1. The Study Purpose Skiing tourist destination marketing can be treated as a kind of particular marketing of tourist destination. With the advent of tourism transformation from sightseeing tour to vacationing and leisure activities, skiing is becoming a popular kind of vacation. Skiing tourist destinations have also been constructed and developed. But skiing development in our country is still in its infancy. In many respects,

Diffusion-weighted imaging (DWI) as a new technique of magnetic resonance imaging (MRI) is used to detect focal hepatic lesions. This study was designed to evaluate the significance of DWI to differentiate focal hepatic lesions less than 3 cm in diameter by the quantitation of apparent diffusion coefficient (ADC) values. METHODS:DWI using 1.5T MRI scanner unit was performed with a spin-echo single-shot echo planar imaging (EPI) in 56 cases of small focal hepatic lesions, including hepatocellular carcinoma (11), hepatic metastatic tumor (15 ), hepatic cavernous hemangioma (14), and hepatic cyst (16).The ADC values of these lesions were calculated respectively. The ratios of the ADC values of lesion/liver in hepatocellular carcinomas and hepatic metastatic tumors were also estimated. RESULTS:The mean ADC values (mm2.s) were (0.93±0.06) ×10-3 in hepatocellular carcinomas, (1.09±0.18)×10-3 in hepatic metastatic tumors,(1.95±0.38)×10-3 in hepatic cavernous hemangiomas, and (3.18±0.33) ×10-3 in hepatic cysts. The ratios of ADC values of lesion/liver were 0.90±0.06 and 1.15±0.14 in hepatocellular carcinoma and hepatic metastatic tumors respectively, which were significantly different (P<0.05). CONCLUSION:The measurement of ADC values and the ratios of ADC values of lesion/liver are helpful in MR diagnosis and differentiation of focal hepatic lesions.

In a cDNA library generated from rice small nuclear RNAs, 30 box C/D small nucleolar RNAs (snoRNAs) were identified through preliminary screen. Except 7 known snoRNAs such as U14, all snoRNAs were identified in rice for the first time experimentally. Among the 2. novel snoRNAs, 11 snoRNAs appear rice-specific, 6 snoRNAs are unique to plants, the remaining 6 snoRNAs have their counterparts in both Arabidopsis and yeast or mammals according to the conserved antisense sequences that guide 2.-O-ribose methylation of rRNA. 17 of the 2. novel snoRNAs were predicted to guide 2. 2.-O-ribose methylations at the specific sites of rice 5.8S, 18S, 2.S rRNAs, among which 19 methylated sites were determined by primer extension at low dNTP concentrations. The remaining 6 snoRNAs devoid of rRNA antisense elements may represent novel snoRNA species in rice. The results show that constructing a cDNA library from small nuclear RNAs is an effective experimental approach for novel snoRNA identification. The novel snoRNAs are important in elucidating the genomic organization and expression of plant snoRNA genes and the mechanism through which 2.-O-ribose methylations took place in rRNAs.
