RESUMEN
OBJECTIVE: To investigate the change of the hs-CRP, sVCAM-1, NT-proBNP levels of the patients with pregnancy-induced hypertension (PIH) syndrome. METHODS: A total of 200 patients with PIH were divided into mild, moderate and severe group, and 50 healthy pregnancy patients served as the control group. The serum sVCAM-1 levels were detected by enzyme-linked immunosorbent assay, hs-CRP were detected by immunity transmission turbidity, and NT-proBNP levels were determined by the colloidal gold method. Patients were treated with magnesium sulfate and nifedipine and the contrastive analysis was performed before and after treatment. And the pathological changes in placental of PIH patients were detected by hematoxylin-eosin staining at the same time. RESULTS: The hs-CRP, sVCAM-1, NT-proBNP levels of patients in the mild, moderate and severe PIH group were significantly higher than that in the control group (P<0.05). The hs-CRP, sVCAM-1, NT-proBNP levels in the severe group were significantly higher than the mild group and the moderate group, the difference was statistically significant (P<0.05). The hs-CRP, sVCAM-1, NT-proBNP of the moderate group were significantly higher than the mild group (P<0.05). There was a positive correlation between hs-CRP, sVCAM-1, NT-proBNP expression levels and the degree of the PIH. The expression of hs-CRP, sVCAM-1, NT-proBNP levels of the moderate and the severe group were significantly decreased (P<0.05). The number of placental villi and interstitial blood vessel in the moderate and severe PIH group were significantly less than the control group (P<0.05). CONCLUSIONS: The increased levels of serum hs-CRP, sVCAM-1, NT-proBNP may be involved in the process of vascular endothelial cell injury of the PIH, and the hs-CRP, sVCAM-1, NT-proBNP can be used as the auxiliary index for diagnosis of PIH and determination of PIH severity.
