By analyzing medical painting artworks from ancient and modern times， both in China and abroad， this paper explored the visual narrative functions and their historical evolution. The study revealed that in ancient times， medical painting art was mostly set against religious and mythological backgrounds， portraying the mysterious and supernatural aspects of disease. With the advent of the Renaissance， painting art gradually broke free from religious constraints and began to depict disease more realistically. In modern times， painting art has further embodied humanistic care and ethical spirit， and has gradually integrated narrative therapy and health communication， reflecting the integration of medical science and humanistic spirit. This evolutionary process not only witnessed the development of medical science and the transformation of human health concepts but also revealed the changes in the narrative characteristics of medical painting art from obscurity to clarity， from metaphor to concreteness， and from a one-sided focus on biological aspects to an emphasis on medical， social， and humanistic aspects.

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.

Objective To investigate the prevalence of scoliosis and congenital heart disease(CHD)and their correlation among children and adolescents of Drung nationality in Yunnan Province.Methods A cross-sectional survey was conducted in November 2022 among all Drung school-aged children and adolescents aged 5-18 years in Gongshan Drung and Nu Autonomous County,Yunnan Province.Visual inspection,Adams for-ward flexion test,and trunk rotation angle(ATR)measurement were comprehensively used for school prelim-inary screening of scoliosis.Individuals who tested positive in the school preliminary screening underwent fur-ther X-ray examination for auxiliary diagnosis.Cardiac auscultation and echocardiography were used for school preliminary screening of CHD.The personal information of the screening subjects,the screening results,etc.were recorded.The prevalence of scoliosis and CHD among children and adolescents of the Drung nationality and the relationship between the two diseases were statistically analyzed,and the positive predictive value of school-based scoliosis screening and its influencing factors were also analyzed.Results A total of 1 036 chil-dren and adolescents of Drung nationality were enrolled,with a mean age of(10.72±3.75)years,icluding 542 males and 494 females.A total of 45 subjects tested positive for scoliosis in the school preliminary screening,with a preliminary positive rate of 4.34%.A total of 22 cases were finally diagnosed with scoliosis,with a prevalence rate of 2.12%.Among them,21 cases were idiopathic scoliosis(accounting for 95.45%),and 1 case was congenital scoliosis(accounting for 4.55%).The prevalence rate was higher in females(2.83%)than that in males(1.48%),higher in the 10 to 18-year-old group(2.30%)than that in the 5 to<10-year-old group(1.87%),and higher in the secondary school group(2.78%)than that in the primary school group(1.78%),hut there were no statistically significant differences(P>0.05).Most idiopathic scoliosis cases were mild(Cobb angle 10° to<20°,90.48%)and classified as Lenke type Ⅴ(57.14%).Two cases of CHD were confirmed,both of which were atrial septal defects,with a prevalence rate of 0.19%.The co-occurrence rate of idiopathic scoliosis and CHD was 4.76%(1/21).The positive predictive value of school-based scoliosis pre-liminary screening was only 48.89%.When the BMI was<18.5 kg/m2,the positive predictive value was sig-nificantly higher than that for BMI≥18.5 kg/m2(P<0.05).Conclusion The prevalence rate of scoliosis a-mong adolescents of the Drung ethnic group in Yunnan Province is 2.12%,predominantly idiopathic scoliosis,with Lenke type V being the most common classification.The prevalence rate of congenital heart disease is 0.19%.BMI is a significant influencing factor for the positive predictive value of school-based scoliosis prelimi-nary screening.

Objective This study aimed to explore the correlation between abnormal hand features and coronary atherosclerotic heart disease(CHD)to provide clinical data support for digitalized traditional Chinese medicine(TCM)hand diagnosis.Methods A palm key point prediction algorithm was used to automatically capture and collect detailed features of the palm and nails through image analysis and data mining using the hand diagnosis information collection technology based on the NVIDIA Jetson platform and Qt framework.A total of 438 cardiac patients who underwent coronary artery computed tomography angiography(CACTA)in the Department of Cardiology,Dongzhimen Hospital,Beijing University of Chinese Medicine,from December 2023 to April 2024 were included and divided into CHD(148 cases)and non-CHD groups(290 cases)based on the CACTA results.The hand features of the two groups were compared,and abnormal hand features associated with CHD were screened using random forest analysis as well as univariate and multivariate logistic regression analyses.Results Based on the results of univariate logistic regression and random forest analyses,a set of hand-related features associated with CHD were identified and subsequently included in the multivariate logistic regression analysis.These features included the morphology of the thenar eminence,the wrinkles of the thenar eminence,nail shape,nail texture,and the length of the blood vessel in the middle finger.Multivariate logistic regression analysis revealed that hypertrophic thenar eminence[odds ratio(OR):3.049,95%confidence interval(CI):1.430-6.503,P=0.004],presence of wrinkles on the thenar eminence(OR:2.206,95%CI:1.119-4.348,P=0.022),presence of gray-black vertical stripes on the nails(OR:1.981,95%CI:1.173-3.347,P=0.011),uneven nail surface(OR:3.130,95%CI:1.822-5.378,P<0.001),and inward-bending nail surface(OR:5.727,95%CI:1.812-18.102,P=0.003)were positively associated with CHD.In contrast,the blood vessel in the middle finger longer than 1/3 of the phalanx was negatively associated with CHD(OR:0.405,95%CI:0.234-0.702,P=0.001).Conclusion Certain hand features are significantly associated with CHD,providing the valuable clinical data to support for the digitalization of TCM hand diagnosis.

Objective:To investigate the mechanism of Fusobacterium nucleatum ( Fn) in regulating the formation of neutrophil extracellular trap (NET) to aggravate colitis. Methods:With a completely randomized design, 15 C57BL/6 mice were randomly divided into negative control group, dextran sulfate sodium (DSS) A group (DSS-induced colitis), and DSS+ Fn A group (DSS-induced colitis with Fn infection); another 15 C57BL/6 mice were randomly divided into DSS B group, DSS+ Fn B group, and GSK484 group (DSS-induced colitis with Fn infection and followed by intraperitoneal injection of peptidylarginine deiminase 4 (PAD4)inhibitor GSK484), with 5 mice in each group. The Fn-infected neutrophils (HL-60 cell) model and PAD4-inhibited cell model were established and divided into neutrophil-like control cell (induced with 1.25% dimethylsulfoxide), Fn+ neutrophil-like cell (neutrophil-like cells co-cultured with Fn), and GSK484 cell ( Fn+ neutrophil-like cell co-cultured with GSK484) with a completely randomized design. The neutrophil-like control and Fn+ neutrophil-like cells were divided into 2 batches to conduct experiments before and after PAD4 inhibition separately.The expression of zonula occludens-1 (ZO-1), neutrophil elastase (NE), reactive oxygen species, PAD4, and citrullinated histone H3(cit-H3) were analyzed by immunohistochemistry staining, Western blotting, and flow cytometry assay. Two-tailed t test was used for statistical analysis. Results:The results of immunohistochemical staining showed that compared with those of the DSS A group, the expression levels of NE, PAD4 and cit-H3 of the DSS+ Fn A group were upregulated, and the expression level of ZO-1 was downregulated; compared with those of the DSS+ Fn B group, the expression level of ZO-1 of the GSK484 group was upregulated, and the expression levels of cit-H3 and PAD4 were downregulated. The results of Western blotting demonstrated that, before the PAD4 inhibition, the expression levels of NE, PAD4 and cit-H3 of the Fn+ neutrophil-like cell were all higher than those of the neutrophil-like control cell (1.52±0.11 vs. 1.00±0.19, 1.21±0.06 vs. 1.00±0.07, 1.59±0.16 vs. 1.00±0.16), and the differences were statistically significant ( t=-4.13, -3.86, and -4.47; P=0.014, 0.014, and 0.018); after the PAD4 inhibition, the expression levels of PAD4, cit-H3, and NE of the GSK484 cell were all lower than those of the Fn+ neutrophil-like cell (0.95±0.09 vs. 1.27±0.04, 1.15±0.34 vs. 2.29±0.50, 1.22±0.14 vs. 1.68±0.12), and the differences were statistically significant ( t=5.61, 3.24, and 4.49; P=0.005, 0.032, and 0.011). The results of flow cytometry assay indicated that the positive rate of reactive oxygen species of the DSS+ Fn A group was higher than that of the DSS A group ((21.15±2.93)% vs. (11.14±1.42)%), and the positive rate of reactive oxygen species of the Fn+ neutrophil-like cell was also higher than that of the neutrophil-like control cell before the PAD4 inhibition ((51.69±6.94)% vs.(31.95±3.31)%), and the differences were statistically significant( t=5.33 and 4.45, P=0.006 and 0.011). Conclusion:Fn can promote neutrophil to release NET by upregulating reactive oxygen/PAD4/cit-H3 signaling pathway, which disrupt the intestinal barrier and aggravate colitis.

Objective:To explore the value of combining gut microbiota and clinical features for preoperative microvascular invasion (MVI) prediction in hepatocellular carcinoma (HCC).Methods:Clinical data and fecal samples were collected from 71 HCC patients who underwent curative resection at Ningbo Second Hospital between Jan 2023 and Aug 2024. Among them, 41 patients were assigned to the training set and 30 to the validation set. Gut microbiota composition was analyzed using 16S rRNA sequencing. Redundancy analysis (RDA) was used to evaluate the influence of clinical features on the microbiota. Differences in alpha and beta diversity between the MVI-negative and MVI-positive groups were assessed. Differential genera were identified using the Wilcoxon test and LEfSe analysis. A random forest model and Logistic regression were employed to screen key differential genera, followed by ROC analysis. Genera with high ROC values were further validated in the validation set.Results:RDA indicated that MVI was a key factor influencing gut microbiota composition. The random forest model (AUC=0.925), combined with Logistic regression analysis, identified four genera: Acidovorax ( OR=0.618), Tissierella ( OR=1.293), Chitinophaga ( OR=4.596), and Virgisporangium ( OR=0.960), as well as two clinical features: tumor diameter ( OR=0.668) and liver cirrhosis ( OR=14.011), as independent risk factors. ROC analysis showed that in the training set, the combination of Chitinophaga (AUC=0.71) and tumor diameter (AUC=0.75) had the best diagnostic performance (AUC=0.87). In the validation set, the combination of Virgisporangium (AUC=0.80) and tumor diameter (AUC=0.79) yielded the highest diagnostic performance (AUC=0.87). Conclusions:A genomics-based model combining gut microbiota and clinical features shows promising predictive value for noninvasive preoperative assessment of MVI status in HCC patients.

Objective To investigate the relationship between platelet to lymphocyte ratio(PLR)and low-density lipoprotein cholesterol(LDL-C)/high-density lipoprotein cholesterol(HDL-C)ratio with the degree of carotid artery stenosis,neurological deficits,and prognosis in elderly pa-tients with ischemic stroke and carotid artery stenosis.Methods A total of 186 elderly patients diagnosed with ischemic stroke and carotid artery stenosis admitted in our hospital from June 2021 to June 2024 were enrolled in this study.The PLR and LDL-C/HDL-C ratio were collected,and then with median split,they were divided into high and low PLR groups(both 93 cases),and high and low LDL-C/HDL-C groups(both 93 cases).General clinical data were compared between the two pairs of groups.Multivariate logistic regression analysis was used to identify the factors influencing the severity of carotid artery stenosis,neurological deficits,and prognosis.Kendall's Tau-b correlation analysis was employed to assess the relationship of PLR and LDL-C/HDL-C with the degree of carotid artery stenosis and prognosis.Pearson correlation analysis was conduc-ted to evaluate the association of PLR and LDL-C/HDL-C with neurological deficits.Results Sta-tistically differences were observed in the degree of carotid artery stenosis and prognosis between the high and low PLR groups(P＜0.01).The NIHSS score was significantly higher in the high PLR group(P＜0.01).Similar differences were noted between the high and low LDL-C/HDL-C groups in terms of degree of carotid artery stenosis and prognosis(P＜0.01).The NIHSS score was obviously higher in the high LDL-C/HDL-C group(P＜0.01).Multivariate logistic regression analysis showed that PLR and LDL-C/HDL-C were risk factors for the degree of carotid artery stenosis,neurological deficits and prognosis in elderly patients with carotid artery stenosis after ischemic stroke(OR=3.842,95％CI:2.551-5.328,P=0.000;OR=3.604,95％CI:2.402-5.407,P=0.000;OR=2.956,95％CI:1.955-4.471,P=0.000;OR=3.463,95％CI:2.506-4.785,P=0.000;OR=2.878,95％CI:1.991-4.160,P=0.000;OR=3.785,95％CI:2.483-5.768,P=0.000).Kendall's Tau-b correlation analysis showed that PLR and LDL-C/HDL-C were positively correlated with the degree of carotid artery stenosis and the prognosis in these eld-erly patients(P＜0.05).Pearson correlation analysis indicated that PLR and LDL-C/HDL-C were positively correlated with the NIHSS score in the patients(P＜0.05).Conclusion For the elderly ischemic stroke patients with carotid artery stenosis,PLR and LDL-C/HDL-C are related to the prognosis,and can be used to help assess the severities of carotid artery stenosis and neurological deficits.
