This study was aimed to establish Chinese medicine efficacy concept network in order to reveal the in-ner relation between traditional Chinese medicine (TCM) and efficacy as well as to suggest the application way of efficacy concept network. Through the collation of medicine efficacy recorded in the Pharmacopoeia of the People's Republic of China (2010 Edition, Volume I), the correlation relationship between TCM efficacy concept was systematically analyzed, and the efficacy concept network was constructed in order to extract specific effica-cy sub-network based on efficacy concept network and then to discover the efficacy groups by utilizing the net-work clustering algorithm. In the Chinese medicine efficacy concept network, 422 efficacy concepts were con-structed and 21 tightly efficacy groups were discovered. Using the efficacy of promoting blood circulation as an example, the application of sub-networks was discussed. Chinese medicine efficacy concept network can be used to reflect the basic theory and clinical experiences in Chinese medicine , to systematically reveal the relationship between TCM efficacy concepts, which can be beneficial to guide the reasonable application of Chinese medicine in disease treatment .

Physical training induces beneficial adaptations,but long excessive exercise may lead to severe damage to the skeletal muscles,liver,heart,kidneys and immune functions. Over the past few decades,health scholars have been searching for natural components that can prevent or improve the damage induced by hyperkinesis. The mechanisms of organ damage induced by long overtraining include immunosuppression,metabolism disorder,hormone disturbance,oxidative damage, etc. Natural poly-saccharides have interventional effects on these injuries,possibly by improving immunity,regulating metabolism and ameliorating free radical damage.

Objective To study a improved technique by releasing the orbicularis retaining ligament in orbicularis oculi muscle supension blepharoplasty.

Objective To investigate the expression of vascular endothelial growth factor (VEGF), angiopoietin and their receptors (VEGFR and Tie2) in aging mice kidney and the possible roles in aging mice. Methods Mice were divided as follows: 4-month old group (n=6), 9-month old group (n=6), 12-month old group (n=6) and 20-month old group (n=6). Paraffin sections of the mice kidneys were stained by PAS. The density of glomerular microvascular was determined by renal perfusion with fluorescent dyes. The level of VEGF, VEGFR2 (Flk-1), Ang-1, Ang-2, Tie2 mRNA expression and protein abundance in kidney was determined by real-time PCR, immunochemistry, immunofluorescence and Western blot. Results Compared with other three groups, in the 20-manth old group, the glomerulosclerosis index (GSI) increased remarkbly (2.48±0.79 vs 0.53±0.19, 0.69±0.18, 1.50±0.70, P<0.05); the fluorescence intensity in glomeruli decreased (P<0.05). lmmunohistochemistry demonstrated that the TGF-131 level in the aging kidneys showed an increase trend in the glomerular tubulointerstitium, and especially in the glomeruli. Real-time PCR results revealed that compared with 4-month old group mice, the mRNA expression of VEGF, Flk-1, Ang-1, Ang-2, Tie2 of the other three groups decreased, the gene levels of VEGF, Flk-1, and Ang-2 fell about 90%, 50% and 80% (all P>0.05), and the gene levels of Ang-1 and Tie2 fell about 75% and 40% in 20-month-old group (all P<0.05). Western blot domonstrated that the protein abundace of VEGF, Flk-1, Ang-1, Ang-2, Tie2 also declined with aging, the protein level of VEGF, Flk-1, Ang-1, Ang-2 and Tie2 dropped by about 35%, 50%, 15%, 13% and 21% respectively in 20-month-old group as compared to 4-month-old group (all P<0.05). Expression of above 5 factors and glomerular fluorescence intensity were negatively correlated with Scr (P<0.05). Conclusions The mRNA expression and protein abundance of VEGF, Flk-1, Ang-1, Ang-2, Tie2 in mice kidneys decreases with aging. Angiogenesis regulatory factors may play important roles in aging progression of the mice kidney.

OBJECTIVETo investigate the protective effect of H2S pretreatment after cerebral schemia/reperfusion injury and its mechanisms in rats.

METHODSThe rat model of global cerebral ischemia/reperfusion injury was established by bilateral common carotid arteries occlusion combined with hemorrhagic hypotension.30 rats were randomly divided into four groups(1)sham group(n=5),in which rats received sham surgery only,with their bilateral vertebral artery and bilateral common carotid artery exposed but without ischemia treatment;(2)global cerebral ischemia/reperfusion model group(IR group,n=5),in which the global cerebral ischemia was induced by 10-min occlusion of bilateral common carotid arteries combined with hypotension;(3)H2S pretreatment group(n=15),in which H2S(12,24,48 Μmol/kg)was intraperitoneally injected before operation;(4)NaCl pretreatment group(n=5),in which the rats were intraperitoneally injected with saline 30 minutes before operation.The activities of superoxide dismutase(SOD)and the levels of malondialdeehyde(MDA)in brain were measured by spectrophotometry.Brain water content was detected.The expression of heat shock protein 70(HSP70) in the hippocampus was determined by Western blotting.

RESULTSThe SOD activities were significant increased in groups pretreated with 12Μmol/kg H2S(P=0.042),24Μmol/kg H2S(P=0.002),and 48Μmol/kg H2S(P=0.000),and the SOD activity was significantly lower in the ischemia group than in the Sham group(P=0.003).The MDA activities in the 24Μmol/kg group(P=0.026)and the 48Μmol/kg group(P=0.015)groups were significantly lower than in the IR group.The brain water content was decreased in H2S pretreatment group(24Μmol/kg and 48 Μmol/kg)compared with IR group(P=0.018,P=0.008),and it was also significantly higher in the IR group than in the sham group(P=0.009).The expression of HSP70 were decreased in H2S pretreatment group(24 Μmol/kg)compared with the IR group(P=0.000),and the expression of HSP70 were significantly higher in the IR group than in HSP70 group(P=0.000).The expression of HSP70 also significantly differed between NaCl group and HSP70 group(P=0.000).

CONCLUSIONH2S has protective effects on cerebral ischemia and reperfusion,which may be achieved by improving SOD activity,removing oxygen free radicals,inhibiting lipid peroxidation,and down-regulating the expression of HSP70 in the hippocampus.

At present, studies on traditional Chinese medicine (TCM) properties are mostly restricted to a single or two kinds of medicinal properties, but deviated from the holism of the theoretical system of TCMs. In this paper, the characteristics of pharmacological effects of different property combinations of TCMs distributing in the stomach meridian were take as the study objective. The data of properties of TCMs distributing in the stomach meridian was collected from the Pharmacopoeia of the People's Republic of China (2005). The data of pharmacological effects of TCMs distributing in the stomach meridian was collected from all of literatures recorded in Chinese Journal Full-text Database (CNKI) since 1980, Science of Chinese Materia Medica (Yan Zhenghua, People's Medical Publishing House, 2006) and Clinical Science of Chinese Materia Medica (Gao Xuemin, Zhong Gansheng, Hebei Science and Technology Publishing House, 2005). The corresponding pharmacological effects of property combinations of TCMs distributing in the stomach meridian was mined by the method of association rules. The results of the association rules were consistent with the empirical knowledge, and showed that different medicinal property combinations had respective pharmacological characteristics, including differences and similarities in pharmacological effects of different medicinal property combinations. Medicinal property combinations with identical four properties or five tastes showed similar pharmacological effects; whereas medicinal property combinations with different four properties or five tastes showed differentiated pharmacological effects. However, medicinal property combinations with different four properties or five tastes could also show similar pharmacological effects. In this study, the medicinal property theory and the pharmacological effects of TCMs were combined to reveal the main characteristics and regularity of pharmacological effects of TCMs distributing in the stomach meridian and provide a new way of thinking and method for revealing the mechanism action of TCMs distributing in the stomach meridian and discovering the pharmacological effects of TCMs distributing in the stomach meridian.
