The isolates of Phytophthora infestans on tomato in the Guangxi Zhuang Autonomous Region, China, were determined for the sensitivities to metalaxyl, cymoxanil and dimethomorph to give the basic information for integrating disease management. Sensitivities were tested by measuring the radial growth on agar medium amended with fungicide, compared with the floating-leaf-disk method. 239 isolates were collected from eight tomato growing areas during 2000-2006. The testing results indicated that the frequencies of sensitive, intermediate, and resistant isolates to metalaxyl were 42.26, 35.98, and 23.53%, respectively. Variations in sensitivities amongst isolates from different areas or different years were very high for metalaxyl. All isolates from Tianlin and Wuxuan were sensitive to metalaxyl, but the metalaxyl-resistant isolates predominated in Tianyang, with the frequency of 51.35%. The EC50 values of certain isolates from Tianyang were higher than 500 μg·mL^-1 and their resistance levels were over 100 000 folds. Cymoxanil has been used for nearly 10 years in Guangxi, and dimethomorph has been used for 5-6 years. However, there was no decrease in sensitivity of P. infestans populations and the sensitivities of the pathogen were nearly normally distributed. Hence, their mean ECs0 value [cymoxanil （0.1647 ±0.0255） μg·mL^-1, dimethomorph （0.0970 ± 0.0052） μg·mL^-1 could be used as the baseline sensitivities for monitoring the field resistance development. The comparison with the floating-leaf-disk method indicates that both the techniques provided equivalent results. These studies suggested that metalaxyl can be continuously applied in Tianlin, Wuxuan, and Nanning due to the resistant isolates that have not been found, while for those areas with resistant isolate, the use of metalaxyl should be reduced or alternated, and cymoxanil or dimethomorph was recommended for controlling late blight disease of tomato.

作为一种新型隧道防水衬砌材料,聚丙烯纤维混凝土的抗渗研究大多还仅局限于抗渗机理的定性解释上。为进一步揭示其抗渗性能,结合断裂力学原理和细观结构的力学分析,推导出了混凝土内部裂纹处的纤维闭合力及其应力强度因子,提出了纤维对张开型裂纹扩展的阻碍效应解析式,并在此基础上,通过数值计算,对聚丙烯纤维混凝土的抗渗性能给出了合理解释;另一方面,为将其与传统的微膨胀混凝土的抗渗性能进行比较,开展了4组不同类型混凝土的抗渗性能试验,通过比较发现,工程中常用掺量的聚丙烯纤维混凝土的抗渗性能优于微膨胀混凝土,而合理双掺(聚丙烯纤维和微膨胀剂)可使混凝土的抗渗性能达到最佳。

AIM： To investigate the tacrolimus dosage requirements and blood concentrations in adult-to-adult right lobe living donor liver transplantation （AALDLT） recipients with small-for-size （SFS） grafts. METHODS： During January 2007 and October 2008, a total of 54 cases of AALDLT with an observation period of 6 mo were enrolled in this study. The 54 patients were divided into two groups according to graftrecipient body weight ratio （GRBW）： SFS grafts group （Group S, GRBW 〈 0.8%, n = 8） and non-SFS grafts group （Group N, GRBW ≥ 0.8%, n = 46）. Tacrolimus 12-hour blood levels and doses were recorded during weeks 1, 2, 3 and 4 and months 2, 3, 4, 5 and 6 in group S and group N. Meanwhile, acute rejection rates, liver and renal function test results, and the number of potentially interacting medications were determined at each interval in the two groups. A comparison of tacrolimus dosage requirements and blood levels were made weekly in the first month post-surgery, and monthly from months 2 to 6. RESULTS： There were no differences in the demo-graphic characteristics, acute rejection rates, liver and renal function test results, or the number of potentially interacting medications administered between the two groups. The tacrolimus dosage requirements in group S were significantly lower than group N at 2 wk （2.8 ± 0.4 mg/d vs 3.6 ± 0.7 mg/d, P = 0.006）, 3 wk （2.9± 0.7 mg/d vs 3.9±0.8 rag/d, P = 0.008）, 4 wk （2.9 ± 0.8 mg/d vs 3.9 ± 1.0 mg/d, P = 0.023） and 2 mo （2.8 ±0.7 mg/d vs 3.8±1.1 mg/d, P = 0.033）. Tacrolimus 12-h trough concentrations were similar between the two groups at all times except for 2 wk post-transplantation, when the concentrations were significantly greater in group S recipients than in group N recipients （11.3 ± 4.8 ng/mL vs 7.0 ± 3.8 ng/mL, P = 0.026）. CONCLUSION： SFS grafts recipients have significantly decreased tacrolimus dosage requirements compared with non-SFS grafts recipients in AALDLT during the first 2 mo post-surgery.

Background Differential diagnosis of intracranial hemorrhage and calcification is a common problem encountered in clinical imaging diagnosis. The purpose of this study was to investigate the feasibility of T2＊ measurement on gradient echo （GRE） T2＊-weighted imaging （T2＊WI） in differential diagnosis of intracranial hemorrhage and calcification. Methods Thirty-eight hemorrhagic foci in 18 patients and 11 calcification foci in seven patients were included in this study. The diagnosis of hemorrhage and calcification was confirmed in all cases with enhanced T2＊ weighted angiography （ESWAN） magnetic resonance imaging （MRI） and CT respectively. The significance for the difference of T2＊ value between the central and peripheral areas of hemorrhage and calcification lesions was tested with univariate analysis of variance, Results The detection rate of GRE T2＊WI on intracranial hemorrhage was 1.9-fold higher than that of CT, especially for the hemorrhage in the brainstem and cerebellum. However, GRE T2＊WI was far less sensitive to calcification than CT. There was a significant difference in the T2＊ value between the central area of hemorrhage and calcification （P 〈0.001）, though no difference in the T2＊ value was obtained between the peripheral area of hemorrhage and calcification （P 〉0.05）. Conclusions Quantitative measurement of T2＊ value on GRE T2＊WI with a single MRI examination provides a fast, convenient, and effective means in differential diagnosis between intracranial hemorrhage and calcification, which may thus reduce the medical cost and save precious time for clinical management.
