It's has been reported that lactoquinomycin and frenolicin B, analogues of kalamycin, can inhibit AKT for the pyran naphthoquinone skeleton they have. We found that although kalamycin has pyran naphthoquinone skeleton, but did not suppress AKT and its downstream signal system, then we make a sytematic analysis on the in vitro anti-tumor effect and mechanism of kalamycin.

有报道其类似物lactoquinomycin和frenolicin B是肿瘤靶点AKT抑制剂，并由此推断吡喃萘醌骨架在AKT抑制过程中发挥主要作用，我们发现虽然卡拉霉素含有吡喃萘醌骨架，但是并不抑制AKT及其下游信号系统；继而对卡拉霉素的体外抗肿瘤作用及其机理进行了系统的分析。

The town and village regime is still a regime under the control of landlord or country gentlement social class.

20世纪40年代的新县制运动是国民党在"地方自治"的旗号下推行的一次大规模的基层政权建设运动，新县制下广东基层政权建设的结果是在县以下乡村社会设立了乡、保两级行政机构；但由于战时广东人才缺乏、经费紧张，规划设计的民意机关只在形式上的建立起来，乡、保民意机关对乡、保行政机构没有能够发挥应有的指挥、监督作用，县政府成为体制内乡、保各级政权唯一的领导者与监督者，"地方自治"未能实现，乡、保基层政权依然是乡村乡绅地主阶级的政权。

The synthesis of the pentacyclic skeleton of Et-743 and the construction of the five chiral centers thereof.1. The core pentacyclic skeleton of phthalascidin was constructed with L-dopa as the starting material via thirteen steps. First, two basic synthons, the C-1 functionalized tetrahydroisoquinoline compounds 8 and N-protected Z-dopa derivative 9, were prepared from L-dopa. They were coupled via amide bond to form the dipeptide compounds 10, which were the first key intermediates. Then the primary hydroxyl groups were transformed into the corresponding amino aldehydes 11 via Swern oxidation. Followed by the intramolecular Pictet-Spengler cyclization, the pentacyclic compounds 12 were synthesized.

五环骨架的构建及五个正确手性中心的确立：1.1我们以L-多巴为起始原料，经过多步官能团保护和转化合成了基本结构单元8然后和苯丙氨酸衍生物9，通过缩合反应生成酰胺中间体10，经Swern氧化得到醛化合物11，然后再次利用分子内改良的Pictet-Spengler反应一步构建c，d两环，得到五环骨架化合物12，最后，实现了21-位羰基向氰基的转化，得到了C-1位官能化的化合物14，化合物14不但具有和Et-743一致的五环骨架，而且分子中五个手性中心立体构型也与其完全相同：其中，3，位和13，位的手性中心由原料L-多巴带入，而1，位，11，位和21，位手性中心则通过不对称诱导而确立。

In view of the above factors, to a certain extent, affected the greenhouses of the application and promotion, plus the current bamboo, wood steel prices rising, the vast rural areas in urgent need of a low-cost, corrosion-resistant, resistant to moisture, anti-aging a new framework to shed Instead of the traditional bamboo, wood, steel materials, in the light of this, I units commissioned by the relevant departments, research institutions and the parties concerned under the guidance of experts, completed a "no-pillar greenhouses skeleton of" key project, supported by aircraft I developed a special formula units, the production of greenhouse skeleton without pillars of quality and cheap, quality higher than that of a steel frame, lower than the cost of bamboo, wood, the technical supervision departments test, the main performance indicators are as follows: the simulation of the actual scope: 5.8 - 6.8KN bending strength ≥ 3.3 KN compressive strength ≥ 20 KN water absorption ≤ 13

鉴于上述因素，在一定程度上影响了塑料大棚的应用与推广，又加之目前竹、木钢材价格不断上涨，现广大农村急需一种价格低廉、抗腐蚀、耐潮湿、抗老化的新型大棚骨架来代替传统的竹、木、钢材料，鉴于此，我单位受有关部门委托，在各方科研机构及有关专家的指导下，完成了《无支柱塑料大棚骨架机》的攻关项目，该机配以我单位研制的特殊配方、工艺生产的无支柱大棚骨架质优价廉，质量高于钢架，成本低于竹、木，经技术监督部门测试，主要性能指标如下：模拟实际受力范围：5.8-6.8KN 抗折强度≥3.3KN 抗压强度≥20KN 吸水率≤13

With DGD method, the electron microscopy observation has provided new information on the process of chromatin migration. That is: Firstly, the nucleus moved toward cell wall and a picture characteristic of synizesis stage of meiosis appeared; Secdonly, the transmigration of chromatin occured through CC, and a more extensive region constituted of nuclear skeleton left behind chromatin, which was named as"clear spaces" under light microscopy; Thirdly, at the late stage of synizesis, most of chromatin had gone into adjacent cells through CC and fused into a whole, and the nuclear skeleton left in the former cell gradually mixed with cytoskeleton in cytoplasm.

DGD—包埋去包埋电镜观察表明：百合花粉母细胞中有类似核纤层的结构存在；在染色质穿壁运动过程中，首先是细胞核向细胞壁靠拢，并可留下瞬间的运行轨迹——细胞核后方出现只有细胞骨架而少有细胞器的区域；其后是染色质开始穿壁，在穿壁染色质后方细胞核内出现无染色质仅有密集的核骨架的区域，到了染色质穿壁后期，大部分核物质都已穿至相邻细胞，并彼此融合，而残余在原穿出细胞中的核骨架己逐渐与原细胞的胞质骨架融为一体。

Traditional withdrawing cannot how under this kind of protection with the digestion method the skeleton cell, must use the new method to be able to cause in the skeleton cell DNA to leave from the structure middle reaches, but drifts away at the same time, fears the DNA frail double strand not to be able to undergo fiercely shakes with the intense chemical action, therefore this request must relatively temperately use one kind to withdraw the method.
