ABSTRACT
[Objective]To observe the effect of Chinese herbs for activating blood stasis on the shape and function of the endothelial cells in rat aorta.[Method]Rat models of PCOS have been established according to Poresky,randomized into animal model and Chinese medicine group(TCM group),normal rats were control group.Measure the serum level of FSH,LH,T,INS and plasma ET PAI-1,and observe the endothelial cell morph.[Results] In the model group,the endothelia cells of the aorta were contracted,with discontinuous basement membrane,inflated chondriosome,the middle layer smooth muscles tending to move inside and out of the normal shape of intraendothelial junction.In the TCM group,the endothelial cells appeared flat,arranging along the long axis of the blood vessels,normal endothelial cell integrity with scanty cytoplasm and the microscopic appearance shows highly developed golgiosome rough endoplasmic reticulum and smooth endoplasmic reticulum.The model group had a more increased serum level of PAI-I and ET than those of the control group,and showed the significant difference(P0.05).The TCM group had more decreased level of ET than those of the normal group(P
ABSTRACT
Objective To analyse correlated risk factors of evolving cerebral infarction(ECI).Methods The follow data was recorded in the acute cerebral infarction (ACI)cases when they were admitted :sex,age,systolic blood pressure(SBP),diastolic blood pressure(DBP),history of disease (diabetes mellitus,hypertension,hyperlipidaemia,cerebral infarction,hyperuricemia or smoking).The following examinations or determinations were done,including:white blood cell count (WBC),platelet count (PLT),blood gluconate(GLU),PT-INR,fibrinogen(FG),TT-INR,APTT-INR,C-reactive protein(CRP),D-dimer(D-D),products of fibrin degradation(FDP),anti-thrombin Ⅲ(ATⅢ),apolipoprotein A(apoA),apolipoprotein B(apoB),blood urea nitrogen(BUN),creatinine(CR),triglyceride (TG),high density lipoprotein (HDL),low density lipoprotein (LDL),very low density lipoprotein (VLDL),GOT,lactate dehydrogenase(LDH),creatine phosphokinase (CPK),MB isoforms of creatine phosphokinase (CPK-MB),? hydroxybutyrate dehydrogenase (?-HBDH),troponin I(TnI),cerebral CT or MRI and carotid ultrasonography.The patients were divided into two groups,ECI and completed cerebral infarction (CCI),according whether neurons function scale deteriorated.When cases of both groups exceeded 50,we took statistic test by SPSS10.0 statistic software.Results 8 of the above 46 markers had significant defference between the two groups,including CRP,WBC,apoB,GLU,LDH,CPK-MB,?-HBDH and DBP.ECI was more common in patients who had lower DBP or higher CRP,WBC,apoB,GLU,LDH,CPK-MB,?-HBDH when they were admitted.Conclusion The increase of CRP,WBC,apoB,GLU,LDH,CPK-MB,?-HBDH or decrease of DBP when patients are admitted can be predictive markers of ECI.
