ObjectiveBased on the zebrafish model， the hepatotoxicity and anti-osteoporotic activity of evodiamine （EVO） were studied. The mechanism of EVO in treating osteoporosis was explored by using network pharmacology and real-time polymerase chain reaction（Real-time PCR）. MethodsThree days after fertilization （3 dpf）， zebrafish were randomly selected and exposed to different concentrations of EVO solution for 96 hours. The mortality rate of zebrafish at different concentrations was calculated at the exposure endpoint， and a "dose-toxicity" curve was drawn. The 10% lethal concentration （LC₁₀） was calculated. Liver phenotype， acridine orange staining， and pathological tissue sections of liver-transgenic zebrafish ［CZ16 （gz15Tg.Tg （fabp 10a： ds Red； ela31： EGFP））］ were used to confirm hepatotoxicity of EVO. On this basis， prednisolone was used to create a model of osteoporosis in zebrafish. The skull development， area of the skull stained by alizarin red， and cumulative optical density were used as indicators to evaluate the anti-osteoporotic activity of EVO in a safe dose. Based on network pharmacology， the mechanism of action of EVO in the treatment of osteoporosis was predicted and verified through Real-time PCR. ResultsThe LC₁₀ of EVO on zebrafish （7 dpf） was determined to be 0.4 mg·L^-1. Compared with the control group， sublethal concentrations （10=0.36 mg·L^-1 and 1/2LC₁₀=0.18 mg·L^-1） significantly decreased the fluorescence area of zebrafish liver （P<0.05，P<0.01） and increased the number of liver cell apoptosis. The arrangement of liver tissue was disordered and loose， and the vacuole was obvious， especially in the 0.36 mg·L^-1 group. Compared with the control group， under safe dose conditions， 0.08 and 0.02 mg·L^-1 of EVO had no significant effect on the liver. Prednisolone administration significantly reduced the mineralization area and cumulative optical density of zebrafish skulls （P<0.01） compared with the control group. The mineralization area and cumulative optical density of zebrafish skulls in the 0.08 and 0.02 mg·L^-1 groups of EVO were significantly increased compared with the model group （P<0.01）. Network pharmacology prediction suggested that EVO may regulate key targets such as avian sarcoma viral oncogene homolog （SRC）， signal transducer and activator of transcription 3 （STAT3）， interleukin-8 （CXCL8） and tyrosine kinase receptor 2 （ERBB2） to regulate signaling pathways related to lipid and atherosclerosis in diabetic complications， as well as the regulation of inflammatory mediators of tryptophan （TRP） channels. Real-time PCR experiment results indicated that EVO could regulate the above-mentioned targets， as well as genes related to osteoblasts and osteoclasts. ConclusionExcessive doses of EVO can lead to hepatotoxicity in zebrafish. Under safe dosage conditions， EVO can regulate relevant targets to exert anti-osteoporotic activity， providing a reference for the clinical safe use of EVO and ideas for the development of new drugs for osteoporosis.

ObjectiveTo investigate the regulatory effect and potential mechanisms of isocitrate dehydrogenase 3A （IDH3A） on cardiomyocyte hypertrophy. MethodsThe expression of IDH3A in the myocardium of healthy volunteers （n=10） and patients with heart failure （HF） （n=10）， and in the myocardium of mice subjected to transverse aortic constriction （TAC） surgery and sham operation， as well as in phenylephrine （PE）-induced neonatal rat ventricular cardiomyocytes （NRVCs）， was assessed by real-time quantitative polymerase chain reaction （RT-qPCR） and Western blot assay. The effect of adenovirus-mediated overexpression of IDH3A on the expression of hypertrophy-related genes in PE-induced NRVCs was also evaluated. The effect of IDH3A on NRVCs area was examined by phalloidin staining assay. A mutant of IDH3A with abolished enzymatic activity， IDH3A_D208A， was generated through site-directed mutagenesis. The impact of this IDH3A mutant on the hypertrophic phenotype， ATP and ROS levels in NRVCs was evaluated to investigate whether the regulatory role of IDH3A in cardiomyocyte hypertrophy was dependent on its enzymatic activity. The effect of exogenous α-ketoglutaric acid （AKG） on cardiomyocyte hypertrophy was also detected by Western blot and phalloidin staining assay， respectively. ResultsIDH3A was significantly decreased in the myocardium of HF patients， in the myocardium of TAC-operated mice， and in PE-induced NRVCs （P = 0.005 2，P = 0.026 6，P = 0.041 3 and P = 0.006 6， respectively）. Overexpression of IDH3A markedly suppressed the expression of hypertrophy-related genes and the increase of cell size of PE-induced NRVCs （P < 0.000 1， P = 0.000 1 and P = 0.000 2， respectively）. The ATP and ROS analysis indicated that IDH3A inhibited the increases of ATP and ROS levels in PE-induced NRVCs （P = 0.001 2 and P<0.000 1， respectively）， whereas the enzymatically inactive IDH3A mutant lacked this effect. Exogenous AKG provision could， but overexpression of IDH3A mutant failed to suppress PE-induced NRVCs hypertrophy. ConclusionIDH3A inhibits cardiomyocyte hypertrophy via elevating AKG level， providing scientific evidence for study on IDH3A-based treatment of cardiac hypertrophy.

ObjectiveTo investigate the possible mechanism of Guben Fangxiao Beverage （固本防哮饮） for the prevention and treatment of chronic airway inflammation during asthma remission. MethodsThirty-six female Balb/c mice were randomly divided into normal group， model group， low-， medium-， and high-dose of Guben Fangxiao Beverage group and montelukast sodium group， with 6 mice in each group. Except for the normal group， ovalbumin and respiratory syncytial virus were used in other groups to establish a mouse model of bronchial asthma in remission stage. After molding， the low-， medium-， and high-dose groups of Guben Fangxiao Beverage were respectively given 12， 24， and 36 g/（kg·d）， the montelukast sodium group was given montelukast sodium granule 2.6 mg/（kg·d）， and the mice in the normal group and model group were given 20 ml of double-distilled water， all by gavage， once a day for 28 days. The levels of interleukin 4 （IL-4） and interleukin 5 （IL-5） in the lung tissue of mice were detected； HE staining was used to observe the pathology of the lung tissue and to score the inflammation； DHE staining was used to observe the level of reactive oxygen species （ROS） in the lung tissue， and the activities of mitochondrial respiratory chain complexes Ⅰ， Ⅱ， Ⅲ， Ⅳ， and Ⅴ in the lung tissue were detected； the levels of serum superoxide dismutase （SOD）， catalase （CAT）， malondialdehyde （MDA） and adenosine triphosphate （ATP） were detected； the protein expression levels of phosphorylated adenosine monophosphate-activated protein kinase （p-AMPK）， nuclear factor erythroid 2-related factor 2 （Nrf2）， haem oxygenase 1 （HO-1） and cAMP responsive element binding protein （CREB） in the lung tissues of the model group were detected by Western blot. ResultsCompared with the normal group， the histopathological results of the lungs of mice in the model group showed an increase in inflammatory cells around the airways and an increase in inflammatory score； DHE staining showed an increase in the level of ROS， and an increase in the levels of IL-4 and IL-5 in the lung tissues； the levels of serum SOD， CAT， and ATP were reduced， and the level of MDA was elevated； the activities of the mitochondrial respiratory chain complexes Ⅰ， Ⅱ， Ⅲ， Ⅳ， and Ⅴ of the lung tissues were reduced， and the activities of p-AMPK， Nrf2， CREB protein expression decreased （P＜0.05）. Compared with the model group， the lung tissue inflammatory cells and inflammation scores of mice in each Guben Fangxiao Beverage dose group and montelukast sodium group were reduced； the levels of ROS， IL-4 and IL-5 in the lung tissue were reduced； the levels of CAT and ATP in the serum increased， and the content of MDA was reduced； and the activities of mitochondrial respiratory chain complexes Ⅰ and Ⅱ， as well as the expression of CREB protein， were elevated in the lung tissue （P＜0.05）. Compared with the high-dose group， the MDA level of the medium-dose Guben Fangxiao Beverage group decreased （P＜0.05）. The activity of mitochondrial respiratory chain complex V in the medium-dose group was higher than that in the montelukast sodium group， and the activity of mitochondrial respiratory chain complex Ⅳ in the medium- and high-dose groups was higher than that in the low-dose group （P＜0.05）. ConclusionGuben Fangxiao Beverage can inhibit oxidative stress and improve mitochondrial function to relieve chronic airway inflammation in bronchial asthma model mice during asthma remission， and its mechanism may be related to the activation of AMPK/Nrf2/HO-1 signaling pathway.

As people's living standards improve， the development trend of diabetes has gradually become severe. Diabetes is a chronic inflammatory disease associated with abnormal expression of nuclear factor-kappa B （NF-κB） in patients. NF-κB exists in various tissue cells and participates in the regulation of a variety of genes related to immune function and inflammation. Varieties of factors can activate NF-κB when the body is stimulated by external factors， so as to produce inflammation and other reactions. Previous studies on NF-κB mainly focus on cancer， and the pathological mechanism of the treatment of diabetes by related signaling pathways and the progress of traditional Chinese medicine （TCM） treatment have not been systematically elaborated on. By referring to the relevant literature in China and abroad， it was found that NF-κB is not isolated in the development and progression of diabetes but is associated with signal molecules related to inflammation， oxidative stress， and energy metabolism， and it is involved in mediating inflammation， pancreatic β cell apoptosis， insulin signal transduction， and other physiological functions. Therefore， blocking the transmission of NF-κB signaling pathway is beneficial to the treatment of diabetes. At present， Western medicine for the treatment of diabetes mainly includes oral hypoglycemic drugs and insulin injections， but the adverse reactions are obvious. TCM has been characterized by multi-target， extensive action， and excellent curative effects in the treatment of diabetes. TCM and its compounds with functions of tonifying Qi and promoting blood circulation， regulating qi and eliminating phlegm， clearing heat and detoxifying， and nourishing Yin and moistening dryness can effectively intervene in the abnormal expression of NF-κB signaling pathway in vivo through anti-inflammatory effects. In this paper， the association between NF-κB signaling pathway and diabetes was summarized， and the modern research progress of TCM intervention of NF-κB signaling pathway in the treatment of diabetes in the past five years was reviewed， so as to lay a laboratory foundation for the study of a new pathological mechanism of diabetes based on NF-κB signaling pathway and provide new targets and research direction for the prevention and treatment of diabetes and development of related TCM.

ObjectiveBased on the new method of animal model evaluation， this paper summarized and analyzed the characteristics of traditional Chinese medicine（TCM） and Western medicine syndromes in existing autism spectrum disorder（ASD） animal models， and put forward suggestions for improvement. MethodRelevant literature on ASD animal models in China National Knowledge Infrastructure（CNKI） and PubMed were searched. According to the diagnostic standards of traditional Chinese and western medicine， core symptoms and accompanying symptoms were assigned values， and the clinical consistency of the models was comprehensively evaluated. ResultMost ASD model experimental animals were rodents， and the modeling methods included genetic and non-genetic. Domestic research focused on biochemical induction， while foreign research used genetic models more commonly. Among all models， valproic acid induction had the highest clinical consistency， followed by the neuroligin 4（NLGN4） and contactin associated protein like 2（CNTNAP2） gene knockout models. Most modeling methods could meet the characteristics of surface validity and structural validity， but did not clearly distinguish TCM syndromes. Currently， there is no model that has a high degree of clinical agreement between TCM and western medicine at the same time. ConclusionThe existing ASD animal models are mostly constructed under the guidance of western medicine， which lacks the characteristics of TCM syndromes. And the selection of evaluation indicators of western medicine is relatively single， without specifying the types of TCM syndromes. It is recommended to apply TCM intervention factors during the process of model preparation， to improve the evaluation indicators of traditional Chinese and western medicine， and to emphasize the study of on non-human primates， so as to lay a solid foundation for future experiments.

The levels of TNF-α and IL-6 in the serum of mice in the MLE-H and metformin groups were significantly decreased （P<0.01）. The renal tissue pathology of mice in each drug administration group was improved to varying degrees， and the protein expression levels of TLR4， MyD88， and NF-κB p65 in the MLE-H group were decreased significantly （P<0.05， P<0.01）. ConclusionMLE can improve the renal structure and function of db/db diabetic mice， and its mechanism may be related to the inhibition of the TLR4/MyD88/NF-κB signaling pathway.

Mori Folium， the dried leaves of Morus alba， is widely used in clinical practice for dispersing wind and heat， clearing the lung and moistening dryness， soothing the liver and improving vision， and cooling blood and stopping bleeding. It has been used to regulate blood glucose since ancient times， and modern studies have shown that the active components of Mori Folium for lowering blood glucose mainly include flavonoids， alkaloids， polysaccharides， and phenols. These components are mainly extracted by solvents such as water and alcohols with the assistance of ultrasound and microwave. In addition， new extraction methods are emerging， such as CO₂ supercritical fluid extraction， enzymatic hydrolysis， and cloud point extraction. Mori Folium lowers blood glucose via multiple components， pathways， and targets. Specifically， it can improve glucose and lipid metabolism， protect pancreatic β cells， and alleviate insulin resistance to reduce the damage caused by hyperglycemia and restore normal physiological functions. Although a large number of studies have been carried out on diabetes， the causes and radical treatment methods remain to be explored， and diabetes is still a major disease that endangers human health and needs to be solved urgently. The articles about extraction process and mechanism of active components in Mori Folium for lowering blood glucose were retrieved from the China National Knowledge Infrastructure （CNKI）， Web of Science， and PubMed. We analyzed the applicable extraction methods for the blood glucose-lowering components such as flavonoids， polysaccharides， and alkaloids in Mori Folium， and compared the conventional and emerging methods. Furthermore， we summarized our research achievements in the extraction of active components from Mori Folium and the blood glucose-lowering effect and mechanisms. This review aims to provide theoretical support for the optimization of the extraction process， the research on the blood glucose-lowering components and mechanism， and the development of new drugs and clinical application of Mori Folium.
