Objective To investigate the effect of different antiplatelet or anticoagulation therapy on postoperative pocket hematoma after electrophysiological devices placements (EPD). Methods The clinic data of 410 patients who took anti-platelet or anticoagulation therapy and needed to be implanted EPD from February 2012 to February 2015 were selected. According to the type of therapy, patients were divided into 4 groups:dual anti-platelet drug (DAP) treatment group (DAP group, 114 cases), low-molecular-weight heparin (LMWH) bridging treatment group (LMWH group, 98 cases), aspirin (ASA) alone group (ASA group, 94 cases) and warfarin group (104 cases). The incidence of pocket hematoma after electrophysiological devices placements was observed. The risk factors of pocket hematoma were analyzed. Results The incidence of pocket hematoma was higher in LMWH group than that in the other 3 groups: 18.4% (18/98) vs. 4.4% (5/114), 3.2% (3/94) and 2.9% (3/104), and there was statistical difference (P<0.05). But there were no significant differences in the incidence of pocket hematoma among DAP group, ASA group and warfarin group (P>0.05). The multiple Logistic regression analysis revealed that LMWH bridging therapy was an independent risk factor for the development of pocket hematoma (OR=7.105, 95%CI 1.872-17.283). Conclusions LMWH bridging therapy can increase the risk of development of pocket hematomas after electrophysiological devices placement.

Background and Purpose:Cervical cancer is one of the most common malignant neoplasms among women.The 5-year survival for patients with early stage disease is over 70%.While it is generally accepted that either radical surgery or radiotherapy can achieve cure for the majority of patients with early-stage cervical cancer,there is no standard approach to the patients with bulky disease,whose prognosis remains very poor in spite of the therapeutic advances achieved in recent years.Neoadjuvant chemotherapy has been used as part of the multidisciplinary treatment before either operation or radiation therapy.Although the approach still had many controversies,numerous studies have supported its effectiveness in bulky cervical cancer.The present study was conducted to explore whether neoadjuvant chemotherapy with the combination of vincristine,bleomycin and cisplatin could improve the operability and pathological response rate in Ⅰb_(2)~Ⅱb bulky cervical cancer patients.Methods:A total of fifty-six patients with bulky cervical cancer were histologically diagnosed and staged into Ⅰb_(2)~Ⅱb according to the standards of International Federation of Gynecology and Obstetrics(FIGO) and randomly selected,including 15 cases with Ⅰb_(2),15 with Ⅱa,26 with Ⅱb.They were treated by a regimen of PVB chemotherapy for 2 cycles and followed by operation.The immediate response and adverse effects were analyzed.Results:The overall response rate was 78.6%.The resectability rate for surgery after chemotherapy was 100%.No intolerable toxic and adverse effects were recorded during neoadjuvant chemotherapy.Preoperative neoadjuvant chemotherapy can apparently increase the possibility of resection by operation and enhance the remission rate.The primary tumor sizes were significantly decreased after chemotherapy before surgery(P
