To explore the role of the "Clinical Practice Guidelines" column and others in the Medical Joumnal of Peking Union Medical College Hospital (Med J PUMCH) in promoting diseiplinary development.

To introduce and analyze guideline terminology related to clinical question formulation, evidence retrieval and appraisal, and recommendation development.

To develop a guideline terminology system and promote its standardization, thereby enhancing medical staff's accurate understanding and correct application of guidelines.

Objective:This study aims to evaluate the subcortical structural alteration patterns associated with five distinct neuropsychiatric symptoms (NPS) associated with Parkinson′s disease and provide macroscopic brain structural evidence to further explore their underlying pathophysiological mechanism.Methods:Clinical data and 3D-T 1 weighted images from 505 patients with Parkinson′s disease and 167 age-and sex-matched healthy controls were obtained from the Parkinson′s Progression Markers Initiative database (July 2010-August 2022). The subcortical nucleus volumes of the overall NPS patient group, as well as subgroups of patients with specific NPS subtypes (depression, anxiety, apathy, impulsive-compulsive behaviors (ICBs), and hallucinations), were measured and compared to those of healthy controls through mixed-effects models. Spatial similarity analysis and hierarchical clustering analysis of subcortical volume alteration patterns were employed to investigate the commonalities and specificities of subcortical damage in NPS. Results:NPS patients exhibited widespread subcortical atrophy, primarily concentrated in the bilateral putamen, bilateral hippocampus, and left amygdala (Cohen′s d=-0.38--0.12, FDR P<0.05). Subgroup analysis revealed that anxiety and depression were associated with gray matter atrophy in the bilateral putamen and amygdala (Cohen′s d=-0.73--0.32, FDR P<0.05), while apathy, hallucinations, and ICBs were linked to atrophy in the bilateral putamen, bilateral amygdala, and bilateral hippocampus (Cohen′s d=-0.61--0.11, FDR P<0.05,Cohen′s d=-0.43--0.36, P<0.05). Similarity and clustering analyses demonstrated high spatial correlation between anxiety and depression ( r=0.83, P<0.01), forming one cluster, whereas apathy, hallucinations, and ICBs formed another distinct cluster. Conclusion:NPS in Parkinson′s disease exhibit both commonalities and specificities. Apathy, hallucinations, and ICBs are associated with more severe subcortical damage patterns. These findings may provide new insights into the pathophysiology and progression of Parkinson′s disease.

Objective:To investigate the awareness of clinical practice guidelines (referred to as "guidelines") and experts consensus (referred to as "consensus") among otorhinolaryngology head and neck surgery medical staff, and to analyze the effectiveness of the ninth guideline methodology workshop.Methods:Self-designed survey questionnaires were used to conduct two surveys among otorhinolaryngology head and neck surgery medical staff who participated in the ninth guideline methodology workshop held in Chengdu from Jannuary 10 to 11, 2025, both before and after the training, to assess their awareness and knowledge of guideline and consensus development methodology. The effectiveness of the training was evaluated using the paired chi-square test.Results:A total of 77 peoples (95.06%), who participated in the ninth guideline methodology workshop, completed the survey questionnaires both before and after the training. One-third of the respondents reported a relatively good to very good understanding of guideline and consensus development. The overall methodology of the guidelines and consensus they had participated in developing still showed room for improvement. After the methodology training, the score rate for each test question significantly increased compared to before the training ( P<0.05), and the distribution trend of the total scores changed markedly (Before the training, 71 people scored less than 60 points, 4 people scored 60 points, and 2 people scored 70 points. After the training, only 1 person scored less than 60 points, 1 person scored 60 points, and 75 people scored between 70 and 100 points, of which 21 people scored 100 points). Conclusion:The awareness of guideline and consensus development methodology among otorhinolaryngology head and neck surgery medical staff still has room for improvement. The guideline methodology workshop can enhance participants′ mastery of guideline and consensus development methodology.

Objective To sort,summarize,and introduce key terms related to guideline reporting,evaluation,dissemination,implementation,and updating.Methods We systematically searched guideline de-velopment manuals and methodological literature from database inception to October 25,2024.Terms related to guideline reporting,updating,evaluation,and implementation were extracted,standardized,and finalized through a structured consensus process.Results A total of 13 guideline manuals and 32 methodological articles were included,yielding 14 core terms with standardized definitions.Conclusions This article introduces key terms such as reporting standards,external review,and research gaps across guideline development phases to promote concept application and deepen readers'understanding of guideline development.

The research advancements of sodium-glucose cotransporter-2 inhibitors (SGLT2i) in chronic kidney disease (CKD) were a central theme at the 2024 American Society of Nephrology (ASN) Kidney Week. Clinical studies reaffirmed the cardio-renal benefits of SGLT2i in CKD patients, including those with advanced-stage disease and elderly populations. Notably, these benefits persisted for up to 12 months after treatment discontinuation. Furthermore, CKD management has evolved from a traditional "three-pillar" approach to a "four-pillar" strategy, with combination therapies demonstrating significant synergistic potential for cardio-renal protection. Mechanistic studies revealed novel pathways through which SGLT2i exert renoprotective effects, including promoting renal regeneration, modulating epigenetic modifications, regulating immune cell activity, and restoring proximal tubule metabolic homeostasis. Further research is warranted to optimize therapeutic outcomes and maximize clinical benefits for patients.
