RESUMEN
Objective: To observe the clinical efficacy of Wumeiwan combined with Bazhentang in the treatment of obesity type 2 diabetes with Qi and Yin deficiencies, phlegm and stasis. Method: Totally 60 patients with type 2 diabetes mellitus were randomly divided into observation group and control group, with 30 cases in each group. Observation group was given Wumeiwan combined with modified Bazhentang in addition to Western medicine (metformin hydrochloride). The control group was treated with traditional Western medicine (metformin hydrochloride). The course of treatment is eight weeks. Fasting blood sugar (FPG),2 hPG (2 hPG),glycosylated hemoglobin (HbA1c),total cholesterol (TC),triglycerin (TG),body mass index (BMI),safety indicators (three major routine,liver and kidney functions) and clinical symptoms before and after treatment between two groups were compared. The clinical efficacy of two groups was evaluated. Result: The observation group had an effective rate of 93.3% (28/30),which was significantly higher than 73.3% (22/30) of the control group,with statistically significant differences (PPPPConclusion: Modified Wumeiwan combined with Bazhentang is safe and effective in treating patients with type 2 diabetes mellitus with Qi and Yin deficiencies, phlegm and stasis,and can reduce blood sugar,blood lipid,BMI level and relieve clinical symptoms of patients, and so worth promotion.
RESUMEN
Previous studies have shown that STAT3 plays a vital role in the genesis and progression of cancer. In this study, we investigated the relationship between the JAK2/STAT3 signalling pathway and germacrone-induced apoptosis in HepG2 cells. HepG2 cells were incubated with germacrone for 24 h, the protein expression of p-STAT3, STAT3, p-JAK2 and JAK2 was detected by Western Blotting, and RT-PCR was used to determine the expression of STAT3, p53, Bcl-2 and Bax at transcriptional levels. Besides that, HepG2 cells were pre-treated with AG490 or IL-6 for 2 h, and then incubated with germacrone for 24 h. The expression of p-JAK2, JAK2, p-STAT3, STAT3, p53, Bax and Bcl-2 was detected by Western blotting. The activity of HepG2 cells was tested by MTT assay. The apoptosis of HepG2 cells and levels of reactive oxygen species (ROS) were flow cytometrically measured. The results showed that germacrone exposure decreased p-STAT3 and p-JAK2 and regulated expression of p53 and Bcl-2 family members at the same time. Moreover, IL-6 enhanced the activation of the JAK2/STAT3 signalling pathway and therefore attenuated the germacrone-induced apoptosis. Suppression of JAK2/STAT3 signalling pathway by AG490, an inhibitor of JAK2, resulted in apoptosis and an increase in ROS in response to germacrone exposure. We therefore conclude that germacrone induces apoptosis through the JAK2/STAT3 signalling pathway.
