OBJECTIVE To investigate the effects and mechanism of asperuloside （Asp） on the pyroptosis of intestinal epithelial cells in rats with ulcerative colitis （UC）. METHODS The male SD rats were randomly divided into Control group， model group （UC group）， ASP low-dose and high-dose groups [Asp-L， Asp-H groups， Asp 35， 70 mg/（kg·d）]， ASP high-dose group+AMPK inhibitor Compound C group [Asp-H+Compound C group， Asp 70 mg/（kg·d）+Compound C 0.2 mg/（kg·d）]， with 12 rats in each group. Except for Control group， the other groups were injected with 50% ethanol （0.25 mL）+5% 2，4， 6- trinitrobenzene sulfonic acid solution （2 mL/kg） into the intestinal cavity to construct UC model. After modeling， the rats in each drug group were given corresponding drug solution by gavage or （and） tail vein injection， once a day， for 14 consecutive days. After the last administration， the weight of rats in each group was measured， and the length of their colons was measured； disease activity index （DAI） score and colonic mucosal damage index （CMDI） score were performed， and the serum levels of inflammatory factors （interleukin-18， -1β， -6） were detected. The pathological changes of the colon tissue were observed. The expressions of pyroptosis-related proteins [caspase-1， gasdermin D （GSDMD）] in colon tissue， and pathway-related proteins such as adenosine monophosphate-activated protein kinase （AMPK）， thioredoxin-interacting protein （TXNIP）， NOD-like receptor protein 3 （NLRP3） and apoptosis-associated speck-like protein containing a CARD （ASC） were all detected. RESULTS Compared with Control group， the colon tissue structure of rats in UC group was damaged， with obvious infiltration of inflammatory cells and edema. Their body weight， colon length and phosphorylation level of AMPK protein were significantly reduced or shortened； DAI and CMDI scores， serum levels of inflammatory factors， and the protein expressions of caspase-1， GSDMD， TXNIP， NLRP3 and ASC in colon tissue were increased or upregulated significantly （P＜0.05）. Compared with UC group， the pathological damage of colon tissue in rats was relieved in Asp-L and Asp-H groups， and all quantitative indicators were significantly improved （P＜0.05）； the improvement effect of Asp-H group was more significant （P＜0.05）. Compound C could significantly reverse the improvement effect of high-dose of Asp on the above indicators in UC rats （P＜0.05）. CONCLUSIONS Asp can improve inflammatory damage in colon tissue and inhibit pyroptosis of intestinal epithelial cells in UC rats， which is associated with the activation of AMPK and inhibition of TXNIP/NLRP3 signaling pathway.

OBJECTIVES: Shelter hospital was an alternative way to provide large-scale medical isolation and treatment for people with mild coronavirus disease 2019 (COVID-19). Due to various reasons, patients admitted to the large shelter hospital was reported high level of psychological distress, so did the healthcare workers. This study aims to introduce a comprehensive and multifaceted psychosocial crisis intervention model. METHODS: The psychosocial crisis intervention model was provided to 200 patients and 240 healthcare workers in Wuhan Wuchang shelter hospital. Patient volunteers and organized peer support, client-centered culturally sensitive supportive care, timely delivery of scientific information about COVID-19 and its complications, mental health knowledge acquisition of non-psychiatric healthcare workers, group activities, counseling and education, virtualization of psychological intervention, consultation and liaison were exhibited respectively in the model. Pre-service survey was done in 38 patients and 49 healthcare workers using the Generalized Anxiety Disorder 7-item (GAD-7) scale, the Patient Health Questionnaire 2-item (PHQ-2) scale, and the Primary Care PTSD screen for the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (PC-PTSD-5). Forty-eight healthcare workers gave feedback after the intervention. RESULTS: The psychosocial crisis intervention model was successfully implemented by 10 mental health professionals and was well-accepted by both patients and healthcare workers in the shelter hospital. In pre-service survey, 15.8% of 38 patients were with anxiety, 55.3% were with stress, and 15.8% were with depression; 16.3% of 49 healthcare workers were with anxiety, 26.5% were with stress, and 22.4% were with depression. In post-service survey, 62.5% of 48 healthcare workers thought it was very practical, 37.5% thought more practical; 37.5% of them thought it was very helpful to relief anxiety and insomnia, and 27.1% thought much helpful; 37.5% of them thought it was very helpful to recognize patients with anxiety and insomnia, and 29.2% thought much helpful; 35.4% of them thought it was very helpful to deal with patients' anxiety and insomnia, and 37.5% thought much helpful. CONCLUSIONS Psychological crisis intervention is feasible, acceptable, and associated with positive outcomes. Future tastings of this model in larger population and different settings are warranted.

Objective:To explore the current situation of nursing human caring in hospital wards and analyze its influencing factors, so as to facilitate the development of nursing human caring practice.Methods:From July to November 2022, a total of 107 hospitals were surveyed through stratified convenience sampling method, and 4 072 ward nursing managers were recruited to finish the general information questionnaire and the ward nursing human caring status questionnaire. The general information included the region, class and type of the hospital, etc. The ward nursing human caring status questionnaire included 38 items in 5 dimensions of nursing human caring system and process, humanistic quality and training of nursing staff, humanistic environment and facilities, human caring procedures and measures, and human caring quality evaluation and improvement, with a full score of 190 points. Descriptive statistics were used to analyze the general data, independent samples t-test, ANOVA and correlation analysis were used to analyze the factors influencing the current status of nursing human caring in the ward, while multiple linear regression analysis was used to conduct a multivariate analysis. Results:The score of nursing human caring in hospital wards was 156.91±27.78. Whether the hospital had carried out nursing human caring pilot(demonstration) wards, whether the ward had previously been a hospital nursing human caring pilot(demonstration) nursing unit, the type of ward, and whether nursing managers had participated in human caring training were the influencing factors of the implication of nursing humanistic caring in wards( P<0.05). Conclusions:The practice of nursing human caring in hospital wards is at a good level, but needs to be further strengthened. Nursing managers should take systematically strategies to promote the development of nursing human caring practice.

BACKGROUND/OBJECTIVES: Previous research has shown maternal betaine supplementation alleviates fetal-derived hepatic steatosis. Therefore, this study examined the anti-inflammatory effect of maternal betaine intake in offspring mice and its mechanism.MATERIALS/METHODS: Female C57BL/6J mice and their offspring were randomly divided into 3 groups according to the treatment received during gestation and lactation: control diet (CD), fatty liver disease (FLD), and fatty liver disease + 1% betaine (FLD-BET). The FLD group was given a high-fat diet and streptozotocin (HFD + STZ), and the FLD-BET group was treated with HFD + STZ + 1% betaine. After weaning, the offspring mice were given a normal diet for 5 weeks and then dissected to measure the relevant indexes. RESULTS: Compared to the CD group, the offspring mice in the FLD group revealed obvious hepatic steatosis and increased serum levels of alanine aminotransferase, interleukin (IL)-6, and tumor necrosis factor (TNF)-α; maternal betaine supplementation reversed these changes. The hepatic mRNA expression levels of IL-6, IL-18, and Caspase-1 were significantly higher in the FLD group than in the CD group. Maternal betaine supplementation reduced the expression of IL-1β, IL-6, IL-18, and apoptosis-associated speck-like protein containing C-terminal caspase recruitment domain (ASC). Maternal betaine supplementation also reversed the increasing protein expressions of nitric oxide dioxygenase-like receptor family pyrin domain containing 3 (NLRP3), ASC, Caspase-1, IL-1β, and IL-18 in offspring mice exposed to HFD + STZ. Maternal betaine supplementation decreased the homocysteine (Hcy) and s-adenosine homocysteine (SAH) levels significantly in the livers. Furthermore, the hepatic Hcy concentrations showed significant inverse relationships with the mRNA expression of TNF-α, NLRP3, ASC, and IL-18. The hepatic SAH concentration was inversely associated with the IL-1β mRNA expression. CONCLUSIONS The lipotropic and anti-inflammatory effect of maternal betaine supplementation may be associated with the inhibition of NLRP3 inflammasome in the livers of the offspring mice.

From June 2015 to June 2020, 52 patients who underwent emergency gastroscopy and treatment for upper gastrointestinal bleeding after percutaneous coronary intervention (PCI) at the Renmin Hospital of Wuhan University were included and retrospectively analyzed. The etiologic diagnosis of bleeding, results of hemostatic treatment and occurrence of complications during the emergency gastroscopy were observed. Among the 52 patients, 47 cases (90.4%) were found to have lesions that could explain upper gastrointestinal bleeding under emergency gastroscopy, and the remaining 5 cases (9.6%) could not clearly diagnose the cause of bleeding. Twenty-six cases (50.0%) were treated with emergency endoscopic hemostasis, of which 25 cases (96.2%) were successful. The median time for emergency endoscopy was 18 min. Seven cases (13.5%) had transient slowing of heart rate and lowering of blood pressure without serious complications. This shows that emergency gastroscopy is safe and effective in the diagnosis and treatment of upper gastrointestinal bleeding combined with post-PCI.
