Objective:To understand the level of progesterone (P4) in different quality of buffalo cumulus oocyte complexes (COCs) and further to evaluate the effect of exogenous P4 supplementation on maturation and subsequent developmental ability of poor quality brilliant cresyl blue (BCB-)***: Progesterone secreted by different quality of buffalo oocytes was estimated by enzyme linked immunosorbent assay and the concentration differences were translated into P4 doses to be incorporated in the maturation medium of BCB-ve COCs followed by expression analysis of genes involved in the cumulus expansion, extracellular matrix disintegration and progesterone receptor signalling. In addition, the study also evaluated the effect of exogenous P4 on sperm-cumulus interaction. Results: More than 10-fold up-regulated expression of progesterone receptor in P4 supplemented oocytes signified that P4 might be acting predominantly through this receptor. Also, exogenous P4 supplementation had significant effect on transcatheter arterial chemoembolization protease regulated by P4-progesterone receptor pathway which in turn had an important role in extracellular matrix disintegration. On the contrary, cumulus expansion genesHAS2,TNFAIP6,AREG were not altered upon P4 supplementation. Also, it was observed that P4 addition did facilitate passage of significantly more number of spermatozoa through P4 treated cumulus cells. Further, incorporation of different doses of P4 did not improve significantly the cleavage and blastocyst rates of BCB-ve ***: Different qualities of buffalo COCs secrete substantially diverse levels of P4, and its supplementation has a role in oocyte maturation via modulation of cumulus characteristics but perhaps not fertilization.

A Preliminary Study of TCM Stage-Oriented Treatment of Atherosclerosis

引用

Journal of Traditional Chinese Medicine 2009年第3期29卷 201-204页

作者：王筠张军平王新中 Postgraduate student of Grade 2003 Tianjin College of Traditional Chinese Medicine scientific Research Department of Tianjin College of Traditional Chinese Medicine

Based on the combination of the traditional TCM theory and the idea and results of modern medical research on atherosclerosis (AS), the authors understand the pathology of AS in three stages and have studied the stage-oriented differential treatment of AS, namely, 1) the formation stage of AS plaque treated with the principle of regulating the liver, nourishing the kidneys and strengthening the spleen; 2) the stable stage of AS plaque treated with the principle of clearing away heat and toxic materials; and 3) the breaking stage of AS plaque treated with the principle of promoting blood circulation and removing blood stasis. We propose that the TCM treatment of AS should be based on the achievements of modern medical research, utilizing stage-oriented treatment according to the different stages of the formation and development of AS plaque, so as to improve the therapeutic effects.

作者： Yuanjing Zhang Pingcang Zhang Yasong Li Chao Li Institute of Hydrogeology and Environmental Geology Chinese Academy of Geological Sciences Yangtze River scientific Research Institute Weiqiao Management office in Shijin Irrigation District of Hebei Province

[ Objective] The study aimed to discuss the anti-erosion characteristics of different soils under artificial rainfall conditions. [ Method] Through artificial rainfall experiments, the characteristics of surface runoff and sediment yield of loess, black soil, purple soil and red soil wee cont- rastively studied under the same experimental conditions. [ Resultl Under the same conditions, red soil had the best anti-erosion ability, fallowed by purple soil, black soil and loess. In practice, soil and water conservation measures should be adopted according to erosion characters of different soils. [ Conclusion] The research could provide scientific references for the establishment of soil and water conservation measures in soil erosion ar- eas of China.
