Reverse transcription-PCR and methylation-specific PCR (MSP) were used to determine the expression levels of Syk gene and the methylation status of its promoter in tissue samples from 60 patients with cervical cancer, 50 patients with cervical intraepithelial neoplasia (CIN), and 20 normal controls. We also analyzed the association of the methylation status and expression levels of Syk gene with linicopathological features of patients. The expression rates of Syk gene in 20 normal cervical tissue samples and 18 CIN Ⅰ samples were both 100% ; those of CIN Ⅱ- Ⅲ and cervical carcinoma were 56% (18/32)and 35% (21/60) respectively. Among cervical carcinoma patients, the expression of Syk mRNA was detected in one out of 13 cases with lymph node metastasis (1/13) and in 20 out of 47 cases with no lymph node metastasis (43%). The methylation of Syk gene in promoter region was detected in 34 out of 60 cases of cervical carcinoma (57%) ; while there was no methylation in CIN cases. In 13 cases with lymph node metastasis, 11 were found to have the methylation of Syk gene. The methylation rate of Syk promoter in cervical carcinoma was higher than that of CIN tissue( x~2 = 7. 13, P <0. 01 ). The methylation status of Syk gene was correlated with the lymph node metastasis ( P< 0. 05 ), but not with other clinicopathological parameters ( P > 0. 05). There was a significant correlation between methylation status and expression level of Syk gene ( P < 0. 05 ). The hypermethylation leads to silencing of the Syk gene in human cervicalcarcinoma. Syk hypermethylation may be associated with oncngenesis, metastasis of cervical carcinoma.

Objective To observe the management and outcome of the cardiac tamponade patients during the ablation procedure using two different anticoagulation strategies. Methods All the patients developed tamponade during the ablation procedure were enrolled from January 2007 to December 2013 in our center. In group 1, warfarin was discontinued 3 to 5 days before the procedure and low molecular weight heparin (LMWH) was administered subcutaneously until ablation procedure day. In group 2, warfarin was not discontinued and the international normalized ratio INR was to maintained between 2 and 3. Results There were 27 patients (0.6%) developed cardiac tamponade out of a total 4487 patients received ablation in our center. The baseline clinical characteristics including age, left atrium, the heparin dose and ACT during the procedure had no signiifcant difference between the groups, except that the INR was higher in the group 2 (0.9±0.1 vs. 2.3±0.5, P<0.001). There was no signiifcant difference in the amount of pericardiac drainage between the two groups (365±222 ml vs. 506±300 ml, P=0.137). Two patients in group 1 patient (11.1%) and 1 in group 2 (11.1%) needed emergency surgical repair (P>0.999). The median hospital day was similar in the 2 groups [(9.6±3.3) d vs. (12.1±4.5) d, P=0.167]. There were no other serious complications and no hospital death. Conclusions Non-discontinuation of warfarin during peri-procedural catheter ablation of AF is not signiifcantly different to bridging with LMWH in the management and outcome of acute cardiac tamponade.
