This study is designed to explore the possible effects of Hemerocallis citrina baroni flavonids (HCBF) on liver fibrosis induced by CCl4 in rats. The liver fibrosis model was induced by CCl4, and HCBF were administered by gastric perfusion at 25 and 50 mg x kg(-1) qd for 50 days, while the contents of alanine transaminase (ALT), aspartate aminotransferase (AST), gamma glutamyl transpeptidase (GGT), alkaline phosphatase (ALP), superoxide dismutase (SOD), maleic dialdehyde (MDA) and transforming growth factor-β1 (TGF-β1) were measured and the contents of PINP were measured in liver tissue, and the expression of TGF-β1 were observed by immunohistochemisty and Western blot. The pathological changes of liver tissue were examined by HE. The results showed that HCBF (25, 50 mg x kg(-1)) improved the liver function significantly through reducing the level of ALT, AST, GGT and ALP (P < 0.05 or P < 0.01), and increasing the content of SOD (P < 0.01), while reducing the content of MDA (P < 0.05 or P < 0.01), the expression of TGF-β1 (P < 0.05) and the content of PINP (P < 0.05). The results suggest that HCBF (25, 50 mg x kg(-1)) may inhibit the liver injury induced by CCl4 by decreasing the oxidative stress.

BACKGROUND:The risk of lower extremity deep venous thrombosis was high in patients with bone metastases. Major surgery is a major risk factor for thrombosis. There was no standard prophylactic regimen available.
OBJECTIVE:To investigate the efficacy and safety of low molecular weight heparins versus rivaroxaban in the postoperative prevention of lower extremity deep venous thrombosis in patients with bone metastases.
METHODS:From January 2010 to December 2013, a total of 73 patients with bone metastasis in spine, pelvis and lower extremities, who underwent open surgery in the Department of Musculoskeletal Tumor, Third Hospital, Hebei Medical University, China, were retrospectively analyzed. The patients were divided into low molecular weight heparins group (n=41) and rivaroxaban group (n=32) according to the prophylactic drugs after surgery.
RESULTS AND CONCLUSION:Nine cases (22%) in the low molecular weight heparins group were found lower extremity deep venous thrombosis, and six cases (19%) in the rivaroxaban group suffered from lower extremity deep venous thrombosis, showing no significant differences (χ2=0.11, P=0.74). The incidences of bleeding events in both groups were respectively 7.32%and 6.25%, showing no significant differences (correctionχ2=0.083, P>0.05). There were no significant differences regarding the levels of platelet, activated partial thromboplastin time and prothrombin time between both groups preoperatively or postoperatively (P>0.05). Therefore, the efficacy and safety of low molecular weight heparins and rivaroxaban in the postoperative prevention of lower extremity deep venous thrombosis were similar. Both could effectively reduce the incidence of deep venous thrombosis, with a relative low risk of bleeding.
