文题释义:
血液透析:是急慢性肾功能衰竭患者肾脏替代治疗方式之一,它通过将体内血液引流至体外,经一个由无数根空心纤维组成的透析器中,血液与含机体浓度相似的电解质溶液(透析液)在一根根空心纤维内外,通过弥散/对流进行物质交换,清除体内的代谢废物、维持电解质和酸碱平衡;同时清除体内过多的水分,并将经过净化的血液回输的整个过程。通过血液透析治疗,可以对患者体内存在的各种毒素等予以有效清除,并为患者提供机体所需的营养物质,达到维持内稳态平衡、治疗疾病的目的。
透析膜材料:聚砜膜和醋酸纤维素膜是两种常用的膜材料,聚砜膜属于合成膜,具有较高的超滤系数;纤维素膜通透性高,亲水性高,具有较强的毒素清除能力。两种材料具有强度高、耐磨、无毒等优点,可以在治疗过程中达到有效清除各种毒素等效果,达到治疗疾病的目的。

背景:对重症胰腺炎进行血液透析治疗时,可选用不同的透析膜材料,不同透析膜材料生物相容性是否存在差异?
目的:对比聚砜膜和醋酸纤维素膜透析膜材料的生物相容性。
方法:纳入100例重症胰腺炎患者,其中男51例,女49例,年龄34-81岁,均接受血液透析治疗,其中50例采用聚砜膜,另50例采用醋酸纤维素膜,透析5 h/次,3次/周。透析3个月后,比较两组透析后的腹痛与腹胀有效缓解时间、血淀粉酶水平恢复至正常水平的时间、治疗有效率及炎性因子水平的变化。
结果与结论:聚砜膜组与醋酸纤维素膜组血淀粉酶水平恢复至正常水平的时间、腹痛及腹胀有效缓解时间、治疗有效率比较差异无显著性意义。两组透析后的白细胞介素6、C-反应蛋白、肿瘤坏死因子α水平均显著低于透析前(P < 0.05),但两组之间比较差异均无显著性意义。结果表明对重症胰腺炎患者进行血液透析治疗时,使用聚砜膜和醋酸纤维素膜两种膜材料均具有良好的生物相容性。

Abstract:

BACKGROUND: In the clinical treatment of severe acute pancreatitis, there are different dialysis membrane materials. But the differences among these dialysis membrane materials are unclear.
OBJECTIVE: To compare the biocompatibility of polysulfone and cellulose acetate dialysis membranes.
METHODS: Totally 100 severe acute pancreatitis patients were included, including 51 males and 49 females, aged 34 to 81 years, and all were subjected to hemodialysis treatment (5 hours once, three times per week). Polysulfone membrane was used in 50 cases, and cellulose acetate dialysis membrane used in the other 50 cases. After 3 months of follow-up, the time of recovery from abdominal pain and abdominal distension, the time of blood amylase returning to normal levels, therapeutic efficacy and level of inflammatory factors were compared between two groups.
RESULTS AND CONCLUSION: There were no differences in the time of recovery from abdominal pain and abdominal distension, the time of blood amylase returning to normal levels, and therapeutic efficacy between the two groups. The levels of interleukin-6, C-reactive protein and tumor necrosis factor alpha in the two groups were significantly lower than those before hemodialysis treatment (P < 0.05), but there was no significant difference between the two groups. Results show that both polysulfone and cellulose acetate membranes used in hemodialysis treatment of severe acute pancreatitis have good biocompatibility.
