Gegen Qinlian Decoction(GQD) is a classic prescription for the clinical treatment of ulcerative colitis(UC). This study, based on the differences in efficacy observed in UC mice under different level of bile acids treated with GQD, aims to clarify the impact of bile acids on UC and its therapeutic effects. It further investigates the expression of bile acid receptors in the liver of UC mice, and preliminarily reveals the mechanism through which GQD affects bile acid synthesis in the treatment of UC. A UC mouse model was established using dextran sulfate sodium(DSS) induction. The efficacy of GQD was evaluated by assessing the general condition, disease activity index(DAI) score, colon length, and histopathological changes in colon tissue via hematoxylin and eosin(HE) staining. ELISA and Western blot were used to evaluate the inflammatory response in colon tissue. The total bile acid(TBA) level and liver damage were quantified using an automatic biochemistry analyzer. The expression levels of bile acid receptors and bile acid synthetases in liver tissue were detected by Western blot and RT-qPCR. The results showed that compared with the model group, GQD treatment significantly improved the DAI score, colon shortening, and histopathological damage in UC mice. The levels of pro-inflammatory factors TNF-α and IL-6 in the colon were significantly reduced. Serum TBA levels were significantly decreased, while alkaline phosphatase(ALP) levels significantly increased. After administration of cholic acid(CA), UC symptoms in the CA + GQD group were significantly aggravated compared with the GQD group. The DAI score, degree of weight loss, colon injury, serum TBA, and liver injury markers all increased significantly. However, compared with the CA group, the CA + GQD group showed a marked reduction in TBA levels and a significant improvement in UC-related symptoms, indicating that GQD can alleviate UC damage exacerbated by CA. Further investigation into the expression of bile acid receptors and synthetases in the liver showed that under GQD treatment, the expression of farnesoid X receptor(FXR) and small heterodimer partner(SHP) significantly increased, while the expression of G protein-coupled receptor 5(TGR5) and cholesterol 7α-hydroxylase(Cyp7A1) significantly decreased. These findings suggest that GQD may affect bile acid receptors and synthetases, inhibiting bile acid synthesis through the FXR/SHP pathway to treat UC.

OBJECTIVE:
To explore the improvement effect of rehabilitation nursing based on information-knowledge-belief-behavior (IKAP) theory on urinary incontinence patients after radical prostatectomy.
METHODS
Sixty-six patients with urinary incontinence who received robot-assisted laparoscopic radical prostatectomy in General Hospital of Eastern Theater Command from January 2021 to January 2023 were selected and divided into control group (n=33) and observation group (n=33) according to random number table method. The patients in the control group were treated with rehabilitation nursing. The patients in the observation group were treated with rehabilitation nursing guided by IKAP theory. The recovery of urinary incontinence, duration of urinary incontinence, subjective well-being, quality of life, psychological and emotional indexes of patients in the two groups were compared. Results: The total effective rate of urinary incontinence recovery in the observation group was significantly higher than that in the control group (90.91% vs 60.61%,P<0.05). The duration of urinary incontinence in the observation group was significantly shorter than that in the control group ([3.36±1.54]d vs [4.15±1.36]d,P<0.05). And the subjective well-being score in observation group was significantly higher than that in the control group ([19.36±2.69]points vs [11.65±2.65]points, P<0.05). There was no significant difference in preoperative physical function, social function,and mental health scores between the two groups (P>0.05). And all scores in the observation group were significantly higher than those in the control group after surgery (P<0.05). There was no significant difference in the preoperative SAS and SDS scores between the two groups of patients (P>0.05). And the scores of SAS and SDS in observation group were lower than those of the control group after the operation (P<0.05). Conclusion: Rehabilitation nursing based on IKAP theory can significantly improve urinary incontinence in patients with prostate cancer after surgery, which promotes the recovery of urinary incontinence, shortens the time of urinary incontinence, and improves the subjective well-being and quality of life, as well as reduces the negative impact of negative emotions. Therefore, it can be widely promoted and implemented in clinical practice.

Hearing loss is the most prevalent disabling disease. Cochlear implantation(CI) serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system(Favorable, Marginal, Poor). The consensus focuses on common hereditary non-syndromic hearing loss(such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1) and syndromic hereditary hearing loss(such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome), which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

OBJECTIVE:
This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study.
METHODS:
A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants.
RESULTS:
Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m 2) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m 2) and obesity (≥ 28.0 kg/m 2) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m 2 ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses.
CONCLUSION
This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Background:
Diabetes-induced cardiac fibrosis is one of the main mechanisms of diabetic cardiomyopathy. As a common histone methyltransferase, enhancer of zeste homolog 2 (EZH2) has been implicated in fibrosis progression in multiple organs. However, the mechanism of EZH2 in diabetic myocardial fibrosis has not been clarified.
Methods:
In the current study, rat and mouse diabetic model were established, the left ventricular function of rat and mouse were evaluated by echocardiography and the fibrosis of rat ventricle was evaluated by Masson staining. Primary rat ventricular fibroblasts were cultured and stimulated with high glucose (HG) in vitro. The expression of histone H3 lysine 27 (H3K27) trimethylation, EZH2, and myocardial fibrosis proteins were assayed.
Results:
In STZ-induced diabetic ventricular tissues and HG-induced primary ventricular fibroblasts in vitro, H3K27 trimethylation was increased and the phosphorylation of EZH2 was reduced. Inhibition of EZH2 with GSK126 suppressed the activation, differentiation, and migration of cardiac fibroblasts as well as the overexpression of the fibrotic proteins induced by HG. Mechanical study demonstrated that HG reduced phosphorylation of EZH2 on Thr311 by inactivating AMP-activated protein kinase (AMPK), which transcriptionally inhibited peroxisome proliferator-activated receptor γ (PPAR-γ) expression to promote the fibroblasts activation and differentiation.
Conclusion
Our data revealed an AMPK/EZH2/PPAR-γ signal pathway is involved in HG-induced cardiac fibrosis.

This study investigated the effects of Agrimoniae Herba-Coptidis Rhizoma(XHC-HL)-medicated serum on the proliferation, migration, invasion, and apoptosis of human colorectal cancer HT29 and HCT116 cells via the autophagy mediated by lysosome-associated membrane protein type 2A(LAMP2A). Bioinformatics analysis was conducted to explore the role of LAMP2A in the development and progression of colorectal cancer. Western blot(WB) was used to detect the expression of LAMP2A protein in colorectal cancer cell lines. Lentiviral transfection was utilized to construct LAMP2A knockdown in HT29 and overexpression in HCT116 colorectal cancer cell models. Real-time fluorescence quantitative polymerase chain reaction(real-time qPCR) was performed to assess transfection efficiency. HT29 and HCT116 cells were treated with different concentrations of XHC-HL-medicated serum. The cell counting kit-8(CCK-8) assay was used to detect cell proliferation and determine the optimal concentration and duration of medicated serum intervention. HT29 cells were divided into a normal control(NC) group, an XHC-HL(medicated serum treatment) group, and an XHC-HL+shLAMP2A(medicated serum treatment+LAMP2A knockdown) group. HCT116 cells were divided into a NC group, an XHC-HL group, and an XHC-HL+LAMP2A(medicated serum treatment+LAMP2A overexpression) group. CCK-8 was used to measure cell viability. Colony formation assay was employed to assess cell proliferation ability. Scratch and Transwell migration assays were conducted to evaluate cell migration ability, and Transwell invasion assay was used to detect cell invasion ability. Flow cytometry was adopted to determine apoptosis rates. WB and real-time qPCR were employed to detect the effect of XHC-HL on the protein and mRNA expression of LAMP2A, heat shock cognate protein 70(HSC70), heat shock protein 90(HSP90), and glyceraldehyde-3-phosphate dehydrogenase(GAPDH) in colorectal cancer cells. Differential expression analysis revealed that LAMP2A expression was significantly higher in colorectal cancer patients compared to that in normal controls. Survival analysis indicated that the key molecule of chaperone-mediated autophagy(CMA), LAMP2A, was closely associated with colorectal cancer progression. Gene set enrichment analysis showed that patients with high LAMP2A expression significantly upregulated tumor progression-related signaling pathways such as angiogenesis and immune suppression. Immune infiltration analysis found that patients with high LAMP2A expression had fewer CD8 T cell infiltrations in their tumor microenvironment. XHC-HL-medicated serum inhibited the viability of HT29 and HCT116 cells, with the optimal intervention concentration and duration being 20% and 48 hours, respectively. Compared to the NC group, XHC-HL inhibited the proliferation, migration, and invasion of HT29 and HCT116 cells, and induced apoptosis. The medicated serum treatment with LAMP2A knockdown further inhibited colorectal cancer cell proliferation, invasion, and migration, and promoted apoptosis, whereas overexpression of LAMP2A reversed the inhibitory effects of the medicated serum on proliferation, migration, and invasion, and reduced apoptosis rates. XHC-HL-medicated serum inhibited CMA by upregulating the protein and mRNA expression of LAMP2A, HSC70, and HSP90 and downregulating substrate protein GAPDH expression via the autophagy mediated by LAMP2A. In conclusion, XHC-HL-medicated serum inhibits the proliferation, migration, and invasion of colorectal cancer cells and induces apoptosis by downregulating the expression of the key CMA molecule LAMP2A and inhibiting CMA activity.

Based on the differences in the protective effects of fresh Panax ginseng and its processed products on myocardial ischemia in mice, this study identified the advantageous aspects of fresh P. ginseng. By using network pharmacology combined with cell model validation, the molecular mechanisms of fresh P. ginseng in regulating the FoxO signaling pathway were preliminarily revealed. A mouse model of myocardial ischemia was established via intraperitoneal injection of isoproterenol hydrochloride(ISO). The comparison of the protective effects of fresh P. ginseng and its processed products on myocardial ischemia indicated that fresh P. ginseng had a more pronounced effect in reducing lipid peroxidation and alleviating myocardial ischemia in mice. On this basis, network pharmacology research was conducted, showing that fresh P. ginseng contained 19 dominant active ingredients and 38 key targets, including albumin(ALB), serine/threonine protein kinase(AKT1), epidermal growth factor receptor(EGFR), extracellular signal-regulated kinases(ERK1/2), and mitogen-activated protein kinase(P38). Fresh P. ginseng could regulate various biological functions such as cell proliferation, apoptosis, inflammation, and oxidative stress through signaling pathways including Ras, FoxO, IL-17, and Rap1, thereby protecting cardiomyocytes. Among them, the FoxO signaling pathway was identified as a characteristic pathway for fresh P. ginseng. It was further discovered that the dominant active components of fresh P. ginseng, such as ginsenoside Re, ginsenoside Rg_1, and β-elemene, could regulate this pathway through targets such as AKT, JNK, EGFR, and P38. Biological validation results showed that ginsenoside Re, ginsenoside Rg_1, and β-elemene could enhance cell viability, reduce lactate dehydrogenase(LDH) content, and decrease reactive oxygen species(ROS) levels in the cell supernatant. Target validation results indicated that ginsenoside Rg_1 and β-elemene significantly down-regulated the expression of EGFR protein in the FoxO signaling pathway, while ginsenoside Re and β-elemene significantly down-regulated the expression of ERK1/2 and P38 proteins. This study revealed the advantageous mechanisms of fresh P. ginseng in protecting against myocardial ischemia, providing a theoretical basis for the further development of fresh P. ginseng and related products.

OBJECTIVE:
To observe the protective effect and mechanism of hydroxyl safflower yellow A (HSYA) from myocardial ischemia-reperfusion injury on human umbilical vein endothelial cells (HUVECs).
METHODS:
HUVECs were treated with oxygen-glucose deprivation reperfusion (OGD/R) to simulate the ischemia reperfusion model, and cell counting kit-8 was used to detect the protective effect of different concentrations (1.25-160 µ mol/L) of HSYA on HUVECs after OGD/R. HSYA 80 µ mol/L was used for follow-up experiments. The contents of inflammatory cytokines interleukin (IL)-18, IL-1 β, monocyte chemotactic protein 1 (MCP-1), tumor necrosis factor α (TNF-α) and IL-6 before and after administration were measured by enzyme-linked immunosorbent assay. The protein expressions of toll-like receptor, NOD-like receptor containing pyrin domain 3 (NLRP3), gasdermin D (GSDMD) and GSDMD-N-terminal domain (GSDMD-N) before and after administration were detected by Western blot. NLRP3 inflammasome inhibitor cytokine release inhibitory drug 3 sodium salt (CRID3 sodium salt, also known as MCC950) and agonist were added, and the changes of NLRP3, cysteine-aspartic acid protease 1 (Caspase-1), GSDMD and GSDMD-N protein expressions were detected by Western blot.
RESULTS:
HSYA inhibited OGD/R-induced inflammation and significantly decreased the contents of inflammatory cytokines IL-18, IL-1 β, MCP-1, TNF-α and IL-6 (P<0.01 or P<0.05). At the same time, by inhibiting NLRP3/Caspase-1/GSDMD pathway, HSYA can reduce the occurrence of pyroptosis after OGD/R and reduce the expression of NLRP3, Caspase-1, GSDMD and GSDMD-N proteins (P<0.01).
CONCLUSIONS
The protective effect of HSYA on HUVECs after OGD/R is related to down-regulating the expression of NLRP3 inflammasome and inhibiting pyroptosis.
