ABSTRACT
OBJECTIVE: To explore the clinical regularities and risk factor of abnormal liver function associated with LMWH in pulmonary thromboembolism patients. METHODS: Clinical date of pulmonary thromboembolism patients in use of LMWH was collected and analyzed from January 2008 to December 2016. RESULTS: 97 cases were enrolled. Of them, there were 76 cases were assessed as probable or possible. Single factor analysis showed the the levels of Scr (P=0.000), ALT (P=0.000), AST (P=0.000), γ-GGT (P=0.000), ALP (P=0.023), co-infection (P=0.024) and Ccr (P=0.026) had statistically significant difference. Multivariate analysis indicated that co-infection (OR=1.982, P=0.022) and high level of Scr (OR=1.045, P=0.000) were the independent risk factors of abnormal liver function associated with LMWH in PTE. CONCLUSION: The incidence of abnormal liver function due to LMWH in PTE patients is high. With high level of Scr and/or co-infection patients are high-risk persons of abnormal liver function. It is necessary to dynamically evaluate the liver function during hospitalization. Symptomatic treatment can be significant if the liver function become abnormal.
ABSTRACT
OBJECTIVE: To evaluate the efficacy and safety of rivaroxaban in the treatment of deep venous thrombosis(DVT). METHODS: PubMed, Embase, Cochrane Library, Web of Science, Clinical Trials, CNKI, CBM and WANFANG database were systematically searched. All databases had been searched from up to August 2016. All randomized controlled trials (RCTs) of rivaroxaban therapy in patients with deep venous thrombosis were selected. Meta-analysis was carried out by using RevMan 5.3 software. The incidence of recurrent DVT, recurrent VTE, DVT, pulmonary embolism(PE), major bleeding, clinical relevant non-major bleeding(CRNMB) and all-cause mortality after the treatment were compared and the results were presented with risk ratio (RR) with 95% confidence interval (CI). RESULTS: Total 5 RCTs of 4 737 cases were included in this study, including 1 605 cases accepted rivaroxaban (treatment group), other of 3 132 cases accepted other drugs (control group). The results of Meta-analysis were as follows the incidence of recurrent DVT in the rivaroxaban group was lower than that in the unfractionated heparin/low molecular heparin+ vitamin K antagonists (UFH/LMWH+VKA) group (P=0.002). There was no significant difference in the incidence of pulmonary embolism, venous thromboembolism, major bleeding, CRNMB and all-cause mortality between the treatment and control group (P>0.05). CONCLUSION: In the treatment of DVT, rivaroxban shows better efficacy than that of traditional anticoagulant therapy (UFH/LMWH+VKA) and it will not increase the risk of adverse events such as bleeding and death.

Methods: A total of 299 patients were enrolled in the study from January 2012 to December 2014 and randomly divided into two groups. The control group received 5000IU low molecular heparin after the operation for 7 days and the trial group received 3 000u heparin additionally through free arterial end and venous terminal during the operation. The thrombosis formation rate and adverse drug reactions ( ADR ) of one week and 4 weeks after the operation were observed in the two groups. Results:One week after the operation, the thrombosis formation rate in the control group and the trial group was 3. 4% and 0, respectively, and four week after the operation, that was 4. 8% and 0. 67%, respectively. The incidence of ADR showed no statistical-ly difference between the two groups (P>0. 05), and no severe ADR appeared in both groups. Conclusion:Heparin combined with low molecular heparin may be more effective and safer in the prevention of primary thrombosis in the patients after AVF.
