Emerging evidence suggests that dysbiosis of the gut microbiota is associated with the pathogenesis of Parkinson's disease (PD), a prevalent neurodegenerative disorder. The microbiota-gut-brain axis plays a crucial role in the development and progression of PD, and numerous studies have demonstrated the potential therapeutic benefits of modulations in the intestinal microbiota. This review provides insights into the characterization of the gut microbiota in patients with PD and highlights associations with clinical symptoms and underlying mechanisms. The discussion underscores the increased influence of the gut microbiota in the pathogenesis of PD. While the relationship is not fully elucidated, existing research demonstrates a strong correlation between changes in the composition of gut microbiota and disease development, and further investigation is warranted to explain the specific underlying mechanisms.

OBJECTIVES: To analyze the trends of disease burden of lip and oral cancers in East Asia from 1990 to 2021 and its future projections. METHODS: We used the Global Burden of Disease 2021 database to conduct a comprehensive analysis of disease burden data from China (including Taiwan Province of China), Japan, Republic of Korea, Democratic People's Republic of Korea and Mongolia. The data were stratified by age, gender and major risk factors, and a Bayesian age-period-cohort model was employed to predict the future trends. RESULTS: From 1990 to 2021, the burden of lip and oral cancers in East Asian countries exhibited a steady increase. Taiwan Province of China experienced the most significant increases in incidence, prevalence, mortality, and disability-adjusted life years (DALYs), while Mongolia saw a decline in both mortality and DALYs. In 2021, Taiwan Province of China reported the highest rates of lip and oral cancer incidence (27.50 per 100 000), prevalence (137.92 per 100 000), mortality (9.59 per 100 000), and DALYs (292.07 person-years per 100 000), particularly among male and elderly populations. Tobacco use and alcohol consumption significantly exacerbated the disease burden in Taiwan Province of China and Japan. Future projections indicate that the incidence and prevalence of lip and oral cancer in China (excluding Taiwan Province of China) will continue to rise, while their mortality rates are expected to decline in most regions, except for Taiwan Province of China and Democratic People's Republic of Korea. CONCLUSIONS By the year 2035, the disease burden of lip and oral cancers in East Asia is expected to continue to increase, especially in Taiwan Province of China. To address this challenge, it is essential to implement effective measures to control major risk factors, promote early screening, and ensure equitable distribution of healthcare resources.

Objective:To explore the relationship between psychological resilience,professional identity and employment pressure of nursing students with different educational levels,and analyze its influencing factors.Methods:A total of 208 nursing students with different educational levels were investigated by using the general information questionnaire,the employment pressure questionnaire of nursing students,the psychological resilience scale and the professional identity questionnaire.The correlation among psychological resilience,professional identity and employment stress was analyzed by Pearson correlation analysis.Results:The total score of professional identity,psychological resilience,and employment stress was(54.46±12.34),(57.62±18.66),and(98.30±20.25),respectively.There was no significant difference in professional identity score and psychological resilience score among nursing students with different educational levels(P＞0.05).There was no significant difference in the employment stress scores between nursing students upgrading from a junior college and undergraduate and junior college nursing students(P＞0.05),while the employment stress score of junior college nursing students were significantly higher than that of undergraduate nursing students(P＜0.05).Pearson correlation analysis showed that the total score of employment stress was positively correlated with the total score of psychological resilience(r=0.252),and the total score of professional identity(r=0.312)(P＜0.01).Conclusions:The psychological resilience of nursing students is at the average level,professional identity is low,and the employment pressure of junior college nursing students is higher than that of undergraduates.Targeted interventions should be developed to improve the psychological resilience and professional identity of nursing students,and reduce the employment pressure level of junior college nursing students.

Objective:To explore the current status and influencing factors of meaning in life among postoperative lung cancer patients, providing reference and guidance for the development of nursing interventions.Methods:From January to March 2023, convenience sampling was used to select 170 lung cancer patients with surgery in Department of Chest Surgery of the Cancer Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College as the study subject. The patients were surveyed using the General Information Questionnaire, Chinese version of Meaning in Life Questionnaire (C-MLQ), and the Cancer Fatigue Scale (CFS) .Results:The score of meaning in life among postoperative lung cancer patients was (45.71±5.90). Hierarchical linear regression analysis showed that living alone, educational level, and cancer-related fatigue were the influencing factors on the meaning in life among postoperative lung cancer patients ( P<0.05) . Conclusions:The meaning in life of postoperative lung cancer patients is at a moderate level. Medical and nursing staff should focus on patients who live alone and have a low level of education, and can also improve their meaning in life by alleviating cancer-related fatigue.

Objective To analyze the research trends and hotspots of tenecteplase and provide a reference for clinical research and rational drug use in China.Methods A comprehensive search was conducted on tenecteplase studies in the Web of Science database from its inception to April 2024.CiteSpace 6.1.R6 software was used to analysis authors,countries/regions,research institutions,keywords,and co-cited references.Results A total of 673 articles were included in this study.The annual publication volume showed an overall upward trend,rapidly increasing in the past three years.The United States,Canada,and Australia were the top 3 countries in terms of publication volume in this field.Among the top 10 institutions in publication volume,9 were from above 3 countries.The research hotspots were the efficacy and safety of tenecteplase in patients with acute myocardial infarction and acute ischemic stroke.In recent years,research hotspots have mainly focused on the field of acute ischemic stroke.Conclusion The application of tenecteplase in the field of acute ischemic stroke is currently a research hotspot.However,there is still a gap between the research level in China and that in developed countries such as the United States.Future research hotspots may still focus on the application of tenecteplase in patients with different types of acute ischemic stroke,suggesting that scholars should pay close attention to this area.

Objective:To analyze the results of the practice test and formal test of the annual professional proficiency test for residents in 2022, to investigate related influencing factors and the effectiveness of the practice test, and to propose the measures for improving the results of the annual professional proficiency test.Methods:The scores of the annual professional proficiency test were analyzed for 202 residents who participated in the test in 2022, and the data on sex, education background, type of personnel, whether they passed the medical licensing examination, and practice test scores were analyzed to investigate related influencing factors. SPSS 23.0 and GraphPad Prism 8 were used for the chi-square test, the t-test, the one-way of variance, and the Fisher's exact test. A multiple linear regression analysis was used to identify influencing factors, and a Pearson correlation analysis was also performed. Results:The scores of the annual professional proficiency test for 202 residents were normally distributed with the highest number of the residents with a score of 90-99 points and the lowest number of the residents with a score of <70 points. The residents who passed the medical licensing examination had a significantly higher score of the annual professional proficiency test than those who failed the examination ( t=2.87, P=0.005), and the residents who passed the three practice tests had a significantly higher score of the annual professional proficiency test than those who failed the practice tests ( P<0.05). The score of the second practice test, the score of the third practice test, and the passing of medical licensing examination were independent influencing factors for the score of annual professional proficiency test ( R2=0.236, R2=0.201, F=6.60, P<0.05). The correlation analysis showed that the scores of the three practice tests were positively correlated with the final score ( r=0.189, 0.373, and 0.311, P<0.05). Conclusions:Improving the passing rate of medical licensing examination and strengthening pre-examination practice tests can help to improve the score of annual professional proficiency test. At the same time, it is necessary to improve the quality of training through the measures such as strengthening the homogenization management of different types of students, improving the attention and enthusiasm of all levels, and accelerating the construction of question banks.

Objective:To understand the effect of standardized residency training for residents with different identity types, and put forward targeted optimization and improvement measures to achieve the homogenization of training effect.Methods:Combined with literature review and expert consultation results, a self-designed questionnaire was conducted for 324 residents who completed their courses in 2019 and 2020. The effective recovery rate of the questionnaire was 87.65%. By comparing the passing rate of first-time medical admission and completion examination of different identity types, and the training standards of six core competencies, the training effect conclusion was drawn. T-test and Fisher exact probability test were also made by SPSS 21.0. Results:The passing rates of first-time doctors and completion examinations were higher in professional masters and units than in the general population, with the highest passing rates reaching 100% (10/10) and 97.3% (72/74) respectively. There was no statistical difference between the passing rates of residents with different identity types. The overall standard of the six core competencies of the integrated professional masters was better than that of the society and unit personnel. There were statistical differences between the groups in the training standards of the four abilities of the residents with different identity types in professional literacy ( P=0.048), patient management ( P=0.030), communication and cooperation ( P=0.026) and learning promotion ( P=0.003). There was no significant difference in professional ability ( P=0.131) and teaching ability ( P=0.061). Conclusion:There is no difference in the passing rate of residents with different identity types in a military hospital, which achieves the goal of homogenization training to a certain extent. However, there are obvious differences in the standards of the six core competencies, and further optimization measures need to be explored.

Objective:To construct the standardized preventive nursing training scheme for venous thromboembolism (VTE) , so as to provide a basis for hospitals to carry out the standardized preventive nursing training scheme for VTE.Methods:Under the guidance of the National Medical Quality and Safety Improvement Goal, the standardized preventive nursing training scheme for VTE was initially developed through preliminary investigation, literature review and group discussion.

【Objective】 To develop a prognosis model based on CT images using radiomics method for patients with osteonecrosis of the femoral head (ONFH) and to investigate the additional prediction value of the imaging features of the contralateral normal femoral head regions for the prognosis prediction. 【Methods】 A total of 51 patients were included in this retrospective study. All the patients had preoperative CT images. For each patient, two regions of interest (ROIs) were involved, including the osteonecrosis region and the contralateral normal femoral head region. A total of 968 radiomics features were extracted for each patient. We made both the univariate and multivariable analyses. Three models were developed based on the features of osteonecrosis region, contralateral normal femoral head region, and both regions. The 10 times of repeated random experiments were used for model construction and validation. The average performance of the 10 times of experiments was reported as the results. 【Results】 For the features of osteonecrosis region, 37 features showed significant predictive value, with the mean AUC value of 0.708 2±0.029 9. The AUC of the constructed prediction model was 0.911 0±0.029 4 and 0.688 6±0.089 3 for the training set and validation set, respectively. For the features of contralateral normal femoral head region, 14 features showed significant predictive value, with the mean AUC value of 0.703 6±0.006 9. The AUC value of the constructed model for the training set and validation set was 0.867 2±0.039 5 and 0.669 0±0.072 6, respectively. For the models developed based on combined features, the AUC value was higher than that of the models developed based on osteonecrosis region features (training set: 0.935 8±0.016 6 vs. validation set: 0.737 9±0.090 8). 【Conclusion】 We developed a novel CT images-based radiomics method to predict postoperative prognosis in patients with ONFH. Furthermore, the features of contralateral normal femoral head region has additional prediction value. Combining the imaging features of osteonecrosis region and contralateral normal femoral head region can obtain more accurate prediction of prognosis in patients with ONFH.
