| 1 | Impacts of ozone on the biomass and yield of rice in open top chambers显示文摘The impacts of different O 3 concentration on the biomass and yield of rice were studied by using OTC 1 open top chambers. Experimental treatments included the activated charcoal filtered air (CFA), 50 nl/L (CF50), 100 nl/L (CF100) and 200 nl/L (CF200) concentrations of O 3. The O 3 treatments significantly decreased the total biomass per plant. The elevated O 3 exposure resulted in a more decrease in the root growth than in the shoot growth. Assessments of yield characteristics at the final harvest revealed an O 3 induced decrease in the number of grains per plant, resulting from fewer ears per plant, fewer grains per ear and more unfilled grains per ear. The 1000 grain dry weight and the harvest index (HI) were not changed significantly under 50 nl/L or 100 nl/L O 3 exposure, but reduced by 17.0% and 4.8% by 200nl/L O 3 treatment, respectively. Compared to the CFA treatment, CF50, CF100 and CF200 treatments caused a 8.2%, 26.1%, 49.1% decrease of the grain yield per plant, and a 14 2%, 31 7%, 51 7% decrease of the total biomass per plant, respectively. Linear regression showed that the 7h-daily mean O 3 concentration exposure for 3 months (July September) and AOT40 (cumulative exposure accumulation over threshold 40 nl/L) were well correlated with the relative grain yield. A yield loss of 10% was estimated to be at 46 9 nl/L O 3 for 7h daily mean O 3 concentration exposure or at 12930 nl/(L·h) O 3 for AOT40. | Jin, MB Feng, ZW Zhang, FZ | 2001 | Journal of Environmental Sciences2001，13，2： | 16 |
| 2 | Necessity and indications of invasive treatment for Budd-Chiari syndrome显示文摘BACKGROUND:The development of collaterals in Budd-Chiari syndrome has been described and these collaterals play an important role in the presentation of this disease.These collaterals are diagnostic and their use in management strategy has never been evaluated.This study aimed to investigate the indications,feasibility and necessity of invasive treatment for patients with Budd-Chiari syndrome and to determine whether such a strategy is necessary for optimal management.METHODS:Twenty-nine patients who had been treated at our unit were enrolled in this study.Based on physical and biochemical examination,and hemodynamic compensation by collaterals,18 patients underwent radiological intervention (group A),while the other 11 had no invasive treatment (group B).The related hemodynamic parameters were acquired when percutaneous angiography was performed.RESULTS:In group A,all patients underwent successfully inferior vena cava (IVC) balloon angioplasty with or without stenting.Four patients also underwent hepatic vein angioplasty.In these patients,the mean IVC pressure before and after treatment was statistically different (29.3±9.2 vs 15.1±4.6 mmHg,P<0.01).The mean IVC pressure was much lower in group B than in group A (12.9±2.4 vs 29.3±9.2 mmHg,P<0.01),but there was no difference from that of the patients after radiological treatment (12.9±2.4 vs 15.1±4.6 mmHg,P>0.05).Median follow-up was 32.3 months (mean 21.3 months;range 3-61 months).In the course of follow-up,the patients in group A survived with good systemic status except for re-stenosis in one patient who underwent re-canalization of the IVC.In group B,10 patients had good systemic status except one patient who had a meso-caval shunt because of deterioration.CONCLUSIONS:The rationale of 'early diagnosis and early treatment' is not suitable for all patients with Budd-Chiari syndrome.Satisfactory survival can be achieved in some patients without invasive treatment,who are completely compensated by rich collaterals.Nonetheless,a positive treatment procedure should be performed if the patient's situation worsens in the course of regular follow-up. | Department of General Surgery (Fu Y,Sun YL,Ma XX,Xu PQ,Feng LS,Tang Z and Luo CH),Institute of Hepatic Vascular Disease (Sun YL),Department of Radiological Intervention (Guan S and Wang ZW),First Affiliated Hospital,Zhengzhou University School of Medicine,Zhengzhou 450052,China | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，3： | 10 |
