Guided by Academician Zhang Boli's theory of "dampness, turbidity, phlegm, and fluid-related diseases",this paper elaborated on the pathogenesis and syndrome differentiation treatment of heart failure from the perspective of the "spleen-mitochondria". It analyzed the essential similarities between "spleen-mitochondria" and "dampness, turbidity, phlegm, and fluid-related diseases", as well as their close association with the onset of heart failure. Furthermore,it explored the connection between spleen function and mitochondrial function in traditional Chinese medicine (TCM),positing that the spleen's role in transportation and transformation is analogous to mitochondrial material metabolism and energy conversion,with spleen deficiency closely related to mitochondrial dysfunction. It thus concluded that mitochondrial material metabolism and energy conversion represent the microscopic essence of the spleen's role in transportation and transformation,and mitochondrial dysfunction is a contributing factor to pathological products like dampness and turbid phlegm,which are closely associated with the occurrence of heart failure. The four elements of dampness,turbidity,phlegm,and fluid are a series of related symptoms resulting from abnormal fluid transportation and transformation,serving as both factors in the onset of heart failure and the core pathological basis for its deterioration. Therefore,during the treatment of heart failure,it is essential to regulate mitochondrial function. Early intervention should focus on eliminating dampness and turbidity to improve mitochondrial function and restore normal energy metabolism. In the middle and late stages,emphasis should be placed on resolving phlegm,promoting blood circulation,warming Yang,and reducing water retention to alleviate mitochondrial damage and improve cardiac function. Supporting Qi and strengthening the spleen should be a continuous approach,and treatment should be adjusted to enhance mitochondrial function and stabilize the condition,thereby improving prognosis. This paper discussed the role of the spleen and mitochondria in the pathogenesis of heart failure,examined the evolution of heart failure mechanisms from the perspective of dampness, turbidity, phlegm, and fluid-related diseases,and proposed a phased treatment strategy. It enriched the theory of dampness, turbidity, phlegm, and fluid-related diseases and offered new strategies for heart failure treatment. However,in practical application,TCM strategies for treating heart failure need to be integrated with modern medical approaches to provide a more solid scientific foundation for treatment.

Objective To investigate the factors affecting the distribution of Pomacea and project the trends in the spread of suitable distribution areas of Pomacea in 2050 and 2070 in Dali Bai Autonomous Prefecture, so as to provide insights into Pomacea control in the prefecture. Methods The longitudes and latitudes of Pomacea sampling sites were captured based on Pomacea field survey data in 12 cities (counties) of Dali Bai Autonomous Prefecture from 2023 to 2024. A total of 19 climatic factors (annual mean temperature, mean diurnal range, isothermality, temperature seasonality, maximum temperature of the warmest month, minimum temperature of the coldest month, temperature annual range, mean temperature of the wettest quarter, mean temperature of the driest quarter, mean temperature of the warmest month, mean temperature of the coldest month, annual precipitation, precipitation of the wettest month, precipitation of the driest month, precipitation seasonality, precipitation of the wettest quarter, precipitation of the driest quarter, mean temperature of the warmest quarter, and mean temperature of the coldest quarter) and representative concentration pathways (RCPs) were retrieved from the world climate database (www.worldclim.org). All climatic variables were employed to create a maximum entropy (MaxEnt) model. The predictive accuracy of the model was assessed with the area under the receiver operating characteristic (ROC) curve (AUC), and the contributions of these 19 climatic factors to the distribution of Pomacea were analyzed in Dali Bai Autonomous Prefecture using Jackknife test. In addition, the suitable distribution areas of Pomacea were predicted with the MaxEnt model in Dali Bai Autonomous Prefecture in 2024 and in 2050 and 2070 under RCP4.5. Results Data pertaining to 91 Pomacea sampling sites were captured. ROC analysis revealed the MaxEnt model had an AUC value of 0.885 ± 0.088 for predicting the suitable distribution areas of Pomacea in Dali Bai Autonomous Prefecture. Of the 19 climatic factors, the maximum temperature of the warmest month had the highest contribution to the distribution of Pomacea in Dali Bai Autonomous Prefecture, followed by mean temperature of the driest quarter, mean temperature of the wettest quarter and minimum temperature of the coldest month. The suitable distribution area of Pomacea was predicted to be 14 555.69 km2 in Dali Bai Autonomous Prefecture in 2024, and would expand gradually to the southeastern part of the prefecture in the future due to climatic factors. The suitable distribution areas of Pomacea were projected to expand to 21 475.61 km2 in 2050 and 25 782.52 km2 in 2070 in Dali Bai Autonomous Prefecture, respectively. Conclusions Temperature is an important contributor to the distribution of Pomacea in Dali Bai Autonomous Prefecture, and the suitable distribution area of Pomacea will gradually expand to the southeastern part of the prefecture in 2050 and 2070.

Ferroptosis, a programmed cell death modality discovered and defined in the last decade, is primarily induced by iron-dependent lipid peroxidation. At present, it has been found that ferroptosis is involved in various physiological functions such as immune regulation, growth and development, aging, and tumor suppression. Especially its role in tumor biology has attracted extensive attention and research. Breast cancer is one of the most common female tumors, characterized by high heterogeneity and complex genetic background. Triple negative breast cancer (TNBC) is a special type of breast cancer, which lacks conventional breast cancer treatment targets and is prone to drug resistance to existing chemotherapy drugs and has a low cure rate after progression and metastasis. There is an urgent need to find new targets or develop new drugs. With the increase of studies on promoting ferroptosis in breast cancer, it has gradually attracted attention as a treatment strategy for breast cancer. Some studies have found that certain compounds and natural products can act on TNBC, promote their ferroptosis, inhibit cancer cells proliferation, enhance sensitivity to radiotherapy, and improve resistance to chemotherapy drugs. To promote the study of ferroptosis in TNBC, this article summarized and reviewed the compounds and natural products that induce ferroptosis in TNBC and their mechanisms of action. We started with the exploration of the pathways of ferroptosis, with particular attention to the System Xc--cystine-GPX4 pathway and iron metabolism. Then, a series of compounds, including sulfasalazine (SAS), metformin, and statins, were described in terms of how they interact with cells to deplete glutathione (GSH), thereby inhibiting the activity of glutathione peroxidase 4 (GPX4) and preventing the production of lipid peroxidases. The disruption of the cellular defense against oxidative stress ultimately results in the death of TNBC cells. We have also our focus to the realm of natural products, exploring the therapeutic potential of traditional Chinese medicine extracts for TNBC. These herbal extracts exhibit multi-target effects and good safety, and have shown promising capabilities in inducing ferroptosis in TNBC cells. We believe that further exploration and characterization of these natural compounds could lead to the development of a new generation of cancer therapeutics. In addition to traditional chemotherapy, we discussed the role of drug delivery systems in enhancing the efficacy and reducing the toxicity of ferroptosis inducers. Nanoparticles such as exosomes and metal-organic frameworks (MOFs) can improve the solubility and bioavailability of these compounds, thereby expanding their therapeutic potential while minimizing systemic side effects. Although preclinical data on ferroptosis inducers are relatively robust, their translation into clinical practice remains in its early stages. We also emphasize the urgent need for more in-depth and comprehensive research to understand the complex mechanisms of ferroptosis in TNBC. This is crucial for the rational design and development of clinical trials, as well as for leveraging ferroptosis to improve patient outcomes. Hoping the above summarize and review could provide references for the research and development of lead compounds for the treatment for TNBC.

ObjectiveGliomas in the motor functional area can damage the corticospinal tract (CST), leading to motor dysfunction. Currently, there is a lack of unified methods for evaluating the extent of CST damage, especially in patients with high surgical risk where the minimum distance from the lesion to the CST is less than 10 mm. This study aims to further clarify the classification method and clinical significance of CST morphological changes in these patients. MethodsThis retrospective study analyzed 109 high-risk functional area glioma patients who underwent neurosurgical treatment with preoperative diffusion tensor imaging (DTI) imaging and intraoperative neurostimulation guidance between 2014 and 2024. All patients had a lesion-to-tract distance (LTD) of less than 10 mm between the CST and the lesion. Preoperative DTI evaluation of CST involvement-induced morphological changes were reviewed. Patients were divided into 3 groups: 17 cases (15.6%) with symmetric CST morphology compared to the healthy side (CST symmetry), 48 cases (44.0%) with significant CST morphology changes compared to the healthy side (CST deformation), and 44 cases (40.4%) with CST overlap with the tumor (CST overlap). Then we classified patients according to preoperative assessment of tumor-induced morphological changes, and analyze postoperative motor function for each category. ResultsPostoperative pathology showed a significantly higher proportion of high-grade gliomas (HGG) in the CST overlap group compared to the other two groups (P=0.001). Logistic regression analysis showed that CST overlap was a predictor of HGG (P=0.000). The rate of total tumor resection in the CST deformation group and overlap group was lower than in the CST symmetric group (P=0.008). There was a total of 41 postoperative hemiplegic patients, with 4 cases (23.5%) in the CST symmetric group, 11 cases (22.9%) in the CST deformation group, and 26 cases (59.1%) in the CST overlap group. CST overlap with the tumor predicted postoperative hemiplegia (P=0.016). Two-way ANOVA analysis of the affected/healthy side and CST morphology groups showed significant main effects of CST grouping and healthy-affected side (P=0.017 and P=0.010), with no significant interaction (P=0.31). The fractional anisotropy (FA) value in the CST overlap group and the affected side was lower. A decrease in the FA value on the affected side predicted postoperative hemiplegia (sensitivity 69.2%, specificity 71.9%). ConclusionWe have established a method to predict postoperative hemiplegia in high-risk motor functional area glioma patients based on preoperative CST morphological changes. CST overlap leads to a decrease in CST FA values. This method can be used for precise patient management and aid in accurate preoperative surgical planning.

Growth and development-related diseases result from the interplay of biological, psychological, and social factors. The collaboration between healthcare, sports, and education sectors integrates multidisciplinary resources and strengths to promote standardized diagnostic and therapeutic processes. This approach establishes a comprehensive closed-loop system encompassing early screening and referral, diagnosis and comprehensive evaluation, intervention and support plan formulation, as well as long-term management andoutcome assessment. It provides systematic scientific support for the healthy growth of children and adolescents, shifting disease intervention to the subclinical stage. Against the backdrop of societal informatization and intelligent development, this diagnostic and therapeutic model not only safeguards the holistic health of children and adolescents but also offers novel perspectives and feasible pathways for managing growth and development-related diseases. The implementation of this systematic diagnostic and therapeutic paradigm presents an innovative solution with Chinese characteristics for addressing such conditions, while injecting new vitality into the advancement of national health initiatives.

To investigate the prevalence and associated factors of fall risk among Chinese older adults, and to examine the roles of urban-rural differences, regional disparities, physical health status, and psychosocial factors in falls among this population, thereby providing evidence for tailored fall prevention strategies. Using data from the 2024 National Routine Physical Fitness Surveillance, a multi-stage stratified sampling method was employed to recruit community-dwelling older adults aged 60-79 years across China. High fall-risk individuals were identified using the Chinese version of the self-rated fall risk questionnaire, while demographic, physical health, and psychological indicators were collected via questionnaires and objective measurements. A generalized linear mixed model (GLMM) with province as a random effect was used to analyze fall risk factors. Among 7000 eligible participants (male: 44.2%, female: 55.8%), the sample comprised 2124 (60-64 years), 2014 (65-69 years), 1660 (70-74 years), and 1202 (75-79 years) individuals, with 58.4% from rural and 41.6% from urban areas. A total of 733(10.5%) were identified as high fall-risk, with higher prevalence among females (10.9%), urban residents (11.5%), and the oldest age group (75-79 years: 12.4%). GLMM random-intercept logistic regression revealed that advanced age ( The prevalence of high fall risk among Chinese community-dwelling older adults aged 60-79 years is 10.5%. Fall risk demonstrates significant associations with multiple factors including muscle strength, movement patterns, sleep quality, and social support. Strategies enhancing grip strength, promoting regular exercise and high-intensity leisure activities, improving sleep quality, fostering spousal support, and boosting life satisfaction may substantially reduce fall risk in this population.

Based on the data from the 5th National Physical Fitness Surveillance in China, this study aimed to explore the relationship between abnormal body weight and physical fitness levels in older adults. The study included adults aged 60-79 years from the 5th National Physical Fitness Surveillance database. Body weight was categorized into four groups—underweight, normal weight, overweight, and obesity—based on body mass index (BMI), with underweight, overweight, and obesity classified as abnormal weight. Physical fitness indicators such as cardiorespiratory endurance (number of 2-minute high-knee steps), lower limb muscle strength (number of 30-second chair stands), flexibility (sit-and-reach test), balance ability (eyes-closed single-leg stance time), and reaction ability (choice reaction time) were collected. Each physical fitness indicator was divided into four levels (excellent, good, pass, and fail) based on quartile cutoffs. After adjusting for demographic factors (including age, sex, urban/rural residence, education level, pre-retirement occupation, marital status, exercise habits, smoking, sleep quality, and self-rated fitness), binary Logistic regression was used to analyze the association between physical fitness indicators and abnormal weight. A total of 39 927 older adults aged 60-79 years were included, comprising 19 777 men (49.5%) and 20 150 women (50.5%), with a mean age of 69.2±5.6 years. The prevalence rates of underweight, overweight, and obesity were 2.3%, 41.8%, and 16.7%, respectively, with underweight prevalence significantly increasing with age ( Chinese older adults aged 60-79 years face a dual burden of underweight and overweight/obesity. Poor cardiorespiratory endurance and muscle strength (in women) are significantly associated with abnormal weight. Maintaining good cardiorespiratory endurance and muscle strength may help improve abnormal weight status in older adults.

To explore the dose-response correlation between appendicular skeletal muscle index (ASMI) and muscle strength in older adults. This study included adults aged 60-79 years from the 2024 National Routine Physical Fitness Surveillance database. ASMI was used to assess muscle mass, while handgrip strength and 30-second chair stand test (30-s CST) repetitions were employed to evaluate muscle strength. Linear regression analyses, adjusted for age and body mass index (BMI), were performed to examine the associations between ASMI and handgrip strength/30-s CST. Additionally, restricted cubic spline (RCS) models were applied for dose-response analysis. A total of 68 038 older adults (56.3% female, mean age 68.0±5.4 years) were included. Males exhibited significantly higher handgrip strength(33.6± 7.8 kg s Muscle mass and strength are significantly positively correlated in older adults. Personalized muscle health interventions should be considered to reduce the rate of decline in muscle strength, when ASMI falls below 13.55 kg/m2 in men or 11.25 kg/m2 in women.

Objective: To investigate the distribution characteristics of CD36 antigen in healthy individuals in Xinjiang, China and analyze the molecular mechanisms underlying CD36 deficiency. Methods: Flow cytometry was used to assess CD36 antigen expression on platelets from 881 healthy individuals who underwent physical examinations between June and August 2023. Differences in CD36 antigen distribution among ethnic groups were compared, and genotyping and third-generation sequencing were conducted on samples with CD36 deficiency. Results: Among the 881 samples, 4 cases (0.5%) of CD36 type Ⅱ deficiency were identified. The deficiency frequency was 0.7% (3/430) in Han individuals and 0.3% (1/363) in Uygur individuals, with no statistically significant difference between the two groups (P>0.05). No mutations were detected in the coding regions of the deficient samples. Two samples exhibited a (TG)11 in intron 3. Among the 12 linked mutation sites, g. 55589 G>A was mutated to g. 55589G Del, while g. 55593 A del did not occur; however, g. 55591A>T was observed nearby. Additionally, 52742insGAAAA was present in 100% of the (TG)11 haplotypes, potentially representing a novel linked mutation. Conclusion: This study indicates that the positive frequency of CD36 antigen in Xinjiang is relatively high, suggesting a low risk of alloimmune diseases in clinical practice. The (TG)11 in intron 3 is not universally present in all CD36 type Ⅱ deficiency cases, and the number of linked mutation sites extends beyond the previously reported 12.
