To investigate the relationship between hepatocyte growth factor (HGF) and vascular endothelial cells (VEC) in pregnancy induced hypertension (PIH).Twenty women with PIH (6 mild, and 14 moderate or severe PIH) and 20 women with normal pregnancy were recruited as study group and control group, respectively. The two groups were matched in maternal age, parity and gestational age. Flow cytometer was used for counting the number of peripheral blood circulating endothelial cells (CEC), while enzyme-linked immunoabsorbent assay (ELISA) was used to measure the concentration of serum HGF.In the study group, the concentration of HGF was (1395 +/- 512) ng/L, and the number of CEC was (109,360 +/- 24,070) /L. In the control group, the concentration of HGF was (1565 +/- 399) ng/L, and the number of CEC was (21,800 +/- 4420)/L. The differences both in the concentration of HGF and the number of CEC between the two groups were statistically significant (P < 0.01). Negative correlation between CEC and HGF was found both in study group and control group (r = -0.608, P < 0.01).Decreased HGF may be related to VEC damage in the development of PIH.
In the criticism circle of poetry, poems, cantus, ballads, proverbs are all listed under the category of poetry, which is regarded as being not appropriate in this article. Poems, ballads, cantus and proverbs all come from the same origination but develop differently in nature, cause, purpose, and direction. To clarify the nature of poetry, poems, cantus, ballads and proverbs, and the relations between them are of significance for a better understanding of the development of Chinese and the guiding principle that poetry speaks ideal.
Chinese income inequality has continuously increased since the early 1990s. We estimate separate labor income processes for the workers in three different sectors. Agricultural workers face the highest degree of income uncertainty and the lowest average income level; while workers in the private sector face significantly larger risk and lower average income than workers in the non-private sector. The level of income inequality does not seem to increase over time within each of these sectors, but there is a large increase in inequality across sectors. The combination of these heterogeneous income processes and demographic data generates an evolution of the income distribution that is comparable to that reported in Piketty et al. (2019).
