ObjectiveTo study the effect of Shuanglong pill on expression of vascular endothelial growth factor(VEGF) and basic fibroblast growth factor(bFGF) on aortic atherosclerotic plaque.MethodsAs atherosclerotic(AS) models of rabbits were made by immune injury plus hyperlipid diet, all rabbits were divided into blank control group(group Ⅰ,6), experimental control group(group Ⅱ, 6), captopril control group(group Ⅲ, 6; 10 mg/kg·d,12 weeks), and Shuanglong pill group(group Ⅳ, 6; 2.52 g/kg·d,12 weeks). Quantitive and qualitative analysis of expression of VEGF and BFGF on aortic atherosclerotic plaque were performed.ResultsExpressive area, density and density index of VEGF and bFGF on aortic atherosclerotic plaques were significantly decreased in group Ⅲ and Ⅳ than in group Ⅱ(P<0.01). There were significant decrease for VEGF expression in group Ⅳ than in group Ⅲ(P<0.01).Pathologic staining showed that there were no foam cells formation and no stained yellow in group Ⅰ, but mass foam cells formation and widespread stained yellow in group Ⅱ. There were a small quantity of foam cells formation and little stained yellow in group Ⅲ and group Ⅳ.ConclusionShuanglong pill can delay/reverse AS progression by inhibiting VEGF and bFGF expression in atherosclerotic plaque as well as captopril.

ObjectiveTo explore the effect of Shuanglong pill which can vivid blood and relax thread pulse on cardial morphology and haemodynamics in experimental myocardial infarction (MI) rats.Methods66 rats ligated left coronary artery were randomly divided into large dose group of Shuanglong pill (LDG), small dose group of Shuanglong pill (SDG), the normal control (NC) and the control group of MI. Half in each group received 2 week treatment and the other received 4 week treatment, and were spiled in femoral and common carotid artery respectively. Parameters of cardiac haemodynamics were monitored by eight lead physiological recorder. ResultsLeft ventricular systolic maximum velocity in LDG, SDG and DC was more significantly elevated than in MI, after 2 weeks and 4 weeks of treatment, but it was lower than NC. There were no significant differences among LDG, SDG and DC. Ventricular systolic maximum velocity in LDG was more significantly elevated than in MI after 2 week treatment.ConclusionTreating MI with Shuanglong pill can improve left ventricular systolic maximum velocity, and diastolic phase function of left ventricular also elevate during the acute stage of MI by using large dose.

Based on the Bacillus sp., isolated from Lop Nur Desert, the technology of separation and purification and the antioxidant effect were studied. After centrifugation and vacuum filtration, the deproteinization of supernatant was operated with Sevag reagent. The crude exopolysaccharide (EPS) was obtained by precipitation with ethanol. The optimum conditions for the isolation were as follow: pH 7.0, temperature 4?C, time 1.5 h, and material to ethanol ratio 1: 4. Dissolved in water, the crude EPS was fractional separated on activated carbon column (1.5 cm ? 24 cm), eluted with distilled water, 60% ethanol, 95% ethanol, and the main fraction was collected. Then the EPS was purified on Sephadex G-100 gel column, eluted with NaCl (0.2 mol/L). Fractions (4 mL, each) were also combined according to total sugar by phenol-sulfuric acid method and protein content was determined by Coomassie brilliant blue. The results showed that EPS was relatively homogeneous glycoprotein. The data of antioxidation in vitro showed that the EPS had a high antioxidant activity, which could quench hydroxyl radical, superoxide radical and had antilipid peroxidation activity. All of these indicated that EPS was a good natural antioxidant.

OBJECTIVETo determine the effects of Jiji decoction (Traditional Chinese Medicine) on the cognitive function and oxidative stress in mice with vascular dementia (VD) induced by cerebral ischemia/reperfusion.
METHODSThirty-two mice were randomly divided into nonnal group (n = 8), sham group (operation, but no cerebral ischemia/reperfusi6n, n = 8), model group (vascular dementia model induced by cerebral ischemia/reperfusion, n = 8), and Jiji decoction-treated group (vascular dementia model plus treatment with Jiji decoction, n = 8). Fourteen days of treatment after operation, the cognitive behavior was measured in step-through test, spatial probe test and platform test. Afterwards, to assess the levels of oxidative stress, the activity of superoxide dismutase(SOD) and content of malonaldehyde (MDA) in brain of these mice were measured.
RESULTSData from step-through test indicated that the escaping latency of Jiji decoction-treated group was prolonged and the error counts were decreased significantly ( P <0.01) compared with those of model group. Data from spatial probe test indicated that the time of entering darkroom, the time of climbing height and the time of entering bright room in Jiji decoction-treated group were shortened and the counts of climbing height were increased (P < 0.05-0.01) significantly compared with those of model group. Data from platform test showed that the escaping latency of Jiji decoction-treated group was prolonged significantly (P < 0.01) compared with that of model group. Compared with normal and sham group, the activity of SOD was decreased and the content of MDA was increased in model group significantly (P < 0.01). Compared with those of model group, the levels of SOD and MDA in Jiji decoction-treated group were improved significantly (P < 0.01).
CONCLUSIONJiji decoction could improve cognitive function of VD mice. Its mechanism might be related with the inhibition of oxidative stiess in the brain.

Objective To discuss the coping modes for patients with chronic heart failure (CHF)dealing with their anxiety and depression; and to explore the possible way to guide effective nursing intervention aimed to reduce the patients' hospitalization rate and the length of hospitalization and to improve the quality of life for patients. Methods 120 patients with CHF were investigated by self-rating anxiety scale (SAS), selfrating depression scale and medical coping modes questionnaire (MCMQ). Results The score of patients with CHF in SAS was higher than norm model [(19.48 ± 3.81) vs (29.78 ± 10.07), t = 11. 127, P < 0. 01] and the SDS was also higher than normal model (P < 0. 01). The "facing" score of patients with CHF in MCMQ was statistically lower than that of normal model in China[(16. 08 ± 3.88) vs (19.48 ± 3.81), t = 2. 046, P <0. 05]; Both of the scores on "avoidance" and "surrender" were statistically higher than those of normal model (P < 0. 05 or P < 0. 01). Conclusions Most patients with CHF had the problems involving anxiety, depression and ineffective coping mode; patients' quality of life could be improved when their negative emotion released and their coping mode improved.

This paper introduces the surface modification of NiTi alloy intravascular stents for roughness by chemical erosion and plasma deposition technology. The stent which had been granulated with chemical erosion was treated with TiO2 film prepared with Gel-sol. The study on the biocompatibility of the modified stent by the above two ways shows that the modified stent is rougher, and its anticoagulation and hydrophilicity are improved. However, the capability of erosion resistance is not enhanced significantly.
