Objective To explore a method for rapid and differential diagnosis of rejection after kidney transplantation through urine hyperspectral imaging technology. Methods Hyperspectral data information from urine samples of 118 recipients after kidney transplantation was collected, and a deep learning model was constructed to diagnose and classify the types of rejection. Results A deep learning diagnostic model based on the 34-layer residual network (ResNet-34) was constructed, and 118 patients were included and divided into the training set and the test set. Based on the pathological results of the transplanted kidney puncture, the urine samples of the patients were classified into five groups: the non-rejection group, the T-cell-mediated rejection group, the antibody-mediated rejection group, the mixed rejection group and the nephropathy recurrence group. The results showed that the diagnostic sensitivities of the model for the above five groups were 0.960, 0.980, 0.930, 0.940 and 0.943 respectively, and the diagnostic specificities were 0.983, 0.993, 0.997, 0.989 and 0.989 respectively. The overall diagnostic accuracy rate reached 95.7%. Conclusions The study provides a non-invasive, rapid and accurate auxiliary diagnostic method for the differential diagnosis of rejection after kidney transplantation.

OBJECTIVE To investigate the effects and mechanisms of Lycium ruthenicum Murr. in improving sleep. METHODS Network pharmacology was employed to identify the active components of L. ruthenicum and their associated disease targets, followed by enrichment analysis. A caffeine‑induced zebrafish model of sleep deprivation was established , and the zebrafish were treated with L. ruthenicum Murr. extract (LRME) at concentrations of 0.1, 0.2 and 0.4 mg/mL, respectively; 24 h later, behavioral changes of zebrafish and pathological alterations in brain neurons were subsequently observed. The levels of inflammatory factors [interleukin-6 (IL-6), IL-1β, IL-10, tumor necrosis factor-α (TNF-α)], oxidative stress markers [superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), catalase (CAT)], and neurotransmitters [5- hydroxytryptamine (5-HT), γ-aminobutyric acid (GABA), glutamic acid (Glu), dopamine (DA), and norepinephrine (NE)] were measured. The protein expression levels of protein kinase B1 (AKT1), phosphorylated AKT1 (p-AKT1), epidermal growth factor receptor (EGFR), B-cell lymphoma 2 (Bcl-2), sarcoma proto-oncogene,non-receptor tyrosine kinase (SRC), and heat shock protein 90α family class A member 1 (HSP90AA1) in the zebrafish were also determined. RESULTS A total of 12 active components and 176 intersecting disease targets were identified through network pharmacology analysis. Among these, apigenin, naringenin and others were recognized as core active compounds, while AKT1, EGFR and others served as key targets; EGFR tyrosine kinase inhibitor resistance signaling pathway was identified as the critical pathway. The sleep improvement rates in zebrafish of LRME low-, medium-, and high-dose groups were 54.60%, 69.03% and 77.97%, 开发。E-mail:hjp_yft@163.com respectively, while the inhibition ratios of locomotor distance were 0.57, 0.83 and 0.95, respectively. Compared with the model group, the number of resting counts, resting time and resting distance were significantly increased/extended in LRME medium- and high-dose groups (P<0.05). Neuronal damage in the brain was alleviated. Additionally, the levels of IL-6, IL-1β, TNF-α, MDA, Glu, DA and NE, as well as the protein expression levels of AKT1, p-AKT1, EGFR, SRC and HSP90AA1, were markedly reduced (P<0.05), while the levels of IL-10, SOD, GSH-Px, CAT, 5-HT and GABA, as well as Bcl-2 protein expression, were significantly elevated (P<0.05). CONCLUSIONS L. ruthenicum Murr. demonstrates sleep-improving effects, and its specific mechanism may be related to the regulation of inflammatory responses, oxidative stress, neurotransmitter balance, and the EGFR tyrosine kinase inhibitor resistance signaling pathway.

ObjectiveTo identify the multidimensional factors influencing balance dysfunction in middle-aged and older adults, providing evidence-based support for the precise identification of high-risk individuals and the formulation of fall prevention strategies. MethodsDrawing upon the 2015 follow-up data from the China Health and Retirement Longitudinal Study (CHARLS), participants aged ≥ 45 years were selected. Information on demographic characteristics, lifestyle habits, and health status was collected. Balance function was assessed using the full-tandem stance test. Logistic regression models were employed to analyze influencing factors and their correlation with Five Times Sit to Stand Test (FTSST) time. ResultsFemale (OR = 1.958, 95% CI: 1.706 to 2.247), age (OR = 1.035, 95% CI: 1.030 to 1.040), depressive state (OR = 1.151, 95% CI: 1.050 to 1.262), hypertension (OR = 1.115, 95% CI: 1.015 to 1.225), diabetes (OR = 1.587, 95% CI: 1.390 to 1.813), history of stroke (OR = 1.582, 95% CI 1.289 to 1.942), sarcopenia (OR = 1.273, 95% CI 1.080 to 1.500) and impaired activity daily living (OR = 1.306, 95% CI 1.142 to 1.493) were risk factors for balance function, while being able to complete FTSST (OR = 0.411, 95% CI 0.341 to 0.496) and having a high cognitive level (OR = 0.974, 95% CI 0.965 to 0.983) were protective factors for balance function. Among those able to complete the FTSST, longer FTSST completion time increased the risk of balance impairment after adjusting for confounding factors (Q2: OR = 1.287, 95%CI 1.116 to 1.485; Q3: OR = 1.517, 95%CI 1.321 to 1.745; Q4: OR = 1.857, 95%CI 1.615 to 2.137). ConclusionBalance function in middle-aged and older adults is influenced by multiple factors, with FTSST performance showing a significant negative correlation with balance impairment.

ObjectiveAbnormal lipids in neurons can cause the accumulation of α-synuclein(α-syn). This study aimed to explore the mechanism of Acanthopanacis Senticosi Radix et Rhizoma seu Caulis extract (ASH) in treating Parkinson's disease (PD) mice using lipidomics combined with network pharmacology. MethodsMice were divided into the blank group, model group and ASH (45.5 mg·kg-1) group. Motor ability was evaluated by pole climbing time and autonomous activity count; The oxidative stress indicators were detected by enzyme-linked immunosorbent assay (ELISA). Lipid biomarkers in brain tissues were screened and identified by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), and metabolic pathway analysis was conducted. The key targets of ASH for PD treatment were explored using network pharmacology. The Kyoto Encyclopedia of Genes and Genomes (KEGG) database was used for pathway enrichment analysis, and the "compound-reaction-enzyme-gene" network was constructed using the MetScape plugin. The protein expression levels of glutathione S-transferase P1 (GSTP1), glutathione S-transferase Mu 2 (GSTM2), prostaglandin peroxide synthase 1 (PTGS1), prostaglandin peroxide synthase 2 (PTGS2), and prostaglandin E synthase (PTGES) were validated by Western blot. ResultsCompared with the blank group, the model group showed significantly prolonged pole climbing time and reduced autonomous activity count (P<0.01). Compared with the model group, the ASH group demonstrated significantly faster pole climbing and increased autonomous activity count (P<0.01). The model group exhibited significantly decreased superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) levels, and increased malondialdehyde (MDA) level in brain tissues compared with the blank group (P<0.01). The ASH group showed increased SOD and GSH-Px levels and decreased MDA level compared with the model group (P<0.05, P<0.01). Lipidomics analysis identified 10 differential metabolites and 8 differential metabolic pathways. Network pharmacological analysis revealed 213 intersection targets between ASH components and PD, with KEGG enrichment involving the sphingolipid signaling pathway, lipid arteriosclerosis, phosphoinositide 3-kinase/protein kinase B(PI3K/Akt) signaling pathway, mitogen-activated protein kinase(MAPK) signaling pathway, and hypoxia inducible factor-1(HIF-1) signaling pathway. Integrated lipidomics and network pharmacology analysis highlighted the central role of the arachidonic acid metabolic pathway. The Western blot results showed that ASH effectively up-regulated GSTP1, GSTM2, and PTGS1 protein expression, and down-regulated PTGS2 and PTGES protein expression. ConclusionASH can ameliorate behavioral deficits, exert antioxidant effects, regulate lipid differential metabolites and the arachidonic acid metabolic pathway, thereby exerting therapeutic effects in PD model mice.

This article systematically reviews the current research status as well as diagnosis and treatment strategies of traditional Chinese medicine (TCM) for gastroesophageal reflux disease (GERD). Studies demonstrate that TCM, based on the "disease-syndrome combination" approach, exhibits multi-target advantages in alleviating symptoms of various GERD subtypes, promoting mucosal repair, regulating emotions, and facilitating the reduction of western medication. To address clinical challenges such as symptom overlap and limited therapeutic efficacy, strategies have been proposed including "treating different diseases with the same method" and integrated regulation based on viscera correlation. Future efforts should focus on elucidating the mechanisms of compound prescriptions, promoting TCM drug development under the "three-combination" evaluation framework that integrates TCM theory, human experience and clinical trial evidence, and optimizing integrated traditional and western medicine models to enhance GERD management.

AIM: To evaluate the surgical outcomes and changes in the ocular surface microenvironment following radiofrequency minimally invasive treatment for conjunctivochalasis-induced epiphora.METHODS: Patients with epiphora primarily caused by conjunctivochalasis were enrolled. All patients had conjunctivochalasis of ≥grade II, and their symptoms showed no significant improvement after previous pharmacological treatment. All patients underwent radiofrequency minimally invasive correction of conjunctivochalasis, supplemented with artificial tears, anti-inflammatory therapy, and ocular surface repair treatment postoperatively. At 8 wk post-surgery, the ocular surface disease index(OSDI), eye redness, tear secretion, non-invasive tear break-up time, lipid layer thickness, tear ferning test, and conjunctival impression cytology were assessed to compare treatment efficacy and observe changes in the ocular surface microenvironment.RESULTS: A total of 43 cases(43 eyes)of conjunctivochalasis and with a main complaint of epiphora were included, including 23 males and 20 males, with a mean age of 64.69±3.36 years. The total effective rate of surgery was 91% at 8 wk postoperatively. Compared with preoperative values, the OSDI scores significantly decreased and the non-invasive tear break-up time was prolonged at 8 wk post-surgery(all P<0.05). No statistically significant differences were observed in lipid layer thickness or tear secretion at 8 wk postoperatively(all P>0.05). The normal rate of chloramphenicol taste test increased from 21% preoperatively to 63% postoperatively; the normal rate of eye redness increased from 40% to 70%; normal rate of tear ferning grading improved from 30% to 63%; and normal conjunctival impression cytology grading increased from 21% to 74%.CONCLUSION: Radiofrequency minimally invasive treatment is effective for conjunctivochalasis and is straightforward to perform. Patients with conjunctivochalasis often present with other ocular surface issues beyond conjunctivochalasis itself, such as insufficient tear secretion, reduced lipid layer thickness, and other dry eye-related problems. Therefore, a comprehensive approach emphasizing tear dynamics should be adopted during treatment.

Objective To analyze the epidemiological characteristics of statutory infectious diseases in Yichang City from 2015 to 2023 and evaluate the effectiveness of non-pharmaceutical interventions (NPIs) in infectious disease prevention and control, and to provide a basis for formulating prevention and control strategies. Methods Descriptive epidemiological methods were used to analyze annual incidence rates. SARIMA and SARIMA intervention models were constructed to predict the incidence rates of infectious diseases. Interrupted time series analysis (ITS) was applied to assess the control effectiveness. Results The average annual incidence rate from 2015 to 2023 was 787.47/100 000, with the top five diseases being influenza, hand-foot-and-mouth disease, hepatitis B, tuberculosis, and diarrheal diseases. The average incidence rate from 2015 to 2019 (654.31/100 000) was significantly higher than that from 2020 to 2022 (489.01/100 000) (χ2= 3 499.6, P < 0.05). The total incidence rate in 2023 (2 396.51/100 000) was significantly higher than the average annual incidence rates from 2015-2019 (χ2= 108 186.1, P < 0.05) and 2020-2022 (χ2= 112 869.4, P < 0.05). SARIMA model results indicated that the actual incidence rate from 2020 to 2022 decreased by 73.49% compared to the predicted rate without intervention, with the highest decline observed in respiratory infectious diseases (79.57%). The SARIMA-intervention model showed a 55.48% relative decrease in the total incidence rate for 2023, with the largest reduction in respiratory infectious diseases (63.28%) and a slight increase in intestinal infectious diseases (5.48%). Conclusion NPIs effectively reduce the incidence of statutory infectious diseases in the short term, especially for acute respiratory and intestinal infectious diseases. However, long-term effectiveness faces challenges, necessitating the development of differentiated prevention and control strategies.

ObjectiveTo investigate the characteristics of gray matter structure and clinical symptoms in patients with Alzheimer's disease (AD) comorbid with apathy (AD-A). MethodsThe study included 30 patients with AD-A, 30 AD disease patients without apathy (AD without apathy, AD-NA), and 30 healthy controls (HCs) matched in gender, age, and years of education. All participants underwent a comprehensive neuropsychological assessment and magnetic resonance imaging (MRI) scans. Voxel-based morphometry (VBM) was used to analyze changes in gray matter volume among the three groups. Additionally, the correlation between the identified abnormal brain regions and apathy scale scores was analyzed. ResultsThere were no statistically significant differences among the three groups in terms of age, gender, years of education, or total intracranial volume. Compared with the HCs group, both the AD-A and AD-NA groups showed significantly lower scores in cognitive function (P<0.001). The AD-A group exhibited significantly higher apathy scale scores compared with the AD-NA group (P<0.001). Compared with the AD-NA group, the AD-A group showed reduced gray matter volume in the bilateral caudate nucleus, left orbitofrontal cortex, lingual gyrus, inferior frontal gyrus, superior frontal gyrus, entorhinal cortex, right middle frontal gyrus and posterior cingulate cortex (FWE-corrected, P<0.05 for all). Compared with the HCs group, the AD-A group exhibited reduced gray matter volume in the bilateral middle temporal gyrus, left fusiform gyrus, calcarine sulcus, postcentral gyrus, right inferior frontal gyrus and supramarginal gyrus (FWE-corrected, P<0.05 for all). Compared with the HCs group, the AD-NA group showed reduced gray matter volume in the left precuneus, inferior temporal gyrus, and right inferior temporal gyrus (FWE-corrected, P<0.05 for all). In the AD-A group, changes in the gray matter volume of the left caudate nucleus (r= -0.557, P=0.002) and right middle frontal gyrus (r=-0.620, P=0.001) were negatively correlated with the apathy evaluation scale (AES) scores. ConclusionPatients in the AD-A group exhibited significant atrophy in the frontal-temporal-basal ganglia circuit, and the degree of gray matter atrophy was correlated with the severity of apathy.

OBJECTIVE To compare the efficacy and safety of evolocumab and probucol in patients with ultra-high-risk atherosclerotic cardiovascular disease (ASCVD) following percutaneous coronary intervention (PCI). METHODS A retrospective analysis was conducted on 156 ultra-high-risk ASCVD patients who underwent PCI in our institution between January 1, 2023 and December 31, 2024. According to the lipid-lowering regimen, the patients were categorized into evolocumab group ( n =86) and probucol group ( n =70). Changes in lipid parameters [total cholesterol (TC), low-density lipoprot ein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides, lipoprotein (a), and lipid goal achievement rate ] , inflammatory markers [interleukin-6 (IL-6) and C-reactive protein (CRP) ] , and cardiac function indices (left ventricular ejection fraction, left ventricular end-systolic diameter, left ventricular end-diastolic diameter, and N-terminal pro-B-type natriuretic peptide) were compared between two groups at baseline and after 6 months of treatment. The incidence of adverse clinical events during treatment, including acute myocardial infarction, in-stent restenosis, acute heart failure, cerebral hemorrhage, and stroke, was also evaluated. RESULTS No statistically significant differences were observed between the two groups at baseline ( P >0.05). After 6 months of treatment, both groups demonstrated significant improvements in lipid profiles (except HDL-C) and inflammatory markers compared to those at baseline ( P <0.05). The evolocumab group exhibited greater reductions in TC, LDL-C, IL-6, and CRP, along with a higher lipid target achievement rate, compared with the probucol group ( P <0.05). There were no statistically significant differences in the cardiac function-related indicators before and after treatment between the two groups, nor in the incidence of adverse events during the treatment ( P >0.05). CONCLUSIONS For ultra-high-risk ASCVD patients after PCI, both of the above treatment options are associated with improvements in blood lipid and inflammatory response, with good safety during short-term follow-up. Evolocumab shows superior efficacy in TC, LDL-C and inflammatory markers reduction and lipid target achievement, compared to probucol.

Objective To investigate the protective effect and underlying mechanism of human umbilical cord mesenchymal stem cell-derived exosomes (hucMSC-Exo) on renal ischemia-reperfusion injury (IRI). Methods hucMSC-Exos were isolated and characterized. A mouse renal IRI model was established and the animals were divided into Sham, IRI, IRI+hucMSC-Exo, IRI+hucMSC-Exo+JY-2 and Sham+JY-2 groups. Serum creatinine (Scr) and blood urea nitrogen (BUN) were measured. Hematoxylin-eosin (HE) staining was used to evaluate renal histopathology. Enzyme-linked immune absorbent assay was performed to determine serum interleukin (IL)-1β and IL-18 levels. Western blotting was used to detect the expression of activating transcription factor 3 (ATF3), Toll-like receptor 4 (TLR4), nuclear factor (NF)-κB, NOD-like receptor protein 3 (NLRP3), cysteineyl aspartate specific proteinase (Caspase)-1 p20 and Gasdermin D(GSDMD). Real-time fluorescent quantitative polymerase chain reaction was employed to measure ATF3, TLR4 and NF-κB messenger RNA (mRNA). Immunohistochemistry was conducted to examine NLRP3, Caspase-1 p20 and GSDMD. An in vitro hypoxia/reoxygenation (H/R) model was established in HK-2 cells and divided into Control, H/R, H/R+hucMSC-Exo, H/R+hucMSC-Exo+JY-2 and Control+JY-2 groups. Western blotting was used to detect the expression of ATF3, TLR4 and NF-κB. Real-time fluorescent quantitative polymerase chain reaction was used to measure NLRP3, GSDMD and Caspase-1 mRNA. Results HucMSC-Exos were successfully isolated and identified. Compared with the Sham group, the IRI group exhibited elevated Scr and BUN, higher tubular injury scores, increased protein expression levels of ATF3, TLR4, NF-κB p65, NLRP3, Caspase-1 p20 and GSDMD, and raised mRNA expression levels of ATF3, TLR4, NF-κB. Compared with the IRI group, the IRI+hucMSC-Exo group showed decreased Scr and BUN, lower tubular injury scores, up-regulated ATF3 protein and mRNA, down-regulated TLR4, NF-κB p65, NLRP3, Caspase-1 p20 and GSDMD protein, and declined TLR4 and NF-κB mRNA. Compared with the IRI+hucMSC-Exo group, the IRI+hucMSC-Exo+JY-2 group exhibited increased Scr and BUN levels, elevated renal tubular injury scores, decreased ATF3 protein expression levels, elevated protein expression levels of TLR4, NF-κB p65, NLRP3, Caspase-1 p20, and GSDMD, decreased ATF3 mRNA expression levels, and elevated mRNA expression levels of TLR4 and NF-κB. (all P < 0.05). Compared with the Control group, the expression levels of ATF3, TLR4 and NF-κB p65 proteins were increased in the H/R group, and the expression levels of NLRP3, Caspase-1 and GSDMD mRNA were increased. Compared with the H/R group, the expression level of ATF3 protein was increased, the expression levels of TLR4 and NF-κB p65 proteins were decreased, and the expression levels of NLRP3, Caspase-1 and GSDMD mRNA were decreased in the H/R+hucMSC-Exo group. Compared with the H/R+hucMSC-Exo group, the expression level of ATF3 protein was decreased, the expression levels of TLR4 and NF-κB p65 proteins were increased, and the expression levels of NLRP3, Caspase-1 and GSDMD mRNA were increased in the H/R+hucMSC-Exo+JY-2 group (all P < 0.05). Conclusions HucMSC-Exos alleviate renal IRI by up-regulating ATF3, thereby negatively regulating the TLR4/NF-κB signaling pathway and subsequently inhibiting pyroptosis.
