Objective The purpose of this study was to investigate the effect of different level of sex steroids (?-estradiol and progesterone) on the proliferation of uterus endometrial epithelial cells. Methods Rabbit uterus endometrial epithelial cells were isolated by digestion of trypsin and centrifugation. The specificity and homogeneity of the endometrial epithelial cells cultured in media containing ?-estradiol and progesterone were determined by immunofluorescence staining of cytokeratin monoclonal antibody and the flow cytometric analysis. The different concentration of progesterone (P4) and ?-estradiol (E2) were added in media, the proliferative capability of the endometrial epithelial cells cells in vitro was determined indirectly by MTT assay. Results High purity endometrial epithelial cells (96%) were isolated using centrifugation method. The endometrial epithelial cells were examined by immunofluorescence staining. The endometrial epithelial cells were positive stained by anti-cytokeratin antibody. Immunofluorescence staining demonstrated that cytokeratin was detectable in the cytoplasm of epithelial cells. The cell growth curve showed that the proliferation of endometrial epithelial cells was not significantly changed by the treatment of E2 (100nmol/L) or P4 (100nmol/L) individually, but a combination of 100nmol/L E2 and 10nmol/L P4 could promote its proliferation greatly (P

Objective: To investigate the relationship between heart rate variability (HRV), blood pressure variability (BPV) and autonomic nerve function, blood vessel damage in patients with essential hypertension (EH) via synchronous monitoring. Methods: A total of 275 EH patients admitted to our hospital from 2011-04 to 2014-01 were enrolled. The vascular function was assessed by carotid-femoral pulse wave velocity (PWV). Based on PWV, the patients were divided into 2 groups: Normal PWV group (PWV<9m/s),n=185 and High PWV group (PWV≥9m/s),n=90. Synchronic 24h dynamic electrocardiogram (Holter) and 24h ambulatory blood pressure monitoring (ABPM) were performed in all patients. t-test, chi-square test, person liner correlation study and multi stepwise regression analysis were conducted to explore the relationship between HRV, PBV and PWV. Results: HRV and BPV in High PWV group had been changed unusually. Compared with Normal PWV group, High PWV group showed decreased standard deviation of the average of all normal-to-normal intervals in all 5-minute intervals (SDANN) (159.66±66.50) ms vs (194.36±119.29) ms and increased 24 h systolic blood pressure standard deviation (24h SSD) (14.40±3.65) mmHg vs (12.98±3.46) mmHg, all P<0.01; increased new index of night/day HR ratio (0.90±0.08) vs (0.87±0.06), P<0.01 and it had liner correlation to PWV (r=0.169, P=0.005). Multi stepwise liner regression analysis indicated that 24hSSD and HRV at low frequency (LF) portion had obvious and independent correlation to PWV (standard β value=0.352 and 0.212 respectively). Conclusion: ① EP patients were with decreased HRV (SDANN), increased BPV (24h SSD) and the higher incidence of arteriosclerosis; 24h SSD and HRV at LF portion were the most 2 important risk factors affecting PWV. ②Autonomic nerve dysfunction, vagus nerve over-excitatory were the independent risk factors for promoting the occurrence and development of arteriosclerosis in EH patients. ③Night/day HR ratio as a sensitive index for examining autonomic nerve function was independently related to hypertensive vessel damage. Synchronic monitoring of HRV and BPV is helpful to identify blood vessel damage in EH patients.
