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.

3 mg/L was significantly worse than in those with hs-CRP≤3 mg/L (18.18%,5.45%;P=0.044,log-rank test). Higher hs-CRP concentration was an independent predictor of death or new vascular event(OR 3.609;95% CI 0.869—14.992;P=0.047).Conclusion Higher hs-CRP concentration in acute phase after ischemic stroke is an independent predictor of death or new vascular event in a year.

In this study, a rapid and sensitive analytical method was developed for the determination of 10 major compounds (procyanidin B1, catechin, procyanidin B2, rutin, isoquercitrin, kaempferol-3-O-rutinoside, astragalin, quercitrin, quercetin, and kaempferol) in Tetrastigma hemsleyanum by using ultra-performance liquid chromatography coupled with triple-quadrupole tandem mass spectrometry (UPLC-MS/MS) in multiple-reaction monitoring (MRM) mode. UPLC-MS/MS assay with negative ion mode was performed on a Waters CORTECS C18 (2.1 mm x 100 mm, 1.6 μm) with the mobile phase consisting of acetonitrile (A) and 0.1% aqueous formic acid (B) in gradient elution at a flow rate of 0.25 mL · min(-1) and the column temperature was set at 45 °C. Under the optimized chromatographic conditions, good separation for 10 target compounds were obtained including chiral isomer procyanidins B1 and B2 were completely separated within 8.5 min. Satisfactory linearity was achieved with wide linear range and fine determination coefficient (r > 0.996 6), the overall recoveries were ranged from 95.44%-110.40% with the RSD ranging from 2.37%-8.69%. It is the first report about simultaneous analysis of 10 major flavonoids components in Tetrastigma hemsleyanum by using UPLC-MS/MS method, which affords highly sensitive, specific, speedy and efficient method for quality control of Tetrastigma hemsleyanum

Curcumin has been reported to possess antitumor activity with low toxicity. However, the clinical application of curcumin has been significantly limited by its instability and poor metabolic property. In order to overcome these limitations and discover novel small molecules with potential antitumor activity, 29 curcumin mimics were synthesized, which were confirmed by 1H NMR and HR-MS, and their cytotoxic property was evaluated against five human cancer cell lines in vitro. Compounds 16, 18 and 19 exhibited good cytotoxic property, their IC50 value were even below 5 micromol x L(-1) to some cancer cell lines, 5-9 times better than curcumin.

Objective To analyze the result of treatment for acute-on-chronic liver failure patients with fast high efficiency Nucleoside and to explore the relations among inhibition to virus replication , liver failure development and immune rejection .Methods Sixty-two cases of acute-on-chronic liver failure pa-tients with HBV DNA(+) were divided into study group (treated with a kind of fast and nucleoside , n =30) and control group( n =32).HBV DNA,CD4 +T,CD8 +T, C3,C4 TBIL,PTA were observed at treat-ment 0w,2w and 4w.Results All of the study and control group patients , serum HBV DNA were positive before treated.And the levels of CD4+,CD8 +,C3,C 4,TBIL,PTA of study group were not significantly compared with control group .At treatment 2w , the rate of HBV DNA diverted negative in study group 90.0%(27/30), was significantly more then control group (9.4%, 3/32)(χ2=37.14 , P <0.01).But the CD4 +,CD8 +,C3,C4,TBIL,PTA levels were not significantly however between study and control group . At treatment 4w ,the rate of HBV DNA diverted negative in study group (96.7%, 29/30), was significant-ly more then control group(12.5%,4/32) (χ2 =40.74, P <0.01).CD4 +, CD8 +,C3,C4,TBIL,PTA levels of the study group were significantly more compared with the control group .The CD4 +level of study group (495.33 ±89.91)cells/ml, was higher significantly then control group (270.34 ±97.74)cells/ml( t=9.42, P <0.01),the CD8 +level (571.03 ±120.15 ) cells/ml, was higher significantly then control group(224.88 ±79.68)cells/ml( t =13.45, P <0.01).The C3 level of the study group (0.28 ±0.11) g/L, was lower significantly then control group ( 0.68 ±0.13 ) g/L ( t =13.13 , P <0.01 ) , the C4 level (0.12 ±0.06)g/L, was lower significantly then control group (0.23 ±0.10)g/L( t =4.92, P <0.01). The TBIL level of study group ( 653.93 ±131.02 )μmol/L, was higher significantly then control group (285.63 ±154.63)μmol/L( t =10.09, P <0.01),the PTA level (17.13 ±7.07)%, was lower signifi-cantly then control group(50.94 ±13.68)%( t =12.10, P <0.01).The death rate of the study group( 57.9%) was higher significantly compared with the control group (28.1%)(χ2 =6.39, P <0.05).Con-clusion Treatment of chronic severe hepatitis with fast and high efficiency nucleoside may arise the T cell subset level and make the immune rejection strength , as a result the liver failure maybe far away from cure .
