Osteopontin(OPN)is a multifunctional protein,widely distributed in a variety of cells,tissues,organs and body fluids.This protein has a classical RGD domain and can bind to a variety of integrins and CD44 receptors,thereby participating in various pathological processes in the body,such as infection,allergic reaction,autoimmune and tissue damage.Recently,many studies have revealed that OPN is highly expressed in the central nervous system(CNS)and plays different regulatory roles in CNS diseases,that is,OPN can play a pro-inflammatory role in some conditions to stimulate neurotoxicity,while it can play a neuroprotective role in other conditions.While there has been growing interest in the biological role of OPN in the CNS,a comprehensive review is currently lacking.The purpose of this paper is to provide an overview of the expression and function of OPN in the CNS,with a focus on microglia,astrocytes,and neurons.

Aim To reveal the mechanism of CIP4 homologs protein 1(RICH1)are involved in the regu-lation of myocardial fibrosis.Methods Mouse cardiac fibroblasts(MCFs)cells were treated with transforming growth factor-β(TGF-β1)to induce the formation of a myocardial fibrosis cell model;the level of the target protein was detected by Western blotting;and the RICH1 gene was detected by transfection of the cells with plasmid.The RICH1 gene was overexpressed(RICH 1 OE)using plasmid transfection;the RICH1 gene was silenced using siRNA fragment(siRICH1);and the expression levels of myocardial fibrosis marker genes,such as Col1 a1,Col3 a1,and Acta2,were de-tected using RT-qPCR.Results RICH1 was signifi-cantly down-regulated in TGF-β1-treated MCFs;the expression levels of myocardial fibrosis marker genes,such as Col1 a1,Col3a1,and Acta2,were down-regu-lated in the RICH1 OE+TGF-β1 group;and in the siRICH1+TGF-β1 group,myocardial fibrosis marker genes,such as Col1 a1,Col3a1 and Acta2 were up-regulated at the expression level;phosphorylated SMAD2(p-SMAD2)and phosphorylated SMAD3(p-SMAD3)levels were down-regulated in the siRICH1 OE+TGF-β1 group.p-SMAD2 and P-SMAD3 levels were upregulated in the siRICH1+TGF-β1 group.Conclusion RICH1 inhibits TGF-β1-induced myo-cardial fibrosis;RICH1 inhibits TGF-β1-induced myo-cardial fibrosis by negatively regulating the SMAD2/3 signaling pathway.

Objective:To explore the application effect of integrated traditional Chinese and Western medicine nursing based on"whole course case management mode"in patients with coronary heart disease(CHD)after percutaneous coronary inter-vention(PCI).Methods:This randomized controlled study enrolled 98 CHD patients who underwent PCI for the first time at Jiangsu Province Hospital of Chinese Medicine between February 2022 and May 2023.The patients were divided into in-tervention group(n=49)and control group(n=49).The patients in intervention group received whole course case man-agement model-based integrated traditional Chinese and Western medicine nursing plan,while those in the control group received routine nursing care after PCI.Scores of Morisky Medication Adherence Scale(MMAS-8),Cardiovascular Health Score(CHS),China questionnaire of quality of life in patients with cardiovascular diseases(CQQC)and incidence of adverse cardiac events were compared between two groups after 6 and 12 months.Results:Compared with patients in control group after intervention,those in intervention group had significant higher scores of MMAS-8[6 months:(6.63±0.83)points vs.(5.96±0.95)points,12 months:(6.85±0.96)points vs.(5.84±0.91)points],CHS[(8.10±1.37)points vs.(7.45±1.28)points],CQQC[(92.73±7.44)points vs.(88.16±2.88)points],and significant lower incidence of adverse cardiac events(14.29％vs.36.73％)(P＜0.05 or＜0.01).Conclusion:The integrated traditional Chinese and Western medicine nursing intervention plan based on the whole course case management model could effectively improve medication compliance,strengthen cardiovascular health behavior,reduce the incidence of adverse cardiac events,and improve quality of life in CHD patients after PCI.

This study investigated the infection status,drug resistance,and molecular characteristics of Shiga toxin-producing Escherichia coli(STEC)in domestic goats in Chengkou county,Chongqing.In August 2023,283 fecal samples were collected from households in Chengkou county.After enrichment with EC broth and inoculation onto selective media,samples that tested positive for stx1/stx2 were selected for further isolation.The positive strains were investigated with antimicrobial susceptibility testing and whole genome sequencing.According to the whole genomic sequences,the stx subtypes,serotypes,multi-locus sequence types,virulence genes,drug resistance genes,and phylogenetic relationships of the STEC strains were analyzed.Forty-six strains of STEC were isolated from 283 goat fecal samples,thus resulting in a detection rate of 16.25%.The 46 STEC strains were categorized into 12 O∶H serotypes,among which O76∶H19 and O8∶H7 predominated,each represented by 9 strains.Five STEC strains were identified as serotype O157∶H7.The 46 STEC strains were categorized into 11 sequence types(STs),among which ST675 and ST196 predominated,each represented by nine strains,accounting for a 19.57%proportion.The strains were categorized into 7 stx subtypes,among which stx1c(26/46,56.52%),followed by stx2k(9/46,19.57%)predominated.All nine Stx2k-STEC strains were identified as serotype O8∶H7 and sequence type ST196.In antimicrobial susceptibility testing,2 STEC strains were resistant to ampicillin,one strain was resistant to ampicillin/sulbactam,one strain was resistant to cefazolin,and one strain was resistant to cefoxitin.Nine Stx2k-STEC strains were found to carry the beta-lactam resistance gene blaEC-18.Antimicrobial sensitivity tests revealed that the nine Stx2k-STEC strains were sensitive to all 15 tested antibiotics.Moreover,phylogenetic analysis indicated that the 9 Stx2k-STEC strains were remarkably similar but showed high genetic diversity with respect to that of the Stx2k-STEC strains isolated from other regions in China.Goatsare an important animal reservoir for STEC in theChengkou district of Chongqing,and novel sequence type Stx2k-STEC strains distinct from those found in other regions of China were identified in this region.

Objective:To explore the effect of preoperative visits based on lean management theory in the preoperative psychological state of patients undergoing cardiopulmonary bypass surgery.Methods:According to the coin toss method,72 patients undergoing cardiopulmonary bypass surgery admitted to the Cardiothoracic Surgery Department of Chenzhou First People's Hospital from May 2024 to August 2024 were randomly divided into control group and observation group,with 36 cases in each group.The control group was given routine preoperative visits,and the observation group was given preoperative visits based on lean management theory on the basis of the control group.The psychological state,information demand level,vital signs and satisfaction of the patients were compared between the two groups 1 day before operation and when entering the room.Results:After intervention,the scores of State Anxiety Scale(S-AI)and Amsterdam Preoperative Anxiety and Information Scale(APAIS)were decreased in both groups,and the observation group were significantly lower than control group(P＜0.05).The vital signs(heart rate,systolic blood pressure and diastolic blood pressure)in observation group were lower than control group(P＜0.05).After intervention,the satisfaction of patients in observation group was significantly increased(P＜0.05).Conclusion:The implementation of preoperative visit based on lean management theory can help improve the preoperative psychological state of patients undergoing cardiopulmonary bypass surgery,eliminate anxiety,provide patients with more targeted surgical information support for patients,stabilize patients 'vital signs,and improve patients' satisfaction.

Objective:To investigate the predictive value of endothelial activation and stress index(EASIX)for the prognosis of patients with mantle cell lymphoma(MCL).Methods:A retrospective analysis was conducted to assess prognosis and compare the clinical features of patients diagnosed with MCL who were admitted to the Affiliated Hospital of Xuzhou Medical University from January 2010 to June 2023,had therapeutic indications and received standard treatment.Results:A total of 66 patients were included and divided into high EASIX group and low EASIX group,according to a cutoff value of 0.97 determined by the receiver operating characteristic(ROC)curve.Multivariate Cox regression analysis showed that prealbumin＜0.2 g/L,high EASIX,and ECOG PS score ≥2 were independent risk factors influencing overall survival(OS)in MCL patients.The median OS of patients in the high and low EASIX group was 13.0 and 37.5 months,and the median progression-free survival was 8.8 and 26.0 months,respectively.The proportions of patients with ECOG PS score ≥2 and prealbumin＜0.2 g/L at onset significantly increased in the high EASIX group compared to those in the low EASIX group.Conclusion:At the time of initial diagnosis,EASIX can serve as an independent prognostic indicator impacting OS in patients with MCL.Furthermore,patients in the high EASIX group experience a poorer prognosis and shorter survival duration compared with those in the low EASIX group.
