Rosuvastatin(RVS)is an excellent drug with anti-inflammatory and lipid-lowering properties in the aca-demic and medical fields.However,this drug faces a series of challenges when used to treat atherosclerosis caused by hyperhomocysteinemia(HHcy),including high oral dosage,poor targeting,and long-term toxic side effects.In this study,we applied nanotechnology to construct a biomimetic nano-delivery system,macrophage membrane(M?m)-coated RVS-loaded Prussian blue(PB)nanoparticles(MPR NPs),for improving the bioavailability and targeting capacity of RVS,specifically to the plaque lesions associated with HHcy-induced atherosclerosis.In vitro assays demonstrated that MPR NPs effectively inhibited the Toll-like receptor 4(TLR4)/hypoxia-inducible factor-1α(HIF-1α)/nucleotide-binding and oligomerization domain(NOD)-like receptor thermal protein domain associated protein 3(NLRP3)signaling pathways,reducing pyroptosis and inflammatory response in macrophages.Additionally,MPR NPs reversed the abnormal distribution of adenosine triphosphate(ATP)-binding cassette transporter A1(ABCA1)/ATP binding cassette transporter G1(ABCA1)/ATP binding cassette transporter G1(ABCG1)caused by HIF-1α,promoting cholesterol efflux and reducing lipid deposition.In vivo studies using apolipoprotein E knockout(ApoE-/-)mice confirmed the strong efficacy of MPR NPs in treating atherosclerosis with favorable bio-security,and the mechanism behind this efficacy is believed to involve the regulation of serum metabolism and the remodeling of gut microbes.These findings suggest that the synthesis of MPR NPs provides a promising nanosystem for the targeted therapy of HHcy-induced atherosclerosis.

Objective:To explore the prognostic predictive value of deep neural network (DNN) assisted myocardial contrast echocardiography (MCE) quantitative analysis of ST-elevated myocardial infarction (STEMI) patients after successful percutaneous coronary intervention(PCI).Methods:A retrospective analysis was performed in 97 STEMI patients with thrombolysis in myocardial infarction-3 flow in infarct vessel after primary PCI in Renmin Hospital of Wuhan University from June to November 2021. MCE was performed within 48 h after PCI. Patients were followed up to 120 days. The adverse events were defined as cardiac death, hospitalization for congestive heart failure, reinfarction, stroke and recurrent angina. The framework consisted of the U-net and hierarchical convolutional LSTMs. The plateau myocardial contrast intensity (A), micro-bubble rate constant (β), and microvascular blood flow (MBF) for all myocardial segments were obtained by the framework, and then underwent variability analysis. Patients were divided into low MBF group and high MBF group based on MBF values, the baseline characteristics and adverse events were compared between the two groups. Other variables included biomarkers, ventricular wall motion analysis, MCE qualitative analysis, and left ventricular ejection fraction. The relationship between various variables and prognosis was investigated using Cox regression analysis. The ROC curve was plotted to evaluate the diagnostic efficacy of the models, and the diagnostic efficacy of the models was compared using the integrated discrimination improvement index (IDI).Results:The time-cost for processing all 3 810 frames from 97 patients was 377 s. 92.89% and 7.11% of the frames were evaluated by an experienced echocardiographer as "good segmentation" and "correction needed". The correlation coefficients of A, β, and MBF ranged from 0.97 to 0.99 for intra-observer and inter-observer variability. During follow-up, 20 patients met the adverse events. Multivariate Cox regression analysis showed that for each increase of 1 IU/s in MBF of the infarct-related artery territory, the risk of adverse events decreased by 6% ( HR 0.94, 95% CI =0.91-0.98). There was a 4.5-fold increased risk of adverse events in the low MBF group ( HR 5.50, 95% CI=1.55-19.49). After incorporating DNN-assisted MCE quantitative analysis into qualitative analysis, the IDI for prognostic prediction was 15% (AUC 0.86, sensitivity 0.78, specificity 0.73). Conclusions:MBF of the area supplied by infarct-related artery after STEMI-PCI is an independent protective factor for short-term prognosis. The DNN-assisted MCE quantitative analysis is an objective, efficient, and reproducible method to evaluate microvascular perfusion. Assessment of culprit-MBF after PCI in STEMI patients adds independent short-term prognostic information over qualitative analysis.It has the potential to be a valuable tool for risk stratification and clinical follow-up.

Objective To observe the difference in the expression of micro-ribonucleic acid(miRNA)in the colon tissue of irritable bowel syndrome-diarrhea(IBS-D)rats and rats treated with Jianpi Mixture,and predict The miRNA and corresponding genes involved in the treatment of IBS-D with Jianpi Mixture,providing a basis for finding potential therapeutic targets for IBS-D.Methods The rats were randomly divided into a blank group,a model group and a traditional Chinese medicine group,with 8 rats in each group.Both the model group and the Chinese medicine group used acute and chronic stimulation + senna leaf gavage to make the IBS-D model.The Chinese medicine group was gavaged with Jianpi Mixture after model building for 14 days.General condition,body weight and Bristol score were observed and recorded.Hematoxylin-eosin(HE)staining was used to observe the histopathological changes of colon in each group of rats.Transcriptome sequencing of rat colon tissue in each group to screen and map differentially expressed miRNAs.Perform GO(Gene oncology)functional enrichment analysis and KEGG(Kyoto Encyclopedia of Genes and Genomes)pathway enrichment analysis on the target genes corresponding to the screened common miRNAs.Results Compared with the model group,the weight of the rats in the Chinese medicine group increased significantly(P<0.01),and the Bristol score of the feces decreased significantly(P<0.01).The pathological damage of the colon tissue of rats in the Chinese medicine group was significantly reduced.Compared with the blank group,there were 109 differentially expressed genes in the model group,of which 80 were up-regulated and 29 were down-regulated.Compared with the model group,there were 109 differentially expressed genes in the traditional Chinese medicine group,of which 19 were up-regulated and 90 were down-regulated.Mapping the genes of the two comparisons found that 74 miRNAs in the model group were increased and 7 were decreased.The changes of these miRNAs were all reversed after the intervention of traditional Chinese medicine.The GO function enrichment analysis of target genes showed that Jianpi Mixture was mainly involved in synaptic vesicle positioning and transport,cytoplasmic transport,negative regulation of growth and development,and sugar transport after acting on rats.KEGG pathway enrichment analysis showed that MAPK,Wnt,Hippo,TNF,oxygen toxin,cAMP and other pathways were enriched.Conclusion After the intervention of Jianpi Mixture,IBS-D-related miRNA expression profiles have changed significantly;Jianpi Mixture may play a protective role in the treatment of IBS-D by regulating the MAPK signaling pathway and Wnt signaling pathway.Screening the core genes and predicting the miRNAs interacting with them provide a theoretical basis for the study of the pathogenesis of IBS-D and the therapeutic targets of Jianpi Mixture.

OBJECTIVE To study the clinical characteristics of leflunomide-induced int erstitial pneumonia （Lef-IP），and to provide reference for its clinical diagnosis ，treatment and prevention. METHODS Lef-IP cases published in domestic and foreign journals from January 2004 to June 2021 were collected. Relevant information of patients were extracted and analyzed retrospectively， including basic characteristics ，clinical manifestations ，imaging manifestations ，laboratory examinations ， histopathological examinations ，treatment and outcome. RESULTS A total of 54 Lef-IP patients from case reports of 24 publications were included ，with a median age of 61 years（9-83 years）. Pulmonary symptoms appeared from 3.3 weeks to 132.9 weeks（median time of 14.5 weeks）. Patients with a loading dose of leflunomide have a shorter median time to pulmonary symptoms appearing （7.5 weeks）. The main clinical manifestations were dyspnea （85.2％），cough（57.4％），fever（53.7％）. CT imaging examination showed 19 cases with ground-glass shadow in both lungs ，and 29 cases showed interstitial infiltration in both lungs on chest radiograph；blood gas analysis showed hypoxemia and hypocapnia ；the levels of C-reactive protein and Krebs von Den lungen- 6 （KL-6）increased；histopathological examination mainly showed interstitial pneumonia （8 cases），including 3 cases of diffuse alveolar injury ，4 cases of lymphocytes in bronchoalveolar lavage fluid ，and 1 case of noncaseating granuloma. After discontinued leflunomide and symptomatic treatment （antibiotics，hormones，colecenamine，plasma exchange ），35 patients（64.8％）recovered or improved their lung symptoms. Twelve patients （22.2％）died，and patients with fever may had a higher mortality rate （34.5％， P＝0.02）. CONCLUSIONS The main clinical manifestations of Lef-IP are dyspnea ，cough and fever. Loading doses of leflunomide should be avoided at the beginning of treatment. When lef-IP occurs ，leflunomide is discontinued and corresponding treatment is given，and most of the patients ’pulmonary symptoms can return to normal or be improved.
