The association of plasma tissue type plasmingogen activator (t-PA) and plasminogen activator inhibitor (PAI-1) with carotid atherosclerosis in patients with type 2 diabetes was explored.The subjects with type 2 diabetes (n =91) and control subjects (n =30) were enrolled for this study.According to carotid artery intima media thickness in Color Doppler Ultrasonography,the subjects with type 2 diabetes were divided into four groups:normal carotid group(group 1,n =25),lining thickening group (group 2,n =30),stable plaques group (group 3,n =23),carotid stenosis group(group 4,n =13).Plasma t-PA and PAI-1 levels were measured by ELISA.Compared with the control group,there was no significant change in the levels of plasma t-PA and PAI-1 in group 1 (P＞0.05),plasma t-PA activity was decreased significantly(P＜0.05) and PAI-1 activity increased obviously (P＜0.05) in group 2,group 3,and group 4.Carotid atherosclerosis degree was negatively correlated with t-PA(r=-0.723,P＜0.01) and positively correlated with PAI-1 (r=0.851,P＜0.01).The results suggested that the abnormal fibrinolysis function may take part in the development of atherosclerosis of carotid arteries in patients with type 2 diabetes.

Objective To evaluate clinical efficacy and safety of levornidazole in the treatment of pelvic anaerobic infections. Methods A multicenter randomized controlled clinical study was conducted to evaluate clinical efficacy and safety of levornidazole. One hundred and fourty-three patients with pelvic anaerobic bacteria infection were classified into 70 cases treated by levornidazole in study group and 73 cases treated by Ornidazole in control group. Those patients in two groups were both administered at a dose of 0. 5 g twice daily for 5 - 7 days. The rate of clinical efficacy, bacteria clearance and adverse effect were recorded and compared between two groups. Results At the endpoint, the rate of clinical efficacy were 80% (56/70) in study group and 81% (59/73) in control group, which did not reach significant difference (P＞0. 05). The rate of bacteria clearance were 97% (36/37) in study group and 92% (22/24) in control group, which also did not reach significant difference(P ＞0. 05). The rate of adverse reaction of 3% (20/70) in study group was significantly lower than 22% ( 16/73 ) in control group ( P ＜ 0. 05 ). Conclusion It is effective and safe to treat pelvic anaerobic infections with levornidazole and sodium chloride injection.
