ABSTRACT
Objective To establish normal reference interval for four items of blood coagulation on ACL‐TOP Automatic coagu‐lation analyzer .Methods The fasting anti‐coagulation blood samples were collected from 1 268 inpatients and people conducted physical examination ,all subjects without liver disease ,history of blood disease and coagulation disfunction .The prothrombin time (PT) ,activated partical prothrombin time(APTT) ,thrombin time(TT) and serum levels of fibrinogen(FIB) were determined by u‐sing ACL‐TOP automatic coagulation analyzer which was producted by America IL company .And data of determination results were used to establish the normal reference intervals of indexes in this laboratory .Results The precision and accuracy of this analy‐zer was good .There were differences of normal reference intervals between which established in this laboratory and which provided by the manufacturer .Conclusion Each laboratory should establish its own normal reference interval ,not blindly refer to reference interval provided by regents manual .
ABSTRACT
AIM: To investigate whether salidroside has influence on the activities of endothelial progenitor cells (EPCs) and its mechanism.METHODS:Mononuclear cells from normal human peripheral blood were cultured in fi-bronectin coated flasks in endothelial progenitor medium .After 7 d, EPCs were characterized as adherent cells with acLDL-DiI uptaking and lectin binding by direct fluorescent staining .The proliferation and migration of EPCs were analyzed by MTT assay and Transwell chamber assay , respectively.The EPCs adhesion assay was performed by re-plating the cells on fibronectin-coated dishes , and then adherent cells were counted .NO and Akt protein were also detected .RESULTS:Sali-droside promoted EPCs proliferative , migratory and adhesive capacities in a concentration dependent manner .Salidroside also increased NO secretion , and the level of phosphorylated Akt protein .However , the effects of salidroside on EPCs were inhibited by phosphoinositide 3-kinase inhibitor LY294002.CONCLUSION:Salidroside regulates the activity of EPCs by phosphoinositide 3-kinase/Akt signaling pathway .
ABSTRACT
<p><b>OBJECTIVE</b>To observe the effect of single administration of mercury- containing preparation Jiuyi Dan (calcined gypsum-Shengdan 9: 1) and Shengdan on acute toxicity of rabbits, in order to assess the safety of tested drugs.</p><p><b>METHOD</b>The rabbits were randomly divided into 4 groups: the calcined gypsum group (excipient control), the Jiuyi Dan group, the 90 mg Shengdan group and the 180 mg Shengdan group. After 270 mg of calcined gypsum, 300 mg of Jiuyi Dan, 90 mg of Shengdan, and 180 mg of Shengdan were used on the surface of wounds (5 cm x 5 cm) on two sides of rabbit back for 5 h, the surfaces of wound were washed by water. The bloods were taken from the rabbit hearts before and after the drug administration for 24 h, 72 h, 7 d and 14 d for determining Hg level in blood and liver & kidney function indicators (ALT, AST, CREAT, and BUN). The rabbits were dissected after the drugs treatment for 14 d, and pathological tests were made for their livers and kidneys.</p><p><b>RESULT</b>Compared with the calcined gypsum group, the 90 mg Shengdan group and the 180 mg Shengdan group showed significant increase (P < 0.01 or P < 0.05), as evidenced by increase in CREAT for 24 h and 72 h and increase in BUN for 24 h and on 7 d. AST is significantly increased as well (P < 0.01) for 24 h and 72 h compared to that of the group before drug treatment. The Hg level in blood was significantly enhanced (P < 0.01) after the rabbits were administrated with drugs for 24 h to 72 h. The pathological changes in livers and kidneys of rabbits were observed in the two doses of Shengdan treatment groups.</p><p><b>CONCLUSION</b>The Hg blood levels were increased significantly in an obvious dose-effect relationship in all drugs treatment groups. Liver & kidney function indicators were influenced by Shengdan treatment to some extent. Meanwhile, pathological changes in rabbit livers and kidneys were also caused by Shengdan, while Jiuyi Dan has no significantly effect on livers and kidneys.</p>

Based on the standards for mental developmental re-tardation set up by WHO in 1985,by applying IQ andadaptation to social behavior as indexes for observa-tion with testing methods for intelligence commonlyaccepted,we have observed the effects in 128 suchcases treated by combined use of acupuncture,adhe-sive—pressing therapy at auricular points and drugplastering at points.Results showed that our therapyis conducive to the improvement of intelligence in suchcases.
