The sepsis and sepsis-induce lung inju-ry threats seriously human health.Dexmedetomi-dine(DEX),a sedative drug,plays an active role in preventing sepsis-induced lung injury during the ba-sic and clinical practice.The current article reviews the role and mechanism of DEX dexmedetomidine alleviating sepsis-induced lung injury from the as-pects of inflammation,oxidative stress,apoptosis,mitochondrial dynamics,autophagy,vascular per-meability,neuro-regulation,targeting miR-128-3p/MAPK14 and DNA methylation,etc.This review looks forward to deepen the understanding the ap-plication of DEX in the field of critical care medi-cine,expand the pharmacological effect of DEX and provide a new idea for the prevention and treat-ment of sepsis from the sedation approach.

Depression,as a severe psychological and psychiatric disorder,significantly impairs the long-term physical and mental health of patients.Current depression detection methods are plagued by strong subjectivity,limited techniques,and inadequate intelligence.Previous studies have mostly relied on single-modal signal analysis,making it difficult to comprehensively reflect the multidimensional characteristics of depression.Based on the independently developed intelligent depression detection system,wearable devices are used to collect prefrontal dual-lead EEG signals,PPG signals,and single-lead ECG signals.Data from 30 patients with depression and 40 healthy controls are collected and analyzed.A multimodal depression recognition model named RBLF-Net is proposed,which integrates spatiotemporal features,weighted attention,and random forests to utilize the multi-signal features for depression recognition.The model exhibits superior performance in the five-fold cross-validation,achieving a classification accuracy of 81.43%,a precision of 81.02%,and a recall rate of 81.25%,outperforming other comparative models,and thus providing an intelligent analysis approach for depression recognition from the perspective of multi-modal fusion.

Objective To compare the efficacy of electroacupuncture in traditional Chinese medicine with the opioid adjuvant drug dezocine.Methods 122 patients undergoing elective laparoscopic cholecystectomy at the Second Affiliated Hospital of Kunming Medical University between October 12,2023,and April 05,2024,were randomly allocated into three groups:dezocine group(D group,n=40),electroacupuncture group(E group,n=42),and electroacupuncture combined with dezocine group(ED group,n=40).Patients received 10 mg dezocine,electroacupuncture,or electroacupuncture+10 mg dezocine after cholecystectomy.Pain threshold index(PTi),pain index(Pi),and visual analogue scale(VAS)scores were observed at different time points during surgery.Vital signs were recorded,and adverse reactions within 24 hours postoperatively were noted.Results There were no statistically significant differences in PTi among groups before electroacupuncture(T1)(P>0.05).At the end of electroacupuncture(T2)and after cholecystectomy(T3),the PTi values in the E and ED groups were lower than the D group(P<0.05).At the end of surgery(T4)and upon extubation(T5),the PTi values of all three groups reached a tolerable level for patients,with the E and D groups showing higher PTi values compared to the ED group(P<0.05).There were no statistically significant differences in postoperative pain scores(Pi)and VAS at various time points(P>0.05).Conclusion Electroacupuncture demonstrates analgesic efficacy non-inferior to opioid drugs and can be recommended as a postoperative pain management technique for laparoscopic cholecystectomy patients.

Plasmablastic lymphoma (PBL) is a rare, highly aggressive non-Hodgkin lymphoma subtype for which no standardized therapeutic regimen has been established in clinical practice. This study retrospectively analyzed 18 PBL cases at Shanghai Ruijin Hospital from July 2012 to June 2024. Participants comprised 12 males and 6 females, with a median age of 59 (39–77) years. Twelve (66.7% ) cases presented at stage Ⅲ/Ⅳ, nine (50% ) have cytopenia, 12 (66.7% ) have increased lactate dehydrogenase level, and four (22.2% ) had a Ki-67 index of ≥90%. The tumor cells highly expressed CD38 (15/17, 88.2% ) /CD138 (12/17, 70.6% ), whereas the B-cell marker CD20 was rarely detected (1/17, 5.9% ). Of the 11 cases that underwent genetic sequencing, common mutations included TP53 (27.3% ), KMT2D (18.2% ), and TET2 (18.2% ). After excluding one patient with positive HIV who died without treatment, 17 patients received first-line therapy, achieving a complete response in 10 (58.8% ) and a partial response in 5 (29.4% ) cases. With the median follow-up time of 4.33 (0.17–12.17) years, Kaplan-Meier analysis indicated that the 2-year progression-free survival rate and overall survival rate were (68.5±11.2) % and (75.5±10.1) %, respectively.

Diabetic kidney disease(DKD)is one of the major complications of diabetes mellitus(DM),which significantly affects the survival and quality of life of DM patients.Currently,existing first-line treatment approaches for DKD are ineffective in effectively preventing the occurrence and progression of DKD.Traditional Chinese medicine(TCM)has the advantages of"ultiple pathways,multiple targets,and multiple mechanisms"in treating DKD,and has a broad prospect in the treatment of DKD.Aquaporin-2(AQP2)is a membrane channel protein widely expressed in the kidneys,and its physiological function is highly similar to the function of kidney filtration and reabsorption.Studies have found that various effective components and related formulae of Chinese medicine can improve symptoms in DKD patients by inhibiting the abnormal expression of AQP2.This article provides a review on the role of AQP2 in DKD and the research progress of TCM intervention,aiming to provide insights and references for the development of drugs related to the prevention and treatment of DKD.

Objective:To investigate the effect and mechanism of miR-217 targeted regulation of extracellular signal-regulated kinase 2(ERK2)expression on activity and immune escape of non-small cell lung cancer cells(NSCLC).Methods:qRT-PCR was used to detect expression levels of miR-217 and ERK2 mRNA in NSCLC tissues,adjacent tissues,and HLF-1,A549 and HCC827 cell lines.Analyzed prognosis and survival status of NSCLC patients with different miR-217 expression level.Bioinformatics and dual luciferase gene reporting experiments were used to analyze the targeting relationship between miR-217 and ERK2.Cultivated NSCLC A549 cells and divided them into NC group,miR-217 inhibitor group,miR-217 mimic group,miR-217 mimic+ERK2 NC group and miR-217 mimic+ERK2 group.Except for the NC group without any treatment,all other groups were transfected with corresponding plasmids to analyze the proliferation activity and immune escape status of A549 cells in each group,and clarified the mechanism of action.Results:Compared with adjacent tissues,expression of miR-217 in NSCLC tissue was decreased,while expression of ERK2 mRNA was increased(P<0.05).Compared with human normal lung fibroblast HLF-1 cell lines,expression of miR-217 in NSCLC cell lines A549 and HCC827 were decreased,while expression of ERK2 mRNA was increased(P<0.05).Analysis of the relationship be-tween miR-217 and prognosis of NSCLC patients based on Kaplan-Meier Plotter database showed that low expression of miR-217 was associated with poor prognosis of patients(HR=0.90,P=0.033).Dual fluorescein reporter genes showed matching sequences between the 3'UTR regions of miR-217 and ERK2.miR-217 mimic fragment could inhibit ERK2-WT signal,but had no effect on ERK2-MUT.Compared with NC group,cell proliferation activity,PD-L1 and PD-L2 mRNA expression levels of miR-217 inhibitor group were in-creased,while CD8+T cell activity was decreased,and cell proliferation activity,PD-L1 and PD-L2 mRNA expression levels of miR-217 mimic group were decreased,while CD8+T cell activity was increased(P<0.05).Compared with miR-217 mimic group,cell pro-liferation activity,CD8+T cell activity,PD-L1 and PD-L2 mRNA expression levels of miR-217 mimic+ERK2 NC group had no signifi-cant changes(P>0.05),cell proliferation activity,PD-L1 and PD-L2 mRNA expression levels of miR-217 mimic+ERK2 group were increased,while CD8+T cell activity was decreased(P<0.05).Conclusion:Overexpression of miR-217 can reduce the activity of NSCLC cell A549,inhibit the expression of PD-L1,activate CD8+T cells in tumor microenvironment,and then inhibit immune es-cape,which may play a role by targeting ERK2.
