In recent years, the incidence of liver metastasis from colorectal cancer has continued to rise, posing a significant threat to human health and life.Although traditional treat-ments such as surgery and chemotherapy have shown some efficacy in certain patients, options remain limited for those who are not surgical candidates or are resistant to chemotherapy.Yttrium-90 microsphere selective internal radiation therapy, as an innovative local treatment, has fully demons-trated its effectiveness and safety in treating colorectal cancer liver metastasis patients. The authors review the research background, mechanisms, and principles of yttrium-90 microsphere selective internal radiation therapy in the field of colorectal cancer liver metastasis, and to explore its applica-tion progress in clinical practice, aiming to provide clinical doctors with more comprehensive and detailed reference information, with the goal of improving treatment outcomes and quality of life for colorectal cancer liver metastasis patients.

Objective To evaluate the efficacy and safety of a novel intravascular lithotripsy(IVL)balloon—Vesscrack shockwave balloon—for vascular preparation before stent implantation in patients with severe coronary artery calcification(CAC).Methods This was a prospective,single-arm,multicenter study conducted in China from June 2022 to October 2022.Patients with severe CAC were treated with the Vesscrack shockwave balloon for lesion preparation,followed by drug-eluting stent(DES)implantation.Of these,33 patients underwent optical coherence tomography(OCT).The primary endpoint was procedural success,defined as successful stent implantation with residual stenosis≤30％and the absence of in-hospital major adverse events,including cardiac death,target vessel-related myocardial infarction,or target lesion revascularization.Results A total of 170 patients[mean age:(65.9±7.9)years,116 males]were enrolled.After treatment with IVL and DES,the minimum lumen diameter increased significantly compared to baseline[(2.34±0.40)mm vs.(0.95±0.33)mm,P＜0.001],the degree of stenosis was significantly reduced[(13.24±6.60)％vs.(65.18±10.59)％,P＜0.001].Procedural success was achieved in 100％of cases,and device success was 98.8％.The 30-day patient-related cardiovascular clinical composite endpoint(POCE)rate was 0.0,with no target lesion failure,no confirmed or potential thrombotic events were observed.The shockwave energy generator demonstrated excellent stability and ease of use.Among the 33 patients assessed with OCT,after IVL intervention,the maximum calcified area of the lumen[(3.51±1.51)mm2 vs.(2.85±1.80)mm2,P＜0.001],and the minimum lumen area within the target lesion[(3.08±1.04)mm2 vs.(2.02±0.75)mm2,P＜0.001],and after DES intervention,the luminal area of the largest calcified site[(6.59±1.64)mm2 vs.(2.85±1.80)mm2,P＜0.001]and the minimum luminal area within the target lesion[(6.19±1.45)mm2 vs.(2.02±0.75)mm2,P＜0.001]were significantly increased,and the differences were statistically significant.Conclusions The Vesscrack shockwave balloon is effective and safe for vascular preparation in patients with severe CAC prior to stent implantation.It achieves significant calcified plaque modification,high procedural success rates,and minimal complications.

Aim To investigate the protective effects of Tilianin on lipopolysaccharide(LPS)-induced septice-mia-induced myocardial injury in rats and to explore the related mechanisms.Methods Animals were ran-domly grouped and a rat septicemia-induced myocardial injury model was constructed.Echocardiography was used to assess the cardiac function of rats,left ventricu-lar internal diameter at end-diastole(LVIDd)and left ventricular internal diameter at end-systole(LVIDs)were measured,and left ventricular ejection fraction(LVEF)and left ventricular fractional shortening(LVFS)were calculated;the kits were used to detect the serum activity of the relevant cardiac enzymes and the level of inflammatory factors;HE staining was used to observe the morphological changes of myocardium;immunofluorescence staining of cardiac tissues was used to detect the nuclear translocation of NF-κB p65;Western blot was used to detect the expression of TLR4,MyD88,p-NF-κB p65,and NLRP3 proteins in cardiac tissues.Results Compared with the model group,each administration group differently upregulated LVEF,LVFS,and LVIDs,and improved the coordina-tion of LV wall fluctuations in the model group of rats;cardiac enzymes LDH and CK-MB levels increased,and levels of inflammatory factors TNF-α,IL-6,and IL-1 β were reduced,exerting cardioprotective effects;HE staining showed that myocardial tissue cell gap was re-duced,myocardial fiber breakage was reduced,cardio-myocyte arrangement tended to be normal,and inflam-matory cell infiltration was reduced;NF-κB p65 entry into the nucleus was reduced,and phosphorylated NF-κB p65(p-NF-κB p65)expression was reduced;and Western blot results showed that the expression of TLR4,MyD88,and NLRP3 proteins was reduced.Conclusions Tilianin pretreatment reduces serum my-ocardial enzymes and inflammatory factors and im-proves myocardial injury in rats with septicemia-in-duced myocardial injury,which may be related to the Tilianin anti-TLR4/NF-κB/NLRP3 inflammatory signa-ling pathway.

This study was aimed at establishing a sensitive and specific sandwich ELISA detection method for Brucella.We screened monoclonal capture antibodies and detection antibodies for Brucella detection,and optimized and determined the opti-mal antibody coating time and concentration,as well as the optimal blocking solution,blocking time,and yin-yang critical val-ue.The specificity of this method was verified by examination of other bacteria prone to cross-reacting with Brucella.The sen-sitivity of the method was verified by detection of a gradient dilution of inactivated Brucella.Moreover,the sandwich ELISA detection results were compared with test tube agglutination and qPCR results.The selected capture antibody was 4A12,and the selected detection antibody was 6C12.Experimental analysis indicated that the optimal coating concentration for the 4A12 capture antibody was 5 μg/mL,and the optimal dilution ratio for the 6C12 detection antibody was 1∶2000.The optimal coating conditions were overnight at 4℃,and blocking with 5％skim milk powder for 2 hours.The established double antibody sand-wich ELISA method reacted with only Brucella but not other bacteria,thus demonstrating the method's good specificity.Inac-tivated Brucella solution was still detectable after dilution to 1 × 105 CFU/mL,thus demonstrating the method's good sensitiv-ity.The intra-and inter batch coefficients of variation were both below 10％,thus indicating the method's good repeatability.Thus,this study successfully established a dual antibody sandwich ELISA method for Brucella detection,which has good spe-cificity and sensitivity,and might provide an effective approach for the precise diagnosis and effective prevention and control of brucellosis.

Family with sequence similarity 3 member A(FAM3A),a novel mitochondrial protein,plays a pivotal role in hepatic glucose and lipid metabolism by enhancing ATP synthesis and secretion and mod-ulating the ATP-P2 receptor-Akt signaling pathway.Dysregulation of FAM3A is closely associated with the pathogenesis of non-alcoholic fatty liver disease(NAFLD)and type 2 diabetes mellitus(T2DM).In this study,targeting FAM3A as a therapeutic candidate,we conducted virtual screening to identify 47 small-molecule compounds with potential binding activity.Surface plasmon resonance(SPR)analysis re-vealed three compounds exhibiting high binding affinity to FAM3 A.Further structural characterization of the FAM3A-compound complexes,combined with intermolecular interaction analysis,elucidated the binding mode of the lead compound Index 2(taxifolin)to FAM3A at atomic resolution.These findings provide critical insights into the molecular mechanisms underlying ligand-FAM3A interactions and deliver valuable chemical scaffolds for the development of therapeutics targeting NAFLD and T2DM.This work establishes a foundation for advancing drug discovery efforts focused on FAM3A-mediated metabolic disor-ders.

Objective:To evaluate the short-term efficacy of surgical treatment for severe pulmonary stenosis(PS) in infants and young children, and to clarify the impact of different surgical timings on the efficacy of PS treatment.Methods:A retrospective analysis was conducted on 24 infants and young children who underwent surgical treatment for severe PS at the General Hospital of Northern Theater Command, PLA, from January 1, 2020, to October 1, 2024. Among them, 13 were males and 11 were females. The average weight of the patients was(9.2±3.6) kg, the average gestational age was(39.3±1.7) weeks, and the average age was(15.0±13.5) months. Preoperative clinical symptoms and signs(e.g., cyanosis, shortness of breath), transpulmonary valve pressure gradient(TPVPG), right ventricular systolic pressure(RVSP), and Em/Am were recorded. The patients were divided into two groups based on surgical timing: the infant group(under 1 year old, n=12) and the toddler group(1-3 years old, n=12).Results:There were no deaths among all patients. The postoperative ICU stay was significantly longer in the infant group compared to the toddler group( P<0.05). Compared to preoperative values, surgical treatment significantly improved TPVPG, reduced RVSP, and enhanced right ventricular diastolic function, which stabilized by 3 months postoperatively( P<0.05). Intergroup comparisons revealed that the infant group had significantly lower TPVPG at 6 months postoperatively compared to the toddler group. Additionally, right ventricular diastolic function improved significantly in the infant group postoperatively, while no significant improvement was observed in the toddler group. Younger age and reduced right ventricular diastolic function were identified as major risk factors for prolonged mechanical ventilation(>24 hours). Conclusion:Surgical treatment for PS during infancy and early childhood is safe and effective. Comprehensive preoperative evaluation is crucial, and early surgical intervention is recommended for patients with impaired right ventricular function to improve prognosis.

Objective:To investigate the glymphatic system dysfunction and white matter microstructural damage in type 2 diabetic mellitus patients with diabetic peripheral neuropathy (DPN), and to identify the early diagnostic imaging biomarkers.Methods:Thirty-one DPN patients and 31 type 2 diabetes mellitus (T2DM) patients who attended the First People's Hospital of Yancheng from March 2022 to October 2023 were included. In addition, 40 healthy controls (HC) were recruited. All subjects underwent 3.0T MRI scan with diffusion tensor imaging and 3D-T1WI sequences, and the diffusion tensor imaging analysis along the perivascular space(DTI-ALPS) index, perivascular space volume fraction in white matter(PVSVF-WM) and peak width of skeletonized mean diffusivity (PSMD) were calculated. SPSS 26.0 software was used to perform one-way ANOVA, t-tests, and Chi-square tests to compare clinical data and imaging indicators among the three groups. Partial correlation analysis was used to explore the relationships between DTI-ALPS index, PVSVF-WM, PSMD and clinical indicators in DPN patients. Finally, receiver operating characteristic (ROC) curves were plotted to evaluate the diagnostic value of DTI-ALPS index, PVSVF-WM, and PSMD for DPN. Results:The DPN group(1.46±0.19)had considerably lower DTI-ALPS index than the T2DM group (1.59±0.14) and HC group (1.60±0.17) (both P<0.05, Bonferroni correction). The DPN group (1.44±0.11) had significantly higher PVSVF-WM than both the T2DM group (1.35±0.14) and HC group (1.26±0.13) (both P<0.05, Bonferroni correction). The DPN group (1.84±0.31) and the T2DM group (1.83±0.25) had higher PSMD than HC group (1.60±0.24) (both P<0.05, Bonferroni correction), but the difference between the DPN group and the T2DM group was not statistically significant ( P>0.05). The DTI-ALPS index in the DPN group were negatively correlated with PSMD ( r=-0.379, P=0.035). The DTI-ALPS index was negatively correlated with the Toronto clinical scoring system (TCSS) score ( r=-0.456, P=0.01), while PSMD was positively correlated with TCSS scores ( r=0.686, P<0.001) in DPN group. The ROC curves showed that the area under the curve (AUC) was 0.777 ( P<0.001) for the combined diagnosis of DPN with the DTI-ALPS index, PVSVF-WM and PSMD. Conclusion:DPN patients exhibit glymphatic system dysfunction and white matter microstructural damage. The DTI-ALPS index and PSMD can serve as objective markers for assessing DPN severity. The combination of glymphatic system function indicators and white matter microstructural damage markers has moderate diagnostic value for peripheral neuropathy in T2DM patients.

Objective To describe and analyze the current status,changing trend and influencing factors of the disease burden of cervical,endometrial and ovarian cancer in China from 1990 to 2021.Methods Data on incidence,mortality,disability-adjusted life year(DALY),and other indicators for cervical,endometrial and ovarian cancer were collected from the 2021 Global Burden of Disease database.Joinpoint regression models were used to analyze time trends,and age-period-cohort(APC)models assessed their impact on incidence and mortality.Spearman correlation analysis was performed to evaluate the relationship between the sociodemographic index(SDI)and the cancer indicators.Finally,the attributable risk factors for the disease burden were analyzed.Results From 1990 to 2021,age-standardized incidence rates of cervical and endometrial cancers in China significantly increased,while ovarian cancer showed no significant change.Age-standardized mortality,DALY,and years of life lost due to premature death(YLL)decreased significantly.The disease burden was heavier in middle-aged and older groups.APC model indicated an increase in cervical cancer incidence and a decrease in mortality over time.Furthermore,the incidence risks of cervical and endometrial cancers were elevated in successive birth cohorts,whereas a lower risk was observed for ovarian cancer.Correlation analysis showed significant associations between cancer incidence and mortality with SDI.Obesity has significantly contributed to the disease burden of common gynecologic cancers in China.Conclusion Mortality rates of cervical,endometrial and ovarian cancer have declined,while the incidence of cervical and endometrial cancers has significantly increased.The trends in incidence and mortality are influenced by age,period and cohort effects.Future efforts should focus on controlling risk factors like obesity to reduce the disease burden.
