With the development of neuroscience and oncology, the direct regulation effect of central nervous system circuits on tumors has been gradually revealed. Evidence indicates that the therapy targeting emotion-related encephalic regions may have great potential in blocking the promotion of breast cancer progression by depression. The underlying complex mechanisms involve the generation of depression and the regulation of tumors by central nervous system circuits. However, a systematic summary is lacking in this field. This article reviews the latest research progress of the central nervous system circuits and the generation of depression, the neural connection between the central nervous system and peripheral tumor, and the regulation of the tumor immune microenvironment by the sympathetic nervous system. It also systematically investigates the potential mechanism of the central nervous system circuit in the promotion of breast cancer progression by depression to establish new solutions for the comprehensive treatment of breast cancer.

Objective To evaluate the predictive ability and clinical application value of artificial intelligence (AI) systems in the benign and malignant differentiation and pathological type of pulmonary nodules, and to summarize clinical application experience. Methods A retrospective analysis was conducted on the clinical data of patients with pulmonary nodules admitted to the Department of Thoracic Surgery, Second Hospital of Lanzhou University, from February 2016 to February 2025. Firstly, pulmonary nodules were divided into benign and non-benign groups, and the discriminative abilities of AI systems and clinicians were compared. Subsequently, lung nodules reported as precursor glandular lesions (PGL), microinvasive adenocarcinoma (MIA), and invasive adenocarcinoma (IAC) in postoperative pathological results were analyzed, comparing the efficacy of AI systems and clinicians in predicting the pathological type of pulmonary nodules. Results In the analysis of benign/non-benign pulmonary nodules, clinical data from a total of 638 patients with pulmonary nodules were included, of which there were 257 males (10 patients and 1 patient of double and triple primary lesions, respectively) and 381 females (18 patients and 1 patient of double and triple primary lesions, respectively), with a median age of 55.0 (47.0, 61.0) years. Different lesions in the same patient were analyzed as independent samples. Univariate analysis of the two groups of variables showed that, except for nodule location, the differences in the remaining variables were statistically significant (P<0.05). Multivariate logistic regression analysis showed that age, nodule type (subsolid pulmonary nodule), average density, spicule sign, and vascular convergence sign were independent influencing factors for non-benign pulmonary nodules, among which age, nodule type (subsolid pulmonary nodule), spicule sign, and vascular convergence sign were positively correlated with non-benign pulmonary nodules, while average density was negatively correlated with the occurrence of non-benign pulmonary nodules. The area under the receiver operating characteristic curve (AUC) of the malignancy risk value given by the AI system in predicting non-benign pulmonary nodules was 0.811, slightly lower than the 0.898 predicted by clinicians. In the PGL/MIA/IAC analysis, clinical data from a total of 411 patients with pulmonary nodules were included, of which there were 149 males (8 patients of double primary lesions) and 262 females (17 patients of double primary lesions), with a median age of 56.0 (50.0, 61.0) years. Different lesions in the same patient were analyzed as independent samples. Univariate analysis results showed that, except for gender, nodule location, and vascular convergence sign, the differences in the remaining variables among the three groups of PGL, MIA, and IAC patients were statistically significant (P<0.05). Multinomial multivariate logistic regression analysis showed that the differences between the parameters in the PGL group and the MIA group were not statistically significant (P>0.05), and the maximum diameter and average density of the nodules were statistically different between the PGL and IAC groups (P<0.05), and were positively correlated with the occurrence of IAC as independent risk factors. The average AUC value, accuracy, recall rate, and F1 score of the AI system in predicting lung nodule pathological type were 0.807, 74.3%, 73.2%, and 68.5%, respectively, all better than the clinical physicians’ prediction of lung nodule pathological type indicators (0.782, 70.9%, 66.2%, and 63.7% respectively). The AUC value of the AI system in predicting IAC was 0.853, and the sensitivity, specificity, and optimal cutoff value were 0.643, 0.943, and 50.0%, respectively. Conclusion This AI system has demonstrated high clinical value in predicting the benign and malignant nature and pathological type of lung nodules, especially in predicting lung nodule pathological type, its ability has surpassed that of clinical physicians. With the optimization of algorithms and the adequate integration of multimodal data, it can better assist clinical physicians in formulating individualized diagnostic and treatment plans for patients with lung nodules.

ObjectiveTo investigate the clinical efficacy of Gandouling tablet （GDL） on abnormal lipid metabolism in Wilson's disease （WD） and the correlation between the prediction model of hepatic steatosis and the related indexes of lipid metabolism in WD. MethodA total of 86 patients with abnormal lipid metabolism in WD were selected. The 24-hour urine copper， alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， serum triglyceride （TG）， total cholesterol （TC）， apolipoprotein B （ApoB）， low density lipoprotein cholesterol （LDL-C）， bile acid （BA）， γ-glutamyl transferase （GGT）， prediction model of hepatic steatosis ［hepatic steatosis index （HSI） and Zhejiang University index （ZJU index）］， ultrasonic attenuation coefficient imaging （ATT）， and traditional Chinese medicine （TCM） syndrome score were statistically analyzed before treatment. Pearson correlation test was used to analyze the correlation between TG， TC， LDL-C， ApoB， ALT， AST， ALT/AST， BA， GGT， TCM syndrome score， ATT， and HIS and ZJU. The patients were divided into an observation group and a control group by random number table method， with 43 cases in each group. The observation group was treated with GDL combined with sodium dimercaptopropane sulfonate （DMPS）， while the control group was only treated with DMPS as a control. After six courses of treatment， 24-hour urine copper， TC， TG， LDL-C， ApoB， HSI， ZJU， ATT， TCM syndrome score， and clinical efficiency before and after treatment were observed and compared between the two groups. The correlation between HSI and ZJU and serum TC， TG， LDL-C， ApoB， ALT， AST， ALT/AST， BA， GGT， TCM syndrome scores， and ATT was analyzed. ResultPearson correlation analysis showed that serum TC （r = 0.811）， TG （r = 0.826）， LDL-C （r = 0.802）， ApoB （r = 0.820）， ALT （r = 0.497）， ALT/AST （r = 0.826）， TCM syndrome score （r = 0.716）， and ATT （r = 0.736） were positively correlated with HSI （P<0.01）， while AST， BA， and GGT had no significant correlation with HSI. TC （r = 0.718）， TG （r = 0.765）， LDL-C （r = 0.667）， ApoB （r = 0.699）， ALT/AST （r = 0.403）， TCM syndrome score （r = 0.666）， and ATT （r = 0.684） were positively correlated with ZJU （P<0.01）. ALT， AST， BA， and GGT had no significant correlation with ZJU. The total effective rate of the observation group was 86.05 （37/43）， and that of the control group was 72.09% （31/43）. The total effective rate of the observation group was higher than that of the control group （Z = -2.301， P<0.05）. After treatment， the 24-hour urine copper of the two groups increased significantly. The levels of TC， TG， LDL-C， and ApoB were significantly decreased， and the HSI， ZJU， and ATT were significantly decreased （P<0.01）. Compared with those in the control group after treatment， the above indexes improved better in the observation group （P<0.05， P<0.01）. ConclusionGDL can effectively improve the level of copper and lipid metabolism in patients with WD， with high clinical safety and good clinical application value. The prediction model of hepatic steatosis can effectively reflect the degree of abnormal lipid metabolism in WD.

Recommendation formation is a key component of clinical practice guidelines for Chinese patent medicine （CPM）， and should encompass the determination of the strength and direction of the recommendation， the rationale for the recommendation， and the methodology for implementing the recommendation. Recommendations can be formed through formal consensus and informal consensus. The strength and direction of recommendations for CPM guidelines should be determined by considering the quality of evidence for CPMs， the priority of the clinical questions， the pros and cons of efficacy and adverse effects， patient acceptance， the feasibility of the recommendation and the availability of resources， social fairness， economic benefits， and other influencing factors. In order to better guide guideline developers to consider these factors more rationally， this article provideed a detailed explanation of each factor in the context of the characteristics of TCM.

Objective:To translate the Cumulated Ambulation Score (CAS) into Chinese and test its reliability and validity in elderly inpatients, to provide a basis for assessing elderly inpatients′ basic mobility during hospitalization.Methods:This was a cross-sectional study. After obtaining the authorization of the original author, the Chinese version of CAS was formed by WHO′s cross-cultural translation process. A total of 414 hospitalized elderly inpatients from Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine, and Shanghai Yangpu District Kongjiang Hospital were selected between March and September 2021. Cronbach′s α coefficient was used to test internal consistency, linear weighted Kappa was employed to assess inter-rater reliability, and concurrent validity was examined using items related to mobility of Barthel Index scores as a reference standard.Results:Of the 414 patients, 221 were males and 193 were females, and the patients aged (76.67 ± 9.98) years old; 122 cases (29.5%) had a perfect score of 6 with normal basic mobility, 89 cases (21.5%) had a score of 0 with complete loss of mobility, and the remaining 203 patients had a score of 1-5 with varying degrees of reduced mobility. The Chinese version of CAS demonstrated good assessment performance for basic mobility in elderly inpatients with a Cronbach′s α coefficient of 0.952. Weighted Kappa values for individual items and total scores showed excellent agreement among raters (>0.85), while concurrent validity yielded a value of 0.935 ( P<0.01) when compared with Barthel Index scores.Total score of CAS was significantly correlated with item scores and total score of Barthel index ( r values were 0.423 to 0.944, all P<0.01). Conclusions:The Chinese version of CAS has good reliability and validity. The items are concise, clear and easy to understand. It is suitable as a preliminary screening tool for clinical departments to evaluate the basic mobility of elderly inpatients.

Objective:To explore the mechanism of Honghua Xiaoyao Tablets in the treatment of premature ovarian failure (POF) using network pharmacology and molecular docking technology; To conduct further experimental verification.Methods:The active components and related targets of Honghua Xiaoyao Tablets were obtained using TCMSP and PubChem databases, and the related targets of POF were obtained by using GeneCards database. The Venn online tool was used to screen the intersection genes, and the STRING database was used to construct the PPI network. Then, GO function enrichment analysis and KEGG pathway enrichment analysis were performed on the intersecting genes through the Metescape database, and Cytoscape 3.7.1 software was used to construct the "active component-target" network and "Chinese materia medica-active component-target-key pathway-disease" network. Finally, molecular docking verification was carried out. Mice were divided into blank group, model group, and Honghua Xiaoyao Tablets group using a random number table method, with 8 mice in each group. Except for the blank group, mice in each group were treated with zona pellucida polypeptide 3 (ZP3) and Freund's Complete Adjuvant (FCA) to establish a mouse model of immune POF. Mice in the Honghua Xiaoyao Tablets group received Honghua Xiaoyao Tablets solution 0.56 g/kg for gavage, and the blank control group and the model group received saline for gavage for consecutive 4 weeks. The histopathological changes of the mouse ovary were observed by HE staining. Immunohistochemical staining was used to observe the expression of ESR1, and Western blot was used to detect the expressions of Akt and p-Akt.Results:A total of 80 intersection targets between Honghua Xiaoyao Tablets and POF were obtained, and the PPI network contained 44 core targets. The top 5 compounds in the topological analysis were formononetin, quercetin, Betulinic acid, Hydroxysafflor Yellow A and Baicalin, and the top 5 targets were PPARG, ESR1, AR, AKT1 and IL6. The molecular function of core genes was mainly receptor ligand activity, and its biological process mainly involved the positive regulation of cell migration. The cellular components mainly included membrane rafts, which were involved in signaling pathways such as cancer signaling pathway, proteoglycans in cancer, PI3K-Akt signaling pathway, and HIF-1 signaling pathway. "Chinese materia medica-component-target-pathway-disease" network showed that 8 kinds of Chinese materia medica in the Honghua Xiaoyao Tablets had important core components, among which Glycyrrhizae Radix et Rhizoma and Carthami Flos involved the most important core components. Molecular docking results showed that the active components had a good affinity with the core target. The experimental verification confirmed that Honghua Xiaoyao Tablets promoted follicular development, increased the expression of ESR1 in ovarian tissues and up-regulated the expression level of the key factor of Akt phosphorylation in the PI3K-Akt signaling pathway.Conclusions:The various active components of Honghua Xiaoyao Tablets may act on PPARG, ESR1 and other targets through multiple signaling pathways such as PI3K-Akt and HIF-1 to treat POF. The potential active components are mainly formononetin, quercetin, etc.

Background/Aims: The shortage of donor liver hinders the development of liver transplantation. This study aimed to clarify the poor outcomes of functionally marginal liver grafts (FMLs) and provide evidence for the improvement of ischemia-free liver transplantation (IFLT) after FML transplantation. Methods: Propensity score matching was used to control for confounding factors. The outcomes of the control group and FML group were compared to demonstrate the negative impact of FMLs on liver transplantation patients. We compared the clinical improvements of the different surgical types. To elucidate the underlying mechanism, we conducted bioinformatic analysis based on transcriptome and single-cell profiles. Results: FMLs had a significantly greater hazard ratio (HR: 1.969, P=0.018) than did other marginal livers. A worse 90-day survival (Mortality: 12.3% vs. 5.0%, P=0.007) was observed in patients who underwent FML transplantation. Patients who received FMLs had a significant improvement in overall survival after IFLT (Mortality: 10.4% vs 31.3%, P=0.006). Pyroptosis and inflammation were inhibited in patients who underwent IFLT. The infiltration of natural killer cells was lower in liver grafts from these patients. Bulk transcriptome profiles revealed a positive relationship between IL-32 and Caspase 1 (R=0.73, P=0.01) and between IL-32 and Gasdermin D (R=0.84, P=0.0012). Conclusions FML is a more important negative prognostic parameter than other marginal liver parameters. IFLT might ameliorate liver injury in FMLs by inhibiting the infiltration of NK cells, consequently leading to the abortion of IL-32, which drives pyroptosis in monocytes and macrophages.

OBJECTIVE: To investigate the role of the SIRT1/NF-κB pathway in mediating the effect of puerarin against lipopolysaccharide (LPS)-induced acute kidney injury (AKI). METHODS: Fifteen BALB/C mice were randomized into control group, LPS group and puerarin treatment group, and in the latter two groups, the mice were given an intraperitoneal injection of LPS (5 mg/kg), followed by daily injection of normal saline for 3 days or injection of puerarin (25 mg/kg) given 1 h later and then on a daily basis for 3 days. On day 5 after modeling, the kidney tissues were taken for histological observation and detection of cell apoptosis. The renal function indexes including urea nitrogen (BUN), serum creatinine (Scr) and kidney injury molecule 1 (KIM-1) and the levels of tumor necrosis factor (TNF-α) and interleukin 1β (IL-1β) were measured, and the expressions of SIRT1 and NF-κB-p65(acetyl K310) in the renal tissues were detected. RESULTS: Intraperitoneal injection of LPS caused obvious glomerular capillary dilatation, hyperemia, renal interstitial edema, and renal tubular epithelial cell swelling and deformation in the mice. The mouse models of LPS-induced AKI also showed significantly increased renal tubular injury score and renal cell apoptosis (P < 0.01) with increased serum levels of BUN, Scr, KIM-1, TNF-α and IL-1β (P < 0.01), enhanced renal expressions of TNF-α, IL-1β and NF-κB p65(acetyl K310) (P < 0.01) and lowered renal expression of SIRT1 (P < 0.05). Treatment with puerarin effectively alleviated LPS-induced renal interstitial edema and renal tubular epithelial cell shedding, lowered renal tubular injury score (P < 0.01) and renal cell apoptosis rate (P < 0.01), and decreased serum levels of BUN, Scr, KIM, TNF-α and IL-1β (P < 0.01). Puerarin treatment significantly reduced TNF-α, IL-1β and NF-κB p65 (acetyl K310) expression in the renal tissue (P < 0.05) and increased SIRT1 expression by 17% (P < 0.05) in the mouse models. CONCLUSION Puerarin can effectively alleviate LPS-induced AKI in mice possibly by modulating the SIRT1/NF-κB signaling pathway.

Although primary vesical calculi is an ancient disease, the mechanism of calculi formation remains unclear. In this study, we established a novel primary vesical calculi model with d,l-choline tartrate in mice. Compared with commonly used melamine and ethylene glycol models, our model was the only approach that induced vesical calculi without causing kidney injury. Previous studies suggest that proteins in the daily diet are the main contributors to the prevention of vesical calculi, yet the effect of fat is overlooked. To assay the relationship of dietary fat with the formation of primary vesical calculi, d,l-choline tartrate-treated mice were fed a high-fat, low-fat, or normal-fat diet. Genetic changes in the mouse bladder were detected with transcriptome analysis. A high-fat diet remarkably reduced the morbidity of primary vesical calculi. Higher fatty acid levels in serum and urine were observed in the high-fat diet group, and more intact epithelia in bladder were observed in the same group compared with the normal- and low-fat diet groups, suggesting the protective effect of fatty acids on bladder epithelia to maintain its normal histological structure. Transcriptome analysis revealed that the macrophage differentiation-related gene C-X-C motif chemokine ligand 14 (Cxcl14) was upregulated in the bladders of high-fat diet-fed mice compared with those of normal- or low-fat diet-fed mice, which was consistent with histological observations. The expression of CXCL14 significantly increased in the bladder in the high-fat diet group. CXCL14 enhanced the recruitment of macrophages to the crystal nucleus and induced the transformation of M2 macrophages, which led to phagocytosis of budding crystals and prevented accumulation of calculi. In human bladder epithelia (HCV-29) cells, high fatty acid supplementation significantly increased the expression of CXCL14. Dietary fat is essential for the maintenance of physiological functions of the bladder and for the prevention of primary vesical calculi, which provides new ideas for the reduction of morbidity of primary vesical calculi.

Although several artificial nanotherapeutics have been approved for practical treatment of metastatic breast cancer, their inefficient therapeutic outcomes, serious adverse effects, and high cost of mass production remain crucial challenges. Herein, we developed an alternative strategy to specifically trigger apoptosis of breast tumors and inhibit their lung metastasis by using natural nanovehicles from tea flowers (TFENs). These nanovehicles had desirable particle sizes (131 nm), exosome-like morphology, and negative zeta potentials. Furthermore, TFENs were found to contain large amounts of polyphenols, flavonoids, functional proteins, and lipids. Cell experiments revealed that TFENs showed strong cytotoxicities against cancer cells due to the stimulation of reactive oxygen species (ROS) amplification. The increased intracellular ROS amounts could not only trigger mitochondrial damage, but also arrest cell cycle, resulting in the in vitro anti-proliferation, anti-migration, and anti-invasion activities against breast cancer cells. Further mice investigations demonstrated that TFENs after intravenous (i.v.) injection or oral administration could accumulate in breast tumors and lung metastatic sites, inhibit the growth and metastasis of breast cancer, and modulate gut microbiota. This study brings new insights to the green production of natural exosome-like nanoplatform for the inhibition of breast cancer and its lung metastasis via i.v. and oral routes.
