Correlation of serum arylesterase activity on phenylacetate estimated by the integrated method to common classical biochemical indexes of liver damage / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

The correlation of serum arylesterase (PON1) activity on phenylacetate determined by an integrated method to classical biochemical indexes of liver damage was investigated for the use of PON1 activity to evaluate liver damage. PON1 reaction curve as absorbance at 270 nm for 0.20 mmol/L phenylacetate hydrolysis was analyzed by the integrated method to determine maximal PON1 reaction rate. Classical biochemical indexes of liver damage were determined routinely. The 95% confidence threshold of PON1 activity in sera from healthy individuals was 2.12 mkat/L [(4.73+/-1.31) mkat/L, n=105]. PON1 activity in clinical sera was closely correlated to serum albumin, total protein and the ratio of albumin to globulins, but was weakly correlated to both direct and total bilirubin in serum. There were no correlations of PON1 activity to gamma-glutamyltransferase, alkaline phosphatase, alanine aminotransferase and aspartate aminotransferase. Among 127 clinical sera with PON1 activity>2.12 mkat/L, there were 92% healthy individuals examined by albumin, 90% healthy individuals examined by total protein, 88% healthy individuals examined by total bilirubin, 86% healthy individuals examined by direct bilirubin and 64% healthy individuals examined by the ratio of albumin to globulins, respectively. In each group of healthy individuals judged by classical biochemical indexes of close correlation to PON1 activity, percentage of healthy individuals examined by PON1 activity was always >80%. These results suggested PON1 activity on phenylacetate estimated by the integrated method was also suitable for the evaluation of liver damage.

The fetus protection effects of Zhixue Baotai Decoction on women of early threatened abortion with dark area surrounding pregnancy sac / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the fetus protection effects of Zhixue Baotai Decoction (ZBD) on women of early threatened abortion with dark area surrounding pregnancy sac.</p><p><b>METHODS</b>The 105 patients with early threatened abortion, in whom vaginal bleeding was shown already, were randomly assigned to the treatment group and the control group, who were treated respectively with ZBD and progesterone to protect fetus. The efficacy of treatment was evaluated by dynamic monitoring of serum hormone and B-ultrasonic examination.</p><p><b>RESULTS</b>Among the 54 cases in the treatment group the fetus was protected successfully, showing a fetus protecting rate of 81.5%; while among the 51 cases in the control group, the protection was effective in 22 cases (43.1%), the success rate in the former was better (P<0.01). The dark area was absorbed in 16 out of 19 cases (84.2%) in the treatment group, while in the control group absorption occurred only in 6 out of 17 (35.3%).</p><p><b>CONCLUSION</b>The effect of ZBD is superior to that of progesterone in treating women of early threatened abortion with dark area surrounding pregnancy sac.</p>
