Objective: To explore effects of cumulative family risk in university students on individuals internalizing problems, to elucidate the mediating roles of perceived social support and self esteem in the relationship, so as to provide a basis for promoting university student s mental health. Methods: Using longitudinal design, 1 207 freshmen from a university in Tianjin were randomly selected and surveyed in November 2023 (T1) and November 2024 (T2). The instruments included the Cumulative Family Risk Scale, the Perceived Social Support Scale, the Self esteem Scale, and the College Student Mental Health Screening Scale. Structural equation modeling (SEM) was constructed, with Bootstrap method used to test mediating effects and to examine gender differences. Results: The results showed that cumulative family risk at T1 with internalizing problems at T1( r =0.30) and internalizing problems at T2 ( r =0.32) were significantly positively correlated (both P <0.01). Mediation analysis indicated that the independent mediating effect of perceived social support at T1，cumulative family risk at T1 and internalizing problems at T2 was 0.03 (95% CI =0.02-0.05), and the independent mediating effect of self esteem at T1 was 0.08 (95% CI = 0.06 -0.10) (both P <0.05). The chain mediating effect of perceived social support and self esteem at T1 was 0.02 (95% CI =0.02-0.03) ( P <0.05). Significant gender differences were observed in the path from cumulative family risk to self esteem ( β male =-0.24, β female =-0.35) and in the path from perceived social support to self esteem ( β male =0.41, β female =0.25) (all P <0.05). Conclusion Cumulative family risk reduces internalizing behaviors in university students via internal and external development resources, with gender specific mechanisms.

Objective: To investigate the trend in disease burden of injuries among children and adolescents in China from 1990 to 2021, so as to provide a basis for formulating prevention and control strategies and reducing this disease burden. Methods: Data on mortality, disability-adjusted life years (DALY) rate, incidence, and prevalence of injuries among children and adolescents aged <20 years in China from 1990 to 2021 were collected from the Global Burden of Disease (GBD) 2021 database. All rates were standardized using the GBD 2021 world standard population. The trend in incidence of disease burden of injuries among children and adolescents across differents genders and ages from 1990 to 2021 was evaluated using average annual percent change (AAPC). Results: From 1990 to 2021, the standardized mortality (AAPC=-5.435%), standardized DALY rate (AAPC=-5.311%), standardized incidence (AAPC=-0.466%), and standardized prevalence (AAPC=-0.810%) of injuries among children and adolescents in China showed downward trends (all P<0.05). Among these, the standardized mortality of animal contact (AAPC=-9.138%) and the standardized DALY rate of medical side effects (AAPC=-8.389%) decreased at a relatively fast pace, while the standardized incidence of falls (AAPC=0.083%) and the standardized prevalence of exposure to natural forces (AAPC=2.656%) showed upward trends (all P<0.05). The standardized mortality, standardized DALY rate, standardized incidence and standardized prevalence of injuries were higher in males than in females. The trend in males showed a downward trend (all P<0.05), consistent with the total population. The crude incidence of injuries in the group aged 15-<20 years showed an upward trend (AAPC=0.391%, P<0.05), while the trend in the group aged 10-<15 years was not statistically significant (P>0.05). The crude incidence of injuries in the groups aged 5-<10 years and <5 years showed downward trends (AAPC=-0.488% and -2.275%, both P<0.05). In 2021, the <5 years age group had the highest crude mortality and crude DALY rate of injuries, at 13.94/100 000 and 1 257.26/100 000, respectively. The 15-<20 years age group exhibited the highest crude incidence and crude prevalence, at 4 874.05/100 000and 4 050.35/100 000, respectively. Drowning and falls were major components of the disease burden across all age groups. Conclusions From 1990 to 2021, the disease burden of injuries among children and adolescents in China showed an overall downward trend. The disease burden was consistently higher in males than in females. Children aged <5 years face a high risk of fatality and disability, while adolescents aged 15-<20 years experience a high incidence and frequency of injuries. Drowning and falls were key priorities for prevention and control.

OBJECTIVES: To analyze MYO1B expression in gastric cancer, its association with long-term prognosis and its role in regulating biological behaviors of gastric cancer cells. METHODS: We analyzed MYO1B expression in gastric cancer and its correlation with tumor grade, tumor stage, and patient survival using the Cancer Public Database. We also examined MYO1B expression with immunohistochemistry in gastric cancer and paired adjacent tissues from 105 patients receiving radical surgery and analyzed its correlation with cancer progression and postoperative 5-year survival of the patients. GO and KEGG enrichment analyses were used to explore the biological functions of MYO1B and the key pathways. In cultured gastric cancer cells, we examined the changes in cell proliferation, migration and invasion following MYO1B overexpression and knockdown. RESULTS: Data from the Cancer Public Database showed that MYO1B expression was significantly higher in gastric cancer tissues than in normal tissues with strong correlations with tumor grade, stage and patient prognosis (P<0.05). In the clinical tissue samples, MYO1B was significantly overexpressed in gastric cancer tissues in positive correlation with Ki67 expression (r=0.689, P<0.05) and the parameters indicative of gastric cancer progression (CEA ≥5 μg/L, CA19-9 ≥37 kU/L, G3-4, T3-4, and N2-3) (P<0.05). Kaplan-Meier analysis and multivariate Cox regression analysis suggested that high MYO1B expression was associated with decreased postoperative 5-year survival and was an independent risk factor (HR: 3.522, 95%CI: 1.783-6.985, P<0.05). MYO1B expression level was a strong predictor of postoperative survival (cut-off value: 3.11, AUC: 0.753, P<0.05). GO and KEGG analyses suggested that MYO1B may regulate cell migration and the mTOR signaling pathway. In cultured gastric cancer cells, MYO1B overexpression significantly enhanced cell proliferation, migration, and invasion and promoted the phosphorylation of Akt and mTOR. CONCLUSIONS High MYO1B expression promotes proliferation, migration and invasion of gastric cancer cells and is correlated with poor patient prognosis.

OBJECTIVES: To investigate YEATS2 expression in gastric cancer (GC), its prognostic value, and its regulatory role in epithelial-mesenchymal transition (EMT) of GC cells. METHODS: YEATS2 expression in GC was analyzed using publicly available databases. Paired GC and adjacent tissues were collected from 100 patients undergoing radical surgery for immunohistochemical detection of YEATS2 expression, and its correlations with the patients' clinicopathological parameters and Ki67 expression were analyzed. The prognostic value of YEATS2 was assessed using Kaplan-Meier analysis, Cox regression and ROC curves, and its regulatory mechanisms were analyzed using KEGG enrichment analysis. In cultured GC cell lines (HGC-27 and AGS), the effect of YEATS2 knockdown and overexpression on migration, invasion and EMT of the cells were examined with scratching assay, Transwell assay and Western blotting. RESULTS: YEATS2 was significantly overexpressed in GC tissues with a positive correlation with Ki67 (P<0.05). High YEATS2 expression was associated with elevated CEA (≥5 μg/L), CA19-9 (≥37 kU/L), T3-4 stage, and N2-3 stage (all P<0.05). Patients with high YEATS2 expression had significantly reduced 5-year survival (P<0.001); ROC analysis showed that YEATS2 expression levels had a sensitivity of 80.00% and a specificity of 66.67% for predicting patient survival (P<0.05). Cox regression identified high YEATS2 as an independent risk factor for poor postoperative 5-year survival outcome of GC patients (HR: 1.675, 95%CI: 1.013-2.771; P=0.045). KEGG enrichment analysis suggested involvement of YEATS2 in EMT in GC and Wnt/β-catenin signaling. In cultured GC cells, YEATS2 overexpression significantly promoted cell migration and invasion, upregulated the expressions of vimentin, N-cadherin, Wnt and active β-catenin, and downregulated E-cadherin expression, and these changes were obviously suppressed by treatment with XAV-939 (a Wnt/β-catenin inhibitor). CONCLUSIONS High YEATS2 expression activates Wnt/β-catenin signaling to promote EMT in GC and is correlated with poor prognosis of GC patients.

OBJECTIVES: To investigate the effect of hypaphorine (HYP) on Crohn's disease (CD)‑like colitis in mice and its molecular mechanism. METHODS: Thirty male C57BL/6J mice were equally randomized into WT, TNBS, and HYP groups, and in the latter two groups, mouse models of CD-like colitis were established using TNBS with daily gavage of 15 mg/kg HYP or an equivalent volume of saline. The treatment efficacy was evaluated by assessing the disease activity index (DAI), body weight changes, colon length and histopathology. The effect of HYP was also tested in a LPS-stimulated Caco-2 cell model mimicking intestinal inflammation by evaluating inflammatory responses and barrier function of the cells using qRT-PCR and immunofluorescence staining. GO and KEGG analyses were conducted to explore the therapeutic mechanism of HYP, which was validated in both the cell and mouse models using Western blotting. RESULTS: In the mouse models of CD-like colitis, HYP intervention obviously alleviated colitis as shown by significantly reduced body weight loss, colon shortening, DAI and inflammation scores, and expressions of pro-inflammatory factors in the colon tissues. HYP treatment also significantly increased the TEER values, reduced bacterial translocation to the mesenteric lymph nodes, liver, and spleen, lowered serum levels of I-FABP and FITC-dextran, increased the number of colonic tissue cup cells, and upregulated colonic expressions of MUC2 and tight junction proteins (claudin-1 and ZO-1) in the mouse models. In LPS-stimulated Caco-2 cells, HYP treatment significantly inhibited the expressions of pro-inflammatory factors and increased the expressions of tight junction proteins. Western blotting showed that HYP downregulated the expressions of the key proteins in the TLR4/MyD88 signaling pathway in both the in vitro and in vivo models. CONCLUSIONS HYP alleviates CD-like colitis in mice possibly by suppressing intestinal epithelial inflammation and improving gut barrier function.

Astragali Radix (AR), a traditional Chinese medicine (TCM), has demonstrated therapeutic efficacy against various diseases, including cardiovascular conditions, over centuries of use. While doxorubicin serves as an effective chemotherapeutic agent against multiple cancers, its clinical application remains constrained by significant cardiotoxicity. Research has indicated that AR exhibits protective properties against doxorubicin-induced cardiomyopathy (DIC); however, the specific bioactive components and underlying mechanisms responsible for this therapeutic effect remain incompletely understood. This investigation seeks to identify the protective bioactive components in AR against DIC and elucidate their mechanisms of action. Through network medicine analysis, astragaloside IV (AsIV) and formononetin (FMT) were identified as potential cardioprotective agents from 129 AR components. In vitro experiments using H9c2 rat cardiomyocytes revealed that the AsIV-FMT combination (AFC) effectively reduced doxorubicin-induced cell death in a dose-dependent manner, with optimal efficacy at a 1∶2 ratio. In vivo, AFC enhanced survival rates and improved cardiac function in both acute and chronic DIC mouse models. Additionally, AFC demonstrated cardiac protection while maintaining doxorubicin's anti-cancer efficacy in a breast cancer mouse model. Lipidomic and metabolomics analyses revealed that AFC normalized doxorubicin-induced lipid profile alterations, particularly by reducing fatty acid accumulation. Gene knockdown studies and inhibitor experiments in H9c2 cells demonstrated that AsIV and FMT upregulated peroxisome proliferator activated receptor γ coactivator 1α (PGC-1α) and PPARα, respectively, two key proteins involved in fatty acid metabolism. This research establishes AFC as a promising therapeutic approach for DIC, highlighting the significance of multi-target therapies derived from natural herbals in contemporary medicine.

Short-chain fatty acids are metabolites produced by anaerobic bacteria fermenting undigested carbohydrates in the cecum and colon.After being absorbed in the colon，they can regulate intestinal energy metabolism，maintain intestinal mucosal barrier function，regulate intestinal immune function，affect intestinal secretion and absorption，and regulate intestinal microecology through the above functions，thereby changing the frequency of defecation in children.With the in-depth understanding of intestinal microecology，it has been found that the metabolites of intestinal flora also play an important role in the human body.When the frequency of defecation in children changes，the composition of intestinal flora changes，and the content of short-chain fatty acids produced by intestinal flora metabolism also changes.This article reviews the role and mechanism of short-chain fatty acids in children's different defecation frequencies，and provides treatment ideas for children's different defecation frequencies.

Objective:To perform two-step clustering analysis based on urodynamics in patients with neurogenic bladder (NB) and exploring characteristics affecting success rate of sacral neuromodulation (SNM).Methods:The data of 174 NB patients who received SNM therapy in our hospital from September 2018 to August 2023, were retrospectively analysed. There were 94 males and 80 females, with average age of (50.4±17.9)years, median duration of 2 (1, 3)years, and body mass index of 21.5 (20, 25) kg/m 2. Among them, 50 patients had chronic diseases (hypertension or diabetes). Additionally, 77 patients (44.3%) presented with voiding symptoms, 47 patients (27.0%) with storage symptoms, and 50 patients (28.7%) with mixed symptoms. The etiologies included spinal cord lesions in 110 patients (63.2%), brain lesions in 21 patients (12.1%), peripheral nerve lesions in 36 patients (20.7%), and other causes in 7 patients (4.0%). All patients underwent urodynamics and SNM phase 1 test. If patient's subjective symptoms or objective indicators improved > 50%, it is defined as treatment success and feasible to received second stage of SNM. The success rate was analyzed. Clinical indicators and urodynamic parameter were collected for exploring the difference of the above indicators between two groups (with or without conversion). The 174 patients were grouped using two-step clustering analysis, dividing them into two groups. The differences in clinical data, urodynamic parameters, and the conversion rate of SNM phase II between the two groups were compared. Results:Among these patients, 126 (72%) underwent the second stage of SNM. Compared with the non-conversion group, patients in the conversion group exhibited the following characteristics: high proportion of female[51.6% (65/126) vs. 31.2% (15/48)], younger[(48.1± 18.3)year vs. (56.4±15.4) year], lower proportion of history of chronic disease[23.9% (30/126) vs. 41.7% (20/48)], storage predominant symptoms predominant[33.3% (42/126) vs. 10.4% (5/48)], sensitive bladder sensation[50.0% (63/126) vs. 11.1% (14/48)], normal detrusor contractility [26.2% (33/126) vs. 10.4% (5/48)] and detrusor-sphincter dyssynergia [21.4% (27/126) vs. 4.2% (2/48)]and lower post-void residual [105.5(49.3, 231.3) ml vs. 197.9(114.8, 284.8) ml], ( P<0.05). After excluding multicollinearity, patients were divided into two group mainly based on coordination, detrusor stability, and detrusor contractility through two-step clustering analysis: 98 patients in Group 1 and 76 patients in Group 2. The success rate was higher in Group 2 [82.9% (63/76) vs. 64.3% (63/98), P=0.006]. Compared with Group 1, Group 2 exhibited the following characteristics: higher proportion of storage symptoms [43.4% (33/76) vs. 14.3% (14/98)], sensitive bladder sensation [67.1% (51/76) vs. 26.5% (26/98)], detrusor overactivity [46.1% (35/76) vs. 3.1% (3/98)], normal detrusor contractility [43.4% (33/76) vs. 5.1% (5/98)], and detrusor-sphincter dyssynergia [38.2% (29/76) vs. 0] ( P all<0.05). Additionally, group 2 had lower post-void residual [69.0 (23.8, 136.6) ml and 197.9 (123.2, 287.4) ml] and smaller bladder capacity [(281.9±144.9) ml vs. (430.4±176.7) ml] ( P all<0.01). Conclusions:Patients with storage symptoms, low post-void residual, sensitive bladder sensation, detrusor overactivity, normal contractility, or detrusor-sphincter dyssynergia indicate a higher conversion rate to second stage, making them more suitable for SNM testing.
