Two specieses, Lycoris radiate and Lycoris aurea, were selected for the studying of artificial propagation in vitro. A few specieses of Lycoris, from the southeast area of China and part of locations in Japan, were chosen to research their karyotype differentiation and to measure their genetic diversity by ISSR analysis. The results could be summarized as follows.1. The vegetative propagation conditions of Lycoris aurea and L. radiate in vitro was studied by two-scaling. Different illuminate condition had an effect on the bulblet formation rate. To the species of L. radiate, the rate was higher in the state of 16h 800-12001x illumination than in the darkness. The medium also affected the new bulblet formating rate. When the culture was MS medium 0.2 mg/L NAA 4 mg/L 6-BA, the bulblet formationg rate of L. aurea was 220%;at the same time, when the medium was MS 0.2 mg/L NAA 2 mg/L 6-BA, the rate of L.

The Farming-pastoral Zone in North China was separated into 8 Eco-regions according to the known Eco-region. The dissertation analyzed the regional differences of land use changes from three aspects on dynamic degree , land use degree and the change direction (1)On land use dynamic degree, the dynamic degree of the cropland was the highest in North warm temperate deciduous broad-leaved forest and the lowest in temperate forest steppe; forest land's was the highest in alpine meadow and the lowest in warm temperate forest steppe; grassland's was the highest in temperate forest steppe-bunchgrass steppe and the lowest in alpine meadow; other land's was the highest in North warm temperate deciduous broad-leaved forest-the Huang-Huai-hai plain and the lowest in warm temperate bunchgrass steppe.
结合已有的自然生态区的划分,将我国北方农牧交错带划分为8 个自然生态区,选取土地利用动态度、土地利用程度以及土地利用变化方向等3 个方面的指标对研究区进行了区域分异规律的研究,结果如下:(1)耕地动态度北暖温带落叶阔叶林生态区——北部山地丘陵区最大,温带森林草原生态区最小;林地的动态度高寒草甸生态区最大,暖温带森林草原丛生禾草草原生态区——东南森林草原区最小;草地动态度温带森林草原——丛生禾草草原生态区最大,高寒草甸生态区最小;其他用地的动态度北暖温带落叶阔叶林生态区——黄淮海平原区最大,暖温带森林草原丛生禾草草原生态区—西北丛生禾草草原区最小。

Results:1 case with complicated pyonephrosis was treated with puncture and canalization;Two-stage operations of mini-PCNL was treated 1 week later.20 cases underwent one-stage PCNL,and were treated with single-access PCNL.The total stone clearance rate in one-stage PCNL was 95.2%;residual stones were seen in 5 case(23.8%),Only 1 case had obviously bleeding in or after operation.The mean time of operation was 2 hours,average hospitalization was 12 days.All were followed for 3-12 minths,1 case had recurrent stones.
结果:21例患者中,并发肾积脓1例,先行经皮肾穿刺造瘘术,1周后行二期mini-PCNL,其余20例均行一期穿刺取石,均为单通道穿刺取石,一期结石清除率95.2%;其中术后5例有残余结石,残余结石发生率为23.8%;术中术后有明显出血1例;手术平均时间2小时;平均住院时间12天;随访3~12个月,1例结石复发。

The result showed that the single correlation between the characters of weight and heart girth, chest width and circumference of cannon bone was significantly different. The correlation between weight and heart girth, chest width, circumference of cannon bone was highly positive correlation. Among seven regression models, the correlation index of six regression models was over 0.7, but that of 60 days was 0.452. The result suggested that selecting body weight was efficient through heart girth, body high, chest width and circumference of cannon bone.

Results as bellows: AtSIRT1 was located in Mitochondrial as hSIRT4 of human, and maybe take part in respiration and electron transformation chain, AtSIRT2 was located in nucleolus as hSIRT6 of human, maybe play important role in extend lifespan;mutation in AtSIRT1 leaded to cotyledon of plant turn to yellow and caused short life span. Mutation in AtSIRT2 could make the color of leaf turn to purple and accumulate a lot of anthocyanin;Sirtinol, a inhibitor of SIRT which did not cause the same model of the mutation of AtSIRT1 and AtSIRT2 indicated that the mechanism of Sirtinol was different from other organism;the structure of AtSIRT1 and AtSIRT2 were similar to other known Sir2, which indicated that they maybe have the same function;AtSIRT2 was overexpressed and its activity was detected.
