Objective:To investigate effect of curcumin on serum gelatinases level in patients with unstable angina pectoris (UAP). Methods:A total of 80 UAP patients admitted from January 2010 to September 2010 were enrolled and randomly divided into curcumin treatment group (n=40) and routine treatment control group (n=40). Serum levels of gelatinases [contain matrix metalloproteinase (MMP)-2 and -9] of the two groups were measured before and 30d after treatment.Results: Compared with before treatment , after treatment, serum levels of gelatinases significantly decreased [MMP-2:(52.64±6.77)ng/ml vs.(32.65±1.67)ng/ml,MMP-9:(56.75±7.34)ng/ml vs.(35±1.88)ng/ml]in curcumin treatment group (P<0.01), and they were significantly lower than those of routine treatment control group[MMP-2:(32.65±1.67)ng/ml vs.(37.78±2.76)ng/ml,MMP9:(35±1.88)ng/ml vs.(40.23±1.95)ng/ml]],P<0.05. Conclusion:Curcumin could decrease serum levels of gelatinases in patients with unstable angina pectoris, and possesses effect stabilizing coronary artery plaque.

Objective To observe the levels of matrix metalloproteinases-9 (MMP-9) and tissue factor (TF) as well as blood lipid in patients with acute coronary syndrome (ACS) ,and to study the effect of Fluvastatin on levels of serum MMP- 9 and plasma TF. Methods 40 patients with ACS were selected (including 20 patients with AMI and 20 patients with UAP) ,20 stable angina patients (SAP) and 13 patients without coronary heart dis-ease as control group. 40 patients with ACS were randomly assigned to the Fluvastatin group (n = 20) and the rou-tine group (n = 20) in this study. The MMP - 9 and TF were detected on admission and after 2 weeks treatment. Re-suits The levels of MMP-9 and TF were significantly higher in ACS group than that of SAP and control group (P < 0.001 ,P < 0.05) ,which were elevated in AMI group compared with that of UAP group (P < 0.05). The levels of cholesterol (TC) ,low density Lipoprotein (LDL - C) ,MMP- 9,TF decreased significantly at two weeks after treat-ment in fluvastatin group (P < 0.05), but no significant changes were observed in the routine group (P > 0.05). The change of MMP 9, TF and blood lipid was not related in fluvastatin group (P > 0.05). Conclusion Serum MMP-9 and plasma TF in ACS patients are significantly elevated and fluvastatin decreases the levels of MMP-9 and TF after two weeks treatment,so it may be benefit to atheroaclerotic plaque stabilization and prohihit thrombosis for-marion, and this is not related to regulation of blood lipid.

Mesoporous silica SBA-15 with a small organic molecular (1,8-Naphthalimide) was synthesized and used as matrix for MALDI-TOF-MS ( Matrix-assisted laser desorption/ionization time of flight mass spectrometry) analysis. A modified SBA-15 matrix, SBA-15-NA (1,8-Naphthalimide) was synthesized by covalently attaching SBA-15 to an 1 , 8-naphthalimide formed by 1 , 8-naphthalic anhydride and 3-( trimethoxysilyl) propylamine. The mass spectra obtained with SBA-15-NA exhibited less background interference ions, higher desorption/ionization efficiency, and higher peak intensity. The matrix was initially prepared in methanol and mixed with analyte at a 1∶1 volume ratio in vial. The solution of mixture was at a 10∶1 concentration ratio of matrix/analyte on a stainless steel target and allowed to air dry. The method was used to analyze various types of low molecular weight ( less than 500 ) chemical compounds such as monosaccharides, amino acids, phytohormones, drugs. Under the optimal conditions, it gave low detection limit of 1×10-9 g/L (Leucine, S/N=5) and good reproducibility (≤30%). The modified mesoporous silica materials have been employed in the urinary study for direct detection of metabolites.

Eight 1,6-O,O-diacetylbritannilactone (OABL) derivatives (compounds 1-8) were synthesized by esterification or reduction of 1-O-diacetylbritannilactone (ABL) isolated from Inula japonica.All derivatives were evaluated for their anti-inflammation activities through the determination of inhibition of nitric oxide (NO) production in lipopolysaccharide (LPS)-induced macrophages.As results,compounds 5-8 (IC50 ＜ 2 μmol/L) exhibited more potent inhibition of NO production activities than the lead compound OABL.

Objective To explore the role of pregabalin on the expression of c-fos in spinal dorsal horn of the rat with neuropathic pain.Methods Thirty Wister rats (male) were divided into shamoperated group,model group and pregabalin group,with 10 cases in each group.The effect of the pregabalin on the heat pain threshold and expression of c-fos in spinal dorsal horn of the rat with neuropathic pain were observed.Results The heat pain threshold in model group at 3rd,4th,5th,6th,7th,10th and 14th day after operation was significantly lower than that in sham-operated group and pregabalin group at same time (P ＜ 0.05).The heat pain threshold in pregabalin group was lower than that in sham-operated group from 2nd day after operation,but there was no significant difference (P ＞0.05).At the 14th day after operation,the number of Fos-like-immunoreactivity (FLI) positive cells in sham-operated group,model group and pregabalin group was (16.4 ± 0.6),(66.7 ± 3.3) and (22.8 ± 1.5)cases,and the number of FLI positive cells in model group was significantly higher than that in shamoperated group and pregabalin group (P ＜ 0.05).Conclusions Pregabalin has analgesic activity on rat with neuropathic pain.Pregabalin activates spinal cord glial cells raisedby the injured peripheral nerve and infection,and also reduces the noxious stimulation of afferent pain to spinal dorsal horn neurons.

Objective: To study changes of serum levels of hepatocyte growth factor (HGF), soluble intercellular adhesion molecule-1 (sICAM-1) in patients with essential hypertension (EH) and their significance. Methods: A total of 59 EH patients were selected, including 20 cases with EH stage 1 (EH stage 1 group), 19 cases with EH stage 2 (EH stage 2 group) and 20 cases with EH stage 3 (EH stage 3 group). Another 30 healthy subjects were regard as normal control group. Double antibody enzyme-linked immunosorbent sandwich assay was used to measure concentrations of HGF and sICAM-1 in all groups, and then the results were compared and analyzed. Results: Compared with normal control group, there were significant increase in serum levels of HGF [(641.65±142.90) pg/ml vs. (998.15±241.38) pg/ml] and sICAM-1 [(161.70±32.36) ng/ml vs. (327.17±31.28) ng/ml] in EH patients (P<0.01 both), and it’s more significant as blood pressure increased (P<0.01). HGF concentration was positively correlated with sICAM-1 concentration (r=0.317, P<0.01). Conclusion: HGF and sICAM-1 may participate in pathogenesis of hypertension, indicating that HGF plays an important role in restore of impaired endothelial cells in hypertension.
