Experimental autoimmune encephalomyelitis (EAE) is a T cell-mediated autoimmune disease of the CNS. Metformin is the most widely used drug for diabetes and mediates its action via activating AMP-activated protein kinase (AMPK). We provide evidence that metformin attenuates the induction of EAE by restricting the infiltration of mononuclear cells into the CNS, down-regulating the expression of proinflammatory cytokines (IFN-gamma, TNF-alpha, IL-6, IL-17, and inducible NO synthase (iNOS)), cell adhesion molecules, matrix metalloproteinase 9, and chemokine (RANTES). Furthermore, the AMPK activity and lipids alterations (total phospholipids and in free fatty acids) were restored by metformin treatment in the CNS of treated EAE animals, suggesting the possible involvement of AMPK. Metformin activated AMPK in macrophages and thereby inhibited biosynthesis of phospholipids as well as neutral lipids and also down-regulated the expression of endotoxin (LPS)-induced proinflammatory cytokines and their mediators (iNOS and cyclooxygenase 2). It also attenuated IFN-gamma and IL-17-induced iNOS and cyclooxygenase 2 expression in RAW267.4 cells, further supporting its anti-inflammatory property. Metformin inhibited T cell-mediated immune responses including Ag-specific recall responses and production of Th1 or Th17 cytokines, while it induced the generation of IL-10 in spleen cells of treated EAE animals. Altogether these findings reveal that metformin may have a possible therapeutic value for the treatment of multiple sclerosis and other inflammatory diseases.

Objective To observe the effect and clinical efficacy of Qilin Pill (QP) combined met- formin on matrix metalloproteinase 9 (MMP-9), vascular endothelial growth factor (VEGF) , hepatocyte growth factor (HGF) , sex hormones, insulin resistance (IR) related indicators in polycystic ovaries induced infertility women. Methods Totally 58 polycystic ovarian syndrome (PCOS) complicated infertility patients admitted to authors' hospital were serial numbered according to visit sequence. The odd num- bers were recruited as the control group, and the even numbers were recruited as the test group, 29 ca- ses in each group. Patients in the control group took Metformin Hydrochloride Tablets, while those in the test group additionally took QP. All patients received 3 months of treatment. After treatment serum con- tents of VEGF, MMP-9, HGF, sex hormones, IR related indicators, and clinical efficacy were detected in all patients. Results (1) There was no statistical difference in serum contents of MMP-9, VEGF, HGF, sex hormones [luteinizing hormone (LH) , testosterone (T) ] , or serum levels of fasting serum insulin (FINS) and insulin sensitive index (IS]) related indicators between the two groups before treatment (P> 0. 05) ; (2) Compared with before treatment in the same group, there was statistical difference in serum contents of MMP-9, VEGF, HGF, and levels of LH, T, FINS, ISI in the two groups after treatment (P < 0. 05) ; (3) Compared with the control group, patients' serum contents of MMP-9, VEGF, HGF,and levels of LH, T, FINS, ISI were lower in the test group after treatment (P <0. 05) ; (4) After treatment the ovulation rate (93.2%) and the pregnancy rate (48.3%) were higher in the test group than in the control group (P <0.05). Conclusion QP combined metformin could significantly reduce serum levels of LH. FINS and T, contents of VEGF, HGF, and MMP-9, improve IR, and elevate the ovulation rate and the pregnancy rate in PCOS induced infertility patients.
