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 analyze the characteristics of pulse pressure index(PPI) and its value in predicting the risk for cerebral and cardiac vascular events in old males with hypertension. Meth-ods The 24-hours ambulatory blood pressure monitoring was performed in a total of 265 elderly men with essential hypertension(EH). The patients were classified into 3 groups based on the lev-el of PPI.PPI≤0.400(103) ,0. 401-0. 500(124) ,and≥0.501(38). Results There was significant difference in PP between day-time and night-time in hypertensive patients. The change of PPI was less than that of PP. With the increase in PPI, SBP(24 h, day-time, night-time), PP(24 h, day-time, night-time), the load of SBP(night-time), systolic blood pressure variation(BPV, 24 h, day-time) were raised significantly (P<0.01); while DBP(24 h, day-time, night-time), nocturnal de-cline in BP and the load of DBP(day-time) declined with the decrease in PPI (P<0.01). High PPI would increase the incidence of cardiac-cerebral vascular events (P < 0.01). Conclusion PPI is a useful parameter in clinical evaluation of arteriosclerosis. It may also have prognostic value for cardiac-cerebral vascular events in elderly men with EH.

Objective To study the significance of serum IL-17 level in patients with acute coronary syndrome (ACS ) before and after rosuvastatin treatment .Methods Forty-eight ACS patients served as group A and 30 stable angina pectoris patients served as group B in this study .T heir blood-lipid level and serum hs-CRP and myocardial enzyme levels were measured and the number of coronary artery branches with lesions was calculated .Their association with serum IL-17 level was analyzed .Patients in group A were treated with rosuvastatin .The serum IL-17 levels were compared in two groups before and 4 weeks after rosuvastatin treatment .Results The serum IL-17 level was significantly higher in group A than in group B before rosuvastatin treatment (34.41 ± 6 .37 ng/L vs 15 .18 ± 3 .11 ng/L ,P<0 .05) and significantly lower in group A 4 weeks after rosuvastatin treatment than before rosuvastatin treatment (16 .71 ± 4 .72 ng/L vs 34 .41 ± 6.37 ng/L ,P<0 .05) .No significant difference was found in serum IL-17 level between the two groups after rosuvastatin treatment (P>0 .05) .Multivariate regression analysis showed that the serum hs-CRP and troponin level and the number of coronary artery branches with lesions were positively related with the serum IL-17 level (P=0 .012 ,0 .008 ,0 .000) .Conclusion Serum IL-17 level in ACS patients can partly reflect the severity of ACS .Early treatment of ACS with rosuvas-tatin can reduce the inflammatory reactions and serum IL-17 level ,and is of great significance in stabilizing the coronary plaques and reducing the incidence of ACS .
