Phosphate was removed from aqueous environment by corundum-hollow-spheres supported caclined hydrotalcite (cHT) thin films. Mg-Al-CO3 hydrotalcite (HT) thin films were deposited on corundumhollow-sphere substrates by hydrothermal homogeneous precipitation at 120℃for 30-240 min and cHT thin films were obtained by annealing of the HT thin films at 500℃for 180 min. Their crystal phase, morphology and microstructure were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM).The results show that homogeneous, well-crystallized and hierarchical flower-like thin films were deposited firmly on the surface of the corundum. The mechanism of nucleation and growth of the HT thin films was fitted well with the anion coordination polyhedron growth unit model. To determine the absorption of phosphate by this adsorbent, different bed depth (10-30 cm) and flow rate (1.0-3.0 m L/min) were examined by column experiments. The highest removal efficiency of phosphate amounted to 98.5%under optimum condition (pH=7.2). The adsorption capacity increased as the bed depth increased and decreased as the flow rate increased.

激光或单色光(LI)对生物系统存在光生物调节作用(PBM)。II与细胞分子的量子力学相互作用决定了PBM的剂量关系。低强度LI(LIL)(～10 mW/cm^2)的PBM主要由状态依赖的视觉外光信号转导所介导。中等强度LI(MIL)(10~2～10~3 mW/cm^2)的PBM主要由活性氧介导。它们都支持PBM的生物信息模型(biologicalinformation model of PBM,BIMP)。细胞的信号转导通路可以分为两类,Gs蛋白介导的通路为通路1,蛋白激酶C和丝裂原活化蛋白激酶等其他信号通路为通路2。目前发现的光信号转导通路几乎都属于通路2,但BIMP预言了通路1的存在。

鼻腔内低强度激光照射疗法(ILILT)是鼻腔内低强度激光照射在内科疾病方面的临床应用。ILILT由血液、经络和植物神经3条通路介导,至少其中一条通路的功能远离其功能内稳态。血液通路得到ILILT改善血管疾病患者的血脂和血液流变学指标的临床研究的直接证实。ILILT的经络介导假定得到针灸和ILILT临床疗效的比较研究的支持。ILILT的康复作用是通过促进长寿因子(烟酰胺腺嘌呤二核苷酸辅酶依赖的去乙酰化酶)水平的提高介导的。
