研究非精氨酸（A组）37例（含14例AOSC）和精氨酸组（B组）29例（含11例AOSC）细胞免疫变化和围手术期感染性并发症。结果显示：无论手术前，还是手术后B组CD3+、CD4+显著高于A组（P＜0．01），而B组SIL－2R显著低于A组（P＜0．01）。在AOSC术后，B组体温、WBC计数明显低于A组（P＜0．01），A组术后感染性并发症非常显著高于B组（P＜0．01）。研究表明精氨酸有显著改善梗阻性黄疸围手术期细胞免疫功能作用、增强机体抗感染能力和显著降低术后感染性并发症的发生。
To study the cellular immune changes and perioperative infectious complications in 29 cases (including 11 cases of AOSC) of non-arginine (group A), 37 cases (14 cases of AOSC) and arginine group (group B). The results showed that CD3 + and CD4 + in group B were significantly higher than those in group A (P <0.01) before surgery or after operation, while in group B, SIL-2R was significantly lower than that in group A (P <0.01). After AOSC surgery, the body temperature and WBC count in group B were significantly lower than those in group A (P <0.01). The postoperative infectious complications in group A were significantly higher than those in group B (P <0.01). Studies have shown that arginine significantly improves perioperative cellular immune function in patients with obstructive jaundice, enhances the body’s anti-infective ability and significantly reduces postoperative infectious complications.
