ObjectiveBased on literature data mining， this study explores the modeling elements of diarrhea-predominant irritable bowel syndrome （IBS-D） animal models in China and abroad， providing references and suggestions for improving modeling methods and evaluation indicators. MethodsRelevant literature on IBS-D animal experiments from 2014 to 2024 was retrieved through computer searches in databases such as China National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP， Chinese Medical Journals Full-text Database， and PubMed. Information on experimental animal species， gender， body weight， modeling methods， modeling periods， intervention controls， modeling standards， and detection indicators was organized. Microsoft Excel 2021 software was used to establish a database and perform statistical analysis to examine the characteristics of IBS-D animal models. ResultsA total of 398 articles that met the inclusion criteria were reviewed. The IBS-D animal models were predominantly established using SD rats， Wistar rats， and C57BL/6 mice. Male animals were more commonly used， with rats typically aged 6-8 weeks and mice aged 4-6 weeks. In terms of interventions， piverium bromide was the main Western medicine， Tongxieyaofang was the primary Chinese medicine， and electroacupuncture was the primary acupuncture method. Among the modeling methods， the multi-factor combined composite modeling approach was the most common. Modeling periods were mainly concentrated between 1-14 days and 15-30 days. The success criteria for modeling were mainly evaluated based on the animal's general condition， fecal appearance， visceral sensitivity， gastrointestinal motility， behavior， and pathology. Detection indicators included apparent indexes， pathological markers， biochemical indicators， oxidative stress， brain-gut peptides， neurotransmitters， inflammatory factors， immune function， intestinal permeability， autophagy， apoptosis， proteins related to relevant signaling pathways， intestinal microbiota and its metabolites， etc. ConclusionThere are various methods for establishing IBS-D animal models， but no unified and universally accepted method has been established. The operation of the same modeling methods and the evaluation standards of the models vary across studies. Based on the results of data mining， the authors suggest that the multi-factor combined composite modeling approach most closely reflects the pathophysiological processes of IBS-D， better simulating the complex clinical symptoms of IBS-D patients， such as abdominal pain and diarrhea， and has a high degree of clinical relevance. This method is relatively recommended. While animal models in general align with Western medicine standards， models incorporating traditional Chinese medicine （TCM） syndromes are relatively few. Therefore， one of the future directions for research is to establish IBS-D animal models that meet the combined clinical disease and syndrome requirements of both Western and Chinese medicine.

OBJECTIVE To provide reference for rational clinical use of immune checkpoint inhibitor （ICI）. METHODS Electronic medical record information of patients who received ICI treatment from January 1st 2020 to December 31st 2023 at a certain hospital was collected. Patients were divided into thyroid immune-related adverse event （irAE） group （subdivided into clinical hypothyroidism， clinical hyperthyroidism， subclinical hypothyroidism， and subclinical hyperthyroidism subgroups） and non- thyroid irAE group based on whether they experienced immune-induced thyroid irAE. Univariate and multivariate Logistic regression analyses were employed to analyze the influencing factors of ICI-related thyroid adverse events. RESULTS A total of 382 patients who received ICI treatment were included， with 137 cases in the thyroid irAE group （accounting for 35.9%） and 245 cases in the non-thyroid irAE group （accounting for 64.1%）. Multivariate Logistic regression analysis， following univariate screening， revealed that ICI combined with radiotherapy was positively associated with the occurrence of thyroid irAE [odds ratio （OR）＝2.157， 95% confidence interval （CI） （1.144， 4.066）， P＜0.05]， while lung squamous cell carcinoma was negatively associated with the occurrence of thyroid irAE [OR＝0.600， 95%CI （0.369， 0.975）， P＜0.05]. Among various thyroid irAE， nasopharyngeal malignancy was positively associated with the occurrence of immune-related clinical hyperthyroidism [OR＝4.678， 95%CI （1.149， 19.042）， P＜0.05]； ICI combined with radiotherapy [OR＝2.622， 95%CI （1.227， 5.603）， P＜0.05] and lung adenocarcinoma [OR＝2.013， 95%CI （1.078， 3.759）， P＜0.05] were positively associated with the occurrence of immune-related subclinical hyperthyroidism. Age was negatively associated with the occurrence of immune-related clinical hypothyroidism [OR＝0.944， 95%CI （0.896， 0.995）， P＜0.05]； age [OR＝0.963， 95%CI （0.932， 0.994）， P＜0.05] and ICI combined with chemotherapy [OR＝0.332， 95%CI （0.137， 0.802）， P＜0.05] were negatively associated with the occurrence of immune-related subclinical hypothyroidism. CONCLUSIONS Among patients receiving ICI treatment， younger patients are more prone to thyroid irAE. Patients receiving ICI combined with chemotherapy are less likely to experience subclinical hypothyroidism， while ICI combined with radiotherapy significantly increases the risk of thyroid adverse events.

Objective To observe the changes of memory function in patients with mild traumatic brain injury(mTBI),and to explore the correlation between functional connection(FC)changes and montreal cognitive assessment(MoCA)scale scores in the mTBI cohort.Methods Thirty-nine patients with acute mTBI and 39 healthy controls were prospectively collected.All subjects underwent rs-fMRI scans,and FC values were calculated in both groups.Results Compared with healthy controls,the FC of the left posterior cingulate cortex,the left cuneus and the right calcarine fissure were enhanced.The FC of the left orbital superior frontal gyrus with the right superior temporal gyrus and the right postcentral gyrus was enhanced,and the FC of the right parahippocampal gyrus with the right medial and lateral cingulate gyrus,right thalamus and right caudate nucleus was weakened.Correlation analysis showed that there was no significant correlation between MoCA scale score and FC based on DMN network nodes.Conclusion The DMN network was damaged in patients with acute mTBI,and the memory function was impaired.In addition,no correlation was found between FC abnormalities and MoCA scale scores in this study

Bisecting N-acetylglucosamine(GlcNAc),a GlcNAc linked to the core β-mannose resi-due via a β1,4 linkage,is a special type of N-glycosylation that has been reported to be involved in various biological processes,such as cell adhesion and fetal development.This N-glycan structure is abundant in human trophoblasts,which is postulated to be resistant to natural killer cell-mediated cytotoxicity,enabling a mother to nourish a fetus without rejection.In this study,we hypothesized that the human amniotic membrane,which serves as the last barrier for the fetus,may also express bisected-type glycans.To test this hypothesis,glycomic analysis of the human amniotic membrane was performed,and bisected N-glycans were detected.Furthermore,our pro-teomic data,which have been previously employed to explore human missing proteins,were ana-lyzed and the presence of bisecting GlcNAc-modified peptides was confirmed.A total of 41 glycoproteins with 43 glycopeptides were found to possess a bisecting GlcNAc,and 25 of these gly-coproteins were reported to exhibit this type of modification for the first time.These results provide insights into the potential roles of bisecting GlcNAc modification in the human amniotic membrane,and can be beneficial to functional studies on glycoproteins with bisecting GlcNAc modifications and functional studies on immune suppression in human placenta.

Background and Objectives: Systemic scleroderma (SSc) is a rare and serious connective tissue disease, an autoimmune disease, and a rare refractory disease. In this study, preventive effect of single systemic human umbilical cord mesenchymal stem cells (UC-MSCs) transfusion on SSc was preliminarily explored. Methods: and Results: SSc mouse model was established by daily intradermal injection of Hypochlorite (HOCl). SSc mice were treated by single transfusion of UC-MSCs at 0.625×10 5 , 2.5×105 and 1×106 respectively. At the 42nd day of intradermal injection of HOCl, the symptoms showed up by skin and alveolar wall thickening, lymphocytic infiltration, increased collagen in skin/lung, and the increased proportion of CD3 ＋ CD4＋ CD25＋ FoxP3＋ cells (a Treg subset) in spleen. After UC-MSCs transfusion, the degree of skin thickening, alveolar wall thickening and lymphocyte infiltration were decreased, the collagen sedimentation in skin/lung was decreased, and the proportion of CD3＋ CD4＋ CD25＋FoxP3＋ cells was decreased. Conclusions UC-MSC can achieve a preventive effect in SSc mice by fibrosis attenuation and immunoregulation.

Coronavirus disease 2019(COVID-19),which is caused by SARS-CoV-2,varies with regard to symptoms and mortality rates among populations.Humoral immunity plays critical roles in SARS-CoV-2 infection and recovery from COVID-19.However,differences in immune responses and clinical features among COVID-19 patients remain largely unknown.Here,we report a database for COVID-19-specific IgG/IgM immune responses and clinical parameters(named COVID-ONE-hi).COVID-ONE-hi is based on the data that contain the IgG/IgM responses to 24 full-length/truncated proteins corresponding to 20 of 28 known SARS-CoV-2 proteins and 199 spike protein peptides against 2360 serum samples collected from 783 COVID-19 patients.In addition,96 clinical parameters for the 2360 serum samples and basic information for the 783 patients are integrated into the database.Furthermore,COVID-ONE-hi provides a dashboard for defining samples and a one-click analysis pipeline for a single group or paired groups.A set of samples of interest is easily defined by adjusting the scale bars of a variety of parameters.After the"START"button is clicked,one can readily obtain a comprehensive analysis report for further interpretation.COVID-ONE-hi is freely available at www.COVID-ONE.cn.

Chloroquine (CQ) phosphate has been suggested to be clinically effective in the treatment of coronavirus disease 2019 (COVID-19). To develop a physiologically-based pharmacokinetic (PBPK) model for predicting tissue distribution of CQ and apply it to optimize dosage regimens, a PBPK model, with parameterization of drug distribution extrapolated from animal data, was developed to predict human tissue distribution of CQ. The physiological characteristics of time-dependent accumulation was mimicked through an active transport mechanism. Several dosing regimens were proposed based on PBPK simulation combined with known clinical exposure-response relationships. The model was also validated by clinical data from Chinese patients with COVID-19. The novel PBPK model allows in-depth description of the pharmacokinetics of CQ in several key organs (lung, heart, liver, and kidney), and was applied to design dosing strategies in patients with acute COVID-19 (Day 1: 750 mg BID, Days 2-5: 500 mg BID, CQ phosphate), patients with moderate COVID-19 (Day 1: 750 mg and 500 mg, Days 2-3: 500 mg BID, Days 4-5: 250 mg BID, CQ phosphate), and other vulnerable populations (.., renal and hepatic impairment and elderly patients, Days 1-5: 250 mg BID, CQ phosphate). A PBPK model of CQ was successfully developed to optimize dosage regimens for patients with COVID-19.

Objective:To evaluate the optimized effect of erector spinae plane block (ESPB) combined with general anesthesia when used for the patients undergoing laparoscopic pancreaticoduodenectomy.Methods:Sixty-eight American Society of Anesthesiologists physical status Ⅱ orⅢ patients of both sexes, aged 18-64 yr, with body mass index of 18-24 kg/m 2, scheduled for elective laparoscopic pancreaticoduodenectomy, were divided into general anesthesia group (group G, n=34) and ESPB combined with general anesthesia group (group EG, n=34) using a random number table method.In group E, ultrasound-guided ESPB was performed before induction with general anesthesia, and 0.375% ropivacaine 20 ml was injected into both sides.Total intravenous anesthesia was applied in both groups.Patient-controlled intravenous analgesia (PCIA) with sufentanil 1.5 g/kg in 100 ml of normal saline was performed after surgery.The PCIA pump was set up to deliver a 2 ml bolus dose with a 5-min lockout interval and background infusion at 3 ml/h.Analgesia was performed until 24 h after operation, and the visual analogue scale score at rest was maintained at ≤4.Sufentanil 0.1 g/kg was intravenously injected as rescue analgesic when visual analogue scale score >4.The extubation time and occurrence of intraoperative cardiovascular events were recorded.The amount of sufentanil used during operation and within 24 h after operation was recorded.The time to first pressing the analgesia pump after operation and effective pressing times of PCA within 24 h after operation were recorded.Time to first flatus, first ambulation time and length of postoperative hospital stay were recorded.The development of postoperative adverse reactions such as nausea and vomiting, irritability and respiratory depression within 24 h after operation was recorded. Results:Compared with group G, the incidence of intraoperative hypertension and tachycardia was significantly decreased, the extubation time was shortened, the consumption of sufentanil during operation and within 24 h after operation was reduced, the time to first pressing the analgesia pump was prolonged, the effective pressing times of PCA within 24 h after operation were reduced, time to first flatus, first ambulation time and length of postoperative hospital stay were shortened, and the incidence of nausea and vomiting, irritability and respiratory depression within 24 h after operation was decreased in group EG ( P<0.05). Conclusion:The combination of ESPB and general anesthesia is helpful in achieving an anesthesia mode of lower opioid consumption and more helpful for inhibition of postoperative pain responses and for early postoperative recovery than general anesthesia alone when used for the patients undergoing laparoscopic pancreaticoduodenectomy.
