Integrin α v β 3 is overexpressed in various tumor cells and angiogenesis. To date, no drug has been proven to target it for therapy. A first-in-human study was designed to investigate the safety, pharmacokinetics, and dosimetry of 177Lu-AB-3PRGD2, a novel integrin α v β 3-targeting radionuclide drug with an albumin-binding motif to optimize the pharmacokinetics. Ten patients (3 men, 7 women; aged 45 ± 16 years) with integrin α v β 3-avid tumors were recruited to accept 177Lu-AB-3PRGD2 injection in a dosage of 1.57 ± 0.08 GBq (42.32 ± 2.11 mCi), followed by serial scans to obtain its dynamic distribution in the body. Safety tests were performed before and every 2 weeks after the treatment for 6-8 weeks. No adverse event over grade 3 was observed. 177Lu-AB-3PRGD2 was excreted mainly through the urinary system, with intense radioactivity in the kidneys and bladder. Moderate distribution was found in the liver, spleen, and intestines. The estimated blood half-life was 2.85 ± 2.17 h. The whole-body effective dose was 0.251 ± 0.047 mSv/MBq. The absorbed doses were 0.157 ± 0.032 mGy/MBq in red bone marrow and 0.684 ± 0.132 mGy/MBq in kidneys. This first-in-human study of 177Lu-AB-3PRGD2 treatment indicates its promising potential for targeted radionuclide therapy of integrin α v β 3-avid tumors. It merits further studies in more patients with escalating doses and multiple treatment courses.

Vascular damage plays a significant role in the onset and progression of Alzheimer's disease (AD). However, the precise molecular mechanisms underlying the induction of neuronal injury by vascular damage remain unclear. The present study aimed to examine the impact of fibrinogen (Fg) on tau pathology. The results showed that Fg deposits in the brains of tau P301S transgenic mice interact with tau, enhancing the cytotoxicity of pathological tau aggregates and promoting tau phosphorylation and aggregation. Notably, Fg-modified tau fibrils caused enhanced neuronal apoptosis and synaptic damage compared to unmodified fibrils. Furthermore, intrahippocampal injection of Fg-modified tau fibrils worsened the tau pathology, neuroinflammation, synaptic damage, neuronal apoptosis, and cognitive dysfunction in tau P301S mice compared to controls. The present study provides compelling evidence linking Fg and tau, thereby connecting cerebrovascular damage to tau pathology in AD. Consequently, inhibiting Fg-mediated tau pathology could potentially impede the progression of AD.

Diabetes mellitus (DM) is a metabolic disease caused by absolute or relative insulin deficiency and reduced insulin sensitivity in peripheral cells, posing a serious threat to global health. Chronic complications arising in the later stages of DM can lead to the decline or even loss of function in multiple organs, including the eyes, heart, liver, kidneys, nerves, and feet, making them the primary cause of mortality in DM patients. Although modern medicine has made some progress in the treatment of these complications, challenges such as high costs and adverse drug reactions remain. Thus, identifying highly effective drugs with minimal adverse effects has become a top priority. Astragalus membranaceus is a shining gem in the treasure trove of Chinese medicine. Numerous studies have shown that its primary active component, astragaloside Ⅳ, possesses various biological activities, including anti-inflammatory, antioxidant, and antiviral effects, as well as benefits for cardiac and cerebral function, nerve conduction, and myocardial protection. Meanwhile, the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway plays a crucial role in regulating oxidative stress, inflammatory responses, apoptosis, and autophagy. Extensive research has highlighted the significant role of this pathway in various DM complications, leading to widespread studies on its interaction with astragaloside Ⅳ. This review summarizes research findings on how astragaloside Ⅳ alleviates pancreatic cytotoxicity in DM patients by modulating the PI3K/Akt pathway. Additionally, it highlights its protective effects on basic cardiac function, inhibition of retinal cell damage, improvement of cerebral nerve dysfunction, reduction of chronic kidney and liver damage, and mitigation of neurovascular toxicity in the lower limbs. These insights provide a valuable reference for the clinical application of A. membranaceus and its active monomer, astragaloside Ⅳ, in the treatment of DM and its complications.

Objective:To explore the value of serum soluble E-cadherin (sEC) and cyclooxygenase-2 (COX-2) levels in predicting postoperative recurrence and metastasis of breast cancer.Methods:198 female breast cancer patients who underwent surgical treatment in Huai’an Hospital Affiliated to Xuzhou Medical University (Huai’an Second People’s Hospital) From Mar. 2023 to Mar. 2025 were selected and followed up for 3 years. The recurrence and metastasis were counted. Patients with recurrence and metastasis were included in the poor prognosis group, and patients without recurrence and metastasis were included in the good prognosis group. The general data, preoperative serum sEC and COX-2 levels were compared between the two groups. The influencing factors of recurrence and metastasis of breast cancer after operation were analyzed. The dose-response relationship and predictive value of serum sEC and COX-2 levels with recurrence and metastasis were analyzed. Logistic regression equation (LR) model 1 was constructed according to conventional influencing factors, and LR model 2 was constructed according to conventional influencing factors combined with serum sEC and COX-2. The predictive efficacy and accuracy of the two models were analyzed by receiver operating characteristic curve (ROC) and calibration curve. According to the ratio of 7∶3, another 85 female breast cancer patients who underwent surgical treatment in Huai’an Hospital Affiliated to Xuzhou Medical University (Huai’an Second People’s Hospital) from May. 2023 to May. 2025 were selected for external validation (validation set) .Results:Among 198 breast cancer patients who underwent postoperative follow-up for 3 years, 3 cases were lost to follow-up, and the recurrence and metastasis rate among the 195 patients who completed the 3-year postoperative follow-up was 26.15% (51/195). In the good prognosis group, the proportion of TNM stage III was 20.14%, the proportion of lymph node metastasis was 11.81%, the preoperative serum carbohydrate antigen 153 (CA153) level was (54.19±10.84) U/mL, the carbohydrate antigen 125 (CA125) level was (46.03±10.27) U/mL, the sEC level was (1987.65±191.37) ng/mL, and the COX-2 level was (17.85±5.21) ng/mL. In the poor prognosis group, the proportion of TNM stage III was 45.10%, the proportion of lymph node metastasis was 35.29%, the preoperative serum CA153 level was (65.87±12.23) U/mL, the CA125 level was (57.76±11.51) U/mL, the sEC level was (2 295.37±261.48) ng/mL, and the COX-2 level was (10.42±3.16) ng/mL. Compared with the good prognosis group, they were increased ( t/χ 2=12.00, 14.11, 6.39, 6.79, 8.92, 12.00, P<0.05). Multivariate Logistic regression analysis showed that TNM stage III ( OR=2.078, 95%CI =1.569-2.751, P<0.05), lymph node metastasis ( OR=2.435, 95 %CI=1.843-3.216, P<0.05), serum CA153 ( OR= 1.180,95 %CI=1.026-1.357, P<0.05), CA125 ( OR=1.206,95 %CI=1.033-1.408, P<0.05), sEC ( OR=1.011,95 %CI= 1.007-1.015, P<0.05), COX-2 ( OR=1.378,95 %CI=1.128-1.683, P<0.05) were independent risk factors for postoperative recurrence and metastasis of breast cancer. Restricted cubic spline (RCS) analysis showed that serum sEC and COX-2 levels were positively correlated with the risk of recurrence and metastasis of breast cancer ( P<0.05). ROC analysis showed that serum sEC (AUC=0.762,95 %CI=0.696-0.820, P<0.05) and COX-2 (AUC=0.757,95 %CI=0.691-0.815, P<0.05) could be used as biological indicators to predict postoperative recurrence and metastasis of breast cancer. The AUC of LR model 1 in predicting postoperative recurrence and metastasis of breast cancer was 0.862 (95 %CI=0.805-0.907, P<0.05). The AUC of LR model 2 in predicting postoperative recurrence and metastasis of breast cancer was 0.965 (95 %CI= 0.891-0.983, P<0.05), which was significantly larger than that of LR model 1 ( Z=2.015, P<0.05). The calibration curve analysis showed that the calibration degree of LR model 1 in predicting postoperative recurrence and metastasis of breast cancer was good, and the prediction results were in good agreement with the actual observation results. The calibration degree of LR model 2 was high, and the prediction results were in good agreement with the actual observation results. The results of external validation showed that the sensitivity of LR model 2 in predicting postoperative recurrence and metastasis of breast cancer was 82.61%, the specificity was 93.55%, the accuracy was 90.59%, and the Kappa value was 0.762 (95 %CI: 0.549-0.974) . Conclusions:Preoperative serum sEC and COX-2 levels are independent risk factors for postoperative recurrence and metastasis of breast cancer. They can be used as biological indicators to predict postoperative recurrence and metastasis of breast cancer. Combined with conventional indicators, they can significantly improve the predictive efficacy.

Objective:To analyze the significance of ultrasound super microvascular imaging (SMI) combined with strain ratio (SR) in the differential diagnosis of benign and malignant breast masses.Methods:A total of 110 patients with breast masses (110 lesions) admitted to Jiande Branch of the Second Affiliated Hospital of Zhejiang University from October 2022 to November 2024 were retrospectively selected, including 65 benign masses (benign group) and 45 malignant masses (malignant group). Both groups received SMI and strain elastography (SE) examination. The clinical and ultrasonic parameters SMI blood flow signal grade, vascular index (VI), global SR (ESR), local SR (LSR) and other indicators of the two groups were compared, and the independent risk of breast tumor malignancy was screened by Logistic regression. Receiver operating characteristic (ROC) curve was used to analyze the value of SMI blood flow signal grading, VI and ESR combined detection in the differential diagnosis of breast tumor malignancy.Results:The proportion of irregular shape, unclear boundary, microcalcification, convergence sign and angulation sign in the malignant group were higher than those in the benign group: 80.00%(36/45) vs. 55.38%(36/65), 57.78%(26/45) vs. 33.85%(22/65), 44.44%(20/45) vs. 13.85%(9/65), 55.56%(25/45) vs. 9.23%(6/65), 60.00%(27/45) vs. 15.38%(10/65), there were statistical differences ( P<0.05). The SMI blood flow signal grade in the malignant group was higher than that in the benign group, the VI, ESR and LSR in the malignant group were higher than those in the benign group: (6.53 ± 0.68)% vs. (3.14 ± 0.36)%, 4.62 ± 0.48 vs. 2.53 ± 0.27, 31.45 ± 3.29 vs. 20.16 ± 2.35, there were statistical differences ( P<0.05). Logistic regression analysis showed that irregular shape, unclear boundary, microcalcification, SMI blood flow signal grade, VI and ESR were independent risk factors for malignant breast mass ( P<0.05). ROC curve analysis results showed that the sensitivity, specificity and accuracy of SMI blood flow signal classification, VI and ESR combined in predicting breast tumor malignancy were 84.26%, 83.17% and 87.65%, respectively, and the area under the curve was 0.896, which were higher than the results predicted by each index alone. Conclusions:There are certain characteristic changes of SMI in benign and malignant breast masses. SMI combined with SR has good value in differential diagnosis of benign and malignant breast masses.
