Objective To investigate the clinical value of detecting D-Dimer(DD) combined with cTnⅠ in the early diagnosis of acute myocardial infarction(AMI).Methods The plasma DD and cTnⅠ were determined and compared in 47 patients with AMI(observation group) and 41 patients excluding cardiovascular diseases(control group).Results The positive rates of DD and cTnⅠ in observation group were higher than the control(78.72% vs 9.75%,87.23% vs 0,both P<0.01).The separate test of DD and cTnⅠ in observation group,sensitivity were 78.72%,87.23% respectively,specificity were 90.24%,100% respectively.While the union test,sensitivity and specificity were 93.61%,95.12%.Conclusion Determining plasma DD combined with cTnⅠ can obviously enhance the early diagnosis rate ofAMI.
Objective To investigate the clinical value of detecting platelet parameters and high sensitivity C-reactive protein(hs CRP) in patients with acute myocardial infarction(AMI).Methods The platelet four parameters,including platelet count(PLT),mean platelet volume(MPV),platelet distribution width(PDW) and platelet-large cell ratio(P-LCR) Hs-CRP were detected in 46 patients with AMI and 32 health examiners(control group).Results The levels of PLT in the AMI group were lower than that of the control group,while the levels of MPV,PDW and P-LCR in AMI group were higher than that of the control group(P < 0.01).The level of Hs-CRP in AMI group were higher than that of the control group(P < 0.01).Conclusion The levels of platelet parameters and Hs-CRP are closely correlated with the occurrence and progress of AMI.They may be used as important indexes of the attack and severity degree of AMI.
AIM: To investigate the effects of deep-frozen treatment on the immune response of bone-patellar tendon-bone(BPB) xenograft rejection.METHODS: A muscle pocket model was used to study the immune response of rat to deep-frozen treated BPB xenograft from guinea pig,autograft and fresh xenograft served as controls.The expression of T-cell surface activation antigen CD25 in the peripheral blood and the morphological changes of the implants were used to measure the immune response.RESULTS: The expression of CD25 in CD4+,CD8+ cells greatly increased 3 d after fresh BPB xenograft,the obvious difference to that of autograft(P0.05) was observed.It reached a peak level 14 d after fresh BPB xenograft and didn't decrease 35 d after transplantation.The expression of CD25 in CD4+,CD8+ cells was greatly inhibited in deep-frozen treated BPB xenograft.Its expression was delayed and just had a small increase 14 d after transplantation.The P values were all less than 0.05 compared to those of fresh xenograft at every time-point after transplantation.Histologic examination showed that there were a few lymphocytes surrounding the bone and tendon tissue in deep-frozen treated BPB xenograft,but the lymphocytes hadn't invaded into the tissues.No tissue necrosis,but a clear tendon structure and regular fibrogen arrangement were observed.There were large amount of fragmentary lymphocytes infiltrating into or surrounding the bone and fibrogen tissues after fresh xenograft,the bone was broken into pieces,the tendon structure was unclear and the fibrogen arrangement was irregular,quite a few of inflammatory cells such as acidophilic granulocytes and macropolycytes were found in some slices.CONCLUSION: Deep-frozen treatment markedly reduces BPB xenograft antigenicity and inhibits the immune rejection.
OBJECTIVE:To investigate the relation between CD4(+) and CD8(+) T lymphocyte infiltration and apoptosis of the neurons in the local traumatic brain tissue after brain trauma in rats. METHODS:In rat models of brain trauma, the changes in the number of CD4(+) and CD8(+) T lymphocytes and the apoptosis of neurons in the local traumatic brain tissue were observed by immunohistochemistry at different time points after brain trauma. RESULTS:Twenty-four hours after brain trauma, a significant increase in the number of CD4(+) and CD8(+) T lymphocytes occurred in the injured brain tissue, both reaching the highest levels on day 10, at the point of which the number of CD4(+) cells increased by about 15 folds and that of CD8(+) cells by about 20 folds compared with the control groups. The CD4(+) and CD8(+) T lymphocytes both began to decrease 30 days after the injury. A similar pattern of alterations was found in the apoptosis of neurons in the local brain tissue. Correlation analysis demonstrated a close positive correlation between the changes in CD4(+) and CD8(+) lymphocyte numbers and the number apoptotic neurons in the injured brain tissue. CONCLUSIONS:Brain trauma induces obvious increases in CD4(+) and CD8(+) T lymphocytes and enhanced cellular immune response in the injured brain tissue to mediate neuronal apoptosis and further exacerbate the brain tissue injuries.
