To reasonably utilize the coal direct liquefaction residue(DLR), contrasting research on the co-pyrolysis between different low-rank coals and DLR was investigated using a TGA coupled with an FT-IR spectrophotometer and a fixed-bed reactor. GC–MS, FTIR, and XRD were used to explore the reaction mechanisms of the various co-pyrolysis processes. Based on the TGA results, it was confirmed that the tetrahydrofuran insoluble fraction of DLR helped to catalyze the conversion reaction of lignite. Also, the addition of DLR improved the yield of tar in the fixed-bed, with altering the composition of the tar. Moreover, a kinetic analysis during the co-pyrolysis was conducted using a distributed activation energy model. The co-pyrolysis reactions showed an approximate double-Gaussian distribution.

Chlorambucil is a classic nitrogen mustard drug that has been used in the treatment of cancers. It may induce neutropenia, thrombocytopenia and other side effects because of its short lifetime and off-target effect. In this report, chlorambucil-tetrapeptide （AAAK, A3K） conjugate vesicles were developed to improve the stability and bioactivity of chlorambucil. First of all, chlorambucil-A3K conjugate was synthesized by solid phase synthesis strategy. Sec- ondly, the chlorambucil-A3K conjugate was assembled and characterized by critical aggregation concentration, cir- cular dichroism, dynamic light scattering and transmission electron microscopy. The results indicated that the chlo- rambucil-A3K conjugate can be assembled to form spherical vesicles with an average diameter of 390.5 nm, and high drug loading about 47.1% is reached. Surprisingly, the preliminary biological evaluation of the chlorambu- cil-A3K conjugate vesicles revealed the best in vitro anticancer activity against heLa, hepG-2 and MCF-7 cell lines compared with chlorambucil and chlorambucil-A3K conjugate free drugs. Furthermore, conjugate vesicles showed excellent in vivo antitumoral activity. It can be partly attributed to their vesicular structure which isolates chloram- bucil active moiety from aqueous solution to retard degradation before killing cancer cells. Therefore, chlorambu- cil-peptide （A3K） conjugate vesicles may be an alternative delivery system of chlorambucil.

BACKGROUND： Presently, there have been craniocerebral operation, interventional embolization,stereotactic radiotherapy and other methods in treating cerebral arteriovenous malformation （AVM）.However, the standard of different therapeutic regimens of cerebral AVM at the acute stage of hemorrhage has not been completely identified.OBJECTIVE： To observe the clinical characteristics and therapeutic effects of AVM at the acute stage of hemorrhage in patients, and to analyze corresponding therapeutic strategies.DESIGN： Non-randomized clinical observation.SETTING： Department of Neurosurgery, Foshan First People＇s Hospital, Sun Yat-sen University.PARTICIPANTS： Forty-six patients with cerebral AVM complicated by hemorrhage admitted to Department of Neurosurgery, Foshan First People＇s Hospital between January 1999 and December 2006,were involved in this study. All the patients were confirmed as cerebral AVM complicated by hemorrhage by brain angiography or/and postoperational pathology. The involved patients, 32 males and 14 females,averaged 25 years old, ranging from 6 to 62 years. Informed consents of therapeutic items were obtained from the relatives of all the patients.METHODS： ①On admission, skull CT and brain angiography were conducted in the involved subjects. ②The therapeutic method was confirmed according to the consciousness, hematoma region, hematoma volume,imageological results following comprehensive analysis： DSA examination was permitted to identify the size and position of abnormal vessel mass, and the distribution of feeding artery and draining vein. Craniocerebral operation was carried out as early as possible in patients with severe or progressive conscious disturbance, in which most of hematoma with obvious occupied effect or cerebral hernia was located in lobe of brain. The primary thing was to clean intracerebral hematoma for in time decompression. According to different situations, corresponding therapeutic measures were used for resecting abn

以马铃薯2个开花品种YS205和HZ88以及未开花品种YS304为材料,采用石蜡切片法观察花芽分化的解剖学特征,并用酶联免疫吸附法(ELISA)测定开花与未开花品种不同时期叶内4种内源激素——生长素(IAA)、赤霉素(GA3)、玉米核苷素(ZR)、脱落酸(ABA)含量的动态变化,探讨成花过程中叶片内源激素含量和比值的变化与成花的关系,为马铃薯花期调控、栽培和杂交育种提供理论依据。结果显示:(1)马铃薯花芽内部发育与外部形态之间有相对稳定的时序性对应关系,从花芽分化初期生长锥逐渐向上凸起,到雌雄蕊原基形成,完成整个花芽分化仅用了1周左右的时间,此阶段YS205和HZ88的花芽分化过程无明显差异,而YS304未成花。(2)随着花器官的不断发育,HZ88子房形成2室,每室多个胚珠,而YS205的子房在发育过程中发生了变异,形成完整的3室;YS205和HZ88都先后经历了授粉受精过程,HZ88具有一定的自交结实率,YS205无坐果率。(3)马铃薯3个品种的IAA、GA3、ZR和ABA含量在花芽分化前期均较低,且无明显差异性;随后,3个品种的IAA和GA3含量均呈先升后降的单峰变化曲线,但YS304上升和下降的速度较2个开花品种快,而且YS205和HZ88的ZR和ABA含量则始终高于YS304。(4)开花品种YS205和HZ88的ABA/IAA、ABA/GA3、ZR/IAA、ZR/GA3比值均高于未开花品种YS304,且随生育期变化趋势不同。研究表明,较低水平的IAA、GA3和高水平的ABA、ZR均有利于促进马铃薯花芽分化,反之则抑制花原基形态的建成。
