Objective To discuss the current status of the discharge readiness in patients with Budd-Chiari syndrome undergoing interventional therapy,and to analyze its influencing factors.Methods A cross-sectional survey in 150 patients with Budd-Chiari syndrome,who were admitted to the Department of Interventional Radiology of a certain grade Ⅲ-A hospital in Xuzhou City of China between September 2022 and September 2023,was conducted.The revised Discharge Preparation Scale,the Discharge Guidance Quality Scale,and the self-designed general data collection form were used as the study tools.Results The results of the survey showed that the mean discharge readiness score in the 150 patients with Budd-Chiari syndrome undergoing interventional therapy was(102.59±7.88)points,and the quality of discharge guidance,education level,and per capita monthly household income,and the current disease status were the key factors affecting the patient's readiness for discharge(P＜0.001).Conclusion The overall level of readiness for discharge in patients with Budd-Chiari syndrome undergoing interventional therapy is high,but nurses should make key assessment of the current disease status,the discharge intentions and concerns of patients with low-education level and low-income,based on which give targeted health guidance so as to improve patient's readiness for discharge.(J Intervent Radiol,2024,33:674-678)

Alzheimer's disease(AD),the most common progressive neurodegenerative disease in dementia,is also a special lipid disease.From the perspective of modern medicine,cholesterol homeostasis is an important risk factor for AD.Amyloid-beta plaque deposition,neurofibrillary tangles,and large amount of lipid granule accumulation are typical pathological features of AD.From the perspective of TCM,turbidity is the key to the pathogenesis of AD.Phlegm turbid,stasis turbid and turbid toxin are the concrete derivation of turbidity,which are the standard of AD.Cholesterol is the greasy lipid which is produced from of the essence of water and food,the disturbance of cholesterol homeostasis is a typical embodiment of the pathogenesis mechanism of endogenous turbidity.Regulating cholesterol homeostasis by traditional Chinese medicine may be a new direction for the treatment of AD in the future.Focusing on the modern research of cholesterol homeostasis,taking the theory of turbidity as the starting point,this paper analyzed the correlation between the connotation of turbidity theory and the imbalance of cholesterol homeostasis as well as the pathogenesis mechanism,and further elucidated the clinical application results in the treatment of AD from the aspects of phlegm turbid,stasis turbid and turbid toxin,so as to better guide clinical practice and scientific research.

Objective:To investigate the tissue methylation features of adenocarcinoma patients presenting as pulmonary nodules on CT scans.Methods:A retrospective analysis was conducted on 70 adenocarcinoma patients with pulmonary nodules diagnosed at the Shanghai General Hospital from June 1, 2022 to January 20, 2024. Participants were assigned to two groups using the random number table, with 40 in the discovery group and 30 in the validation group. In the discovery group, tissue samples were analyzed using reduced representation bisulfite sequencing (RRBS) technology to compare the average methylation levels between cancer tissues and paired adjacent non-cancerous tissues. Differentially methylated regions (DMRs) were screened for analysis of their distribution across various genomic functional elements, and hierarchical clustering was plotted. GO and KEGG pathway enrichment analyses were further conducted on the DMRs. Subsequently, candidate DMRs associated with lung adenocarcinoma were validated using TCGA lung adenocarcinoma cohort and targeted bisulfite sequencing technology in the validation group. The comparison of methylation levels between groups was conducted using t-tests or non-parametric tests, while rates and composition ratios were analyzed using chi-square tests or Fisher′s exact test.Results:In discovery cohort, the average methylation level in cancer tissues was lower compared to adjacent normal tissues [(42.369±4.627) vs (44.370±4.046), t=?2.059, P=0.043]. A total of 37 995 DMRs were identified, including 16 889 upregulated regions and 21 106 downregulated regions, predominantly locating in promoter regions (48.917%), introns (36.457%), and exons (10.812%). The DMR clustering heatmap revealed two distinct clusters corresponding to cancer tissues and adjacent non-cancerous tissues. GO analysis showed that DMRs associated genes were mainly located in the cell membrane and nuclear chromatin, and were primarily involved in RNA polymerase Ⅱ-related transcription and regulation. KEGG pathway enrichment analysis indicated that DMRs associated genes were mainly involved in neuroactive ligand-receptor interaction, cancer pathways, calcium signaling pathway, cAMP signaling pathway, and MAPK signaling pathway. Validation in the TCGA cohort confirmed 11 potential characteristic DMRs. In the validation group, TBS confirmed that the methylation levels of DMRs associated with MIR10B, DMRTA2, HOPX, TFAP2B and MARCH11 in cancer tissues were significantly higher than those in adjacent non-cancerous tissues [11.200(4.305, 27.088) vs 2.650(1.298, 4.645), Z=?4.539, P<0.05; 18.610(13.600, 33.025) vs 8.675(5.488, 13.085), Z=?4.554, P<0.05; 17.600(2.183, 76.015) vs 1.085(0.898, 1.835), Z=?5.131, P<0.05; 5.250(3.220, 7.693) vs 3.495(2.165, 4.383), Z=?2.861, P<0.05; 11.515(7.525, 21.033) vs 7.830(5.518, 11.488), Z=?2.440, P<0.05 ], and the differences were statistically significant. Conclusions:Lung adenocarcinoma tissue exhibits different methylation patterns compared with adjacent normal lung tissue. The identified DMRs are involved in the regulation of several key pathways. Results from the TCGA cohort and an independent validation group support the potential diagnostic value of DMRs such as MIR10B, DMRTA2, HOPX, TFAP2B, and MARCH11 in lung adenocarcinoma, though their clinical application requires further validation.

Objective To summarize and analyze the application of regional citrate anticoagulation (RCA) in patients undergoing continuous renal replacement therapy (CRRT) using a scoping review methodology. Methods Following the scoping review methodology, a systematic search was conducted in domestic and international databases, including CNKI, Wanfang Data, Cochrane Library, PubMed, and Embase for literature related to RCA in CRRT patients. The search was limited from the inception of the databases to August 10, 2023. Included studies were screened, summarized, and analyzed. Results A total of 19 articles were included in this study, comprising 8 randomized controlled trials, 8 cohort studies, 2 case-control studies, and 1 cross-sectional survey. Anticoagulation methods for CRRT primarily included unfractionated heparin, low-molecular-weight heparin, thrombin inhibitors, nafamostat, and RCA. Compared to other anticoagulation methods, RCA exhibited advantages in lower bleeding risk and longer filter lifespan. Calcium ion monitoring during RCA application predominantly relies on the empirical trial-and-error approach. Major complications associated with RCA include citrate accumulation, acid-base imbalance, and ion metabolic disorders. For patients with high bleeding risk, hypercalcemia, and sepsis, RCA may confer greater benefits during CRRT. Conclusion RCA has gradually emerged as a preferred anticoagulation method for CRRT patients, offering advantages in extending filter lifespan and reducing bleeding risk. Future research should focus on calcium ion monitoring during RCA, enhancing safety and efficacy through targeted infusion systems, and further exploring the immunomodulatory effects of RCA and its mechanisms related to high inflammatory factor clearance rates.

Objective:To explore the changes and influencing factors of psychological distress in patients with primary acute myocardial infarction (AMI) in different periods, and to provide reference for the management of psychological distress in patients with primary AMI.Methods:This was a longitudinal, prospective, observational study. From June 2021 to September 2022, 118 patients with primary AMI in Peking Union Medical College Hospital and Peking University First Hospital were selected as the research objects. The psychological distress level of patients was investigated on the points of 24 hours after illness (T 1), before discharge (T 2), 1 month after discharge (T 3), 3 months after discharge (T 4), 6 months after discharge (T 5) and 12 months after discharge (T 6), and the influencing factors were analyzed. Results:The detection rate of psychological distress in 6 follow-up survey nodes was 66.95% (79/118), 48.31% (57/118), 29.66% (35/118), 24.58% (29/118), 19.49% (23/118) and 15.25% (18/118) respectively. Education level, family per capita income and disease awareness had significant effects on the psychological distress of patients with primary AMI at the time points from T 1 to T 6 ( β values were - 1.262 to - 0.212, all P<0.05). Conclusions:The level of psychological distress in primary AMI patients decreased with time. Nursing staff should pay attention to the trajectory and influencing factors of psychological pain, and formulate targeted intervention measures to reduce the level of psychological pain and promote the comprehensive rehabilitation of patients.

OBJECTIVE Cognitive deficit is a com-mon comorbidity in temporal lobe epilepsy(TLE)and that is not well controlled by current therapeutics.Currently,how epileptic seizure affects cognitive performance remains largely unclear.The subiculum is the major out-put of the hippocampus,which projects to entorhinal cor-tex and other more distinct brain regions.Physiologically,the subiculum codes spatial working memory and naviga-tion information including place,speed,and trajectory.Importantly,prior studies have noted the importance of the subiculum in the beginning,spreading,and generaliz-ing process of hippocampal seizure.How seizure-activated neurons in subiculum participate in cognitive impairment remains largely elusive.METHODS In this study,we sought to label the subicular seizure-activated c-fos+ neu-rons with a special promoter with enhanced synaptic activity-responsive element E-SARE in the subiculum,combined with chemogenetics and designer receptors exclusively activated by designer drugs(DREADDs),Ca2+ fiber photometry approaches,and behavioral tasks,to reveal the role of these neurons in cognitive impairment in epilepsy.RESULTS We found that chemogenetic inhibi-tion of subicular seizure-tagged c-fos+ neurons(mainly CaMK Ⅱ α+ glutamatergic neurons)alleviates seizure generalization and improves cognitive performance in the hippocampal CA3 kindling TLE model.While inhibition of seizure-labeled c-fos+ GABAergic interneuron shows no effect on seizure and cognition.As a comparison,che-mogenetic inhibition of the whole subicular CaMK Ⅱ α+ neuron impairs cognitive function in na?ve mice in basal condition.Notably,inhibition of subicular seizure-tagged c-fos+ neurons enhances the recruitment of cognition-responsive c-fos+ neurons via increasing neural excitability during cognition tasks.CONCLUSION Our results dem-onstrate that subicular seizure-activated c-fos+ neurons contribute to cognitive impairment in TLE,suggesting sei-zure-tagged c-fos+ neurons as the potential therapeutic target to alleviate cognitive impairment in TLE.

The rearranged during transfection (RET) is a receptor protein tyrosine kinase. Oncogenic RET fusions or mutations are found most often in non-small cell lung cancer (NSCLC) and in thyroid cancer, but also increasingly in various types of cancers at low rates. In the last few years, two potent and selective RET protein tyrosine kinase inhibitors (TKIs), pralsetinib (BLU-667) and selpercatinib (LOXO-292, LY3527723) were developed and received regulatory approval. Although pralsetinib and selpercatinib gave high overall response rates (ORRs), < 10% of patients achieved a complete response (CR). The RET TKI-tolerated residual tumors inevitably develop resistance by secondary target mutations, acquired alternative oncogenes, or MET amplification. RET G810 mutations located at the kinase solvent front site were identified as the major on-target mechanism of acquired resistance to both selpercatinib and pralsetinib. Several next-generation of RET TKIs capable of inhibiting the selpercatinib/pralsetinib-resistant RET mutants have progressed to clinical trials. However, it is likely that new TKI-adapted RET mutations will emerge to cause resistance to these next-generation of RET TKIs. Solving the problem requires a better understanding of the multiple mechanisms that support the RET TKI-tolerated persisters to identify a converging point of vulnerability to devise an effective co-treatment to eliminate the residual tumors.

Numerous studies have reported that the resistance of biofilm bacteria to antibiotics can be up to 10-1 000 fold higher than that of planktonic bacteria. Bacterial biofilms are reported to be responsible for more than 80% of human microbial infection, posing great challenges to the healthcare sector. Many studies have reported that plant extracts and their active ingredients can inhibit the formation and development of bacterial biofilms, including reducing biofilm biomass and the number of viable bacteria in biofilms, as well as eradicating mature biofilms. This review summarized the plant extracts and their active ingredients that are inhibitory to bacterial biofilms, and analyzed the underpinning mechanisms. This review may serve as a reference for the development of plant drugs to prevent and treat biofilm infections.

Objective:To analyze the abnormal vestibular function of Wernicke encephalopathy (WE) and to explore its diagnostic value.Methods:WE patients who visited the Vertigo Center of the Second Affiliated Hospital of Zhengzhou University from January 2018 to January 2021 were retrospectively collected. All patients were evaluated by clinical neurology. Before treatment, all patients completed video head impulse test (vHIT) and video nystagmusgraphy (VNG) in addition to cranial magnetic resonance and serum thiamine level examination.Results:All 12 patients had a history of eating defects, including 8 cases of alcoholism. All 12 patients had walking instability, 7 cases had dizziness and 8 cases had oscillopsia. Six cases had ophthalmoplegia. All 12 cases showed positive gaze nystagmus. The pathological saccades of bilateral horizontal semicircular canals were found in 12 patients by vHIT before treatment, but there was only 1 patient showing abnormality in vertical semicircular canals, the difference being statistically significant ( P<0.05). All patients could detect bilateral, horizontal, gaze-evoked nystagmus, including 3 cases with vertical nystagmus, 1 case with abnormal saccade test, 3 cases with abnormal smooth tracking test and 1 case with abnormal optokinetic test. There were abnormalities in the caloric test, including 6 cases of bilateral dysfunction and 2 cases of unilateral dysfunction. Conclusions:WE patients may have abnormal vHIT and bilateral, horizontal, gaze-evoked nystagmus, which is similar to the special abnormal signs of simultaneous damage of both peripheral and central vestibular dysfunction.Vestibular function test is valuable for diagnosis of WE, and it is suitable for patients with a history of nutritional disorders who have dizziness or walking instability and suspected WE.
