Eighty EM patients [American Reproductive Association stage Ⅰ （n=20）, stage Ⅱ （n=22）, stage Ⅲ （n=21） and stage Ⅳ （n=17）] were enrolled and divided into mild （10- 14 points, n=28）, moderate （16-24 points, n=27） and severe （26-30 points, n=25） dysmenorrhea groups. The control group included 40 healthy women of childbearing age who underwent routine healthcare examinations in the enrolment period. The expression of MMIF, HIF- 1α and VEGF in the serum and endometrial tissues was measured by enzyme-linked immunosorbent assay and Western blotting, respectively. Meanwhile, the sensitivity and specificity of serum MMIF, HIF-1α, and VEGF when separately used as single indexes or jointly used as one index were examined as well. The results showed that serum concentrations of MMIF, HIF-1α, and VEGF were significantly higher in EM patients than in controls （P〈0.05）. The expression of all three proteins in both serum and endometrial tissues increased significantly with the R-AFS stage （P〈0.05） and with dysmenorrheal severity （P〈0.05）. The sensitivity and specificity of the combined detection of serum MMIF, HIF-1α, and VEGF levels were significantly higher than those of single index detection （P〈0.05）. In conclusion, the expression of MMIF, HIF-1α, and VEGF in the serum and endometrial tissues may be used to assess the stage of EM and the severity of dysmenorrhea. Combined evaluation of MMIF, HIF-1α, and VEGF significantly improves the diagnostic sensitivity and specificity.展开更多

Methods: The serum concentrations of MIF, TNF-α and IL-6 in 18 patients with chronic virus hepatitis B and in 14 patients with hepatitis cirrhosis without as- citic fluid, and the serum and ascites cytokine con- centrations in 22 HC patients with ascitic fluid were detected by enzyme linked immunity sorbed assay. Results: The cytokine concentrations of the patients were significantly higher than those of the controls. The serum levels of MIF, TNF-α and IL-6 of the 22 patients with ascitic fluid were higer than those of 14 HC patients without ascites. In the 18 patients with CH, the serum cytokine concentrations were the low- est. The serum cytokine concentrations of the 22 HC patients with ascites were significantly higher than those of the 14 HC patients without ascites (P< 0. 01). Their serum cytokine concentrations were sig- nificantly higher than those in the 18 patients with CH (P<0. 01). The concentration of IL-6 in ascites was the highest among all the groups. The serum le- vels of MIF, TNF-α and IL-6 are correlated with al- anine aminotransferase (ALT) in the patients with CH, but not in those with HC with or without asci- tes. Conclusions: These results indicated that MIF, TNF- α and IL-6 may participate in the pathological process of CH and cirrhosis, that IL-6 seems to play an important role in ascites formation, and that se- rum levels of MIF, TNF-α and IL-6 appear to reflect the severity of tissue injury in HBV disease.展开更多
文摘目的：观察巨噬细胞移动抑制因子（MMIF）、血管生成素-2（Ang -2）、血管内皮生长因子（VEGF）在子宫内膜异位症（EMs）检测中的临床意义。方法选取2011年1月至2014年6月经病理确诊的 EMs 患者98例，为异位内膜组。按照美国生殖协会分期标准（R - AFS）分期分为Ⅰ期26例、Ⅱ期29例、Ⅲ期22例和Ⅳ期21例；按照痛经评分0~1分57例和2~3分42例。选择同期确诊的良性肿瘤患者30例为在位内膜组。同时选择同期体检的健康妇女30例，为健康对照组。观察各组血清 MMIF、VEGF 和 Ang -2水平，以及 MMIF、VEGF 和 Ang -2水平与 EMs 分期和痛经评分的关系。结果异位内膜组和在位内膜组的 MMIF、VEGF 和 Ang -2水平明显高于正常对照组（ P 〈0.01），而异位内膜组的 MMIF、VEGF 和 Ang -2水平明显高于在位内膜组（ P 〈0.01）。EMs 患者的 MMIF、VEGF 和 Ang -2水平随着r - AFS 分期级别和痛经评分的升高而升高（ P 〈0.05或 P 〈0.01）。结论 MMIF、VEGF 和 Ang -2参与了 EMs 的发生和发展，有望成为 EMs 诊断和靶向治疗提供新的思路。
