ABSTRACT
Objective To evaluate the relevance and accuracy of fibrinogen (Fib) detection by using PT-der assay and Von-Clauss assay on Sysmex CA-1500 Automated Coagulation Analyzer .Methods PT-der assay and Von-Clauss assay on Sysmex CA-1500 Automated Coagulation Analyzer were employed to detect the plasma Fib concentrations of 755 blood samples .The dilution ratios of samples with high Fib concentration were 1∶8 ,2∶7 ,3∶6 ,4∶5 ,5∶4 ,6∶3 ,respectively .The dilution ratios were served as the abscissa ,and the Fib concentrations measured by two methods as the ordinate ,a simple linear regression analysis was per-formed .Results When Fib concentration was in 2 .0- <6 .0 g/L ,the Fib value obtained by Von-Clauss assay was higher than that by PT-der assay(P<0 .01) .When Fib concentration was below 2 .0 g/L or above 6 .0 g/L ,the Fib value obtained by PT-der assay was higher than that by Von-Clauss assay(P<0 .01) .The linear regression equations of PT-der assay and Von-Clauss assay were Y=4 .537 7X+1 .551 3(R2 =0 .897 3) ,Y = 7 .792 2X+ 0 .290 0(R2 =0 .980 5) ,respectively .Conclusion Von-Clauss assay can better reflect the Fib level of human body which has a blood clotting function .
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the distributions of genotypic and allelic frequencies of intercellular adhesion molecule-1 (ICAM-1) gene K469E and platelet endothelial cell adhesion molecule-1 (PECAM-1) gene C373G in patients with preeclampsia.</p><p><b>METHODS</b>Polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) and DNA sequencing were used for detecting ICAM-1 gene K469E and PECAM-1 gene C373G genotypes in 110 women with preeclampsia and 110 normotensive pregnant women in comparison with their clinical characteristics.</p><p><b>ESULTS</b>The distributions of observed and expected genotype frequencies were consistent with Hardy-Weinberg equilibrium. No significant differences were found in the genotype and allele frequencies of ICAM-1 gene K469E between the two groups (P>0.05), but the CC and the CG genotype frequencies of PECAM-1 gene C373G were significantly different between them (P<0.05). The relative risk for preeclampsia of CG genotype was 1.959 folds of that in CC genotype carriers (OR=1.959, 95%CI: 1.090-3.520, P=0.024), and this association still existed after adjustment for age, gravidity, parity and BMI in logistic regression models. The C373G allele frequencies showed no significant difference between the two groups (P>0.05).</p><p><b>CONCLUSIONS</b>The CG genotype of PECAM-1 gene C373G genetically predispose the carriers to preeclampsia, while ICAM-1gene K469E polymorphisms is not associated with preeclampsia.</p>

[Objective]To evaluate the clinical effect of the plastic splint on treatment of Colles fracture.[Method]A total of 105 patients with Colles fracture were collected between September 2002 and August 2008.All patients were perfromed using the plastic splint afrer diaplasis.According to Gartland and Werley scoring syste,the function of wrist was evaluated after 3 months.[Result]There are only 2 cases losing during treatment,103 cases were finished.The average excellent to good case was 90.3%,including 80 cases of being excellent,13 of being good,7 of being fair and 3 of being poor.[Conclusion]The plastic splint is exactly effective to treatment Colles fracture,especially,it could effectively relieve swelling and improve the contour of the wrists.Theses all rely on reasonable biomechanics design.
