Objective To determine the plasma urolensin Ⅱ(UII) levels in various types of coronary heart disease and to clarify how the plasma UII levels correlate with the clinical presentation, extent and severity of coronary artery atherosclerosis (CAD). Methods: One hundred and three aged patients undergoing elective diagnostic coronary angiography for proven or clinical suspected coronary heart disease were enrolled in this study. The extent and severity of coronary artery disease were evaluated by vessel score and Gensini score, respectively. Plasma UII levels were measured by radioimmunoassay. Results: The plasma UII levels in the patients with modest to severe coronary stenosis (3.03±0.34 pg/ml, 1.83±0.67 pg/ml) were significantly lower than that in subjects with normal coronary artery (4.80±1.11 pg/ml, Pe plasma UII levels in patients with coronary heart disease were also significantly lower than that in patients with insignificant coronary stenosis (P ed to patients with stable angina pectoris, plasma UII levels in patients with acute coronary syndrome were significantly decreased (1.89±0.51 pg/ml vs 2.42±0.77 pg/ml, P evels were found to be negatively correlated with the severity of coronary artery stenosis (r = -0.488, Pell as the vessel score (r = -0.408, Pe patients with CAD. Conclusion: Significant inverse correlations exist between the plasma UII levels, and the extent and severity of coronary artery stenosis. These findings suggest that plasma UII contribute to the development and progression of coronary artery stenosis, and may be a novel marker to predict clinical types, as well as the extent and severity of coronary artery disease in the patients.

Objective The aim of the study is to investigate the effects of psychosocial factors on the treatment of elderly patients with hypertension. Methods Atotalof 260 elderly Chinese patients with hypertension were treated with benazepril alone or benazepril combined with amlodipine for 8 weeks. The target blood pressure (BP) (both eved in 180 patients, who were then assigned to the well-controlled BP group;the rest were placed in the modestly controlled BP group. The psychosocial factors present in both groups were assessed by the Hamilton depression scale, Hamilton anxiety scale, life event scale and social support evaluation list before and after anti-hypertensive treatment. Results There were no significant differences in gender, mean age, hist ory of hypertension, education and smoking habit, or in SBP and DBP between the groups before treatment. Significant differences were also not found in all psychosocial factors before and after treatment in the patients. However, significant differences were found between the groups with respect to post-treatment SBP and marital status. The patients with modestly controlled BP had significantly higher scores, as well as incidents, on the depressive, anxiety, and stressful life event scales than those with well-controlled BP. The patients with well-controlled BP had significantly higher scores in tangible support, subjective support, and social support compared to the patients with modestly controlled BP. Logistic regression analysis showed the independent contribution of psychosocial factors in reaching the goal of lowering BP at treatment endpoint in these hypertensive patients. Conclusions The results suggest that psychosocial factors stand as a main barrier to achieving the BP-lowering target in the management of elderly Chinese patients with hypertension.(J Geriatr Cardiol 2007;4:202-207.)

In order to analyze the adaptation potential of tomato shoots to a sudden increase in Cd concentration, tomato plants （Solanum lycopersicum L. var. Ailsa Craig） were exposed under controlled environmental conditions to a high dose of this heavy metal （250 μm CdCl2） in nutrient solution for 7 and 14d. Both root and shoot growth was completely inhibited but all plants remained alive until the end of the treatment. Cell viability remained unaffected but the activity of the mitochondrial alternative pathway was stimulated by Cd stress at the expense of the cytochrome pathway. Cadmium concentration was higher in roots than in shoots and a decrease in the rate of net Cd translocation was noticed during the second week of stress. Cadmium decreased both leaf conductance （gl） and chlorophyll concentration. However, the effect on net CO2 assimilation remained limited and soluble sugars accumulated in leaves. Photochemical efficiency of PSII （FvlFm） was not affected despite a decrease in the number of reaction centers and an inhibition of electron transfer to acceptors of PSII. It is concluded that tomato shoot may sustain short term exposure to high doses of cadmium despite growth inhibition. This property implies several physiological strategies linked to both avoidance and tolerance mechanisms.

Natural or human-influenced disturbances are important to the health and diversity of forests, which in turn, are important to the water quantity and quality exported from a catchment. However, human-induced disturbances （prescribed fire and harvesting） have been decreasing, and natural disturbances （fires and insects） have been increasing in frequency and severity. One such natural disturbance is the mountain pine beetle （MPB）, （Denclroctonus ponderosae） an endemic species. A recent epidemic resulted in the mortality of millions of hectares of lodgepole pine （Pinus contorta） forests in Colorado, USA. Beetle-induced tree mortality brings about changes to the hydrologic cycle, including decreased transpiration and interception with the loss of canopy cover. This study examined the effect of the mountain pine beetle kill on source water contributions to streamflow in snowmelt- dominated headwater catchments using stable isotopes （2H and ~80） as tracers. Study catchments with varying level of beetle-killed forest area （6% to 97%） were sampled for groundwater, surface water, and precipitation. Streams were sampled to assess whether beetle-killed forests have altered source water contributions to streamflow. Ground- water contributions increased with increasing beetle-killed forest area （p = 0.008）. Both rain and snow contributions were negatively correlated with beetle-killed forest area （p = 0.035 and p = 0.011, respectively）. As the beetle-killed forest area increases, so does fractional groundwater contribution to streamflow.
