High-performance phototheranostics with combined photothermal therapy and photoacoustic imaging have been considered promising approaches for efficient cancer diagnosis and treatment. However, developing phototheranostic materials with efficient photothermal conversion efficiency (PCE), especially over the second near-infrared window (NIR-II, 1000-1700 nm), remains challenging. Herein, we report an ultraefficient NIR-II-activated nanomedicine with phototheranostic and vaccination capability for highly efficient in vivo tumor elimination and metastasis inhibition. The NIR-II nanomedicine of a semiconducting biradical oligomer with a motor-flexible design was demonstrated with a record-breaking PCE of 87% upon NIR-II excitation. This nanomedicine inherently features extraordinary photothermal stability, good biocompatibility, and excellent photoacoustic performance, contributing to high-contrast photoacoustic imaging in living mice and high-performance photothermal elimination of tumors. Moreover, a whole-cell vaccine based on a NIR-II nanomedicine with NIR-II-activated performance was further designed to remotely activate the antitumor immunologic memory and effectively inhibit tumor occurrence and metastasis in vivo, with good biosafety. Thus, this work paves a new avenue for designing NIR-II active semiconducting biradical materials as a promising theranostics platform and further promotes the development of NIR-II nanomedicine for personalized cancer treatment.

Metastatic castration-resistant prostate cancer（mCRPC）is the terminal stage of prostate cancer，often associated with poor prognosis and limited treatment options. Prostate-specific membrane antigen（PSMA），a type Ⅱ transmembrane glycoprotein，is highly expressed on the surface of most prostate cancer cells. The expression level of PSMA is significantly associated with tumor migration and invasion，making it a critical target in the diagnosis and treatment of prostate cancer. In recent years，radioligand therapy（RLT）targeting PSMA has rapidly advanced. 177Lu-PSMA-617 delivers beta radiation from 177Lu to selectively kill prostate cancer cells by inducing DNA damage. 177Lu-PSMA-617 has demonstrated promising efficacy and safety in mCRPC，gaining widespread endorsement in global prostate cancer guidelines. This review summarizes the mechanism，clinical evidence，and progress of RLT，with a focus on 177Lu-PSMA-617，offering insights for clinical practice and research.

BACKGROUND:Mongolian medicine Echinops sphaerocephalus L.is a commonly used medicine for bone injury in Mongolian medicine.It is effective for tendon injury,fracture,bone nonunion,bone fever,tingling,sore and other diseases.Our previous studies have confirmed that Mongolian medicine Echinops sphaerocephalus L.can promote the proliferation and osteogenic differentiation of bone marrow mesenchymal stem cells,but its effect on angiogenesis in the process of bone defect repair is unknown.OBJECTIVE:To investigate the effect of Echinops sphaerocephalus L.on in vitro angiogenesis in human umbilical vein vascular endothelial cells and to explore the angiogenesis-promoting active ingredients and their mechanisms of action of Echinops sphaerocephalus L.using network pharmacology technology.METHODS:The ethanol extract of Echinops sphaerocephalus L.was prepared and preserved by freeze-drying.The proliferation,migration,chemotaxis and angiogenesis of human umbilical vein endothelial cells were observed after treatment with different concentrations(1 000,100,and 10 μg/mL)of Echinops sphaerocephalus L.The active components and possible signaling pathways that promoted angiogenesis were enriched and analyzed by network pharmacology.RESULTS AND CONCLUSION:(1)The effect of Echinops sphaerocephalus L.on angiogenesis was regulated by its mass concentration:at low mass concentration(10 μg/mL),Echinops sphaerocephalus L.could promote the proliferation,migration,chemotaxis and angiogenesis of human umbilical vein vascular endothelial cells;on the contrary,Echinops sphaerocephalus L.inhibited the proliferation,migration,and chemotaxis of human umbilical vein endothelial cells at high mass concentration(1 000 μg/mL).However,the inhibitory effect of Echinops sphaerocephalus L.on angiogenesis was not significant at high mass concentration due to the limitation of experimental time.10 μg/mL Echinops sphaerocephalus L.could up-regulate the mRNA expression of angiogenesis-associated factors,including kinase insert domain receptor,vascular endothelial growth factor A,and hypoxia-inducible factor α,and thereby influenced angiogenesis during bone repair.(2)Network pharmacological analyses indicated that Echinops sphaerocephalus L.may bind to eight core targets(TGFB1,TNF,IL-6,STAT3,CTNNB1,IL-1B,AKT1,and HIF-1A)through four core active components(apigenin,caffeic acid,quercetin,and chlorogenic acid)to exert an effect on angiogenesis,atherosclerosis,multiple viral infections,and tumor angiogenesis-related signaling pathways.

Objective To investigate the relationship between ventricular arterial coupling(VAC)and haemodynamics of patients with sepsis and the predictive value for the 28-day prognosis.Methods A total of 164 patients with sepsis were selected and given fluid resuscitation treatment(infusion of 30 mL/kg of crystalloid over 3 h),and changes of VAC[effective aortic elasticity(Ea)/ventricular end-systolic elasticity(Ees)]values and hemodynamic parameters of patients resuscitated for 0 h,24 h and 72 h were observed.The difference between Ea/Ees for 24 h and 72 h of resuscitation and 0 h was calculated.Pearson method was used to analyze the correlation between Ea/Ees and Δcentral venous pressure(CVP),Δspiratory volume index(SVI)and Δcardiac index(CI).According to the 28-day prognosis,patients were divided into two groups:the survival group(123 cases)and the death group(41 cases).General information was collected in two groups of patients.The predictive values of 24 h ΔEa/Ees and 72 h ΔEa/Ees for 28-day death in sepsis patients were analyzed by multivariate Cox regression models and receiver operating characteristics(ROC)curve.Results The Ea/Ees of 164 patients resuscitated for 24 h and 72 h were lower than those of 0 h,and the Ea/Ees of 72 h was lower than that of 24 h(all P<0.05).CVP,SVI and CI of 164 patients resuscitated for 24 h and 72 h were higher than those of 0 h,and the CVP,SVI and CI of 24 h was higher than that of 72 h(all P<0.05).The 24 h ΔEa/Ees was significantly lower than that of 72 h ΔEa/Ees(P<0.05),and 24 h ΔCVP,SVI and CI were higher than those of 72 h(P<0.05).There was a negative correlation between 24 h ΔEa/Ees and 24 h ΔCVP,24 h ΔSVI and 24 h ΔCI(P<0.05).Acute Physiology and Chronic Health Status Score II(APACHE Ⅱ)≥20 points,Sequential Organ Failure Score(SOFA)≥10 points,24 h ΔEa/Ees and 72 h ΔEa/Ees were higher in the death group than those in the survival group(P<0.05).Elevated APACHE Ⅱ,SOFA,24 h ΔEa/Ees and 72 h ΔEa/Ees were risk factors affecting the 28-day prognosis of patients with sepsis(P<0.05).The 24-hour ΔEa/Ees and 72-hour ΔEa/Ees were more effective in predicting the 28 d prognosis of patients with sepsis(P<0.05).Conclusion Changes of Ea/Ees can better reflect the haemodynamic changes in sepsis patients in the early stages of treatment and help to predict the 28-day prognosis of sepsis patients.
