ABSTRACT
Objective To investigate the incidence, influencing factors and intervention of gestrinone-related abnormal uterine bleeding at different dosage of gestrinone in the clinical treatment. Methods This was a multicenter, randomized, control study of 195 Chinese women with endometriosis or adenomyosis from June 2011 to November 2013. The subjects were randomized into three groups with oral administration of gestrinone, 2.5 mg dose at one time;twice a week group:67 cases with oral administration twice a week last three months;double dose first month group:67 cases with oral administration triple times a week at first month, then twice a week for two months; three times a week group: 61 cases with oral administration three times a week last three months. The improvement of the abnormal uterine bleeding, the changes in estrogen, liver function and blood coagulation were evaluated. At the same time, B-ultrasound examination evaluation were performed. Results (1) Three months later, the incidence of abnormal uterine bleeding in twice a week group was 30%(20/67), in double dose first month group and three times a week group were 7%(5/67) and 16%(10/61) respectively, there were significant difference between three groups (P0.05). The body mass index significantly increased in three group (P0.05). As for blood coagulation, there were also no significant differences between the groups (P>0.05). Conclusions Double dose of gestrinone in the first month could significantly decrease the incidence of gestrinone-related abnormal uterine bleeding. It is a more optimied dosage of gestrinone and without severe side effects. Clinical trial registration Chinese Clinical Trial Registry, registration number: ChiCTR- TRC-12002327.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the effects of a biotic elicitor fungal hyphae extract, an abiotic elicitor methyl jasmonate and their synergistic action on the accumulation of phenolic acids and tanshinones in Salvia miltiorrhiza hairy root.</p><p><b>METHOD</b>Different elicitors were added to S. miltiorrhiza hairy root, which was subcultured for 21 days, the dry weight and contents of phenolic acids and tanshinones were determined at different harvest-time.</p><p><b>RESULT</b>S. miltiorrhiza hairy root growth was significantly inhibited by all three treatments and the accumulation of cryptotanshinone and dihydrotanshinone were promoted by each elicition. As for the accumulation of phenolic acids, there were differences between fungal elicitor and methyl jasmonate treatments, they were promoted by methyl jasmonate while inhibited in a certain extent by fungal hyphae extract.</p><p><b>CONCLUSION</b>Fungal elicitor, methyl jasmonate and their synergistic action have significant influence on accumulation of components in S. miltiorrhiza hairy root, and the effect varies between phenolic acids and tanshinones. There is no correlation between production of water-soluble ingredients and fat-soluble components on the whole under three different treatments.</p>
