89Sr and 153Sm-EDTMP can relief bone pain and improve patient's life quality. 153Sm-EDTMP may repress bone metastases stronger than 89Sr, and can decrease patient's serum VCA-IgA and EA-IgA level,but the blood toxity is also more serious than 89Sr.

89Sr和153Sm－EDTMP对NPC骨转移病人的疼痛缓解和生活质量的提高有肯定疗效。153Sm－EDTMP对NPC骨转移灶的抑制作用明显强于89Sr，可以部分降低VCA－IgA和EA－IgA水平。153Sm－EDTMP的骨髓毒性较89Sr严重。

Objective To observe the efficacy of aiben on treating the pain of metastatic bone cancer and metastatic focus.

The expression of NF-κB protein is related to progression of the advanced gastric carcinoma. The re-expression of E-cadherin and β-catenin in cancer cells of metastatic lymph nodes from advanced gastric carcinoma existed, and which was closely correlated with tumor grade, may play an important role in the re-growth of cancer cells in metastatic foci.

NF-κB的表达与进展期胃癌的发展过程密切相关，E-cad及β-catenin在转移淋巴结中的再表达是进展胃癌发生的重要事件，二者协同发挥作用，并对癌细胞在转移灶中的聚集生长起重要作用，联合评价其功能具有更重要的临床意义。

The re-expression of α-and β-catenin in cancerous cells of metastatic lymph nodes from advanced gastric carcinoma is existent. and which correlates with tumor grade may play an important role in the re-growth of cancer cells in metastatic foci.

及β-catenin在转移淋巴结中的再表达是进展期胃癌发生的重要事件，二者协同发挥作用，并对癌细胞在转移灶中的聚集生长起重要作用，联合评价其功能具有更重要临床意义。

The expression of PCDNA〓-EGFP plasmid was monitered withfluorescence microscope,and the human thyroid undifferentiated carconoma in situmodel and haematogenous metastasis model were established in nude mice withPCDNA〓-EGFP positive cells.These model were used in discussing tumourmetastasis mechanism and early diagnosis of secondery tumour.

荧光显微镜观察〓-EGFP质粒表达情况，并用转染了PCDNA〓-EGFP质粒的细胞建立人甲状腺裸鼠原位及血源移植模型，探讨其转移机制及转移灶的早期发现。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
