Althought this surgery has been reported by a few doctors recently, the safety and effectiveness need to be evaluated in further studies. In our study, the approach of the chorioretinal venous anatomosis in the model eyes with branch retinal vein occlusion, are induced by different surgical anastomosis procedures, in order to invest the effectiveness and safety and make a pilot clinic treatment exploration. Methods and materials The study was divided two ports: animal experiment and clinical study.

这种治疗方法的可行性和疗效评价，在激光诱导脉络膜视网膜静脉吻合术治疗非缺血型CRVO病人中得到证实；而对缺血型CRVO，由于病情严重，晚期新生血管并发症产生的危险性高，或者已有产生，因此最近开展的用玻璃体切除联合手术吻合脉络膜视网膜静脉的外科治疗作为最新的探索性治疗方法，在国外已见少数病例报告，但是尚需要进一步的研究观察来评价其可行性、安全性和疗效。

Photoinduced Electron Transfer [2+2] Cycloaddition Reactions ofBenzannelated Isoquinolin-1-ones with Electron Deficient Alkenes Photoinduced [2+2] cycloaddition reactions of 11H-benzoxazolo[3,2-b]isoquinolin-11-one 8 and 11H-benzothiazolo[3,2-b]isoquinolin-11-one 13 with electron deficient alkenessuch as acrylonitrile, methyl acrylate, dimethyl fumarate and dimethyl maleate afforded a group of polycyclic isoquinoline derivatives bearing cyclobutane moieties ingood to excellent yields and resulted in the Schenck isomerization of the alkenes.

The litterfall P use efficiency was the highest and increased with increasing density, implying that P could be a limiting factor for the growth and regeneration of F. denudate.

缺苞箭竹P的养分利用效率随密度的增大而增高，表明P可能是缺苞箭竹生长更新的限制因子。

The peaks of litterfall production and nutrients return at the three densities were appeared in October (by the end of F. denudate growth season), and another peak at D3 was observed in August.

除高密度(D3)缺苞箭竹在8月有一个凋落与养分归还小峰外，10月生长季末是各密度缺苞箭竹凋落及养分归还高峰期。

在分析I和Q假定意义的基础上定点比较，对照了缺省逻辑与演绎逻辑的差异，并有代表性地分析了支持缺省逻辑推导的知识项如原型等。

Zinc content in the body of pregnant women and fetal growth and development is directly related to maternal zinc deficiency can cause slow fetal growth and congenital malformations, especially the head, spinal and other central nervous system malformation, and zinc deficiency in pregnant women throughout pregnancy when process can be adversely affected, such as maternal infection, delivery of excessive bleeding, fetal distress, stillbirth, miscarriage, pregnancy induced hypertension and other complications, more zinc-containing foods include: sesame, buckwheat, corn, cereals, beans products, laver, peanut kernels, walnut kernel, beef, pork, mutton, fish, Gordonia.

孕妇体内锌的含量与胎儿的生长发育有直接关系，孕妇缺锌可引起胎儿生长发育缓慢和先天畸形，特别是头部、脊椎等中枢神经系统的畸形，并且孕妇缺锌时整个妊娠过程都可带来不良影响，如母体感染、分娩出血过多、胎儿窘迫、死胎、流产、妊娠高血压综合征等并发症，含锌较多的食物有：芝麻、荞麦、玉米、麦片、豆制品、紫菜、花生仁、核桃仁、牛肉、猪肉、羊肉、大头鱼等。

The method of diagnosing plant diseases intellectively by computer vision that were short of a kind of nutrient in soiless agriculture was proposed on the base of the whole current development of computer vision in agriculture home and abroad. It has a vast range of potential application.
