目的 验证尿沉渣评分（USS）对肾前性急性肾损伤（AKI）与急性肾小管坏死（ATN）的鉴别价值，评估USS与AKI严重程度及预后的相关性，为优化AKI分层管理提供依据。方法 回顾性分析2021年3月至2022年2月在郑州市中医院治疗的120 AKI患者，根据肾组织活检及改良FENa-UA诊断标准分为肾前性AKI组（n=68）与ATN组（n=52），于入院日检测USS、血清胱抑素C（Cys-C）及尿中性粒细胞明胶酶相关脂质运载蛋白（NGAL），分析USS诊断效能。结果 ATN组USS高于肾前性组（P＜0.001），且评分随AKI分期升高而增加（P＜0.001）。USS诊断肾前性AKI的ROC曲线下面积（AUC）为0.892，联合Cys-C与NGAL后AUC提升至0.941，灵敏度与特异度分别达90.12%和88.51%。结论 USS通过量化肾小管结构性损伤，可早期鉴别肾前性AKI与ATN，其与Cys-C、NGAL的联合应用提高诊断准确性，且对AKI预后具有重要价值，为临床分层管理提供客观依据。

       Objective To validate the discriminative value of urinary sediment score（USS）in differentiating prerenal acute kidney injury（AKI）from acute tubular necrosis（ATN），and to evaluate the correlation between USS and AKI severity/prognosis，providing evidence for optimizing stratified AKI management．Methods A retrospective analysis was conducted on 120 AKI patients treated at Zhengzhou Traditional Chinese Medicine Hospital from March 2021 to February 2022．According to renal tissue biopsy and modified FENa-UA diagnostic criteria，patients were divided into a prerenal AKI group（n=68）and an ATN group（n=52）．On the day of admission，USS，serum cystatin C（Cys-C），and urinary neutrophil gelatinase-associated lipocalin（NGAL）were measured to analyze the diagnostic performance of USS．Results USS was significantly higher in ATN group than prerenal group（P＜0.001），and increased with advancing AKI stages（P＜0.001）．The area under the ROC curve（AUC）of USS for diagnosing prerenal AKI was 0.892，which improved to 0.941 when combined with Cys-C and NGAL，yielding sensitivity and specificity of 90.12% and 88.51%，respectively．Conclusions USS quantifies structural damage to the renal tubules，allowing for early differentiation between prerenal AKI and ATN．Its combined use with Cys-C and NGAL improves diagnostic accuracy and is of significant value in predicting AKI prognosis，providing an objective basis for clinical stratified management．

目的 通过观察隔姜灸神厥穴并同时口服黄芪汤治疗脓毒症急性肾损伤患者的效果分析,初步探讨该方法能否改善患者的APACHEⅡ评分,入住重症监护病房的时间有没有缩短,14天内死亡率有否差异。方法 以2014年1月—2015年8月于我院确诊的脓毒症急性肾损伤患者为研究对象,观察常规治疗(对照组)及常规治疗基础上给予隔姜灸神厥穴同时口服黄芪汤治疗(治疗组)对脓毒症急性肾损伤患者危重情况的影响。结果 治疗组患者的危重指标(APACHEⅡ评分)明显改善,患者治疗5天后组间比较差异有统计学意义(P<0.05);两组患者入住重症监护病房的时间比较,患者治疗第四周χ²=4.5241,P=0.0334,差异有统计学意义(P<0.05);14天死亡率差异无统计学意义(P>0.05)。结论 隔姜灸神厥穴同时口服黄芪汤治疗能有效改善脓毒症急性肾损伤患者的APACHEⅡ评分,入住重症监护病房的时间减少。
