ABSTRACT
BACKGROUND: Oxfordshire Community Stroke Project(OCSP) is a new type of clinical classification for subdividing cerebral infarction(CI) conducted on the basis of a large-scale of investigation of stroke in the population of Oxfordshire Community, England in 1991. This kind of classification completely bases on the clinical manifestations without the help of diagnostic instruments, which can predict site and size of the lesion and the involved vessels.OBJECTIVE: To acknowledge the clinical classification of CI patients with Bamford's OCSP and its significance in predicting their long-term functional prognosis.DESIGN: Clinical observation, comparison and verified study based on patients.SETTING: Neurological department in a university hospital.PARTICIPANTS: Between January 1st and December 31st 2001, totally 126 patients with cerebrovascular disease were hospitalized in the Neurological Department of First Affiliated Hospital of Xi' an Jiaotong University,including 82 males and 44 females.METHODS: Totally 126 in-patients with CI were subdivided with Bamford's OCSP classification, and their disablity was assessed with Barthel index (BI)and modified Rankin Scale(mRS) when they were discharged and 3 months and 6 months later.MAIN OUTCOME MEASURES: Classification of patients with CI and their scores of BI and mRS when they were discharged and 3 months and 6months later.RESULTS: Of the 126 patients, 8(6. 3% ) patients were confirmed of total anterior circulation infarction (TACI), 29 (23. 0% ) of part anterior circulation infarction(PACI), 78(61.9% ) of lacunar infarction(LACI), 11(8.7%) of posterior circulation infarction(POCI) . They were followed-up for 6 months, and meanwhile 12 patients died. Of the other 114 cases the prognosis of TACI was the worst, while the prognosis of POCI and LACI was relatively better than that of PACI.CONCLUSION: CI is predominated by LACI. OCSP is effective for predicting long-term functional prognosis of patients with CI. But it is necessary to make multi-center prospective study on a much larger scale of samples of disease.
ABSTRACT
Objective To analyse the levels of estrogen in women patients with Alzheimer's disease(AD),and the relationship of estrogen level,menarche age,age of menopause,pregnancy times with severity of AD.Methods A 1:1 matched case-control study was conducted.The study subjects were given neuropsychological test face to face in questionnaire,including MMSE,ADL,POD,FOM,WISE and HMT depression scale.All the women subjects accepted another questionnaire concerning menarche age,age of menopause and pregnancy times.Radioimmunoassay was used to measure the sex hormone level of all the subjects.Results The level of estrogen in serum was obviously lower in AD group than in the control group(P
