OBJECTIVE To investigate the improvement effects of glycyrrhizin （GL） on Helicobacter pylori （HP）-associated gastritis in rats and its mechanism. METHODS HP-associated gastritis rat model was induced by inoculating with 1×109 cfu/mL HP. The model rats were randomly divided into model group， positive control group （HP standard quadruple group）， GL low-dose， medium-dose and high-dose groups （5， 20， 50 mg/kg）， with 12 rats in each group. Another 12 healthy rats were selected as normal control group. Except the normal control group and model group were given constant volume of normal saline intragastrically， the other groups were given corresponding drugs intragastrically， once a day， for 30 consecutive days. After administration， rats received 13C urea breath test， and delta-over-baseline （DOB） was recorded； the pathological and cellular morphological changes of gastric mucosa in rats were observed， and pathological scoring was performed； the levels of interleukin-8 （IL-8）， IL-1β， tumor necrosis factor-α （TNF-α）， reactive oxygen species （ROS） and malondialdehyde （MDA） were detected in gastric mucosa of rats； mRNA expressions of high mobility group box-1 protein （HMGB1） and nuclear factor-κ-B （NF-κB）， relative expressions of nitric oxide synthases （iNOS） and HMGB1， the phosphorylation level of NF- κBp65 were also detected in rats. RESULTS Compared with normal control group， the DOB value， histopathological score of gastric mucosa， the levels of IL-8， IL-1β， TNF-α， ROS and MDA， relative expressions of HMGB1 and NF- κB mRNA， relative expressions of iNOS and HMGB1 protein and the phosphorylation level of NF-κB p65 were all increased significantly in model group （P＜0.05）； the epithelial cells of gastric mucosa in rats were incomplete in structure and decreased in the number， with an increase in cell fragments and vacuoles， and significant cell pyknosis. Compared with model group， the changes of the above indexes in GL groups and positive control group were significantly reversed （P＜0.05）； the changes in the above indicators in the GL high-dose group were more significant than GL low-dose and medium-dose groups （P＜0.05）； the pathological changes of gastric mucosal cells in rats had all improved. CONCLUSIONS GL may inhibit inflammation and oxidative stress by inhibiting the activation of HMGB1/NF-κB pathway， thus relieving HP-induced gastric mucosal injury.

OBJECTIVE To explore the mechanism of limonin treating in hepatic fibrosis through network pharmacology, and validate its mechanism by molecular docking and animal experiments. METHODS Firstly, the targets of limonin and hepatic fibrosis were screened from the SwissTargetPrediction, GeneCards and DisGeNet database, etc. Meanwhile, the common targets of limonin and hepatic fibrosis were obtained from the bioinformatics website. The protein protein interaction network of common target was constructed by using STRING database and Cytoscape software, and the CytoNCA plug-in was used to screen core targets. And then the enrichment analysis of GO and KEGG on the common target was performed by Metascape database. Thereby, the possible mechanism of limonin against hepatic fibrosis were predicted. Finally, the AutoDock Vina was used for molecular docking verification, and the prediction results of network pharmacology were verified by animal experiments. RESULTS The prediction results indicated that limonin might acted on 86 targets including AKT1, VEGFA and HIF1A, and participated in biological processes including hormone response, protein phosphorylation, angiogenesis, and PI3K-Akt pathway, HIF-1 pathway, VEGF pathway and other signaling pathways related to hepatic fibrosis. The results of protein protein interaction network topology analysis showed that the 11 core targets including AKT1, VEGFA, HIF1A and PIK3CA, etc. Molecular docking results showed that limonin had strong affinity and relatively stable binding conformation with the core targets. In the animal experiments, compared with the model group, hyaluronidase(HA) and laminin(LN) in rat serume in high-dose group of limonin(LH) and low-dose group of limonin(LL)(except for LN in LL group) were declined(P<0.01 or P<0.05), and the degree of inflammation and hepatic fibrosis were relieved to different degrees in liver tissue of the LH group and LL group; Western blotting and qPCR detection showed that protein and mRNA expression levels of AKT, HIF-1α and VEGF(except for VEGF in LL group) was down-regulated in the LH group and LL group(P<0.01 or P<0.05). CONCLUSION Limonin may acts on AKT1, VEGFA, HIF1A and other core targets to treat hepatic fibrosis angiogenesis, which may be related to the inhibition of AKT/HIF-1α/VEGF signaling pathway.

Objective To explore the categories of dyadic mental health literacy among stroke patients and their caregivers,and to analyze the differences in the characteristics of different classes of stroke patients and their caregivers.Methods A convenient sampling method was used to select 287 dyads of stroke patients and their caregivers who were treated at a tertiary general hospital in Henan province from July to October 2020.The general information questionnaire,Multicomponent Mental Health Literacy and Social Support Rating Scale were used for investigation.Latent profile analysis was adopted to explore the categories of dyadic mental health literacy,and multiple logistic regression was used to analyze the influencing factors of each category.Results Stroke patients and their caregivers were divided into 4 categories based on scores of mental health literacy:dyadic low resource group(19.86％),dyadic low literacy group(54.36％),dyadic low belief group(11.15％),dyadic high literacy group(14.63％).The patient's age,average monthly household income,the caregiver's age,the caregiver's Social Support Rating Scale score,the caregiver's educational level,daily care time and total time length of care were the factors influencing the categories of dyadic mental health literacy among stroke patients and their caregivers(P＜0.05).Conclusion Stroke patients and their caregivers were divided into 4 categories based on scores of mental health literacy.Medical staff should carry out comprehensive psychological interventions for stroke patients and their caregivers with different dyadic mental health literacy characteristics,so as to improve dyadic mental health literacy.

【Objective】 To explore the effects of perceived risk of COVID-19 of college students on their anxiety and depression, as well as the roles of attention to negative information and perceived social support, so as to provide theoretical basis for colleges and universities to formulate corresponding intervention measures. 【Methods】 By the convenience sampling method, totally 1 404 college students from Shaanxi and Henan provinces were investigated online by using General Information Questionnaire, Perceived Risk of COVID-19 Pandemic Scale, Attention to Negative Information Scale, Patient Health Questionnaire, Generalized Anxiety Disorder and Perceived Social Support Scale. SPSS 20.0 was used for data analysis, Pearson correlation method was used to explore the correlation between variables. The mediating effect of attention to negative information and the moderating effect of perceived social support were analyzed by PROCESS. 【Results】 The scores of anxiety and depression of the 1 404 college students included in the study were 4.03±4.48 and 6.21±5.41, respectively. The detection rate of anxiety symptom was 29.9%, and that of depression symptom was 44.4%. The risk perception of COVID-19 epidemic of the college students was positively correlated with attention to negative information (r=0.373, P<0.001), anxiety (r=0.227, P<0.001), and depression (r=0.226, P<0.001). Anxiety (r=0.553, P<0.001) and depression (r=0.497, P<0.001) were positively correlated with attention to negative information, while perceived social support was negatively correlated with the risk perception of the COVID-19 (r=-0.154, P<0.001), attention to negative information (r=-0.259, P<0.001), anxiety (r=-0.321, P<0.001) and depression (r=-0.278, P<0.001). The risk perception of COVID-19 affected the anxiety and depression of the students mainly through the mediating effect of attention to negative information. The total effect of risk perception of COVID-19 and anxiety was 0.227, and the mediating effect accounted for 80.18% of the total effect. The total effect of risk perception of COVID-19 and depression was 0.228, and the mediating effect accounted for 90.35% of the total effect. Perceived social support played a moderating role in the last half of this mediating model. 【Conclusion】 Risk perception of COVID-19 indirectly affects the occurrence of anxiety and depression in college students through attention to negative information, and perceived social support plays a moderating role in this mediating model. The findings suggest that when a risk event occurs, colleges and universities should pay attention to guiding students to adjust their attentional bias to external information, and give students enough care and support to improve their mental health.

ObjectiveTo investigate the effects of Asari Radix et Rhizoma-Zingiberis Rhizoma herb pair （XGHP） on lung and liver lipid metabolism in rats with chronic obstructive pulmonary disease （COPD）. MethodForty SD male rats were divided into a normal group （10 rats） and a model group （30 rats）. The method of cigarette smoke + tracheal injection of lipopolysaccharide（LPS） + cold stimulation was used to replicate COPD model with the syndrome of cold phlegm obstruction in lung. A COPD group， a XGHP group （5.4 g·kg^-1·d^-1）， and an aminophylline group （0.5 g·kg^-1·d^-1） were established after successfully inducing the model， with 10 rats in each group. After treatment， the serum triglyceride （TG）， total cholesterol （TC）， high-density lipoprotein cholesterol （HDL-C）， and low-density lipoprotein cholesterol （LDL-C） levels of rats in each group were measured. Gas chromatography-mass spectrometer （GC-MS） was used to detect the differential metabolites in the lung and liver tissues of rats in each group， and the relevant targets of the differential metabolites were predicted by network pharmacology. Molecular docking was used to verify the binding ability of key components in XGHP to the relevant targets in network pharmacology. The mRNA and protein expression levels of peroxisome proliferator-activated receptor α （PPARα） and fatty acid binding protein 4 （FABP4） in lung and liver tissues of rats in each group were detected by real-time polymerase chain reaction （PCR） and Western blot. ResultXGHP significantly increased the levels of TG， TC， and LDL-C in serum （P<0.05）， and decreased the level of HDL-C （P<0.05） in rats with COPD. GC-MS results showed that there were 8 lung differential metabolites and 17 liver differential metabolites in the COPD group and XGHP group. Network pharmacology predicted 59 common targets for the two differential metabolites， mainly enriched in the PPAR signaling pathway. Molecular docking results showed that the main components in XGHP were well combined with both PPARα and FABP4. Real-time PCR showed that XGHP effectively up-regulated the expression levels of PPARα and FABP4 mRNA （P<0.05）， and Western blot showed that XGHP effectively up-regulated the expression levels of PPARα and FABP4 proteins （P<0.05） in lung and liver tissues of rats with COPD. ConclusionXGHP effectively improves the blood lipid levels of rats with COPD， which may be related to the increase of the expression levels of PPARα and FABP4 mRNA and proteins in the PPAR signaling pathway， thus regulating lung and liver lipid metabolism.

OBJECTIVE：To study the mechanism of improvement effects of Fupi rougan granule （FRG）on hepatic fibrosis model rats. METHODS ：The rats were randomly divided into blank group ，model group ，Colchicine tablet group （chemical positive control ，0.2 mg/kg），Fuzheng huayu capsule group （TCM positive control ，0.415 g/kg），FRG low-dose ，medium-dose and high-dose groups （20，40，80 g/kg），with 10 rats in each group ，except for 11 rats in blank group and model group （one rat was used to judge whether the modeling was successful ）. Except for blank group ，other groups were given intraperitoneal injection of 50％ CCl4 olive oil solution and intragastric administration of 30％ ethanol to induce hepatic fibrosis model. After modeling ， administration groups were given relevant medicine intragastrically ；blank group and model group were given constant volume of normal saline intragastrically ，once a day ，for consecutive 4 weeks. After last administration ，morphology changes of liver tissue in rats were observed. The serum levels of HA ，LN，PCⅢ and Col Ⅳ in rats were detected ，and protein expression of Beclin- 1 and LC3-Ⅱin liver tissue were also determined. mRNA and protein expression of Akt ，AMPK，mTOR，p70S6K were detected in liver tissues of rats. RESULTS ：Compared with blank group ，the structure of hepatic lobules in the model group was disordered ，the proliferation of fibrous tissue was obvious ，and some pseudolobules were formed ；the serum levels of HA ，LN，PCⅢ and Col Ⅳ， the protein expression of Beclin- 1 and LC 3-Ⅱ in liver tissue as well as mRNA and protein expression of Akt ，AMPK，mTOR and p70S6K were increased significantly （P＜0.01）. Compared with model group ，the liver injury of rats in FRG groups was significantly relieved ，and the levels of the above indexes in serum and liver tissue （except for LN and PC Ⅲ in FRG low-dose group） were significantly reduced （P＜0.05 or P＜0.01）. CONCLUSIONS ：FRG can improve hepatic fibrosis in rats ，the mechanism of which may be associated with down-regulating the expression of autophagy associated protein and Akt/AMPK/mTOR/ p70S6K signaling pathway related protein.
