Objective:To detect the expressions of survivin, galectin-3 and thyroid peroxidase in papillary thyroid microcarcinoma ( PTMC) and cancer adjacent normal tissue to explore the clinical significant.The correlations between the expressions of survivin,Gal-3 and TPO with BRAFV600E gene mutation in PTMC were analyzed.Methods: The expressions of survivin,Gal-3 and TPO were measured by immunohistochemical ( IHC ) method in 56 cases of PTMC tissue and adjacent normal tissue; BRAFV600E mutation was detected by PCR amplification and subsequently sequencing.Chi square test was used to analyse the relation in the expression rates of survivin,Gal-3 and TPO and BRAFV600E gene mutation.Results:The survivin and Gal-3 were strongly expressed but TPO was negatively expressed.The survivin and Gal-3 were negative in adjacent normal tissues but TPO was expressed.There were sig-nificant differences in the expression rates of survivin, Gal-3 and TPO between PTMC tissue and adjacent normal tissue (all P<0.001).The BRAFV600E mutation rate (32.1%) and the expression rates of survivin,Gal-3 and TPO in PTMC tissue were found to be positively related to lymph node metastases (P=0.009,P=0.025,P=0.007,P=0.008),and negatively related to gender and age (all P>0.05).There were no correlation was found between the expressions of survivin,Gal-3,TPO and the BRAFV600E gene mutation in PTMC(all P>0.05).Conclusion: The strong expressions of survivin and Gal-3,the mild expression of TPO and BRAF mutation may be important in the development of PTMC,and the detection of BRAFV600E gene mutation and the expressions of survivin, Gal-3 and TPO could be used to the judgment of pathogenetic condition and prognostic outcomes.

Objective:To explore the effect of sarpogrelate on platelet function in patients at the bridging stage before coronary artery bypass grafting (CABG).
Methods: A total of 40 consecutive patients with peripheral artery stent and scheduled for CABG in our hospital from 2011-05 to 2013-04 were enrolled in this study. The patients were randomly divided into 2 groups, Low molecular weight heparin (LMWH) alone group, n=19 and Sarpogrelate+LMWH group, n=21. The medications started at 5-7 days before CABG and stopped at 24 h before CABG. The platelet inhibition rates (platelet aggregation induced by collagen+ serotonin) were examined and compared between 2 groups at the baseline (before randomization), 24h and 1h before CABG respectively.
Results: The platelet inhibition rates were similar between 2 groups at the baseline (87.33 ± 6.82) % vs (86.11 ± 6.87) %, P=0.577 and 1h before CABG (62.60 ± 12.39) % vs (56.19 ± 14.99) %, P=0.148. At 24h before CABG, the platelet inhibition rate in Sarpogrelate+LMWH group was higher than that in LMWH alone group (83.87 ± 8.99)%vs (63.13 ± 10.88)%, P<0.001. Compared with the baseline, the falling range of platelet inhibition was lower in Sarpogrelate+ LMWH group at 24h before CABG, (3.46 ± 6.18) % vs (22.98 ± 9.43) %, P<0.001 and the falling range was similar between 2 groups at 1h before CABG (24.73 ± 14.19)%vs (29.92 ± 14.28)%, P=0.257.
Conclusion: Sarpogrelate + LMWH may result better platelet inhibition rate with quicker recovery of platelet function upon the medication stopping, which might be a feasible management in patients at the bridging stage before CABG.
