ABSTRACT. The aim of this study was to investigate the expression of vascular adhesion molecule (VCAM)-1 in the maternal serum, cord blood, and placental tissue of pregnant women from Xingtai, Hebei, with gestational hypertension (GH) combined with fetal growth restriction (FGR). A total of 108 patients with GH combined with FGR (GH-FGR), 60 patients with GH alone (GH), and 50 healthy pregnant women (control) were recruited to this study. VCAM-1 expression was detected in the maternal serum and cord blood by enzyme-linked immunosorbent assay, and in the placental tissue by immunohistochemistry. VCAM-1 expression was significantly higher in the maternal serum of patients with GH-FGR (164.38 ± 60.35) and GH alone (103.85 ± 54.47) than in the serum of the control population (46.70 ± 21.79; P < 0.05). On the other hand, VCAM-1 expression in the cord blood of , GH (149.82 ± 58.20), and control (128.89 ± 43.59) subjects was not significantly different (P > 0.05). Moreover, the VCAM-1 expression rates were significantly higher and lower in the vascular endothelial and trophoblastic cells of the placenta of patients with GH-FGR (74.71 and 56.1%) and GH (72.98 and 55.36%), respectively, compared to those in the control subjects (46.48 and 95.11%). Therefore, we concluded that VCAM-1 plays an important role in the development and generation of GH. Additionally, the low VCAM-1 expression in the trophoblastic cell could be correlated to the pathogenesis and progression of GH.

To investigate the effects of early nursing intervention on brain injury among premature infants, 100 premature infants diagnosed with brain injury were included in the research and randomly divided into the control group (50 cases) and the experimental group (50 cases). The patients in the two groups were performed with the same conventional comprehensive treatment. The patients in the control group received conventional nursing while those in the experimental group underwent early nursing intervention. During follow-up, neurodevelopment, motor behavior, the incidence rate of brain injury, and nursing satisfaction of the infants in the two groups were compared. It was demonstrated that the five neurodevelopment scores of the experimental group were all higher than those of the control group. The differences showed statistical significance ( P < 0.05 ). The total effective rate of motor development of the experimental group reached 94%, while that of the control group amounted to 80%. Obviously, the total effective rate of motor development of the experimental group was higher than that of the control group. The difference was statistically significant ( P < 0.05 ). The nursing satisfaction of the experimental group reached 98%, which was apparently higher than that of the control group (74%). The difference suggested statistical significance ( P < 0.05 ). The rates of brain injury at 1 and 2 years after the birth of the experimental group were 6% and 2%, respectively. The rates of brain injury at 1 and 2 years after the birth of the control group amounted to 18% and 14%, respectively. The rates of brain injury at 1 and 2 years after the birth of the experimental group were lower than those of the control group. The difference revealed statistical significance ( P < 0.05 ). Hence, the early nursing intervention of premature infants with brain injury could promote brain development, improve neurological function, reduce the incidence of brain injury, and achieve an ideal nursing effect.
