风心病瓣膜置换术患者体外循环围术期细胞因子的释放

To examine cytokines release related to cardiopulmonary bypass(CPB), the anthers investigated the possible differences in cytokines responses between patients undergoing prosthetic valve replacement (study group, n = 10) and those receiving closure of patent ductus arteriosus or pericardiectomy(control group, n = 9). Venous levels of interleukin-2 (IL-2), soluble interleukin-2 receptor (sIL-2R), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), and interleukin-10 (IL-10) were measured at multiple time points before, during and after operation. As compared with pre-operative values, IL-2 levels in both groups decreased significantly (P < 0.05), and the levels of sIL-2R, IL-6, TNF-alpha, and IL-10 in both groups increased significantly at multiple time points post-operative (P < 0.01). All the values of cytokines returned to pre-operative levels at 7th post-operative day. Although there were no pre-operative differences in these cytokines between the two groups (P > 0.05), the post-operative changes of cytokines in study group was more obvious than that in control group (P < 0.01). In study group IL-10 rose to a peak value of around 620 pg/ml at the end of CPB while IL-6 and TNF-alpha levels reached their peak values of around 88 pg/ml and 52 pg/ml respectively at 1st post-operative day. IL-10 has been reported as an antiinflammatory cytokine. The preceding IL-10 peak value, as compared with the peak values of IL-6 and TNF-alpha, could be associated with the interplay and regulation of cytokine network. On the other hand, in control group the levels of IL-6, TNF-alpha, and IL-10 reached their peak values at 1st post-operative day simultaneously. The values were 34 pg/ml, 36 pg/ml, and 162 pg/ml respectively. This result suggests that besides surgical stress mediated cytokines production or suppression, CPB itself also results in obvious changes of cytokine metabolism. However further studies are needed to elucidate the underlying mechanisms and clinical value of post-operative cytokines production or suppression related to CPB in patients with prosthetic valve replacement.     

肾炎患者血清sIL－2R水平变化研究

应用双抗体夹心ＥＬＩＳＡ法检测急性肾炎、慢性肾炎、慢性肾功能不全患者共４８例血清ｓＩＬ－２Ｒ水平。结果显示，３组患者血清ｓＩＬ－２Ｒ水平均显著高于正常对照组（Ｐ＜０．０１），提示肾炎患者体内存在着淋巴细胞激活状态；对部分患者血清ｓＩＬ－２Ｒ水平进行动态观察发现，肾炎患者随病情好转或痊愈，血清ｓＩＬ－２Ｒ的水平下降或恢复正常。     

CHANGES ON RECEPTOR EXPRESSION AND PRODUCTION OF INTERLEUKIN-2 IN CIRCULATING LYMPHOCYTE POPULATION AFTER OPEN HEART SURGERY

To evaluate the change of perioperative ceil mediated immunity after cardiac operation with cardiopulmonary bypass (CPB), so as to provide some information for timely prevention and treatment against postoperative immtmological disorder, 40 patieuts were studied. By searching for the effects of CPB and anesthesia, interleukin-2 receptor(IL-2R) expression upon the sttrface of peripheral blood mononuclear cells (PBMC), as well as interleukin-2 (IL-2) production in vitro was traced 55 rain after anesthesia, at end of CPB, on postoperative 1, 7, and 14 day versus preanesthesia control. Our data demonstrated that expression of IL-2R on PBMC was significantly suppressed in all comparing with the baseline value, meanwhile,IL-2 production in vitro also statistically dropped. However,no statistical difference was found on perloperative IL-2R expression and IL-2 synthesis in the cholecystectomy group. We conclnde that postoperative immunological disorder seems to be the main factor, which could be denoted as reduced IL-2R expression on PBMC and IL-2 synthesis m vitro for sepsis, even multiple system organ failure developed after cardiac surgery.

Changes and clinical significances of serum soluble interleukin-2 receptor in patients with mechanical trauma

Objective: To study the changes of serum level of soluble interleukin-2 receptor (sIL-2R) in patients with mechanical trauma and the relationship between sIL-2R serum level and injury severity score (ISS), and to explore the mechanism of changes and clinical significances of sIL-2R. Methods: According to the criterion of ISS, 50 patients with mechanical trauma were divided into mild degree group, severe degree group and extremely severe degree group. Twenty-five of those were dynamically observed for 12 d. Blood samples of all the patients were obtained within 24 h, and ond3,d5,d7,d9 and d 12 in dynamically observed patients. The serum concentration of sIL-2R was assayed by ELISA. Results: Level of sIL-2R was significantly higher in patients with trauma than that in healthy persons within 24 h (P<0. 05). Dynamical observation showed curving changes of sIL-2R with increasing in early stage and decreasing later. The climax of sIL-2R appeared earlier in mild group than that in severe degree group and extrem

应用双抗体夹心ELISA法检测了48例恶性实体瘤患者血清SIL－2R水平，发现荷瘤患者血清的SIL－2R均明显高于对照者，伴转移者的SIL－2R高于不伴转移者；根治性切除后，血清SIL－2R明显下降，而姑息性切除者则无明显变化；术后复发时已下降的SIL－2R再次升高。提示血清SIL－2R可作为恶性肿瘤患者病情估计、疗效评价和术后复发的监测指标。     

血清IL-2和SIL-2R在胆道梗阻围手术期中的变化及精氨酸治疗的研究

目的 探讨胆道梗阻病人围手术期血清白细胞介素-2（IL-2）活性和可溶性白细胞介素-2爱体（SIL-2R）水平及精氨酸的免疫调节作用。方法 选择1组胆道梗阻病人，按疾病的良恶性分为两组，分别采用放免计数器和双抗体夹心ELISA法测定血清IL-2和SIL-2R水平。另择1组良性胆道梗阻病人术前行为期7d的精氨酸治疗，检测其血清IL-2及SIL-2R．水平的变化。结果 良恶性两组术前血清IL-2较对照组明显降低，SIL-2R．明显高于对照组，术后逐渐恢复，但良恶性两组变化幅度差异明显；血清总胆红素水平与血清IL-2及SIL-2R水平之间密切相关；在良性组，胆道外引流术式较胆道内引流术式相对不利于血清IL-2和SIL-2R水平的恢复；精氨酸可上调良性胆道梗阻病人血清IL-2水平，抑制血清SIL-2R过表达。结论 胆道梗阻病人体内存在着血清IL-2活性降低和SIL-2R过度表达，检测血清IL-2和SIL-2R有助于估价病情、判断预后及鉴别胆道梗阻的性质，胆道外引流相对不利于血清IL-2和SIL-2R的恢复，可能与胆汁酸盐丢失导致肠道细茵易位和肠源性内毒素血症有关，精氨酸通过提高血清IL-2活性，抑制血清SIL-2R表达而发挥其免疫调节作用。
