A large number of laboratory and clinical researches have indicated that the occurrence of restenosis after percutaneous transluminal angioplasty is mainly related to the following factors: the inflammatory reaction, the injury of vascular wall, the aggregation of platelet, the formation of thrombus, the hyperplasia of vascular endotheliocyte, etc. The corresponding parameters related to the above mentioned factors can be regarded as the clinical predictors of restenosis after pereutaneous transluminal angioplasty. This paper aims to make a summarization of some kinds of clinical predictors which are related to inflammation.

To evaluate the clinical characteristics of percutaneous coronary interventional (PCI) treatment in patients with chronic renal insufficiency, 116 patients with serum creatinine ≥141?mol/L and 352 patients who had normal serum creatinine level were included for the stady. It was found that the ineidences of using alcohol, acute myocardial infarction, hypertension, diabetes mellitus, as well as hospital stay days after PCI and the entire hospital stay days, and mean number of diseased vessels were significantly higher in renal insufficiency group compared with the control group. On the other hand, the value for HDL, the time for PCI operation, and the dose of contrast medium were lower in renal insufficiency group than in control group. The results suggested that patients with renal insufficiency were able to tolerate PCI if proper peri-operative care was observed, though they had more predisposing factors of arteriosclerosis.

Objective: To study the clinical features and angiographic findings of moyamoya disease (MMD) as well as their relationship. Methods: A total of 22 MMD patients received routine digital substraction angiography (DSA). The clinical manifestations and angiographic findings were analyzed. Results: Clinical manifestations varied and each patient often had multiple symptoms, including cerebral infarction in 9 patients with an average age of 23.6 (13-39 years) and cerebral hemorrhage in 7 patients with an average age of 31.2 (28-46 years). Angiographic examination found that all the diseased sides showed MMD blood vessels. The patients who received encephalo-myo-arterio-synangiosis (EMAS) had better prognosis than those without receiving the treatment. Conclusion: Cerebral infarction is frequent in children and adolescents with MMD, whereas cerebral hemorrhage is common in adults. DSA is a golden criterion for diagnosing MMD. Surgical treatment, EMAS blood supply reconstruction in particular, should be prescribed.

Objective To summarized the diseases which were demonstrated as hyperintensity lesions on high diffusion sensitive gradien(high b value) diffusion weighted imaging(DWI) To investigate the differential diagnosis of the diseases and to discuss the corresponding biophysics mechanism Methods 90 cases were studied, which were clinically highly suspected of brain ischemic stroke onset and in which hyperintensity lesions were demonstrated on DWI The patients were divided to 2 groups according to the time between the onset and the MR examination:group A(1 5-6 0 h)with 13cases, group B(7 h to 8 d)with 77cases The appearances of the lesions on conventional MRI, ADC values and anistropy(CV )of the lesions were studied Results hyperintensity lesions on high b value DWI were demonstrated in following diseases: acute ischmia, hematoma, abcesses, mengioma, mutiple sclerosis(MS) The ADC value was decreased to(5 87?1 02)(10 -4 mm 2/s in superacute cerebral ischemia, while the ADC value increased to (8 08?1 15)?10 -4 mm 2/s in active MS The CV in cerebral ischemia lesions was higher than the control group( P

AIM: To investigate the effect of fibrinogen (Fg), fibrin (Fb) and fibrin degradation products (FDPs) on the proliferation and migration of human vascular smooth muscle cells (VSMC).METHODS: The effects of Fg, Fb and FDPs on the proliferation of VSMC were observed by means of cell counting and MTT test, migration assays were performed using the wounding model and the transwell cell culture apparatus.RESULTS: Fg itself did not stimulate the proliferation of VSMC, but stimulated VSMC migration. Fb and FDPs both stimulated the proliferation and migration of VSMC, meanwhile the effect of Fb was in a dose-dependent manner.CONCLUSION: Fb, in particular FDPs, may play an important role by stimulating the proliferation and migration of VSMC in restenosis and atherogenesis.

Objective Using MRI techniques and the FreeSurfer software package to research the occipital lobe's surface area in children with ametropic amblyopia.Design Prospective,nonrandomized clinical trial.Participants The amblyopic group included 10 children with ametropic amblyopia.The control group included 10 children with normal sight.Methods The brain MRI scan was per- formed with SIEMENS AVANTO 1.5 Tesla scanner.For the surface area analysis,3-demensional MPRAGE images were analyzed with FreeSurfer software package.Main Outcome Measures Occipital lobe related surface area(cuneus,later occipital,lingual,perical- carine)of bilateral hemisphere.Results No difference was between the ages of the two groups.The surface areas of the lingual,pefical- carine,cuneus of bilateral hemisphere and lateraloccipital on the left hemisphere in amblyopic patients were smaller than those of nor- real children(P
