The MS prevalence was increased with aging. Prevalences of 0-5 MS components were 31.5% ,31.2% , 22.2% , 10.0% ,4.7%,0.3% respectively. It was significant difference between 2 groups that UA, ALT, AST, CHOL, LDL-ch (t value is 6. 473,4. 238,7. 406,6.810,8. 350, seperatly, P<0.01). Conclusions The prevalence of MS is high in the staffs of Guangdong. The blood pressure increasing prevalence was maximal. The other components prevalences were high too. MS tends to be a many data abnormality disease, early detection and intervention are important.
5.The Effect of Pseudolaric Acid on the Expression of VEGF in Hepatocellular Carcinoma Cells
Tianjin Medical Journal 2014;(1):10-12
Objective To investigate the effect of pseudolaric acid B(PAB) on the expression of vascular endothelial growth factor (VEGF) in human hepatoma BEL-7402 cells. Methods BEL-7402 cells were cultured with PAB (0, 0.5, 1.0, 2.0, 4.0 and 8.0μmol · L-1) for 6 h and stained with 0.4%trypan blue. The cell viability was observed and calculated under the microscope. The cell proliferation was detected by WST-8 analysis. The expression of VEGF mRNA in BEL-7402 cells was detected using RT-PCR method. The expression of VEGF protein in BEL-7402 cells was detected using Western blot assay. Results There was no significant difference in the cell proliferation of BEL-7402 cells between different PAB treat-ment groups and control group. With the increased concentration of PAB, the expressions of VEGF mRNA were significantly decreased in different PAB treatment groups (1.90±0.02,1.31±0.03,0.86±0.04,0.60±0.03 and 0.34±0.02) compared with that of control group (2.53±0.07, P<0.01). The expressions of VEGF protein were significantly decreased in different PAB treat-ment groups (2.60±0.09, 2.42±0.07, 1.85±0.05, 0.92±0.05 and 0.60±0.04) compared with that of control group (3.06±0.15, P<0.01). Conclusion PAB can inhibit the expressions of VEGF mRNA and protein in BEL-7402 cells.

China Pharmacy 2007;0(34):-
OBJECTIVE:To establish a HPLC method for the determination of gentamycin sulfate C component in medicinal albumin gel. METHODS: Samples was separated on Agilent ZORBAX Eclipse XDB-C8 at a column temperature of 26℃. The mobile phase was methanol-acetic acid-water (70∶5∶25, added with 0.02mol?L-1 sodium heptanesulfonate solution) for gradient elution at a flow rate of 1.0mL?min-1. The detection wavelength was set at 330nm. RESULTS: Baseline separation of gentamycin sulfate C component in medicinal albumin gel was achieved. The linear range of gentamycin sulfate C component was 0.26?g~6.50?g and its average recovery rate was 90.0%, RSD=0.43%, the lowest limit of detection was 0.368ng. CONCLUSION: The method was proved to be simple, accurate and reliable, and suitable for the content determination of gentamycin sulfate C component in related preparations.

Chinese Traditional and Herbal Drugs 1994;0(08):-
Objective To investigate the effects of paeoniflorin on proliferation and the protein expression of HFCL of human bone marrow stromal cells and to discuss molecular mechanism of blood enriching functions of paeoniflorin. Methods Flow cytometry and proteomics were used respectively to measure the effect of paeoniflorin on cell cycle and protein expression of HFCL. Results Paeoniflorin could promote HFCL from G_0/G_1 phase to S phase, increase proliferative index, up-regulate nine kinds of proteins, and down-regulate five kinds of proteins of HFCL. The proteins up-regulated include Ras-related nuclear protein, lamin A/C, isocitrate dehydrogenase 3 (NAD+), triosephosphate isomerase, ATP synthase, ribosomal protein P2, and chaperonin containing t-complex polypeptide 1. Conclusion Through promoting HFCL proliferation, acting on multiple protein targets, enhancing the synthesis of cytoarchitecture proteins and the expression of protein chaperonin, increasing the energy metabolism of HFCL, and suppressing the apoptosis of HFCL, paeoniflorin plays indirectly blood enriching function.
