Sepsis-induced lung injury is a common type of sepsis complicated with multiple organ dysfunction syndrome， whose uncontrolled inflammatory response and oxidative stress are the key pathological mechanisms. As an important pathway of anti-inflammatory and anti-oxidative stress， the nuclear factor-erythroid 2-related factor 2 （Nrf2） signaling pathway is very important in the occurrence and development of sepsis-induced lung injury. This review summarizes relevant research conducted over the past decade on the regulation of the Nrf2 signaling pathway by traditional Chinese medicine （TCM） to ameliorate sepsis- induced lung injury. It has been found that 14 kinds of TCM effective ingredients （including five types of compounds： flavonoids， terpenes， alkaloids， saponins， phenols） and 6 kinds of compound preparations （including three types of formulas： heat-clearing and detoxifying formulas， purgative formulas for promoting bowel movement， and formulas for reinforcing vital qi and consolidating the constitution） can inhibit inflammatory responses and oxidative stress by activating Nrf2 signaling pathway and intervening in related pathways such as those involving Kelch-like ECH-associated protein 1， heme oxygenase-1， antioxidant response element and AMP-activated protein kinase， thereby alleviating sepsis-induced lung injury.

The aryl hydrocarbon receptor (AhR) plays a crucial role in regulating many physiological processes. Activating the AhR-CYP1A1 axis has emerged as a novel therapeutic strategy against various inflammatory diseases. Here, a practical in situ cell-based fluorometric assay was constructed to screen AhR-CYP1A1 axis modulators, via functional sensing of CYP1A1 activities in live cells. Firstly, a cell-permeable, isoform-specific enzyme-activable fluorogenic substrate for CYP1A1 was rationally constructed for in-situ visualizing the dynamic changes of CYP1A1 function in living systems, which was subsequently used for discovering the efficacious modulators of the AhR-CYP1A1 axis. Following screening of a compound library, LAC-7 was identified as an efficacious activator of the AhR-CYP1A1 axis, which dose-dependently up-regulated the expression levels of both CYP1A1 and AhR in multiple cell lines. LAC-7 also suppressed macrophage M1 polarization and reduced the levels of inflammatory factors in LPS-induced bone marrow-derived macrophages. Animal tests showed that LAC-7 could significantly mitigate DSS-induced ulcerative colitis and LPS-induced acute lung injury in mice, and markedly reduced the levels of multiple inflammatory factors. Collectively, an optimized fluorometric cell-based assay was devised for in situ functional imaging of CYP1A1 activities in living systems, which strongly facilitated the discovery of efficacious modulators of the AhR-CYP1A1 axis as novel anti-inflammatory agents.

Objective:To understand the epidemiological characteristics and trends of injury in older adults in Jiangsu Province from 2006 to 2022 and provide a scientific basis for developing prevention and control measures.Methods:The data on injury cases aged 60 and older were collected from 12 sentinel hospitals in Jiangsu Province during 2006-2022. The study analyzed the proportion of injury cases among the elderly in the overall population and calculated the annual percent change and average annual percent change (AAPC). A pairwise comparison between groups was performed, and the differences were judged according to the adjusted standardized residuals.Results:From 2006 to 2022, there were 218 426 injury cases among individuals aged 60 and older in Jiangsu Province, which accounted for an increasing proportion of injury cases within the entire population (AAPC=3.17%, P<0.001). The first five causes of elderly injury were falls (42.06%), road traffic injuries (20.20%), animal injuries (11.45%), knife/sharp injuries (9.43%), and blunt injuries (8.13%). From 2006 to 2022, the proportion of falls, animal injuries, and knife/sharp injuries among the elderly aged ≥60 showed an increasing trend, while the proportion of road traffic injuries and blunt injuries decreased (all P<0.001). The incidence of injury was highest in October, with a daily incidence peak between 8:00 and 10:00. Leisure activities (40.34%) were the major activity leading to injury. The injury occurred mainly at home (53.74%), and the injury intention was mainly unintentional (97.41%), all of which showed an increasing trend ( P<0.001). The injuries were mainly bruises (36.00%), and the most common injured positions of the body were low limbs (27.55%), all of which showed a decreasing trend ( P<0.001). About 69.80% of cases were slight, and 79.38% were discharged after treatment, which showed an increasing trend ( P<0.001). Conclusions:The injury data for individuals aged 60 and older in Jiangsu Province exhibited varying trends from 2006 to 2022. There was a noticeable increase in the proportion of elderly injury cases within the overall injury population, as well as an upward trend in falls, animal injuries, and knife/sharp injuries as leading causes of injury. It is imperative to actively develop prevention measures based on the epidemiological characteristics and evolving trends of elderly injuries in Jiangsu Province.

Objective To quantitatively analyze the effects of population aging and other risk factors on the burden of colorectal cancer in China from 1990 to 2019. Methods The Global Burden of Disease Study 2019 was used to describe the temporal trend of the burden of colorectal cancer. A decomposition method established by Gupta was applied to quantify the burden related to population growth, aging, age-specific prevalence, and disease severity. Results The age-standardized disability adjusted life years (DALY) rates of colorectal cancer in China showed an overall upward trend from 1990 to 2019. The DALY in 2019 increased by 191.12% compared with that in 1990, with 34.54% of the increase attributed to population growth, 111.36% to population aging, and 77.56% to the rise of age-specific prevalence. Meanwhile, -32.54% benefited from the changes in disease severity. Diet low in milk was the primary risk factor for the disease burden of colorectal cancer in China in 2019, followed by diet low in whole grains and calcium. In the last 30 years, the corresponding risk factor of the most rapid increase in China was high BMI with an average annual percentage of change of 4.14%, and the corresponding risk factor of the most rapid decrease in China was diet low in fiber with an average annual percentage of change of -2.00%. Conclusion Aging population is mainly responsible for the considerable increase in the burden of colorectal cancer in China from 1990 to 2019. The health administrative authorities should take corresponding measures to address the adverse impacts associated with aging.

Conclusions:The scheme constructed in this study is scientific and operable and comprehensively reflects the comprehensive management strategy from three aspects, which is worthy of clinical application.

Objective: To investigate the intake of liquid dairy products and identify its influencing factors among the fourth grade students in Nanjing City. Methods: The fourth grade students were selected as the study subjects in Nanjing City using a multi-stage random cluster sampling method in September 2020. Their general information, frequency of liquid dairy product intake one week prior to survey and mean intake amount per time were collected. According to the 2016 Dietary Guidelines for Chinese Residents, weekly intake of liquid dairy products of 2 100 g and greater was defined eligible. Factors affecting the frequency and amount of liquid dairy product intake were identified using multivariable logistic regression analysis. Results: A total of 2 268 questionnaires were allocated and 2 216 valid questionnaires were recovered, with an effective recovery rate of 97.71%. The respondents included 1 199 boys ( 54.11% ) and 1 017 girls ( 45.89% ). The frequency of liquid dairy product intake was (6.41±4.86) times per week, and the median intake amount was 1 250.00 g per week (interquartile range, 1 750.00 g per week). There were 607 students ( 27.39% ) consuming liquid dairy products of 2 100 g and greater a week, and 1 016 students ( 45.85% ) consumed liquid dairy products for 7 times and more a week. Multivariable logistic regression analysis showed that living in urban areas ( OR=1.204, 95%CI: 1.005-1.443 ), knowing nutrition labels ( OR=1.221, 95%CI: 1.021-1.460 ), periodical measurement of body weight (OR=1.486, 95%CI: 1.098-2.011) and restricted intake of sugar-containing drinks ( OR=1.264, 95%CI: 1.005-1.590 ) facilitated the intake of liquid dairy products for 7 times and more a week, and students with periodical measurement of body weight were more likely to consume liquid dairy products for 2 100 g and greater a week ( OR=1.821, 95%CI: 1.240-2.676 ). Conclusions Inadequate intake of liquid dairy products is found among the fourth grade students in Nanjing City. Residence, awareness of nutrition labels, periodical measurement of body weight, and parental restriction of sugar-containing drink intake affect the intake of liquid dairy products.

Objective:To investigate the joint associations of smoking and insufficient physical activity with hypertension, diabetes and dyslipidemia in male adults.Methods:Based on the data from the 2017 Nanjing Chronic Diseases Risk Factors Surveillance Program, 61 098 Nanjing residents aged 18 and older was randomly recruited from 12 districts, using the multi-stage stratified cluster sampling method. Information about smoking behaviors, physical activity and chronic disease-related indicators within the first 12 months before the survey was obtained through questionnaires.Results:Among the 29 848 valid male samples, the proportions of non-smokers, current smokers and ex-smokers were 59.6%, 37.2% and 3.2%, and the proportions of those who had physically active<600 MET-min/w (insufficient physically active) and ≥600 MET-min/w (adequate physically active) were 18.8% and 82.2%, respectively. In non-smokers, current smokers and ex-smokers, the prevalence of hypertension was 24.7%, 34.0% and 43.8%, and the prevalence of diabetes was 8.8%, 12.3% and 16.5%, and the prevalence of dyslipidemia was 26.8%, 36.1% and 41.9%, respectively. Multivariate logistic regression analysis showed that current smokers had a higher risk of hypertension ( OR=1.164, 95% CI: 1.086-1.248), diabetes ( OR=1.324, 95% CI: 1.207-1.452), and dyslipidemia ( OR=1.291, 95% CI: 1.216-1.371) than non-smokers in male adults. Compared with people who had adequate physical activity, someone with insufficient physical activity had higher hypertension ( OR=1.452, 95% CI: 1.331-1.583), diabetes ( OR=1.170, 95% CI: 1.041-1.315) and dyslipidemia ( OR=1.245, 95% CI: 1.158-1.338). And current smokers with insufficient physical activity had the highest risk of hypertension ( OR=1.749, 95% CI: 1.550-1.974), diabetes ( OR=1.363, 95% CI: 1.165-1.595), and dyslipidemia ( OR=1.614, 95% CI: 1.461-1.782) in male adults. Conclusions:Smoking and insufficient physical activity are risk factors for hypertension, diabetes, and dyslipidemia. People who is characterized by smoking together with insufficient physical activity presents with increased risk on developing hypertension, diabetes, and dyslipidemia.

Objective:To explore the association between different paths of diabetic progression and dyslipidemia in a Nanjing adult population.Methods:From January 2017 to June 2018, 61, 098 local residents aged ≥18 years were selected from the Chronic Disease and Risk Factor Surveillance database in Nanjing using a five-stage stratified cluster random sampling method. Data were collected through interview surveys, physical measurements, and laboratory examinations. The relationship between different rates of diabetic progression and dyslipidemia was analyzed using complex weighting and multilevel models.Results:In all, 60, 283 participants were finally enrolled in the study. The weighted proportions of normal glucose regulation, pre-diabetes, and diabetes were 71.2%, 17.9%, and 10.9%, respectively. The overall weighted prevalence, awareness, treatment, and control of dyslipidemia were 29.8%, 41.6%, 28.9%, and 22.9%, respectively. The weighted proportion of patients with dyslipidemia combined with diabetes was 52.9%. The weighted prevalence of dyslipidemia in adults with normal glucose regulation, pre-diabetes, and diabetes was 24.0%, 38.8%, and 52.9%, respectively (all P<0.001). Compared to the normal glucose regulation group, subjects with pre-diabetes ( OR = 2.04, 95% CI: 1.95-2.13) or diabetes ( OR= 3.87, 95% CI: 3.66-4.10) had possibly gradually increased risks of dyslipidemia (all P<0.001). In addition, there was an increasing trend toward awareness, treatment, and control of dyslipidemia with increasing levels of glucose (all P<0.001). The weighted awareness of dyslipidemia in adults with normal glucose regulation, pre-diabetes, and diabetes was 36.3%, 42.8%, and 56.2%, respectively; the corresponding rates of treatment and control were 23.7%, 29.2%, and 43.7%, and 20.4%, 22.6%, and 30.1%, respectively. Conclusion:Diabetes and dyslipidemia have become the main chronic diseases in the Nanjing population.

Objective: To explore the knowledge and consumption of sugar sweetened beverage(SSB) and its influencing factors among third grade primary students, to provide basis for take targeted intervention measures. Methods: In September 2019, 1 686 primary school students of grade 3 were randomly selected from 2 primary schools in 1 urban area and 1 outer suburb area of 12 districts in Nanjing by using a multistage cluster sampling method，and a self administered questionnaire were offered to them to collect the knowledge about sugar sweetened beverage and its intake. Results: Totally 753 students (44.7%) answered 6 or more SSB knowledge questions correctly, and the rate of 389 students (50.2%) in urban areas was higher than that of 364 students (40.0%) in suburban areas. There were 780 (46.3%) students who knew that dairy containing beverage could not replace milk, the rate of 403 (52.0%) students in urban area was higher than that of 377 (41.4%) students in suburban area (χ 2=17.76, 18.99, P<0.05). Logistic regression analysis showed that compared with the frequency of consumption of SSB <1 time per week, the behavioral risk factors of primary school students who drink SSB ≥4 times per week were:urban area (OR=1.55), low parents educational level (OR=2.44), and frequent storage of SSB at home (OR=1.62). The protective factors were as follows:duration of extracurricular physical activity <120 min/week (OR=0.68), video time <120 min/day (OR=0.50), awareness rate of SSB ≥60% (OR=0.75), and restriction of high sugar snacks by parents (OR=0.60). Conclusion The knowledge associated with SSB among third grade students in Nanjing is relatively low. Consumption of SSB has been influenced by areas, parents educational level, knowledge about SSB and family factors. SSB consumption among primary students should be interfered at the school and family level. The health food education need to carry out based on the school and family, so as to create a supportive atmosphere integrating the school family to drink less sugar beverages.
