Breast cancer is a malignant tumor that occurs in the glandular epithelium of the breast, and it is one of the most common tumors that seriously affect the physical and mental health of women. With the aggravation of population aging, the incidence of breast cancer in the elderly has increased year by year in recent years. Elderly patients with breast cancer often have a variety of underlying diseases, and their prognosis is usually related to many factors such as cancer staging, cancer classification, treatment status and health status, with a significant difference in survival rate among patients. Due to the unique clinical and pathological characteristics of elderly patients with breast cancer compared to young and middle-aged patients, there are many studies on the treatment of elderly breast cancer patients in the past, and there are few reviews on the influencing factors of prognosis in elderly patients. This paper reviews the research progress of influencing factors of prognosis in elderly patients with breast cancer from the aspects of clinicopathological factors, treatment options and prognosis factors, in order to provide a reference for clinical determination of treatment options for elderly patients with breast cancer in the future.

Objective To investigate the predictive value of dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)radiomics combined with Magee equation 3(ME3)for pathological response following neoadjuvant chemotherapy(NAC)in patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative(HR+/HER2-)breast cancer.Methods A ret-rospective analysis was performed on 325 breast cancer patients diagnosed with HR+/HER2-in two hospitals.Patients from the first hospital were randomly divided into training and internal validation sets at a ratio of 7∶3.Patients from the second hospital served as external validation set.The volume of interest(VOI)of breast cancer was delineated on DCE-MRI images.Then the rele-vant radiomics features were extracted and selected,and the Radiomics score(Radscore)was calculated.The statistically significant clinical and pathological features and Radscore were incorporated into a multivariate analysis.The combined radiomics-clinical model and nomogram were established,and the prediction performance was evaluated by using the receiver operating characteristic(ROC)curve,calibration curve,and decision curve analysis(DCA).Results In the training set,seven radiomics features were selected to construct the radiomics model.ME3 score emerged as the independent factor for pathological complete response(pCR)(P＜0.001).By integrating ME3 score and Radscore,a combined radiomics-clinical model was developed.This model demonstrated robust predictive accuracy,with area under the curve(AUC)of 0.88[95％confidence interval(CI)0.80-0.95],0.90(95％CI 0.82-0.98),and 0.82(95％CI 0.70-0.93)in the training,internal validation,and external validation sets,respectively.The nomogram construc-ted from the combined model exhibited excellent discrimination and calibration,with P-values of 0.455,0.312 and 0.062 in the train-ing,internal validation,and external validation sets.Conclusion DCE-MRI radiomics combined with ME3 can be used to predict the pathological response of NAC in HR+/HER2-breast cancer.

Age-related macular degeneration(AMD)is one of the leading causes of blindness in the elderly.Wet AMD(nAMD)accounts for more than 90％of AMD-related vision loss.Pathologically,nAMD is defined by choroidal neovascu-larization(CNV)and chronic retinal inflammation driven by oxidative stress,complement activation,pro-inflammatory cy-tokines,and overexpression of vascular endothelial growth factor(VEGF).Yet anti-VEGF monotherapy often falls short.The nuclear factor kappa-B(NF-κB)signaling cascade,acting through both canonical and non-canonical pathways,or-chestrates the expression of genes governing immunity,inflammation,apoptosis,and angiogenesis.In nAMD,oxidative stress and complement fragments ignite NF-κB,unleashing a repertoire of pro-inflammatory and pro-angiogenic mediators that fuel CNV.Pharmacologic or genetic suppression of NF-κB dampens both inflammation and neovascularization,attenua-ting experimental CNV.Thus,dissecting the molecular machinery of NF-κB signaling in nAMD may uncover novel combina-tion strategies that enhance therapeutic efficacy and curb anti-VEGF resistance.

Objective To explore the value of serum long non-coding RNA KCNQl opioid strand transcript 1(lncRNA KCNQ1OT1)and fibroblast growth factor 2(FGF2)in the evaluation of the condition and control level of pediatric bronchial asthma.Methods 96 children with bronchial asthma(Asthma group)and 76 healthy children(Control group)admitted to Yulin Hospital of Traditional Chinese Medicine from March 2021 to March 2023 were selected.According to the severity of bronchial asthma,the children were divided into a mild group(n=54)and a severe group(n=42).According to the disease control status after treatment,the children were divided into an asthma Control group(n=61)and an uncontrolled Asthma group(n=35).The serum levels of lncRNA KCNQ1OT1 and FGF2 were detected in each group.Multivariate Logistic regression analysis was performed to identify the factors affecting bronchial asthma disease control.The performance of lncRNA KCNQ1OT1 and FGF2 in predicting the control of bronchial asthma disease was evaluated using the receiver operating characteristic curve.Results The serum levels of lncRNA KCNQ1OT1(2.35±0.71)and FGF2(27.35±6.29 pg/ml)in the Asthma group were higher than those in the Control group(1.51±0.33,15.32±4.08 pg/ml),and the differences were statistically significant(t=9.527,14.437,all P<0.001).The serum levels of lncRNA KCNQ1OT1(2.59±0.35)and FGF2(28.65±1.03 pg/ml)in the severe group were higher than those in the mild group(2.16±0.41,26.34±1.24 pg/ml),and the differences were statistically significant(t=5.429,9.737,all P<0.001).The serum levels of lncRNA KCNQ1OT1(2.63±0.27)and FGF2(29.02±1.41 pg/ml)in the uncontrolled asthma group were higher than those in the controlled asthma group(2.19±0.35,26.39±1.52 pg/ml),and the differences were statistically significant(t=5.417,8.374,all P<0.001).High lncRNA KCNQ1OT1 and FGF2 levels were risk factors for uncontrolled disease in children with bronchial asthma(all P<0.05).The AUC of lncRNA KCNQ1OT1 and FGF2 combined to predict uncontrolled disease in children with bronchial asthma,which was higher than of lncRNA KCNQ1OT1 and FGF2 alone,and the differences were statistically significant(Z=3.250,2.096,all P<0.05).Conclusion Serum lncRNA KCNQ1OT1 and FGF2 are both elevated in children with bronchial asthma,which is related to the worsening of bronchial asthma and uncontrolled disease.Combining lncRNA KCNQ1OT1 and FGF2 can predict the level of bronchial asthma disease control.

Objective To explore the characteristics of incorrect opinions in re-examination cases,analyze the reasons,characteristics,and commonalities of different forensic opinions in the same injury case during re-examination,and provide references for similar case acceptance,forensic procedures,analysis and argumentation,and the application of relevant provisions.Methods A retrospective analysis was conducted on the re-examination cases of human injury degree accepted by the Forensic Judicial Appraisal Center of Guizhou Medical University and West China Forensic Medical Appraisal Center of Sichuan University from January 2020 to December 2024.Results Among the 81 collected re-examination cases of human injury degree,the injury types mainly included fractures,soft tissue injuries,tendon injuries,craniocerebral injuries,nerve injuries,joint injuries,and organ injuries.Of these,74 cases were entrusted by the public security system,and 72 cases used primary injuries as the basis for assessment.Seven cases had more than 3 appraisals and 74 cases had two appraisals,of which 53 cases had inconsistent opinions between the previous and current appraisals,including 29 cases with an upgraded injury grade and 24 cases with a downgraded injury grade.Conclusion When accepting re-examination cases,forensic experts need to choose relevant objective examination techniques in forensic clinical medicine,such as clinical imaging techniques,to determine whether imaging data serves as key evidence in the case,and seek assistance from experts in related fields when necessary.In the case acceptance stage,it is necessary to collect and review key assessment materials such as medical records,the first assessment opinion,and interrogation records.Forensic experts should also enhance their understanding of legal provisions,timing of assessment,their image-reading ability,and work to standardize the forensic assessment process.

Objective:To analyze the relationship between folate and thyroid antibody in early pregnancy and adverse pregnancy outcome in pregnant women with hypothyroidism during pregnancy.Methods:The data of 97 pregnant women with hypothyroidism from Jul. 2020 to Mar. 2023 in the Obstetrics Department of Liaocheng Second People’s Hospital were retrospectively analyzed. The levels of folate, thyroglobulin antibody (TGAb) and thyroid peroxidase antibody (TPOAb) were detected in the first trimester. According to whether adverse pregnancy outcome occurred in pregnant women with hypothyroidism during pregnancy, they were divided into occurrence group and non-occurrence group. The clinical data of the occurrence group and the non-occurrence group were compared. Logistic regression was used to analyze the influencing factors of adverse pregnancy outcomes in pregnant women with hypothyroidism during pregnancy, and receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of folic acid, TGAb, TPOAb and their combination on adverse pregnancy outcomes in pregnant women with hypothyroidism during pregnancy.Results:Among 97 pregnant women, the incidence of adverse pregnancy outcome was 14.43% (14/97) .The folate level in the occurrence group was lower than non-occurrence group ( P<0.05) , and the TGAb and TPOAb levels in the occurrence group were higher than non-occurrence group ( P<0.05) . The occurrence group with alanine aminotransferase (ALT) , glutamine transpeptidase (GGT) and aspartate aminotransferase (AST) were all higher than non-occurrence group ( P<0.05) .The folate, TGAb, and TPOAb levels were factors influencing adverse pregnancy outcomes in pregnant women with hypothyroidism ( P<0.05) . The area under the curve (AUC) values of folate, TGAb, TPOAb and their combined prediction of adverse pregnancy outcomes in pregnant women with hypothyroidism during pregnancy were 0.804, 0.843, 0.799, 0.909 ( P<0.05) , while the combined three with AUC values were higher ( P<0.05) . Conclusion:The folate, TGAb and TPOAb levels in early pregnancy can be used to evaluate adverse pregnancy outcomes in hypothyroidism pregnant women, and the combination of the three has a higher evaluation value.
