ObjectiveTo explore the potential mechanism of Xiaoqinglongtang（XQL） in the prevention and treatment of high altitude pulmonary edema（HAPE） by network pharmacology， molecular docking， and molecular dynamics simulation， and to verify it by in vivo animal model. MethodsIn this study， the active ingredients， drug targets， and HAPE-related targets of XQL were collected from BATMAN-TCM， GeneCards， and Online Mendelian Inheritance in Man（OMIM） databases. The protein-protein interaction（PPI） network was constructed by using intersection targets， and the core targets were screened and visualized by Cytoscape software. Functional annotation and pathway analysis of the intersection targets were performed by gene ontology （GO） and Kyoto encyclopedia of genes and genomes （KEGG） functional enrichment. AutoDock and GROMACS were used to evaluate the binding ability of active ingredients to key targets. In the experimental verification part， a mouse model of HAPE induced by hypobaric hypoxia（simulated 6 000 m altitude for 48 h） was established. The control effect was evaluated by hematoxylin-eosin（HE） staining， lung tissue water content， lung tissue wet/dry weight ratio， real-time quantitative polymerase chain reaction（Real-time PCR） detection of gene expression levels， and immunohistochemistry and Western blot detection of key protein expression. ResultsA total of 355 active ingredients of XQL， 2 142 targets， 716 HAPE-related targets， and 236 intersection targets were obtained by network pharmacology analysis. Key core targets such as interleukin （IL）-6， tumor necrosis factor （TNF）， protein kinase B1 （Akt1）， and hypoxia-inducible factor-1α （HIF-1α） were screened. The results of GO analysis of common targets involved 738 biological processes（BP）， 72 cellular components（CC）， and 135 molecular functions（MF）. KEGG analysis effectively enriched two important signaling pathways： Phosphoinositol 3-kinase （PI3K）/Akt and HIF-1α. The results of molecular docking and molecular dynamics simulation showed that the screened active ingredients had good binding ability with key targets. In the HAPE model induced by hypobaric hypoxia（6 000 m， 48 h）， the lung tissue water content， lung tissue wet/dry weight ratio， and pathological injury score of the model group were significantly increased（P<0.01）， accompanied by exudation of a large number of red blood cells in the alveoli and alveolar interstitium， a significant increase in inflammatory cells， a significant widening of the alveolar septum， and mutual fusion between the alveoli. The XQL administration group significantly improved the above pathological changes（P<0.01）. The results of inflammatory factor expression showed that compared with the control group， the model group showed significantly up-regulated expression of TNF-α， IL-6， and IL-1β in the lung tissue（P<0.01）. Compared with the model group， the XQL administration group had significantly decreased expression of inflammatory factors（P<0.05， P<0.01）. The mRNA expression of key pathway related genes PI3K， Akt1， mammalian target of rapamycin（mTOR）， and HIF-1α was significantly increased in the model group（P<0.01）， and decreased in a concentration-dependent manner after XQL administration（P<0.05， P<0.01）. The expression levels of key proteins PI3K， phosphorylation（p）-PI3K， Akt1， p-Akt1， mTOR， p-mTOR， and HIF-1α in lung tissue were analyzed by immunohistochemistry and Western blot. Compared with the blank group， the model group showed increased expression of key proteins（P<0.05， P<0.01）. Compared with the model group， the XQL administration group exhibited decreased expression of key proteins（P<0.05， P<0.01）. ConclusionXQL can reduce lung inflammation and improve HAPE. The mechanism may be related to the regulation of PI3K/Akt/mTOR and HIF-1α pathways. This study provides a new idea and a theoretical basis for the treatment of HAPE with XQL.

Background: and Purpose Live cell-based assays (LCBA) are increasingly used for serological antibody detection due to their ability to preserve antigen conformation, offering moderately higher sensitivity than fixed cell-based assays. However, the clinical necessity of prioritizing LCBA for the detection of aquaporin-4 immunoglobulin G (AQP4-IgG) in neuromyelitis optica spectrum disorder (NMOSD) remains unclear, especially when compared to its established role in diagnosing myelin oligodendrocyte glycoprotein antibody-associated disease. Methods: We compared the performance of live cell-based assays using immunofluorescence (LCBA-IF) and fixed cell-based assays using immunofluorescence (FCBA-IF) in detecting AQP4-IgG in 90 cases of NMOSD meeting 2015 International Panel for Neuromyelitis Optica Diagnosis criteria, alongside 40 controls. Additionally, we further investigated the relationship between AQP4-IgG titers as measured by LCBA-IF and FCBA-IF and clinical parameters in NMOSD patients. Results: Results showed 96.9% agreement between LCBA-IF and FCBA-IF (Cohen’s κ=0.935), with a strong Spearman correlation (0.977, p<0.001). Both methods demonstrated 100% specificity, with LCBA-IF showing slightly higher sensitivity compared to FCBA-IF. Within LCBAIF-tested groups, statistically significant differences in annualized relapse rates were observed across all pairwise comparisons (low-titer vs. moderate-titer, low-titer vs. high-titer, and moderate-titer vs. high-titer; all p<0.050). However, this association reached statistical significance in some FCBA-IF-tested groups. Conclusions Overall, there is a strong concordance between LCBA-IF and FCBA-IF in detecting AQP4-IgG, where LCBA-IF shows slightly higher sensitivity. Furthermore, there is a potential link between elevated AQP4-IgG titers and an increased risk of relapse, and this correlation may appear more pronounced when using LCBA-IF.

Objective To translate the Maternal Childbirth Fatigue Perception Questionnaire(MCFQ)into Chinese and examine its reliability and validity among women undergoing vaginal deliv-ery.Methods Following the Brislin translation model,the MCFQ was translated,back-translated,culturally adapted and pre-tested to develop a Chinese version.By using the convenience sampling method,574 parturients were selected for a questionnaire survey from January to April 2024,and the reliability and validity of the Chinese questionnaire were evaluated.Results The Chinese version of MCFQ consisted of 3 dimensions and 13 items,namely physical fatigue(7 items),perceived fatigue(3 items)and emotional fatigue(3 items).The item-level content validity index ranged from0.813 to 1.000,and the scale-level content validity index was 0.938.The overall Cronbach's α coefficient of the scale was 0.870,and the split-half reliability coefficient was 0.848.Confirmatory factor analysis demonstrated that the question naire had a good fit.Conclusion The Chinese version of MCFQ has good reliability and validity and can be used as an effective tool to assess the fatigue level of parturients during the delivery process.It is helpful for clinical medical staff to optimize the management of the la-bor process,improve the quality of delivery,and ensure the safety of mothers and infants.

Objective:Systematic evaluation and integration of the real experience of dietary restriction in patients with inflammatory bowel disease, providing reference for the development of targeted intervention strategies.Methods:Qualitative studies on the dietary restriction experience of patients with inflammatory bowel disease retrieved from PubMed, Cochrane Library, Web of Science, Embase, CINAHL, China National Knowledge Infrastructure, Wanfang, VIP, and Chinese Biomedical Literature Database using computer search. The search period was from the establishment of the database to May 31, 2024. According to the Australian Joanna Briggs Institute Evidence Based Healthcare Center Qualitative Research Quality Evaluation Criteria, the quality of included literature was evaluated, and the results were subjected to meta-analysis using a pooled integration method.Results:A total of 9 studies were included, and 36 research results were extracted and summarized into 9 categories. Then, three integrated results were further synthesized, namely physical and mental impairment and social limitation; change attitude and actively explore; seeking external support to promote beneficial growth.Conclusions:Dietary restrictions for inflammatory bowel disease have various impacts on patients. Medical staff should focus on the nutritional status and emotional needs of patients, and provide multidimensional social support based on their actual dietary management experience. They should develop patient-centered personalized intervention measures to help patients achieve more scientific and effective dietary management and improve their overall quality of life.

Objective To systematically analyze the changes in clinical indicators including blood leukocytes and neutrophils,liver and kidney functions,coagulation function,lipids,and levels of thyroid hormones and antibodies in Graves'ophthalmopathy(GO)patients who had undergone effective treatment with tocilizumab(TCZ)and to explore their clinical significance.Methods Eighty-five patients with moderately or severely active GO who were effectively treated with TCZ were enrolled.Early morning fasting blood was collected and tested for routine blood,biochemical routine,coagulation function,thyroid hormone and antibodies,and basic information such as gender,age,duration of the disease,history of smoking,comorbidities,and medications were also collected from all patients,so changes in the clinical indicators before and after the treatment could be analyzed and correlation analyses could be carried out.Results Patients with moderately to severely active GO treated with TCZ showed a significant decrease in absolute blood leukocyte and neutrophil values compared with before,and a significant decrease in liver function(alanine transaminase,aspartate aminotransferase,creatinine),cholesterol(total cholesterol,high-density lipoprotein and low-density lipoprotein)levels were significantly higher than before,and concentrations of coagulation parameters[prothrombin time,activated partial thromboplastin time,fibrinogen(FIB)and D-dimer]were significantly decreased.The concentrations of thyroid hormone and thyroid-stimulating hormone levels increased significantly,and the antibody titer of thyrotropin receptor antibody(TRAB)was significantly down-regulated after treatment.TRAB levels were significantly correlated with FIB before treatment.Conclusion Thyroid function and antibody levels improved after TCZ treatment in patients with moderately to severely active GO,but blood leukocytes,liver function and coagulation function changed significantly compared with before.The results of this study confirm the therapeutic effect of TCZ on immune disorders in GO ophthalmopathy,while underscoring the importance of monitoring potential adverse effects in clinical treatment.

Objective To evaluate drug-related problems(DRPs)and to analyze the influencing factors of patients un-dergoing video-assisted thoracoscopic surgery(VATS)before operation in thoracic surgery.Methods Clinical pharmacists used the Pharmaceutical Care Network Europe(PCNE)classification system(version 9.1)to analyze DRPs and influencing fac-tors of patients who received VATS from March 1 to May 31,2023,and had at least one comorbidity.Results Out of 300 pa-tients,174 were involved in a total of 200 DRPs.The most common category of DRPs is treatment safety(47.50％),followed by treatment effectiveness(46.00％)and others(6.50％).The most common cause of the problem is drug selection(33.83％),fol-lowed by other(33.33％)and patient cause(19.90％).367 interventions were conducted for DRPs,with the most interventions being at the drug level(55.86％),followed by the doctor level(39.24％)and the patient level(3.54％).In the end,96.00％of the intervention plan was accepted,and 86.50％of the problems were resolved.There were significant differences(P＜0.05)in the number of underlying diseases,medication varieties,body mass index(BMI),and length of hospital stay between the group with and without DRPs.The results of multivariate analysis showed that comorbidities,number of medication types,and BMI were independent risk factors for preoperative occurrence(or potential)of DRPs in VATS patients in thoracic surgery(OR＞1,P＜0.05).Conclusions Clinical pharmacists can effectively evaluate preoperative DRPs in patients undergoing VATS in thoracic surgery through the PCNE classification system.Comorbidities,number of medications,and BMI are influential factors for the oc-currence of preoperative DRPs.Future clinical practice should focus on these risk factors to optimize treatment strategies and re-duce the occurrence of DRPs.

The incidence and mortality rates of hepatocellular carcinoma(HCC)remain high in China,and the application of surgical resection is often limited due to the fact that most patients are in the advanced stage at the time of confirmed diagnosis.This article reviews commonly used advanced locoregional therapies for HCC and the advances in mainstream techniques such as local ablation(radiofrequency ablation,microwave ablation,irreversible electroporation,and cryoablation),intravascular intervention(transcatheter arterial chemoembolization,hepatic arterial infusion chemotherapy,and Y90 hepatic arterial infusion chemotherapy),and radiotherapy(CyberKnife,proton therapy,and heavy-ion therapy),and a multidimensional decision-making framework is constructed for HCC locoregional therapy by comparing treatment principles,indications,limitations,and clinical data of these techniques.This article aims to provide evidence-based support for persistent dilemmas in clinical decision-making,promote the role of locoregional therapies in clinical practice,and propose the directions for future research and clinical application.This article also establishes a comprehensive clinical roadmap for HCC locoregional therapy,which helps to address current challenges regarding technique selection and delineate future directions for innovation,in order to reshape the treatment of HCC through technological integration and paradigm innovation.
