objective to study the anti-tumor activity and enhancing immune effect of phellinus linteus.methods the anti-tumor activity of phellinus linteus was estimated by the longevity of eac mice,the immune effect of tumorous mice was tested by the experiment of carbon particle expurgation and the il-2 concentration in serum of tumorous mice was determined by elisa.results phellinus linteus can prolong eac mouse's life and can increase the il-2 concentration in serum of tumorous mouse but can't affect the immune effect of tumorous mouse.conclusion chinese hurb phellinus linteus possess some antitumor power for tumor-loaded mice,but further research is needed.

目的 观察桑黄对肿瘤的抑制作用及对机体免疫功能的影响。方法以小鼠艾氏腹水癌的生命延长率评价桑黄的抗肿瘤作用，以炭末廓清实验观察荷瘤小鼠非特异性免疫功能，以elisa法测定荷瘤小鼠血清il-2浓度。结果桑黄对eac荷瘤小鼠的生存时间有延长作用，对荷瘤小鼠血清il-2浓度有提高作用，对荷瘤小鼠非特异性免疫功能无明显影响。结论中药桑黄对荷瘤小鼠具有一定的抗肿瘤能力，作用的强度和作用机制的深度还有待进一步研究。

MJ and geraniol all could inhibit the PLBs growth. With the raising of their concentration , their inhibition inhanced. MJ 100mol L-1 could inhance the accumulation of effective components in PLBs, but geraniol at different concentration inhibited the accumulation of effective components in PLBs.

MJ和牻牛儿醇均会抑制拟原球茎的生长，随着浓度的增加，这种抑制作用增强。100μmol/L~(-1)MJ可以提高拟原球茎中有效成分的积累，而不同浓度的牻牛儿醇都抑制了有效成分的积累。

As a result, to some extent the above models were all restrained by PYJC, indicating PYJC has anti-inflammatory and analgesic effects, the effects of PYJC are similar to PYJG and JJC.

结果，盆炎净胶囊对以上各种实验模型均有不同程度的抑制作用，表明该药具有抗炎与镇痛作用，其作用不弱于盆炎净颗粒与金鸡胶囊。

In a word, mad1 gene or mad1 combining with c-myc gene could inhibit TCCB cell proliferation but not normal fibrocytes in vitro and in vivo, which targeted hTERT, suppressed its transcription and expression, and down-regulated the expression of cyclin D1 and TGF-β1, to further block the cell cycle, change cell morphology and suppress proliferation.

综上所述，mad1基因或mad1联合c-myc基因能在体内外抑制TCCB细胞的增殖，但对正常成纤维细胞无明显影响，二者以hTERT为作用靶点，抑制其转录和表达，并下调cyclin D1和TGF-β1的表达，进而阻止细胞周期、改变细胞形态和抑制癌细胞的增殖。

As a result, has "Yangxue, cooling blood, activating blood and" effect or inhibition of DNA synthesis, improvement of microcirculation function in food, are good for psoriasis, such as fruit drinks like Mume, grapefruit and so on with Qingre , blood-cooling, thirst-quenching Shengjin role, not only rich in vitamins and trace elements, can also lower blood lipids, blood viscosity, grapefruit and Huyou has been proven to inhibit the role of an effective split is effective psoriasis control summer fruit .

The effect factors analysis based on FEM shows that: Raising the strength of concrete and the thickness of cover concrete would delay the cracking of concrete; Stress superposition would appear due to the influence of adjacent rebar, and increasing the rebar space would postpone the time of cover cracking; Stirrup could suppress the cracking of cover concrete, however, the effect is limited and the corrosion-degree-ratio and corrosion expansive force would not increase until the cover concrete cracking happens completely.

结合有限元分析结果，对影响锈胀开裂的各因素进行了分析，结果表明：提高混凝土强度、增加保护层厚度有助于延缓保护层的开裂；相邻钢筋的存在会使钢筋之间的混凝土出现应力叠加现象，箍筋对混凝土保护层内由锈胀产生的应力具有抑制作用，但是在保护层完全开裂之前，箍筋的抑制作用有限。
