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 study the impact and mechanism of continuous venovenous hemofiltration (CVVH) in different uhrafihration rates on plasma cytokines in porcine endotoxemic shock. Methods Eighteen anesthetized mechanically ventilated pigs weighing 21-34 kg were randomly divided into three groups. In control group (n=6), the pigs received a 15.7 μg/kg endotoxin (E.coli 0111:84) infusion. In CVVH group (n=6) and high volume hemofihration (HVHF) group (n=6), the pigs received CVVH after the endotoxin infusion for 24 hours with an was taken before endotoxin infusion and at 0, 1, 6, 12, 24 h during CVVH. The plasma levels of TNF-α, IL-6, IL-10 and IL-18 were tested by ELISA. Results The survival time in control group was (15.4±5.2) h,CVVH group was (21.4±7.1) h,HVHF group was (22.4±6.7) h. The survival time in CVVH and HVHF group was significantly longer than that of control group (P< 0.05 ). Heart rate (HR), mean arterial blood pressure (MAP), central venous pressure (CVP) and cardiac output (CO) showed no significant differences among three groups. Plasma BUN and Ser increased gradually after the establishment of porcine endotoxemic shock model. BUN and Scr of CVVH and HVHF group were lower compared to control group (P<0.05), but there was no significant difference between CVVH and HVHF group (P>0.05). Plasma TNF-α and IL-6 peaked at T1, IL-10 peaked at TO, then they declined gradually. While IL-18 increased at TO and did not change after TO. A significant decrease of plasma IL-10 level was observed at T6, T12 and T24 in CVVH group compared with control group (P<0.05). HVHF group accomplished a greater decrease in plasma TNF-α (T6) and IL-10 (T6, T12, T24) levels compared with control group and CVVH group (P< 0.05). The levels of IL-6 and IL-18 showed no significant differences among three groups. There was a negative correlation between IL-6 and survival time (P<0.05). Conclusions HVHF and CVVH can prolong the survival time of porcine endotoxemic shock. IL-10 can be removed effectively with CVVH and HVHF. HVHF can also remove TNF-α effectively. CVVH and HVHF treatment can both remove BUN and Scr effectively. IL-6 is a powerful independent predictive factor for survival time of porcine endotoxemic shock.

Objective To analyze the expression and regulation of components of intrarenal renin-angiotensin system (RAS) and the correlation between intrarenal angiotensin Ⅱ (Ang Ⅱ) expression and clinicopathological injury index in primary IgA nephropathy patients. Methods Expressions of intrarenal RAS components were assessed by immunohistochemistry staining (IHCS). Correlation among intrarenal RAS components and of intrarenal Ang Ⅱ expression with blood pressure, estimated glomerular filtration rate (eGFR), 24-h urinary protein and Katafuchi score in 36 primary IgA nephropathy patients were examined. Results There were positive correlations between positive IHCS area of intrarenal renin and Ang Ⅱ (r=0.43, P＜0.01), angiotensiongen and Ang Ⅱ (r=0.34, P＜0.05). There was negative correlation between positive IHCS area of intrarenal Ang Ⅱ and eGFR (r=-0.61, P＜0.01). There was positive correlation between positive IHCS area of intrarenal Ang Ⅱ and pathological chronicity index (ρ=0.39, P＜0.05), index of interstitial cell infiltration (ρ =0.52, P ＜0.05). Conclusion Expression of intrarenal Ang Ⅱ is positively correlated with expression of intrarenal renin and angiotensinogen, and plays an important role in kidney fibrosis in primary IgA nephropathy.

Objective To analyze the correlation of urinary angiotensinogen (AGT) with clinical index of kidney injury and intrarenal renin-angiotensin system (RAS) activity in chronic kidney disease (CKD) patients. Methods Urinary or plasma renin activity, AGT, angiotensin Ⅱ (Ang Ⅱ ), aldosterone were measured by RIA or ELISA in 129 CKD patients. Expression of intrarenal renin, AGT, Ang Ⅱ and angiotensinⅡ receptor was examined by immunohistochemistry staining (IHCS) in 73 CKD patients undergoing renal biopsy. Correlation of urinary AGT with other indexes was performed. Results Average urinary AGT in 129 CKD patients was (159.08 ± 125.18) μg/g Cr, Scr was (113.20± 105.05)μmol/L, and urinary AGT was positively correlated with Scr (r=0.51, P<0.01). Average estimated glomerular filtration rate (eGFR) was (58.52±27.15) ml·min-1·(1.73 m2)-1, which was negatively correlated with urinary AGT (r=-0.55, P<0.01). Average urinary protein was (2.03±2.65) g/24 h, which was positively correlated with urinary AGT (r=0.30, P<0.01). Average urinary Ang Ⅱ was (164.71 ±139.25) ng/g Cr, which was positively correlated with urinary AGT (r=0.20, P<0.05). Average urinary type Ⅳ collagen was (447.60± 800.66) μg/g Cr, which was positively correlated with urinary AGT (r=0.47, P<0.01). Average urinary soduim was (162.17±81.61) mmol/24 h, which was negatively correlated with urinary AGT (r=-0.20, P<0.05). Multiple regression analysis indicated that low eGFR (P<0.01), high Scr (P< 0.01), high urinary protein (P<0.05), high urinary Ang Ⅱ (P<0.05) and high urinary type Ⅲ collagen (P<0.01) were significantly correlated with high urinary AGT. In renal tissues of CKD patients, there was positive correlation of urinary AGT with positive IHCS area of AGT (r=0.45, P< 0.01), Ang Ⅱ (r=0.52, P<0.01) and angiotensin Ⅱ type 1 receptor (r =0.28, P <0.05). Conclusions Urinary AGT level may indicate the kidney injury severity, especially in chronic kidney injury, and may be used as a non-invasive marker of intrarenal Ang Ⅱ activity in CKD patients.

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
