目的:探讨脓毒症大鼠血清炎症递质的变化。方法将30只雄性 SD 大鼠随机分为假手术组10只和脓毒症组20只,采用盲肠结扎穿孔法制作脓毒症模型。采集假手术组造模后颈总动脉血,采集脓毒症组造模后0、24、48、72 h 颈总动脉血,用酶联免疫吸附法检测血清肿瘤坏死因子α(TNF-α)、白细胞介素1(IL-1)、白细胞介素6(IL-6)的浓度。结果假手术组血清 TNF-α为(9.27±3.12)ng/ L,脓毒症组造模后0、24、48、72 h 分别为(9.26±8.01)、(32.01±4.52)、(55.22±7.61)、(83.31±8.57) ng/ L,脓毒症组造模后24、48、72 h 与造模后0 h 和假手术组比较差异均有统计学意义(P 均<0.01);假手术组血清 IL-1为(8.93±1.26)ng/ L,脓毒症组造模后0、24、48、72 h 分别为(20.01±3.51)、(25.51±2.79)、(59.67±3.26)、(87.86±11.51)ng/ L,脓毒症组造模后24、48、72 h 与造模后0 h 和假手术组比较差异均有统计学意义(P 均<0.01);假手术组血清 IL-6为(12.36±3.25)ng/ L,脓毒症组造模后0、24、48、72 h 分别为(11.52±2.32)、(31.59±12.12)、(57.27±13.53)、(71.59±12.67)ng/ L,脓毒症组造模后24、48、72 h 与造模后0 h 和假手术组比较差异均有统计学意义(P 均<0.01)。结论脓毒症大鼠血清炎症递质水平明显升高,提示机体过度释放大量炎症递质,可能是导致脓毒症发生的因素之一。
目的:探討膿毒癥大鼠血清炎癥遞質的變化。方法將30隻雄性 SD 大鼠隨機分為假手術組10隻和膿毒癥組20隻,採用盲腸結扎穿孔法製作膿毒癥模型。採集假手術組造模後頸總動脈血,採集膿毒癥組造模後0、24、48、72 h 頸總動脈血,用酶聯免疫吸附法檢測血清腫瘤壞死因子α(TNF-α)、白細胞介素1(IL-1)、白細胞介素6(IL-6)的濃度。結果假手術組血清 TNF-α為(9.27±3.12)ng/ L,膿毒癥組造模後0、24、48、72 h 分彆為(9.26±8.01)、(32.01±4.52)、(55.22±7.61)、(83.31±8.57) ng/ L,膿毒癥組造模後24、48、72 h 與造模後0 h 和假手術組比較差異均有統計學意義(P 均<0.01);假手術組血清 IL-1為(8.93±1.26)ng/ L,膿毒癥組造模後0、24、48、72 h 分彆為(20.01±3.51)、(25.51±2.79)、(59.67±3.26)、(87.86±11.51)ng/ L,膿毒癥組造模後24、48、72 h 與造模後0 h 和假手術組比較差異均有統計學意義(P 均<0.01);假手術組血清 IL-6為(12.36±3.25)ng/ L,膿毒癥組造模後0、24、48、72 h 分彆為(11.52±2.32)、(31.59±12.12)、(57.27±13.53)、(71.59±12.67)ng/ L,膿毒癥組造模後24、48、72 h 與造模後0 h 和假手術組比較差異均有統計學意義(P 均<0.01)。結論膿毒癥大鼠血清炎癥遞質水平明顯升高,提示機體過度釋放大量炎癥遞質,可能是導緻膿毒癥髮生的因素之一。

Objective To investigate the changes of serum inflammatory mediators in septic rats. Methods Thirty male SD rats were randomly divided into sham operation group(10 rats)and sepsis group (20 rats). The model of sepsis was made by cecal ligation and puncture. Carotid artery blood samples were taken from the sham operation group,and from sepsis group at 0,24,48,72 h after model establishment. Enzyme linked immunosorbent assay(ELISA)was applied to detect the content of serum tumor necrosis factor alpha(TNF α), interleukin 1(IL-1),interleukin element 6(IL-6). Results Serum TNF-α content in the sham operation group was(9. 27 ± 3. 12)ng/ L,and(9. 26 ± 8. 01),(32. 01 ± 4. 52),(55. 22 ± 7. 61),(83. 31 ± 8. 57)ng/ L respectively at 0,24,48,72 h after model establishment in sepsis group. There were significant difference between sham operation group and sepsis group at different time points(P < 0. 01). Serum IL-1in sham operation group was(8. 93 ± 1. 26)ng/ L,lower than that in sepsis group model at 0,24,48,72 h after model establishment ((20. 01 ± 3. 51),(25. 51 ± 2. 79),(59. 67 ± 3. 26),(87. 86 ± 11. 51)ng/ L respectively),and the differences were significant(P < 0. 01). The serum IL-6 level in sepsis group at 0,24,48,72 h after model establishment were(11. 52 ± 2. 32),(31. 59 ± 12. 12),(57. 27 ± 13. 53),(71. 59 ± 12. 67)ng/ L,respectively,different from that of sham operation group((12. 36 ± 3. 25)ng/ L,(P < 0. 01)). Conclusion The serum transmitter levels in septic rats significantly increase,which suggest that a lot of inflammatory mediators are released,and it may be one of the factors for the occurrence of sepsis.
