Objective:To observe the clinical study of He Ne laser combine with compound betamethasone local injection in the treatment of alopecia areata(alopecia areata,AA).Methods:This study was a prospective randomized controlled trial,used random number table,100 AA patients who were admitted to our hospital from March 2020 to July 2024 were divided into control group(treated with compound betamethasone local injection,n=50)and study group(treated with He Ne laser combined with compound betamethasone local injection,n=50).The clinical efficacy,conventional scale scores[Skin dermatology life quality index(DLQI),severity of alopecia tool(SALT)],serum inflammatory factors[leukotriene C4,c-reactive protein(CRP),interleukin-10(IL-10),soluble interleukin-2 receptor(sIL-2R)],immune function,and adverse reactions between two groups were compared.Results:The total clinical effective rate,IL-10,CD3+,CD4+,CD4+/CD8+in the study group were higher than those in the control group after treatment,while the DLQI score,SALT score,leukotriene C4,CRP,SIL-2R,and CD8+were lower than those in the control group(P＜0.05).There was no significant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion:He Ne laser combined with compound betamethasone local injection in the treatment of AA patients,can improve clinical efficacy,and symptoms,which may be related to the regulation of inflammatory factors and immune function,which is safe and reliable.

Aim To investigate the effects of dimethyl-arginine dimethylamino hydrolase 1(DDAH1)on high glucose-induced mitochondrial dysfunction and mitoph-agy in vascular endothelial cells.Methods JC-1 stai-ning was used to detect mitochondrial membrane poten-tial.DCFH-DA fluorescent probe was employed to measure reactive oxygen species(ROS)levels.Ho-echst staining was used to assess cell apoptosis.Real-time PCR was conducted to detect DDAH1 mRNA lev-els.Western blot was performed to analyze the expres-sion of DDAH1,LC3-Ⅰ and LC3-Ⅱ proteins.Mitochon-drial probe Mitotracker and autophagosome marker pro-tein LC3 were used in cell immunofluorescence co-lo-calization to assess mitochondrial autophagy,and high-performance liquid chromatography was utilized to measure the levels of asymmetric dimethylarginine(ADMA)in cell supernatant.Results High glucose treatment for 48 h significantly reduced mitochondrial membrane potential,increased ROS production,and promoted apoptosis in human umbilical vein endothelial cells(HUVECs).High glucose downregulated the ex-pression of LC3-Ⅱ/LC3-Ⅰ proteins,reduced the co-lo-calization of Mitotracker and LC3,and inhibited mito-chondrial autophagy.Autophagy inhibitors 3-MA or CQ exacerbated high glucose-induced mitochondrial dam-age and apoptosis in HUVECs,while autophagy activa-tor RAPA alleviated these effects.High glucose signifi-cantly downregulated DDAH1 protein expression in HUVECs and increased ADMA levels in cell superna-tant.DDAH1 siRNA inhibited mitochondrial autoph-agy,reduced mitochondrial membrane potential,and promoted apoptosis,whereas DDAH1 overexpression enhanced mitochondrial autophagy and alleviated high glucose-induced apoptosis in HUVECs.Conclusion High glucose-induced endothelial mitochondrial dys-function is associated with the suppression of DDAH1 expression,the increase of ADMA levels,and thereduc-tion of mitochondrial autophagy.

Objective To establish an expert consensus on the management of mini-midline catheters(hereinafter referred to as the'consensus')to guide nurses in standardizing the insertion and maintenance of mini-midline catheters.Methods Evidence was systematically retrieved,scientifically evaluated,and synthesized using evidence-based methods to draft the initial version of the consensus.From December 2023 to July 2024,totally 2 rounds of expert correspondence and 2 rounds of expert panel discussions were conducted to revise the content,resulting in the final version.Results There were 17 experts from tertiary A general hospitals in Beijing,Shanghai,Hunan,Hubei,Sichuan,Jiangsu,Hainan,Guangxi Zhuang Autonomous Region,and Shandong participating in the consultation,with a 100％response rate.In the 2 rounds of expert correspondence,the authority coefficients were 0.947 and 0.962,respectively.The mean importance scores of all items exceeded 4.00 points.The coefficients of variation(CV)were 0-0.32(first round)and 0-0.15(second round).Kendall's concordance coefficients were 0.097 and 0.101(both P＜0.001).The consensus covers 11 sections,including definition,indications,contraindications,qualification training,pre-insertion preparation,catheter insertion,catheter use,catheter maintenance,catheter removal,prevention and management of common complications,and health education.Conclusion The Consensus demonstrates scientific rigor and comprehensively addresses key procedures before,during,and after the insertion of mini-midline catheters,providing actionable guidance for nurses in catheter insertion and maintenance.

Schizophrenia(SZ)is a psychiatric disorder characterized by abnormalities in brain structures and function.Diffusion MRI,such as diffusion tensor imaging(DTI),diffusion kurtosis imaging(DKI),diffusion spectrum imaging(DSI),neurite orientation dispersion and density imaging(NODDI),as well as high angular resolution diffusion imaging(HARDI)can help reveal microstructural abnormalities of white matter in SZ patients.The research progresses of diffusion MRI for SZ were reviewed in this article.

Non-suicidal self-injury(NSSI)refers to a mental disorder characterized by deliberate self-harm behaviors without suicidal intent.The pathogenesis of NSSI remains unclear,but may be related to abnormalities in reward circuitry,pain processing,emotion regulation,impulse control and hypothalamic-pituitary-adrenal axis.Task state functional MRI(fMRI)provides valuable insights into the intrinsic connections and neural circuits mechanisms underlying NSSI during various task states or behaviors.Research progresses of task state fMRI in pathogenesis of NSSI were reviewed in this article.

Sepsis is a systemic inflammatory response triggered by infection and often leads to acute kidney injury(AKI).The pathogenesis of sepsis-associated AKI is complex,involving multiple factors such as renal ischemia,inflammation and oxidative stress.In recent years,pyroptosis,a pro-inflammatory form of programmed cell death,has gradually attracted the attention of researchers.Pyroptosis is activated by inflammasomes(e.g.,the NOD-like receptor pyrin domain-related protein 3 inflammasome,NLRP3 inflammasome),accompanied by Gas-dermin D(GSDMD)-mediated formation of cell membrane pores and release of cellular contents,which leads to exacerbation of local and systemic inflammatory responses.The mechanism of pyroptosis in sepsis-associated AKI has not been fully elucidated,but AKI is directly involved in the process of renal functional impairment by indu-cing the death of renal tubular epithelial cells and exacerbating the local inflammatory response.Blockade of key molecules in the pyroptosis pathway,such as GSDMD or NLRP3 inflammasome,can significantly alleviate renal injury,suggesting that the pyroptosis pathway may be a potential therapeutic target for sepsis-associated AKI.This review summarizes the recent research progress on pyroptosis in sepsis-associated AKI,and discuss its cen-tral role in the pathogenesis,particularly focusing on the inflammasome and GSDMD pathways.Additionally,this paper analyzes the potential of focal death inhibition as a therapeutic strategy and proposes future research direc-tions with the expectation of providing references for the treatment of sepsis-related AKI.

Objective To investigate the therapeutic effect of folic acid combined with decitabine in diabetic retinop-athy(DR)mice with different methylenetetrahydrofolate reductase(MTHFR)genotypes.Methods The DR model mice were created by mating 20 MTHFR-/-mice with 20 wild-type C57 mice.A random number table method was employed to allocate 20 successfully modelled mice into the model group,DAC group,FA group,and FA+DAC group,with five mice assigned to each group.Five untreated MTHFR-/-and wild-type mice served as normal control.After constructing the DR model,the DAC group was injected intraperitoneally with 0.25 mg·kg-1 decitabine once every 5 days;the FA group was given 70 μg·kg-1 folic acid by tube feed once a day;the FA+DAC group was given 0.25 mg·kg-1 decitabine and 70μg·kg-1 folic acid at the same time;and the normal group was given an equal amount of physiological saline.All of the above groups were intervened for 30 days.OCT was employed for the measurement of retinal thickness,OCTA for retinal vascular density,histopathology(HE staining)for pathological changes in the mouse retina,real-time fluorescence quanti-tative PCR for mRNA expression,and Western blot analysis for protein expression levels.Results Compared with the wild-type model group,the degree of increase in retinal thickness and vascular density in the retinal layer was more pro-nounced in the MTHFR-/-mice model group(all P＜0.05).In wild-type mice,retinal thickness and retinal layer vessel den-sity were reduced in the DAC,FA and FA+DAC groups compared to the model group,with the FA+DAC group show-ing the greatest degree of reduction.The differences were all statistically significant(all P＜0.05);In MTHFR-/-mice,reti-nal thickness and vascular density in the retinal layer were reduced in the DAC group and the FA+DAC group compared to the model group(allP＜0.05).HE staining results showed an increased extent of retinal damage in the MTHFR-/-mice model group compared with the wild-type mice model group.Compared with the model group,the DAC group and the FA+DAC group had thinner retinas and more aligned ganglion cell layers in all types of mice,with the FA group having a worse effect and the FA+DAC group having a better treatment effect.The results of the polymerase chain reaction(PCR)revealed that the relative expression of the SAHH,MAT2A and DNMT1 proteins in the retinal tissues of the wildtype and MTHFR-/-mice model groups was elevated in comparison to the control group(all P＜0.05).Furthermore,the relative mR-NA expression of the DAC,FA and FA+DAC groups was reduced in comparison to the model group(all P＜0.05).In wild-type mice,the relative expression of MTHFR protein mRNA was decreased in the model group compared with the con-trol group,and increased in the DAC group,FA group,and FA+DAC group compared with the model group(all P＜0.05).Western blot results showed that the relative expression of DNMT1,MAT2A and SAHH proteins in the retinal tissues of the wild-type and MTHFR-/-mice model groups was higher than that of the control group(all P＜0.05),and the relative expression was lower in the DAC,FA,and FA+DAC groups compared with that in the model group(all P＜0.05).In wild-type mice,the relative expression of MTHFR protein in the retinal tissue of the model group was lower than that of the control group,and the relative expression of MTHFR protein in the FA group and the FA+DAC group was elevated com-pared with that of the model group(all P＜0.05).Conclusion The protective effect of folic acid combined with decit-abine on DR was superior to that of decitabine alone;treatment with folic acid in combination with decitabine may have yielded better efficacy in wild-type DR mice.

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.
