Panax notoginseng (PN) is one of the commonly used clinical medicines for cardiovascular diseases and possesses a variety of pharmacological effects. P. notoginseng saponins (PNS) are the most important bioactive components in PN. The purpose of this study was to explain the mechanism of PNS on molecular network level. 18 targets of the main medicinal ingredients of PNS were gained by virtual screening based on pharmacophores and data mining. A protein interaction network of PNS was constructed with 189 nodes and 721 interactions. By a graph theoretic clustering algorithm Molecular Complex Detection (MCODE), 14 modules were detected. Gene ontology (GO) enrichment analysis of the modules demonstrated that the roles of PNS played in cardiovascular disease related to multiple biological processes, which could represent the characteristics of traditional Chinese medicine (TCM) as a whole to regulate the disease. The results showed that the blood circulation and hemostasis efficacy of PN related with the biological processes such as positive regulation of cAMP metabolic and biosynthetic process, platelet activation and regulation of blood vessel size, regulation of T cell proliferation and differentiation and so on. Therefore, the module-based network analysis will be an effective method for better understanding TCM.

Aim To investigate the effects and mecha of ganoderma lucidum polysaccharides and metformin on pathological changes of thoracic aorta in diabetic ratsandthemechanisms.Methods SDratswerefed with high fat diet for 4 weeks and injected with strepto-zotocin ( 30 mg · kg-1 ) to replicate type 2 diabetic model. The diabetic rats were randomly into diabetes group, ganoderma lucidum polysaccharides group ( 600 mg·kg-1 ) ,metformin group(600 mg·kg-1 ) ,combi-nation group ( ganoderma lucidum polysaccharides 300 mg· kg-1 + metformin 300 mg · kg-1 ) and normal control group. After 12 weeksˊ treatment, the levels of fasting serum glucose, the activity of catalase(CAT), glutathione peroxidase ( GSH-Px ) , total cholesterol (TC)and triglyceride(TG) in serum were detected. Pathological changes of thoracic aorta were observed by HE staining. Immunohistochemy and Western blot were used to detect thoracic aorta VEGF protein expression. Results Combination group could lower fasting serum glucose and blood fat significantly, meanwhile the ac-tivity of CAT and GSH-Px in serum was improved. The expression of VEGF in thoracic aorta was repressed. The result of HE staining suggested that the lipid de-posits in aortic endothelium in combination group were lessthanthoseinthemodelgroup.Conclusions Ga-noderma lucidum polysaccharides combined with met-formin has an obvious prevention on pathological chan-ges of thoracic aorta in diabetic rats. The possible mechanism may be related to repressing oxidative stress of thoracic aorta, regulating the dyslipidemia, and the down regulation of the expression of VEGF in thoracic aorta.

Objective To study the effect of ganoderma lucidum polysaccharides combined with metformin on oxidative stress of type 2 diabetic rats. Methods SD rats were fed with high fat diet for 4 weeks and injected with streptozotocin (30 mg·kg-1 ) to produce type 2 diabetic model. The diabetic rats were randomly divided into diabetes model group, ganoderma lucidum polysaccharides group (600 mg·kg-1 ), metformin group (600 mg·kg-1 ), combination group (ganoderma lucidum polysaccharides 300 mg·kg-1+ metformin 300 mg·kg-1 ), After 12 weeks of treatment, the level of fasting blood glucose was determined, and the activity of superoxide dismutase ( SOD), malondialdehyde ( MDA), catalase ( CAT), glutathione peroxidase (GSH-Px), total cholesterol (TC) and triglyceride (TG) were detected. Results The levels of fasting blood glucose in the treatment groups were significantly lower than that in the diabetes model group (P<0. 01). Furthermore, fasting blood glucose in the combination group was significantly lower than that in ganoderma lucidum polysaccharides group and metformin group (P<0. 01). Compared with diabetes model group, serum TC and TG in the treatment groups were significantly lower (P<0. 05, P<0. 01). Serum TC and TG were significantly lower in the combination group than in ganoderma lucidum polysaccharides group and metformin group (P<0. 05, P<0. 01). Compared with diabetes model group, serum SOD levels in the treatment groups were significantly higher (P<0. 01). Compared with ganoderma lucidum polysaccharides group and metformin group, serum SOD levels in the combination group was significantly higher (P<0. 05). Compared with diabetes group, serum MDA levels in the treatment groups were significantly lower (P<0. 01). Serum MDA in the combination group was significantly lower than that in ganoderma lucidum polysaccharides group and metformin group ( P<0. 05). Compared with diabetes model group, serum CAT and GSH-Px in the treatment groups were significantly higher (P<0. 05, P<0. 01). Serum CAT and GSH-Px in the combination group were significantly higher than those in ganoderma lucidum polysaccharides group and metformin group (P<0. 05). Conclusion Ganoderma lucidum polysaccharides combined with metformin could effectively inhibit oxidantion stress in type 2 diabetic rats. The effect was better than ganoderma lucidum polysaccharides or metformin used alone. The possible mechanism may be related to increased activity of SOD, CAT, GSH-Px in vivo and regulation of dyslipidemia.
