Objective This study reports on the obligatory parasitism of water mites Arrenurus sp. on Anopheles messeae at the Manzhouli Port, Inner Mongolia, China. Methods Duing July 2024, a survey on the mosquito diversity was conducted at the Manzhouli Port. Captured mosquitoes and their ectoparasites were identified to species level. Results A total of 1840 adult mosquitoes were collected, representing species from three genera: Culex(Cx. modestus, Cx. pipiens pallens), Aedes(Ae. dorsalis, Ae. flavidorsalis, Ae. flavescens), and Anopheles (An. messeae). Among all the mosqutioes specimens,3 out of 150 captured An. messeae were found to carry ectoparasitic mites, with number of 2,4,27 mites separately. Morphological and molecular identification reached the same result as water mites(Hydrachnidiae, Hydracrina). COI gene sequence showed 94% similarity with the closest species Arrenurus truncatellus. Conlusions Literature review suggests water mites are host-specific parasitism of mosquito species and herein with the first record of Arrenurus sp. parasiting on An. Messeae in the most high-latitude region globally.

Objective:To investigate the effect of family primary caregiver-centered enabling education on mental resilience and self-efficacy in patients with acute myocardial infarction(AMI)after percutaneous coronary inter-vention(PCI).Methods:This randomized controlled study enrolled 94 AMI patients undergoing PCI in First Affili-ated Hospital of Xinjiang Medical University between July 2022 and December 2022.They were divided into control group(n=47,traditional nursing)and intervention group(n=47,family primary caregiver-centered enabling ed-ucation).Both groups were intervened for 3 months.Cardiac function,mental resilience,self-efficacy,social support,sleep quality,quality of life and incidence of adverse events were compared between the two groups.Re-sults:After intervention,compared with patients in control group,those in intervention group had significant high-er left ventricular ejection fraction(L VEF)[(59.20±5.93)％vs.(52.57±4.67)％],scores of Connor-Davidson Resilience Scale(CD-RISC)[(91.96±1.61)points vs.(80.02±2.63)points],General Self-Efficacy Scale(GSES)[(32.53±3.21)points vs.(21.45±2.09)points],Social Support Rating Scale(SSRS)[(49.27±3.11)points vs.(39.45±2.72)points],and significant lower left ventricular end-diastolic diameter(LVEDd)[(50.54±3.57)mm vs.(59.03±3.62)mm],left ventricular end-systolic diameter(LVESd)[(39.60±2.31)mm vs.(45.52±2.68)mm],scores of Athens Insomnia Scale(AIS)[(9.63±1.68)points vs.(12.90±1.20)points],Myocardial Infarction Dimensional Assessment Scale(MIDAS)[(89.24±2.63)points vs.(117.63±4.89)points]and incidence of adverse events(4.26％vs.21.28％)(P＜0.05 or＜0.01).Conclusion:Family primary caregiver-centered enabling education could improve the cardiac function and mental resilience,enhance self-efficacy and social support,improve sleep quality and quality of life,and reduce the incidence of adverse events in AMI patients after PCI.

Objective:To investigate the cffect of Orem's self-care theory on mental health and cognitive function in patients with chronic heart failure(CHF).Methods:We retrospectively collected clinical data of 97 CHF patients treated in the First Affiliated Hospital of Xinjiang Medical University between February 2019 and August 2022.According to intervention way,they were divided into control group(n=45,routine intervention)and intervention group(n=52,Orem's self-care theory model intervention).Both groups were intervened for 6 months.Scores of Hamil-ton Anxiety scale(HAMA),Hamilton Depression scale(HAMD),Mini-Mental State Examination(MMSE),left ven-tricular ejection fraction(LVEF),resting heart rate(HR),scores of the Medical Outcomes Study 36-Item Short-Form Health Survey(SF-36)and Barthel index were compared between two groups.Kaplan-Meier survival curve was used to compare incidence of unfavorable outcome between two groups.Results:After 6-month intervention,compared with pa-tients in control group,those in intervention group had significant lower scores of HAMA[(12.50±4.89)points vs.(19.09±5.80)points],HAMD[(12.31±4.28)points vs.(19.56±5.79)points]and HR[(87.33±7.42)beats/min vs.(100.11±7.89)beats/min],and significant higher LVEF[(50.25±5.24)％vs.(42.11±4.51)％],scores of MMSE[(21.90±3.37)points vs.(18.27±3.50)points],SF-36[(63.65±10.43)points vs.(51.71±6.83)points]and Barthel index[(60.67±8.43)points vs.(45.00±9.56)points](P＜0.001 all).Kaplan-Meier survival analysis indicated that incidence of unfavorable outcome in intervention group was significantly lower than that of control group(5.77％vs.24.44％,P=0.035).Conclusion:Orem's self-care theory intervention could significantly improve negative emotions and cognitive ability,restore patients'cardiac function,improve the quality of life and self-care capacity,and re-duce risk of unfavorable outcome in CHF patients.

Objective:To explore mechanism of Caspase-11/GSDMD non-classical cell pyroptosis pathway in inflammatory response of RAW264.7 monocyte macrophages induced by ricin toxin.Methods:Cell pyroptosis model induced by LPS+Nigericin was used as a positive control,and cells were induced with 40 ng/ml and 80 ng/ml of ricin toxin for 8 hours.Cell release of lactate dehydro-genase(LDH)was measured by LDH cell release assay;cell viability was assessed by flow cytometry(Annexin Ⅴ/PI double staining);gene expressions of Caspase-11,GSDMD,IL-1β and IL-18 were measured by RT-qPCR;protein levels of Caspase-11 and GSDMD were measured by Western blot;secretion levels of inflammatory cytokines IL-1β and IL-18 in cell supernatant were measured by ELISA.Results:Compared with normal control group,RAW264.7 cells treated with ricin toxin showed swelling,cell membrane rupture,significantly increased LDH release(P<0.001),significantly increased pyroptosis rate(P<0.001),significantly increased expression of pyroptosis-related genes Caspase-11,GSDMD,IL-1β and IL-18(P<0.05),significantly increased protein expressions of Caspase-11 and GSDMD(P<0.05),and significantly increased secretion levels of IL-1β and IL-18 in cell supernatant(P<0.05).Results of ricin toxin treatment group were consistent with LPS+Nigericin cell pyroptosis positive control group.Conclu-sion:Ricin toxin may induce cell pyroptosis in RAW264.7 cells through Caspase-11/GSDMD non-classical pathway,thereby promoting inflammatory response.

Objective:To investigate the prevalence of chronic endometritis(CE)in patients with repeated implantation failure(RIF),and the correlation between diagnostic indexes of CE and classification of peripheral blood immune cells.Methods:A total of 64 patients with RIF who visited Outpatient of Hebei Reproductive Health Hospital from January 2020 to December 2021 were retrospec-tively analyzed.General information of patients,results of hysteroscopy and endometrial immunohistochemistry in the mid luteal phase,the number and percentage of NK cells,Th1 cells,Th2 cells,Th17 cells and Treg cells in peripheral blood,and Th1/Th2,Th17/Treg were collected,and the pregnancy outcome of retransplantation was followed up.To evaluate the consistency of hysteroscopy and endometrial immunohistochemistry CD138 in diagnosis of CE in RIF patients,to analyze whether chronic inflammation of endome-trium was related to classification of peripheral blood immune cells,and to analyze the pregnancy outcome of patients with RIF diag-nosed with CE after retransplantation.Results:Prevalence of CE in RIF patients detected by hysteroscopy was 53.12%,which was sig-nificantly higher than that detected by endometrial immunohistochemistry CD138(25.00%,P<0.05).There was no significant differ-ence in the number and percentage of immune cells in peripheral blood between CE and non CE patients.After antibiotic treatment,the 12-week continuous pregnancy rate and live birth rate in the CD138 positive group were higher than those in negative group,with a statistically significant difference(P<0.05).Conclusion:The combination of hysteroscopy and endometrial CD138 immunohistochem-istry at the right time for RIF patients is beneficial to improve their pregnancy rate and pregnancy outcome.The infiltration of endome-trial plasma cells does not affect the classification of peripheral blood immune cells.

Aim To perform high-throughput screen-ing of immunomodulatory traditional Chinese medicine(TCMs)based on an in vitro B cell differentiation-antibody secretion model,identifying active herbal candidates with immune-enhancing properties to pro-vide novel therapeutic options and theoretical support for influenza virus treatment in immunocompromised in-dividuals.Methods B cells were stimulated with dif-ferent concentrations of cytosine-phosphate-guanine oli-godeoxynucleotide 2006(CpG)and nterleukin-2(IL-2)to promote proliferation,differentiation,and anti-body secretion,and the effects of varying concentra-tions of the solvent DMSO were also evaluated.The op-timal conditions for the B cell differentiation-anti-body secretion model were determined based on the se-cretion levels of three antibody isotypes.The feasibility of the model was further validated using rapamycin,a known B cell function inhibitor.On this basis,a high-throughput screening platform for immunomodulatory a-gents was optimized and established.Subsequently,the immune-enhancing activity of 465 polarity extract from TCMs was evaluated.Results The optimal con-ditions for the model were determined as 2 mg·L-1 CpG,1.67 × 106 nkat·L-1 IL-2,and DMSO with a volume fraction of 0.1％.Rapamycin effectively inhib-ited B cell differentiation into plasmablast and signifi-cantly reduced antibody production,indicating the reli-ability of the model.Multiple rounds of screening re-vealed that the dichloromethane extract of licorice,the dichloromethane extract of Vinegar-processed Curcumae Rhizoma,the cyclohexane extract of Honey-prepared Radix Asteris,and the aqueous extract of Siphonostegia chinensis Benth were identified to significantly promote both B cell proliferation and differentiation and anti-body secretion at a concentration of 600 μg·L-1.Conclusion This study successfully optimizes an in vitro B cell differentiation-antibody secretion model and identifies several TCM extracts,including licorice,with potential immune-enhancing activity.

A mounting body of research suggests that circRNAs significantly contribute to the develop-ment of myocardial fibrosis.The microarray results of human circular RNA expression profile indicated that circHERC4_041 expression increased in the myocardium of patients with heart failure,RT-qPCR a-nalysis confirmed that the myocardial expression level of circHERC4_041 in individuals with heart failure were considerably elevated compared to that in healthy organ donors.Fluorescence in situ hybridization(FISH)confirmed that circHERC4_041 was abundant in the cytoplasm of human cardiomyocyte AC16.Overexpression of circHERC4_041 in mouse myocardial fibroblasts(mCFs)mediated by adenovirus in-hibited the expression of fibrosis-related proteins in mCFs.Experiments involving cell proliferation,wound healing,and Transwell assays demonstrated that overexpression of circHERC4_041 suppressed the growth and mobility of mCFs(P＜0.001).Sequence analysis results suggested that circHERC4_041 con-tains potential ribosome entry sequence(IRES)and open reading frame(ORF).Western blot confirmed that circHERC4_041 could translate the 516 amino acid HERC4-516aa protein,which was mainly located in the cytoplasm of the cell.Cell functional experiments confirmed that circHERC4_041 inhibited the fi-brotic phenotype of mCFs by specifically translating HERC4-516aa(P＜0.05).The specific interaction between HERC4-516aa and transglutaminase 2(TGM2)was confirmed by IP-MS screening and Co-IP i-dentification.Further results found that the degradation of TGM2 was promoted through proteasome path-way.The overexpression of TGM2 in mCFs facilitated by adenoviral vectors could counteract the suppres-sive effects of HERC4-516aa on the fibrotic phenotype of mCFs.Therefore,this study confirmed that the HERC4-516aa protein translated by circHERC4_041 can specifically bind to TGM2 to inhibit the fibrotic phenotype of myocardial fibroblasts.

Objective To construct machine learning models to predict the incidence of linezolid-induced thrombocytopenia(LIT).Methods A total of 198 patients treated with linezolid in a hospital between January 2020 and March 2024 were retrospectively included.Firstly,the patients were divided into LIT and non-LIT groups,and the basic characteristics of the two groups were compared.Then,the variables with significant differences between the two groups were selected as potential risk factors to construct models for predicting LIT,including Logistic regression,decision tree and random forest models,and the prediction performance of the models was evaluated and compared.Results There were 52(26.3％)patients developed LIT during the treatment.The univariate analysis showed significant differences in linezolid trough concentration(Cmin),baseline platelet counts and creatinine clearance,the incidence of cerebrovascular disease,acute respiratory distress syndrome,and abdominal infection in patients with and without LIT.Among the three models built based on these variables,the random forest model has the best predictive performance.The results of variable importance analysis based on random forest model showed that Cmin,baseline platelet count and combined with acute respiratory distress syndrome had higher importance scores.Conclusions The random forest model has high accuracy in predicting the occurrence of LIT,and the risk of LIT is higher in patients with higher levels of linezolid exposure and lower baseline platelets.

Aim To study the role and mechanism of ML210 in glioma.Methods The cell viability was detected by CCK8 assay.The percentage of dead cells was detected by SYTOXstaining.The role of ferroptosis-signaling pathway in gliomas was detected bygenomics.Cell proliferation was observed by EdU staining and clone formation assay.Cell migration ability was detec-ted by scratch healing assay.The apoptosis was detec-ted by flow cytometry.Cell mitochondrial function was assesses by JC-1 staining.The mechanism of action of ML210 was detected by molecular docking coupled with immunoblotting assay(Western blot).The levels of ROS,MDA were observed by ELISA.Results Compared with the control group,ML210 treatment dose-dependently decreased glioma cell viability,in-hibited cell proliferation,migration,and increased cell apoptosis and mitochondrial dysfunction,which were reversed by ferroptosis antagonists.Gene microarray screening showed that 688 genes of the ferroptosissig-naling pathway were aberrant and 10 signaling path-ways were altered in gliomas.Molecular docking re-sults showed that ML210 binding to GPX4 significantly inhibited the protein expression level of GPX4 and pro-moted the elevation of ROS and MDA levels.Conclu-sions ML210 produces anti-glioma cells via GPX4-mediated ferroptosis pathway.

Alcoholic liver disease(ALD)is a liver disease caused by long-term heavy drinking and one of the most common causes of liver-related morbidity and mortality.According to Chinese medicine,the development of ALD is mainly related to alcoholism,and the evolution of its pathology is a gradually aggravating process.Wine-heat injures the liver,without obvious organic lesions at the initial stage,and as the disease progresses to different stages,internal dampness appears,dampness depresses and transforms into heat,and Qi stagnation and blood stasis are gradually aggravated,which affects the functions of various internal organs,directly or indirectly,and creates a complex mechanism of crosstalk between the liver and other organs,which leads to the pathological condition of This leads to the pathological state of multi-organ dysfunction.Modern research has found that long-term alcohol abuse not only causes direct damage to the liver,but also leads to progression to end-stage liver disease by altering the intestinal barrier function and intestinal microbial community,and producing kidney damage and cardiac function.This article reviewed recent studies on the interactions between the liver and other organs in light of the Chinese and Western pathogenesis of alcoholic liver disease and the theory of organ crosstalk,and introduces potential strategies for the treatment of alcoholic liver disease,which will provide a reference for the discovery of new therapeutic avenues.
