      Objective To construct a risk prediction model for stroke associated pneumonia in patients with initial cerebral hemorrhage（ICH）and validate the predictive performance of the model．Methods A retrospective analysis was conducted on the clinical data of 419 patients with ICH admitted to our hospital from January 2012 to December 2022．They were randomly divided into a development cohort（293 cases）and a validation cohort（126 cases）according to a 7∶3 ratio．The Logistic regression model was used to analyze the influencing factors of stroke related pneumonia in patients with ICH based on the development cohort data，and a risk prediction model was constructed．Based on the development cohort data and validation cohort data，the predictive performance of the model was analyzed using calibration curves，receiver operating characteristic（ROC）curve，and decision curve analysis．Results Among 419 patients，113 developed stroke associated pneumonia，with a rate of 26.97%．The National Institutes of Health Stroke Scale（NIHSS）score，swallowing difficulties，initial hematoma volume，neutrophil percentage to albumin ratio（NPAR），neutrophil count to lymphocyte count ratio（NLR），surgical treatment，endotracheal intubation，and indwelling gastric tube were all independent influencing factors for stroke associated pneumonia in patients with ICH（P＜0.05）．Based on the above influencing factors，a risk prediction model for stroke associated pneumonia in patients with ICH was constructed．The calibration curve showed that the predicted incidence of stroke associated pneumonia by the model in both the development and validation cohorts was close to the actual incidence．The ROC curve showed that the predicted area under the curve for this model in the development cohort and validation cohort was 0.906（95%CI：0.867-0.937）and 0.884（95%CI：0.815-0.934），respectively．The decision curve analysis showed that when the threshold probability of the development cohort was between 3%-80%，and the threshold probability of the validation cohort was between 2%-76%，the intervention using this model was more clinically valuable than all/no intervention．

Conclusions The risk prediction model for stroke associated pneumonia in patients with ICH based on NIHSS score，swallowing difficulties，initial hematoma volume，NPAR，NLR，surgical treatment，tracheal intubation，and indwelling gastric tube has good predictive performance and clinical application value．

Objective To compare the imaging times, image quality, and diagnostic performance of three-dimensional (3D) intermediate-weighted compressed sensing sensitivity encoding (IW-CS-SENSE) sequence with conventional 3D IW-SENSE sequence in knee MR imaging. Methods MR images of one hundred knees were obtained prospectively. The quantitative indices, qualitative scores, and grading accuracies between the two 3D sequences were compared. Results Imaging times of IW-CS-SENSE sequences were significantly reduced (122.0 ± 28.0 s vs. 221.0 ± 49.0 s, p < 0.001). The signal-to-noise ratios, contrast-to-noise ratios, and visualization scores of IW-CS-SENSE sequences were significantly lower than IW-SENSE sequences (p < 0.001), while scores of SENSE artefact for IW-CS-SENSE sequences were superior (5.00 ± 0.00 vs. 4.59 ± 0.62, p < 0.001). The accuracies in grading meniscal, ACL, and cartilage tears were comparable between the two sequences (p = 0.33, p = 0.58 and p = 0.15, respectively). Conclusion 3D IW-CS-SENSE sequences can reduce scanning time significantly and eliminate SENSE artefacts, while maintaining the same diagnostic performance as the 4-fold accelerated 3D IW-SENSE sequences.

目的：基于文献计量学梳理惯性测量技术在步态分析领域的研究演进与热点结构，并从护理评估与干预转化角度分析其应用空白。方法：检索 Web of Science 核心合集2005年1月1日至2025年4月5日相关英文文献，纳入1,079篇记录；采用 CiteSpace 6.3.R1、VOSviewer 1.6.20 分析年度发文、国家/地区合作、期刊分布、关键词共现与突现，并在 Python 3.10 中以 PPMI/TF-IDF 表征、SVD降维、UMAP-HDBSCAN聚类开展关键词和摘要语义分析。结果：2006—2024年发文量由1篇增至140篇，年复合增长率为31.6%，2024年达到峰值；最高频关键词为 gait（404次）、gait analysis（268次）、walking（252次）、balance（183次）和 inertial sensors（156次）。关键词与摘要语义聚类的二维轮廓系数分别为0.579和0.642，热点集中于帕金森病/冻结步态、跌倒风险、平衡稳定性、可穿戴传感器、机器学习和康复干预。含 nursing/care 等护理相关词项的记录为142篇，但“护理”尚未形成独立主题簇。结论：惯性测量步态分析已形成医工交叉的成熟热点，但护理主导的连续评估、风险预警和干预闭环仍不足。未来应将步速、步态变异性、稳定性、对称性等参数转化为可执行的护理评估指标，推动精准护理场景中的临床验证与流程整合。

Objective: To map the research evolution and hotspot structure of inertial-measurement-based gait analysis and to examine its translational gap in nursing assessment and intervention. Methods: A total of 1,079 English records published from January 1, 2005 to April 5, 2025 were retrieved from the Web of Science Core Collection. CiteSpace 6.3.R1 and VOSviewer 1.6.20 were used for annual output, collaboration, journal distribution, keyword co-occurrence and burst analyses. Keyword and abstract semantic clusters were further examined in Python 3.10 using PPMI/TF-IDF representation, SVD, UMAP and HDBSCAN. Results: Publications increased from 1 in 2006 to 140 in 2024, with a compound annual growth rate of 31.6%. The most frequent terms were gait, gait analysis, walking, balance and inertial sensors. The two-dimensional silhouette coefficients of keyword and abstract semantic clusters were 0.579 and 0.642, respectively. Major hotspots involved Parkinson disease/freezing of gait, fall risk, balance and stability, wearable sensors, machine learning and rehabilitation. Records containing nursing/care-related terms accounted for 142 publications, but nursing did not form an independent topic cluster. Conclusion: Inertial-measurement-based gait analysis has become a mature medical-engineering research field, while nurse-led continuous assessment, risk warning and intervention feedback loops remain underdeveloped. Translating gait speed, variability, stability and symmetry into actionable nursing indicators should be prioritized in future clinical validation.
