In response to the high risk of recurrence and metastasis after breast cancer surgery， this paper proposes a six-dimensional integrated preventive and therapeutic model， namely the "disease-syndrome-constitution-trend-strategy-efficacy" framework， including disease identification， syndrome differentiation， constitution differentiation， trend assessment， strategy implementation， and effect evaluation. This model builds upon the traditional three-dimensional approach of disease identification， syndrome differentiation and constitution differentiation， and introduces "trend" to dynamically capture the evolving tendencies of disease progression and the transformation of syndrome and constitution， thereby operationalizing the concept of "treating before disease onset". The "strategy" dimension enables the organic integration and individualized regulation of TCM and western medical interventions， while the "efficacy" dimension establishes a multidimensional evaluation system integrating TCM and western medicine to assess the efficacy of the "strategy"， so as to promote the systematic， dynamic， and precise development of treating before disease onset in TCM.

Steroid-induced avascular necrosis of femoral head（SANFH） is a bone and joint disease caused by prolonged and excessive steroid use. Its typical pathological features involve progressive circulatory disorders in the blood supply system of femoral head， leading to osteocyte apoptosis and bone tissue necrosis. As the disease progresses， it ultimately results in structural collapse and necrotic lesions of the femoral head， severely affecting patients' limb function and quality of life. Glucocorticoids mediate pathological damage through dual mechanisms， on the one hand， they disrupt the dynamic equilibrium between bone formation and resorption by suppressing osteoblast differentiation activity and activating osteoclastogenesis， on the other hand， they induce lipid metabolism disorders， inhibit angiogenesis， and impair endothelial cell function， thereby triggering microcirculatory disorders. Epimedii Folium and its active components exhibit multidimensional regulatory effects in SANFH prevention and treatment. Literature review reveals that it is rich in multiple active ingredients， primarily including total flavonoids of Epimedii Folium， icaritin， icariin， kaempferol， icariside Ⅱ， etc. These compounds exert multiple pharmacological effects（regulating bone metabolic homeostasis， modulating angiogenesis， correcting lipid metabolism disorders， and controlling cellular autophagy processes） through multiple signaling pathways， including Wnt/β-catenin， transforming growth factor（TGF）-β/bone morphogenetic protein（BMP）/Smad， mitogen-activated protein kinase（MAPK）， phosphoinositide 3-kinase/protein kinase B（PI3K/Akt）， osteoprotegerin/receptor activator of nuclear transcription factor-κB ligand/receptor activator of nuclear transcription factor-κB（OPG/RANKL/RANK）， etc. Based on existing research findings， this paper systematically elucidates the intervention mechanisms of active components in Epimedii Folium on key pathological processes of SANFH through the above pathways. It also deeply analyzes their regulatory roles in key nodes of different signaling pathways， aiming to provide valuable references for future clinical treatment and experimental research.

Liver fibrosis is caused by various factors such as viral infection， alcohol intake， and metabolism-related damage， leading to the replacement of normal tissue by fibrous scars. As a regulatory factor for cell proliferation， insulin-like growth factor 1 （IGF-1） participates in the regulation of cell cycle， the promotion of cell proliferation and differentiation， and the inhibition of cell apoptosis by binding to its receptor insulin-like growth factor-1 receptor （IGF-1R）. Studies have shown that the IGF-1/IGF-1R signaling pathway can regulate the process of liver fibrosis by affecting the senescence and apoptosis of hepatocytes， the activation and proliferation of hepatic stellate cells， and the dysfunction of endothelial cells. In addition， the IGF-1/IGF-1R signaling system can also regulate multiple mechanisms such as DNA damage repair， cell proliferation， lipid metabolism， cell senescence， and oxidative stress， thereby providing new strategies and potential targets for the prevention and treatment of liver fibrosis. This article summarizes the mechanism of action of IGF-1/IGF-1R and its signal transduction system in mediating liver fibrosis by regulating DNA damage repair in different cells， in order to provide a theoretical basis for the treatment of liver fibrosis.

ObjectiveTo explore the academic characteristics of contemporary renowned Chinese medicine masters in treating diabetic kidney disease （DKD） from the perspectives of principles， methods， formulas， and medications. MethodsIn strict accordance with the Systematic Review of Text and Opinion （SrTO） process developed by the Joanna Briggs Institute （JBI）， an Australian evidence-based healthcare center， the databases including China National Knowledge Infrastructure （CNKI）， VIP Database， Wanfang Data， and China Biomedical Literature Service System （SinoMed） were searched. Based on predefined inclusion and exclusion criteria， text information extraction， quality evaluation， and text information synthesis were conducted sequentially. The data were analyzed and presented in the form of text and figures. ResultsA total of 215 articles related to 43 contemporary renowned experts in the fields of Chinese medicine nephrology and endocrinology were included. The study found that the academic thoughts of these masters in the treatment of DKD are extensive， involving multiple levels such as disease understanding， therapeutic strategies， formula application， and medication use. In terms of disease understanding， the primary pathogenesis is characterized by deficiency in the root and excess in the manifestation. It is emphasized that internal factors， such as congenital endowment deficiency， interact with external factors such as improper diet， emotional disturbances， invasion of exogenous pathogens， and delayed or inappropriate treatment， to jointly induce the disease. This further gives rise to various pathogenetic theories， including obstruction of renal collaterals by blood stasis， toxin-induced damage to renal collaterals， latent wind disturbing the kidney， and internal heat leading to mass formation. In terms of therapeutic strategies and medication use， the principal treatment method is to replenish Qi and nourish Yin. Stage-based and syndrome-differentiated treatments are advocated. Flexible use of insect-derived drugs and wind-dispelling drugs is emphasized， along with proficiency in applying classical formulas and drug pairs. Integrated internal and external treatments， as well as the combined application of multiple therapeutic approaches， are commonly employed for comprehensive management. Meanwhile， the concept of "preventive treatment of disease" is upheld， and individualized long-term management of patients is advocated. ConclusionThrough the SrTO process， the academic thoughts of contemporary renowned Chinese medicine masters in the treatment of DKD have been systematically and standardly synthesized， providing a scientific and standardized basis for future theoretical exploration.

Objective:To study the implementation progress of the prevention and control measures for drinking water-borne endemic fluorosis and the changing trend of fluorosis conditions in Inner Mongolia Autonomous Region, comprehensively evaluate the effectiveness of prevention and control measures, and provide a basis for the next step of prevention and control of the disease.Methods:In 2015 and 2023, a cross-sectional survey method was used to investigate the water improvement situation, the operation of water improvement projects, the detection of fluoride level in water, and the prevalence of dental fluorosis in children aged 8 to 12 in all affected villages of 11 leagues (cities) in the entire autonomous region. The prevention and control effect of drinking water-borne endemic fluorosis in the entire autonomous region was evaluated.Results:The water improvement rates of all affected villages in the entire autonomous region in 2015 and 2023 were 84.12% (8 218/9 769) and 95.38% (8 944/9 377), respectively. The qualified rates of water fluoride in the villages with water improvement in the entire autonomous region were 66.21% (5 441/8 218) and 91.00% (8 139/8 944), respectively. The water improvement rate and water fluoride qualification rate of water improvement villages in 2023 were both higher than those in 2015, and the differences were statistically significant (χ 2 = 652.96, 1 593.81, P < 0.001). The detection rates of dental fluorosis in children aged 8 to 12 years in the entire autonomous region in 2015 and 2023 were 9.26% (7 548/81 484) and 4.46% (3 441/77 155), respectively. The detection rate of dental fluorosis in children in 2023 was lower than that in 2015, and the difference was statistically significant (χ 2 = 1 418.20, P < 0.001). In 2015 and 2023, the total compliance rate of all affected villages in the entire autonomous region reaching the control standards were 57.94% (5 660/ 9 769) and 92.37% (8 662/9 377), respectively. The total compliance rate of all affected villages in 2023 was higher than that in 2015, and the difference was statistically significant (χ 2 = 3 010.38, P < 0.001). Conclusions:Compared with 2015, the prevention and control measures of drinking water-borne endemic fluorosis in Inner Mongolia Autonomous Region have been effectively implemented in 2023, with a significant decrease in the detection rate of dental fluorosis in children. However, there are still a few affected villages that have not achieved the control standards, and prevention and control work still need to be further strengthened.

Objective:To investigate the characteristics of the population of skeletal fluorosis patients in drinking-tea-borne endemic fluorosis (referred to as drinking-tea-borne fluorosis) areas in Inner Mongolia Autonomous Region (referred to as Inner Mongolia) and the influencing factors of treatment willingness, and to provide a basis for improving the prevention and control measures of drinking-tea-borne fluorosis and the treatment plan of skeletal fluorosis.Methods:From August to October 2022, a face-to-face questionnaire survey was conducted in key areas of drinking-tea-borne fluorosis in Inner Mongolia (administrative villages with an average daily intake of tea fluoride > 3.5 mg and skeletal fluorosis patients identified by the general survey of drinking-tea-borne fluorosis in Inner Mongolia in 2019), and to investigate the demographic, severity, and treatment status of patients with skeletal fluorosis, analyze the demographic characteristics of patients with skeletal fluorosis and the influencing factors of treatment willingness.Results:A total of 734 patients with skeletal fluorosis were investigated, including 543 mild cases, 125 moderate cases and 66 severe cases. The gender ratio of patients with skeletal fluorosis was 0.71 ∶ 1.00 (305/429), the age was concentrated in > 50 - 70 years old (70.57%, 518/734), the proportion of Mongolians was 94.28% (692/734), the proportion of herders was 97.68% (717/734), the educational level was mainly primary school (54.63%, 401/734), and the proportion of poor households and immigrants who had moved to their current residence was 7.08% (52/734) and 8.04% (59/734), respectively. The distribution of the severity of skeletal fluorosis in patients of different ages, genders, and educational levels was compared, and the differences were statistically significant ( P < 0.05). Fifty-three point two seven percent (391/734) of the patients had a willingness to undergo non-pharmacological treatment, of which 69.82% (273/391) had already started non-pharmacological treatment, with a treatment effectiveness rate of 73.99% (202/273). Sixty-five point two six percent (479/734) of the patients had a willingness to receive medication treatment, of which 7.31% (35/479) had already started medication treatment, with a treatment effectiveness rate of 54.29% (19/35). Zero point two seven percent (2/734) of the patients expressed a willingness to undergo surgical treatment, while no patients underwent surgical treatment. Multivariate logistic regression analysis showed that the age, ethnicity, occupation, educational level, poverty status, immigrants status, and the severity of skeletal fluorosis were all influencing factors of non-pharmacological treatment willingness ( P < 0.05). Occupation, educational level, poverty status, immigrants status, and the severity of skeletal fluorosis were all influencing factors of medication treatment willingness ( P < 0.05). Conclusions:Patients with skeletal fluorosis caused by tea drinking in Inner Mongolia are mainly from Mongolian ethnic groups, herders, middle-aged and elderly people, and those with a lower educational levels. The willingness of patients to receive treatment is influenced by various factors, and corresponding intervention measures can be formulated and taken based on these influencing factors to effectively improve the disease prevention awareness and treatment willingness of patients and the public.

Objective To observe the value of T1WI deep learning models for evaluating brain injury of neonatal hyperbilirubinemia(NHB).Methods Totally 106 NHB(defined as newborns with neonatal behavioral neurological assessment≤37,NHB group)and 119 non-NHB newborns(control group)in center A,as well as 34 NHB and 18 non-NHB newborns in center B were collected.ROI was delineated based on bilateral globus pallidus on T1WI.A total of 690 slices were obtained by preprocessing data of center A and then were divided into training set(n=552)and test set(n=138)at a ratio of 8∶2.ResNet18,DenseNet121 and EfficientNetB0 models was established,respectively.External validation was performed based on data of center B.Receiver operating characteristic curves were drawn,area under the curves(AUC)were calculated to evaluate the performance of models for assessing NHB brain injuries compared with traditional visual analysis.Results The AUC of ResNet18 model for evaluating NHB brain injury was 0.910-0.990,significantly higher than that of DenseNet121 model(0.710-0.820)and EfficientNetB0 model(0.640-0.740)(all P＜0.001).The accuracy,sensitivity and precision of ResNet18 model for evaluating NHB brain injury were all higher than those of visual analysis(all P＜0.05),while no significant difference of specificity was found between the above two(P＞0.05).Conclusion T1WI ResNet18 model showed excellent performance and generalization ability for evaluating NHB brain injury.

To explore the application effect of host restriction factors(HRFs)in the development of antiviral gene drugs,this study based on the"common pathway of viral infection"and"host innate immunity HRFs",the genes of three antiviral HRFs,namely cholesterol-25-hydroxylase(CH25H),interferon-induced transmembrane protein(IFITM3)and interferon-stimulated gene 15(ISG15)were fused and expressed using pCK vectors to construct antiviral gene drugs.The fusion expression gene sequence CH25H-IFITM3-ISG15(C Ⅱ)was constructed by linking the gene cod-ing sequences of these three HRFs through the cleavage peptide coding sequence.Subsequently,the C Ⅱ sequence was amplified by PCR,ligated to the pCK expression vector,and the recombinant plasmid was transformed,identified,and extracted to obtain a candidate biodrug based on the DNA expression system,which was named pCK-CⅡ.Then,the recombinant plasmid was transfected in-to HEK 293T cells,and the expression of three antiviral proteins was successfully detected by Western blot.To clarify the antiviral effect of pCK-C Ⅱ at the cellular level,pCK-C Ⅱ was trans-fected into HEK 293 cells and BHK-21 cells,respectively.Twenty-four hours later,the BHK-21 cells were infected with vesicular stomatitis virus expressing green fluorescent protein(VSV-GFP),12 h later,the cells were observed under a fluorescence microscope and detected by flow cy-tometry;HEK 293 cells were inoculated with H3N2 subtype influenza virus,and the expression of H3N2 subtype influenza virus nuclear proteins was detected after 12 h using Western blot.The re-sults showed that transient transfection of pCK-C Ⅱ plasmid could significantly reduce the fluores-cence level of cells and the expression of nuclear protein of H3N2 subtype influenza virus in infec-ted cells.These results indicated that pCK-C Ⅱ had an inhibitory effect on the infection of VSV-GFP and H3N2 subtypes of influenza viruses after transient transfection of cells.
