BACKGROUND:Mitophagy is closely associated with the development of idiopathic pulmonary fibrosis,but its mechanism remains unclear.OBJECTIVE:To investigate the biological mechanism of mitophagy in idiopathic pulmonary fibrosis and provide ideas for the risk prediction of idiopathic pulmonary fibrosis and subtype differentiation.METHODS:The mitophagy-related genes in idiopathic pulmonary fibrosis were obtained through GEO and Reactome Pathway databases.The mitophagy-related characteristic genes in idiopathic pulmonary fibrosis were screened based on intergroup differences and random forest model.GO functional enrichment analysis and KEGG,Reactome with WIKI pathway enrichment analyses were performed by g:Profiler database.Mitophagy subtypes in idiopathic pulmonary fibrosis were distinguished by consensus clustering method and immune infiltration analysis was performed.The mitophagy-related key gene was screened.Finally,the predictive value of mitophagy-related key gene for the risk of idiopathic pulmonary fibrosis was quantified by alignment diagram and the correlation between mitophagy-related key gene and clinical characteristics of idiopathic pulmonary fibrosis was explored.RESULTS AND CONCLUSION:(1)A total of 13 genes related to mitophagy in idiopathic pulmonary fibrosis were identified and 5 characteristic genes were screened,containing PINK1,RPS27A,SRC,HIF1A,and CDH6.(2)GO analysis was mainly involved in ubiquitin protein ligase binding,and cellular response to hypoxia.Pathway enrichment analysis was mainly involved in PINK1-PRKN mediated mitophagy,NOTCH signaling pathway,signaling by EGFR and angiogenesis.(3)HIF1A had significant expression differences between subtypes,which might serve as a key gene for the differentiation of mitophagy subtypes of idiopathic pulmonary fibrosis.(4)Immune infiltration analysis suggested that myeloid-derived suppressor cell,neutrophil and type 1 T helper cell might have infiltration differences between subtypes,while HIF1A was positively correlated with multiple immune cells.(5)Alignment diagram suggested that the risk of idiopathic pulmonary fibrosis might be predicted by the expression level of HIF1A.(6)Clinical characteristics analysis indicated patients with high expression of HIF1A might have poorer lung function and more severe fibrosis.It is concluded that PINK1,RPS27A,SRC,HIF1A,and CDH6 may influence the development of idiopathic pulmonary fibrosis through mitophagy,in which HIF1A may serve as a key gene for risk prediction with clinical subtype differentiation and HIF1A is strongly associated with the lung function of patients.

Objective:To evaluate the effect of 5th generation mobile communication technology(5G) remote robot-assisted cholecystectomy on postoperative recovery and quality of life in patients with gallstones.Methods:Clinical data of patients who underwent 5G remote robotic cholecystectomy(20 cases) vs traditional robotic cholecystectomy(20 cases) at Gansu Provincial People's Hospital from May to September 2023 were retrospectively analyzed. Intraoperative and postoperative related indexes were compared between the two groups, and changes in pain analog scores before, 12 hours, and 24 hours after surgery, and global quality of life (GIQLI) scores before and 3 months after surgery were evaluated.Results:There was no significant difference between the two groups in terms of intraoperative and postoperative conditions (intraoperative blood loss, operative time, time to exhaustion, and length of hospital stay). Patients' pain analog scores at 12 and 24 hours postoperatively were lower than preoperatively, but the differences were not statistically significant( P>0.05). In addition, there was no significant difference in recovery indicators between the two groups compared to the control group ( P>0.05). Conclusion:The postoperative recovery metrics of 5G tele-robotic-assisted cholecystectomy were consistent with the results of conventional robotic surgery.

Objective:To develop a treatment-related quality of life scale for Chinese patients with multiple myeloma (MM) and to test its reliability and validity.Methods:The initial scale was constructed through a literature search, Delphi expert correspondence, and cognitive testing. This study conducted a preliminary survey of 379 patients with MM and a formal survey of 865 patients from the hematology departments of 155 hospitals nationwide from February 2024 to March 2024. The final scale was obtained after conducting item analysis and reliability and validity tests on the initial scale.Results:The constructed scale contains 36 items covering six domains: physiological, psychological, social, treatment side effects, general health, and others. In the preliminary survey, the Cronbach’s alpha coefficient of each item ranged from 0.597 to 0.939, and the test-retest reliability was 0.747 ( P<0.001). Exploratory factor analysis extracted eight common factors with a cumulative variance contribution of 60.058%. In the formal survey, the Cronbach’s alpha coefficient of each item ranged from 0.484 to 0.930, and the test-retest reliability was 0.835 ( P<0.001). Confirmatory factor analysis revealed a comparative fit index of 0.750, a root-mean-square error of approximation of 0.090, and a root-mean-square residual of 0.067. Conclusion:The treatment-related quality of life scale for Chinese patients with MM designed in this study exhibited good reliability and validity, reflecting the impact of treatment on the quality of life of patients. This scale can provide a reference to clinicians for assessing the disease status of patients.

Objective To analyze the current status of stroke treatment in the hierarchical medical service network and the impact of referral on prognosis,to optimize the stroke treatment models,and to improve stroke treatment efficiency.Methods Totally 573 patients with acute ischemic stroke who were referred by the hierarchical medical service network in Lishui,Zhejiang Province from January 2020 to December 2022 were selected for analysis of treatment and clinical data.Based on whether they received endovascular treatment at a high-level stroke center,they were divided into an effective referral group(261 cases)and an ineffective referral group(312 cases).Demographic data,influencing factors,clinical characteristics,and laboratory tests were compared between the two groups,and the differences were analyzed by using single-factor analysis,and prognosis of the two groups of patients was assessed.Results Among 573 patients,197 received intravenous thrombolytic therapy and 261 received intravascular therapy.The effective referral rate was 45.55％.The proportion of patients in the effective referral group coronary artery disease and atrial fibrillation proportion is higher(x2=5.34,8.67,P＜0.05),more likely to show dysarthria,gaze,and consciousness disorder(x2=130.1,22.12,22.96,P＜0.05),and the baseline NIHSS score was higher(F=3.25,P＜0.05).Comparing the baseline blood cells counts of the two groups of patients at admission,the effective referral group showed lower eosinophil count,basophil count and lymphocyte(Z=-8.86,-5.39,F=0.598,P＜0.05).As for the prognosis,the proportion of neurological function improvement at discharge in the effective referral group was higher than that in the ineffective referral group.Binary Logistic regression analysis showed that baseline NIHSS score(OR=1.122,95％CI:1.074-1.172),eosinophil(OR=0.085,95％CI:0.013-0.564),and neutrophil count(OR=1.088,95％CI:1.011-1.172)were independent influencing factors for effective referrals.Conclusions The efficiency of the current regional stroke classification and treatment network needs to be further improved.Developing predictive models that include demographic characteristics,risk factors,symptoms,signs,and laboratory tests may help medical staff in stroke prevention and treatment centers quickly identify large vessel occlusion and improve acute ischemic stroke treatment efficiency.

Objective:To investigate the short-term and long-term effects of competency-oriented BOPPPS combined with scenario simulation teaching model on team emergency rescue skills training for healthcare professionals in Xizang.Methods:Forty-four healthcare professionals who participated in team emergency rescue training at Bianba People's Hospital from May 2022 to May 2023 were selected as study subjects. The BOPPPS combined with scenario simulation teaching model was applied in the clinical teaching of acute myocardial infarction. Before the training, the post competency was assessed using the Self-Directed Learning Instrument. The short-term teaching effects were evaluated using skill assessment and questionnaire after the training, and the long-term teaching effects were evaluated using the same questionnaire after six months.Results:Post-training skill assessment scores of the trainees were (50.45±6.68) for skill operation, (7.80±0.97) for humanistic communication, and (16.28±1.52) for team cooperation, which were significantly higher than pre-training scores ( P<0.05). Among self-directed learning abilities, "I enjoy finding answers to questions" was positively correlated with the humanistic communication scores, and "I can connect new knowledge with my personal experiences" was negatively correlated with skill operation scores ( P<0.05). The score of long-term emergency rescue skill improvement (4.27) was significantly higher than that after the training in the short term (3.98) ( P<0.05), while there were no significant decreases in career confidence and team collaboration ability ( P>0.05). Conclusions:The post competency-oriented BOPPPS combined with scenario simulation teaching model contributes to improving the team emergency rescue skills of healthcare professionals in Xizang, stabilizing their career confidence, and stimulating their self-learning ability. It is suitable to promote this teaching model in the clinical skills training of healthcare professionals in Xizang.
