Based on the analyses of the status of humanistic medicine education both at home and abroad, the article emphasized the need for the implement of medical humanities education with the whole process and multidisciplinary integration. In combination with practice, from the three modules of the ex-plicit curriculum, implicit curriculum and integrated curriculum, the author discussed the specific conno-tation of the whole course of medical humanities education. The article also summarized the main points of the course system in teaching practice from the aspects of training objectives, teaching staff construction, teaching methods improvement and innovation, and humanistic quality evaluation of medical students.

OBJECTIVETo investigate the effect of benzo[a] pyrene(BaP) on DNA damage and expression of genes involved in nucleotide excision repair[xeroderma pigmentosum group B, C, G(XPB, XPC, XPG) and excision repair cross-complementing 1 (ERCC1)] in lung cancer A549 cells.
METHODSCell survival was measured using MIT metabolic viability assay. Single cell gel assay was applied to determine the DNA damage and repair. The level of gene expression was measured by reverse transcription-polymerase chain reaction.
RESULTSThe cell survival decreased from 95.0% to 70.0% after 24 h treatment with BaP of varying concentration ranging 0.625-20.000 mumol/L. The cell survival decreased to 87.0% and 73.0% respectively after 12 h and 24 h treatment with 10 mumol/L BaP, with DNA damage gradually elevated. At 12 h after 24 h treatment, the cell survival further decreased to 59.0% and DNA damage became most serious. At 24 h after 24 h treatment, cell survival recovered to 71.0%, and damaged DNA was repaired gradually. XPB and XPC gene expression increased to 4.5-fold and 11.2-fold respectively compared with basal level at 24 h treatment or 12 h after 24 h treatment with 10 mumol/L BaP respectively. However, ERCC1 and XPG gene expression was inhibited in 24 h treatment period, then recovered gradually after treatment.
CONCLUSIONBenzo[a]pyrene could lead to DNA damage and expression level change of genes involved in nucleotide excision repair in lung cancer A549 cells.

Objective:To establish a set of scientific and reasonable indicator system of common prosperity in the field of health, so as to promote the construction and evaluation of the demonstration area of common prosperity with high quality of health.Methods:According to the requirements of promoting common prosperity demonstration area with high quality of health in Zhejiang province, the initial indicator pool was established through literature research and theoretical analysis in July 2021, and experts were convened to carry out expert brainstorming to determine indicator system in the form of meetings. Delphi method was used to conduct two rounds of expert consultation on the indicator system.Finally, the analytic hierarchy process and percentage weight method were used to calculate the indicator weight value.Results:The final indicator system included 4 first-level indicators and 30 second-level indicators. Among the first-level indicators, the weight values of the development, equilibrium, inclusiveness, and sustainability were 0.326 4, 0.242 8, 0.245 8, and 0.185 0. There were 8 second-level indicators in developmental indicator dimension, of which the indicator with the highest weight was the per capita health expectancy. The balance indicator dimension included 6 second-level indicators, of which the indicator with the highest weight was the per capita financing difference of basic medical insurance between the urban workers with the urban-rural residents. The inclusive indicator dimension included 6 second-level indicators, and the proportion of personal health expenditure to total health expenditure had the highest weight. The sustainability indicator dimension included 10 second-level indicators, and the proportion of government health expenditure in fiscal expenditure had the highest weight.Conclusions:The indicator system constructed in this research could provide certain guidance and reference for promoting the construction of common prosperity in health, and provide some reference for follow-up research in this field.

Objective:To investigate the normal range of exhaled nitric oxide (FeNO) in 6-18-year-old children in China, so as to provide a data base for the establishment of FeNO standards for Chinese children.Methods:A multi-center study was conducted on 5 949 children aged 6-18 (3 101 males and 2 848 females) in 16 pro-vinces of 7 administrative districts in China.According to the technical standard recommended by American Thoracic Society/European Respiratory Association, FeNO was measured, and the relationship of FeNO with the sex, age, height, weight, body mass index and region was discussed.Results:The geometric mean FeNO value of Chinese children aged 6-18 was 14.1 ppb, and its 95% confidence interval (skewness distribution) was 1.0-38.2 ppb.The geometric mean FeNO values of children aged 6-11 and 12-18 were 13.1 ppb and 15.7 ppb, respectively, and their 95% confidence intervals (skewness distribution) were 1.0-38.1 ppb and 2.0-38.2 ppb.For children at and under 11 years old, FeNO decreased with age, with a mean decline of 1 ppb per year.The multiple linear regression results suggested that there was a significant correlation between FeNO and age for children aged 6-11, and FeNO of children aged 12-18 was significantly correlated with the gender, height, and region(all P<0.01). Conclusions:FeNO values of Chinese children and adolescents in this study are higher than those obtained by the previous study conducted from 2010 to 2012.For children aged 12-18, 16 ppb is recommended as the clinical cut-off point.For children at or under 11 years old, the influence of age on FeNO should be considered, and the cut-off point of FeNO decreases by 1 ppb as the age is reduced by one year.
