The accumulation of uremic toxins such as urea nitrogen, blood creatinine, and uric acid of patients with renal failure in vivo would lead to aggravated kidney damage. In this study, coated aldehyde oxy-starch (CAO) was used as an adsorbent to investigate its in vitro adsorption performance on renal failure indexes for urea, indoxyl sulfate (INS), monomethylamine (MMA), dimethylamine (DMA), uric acid (UA), and creatinine (Cr). The effects of variables such as pH, temperature, concentration, dosage, and time on the adsorption capacity of CAO were systematically investigated, employing analytical techniques of high-performance liquid chromatography (HPLC) and gas chromatography (GC). The results revealed that CAO exhibited a strong adsorption capacity for urea, INS, and MMA, alongside a moderate adsorption capacity for DMA, UA, and Cr. The adsorption kinetics and thermodynamic studies indicated that the adsorption of urea and UA by CAO were fitted in pseudo-first-order kinetics, and the adsorption isotherm aligned with the Freundlich adsorption model. The enthalpy change ΔH of urea in adsorption was in the range of 40 to 60 kJ·mol^-1, which demonstrated the presence of strong adsorption force due to the interactions of coordinating groups. The ΔH of UA was greater than 80 kJ·mol^-1, indicating the generation of chemical bonds during the adsorption. Both of them, Gibbs free energy ΔG was less than 0, within the range of -20 to 0 kJ·mol^-1, suggested that the adsorption of urea and UA by CAO occurred spontaneously as physical adsorption process. The adsorption entropy ΔS of urea and UA was > 0, which indicated an increase in entropy throughout the adsorption. The infrared spectroscopygram showed the formation of a chemical bond, specifically the imine bond, following the adsorption of urea by CAO, thereby indicating a chemical reaction during the adsorption. This study elucidates the adsorption mechanism of CAO on various indexes of renal failure, providing a scientific basis for its clinical usage.

Cardiovascular disease (CVD), chronic kidney disease (CKD), and metabolic disorders are the 3 major chronic diseases threatening human health, which are closely related and often coexist, significantly increasing the difficulty of disease management. In response, the American Heart Association (AHA) proposed a novel disease concept of “cardiovascular-kidney-metabolic (CKM) syndrome” in October 2023, which has triggered widespread concern about the co-treatment of heart and kidney diseases and the prevention and treatment of metabolic disorders around the world. This review posits that effectively managing CKM syndrome requires a new and multidimensional paradigm for diagnosis and risk prediction that integrates biological insights, advanced technology and social determinants of health (SDoH). We argue that the core pathological driver is a “metabolic toxic environment”, fueled by adipose tissue dysfunction and characterized by a vicious cycle of systemic inflammation and oxidative stress, which forms a common pathway to multi-organ injury. The at-risk population is defined not only by biological characteristics but also significantly impacted by adverse SDoH, which can elevate the risk of advanced CKM by a factor of 1.18 to 3.50, underscoring the critical need for equity in screening and care strategies. This review systematically charts the progression of diagnostic technologies. In diagnostics, we highlight a crucial shift from single-marker assessments to comprehensive multi-marker panels. The synergistic application of traditional biomarkers like NT-proBNP (reflecting cardiac stress) and UACR (indicating kidney damage) with emerging indicators such as systemic immune-inflammation index (SII) and Klotho protein facilitates a holistic evaluation of multi-organ health. Furthermore, this paper explores the pivotal role of non-invasive monitoring technologies in detecting subclinical disease. Techniques like multi-wavelength photoplethysmography (PPG) and impedance cardiography (ICG) provide a real-time window into microcirculatory and hemodynamic status, enabling the identification of early, often asymptomatic, functional abnormalities that precede overt organ failure. In imaging, progress is marked by a move towards precise, quantitative evaluation, exemplified by artificial intelligence-powered quantitative computed tomography (AI-QCT). By integrating AI-QCT with clinical risk factors, the predictive accuracy for cardiovascular events within 6 months significantly improves, with the area under the curve (AUC) increasing from 0.637 to 0.688, demonstrating its potential for reclassifying risk in CKM stage 3. In the domain of risk prediction, we trace the evolution from traditional statistical tools to next-generation models. The new PREVENT equation represents a major advancement by incorporating key kidney function markers (eGFR, UACR), which can enhance the detection rate of CKD in primary care by 20%-30%. However, we contend that the future lies in dynamic, machine learning-based models. Algorithms such as XGBoost have achieved an AUC of 0.82 for predicting 365-day cardiovascular events, while deep learning models like KFDeep have demonstrated exceptional performance in predicting kidney failure risk with an AUC of 0.946. Unlike static calculators, these AI-driven tools can process complex, multimodal data and continuously update risk profiles, paving the way for truly personalized and proactive medicine. In conclusion, this review advocates for a paradigm shift toward a holistic and technologically advanced framework for CKM management. Future efforts must focus on the deep integration of multimodal data, the development of novel AI-driven biomarkers, the implementation of refined SDoH-informed interventions, and the promotion of interdisciplinary collaboration to construct an efficient, equitable, and effective system for CKM screening and intervention.

OBJECTIVE: To observe the effectiveness and safety of Huotujiji prescription for patients with asthenospermia of spleen-kidney yang-deficiency. METHODS: Patients with spleen-kidney-yang deficiency type of asthenospermia were divided into two groups by randomized control method. The patients in the control group were treated with L-carnitine oral solution alone. And the patients in experimental group were treated with Huotujiji prescription. Semen volume, sperm concentration, PR, TCM symptom score and spouse pregnancy were compared between the two groups before and after treatment. RESULTS: A total of 115 patients were included in the study, with 55 in the experimental group and 60 in the control group. In the experimental group, the sperm concentration before and after treatment were (160.71±53.7)×106/mL, (187.19±41.89)×106/mL, and PR were (20.37±9.42)%, (26.7±6.92)%, respectively. PR+NP were (32.06±8.49)% and (34.89±7.25)%. After the treatment, the sperm motility of both groups significantly improved compared to pre-treatment levels (P<0.05). And the experimental group's sperm concentration also showed a significant increase after the treatment (P<0.05). The pregnancy rate of spouses in the control group was 11.67%, which was 29.09% in the experimental group. The pregnancy rate of the spouses in the two groups showed a statistically significant difference (P<0.05). After 12weeks of treatment, the Traditional Chinese Medicine (TCM) symptom scores in the control group did not decrease significantly compared to those before treatment (P> 0.05). In contrast, the TCM symptom scores in the experimental group decreased significantly after treatment (P<0.05). Moreover, compared with the control group, the TCM symptom scores of the experimental group decreased significantly after treatment (P<0.05). CONCLUSION Huotujiji prescription can safely and effectively improve the sperm quality and vitality of patients with spleen-kidney-yang deficiency type of asthenospermia, improve the symptoms of patients, and increase the pregnancy rate of their spouses, which is worthy of clinical promotion.

OBJECTIVE To investigate the potential mechanism of the effect of ginkgo flavone aglycone （GA） against doxorubicin （DOX）-induced cardiotoxicity. METHODS The male ICR mice were randomized into control group （CON group）， model group （DOX group） and GA+DOX group （GDOX group）， with 12 mice in each group. The DOX group was injected with DOX solution at a dose of 3 mg/kg via tail vein every other day， and the GDOX group was given GA suspension intragastrically at a dose of 100 mg/kg every day+DOX solution at a dose of 3 mg/kg via tail vein every other day， for 15 consecutive days. After the end of administration， the serum levels of aspartate aminotransferase（AST）， creatine kinase（CK）， creatine kinase isoenzyme（CK- MB） and lactate dehydrogenase（LDH） in mice were detected in each group. Based on the metabolomics method， UHPLC-Q- Exactive Orbitrap HRMS method was used； based on principal component analysis （PCA） and orthogonal partial least squares- discriminant analysis （OPLS-DA）， the differentially expressed metabolites （DEMs） were screened using the criteria of variable importance in the projection≥1， fold change of peak area＞1 and P＜0.05； biological analysis was conducted based on databases such as HMDB and PubChem. RESULTS Compared with CON group， serum levels of AST， CK， CK-MB and LDH were increased significantly in DOX group （P＜0.05）； compared with DOX group， the serum levels of the above indicators （except for CK-MB） were decreased significantly in GDOX group （P＜0.05）. PCA and OPLS-DA showed that myocardial tissue samples of CON group， DOX group and GDOX group were isolated completely. After database matching， 37 common DEMs were identified， among which 17 DEMs were significantly up-regulated in the DOX group and significantly down- regulated in the GDOX group， and 8 DEMs were significantly down-regulated in the DOX group and significantly up-regulated in the GDOX group； pathway enrichment involved the biosynthesis of unsaturated fatty acids， arachidonic acid metabolism， linoleic acid metabolism， taurine and hypotaurine metabolism； the key metabolites in the above pathways included docosahexaenoic acid， arachidonic acid， phosphatidylcholine （16∶0/18∶3） and taurine. CONCLUSIONS GA may regulate the biosynthesis of unsaturated fatty acids， arachidonic acid metabolism and other metabolic pathways by acting on the core metabolites such as docosahexaenoic acid and arachidonic acid， thus alleviating the cardiotoxic effects of DOX.

ObjectiveTo conduct comprehensive assessment of internal and external cadmium exposure and health risks for Shanghai residents. MethodsCadmium levels in food samples were calculated by employing two dietary exposure assessment methods， total diet study （TDS） and food frequency questionnaire （FFQ）， to estimate the daily dietary cadmium exposure of Shanghai residents. The provisional tolerable monthly intake （PTMI） of cadmium set by joint food and agriculture organization/WHO expert committee on food additives （JECFA） was applied to evaluate the health risk. Differences in dietary and urinary cadmium were compared by rank-sum test among different regions， age， gender， smoking status， and BMI groups， and the association between internal and external cadmium exposure was investigated by correlation analysis. ResultsThe mean value of urinary cadmium for 1 300 respondents was 0.542 μg·L^-1. Urinary cadmium was higher in the population in central urban and urban-rural fringe areas than in the suburban area， higher in the older age group than in the younger age group， and higher in the smoking group than in the non-smoking group （all P<0.01）. The two assessment methods showed that the mean values of daily dietary cadmium exposure for Shanghai residents were 0.306 and 0.090 μg·kg^-1， with 3.69% and 0.85% of Shanghai residents exceeding the PTMI， respectively. Correlation analyses showed that dietary exposure to cadmium based on the FFQ method was positively correlated with the urinary cadmium level when smoking status， age， gender， and BMI were adjusted. ConclusionDietary exposure to cadmium of Shanghai residents is mainly derived from vegetables， aquatic products， cereals and potatoes， and is overall at a low-risk level. Dietary exposure assessment based on FFQ and risk monitoring data can effectively estimate long-term cadmium exposure.

Objective The aim of this study is to analyze the prevalence of depression and anxiety symptoms and its relationship with the socio-economic position(SEP)among the elderly people in Dai rural areas of Jinggu County,Yunnan province.Methods A multi-stage stratified random sampling method was used to conduct a questionnaire survey among 1409 people aged 60 and over in Dai rural areas of Jinggu County,Yunnan Province.The individual SEP index was constructed using the principal component analysis.Results The prevalence of anxiety symptoms,depression symptoms,and mixed anxiety-depressive disorder symptoms was 4.8%,52.0%,and 4.2% among them,2.6%,49.4%,and 2.3% among the males,and 6.8%,54.5%,and 6.0% among the females respectively.Females had the higher prevalence of anxiety symptoms and mixed anxiety-depressive disorder symptoms than males(P<0.05).Elderly people with the higher level of education,annual per capita household income and SEP had the lower prevalence of anxiety symptoms and mixed anxiety-depressive disorder symptoms than their counterparts(both P<0.05).The prevalence of depression symptoms increased with age(P<0.01).The difference in the prevelence of depression symptoms among the elderly people with the different numbers of chronic conditions was statistically significant(P<0.01).The results of multivariate logistic regression analysis showed that the elderly people with lower SEP were more likely to suffer from the anxiety symptoms(OR=0.707,95% CI:0.566～0.883),depression symptoms(OR=0.492,95% CI:0.438～0.552),and mixed anxiety-depressive disorder symptoms(OR=0.602,95% CI:0.469～0.773).Conclusion There are significant socio-economic differences in the prevalence of anxiety symptoms and depression symptoms among the elderly people in Dai rural areas of Jinggu County,Yunnan province.Future mental health interventions should more focus on females,elderly people with advanced age,multiple chronic diseases and low SEP,so as to reduce the occurrence of depression symptoms and anxiety symptoms.

Objective This study aimed to explore the differences in global and local brain network topological properties between deficient pattern(DP)and excess pattern(EP)of mild vascular cognitive impairment caused by subcortical small vessel disease based on graph theory network.Methods Patients were recruited prospectively and were classified with DP and EP subtype.The global small-world topological attributes and local nodes were calculated for the comparison of DP,EP,and healthy controls(CN)using the GRETNA platform.Results The three groups all had small-world attributes,but only the patients in EP had a significantly lower small world attribute δ in the range of 0.05-0.26 than the control group(P<0.05).The node efficiency and node strength indicators of multiple brain region were able to significantly distinguish the DP group from the EP group.However,there was no positive brain region in the node efficiency of the DP patients(P>0.05),and only a few brain regions showed increased node strength efficiency(P<0.05).Conclusion The results indicate that the syndrome of DP and EP have significantly different neuroimaging phenotypes,providing a basis for further research of biological classification based on Chinese Medicine syndromes.
