The resident standardized training is an important stage in clinical medical personnel training sys-tem. Medical ethics education and accomplishment is one of the main training contents in this stage is, the necessa-ry requirement for physician growth, and the effective guarantee for training organization and implementation. Learning for relevant theory of medical ethics is the basis of medical ethics education, and the medical practice is the fundamental way of medical ethics accomplishment. In medical practice, the inner perception is the gradual sublimation of medical ethics accomplishment. The formation of residents′ medical ethics quality is dominated by heteronomy and guided by medical morality code. It emphasizes more on self-regulating the ethical behaviors and abiding by medical ethics faith and standards.

Objective:To explore the relationship between lipid accumulation product (LAP) and disease activity, nutritional status in patients with Crohn disease (CD).Methods:The clinical data of 74 patients with CD in the Affiliated Hospital of Yangzhou University from July 2020 to June 2021 were retrospectively analyzed. The patients were divided into active group (32 cases) and remission group (42 cases) according to simplified Crohn disease activity index (CDAI). The general clinical data, laboratory examination results and body fat indexes were recorded, body fat indexes including body mass index (BMI), waist circumference, waist-to-height ratio, LAP and nutritional risk screening 2002 (NRS2002) score. Spearman method was used for correlation analysis; the receiver operating characteristic (ROC) curve was drawn to analyze the efficacy of LAP in predicting the disease activity and nutritional status in patients with CD.Results:The proportion of males, body weight, hemoglobin, albumin, total cholesterol, triglyceride and high-density lipoprotein cholesterol in active group were significantly lower than those in remission group: 46.9% (15/32) vs. 71.4% (30/42), (53.58 ± 8.13) kg vs. (61.05 ± 9.38) kg, (109.94 ± 23.70) g/L vs. (134.19 ± 18.03) g/L, (34.01 ± 5.71) g/L vs. (39.15 ± 4.27) g/L, (3.23 ± 0.68) mmol/L vs. (3.66 ± 0.74) mmol/L, (1.12 ± 0.36) mmol/L vs. (1.34 ± 0.55) mmol/L and (0.91 ± 0.23) mmol/L vs. (1.04 ± 0.33) mmol/L, the nutritional risk rate, platelet count, C-reactive protein and erythrocyte sedimentation rate were significantly higher than those in remission group: 68.8% (22/32) vs. 19.0% (8/42), (317.97 ± 130.19) ×10 9/L vs. (194.00 ± 51.91) × 10 9/L, 14.15 (6.15, 41.35) mg/L vs. 1.51 (0.22, 5.58) mg/L and 40.00 (20.50, 64.25) mm/1 h vs. 9.00 (3.00, 20.00) mm/1 h, and there were statistical differences ( P<0.01 or <0.05); there were no statistical difference in age, height, total protein and low-density lipoprotein cholesterol between the two groups ( P>0.05). The BMI, waist circumference, waist-to-height ratio and LAP in active group were significantly lower than those in remission group: 19.46 (17.70, 21.45) kg/m 2 vs. 21.08 (18.87, 23.12) kg/m 2, (72.51 ± 5.92) cm vs. (77.67 ± 7.27) cm, 0.44 ± 0.03 vs. 0.46 ± 0.04, 13.42 (5.07, 17.72) cm·mmol/L vs. 15.49 (9.37, 31.71) cm·mmol/L, the NRS2002 was significantly higher than that in remission group: 3.00 (1.00, 3.75) scores vs. 1.00 (0, 2.00) scores, and there were statistical differences ( P<0.01 or <0.05). Spearman correlation analysis result showed that LAP was positively correlated with BMI, waist circumference and waist-to-height ratio ( r = 0.701, 0.766 and 0.829; P<0.01); LAP was negatively correlated with NRS2002 score, platelet count and erythrocyte sedimentation rate ( r =- 0.609, - 0.249 and - 0.243; P<0.01 or<0.05). ROC curve analysis result showed that the areas under the curve of LAP predicting disease remission and nutritional status improvement in patients with CD were 0.645 and 0.832 (95% CI 0.520 to 0.770 and 0.739 to 0.925), the best cut-off values were 20.89 and 12.86 cm·mmol/L, the sensitivities were 45.2% and 81.8%, and the specificities were 87.5% and 73.3%. Conclusions:LAP has good predictive value for disease remission and nutritional status improvement in patients with CD.

Objective:To analyze the factors influencing the theoretical score of graduation examination of standardized residency training in a class-A tertiary general hospital in Shanghai from 2018 to 2021, and establish prediction models, and to provide a reference for further improving the quality of residency training.Methods:We collected the data of 556 residents who participated in the residency training graduation examination at the hospital from 2018 to 2021. Binary regression and logistic regression analyses were used to determine the association of residents' basic information, their routine assessment results at the bases, and the base performance assessment score (indicating the bases' training quality) with theoretical graduation examination results; and prediction models for the theoretical graduation examination score were established, using binary regression and logistic regression methods to construct model datasets. SPSS 26.0 was used for statistical analysis.Results:From 2018 to 2021, a total of 556 people participated in the residency training graduation examination at the hospital. The first-time pass rate of the first station theoretical examination station was 97.48% (542/556). Trainees graduating from double first-class schools had the highest first-time pass rate of 98.09% (359/366); doctoral students had the highest first-time pass rate of 98.59% (140/142); and residents of the two-year training program had the highest first-time pass rate of 98.34% (297/302). According to the binary regression analysis of categorical variables such as residents' basic information, the base level was associated with whether residents passed the theoretical examination ( P<0.05). According to the logistic regression analysis of residents' routine assessment scores and the base performance assessment score, the annual theoretical assessment score, the first-time theoretical score of the national medical licensing examination, the annual professional performance test score, and the base performance assessment score were key factors affecting the theoretical graduation examination score ( P<0.05). In the regression analysis associated with the theoretical graduation examination score, the annual professional performance test score showed the highest regression coefficient and the highest variance inflation factor, indicating strong multicollinearity. Therefore, the annual professional performance test score was important in predicting the theoretical score of the graduation examination. Conclusions:This study used binary regression and logistic regression models to analyze the possible factors affecting the theoretical graduation examination score and the degree of association, and also established two prediction models of the theoretical graduation examination score to predict trainees at risk. Through implementing the concept of hierarchical progression, adding personalized tutoring, realizing information management for residency training, and providing intelligent early intervention, the pass rate of residency training graduation examination is expected to be further improved, ultimately achieving the purpose of improving the quality of residency training.

Objective To explore the correlations of lumbar bone mineral density(BMD)and metabolic syndrome(MS)in adult males.Methods Data of low dose chest CT and quantitative CT of 13 490 adult males were retrospectively analyzed,and lumbar BMD were measured to judge whether MS existed and the degree of MS,and the correlations of lumbar BMD with MS or not and the degree of MS,as well as of lumbar BMD value and the related indicators of MS were assessed.Taken lumbar BMD as the dependent variable,the age,low density lipoprotein cholesterol(LDL-C),blood uric acid(BUA),hemoglobin(Hb)and MS or not were included in multiple linear regression analysis to observe the impact of MS and related indicators on lumbar BMD.Results Among 13 490 adult males,3 900 were found with MS(MS group),while 9 590 were found without MS(non-MS group).Significant difference of lumbar BMD was detected between groups(P=0.001).Lumbar BMD values were negatively correlated with MS(rs=-0.025,P=0.004)and the degree of MS(rs=-0.038,P＜0.001),whereas positively correlated with abdominal obesity,high triglyceride and low HDL-C or not(rs=0.024,0.061,0.036,all P＜0.001)but negatively correlated with hypertension and hyperglycemia or not(rs=-0.135,-0.104,both P＜0.05).After adjustment of age,lumbar BMD of adult males was negatively correlated with MS or not as well as LDL-C(both P＜0.05),but positively correlated with BUA and Hb(both P＜0.001).Conclusion Lumbar BMD was associated with MS in adult males.

Objective: To explore the influencing factors of abnormal pulmonary function in dust-exposed workers and establish the risk prediction model of abnormal pulmonary function. Methods: In April 2021, a total of 4255 dust exposed workers from 47 enterprises in 2020 were included in the study. logistic regression was used to analyze the influencing factors of abnormal pulmonary function in dust-exposed workers, and the corresponding nomogram prediction model was established. The model was evaluated by ROC curve, Calibrationpolt and decision analysis curve. Results: logistic regression analysis showed that age (OR=1.03, 95%CI=1.02~1.05, P<0.001) , physical examination type (OR=4.52, 95%CI=1.69~12.10, P=0.003) , dust type (Comparison with coal dust, Cement dust, OR=3.45, 95%CI=1.45~8.18, P=0.005, Silica dust (OR=2.25, 95%CI=1.01~5.03, P=0.049) , blood pressure (OR=1.63, 95%CI=1.22~2.18, P=0.001) , creatinine (OR=0.08, 95%CI=0.05~0.12, P<0.001) , daily exposure time (OR=1.06, 95%CI=1.10~1.12, P=0.034) and total dust concentration (OR=1.29, 95%CI=1.08~1.54, P=0.005) were the influencing factors of abnormal pulmonary function. The area under the ROC curve of risk prediction nomogram model was 0.764. The results of decision analysis curve showed that the nomogram model had reference value in the prevention and intervention of abnormal pulmonary function when the threshold probability exceeded 0.05. Conclusion: The accuracy ofthe nomogram model constructed by logistic regression werewell in predicting the risk of abnormal lung function of dust-exposed workers.
