Objective To assess the efficiency and safety of alendronate for the prevention and treatment of glucocorticoid-induced osteoporosis (GIOP).Methods The electronic databases of PubMed,EMBASE,Cochrane Library,Web of Science,Chinese BioMedical Literature Database (CBM) and Wanfang Data were searched for all randomized controlled trials (RCT) of alendronate vs.placebo.Two reviewers independently selected trials for inclusion,assessed trial quality using Jadad's scale and extracted the data.RevMan 5.1 software was used for data synthesis and Meta-analysis.Results Seven studies with 1111 patients were included.Compared with placebo,alendronate significantly increased bone mineral density (BMD) at the lumbar spine[MD =3.35,95%CI (2.67-4.02),P =0.000] and the femoral neck[MD =1.90,95% CI (0.89-2.92),P =0.000] after 12 months of therapy.After 24 months of therapy,alendronate significantly increascd BMD at the lumbar spine [MD =3.91,95% CI (2.37-5.45),P =0.000],but not at the femoral neck [MD =1.91,95% CI (-1.15-5.02),P =0.22].Compared with placebo,no significant reduction was found by the use of alendronate in the incidence of vertebral fractures [RR =1.00,95% CI (0.49-2.07),P =0.99] or nonvertebral fractures[RR = 1.02,95% CI (0.49-2.14),P =0.95].No difference was shown with the adverse event between the two groups[RR =0.97,95% CI (0.90-1.05),P =0.47].Conclusions Alendronate is effective for the prevention and treatment of glucocorticoid-induced bone loss at the lumbar spine and the femoral neck with relatively good safety profile.Yet,there is no significant difference between the two groups in reducing the incidence of vertebral fractures and non-vertebral fractures.Large-scale RCT designed to observe whether different lengths of alendronate therapy will influence the efficiency should be conducted in the future and to further explore whether it can reduce the incidence of fractures.

Objective To study the clinical efficacy of intra-arterial thrombolysis with recombinant tissue plasminogen activator (rt-PA) for the treatment of ischemic cerebrovascular disease caused by cerebral thrombosis. Methods A total of 245 patients accepted by our hospital during May 2013 and July 2015 were divided into the observation group (n=148) and the control group (n=97). All patients were given conventional process for controling blood pressure and blood lipids. Patients in observation group received intra-arterial thrombolysis with rt-PA, while patients in control group accepted conventional treatment. At the time of admission, the demographic characteristic, vascular influencing factors, baseline clinical findings, laboratory findings and neurological deficits were collected. The improvement of neurological function was evaluated by the modified Rankin scale 3 months after treatment. The levels of fibrinogen (FIB), D-Dimer, activated partial thromboplastin time (APTT) and thrombin time (PT) were measured before and 24 h after the treatment. Results There were no significant differences in demographic characteristic and general clinical data between the two groups ( P>0.05). The proportion of patients with improved neurological function was significantly higher in observation group than that of the control group (83.11%vs. 53.61%, P<0.05). There were no significant difference in coagulation index and fibrinolysis index before treatment between the two groups (P>0.05). Twenty-four hours after the treatment, the levels of FIB, D-Dimer, APTT and PT were significantly improved in the observation group compared with those before treatment. The level of FIB was significantly decreased, D-Dimer was significantly increased, APTT and PT were significantly prolonged in observation group compared with those of control group (P<0.05). Conclusion The rt-PA can effectively dissolve thrombosis and correct the coagulation system and fibrinolytic system.
