Objective To compare the effects of dexmedetomidine and midazolam on intraoperative blood pressure and postoperative 90-day outcome of endovascular treatment(EVT)in patients with acute anterior circulation large vessel occlusive stroke.Methods Retrospective consecutive patients with acute anterior circulation large vessel occlusion stroke who received EVT within 24 hours of onset,admitted to the Department of Neurology at the Second People's Hospital of Hefei from January 2024 to February 2025 were included.Patients were divided into the dexmedetomidine group and the midazolam group based on the choice of sedative in EVT.Baseline and clinical data were collected from patients,including sex,age,medical history(hypertension,diabetes,atrial fibrillation,stroke history),smoking history,blood pressure at admission(systolic,diastolic,mean arterial pressure),National Institutes of Health stroke scale(NIHSS)score at admission,trial of Org 10172 in acute stroke treatment(TOAST)classification,and site of vascular occlusion(internal carotid artery,M1 segment of the middle cerebral artery).Procedure related parameters,including intravenous thrombolysis before EVT,intraoperative use of tirofiban,modified thrombolysis in cerebral infarction(mTICI)grade,thrombectomy techniques(stent-retriever thrombectomy,aspiration thrombectomy,combined stent-retriever and aspiration thrombectomy,and other salvage measures),number of thrombectomy,time from onset to revascularization,time from puncture to revascularization,blood pressure during EVT(minimum systolic,minimum diastolic,and minimum mean arterial pressure),and blood pressure at the end of EVT(systolic,diastolic,and mean arterial pressure).The primary outcome was good prognosis at 90 days after EVT(modified Rankin scale score of 0-2 at 90 days),while secondary outcome was＞20％decrease in mean arterial pressure during EVT,early neurological improvement(ENI;a decrease on NIHSS score no less than 8 or a reduction of NIHSS score to 0-1 at 24 hours after EVT),and early neurological deterioration(END;an increase of more than 2 points on the NIHSS at 24 hours after procedure).Safety outcomes included any intracranial hemorrhage within 48 hours after EVT,symptomatic intracranial hemorrhage within 48 hours after EVT(sICH;intracranial hemorrhage confirmed by head CT leading to neurological deterioration,with an increase in NIHSS score of at least 4 points,or the presence of potentially fatal intracranial hemorrhage on head CT),pneumonia within 2 weeks after EVT,and the 90-day mortality after EVT.The baseline and clinical data,EVT conditions,primary outcome,secondary outcome,and safety indicators were compared between the two groups.Univariate Logistic regression analysis was used to screen the variables associated with a decrease in mean arterial pressure＞20％during EVT in patients with acute anterior circulation large vessel occlusive stroke.Variables with P＜0.15 and those considered potentially influential based on clinical experience were included in multivariate Logistic regression analysis to identify predictors of a＞20％decrease in mean arterial pressure during EVT in patients with acute anterior circulation large vessel occlusive stroke.Results A total of 93 patients with acute anterior circulation large vessel occlusive stroke who underwent EVT were included,comprising 51 males and 42 females,aged 34 to 99 years,with an average of(71±13)years old.Among them,63 patients were in the dexmedetomidine group,and 30 patients were in the midazolam group.33 patients showed＞20％decreases in mean arterial pressure during EVT,while 60 patients had ≤20％decreases.(1)Compare with the midazolam group,the proportion of female patients in the dexmedetomidine group was lower(36.5％[23/63]vs.63.3％[19/30],P=0.015),and the age was younger([69±13]years vs.[77±13]years,P=0.005).There were no statistically significant differences in other baseline and clinical data(all P＞0.05).(2)In comparison with the midazolam group,the dexmedetomidine group had a higher proportion of patients with more thrombectomy procedures(1.00[1.00,2.00]times vs.1.00[1.00,1.25]times,P=0.011),END(27.0％[17/63]vs.6.7％[2/30],P=0.023),sICH within 48 hours(19.0％[12/63]vs.3.3％[1/30],P=0.041),and a decrease in mean arterial pressure＞20％during EVT(42.9％[27/63]vs.20.0％[6/30],P=0.031).There were no statistically significant differences in the remaining EVT conditions,primary outcome,secondary outcome,and safety indicators(all P＞0.05).(3)The results of univariate Logistic regression analysis showed that diastolic blood pressure at admission(P=0.002),mean arterial pressure at admission(P=0.009),and dexmedetomidine sedation(P=0.036)were the influencing factors of a decrease＞20％in mean arterial pressure during EVT in patients with acute anterior circulation large vessel occlusion stroke.(4)The results of multivariate Logistic regression analysis showed that dexmedetomidine sedation(OR,3.271,95％CI 1.057-10.126,P=0.040)and higher diastolic blood pressure on admission(OR,1.105,95％CI 1.006-1.213,P=0.037)were independent predictors of a decrease over 20％in mean arterial pressure during EVT in patients with acute anterior circulation large vessel occlusive stroke.Conclusions Dexmedetomidine is an independent predictor of an over 20％decrease in mean arterial pressure during EVT in patients with acute anterior circulation large vessel occlusive stroke,but there is no statistically significant differences in the rate of good neurological function at 90 days and 90-day mortality postoperatively between the two groups.Further prospective randomized controlled studies are needed.

Objective To understand the current situation of healthcare-associated infection(HAI)in China,pro-vide data support and decision-making basis for formulating scientific and effective strategies for HAI prevention and control.Methods A nationwide cross-sectional survey on HAI was conducted among various types and levels of medical institutions in China according to a unified protocol of bedside surveys and case investigations.Results In 2024,a total of 5 736 medical institutions and 2 751 765 patients were surveyed.Among them,34 889 HAI cases were identified,with a prevalence rate of 1.27％.The number of HAI episodes was 38 032,and case prevalence rate was 1.38％.The prevalence rate of HAI in medical institutions in different regions of China ranged from 0.66％to 2.35％.Among medical institutions of different scales,those with a bed capacity of ≥900 had the high-est incidence of HAI,reaching 1.65％.The most common infection site was the lower respiratory tract(44.66％),followed by the urinary tract(12.94％),surgical site(9.32％),upper respiratory tract(7.02％),and bloodstream infection(5.78％).The top 3 departments with the highest HAI rates were the general intensive care unit(10.02％),department of neurosurgery(5.51％),and department(group)of hematology(5.34％).A total of 23 238 strains of HAI pathogens were detected,with 10 714 strains(46.10％)from lower respiratory tract speci-mens.The top 5 detected strains were Klebsiella pneumoniae(14.76％),Pseudomonas aeruginosa(13.33％),Escherichia coli(12.79％),Acinetobacter baumannii(9.23％),and Staphylococcus aureus(7.88％).231 944 pa-tients underwent class Ⅰ incision surgery were monitored,with 1 647 cases experienced surgical site infection,and the prevalence rate of surgical site infection was 0.71％.The number of patients who should undergo pathogen de-tection(patients receiving therapeutic and therapeutic combined prophylactic antimicrobial agents)was 715 179,while the actual number was 480 492,with a pathogen detection rate of 67.18％.425 225 patients received patho-genic detection before treatment,with a detection rate of 59.46％.Conclusion The overall HAI prevalence in Chi-na is lower,showing disparities among medical institutions of different regions and scales.Therefore,precise imple-mentation of measures is necessary for HAI prevention and control,with a focus on high-risk institutions and high-risk departments,key areas,and critical procedures.All levels of medical institutions should continuously reduce the incidence of HAI by strengthening monitoring,standardizing the use of antimicrobial agents,and reinforcing basic HAI prevention and control measures.

Chimeric antigen receptor(CAR)T cell therapy has made a major breakthrough in the treatment of hematological malignancies.However,more and more studies have shown that factors such as T-cell exhaustion,tumor antigen modulation,immunosuppressive tumor microenvironment,and CAR-T cell dysfunction can lead to relapse and CAR-T cell resistence in hematologic malignancies.Developing dual-targeted CAR-T cells,exploring new immune targets,blocking CAR-T cell exhaustion,combining CAR-T cells with other therapies,implementing bridging therapies,and designing novel immunotherapies may be strategies to address CAR-T cell resistance.This article reviews the mechanisms of resistance to CAR-T cell therapy in hematological malignancies and the corresponding coping strategies.

Objective To investigate the correlation between the hemoglobin glycation index(HGI)and the severity of intraplaque neovascularization(IPN)in patients with mild-to-moderate carotid artery stenosis.Methods This study retrospectively and consecutively enrolled patients with mild-to-moderate carotid artery stenosis(＜70%narrowing)hospitalized in the Department of Neurology at the Hefei Second People's Hospital between June,2020 and June,2024.Demographic data(age,gender),personal history(smoking,drinking),cerebrovascular risk factors(hypertension,diabetes,hyperlipidemia),body mass index,and laboratory indicators from fasting venous blood collected on the second morning of hospital admission(neutrophils,lymphocytes,neutrophil-to-lymphocyte ratio,platelet count,total cholesterol,triglycerides,high-density lipoprotein cholesterol,low-density lipoprotein cholesterol(LDL-C),homocysteine,blood glucose,and glycated hemoglobin[HbA1c])were collected and compared.A univariate linear regression analysis was performed to assess the relationship between fasting blood glucose and HbA1c levels measured on the second day after admission,yielding the prediction formula:predicted HbA1c(%)=0.571×fasting blood glucose(mmol/L)+3.125.Subsequently,HGI was calculated through:HGI=actual HbA1c-predicted HbA1c.Carotid ultrasound was used to measure patients'carotid intima-media thickness,and,plaque location,thickness(maximum plaque diameter),length,echogenicity,and resistance index.For patients with multiple plaques,the thickest plaque was selected as the target plaque.Using the AngioPLUS mode of carotid ultrasound,dynamically observe for presence of IPN at the filling defect of the carotid artery plaque.The IPN condition of the target plaque was then assessed,including the number,location,morphology(e.g.,punctate,short linear,etc.),and spectral Doppler characteristics of the new blood vessels.The IPN signals were counted and scored according to the following criteria:absence of high-echogenicity blood flow signals in the target carotid artery plaque indicating no neovascularization,was scored as 0 point;the presence of fewer than 4 punctate or short linear hyperechoic blood flow signals within the target plaque was scored as 1 point;the presence of diffusely distributed(≥4)short linear or strip-like hyperechoic blood flow signals within the plaque was scored as 2 points.A higher IPN score indicates a more severe degree of IPN.Patients with an IPN score of 0-1 were categorized as the low IPN score group,while those with an IPN score of 2 were classified as the high IPN score group.Indicators with statistically significant differences between the two groups in the univariate analysis and exhibited no multicollinearity were included in the multivariate binary Logistic regression model to analyze the relationship between HGI and the severity of carotid IPN.Results A total of 387 patients(222 males and 165 females,with a mean age of[70±10]years)with mild-to-moderate carotid artery stenosis were included in this study.Among the 387 patients enrolled,97 were in the low IPN score group,while 290 were in the high IPN score group.(1)The high IPN score group exhibited significantly higher average age([71±10]years vs.[67±10]years),higher prevalence of hypertension(79.7%[231/290]vs.67.0%[65/97]),higher prevalence of diabetes(37.6%[109/290]vs.14.4%[14/97]),greater plaque thickness(2.40[2.00,3.10]mm vs.2.30[1.80,2.70]mm),higher HbA1c levels(6.25%[5.70%,7.20%]vs.5.80%[5.50%,6.40%]),and higher HGI values(-0.05%[-0.39%,0.46%]vs.-0.29%[-0.56%,-0.10%])in comparison to the low IPN score group(all P＜0.05).Additionally,the high IPN score group had significantly lower lymphocyte ratios([27.75±9.19]%vs.[30.17±9.04]%)and lower LDL-C levels([2.19±0.81]mmol/L vs.[2.43±0.91]mmol/L;both P＜0.05).(2)The results of multivariate Logistic regression analysis indicated that age(OR,1.031,95%CI 1.004-1.060,P=0.027),HGI(OR,1.782,95%CI 1.066-2.979,P=0.028),and plaque thickness(OR,1.750,95%CI 1.229-2.490,P=0.002)were independent influencing factors associated with the severity of IPN in the mild-to-moderate carotid artery stenosis.Conclusions High HGI may serve as an independent risk factor for the severe IPN in patients with mild-to-moderate carotid artery stenosis.However,the findings of this study require further validation through multi-center,large-scale,prospective clinical trials.

Sarcopenia is an age-related syndrome characterized by progressive and widespread loss of skeletal muscle mass and/or decline in muscle function.Its incidence increases year by year with aging and is influenced by multiple factors,including genetic background,lifestyle,nutritional status,and chronic diseases.Recent studies have revealed a significant correlation between sarcopenia and chronic coronary syndromes(CCS),not only in terms of the frequency of occurrence but also the se-verity of the conditions.Moreover,sarcopenia and CCS share common pathogenic mechanisms,en-compassing various pathophysiological processes such as chronic inflammation,oxidative stress,apop-tosis,and insulin resistance.This article aimed to review the current research progress on comorbidity relationship between sarcopenia and CCS,explore their shared pathophysiological basis,and discuss their impacts on clinical prognosis.

This study identified blood-entering components of Anshen Dropping Pills and explored their anti-insomnia effects and mechanisms. The main blood-entering components of Anshen Dropping Pills were detected and identified by UPLC-Q-TOF-MS/MS. The rationality of the formula was assessed by using enrichment analysis based on the relationship between drugs and symptoms, and core targets of its active components were selected as the the potential anti-insomnia targets of Anshen Dropping Pills through network pharmacology analysis. Furthermore, protein-protein interaction(PPI) network, Gene Ontology(GO) enrichment analysis, and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway analysis were performed on the core targets. An active component-core target network for Anshen Dropping Pills was constructed. Finally, the effects of low-, medium-, and high-dose groups of Anshen Dropping Pills on sleep episodes, sleep duration, and sleep latency in mice were measured by supraliminal and subliminal pentobarbital sodium experiments. Moreover, total scores of the Pittsburgh sleep quality index(PSQI) scale was used to evaluate the changes before and after the treatment with Anshen Dropping Pills in a clinical study. The enrichment analysis based on the relationship between drugs and symptoms verified the rationality of the Anshen Dropping Pills formula, and nine blood-entering components of Anshen Dropping Pills were identified by UPLC-Q-TOF-MS/MS. The network proximity revealed a significant correlation between eight components and insomnia, including magnoflorine, liquiritin, spinosin, quercitrin, jujuboside A, ginsenoside Rb_3, glycyrrhizic acid, and glycyrrhetinic acid. Network pharmacology analysis indicated that the major anti-insomnia pathways of Anshen Dropping Pills involved substance and energy metabolism, neuroprotection, immune system regulation, and endocrine regulation. Seven core genes related to insomnia were identified: APOE, ALB, BDNF, PPARG, INS, TP53, and TNF. In summary, Anshen Dropping Pills could increase sleep episodes, prolong sleep duration, and reduce sleep latency in mice. Clinical study results demonstrated that Anshen Dropping Pills could decrease total scores of PSQI scale. This study reveals the pharmacodynamic basis and potential multi-component, multi-target, and multi-pathway effects of Anshen Dropping Pills, suggesting that its anti-insomnia mechanisms may be associated with the regulation of insomnia-related signaling pathways. These findings offer a theoretical foundation for the clinical application of Anshen Dropping Pills.

This study aims to investigate the effect of Chaijin Jieyu Anshen Formula on the neuroinflammation of rats with insomnia complicated with depression through the regulation of triggering receptor expressed on myeloid cells 2(TREM2)/complement protein C1q signaling pathway. Rats were randomly divided into a normal group, a model group, a positive drug group, as well as a high, medium, and low-dose groups of Chaijin Jieyu Anshen Formula, with 10 rats in each group. Except for the normal group, the other groups were injected with p-chlorophenylalanine and exposed to chronic unpredictable mild stress to establish the rat model of insomnia complicated with depression. The sucrose preference experiment, open field experiment, and water maze test were performed to evaluate the depression in rats. Enzyme-linked immunosorbent assay was employed to detect serum 5-hydroxytryptamine(5-HT), dopamine(DA), and norepinephrine(NE) levels. Hematoxylin and eosin staining and Nissl staining were used to observe the damage in nucleus accumbens neurons. Western blot and immunofluorescence were performed to detect TREM2, C1q, postsynaptic density 95(PSD-95), and synaptophysin 1(SYN1) expressions in rat nucleus accumbens, respectively. Golgi-Cox staining was utilized to observe the synaptic spine density of nucleus accumbens neurons. The results show that, compared with the model group, Chaijin Jieyu Anshen Formula can significantly increase the sucrose preference as well as the distance and number of voluntary activities, shorten the immobility time in forced swimming test and the successful incubation period of positioning navigation, and prolong the stay time of space exploration in the target quadrant test. The serum 5-HT, DA, and NE contents in the model group are significantly lower than those in the normal group, with the above contents significantly increased after the intervention of Chaijin Jieyu Anshen Formula. In addition, Chaijin Jieyu Anshen Formula can alleviate pathological damages such as swelling and loose arrangement of tissue cells in the nucleus accumbens, while increasing the Nissl body numbers. Chaijin Jieyu Anshen Formula can improve synaptic damage in the nucleus accumbens and increase the synaptic spine density. Compared to the normal group, the expression of C1q protein was significantly higher in the model group, while the expression of TREM2 protein was significantly lower. Compared to the model group, the intervention with Chaijin Jieyu Anshen Formula significantly downregulated the expression of C1q protein and significantly upregulated the expression of TREM2. Compared with the model group, the PSD-95 and SYN1 fluorescence intensity is significantly increased in the groups receiving different doses of Chaijin Jieyu Anshen Formula. In summary, Chaijin Jieyu Anshen Formula can reduce the C1q protein expression, relieve the TREM2 inhibition, and promote the synapse-related proteins PSD-95 and SNY1 expression. Chaijin Jieyu Anshen Formula improves synaptic injury of the nucleus accumbens neurons, thereby treating insomnia complicated with depression.
