CdSe/ZnSquantumdots(QDs)werepreparedandcovalentlylinkedtoanti-katacalcinmonoclonal antibodies. After modification, the QDs' maximum emission wavelength was shifted to 625 nm from 620 nm while maintaining the spectral properties. Then the QDs labeled lateral flow strip and corresponding fluorescence measuring instrument were designed and fabricated. To reduce the cost of strip by reducing the amounts of monoclonal antibodies, appropriate amounts of QDs labeled monoclonal antibodies were sprayed on the conjugation pad, with just one test line on the strip but without the control line. Parameters of the strip were optimized by measuring the signal to noise ratio. By using the strip and fluorescence measuring instrument, procalcitonin (PCT) could be detected in 20 min, and the quantitative detection range was 0. 2-100 μg/L with sensitivity of 0. 1 μg/L. A total of 22 blood samples were measured by both our method and the commercial instrument used in the hoptital. The results were consistent for their Pearson correlation coefficient (0. 9995) and Kolmogorov-Smirnov test (Sig=1. 0). The rapid quantitative detection method for PCT is of great importance to quantitative detection of bacterial infection and rational usage of antibiotics clinically.

Objective To study the inhibitory effects of Probucol on the expressions of serum promatrix metalloproteinase-2(pro-MMP-2) and matrix metalloproteinase-2(MMP-2) in patients with coronary heart disease(CHD).Methods The levels of serum Pro-MMP-2 and MMP-2 were detected by zymograph and total cholesterol(TC),triglyceride(TG),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C)were measured by enzyme method in 30 CHD patients before and after treatment with Probucol.Results After treatment of Probucol,the expression levels of pro-MMP-2,MMP-2,TC and LDL-C in serum were decreased than those before treatment,respectively;there were obvious differences of various indexes mentioned above between before and after treatment(P0.05).Conclusion Probucol can inhibit the expressions of pro-MMP-2 and MMP-2 in serum as same as TC and LDL-C.Probucol,as one of TIMPs,may be applied to stabilize plaque..

Objective To investigate the effects of trimetazidine on the oxidative stress in maintenance he-modialysis (MHD) patients. Methods Eighty-six MHD patients and 30 healthy volunteers were recruited in the study. The activity of glutathione peroxidase (GSHPx) was measured by colorimetry and superoxide dismutase (SOD) in serum was measured by hydroxylamine method. The levels of serum malondialdehyde (MDA) were meas-ured by thiobarbituric acid reaction. Serum advanced oxidation protein products (AOPP) levels were measured by enzyme-linked immunosorbent assay (ELISA). All MHD patients were randomly divided into two groups, treatment group (n = 46) and control group (n = 40), who had undergone hemodialysis for at least three months before the study and were in a stable clinic status without signs of infection or disease activity. In the treatment group,20 mg of trimetazidine was taken orally three times each day for twenty-four weeks, when the parameters for oxidative stress were studied. The levels of GSHPx. SOD, MDA and AOPP in serum were measured before and after the treat-ment. Results At the initiation of the investigation, the serum levels of GSHPx [(584.37±215.70) μmol/L, (580.87±309.12) μmol/L vs (769.06±302.46) μmol/L] and SOD [(347.87±82.09) kU/L, (348.16±75.33) kU/L vs (428.34±15.23)kU/L] in the M HD patients were significantly lower than those in the normal eontrol group (P < 0.01), whereas the content of MDA [(4.94±1.32) nmol/L, (4.97±1.61) nmol/L vs (3.56±0.46)nmol/L] and AOPP [(120.95±59.24) μg/L,(121.76±69.12) μg/L vs (47.69±20.15) μg/L] in MHD patients was higher than those in the control group( P < 0.05 and P <0.01, respectively). After treatment for twelve weeks, the scores of GSHPx and SOD were significantly increased in the treatment group compared to that before treatment (P <0.01). However, the contents of the MDA and AOPP decreased. There were significant differences in the levels of GSHPx, SOD,MDA and AOPP between the two groups of MHD patients after the treatment with trim-etazidine. Conclusions Trimetazidine in maintenance hemodialysis patients appears to be associated with an im-provement of oxidative stress.
