VSD引流术结合重组人碱性成纤维细胞生长因子及液体敷料对糖尿病足溃疡的临床疗效及疼痛影响观察

目的:探讨负压封闭引流术(VSD)结合重组人碱性成纤维细胞生长因子及液体敷料对糖尿病足溃疡的临床疗效及疼痛影响观察.方法:选取2019年5月～2021年5月期间某院收治的98例糖尿病足溃疡患者作为研究对象,随机将所有患者分为研究组和对照组各49例,研究组采用VSD引流术结合重组人碱性成纤维细胞生长因子及液体敷料进行治疗,给予对照组普通换药治疗方式,并对比两组患者临床疗效及对患者疼痛程度的影响.结果:研究组临床总有效率为95.92％,明显高于对照组的73.47％(P<0.05);治疗7d及治疗14d后,研究组目前疼痛状况(PPI)、视觉模拟评定法(VAS)、疼痛评级指数(PRI)评分均明显低于对照组(P<0.05);研究组换药次数明显少于对照组,创面愈合时间、抗生素使用时间及住院时间均明显短于对照组(P<0.05).结论:针对糖尿病足溃疡患者,采用VSD引流术结合重组人碱性成纤维细胞生长因子及液体敷料对其进行治疗,可有效促进创面愈合、减轻患者疼痛程度,能够减少患者换药次数与抗生素使用时间,缩短患者创面愈合时间与住院时间,临床疗效较好,值得应用.

Synthesis and automated fluorine-18 radiolabeling of new PSMA-617 derivatives with a CuAAC radiosynthetic approach

In the last decade, the development of new radiopharmaceuticals for the imaging and therapy of prostate cancer has been a highly active and important area of research, especially focusing on the prostate-specific membrane antigen (PSMA), an antigen which is upregulated in prostate, as well as in other tumor cells. A large variety of PSMA ligands have been radiolabeled, to date. Among the various derivatives, PSMA-617 resulted to be one of the most interesting in terms of interaction with the antigen and clinical properties, and its lutetium-177 labeled version has recently been approved by regulatory agencies for therapeutic purposes. For this reasons, the radiolabeling with fluorine-18 of a PSMA-617 derivative might be of interest. Beside other methodologies to radiolabel macromolecules with fluorine-18, the “click-chemistry” approach resulted to be very useful, and the copper-catalyzed azide-alkyne cycloaddition (CuAAC) is considered one of most efficient and reliable. This paper proposes the synthesis of a suitable precursor for the radiolabeling with fluorine-18 of a new PSMA-617 derivative. The whole radiosynthetic procedure has been fully automated, and the final product, which proved to be stable in plasma, has been obtained with radiochemical yield and purity suitable for subsequent preclinical studies.
