Objective To investigate the expression characteristics, prognostic value, and correlation with immune infiltration of vasoactive intestinal peptide receptor 2 (VIPR2) in esophageal adenocarcinoma (ESAD). Methods Transcriptome data of 80 ESAD and 10 normal tissues were retrieved from the TCGA database. Immune-related differential genes were identified by integrating the ImmPort database. Cox regression analysis was applied to evaluate the prognostic significance of VIPR2. GSVA and ssGSEA were employed to assess the association between VIPR2 and immune-cell infiltration. Functional enrichment was performed using GO, KEGG, and GSEA. Results VIPR2 expression was significantly downregulated in ESAD tissues (P<0.05). High VIPR2 expression was associated with prolonged overall survival (HR=0.246, P=0.047), serving as an independent prognostic factor. Fifteen immune-cell types, including CD8⁺ T cells, NK cells, and dendritic cells, showed significantly higher infiltration in the VIPR2-high group, whereas Th17-cell abundance was decreased (P<0.05). Enrichment analyses revealed that VIPR2 participated in multiple tumor-immune pathways and was positively correlated with PD-1 and CTLA-4 expression (P<0.01). Conclusion VIPR2 may serve as a potential biomarker in the prognostic assessment and could modulate the tumor-immune microenvironment in ESAD.

This paper summarizes professor TU Jinwen's clinical experience in treating cancer-related insomnia （CRI） based on different qi and fire. It is believed that the pathogenesis of CRI can be divided into three stages. At the initial stage， qi movement is constrained， while the strong fire begins to stir， and the sovereign fire is unsettled， when qi is abundant， but the fire is not excessive. For this， Sanhua Jieyu Anshen Decoction （三花解郁安神汤） is suggested， which can move qi and vent constraint， clear and diffuse strong fire， calm the heart and spirit. At the progressive stage， strong fire becomes intense and burning， and qi transformation weakens， with toxin fire harassing the spirit. This is the stage where both qi and fire are excessive， for which Huanglian Jiedu Anshen Decoction （黄连解毒安神汤） can be used to clear and dissipate strong fire， drain fire and resolve toxin， clear heart and calm spirit. At the terminal stage， strong fire subsides， and consumption of qi damages healthy qi， with failure of nourishment of heart spirit， when both qi and fire deplete. Correspondingly， Erren Yangxin Anshen Decoction （二仁养心安神汤） is used to boost qi and nourish yin， restore interaction between the heart and the kidney， nourish the heart and calm spirit.

This article provides a systematic review of the research progress in the mechanisms related to lung cancer and ferroptosis， ferroptosis-related lung cancer biomarkers and gene mutation targets， and ferroptosis-targeted regulation of Chinese medicine in treating lung cancer in the past five years， providing a feasible and effective basis for the prevention and treatment of lung cancer with Chinese medicine and the development of new drugs. According to the available studies， ferroptosis is widely suppressed in lung cancer， while the specific regulatory mechanisms have not been fully elucidated. The suppression is related to lipid metabolism， iron metabolism， cystine/glutamate antiporter system Xc^- （System Xc^-）/glutathione （GSH）/glutathione peroxidase 4 （GPX4）， ferroptosis suppressor protein 1 （FSP1）/coenzyme Q10 （CoQ10）/nicotinamide adenine dinucleotide phosphate ［NAD（P）H］， long non-coding RNA （lncRNA）， nuclear factor E₂-related factor 2 （Nrf2）， and p53. In modern times， traditional Chinese medicine is widely used in the comprehensive treatment of lung cancer， and it has gradually become a hot research topic due to its obvious advantages of anti-tumor activity， high efficacy， and low toxicity. Traditional Chinese medicine plays an important role in the treatment of lung cancer. Studies have shown that the active components， extracts， and prescriptions of Chinese medicine can induce ferroptosis in lung cancer cells through targeted regulation of iron metabolism， lipid metabolism， and p53， Nrf2， LncRNA， and GPX4 pathways to inhibit the growth and proliferation of lung cancer， thus exerting anti-tumor effects. Therefore， regulating ferroptosis is expected to become a new direction for preventing lung cancer. Basic research has shown that Chinese medicine can regulate ferroptosis via multiple targets and pathways in the treatment of lung cancer. At present， Chinese medicine demonstrates great research prospects in regulating ferroptosis to treat lung cancer， which， howeve， still faces challenges to achieve clinical transformation.

Objective:To explore the impact of the stimulator of interferon genes(STING)-interferon regulatory factor 3(IRF3)pathway on the senescence of rapid pacing HL-1 myocytes.Methods:HL-1 cells were divided into five groups: the control group(HL-1 cells without any treatment), pacing group(HL-1 cells paced for 48 hours), STING siRNA group(HL-1 cells paced for 48 hours and transfected with STING siRNA), NC siRNA group(HL-1 cells paced for 48 hours and transfected with NC siRNA), and H151 inhibitor group(HL-1 cells paced for 48 hours with the addition of 1 μmol/L STING inhibitor H151). Mitochondrial membrane potential was assessed in control and pacing group cells, and mitochondrial MitoTracker and TFAM co-localization staining was performed on these cells.Cellular senescence was evaluated using β-galactosidase staining in each group, and the positive rate of cellular senescence was observed and calculated.Western blotting was employed to detect the expression levels of STING, IRF3, P-IRF3, P16, P21, and P53 proteins in all groups.Immunofluorescence was utilized to examine the expression distribution of STING and P21 across the various groups.ELISA was performed to measure the concentrations of interleukin(IL)-1β, IL-6, and IL-8 in the cell supernatants from each group as part of the senescence-associated secretory phenotype(SASP).Results:Compared with the control group, the ratio of mitochondrial JC-1 multimer to monomer was significantly decreased in the pacing group( t=16.42, P<0.05), the co-localization of mitochondrial MitoTracker and TFAM in the cells was significantly weakened, the proportion of cells with positive cellular senescence-associated β-galactosidase staining significantly increased in the pacing group, the expression levels of STING, P-IRF3/IRF3, P16, P21, and P53 proteins were significantly elevated in the pacing group, and the concentrations of IL-1β, IL-6, and IL-8 in the cell supernatants were markedly increased.Compared with the pacing group, the proportion of cells with positive cellular senescence-associated β-galactosidase staining decreased in the STING siRNA group and H151 inhibitor group ( F= 18.13, P<0.05), the expression levels of STING, P-IRF3/IRF3, P16, P21, and P53 were reduced in the STING siRNA group and H151 inhibitor group ( F=16.84, 26.56, 74.70, 31.80, 31.23, all P<0.05), and the concentrations of IL-1β, IL-6, and IL-8 in the cell supernatants decreased( F=197.80、1 339.00、1 308.00, all P<0.001). Conclusions:Rapid pacing of HL-1 cells can promote mtDNA release into the cytoplasm, activate the STING-IRF3 pathway, accelerate cellular senescence, and enhance the secretion of SASP.Inhibiting the expression of STING can delay the senescence induced by the rapid pacing of HL-1 cells and reduce SASP secretion.

In recent years,with the rapid development of mechanical thrombectomy(MT)for acute large vessel occlusion,an increasing number of clinical studies begin to focus on the acute distal medium vessel occlusion(DMVO).This article systematically reviews the existing literature,summarizes the definition and classification of DMVO,the advance in MT,the imaging evaluation methods,and the clinical application of emerging technologies.Currently,the definition of DMVO is mostly based on vascular anatomical features and clinical functional deficits,the etiology of DMVO can be classified as primary and secondary.Due to the small diameter and tortuous running course of distal medium vessels,individualized treatment strategies are often required for patients with DMVO.This review focuses on the efficacy and safety of the therapeutic techniques,including direct thrombectomy,aspiration thrombectomy,stent retriever thrombectomy,and bridging therapy,in treating DMVO,besides,this review also discusses the role of imaging methods,including non-enhanced CT(NCCT),CT perfusion(CTP),CT angiography(CTA),and MRI in the patient screening and treatment decision-making.Meanwhile,the emergence of novel small-scale thrombectomy devices and techniques offers new possibilities for improving recanalization rates and reducing complication risks.Overall,although preliminary studies suggest that MT has promising clinical benefits for the treatment of DMVO,the available evidence remains limited.High-quality randomized controlled trials are urgently needed to further formulate the optimal treatment strategies and promote the precision interventional therapy.

Objective:To investigate the relationship between oxygen consumption (VO 2), carbon dioxide production (VCO 2), and Oxygen Consumption/lactate (VO 2/Lac) with risk of death in patients with severe ARDS. Methods:A retrospective cohort study method was used, and the study subjects were hospitalized for >5 days adult patients with severe ARDS in the central intensive care unit of Henan Provincial People's Hospital from 1 March 2020 to 30 June 2023. The following patients were excluded: IC test was not completed on the 4th day of ICU admission, IC test results were unreliable, mechanical ventilation duration had exceeded 48 h at the time of ICU transfer or admission, palliative care patients and pregnant and parturient women. Using indirect calorimetry to determine VO 2 and VCO 2 values on the 4th day of admission, reviewing medical records to obtain general condition, disease information, blood gas analysis (including lactate value), diagnostic and therapeutic measures, and following up deaths by telephone and time of death. The primary outcome measure was death at 90 days, and the secondary outcome measure was death at 28 days, length of stay in ICU, total length of stay, and total hospitalization cost. Cox regression analysis and linear regression analysis were used to investigate the relationship between VO 2, VCO 2, VO 2/Lac and primary and secondary outcome indexes. Results:A total of 216 patients were enrolled, 78 patients (36.1%) died and 138 patients (63.9%) survived at 90 days. After correction for confounders, the results of multifactorial Cox regression analysis suggested that compared with the Q4 group, HR (95% CI) for 90-day risk of death in the VO 2 Q1 and Q2 groups was 3.21 (1.38, 7.49) and 3.24 (1.42, 7.38), and HR (95% CI) for 90-day risk of death in the VCO 2 Q1, Q2 and Q3 groups was 5.88 (2.33, 14.84), 4.26 (1. 60, 11.34) and 3.54 (1.34, 9.35), respectively, and the HR (95% CI) for 90-day risk of death in the VO 2/Lac Q1, Q2 and Q3 groups were 8.72 (3.01, 25.25), 8.43 (2.91, 24.47) and 4.04 (1.34, 12.17) respectively. P-trends were all <0.05, indicating that VO 2, VCO 2 and VO 2/Lac were linearly and negatively associated with the risk of 90-day mortality. In addition, VO 2, VCO 2, and VO 2/Lac were negatively associated with 28-day risk of death and higher VO 2/Lac was negatively associated with length of ICU stay. Conclusions:VO 2, VCO 2 and VO 2/Lac were negatively associated with 90-day mortality risk and 28-day mortality risk in patients with severe ARDS and may be independent risk factors predicting mortality risk of such patients.

Objective To clarify the effect of unilateral activation of the dopamine type I receptor medium-sized multi-spiny neurons(D1-MSN)in the dorsal striatum of mice on speed.Methods The transgenic animals were combined with optogenetic experiments to specifically activate the D1-MSN in the dorsal striatum of mice at different frequencies and to analyze the rotational behavior and speed of mice when stimulating the D1-MSN.Results Unilateral activation of D1-MSN induces contralateral rotational behavior in mice and either increases or decreases speed.The mechanisms by which different frequencies affect the speed of mice differently.As the frequency of stimulus increased,the contralateral rotational behavior of the mice increased.Unilateral stimulus of D1-MSN increased speed and induced contralateral rotational behavior,and the rotational behavior increased with increasing stimulus frequency.In the experiment where D1-MSN stimulus did not induce rotational behavior,it was found that 5 Hz stimulus still induced an increase in speed,but 15 Hz and 25 Hz stimulus did not induce an increase in speed.Further analysis of the pre-stimulus locomotor state of the mice showed that 5 Hz,15 Hz and 25 Hz stimulus increased speed when the average speed before stimulus was less than 5 cm/s.However,15 Hz stimulus decreased the speed when the average speed before stimulus was greater than 5 cm/s.Conclusion Unilateral activation of D1-MSN in the dorsal striatum modulates speed and induces contralateral rotational behavior in mice,and is related to the frequency of stimulus and the locomotor state of the mice before stimulus.

Objective To evaluate the efficacy,safety and economy of vonoprazan in the treatment of post-endoscopic submucosal dissection(ESD)ulcer by rapid health technology assessment method,and to provide reference for clinical treatment decision.Methods PubMed,Cochrane Library,Embase,ScienceDirect,CNKI,WanFang Data databases and the official website of health technology assessment(HTA)agency were electronically searched to collect HTA reports,systematic reviews/Meta-analysis and pharmacoeconomic studies of vonoprazan in the treatment of post-ESD ulcer from inception to July 31,2024.Two researchers independently screened literature,extracted data,and comprehensively analyzed the results of the included literature on the basis of literature quality evaluation.Results A total of 8 studies were included,all were systematic reviews/Meta-analysis.In terms of effectiveness,compared with proton pump inhibitors(PPI),vonoprazan significantly increased the overall ulcer healing rate after ESD and more rapid reduction of ulcer area(P<0.05).The results of subgroup analysis showed that there was no significant difference in ulcer healing rate between vonoprazan and PPI treatment at 4 or 8 weeks after ESD(P>0.05).Vonoprazan significantly increased the rate of postoperative ulcer reduction in H.pylori positive patients compared with PPI(P<0.05).In terms of safety,compared with PPI,vonoprazan reduced the incidence of overall adverse events rate(P<0.05).The difference in the incidence of delayed bleeding and ulcer perforation between vonoprazan and PPIs showed no statistically significant difference.(P>0.05).Conclusion Vonoprazan demonstrated favorable efficacy and safety in the treatment of ESD ulcers,and further economic studies are warranted.
