ObjectiveTo evaluate the safety and superiority of dressings and bandage compression method for patients after percutaneous coronary intervention through femoral artery.MethodsA total of 648 patients who received percutaneous coronary intervention through femoral artery were randomly divided into three groups: the modified group (224 cases), the routine group (213 cases) and the haemostat group (211 cases), they each adopted modified dressings and bandage compression method, the traditional oppression hemostatic method, and arterial oppression with hemostat method. The unarmed oppression time, expenditure, braking time, and complications were observed and analyzed statistically.ResultsThere was no significant difference in braking time and local vascular complications of the three groups. Compared with the routine group, the modified group reduced the unarmed oppression time and the medical staffs workload; compared with the hemostat group, it reduced the expenditure.ConclusionsImproved dressings and bandage compression method can reduce the unarmed oppression time and expenditure, it is an ideal local hemostasis method for patients undergoing percutaneous coronary intervention through femoral artery, and is worthy of clinical application.

Objective To observe the effect of basic fibroblast growth factor (bFGF) on magnetic resonance spectroscopy of vascular dementia (VD) rats.Methods After the VD model was reproduced, the 12 rats were randomly divided into the therapy group and dementia group with 6 animals in each group. Another 6 rats were selected as sham operation group. The VD rats in therapy group were treated with bFGF by hypodermic injection. After 5 weeks, abilities of learning and memory of three groups' rats were tested by Morris water maze. The changes of magnetic resonance spectroscopy and N-acetyl aspartate (NAA), NAA/（Cr＋Cho） in lobus temporalis of VD rats were also observed.Results Abilities of learning and memory of rats significantly improved in the therapy group than that in the dementia group (P<0.01). The values of NAA, NAA/（Cr＋Cho） in lobus temporalis of VD rats significantly increased in the therapy group than that in the dementia group (P<0.01).Conclusion bFGF by hypodermic injection can obviously elevate abilities of learning and memory and the values of NAA, NAA/（Cr＋Cho） in lobus temporalis of VD rats.
