OBJECTIVE:To investigate the current situation of anticoagulant therapy for patients with non-valvular atrial fibril-lation,and to provide reference for standardized anticoagulant therapy. METHODS:A total of 1056 patients with non-valvular atri-al fibrillation were collected from our hospital during Jul. 2015-Jun. 2016. According to 2012 European Society of Cardiology Guide-lines for the Management of Atrial Fibrillation,the risks of thrombosis and hemorrhage were evaluated,and the standardized anti-coagulant therapy was also evaluated. RESULTS:Among 1056 patients with non-valvular atrial fibrillation,the number of patients with thrombosis risk score ≥1 was 1028,accounting for 97.3%. 763 patients received antithrombosis therapy,and only 139 pa-tients were given warfarin anticoagulant therapy. The international normalized ratio(INR)of prothrombin time in just 30.9% of pa-tients receiving warfarin was in line with the standard before discharge. CONCLUSIONS:The anticoagulant therapy for patients with non-valvular atrial fibrillation is still not optimistic,and effective measure should be adopted to improve the standardization of anticoagulant therapy in the patients with atrial fibrillation.

Objective To investigate the protective effect of glutamine(Gln) pretreatment on intestinal ischemia-reperfusion (I/R) injury and endothelial nitric oxide synthase (eNOS)/nitric oxide (NO) signaling pathway in rat model. Methods Thirty male Wistar rats were randomly divided into three groups(n=10 for each group):sham group, I/R group and Gln group. Animals were pretreated with 1 g/(kg·d)Gln by orogastric route for 7 days in Gln group, and normal saline was given to the other two groups in the same dose. Intestinal I/R was induced by 30 min occlusion of the superior mesenteric artery followed by 24 h of reperfusion. After the operation, the intestinal histopathological changes, the plasma endotoxin level, serum D-lactic acid, eNOS, inducible NOS(iNOS)activity and NO levels were detected by ultraviolet spectrophotometer. The mRNA expressions of myocardial eNOS and iNOS were detected by real-time fluorescence quantitative PCR (RT-PCR). Results After reperfusion, in IR group, extensive epithelial sloughing and mucosal ulceration of villous tips were observed, whereas these findings did not occur in Gln group and sham group. Compared with IR group, the serum NO, eNOS levels and eNOS mRNA expression of intestinal tissue were elevated in Gln group (P<0.01), but the plasma endotoxin level, serum D-lactic acid, serum iNOS and intestinal iNOS mRNA expression decreased in IR group(P<0.05). Conclusion Glutamine pretreatment has protective effects on intestinal ischemia-reperfusion injury in vivo. The mechanism may be related to the inhibition of iNOS expression and the increased expression of eNOS, thereby increasing NO activity.

Objective:To study the effect of shear stress on the expression of KLF2 and eNOS in venous endothelial cells under physiological and uremic conditions, and to explore the mechanism leading to dysfunction of venous endothelial cells.Methods:Under physiological conditions and uremia conditions, different shear stresses were simulated in the parallel plate flow cavity, and the shear stresses were applied to the venous endothelial cells of each group for 4, 12, and 24 hours. The expression of KLF2 and eNOS was detected by immunohistochemical fluorescent staining technique and real-time fluorescent quantitative PCR technique.Results:Under physiological conditions, KLF2 is obviously regulated by shear stresses. High-intensity shear stresses and physiological shear stresses will up-regulate the expression of KLF2, while low-intensity shear stresses and oscillating shear stresses will down-regulate the expression of KLF2. As the duration of action increases, the expression of KLF2 will also increase. In the state of uremia, the expression of KLF2 is significantly inhibited. Even if high shear stresses is applied, the level of KLF2 is not high-expressed as the physiological state. And under the action of low shear stresses and oscillating shear stresses, KLF2 expression is more significantly inhibited. KLF2 is mainly expressed in the nucleus. With the action of shear stresses, KLF2 is also expressed in the cytoplasm, while eNOS is mainly expressed in granular form in the cytoplasm and nucleus.Conclusions:After arteriovenous fistula operation, the expression of KLF2 and eNOS is inhibited under the action of multiple factors of uremia environment and oscillating shear stresses, which may be the main cause of the occurrence and development of venous endothelial cell dysfunction, intimal hyperplasia, and AVF failure.
