Monotropein is a compound classified into iridoid which is found in herbaceous plants Morindae officinalis. It possesses anti-inflammatory, antioxidant, and anti-osteoarthritic activities. Previous study indicates that monotropein may have the potential to combat cardiovascular disease, although the related mechanism remains unclear. In this study, we constructed the model of atherosclerosis by oxidized low density lipoprotein-induced vascular smooth muscle cells and LDLR –/–mice given high-fat diet to investigate the effects of monotropein on atherosclerosis.Our results showed that monotropein treatment significantly reduced the area of atherosclerotic plaques and necrotic cores in mice, inhibited the proliferation and migration of vascular smooth muscle cells, and reduced inflammatory responses and oxidative stress, which in turn alleviated atherosclerosis. In addition, we found that monotropein reduced the expression levels of P-NF-κB and P-AP-1. In conclusion, our data suggest that monotropein inhibited the proliferation and migration of vascular smooth muscle cells by mediating the activity of NF-κB, AP-1, reducing the level of inflammation and oxidative stress, and thus resisting the development of atherosclerosis. These findings demonstrate the efficacious therapeutic impact of monotropein on atherosclerosis and elucidate its specific target.

Objective:To investigate the effects of regular yoga practice on pulmonary function and mechanical parameters of diaphragm.Methods:Eighty regular yoga practitioners, including 40 practicing for≤5 year (yoga≤5 years group) and 40 for>5 year (yoga>5 years group) were recruited in Shanxi Norman Bethune Hospital from January 2024 to April 2024; and 40 sedentary subjects were also recruited as the control group. The diaphragmatic motion was evaluated by two-dimensional ultrasound and speckle tracking ultrasound in all subjects, the parameters, including displacement, fractional thickening, strain and strain rate of diaphragm were observed at rest and deep breathing. At the same time, the pulmonary function tests were performed, the indexes including forced vital capacity (FVC), forced expiratory volume in 1 second (FEV 1) and one-second rate (FEV 1/FVC) were measured in all subjects. The mechanical parameters of diaphragm and the pulmonary function were compared among three groups. Results:There were no significant differences in gender ( χ2= 0.346), age ( F=1.16), height ( F=0.45), weight ( F=0.11) and body mass index (BMI) ( F=0.07) among the three groups (all P>0.05).At the rest status, there was no significant difference in diaphragm displacement, thickening rate and strain among three groups ( F=1.21, 2.10 and 0.23,all P>0.05); the strain rate of yoga>5 years group was lower than that of other two groups ( t=-4.23、-4.10, all P<0.05); however, there was no significant difference between yoga≤5 years group and control group ( t=-0.06, P>0.05). During deep breathing, the increment of displacement, thickening rate, strain and strain rate of diaphragm in yoga>5 years group was larger than that in other tow groups, while the increment of yoga≤5 years group was larger than that in control group ( F=25.82, 60.99, 17.29 and 52.46, all P<0.05); the increment of FVC, FEV 1 and FEV 1/FVC in yoga>5 years group was larger than other two groups, whilc the increment of yoga≤5 years group was larger than that of sedentary group (F=4.49, 7.32 and 39.71, all P<0.05). The diaphragmatic displacement was positively correlated with FVC ( r=0.290, P<0.05), and diaphragmatic displacement and thickening rate were positively correlated with FEV 1 and FEV 1/FVC (0.333 and 0.448, 0.231 and 0.599, all P<0.05), the strain and strain rate of diaphragm were negatively correlated with FEV 1 and FEV 1/FVC ( r=-0.399 and -0.719, -0.355 and -0.796, all P<0.05). Conclusion:The regular yoga practice can improve the movement capacity and efficiency of diaphragm, improve the pulmonary function, and there is a negative correlation between the strain rate and the mechanical parameters of diaphragm and FEV 1, FEV 1/FVC.

Objective:To understand the iodine nutrition status of 8 - 10 years old children in Yantai City, and to provide a scientific basis for scientific iodine supplementation according to local conditions.Methods:Using multi-stage stratified cluster random sampling method, each county (city and district, hereinafter referred to as county) in Yantai City in 2022 was divided into 5 areas according to east, west, south, north and center, and 1 township (street) was selected as the survey site for each area, and 1 school was selected for each survey site, and 40 non-residential children aged 8 - 10 years old in each elementary school were selected as the target respondents, and the salt samples of edible salt in their homes were collected, and the urine samples of salt iodine and urinary iodine content were measured at random. A sample of salt and a random sample of urine were collected from the children's homes, and the salt iodine and urine iodine content were measured. Some of the children were sampled and their thyroid gland was tested using ultrasound. Each survey site is based on administrative villages (communities); administrative villages with centralized water supply collect one sample of terminal water; administrative villages with decentralized water supply take two wells (or all of them if there are fewer than 10 wells) in each of the five directions: east, west, south, north, and central, and collect water samples from the wells to test the iodine content of the water. Zhifu District and Zhaoyuan City each took 2 canteens of enterprises and institutions and 5 medium-sized and 5 small restaurants to collect salt samples of edible salt and test the salt iodine content.Results:A total of 2 343 children were tested for urinary iodine and salt iodine; the median urinary iodine was 147.10 μg/L, and the median urinary iodine in children from different regions was 173.96, 148.20, 148.05, and 136.04 μg/L, respectively, with statistically significant differences ( H = 15.55, P = 0.001); the median salt iodine was 17.81 mg/kg, and the different regional The median salt iodine was 0.00, 0.00, 20.02, and 22.48 mg/kg, respectively, and the difference was statistically significant ( H = 263.48, P < 0.001); the iodized salt coverage rate (15.34%, 48.37%, 69.63%, and 76.69%) and the consumption rate of qualified iodized salt (13.50%, 39.14%, 61.86%, and 69.17%) were compared in different regions were compared, and the differences were statistically significant (χ 2 = 257.65, 235.64, P < 0.001). A total of 1 419 children underwent ultrasound examination of the thyroid gland, and there were no statistically significant differences when comparing the rates of goiter (2.44%, 2.18%, 3.04%, and 3.12%) and nodule detection (3.90%, 4.90%, 5.89%, and 2.18%) among the children in different regions (χ 2 = 0.85, 6.69, P > 0.05). A total of 2 488 water samples were monitored, and the median water iodine was 3.70 μg/L. When comparing the median water iodine in different regions, the difference was statistically significant ( H = 141.21, P < 0.001). A total of 120 salt samples of edible salt from catering units were tested, and the consumption rate of qualified iodized salt was 62.50%. Conclusion:The consumption rate of qualified iodized salt among children in Yantai was below 90%, but their iodine nutrition was at an appropriate level, suggesting that the iodine intake of children in Yantai may not be entirely dependent on iodized salt.

Aim To investigate the inhibition role and mechanism of adipose derived mesenchymal stem cell(ADMSC)exosomes(Exo)on adverse ventricular remodeling after myocardial infarction(MI).Methods The chan-ges of autophagy and inflammasomes phenotype of cardiac fibroblasts after H2O2 treatment were observed.MI rats were in-jected with an equal volume of normal saline,adipose derived mesenchymal stem cell exosomes(MSC-Exo)or fibroblast exosomes(MEF-Exo)via a tail vein.The expression of autophagy related 16 like protein 1(ATG16L1),autophagy re-lated protein 7(ATG7)and NOD-like receptor protein 3(NLRP3),inflammatory response,the degree of myocardial fi-brosis,and the cardiac function were observed in different groups.Results After treatment with H2O2 on cardiac fi-broblasts,the expressions of ATG16L1 and ATG7 were significantly decreased(P＜0.001),NLRP3 was significantly in-creased(P＜0.001),and the levels of inflammatory cytokines interleukin-1β(IL-1β)and IL-18 were significantly elevated(P＜0.001).After MI rats were intervened with MSC-Exo,the expressions of autophagy related proteins ATG16L1 and ATG7 were significantly up-regulated(P＜0.001),NLRP3 was significantly down-regulated(P＜0.001),serum IL-1β and IL-18 levels were significantly decreased(P＜0.001),fibrosis-related proteins collagen Ⅰ and Ⅲ were significantly reduced(P＜0.001),myocardial fibrosis was significantly relieved(P＜0.001),and cardiac function was sig-nificantly improved(P＜0.001).Conclusion Adipose derived MSC-Exo play a role in inhibiting adverse ventricular remodeling after MI by regulating the balance of autophagy and NLRP3 inflammasomes.
