ABSTRACT
Objective To investigate thrombelastogram (TEG) correlation between parameters and platelet count in perioperative period patients.Methods Selected 139 patients,69 cases with thrombocytopenia,35 cases with normal platelet number and 35 cases with thrombocytosis from 2012 January to 2014 May,monitored TEG,blood coagulation function and the change of blood routine during perioperative period.Spearman test was used to analyze the different level of platelet count and other coagulation parameters.Results The positive correlation between platelet count and TEG parameters were:MA (r=0.57,P＜0.57),Angle (r=0.54,P＜0.000 1),CI (r=0.57,P＜0.000 1),and R was negatively correlated with platelet count (r=-0.27,P＜0.000 1).There was no significant correlation between PT,APTT and platelet count.In mild lack of platelet group [(87.34 ± 10.43) × 109/L] and normal group [(198.47 ± 45.30) × 109/L],platelet count was positively correlated with MA and Angle.In severe lower [(39.33±10.63) × 109/L] and higher group [(330.34±35.43) × 109/L],there was no correlation between platelet platelet count with MA or Angle.Conclusion Platelet count was significantly correlated with CI,Angle and MA,but in patients with moderately severe lower platelet and platelet increase the platelet count do not reflect the aggregation function,MA is more sensitive response to platelet function.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the expression of CCAAT/enhancer binding protein beta (CEBPB) in gastric carcinoma tissues and its association with clinicopathological features and prognosis.</p><p><b>METHODS</b>CEBPB protein expression level was detected by immunohistochemistry method in resected gastric carcinomas and adjacent gastric mucosa tissues (n=81), and its association with clinicopathological features and prognosis was analyzed.</p><p><b>RESULTS</b>The immunohistochemical staining of CEBPB was predominantly in the nucleus with some cytoplasmic staining. As a result, 16% (13/81) of the gastric carcinomas were stained positively, whereas there was hardly positive expression in adjacent gastric mucosa tissues. There was a significant association between the expression of CEBPB and distant metastasis on univariate analysis (P<0.05). The median survival time in patients with positive CEBPB expression was significantly lower than those with negative CEBPB expression (19.4 months vs. 45.2 months, P=0.024). Multivariable analysis showed that CEBPB was independently associated with prognosis (HR=2.544, 95%CI:1.154-5.610, P=0.021).</p><p><b>CONCLUSION</b>Up-regulation of CEBPB suggests poor prognosis in patients with gastric cancer.</p>
