AIM: To investigate the influence of relevant inflammatory markers in peripheral blood on the progression of neovascular glaucoma(NVG)secondary to diabetic retinopathy(DR)patients.METHODS: Retrospective case-control study. Patients were categorized into two groups based on the presence or absence of NVG: those with proliferative diabetic retinopathy(PDR)alone(PDR group, n=148)and those with NVG secondary to PDR(NVG secondary to PDR group, n=142). Peripheral blood inflammatory markers were evaluated, including white blood cell-related indices, neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR), monocyte-to-lymphocyte ratio(MLR), and systemic immune-inflammation index(SII). The distinctions in peripheral blood inflammatory markers between the two groups of patients and their relationships with NVG secondary to PDR were analyzed.RESULTS:No statistically significant differences were observed in basic characteristics between the two groups, confirming their comparability. However, significant differences were found in eosinophil percentage and MLR between the PDR group and the NVG secondary to PDR group(all P<0.05), with both values being significantly higher in the NVG secondary to PDR group. Multivariate Logistic regression analysis revealed that the eosinophil percentage and the MLR were factors influencing the development of patients with NVG secondary to PDR.CONCLUSION: Eosinophil percentage and MLR may be associated with the progression of PDR to NVG, and could serve as potential predictive markers for NVG development in PDR patients.

ObjectiveTo establish a geographical origin identification model for Foeniculi Fructus from Haiyuan， providing a new technical reference for the protection of Haiyuan's geo-authentic medicinal materials and its designation as a national geographical indication agricultural product. MethodsSamples of Foeniculi Fructus were collected from eight producing areas， including Minqin （Gansu）， Bozhou （Anhui）， Qingdao （Shandong）， Dezhou （Shandong）， Urumqi （Xinjiang）， Nujiang （Yunnan）， Gutuo （Inner Mongolia）， and Haiyuan （Ningxia）. Gas chromatography-ion mobility spectrometry （GC-IMS） was used to detect the volatile organic compounds （VOCs） in samples from these geographic origins. VOCs were qualitatively analyzed through dual matching with the National Institute of Standards and Technology （NIST） mass spectral database and the IMS drift time database. Using the Reporter module and Gallery Plot visualization tools within the LAV analytical platform， VOC fingerprint profiles characterizing geographic origins were constructed. A non-targeted analytical strategy was adopted， and 97 VOCs detected via GC-IMS were subjected to principal component analysis （PCA） and partial least squares discriminant analysis （PLS-DA） based on their differential distribution patterns to construct an origin identification model for Foeniculi Fructus from Haiyuan region. Key discriminative markers were screened using variable importance in projection （VIP） values greater than 1. ResultsA total of 97 VOCs were identified， including alcohols， aldehydes， ketones， esters， organic acids， terpenoids， ethers， alkenes， and benzenes. The PLS-DA model， based on VOCs data obtained by GC-IMS， effectively distinguished Foeniculi Fructus in Haiyuan region from those of other origins. During cross-validation， the model achieved a prediction parameter （Q²） of 0.976 and a goodness-of-fit parameter （R²） of 0.936， with no overfitting observed in permutation testing. Twelve key flavor markers with VIP > 1 were identified as characteristic indicators of Haiyuan origin. ConclusionA stable and highly predictive origin identification model for Foeniculi Fructus from Haiyuan was successfully established using GC-IMS technology， PLS-DA， and VIP-based marker screening. This model provides a novel technical strategy for accurately distinguishing Foeniculi Fructus in Haiyuan region from other regional varieties and offers new technical support for its protection as a geo-authentic medicinal material and a nationally designated geographical indication agricultural product in China.

Aim To explore the effects of high glucose on KIAA0753 and CCSAP and the relationship between KIAA0753 and CCSAP and osteogenic differentiation and calcium signaling pathway under high glucose con-ditions.Methods Mouse embryonic osteoblast pre-cursor cells(MC3T3-E1)were induced by osteoblast medium with glucose concentrations of 5.5 and 25 mmol·L-1,and the protein expressions of KIAA0753 and CCSAP were detected by Western blot.The over-expressed plasmid was transfected into human embry-onic kidney cells(HEK-293T),and the interaction between KIAA0753 and CCSAP was detected by co-im-munoprecipitation.MC3T3-E1 cells were treated in the osteogenic medium with different glucose concentrations and induction times.Alkaline phosphatase(ALP)ac-tivity was detected with a kit.The expression of KI-AA0753,CCSAP,osteopontin,osteocalcin,and other proteins were assessed using Western blot.and then 5.5,25 mmol·L-1,and 25 mmol·L-1+OE-CCSAP three groups of MC3T3-E1 cells were set.The expression of KIAA0753,OCN,OPN protein,and ALP activity were detected successively.The diabetic mouse model dataset in Gene Expression Omnibus was used to screen differential genes for bioinformatics a-nalysis.MC3T3-E1 cells were set up in three groups,5.5,25 mmol·L-1,and 25 mmol·L-1+OE-KI-AA0753,respectively.The calcium/calmodulin-de-pendent protein kinase Ⅱ beta(CAMK2B)and phos-pholamban(PLN)were detected by Western blot.Re-sults Compared with the 5.5 mmol·L-1 group,25 mmol·L-1 inhibited the expression of KIAA0753 and CCSAP proteins in osteoblasts,and there was an inter-action between KIAA0753 and CCSAP.At the same time,25 mmol·L-1 also inhibited the expression of ALP,OPN,and OCN proteins in osteoblasts.Overex-pression of CCSAP at 25 mmol·L-1 up-regulated the expression of KIAA0753,OCN,OPN,and ALP.The differential genes of the diabetic mouse model were mainly concentrated in the aspects of"signal receptor and signal regulation".25 mmol·L-1 glucose inhibi-ted the expression of CAMK2B and PLN proteins in os-teoblasts,and overexpression of KIAA0753 at 25 mmol·L-1 upregulated the expression of CAMK2B and PLN proteins.Conclusions High glucose inhibits the expression of KIAA0753 and CCSAP protein,inhibits the osteogenic differentiation and calcium signaling in mouse embryonic osteoblast precursor cells,overex-pression of CCSAP saves the inhibitory effect of high glucose on osteogenic differentiation,and overexpres-sion of KIAA0753 reverses the inhibitory effect of high glucose on calcium signaling pathway.

Objective:To explore the activation pathway of CD4+CD28-T cells and their specific role in rheumatoid arthritis(RA).Methods:Peripheral blood mononuclear cells(PBMCs)were isolated from RA patients and healthy individuals.Flow cytome-try was used to detect the proportion and activation level of CD4+CD28-T cells,as well as the expressions of perforin and TNF-α,and to analyze the correlation between the proportion of CD4+CD28-T cells and age,C-reactive protein,anti-cyclic citrullinated peptide(CCP)antibodies,rheumatoid factors(RF)and erythrocyte sedimentation rate(ESR).The expression of Toll-like receptor(TLR)2 on CD4+CD28-T cells was detected by flow cytometry.Purified RA CD4+T cells were stimulated with anti-CD3 antibody and TLR2 agonist alone or in combination,and the activation level and cytokine secretion of CD4+CD28-T cells were detected by flow cytometry.Results:The proportion of CD4+CD28-T cells in RA patients was higher than that in healthy individuals(P<0.05),and was positively correlated with rheumatoid factors and erythrocyte sedimentation rate(r=0.554 1,P<0.01;r=0.363 4,P<0.01).Compared with CD4+CD28+T cells,CD25 expression was downregulate(P<0.01),but CD40L and TLR2 expressions were upregulated(P<0.01;P<0.000 1)in CD4+CD28-T cells from RA patients,and they secreted more perforin and TNF-α(P<0.001;P<0.001).After TLR2 ago-nist stimulation,there was no significant change in CD40L and CD25 expression,as well as perforin and TNF-α secretion in CD4+CD28-T cells from RA patients.Conclusion:The proportion of CD4+CD28-T cells is increased in RA patients,and they secrete a large amount of perforin and TNF-α,which may be involved in the inflammatory state and joint damage of RA,but TLR2 cannot re-place CD28 in activating CD4+CD28-T cells.

Objective:To explore the effect of horizontal Baduanjin guided by interactive standard reaching theory(ISRT)on cardiac function and quality of life in patients with chronic heart failure(CHF).Methods:This random-ized controlled study enrolled 114 patients diagnosed with CHF in Bozhou People's Hospital between September 2024 and February 2025.Patients were randomly divided into control group(n=57,routine nursing care)and interven-tion group(n=57,horizontal Baduanjin under the guidance of interactive standard theory).Both groups were con-tinuously treated for 3 months.Cardiac function indexes,N-terminal pro-brain natriuretic peptide(NT-proB-NP),self-care ability,quality of life and incidence of major adverse cardiovascular events(MACE)were com-pared between the two groups.Results:Compared to patients in the control group,those in the intervention had significant higher left ventricular ejection fraction(LVEF)[(56.34±0.86)％vs.(46.69±0.91)％],6min walking distance(6MWD)[(477.16±6.62)m vs.(451.39±4.17)m]and the proportion of New York Heart Association(NYHA)class Ⅱ(70.18％vs.35.09％),and significant lower NT-proBNP[(237.76±6.41)pg/ml vs.(377.46±6.85)pg/ml],scores of the European heart failure self-care behavior scale 9(EHFSCB-9)[(12.61±1.81)points vs.(25.51±1.71)points],the physical domain[(3.96±0.91)points vs.(11.05±0.79)points],emotional domain[(4.00±0.85)points vs.(11.95±0.81)points]and other domain[(4.05±0.83)points vs.(13.47±1.15)points]of MLHFQ(P＜0.001 all).Compared to those in the control group,patients in intervention group had significant lower incidence of MACE(7.02％vs.22.81％,P=0.035).Conclusion:Under the guidance of the interactive standard theory,the horizontal Baduanjin exercise may enhance the cardiac function,improve self-care ability and quality of life in patients with chronic heart failure.

Objective:To analyze the predictive value of dynamic changes of myocardial enzymes for late microvascu-lar obstruction(MVO)in patients with acute myocardial infarction(AMI)after percutaneous coronary intervention(PCI).Methods:The clinical data of 123 AMI patients who underwent PCI in Peking University Third Hospital Qinhuangdao Hospital between June 2020 and December 2022 were retrospectively analyzed.Patients were divided into late MVO group(n=52)and non-late MVO group(n=71)according to the occurrence of late MVO 4-7 d after PCI.The myocardial enzyme spectrum indexes of the two groups before and 1 d after operation were collect-ed.Myocardial enzyme spectrum indexes were compared between the two groups.Multivariate Logistic regression a-nalysis was used to analyze the related factors affecting late MVO in AMI patients after PCI.The receiver operating characteristic(ROC)curve was drawn to analyze the predictive efficacy of myocardial enzyme changes for late MVO in AMI patients after PCI.Results:At 1 d after operation,compared to patients in non-late MVO group,those in the late MVO group had significant higher lactate dehydrogenase(LDH)[(332.12±34.28)IU/L vs.(308.66±30.9)IU/L],aspartate aminotransferase(AST)[(64.89±6.11)IU/L vs.(58.84±4.96)IU/L],crea-tine kinase(CK)[(240.60±32.51)IU/L vs.(214.69±30.27)IU/L],creatine kinase isoenzyme(CK-MB)[(35.01±4.73)IU/L vs.(30.27±4.60)IU/L]and α-hydroxybutyrate dehydrogenase(α-HBDH)[(55.24±4.20)U/L vs.(50.64±3.87)U/L](P＜0.001 all).Multivariate Logistic regression analysis showed that LDH(OR 1.034,95％CI 1.013～1.054),AST(OR 1.173,95％CI 1.052～1.308),CK(OR 1.038,95％CI 1.014～1.062),CK-MB(OR 1.310,95％CI 1.139～1.508)and α-HBDH(OR 1.379,95％CI 1.167～1.630)at 1 d af-ter operation were independent risk factors of late MVO in AMI patients after PCI(P＜0.01 all).ROC analysis showed that the area under the curve(AUC)of LDH,AST,CK,CK-MB,α-HBDH alone and combined detec-tion in predicting late MVO in AMI patients after PCI were 0.705(95％CI 0.609～0.801),0.793(95％CI 0.707～0.879),0.712(95％CI 0.621～0.804),0.767(95％CI 0.683～0.851),0.798(95％CI 0.718～0.878)and 0.950(95％CI 0.914～0.986)respectively.The AUC of combined prediction was better than those of single predic-tions(Z=2.807～4.882,P＜0.05 or＜0.01).Conclusion:Changes in myocardial enzyme spectrum may increase the risk of late MVO in AMI patients after PCI and combined detection have good predictive efficacy for it.
