Nitrophenol is a commonly occurring industrial pollutant, which has been found to affect our environment, causing ecological imbalance. Biodegradation is a useful strategy to detoxify wastewater and polluted environment, which is the best choice of the nitrophenol contaminated soil remediation.

硝基酚为工业上常见的污染物之一，对环境造成重大之冲击，生物降解因具高之经济效益，且可用於去除受污染的环境，故可做为土壤硝基酚污染整治的最佳选择之一。

Overexpress of Cks1 and Skp2 in LSCC strongly correlated with the TNM stage, lymph

Cks1和Skp2通过对p27的泛素化降解，参与LSCC的发生发展过程；Cks1、Skp2和p27可作为LSCC患者判断预后的有效参考指标。

The results indicated that the typical apoptosis was induced by PRRSV in lungs and uteri. The ultrastructural changes showed different characterizations at different stages of the infection. During the early stage from 8th h to day 3 postinfection,the apoptosis cells shrank,the cytoplasm concentrated,the chromatin condensed,the kernel disaggregated and the endoplasmic reticulum dilated. During the middle stage from day 5 to day 9 postinfection,the apoptosis cells evidently shrank,the cell membranes protu berated,the plastosome manifolded,and apoptosis bodies were found. During the last stage from day 10 upwards postinfection,the apoptosis bodies degenerated and disappeared,and no inflammation occurred. Few apoptosis cells were necrotic.

结果表明，PRRSV可诱导宿主肺和子宫发生典型的细胞凋亡，表现为细胞的超微形态结构随着病毒感染进程出现不同的特征性变化，早期（感染后第8 h至第3 d）凋亡细胞多表现为细胞体积缩小，细胞质密度增强，染色质浓缩，核仁解体，内质网扩张；中期（感染后第5 d至第9 d）凋亡细胞体积显著缩小，细胞膜突起，线粒体增多，有凋亡小体形成；晚期（感染后第10 d以后）凋亡细胞形态多表现为凋亡小体降解和消失，少数凋亡细胞在凋亡晚期表现为坏死细胞。

The SPECT imaging of ~(99)Tc~m-GEBP11 can show the tumor mass clearly and ~(131)I-GEBP11 has anti-tumor effect with weak toxicant and secondary effect, which is the foundation for them to develop nuclide probe or radiotherapeutics drugs targeting to tumor vasculature.3. GEBP11 can inhibit angiogenesis, which comes true probably through its inhibition effects on the proliferation, invasion, migration and adherence of ECs.

1、GEBP11具有活体内胃癌血管靶向结合的能力，它与胃癌血管内皮细胞膜受体特异结合后可被内化。2、~(99)Tc~m-GEBP11 SPECT成像能较好地显示体内肿瘤灶，~(131)I-GEBP11具有明显的抗肿瘤效应及较弱的毒副作用，为开发肿瘤血管成像核素探针及受体放射治疗新药奠定了基础。3、GEBP11具有抑制胃癌血管生成的作用，这可能通过抑制ECs增殖、基质降解及迁移、粘附能力实现。

Whangkeumbae and Huangguan Pear were used in the determination of SA immersion, 1mmol/L significantly delayed the degration of starch, titrable acid, vitamin C and cellulose and maitained higher contents of protein and free amino acid under both room and low temperature, and lmmol/L maintained higher content of soluble sugar during storage anaphase under room temperature.

在常温和冷藏条件下，1mmol/L水杨酸处理果实，能够显著抑制黄金梨和黄冠梨果实中淀粉、可滴定酸、维生素C的降解，保持其较高的可溶性蛋白和氨基酸的含量，并保持了常温贮藏后期较高的可溶性糖含量。

The method includes the following steps: getting specific amount of knitted or unknitted natural fiber and dipping the natural fiber in the aqueous solution of silane coupling agent for 1-100min, taking out and drying the natural fiber, thus producing natural fiber with modified surface; then pressing the polylactic acid into sheet in a plate vulcanization machine; disposing 2-10 polylactic acid sheets into a die and arranging one modified natural fiber sheet between every two polylactic acid sheets; pressing and molding the sheets; in this way totally biologically degradable polylactic acid composite material can be made.

该方法为：先取一定量的经过编织或未编织天然纤维，将其浸渍在偶联剂水溶液中1～100分钟后取出，经干燥后得到表面改性的天然纤维。然后，将聚乳酸在平板硫化机中压制成薄板；将2～10片聚乳酸薄板放在模具中，且每2片之间放置1片改性的天然纤维，然后模压成型，得到可完全生物降解聚乳酸复合材料。

Case-study from Silurian sandstones in the Central Tarim show that quartz has kept overgrowing secondarily when oil saturation was decreased by meteoric water flushing subsequently to hydrocarbon emplacement.

同时，油气侵位是否有利于次生孔隙的发育，也值得研究。塔中地区志留系实例研究显示，烃类侵位后可因淡水注入而被氧化和生物降解，所产生的酸性环境有利于矿物的溶解。
