ObjectiveTo investigate the effect of Danggui Shaoyaosan on ferroptosis in the rat model of non-alcoholic fatty liver disease (NAFLD) and explore the underlying mechanism based on the nuclear factor E2-related factor 2 (Nrf2)/solute carrier family 7 member 11 (SLC7A11)/glutathione peroxidase 4 (GPX4) signaling pathway. MethodsThe sixty SD rats were randomly grouped as follows: control, model, Yishanfu (0.144 g·kg-1), and low-, medium-, and high-dose (2.44, 4.88, and 9.76 g·kg-1, respectively) Danggui Shaoyaosan. A high-fat diet was used to establish the rat model of NAFLD. After 12 weeks of modeling, rats were treated with corresponding agents for 4 weeks. Then, the body weight and liver weight were measured, and the liver index was calculated. At the same time, serum and liver samples were collected. The levels or activities of total cholesterol (TC), triglycerides (TG), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and Fe2+ in the serum and TC, TG, free fatty acids (FFA), malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPX), and Fe2+ in the liver were measured. Hematoxylin-eosin staining and oil red O staining were employed to observe the pathological changes in the liver. Immunofluorescence was used to assess the reactive oxygen species (ROS) content in the liver. Mitochondrial morphology was observed by transmission electron microscopy. The protein levels of Nrf2, SLC7A11, GPX4, transferrin receptor 1 (TFR1), and divalent metal transporter 1 (DMT1) in the liver were determined by Western blot. ResultsCompared with the control group, the model group showed increases in the body weight, liver weight, liver index, levels or activities of TC, TG, ALT, AST, and Fe2+ in the serum, levels of TC, TG, FFA, MDA, Fe2+, and ROS in the liver, and protein levels of TFR1 and DMT1 in the liver (P<0.01), and decreases in the activities of SOD, GPX and the protein levels of Nrf2, SLC7A11, and GPX4 in the liver (P<0.05, P<0.01). Meanwhile, the liver tissue in the model group presented steatosis, iron deposition, mitochondrial shrinkage, and blurred or swollen mitochondrial cristae. Compared with the model group, all doses of Danggui Shaoyaosan reduced the body weight, liver weight, liver index, levels or activities of TC, TG, ALT, AST, and Fe2+ in the serum, levels of TC, TG, FFA, MDA, Fe2+, and ROS in the liver, and protein levels of TFR1 and DMT1 in the liver (P<0.01), while increasing the activities of SOD and GPX and the protein levels of Nrf2, SLC7A11, and GPX4 in the liver (P<0.01). Furthermore, Danggui Shaoyaosan alleviated steatosis, iron deposition, and mitochondrial damage in the liver. ConclusionDanggui Shaoyaosan may inhibit lipid peroxidation and ferroptosis by activating the Nrf2/SLC7A11/GPX4 signaling pathway to treat NAFLD.

Objective To investigate the correlation between the concentration of air pollutants (PM10, SO2, NO2) and the number of outpatient and emergency visits for pediatric respiratory diseases in a general hospital in Shanghai. Methods Data including pediatric respiratory disease outpatient and emergency visits in a hospital in Pudong New Area of Shanghai from May 1, 2013 to March 20, 2022 were collected. Daily concentration of air pollutants including PM10, SO2 and NO2 and meteorological data in Pudong New Area during the same period were collected. A case-crossover study with distributed lag non-linear model was conducted to explore the correlation between air pollutants (PM10, SO2, NO2) and the number of outpatient and emergency visits for pediatric respiratory diseases. Results The concentrations of PM10, SO2 and NO2 were positively with the number of outpatient and emergency visits for pediatric respiratory diseases. The strongest cumulative effect was observed on six days lag (Lag0-5) for PM10. For a 10 μg/m3 increase of the concentrations of PM10, the corresponding increase of cumulative pediatric respiratory disease outpatients was 1.10% (95%CI:0.97%, 1.23%) in Lag0-5. The strongest cumulative effect was observed on eight days lag (Lag0-7) for SO2 and NO2. For a 10 μg /m3 increase of the concentrations of SO2 and NO2, the corresponding increase of cumulative pediatric respiratory disease outpatients was 5.64% (95%CI:5.16%, 6.13%) and 5.41% (95%CI:5.15%, 5.66%) in Lag 0-7, respectively. The association of PM10 and SO2 with the number of pediatric respiratory disease visits in males was significantly stronger than that in females. The impact of PM10 on the number of pediatric respiratory disease visits in children aged 0-6 was higher than that in children aged 7-14, while the impact of SO2 and NO2 on the number of pediatric respiratory disease visits in children aged 7-14 was higher than that in children aged 0-6. Conclusion The concentration of ambient PM10, SO2, and NO2 is positively correlated with outpatient and emergency visits for pediatric respiratory diseases, with obvious lag and cumulative effect. Boys and children aged 0-6 are more susceptible to the hazard of air pollution.

Objective To analyze the adolescent tuberculosis reported in Haikou region between 2018 and 2021 and factors influencing the outcome. Methods The data on adolescent tuberculosis cases reported in Tuberculosis Information Management System in the Haikou Regional Centre for Disease Control and Prevention (RCDC) from 2018 to 2021 were collected. A follow-up survey was carried out until 31 December 2022. The changes in reported incidence of adolescent tuberculosis in Haikou was analyzed, and multivariate Cox proportional hazards regression models were used to identify independent factors influencing the outcome of adolescent tuberculosis. Results A total of 265 cases of tuberculosis in adolescents were reported between 2018 and 2021, of which 55 were reported in 2018, 74 in 2019, 67 in 2020, and 69 in 2021. The total number of reported cases of tuberculosis was 140 among male adolescents, which was slightly higher than 125 among female adolescents. The number of reported cases of tuberculosis was 134 in adolescents ≥15 years of age and 131 in adolescents <15 years of age. No statistically significant difference was reported between good outcome group and poor outcome group in age, gender, place of residence, nationality, and domicile place (P>0.05), whereas difference was found in the history of tuberculosis between two groups (P<0.05). Multivariate Cox proportional hazards regression model denoted that retreated tuberculosis (HR: 2.172, 95%CI: 1.483-3.007), complicating underlying disease (HR: 1.451, 95%CI: 1.080-1.985), and number of sputum smears (HR: 2.617, 95%CI: 1.531-3.458) were the risk factors for adverse outcomes in adolescent tuberculosis. Conclusion From 2018 to 2021, the number of reported adolescents of pulmonary tuberculosis in Haikou increased, suggesting that the management and prevention of adolescents should be strengthened to improve the prognosis rate of adolescents.

Individuals with type 1 diabetes or advanced type 2 diabetes suffer insufficient insulin secretion, leading to symptoms of hyperglycemia. To maintain the normal blood glucose levels, those people with diabetes must administer insulin multiple times a day. However, insulin requirements are influenced by several factors such as diet, exercise, and illness, combined with the narrow therapeutic index, making accurate insulin dosage challenging. Excessive insulin administration can even pose life-threatening risks. In addition, frequent daily insulin injections place considerable physiological and psychological burdens on patients. To tackle these challenges, researchers have embarked on the development of closed-loop insulin delivery systems. These systems adjust insulin dosages in real-time changes based on the patient’s blood glucose levels, therefore enhancing both the safety and effectiveness of insulin therapy. This review categorizes closed-loop insulin delivery systems into two types: electronic-based and material-based systems, based on their compositional attributes. The exploration of both types covers their components, developmental history, clinical applications, current pros and cons, and future directions. The relative strengths and limitations of these two categories of closed-loop insulin delivery systems are also compared and discussed.
