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 understand the hospital discharge readiness and discharge instruction quality in chronic disease patients and to analyze the correlation between them. Methods Totals of 602 chronic disease patients of related departments from 7 ClassⅢGrade A hospitals in Shanghai were selected by convenience sampling. All of them were investigated with the general information questionnaire, Readiness for Hospital Discharge Scale (RHDS) and Quality of Discharge Teaching Scale (QDTS), and their data were analyzed. Results Among those patients, the scores of hospital discharge readiness and discharge instruction quality were (8.01±1.41) and (8.65±1.29) out of 10 respectively. The score of hospital discharge readiness had a positive correlation with the score of discharge instruction quality with a statistical difference (r=0.507, P< 0.01). Conclusions Hospital discharge readiness and discharge instruction quality of chronic disease patients are all in high levels and with a positive correlation. Nurses should enrich the content of discharge instruction to improve the quality of discharge instruction by appropriate instruction skills and to improve the hospital discharge readiness.

Autophagy is a self-decomposing process that is used to degrade long-lived proteins or necrotic organelles.It is extremely dependent on lysosomes,widely present in eukaryotic cells and highly conserved.Autophagy can protect the cells themselves and help them resist the adverse environment at a proper level,but excessive autophagy can result in autophagic cell death.In recent years,with the comprehensive research of autophagy,it has been found that autophagy is closely related to the development and progression of most tumors.More drugs associated with autophagy are used for the clinical treatment of tumors,but they have different therapeutic effects on different tumors,so the impact of autophagy-related drugs on normal cells need to be identified through more clinical trials and experimental studies.This paper reviews the roles of autophagy in the occurrence and development of tumors,and recent progress in the treatment of cancer by regulating autophagy through drugs.

Dietary pattern has been revealed to be associated with metabolic syndrome. However, the association was not well documented in Chinese due to the complexity of Chinese foods. We mainly assessed the dietary patterns and examined their effects on metabolic syndrome among Chinese adults. Four dietary patterns including 'Refined Grains & Vegetables' Pattern, 'Dairy & Eggs' Pattern, 'Organ Meat & Poultry' Pattern, and 'Coarse Grains & Beans' Pattern were extracted. 'Dairy & Eggs' Pattern was associated with a decreased odds of metabolic syndrome in women, and 'Coarse Grains & Beans' Pattern was associated with a decreased odds of hypertension in men. These results provided a scientific basis for future research and dietary guideline perfection.
