OBJECTIVE To investigate the improvement mechanism of hyperoside (HYP) on non-alcoholic fatty liver disease (NAFLD). METHODS Male C57BL/6 mice were randomly divided into normal (NFD) group, model (HFD) group and HYP group, with 8 mice in each group. Except for NFD group, the mice in other groups were fed with HF60 high-fat diet to establish NAFLD model; HYP group was simultaneously given HYP 100 mg/kg intragastrically every day, for 16 consecutive weeks. The body weight and liver weight of mice in each group were recorded 16 h after the last medication; the histopathological changes and lipid accumulation in the liver were observed, and the contents of triglyceride (TAG) in liver tissue and serum contents of TAG, aspartate transaminase (AST) and alanine transaminase (ALT) were measured; LC-MS/MS method was adopted to detect lipid changes in the liver tissue of mice for lipidomics analysis, and protein expressions of lipid synthesis-associated proteins peroxisome proliferator-activated receptor α (PPARα) were also tested. Human hepatocellular carcinoma cell line HepG2 was divided into normal control group, model group, HYP low-concentration group (50 μmol/L), HYP high-concentration group (100 μmol/L), HYP low-concentration+GW6471 (PPARαinhibitor) group, and HYP high-concentration+GW6471 group. Except for normal control group, the remaining cells were induced with oleic acid and palmitic acid to establish a high-fat cell model. The accumulation of lipid droplets in each group of cells was observed, and the TAG content was detected. RESULTS Compared with HFD group, HYP group exhibited significant reductions in liver fat vacuoles, lipid accumulation, liver weight, and TAG content in liver tissue, as well as serum contents of ALT, AST and TAG (P<0.05). Additionally, the expression of PPARα protein in liver tissue was significantly increased (P<0.05), and the pathological morphological changes associated with NAFLD were alleviated. Lipidomic analysis revealed that HYP significantly reduced the levels of TAG, diacylglycerol and other lipids in the liver. Compared with model group, cellular lipid droplet accumulation and TAG content decreased significantly in HYP low- and high-concentration groups (P<0.05); GW6471 could significantly reverse the improvement effect of HYP on above indicators (P<0.05). CONCLUSIONS HYP can effectively ameliorate NAFLD induced by a high-fat diet in mice, and the mechanism may be related to the activation of PPARα to regulate hepatic lipid synthesis.

Objective To investigate the role and signaling pathway mechanism of Orosomucoid-1(ORM1)in hepatocyte proliferation. Methods The expression data of ORM1 after liver resection from the GEO database were analyzed. The effects of ORM1 on hepatocyte proliferation were assessed after overexpressing ORM1 or supplementing exogenous ORM1 in liver cells. Cell proliferation was evaluated by the CCK8 assay. RNA sequencing (RNA-seq) was performed on liver tissues from ORM1 knockout mice and wildtype littermates to analyze gene expression, and KEGG enrichment analysis was employed to explore the molecular mechanisms by which ORM1 regulates hepatocyte proliferation. Results After partial liver resection in mice, ORM1 expression increased during the liver regeneration process. In vitro, ORM1 promoted the proliferation of murine Hepa1-6 hepatocytes and human HepG2 hepatocellular carcinoma cells. RNA-seq analysis of liver tissues from ORM1 knockout mice indicated that ORM1 influenced several proliferation-related pathways, including the PI3K-Akt, MAPK, Hippo, and Jak-Stat pathways. Upon ORM1 knockout, the expression of pro-proliferative genes such as Ctgf, Tcf7, Tead1, Il6ra, and Lepr decreased, while the expression of anti-proliferative genes such as Cish and Gadd45a increased. Conclusion ORM1 may promote hepatocyte proliferation by regulating key genes in cell proliferation-related pathways, including the PI3K-Akt, MAPK, Hippo and Jak-Stat pathways.

Exercise, as a non-pharmacological intervention, holds a pivotal role in metabolic regulation, neuroplasticity, and immune homeostasis maintenance. However, human exercise studies are constrained by ethical limitations in tissue sampling, especially for key organs such as muscles and the brain. Meanwhile, rodent models like mice exhibit physiological differences in exercise patterns and metabolic rates from human. Despite these challenges, approximately 70% of human and mouse genes are conserved, providing a molecular basis for cross-species comparisons. This paper leverages the GEPREP database, which integrates human and mouse exercise transcriptomic data from multiple platforms, to conduct a comprehensive cross-species analysis of exercise-induced gene expression patterns. We employ a stringent data standardization process, including the conversion of orthologous genes and the filtering of low-expressing genes, to ensure the accuracy and reliability of the analysis. A mixed-effects model is utilized to assess differential gene expression across multiple cohorts, identifying genes that are significantly upregulated or downregulated in response to exercise. The analysis reveals a complex pattern of gene expression, with a significant number of genes showing conserved responses between humans and mice, particularly in acute aerobic exercise, where genes such as ATF3, PPARGC1A, and ANKRD1 are commonly upregulated. These genes are implicated in muscle stress response, metabolic regulation, and muscle adaptation, highlighting the shared molecular pathways activated by exercise across species. However, the study also uncovers substantial species-specific differences in gene expression, especially in chronic aerobic exercise, where the number of divergently regulated genes increases. These differences suggest that while some fundamental biological processes are conserved, the specific regulatory mechanisms and gene expression patterns can vary significantly between humans and mice. Functional enrichment analysis further reveals that conserved genes are involved in muscle development, inflammation regulation, and energy metabolism, while species-specific genes are associated with ion transport, extracellular matrix (ECM) organization, and muscle contraction, indicating the multifaceted impact of exercise on skeletal muscle function. The findings emphasize the importance of considering species-specific differences when interpreting results from animal models and translating them to human health applications. The study highlights the need for a more nuanced understanding of the molecular underpinnings of exercise-induced adaptations and underscores the value of cross-species comparative analyses in uncovering the evolutionary and functional basis of these responses. Future research should focus on integrating multi-omics data and expanding the analysis to include other tissues to provide a more comprehensive view of the systemic effects of exercise. Additionally, the development of species-specific gene editing models and the validation of key genes in exercise physiology will further enhance our understanding of the evolutionary logic behind exercise interventions. This study not only provides valuable insights into the molecular mechanisms of exercise-induced adaptations but also underscores the necessity of validating findings from animal models in human cohorts to ensure the reliability and applicability of translational research in exercise science. By addressing these aspects, the study aims to bridge the gap between basic research and clinical applications, ultimately contributing to the development of personalized exercise prescriptions and interventions that can effectively promote health and prevent diseases.

OBJECTIVE To evaluate the contents of characteristic components in Hugan qingzhi formula (HGQZ) decoction and formulated granules and the pharmacodynamic consistency of them on high-fat diet-induced non-alcoholic fatty liver disease (NAFLD) model mice, and explore their potential underlying mechanisms of action. METHODS Liquid chromatography-tandem mass spectrometry was used to analyze and compare the contents of six characteristic components in HGQZ decoction and formulated granules. Male C57BL/6 mice were randomly divided into normal control group, model group, HGQZ decoction low- dose and high-dose groups (13, 26 g/kg, calculated by crude drugs), and HGQZ formulated granules low-dose and high-dose groups (13, 26 g/kg, calculated by crude drugs), with 6 mice in each group. Except for the normal control group, which was fed a regular diet, the mice in the other groups were fed a high-fat diet for 20 weeks to establish the NAFLD model; at the same time, the mice in each group were gavaged with the corresponding drugs/water once. The fasting blood glucose (FBG) levels, glucose and insulin tolerance, body weight, liver index, white adipose Δ 基金项目 国家自然科学基金项目(No.82074078);广东省基础 tissue index, brown adipose tissue index, as well as lipid levels (total cholesterol, triglycerides) and liver function indicators (aspartate transaminase, alanine transaminase) were measured. Additionally, histopathological changes and lipid accumulation in liver tissues were observed. The serum samples of mice in the model group, HGQZ decoction high-dose group and HGQZ formulated granules high-dose group were taken for metabolomics analysis, and validation of the underlying mechanisms was conducted. RESULTS There were no statistically significant differences in the contents of ginsenoside Rb1, typhaneoside, isorhamnetin-3-O-neohesperidoside, hyperoside, nuciferine, and 23-acetylalismol B between HGQZ decoction and HGQZ formulated granules (P>0.05). Compared with the model group, the hepatic histopathological changes in mice were alleviated in both the HGQZ decoction group and all dose groups of HGQZ formulated granules. Inflammatory cell infiltration and lipid vacuoles were reduced. Additionally, there was a general improvement in FBG levels, glucose tolerance, insulin tolerance, body weight, liver index, white/brown adipose tissue index, lipid levels, and liver function indicators (P<0.05). However, no statistically significant differences were observed between these treatment groups (P>0.05). There were 234 and 136 differentially expressed serum metabolites identified in the model group versus HGQZ decoction high-dose group, and model group versus HGQZ formulated granules high-dose group, respectively. After taking the intersection, 65 common differentially expressed metabolites were obtained, which were enriched in metabolic pathways such as purine metabolism and tricarboxylic acid cycle metabolism. Among these, the content of citrate in the model group was significantly lower than that in both the HGQZ decoction group and HGQZ formulated granules high-dose group (P<0.05). Both high-dose HGQZ decoction and formulated granules could significantly elevate the phosphorylation levels of AMP-activated protein kinase (AMPK) (P<0.05). CONCLUSIONS HGQZ decoction and formulated granules contain comparable amounts of characteristic components, and both exhibit equivalent efficacy on NAFLD model mice. The anti-NAFLD effects of HGQZ are associated with the activation of the AMPK energy metabolism pathway.

ObjectiveTo evaluate a third-generation applicator template for intracavitary combined with interstitial brachytherapy (IC-ISBT) suitable for locally advanced cervical cancer, aiming to improve therapeutic outcomes. MethodsA retrospective study was conducted on patients with stage IB3-ⅣB cervical cancer treated at Sun Yat-sen University Cancer Center from January 2023 to October 2023. Magnetic resonance imaging data before and after external beam radiation therapy were collected and analyzed. According to the residual tumor after external beam radiation, high-risk clinical target volumes (HR-CTV) were delineated, based on which a third-generation IC-ISBT applicator template was designed. The dosimetric and therapeutic differences between using this applicator template (template implantation group) and traditional freehand interstitial implantation (freehand implantation group) were further compared. Statistical methods were used to analyze the data from both groups to test the efficacy and safety of the two approaches. ResultsThe third-generation applicator template could accommodate different cervical structures and optimize needle path layout. The tumor volume in the template implantation group was significantly larger than in the freehand implantation group, showing statistical differences. In terms of dosimetric coverage (V100%), the template implantation group exhibited significant statistical differences compared with the freehand implantation group, demonstrating superior dose coverage. Additionally, the third-generation template showed advantages in protecting the rectum and sigmoid colon by potentially reducing high-dose points, while there were no significant differences in bladder dosimetry between the two methods. The primary cervical lesion remission rates were similar between the two groups. ConclusionThe third-generation IC-ISBT applicator template is scientifically and rationally designed, especially for patients with larger tumor volumes and later stages. It is easy to operate, highly reproducible, and shows significant advantages in dose distribution and protection of surrounding critical organs. The template has the potential to be widely applied as a routine treatment option.

ObjectiveTo explore the effect of Yishen Tongluo prescription on sperm DNA fragmentation index (DFI) and sperm mitochondrial membrane potential (MMP) in patients with asymptomatic idiopathic asthenospermia infertility. MethodsA total of 128 patients with asymptomatic idiopathic asthenospermia were randomly assigned to an experimental group (64 cases) and a control group (64 cases). The experimental group received Yishen Tongluo prescription, while the control group was treated with Wuzi Yanzongwan combined with L-carnitine oral solution. One treatment course lasted 12 weeks. Spouse pregnancy rate, sperm progressive motility (PR), total sperm motility (PR+NP), sperm function (sperm tail hypotonic swelling rate, sperm acrosin activity), sperm DFI, and sperm MMP were compared between the two groups before and after treatment. Adverse reactions were observed and recorded during the study, and clinical efficacy and safety were systematically evaluated. ResultsA total of 121 patients completed the study, including 61 in the experimental group and 60 in the control group. The spouse pregnancy rate in the experimental group was 14.75% (9/61), higher than that in the control group at 6.67% (4/60), though the difference was not statistically significant. Clinical efficacy in the experimental group was superior to that in the control group (P<0.05). Compared with the results before treatment, sperm PR, PR + NP, sperm tail hypotonic swelling rate, sperm acrosin activity, sperm DFI, and sperm MMP were significantly improved in both groups after treatment (P<0.05), with greater improvements in the experimental group (P<0.05). However, there was no significant change in sperm concentration in either group after treatment. During the study, no abnormal safety indicators or significant adverse reactions occurred in either group. ConclusionThe kidney-tonifying and collateral-dredging method shows good clinical efficacy in the treatment of asymptomatic idiopathic asthenospermia infertility. Yishen Tongluo prescription can improve sperm motility, increase spouse pregnancy rate, enhance sperm function, and demonstrates good safety. Its mechanism may be related to reducing sperm DFI and increasing sperm MMP.

Objective:
To understand the dynamic temporal evolution pathways of Internet addiction among university students and to identify the core driving nodes, so as to provide theoretical evidences for the precise implementation of targeted interventions.
Methods:
Using a convenient cluster sampling method, a total of 1 066 full time freshmen and sophomores were recruited from three universities in Guizhou, Jiangxi, and Guangdong Provinces for a follow up survey (T1:January-March 2024; T2:January-March 2025). The Revised Chen Internet Addiction Scale (CIAS-R) was employed to assess the status of Internet addiction among university students, and cross sectional as well as cross lagged panel network models were constructed to analyze Internet addiction and its multidimensional influencing factors.
Results:
The T1 network comprised 19 nodes and 114 non zero edges, while the T2 network comprised 19 nodes and 126 non zero edges. Cross sectional network analysis revealed the strongest association between "insufficient sleep" and "daytime fatigue"; the core nodes were "first thought upon waking for going online" and "feeling low after disconnection" (characteristics of psychological dependence) at T1, while the core nodes shifted to "impaired health" and "excitement when online" (characteristics of functional impairment and addictive psychodynamic features) at T2. Cross lagged network analysis further indicated that "reduced leisure" directly predicted "sleep compression", and a bidirectional relationship was observed between "needing more time to achieve satisfaction" and "academic decline".
Conclusions
Internet addiction among university students exhibits dynamic evolutionary characteristics. Stage specific targeted interventions focusing on core driving nodes are needed, integrating behavioral regulation and academic support to break the vicious cycle and enhancing the ability to cope with real life demands.

Immune evasion has made ovarian cancer notorious for its refractory features, making the development of immunotherapy highly appealing to ovarian cancer treatment. The immune-stimulating cytokine IL-12 exhibits excellent antitumor activities. However, IL-12 can induce IFN-γ release and subsequently upregulate PDL-1 expression on tumor cells. Therefore, the tumor-targeting folate-modified delivery system F-DPC is constructed for concurrent delivery of IL-12 encoding gene and small molecular PDL-1 inhibitor (iPDL-1) to reduce immune escape and boost anti-tumor immunity. The physicochemical characteristics, gene transfection efficiency of the F-DPC nanoparticles in ovarian cancer cells are analyzed. The immune-modulation effects of combination therapy on different immune cells are also studied. Results show that compared with non-folate-modified vector, folate-modified F-DPC can improve the targeting of ovarian cancer and enhance the transfection efficiency of pIL-12. The underlying anti-tumor mechanisms include the regulation of T cells proliferation and activation, NK activation, macrophage polarization and DC maturation. The F-DPC/pIL-12/iPDL-1 complexes have shown outstanding antitumor effects and low toxicity in peritoneal model of ovarian cancer in mice. Taken together, our work provides new insights into ovarian cancer immunotherapy. Novel F-DPC/pIL-12/iPDL-1 complexes are revealed to exert prominent anti-tumor effect by modulating tumor immune microenvironment and preventing immune escape and might be a promising treatment option for ovarian cancer treatment.

ObjectiveTo investigate the effect of galvanic vestibular stimulation on stroke patients with lateropulsion. MethodsFrom February to October, 2023, 30 stroke patients with lateropulsion in the First Affiliated Hospital of Nanjing Medical University were divided into control group (n = 15) and experimental group (n = 15) randomly. The control group received routine rehabilitation and sham galvanic vestibular stimulation, and the experimental group received routine rehabilitation and true galvanic vestibular stimulation, for two weeks. They were assessed with Scale for Contraversive Pushing (SCP), subjective visual vertical (SVV), Line Cancellation Test (LCT), Star Cancellation Test (SCT), Berg Balance Scale (BBS), Holden Functional Ambulation Category (FAC) and Barthel Index (BI) before and after treatment. ResultsAll the indexes improved in both groups after intervention (|t| > 2.461, Z > 3.000, P < 0.05), except the SVV orientation, SVV certainty and SCT in the control group; while the SCP, SVV certainty, LCT and FAC were better in the experimental group than in the control group (|t| > 2.189, Z = -2.862, P < 0.05), and the differences before and after intervention were better in the experimental group than in the control group (|t| > 2.382, P < 0.05), except LCT. SCP was correlated with SVV orientation, SVV certainty, SCT, BBS, BI and FAC (|r| > 0.381, P < 0.05). ConclusionGalvanic vestibular stimulation can improve the lateropulsion, balance, walking function and activities of daily living in stroke patients, which may be related to improvement for spatial cognitive function, especially vertical perception.
