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．

目的 探讨前列地尔联合依帕司他对糖尿病足患者创面肉芽组织肿瘤坏死因子(tumor necrosis factor-α,TNF-α)、白介素-6 (interleukin-6,IL-6)及血管内皮生长因子(vascular endothelial growth factor,VEGF)表达的影响。方法 将90例糖尿病足患者随机分为研究组和对照组,每组45例,对照组予常规治疗,研究组在常规治疗基础上给予前列地尔+依帕司他联合治疗。监测两组患者创面愈合率,患肢足背血流动力学及腓总神经传导速度,创面肉芽组织TNF-α、IL-6、VEGF含量及基因表达变化。结果 治疗后第2、4周研究组较对照组创面愈合率升高,差异有统计学意义(P<0.05);治疗后两组患者足背动脉血流动力学及腓总神经传导速度均有改善,而研究组疗效更明显(P<0.05);治疗后研究组患者创面肉芽组织TNF-α、IL-6含量及基因表达较对照组降低,VEGF含量及基因表达则升高(P<0.05)。结论 前列地尔联合依帕司他联合治疗可改善糖尿病足患者足背动脉血流动力学,促进受损神经功能恢复;降低糖尿病足患者创面肉芽组织TNF-α、IL-6表达,减轻免疫损伤;增加VEGF基因表达,促进血管生成,加速创伤愈合。

Objective To investigate the effects of alprostadil combined with epalrestat on the expression of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and vascular endothelial growth factor (VEGF) in granulation tissue in patients with diabetic foot patients.Methods Totally 90 cases with diabetic foot were randomly divided into study group (45 cases)and control group(45 cases). The control group received conventional treatment for 4 weeks and the study group additionally received combination of alprostadil and epalatone for 4 weeks. The curative rate of wound healing, limb dorsal hemodynamics, peroneal nerve conduction velocity and the levels of TNF-α, IL-6 and VEGF in the granulation tissue of the wound were monitored in the two groups.Results The wound healing rate of the study group was significantly higher than that of the control group at the 2nd and 4th week after treatment (P<0.05). After treatment, the hemodynamics and peroneal nerve conduction velocity were improved (P<0.05). The contents and expressions of TNF-α and IL-6 in the granulation tissue of the treatment group were significantly lower than that of the control group, and the content of VEGF and gene expression were significantly increased in the study group (P<0.05).Conclusion The combination therapy of alprostadil and epalrestat may improve the hemodynamics of dorsalis pedis artery in patients with diabetic foot and promote the recovery of damaged nerve function.Also it may reduce the expression of TNF-α and IL-6 in the granulation tissue of diabetic patients and reduce the immune injury. It promotes angiogenesis and accelerates wound healing by increasing VEGF gene expression.
