目的 探讨进食时机对尿毒症血液透析患者的影响,为临床上此类研究提供参考依据。方法 选取2018年5月—2020年5月于我院进行血液透析的患者42例,根据自身随机对照法分为A组（n=21）和B组（n=21）。A组患者前六次在血液透析1.5 h时进食,后六次在血液透析2.5 h时进食;B组患者前六次在血液透析2.5 h时进食,后六次在血液透析1.5 h时进食。观察比较1.5 h和2.5 h进食的患者在血液透析前以及血液透析中不同时间点的血压和血糖。结果 2组患者在不同时间点的血压值和低血压发生率比较差异无统计学意义（P>0.05）;血液透析1.5 h进食患者在透析2 h和3 h时血糖值明显高于2.5 h进食患者,比较差异具有统计学意义（P<0.05）;血液透析1.5 h进食的患者在透析2 h时低血糖的发生率显著低于2.5 h进食患者,差异具有统计学意义（P<0.05）。结论 对尿毒症血液透析患者来说,于血液透析1.5 h进食能够有效降低患者低血压和低血糖的发生几率。

Objective To discuss the influence of eating timing on uremic hemodialysis patients,and to provide a reference for this kind of clinical research．Methods A total of 42 patients undergoing hemodialysis were selected in our hospital from May 2018 to May 2020 and were divided into group A（n=21）and group B（n=21）according to self randomized control method．Patients in group A ate at 1.5 hour of hemodialysis for the first six times,and at 2.5 hour of hemodialysis for the last six times;patients in group B ate at 2.5 hour of hemodialysis for the first six times,and at 1.5 hour of hemodialysis for the last six times．Observed and compared the blood pressure and blood sugar of patients who eat at 1.5 hour and 2.5 hour before hemodialysis and at different time points during hemodialysis．Results There were no significant differences in blood pressure and the incidence of hypotension between the two groups of patients at different time points（P>0.05）;the blood glucose levels at 2 and 3 hour of the patients who ate at 1.5 hour of hemodialysis was significantly higher than that of the patients who ate at 2.5 hour,and the difference was statistically significant（P<0.05）;the incidence of hypoglycemia at 2 hour of hemodialysis in patients who ate at 1.5 hour was significantly lower than that of patients who ate at 2.5 hour,and the difference was statistically significant（P<0.05）．Conclusions For uremic hemodialysis patients,eating at 1.5 hour of hemodialysis could effectively reduce the incidence of hypotension and hypoglycemia．

目的 分析接受自体动静脉内瘘（AVF）维持性血液透析（MHD）尿毒症患者AVF使用寿命的影响因素,以期为临床延长AVF使用寿命提供可参考依据。方法 选取我院2019年1月—2021年2月期间收治的接受AVF的367例MHD尿毒症患者为研究对象,随访1年,统计AVF功能丧失状况,将AVF功能丧失患者纳入丧失组,AVF通畅患者纳入通畅组,分析AVF使用寿命的影响因素。结果 随访1年,AVF通畅率为80.65%（296/367）,功能丧失率为19.35%（71/367）;不同糖尿病、血液透析中低血压（IDH）、血磷、低密度脂蛋白、钙磷乘积、高凝倾向、前壁动静脉内径、血肿状况为AVF MHD尿毒症患者的AVF寿命存在差异（P<0.05）;经COX回归模型分析显示,糖尿病、IDH、血磷≥2.04 mmol/L、低密度脂蛋白>2.38 mmol/L、高凝倾向、血肿、前壁动静脉内径<2 mm为AVF MHD尿毒症患者AVF功能丧失的独立危险因素（P<0.05）。结论 AVF MHD尿毒症患者AVF使用寿命受糖尿病、IDH、血磷≥2.04 mmol/L、低密度脂蛋白>2.38 mmol/L、高凝倾向、血肿、前壁动静脉内径<2 mm等因素影响,临床可针对性制定干预措施以延长AVF使用寿命。

目的 探究尿毒症继发性甲状旁腺功能亢进经甲状旁腺切除术治疗效果及安全性分析。方法 选取2017年6月—2019年5月于我院就诊的90例尿毒症继发性甲状旁腺功能亢进患者为研究对象,随机分为对照组与观察组,两组各45例。均采取同一药物治疗,对照组行次全切除治疗,观察组行甲状旁腺全切除术+前臂移植术。对比分析两组治疗效果、血生化指标及并发症。结果 观察组疗效优于对照组(P<0.05);观察组术后1周、1个月钙、iPTH、磷、钙磷乘积及ALP水平均低于对照组(P<0.05);观察组并发症发生率低于对照组(P<0.05)。结论 甲状旁腺全切除+前臂移植治疗尿毒症继发性甲状旁腺功能亢进疗效显著,并发症风险低,值得推广。
