According to statistics from the Extracorporeal Life Support Organization(ELSO),as of October 2023,a total of 198 623 patients worldwide had received extracorporeal membrane oxygenation(EC-MO)support.In recent years,the number of ECMO treatment cases in China has increased rapidly,reaching 10 656 cases in 2022.It was previously believed that fat emulsions could easily lead to ECMO system failures due to their hydrophobic nature,thereby limiting their use during ECMO.However,many clinically used drugs are lipid-soluble,and restricting their use not only increases treatment difficulty for these patients but may e-ven affect their prognosis.With advancements in material technology and membrane lung manufacturing processes,intravenous lipid emulsion(ILE)now exerts significant effects on ECMO systems.This article re-views recent domestic and international research progress regarding the effects of ILE on ECMO systems,ai-ming to provide more evidence-based medical support for ILE application in ECMO patients.

Objective To establish a mouse model of infection with the minimum lethal dose of Vibrio vulnificus(V.vulnificus)and to evaluate the protective efficacy of inactivated whole-cell(IWC)vaccine using this model.Methods A mouse model of lethal-dose infection was established by intraperitoneal injection of different doses of V.vulnificus.Bacterial colonization in the organs was detected with tissue homogenate plating,and pathological changes in the organs were observed after tissue section staining.Flow cytometry was used to detect immune cell responses after liver tissues were digested into single-cell suspension.IWC vaccine of V.vulnificus was prepared,and the mice were immunized through different routes to observe the protective efficacy of the vaccine.Results A mouse model of infection with the minimum lethal dose at 1×106 CFU of V.vulnificus was successfully established.After infection,the bacteria were mainly colonized in the liver of mice and caused severe pathological damages.Compared with the uninfected mice,the proportion of neutrophils in the liver was significantly increased in the infected mice,whereas the proportions of B cells and T cells were correspondingly decreased(P<0.05).A single intramuscular or intraperitoneal injection of the IWC vaccine could protect the mice effectively against lethal infection of V.vulnificus in 7 d later(P<0.01),although the level of serum IgG having no significant increase.Conclusion A mouse model of lethal-dose infection with V.vulnificus is successfully established,with histopathological characteristics.The IWC vaccine of V.vulnificus rapidly mediates immune protection in this model probably independent of IgG.

Objective To explore the traditional Chinese medicine(TCM)syndrome character-istics and medication patterns of cerebral small vessel disease(CSVD)using data mining techniques.Methods Clinical research literature on TCM treatment of CSVD,published from the establishment of the database to September 1,2024,was retrieved from the China National Knowledge Infrastructure(CNKI),Wanfang,and VIP databases.Analyses were conducted on syndromes,drug frequencies,properties,flavors,and meridian tropisms.Data mining was performed using R4.4.1 software to ex-plore associations,correlations,and clustering of TCM herbs,aiming to elucidate medication patterns in CSVD treatment.Results A total of 60 prescription formulas for treating CSVD were screened,involving 142 TCM herbs with a total usage frequency of 1,312 times.The top five most frequently used herbs were Chuanxiong,Danggui,Dilong,Huangqi,and Chishao.Herb properties were pre-dominantly warm and cold;flavors were mainly pungent,bitter,and sweet;and meridian tropisms were primarily to the liver,spleen,and heart meridians.Twenty-nine strong association rules were identified,and association analysis revealed core herbal combinations centered around Chuanxiong,Chishao,and Danggui.Clustering analysis yielded five herbal combinations.Conclusion CSVD is characterized by a deficiency in essence and excess in superficiality.Treatment should focus on tonify-ing deficiencies and eliminating excesses,combining both tonification and purgation methods.Medication patterns predominantly involve herbs for promoting blood circulation and removing blood stasis,often combined with herbs for nourishing the kidney and marrow,calming the liver and suppressing wind,and awakening the mind and opening the orifices.

ObjectiveTo investigate the effect and potential mechanism of Dihuangyin on 2， 4-dinitrochlorobenzene （DNCB） -induced model mice with atopic dermatitis （AD）. MethodA mouse model with AD was established by repeatedly stimulating the back skin of mice with DNCB. After successful modeling， the mice were randomly divided into model group， Runzao group （0.78 g·kg^-1）， and high， medium， and low dose （40.30， 20.15， and 10.08 g·kg^-1） groups of Dihuangyin， with 12 mice in each group， and the blank group consisted of 12 mice， 72 in total. The administration groups were given the corresponding liquid by dose， and the blank group and model group were given the same dose of pure water by intragastric administration， once a day. The skin lesions and scratching times of mice were observed after continuous administration for two weeks. The back skin lesions of mice were stained with hematoxylin-eosin （HE） and toluidine blue to observe the pathology. The contents of serum immunoglobulin E （IgE）， interleukin-4 （IL-4）， interleukin-6 （IL-6）， and interferon-γ （IFN-γ） were detected by enzyme-linked immunosorbent assay （ELISA）. The mRNA expression levels of IFN-γ， IL-4， IL-6， Janus kinase 1 （JAK1）， and transcriptional activator 3 （STAT3） in skin lesion tissue were detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. The expressions of JAK1， phosphorylation（p）-JAK1， STAT3， and p-STAT3 proteins in skin lesion tissue were detected by Western blot. ResultCompared with the blank group， the back skin of the model group showed large-scale scab， dryness， erosion， hypertrophy with scratching， epidermal hyperplasia with hyperkeratosis and parakeratosis， hyperacanthosis with edema， and a large number of mast cell infiltration in the dermis， some of which were degranulated. The contents of IgE， IL-4， IL-6， and IFN-γ in the serum of mice were significantly increased （P<0.01）， and the protein expression levels of p-JAK1， STAT3， and p-STAT3 and mRNA expressions of IL-4， IL-6， IFN-γ， JAK1， and STAT3 in skin lesion tissue were significantly increased （P<0.01）. Compared with the model group， only a small amount of dryness and desquamation were observed in the back skin of mice in each administration group， and cell edema was reduced. The inflammatory infiltration was significantly reduced， and the number of mast cell infiltration was significantly decreased. The serum IgE， IL-4， IL-6， and IFN-γ of mice were decreased to varying degrees （P<0.05， P<0.01）. The protein expression levels of p-JAK1， STAT3， and p-STAT3 and mRNA expressions of IL-4， IL-6， IFN-γ， JAK1， and STAT3 in skin lesion tissue were significantly decreased， and the effect of high dose group of Dihuangyin was the best （P<0.01）. ConclusionDihuangyin can improve skin lesions and pruritus in mice with AD， and its mechanism may be related to the effective regulation of cytokines on the helper T cells （Th1）/Th2 axis by interfering with the JAK1/STAT3 signaling pathway and affecting skin barrier function.

Objective To investigate the correlation and consistency between the parameters of thromboelastography(TEG)and routine coagulation tests,and to evaluate the application value of the two methods in heparin anticoagulation monitoring and coagulation function monitoring in patients receiving extracorporeal membrane oxygenation(ECMO)therapy.Methods A total of 138 patients who recieved ECMO in the Department of Critical Care Medicine of the People's Hospital of Guangxi Zhuang Autonomous Region from October 2021 to December 2022 were selected.A total of 317 pairs of ordinary TEG and heparinase-modified TEG(hmTEG)parameters measured simultaneously were analyzed for correlation and consis-tency with activated partial thromboplastin time(APTT),fibrinogen(Fib),and platelet count(Plt),and the parameters tested when ECMO was established and 24 hours after ECMO operation were compared.Results The correlation coefficient between R values and APTT of hmTEG(r=0.441,P<0.05)was lower than that of ordinary TEG(r=0.547,P<0.05).The parameters α-Angle and K value of ordinary TEG were not correlated with Fib(P>0.05),while as for hmTEG,the correla-tion was 0.359(P<0.05)and-0.343(P<0.05),respectively.The correlation between MA value of hmTEG and Plt was 0.456(P<0.05),which was much lower than its correlation with Fib(r=0.715,P<0.05).APTT and hmTEG had moderate agreement in judging the anticoagulant effect of UFH(P<0.05).Plt at 24 hours after ECMO was significantly lower than that at establishment of ECMO(P<0.05).Fib,APTT and hmTEG parameters were not significantly different between the two groups(P>0.05).Conclusion The parameters of hmTEG can better reflect the real level of coagulation factors in patients receiving ECMO.The results of hmTEG and APTT are complementary to assess whether heparin in ECMO patients is over-dosed,and hmTEG has unique advantages.Routine coagulation tests and TEG cannot replace each other,and the combina-tion of them can achieve better anticoagulation and coagulation management.

Objective:To examine the impact of sleep quality on cognitive function in older adults with mild cognitive impairment(MCI)and explore the potential mediating role of depression.Methods:Using a cross-sectional design, we conducted an on-site questionnaire survey among 310 elderly individuals with MCI in Haishu District, Ningbo City from April to June 2021.Out of the 310 questionnaires collected, 299 were deemed valid.The survey encompassed gathering basic demographic information of the participants, as well as administering the Montreal Cognitive Assessment Scale, Patient Health Questionnaire Depression Scale, and Pittsburgh Sleep Quality Index Scale.Results:The cognitive functions of patients with MCI were found to be positively related to their education level( F=3.89, P<0.05).The correlation analysis indicated that sleep quality was positively correlated with depression( r=0.40, P<0.01)and negatively correlated with cognitive function( r=-0.22, P<0.01).Furthermore, a significant negative correlation was observed between depression and cognitive function( r=-0.20, P<0.01).The mediation analysis revealed that depression played a role in mediating the influence of sleep quality on cognitive function, with a mediation effect of -0.02(95% CI: -0.03--0.01). Conclusions:The cognitive function of elderly individuals with MCI can be significantly affected by sleep quality, with depression playing a mediating role.

Objective To evaluate the stability,safety and immune enhancement and anti-tumor effects of Wilms'tumor gene 1(WT1)peptide combined with AddaVaxTM emulsion vaccine for acute myeloid leukemia.Methods The stability of WT1 peptide in the adjuvant vaccine was evaluated using MALDI-TOF-MS time-of-flight mass spectrometry.Female C57BL/6 mice were randomly divided into PBS group,WT1 peptide group,and WT1 peptide+AddaVaxTMemulsion adjuvant vaccine group.The immunization was performed at a dose of 50 μg/mouse for antigen and 50 μg/mouse for adjuvant,with intramuscular injection on days 0,14,and 28.HE staining was used to assess the toxicity of intramuscular vaccination on mouse organ tissues.Cytokine levels were detected by ELISA,and the number of IFN-γ-secreting splenocytes was measured by ELISpot.Flow cytometry was employed to detect the maturation of bone marrow-derived dendritic cells(BMDCs)promoted by the vaccine in vitro and the promotion for lymphocyte activation,and H-2Db WT1 tetramer was utilized to detect the proportion of specific CD8+T cells.After establishing a mouse leukemia tumor model using the C1498-mWT1 stable cell line,the anti-tumor effects of the vaccine for prevention and treatment were evaluated.Results The WT1 peptide stably existed in the vaccine without causing significant organ tissue changes in mice after intramuscular injection.Compared to the mice immunized with WT1 aqueous solution,the mice after intramuscular injection of the WT1 peptide emulsion adjuvant vaccine showed stronger immune responses of Th1 cells,including IFN-γ and TNF-α,as well as Th17 cells of IL-17A(P＜0.05),and the mice had not only promoted number of IFN-γ secreting splenocytes(P＜0.01)but also enhanced maturation of BMDCs,as indicated by an increase in the proportions of CD40+/CD11c+and CD86+CD80+/CD11c+ cells(P＜0.05).Additionally,there were increases in both the proportion of CD4+/CD3+T and CD69+/CD8+T cells(P＜0.05)and the proportion of specific CD8+T cells(P＜0.05).In the anti-tumor effect study using the C1498-mWT1 mouse model,the median survival time of the WT1+AddaVaxTM group was extended by 6 d compared to the WT1 aqueous solution group.At day 50,the survival rate of mice in the WT1+AddaVaxTM group was still 28.5％,while all mice in the other groups had died(P＜0.05).Conclusion The vaccine with the WT1 peptide and AddaVaxTM emulsion adjuvant exhibits good immunological and anti-tumor effects.

Objective To investigate the antibacterial effect and its preliminary mechanism of lavender essential oil on multi-drug resistant Acinetobacter baumannii.Methods Micro-dilution method was used to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC)of lavender essential oil against multi-drug resistant Acinetobacter baumannii,and bactericidal kinetic study was employed to determine the onset and maintenance time of lavender essential oil.Meanwhile,the promoting and therapeutic effects of lavender essential oil on wound healing were observed in a mouse model of infection.Subsequently,crystal violet staining was used to determine the inhibition and clearance of multi-drug resistant Acinetobacter baumannii biofilm by lavender essential oil,and laser confocal microscopy was utilized to observe the survival of bacteria in biofilms.NanoDrop instrument was utilized to quantify the leakage of bacterial DNA nucleic acid and protein after intervention with 3 and 6 mg/mL lavender essential oil,and the leakage of bacterial potassium ion was measured by potassium ion test kit.Proteomics technology combined with bio-informatics were applied to explore the action mechanism of lavender essential oil against multi-drug resistant Acinetobacter baumannii.Results The MIC and MBC of lavender essential oil were both 6 mg/mL,which could kill almost all multi-drug resistant Acinetobacter baumannii at the time point of 120 min,and showed an obvious dose-and time-dependent manner.The overall animal model evaluation showed that both 3 and 6 mg/mL lavender essential oil could promote wound healing,and the curative effect was obvious.Further studies confirmed that 3 mg/mL lavender essential oil had a certain biofilm inhibitory effect on multi-drug resistant Acinetobacter baumannii,and 6 mg/mL also had a certain biofilm clearance effect under the same conditions.Meanwhile,when incubated at 37℃ for 1 h,the dose of 3 mg/mL could increase the leakage of DNA nucleic acid and protein,and significantly promote the efflux of potassium ions.Proteomic analysis suggested that the antibacterial effect of lavender essential oil may be related to affecting the oxidorereductase activity and cell metabolic process of multi-drug resistant Acinetobacter baumannii,and interfering with the biosynthesis of cell wall/membrane/envelope and other structures.Conclusion Lavender essential oil at 3 mg/mL can play an antibacterial effect against multi-drug resistant Acinetobacter baumannii,and its mechanism may be related to the destruction of bacterial biofilm and interference with bacterial metabolism.

Background/Aims: Roxadustat, an oral medication for treating renal anemia, is a hypoxia-inducible factor prolyl hydroxylase inhibitor used for regulating iron metabolism and promoting erythropoiesis. To investigate the efficacy and safety of roxadustat in patients undergoing peritoneal dialysis (PD) with erythropoietin hyporesponsiveness. Methods: Single-center, retrospective study, 81 PD patients (with erythropoietin hyporesponsiveness) were divided into the roxadustat group (n = 61) and erythropoiesis-stimulating agents (ESAs) group (n = 20). Hemoglobin (Hb), total cholesterol, intact parathyroid hormone (iPTH), brain natriuretic peptide (BNP), related indicators of cardiac function and high-sensitivity C-reactive protein (hs-CRP) were collected. Additionally, adverse events were also recorded. The follow-up period was 16 weeks. Results: The two groups exhibited similar baseline demographic and clinical characteristics. At baseline, the roxadustat group had a mean Hb level of 89.8 ± 18.9 g/L, while the ESAs group had a mean Hb level of 95.2 ± 16.0 g/L. By week 16, the Hb levels had increased to 118 ± 19.8 g/L (p < 0.05) in the roxadustat group and 101 ± 19.3 g/L (p > 0.05) in the ESAs group. The efficacy of roxadustat in improving anemia was not influenced by baseline levels of hs-CRP and iPTH. Cholesterol was decreased in the roxadustat group without statin use. An increase in left ventricular ejection fraction and stabilization of BNP were observed in the roxadustat group. Conclusions For PD patients with erythropoietin hyporesponsiveness, roxadustat can significantly improve renal anemia. The efficacy of roxadustat in improving renal anemia was not affected by baseline levels of hs-CRP0 and iPTH.

Objective To predict the potential suitable habitat of Haemaphysalis concinna in Heilongjiang Province under different climatic scenarios. Methods The geographic locations of ticks in Heilongjiang Province from 1980 to 2022 were captured from literature review and field ticks monitoring data from Harbin Center for Disease Control and Prevention in Heilongjiang Province, and the tick distribution sites with spatial correlations were removed using the software ArcGIS 10.2. The environment data under historical climatic scenarios from 1970 to 2000 and the climatic shared socioeconomic pathways (SSP) 126 scenario model from 2021 to 2040 and from 2041 to 2060 were downloaded from the WorldClim website, and the elevation (1 km, 2010), population (1 km grid population dataset of China, 2010) and annual vegetation index (1 km, 2010) data were downloaded from the Resource and Environmental Science and Data Center, Institute of Geographical Sciences and Natural Resources, Chinese Academy of Sciences. The contribution of environmental factors to H. concinna distribution was evaluated and environmental variables were screened using the software MaxEnt 3.4.1 and R package 4.1.0, and the areas of suitable habitats of H. concinna and changes in center of gravity were analyzed using the maximum entropy model in Heilongjiang Province under different climatic scenarios. In addition, the accuracy of the maximum entropy model for prediction of H. concinna distribution was assessed using the area under curve (AUC) of the receiver operating characteristic curve. Results A total of 79 H. concinna distribution sites and 24 environmental variables were collected, and 70 H. concinna distribution sites and 9 environmental factors that contributed to distribution of the potential suitable habitats of H. concinna in Heilongjiang Province were screened. The three most significant contributing factors included precipitation seasonality, annual precipitation, and mean temperature of the driest quarter, with cumulative contributions of 60.7%. The total area of suitable habitats of H. concinna was 29.05 × 10⁴ km² in Heilongjiang Province under historical climatic scenarios, with the center of gravity of suitable habitats located at (47.31° N, 129.16° E), while the total area of suitable habitats of H. concinna reduced by 0.97 × 10⁴ km² in Heilongjiang Province under the climatic SSP126 scenario from 2041 to 2060, with the center of gravity shifting to (47.70° N, 129.28° E). Conclusions The distribution of suitable habitats of H. concinna strongly correlates with temperature and humidity in Heilongjiang Province. The total area of potential suitable habitats of H. concinna may appear a tendency towards a decline with climatic changes in Heilongjiang Province, and high-, medium- and low-suitable habitats may shift.
