The informatization of traditional Chinese medicine resources is the basis of modern medicine. With a spatial attribute traditional Chinese medicine resources could be carried out for in-depth spatial analysis, data mining and traditional Chinese medicine resources regional industrial layout. In this paper, we took the data of Glycyrrhiza uralensis in the third national Chinese medicine resources survey as the experimental data, described the principles and structure of traditional Chinese medicine resources spatial information database. We also described the establishment of analysis model with the help of this spatial database.

Objective To establish the HPLC determination method of chlorogenic acid for developing the quality standard of Yinqiao Jiedu Oral Liquid.Methods HPLC method was performed on an E.Merck LiChrospher 100RP-18 column(250 mm? 4 mm,5 ? m).The mobile phase consisted of acetonitrle and o.4 % phosphoric acid(10:100).The flow rate was 1.0 mL/min,column temperature was 30 ℃,and the detection wavelength was 327 nm.Results Chlorogenic acid was linear at the range of 0.12～ 0.63 ? g(r=0.999 6),the average recovery was 96.68 %,and RSD was 1.56 % .Conclusion This method is accurate,reliable,reproducible,and can provide evidence for the quality control of Yinqiao Jiedu Oral Liquid.

Objective: To discuss the way of early nutritional support in the patients after the liver transplantation. Methods: The nutritional support was used in 28 patients who had suffered the orthopetic liver transplantation (OLT).Parenteral nutrition was started as soon as possible after the operation. On the fourth day after the operation, enteral nutrition was also used. Results: 5 patients died from the postoperative complications. 23 patients survived and had been in better nutrition. Conclusion: The early nutrition support can play an important role in the patients recovery after OLT. EN should be administrated immediately when the gut functions.

The feasibility of using cord blood mesenchymal stem/progenitor cells (CB-MSPCs) to regenerate cardiomyocytes and the optimal inducing conditions were investigated. The CB mononuclear cells were cultured in low serum DMEM medium to produce an adherent layer. After expansion, the adherent cells were added into cardiomyocyte inducing medium supplemented with 5-azacytidine. Cardiogenic specific contractile protein troponin T staining was performed to identify the cardiomyocyte-like cells. The results showed that the frequency of CB-MSPCs clones in CB mononuclear cells was 0.5 x 10(-6) and about 1.3 x 10(7)-fold expansion was achieved within 20 sub-cultivation. After cardiogenic induction, 70% CB-MSPCs was differentiated into cardiomyocyte-like cells. It was indicated that low serum culture could expand CB-MSPCs extensively and the expanded CB-MSPCs could be induced to differentiate into cardiomyocyte-like cells in high efficiency.

OBJECTIVE:To study the chemical constituents of Sedum lineare. METHODS:Silica gel column chromatogra-phy,TLC and crystallization were adopted to isolate the chemical constituents of S. lineare. And chemical structures were analyzed and identified based on physicochemical properties and spectral data of compounds. RESULTS:A total of 6 sterols and 2 triterpe-noids were isolated from petroleum ether fraction of S. lineare,which were identified as stigmaster-5-ene-3β-ol-7-one(1),stigmas-ter-5-ene-3β,7α-diol(2),daucosterol(3),daucosterol palmitate(4),β-sitosterol(5),stigmaster-7-ene-3β-ol(6),δ-amyrin(7),andδ-amyrone(8)respectively. CONCLUSIONS:Compounds 3,4 and 7 are isolated from S. lineare for the first time,and compound 4 is isolated from genus S.lineare for the first time. The study has laid certain foundation for the quality evaluation of S. lineare.

Tumor cells can metabolize glucose through glycolysis to intermediates for biomacromolecule synthesis by inhibiting the activity of the pyruvate dehydrogenase complex (PDC) in mitochondria. In this process, pyruvate dehydrogenase kinases (PDKs) play a key role. The inhibition of the activity of PDKs can effectively block this metabolic pathway, activate mitochondrial oxidative metabolism, and induce tumor cell apoptosis. PDK inhibitors have become a research hotspot in medicinal chemistry, and novel structures targeting classical binding sites have been synthesized. In this paper, recent research progress on PDK inhibitors is reviewed to provide information on these latest entities and to explore their clinical applicability.

ObjectiveTo observe the effects of XinShu parenteral solution (XSPS) on the activation of platelet, the activity of fibrinolysis system after intima denudation of rabbits.Methods20 male Japanese white rabbits (2.5±0.5)kg were randomly divided into the control group and XSPS group .The celiac arterial endothelium of all rabbits were denuded with balloon. Before the operation and 3d, 7d, after balloon denudation, vein blood samples were obtained from each group rabbits for measurement of α granule membrane protein of platelets(GMP-140), tissue-type plasminogen activator(t-PA) and plasminogen activator inhibitor-type Ⅰ(PAI-1).ResultsPlasma GMP-140 and PAI-1 activity obviously elevated after balloon injury, and there was a little elevation in plasma t-PA activity in control group. Activity of plasma GMP-140 in XSPS group remained bottom level after balloon injury, and there was a significant increase in plasma t-PA activity and a marked reduce in PAI-1 activity in XSPS group. There was a notable difference between group B and group C (P<0.05). ConclusionXSPS obviously inhibits platelet activation, and improves fibrinolysis activity after balloon injury.
