Objective To predict the osteoporotic fracture risk in senile people in Guangzhou communities by FRAX,the fracture risk assessment tool published by WHO. Methods Clinical data of 1140 cases were collected for the retrospective analysis. The FRAX tool was uesed to calculate the 10-year probability of a major osteoporotic and hip fracture.The relationship between different risk factors and the fracture risk predicted by FRAX was analyzed. Results The 10-year probability of major osteoporotic fractures was (4.2±3.6)%, and the 10-year probability of hip fractures was (1.3±2.4)%.The 10-year probability of the major osteoporotic and hip fracture increased with age.Multivariate regression analysis showed that age,gender,previous fracture,secondary osteoporosis,T-score of femoral neck BMD and fall were independent predictors of the 10-year probability of major osteoporotic fracture and hip fracture. Conclusion The FRAX tool may be effectively applied to assess the fracture risk of senile population in Guangzhou communities.We recommedated that FRAX-tool should be included in routine health check-up.

目的 探究血清多配体蛋白聚糖-1（SCD-1）与可溶性血管内皮生长因子受体-2（sVEGFR-2）表达水平在老年慢性心力衰竭患者预后评估的判定价值。方法 选取2023年1月—2024年3月珠海市第五人民医院检验科收治的110例老年慢性心力衰竭患者,检测其血清SCD-1和sVEGFR-2水平,对患者进行随访调查,了解其再次由于心力衰竭住院、心源性死亡的情况。运用多因素Logistic回归分析,探究老年慢性心力衰竭患者预后影响因素。结果 Logistic回归分析显示,心功能分级（OR=3.433,95%CI：0.934~6.431）、B型脑钠肽升高（OR=2.462,95%CI：0.861~4.765）、血清SCD-1升高（OR=3.795,95%CI：0.972~6.894）、血清sVEGFR-2升高（OR=3.842,95%CI：0.942~6.912）为影响老年慢性心力衰竭患者预后不良的重要因素（P<0.05）;联合血清SCD-1和sVEGFR-2曲线下面积0.962与B型脑肽钠曲线下面积0.844,相较于单一SCD-1曲线下面积0.658、sVEGFR-2曲线下面积0.712明显偏高（P<0.05）。结论 经研究证实,老年慢性心力衰竭患者预后效果不理想,其血清SCD-1和sVEGFR-2监测水平异常升高,和老年慢性心力衰竭预后不佳存在关联性,可视为老年慢性心力衰竭患者判定预后效果的主要标志物。

Objective To investigate the prognostic value of serum syndecan-1（SCD-1）and soluble vascular endothelial growth factor receptor-2（sVEGFR-2）expression levels in elderly patients with chronic heart failure. Methods A total of 110 elderly patients with chronic heart failure admitted to our hospital were selected,with a time interval of January 2023 to March 2024．Serum SCD-1 and sVEGFR-2 levels were detected and follow-up investigations were conducted to understand their re hospitalization and cardiogenic death due to heart failure．Multiple logistic regression analysis was used to explore the prognostic factors affecting elderly patients with chronic heart failure. Results According to logistic retrospective analysis,heart function grading（OR=3.433,95%CI：0.934-6.431）,elevated B-type brain natriuretic peptide（OR=2.462,95%CI：0.861-4.765）,elevated serum SCD-1（OR=3.795,95%CI：0.972-6.894）,and elevated serum sVEGFR-2（OR=3.842,95%CI：0.942-6.912）were important factors affecting the poor prognosis of elderly patients with chronic heart failure,with differences P<0.05．The area under the curve of combined serum SCD-1 and sVEGFR-2 was 0.962,and the area under the curve of B-type brain peptide sodium was 0.844,which was significantly higher than that of a single SCD-1 curve of 0.658 and sVEGFR-2 curve of 0.712,with a difference of P<0.05. Conclusions Research has confirmed that the prognosis of elderly patients with chronic heart failure is not satisfied,and their serum SCD-1 and sVEGFR-2 monitoring levels are abnormally elevated,which is related to the poor prognosis of elderly patients with chronic heart failure．It can be regarded as the main biomarker for defining the prognosis of elderly patients with chronic heart failure．
