Hemangiopericytoma （HPC） is a potential malignant tumor originating from Zimmermann＇s pericytes around capillaries and postcapillary venules, which is most common in soft tissues. Being rarely encountered, intracranial HPC accounts for 2%-4% in meningeal tumors or less than 1% in all intracranial tumors. The histogenesis of this tumor has been debated as a specific aggressive variant of meningioma or angioblastic meningioma for a long time.

土壤杂草种子库是农田杂草发生危害的主要根源,种子库的动态变化规律对于杂草的综合管理具有非常重要的意义。目前研究表明,杂草种子库的密度和组成变化很大,与田间杂草群落具有密切的联系。杂草种子库时刻处于输入和输出的动态变化之中。耕作方式影响杂草种子在土壤中的垂直分布,从而间接影响种子库的密度和种类组成;作物轮作使杂草的生存环境趋于多样化,能够限制某些对单一种植系统有着良好适应性的杂草种类的生长,作物轮作对杂草种子库种类组成和丰富度的影响要大于耕作方式;杂草管理措施能够大大降低田间杂草的结实,从而减小杂草种子库的规模。随着人们对除草剂使用和环境安全问题的日益关注,发展基于生态规律的杂草管理措施越来越受到人们重视,结合近几年国内外的研究进展,作者提出了杂草种子库今后的一些新的研究发展方向。

对杉木立木腐朽病的症状类型、病原菌及发病条件进行了调查分析。结果表明,其发病部位主要在杉木根茎部和树干基部,腐朽表现为心材腐朽、边材腐朽和心材边材共腐朽3种类型;引起病害的病原菌为Eu-rophiumsp.和Geotrichumsp.;病菌的侵入途径是伤口。因此,建议在杉木营林和护林过程中减少伤口的形成,以控制病害的发生。

AIM： To study the influence of high-frequency electric surgical knives on healing of abdominal incision. METHODS： Two hundred and forty white rats were divided into 10^0, 10^2, 10^5, and 10^8 groups and rat models of abdominal operation were induced by using electric surgical knives and common lancets respectively. Then they were respectively given hypodermic injections of normal saline and 0.2 mL quantitative mixture of Escherichia coil, Staphylococcus aureus and Pseudornonas aeruginosa at a concentration of 10^2, 10^5 and 10^8. On the basis of the animal experiment, 220 patients undergoing abdominal operations （above type Ⅱ） were randomly allocated into one of following three groups： electric knife （EK, 93 cases）, electro-coagulation （EC, 55 cases） and control （72 cases）. High-frequency electric surgical knives were used to dissect abdominal tissues and electro-coagulation for hemostasis in EK group. Common lancets and electro-coagulation were applied in EC group. Common lancets and tieing silk suture were used in the controls. RESULTS： In all the groups except group 10^0, infection rate of incisional wounds made by electric surgical knives were remarkably higher than that with common lancets. Furthermore, there were significant differences in groups 10^2, 10^5, and 10^8 （P 〈 0.05）, but not in group 10^0 （P 〉 0.05） between EK and EC groups. Clinical studies showed a delayed wound healing in 16 cases （17.20%） in EK, 11 cases （16.36%） in EC and 2 cases （2.86%）in the control groups. A significant difference between EK and the control groups （χ^2= 8.57, P 〈 0.01）, and between EC and the control groups （χ^2 = 5.66, P 〈 0.05） was observed, but not between EK and EC （χ^2= 0.017, P 〉 0.05）. CONCLUSION： High-frequency electric knives may remarkably delay abdominal incision healing. Its application should be minimized so as to reduce the possibility of postoperative complications.
