We prove the non-existence of Hopf real hypersurfaces in complex two-plane Grassmannians whose Jacobi operators or the Jacobi corresponding to the directions in the distribution are of Codazzi type if they satisfy a further condition. We obtain that that they must be either of type (A) or of type (B) (see [2]), but no one of these satisfies our condition. As a consequence, we obtain the non-existence of Hopf real hypersurfaces in such ambient spaces whose Jacobi operators corresponding to -directions are parallel with the same further condition.

＜正＞PURPOSE: High-dose preoperative radiotherapy has shown promising results in the treatment of low rectal cancer（LRC）. Laparoscopic procedure provides an enhanced view of the pelvic cavity that is not available by conventional method. We developed a sphincter-saving procedure combining the advantages of preoperative radiotherapy and laparoscopy for preserving anatomic and physiologic anal function. Our purpose is to show detailed information regarding procedure and early results. METHODS: From February 1996 to August 1997, eleven patients with LRC underwent the operation. Mean age was 56.1 years. Tumor located 4～8 cm from anal verge. All patients were treated with high-dose preoperative irradiation （4500～5040 cGy） over a period of 5 weeks. All were given our procedure four and a half to eight weeks after completion of radiation. Left colon and rectum were mobilized by laparoscopic oncologic dissection down to puborectalis muscle, after which specimen retrieval and coloanal anastomosis were performed transanally. We concluded with temporary transverse colostomy for fecal diversion. Careful follow-up of 4 to 21 months has so far been given. RESULTS: Every case was successful without any significant complication, and all revealed advantages of laparoscopy. There was one case of complete remission following radiation, and "five were stage Ⅰ, four stage Ⅱ, and one stage Ⅲ. Margin from the tumor was 1～5 cm distally, 19～32 cm proximally, 0.3～3.5 cm laterally. We had one local recurrence 11 months after operating. CONCLUSION: We have termed our procedure ’Laparoscopic Abdominal Transanal （LATA） Proctosigmoidectomy with coloanal anastomosis （LATA resection）’, and propose it as a functional and curative alternative for LRC while continuing to evaluate its efficacy.

The Kulun region is located in the eastern Bainaimiao arc belt on the southeastern margin of the Central Asian Orogenic Belt(CAOB), adjacent to the North China Craton(NCC) to the south. This region records the closure of the PaleoAsian Ocean during the Paleozoic to early Mesozoic and is key to study the tectonic evolution of the northern margin of the *** conducted zircon U-Pb geochronology and Hf isotope analysis of volcanic-sedimentary and intrusive rocks in the Kulun region. The volcanic-sedimentary rocks were previously assigned an early Carboniferous age, but include volcanic rocks with ages of 267–266 Ma and sedimentary rocks with youngest detrital zircon age peaks of 265–244 Ma, which were intruded by a granite with an age of 242 Ma. This indicates that these rocks are actually middle Permian to Middle Triassic in age(267–242Ma) and correspond to the Qingfengshan and Liujiagou formations. Moreover, two volcanic rock samples have high εHf(t) values(+1.6 to +16.1) and relatively young two-stage Hf model ages(1095–327 Ma), indicating their sources associated with the CAOB. The age spectra and Hf isotopic characteristics of detrital zircons from the sedimentary rocks suggest that, during the middle Permian to Middle Triassic, the sedimentary provenance in the Kulun region was mainly the CAOB. However, by the Early Jurassic, the provenance changed to the NCC(i.e., the Inner Mongolia Paleo-uplift, IMPU). This result, combined with the development of a series of conglomerates on the northern margin of the NCC in the Late Triassic(i.e., Xingshikou, Xiaoyingzi,and Xiaohekou formations), indicates the Kulun region experienced an abrupt change in paleogeography during the Late Triassic, with the IMPU undergoing significant uplift and thus becoming the main sediment source in the Kulun region. Based on the Late Triassic alkaline igneous belt(235–215 Ma) in the IMPU, we speculate that this uplift was caused by detachment of the southward-subducting Paleo-Asian oceanic

MicroRNAs （miRNAs） are small non-coding RNAs that negatively regulate gene expression at the post-transcriptional level. They are involved in important biological processes including development, homeostasis, and ageing. Recently, extracellular miRNAs have been discovered in the bloodstream and bodily fluids. These miRNAs are shown to be secreted and circulating in microvesicles （MVs）, or in complex with other factors such as RNA-binding proteins and high-density lipoprotein （HDL） particles. These cell-free, circulating miRNAs can be taken into and function as negative regulators of target genes in recipient cells. Here we review the biogenesis and uptake of circulating miRNAs as well as their profiles in ageing and ageing-related diseases. We discuss the emerging role of circulating miRNAs as biomarkers and therapeutic targets.
