Background China is a major coal producer and consumer country in the world. Coal workers' pneumoconiosis (CWP) is a primary factor endangering the occupational health of coal miners. Research on the disease burden of CWP and its changing trend is significant for disease prevention & control and associated policies. Objective To analyze the disease burden of CWP in China from 1990 to 2021 and its changing trend, and predict the disease burden from 2022 to 2035. Methods Using the Global Burden of Disease Study (GBD) database of 2021, numbers ofincident cases, prevalent cases, deaths, and disability-adjusted life years (DALYs) as well as crude and age-standardized rates of CWP in China were retrieved. Linear regression model was used to calculate the estimated annual percentage change (EAPC) of the age-standardized rates. Joinpoint regression model was used to analyze the temporal trend of disease burden and the disease burden of different sexes and age groups, and Bayesian age-period-cohort (BAPC) model was used to forecast the trend of CWP disease burden. Results In 1990, the incident, prevalent, and deaths cases of CWP in China were 3266, 18872, and 1561, respectively, and the DALYs of CWP were 44614.718 person-years. In 2021, the incident, prevalent, and deaths cases of CWP were 3446, 23975, and 1229, respectively, and the DALYs of CWP were 29610.754 person-years. From 1990 to 2021, the age-standardized incidence, prevalence, mortality, and DALYs rates of CWP in China all showed a downward trend, with the EAPCs of −3.121%, −2.532%, −4.018%, and −4.268%, respectively. The disease burden of CWP in China was mainly concentrated in the male population. The annual average percent change analysis indicated that each standardized rate showed a fluctuating downward trend in different periods. The BAPC model showed that from 2022 to 2035, the age-standardized rates of CWP in China would continue to decline steadily. In 2035, the age-standardized incidence, prevalence, mortality, and DALYs rates of CWP would be reduced to 0.10 per 100000, 0.74 per 100000, 0.03 per 100000, and 0.74 per 100000, respectively. Conclusion The disease burden contributed by CWP in China generally show a downward trend from 1990 to 2021, and it is expected that the age-standardized rates will continue to decline steadily from 2022 to 2035.

Background::Liver cancer remains the sixth most commonly diagnosed cancer and the third leading cause of cancer-related deaths worldwide, causing a heavy burden globally. An updated assessment of the global epidemiology of the liver cancer burden that addresses geographical disparities is necessary to better understand and promote healthcare delivery.Methods::Data were extracted from the GLOBOCAN 2022 database, including the number, crude, and age-standardized rates of incidence and mortality at the global, country, continent, and human development index (HDI) regional levels. Age-standardized rates (incidence and mortality) per 100,000 person-years were adjusted based on the Segi-Doll World standard population. The mortality-to-incidence ratios (MIR) for each region and country were calculated. The HDI and gross national income (GNI) for 2022 were obtained, and a Pearson correlation analysis was conducted with the incidence, mortality, and MIR.Results::In 2022, approximately 866,136 new liver cancer cases and 758,725 related deaths were recorded worldwide, with a global MIR of 0.86. Males had a disproportionately higher burden than females across all levels, and the highest burden was observed in the elderly population. Geographically, the regions with the highest incidence rates included Micronesia, Eastern Asia, and Northern Africa, and the regions with the highest mortality rates included Northern Africa, Southeastern Asia, Eastern Asia, and Micronesia. Notably, Mongolia had a strikingly high burden compared to other countries. The highest MIR was observed in North America and the lowest in Africa. Negative associations of HDI and GNI with liver cancer mortality and MIR were identified, irrespective of sex.Conclusions::The current liver cancer burden underscores the presence of remarkable geographic heterogeneity, which is particularly evident across countries with varying HDI levels, highlighting the urgent need to prioritize health accessibility and availability to achieve health inequities.

Objective To develop a Psychological Birth Trauma Assessment Scale and to test its reliability and validity.Methods Through literature review,semi-structured interview,expert conference,Delphi expert enquiry and preliminary investigation,a pre-test scale was formed.From March to May 2023,postpartum women from 38 hospitals of different levels in 15 provinces(Jiangsu,Anhui,Zhejiang,Fujian,Tibet,and Shanghai,etc.)were conveniently selected for investigation.The sample size of the first-round survey was 547,which was used for reliability and validity test.The sample size of the second-round survey was 550,which was used for confirmatory factor analysis.Results The psychological birth trauma assessment scale consisted of 2 parts,with a total of 29 items in 6 dimensions.The intrapartum feeling part included 4 dimensions,with a cumulative variance contribution rate of 63.992％,and the postpartum effect part included 2 dimensions,with a cumulative variance contribution rate of 68.208％.The content validity index of the scale was 0.947,and the content validity index of each item was 0.809～1.000.The total score of the scale and the scores of each dimension were significantly negatively correlated with the total score of the calibration scale(r=-0.784～-0.533,P＜0.001).The total Cronbach's α coefficient was 0.941,and the split-half reliability coefficient was 0.883.Confirmatory factor analysis showed that the main evaluation indicators were all within the acceptable range.Conclusion The Psychological Birth Trauma Assessment Scale has good reliability and validity,and it can be used as an assessment tool for the degree of maternal psychological birth trauma.

Objective:To investigate the change trend of etiological burden of disease of liver cancer in the Chinese population from 1990 to 2019.Methods:The descriptive epidemiologic method was conducted. Based on the Global Burden of Disease data from the Institute for Health Metrics and Evaluation at the University of Washington, the data related to liver cancer burden caused by hepatitis B virus (HBV) infection, hepatitis C virus (HCV) infection, alcohol, nonalcoholic steatohepatitis (NASH) and other factors, including number of new cases, the crude incidence rate, age-specific incidence rate, number of deaths, crude mortality rate and age-specific mortality rate, in the Chinese population from 1990 to 2019 were collected. The age-standardized rate was calculated based on the world standardized population structure in 2019 from the Global Burden of Disease data. Observation indicators: (1) the incidence of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019; (2) the mortality of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019; (3) the change trend of age-specific incidence rate of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019; (4) the age-specific mortality rate of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019. Count data were expressed as absolute numbers, percentages and ratio. Based on the junction point regression model, the Joinpoint software (V.4.9.1.0) was used to calculate the annual percentage change, average annual percentage change (AAPC) and 95% confidence intervals ( CI) of age-specific incidence rate and age-specific mortality rate of liver cancer caused by different etiologies. Results:(1) The incidence of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019. From 1990 to 2019, the number of new cases of liver cancer in Chinese population decreased from 236 825 to 210 462, and the crude incidence rate decreased from 20.01/100,000 to 14.80/100,000. The new cases of liver cancer caused by HBV infection, HCV infection and other factors showed a downward trend, and the absolute change rates were ?14.76%, ?3.98% and ?26.67%, respectively. The new cases of liver cancer caused by alcohol and NASH showed a increase trend, and the absolute change rates were 9.31% and 13.91%, respectively. (2) The mortality of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019. From 1990 to 2019, the number of deaths of liver cancer in Chinese population decreased from 232 449 to 187 700, and the crude mortality rate decreased from 19.64/100,000 to 13.20/100,000. The number of deaths of liver cancer caused by HBV infection, HCV infection and other factors showed a down-ward trend, and the absolute change rates were ?23.34%, ?10.99% and ?33.75%, respectively. The number of deaths of liver cancer caused by alcohol showed a slow downward trend, and the absolute change rate was ?0.51%. The number of deaths of liver cancer caused by NASH showed a increase trend, and the absolute change rate was 6.03%. (3) The change trend of age-specific incidence rate of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019. From 1990 to 2019, the AAPC of age-specific incidence rate of liver cancer caused by HBV infection, HCV infection, alcohol, NASH and other factors was ?3.61%(95% CI as ?4.10% to ?3.11%), ?3.57%(95% CI as ?3.99% to ?3.14%), ?2.79%(95% CI as ?3.24% to ?2.33%), ?2.65%(95% CI as ?3.09% to ?2.21%) and ?3.62%(95% CI as ?4.05% to ?3.19%), respectively. (4) The age-specific mortality rate of liver cancer caused by different etiologies in the Chinese population from 1990 to 2019. From 1990 to 2019, the AAPC of age-specific mortality rate of liver cancer caused by HBV infection, HCV infection, alcohol, NASH and other factors was ?3.92%(95% CI as ?4.42% to ?3.41%), ?3.90%(95% CI as ?4.45% to ?3.35%), ?3.15%(95% CI as ?3.71% to ?2.58%), ?2.86%(95% CI as ?3.34% to ?2.38%) and ?4.09%(95% CI as ?4.64% to ?3.55%), respectively. Conclusions:From 1990 to 2019, the liver cancer burden of the Chinese population shows an overall downward trend, in which the liver cancer burden caused by HBV and HCV infection decreases the most, but HBV and HCV infection is still the main reason for the heavy burden of liver cancer. The age-specific incidence rate and age-specific mortality rate of liver cancer caused by alcohol and NASH show a downward trend, but the number of new cases of liver cancer caused by alcohol and NASH shows significant growth. The liver cancer burden caused by other factors shows a downward trend.

Objective:To develop an objective structured clinical examination (OSCE) case base suitable for emergency nursing team training, and evaluate the quality of the case base.Methods:From June to August 2021, based on the literature research, we initially prepared the OSCE case base for emergency nursing team training through the discussion of the research group. From September to December 2021, eight experts were selected for expert group discussion, and the case base were revised and improved according to expert opinions to form a standardized OSCE case base for emergency nursing team training.

The quality evaluation score of 32 cases was (44.50±1.85) , with the lowest score 40 and the highest score 48. The case base quality evaluation score was (45.26±0.35) , with the lowest score 42 and the highest score 47.Conclusions:The overall quality of the compiled OSCE case base for emergency nursing team training is high, which is suitable for emergency nursing team training.

Objective:To explore status and influencing factors of medication deviation in elderly patients with brain infarction during the hospital-family transition, and to explore the relationship between medication deviation and adverse drug events.Methods:From November 2021 to May 2022, 218 elderly patients with brain infarction from Neurology Department of the First Affiliated Hospital of Chengdu Medical College were selected as the research objects by the convenience sampling method. General data questionnaire and Self-Efficacy for Appropriate Medication Use Scale were used to investigate patients. One month after discharge, patients were investigated by telephone using Medication Discrepancy Tool and Morisky Medication Adherence Scale with Eight-Item, and the incidence of adverse drug events was collected. Logistic regression analysis was used to explore the influencing factors of medication deviation. Spearman correlation analysis was used to investigate the correlation between adverse drug events and medication deviation. A total of 218 questionnaires were distributed in this study, and 207 valid questionnaires were effectively recovered, with an effective recovery rate of 95.0%.Results:The incidence of medication deviation in elderly patients with brain infarction was 48.8% (101/207) . Logistic regression analysis results showed that hypertension, stroke severity, medication compliance and medication quantity were the influencing factors of medication deviation ( P<0.05) . Spearman correlation analysis results showed that adverse drug events were positively correlated with medication deviation ( r=0.234, P<0.01) . Conclusions:The incidence of medication deviation in elderly patients with brain infarction during the hospital-family transition was higher. Hypertension, stroke severity, medication compliance and medication quantity were the influencing factors of medication deviation. Medical staff should formulate targeted intervention measures based on the influencing factors of medication deviation, so as to reduce the incidence of medication deviation.

Objective:To analyze the psychological experience of physical privacy protection during critical care for postoperative lung cancer patients.Methods:This study adopted the descriptive phenomenology method. From January 5 to 31, 2022, purposive sampling was used to select 20 postoperative lung cancer patients from Tongji University affiliated Shanghai Pulmonary Hospital for semi-structured in-depth interviews. The interview data was processed using the Colaizzi 7-step analysis method.Results:This study extracted 4 themes, including emphasizing privacy protection, being involuntary after operation, attitudes and reactions to privacy exposure (understanding and acceptance, complaints and doubts, indifference and conformity, shame and helplessness, sensitivity and resistance), needs and expectations (patients performing life care themselves, same-sex nursing procedures, and negotiating with patients before operation) .Conclusions:Postoperative lung cancer patients have a high sensitivity to exposing their private parts of the body during critical care. Patients have a negative psychological state after exposing their physical privacy, and there is a high need and expectation for physical privacy protection.

Objective:To explore the effect of the evidence-based practice nursing program for severe patients with physical constraints based on the guideline in Intensive Care Unit (ICU) patients.Methods:From February 2019 to July 2020, 4 663 patients in the Surgical Intensive Care Unit (SICU), Medicine Intensive Care Unit (MICU), Coronary Care Unit (CCU), and Emergency Intensive Care Unit (EICU) of the China-Japan Friendship Hospital were selected as the research object by purposive sampling. The evidence-based practice nursing program for severe patients with physical constraints based on the guideline of Promoting Safety: Alternative Approaches to the Use of Restraints was applied in clinical practice. We recorded the constraint duration, constraint rate, and substitution constraint rate of severe patients after the implementation of the program, and compared the differences in ICU nurses' scores on physical constraint knowledge, attitude, and practice before and after the implementation of the program. Results:Out of 4 663 patients, 871 received restraint, with a restraint rate of 18.68% and a restraint duration of (102.35±82.67) hours. The number of substitution constraint cases was 421, and the substitution constraint rate was 9.03%. The constraint rates in SICU, MICU, CCU and EICU were 23.68% (475/2 006), 28.26% (219/775), 7.29% (97/1 331) and 14.52% (80/551), respectively, and the differences in constraint rates among different departments were statistically significant ( P<0.05). Before and after the implementation of the program, there were statistically significant differences in the scores of ICU nurses on physical constraint knowledge, attitude, and practice dimensions and total scores ( P<0.05) . Conclusions:The evidence-based practice nursing plan program for severe patients with physical constraints based the guideline effectively reduces the rate and duration of physical constraint of ICU patients, improves the substitution constraint rate, standardizes the practice of physical constraint of ICU patients, and ensures patient safety.

A series of new monobactam sulfonates is continuously synthesized and evaluated for their antimicrobial efficacies against Gram-negative bacteria. Compound 33a (IMBZ18G) is highly effective in vitro and in vivo against clinically intractable multi-drug-resistant (MDR) Gram-negative strains, with a highly druglike nature. The checkerboard assay reveals its significant synergistic effect with β-lactamase inhibitor avibactam, and the MIC values against MDR enterobacteria were reduced up to 4-512 folds. X-ray co-crystal and chemoproteomic assays indicate that the anti-MDR bacteria effect of 33a results from the dual inhibition of the common PBP3 and some class A and C β-lactamases. Accordingly, preclinical studies of 33a alone and 33a‒avibactam combination as potential innovative candidates are actively going on, in the treatment of β-lactamase-producing MDR Gram-negative bacterial infections.
