Objective:To explore the correlations between the cerebral infarction area and cytokines and immune status in patients with acute ischemic stroke,and to provide the theoretical basis for immunotherapy of the patients with different degrees of cerebral infarction.Methods:Sixty-seven patients with acute ischemic stroke within 72 h of the onset were randomly selected according to the inclusion and exclusion criteria,and were divided into large-area cerebral infarction group(n=34)and non-large-area cerebral infarction group(n=33)on the basis of the biggest infarction area in the sequences of magnetic resonance diffusion-weighted imaging(CDWI).Clinical baseline characteristics such as gender,age,and medical history were collected from the patients in two groups,the serum levels of interleukin(IL)-2,IL-6,IL-10,and IL-17A,tumor necrosis factor-α(TNF-α),and interferon-γ(IFN-γ)were measured using flow cytometry;the absolute values of lymphocytes(LYM#),lymphocyte percentages(LYM％),and neutrophil/lymphocy ratios(NLR)in peripheral blood of the patients caiculated,and the ratios of IFN-γ/IL-4,TNF-α/IL-4,and TNF-α/IL-10 rations were also calculated.The values of National Institutes of Health Stroke Scale(NIHSS)scores of the patients were evaluatd on the basis of the assessment of clinical neurological signs.The correlations of the cerebral infarction area and NIHSS score,cytokines and immune status groups of the patients in two were tested by rank correlation analysis.Results:Compared with non-large-area cerebral infarction group,the serum levels of IL-2,IL-6,IL-10,IL-17A,TNF-α,and IFN-γ as well as the NLR in the peripheral blood of the patients in large-area cerebral infarction group were significantly increased(P＜0.01),while the LYM#,LYM％and TNF-α/IL-4 were significantly decreased(P＜0.01).There was a positive correlation between cerebral infarction area and NIHSS score in the patients in large-area cerebral infarction group(rs=0.521,P＜0.05),and there was a significantly positive correlation between cerebral infarct area and NIHSS score in the patients in non-large-area cerebral infarction group(rs=0.721,P＜0.001).The NIHSS scores were positively correlated with serum IL-6(rs=0.306,P=0.005),IL-4(rs=0.252,P＜0.001),IL-2(rs=0.109,P=0.025),IL-17A(rs=0.405,P＜0.001),and IFN-γ(rs=0.146,P＜0.001)levels in two groups;no correlations were found between NIHSS scores and TNF-α(rs=0.039,P=0.726)and IL-10(rs=0.121,P=0.192)levels.NIHSS scores of the patients in two groups had negative correlatious with the serum level of LYM#(rs=-0.026,P=0.036)and LYM％(rs=-0.008,P=0.002),and had positive correlated with NLR(rs=0.315,P=0.009).Conclusion:The infarction area of the patients with actue cerebral infarction is correlated with the NIHSS score,the inflammatory response,the degree of adaptive immune injury,and the immune status.The have positive correlation with cytokines and immune markers and the overall size of the infarction area.Compared with the patients with non-large-acea cerebral infarction,the immunosuppression of the patients with large-area infarcted areas is more likely to occure.

Standardized clinical trial reporting is crucial for ensuring the scientific validity,reproducibility,and clinical translational value of reported results.The Consolidated Standards of Reporting Trials(CONSORT)statement,an internationally recognized guideline for randomized controlled trials(RCTs),has become an important reference standard for writing research papers in medicine since the 2010 version of CONSORT was published.With advancements in scientific research methodologies and the emergence of new forms of clinical trials,the CONSORT working group released an updated version in April 2025,published in journals such as The BMJ.Herein,we provide a systematic interpretation of the core revisions of CONSORT 2025,as well as a comparison with CONSORT 2010 to highlight the key differences.By providing practical,example-based recommendations,we aim to help domestic researchers apply the new guidelines efficiently,thereby improving the quality of clinical trial reports authored by domestic researchers.

A high-quality clinical trial protocol is the cornerstone for ensuring the scientific integrity and ethical compliance of a study.The Standard Protocol Items:Recommendations for Interventional Trials(SPIRIT)has become the international benchmark for developing clinical trial protocols since its release in 2013.To adapt to the developing trends of open science and patient-centered principles,the SPIRIT group completed a comprehensive update in 2025.While retaining its core structure,this updated guideline introduces a new open science module and incorporates several new elements,including patient and public involvement,trial monitoring,and data sharing,alongside substantial revisions of five pre-existing items.In this article,we critically examine the core revisions in SPIRIT 2025 and,through analysis of representative case studies,illustrate the practical application of the new reporting guideline in drafting trial protocols.Our goal is to to provide Chinese researchers with a valuable reference for understanding and implementing this new reporting guideline,thereby enhancing the quality and rigor of clinical trial protocols developed in the country.

Objective To investigate the factors associated with atrial fibrillation(AF)in patients with Type 2 Diabetes Mellitus(T2DM).Methods Through a case-control study,We selected 688 patients with T2DM who were hospitalized at the First Affiliated Hospital of Kunming Medical University from January 2015 to November 2021.Based on the AF diagnostic criteria,all the patients were divided into a case group(AF group)of 368 cases and a control group(non-AF group)of 320 cases.All patients'clinical data were collected and used Stata 15.1 st-atistical software were used for analyze the relevant influencing factors of AF in patients with T2DM.Results Age,duration of DM,glycated hemoglobin level,body mass index,left atrial diameter,creatinine,C2HEST score,and heart failure might be risk factors for AF in T2DM patients(P＜0.05);among them,age,glycated hemoglobin level,left atrial diameter,C2HEST score might be independent risk factors for AF in T2DM patients;the use of sodium-glucose co-transporter 2 inhibitors(Sodium/Glucose Co-transporter 2 Inhibitor,SGLT2i)and β-blockers(P＜0.05)might be its protective factors.Conclusion Old age,high HbA1c level,increased left atrial diameter,and high C2HEST score maight be independent risk factors for atrial fibrillation in T2DM patients.The use of SGLT2i and β-blockers in T2DM patients may have a protective effect on the occurrence of atrial fibrillation.

Overexpression of exogenous lineage-determining factors succeeds in directly reprogramming fibroblasts to various cell types. Several studies have reported reprogramming of fibroblasts into induced cardiac progenitor cells (iCPCs). CRISPR/Cas9-mediated gene activation is a potential approach for cellular reprogramming due to its high precision and multiplexing capacity. Here we show lineage reprogramming to iCPCs through a dead Cas9 (dCas9)-based transcription activation system. Targeted and robust activation of endogenous cardiac factors, including GATA4, HAND2, MEF2C and TBX5 (G, H, M and T; GHMT), can reprogram human fibroblasts toward iCPCs. The iCPCs show potentials to differentiate into cardiomyocytes, smooth muscle cells and endothelial cells . Addition of MEIS1 to GHMT induces cell cycle arrest in G2/M and facilitates cardiac reprogramming. Lineage reprogramming of human fibroblasts into iCPCs provides a promising cellular resource for disease modeling, drug discovery and individualized cardiac cell therapy.

Objective: To evaluate clinical outcomes of autologous (auto-HSCT) and allogeneic hematopoietic stem cell transplantation (allo-HSCT) for angioimmunoblastic T-cell lymphoma (AITL) . Methods: From June 2007 to June 2017, clinical data of AITL patients who underwent HSCT in eight hospitals were assessed retrospectively. Results: Of 19 patients, 13 male and 6 female with a median age of 50 (32-60) years old, 12 auto-HSCT and 7 allo-HSCT recipients were enrolled in this study, all donors were HLA-identical siblings. Two of allo-HSCT recipients were relapsed auto-HSCT ones. There were 5 patients (5/12) in complete response (CR) status and 7 (7/12) in partial remission (PR) status before transplantation in auto-HSCT group, and 2 (2/7) in PR status and 3 (3/7) in progression disease (PD) status before transplantation in allo-HSCT group. The median follow-up for the surviving patients was 46.5 months (range, 1-100 months) for the whole series, two patients lost in auto-HSCT group. Three patients developed acute graft-versus-host disease (aGVHD) and 5 chronic graft-versus-host disease (cGVHD) after allo-HSCT. Three patients died of primary disease and 1bleeding in auto-HSCT group. One patient died of primary disease and 2 transplantation-related mortality in allo-HSCT group. The 3-year cumulative overall survival (OS) were 56% (95%CI 32%-100%) and 57% (95%CI 30%-100%) for auto-HSCT and allo-HSCT, respectively (P=0.979) . The 3-year cumulative progression-free survival (PFS) were 34% (95%CI 14%-85%) and 57% (95%CI 30%-100%) for auto-HSCT and allo-HSCT, respectively (P=0.451) . Conclusion Both auto-HSCT and allo-HSCT were optimal choices for AITL. In clinical practice, which HSCT was better for AITL patients should be based on comprehensive factors including sensitivity to chemotherapy, risk stratification and disease status at transplantation.

Objective To investigate the correlation of the 24?hour ambulatory systolic blood pressure (SBP) and carotid intima?media thickness(CIMT) in the elderly. Methods A total of 2 464 who were more than or equal to 60 years old participants were selected with random sampling in accordance with the inclusion criteria from the retired workers in Tangshan Kailuan Company. Dynamic blood pressure monitoring, neck vascular ultrasound and other examination were performed for the participants. . Multivariable linear regression analysis was used to analyze correlation between the SBP of 24?hour, daytime and nightime with CIMT, respectively. Results ( 1) The observation population was divided into three groups according to the tertiles of SBP of 24?hour, daytime and nightime, respectively. With the levels of different SBPs inceasing, CIMT values thickened markedly ( P<0. 01 ) . ( 2 ) Multivariable linear regression analysis showed that after adjusting for confounding factors,the SBP of 24?hour,daytime and nightime associated with CIMT positively and linearly(P<0. 05),and regression coefficient(95%CI) were 0. 022(0. 009-0. 035), 0. 021(0. 008-0. 035), 0. 019 ( 0. 006-0. 032) respectively. In addition,clinic SBP step into the multivariable linear regression,and regression coefficient ( 95%CI ) were 0. 016 ( 0. 003-0. 029 ) , 0. 016 ( 0. 003-0. 030 ) , 0. 019 ( 0. 007-0. 032 ) , respectively. Conclusion The effect of increased 24?hour ambulatory SBP on CIMT was greater than the clinic SBP. Active monitoring of 24 h ambulatory blood pressure and maintaining a low level of blood pressure is essential for preventing and delaying atherosclerosis.
