AIM protective effects of the Marine Face Pack (MFP) on hairless mice damaged by ultraviolet B(UVB) and it's relation to antioxidants were studied. MATHODS oxidative damage models of hairless mice irradiated by ultraviolet B (radiating intension; UVB 5. 15 ? 10-2J/cm2 ? 30 day) were established. The mice were randomly divided into four groups: control, UVB radiated groups (Water model, 10%MFP, 10%VitC). The ultrastructures of skin were observed by electromicroscope. The expression of Bcl - 2 protein and NOS were examined by immunohistochemical methods. The contents of MDA, the activities of GSH-Px, SOD and the T-AOC in the supernates of skin of those mice were detected by biochemical methods. RESULTS The large dilatant vacuolations and few rough endoplasmic reticu-lum in fibroblasts and epidermic cells of mice in UVB model group were observed under electromicroscope. MFP could keep the ultrastructure of epidermis and fibroblasts in the mice of MFP groups normal. MFP could enhance the expression of Bcl-2 protein and inhibit the ac-tivitiy of NOS(P

Objective To observe the effects of grape seed proanthocyanidin extract(GSPE) plus atorvastatin treatment on matrix metalloproteinase-9 ( MMP-9) in experimental atherosclerosis rabbits and to explore its mechanism. Methods Thirty male New Zealand rabbits were randomized into five groups. The normal control group were fed with standard diet for 24 weeks. And the other groups were fed with standard diet containing 1 % cholesterol for 12 weeks. In the sequential 12 weeks, the model control group was fed with standard diet. The GSPE group was fed with standard diet containing 1% grape seed proanthocyanidin(GSP). The atorvastatin group was fed with standard diet containing atorvastatin(2. 5 mg · kg~(-1) · d~(-1)). The GSPE plus atorvastatin group was fed with standard diet containing 1% GSP and atorvastatin (2. 5 mg~(-1) · kg~(-1) · d~(-1)). Blood samples were drawn from ear middle arteries of rabbits just before the experiment and at the 12th and the 24th weekend of the experiment. All the rabbits were fasted for at least eight hours before the blood was drawn. The blood samples were analyzed for the matrix metalloproteinase-9 (MMP-9). All the rabbits were sacrificed at the 24th weekend, and the expression of MMP-9 was observed in the thoracic aortic tissue using immunohistochemistry technique. Results The serum level and aorta expression of MMP-9 were increased in model group compared to control group (all P< 0. 05). The severity of atherosclerosis was less in three drug groups than that in model control group. The GSPE,atorvastatin and GSPE plus atorvastatin groups versus model group showed less atherosclerotic lession, the decreased expression of aorta MMP-9 and the decreased serum level of MMP-9 C(1. 06±0. 21), ( 1. 07 ±0.20), (0.81 + 0.16) vs. (1. 32±0. 24)ng/ml,all P<0. 05]. The effect in the GSPE and atorvastatin group was most obvious. Conclusions GSPE plus atorvastatin group has the most efficacy of anti-atherogenesis, which is associated with its reducing the expression of matrix metalloproteinase.

Objective To explore the relationship between morphological features of carotid arterial atherosclerosis plaque and various cardiovascular risk factors in the aged.Methods The 321patients who underwent cerebral angiography were classified into two groups:256 patients with carotid arterial atherosclerosis and 65 patients without plaque.The relationships between carotid arterial plaque and cardiovascular risk factors including age,gender,cholesterol(TC),triglyceride (TG),high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol(LDL-C),C-reactive protein(CRP),homocysteine (HCY),hypertension,diabetes,smoking and drinking were analyzed.The relationships between morphological features,including the stenosis degree,surface fairing of plaque,and cardiovascular risk factors were analyzed.After 1 year follow-up,the prospective cardiovascular and cerebrovascular events were analyzed in the two groups.Results Carotid atherosclerosis was connected with cardiovascular risk factors such as TC,LDL-C,uric acid,CRP,hypertension,diabetes,smoking and drinking.Positive correlation was showed between the stenosis degree of carotid artery and age,smoking and diabetes.Closely correlation was showed between surface fairing of carotid arterial plaque and LDL-C,CRP,smoking and diabetes.The stenosis degree of carotid artery only showed positive correlation with cerebrovascular events,but the morphological features of surface fairing of carotid arterial plaque equally showed positive correlations with cerebrovascular events and cardiovascular events.Conclusions The development of carotid arterial atherosclerosis plaque in the aged is closely related to cardiovascular risk factors.Morphological features of carotid arterial plaque may respond the level of general atherosclerosis better than stenosis degree,and it is also in close correlation with cerebrovascular events and cardiovascular events.

Objective To investigate the association between carotid-femoral pulse wave velocity (cfPWV) and composition of the ascending aorta in patients with coronary heart disease (CAD),Methods The study population comprised 60 consecutive CAD patients who underwent coronary artery bypass graft (CABG) surgery in Qilu Hospital of Shandong University.cfPWV vas measured using an automatic device (Complior,Artech,France).A quantitative study was conducted on ascending aorta specimens by histological observation (Masson staining and weigert's resorcin-fuchsin staining) and computer image analysis.Bivariate analyses were performed to study the association between composition of the ascending aortic media and cfPWV.Results cfPWV of the CAD patients was higher (14.2±2.0) m/s than that of the normal subjects.On Masson's-stained specimen slides,disorganization of smooth muscle and focal accumulations of collagen (44.1 ± 3.9)％ were visible alongthe medial aorta of the CAD patients.Weigert's-stained cross sections of the ascending aortic media in CAD patients frequently exhibited focal breakdown or discontinuous segments of elastic fibers(18.4±3.2)％,cfPWV had a positive correlation with relative contents of collagen in the ascending aorta(r=0.68,P＜0.01)and a negative correlation vith relative contents of elastin in the ascending aorta (r=-0.59,P＜0.01),but no relation with relative contents of smooth muscle(r=0.01,P＞0.05).Conclusions The reduced aortic elasticity in CAD patients can be partly ascribed to decreased elastin,increased collagen,and their disorganization.cfPWV can reflect the quantitative changes of collagen and elastin in the ascending aortic media in CAD patients.

Objective To evaluate the effect of CPB with or without cardioplegia on hemodynamics and myocardial function. Methods Thirty NYHA class III patients undergoing mitral valve replacement were randomly divided into three groups of ten each: group Ⅰ received no blood cardioplegia; group Ⅱ received tepid blood cardioplegia solution and group Ⅲ received cold blood cardioplegia solution. The patients were premedicated with pethidine 50mg and scopolamine 0.3mg. Swan-Ganz catheter was inserted via right interval jugular vein into pulmonary artery and radial artery was cannulated under local anesthesia before anesthesia. Anesthesia was induced with midazolam 0.05-0.01 mg.kg-1, fentanyl 15-20?g. kg-1 and pancuronium 0.12mg.kg-1 and maintained with fentanyl, midazolam and pancuromium. Patients in group Ⅰ received no cardioplegic solution. Ascending aorta was not cross-clamped. Body temperature was reduced to 32℃-33 ℃ (naso-pharyngeal T) . The empty heart was beating at 40-60 bmp. In group D and Ⅲ cardioplegic solution (modified St. Thomas solution) was added to blood from oxygenator (in the proportion of 1:4).In group Ⅱ body temperature was reduced to 32℃-33℃.Tepid (32℃ ) hyperkalemia blood cardioplegic solution was infused at 200-250ml.min-1 after ascending aorta was cross-clamped. After cardioplegic arrest hypokalemic blood cardioplegia solution was infused. In group Ⅲ body temperature was reduced to 28℃-29℃. Cold (8℃) hyperkalemic blood cardioplegic solution was infused at 200-250ml. min-1, after ascending aorta was cross-clamped. After cardioplegia arrest cold hypokalemic blood cardioplegia solution was infused every 20 min. Hemodynamic parameters (MAP, MPAP, CO, CI, SVRI, PVRI, LVSWI and RVSWI) were recorded before anesthesia (T0), before CPB (T1), 10, 30, 60 min after termination of CPB (T2-T4 ) and at the end of surgery (T5 ) . Results Demographic data including age, gender, body weight and body surface area were comparable between the three groups. CI in group 1 and Ⅱ was significantly higher at T2 -T5 than that in group Ⅲ . SVRI after CPB in group Ⅰ was significantly lower than that in group Ⅲ . Conclusion The myocardial function after CPB without cardioplegia is better than that after CPB with cold cardioplegia, but is not significantly different from that after CPB with tepid blood cardioplegia.
