Objective To investigate the different effect of negative emotion induced by background music on verbal and spatial working memory. Methods Fifteen participants were exposed in relaxing or horrible background music and did the working memory task. After each emotional condition, the 9-point Self Assessment Manikin scale was registered. n-back paradigm was employed as WM task and the WM task contained two different types, the verbal WM and spatial WM. In the same time,The ERPs during each emotional condition was recorded,and the anterior LPC and posterior P300 were analyzed. Results The valence,arousal and dominance were 5.40±0.91,3.93 ±0.79 and 5.33 ± 1.29 in relaxing condition,while the same dimensionalities in negative condition were 2.00 ± 0.75,6.47 ± 0.99 and 2.33 ± 0.89. The self reported data showed that horrible background music induced the negative emotional state, which were observed from the decrease of valence (t(14)= 15. 902, P ＜0.01) and dominance (t(14) =6.708, P＜0.01) while the increase of arousal (t (14)=9.906, P＜0.01). The ERP data showed,there was a main effect in emotion with anterior LPC (F (1.14)= 7.37, P ＜ 0.01) and in both verbal and spatial WM,the amplitude of LPC were reduced in negative emotional condition. However, there was an interaction of emotion and type on amplitude of P300 (F (1.14)= 11.25, P ＜ 0.01), selective influence of negative emotion in spatial WM were seen (F (1.14)= 12.43, P＜0.01). Conclusion The WM was influenced by negative emotion induced by negative background music ,and the spatial WM was more vulnerable to negative emotion.

OBJECTIVE: To establish a scientific foundation for cosmetic supervision and administration based on the analysis of the sanitary quality of cosmetics in Hunan Province during 2010. METHODS: According to Cosmetic Sanitary Standards (set by the Ministry of Health, People's Republic of China), 150 random samples of cosmetics in Hunan were assayed both for microbial items (including total plate count, fungus and yeast, fecal coliform, staphylococcus aureus, pseudomonas aeruginosa) and chemical items (including 17 kinds of prohibited substances and 14 kinds of restricted substances). RESULTS: The total rate of cosmetics failing to meet the standards was 22.0% of the 150 samples; specific rates for failing perfumes, skin care products (eye cream) and deodorant products were, relatively, 70.6%, 60.00%, and 44.4%. Four kinds of prohibited substances, including diethyl phthalate, acrylamide, asbestos and neodymium, as well as 2 kinds of restricted substances, including triclosan and formaldehyde, were found to exceed standards. None of microbial items exceeded standard levels. CONCLUSION The sanitary quality control of cosmetics is lax. Administrative departments should not only reinforce their post-production supervision with respect to cosmetics, but also consolidate their control over the process of cosmetic production in order to solve the problem of toxic residues or illegal and intentional adulterations.

Objective:To explore the value of immediate bedside blood culture in the adjustment of antibiotics for children with bloodstream infections in pediatric intensive care units(PICU).Methods:Retrospective analysis of children in PICU at Henan Children′s Hospital from May 2017 to March 2021 was conducted.The cases were divided into laboratory blood culture(LBC) group and satellite blood culture(SBC) group according to different blood culture methods.The difference in the time to blood culture incubation, time to blood culture positivity, microbial results time and antibiotic adjustment time were compared between two groups.Results:A total of 3 720 blood cultures were completed in 2 718 children, including 1 888 in LBC group and 1 832 in SBC group, with a positive rate of 3.5% in LBC group and 4.9% in SBC group, and a significantly higher positive rate in SBC group compared to LBC group( χ2=3.954, P=0.046). The differences in age, sex, site of infection, survival rate at 28 d after discharge, pediatric critical illness score, and pediatric risk of mortality Ⅲ score between LBC group and SBC group with positive blood cultures were not statistically significant ( P>0.05). Children in SBC group had significantly shorter specimen receipt time, time to obtain microbiological results, and antibiotic adjustment time than those in LBC group[0.33(0.03, 1.78) h vs. 3.38(1.38, 7.29) h, (57.40±21.92) h vs. (68.14±21.26) h, and (52.53±27.23) h vs. (66.41±28.57) h, all P<0.05]. Conclusion:Immediate bedside blood culture shortens the time from culture to final result reporting, increases the positive rate of blood culture, and saves time on accurate antibiotic treatment for critically ill children.

With the awareness of the hazards of ionizing radiation to human health and the consequent research on the biological effects and protective measures against ionizing radiation, the radiological health has gradually developed. Therefore, as one of the five major areas of health under the traditional public health system, the study on radiological health mainly involves the harmful effects of ionizing radiation on human health and its comprehensive protection measures. After nearly a century of vigorous development ince the 1930 s and 1940 s, the level of the discipline of the radiological health and the effectiveness of radiological hygiene work in China have been greatly improved at this stage. This paper provides a brief overview of the history, current status, and work content of the radiological health research and radiological hygiene work in China, with a view to contributing to the future development of radiological hygiene work in China.

Objective:To analyze distributions of dose range, occupational category, and causes of abnormal dose values from individual dose monitoring of radiation workers and to provide recommendations for improving the quality of individual monitoring data and occupational health management in medical institutions.Methods:The data of individual dose monitoring result exceeding 1.25 mSv in a single monitoring cycle, collected by Occupational Health System for Radiology Facilities’ on National Radiological Health Information Platform, was analyzed.Results:A total of 1 113 abnormal dose values were detected in 31 provinces in 2020, with an abnormal rate of 2.48‰, of which workers of diagnostic radiology and interventional radiology accounted for 68.01% and 18.78%, respectively. The dose distribution of abnormal dose values was mainly between 1.25 and 5 mSv. The abnormal dose values were mainly caused by improperly wearing or using personal dosimeters, accounting for 63.88%. Workers for whom the dose values was abnormal due to increased workload accounted for 12.32%, with an average annual individual dose of 5.14 mSv. There was no statistically significant difference in annual individual dose among radiation workers between different occupational groups( P>0.05). Conclusions:Education and training on radiation protection for radiation workers should be strengthened, and a specific and feasible system for radiation protection management, as well as a reward and punishment system, should be established in order to reduce the occurance of the improper wearing of personal dosimeters. Great attention should be paid to occupational exposure of workers in diagnostic radiology and interventional radiology, and a work shift system should be conducted to reduce individual dose levels. It is recommended that standard verification procedures for abnormal dose values from individual dose monitoring should be developed to improve the quality of individual monitoring data.

In March 2011, a nuclear accident happened and released a large amount of radionuclides into the environment in Fukushima, Japan. This review introduced the latest findings on the relationship between childhood thyroid cancer and radiation exposure after the accident in Fukushima. Many reports suggested that there was no accurate correlation between the incidence of childhood thyroid cancer and the local external dose due to the accident at the Fukushima Daiichi nuclear power, while the relationship between the two varied with method of dose calculation and statistics. Also there was no clear evidence that radiation exposure had a negative impact on children′s thyroid, and the increased incidence of thyroid cancer may be due to over-screening.

Objective To summarize the clinical characteristics of delayed diagnosis of tuberculosis in children,analyze the risk factors of delayed diagnosis,and support early diagnosis of tuberculosis in children.Methods This is a retrospective analysis based on the clinical data of tuberculosis patients admitted to the Children's Hospital Affiliated to Zhengzhou University from January 2015 to February 2023.The clinical characteristics of children were analyzed in terms of age group.According to the definition of diagnosis delay,the patients were assigned to delayed group and non-delayed group.Univariate analysis and multivariate logistic regression were used to analyze the risk factors for diagnosis delay.Results A total of 82 children with tuberculosis were included(46 cases in delayed diagnosis group and 36 cases in non-delayed diagnosis group).The rate of diagnosis delay was 56.1％.The incidence of acute miliary pulmonary tuberculosis and tuberculous meningitis was significantly higher in children ≤5 years old than that in children＞5 years old(P＜0.05).Diagnosis delay was associated with significantly higher prevalence of chronic fever,cough＞2 weeks,growth retardation and significantly longer duration of empirical antibiotic use compared to the children without diagnosis delay(P＜0.05).Univariate analysis showed that patient origin,contact history,mixed infection,tuberculosis type,molecular biological assay and severe disease were related to the delay of TB diagnosis(P＜0.05).Multivariate logistic regression analysis showed that patient origin[≥3 clinic visits(OR=7.064,95％CI:1.677-29.754)],mixed infection(OR=3.812,95％CI:1.185-12.260),severe disease(OR=3.697,95％CI:1.081-12.646)]were risk factors for diagnosis delay in children.Molecular biological assay(OR=4.642,95％CI:1.318-16.345)was a protective factor.Conclusions The clinical symptoms of tuberculosis in children are atypical.Delayed diagnosis of tuberculosis is common.Multiple clinic visits,mixed infection,and severe disease are the risk factors for diagnosis delay.Tuberculosis should be taken into account for the children with chronic fever,cough and growth retardation who have failed to respond to adequate therapy with third-generation cephalosporin and carbapenems.Molecular biological assay is helpful for early diagnosis of tuberculosis in children with negative sputum smear.

Objective:To investigate and analyze the eye lens dose to interventional radiology workers in China from 2019 to 2021.Methods:The monitoring data on eye lens dose to interventional radiology workers from 31 province-level units during 2019-2021 were collected through the National Radiological Health Information Platform. The eye lens dose evaluation indicator was Hp(3), with each monitoring period of no more than 3 months. Kusall-Wallis H test was used for the comparison of multiple groups and pairwise. Results:A total of 6 643 interventional radiology workers were investigated from 2019 to 2021. The average annual eye lens dose was 1.03 mSv, with the median of 0.17 mSv and the maximum of 94.88 mSv. The annual eye lens dose to 59 workers exceeded 20 mSv. It was also found that the annual eye lens dose to the doctors in 2019 and 2020 was slightly higher than that to nurses (rank mean difference=118.29, 129.71, P<0.01), and the lens dose to interventional radiology workers who performed cardiac interventions in 2019 was higher than that to workers who performed peripheral vascular interventions (rank mean difference=46.52, P<0.05). Conclusions:The lens dose to interventional radiology workers is lower than the limits given in Chinese national standard currently in effect, but exceed the latest internationally recommended limit for a few ones. In order to protect the occupational health of interventional radiology workers, the monitoring of lens dose should be strengthened.
