       目的 调查老年脆性骨折患者术前衰弱现况,并分析影响因素。方法 采用便利抽样法, 2024年11月—2025年3月, 选取于广州市某三甲医院骨科住院的207例老年脆性骨折患者, 使用一般资料调查表、简易衰弱评估量表、简版流调中心抑郁量表、广泛性焦虑量表和营养风险筛查量表2002开展问卷调查。采用有序分类Logistic回归, 分析老年脆性骨折患者术前衰弱的影响因素。结果 207例老年脆性骨折患者的术前衰弱前期占48.3%, 衰弱发生率为23.2%。有序分类Logistic 回归分析结果显示年龄（OR=1.131）、睡眠差（OR=2.557）、合并3种及以上慢性病（OR=3.990）、抑郁（OR=3.296）、营养不良风险（OR=4.005）为老年脆性骨折患者术前衰弱的危险因素,BMI正常（OR=0.206）是保护因素（均P<0.05）。结论 老年脆性骨折患者年龄, 睡眠情况, 多种共病,抑郁, 存在营养不良风险及BMI影响其术前衰弱水平, 重视衰弱的筛查及早期干预, 提升患者治疗效果和生活质量。

       Objective To explore the preoperative frailty status and influencing factors in elderly patients with osteoporotic fractures．Methods Using convenience sampling, 207 elderly patients with osteoporotic fractures admitted to the orthopedic department of a tertiary hospital in Guangzhou from November 2024 to March 2025 were selected．Data were collected using a general information questionnaire, the Frail Scale, the 10-item Center for Epidemiologic Studies Depression Scale（CES-D-10）, the Generalized Anxiety Disorder Scale（GAD-7）, and the Nutritional Risk Screening 2002（NRS-2002）．Logistic regression was used to analyze factors influencing preoperative frailty．Results Among 207 elderly patients with osteoporotic fractures, the incidence of early stages of frailty was 48.3%, and the incidence of frailty was 23.2%．Logistic regression analysis revealed the following risk factors for preoperative frailty：age（OR=1.131）, poor sleep quality（OR=2.557）, multiple chronic comorbidities（OR=3.990）, depression（OR=3.296）, nutritional risk（OR=4.005）．Normal body mass index（OR=0.206）was a protective factor．Conclusions Advanced age,poor sleep quality, multiple chronic comorbidities, depression, nutritional risk and body mass index are associated with frailty in elderly osteoporotic fracture patients．Health care providers should pay attention to frailty screening and early intervention, which can reverse or delay the progression of frailty and improve the treatment effect and quality of life of patients．

        目的   探讨临床特征联合外周血血管内皮生长因子（VEGF）与α-羟基丁酸脱氢酶（α-HBDH）对卵巢癌的诊断价值。方法   选取2022年6月—2024年6月在天津市中心妇产科医院妇科接收的84例卵巢癌恶性肿瘤患者纳入观察组，同期选取84例卵巢良性病变患者纳入对照组。对比两组患者临床资料及VEGF、α-HBDH水平的差异，分析VEGF、α-HBDH水平与卵巢癌恶性肿瘤患者临床特征的相关性。采用二元Logistics回归分析卵巢癌恶性肿瘤的独立危险因素，并采用受试者工作特征（ROC）曲线分析VEGF、α-HBDH水平诊断卵巢癌恶性肿瘤的价值。结果   观察组年龄、身体质量指数（BMI）及血清CA125、HE4、VEGF、α-HBDH水平显著高于对照组（P＜0.05），VEGF与α-HBDH水平与国际妇产科联盟（FIGO）分期、分化等级及淋巴结转移均呈正相关关系（P＜0.05）。将年龄、BMI、VEGF、α-HBDH作为自变量纳入二元Logistic回归，结果显示BMI、VEGF、α-HBDH是卵巢癌恶性肿瘤的影响因素（P＜0.05），ROC曲线分析显示，联合检测VEGF和α-HBDH的AUC达0.921，灵敏度和特异度分别为81.0%和91.7%，优于单独检测（VEGF：AUC=0.702；α-HBDH：AUC=0.796）。结论  BMI联合VEGF与α-HBDH检测可为卵巢癌的诊断提供高效、无创的辅助手段，具有重要临床应用潜力。

目的 探讨大黄穴位贴联合直肠指力刺激在脑卒中后便秘患者的应用效果。方法 本研究选择2019年1月—2019年12月间我院收治的脑卒中后便秘患者90例,随机分成A组(大黄穴位贴组),B组(直肠指力刺激组),C组(大黄穴位贴联合直肠指力刺激组)三组,每组30例。记录三组患者便秘治疗有效率,采用Wexner便秘评分系统评估三组患者治疗前后的便秘程度并进行自身前后对比。结果 三组干预前后Wexner评分采用自身配对非参数秩和检验,差异有统计学意义(P＜0.05)。三组干预前后差值采用Kruskal-Wallis H检验结果差异有统计学意义(H=26.211,P＜0.05),经过两两对比,差异有统计学意义(P＜0.05)。值得注意的是,干预后C组Wexner评分下降。干预后C组患者的有效率高于其他两组,有效率结果为C组(90%)＞B组(80%)＞A组(53.5%),差异有统计学意义(P＜0.05)。结论 相较于单一应用大黄穴位贴或直肠指力刺激,大黄穴位贴联合直肠指力刺激治疗效果更好,可有效降低便秘发生率,提高病人生活质量。

Objective To explore the effect of rhubarb acupoint application combined with rectal finger force stimulation in patients with constipation after stroke. Methods In this study, 90 patients with post-stroke constipation admitted to our hospital from January 2019 to December 2019 were randomly divided into group A (rhubarb acupoint application group), group B (rectal finger force stimulation group) and group C (rhubarb acupoint application combined with rectal finger force stimulation group), 30 cases in each group. The effective rates of constipation treatment in the three groups were recorded, and the Wexner constipation scoring system was used to evaluate the degree of constipation before and after treatment among three groups. Results The Wexner scores of the three groups before and after treatment were analyzed by self-paired non-parametric rank sum test, and the differences were statistically significant (all P<0.05). The difference among the three groups before and after treatment using Kruskal-Wallis H test was statistically significant (H=26.211, P<0.05), and after pairwise comparison, the differences were statistically significant (P<0.05). It was worth noting that the Wexner score of group C dropped significantly after treatment. The effective rate of treatment in group C was significantly higher that those in the other two groups. The result showed effective rate of group C (90%)＞ group B (80%)＞group A (53.5%), the difference was statistically significant (P<0.05). Conclusion Compared with the single treatment of rhubarb acupoint application or rectal finger force stimulation, the combined treatment had better efficacy, which reduced incidence of constipation and improved the quality of life of patients.

       目的   基于Nomogram初步构建膝骨关节炎（KOA）患者术前衰弱的风险预测模型。方法   便利选取172例于2021年12月—2022年8月在广州市某三甲医院关节外科接受择期膝关节置换术的KOA患者为研究对象，依据衰弱的发生与否分为衰弱组（n=111）和非衰弱组（n=61），通过单因素分析筛选变量，纳入Logistic回归分析，并构建列线图模型。结果   单因素分析结果显示年龄、BMI、膝关节疼痛年限、合并症、抑郁、焦虑、疼痛、睡眠障碍、营养状况等在不同组间比较差异存在统计学的意义（P＜0.05）。多因素Logistic回归分析表明，BMI异常（OR=3.360）、膝关节疼痛年限＞5年（OR=14.188）、抑郁（OR=5.608）、睡眠障碍（OR=25.480）是KOA患者术前衰弱的独立危险因素（P＜0.05）。基于此，建立了预测膝骨关节炎患者术前衰弱风险的列线图预测模型。结果显示C-index为0.915，校正曲线接近理想曲线，ROC曲线下面积（AUC）为0.919（95%CI：0.878~0.961），可见该预测模型具有较好的区分度和准确度。结论   根据BMI、膝关节疼痛年限、抑郁以及睡眠障碍这四个独立危险因素，可以准确地预测膝骨关节炎患者术前衰弱的风险。
