Radiopharmaceuticals operate by combining radionuclides with carriers. The radiation energy emitted by radionuclides is utilized to selectively irradiate diseased tissues while minimizing damage to healthy tissues. In comparison to external beam radiation therapy, radionuclide drugs demonstrate research potential due to their biological targeting capabilities and reduced normal tissue toxicity. This article reviews the applications and research progress of radiopharmaceuticals in cancer treatment. Several key radionuclides are examined, including ²²³Ra, ⁹⁰Y, Lutetium-177 (¹⁷⁷Lu), ²¹²Pb, and Actinium-225 (²²⁵Ac). It also explores the current development trends of radiopharmaceuticals, encompassing the introduction of novel radionuclides, advancements in imaging technologies, integrated diagnosis and treatment approaches, and equipment-medication combinations. We review the progress in the development of new treatments, such as neutron capture therapy, proton therapy, and heavy ion therapy. Furthermore, we examine the challenges and breakthroughs associated with the clinical translation of radiopharmaceuticals and provide recommendations for the research and development of novel radionuclide drugs.

Mitochondrial dysfunction in chondrocytes is a key pathogenic factor in osteoarthritis (OA), but directly modulating mitochondria in vivo remains a significant challenge. This study is the first to verify a correlation between mitochondrial dysfunction and the downregulation of the FOXO3 gene in the cartilage of OA patients, highlighting the potential for regulating mitophagy via FOXO3 gene modulation to alleviate OA. Consequently, we developed a chondrocyte-targeting CRISPR/Cas9-based FOXO3 gene-editing tool (FoxO3) and integrated it within a nanoengineered 'truck' (NETT, FoxO3-NETT). This was further encapsulated in injectable hydrogel microspheres (FoxO3-NETT@SMs) to harness the antioxidant properties of sodium alginate and the enhanced lubrication of hybrid exosomes. Collectively, these FoxO3-NETT@SMs successfully activate mitophagy and rebalance mitochondrial function in OA chondrocytes through the Foxo3 gene-modulated PINK1/Parkin pathway. As a result, FoxO3-NETT@SMs stimulate chondrocytes proliferation, migration, and ECM production in vitro, and effectively alleviate OA progression in vivo, demonstrating significant potential for clinical applications.

Objective To observe the clinical effect of doing Huatuo five-animal play treating blood-stasis-type silent myocardial ischemia(SMI)and its influence on coronary hemodynamics.Methods Ninety patients diagnosed as silent myocardial ischemia were randomly divided into a five-animal play group(n=45,age:51.56±11.00 years,24 males and 21 females)and a regular exercise group(n=45,age:52.44±7.19 years old,24 males and 21 females)according to a random number table.The five-animal play group practised the traditional five-animal play,while the regular exercise group con-ducted daily 30-minute moderate-intensity treadmill aerobic exercise,five times a week,for 4 weeks.The changes in the number of abnormal ST-T segment occurrences,myocardial oxygen consumption(CMO),coronary ischemia threshold(CIT),and blood smoothness index(BSD)within 24-hour ambu-latory electrocardiogram before and after the intervention were observed in both groups,with the thera-peutic effect and hemodynamic characteristics of both groups evaluated.Results The average number of ST-T segment abnormalities decreased after intervention in both groups(P<0.001),with significantly greater improvement in the five-animal play group than the regular exercise group(P<0.001).More-over,the average CMO decreased significantly,while the average CMR and BSD increased significant-ly in both groups after intervention(P<0.05),with significantly greater improvement in the five-ani-mal play group than the other group.Meanwhile,the total effective rate in the five-animal play group was significantly higher than the regular exercise group(P<0.01).Conclusion Undergoing the five-ani-mal play and moderate intensity treadmill aerobic exercise both are effective in treating silent myocardi-al ischemia.However,the former therapy is superior to the latter in bettering CMO,CIT and BSD.

Objective:Using surface-based morphometry (SBM), this study longitudinally tracks dynamic changes in whole-brain cortical morphological parameters in depression patients before and after vortioxetine treatment. Through three-dimensional topological characterization, we investigate the neuroanatomical correlations between cortical structural reorganization and improvements in affective symptoms and cognitive functions.Methods:Prospectively collected clinical data from 22 outpatients with depression (10 males and 12 females, aged 18-50 years, mean age 28.1±9.1) who attended Beijing Huilongguan Hospital clinic from October 2018 to December 2019. An age-matched healthy control group ( n=21; 10 males and 11 females, aged 22-44 years, mean age 30.8±6.6) was recruited concurrently. The Hamilton Rating Scale for Anxiety (HAMA), the 17-item Hamilton Depression Scale (HAMD 17), and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) were used to evaluate the severity of depressive symptoms and cognitive function in patients. Structural magnetic resonance imaging (sMRI) was performed to assess brain structural indices in depression patients before and after vortioxetine treatment, as well as in healthy controls. Whole-brain cortical structure measurements were calculated for all subjects using CAT12 software. Paired-sample t-tests were used to compare changes in cortical structure and clinical scale scores in depression patients before and after treatment, and two-sample t-tests were conducted to compare whole-brain cortical structure differences between patients (pre-and post-treatment) and healthy controls. Multiple regression analysis in SPM 12 was applied to examine the correlation between post-treatment cortical structural indices and clinical and cognitive scale scores in patients. Spearman correlation analysis was used to evaluate the correlation between changes in whole-brain cortical structure and cognitive function before and after vortioxetine treatment. Results:After vortioxetine treatment, patients with depression exhibited significant reductions in HAMA and HAMD 17 scores, along with significant increases in immediate memory, delayed memory, and total RBANS scores, with statistically significant differences observed ( t=8.43, 12.28, -4.71, -2.41, -3.86 respectively; all P<0.05), while there were no significant changes in visual span, language function, or attention ( P>0.05). Compared to healthy controls, depression patients showed a significantly reduced gyrification index in the right insula/superior temporal gyrus before treatment (28.74±1.20 vs 27.44±1.17; t=4.47, P<0.001), but no significant differences in whole-brain cortical structure were observed before and after treatment or between post-treatment patients and healthy controls ( P>0.05). Correlation analysis indicated that fractal dimension was negatively correlated with HAMA and HAMD 17 scores after treatment, while gyrification index was positively correlated with HAMD 17 ( rpartial=-0.79, -0.83, 0.72; P<0.05). Visual span was positively correlated with fractal dimension ( rpartial=0.78) and negatively correlated with gyrification index ( rpartial=-0.73, P<0.05). Sulcal depth was negatively correlated with attention and RBANS total scores ( rpartial=-0.77, -0.75; P<0.05). Additionally, changes in gyrification index in the left fusiform gyrus were positively correlated with changes in attention ( r=0.51), changes in gyrification index in the left posterior cingulate gyrus were positively correlated with changes in immediate memory ( r=0.58), and changes in sulcal depth in the left superior frontal gyrus were negatively correlated with changes in language ability ( r=-0.79) (both P<0.05). Conclusion:Vortioxetine treatment can improve anxiety and depressive symptoms in depression patients, as well as enhance certain cognitive functions, while also affecting cortical structure in the specific cortical area. Changes in cortical structure after vortioxetine treatment are closely related to clinical symptom improvement and cognitive function changes.

OBJECTIVE To explore the mechanisms of the flavonoids from new "Zhe Eight Flavors" Quzhou Fructus Aurantii(PTFC) against hepatocellular carcinoma based on the prediction of network pharmacology and experimental verification. METHODS From TCMSP, TCMID, ETCM, BATMAN-TCM and SwissTargetPrediction databases, the potential target proteins of PTFC, including naringin, narirutin and neohesperidin were collected. Based on the GeneCards, CTD, Disgenet, and OMIM databases, a set of target proteins for hepatocellular carcinoma was constructed. Taking the intersection of potential target proteins of PTFC and target proteins of hepatocellular carcinoma, key target proteins were obtained and a protein-protein interaction network was established. Besides, GO function and KEGG pathway enrichment analysis on the core target proteins was performed and a Compounds-Targets-Pathways-Disease network was constructed. Through proliferation, cloning, wound healing, and migration experiments, the effects of PTFC on the viability of HepG2 liver cancer cells were analyzed. Using fluorescence probe staining the impacts of PTFC on the mitochondrial membrane potential and apoptosis of HepG2 were observed. Finally, the validation of the regulatory effect of PTFC on the key predicted target PRKCA were carried out through RT-qPCR. RESULTS Based on network pharmacology, a total of 217 potential target proteins for PTFC were screened, with 59 intersecting target proteins related to diseases, including ALB, ESR1, PRKCA, and others. GO functional and KEGG pathway enrichment analysis revealed that the PTFC target proteins were involved in 193 biological processes and 13 cancer-related signaling pathways. Experimental results demonstrated that PTFC could impact the proliferation, cloning, wound healing, and migration abilities of liver cancer cells, leading to a decrease in mitochondrial membrane potential and promoting cell apoptosis. The results of RT-qPCR confirmed a significant downregulation of PRKCA expression by PTFC, validating the predictions made by network pharmacology analysis. CONCLUSION This study has revealed the potential molecular mechanism of PTFC treating hepatocellular carcinoma via the PRKCA target, laying the foundation for clinical application of PTFC.

Objective To analyze the prognostic value of preoperative peripheral blood inflammatory markers neutrophil to lymphocyte ratio(NLR)combined with tumor markers carcinoembryonic antigen(CEA)and glycoprotein antigen CA19-9 in patients with colon cancer.Methods A retrospective study was conducted on 158 cases of colon cancer patients who visited the 1st Affiliated Hospital of Kunming Medical University from May 2018 to October 2020.The receiver operating characteristic curve(ROC)was used to determine the critical values of various indicators and group them.The Kaplan Meier method was used to analyze the relationship between NLR,CEA,CA19-9,and combined detection of different groups and patient survival prognosis.Multivariate Cox regression analysis was used to analyze the factors affecting patient prognosis.Results The preoperative NLR level(P=0.035),combined testing group(P=0.008),and postoperative pathological N stage(P＜0.001)were independent risk factors for OS,and the joint testing group had the highest risk ratio among preoperative indicators(P=0.008,HR=2.664,95％CI 1.503～4.315).Conclusion The combined detection of NLR,CEA,and CA19-9 in peripheral blood before surgery has independent prognostic value for patients with colon cancer.
