RESUMO
OBJECTIVE: To observe the clinical efficacy of motherwort injection in the treatment of abnormal uterine bleeding-ovulatory dysfunction(AUB-O),and provide data support for broadening the clinical application range of motherwort injection.METHODS: A multicenter,randomized,prospective study was used.The patients who were diagnosed with AUB-O in Hospital of Chengdu University of Traditional Chinese Medicine in 2018 were randomly divided into the control group and the experimental group according to random numbers.There were 75 cases in the experimental group,7 cases were lost,and 68 cases were the final cases;another 75 cases were in the control group,4 cases were lost,and there were 71 cases in the end.In the control group,only the tranexamic acid was given.On the basis of this,the experimental group was given intramuscular injection of motherwort injection 2 mL/time,b.i.d.,for 3 consecutive days.The clinical TCM symptom scores,blood loss,blood routine,coagulation function,endometrial thickness and effective rate were compared between the two groups.All data were statistically analyzed using IBM SPSS 21.0.RESULTS: After treatment,the total effective rate of the experimental group was 97.06%,which was significantly better than that(84.51%)of the control group(P0.05),but on the 2nd day and the 3rd day after treatment,the difference was statistically different(P<0.05),and the cumulative amount of bleeding after 3 days of treatment was statistically different(P<0.05).The endometrial thickness of the experimental group was lower than that of the control group(P<0.01).CONCLUSION: Motherwort injection combined with basic therapy is effective in the treatment of AUB-O.
RESUMO
The research is aimed to investigate the effect of genistein (GEN) on the apoptosis in lipopolysaccharide (LPS)-activated RAW264.7 cells and explore the pharmacological mechanism of GEN anti-atherosclerosis (AS). RAW264.7 cells were activated by LPS, the level of TNF-α and IL-6 mRNA were detected by qRT-PCR, the expression of COX-2 and iNOS were detected by Western blot. RAW264.7 cells were pretreated with GEN for 2 h, and then incubated with LPS for 24 h. After that, CCK8 kit was used for the cell viability, Annexin V-FITC/PI kit for the apoptosis of cell. qRT-PCR was used to detect the level of CHOP, caspase-3 and miR-21. Western blot was used to detect the expression of CHOP and caspase-3. Results showed that LPS (1 000 ng·mL-1) increased the expression of TNF-α, IL-6, COX-2 and iNOS in RAW264.7 cells compared with that in control group. GEN inhibited the cell activity and the level of miR-21, promoted the expression of CHOP and caspase-3 in LPS-activated RAW264.7 cells in a dose-dependent manner. miR-21 up inhibited the expression of CHOP and caspase-3 in LPS-activated RAW264.7 cells and this process was reversed by GEN treatment. miR-21 down promoted the expression of CHOP and caspase-3, which were further enhanced by GEN. These results indicate that GEN promotes the apoptosis of RAW264.7 cells activated by LPS through down regulating miR-21 and activating endoplasmic reticulum (ER) stress pathway.
