Xiang thinking is a cognitive approach that reflects the relationships between phenomena and their underlying principles by analyzing their external manifestations through methods such as analogy， reasoning， deduction， and symbolism. This article applied xiang thinking to analyze the etiology and pathogenesis of "wind， fire， phlegm， and blood stasis" in stroke， thereby exploring its impact on the principles of syndrome differentiation and treatment of this condition. Meanwhile， the article traced the construction process of xiang thinking， and interpreted the concept of "toxin pathogen" in traditional Chinese medicine from four perspectives， state， attribute， origin， and law. Furthermore， the relationship between the process of constructing xiang thinking and the origin of etiology， identification methods， pathogenesis evolution， and treatment strategies for stroke with syndrome of combined blood stasis and toxin was explored， so as to provide insights into research on the etiology and pathogenesis of stroke， as well as clinical diagnosis and treatment approaches.

Objective To investigate the efficacy and safety of the Corheart 6 left ventricular assist system in patients with end-stage heart failure. Methods A retrospective study was conducted on patients with end-stage heart failure who were treated with Corheart 6 left ventricular assist system from March 2022 to June 2024 in 4 hospitals in Jiangsu Province. The efficacy of the device was evaluated by comparing changes in clinical indicators at preoperative, discharge, 3-month postoperative, and 6-month postoperative timepoints, including the New York Heart Association (NYHA) functional classification, left ventricular ejection fraction (LVEF), and left ventricular end-diastolic diameter (LVEDD). The safety of the device was assessed by analyzing the intraoperative position and orientation of the blood pump inlet cannula, as well as the incidence of adverse events. Results In this study, 39 patients were collected, including 34 males and 5 females with a mean age of (56.4±12.5) years, ranging from 20 to 75 years. There was no operative death. There was no death in postoperative 3 months with a survival rate of 100.0%. There were 3 deaths in 6 months postoperatively, with a survival rate of 92.3%. All patients had a preoperative NYHA cardiac function classification of class Ⅳ. The NYHA cardiac function class of the patients improved (P<0.05) at discharge, 3 and 6 months after surgery when compared to the preoperative period. LVEF was significantly higher at 3 months after surgery than that during the preoperative period (P<0.05). LVEDD was significantly smaller at discharge, 3 and 6 months after surgery than that during the preoperative period (P<0.05). The safety evaluation's findings demonstrated that all 39 patients' intraoperative blood pump inlet tubes were oriented correctly, the artificial blood vessel suture sites were appropriate, there were no instances of device malfunction or pump thrombosis, or instances of bleeding or hemolysis, and the rate of the remaining adverse events was low. Conclusion With a low rate of adverse events and an excellent safety profile, the Corheart 6 left ventricular assist system can efficiently enhance cardiac function in patients with end-stage heart failure. It also has considerable clinical uses.

Aim To explore the protective effect of an-thocyanin B2(PCB2)on hydrogen peroxide(H2O2)induced oxidative damage and apoptosis in human oli-godendrocytes(MO3.13)and the underlying mecha-nism.Methods The optimal concentration of H2O2 and PCB2 for action was screened,and divided into normal group,PCB2 group(100 mg·L-1 PCB2 treat-ment for 24 hours),H2 O2 model group(500 μmol·L-1 H2O2 treatment for 24 hours),and H2O2+PCB2 group(500 μmol·L-1 H2O2 and 100 mg·L-1 PCB2 co-treated for 24 hours).FRAP method was used to detect the antioxidant capacity of PCB2;CCK-8 meth-od was used to detect the survival rate of cells in each group,while LDH method was used to assess cytotoxic-ity.Microenzyme-linked immunosorbent assay and ELISA were used to examine the levels of LDH,NO,H2O2,as well as the activities of CAT and SOD in each group of cells.Immunofluorescence and Western blot were used to detect the protein expression levels of NRF2,xCT,HO-1,ferritin,and GPX4 in each group of cells.FerroOrange fluorescent probe was used to de-tect the intracellular content of ferrous ions(Fe2+).Results H2O2 could induce MO3.13 oxidative dam-age and lead to cell ferroptosis,while PCB2 could alle-viate MO3.13 oxidative damage and ferroptosis.Com-pared with the H2O2 model group,PCB2 intervention could significantly increase LDH content in MO3.13,reduce NO and H2O2 content,and improve SOD and CAT activity,and up-regulate the protein expression levels of NRF2,xCT,HO-1,ferritin,and GPX4.Conclusion PCB2 can enhance cellular antioxidant capacity and alleviate H2O2 induced MO3.13 oxidative damage through the NRF2/HO-1/xCT/GPX4 axis.

Aim To explore the mechanism and mate-rial basis of Shenkang injection(SKI)in the treatment of renal fibrosis(RF)by bioinformatics and in vitro experiments.Methods The differentially expressed genes of RF were screened by GEO database.With the help of CMAP database,based on the similarity princi-ple of gene expression profile,the drugs that regulated RF were repositioned,and then the components of SKI potential treatment RF were screened by molecular fin-gerprint similarity analysis.At the same time,the core targets and pathways of SKI regulating RF were predic-ted based on network pharmacology.Finally,it was verified by molecular docking and cell experiments.Results Based on the GEO database,two RF-related data sets were screened,and CMAP was relocated to three common RF therapeutic drugs(saracatinib,da-satinib,pp-2).Molecular fingerprint similarity analysis showed that RF therapeutic drugs had high structural similarity with five SKI components such as salvianolic acid B and hydroxysafflor yellow A.Molecular docking results showed that salvianolic acid B,hydroxysafflor yellow A and other components had good binding abili-ty with MMP1 and MMP13,which were the core targets of SKI-regulated potential treatment of RF.Network pharmacology analysis suggested that the core targets of SKI were mainly enriched in signaling pathways such as Relaxin and AGE-RAGE.Cell experiments showed that SKI could significantly reduce the mRNA expres-sion levels of AGER,NFKB1,COL1A1,SERPINE1,VEGFC in AGE-RAGE signaling pathway and MMP1 and MMP13 in Relaxin signaling pathway in RF model cells,and significantly increase the mRNA expression level of RXFP1.Conclusions SKI can play a role in the treatment of RF by regulating Relaxin and AGE-RAGE signaling pathways,and its material basis may be salvianolic acid B,hydroxysafflor yellow A and other components.

Coronary artery fistula(CAF)is defined as the direct connection between coronary artery and cardiac cavity,great vessel or other vascular structures.Most CAF are congenital and often present as persistent murmur in asymptomatic children.Although abnormal shunt of most coronary fistulas has little effect on hemodynamics,some larger fistulas can also lead to a series of complications,such as congestive heart failure.Therefore,closed CAF has been recommended to treat or prevent myocardial ischemia,congestive heart failure,endarteritis,arrhythmia,thromboembolism,aneurysm dilatation and rupture and other complications.CAF is a rare congenital heart disease,and bilateral CAF originating from two coronary arteries is even rarer.At present,there are rare systematic reports on bilateral CAF.Therefore,a case of huge bilateral CAF at the same site was reported,and systematically,this kind of case was summarized,so as to improve the clinical attention of diagnosis and treatment of this kind of CAF.Nowadays,some new interventional devices and technologies are emerging with the continuous progress of cardiovascular interventional technology,making the treatment more accurate,safe and effective.At the same time,there is also a clearer understanding of the indications and operating standards for interventional treatment,which is more operable and predictable during the treatment process.Therefore,interventional treatment of CAF may partially replace surgical treatment as the preferred treatment method.

Objective To analyze the incidence of major adverse cardiovascular events(MACE)in 45 patients who unexpectedly interrupted dual antiplatelet therapy(DAPT)within one month after percutaneous coronary intervention(PCI).Methods A total of 4 876 patients who successfully underwent PCI and implanted one or more stents(excluding acute ST segment elevation myocardial infarction,drug coated balloon or non-drug coated ballooon only,and oral anticoagulants)between January 1,2017 and December 31,2022 were selected as the study subjects.A total of 45 patients with unexpected interruption of DAPT within one month after PCI were analyzed,and their clinical outcomes were followed up.Results Among the 45 patients,there were 29 males and 16 females,aged 48-80(61.7+15.3)years.The reasons for interrupting DAPT include:35 cases of bleeding;3 cases of malignant tumor surgery(including 2 bleeding patients);5 cases of trauma;2 cases of hematological diseases;2 cases of self-interruption of DAPT.6 patients who received low-molecular-weight heparin replacement therapy during the discontinuation period did not experience stent thrombosis or other MACE.Among the 39 patients without antithrombotic replacement therapy,5 developed stent thrombosis and acute myocardial infarction(5/45,11.1％).Except for 1 patient who voluntarily stopped DAPT 2 weeks after PCI,the remaining 4 cases were those who with concurrent bleeding within 2 weeks after PCI.DAPT was stopped for more than 10 days,and stent thrombosis occurred on the 10th,11th,11th,and 13th days after DAPT was stopped.Among the 4 patients,2 patients developed acute left heart failure and 1 patient died.Another case died due to brainstem hemorrhage.Conclusions Premature interruption of DAPT after PCI has a high potential risk.Patients who stop taking medication earlier,for a longer duration,and without replacement therapy have a higher risk.

Objective:To compare the efficacy and clinical value of high-throughput sequencing(HTS)and Sanger sequencing in detecting ABL kinase domain mutations in patients with chronic myeloid leukemia(CML).Methods:A total of 198 samples of 147 CML patients from July 2017 to March 2021 in Henan Cancer Hospital were collected and underwent high-throughput sequencing and Sanger sequencing to detect the mutations in ABL kinase domain,and the relevant clinical data were collected for comparative analysis.Results:The proportion of total mutations and ≥ 2 mutations detected by high-throughput sequencing were significantly higher than those detected by Sanger sequencing(P=0.01;P=0.046).≥ 2 mutations were detected in 22 cases,of which 5 cases(22.7％)had compound mutations.High-throughput sequencing can detect low level mutations that cannot be detected by Sanger sequencing.In 198 samples,25(12.6％)were low level mutations,33(16.7％)were high level mutations and 10(5.1％)were mixed high and low level mutations.In the analysis of related clinical factors,the total mutation rate and the low level mutation rate in the optimal period,failure period and warning period were gradually increased(total mutation rate,P=0.016;low level mutation rate,P=0.005).The mutation rate of the samples with additional chromosomal abnormalities was also significantly increased(P=0.009).The mutation rate of patients who received first-and second-line treatment was significantly lower than that of patients who received third-or higher-line treatment(P=0.006).Analysis based on variant allele frequency(VAF)of the mutation site was helpful to visually evaluate the clonal evolution status of TKI-resistance CML cells.Conclusion:High-throughput sequencing is more sensitive and accurate than Sanger sequencing in mutation detection,which is helpful to accurately and visually evaluate TKI treatment response and optimize treatment strategy for CML.

Objective:To analyze thalassemia genotypes and distribution of children in Wuzhou Guangxi,and evaluate the diagnostic value of HbA2 in children's thalassemia screening,so as to provide scientific evidence for the prevention and control strategies of thalassemia.Methods:Four hundred and fifty-eight children suspected with thalassemia in Wuzhou were enrolled from March 2017 to June 2022.The level of HbA2 was detected using Bio-Rad VARIANT Ⅱ Hb analysis system.The deletion of α-thalassemia was measured with gap-PCR assay,and the point mutation of α-and β-thalassemia was tested with DNA reverse dot blot hybridization assay.The receiver operating characteristic(ROC)curve was used to analyze the diagnostic value of HbA2 for children's thalassemia.Results:A total of 304 thalassemia carriers were detected in 458 children,accounting for 66.38％.One hundred and seventy-five cases were defined to be α-thalassemia,with the main type of--SEA/αα(54.86％).Thirty-six cases were defined to be intermediate α-thalassemia,with the main type of-α3.7/--SEA(9.72％).In 108 cases with β-thalassemia,βCD41-42/βN was the main type,accounting for 49.07％,followed by βIVS-Ⅱ-654/βN(14.81％).Seven cases were moderate/severe β-thalassemia(predominantly β-28/β-28 and βCD41-42/βCD17)Twenty-one genotypes of α-and β-thalassemia were found in the children.There was significant difference of HbA2 level between the children with different types of thalassemia and healthy controls(all P＜0.001).ROC curve analysis showed that the sensitivities of HbA2 for α-thalassemia,β-thalassemia and αβ-thalassemia were 74.3％,82.4％and 85.7％,with the optimal cut-off values of 2.60％,3.60％and 3.70％,respectively,the specificities were 64.3％,96.1％and 96.8％,and the area under the curve were 0.690,0.887 and 0.916,respectively.Conclusion:The thalassemia genotypes of children in Wuzhou are diverse.It is necessary to further strengthen the prevention and control measure of thalassemia to reduce birth defects and improve birth quality.

Objective:To explore the therapeutic efficacy and prognostic factors of induction therapy for secondary central nervous system lymphoma(SCNSL).Methods:Clinical data of patients diagnosed with SCNSL from 2010 to 2021 at Guangdong Provincial People's Hospital were retrospectively collected.A retrospective cohort study was performed on all and grouped patients to analyze the efficacy and survival.Multivariate logistic regression analysis was used to explore the adverse prognostic factors.Results:Thirty-seven diffuse large B-cell lymphoma patients with secondary central involvement were included in the research.Their 2-year overall survival(OS)rate was 46.01％and median survival time was 18.1 months.The 2-year OS rates of HD-MTX group and TMZ group were 34.3％and 61％,median survival time were 8.7 and 38.3 months,and median progression-free survival time were 8.1 and 47 months,respectively.Multivariate logistic regression analysis showed that age,sex,IPI,Ann Arbor stage were correlated with patient survival time.The median survival time of patients with CD79B,KMT2D,CXCR4.ERBB2,TBL1XR1,BTG2,MYC,MYD88,and PIM1 mutations was 8.2 months,which was lower than the overall level.Conclusion:HD-MTX combined with TMZ as the first-line strategy may improve patient prognosis,and early application of gene sequencing is beneficial for evaluating prognosis.
