AIM: To investigate the expression pattern of apolipoprotein M (apoM) protein in renal cortex of a-cute renal failure ( ARF) rats with reperfusion. METHODS: Seventy - five male rats were randomly divided into sham operation group (re =25) , ARF group (n =25) and pyrrolidine dithiocarbamat (PDTC) group (n =25) , five subgroups at time points of 3 h, 6 h, 12 h, 24 h and 48 h after reperfusion were set up in each group. The expressions of apoM in cytoplasm and NF - κB p65 in nucleus of renal cortex were detected at the indicated time points. RESULTS: The expression of apoM in ARF group was obviously higher than that in sham operation group ( P <0.01 ) , and two peaks were detected, the first peak was at 6 h after reperfusion, while the second one was from 24 h to 48 h. The tendency of apoM expression in PDTC group was similar to that in ARF group, while the expression in every subgroup was prevalently lower than that in ARF group (P < 0.01). Otherwise, a significant correlation ( r = 0.852, P < 0.01) was found between the expression of apoM and NF -κB p65.CONCLUSION: The results indicate that apoM feasibly take part in the pathogenesis of ARF through the inflammatory reaction mediated by NF - κB.

Objective To improve the current standard method of measuring urinary iodine by As (Ⅲ)-Ce4+catalytic spectrophotometry, reducing the amount of arsenic toxic reagent used to decrease environmental pollution,and make the modified method with good precision and accuracy. Methods For improving the current standard method of measuring urinary iodine, amount of arsenious acid solution was reduced from 0.100 mol/L H3AsO3(which contains NaCl 25 g/L) 2.5 ml to 0.025 mol/L H3AsO3(which contains NaCl 40 g/L) 2.5 ml;amount of ceric ammonium sulfate solution was reduced from 0.076 mol/L 0.30 ml to 0.025 mol/L 0.30 ml;photometric wavelength was changed from 420 nm to 400 nm. The new modified method was evaluated by standard curve linearity and linear range, sample detection limit, precision, accuracy, and urinary iodine values, and the rates of absorbance change in the test process were compared with the current standard method. Results The calibration relation of C= a + blgA (C: iodine concentration, A : measuring absorbance) in the new modified method existed when As3+-Ce4+ catalytic reaction was kept at a certain stable temperature range between 20 - 35 ℃ and in certain stable reacting time. The linear range of the calibration curve was 0 - 300 μg/L and the linear correlative coefficient was - 0.9998. The detection limit for iodine was 4 μg/L(0.25 ml of urine was tested). The test coefficient of variations(CV) were 1.7%(1.1/66.0), 1.8%(1.4/76.0), 2.0%(3.0/147.5), 1.6%(4.2/265.5) when measuring urine samples with iodine concentration of 66.0, 76.0, 147.5, 265.5 μg/L, respectively. The average recovery was 100.6% with a range of 95.0% (57.0/60.0) - 103.7% (62.2/60.0) when measuring 4 urine samples containing different iodine concentration, and average recovery was 101.0% (40.4/40.0), 100.4% (100.4/I00.0), 100.5% (60.3/60.0),100.4% (100.4/100.0), respectively. The test results of two national standard urinary iodine were all within the given value range and the relative deviation(RD) was < 5.0% and < 2.0% in 20, 25, 30, 35 ℃ test temperature,respectively. No significant difference was found between the results of the 48 urine samples determined by the new modified method and the current standard method(t = 0.634, P > 0.05). The table of suitable combination of As3+-Ce4+ reaction temperature and time for this method was obtained(such as 20 ℃ and 53 min, 25 ℃ and 40 min, 30 ℃and 30 min, etc. ). Compared with the standard method, the rates of absorbanee change of As ( Ⅲ )-Ce4+ reaction in the new modified method were more slowly, which further reducing the determination deviation caused by the temperature fluctuations or measuring time deviation in measurement process. Conclusions This new modified method greatly reduces the amount of arsenic in waste, reduces pollution, saving reagents, and this method is easier to operate with better precision and accuracy, which is suitable for application of measuring iodine in urine.
