The Chinese dwarf cherry（Cerasus humilis（bge.） Sok.） is a small shrub with edible fruits. It is native to northern and western China. This species was included as a medicinal plant in the ‘‘Chinese Pharmacopeia’’ and has emerged as an economically important crop for fresh fruit consumption, processing into juice and wine and nutraceutical products as well. To gain a better understanding of flavonoid biosynthesis and help develop value added products and better cultivars with greater health benefits, we analyzed total flavonoid content（TFC）, composition, and radical scavenging activities in fruit extracts of 16 Chinese dwarf cherry genotypes. Fruit peel TFC ranged from 33.5 to72.8 mg/g REáFW（RE： rutin equivalent, FW： fresh weight）while fruit flesh TFC ranged from 4.3 to 16.9 mg/g REá*** HPLC analysis revealed that fruit extracts contained 14 flavonoids with considerable variation in their profiles across genotypes. The most abundant flavonoids in most genotypes were proanthocyanidin b1（PA-b1）, proanthocyanidin b2（PA-b2）, phloretin 20-O-glucoside（PG）, and phloretin 20,40-O-diglucoside（PDG）. Principal component analysis showed that PG, PA-b1, and PA-b2 had large,positive factor loading values in the first principal component for each genotype. Increased scavenging activity of2,2-diphenyl-1-picrylhydrazyl（DPPH） radicals was apparent in genotypes ‘Nongda 4’, ‘Nongda 3’, ‘Nongda 6’,‘Wenfenli’, and ’10-32’, suggesting promising applications in the production of nutraceutical products. In summary, our results will aid in breeding, fruit processing, and developing medicinal uses of the Chinese dwarf cherry.

为了掌握农药喷雾飘移的规律,从而为控制农药飘移到非靶标区域提供理论支持和技术依据,论文测试了由风洞地面向上0.1-0.5 m放置的5根间隔0.1 m以及水平方向距地面0.1 m高从2-6 m放置的5根间隔1 m的聚乙烯收集线所收集的含荧光示踪剂的雾滴,由荧光分析仪测定了收集线上的荧光剂含量,分析了不同位置处的雾滴沉积和飘移。针对Tee Jet公司的XR 11002延长范围扇形喷头、AIXR 11002气吸扇形喷头、TT 11002广角扇形喷头和TTI 11002涡流气吸型喷头在不同位置处的雾滴飘移试验、得到不同类型的喷头在不同风速和药剂时的雾滴飘移结果。结果显示,随着垂直高度和水平距离的增加,雾滴的沉积减少。风速增大时,垂直高度0.1-0.5 m和水平距离2-6 m的雾滴飘移都会更加严重。气吸扇形和涡流气吸型结构的喷头能产生更大尺寸雾滴,减少飘移量。采用SPSS软件建立了包含采样距离、风速、喷头类型和药剂类型在内的多变量非线性雾滴飘移特性模型,经检验,该回归模型的拟合度在0.847以上,此模型有助于降低喷雾飘移的风险,为气象条件的选择、雾滴沉积区域的预测、缓冲隔离区的确定、防飘施药技术的研究和喷施药剂药械的配套选用提供技术指导。

北京大学学报（医学版） 2006年第1期38卷 57-61页

作者： gary LU John ZHANG Katherine PAUPER Department of Pathology and Genetics USLabs/LabCorp Irvine California 91612 USA Department of Hematology/Oncology Quest Diagnostics/Nichols Institute San Juan Capistrano CA 92692 USA

Objective: To study the frequency of interstitial 7q deletions in b-cell lymphoproliferative disorders (b-LPDs). Methods: Cases were collected from the clinical laboratory diagnosis database at USLabs/LabCorp over the past two years (2002 to 2004). Cases that showed deletions in the long arm of chromosome 7 were then reviewed. Interstitial deletions in the long arm of chromosome 7 were further investigated according to the indications for clinical laboratory studies and flow cytometry findings. The final clinical diagnosis for each case was obtained from the referring physician. Results: A total of 19 483 cases were included in this series. Eighty-five cases were observed to have either terminal or interstitial deletion in the long arm of chromosome 7. Of the 85 cases, 46 had interstitial deletions accounting for 54.1% of the 7q deletions combined. b-LPDs were found in 10 of the 46 cases, accounting for 21.7%. The b-LPDs associated with 7q interstitial deletions were diverse, including b-cell chronic lymphocytic leukemia (b-CLL) in five cases. The deleted region in the long arm of chromosome 7 in the 10 cases associated with b-LPDs was solely confined to the 7q22-q32 region. Conclusion: (1) The frequency of 7q interstitial deletions associated with b-LPDs is substantially high; (2) 7q interstitial deletions are not uncommon in b-CLL.

给母亲的一封信

亲爱的妈妈：当一个儿子的母亲已经离去20余年，他如何再说感谢您呢？此刻，在我人生的暮年，我想知道尽管许多次我仅是说：“谢谢您，妈妈”您是否曾明白我多么感激您给予我的一切啊。鉴于当时的情况，那些话语显得多么老套、多么肤浅。
