Abstract
MicroRNAs (miRs) are known to have an important role in modulating vascular biology. MiR21 was found to be involved in the pathogenesis of proliferative vascular disease. The role of miR21 in endothelial cells (ECs) has well studied in vitro, but the study in vivo remains to be elucidated. In this study, miR21 endothelial-specific knockout mice were generated by Cre/LoxP system. Compared with wild-type mice, the miR21 deletion in ECs resulted in structural and functional remodeling of aorta significantly, such as diastolic pressure dropping, maximal tension depression, endothelium-dependent relaxation impairment, an increase of opening angles and wall-thickness/inner diameter ratio, and compliance decrease, in the miR21 endothelial-specific knockout mice. Furthermore, the miR21 deletion in ECs induced down-regulation of collagen I, collagen III and elastin mRNA and proteins, as well as up-regulation of Smad7 and down-regulation of Smad2/5 in the aorta of miR21 endothelial-specific knockout mice. CTGF and downstream MMP/TIMP changes were also identified to mediate vascular remodeling. The results showed that miR21 is identified as a critical molecule to modulate vascular remodeling, which will help to understand the role of miR21 in vascular biology and the pathogenesis of vascular diseases.

Abstract
Nuclear factor (NF)-kappaB (NFKB1)-94ins/del is an important polymorphism that affects promoter activity of the NFKB1 gene and is potentially associated with several inflammatory diseases. We investigated the association of this polymorphism with lung injury after cardiac surgery and cardiopulmonary bypass in a prospective cohort study of 283 patients. Genotyping was performed by high resolution melting analysis; analysis indicated no association of NFKB1 with postoperative lung injury (p = 0.064). Relative risks of the del allele and the del/del genotype were 1.34 (95% CI 1.02-1.75) and 1.74 (95% CI 1.00-3.05) respectively. Logistic regression analysis (with factors including age, peripheral vascular disease and surgical duration as risk factors of lung injury after cardiac surgery with cardiopulmonary bypass) also failed to confirm that the NFKB1 genotype is influential for lung injury (p = 0.113). We conclude that, contrary to some other evidence, the NFKB1-94ins/del polymorphism is not associated with lung injury after cardiac surgery with cardiopulmonary bypass.

Abstract
Nowadays research and clinical studies of human reproductive endocrinology are generally carried out using human blood reproductive hormone assays. However the acquisition of human blood samples has some shortcomings. In search of new approaches, we paid attention to the fact that progesterone can be detected in cow's hair. Consequently we investigated whether or not steroid hormones are measurable in human hair. The results showed that the levels of steroid hormones in hair are not affected by shampoo and do not significantly vary between different segments of hair (i.e. top, middle and basal segments). The menstrual estradiol and progesterone rhythm of female hair is similar to that of female serum. The ratio of hair estradiol to serum estradiol in the female is 41.2% and that of hair progesterone to serum progesterone is 59.0%; the ratio of hair testosterone to serum testosterone in male is 116%. There are significant correlations between hair and serum steroid hormones of healthy human adult: gamma (estradiol) = 0.395 (n = 20), p < 0.05; gamma (progesterone) = 0.440 (n = 22), p < 0.025 and gamma (testosterone) = 0.395 (n = 25), p < 0.05.
