Objective To investigate the relative factors of vascular parkinsonism(VP),in order to provide a clinical basis for early diagnosis of VP. Methods The method of prospective cohort study was used. The first cerebral infarction was taken as the initiating event. All the cases were followed up for 4 years. When they suffered from VP or died of VP, the follow-up was termina-ted. Logistic regression model was used to analyze the risk factors for VP. Results Fifty-four pa-tients developed VP in 404 patients with first cerebral infarction,the incidence rate was 13.4%.According to the typing standard of OCSP,in the 404 patients, the incidence of VP was highest in lacunar infarction group(42 cases, 20.4%). The main risk factors for VP included age (P=0.043, OR = 1. 135,95% CI: 1. 010-1. 275),hypertension history (P=0.032, OR=2.019,95% CI: 1.247-4.746), blood viscosity (P=0.041, OR=1.724,95% CI: 1.036-3.058) and fibrinogen (P=0.001, OR=2.241,95% CI: 1.272-5.473). Conclusion During follow-up for 4 years,the incidence rate of VP in patients with first cerebral infarction is 13.4%. Lacunar in-farction is apt to cause occurrence of VP. Age, hypertension history, blood viscosity and fibrinogen are risk factors for VP. VP may be caused by multiple factors and multiple mechanisms.

Objective To investigate the effects of surgery-induced menopause on neuropsychological symptoms in women with perimenopause. Methods Sixty-eight women with perimenopause who underwent bilateral oophorectomy for benign indications were evaluated by the modified Kupperman index on the perimenopause syndrome pre-and post-surgery,including the score in neuropsychological symptoms.Patients were further requested to remake a decision on the acceptance of surgery,and were divided into "accept the surgery" group(n=30) and "postpone the surgery" group(n=38).The neuropsychological symptoms were reevaluated and comparison was made between these two groups. Results The prevalence of perimenopause syndrome pre-surgery was 67.65%(22/68),and that of moderate and severe symptoms was 30.88%.The prevalence of perimenopause syndrome post-surery(97.06%)(66/68)was significantly increased,as well as that of moderate and severe symptoms(70.59%)(P

Objective To compare the clinical diagnostic value of 320 row four-dimensional CT angiography (4D-CTA)and digital subtraction angiography (DSA)in untreated arteriovenous malformation (AVM)patients.Methods Thirty-six patients with AVM diagnosed by DSA were included in this study.Two independent readers blind to the results of all examinations evaluated the find-ings of DSA and 4D-CTA of each patient.All results were then documented using a standardized scoring sheet.Results The diagno-sis results of 4D-CTA for AVM lesions in all 36 patients were accurately consistent with those of DSA,including the position,size and vascular structure.There were 14 cases with the largest diameter <3 cm,20 cases 3-6 cm,2 cases >6 cm.Lesions involved only the anterior circulation in 13 cases,only the posterior circulation in 13 cases,and both the anterior and posterior circulation in 10 cases.Conclusion 4D CTA has excellent diagnostic accuracy in the detection of AVM lesions,including size,location,feeding ar-teries and draining veins,with similar value as DSA in the clinical diagnose and evaluation of AVM.

Objective To determine the role of nuclear factor-?B(NF-?B) in ischemic acute renal failure (ARF) rats. Methods Gel mobility shift assay was used to detect the DNA binding activity of NF-KB in ischemic ARF rats and reverse transcription-polymerase chain reaction (RT-PCR) assay was used to study the expression of renal inducible nitric oxide synthase (iNOS) . The relationship between DNA binding activity of NF-?B and expression of iNOS was also analyzed. Results The DNA binding activity of NF-?B in renal cortex increased from 1.00 ?0.17 of controls to 3. 67 ? 1. 94 of 6 hours after ischemia-reperfusion ( P

OBJECTIVE To study the changes in air bacteria content under gradual circuit model and ordinary circuit model in operating room.METHODS Altogether 80 cases with thyroid gland surgery and gastrointestinal surgery were selected,and divided them randomly into two groups: the gradual circuit model and the ordinary circuit model,each group had 40 cases.The period of early morning to the end of operation was divided into 10 time spots to carry on the air bacilliculture.RESULTS Under the ordinary circuit model,air colony showed straight up with time during the two types of surgical operations,and there was no significant difference between the two types of surgery.Under the gradual circuit model,air colony began to increase with time,followed by steady,or even decline,no differences between the two types of surgery. Roving between two models,significant statistical difference emerged in thyroid surgery from the 30-minutes of operation(P

Objective To investigate the anti-HBV constituents from Alternanthera philoxeroides.Methods The constituents were isolated with silica gel and gel permeation chromatography,and purified by HPLC.Their structures were elucidated by spectroscopy.The antivirus effects of the isolated compounds were tested by ELISA method in vitro.Results Ten compounds were isolated and elucidated as followings:oleanolic acid(Ⅰ),oleanolic acid 3-O-?-D-glucuronopyranoside(Ⅱ),oleanolic acid 28-O-?-D-glucopyranoside(Ⅲ),chikusetsusaponin Ⅳ a methyl ester(Ⅳ),4,5-dihydroblumenol(Ⅴ),N-trans-feruloyl 3-methyldopamine(Ⅵ),N-trans-feruloyl tyramine(Ⅶ),3?-hydroxystigmast-5-en-7-one(Ⅷ),24-methylenecycloartanol(Ⅸ),and cycloeucalenol(Ⅹ).The values of inhibition percent of compounds Ⅰ-Ⅲ,Ⅴ-Ⅶ revealed a significant distinction compared to the control group.Compounds Ⅱ and Ⅴ showed significant inhibition against HepG2 cells transected with cloned hepatitis B virus DNA,their inhibitive ratios were 85.38% and 87.37% at 50 ?g/mL,respectively.Conclusion Compounds Ⅳ-Ⅶ are isolated from this plant for the first time and phenolic amides have been determined as the new structure type from the plants of Alternanthera Forsk.Compounds Ⅱ and Ⅴ from A.philoxeroides show the more significant anti-HBV activities.
