Methods: Semi-quantitative RT-PCR was carried out to detect the level of sFlt-1 mRNA in placental tissue of 10 preeclampsia (study group) and 10 normotensive pregnancies (control group); ELISA was used to detect the serum level of sFlt-1 in peripheral venous blood and uterine venous blood in control group (n=35) and study group (n=35), and furthermore to detect the volume of peripheral venous blood sFlt-1 in early, middle and later pregnancies. Results: sFlt-1 mRNA of placental tissue was significantly higher in preeclampsia than that in normal pregnancy. The serum level of sFlt-1 of peripheral vein in preeclampsia was higher than that in normal pregnancy ([ 5639.6±3190.5] pg/ml vs[ 2194.4±635.8 ] pg/ml, P<0.01) , so did the serum sFlt-1 of uterine vein in preeclampsia and control group ([7673.3±2295.8] pg/ml vs[ 3056.6±784.6] pg/ml, P<0.01), indicating that the volume of sFlt-1 of uterine vein blood was significantly higher than that of peripheral venous blood (P<0.01). The serum level of sFlt-1 in early, middle and later pregnancy were (31.7±19.6) pg/ml (n=10), (994.0±302.1) pg/ml (n=10), (2194.4±635.8) pg/ml (n=35), respectively, showing that the level of sFlt-1 in peripheral venous blood increasingly elevated with the development of pregnancy (P<0.01). Conclusion: Preeclampsia is associated with increased level of sFlt-1 which might be largely from placenta during pregnancy.展开更多

Leaf discs were permeabilized with iso-propanol to facilitate the uptake of the enzyme substrate by intact tissues and to improve the enzyme assay. Bacterial infection significantly enhances β-1,3 glucanase activity of sensitive cultivars whereas significantly decreased that of the resistant one. Low concentrations of salicylate increase the hydrolase activity whereas jasmonic acid do not act as an elicitor of the enzyme and β-1,3 glucanase, such as laminarin, significantly inhibits the production of β-1,3 glucanase. Thus, the enzyme must be considered as a sensitivity factor induced by the pathogen.展开更多

Methods Fifty patients with herniation of lumbar intervertebral disc were treated with eleetroaeupuncture at the points of Shiqizhui （十七椎 EX-B 8）, Yaoyangguan（腰阳关 GV 3）, Huantiao （环跳 GB 30）, Yanglingquan （阳陵泉GB 34） and waist-strengthening exercises. The total scores of general symptoms were evaluated before the treatment and after four months and seven months of treatment to compare the therapeutic effects. Results The total scores of general symptoms after four months and seven months of treatment were 15.30±5.66 and 19.08±4.57 respectively, which were much higher than the score of 7.42±2.20 before the treatment （both P〈0.01 ）, in addition, the score after seven months of treatment was higher than that after four months of treatment. The variation of scores in patients with different types after treatment was statistically significant （P〈0.05）, and the best effect can he seen in the blood stagnation type of patients with herniation of hnnbar intervertebral disc, then less the patients with liver and kidney deficiency type. Conclusion Electroacupuneture plus waist-strengthening exercises has a satisfactory therapeutic effect on herniation of lumbar intervertebral diste, the longer course of treatment is, the beffer therapeutic effect achieved.展开更多
