It should be classified as one of the “Shu mirrors” in the upper Yangtze River. Bearing the southern cultural tradition, mirrors with divinity and animal designs in three zones feature that the representation of the immortal world on them does not centre on the images of Huangdi, Shennong and Cangji but emphasizes the sacred icons of Shun (Dijun), Ehuang and Ntiying, characteristic of the southern cultural tradition and strong regionalism. The figure of Xiwangmu on them also differ from that in other areas, showing a distinctive relationship of evolution and replacement with early Buddhist images in the Sichuan region.展开更多

It can further be inferred that the owner of the tomb might have been the Chu crown prince's teacher, the documents from there were teaching material for the prince, and the tomb and bamboo slips go back to a time earlier than 303 BC.展开更多

For all its different forms,democracy is expected to promote people’s well-being,instead of being weaponized to justify hegemony,as democracy is also a principle of global governance.

However, currently there are no studies showing the potential value of clinical applications of contrast-enhanced FLAIR （CE FLAIR） sequence in diagnosing intracranial tumors in a larger group of patients. The purpose of this study was to evaluate the diagnostic value of CE FLAIR in comparison with CE TlWI for intracranial tumors and to provide more information for clinical diagnosis and therapy. Methods One hundred and four consecutive cases of intracranial tumors referred for CE brain MRI were analyzed with regard to FLAIR and TlWI pre- and post-administration of Gd-DTPA. The CE FLAIR and CE TlWI were evaluated independently by two radiologists for the number of examinations with one or more enhanced lesions, the number and location of enhanced lesions per examination, signal-to-noise ratio （SNR） and contrast-enhancement ratio （CER） of lesions, as well as the size and extent of the enhanced lesions. Results In 98 of 104 cases, enhanced lesions were seen both on the FLAIR and TlW images. More lesions were seen on CE TlWI （n=120） than those on CE FLAIR sequence （n=llT）, but no differences of statistical significance were found between the two sequences （/＇〉0.05）. Four lesions were revealed only on the CE FLAIR images whereas 7 lesions were only found on CE TlWI. Enhanced lesions located in the cerebral hemisphere or the forth ventricle were revealed much more on CE T1WI than on CE FLAIR images. However, CE FLAIR images may be useful in showing superficial abnormalities and those located in the sulcus or lateral ventricle. The CER and contrast-to-noise ratio （CNR） on CE T1WI was significantly higher （t=7.10, P=0.00; t=9.67, P=0.00, respectively）, but grey matter/white matter contrast was lower （t=-2.46, P=-0.02） than those展开更多
