With the rapid development of nuclear medicine, the number of nuclear medical staff has increased a lot in the past few years in China. Close-range operations, such as preparation and injections of radiopharmaceuticals, are usually carried out in nuclear medicine department. And the use of unsealed radionuclides may also create internal exposure risk. So, occupational exposure of nuclear medical staff is a main issue of occupational health management in China. In this paper, the occupational exposure level and requirements for radiation protection of nuclear medical staff are introduced to provide references for the related work that radiological health technical institutions carry out.

Objective: To assess the current situation of early treatment of partial-thickness burn wounds by professional burn medical staff in China, and to further promote the standardized early clinical treatment of partial-thickness burn wounds. Methods: A cross-sectional investigation was conducted. From November 2020 to February 2021, the self-designed questionnaire for the early treatment of partial-thickness burn wounds was published through the "questionnaire star" website and shared through WeChat to conduct a convenient sampling survey of domestic medical staff engaged in burn specialty who met the inclusion criteria. The number, region, and grade of the affiliated hospital, the age, gender, occupation, and seniority of the respondents were recorded. The respondents were divided into physician group and nurse group, senior group and junior group, eastern region group and non-eastern region group, primary and secondary hospital group and tertiary hospital group. Then the seniority, grade of the affiliated hospital, region of the affiliated hospital of the respondents in physician group and nurse group, conventional treatment of partial-thickness burn blisters, reasons for retaining vesicular skin, reasons for removing vesicular skin, and the conventional selection and optimal solution recommendation of topical drugs or dressings for partial-thickness burn wounds in the early stage of respondents in each of all the groups were recorded. Data were statistically analyzed with chi-square test. Results: The survey covered 31 provinces, municipalities, and autonomous regions in China (except for Hong Kong, Macau, and Taiwan regions). A total of 979 questionnaires were recovered, which were all valid. The 979 respondents came from 449 hospitals across the country, including 203 hospitals in the eastern region, 116 hospitals in the western region, 99 hospitals in the central region, and 31 hospitals in the northeast region, 348 tertiary hospitals, 79 secondary hospitals, and 22 primary hospitals. The age of the respondents was (39±10) years. There were 543 males and 436 females, 656 physicians and 323 nurses, 473 juniors and 506 seniors, 460 in the eastern regions and 519 in the non-eastern regions, 818 in tertiary hospitals and 161 in primary and secondary hospitals. There were statistically significant differences in the composition of different seniority in the respondents between physician group and nurse group (χ²=44.32, P<0.01), while there were no statistically significant differences in grade or region of the affiliated hospital of the respondents between physician group and nurse group (P>0.05). There were no statistically significant differences in the conventional treatment of partial-thickness burn blisters among respondents between different occupational groups, seniority groups, and region of the affiliated hospital groups (P>0.05).The respondents in different grade of the affiliated hospital groups differed significantly in the conventional treatment of partial-thickness burn blisters (χ²=6.24, P<0.05). Compared with respondents in nurse group, larger percentage of respondents in physician group chose to retain vesicular skin for protecting the wounds and providing a moist environment, and alleviating the pain of dressing change (with χ² values of 21.22 and 19.96, respectively, P values below 0.01), and smaller percentage of respondents in physician group chose to retain vesicular skin for prevention of wound infection (χ²=23.55, P<0.01). The reasons for retaining vesicular skin of respondents between physician group and nurse group were similar in accelerating wound healing, alleviating pigmentation and scar hyperplasia post wound healing (P>0.05). Compared with respondents in junior group, larger percentage of respondents in senior group chose to retain vesicular skin for protecting the wounds and providing a moist environment and alleviating the pain of dressing change (with χ² values of 10.36 and 4.60, respectively, P<0.05 or P<0.01), and smaller percentage of respondents in senior group chose to retain vesicular skin for prevention of wound infection (χ²=8.20, P<0.01). The reasons for retaining vesicular skin of respondents in senior group and junior group were similar in accelerating wound healing, alleviating pigmentation and scar hyperplasia post wound healing (P>0.05). The 5 reasons for the respondents between eastern region group and non-eastern region group, primary and secondary hospital group and tertiary hospital group chose to retain vesicular skin were all similar (P>0.05). Compared with those in physician group, significantly higher percentage of respondents in nurse group were in favor of the following 6 reasons for removing the vesicular skin, including convenience for using more ideal dressings to protect the wounds, prevention of wound infection, facilitating the effect of topical drugs on the wounds, the likely rupture of blisters and wound contamination, accelerating wound healing, and alleviating pigmentation and scar hyperplasia post wound healing (with χ² values of 4.35, 25.59, 11.83, 16.76, 46.31, and 17.54, respectively, P<0.05 or P<0.01). Compared with respondents in senior group, larger percentage of respondents in junior group chose to remove vesicular skin for the reasons such as the likely blister rupture and wound contamination, preventing wound infection, accelerating wound healing, and alleviating pigmentation and scar hyperplasia post wound healing (with χ² values of 17.25, 18.63, 14.83, and 10.23, respectively, P values below 0.01). Compared with respondents in non-eastern region group, larger percentage of respondents in eastern region group chose to remove vesicular skin for preventing wound infection and the likely rupture of blisters and wound contamination (with χ² values of 9.30 and 8.65, respectively, P values below 0.01). The 6 reasons for the respondents between tertiary hospital group and primary and secondary hospital group choose to remove vesicular skin were similar (P>0.05). Compared with respondents in physician group, larger percentage of respondents in nurse group chose to use moisturizing materials for partial-thickness burn wounds in the early stage (χ²=6.18, P<0.05), and smaller percentage of respondents in nurse group chose other topical drugs or dressings (χ²=5.20, P<0.05). Compared with respondents in junior group, larger percentage of respondents in senior group chose to use moisturizing materials and other topical drugs or dressings for partial-thickness burn wounds in the early stage (with χ² values of 4.97 and 21.80, respectively, P<0.05 or P<0.01). Compared with respondents in non-eastern region group, larger percentage of respondents in eastern region group chose to use topical antimicrobial drugs for partial-thickness burn wounds in the early stage (χ²=4.09, P<0.05), and smaller percentage of respondents in eastern region group chose to use other topical drugs or dressings for the partial-thickness burn wounds in the early stage (χ²=5.63, P<0.05). Compared with respondents in primary and secondary hospital group, larger percentage of respondents in tertiary hospital group chose to use biological dressings for partial-thickness burn wounds in the early stage (χ²=9.38, P<0.01). The optimal solution recommendation of topical drugs or dressings for partial-thickness burn wounds in the early stage varied significantly among the respondents between different occupational groups and seniority groups (with χ² values of 39.58 and 19.93, respectively, P values below 0.01). There were no statistically significant differences between eastern and non-eastern region groups, tertiary hospital group and primary and secondary hospital groups in optimal solution recommendation of topical drugs or dressings for partial-thickness burn wounds in the early stage (P>0.05). Conclusions: The conventional treatment measures of partial-thickness burn blisters and reasons for preserving blister skin by professional burn medical staff in China are relatively consistent, but there are great differences in the selection of reasons for removing blister skin, the conventional selection and optimal solution recommendation of topical drugs or dressings for partial-thickness burn wounds in the early stage. Therefore, it is urgent to establish a clinical treatment standard for partial-thickness burn wounds.

Objective: To investigate the current situation of safety protection of medical staffs in medical institutions in Jiangsu Province, and to provide scientific basis for strengthening the safety protection of infectious diseases and protecting the occupational health of medical staffs. Methods: From September to October 2020, 1274 medical staffs in 43 medical and health institutions were randomly selected as the subjects. The self-made questionnaire for infectious disease prevention and protection was used to analyze the pre-job training and exposure to occupational harmful factors of the respondents. The influencing factors of using protective equipment and occupational injury were analyzed by binary logistic regression. Results: A total of 1216 valid questionnaires were collected with effective recovery of 95.4%. There were 312 males (25.7%) and 904 females (74.3%) , with an average age of (35.8±9.2) years and average working years of (13.6±9.9) years. Among them, 1143 (94.0%) had participated in pre-job training, 535 (44.0%) thought they were exposed to occupational harmful factors of infectious disease prevention, 1082 (89.0%) used protective equipment in daily operation, and 462 (38.0%) had occupational injury. According to binary logistic regression analysis, the utilization rates of protective equipment for medical staffs in Centers for Disease Control and Prevention (OR=2.473, 95%CI: 1.327-4.607, P=0.004) , 30-39 years old (OR=1.586, 95%CI: 1.038-2.426, P=0.033) , 40-49 years old (OR=2.257, 95%CI: 1.243-4.098, P=0.007) , 50 years old and above (OR=5.879, 95% CI: 1.755-19.692, P=0.004) and pre-job training (OR=2.580, 95%CI: 1.301-5.116, P=0.007) were higher than their respective control groups. And medical staffs with graduate degree or above (OR=0.342, 95%CI: 0.167~0.699, P=0.003) had lower utilization rate of protective equipment. Female (OR=1.902, 95%CI: 1.364-2.654, P<0.001) , 30-39 years old (OR=1.589, 95%CI: 1.157-2.181, P=0.004) , bachelor degree (OR=2.070, 95%CI: 1.419-3.021, P<0.001) , exposure to occupational harmful factors (OR=2.753, 95%CI: 2.086-3.634, P<0.001) were the risk factors for occupational injury of medical staffs. Centers for Disease Control and Prevention (OR=0.129, 95%CI: 0.086-0.194, P<0.001) and wearing protective equipment according to regulations (OR=0.597, 95%CI: 0.431-0.827, P=0.002) were the protective factors for occupational injury of medical staffs. Conclusion: At present, the occupational injury rate of medical staffs in Jiangsu Province is high due to various factors in the prevention and control of infectious diseases. It is necessary to pay attention to occupational safety protection, strengthen pre-job training and actively advocate "standard prevention", so as to reduce the exposure risk of harmful factors and promote occupational health of medical staffs.

OBJECTIVES: To investigate the current status of the cognition of neonatal pain assessment and analgesia management among medical staff in the neonatal intensive care unit (NICU). METHODS: A self-made scale was developed according to "Expert consensus on neonatal pain assessment and analgesia management (2020 edition)" and was used to distribute questionnaires to the medical staff in the NICU from the member units of Jiangsu Province Medical Quality Control Centre of Neonatal Department to evaluate their levels of understanding the basic knowledge, assessment, and management of neonatal pain. RESULTS: A total of 957 questionnaires (from 383 doctors and 574 nurses) were collected. Doctors and nurses had mean correct rates of 38% and 39% respectively in answering the questions on the basic knowledge of neonatal pain. They had median correct rates of 0% and 50% respectively in answering the questions on neonatal pain assessment, and mean correct rates of 73% and 68% respectively in answering on analgesia management. Compared with those who did not receive the training on neonatal pain, the medical staff who received such training had significantly higher correct rates in answering the questions on the basic knowledge of neonatal pain and neonatal pain assessment ( CONCLUSIONS The medical staff in the NICU have insufficient cognition of neonatal pain, and thus it is necessary to carry out the special training on neonatal pain, focusing on the promotion and practical application of "Expert consensus on neonatal pain assessment and analgesia management (2020 edition)", in order to improve the level of neonatal pain assessment and analgesia management among medical staff in the NICU.

OBJECTIVE: To determine the environmental contamination degree of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in corona virus disease 2019 (COVID-19) wards, to offer gui-dance for the infection control and to improve safety practices for medical staff, by sampling and detecting SARS-CoV-2 nucleic acid from the air of hospital wards, the high-frequency contact surfaces in the contaminated area and the surfaces of medical staff's protective equipment in a COVID-19 designated hospital in Wuhan, China. METHODS: From March 11 to March 19, 2020, we collected air samples from the clean area, the buffer room and the contaminated area respectively in the COVID-19 wards using a portable bioaerosol concentrator WA-15. And sterile premoistened swabs were used to sample the high-frequency contacted surfaces in the contaminated area and the surfaces of medical staff's protective equipment including outermost gloves, tracheotomy operator's positive pressure respiratory protective hood and isolation clothing. The SARS-CoV-2 nucleic acid of the samples were detected by real-time fluorescence quantitative PCR. During the isolation medical observation period, those medical staff who worked in the COVID-19 wards were detected for SARS-CoV-2 nucleic acid with oropharyngeal swabs, IgM and IgG antibody in the sera, and chest CT scans to confirm the infection status of COVID-19. RESULTS: No SARS-CoV-2 nucleic acid was detected in the tested samples, including the 90 air samples from the COVID-19 wards including clean area, buffer room and contaminated area, the 38 high-frequency contact surfaces samples of the contaminated area and 16 surface samples of medical staff's protective equipment including outermost gloves and isolation clothing. Moreover, detection of SARS-CoV-2 nucleic acid by oropharyngeal swabs and IgM, IgG antibodies in the sera of all the health-care workers who participated in the treatment for COVID-19 were all negative. Besides, no chest CT scan images of medical staff exhibited COVID-19 lung presentations. CONCLUSION Good ventilation conditions, strict disinfection of environmental facilities in hospital wards, guidance for correct habits in patients, and strict hand hygiene during medical staff are important to reduce the formation of viral aerosols, cut down the aerosol load, and avoid cross-infection in isolation wards. In the face of infectious diseases that were not fully mastered but ma-naged as class A, it is safe for medical personnel to be equipped at a high level.

OBJECTIVES: To explore the psychological status of medical staff in the epidemic period of coronavirus disease 2019 (COVID-19), and to analyze its influential factors. METHODS: A total of 373 medical staff from Xiangya Hospital and the Second Xiangya Hospital of Central South University were enrolled for this study. The General Sociological Data Questionnaire, Symptom Check-List 90 (SCL-90), and self-designed public opinion response questionnaire were used to assess general sociological data, mental health scores, and ability to respond to COVID-19 related public opinion information of medical staff. The mental health scores of medical staff with different general sociological data and public opinion information coping abilities were compared. Influential factors of mental health were analyzed. RESULTS: The average score of 10 factors in SCL-90 of 373 medical staff was less than 2 points. 14.21% medical staff had one or more factor scores more than two points, including 11.26% with terror symptoms, 7.77% with compulsive symptoms, and 5.63% with anxiety. The main sources of COVID-19 information for medical staff included WeChat, microblog, Jinri toutiao, TV and radio. 66.22% medical staff regularly verified information about COVID-19 through official websites or formal channels. A great deal of COVID-19 information in WeChat could make medical staff nervous (34.05%), anxious (30.29%), and insecure (29.22%). 68.63% medical staff sometimes were worried about getting infected because they knew information about COVID-19. Different departments of medical staff, getting cough or having a fever recently, and the degree of fear of infection had an impact on the SCL-90 score of medical staff, the differences were all statistically significant (all <0.05). Stepwise regression analysis showed that the impact of COVID-19 information on their life in WeChat, getting cough or having a fever recently, insomnia-early caused by COVID-19 information in WeChat, different departments, and the degree of fear of infection COVID-19 were the influential factors for the mental health of medical staff (all <0.05). CONCLUSIONS During the epidemic of COVID-19, medical staff suffered from psychological problems to various degrees. It is necessary to establish a psychological assistance platform and guide the direction of public opinion correctly to promote the mental health of medical staff.
