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.

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.

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.

ObjectiveTo investigate whether menaquinone-4 （MK-4） can exert a protective effect against carbon tetrachloride （CCl₄）-induced acute liver injury （ALI） in mice by alleviating ferroptosis. MethodsAfter adaptive feeding， adult male ICR mice， aged 8 weeks， were divided into Control group， MK-4 group， CCl₄ model group （6-hour， 12-hour， and 24-hour）， and MK-4+CCl₄ group （6-hour， 12-hour， and 24-hour）， with 6 mice in each group. The mice in the Control group were given intraperitoneal injection of an equal dose of corn oil； the mice in the MK-4 group were given intraperitoneal injection of 40 mg/kg MK-4 solution， followed by an equal dose of corn oil after 1 hour； the mice in the MK-4+CCl₄ group （6-hour， 12-hour， and 24-hour） were given intraperitoneal injection of 40 mg/kg MK-4 solution， and after 1 hour， the mice in this group and the CCl₄ model group （6-hour， 12-hour， and 24-hour） were given intraperitoneal injection of 0.3 mL/kg CCl₄ solution， with samples collected at 6， 12， and 24 hours. HE staining was used to observe the pathological changes of mouse liver； Prussian blue staining was used to observe iron accumulation in liver tissue； a biochemical analyzer was used to measure the serum levels of aspartate aminotransferase （AST） and alanine aminotransferase （ALT）； related kits were used to measure the levels of tissue iron content and the oxidative stress indices malondialdehyde （MDA） and glutathione （GSH） in liver homogenate； RT-PCR was used to measure the expression levels of ferroptosis marker genes （acyl-CoA synthetase long-chain family member 4 ［ACSL4］， prostaglandin-endoperoxide synthase 2 ［PTGS2］， and glutathione peroxidase 4 ［GPX4］） and iron metabolism-related genes （hemojuvelin ［HJV］， transferrin receptor 1 ［TFR1］， and ferroportin ［FPN］）， and Western blot was used to measure the protein expression level of GPX4. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsIn the aging study， compared with the Control group， the CCl₄ model group （6-hour， 12-hour， and 24-hour） had significant increases in liver weight coefficient and the serum levels of ALT and AST （all P<0.05）， and HE staining also showed that liver injury gradually aggravated over time. Meanwhile， compared with the CCl₄ model group （6-hour， 12-hour， and 24-hour）， the MK-4+CCl₄ （12-hour） group had significant reductions in liver weight coefficient and the serum levels of ALT and AST （all P<0.05）， with a reduction in the necrotic area of liver tissue， and therefore， 12-hour mouse tissue samples were used for detection in the following study. Compared with the Control group， the CCl₄ group had a significant increase in MDA and a significant reduction in GSH （both P<0.05）， and compared with the CCl₄ group， the MK-4+CCl₄ group had a significant reduction in MDA and a significant increase in GSH （both P<0.05）. Compared with the Control group， the CCl₄ group had significant increases in the key ferroptosis indices ASCL4 and PTGS2 and a significant reduction in GPX4 （all P<0.05）； compared with the CCl₄ group， the MK-4+CCl₄ group had significant reductions in the mRNA expression levels of ASCL4 and PTGS2 and a significant increase in the mRNA expression level of GPX4 （all P<0.05）. Western blotting showed that compared with the Control group， the CCl₄ group had a significant reduction in the protein expression level of GPX4 （P<0.05）， and compared with the CCl₄ group， the MK-4+CCl₄ group had a significant increase in the protein expression level of GPX4 （P<0.05）. Prussian blue staining showed that compared with the Control group， the CCl₄ group had a significant increase in iron accumulation； after MK-4 intervention， compared with the CCl₄ group， the MK-4+CCl₄ group had a significant reduction in iron accumulation. As for the measurement of iron metabolism genes in mouse liver， compared with the Control group， the CCl₄ group had a significant increase in iron content， significant reductions in the mRNA expression levels of FPN and HJV， and a significant increase in the mRNA expression level of TFR1 （all P<0.05）； after protection with MK-4， there was a significant reduction in iron content， significant increases in the mRNA expression levels of FPN and HJV， and a significant reduction in the mRNA expression level of TFR1 （all P<0.05）. ConclusionMK-4 intervention in advance can alleviate CCl₄-induced ALI in mice， possibly by inhibiting ferroptosis and improving the expression of iron metabolism-related genes in mouse liver.

Objective To investigate the correlation between the expression of long non-coding ribonucleic acid growth arrest specific 5(lncRNA GAS5),phospholysine phosphohistidine inorganic pyrophosphate phos-phatase(LHPP)and epithelial-mesenchymal transition(EMT)in cancer tissues of patients with non-small cell lung cancer(NSCLC)and its clinical significance.Methods Cancer tissues and adjacent tissues of 90 patients with NSCLC who underwent surgical resection in the First Hospital Affiliated to Hebei North College from June 2018 to January 2020 were collected.The expressions of lncRNA GAS5,LHPP and EMT-associated pro-teins[E-calmodulin(E-Cad),N-calmodulin(N-Cad),and vimentin(VIM)]were detected by real-time fluores-cence quantitative polymerase chain reaction.The relationship between lncRNA GAS5 and LHPP mRNA and clinicopathological features in cancer tissues of NSCLC patients was analyzed,and the correlation between ln-cRNA GAS5 and LHPP mRNA and EMT-associated proteins expression in cancer tissues of NSCLC patients was analyzed by Pearson correlation.Kaplan-Meier method was used to plot the survival curves of NSCLC pa-tients with different lncRNA GAS5 and LHPP mRNA expressions,and multivariate Cox regression was used to analyze the prognostic factors of NSCLC patients.Results The expressions of lncRNA GAS5,LHPP mR-NA and E-Cad mRNA in cancer tissues of NSCLC patients were lower than those in adjacent tissues,while the expressions of N-Cad mRNA and VIM mRNA were higher than those in adjacent tissues,with statistical sig-nificance(P＜0.05).Pearson correlation analysis showed that lncRNA GAS5 in cancer tissues of NSCLC pa-tients was positively correlated with E-Cad mRNA expression(r=0.724,P＜0.001),and negatively correla-ted with N-Cad mRNA and VIM mRNA expression(r=-0.699,-0.689).P＜0.001);lncRNA GAS5 was positively correlated with LHPP mRNA expression(r=0.651,P＜0.001).The mRNA expressions of ln-cRNA GAS5 and LHPP in cancer tissues of NSCLC patients with different degrees of differentiation,tumor TNM stage and lymph node metastasis were significantly different(P＜0.05).Kaplan-Meier survival curve a-nalysis showed that the 3-year overall survival rate in the lncRNA GAS5 high expression group[68.18％(30/44)]was higher than that in the lncRNA GAS5 low expression group[36.96％(17/46)].The 3-year overall survival rate in the high LHPP mRNA expression group[67.39％(31/46)]was higher than that in the lowLHPP mRNA expression group[36.36％(16/44)],and the difference was statistically significant(x2=10.274,10.322,P＜0.05).Low differentiation,TNM stage Ⅲ and lymph node metastasis were independent risk factors for death in NSCLC patients,and lncRNA GAS5≥1.32 and LHPP mRNA≥1.12 were independ-ent protective factors(P＜0.05).Conclusion The low expression of lncRNA GAS5 and LHPP mRNA in cancer tissues of patients with NSCLC is related to EMT-associated proteins expression,differentiation de-gree,tumor TNM stage,lymph node metastasis and prognosis,and may become a new target for the diagnosis and treatment of NSCLC.

Objective To investigate the mechanism of bis(2-ethylhexyl)phthalate(DEHP)in inducing cholestasis and liver injury in mice.Methods In the in vivo experiment,adult female ICR mice were randomly divided into control group(corn oil)and DEHP group(200 mg/kg/d),and a model of cholestasis was established by intragastric administration for 4 weeks.After blood and liver tissue samples were collected from all mice,a biochemical analyzer was used to measure the level of total bile acid(TBA)in serum and the liver,and a microplate reader was used to measure alkaline phosphatase(ALP)and gamma-glutamyl transpeptidase(GGT);HE staining was used to observe the pathological changes of the liver;RT-PCR was used to measure the mRNA expression levels of the inflammatory factors interleukin-1β(IL-1β),interleukin-6(IL-6),and tumor necrosis factor-α(TNF-α)in the liver;liquid chromatography/triple quadrupole mass spectrometry was used to measure the bile acid profile in the liver of mice.In the in vitro experiment,AML-12 mouse hepatocytes were cultured and treated with DEHP(250 μmol/L),DCA(125 μmol/L),and CDCA(125 μmol/L)for 24 hours,and RT-PCR was used to measure the mRNA expression levels of the inflammatory cytokines IL-1β,IL-6,and TNF-α.The independent-samples t test was used for comparison of continuous data between two groups;a one-way analysis of variance was used for comparison between multiple groups,and the LSD-t test was used for further comparison between two groups.Results The in vivo experiment showed that compared with the control group,the DEHP group had significant increases in the serum levels of TBA,ALP,and GGT and the level of TBA in the liver(the t values are respectively-4.396,-5.109,-8.504,-3.792 and-7.974,all P<0.05,).Compared with the control group,the DEHP group had significant increases in cholic acid,chenodeoxycholic acid,taurocholic acid,deoxycholic acid,and ursodeoxycholic acid(the t values are respectively-2.802,-3.177,-2.633,-2.874 and-2.311,all P<0.05).HE staining of the liver showed that the mice in the DEHP group had enlargement of the portal area,bile duct deformation,inflammatory cell infiltration around the bile duct,and significant increases in the mRNA expression levels of the inflammatory factors IL-1β,IL-6,and TNF-α in the liver(the t values are respectively-2.539,-2.823 and-4.636,all P<0.05).The in vitro experiment showed that the actual difference in hepatocyte viability after 0-1 000 μmol/L DEHP treatment does not exceed 15%,but there were significant increases in the mRNA expression levels of the inflammatory cytokines IL-1β,IL-6,and TNF-α after treatment with DEHP at different concentrations of 125 μmol/L,250 μmol/L,and 500 μmol/L(all P<0.05).Compared with DEHP stimulation alone,the combined stimulation of CDCA and DEHP upregulates the cytokine in hepatocyte IL-1β mRNA levels(P<0.01);the combined stimulation of DCA and DEHP can significantly increase the cytokine in hepatocyte IL-1β and IL-6 mRNA levels(all P<0.01).Conclusion DEHP exposure can cause cholestasis and induce liver inflammation in mice,possibly by promoting the production of toxic bile acids and the secretion of inflammatory factors.
