Objective To investigate the diagnostic value of color Doppler ultrasound of neck vessels combined with head and neck CT angiography (CTA) in detecting carotid artery stenosis among patients with stroke. Methods A total of 104 patients with stroke admitted to the hospital between January 2023 and November 2024 were enrolled. All patients underwent color Doppler ultrasound of neck vessels and head and neck CTA, with digital subtraction angiography (DSA) used as the gold standard. Receiver operating characteristic (ROC) curves were plotted to analyze the diagnostic performance of each modality alone and in combination for detecting carotid artery stenosis in patients with stroke. Results According to the DSA results, among the 104 patients, 7 were normal, while 47, 16, 25, and 9 cases showed mild, moderate, and severe stenosis and occlusion, respectively. Color Doppler ultrasound results showed 6 normal cases, and 45, 20, 23, and 10 cases of mild, moderate, and severe stenosis and occlusion, respectively. Using DSA as the gold standard, the sensitivity, specificity and kappa value for diagnosing carotid artery stenosis were 98.97%, 85.71% and 0.848, respectively. Head and neck CTA results showed 5 normal cases, and 47, 19, 22, and 9 cases of mild, moderate, and severe stenosis and occlusion, respectively. The sensitivity, specificity and kappa value of head and neck CTA for diagnosing carotid artery stenosis were 100.00%, 71.43% and 0.823, respectively. The combined examination results showed that among the 104 patients, there were 7 normal cases, and 46, 18, 24, and 9 cases of mild, moderate, and severe stenosis and occlusion, respectively. The sensitivity, specificity and kappa value of the combined diagnosis were 100.00%, 100.00% and 1.000, respectively. In the ROC analysis, the areas under the curves of color Doppler ultrasound, head and neck CTA, and the combined method were 0.968, 0.934, and 1.000, respectively, with no significant difference among the three ROC curves (Z = 1.017, 0.994, 1.527, respectively, P = 0.309, 0.320, 0.167, respectively). Conclusion Color Doppler ultrasound of neck vessels combined with head and neck CTA shows good consistency with DSA in diagnosing carotid artery stenosis and its severity among patients with stroke. This combined method demonstrates high diagnostic performance, making it worthy of clinical application and promotion.

OBJECTIVE: To investigate the effects of Huayu Tongluo (transforming stasis and unblocking collaterals) moxibustion on cognitive function and insulin resistance in patients with type 2 diabetes mellitus (T2DM) and cognitive decline. METHODS: Ninety patients with T2DM and cognitive decline were randomly divided into a moxibustion group (n=45, 3 cases dropped out, 2 cases were eliminated) and a waiting moxibustion group (n=45, 2 cases dropped out). Both groups received routine hypoglycemic treatment for 12 weeks. The moxibustion group additionally received Huayu Tongluo moxibustion at Baihui (GV20), Shenting (GV24), and Dazhui (GV14). Pressing moxibustion was applied to Baihui (GV20) for 20 min, while suspended moxibustion was applied to Shenting (GV24) and Dazhui (GV14) for 20 min each. Treatments of moxibustion were administered every other day (three times per week) for 12 weeks. All patients were followed up for 12 weeks, during which their original hypoglycemic medication regimen was maintained. Before treatment, after 12 weeks of treatment, and at the 12-week follow-up, the scores of Montreal cognitive assessment (MoCA), mini-mental state examination (MMSE), Addenbrooke's cognitive examination Ⅲ (ACE-Ⅲ), symbol digit modalities test (SDMT), and Athens insomnia scale (AIS) and the insulin resistance index (HOMA-IR) were observed in the two groups. RESULTS: Compared with before treatment, the MoCA scores, MMSE scores, ACE-Ⅲ subscale scores (attention, memory, language fluency, language, visuospatial ability) and total scores, and SDMT scores were increased (P<0.01), while the AIS scores were decreased (P<0.05) in the moxibustion group after treatment and at follow-up. Compared with before treatment, the MMSE score, ACE-Ⅲ subscale scores (memory, attention) and total score after treatment, as well as the ACE-Ⅲ subscale scores (language, memory, attention) and total score, and SDMT score at follow-up were increased (P<0.05, P<0.01) in the waiting moxibustion group. Compared with before treatment, HOMA-IR was decreased in both groups after treatment and at follow-up (P<0.01). At follow-up, ACE-Ⅲ subscale scores (attention, memory), and the total score in the moxibustion group were lower than those after treatment (P<0.05, P<0.01), and the ACE-Ⅲ language subscale score, total ACE-Ⅲ score, and SDMT score in the waiting moxibustion group were higher than those after treatment (P<0.01, P<0.05). After treatment and at follow-up, compared with the waiting moxibustion group, the moxibustion group had higher MoCA scores, MMSE scores, SDMT scores, ACE-Ⅲ subscale scores (attention, memory, language fluency) and total scores (P<0.05, P<0.01), and lower HOMA-IR (P<0.05). CONCLUSION Huayu Tongluo moxibustion can effectively improve cognitive function in patients with T2DM and cognitive decline. This improvement may be associated with the reduction in insulin resistance.

Objective:To analyze the association between inflammation-related dietary patterns and the risk for cognitive impairment in older adults aged ≥65 years in longevity areas in China by using reduced rank regression (RRR) analysis.Methods:This study used cross-sectional data from the 2021 Healthy Aging and Biomarkers Cohort Study, including the information about study participants' demographic characteristics, lifestyles, daily life activities, and disease histories. Dietary intake was obtained by using a simplified food frequency questionnaire. Cognitive impairment was evaluated based on the Mini-Mental State Examination Scale combined with years of education. Fasting venous blood samples were collected to detect inflammatory markers, especially high-sensitivity C-reactive protein (hs-CRP) and the platelet-to-lymphocyte ratio (PLR). RRR analysis was used to obtain inflammation-related dietary patterns using hs-CRP and PLR as response variables. Multivariate logistic regression model was used to analyze the association between dietary pattern score and the risk for cognitive impairment. Restricted cubic spline was used to explore the dose response relationship, and mediation analysis was used to quantify the mediating effects of hs-CRP and PLR.Results:Two dietary patterns were identified with RRR. The primary pattern was characterized by higher intakes of flour, red meat, and dairy products, and lower intake of fresh vegetables, explaining 6.84% of the variance in food intake and 0.50% of the variance in inflammatory markers. Compared with the T1 group, the T3 group had significantly higher risk for cognitive impairment ( OR=1.242, 95% CI: 1.034-1.491). Each one standard deviation increase in the dietary pattern score was associated with an 8.7% increase in the risk for cognitive impairment ( OR=1.087, 95% CI: 1.008-1.172), with a significant linear trend (overall-model P<0.001, non-linear P=0.295). Mediation analysis indicated that hs-CRP mediated 6.2% of the association between the dietary pattern and the risk for cognitive impairment. Conclusion:The inflammation- related dietary pattern characterized by higher consumption of flour, red meat, and dairy products and lower consumption of fresh vegetables is associated with an increased risk for cognitive impairment in older adults, and hs-CRP partially mediates this association.

Inflammatory breast cancer(IBC)is a rare but highly aggressive subtype of breast cancer characterized by rapid clinical progression and poor prognosis.Although it accounts for only 2%-4%of all breast cancer cases,it is responsible for 8%-10%of breast cancer-related mortality.The etiology of IBC is multifactorial,involving genetic,hormonal,environmental,and socioeconomic factors.Pathologically,IBC is marked by the presence of dermal lymphatic tumor emboli,and molecular subtypes are predominantly HER2-positive and triple-negative,indicating high tumor invasiveness.Diagnosis relies on characteristic clinical manifestations and histopathological confirmation,while imaging techniques such as MRI and PET/CT play important roles in evaluating disease extent and metastasis.Given that IBC is often diagnosed at a locally advanced or metastatic stage,there is currently no specific treatment protocol.Instead,management generally follows the treatment paradigm of non-IBC,emphasizing systemic therapy within a multidisciplinary framework.HER2-positive IBC benefits from chemotherapy combined with dual-targeted anti-HER2 therapy;triple-negative IBC may respond to immune checkpoint inhibitors;and CDK4/6 inhibitors show potential efficacy in hormone receptor-positive subtypes.Despite advancements,the prognosis remains poor,with a high risk of early recurrence and distant metastasis.Prognostic factors include lymph node involvement,molecular subtype,and response to neoadjuvant therapy.As research into the tumor microenvironment and molecular mechanisms deepens,targeted and individualized therapies hold promise for improving outcomes.This review summarizes the epidemiology,pathology,diagnostic criteria,treatment strategies,and prognostic factors of IBC,aiming to inform clinical practice and future research.

Antibody-drug conjugates (ADCs) represent a promising class of targeted cancer therapeutics that combine the specificity of monoclonal antibodies with the potency of cytotoxic payloads. Despite their therapeutic potential, the use of ADCs faces significant challenges, including off/on-target toxicity and resistance development. This review examines the current landscape of ADC development, focusing on the critical aspects of target selection and antibody engineering. We discuss strategies to increase ADC efficacy and safety, including multitarget approaches, pH-dependent antibodies, and masked peptide technologies. The importance of comprehensive antigen expression profiling in both tumor and normal tissues is emphasized, highlighting the role of advanced technologies, such as single-cell sequencing and artificial intelligence, in optimizing target selection. Furthermore, we explore combination therapies and innovations in linker‒payload chemistry, which may provide approaches for expanding the therapeutic window of ADCs. These advances pave the way for the development of more precise and effective cancer treatments, potentially extending ADC applications beyond oncology.

Objective To explore the predictive value of combined detection of serum CXC chemokine lig-and 12(CXCL12),caspase-cleaved cytokeratin 18(CCCK-18)and matrix metalloproteinase-9(MMP-9)for short-term poor prognosis in patients with acute hemorrhagic stroke.Methods A total of 138 patients with a-cute hemorrhagic stroke admitted to a hospital from October 2021 to March 2023 were selected as the study objects.Serum CXCL12,CCCK-18 and MMP-9 levels were detected after admission and before treatment.Pa-tients were followed up for 6 months after treatment and were divided into good prognosis group and poor prognosis group according to the modified Rankin scale score.Clinical data and serum CXCL12,CCCK-18 and MMP-9 levels of the two groups were compared to analyze the factors affecting the short-term poor prognosis of patients with acute hemorrhagic stroke.Receiver operating characteristic(ROC)curve was drawn to evalu-ate the predictive value of single and combined detection of serum CXCL12,CCCK-18 and MMP-9 in patients with acute hemorrhagic stroke.Results Among 138 patients,there were 52 cases in the poor prognosis group and 86 cases in the good prognosis group,and the poor prognosis rate was 37.68%.Serum CXCL12,CCCK-18 and MMP-9 levels,age,blood loss at admission,National Institutes of Health Stroke Scale(NIHSS)score at admission,systolic blood pressure and diastolic blood pressure at admission in the poor prognosis group were higher than those in the good prognosis group.The score of Glasgow Coma Scale(GCS)at admission was lower than that of good prognosis group,and the difference was statistically significant(P<0.05).Multivari-ate Logistic regression analysis showed that high level of serum CXCL12,high level of CCCK-18,high level of MMP-9,older age,large amount of blood loss upon admission,high NIHSS score and high systolic blood pres-sure were all risk factors for short-term poor prognosis of acute hemorrhagic stroke(P<0.05).High GCS score on admission was a protective factor(P<0.05).ROC curve analysis showed that the area under the combined prediction curve of serum CXCL12,CCCK-18 and MMP-9 was higher than that of the single and pairwise combined prediction of each index(P<0.05).Conclusion The combined detection of serum CX-CL12,CCCK-18 and MMP-9 has a good value in predicting the short-term poor prognosis of patients with a-cute hemorrhagic stroke.

Background and Aims:Centrally located breast cancer(CLBC),due to its proximity to the nipple-areolar complex,has long been treated primarily with mastectomy,while the oncologic safety of breast-conserving surgery(BCS)remains controversial.This study,based on a large-scale database combined with a real-world cohort,compared the survival outcomes of BCS and mastectomy to evaluate the feasibility and oncologic safety of BCS in CLBC patients.Methods:Data of 10 325 female CLBC patients diagnosed between 2010 and 2015 were extracted from the SEER database,including 5 601 patients who underwent BCS and 4 724 who underwent mastectomy.Propensity score matching(PSM)yielded 1 951 matched pairs,and disease-specific survival(DSS)and overall survival(OS)were compared between groups.Cox regression analyses were performed to identify prognostic factors,and subgroup analyses were conducted.Additionally,an independent validation cohort from Xiangya Hospital,Central South University(2015-2016)included 221 BCS and 636 mastectomy patients,with OS and progression-free survival(PFS)assessed.Results:After PSM,baseline characteristics between groups were well balanced.Kaplan-Meier analysis demonstrated no significant differences in DSS or OS between BCS and mastectomy,and 5-,7-,and 10-year OS rates were comparable(all P＞0.05).Subgroup analyses revealed equivalent outcomes for BCS and mastectomy in patients with T1/T2 disease,different HER2 statuses,and those receiving chemotherapy,while in patients receiving radiotherapy,BCS showed significantly better DSS and OS than mastectomy(both P＜0.05).Multivariate Cox regression identified T,N,and M stage,histologic grade,molecular subtype,ER/PR status,and chemotherapy as independent prognostic factors(all P＜0.05),whereas surgical type was not(P＞0.05).The validation cohort confirmed the SEER findings,with no significant differences in OS or PFS between the two groups(both P＞0.05).Conclusions:BCS provides DSS and OS comparable to mastectomy in CLBC patients and may confer additional survival benefits when combined with radiotherapy.These findings suggest that CLBC should not be considered a contraindication to BCS,supporting BCS as a feasible and safe surgical strategy that offers valuable evidence for individualized clinical decision-making and may help improve patients' quality of life.

Objective:To investigate the related factors of hyperuricemia(HUA)in adolescents with bipolar disorder.Methods:Fifty-nine adolescent patients with bipolar disorder and 60 normal controls were select-ed.General demographic and clinical data were collected.Serum uric acid(UA),triglyceride(TG),total cholesterol(TC),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C),fasting blood glucose(FPG),fructosamine(FA)and other physiological indices were detected.The Hamilton Depression Scale 17(HAMD-17)and Bech-Rafaelsen Mania Scale(BRMS)were used to evaluate the emotional symptoms of the patients.Results:The detection rate of HUA was higher in the adolescent patients with bipolar disorder than in the normal control group(30.5％vs.18.3％,P＜0.05),and was higher in manic episode than in depressive episode(48.2％vs.20.8％,P＜0.05).Unconditioned logistic regression analysis showed that high level of TG and high BMI were risk factors for hyperuricemia in adolescents with bipolar disorder(OR=2.51,1.34).Conclusion:This study shows that adolescents with bipolar disorder may have a higher risk of HUA than normal controls,and its oc-currence is associated with high TG level and BMI.
