Objective: This study was designed to assess the protective effects of high-dose aprotinin on isolated rat hearts from ischemia-reperfusion injury. Method: The study consisted of two groups of rats. An isolated rat working heart model was established. Group A (n=16), received cardioplegia with high-dose aprotinin. Group B (n=16), received same cardioplegia only. The rat hearts were perfused for 30 minutes, then arrested for 40 minutes and reperfused for 30 minutes. The hemodynamic parameters, myocardial creatine kinase (CK) and myocardial ultrastructure were measured before ischemia and during reperfusion. Results: Recovery of cardial function, coronary flow and myocardial ultrastructure in group A was significantly better. CK level was lower in group A. Conclusion: High-dose aprotinin (1×106 KIU/L) may reduce myocardial ischemic and reperfusion injuries.

AIM:To study the effect of fractalkine(CX3CL1,Fkn) on the expression and secretion of matrix metalloproteinase-2(MMP-2) in cultured human monocyte line U937 cells.METHODS:The cultured U937 cells were incubated with recombinant human Fkn,the supernatant of human renal mesangial cells(HRMC) and Fkn neutralizing antibodies for 24 h.The mRNA expression of MMP-2 was analyzed by RT-PCR.The production of MMP-2 in the supernatant was analyzed by gelatin zymography.RESULTS:The level of MMP-2 mRNA and protein in the cells incubated with recombinant human Fkn decreased compared to control group.Similarly,the level of MMP-2 mRNA in the cells incubated with the supernatant of HRMC reduced compared to control group.However,the level of MMP-2 mRNA and protein in the cells incubated with the supernatant of HRMC adding Fkn neutralizing antibodies increased compared to that incubated with the supernatant of HRMC.CONCLUSION:Fkn inhibits the expression and secretion of MMP-2 in cultured U937 cells.HRMC might mediate the expression and secretion of MMP-2 in U937 cells through Fkn.

[Objective] To observe NGF on cultured human retinal vascular endothelial cells (HRCEC) proliferation. [Methods] The MTT assay was used to analyze the impact of culture HRCEC on different factors (NGF concentration groups, NGF + K252a concentration groups, bFGF group, bFGF + K252a groups, the normal culture medium groups) in normal and hypoxic condition. [Results] With the increase of NGF concentration (20,50,100 ng/mL), HRCEC significantly increased (normal condition: 0.254±0.033,0.696±0.029, 1.136±0.051; hypoxic condition: 0.422±0.036, 0.798±0.044, 1.376±0.052, P< 0.05). Compared NGF + K252a group with the same concentration of NGF (100 ng/ml) group, HRCEC reduced (P<0.05), with increasing the concentration of K252a (50,100,200 nmol/L), the trend of HRCEC decreasing is become more significant (normal condition:0.864±0.067, 0.496±0.025, 0.202±0.078; hypoxic condition:K252a 1.042±0.047,0.700±0.065, 0.401±0.078, P<0.05). [Conclusion] NGF can promote the proliferation of HRCEC, the effect could be specifically blocked by TrkA inhibitor K252a.

A novel method for analysis of three active components curcumin, demethoxycurcumin and bisdemethoxycurcumin in Curcuma longa L. was developed by HPLC coupled with electrochemical detection. Three curcuminoids were well separated on a C18 column and detected with high sensitivity. A mobile phase containing acetonitrile and 10 mM Na2HPO4-H3PO4 (pH 5.0) (50:50, v/v) was used. Good linearity was obtained in the range of 0.208-41.6, 0.197-39.4, and 0.227-114μM for curcumin, demethoxycurcumin and bisdemethoxycurcumin respectively. The limit of detection reached up to 10 ? 8 M, which was lower than that by UV detection. The relative standard deviations (RSDs) ranged from 1.06%to 1.88%for intra-day precision and from 4.30%to 5.79%for inter-day precision, respectively. The proposed method has been applied in real herb sample and recoveries ranging from 86.3%to 111%were obtained.

Objective To evaluate the clinical significance of simultaneous transurethral resection (TUR) of a bladder tumor and the prostate in the treatment of non-muscle invasive bladder cancer with benign prostatic hyperplasia (BPH).Methods Patients were divided into two groups.Group A contained 46 male patients who accepted TUR for the treatment of both bladder cancer and benign prostatic hyperplasia.Group B contained 69 male patients who accepted TURBt only.Clinical data were retrospectively collected and analyzed to compare clinical outcomes and safety in these two groups.Results The bladder cancer recurrence rates in group A and B were 50.0% and 50.7%,the average recurrence free time was 20 and 18 months,and the progression rates were 6.5% and 7.2%,respectively.There were no significant differences between the two groups for either average recurrence free time or progression rates (P > 0.05).Recurrences in the prostatic urethra were found in two cases in group A and one case in group B and all three cases were in T1 G3.Conclusions Simultaneous TUR for bladder tumor and the prostate can be safely and effectively performed in terms of oncologica] control in patients who have non-muscle invasive and low grade bladder tumors ( T1G1 - G2 ) with lower urinary tract obstruction caused by BPH.But this procedure should be cautiously performed on patients with T1 G3 bladder tumors.
