The life view of "human life is the most important" in Traditional Chinese Medicine (TCM) originates from the people-oriented theory of Chinese traditional culture, the benevolence thought of Confucianism, the rebirth thought of Taoism and the compassion thought of Buddhism. Taking the life view of "human life is the most important" as the starting point, it has formed medical ethics thoughts such as the social responsibility of saving the world, the medical practice purpose of treating all patients equally, the meticulous working attitude, the diligent and tireless learning attitude, and the exploration spirit of widely exploring the medical roots, which still has important educational significance. Therefore, the life view of "human life is the most important" should be integrated into the medical ethics education of medical students, and the medical ethics literacy of medical students should be improved through the following ways: strengthen the vocational ideal education of saving the dying and healing the wounded, and enhance the sense of social responsibility of medical students; consolidate the theme of life first classroom education and improve the professional identity of medical students; enrich and innovate the practice forms of protecting life, pay attention to the practicality of medical ethics education.

Objective To investigate the current postoperative physical activity levels of lung cancer patients after a month and to analyze the influencing factors.Methods From January to December 2023,a total of 1,195 lung cancer patients from 16 hospitals in eastem,central and westem China were selected as the survey subjects by the convenient sampling method.A cross-sectional survey was conducted by General Information Questionnaires,Health-Related Physical Fitness Surveys,MD Anderson Symptom Inventory,Hospital Anxiety and Depression Scale,Social Support Rating Scale,Self-Rated Abilities for Health Practices Scale,and the International Physical Activity Questionnaire.Results 36 questionnaires with missing data exceeding 10％and 13 duplicate questionnaires were excluded,resulting in the analysis of 1,146 questionnaires.After a month postoperatively,lung cancer patients with moderate and low levels of physical activity were 732(63.9％)and 204(17.8％),respectively.Multivariate regression analysis showed that the influencing factors included residence,average monthly family income,regional lymph node staging,family history of lung cancer,grip strength,hemoglobin,and depression score(P＜0.05).Conclusion The physical activity level of lung cancer patients a month after surgery is influenced by a combination of sociodemographic,disease-related,health-related physical fitness,and psychological factors.Clinical healthcare professionals should accurately assess the physical activity levels of lung cancer patients,identify those with insufficient physical activity,and develop and implement personalized intervention strategies based on their physical condition and potential influencing factors to enhance their physical activity levels and improve their quality of life.

Objective To investigate the application value of point-of-care lung ultrasound (POC-LUS) scoring in selecting respiratory support treatment modalities for neonatal infectious pneumonia (NIP). Methods A total of 89 NIP patients were selected as the study subjects and divided into control group (no assisted ventilation) with 46 cases, noninvasive group (noninvasive assisted ventilation) with 28 cases, and invasive group (invasive mechanical ventilation) with 15 cases based on the degree of dyspnea and blood gas analysis results. The POC-LUS scores of the three groups were compared, and the correlations of POC-LUS scores with arterial oxygen partial pressure [p_a(O₂)] and arterial carbon dioxide partial pressure [p_a(CO₂)] were analyzed. Receiver operating characteristic (ROC) curves were plotted to assess the predictive efficacy of POC-LUS scores for the need for noninvasive assisted ventilation or invasive mechanical ventilation in NIP patients. Results The POC-LUS scores of the noninvasive group and the invasive group were (31.7±7.3) and (42.1±8.0), respectively, which were higher than (21.5±7.3) of the control group. Additionally, the score of the invasive group was higher than that of the noninvasive group (P < 0.05). Correlation analysis revealed a significant negative correlation between POC-LUS scores and p_a(O₂) (r=-0.802, P < 0.05), and a significant positive correlation with p_a(CO₂) (r=0.807, P < 0.05). ROC curve analysis showed that the area under the curve (AUC) of POC-LUS scores for predicting the need for noninvasive assisted ventilation and invasive mechanical ventilation were 0.918 (95%CI, 0.862 to 0.973) and 0.938 (95%CI, 0.889 to 0.987), respectively. The sensitivity was 0.767 and 0.933, and the specificity was 0.935 and 0.824, with optimal cutoff values of 29.5 and 31.5, respectively. Conclusion POC-LUS scoring can quantitatively assess the severity of lung lesions in NIP patients and serves as a guiding tool for clinicians in selecting assisted ventilation treatment modalities.

Objective:To study the role of myocardial work parameters in early identification of myocardial injury in neonatal asphyxia.Methods:From July 2020 to December 2021, neonates diagnosed with mild neonatal asphyxia admitted to the Department of Neonatology of our hospital within 24 h after birth were prospectively enrolled into the asphyxia group. Neonates without asphyxia during the same period were selected as the control group and matched with the asphyxia group for gender, gestational age and birth weight at a ratio of 1:1~1:2. The asphyxia group was subgrouped into preterm asphyxia group and term asphyxia group. All neonates received echocardiography within 24 h after birth. Multiple parameters were measured including M-mode, two-dimensional image, Doppler image, global longitudinal strain (GLS) and myocardial work parameters [global work index (GWI), global constructive work (GCW), global wasted work (GWW), global work efficiency (GWE)]. The level of serum N-terminal pro brain natriuretic peptide (NT-proBNP) was recorded in the asphyxia group. The data were compared between the asphyxia group and the control group. Correlations between myocardial work parameters and other parameters were analyzed.Results:A total of 33 cases were in the asphyxia group and 43 cases were in the control group. The preterm asphyxia group (18 cases) showed significantly lower GWI and GCW than the preterm control group (18 cases) [GWI: (702±153) mmHg vs. (879±205) mmHg, GCW: (1 016±221) mmHg vs. (1 200±271) mmHg] ( P<0.05). No differences existed in GLS, GWW and GWE. The term asphyxia group (15 cases) showed significantly lower GWW than the term control group (25 cases) [45.0 (30.0, 65.0) mmHg vs. 71.0 (35.5,85.5) mmHg] ( P<0.05). No differences existed in GLS, GWI, GCW and GWE. GWI was negatively correlated with serum NT-proBNP level ( r=-0.327, P<0.05). Conclusions:GWI and GCW may indicate myocardial injury in preterm neonates with mild asphyxia.

Objective:To assess the impact of the general education course entitled " The Basics of Radiation Protection" on enhancing undergraduates′ awareness of radiation safety, a questionnaire was utilized. Additionally, this study aims to propose novel strategies for improving health literacy among undergraduates, fostering the development of innovative, talented individuals with reasonable knowledge structures and strong practical abilities.Methods:From 2021 to 2022, 127 undergraduates from all colleges of Shandong University took the general course" The Basics of Radiation Protection". To compare the learning effects of the medical and non-medical students, invitations to participate in this study were extended to 101 (79.5%) students from School of Medicine and School of Electrical Engineering. A questionnaire survey was conducted to determine and compare the changes in the students’ basic cognition of radiation safety and protection before and after learning the course. The aim was to evaluate the teaching effectiveness and significance of the course.Results:From 2021 to 2022, 94 undergraduates from School of Medicine and School of Electrical Engineering accepted the invitation and voluntarily completed questionnaires twicely, accounting for 74.0% of the total number of selected students. The questionnaire survey showed that through course learning, the cognitive level of radiation protection among college students had significantly improved. The Likert quantification scores befroe taking the course were 3.59±1.35, 3.81±1.17, 3.45±1.16, 4.11±1.13, 3.62±1.05, 3.98±1.24 and after completing the course 4.94±0.32, 4.87±0.32, 4.96±0.21, 4.98±0.15, 4.81±0.39, 4.98±0.15, respectively, with the difference being statistically significant ( t=6.55, 5.50, 9.10, 5.36, 7.60, 5.34, P< 0.05). Further analysis revealed that different professional backgrounds affected students′ understanding of radiation safety and protection: before learning this course, medical students were superior to electrical engineering students in their knowledge of ionizing radiation ( t=5.69, 4.06, 6.46, 6.27, 7.78, P < 0.001). After taking the course, the cognitive level of students from both majors had considerably improved, but there was no significant difference ( P> 0.05). Feedback on the course learning showed that the awareness of " routine radiation protection" had significantly improved (96.8%), pseudoscience and pseudoinformation could be identified (93.6%), " nuclear power" -related fears had been dispelled (95.7%), and the concept of " cherishing life" had been effectively established (91.5%). Conclusions:The general education course " The Basics of Radiation Protection" has effectively improved the students′ awareness of radiation safety, strengthened their knowledge regarding radiation safety and protection, and provided a new avenue for cultivating innovative talents on a well-structured knowledge base. The course would be worth further promoting and applying in the education of undergraduates with different backgrounds and taking different majors.

Objective:To study the regulatory effects of transforming growth factor beta-activated kinase 1 (TAK1) on microglia pyroptosis in hypoxic-ischemic brain damage (HIBD).Methods:Primary microglia cells were isolated from fetal mice and randomly assigned into 4 groups: the control group, 5z-7-oxozeaneol (5z-7) group, oxygen-glucose deprivation (OGD) group and OGD+5z-7 group. OGD models of microglia cells were established for the OGD groups and 5z-7 groups received a small molecule TAK1 inhibitor 5z-7. Expression of phosphorylated TAK1(P-TAK1), pyroptosis related proteins including NOD-like receptor pyrin domain containing 3 (NLRP-3), apoptosis-associated speck-like protein containing a CARD (ASC) oligomers, N terminal of Gasdermin D (GSDMD-N) and interleukin 1β (IL-1β) were examined using Western blot at 0 h, 6 h and 24 h after intervention. Lactate dehydrogenase (LDH) test and transmission electron microscope were used for pyroptosis evaluation.Results:(1) Compared with the control group, expressions of all proteins including P-TAK1, NLRP-3, ASC oligomers, GSDMD-N, IL-1β and LDH level showed no significant differences in the OGD group at 0 h ( P>0.05). P-TAK1 levels in OGD group at 6 h and 24 h were lower than the control group and the levels of NLRP-3, ASC oligomers, GSDMD-N, IL-1β and LDH were significantly higher ( P<0.05). Microglia pyroptosis (characterized by disruption of cell membrane, extravasation of cytoplasm and chromatin margin aggregation) was observed under electron microscope. (2) 5z-7 group and OGD+5z-7 group had lower P-TAK1 levels and higher NLRP-3, ASC oligomers, GSDMD-N, IL-1β and LDH levels than the control group and OGD group at 6 h and 24 h. Conclusions:The down-regulation of TAK1 phosphorylation level may promote microglia pyroptosis in HIBD. This regulatory effects is related to the up-regulation of NLRP-3 expression and the oligomerization of ASC.
