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 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.
