00% for self-cleaned and -disinfected towels sampled from the less than three-star hotel and beauty shop. Conclusion The cleaning quality of towels remains to be improved in public places in Hangzhou City, and health supervisions on towels are recommended to be improved in public places.

Objective:To explore the mediating effect of nurses′ self-efficacy in palliative care between the past behavioral experience of end-of-life care and core competence, and provide theoretical reference for improving the core competence of clinical nurses in palliative care.Methods:579 clinical nurses from 2 tertiary general hospitals in Shandong Province were investigated by convenience sampling method using general information questionnaire, nurses′ self-efficacy questionnaire for palliative care and palliative care nurses′ core competency questionnaire. The data were analyzed by SPSS 25.0.Results:The total score of core competence of hospice care of 579 nurses was (71.41 ± 22.74), nurses′ self-efficacy of palliative care was positively correlated with their core competence ( r = 0.648, P<0.01), past behavior experience was positively correlated with self-efficacy ( r = 0.479, P<0.01), positively correlated with core competence ( r = 0.427, P<0.01). Nurses′ self-efficacy of palliative care played a partial mediating role between the pastbehavioral experience and core competence, which accounted for 64.67% of the total effect. Conclusions:The past behavioral experience of end-stage nursing can directly or indirectly affect the core competence of nurses in palliative care through self-efficacy. It can improve the core competence of palliative care by taking active measures to enrich the past behavioral experience of end-of-life care and improve self-efficacy.
