Cardioembolic stroke is a special type of ischemic stroke caused by cardiac diseases， and its development is closely associated with the structural and functional abnormalities of the heart. The pathophysiological mechanisms of this type of stroke are complex. It is often induced by thrombosis due to cardiac diseases， followed by thrombus detachment and entry into cerebral vessels， leading to ischemic injury and subsequent cascade reactions. Inflammatory response plays a crucial role in the development and progression of cardioembolic stroke， being involved in processes ranging from thrombosis to acute-phase brain injury after embolism， short-term neurological recovery， and long-term prognosis prediction， and can also be used as a biomarker and diagnostic factor. This article summarizes the mechanism by which inflammation contributes to the development and progression of cardioembolic stroke， as well as the current research advances in the etiology of cardioembolic stroke， the recovery of neurological function after stroke， and personalized treatment strategies.

In order to address issues such as the decline in diagnostic performance of deep learning models due to imbalanced data distribution in psoriasis vulgaris,a VGG13-based deep convolutional neural network model is proposed by integrating the processing capability of the improved fuzzy KMeans clustering algorithm for highly clustered complex data and the predictive capability of VGG13 deep convolutional neural network model.The model is applied to the diagnosis of psoriasis vulgaris,and the experimental results indicate that compared with VGG13 and resNet18,the proposed approach based on deep learning and improved fuzzy KMeans is more suitable for identifying psoriasis features.

Objective To observe the value of transesophageal echocardiography(TEE)for guiding left atrial appendage closure(LAAC)with LAmbre occluder.Methods Data of 40 non-valvular atrial fibrillation(NVAF)patients who underwent LA AC with LAmbre occluder were retrospectively analyzed.CT angiography(CTA)before treatment,TEE and digital subtraction angiography(DSA)findings during LAAC were comparatively observed,and the correlations of the anchor area diameter and left atrial appendage opening diameter measured with the above three as well as occluder size were analyzed,and TEE and DSA for evaluating peri-device leak(PDL)were compared.Results LAAC were successfully performed with LAmbre occlude in all 40 cases.The diameter of the fixed umbrella was positively correlated with anchor area diameter measured with CTA,TEE and DSA(r=0.79,0.82,0.91,all P＜0.01),of occlusion umbrella was positively correlated with left atrial appendage opening diameter measured with CTA,TEE and DSA(r=0.56,0.89,0.86,all P＜0.01).Immediately after the release of occluder in LAAC,PDL occurred in 16 cases and were detected with both TEE and DSA,while in the rest 24 cases no PDL was found with neither TEE nor DSA.Conclusion TEE had comparable value to DSA for guiding LAAC using LAmbre occluder.

Objective To design and test the reliability and validity of patient admission nursing assessment sheet of integrated Chinese and westem medicine ward.Methods On the basis of literature research,with traditional Chinese medicine"look,hear,ask and pulse-taking"as the basic framework,physical discrimination as the evaluation outcome,combined with the general nursing evaluation points of patients admitted to hospital,we designed the patient admission nursing assessment sheet of integrated Chinese and westem medicine ward,and then we adopted the Delphi method to conduct an inquiry on the draft of the admission sheet.In April 2022,3 clinical nurses were selected to evaluate 160 admitted patients from Integrated Traditional Chinese and Western Medicine Department of a tertiary A comprehensive hospital in Hubei Province,and Fleiss'Kappa coefficient and content validity coefficient were used to test the reliability and validity.Results The recovery rates of the 2 rounds of expert correspondence questionnaires were 95.45％and 100％.The authority coefficients were 0.931 and 0.957;the Kendall harmony coefficients were 0.101 and 0.106(P＜0.01);the importance scores of articles were 4.13～4.82;the coefficient of variation was 0.07～0.19 in 2nd round of expert correspondence.The final nursing assessment list for inpatients in the integrated Chinese and Western medicine ward included 3 parts:general demographic data assessment,four-Chinese medicine diagnosis assessment/physical discrimination,and nursing risk assessment,and there are 32 evaluation contents in the assessment sheet.The Fleiss'Kappa coefficient of this assessment sheet was 0.602(P＜0.001);the item content validity index was 0.857～1.000,and the overall content validity index was 0.920.Conclusion The admission nursing assessment sheet for inpatients in integrated Chinese and Westem medicine wards has good reliability and validity,and it is suitable for the integrated Chinese and Westem medicine wards.

Objective To investigate the correlation between serum microRNA(miR)-24-3p,microtubule affinity-regulating kinase 4(MARK4)level expression and cardiac function in serum of patients with coronary atherosclerotic heart disease(CHD).Methods From August 2021 to April 2023,138 CHD patients who visited Sichuan Provincial People's Hospital were collected as the study subjects(CHD group).According to the New York Heart Association(NYHA)grading,patients in the CHD group were separated into grade Ⅱ(n=39),grade Ⅲ(n=68),and grade Ⅳ(n=31).Additionally,123 individuals who underwent physical examinations were selected as the health group during the same period.Real-time fluorescence quantitative PCR(qRT-PCR)method was applied to detect the expression levels of miR-24-3p and MARK4.Cardiac function indicators in the CHD and health groups were detected.Pearson method was applied to analyze the correlation among serum miR-24-3p,MARK4,and cardiac function indicators.Results Compared with the healthy group,the levels of MARK4(1.19±0.21 vs 1.00±0.20),left ventricular end-systolic dimension(LVESd),left ventricular enddiastolic dimension(LVEDd),interventricular septal thickness(IVS),left ventricular end-diastolic volume(LVEDv),left ventricular end-systolic volume(LVESv),and left ventricular mass(LV mass)in the CHD group were increased(t=7.462,18.242,23.888,9.941,2.812,12.520,11.029),while the levels of miR-24-3p(0.62±0.11 vs 1.00±0.18),left ventricular ejection fraction(LVEF),and cardiac output(CO)were reduced(t=20.821,10.212,18.188),and the differences were statistically significant(all P＜0.05).As cardiac function grading increased,MARK4 expression levels(1.09±0.19,1.18±0.17,1.32±0.22),LVESd,LVEDd,IVS,LVEDv,LVESv and LV mass were increased(F=13.025,10.606,11.920,57.956,29.680,21.253,12.954),and miR-24-3p expression levels(0.84±0.15,0.61±0.11,0.37±0.08),LVEF and CO were decreased(F=139.227,9.720,13.411),and the differences were statistically significant(all P＜0.05).Pearson correlation analysis showed a negative correlation between miR-24-3p and MARK4 expression in the serum of patients with CHD(r=-0.540,P＜0.05).The relative expression of miR-24-3p in the serum of patients with CHD was negatively correlated with LVESd,LVEDd,IVS,LVEDv,LVESv and LV mass(r=-0.656,-0.636,-0.617,-0.576,-0.492,-0.687,all P＜0.05),but positively correlated with LVEF and CO(r=0.570,0.683,all P＜0.05).The relative expression level of MARK4 was positively correlated with LVESd,LVEDd,IVS,LVEDv,LVESv,and LV mass(r=0.503,0.542,0.508,0.624,0.516,0.560,all P＜0.05),but negatively correlated with LVEF and CO(r=-0.594,-0.525,all P＜0.05).Conclusion The expression of miR-24-3p in the serum of CHD patients was decreased,while the expression of MARK4 was increased.There was an obvious correlation between the two and cardiac function indicators.

Objective To investigate the application of low-dose computed tomography virtual colonoscopy(LDCTVC)in colorec-tal tumor.Methods Forty-seven colorectal tumor were given low-dose CT abdominal scan(low-dose group),15 patients with normal body mass index(BMI)who received routine-dose CT abdominal scan at the same period(routine-dose group).Volume CT dose index(CTDIvol),dose length product(DLP),virtual colonoscopy and optical colonoscopy results were recorded.Results The effective dose with normal BMI was(2.86±0.47)mSv and(4.87±1.15)mSv in the low-dose and routine-dose groups,respectively.The CTDIvol and DLP between the two groups were statistically significant(P＜0.05).There were 14 cases of true positive,4 cases of false positive,5 cases of false negative and 24 cases of true negative in the low-dose group.The sensitivity,specificity and Kappa value of LDCTVC in the diagnosis of colorectal mucosal lesions were 73.7％,85.7％,and 0.6.Conclusion LDCTVC can reduce the effective dose by 50％and has a good diagnostic value for colorectal mucosal lesions,which can make up for the deficiency of colonoscopy and make accurate judgment of extra-mucosal lesions of the bowel wall.

Purpose To investigate the clinical and patho-logical characteristics,molecular characteristics,treatments and prognosis of adenoid cystic carcinoma(AdCC)of the breast.Methods A retrospective analysis was conducted on the clini-cal pathology of 14 breast AdCC patients,and HE,immunohis-tochemistry,FISH testing,and follow-up were performed.Re-sults All cases were female,aged 43～70 years.10 cases of classic AdCC and 4 cases of solid-basal cell AdCC(SB-AdCC)were included.The tumor was composed of epithelial,myoepi-thelial and basal-like cells arranged in sieve,tubular and solid pattern with fibrous mucinous or glassy changes in the stroma.The tumor cells of SB-AdCC were moderately to severely atypical with frequent mitosis and necrosis,accompanied by ductal carci-noma in situ(DCIS).Expression of ER(1/14),PR(1/14),HER2(0/14),CK7(14/14),p63(12/14),CK5/6(14/14),CD117(13/14),MYB(9/14)was detected;Ki67 index was 13.2％and 46.1％in classic AdCC and SB-AdCC,respec-tively.The MYB rearrangement rates in classic AdCC and SB-AdCC were 55.6％(5/9)and 25％(1/4),respectively.All patients were underwent surgical resection and/or radiotherapy and chemotherapy.During the follow-up period(2-62 months),1 SB-AdCC patient died due to lung and liver metasta-sis,while the other 10 patients survived without tumors.Con-clusion SB-AdCC is more invasive than classical AdCC with lower frequency of MYB gene rearrangement,and immunohisto-chemical detection of MYB protein has potential value in assis-ting the diagnosis of SB-AdCC.

This study aims to observe the effect of Panax notoginseng extracts on inflammatory re-sponse in immunosuppressed broilers and to investigate the mechanism through network pharma-cology and molecular docking combined with in vivo animal tests.Based on the TCMSP database and GeneCard and other disease databases,we searched for targets related to Panax notoginseng and broiler inflammation,screened key compounds and targets by applying Cytoscape 3.7.1 and String databases,respectively,and constructed a network relationship diagram of traditional Chi-nese medicine(TCM)-key components-targets,and carried out GO functional enrichment and KEGG pathway enrichment analyses by using the DAVID platform.The GO functional enrichment analysis and KEGG pathway enrichment analysis were carried out by the DAVID platform,visual-ized by the Chiplot online website,and finally,the core clustered proteins were analyzed by Pymol software to obtain the core targets,and molecular docking technology was used to predict the de-gree of matching between the active ingredients and the core targets as well as the animal experi-ments to further explore the pharmacological mechanism of Panax notoginseng extracts.Sixty 1-day-old red-feathered broilers were randomly divided into three groups(LPS group,CON group,and PN group),and the test period was 35 days.The LPS and PN groups were injected intraperito-neally with 250 μg/kg body weight of LPS,and the CON group was injected with an equal amount of sterile physiological saline on the 12,14,33,and 35 d.The LPS and PN groups were injected with 250 μg/kg body weight of LPS,and the CON group was injected with an equal amount of sterile physiological saline.The effect of Panax notoginseng extract on inflammatory cytokines in serum was detected by ELISA,and the hormone content in serum was also detected in each group,and fluorescence quantitative PCR was used to detect the effect of each group on the mRNA ex-pression levels of STAT3,IL-6,and CASP3.The results showed that the serum levels of IFN-γ,IL-6,iNOS,TNF-α,and TNF-β were significantly increased(P＜0.05),while the level of IL-10 was significantly decreased(P＜0.05)after LPS tapping at weeks 2 and 5.The serum levels of IFN-y,IL-6,iNOS,TNF-α,and TNF-β were significantly decreased(P＜0.05)and IL-10 was sig-nificantly increased(P＜0.05)by the addition of Panax ginseng extracts to the basal diet com-pared with the LPS group.Panax notoginseng extracts significantly decreased the serum levels of adrenocorticotropic hormone(ACTH)and corticosterone(CORT)(P＜0.05)and increased the levels of growth hormone(GH)(P＜0.05).A total of 8 active ingredients and 123 potential tar-gets for broiler inflammation were predicted by network pharmacology.The protective mechanism of Panax notoginseng against broiler inflammation may be related to the C-type lectin receptor(CLR)signaling pathway,Toll-like receptor(TLR)signaling pathway,MAPK signaling pathway,NOD-like receptor(NLR)signaling pathway,and FoxO signaling pathway.According to the pre-diction,the alleviation of inflammatory response in broiler chickens by Panax notoginseng may be related to the action on 12 key targets.Fluorescence quantitative PCR showed that Panax notogin-seng extract down-regulated the mRNA expression of IL-6 and CASP3(P＜0.05)and up-regula-ted that of STAT3(P＜0.05),and molecular docking results also showed that the active ingredi-ents in Panax notoginseng extracts could exert anti-inflammatory effects through IL-6 and CASP3.The results suggested that Panax quinquefolium extracts might alleviate the inflammatory response of immune-stressed broilers through multi-components,multi-targets,and multi-path-ways,and this study helps propose new therapeutic strategies and provides a theoretical basis for the development of feed additives based on Penthorum chinense Pursh extract.
