| 1 | A new route for length measurement by phase-shifting interferometry显示文摘By the mathematic models of flexible hinge,the accurate relationship between the phase-shifting and pressure acting on the hinge is deduced and verified by experimental results.Through the optimization of the geometric parameter of flexible hinge,a phase-shifting generator is developed to determine the length of an object precisely by interferometry.The experiments show that the triple phase-shifting produced using this generator is up to 1 m.With this generator,an example for the application in length measurement is introduced.The result shows the length uncertainty is 0.5 nm when the temperature uncertainty is limited in 2 mK.This paper provides a novel technique to measure the dimension of an object,especially to the diameter of a silicon sphere for Avogadro constant project. | LUO ZhiYong LI ZhangHong | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，4： | 3 |
| 2 | Photochemical and electrochemical strategies in C-F bond activation and functionalization显示文摘The activation and functionalization of C-F bonds under mild conditions can serve as an important tool for organic syntheses including the modification of pharmaceuticals and agrochemicals and the synthesis of value-added chemicals.However,owing to their high energy and low activity,C-F bonds are difficult to activate. | Zhanghong Wang Yu Sun Liu-Yu Shen Wen-Chao Yang Fei Meng Pinhua Li | 2022 | Organic Chemistry Frontiers2022，9，3： | 1 |

| 4 | Intrauterine hyperglycemia impairs endometrial receptivity via up-regulating SGK1 in diabetes显示文摘Diabetes is a complex metabolic disorder which can adversely affect reproductive function. SGK1 is found to be up-regulated in multiple tissues of diabetic patients. However, the effects of diabetes on endometrial SGK1 expression and endometrial receptivity remain unknown. In this study, we established a streptozotocin-induced diabetic mouse model and observed reduced implantation sites, retarded development of pinopodes, increased SGK1, and aberrant expression of LIF and MUC1 in the endometrial epithelium. We injected the uterine lumen of normal mice with high-glucose solution and cultured endometrial cells in high-glucose medium to mimic intrauterine hyperglycemia. Both studies provided compelling evidence that hyperglycemia could lead to diminished embryo implantation and dysregulated SGK1, LIF and MUC1. Additionally, through over-expression of SGK1 in vivo and in vitro, we found that enhanced SGK1 also decreased LIF expression, increased MUC1 expression, and attenuated embryo implantation rate. We further identified that hyperglycemia-activated SMAD2/3 might be responsible for the enhancement of SGK1 and verified directly the interaction between SMAD3 and corresponding SMAD binding elements within SGK1 promoter. Taken together, our study confirmed the association between diabetes-related hyperglycemia and endometrial receptivity defects. Hyperglycemia-induced SGK1 has a tremendous role in this pathological process, rendering it as an attractive therapeutic target for diabetes-related reproductive disorders. | Haiyan Xu Jingyi Li Luyang Jin Dan Zhang Bin Chen Xinmei Liu Xianhua Lin Yiting Huang Zhanghong Ke Juan Liu Lin Gao Jianzhong Sheng Hefeng Huang | 2022 | Science China(Life Sciences)2022，65，8： | 1 |
