回顾性资料显示,早期低危宫颈癌患者参数浸润发生率较低,这就提出了这些患者是否需要根治性子宫切除术的问题。然而,比较根治性和单纯性子宫切除术结果的大型随机试验数据缺乏。本研究进行了一项多中心、随机、非劣效性试验,比较了低危宫颈癌(病变≤2cm,间质浸润有限)患者的根治性子宫切除术和单纯性子宫切除术,包括淋巴结评估。主要结局是3年盆腔肿瘤复发(盆腔复发)。预先规定的3年盆腔复发组间差异的非劣效性界限为4个百分点。

We developed a new plant transformation vector, pHairyRed, for enabling high throughput, non-destructive selection of Agrobacterium rhizogenes-mediated ＇hairy-root＇ transformation, pHairyRed allows easy in planta visualiza- tion of transgenic tissue with minimal disturbance to the plant. The DsRed2 reporter gene, encoding a red fluorescent protein, was cloned to yield pHairyRed （harbouring a multiple cloning site）, which was used with the highly efficient K599 A. rhizogenes strain to infect soybean （Glycine max L. Merrill） plants. DsRed2 fluorescence was easily detected in planta for the duration of a 5-week study with negligible levels of background autofluorescence. This enabled visual selection of transformed roots and subsequent excission of non-transformed roots, pHairyRed-transformed roots nodu- lated normally when inoculated with Bradyrhizobiumjaponicum. Within the nodule, DsRed2 fluorescence was plant-spe- cific, being absent in the bacteroid-dominated nodule infected zone. To test the reliability of pHairyRed as a high-fidelity binary vector reporter system, the gene encoding the soybean Nod factor receptor, GmNFRloL, was cloned into the vector for use in a complementation study with a non-nodulating nfrloL mutant of soybean. Complementation was achieved and, without exception, DsRed2 fluorescence was detected in all hairy roots that successfully formed nodules （100%, n = 34）. We anticipate broad application of this reporter system for the further analysis of root-related events in soybean and related legumes.

Legumes are highly important food, feed and biofuel crops. With few exceptions, they can enter into an intricate symbiotic relationship with specific soil bacteria called rhizobia. This interaction results in the formation of a new root organ called the nodule in which the rhizobia convert atmospheric nitrogen gas into forms of nitrogen that are useable by the plant. The plant tightly controls the number of nodules it forms, via a complex root-to-shoot-to-root signaling loop called autoregulation of nodulation （AON）. This regulatory process involves peptide hormones, receptor kinases and small metabolites. Using modern genetic and genomic techniques, many of the components required for nodule formation and AON have now been isolated. This review addresses these recent findings, presents detailed models of the nodulation and AON processes, and identifies gaps in our understanding of these process that have yet to be fully explained.

The palynomorph assemblage of lake sediments younger than 51.9 kaBP from Wulagai Gobi in Inner Mongolia was analyzed to reconstruct the vegetation and climate. From 51.9 to 30.6 kaBP, the vegetation was arid to semi-arid grassland with only slight changes. According to the palynomorphs, trees and shrubs were very rare. The large number and diversity of algae indicate the presence of a lake. Quantitative climatic conditions were reconstructed using the Best Analogues Method. The results indicate that the annual mean temperature was higher than that at present. The combination of temperature and annual precipitation suggests a change in the climate from cool dry to warm dry and then cool humid. Our results show that the annual precipitation values were mostly higher than that at present but were lower than 400 mm. It infers that the study area was already within the arid to semi-arid regions but with a stronger influence of the summer monsoon during 51.9 to 30.6 kaBP than at present. With slight differences mainly in time scale, the changing trend of the annual temperature curve is consistent with the other climatic records from Antarctica, Greenland, Hulu Cave （East China）, and the Tibetan Plateau during the last glacial period. From 30.6 kaBP to present, very few palynomorphs were detected in the samples. Hence, no information about the vegetation and climate could be extracted. Combined with other studies during Late Pleistocene, we presume that the reason for the lack of pollen during this period was caused by an abrupt temperature fall after 30.6 kaBP or that the lacustrine conditions were unsuitable for pollen deposition. It was probably incurred by the oxidation on land prior to deposition. But for those samples only with algae, it might be caused by the fact that algae could finish their life history in a very short time in a seasonal lake.

回顾了近年来发表的碳酸盐生油岩方面的文献,尤其是那些详细论述了生油岩岩性和其沉积环境以及生油岩中的有机质等方面的文献。业已证明,适用于其他生油岩的沉积和环境判据,对于碳酸盐同样是有效的。有证据表明,这些生油岩中的粘土矿物的催化作用是微不足道的。所强调的另一特征是“同生源”。文献中列出的证据要求人们重视两种“同生源”模型:1)油气完全是在原地形成并储集起来的;2)油气形成后经过运移并在碳酸盐杂岩体中储集起来。模拟实验得到的结果,无论是已发表的还是未发表的,都将说明上述结论的正确性。

本文回顾了研究碳酸盐源岩的近期文献。这些文献中,特别重要的是提到了该碳酸盐岩的岩石学、沉积环境以及与有机质相关的详细内容,证明了用于其它源岩的沉积和环境标准对于碳酸盐岩来说同样走有充分根据的。给出的资料确认了粘土矿物在碳酸盐岩中的催化作用是最小的。另一个要强调的特征是自生烃。文中回顾了自生烃的两种形式认识上的说法,即:油或气确实走原地的并且在发现的地方生成,或者它能在碳酸盐岩的块体内运移。依据公开的或尚未公开的试验工作所提供的资料提出了文中的一些主要结论。
