China Pharmacy 2007;0(36):-
OBJECTIVE:To evaluate the curative efficacy of Chinese medicine vs. western medicine in the treatment of diabetes. METHODS:The randomized controlled trials(RCTs) comparing western medicine with traditional Chinese medicine alone or combination of Chinese medicine and western medicine in the treatment of diabetes were systematically evaluated. Meta-analysis of the cited trials was performed by evidence-based medicine method with Revman 4.2 software for statistical analysis. RESULTS:A total of 14 RCTs met our inclusion criteria. Meta-analysis showed that there was no significant difference between traditional Chinese medicine and western medicine in clinical efficacy in the treatment of diabetes; however,the diabetic patients treated with integrated Chinese medicine and western medicine showed much better efficacy than those treated with western medicine alone. CONCLUSION:Treatment of diabetes with traditional Chinese medicine plus western medicine has more advantages; however,this conclusion remains to be confirmed further by studies of high quality given the low quality in test methodology.

BACKGROUND:Many studies have demonstrated that in order to achieve the endothelialization of the polymer materials, surface loading of bioactive factors is an important means and the introduction of human endothelial cells on the surface of the polymer materials wil contribute to increase the biocompatibility of materials. OBJECTIVE:To synthesize the polyethylene glycol hydrogel packaging vascular endothelial growth factor, basic fibroblast growth factor and endothelial progenitor cells, and to observe the sustained release of growth factors and culture status of endothelial progenitor cells. METHODS:The polyethylene glycol-modified hydrogel containing arginine-glycine-aspartic acid peptide was synthesized, and then, rat endothelial progenitor cells, basic fibroblast growth factor, vascular endothelial growth factor, matrix metal oproteinases were successively added. The hydrogel were immersed in PBS, and ELISA was used to test the levels of growth factors in supernatants every 12 hours. Matrix metal oproteinases-2 (100, 1 000 ng) and matrix metal oproteinases-9 (100, 1 000 ng) at different mass were added into the PBS containing hydrogel after 72 hours. ELISA was also used to test the levels of growth factors in supernatants every 12 hours. The hydrogel encapsulating endothelial progenitor cells was cultured in a culture medium for 5 days, and the number of survival cells was counted by a flow cytometer after digestion. RESULTS AND CONCLUSION:Within 12-72 hours, the release percentage of basic fibroblast growth factor and vascular endothelial growth factor remained at about 41%. After 72 hours, the release percentage of both growth factors was found to grow steadily when matrix metal oproteinases-2 (100, 1000 ng) and matrix metal oproteinases-9 (100, 1 000 ng) at different mass were added, which reached 95%. The release percentage was increased with the increasing mass of matrix metal oproteinases. After 5 days of culture, 88.17%cells stil survived in the hydrogel. These findings indicate that sel-assembly polyethylene glycol-modified hydrogel can realize the control ed release of basic fibroblast growth factor and vascular endothelial growth factor, and it can also support the proliferative growth of endothelial progenitor cells.

Parkinson's disease (PD) is a common neurodegenerative disorder associated with aging. Great progresses have been made toward understanding the pathogenesis over the past decades. It seems that both genetic factors and environmental factors contribute to PD, while the precise pathogenesis still remains unknown. Recently, increasing evidence has suggested that autophagy dysregulation is closely related to PD. Dysregulation of the autophagic pathways has been observed in the brains of PD patients or in animal models of PD, and a number of PD-associated proteins, such as a-synuclein, Parkin and PINK1, were found to involve in autophagy, suggesting a link between autophagy and pathogenesis of PD. In this review, we summarized the role of PD-associated proteins in autophagy pathways. In addition, we described the efficacy of autophagy-modulating compounds in PD models and discussed promising strategies for PD therapy.
