"A combination of D-dimer and calf circumference provides an easy and effective means of excluding DVT in patients suspected of having proximal DVT," the authors write."A combination of D-dimer less than 0.5 ng/mL and calf circumference of 2 cm or less reliably excludes DVT in the acute setting and allows for use of DU in a nonemergent setting. Patients with a positive D-dimer or calf circumference of more than 2 cm require emergent DU to exclude DVT."

同时检验D-dimer与小腿的肿胀情形，能让我们简单有效地在疑似罹患近端深部静脉血栓患者中先行过滤；若D-dimer小於0.5 ng/mL，同时小腿肿胀达2公分，仍无法分辨者，可尝试安排都卜勒超音波检查来做诊断确认；一旦D-dimer 呈阳性反应，或小腿肿胀超过2公分以上者，便需要进行紧急的都卜勒超音波检查，才能确认诊断是否罹患深部静脉血栓。

The results were as follows the change of vitamin C content was a "trial apex"-shape curve, higher in young fruit,incrustation and maturation stages, lower in other periods; the total acid content was the highest in young fruit, after that, it decreased rapidly, maintained lower level, and reached lowest when the fruit matured; the total content of soluble sugar inosculated with the fruit development, it was high when the fruit development was quick, and low when the fruit development was slow; before 59 d after anthesis, the reducing sugar content was high in the total content of soluble sugar and after that ,the nonreducing sugar content was high; before 45 d after anthesis, free amino acid content was obviously correlated with protein content, and they inosculated with the fruit development;4559 d after anthesis, free amino acid content increased quickly, and protein content decreased gradually, this was also the most shaping period of the embryo and endosperm.

结果表明，Vc含量呈&三峰&型曲线，幼果时、硬核后和成熟时较高，其他时期较低；有机酸含量以幼果期最高，以后迅速下降并维持较低水平，果实成熟时含量最低；可溶性总糖含量与果实发育状况基本相吻合，果实发育速度快时含量较高，慢时较低；在谢花后59 d以前，可溶性糖以还原糖为主，之后以非还原糖为主；游离氨基酸和蛋白质含量，在谢花后45 d以前两者呈高度相关，且与果实生长速度相吻合，谢花后4559 d是胚和胚乳的主要形成期，此期游离氨基酸含量迅速增加，蛋白质含量持续下降。西北林学院学报21卷第5期张传来等金光杏梅果实发育期间主要营养成分动态变化研究

The dynamic simulation test showed that, the removal rate of TN、 NH_3-N、TP of Oenanthe javanica floating-bed was positive correlated with water temperature. The average removal loading rate of TN and TP were 0.80g/m.~2·d and 0.11g/m~2·d, respectively. The inhibition on algae was steady and the average inhibition rate was 57.3%. We also got the best value of hydraulic loading rate, floating-bed coverage rate, water depth under dynamic polluted river. They were 1.0m~3/(m~2·d)、 30%、 30cm.

动态模拟试验表明：水芹菜浮床对动态污染河水中TN、NH_3-N、TP的去除率与水温正相关，TN的平均去除负荷为0.80g/m~2·d，TP的平均去除负荷为0.11g/m2~2·d，对藻类的抑制作用较为稳定，平均抑制率为57.3%；获得了对动态污染河水最佳净化效果时的水力负荷参数为1.0m~3/(m~2·d)、浮床覆盖率为30%、水深为30cm。

Methods Forty rats were randomized into normal control group and FS group. The normal control group was fed with conventional forage. FS group was fed with dry forage mixed with FS powder for 3 months, the preliminary dose of FS was 200 mgkg^(-1)d^(-1) and then increased progressively by l00 mgkg^(-1)d^(-1) to ensure over half of the rats having diarrhea, and the final dose was 2800 mgkg^(-1)d^(-1). The frequency and amplitude of colic slow wave were detected and the changes of myenteric plexus and ICC were observed by zinc iodide -osmic acid staining method.

方法］SD大鼠40只，随机分为2组：正常对照组、番泻叶组（饲以含番泻叶粉的乾饲料，起始剂量为200 mgkg^(-1)d^(-1)，以100 mgkg^(-1)d^(-1)剂量递增，保持对半数以上动物有泻下作用，连续3个月，终剂量为2800 mgkg^(-1)d^(-1)，检测大鼠结肠慢波的频率及振幅，采用碘化锌－锇酸法观察肌间神经丛及ICC变化。

Methods 20 rats were randomly divided into A, B, C, D and E group. The models of cerebral anoxia in group A and C were made by hypopiesia and hypoxia, and the models of hypoxia-reoxgenation were made in group B and D. 24h and 1h before establishment of models, ginsenoside Rb3 was injected peritoneally in rats of group C and D, respectively. The number and form of GABA-like immunoreactive neurons in hippocampus CA1 area of rats after brain hypoxia-reoxgenation were investigated with immunohistochemistry.
