Objective To investigate the biological function and potential mechanisms of long non-coding RNA(lncRNA)neurensin 2-antisense RNA 1(NRSN2-AS1)in liver cancer cells.Methods The Encyclopedia of RNA Interactomes(ENCORI)database was used to analyze the expression levels of NRSN2-AS1 in liver cancer tissues and normal tissues as well as its association with the prognosis of patients.Stable lncRNA NRSN2-AS1 cell lines,overexpressed or knockdown,were constructed.The effects of NRSN2-AS1 on tumor cell proliferation were explored using CCK-8 and colony formation assays.Transwell and wound healing assays were employed to examine the role of NRSN2-AS1 in tumor cell migration and invasion.The impact of NRSN2-AS1 on tumor cell aerobic glycolysis was assessed by measuring hexokinase activity,glucose uptake,ATP and etracellular lactate levels.Quantitative real-time PCR(qPCR)and Western blotting were used to evaluate the effects of NRSN2-AS1 on the mRNA and protein expression levels of hexokinase 2(HK2)in tumor cells.Results Analysis from the ENCORI database revealed that NRSN2-AS1 was upregulated in liver cancer tissues compared to normal tissues,and that high expressions of NRSN2-AS1 were closely associated with poor prognosis of patients.In vitro functional assays demonstrated that overexpression of NRSN2-AS1 promoted proliferation,migration,and invasion of liver cancer cells,and enhanced glycolysis levels while knockdown of NRSN2-AS1 inhibited these processes and suppressed glycolysis.Furthermore,overexpression of NRSN2-AS1 increased the mRNA and protein levels of HK2 while knockdown of NRSN2-AS1 decreased HK2 expression in liver cancer cells.Conclusion NRSN2-AS1 is highly expressed in liver cancer tissues,and it may promote liver cancer progression by enhancing HK2 expression and aerobic glycolysis.

ObjectiveTo evaluate the efficacy and safety of acupoint application for post-stroke depression (PSD) by regulating gastrointestinal function. A secondary objective is to explore the potential mechanism underlying this approach from the perspective of gut microbiota.MethodsThis multicenter, randomized, double-blind (patients and assessors), placebo-controlled trial will enroll 80 patients with PSD, and include a 1-week run-in period, a 4-week treatment phase, and a 12-week follow-up. Eligible participants will randomly be assigned in a 1:1 ratio to either the acupoint application or placebo (non-acupoint) groups. Treatments will be administered thrice weekly for 4 weeks. The primary outcome is change in the Hamilton Rating Scale for Depression (HAMD) score. Secondary outcomes include the Beck Depression Inventory (BDI), 36-Item Short-Form Health Survey (SF-36), Barthel Index of Activities of Daily Living, Social Adaptation Self–Evaluation Scale (SASS), and gut microbiota profiling. All outcomes will be assessed at baseline (prior to treatment), during treatment (weeks 2 and 4), and during follow-up (weeks 8, 12, and 16). The Treatment Emergent Symptom Scale (TESS) will be used for evaluation throughout the 4-week treatment phase.DiscussionThe results of this study will provide important evidence supporting a novel treatment strategy for PSD that targets gastrointestinal regulation, potentially informing future clinical practice.

Objective:To screen broadly neutralizing antibodies in human immunodeficiency virus-1（HIV-1）chronically infected individuals and characterize their molecular features and to provide new strategies for rational vaccine development and antibody-based therapeutics.Methods:A total of 34 treatment-na?ve individuals with chronic HIV-1 infection were enrolled. Plasma antibody binding levels were measured against two HIV-1 envelope proteins. Single antigen-specific memory B cells were sorted from high-binding samples，and antibody variable region genes were amplified by PCR for paired expression. The monoclonal antibodies were evaluated for neutralizing activity using pseudovirus assays，and their structural features were analyzed by integrating AlphaFold 3 prediction with Discovery Studio molecular docking.Results:Plasma samples showed strong binding to DU422-GP140 and BG505-GP140. Eight monoclonal antibodies were isolated from two donors. Among them，antibodies 0919-A4，0919-A9 and 0808-A2 could cross-react with GP140 from HIV-1 subtypes AE，BC and B. The monoclonal antibody 0919-A9 demonstrated potent neutralizing activity against SF162（Tier 1）and CH181（Tier 2）pseudoviruses，with somatic hypermutation rates of 13.27%（heavy chain）and 15.58%（light chain）. Structural modeling revealed its specific targeting of the V1V2 region on GP120.Conclusion:The isolated antibody 0919-A9 effectively neutralizes Tier 2 pseudoviruses. Its high somatic mutation frequency and V1V2-targeting property underlie its neutralizing activity，providing both a promising candidate and mechanistic insights for HIV vaccine development and antibody-based therapeutic strategies.

Objective:To assess the effect of transversus abdominis plane block (TAPB) with liposomal bupivacaine and general anesthesia on postoperative delirium (POD) in elderly patients with prior novel coronavirus pneumonia (COVID-19).Methods:In this randomized double-blind controlled study, 416 patients of either sex, aged 65-90 yr, weighing 50-90 kg, of American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ, diagnosed as having COVID-19 within 6 months prior to surgery, who underwent laparoscopic colorectal cancer surgery under combination of elective TAPB and combined intravenous-inhalational general anaesthesia at Qingdao Municipal Hospital from June 2023 to December 2024, were selected. The patients were divided into liposomal bupivacaine group ( n=208) and bupivacaine hydrochloride group ( n=208) using the random number table method. After induction of anaesthesia, bilateral TAPB was performed with liposomal bupivacaine injectio 266 mg (40 ml) in liposomal bupivacaine group and with 0.5% bupivacaine hydrochloride 40 ml in bupivacaine hydrochloride group. The primary outcome measure was the occurrence of POD within 7 days after surgery. Secondary outcome measures included severity of POD, pain scores at 24, 48 and 72 h after operation, the rate of postoperative rescue analgesia and consumption of morphine, duration of post-anesthesia care unit stay, and length of hospital stay. The occurrence of complications such as death, reoperation, atelectasis and pneumonia was recorded at 30 days after surgery. Results:Compared with bupivacaine hydrochloride group, the incidence of POD was significantly decreased (21.5% [43/200]versus 12.0% [24/200]), pain scores at 24, 48 and 72 h after operation were decreased, the rate of postoperative rescue analgesia and consumption of morphine were decreased, and the duration of post-anesthesia care unit stay and length of hospital stay were shortened in liposomal bupivacaine group ( P<0.05). There was no significant difference in the severity of POD and the case fatality rate and related complications within 30 days after surgery between the two groups ( P>0.05). Conclusions:Liposomal bupivacaine TAPB combined with general anesthesia can reduce the development of POD in elderly patients with prior COVID-19.

Objective:To evaluate the relationship between preoperative concentrations of soluble triggering receptor expressed on myeloid cells 2 (sTREM2) in cerebrospinal fluid (CSF) and postoperative delirium (POD) in patients undergoing total knee/hip arthroplasty.Methods:Six hundred and twenty-five patients of either sex, aged 50-90 yr, weighing 50-80 kg, with American Society of Anesthesiologists Physical Status classification Ⅰor Ⅱ, with the preoperative Mini-Mental State Examination score > 23, who underwent elective knee/hip arthroplasty under combined spinal-epidural anesthesia at Qingdao Municipal Hospital from January 2022 to December 2023, were selected. The CSF specimens 2 ml were withdrawn from the subarachnoid space after successful subarachnoid puncture for determination of the concentrations of sTREM2, Amyloid beta protein (Aβ 42), total tau protein (T-tau), and phosphorylated tau protein (p-tau) by enzyme-linked immunosorbent assay. POD was assessed using the Confusion Assessment Method. Patients were divided into POD group and non-POD group based on whether POD occurred. Logistic regression was used to identify the risk and protective factors for POD. The performance of CSF sTREM2 concentration combined with CSF biomarker levels in predicting POD was evaluated using the receiver operating characteristic (ROC) curve and clinical decision curve. The mediating effect of CSF biomarker concentrations in the relationship between CSF sTREM2 concentration and POD was analyzed. Results:Five hundred and nineteen patients were finally included, with 112 patients in POD group and 407 patients in non-POD group. The results of logistic regression analysis showed that the elevated preoperative sTREM2 concentration in CSF was the risk factor for POD after adjusting for multiple confounding factors such as age, sex, body mass index, years of education, Mini-Mental State Examination score, history of smoking, history of drinking, hypertension, diabetes mellitus and coronary heart disease. The area under the ROC curve of the preoperative sTREM2 concentration in CSF in predicting POD was 0.716, and the area under the ROC curve of the preoperative sTREM2 concentration in CSF combined with CSF biomarkers in predicting POD was 0.796. This model had high clinical application value and predictive efficacy. The relationship between the preoperative sTREM2 concentration in CSF and POD was partially mediated by the CSF p-tau concentration (proportion of mediated effect 24.67%) and t-tau protein concentration (proportion of mediated effect 17.33%).Conclusions:The elevated preoperative concentration of sTREM2 in CSF is a risk factor for POD in patients undergoing total knee/hip arthroplasty, and concentrations of t-tau and p-tau in CSF play a mediating role in the relationship between the preoperative CSF sTREM2 concentration and POD.
