ObjectiveTo investigate the role of the Toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear factor-κB （NF-κB） signaling pathway in intestinal mucosal barrier damage in ulcerative colitis， as well as the intervention mechanism of Shaoyaotang. MethodsSixty SD rats were allocated into a blank group， a model group， a mesalazine （0.42 g·kg^-1） group， and low-， medium-， and high-dose （11.1， 22.2， 44.4 g·kg^-1， respectively） Shaoyaotang groups. A model of ulcerative colitis was induced by 2，4，6-trinitrobenzenesulfonic acid （TNBS）. After successful modeling， rats were administrated with corresponding agents via gavage for 7 days. Changes in colon length and colon weight were observed. Hematoxylin-eosin staining was performed to examine the pathological changes of the colon， and immunohistochemistry was employed to detect the expression of the inflammatory cytokine interleukin-8 （IL-8）， cyclooxygenase-2 （COX-2）， junction adhesion molecule-1 （JAM-1）， and claudin-1 in the colon. Western blot analysis was performed to determine the protein levels of TLR4， MyD88， and NF-κB in the colon. ResultsCompared with the blank group， the model group showed elevated DAI score （P<0.01）， reduced colon length and colon weight （P<0.01）， down-regulated protein levels of JAM-1 and claudin-1 （P<0.01）， and up-regulated protein levels of IL-8， COX-2， TLR4， MyD88， and NF-κB p65 （P<0.01） in the colon tissue. Compared with the model group， each treatment group showed decreased DAI score （P<0.05， P<0.01）， increased colon length and colon weight （P<0.05， P<0.01）， up-regulated protein levels of JAM-1 and claudin-1 （P<0.01）， and down-regulated protein levels of IL-8， COX-2， TLR4， MyD88， and NF-κB p65 （P<0.01） in the colon tissue. ConclusionShaoyaotang alleviates intestinal inflammation and intestinal mucosal damage to protect intestinal barrier integrity by regulating the TLR4/MyD88/NF-κB signaling pathway.

Systemic lupus erythematosus （SLE） may lead to secondary gynecological and obstetric disorders such as decreased ovarian reserve function， menstrual abnormalities， and adverse pregnancy outcomes. Based on "bi （痹） of both body and viscera" theory， this paper proposed that the core mechanism of SLE secondary gynecological and obstetric diseases lies in the mutual transformation between "body bi" and "viscera bi"， which together affect the uterus. Physiologically， uterus forms an internal-external network with the body and viscera through the meridians and blood vessels. Pathologically， when the healthy qi is deficient， nourishment of the body and viscera is impaired； when toxins and stasis accumulate， pathogenic factors disturb the uterus through the chong （冲） and ren （任） meri-dians. The resulting obstruction in the uterus can， in turn， manifest externally and aggravate damage to the body and viscera. Therefore， the pathogenesis of SLE secondary gynecological and obstetric diseases follows a dynamic trajectory of "body bi first， body bi affecting viscera， and then bi of both body and viscera". In treatment， the principle of harmonizing and balancing the healthy qi is emphasized. The main approach is to regulate the viscera， stabilize the body， and nourish the uterus， with the coordination of nourishing the viscera through the body， thereby achieving simultaneous treatment of both body and viscera. This highlights the guiding significance of the "bi of both body and viscera" theory in preventing and treating SLE secondary gynecological and obstetric diseases.

mechanism.Methods:Thirty Wistar rats were selected and the precancerous liver lesion model was established using the modified Solt-Faber method.The rats were randomly divided into sham operation group,model group,and IGBR group,and there were 10 rats in each group.The morphology of liver tissue of the rats in various groups were observed;the liver weights,liver indexes and liver regeneration degrees of the rats in various groups were measured;HE staining was used to observe the pathomorphology of liver tissue of the rats in various groups;immunohistochemistry method was used to detect the expression of glutathione-S-transferase(GST)-Pi protein in liver tissue of the rats in various groups;colorimetric method was used to detect the activities of γ-glutamyl transpeptidase(γ-GT),catalase(CAT),superoxide dismutase(SOD),glutathione peroxidase(GSH-Px)and glutathione S-transferase(GST),and the level of malondialdehyde(MDA)in liver tissue and mitochondria of the rats in various groups;Western blotting method was used to detect the expression levels of α-smooth muscle actin(α-SMA),collagen type Ⅰ alpha 1 chain(ColⅠα1),matrix metalloproteinase(MMP)13,MMP2,tissue inhibitor of metalloproteinase(TIMP)1,TIMP2,transforming growth factor β1(TGF-β1),TGF-β1 receptor(TβR),mothers against decapentaplegic homolog(Smad)2/3,Smad4,and Smad7 proteins in liver tissue of the rats in various groups.Results:Compared with sham operation group,the liver weight,liver index and degree of liver regeneration of the rats in model group were increased(P<0.05);compared with model group,the liver weight and liver index of the rats in IGBR group showed a decreasing trend,but the difference was not statistically significant(P>0.05).The HE staining results showed that the liver lobule structure in sham operation group was intact and clear,with large hepatocytes,abundant eosinophilic cytoplasm,and hepatocytes arranged in single cords radiating from the central vein;there were irregular hepatic sinusoids between plates,with only a small amount of collagen fibers and inflammatory cell infiltration in the portal area,and no degeneration or necrosis of hepatocytes.In model group,the normal arrangement of hepatocytes disappeared,the liver lobule structure was disrupted,small cell hyperplasia(mainly oval cells)was observed in the portal area,with massive collagen deposition and significant fibrous tissue hyperplasia in the fibrous septum;hepatocytes showed extensive degenerative edema,hydropic degeneration or even ballooning degeneration and focal necrosis;basophilic hepatocytes formed proliferative areas with clear cytoplasm,centrally located nuclei and 1-2 prominent nucleoli;glassy hepatocytes with enlarged nuclei and pale transparent cytoplasm were also observed.In IGBR group,the liver lobule structure was basically preserved,with reduced inflammatory lesions,mild edema,and scattered spotty or focal necrosis;nuclear atypia and pathological mitotic figures or binucleation were observed.The immunohistochemistry results showed GST-Pi protein positive foci with brown-yellow cytoplasmic staining in round or oval nodules.The GST-Pi protein positive foci were observed in liver tissue of the rats in model group,indicating successful establishment of precancerous liver lesion model.The scattered GST-Pi protein positive foci were observed in IGBR group,which were significantly reduced compared with model group.Compared with sham operation group,the activity of γ-GT in liver tissue of the rats in model group was increased(P<0.05);compared with model group,the activity of γ-GT in liver tissue of the rats in IGBR group was decreased(P<0.05).Compared with sham operation group,the GST activity and MDA level in liver tissue and liver mitochondria of the rats in model group were increased(P<0.05),while the activities of SOD,CAT,and GSH-Px were decreased(P<0.05);compared with model group,the GST activity and MDA level in liver tissue and liver mitochondria of the rats in IGBR group were decreased(P<0.05),while the activities of SOD,CAT,and GSH-PX were increased(P<0.05).The Western blotting results showed that compared with sham operation group,the expression levels of α-SMA,ColⅠα1,TIMP1,and TIMP2 proteins in liver tissue of the rats in model group were increased(P<0.05),while the expression levels of MMP13 and MMP2 proteins were decreased(P<0.05),and the ratios of TIMP1/MMP13 and TIMP2/MMP2 were increased(P<0.05);compared with model group,the expression levels of α-SMA,ColⅠα1,and TIMP2 proteins in liver tissue of the rats in IGBR group were decreased(P<0.05),while the expression levels of MMP13 and MMP2 proteins were increased(P<0.05),and the ratios of TIMP1/MMP13 and TIMP2/MMP2 were decreased(P<0.05).Compared with sham operation group,the expression levels of TGF-β1 and Smad2/3 proteins in liver tissue of the rats in model group were increased(P<0.05);compared with model group,the expression levels of TGF-β1,Smad2/3 and Smad 4 proteins in liver tissue of the rats in IGBR group were decreased(P<0.05).Conclusion:IGBR can inhibit precancerous liver lesions and liver fibrosis in rats,and its mechanism may be related to enhancing the antioxidant capacity of liver tissue,inhibiting TGF-β/Smad signaling pathway and regulating TIMP/MMP balance.

A colorimetric detection method for xanthine oxidase activity and its inhibitors(XOI)based on nitrogen-doped carbon-supported ruthenium metal atom(Ru/NC)nanozyme was developed.Through a host-guest strategy,Ru/NC nanozyme with excellent peroxidase-like activity was prepared using zeolitic imidazolate framework-8(ZIF-8)as the host molecule and ruthenium acetylacetonate(Ru(acac)3)as the guest molecule.Based on its peroxidase-like catalytic activity,the visual method for detection of hydrogen peroxide(H 2O 2)and analysis of xanthine oxidase(XO)activity were developed.Under optimized experimental conditions,the linear detection range for H 2O 2 was 10-500 μmol/L,with a detection limit of 4.8 μmol/L(3σ);for XO activity analysis,the linear range was 1-7 mU/mL,with a detection limit of 0.69 mU/mL(3σ).Furthermore,an effective method for screening XOI was developed,which had the advantages of low cost,simplicity,and visualization.

Detection of poor-water-soluble substances typically requires an organic solvent containing solution,and therefore,the biosensors that can operate in such conditions are highly promising for practical applications.However,most existing biosensors have been developed in aqueous solution and it is hard to work effectively in organic solvent systems.In this work,we uncovered that the G-quadruplex(G4)/hemin DNAzyme(G4HD)could be strongly reactivated by NH4 in organic solvents at concentration up to 30％,and the activity was significantly higher than that in aqueous solutions containing K+.Based on this discovery,a biosensing system was developed for small molecule in 40％methanol by coupling G4HD with our previously identified RNA-cleaving DNAzyme(E3).This system comprised an ATP-activated aptazyme that was made of E3 and a G4HD that was activated by the cleavage product of the aptazyme.By using a manmade pipette tip filter to separate the reaction products,the subsequent colorimetric reaction of the G4HD could be triggered.This biosensing system enabled the visualization of target molecules in organic cosolvents without any other instruments.The activable DNAzyme-cascade sensing system had potential in point-of-care detection of poor-water-soluble pollutants,thereby enhancing the practical values of functional nucleic acid-based biosensors in real-world detection conditions.

Aim To study the mechanism of salidro-side combined with rosavin in rats with ischemic stroke.Methods The MCAO rats was established by using thread-embolic method.The rats were divided into the sham group,MCAO group,salidroside com-bined with rosavin group,and positive control group;the drug was given continuously for seven days.Western blot was used to detect apoptosis indicators.Proteomics was used to analyse differential proteins(DEPs).STEP receptor inhibitor was injected into the lateral ventricles,the rats were administered for seven days,then the apoptosis indicators were detected.Re-sults Salidroside combined with rosavin could reduce neurological function scores in MCAO rats and inhibit cell apoptosis.Quantitative proteomics identified 496 DEPs in brain tissue and discovered core proteins STEP,p38,and CRTC1.Salidroside combined with rosavin could promote the STEP and CRTC1 while in-hibiting p38 protein.After treatment with STEP inhibi-tor,those effects were reversed.Conclusion Salidro-side combined with rosavin can inhibit cell apoptosis in MCAO rats,which is closely related to the regulation of the STEP/p38/CRTC1 signaling pathway.

ObjectiveTo investigate the influence of histone deacetylase 3 (HDAC3) on the occurrence, development of psoriasis-like inflammation in mice, and the relative immune mechanisms. MethodsHealthy C57BL/6 mice aged 6-8 weeks were selected and randomly divided into 3 groups: control group (Control), psoriasis model group (IMQ), and HDAC3 inhibitor RGFP966-treated psoriasis model group (IMQ+RGFP966). One day prior to the experiment, the back hair of the mice was shaved. After a one-day stabilization period, the mice in Control group was treated with an equal amount of vaseline, while the mice in IMQ group was treated with imiquimod (62.5 mg/d) applied topically on the back to establish a psoriasis-like inflammation model. The mice in IMQ+RGFP966 group received intervention with a high dose of the HDAC3-selective inhibitor RGFP966 (30 mg/kg) based on the psoriasis-like model. All groups were treated continuously for 5 d, during which psoriasis-like inflammation symptoms (scaling, erythema, skin thickness), body weight, and mental status were observed and recorded, with photographs taken for documentation. After euthanasia, hematoxylin-eosin (HE) staining was used to assess the effect of RGFP966 on the skin tissue structure of the mice, and skin thickness was measured. The mRNA and protein expression levels of HDAC3 in skin tissues were detected using reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR) and Western blot (WB), respectively. Flow cytometry was employed to analyze neutrophils in peripheral blood and lymph nodes, CD4⁺ T lymphocytes, CD8⁺ T lymphocytes in peripheral blood, and IL-17A secretion by peripheral blood CD4⁺ T lymphocytes. Additionally, spleen CD4⁺ T lymphocyte expression of HDAC3, CCR6, CCR8, and IL-17A secretion levels were analyzed. Immunohistochemistry was used to detect the localization and expression levels of HDAC3, IL-17A, and IL-10 in skin tissues. ResultsCompared with the Control group, the IMQ group exhibited significant psoriasis-like inflammation, characterized by erythema, scaling, and skin wrinkling. Compared with the IMQ group, RGFP966 exacerbated psoriasis-like inflammatory symptoms, leading to increased hyperkeratosis. The psoriasis area and severity index (PASI) skin symptom scores were higher in the IMQ group than those in the Control group, and the scores were further elevated in the IMQ+RGFP966 group compared to the IMQ group. Skin thickness measurements showed a trend of IMQ+RGFP966>IMQ>Control. The numbers of neutrophils in the blood and lymph nodes increased sequentially in the Control, IMQ, and IMQ+RGFP966 groups, with a similar trend observed for CD4⁺ and CD8⁺ T lymphocytes in the blood. In skin tissues, compared with the Control group, the mRNA and protein levels of HDAC3 decreased in the IMQ group, but RGFP966 did not further reduce these expressions. HDAC3 was primarily located in the nucleus. Compared with the Control group, the nuclear HDAC3 content decreased in the skin tissues of the IMQ group, and RGFP966 further reduced nuclear HDAC3. Compared with the Control and IMQ groups, RGFP966 treatment decreased HDAC3 expression in splenic CD4⁺ and CD8⁺ T cells. RGFP966 treatment increased the expression of CCR6 and CCR8 in splenic CD4⁺ T cells and enhanced IL-17A secretion by peripheral blood and splenic CD4⁺ T lymphocytes. Additionally, compared with the IMQ group, RGFP966 reduced IL-10 protein levels and upregulated IL-17A expression in skin tissues. ConclusionRGFP966 exacerbates psoriatic-like inflammatory responses by inhibiting HDAC3, increasing the secretion of the cytokine IL-17A, and upregulating the expression of chemokines CCR8 and CCR6.

Objective:To explore the design and application effect of a home-based pulmonary rehabilitation checklist for postoperative lung cancer patients and to analyze the feasibility of this innovative rehabilitation approach.Methods:A prospective non-concurrent controlled study was conducted. Eighty postoperative lung cancer patients from the Department of Thoracic Surgery, Henan Provincial People's Hospital, were conveniently selected. According to the time of admission, postoperative lung cancer patients from April to June 2024 ( n=40) were assigned to the control group, while those postoperative lung cancer patients from August to October 2024 ( n=40) were assigned to the experimental group. The control group was given routine home-based pulmonary rehabilitation knowledge education upon discharge, while the experimental group was provided with the application of a home-based pulmonary rehabilitation checklist in addition to the routine home-based pulmonary rehabilitation knowledge education. Assessments were performed on the day of discharge and 1-month post-discharge using the Chinese version-Strategies Used by People to Promote Health (C-SUPPH), the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC-QLQ-C30), the six-minute walk test (6MWT) and the Brog score. Results:A total of 40 patients in each group completed this study. Among them, there were 26 males and 14 females in the control group, aged (51.25 ± 11.39) years, and 23 males and 17 females in the experimental group, aged (53.07 ± 12.21) years. One month after discharge, the scores of positive attitude, self-decision making and self-stress reduction on the C-SUPPH in the experimental group were (44.25 ± 10.29), (30.76 ± 8.31) and (9.51 ± 2.17) points, respectively. They were higher than those in the control group (37.02 ± 7.14), (26.61 ± 6.71) and (7.58 ± 1.09) points, and the differences were statistically significant ( t=-3.65, -2.46, -5.03, all P<0.05). The scores of somatic function, role function, cognitive function and emotional function on the EORTC-QLQ-C30 in the experimental group were (65.77 ± 6.41), (71.46 ± 7.21), (70.11 ± 5.61) and (69.59 ± 5.71) points, respectively. They were higher than those in the control group (57.71 ± 7.01), (64.27 ± 5.25), (62.79 ± 7.18), (61.11 ± 6.25) points, and the differences were statistically significant ( t values were -6.34 to -5.08, all P<0.05). The 6MWT distance in the experimental group was (411.31 ± 35.02) m, which was higher than (376.58 ± 30.26) m in the control group, and the difference was statistically significant ( t=-4.75, P<0.05). The Brog score in the experimental group was (2.12 ± 0.68) points, which was lower than (2.50 ± 0.65) points in the control group, and the difference was statistically significant ( t=2.56, P<0.05). Conclusions:The implementation of home pulmonary rehabilitation list can improve the self-management ability of patients after lung cancer surgery, improve the quality of life, and then enhance the exercise ability, which is worthy of clinical promotion.

Suppressor of cytokine signaling 3(SOCS3),a member of SOCS family,plays a major role in cell signaling trans-duction.SOCS3 is important in regulation of immune homeostasis and also involved in the control of energy metabolism,mainly through regulating JAK/STAT pathway.Recent studies have shown that SOCS3 was closely associated with glycolipid metabolic diseases like diabetes and obesity,and can be used as a new target for treatment of these glycolipid metabolic diseases.This review focuses on the latest research progress of the role and mechanism of SOCS3 in glycolipid metabolic diseases,and discusses the possibility of SOCS3 as a therapeutic target for glycolipid metabolic diseases.

Objective This study aimed to investigate the correlation of cerebral perfusion and cognitive function status in patients with minor stroke(MS)or transient ischemic attack(TIA)complicated by severe intracranial arterial stenosis or occlusion(hereafter referred to as ICAS-MSTIA).Methods Retrospectively enrol consecutive ICAS-MSTIA patients admitted to the Department of Neurology,the First Affiliated Hospital of Xi'an Jiaotong University,from June 2023 to May 2024.In the meantime,healthy controls were openly recruited.The ICAS-MSTIA patients were divided into two groups based on the side of intracranial large artery stenosis or occlusion:the left intracranial large artery involvement group and the right intracranial large artery involvement group.All patients with intracranial large artery stenosis or occlusion underwent MR scanning within 2 weeks after the first episode of TIA or MS,while there was no specific time requirement for MR examination in the healthy control group.On the day of MR scanning,the Montreal cognitive assessment(MoCA)scale was used to evaluate the participants'global cognitive function and performance in various cognitive domains,including visuospatial/executive function,naming,attention,language,abstraction,delayed recall,and orientation.General information of all participants was collected,including age,sex,educational level,body mass index,and history of smoking and alcohol consumption.Clinical data were collected from both left and right intracranial large artery involvement groups,including cerebrovascular risk factors(such as,diabetes mellitus,hypertension,and hyperlipidemia),National Institutes of Health stroke scale(NIHSS)score at admission,responsible stenotic or occluded arteries(internal carotid artery,middle cerebral artery),degree of stenosis in the responsible vessel(severe stenosis[stenosis rate 70%-99%],occlusion[stenosis rate100%])and non-responsible vessel(no stenosis[0],mild stenosis[stenosis rate＞0-49%]),collateral circulation compensation(American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology[ASTIN/SIR]collateral circulation classification),and responsible events(TIA,MS).General data and MoCA scale scores were compared across the three groups,while clinical data were compared between the left and right intracranial large artery involvement groups.Statistical parametric mapping 12(SPM 12)was used to perform voxel-wise independent samples t-tests on cerebral blood flow(CBF)differences among the left ICAS-MSTIA group,right ICAS-MSTIA group,and healthy control group,with cluster-level family-wise error(FWE)correction applied for adjustment.Multiple linear regression analysis was conducted to evaluate the relationship between global CBF values and total MoCA scores in ICAS-MSTIA patients with left or right intracranial large artery involvement.Results A total of 33 ICAS-MSTIA patients and 33 healthy controls were enrolled in the study.Among the ICAS-MSTIA patients,21 had left intracranial large artery involvement and 12 had right involvement.(1)Among the three groups,statistically significant differences were observed in the proportions of individuals with reported smoking history(P=0.024)and alcohol consumption history(P=0.011).The left intracranial large artery involvement group had a higher NIHSS score(0[0,2]vs.0[0,0],P=0.044)and a higher proportion of patients with internal carotid artery involvement(13/21 cases vs.2/12 cases,P=0.027)compared with the right side group.No statistically significant differences were observed in other general or clinical data across the three groups or between the two non-control groups(all P＞0.05).(2)Statistically significant differences were found across the three groups in the MoCA scale total score and scores of visuospatial/executive function,attention,language,abstraction,delayed recall,and orientation cognitive domains(all P＜0.05),while no significant difference was noted in the naming score(P=0.063).The left intracranial large artery involvement group had lower total MoCA score and lower scores in visuospatial/executive function,attention,language,abstraction,delayed recall,and orientation in comparison to the healthy control group(all P＜0.016 7).The right intracranial large artery involvement group had significantly lower scores in language,abstraction,and orientation domains than the healthy control group(all P＜0.016 7).Additionally,the left side group had a lower attention domain score than the right side group(P＜0.016 7).No other statistically significant differences were found in pairwise comparisons(all P＞0.016 7).(3)Patients in both the left and right intracranial large artery involvement groups exhibited a significant decrease in CBF in extensive regions on the affected side,including the temporal lobe,dorsolateral prefrontal cortex,and occipital lobe.Furthermore,after correction,in the left involvement group CBF was higher in the contralateral lingual gyrus,cuneus,and calcarine sulcus compared with the healthy control group(P＜0.05).While in the right involvement group,no regions had increased CBF compared to the healthy control group.(4)Multiple linear regression showed positive correlation between CBF in ipsilateral precentral gyrus and superior temporal gyrus,and the total MoCA score in patients with left intracranial large artery involvement(FWE-corrected,P＜0.05).In contrast,there was no correlation between CBF and total MoCA score in patients with right intracranial large artery involvement.Conclusions ICAS-MSTIA patients exhibited various degrees of impairment in cerebral perfusion and cognitive function.A significant positive correlation is observed between these two impairments in patients with left intracranial large artery involvement.
