【摘要】：目的探讨不同控制性超促排卵(controlled ovarian hyperstimulation,COH)方案中血清及卵泡液(follicular fluid,FF)中血管内皮生长因子(vascular endothelial growth factor,VEGF)与抑制素B(inhibin B,INHB)及COH结局的相关性。方法应用酶联免疫吸附方法分别检测长方案组(A组,n=38)及非降调节方案组(B组,n=38)患者血清及FF中VEGF和INHB水平并行相关性分析。结果 1降调节足够长时间(≥18 d)时,血清VEGF水平显著下降,且促性腺激素(Gn)启动日A组VEGF水平[(81.50±32.59)ng/L]明显低于B组[(123.64±53.90)ng/L](P0.01)。2 Gn启动后A、B组血清VEGF水平呈上升趋势,h CG注射日后A组继续上升,而B组先下降后上升;且h CG注射次日A组VEGF水平[(165.69±38.25)ng/L]明显高于B组[(136.49±39.19)ng/L](P=0.002);A、B组其它时间血清VEGF水平无统计学差异(P0.05)。3 Gn第5日血清VEGF水平与COH结局相关性最好(P0.01)。4 A、B组FF中VEGF水平随卵泡直径增大而升高,大、中卵泡VEGF水平无统计学差异(P0.05),但B组小卵泡VEGF水平[(889.86±268.95)ng/L]明显高于A组[(728.45±291.88)ng/L](P=0.014);且大卵泡VEGF水平与COH结局显著呈负相关。5 A、B组血清及FF中VEGF水平与INHB呈显著负相关。结论 COH过程中,血清及大、中卵泡VEGF水平与卵巢反应性及COH结局负相关,并且可能对INHB分泌起抑制作用。
[Abstract]:Objective to investigate the relationship between vascular endothelial growth factor (vascular endothelial growth factor,VEGF) in serum and follicular fluid (follicular fluid,FF) and the outcome of COH in different controlled hyperstimulation of ovulation (controlled ovarian hyperstimulation,COH). Methods Enzyme-linked immunosorbent assay (Elisa) was used to detect the levels of VEGF and INHB in serum and FF of patients with long regimen (group A, nong38) and non-descending regimen (group B, group B), respectively. Results (1) the serum VEGF level decreased significantly after long enough down-regulation (鈮，
