The levels of CORT, ACTH and CRH in serum were detected by ELISA, and the mRNA expressions of GR, MR, CRH in hypothalamus and GR, MR in hippocampus were detected by RT-PCR.Results:The levels of serum CORT and ACTH in SHR rats were significantly lower than those in WKY rats (P < 0.01), and the levels of serum CRH were significantly higher than those in WKY rats (P < 0.01). GR and MR mRNA expression levels in hypothalamus and hippocampus were significantly higher than those in WKY rats (P < 0.01), while CRH mRNA expression in hypothalamus was significantly lower than that in WKY rats (P < 0.01).Conclusion:The HPA axis of SHR rats showed hyporesponsiveness, which may be related to CRH priming disorder and high expression of GR and MR mRNA in hypothalamus and hippocampus.展开更多

METHODS: The databases of MEDLINE (1950-2012), EMbase (1980-2012), China biology medicine (CBM) (1994-2012), China national knowledge infrastructure (CNKI) (1989-2012), Weipu (VIP) (1995-2012) and Wanfang (1989-2012) were searched and we performed manual searches for conference proceedings to select randomized controlled trials (RCTs) on Tianmagouteng decoction for the treatment of primary hypertension with liver Yang hyperactivity syndrome. Studies were enrolled according to the study-selecting criteria. The methodological quality was evaluated, data were extracted and meta-analyses were conducted with RevMan 4.2 software. RESULTS: Nine RCTs were selected involving 784 patients with no significant difference in decrease in systolic blood pressure (SBP) [OR=1.02, 95% CI (-0.24, 2.29), P=0.10] and diastolic blood pressure(DBP) [OR=0.56, 95% CI (-0.10,1.23), P=0.11] between the Tianmagouteng group and the control group. While there was a significantly larger increase in serum superoxide dismutase (SOD)[OR= 6.26, 95% CI (1.27,11.66), P=0. 01] in the Tianma-gouteng group than that in the control group CONCLUSION: Tianmagouteng decoction can decrease both systolic and diastolic blood pressure and greatly increase serum SOD. Due to poor quality of included studies, the efficacy needs to be further assessed.展开更多
