| 1 | Sperm cryopreservation in the human sperm bank:11-year results of the Chinese mainland sperm banking network显示文摘To the Editor:Montegazza in 1866 was the first to suggest banks for frozen human semen.[1]In 1981,China's first human sperm bank was successfully established at the CITIC Xiangya Hospital.During the previous four decades,from 1981 to 2020,there were 27 human sperm banks in Chinese mainland.Human sperm banks provide cryopreservation of spermatozoa services for males needing to preserve fertility for an extended period in the Chinese mainland. | Xiao Liu Qiling Wang Wenbing Zhu Zhou Zhang Wenhao Tang Huiqiang Sheng Jigao Yang Yushan Li Xiaowei Liang Tianqing Meng Zhiqiang Wang Faxi Lin Hao Dong Xiaojin He Xianglong Jiang Shanjun Dai Aiping Zhang Chunying Song Zuowen Liang Feng Zhang Xiaojun Wang Peiyu Liang Guihua Gong Xiaohong Huai Fuping Xinzong Zhang | 2022 | Chinese Medical Journal2022，135，22： | 0 |
| 2 | Switched enantioselectivity by solvent components and temperature in photocyclodimerization of 2-anthracenecarboxylate with 6~A,6~X-diguanidio-γ-cyclodextrins显示文摘A series of 6~A,6~X-diguanidio-γ-cyclodextrins(CDs) were used as chiral hosts for mediating the enantiodifferentiating [4 + 4] photocyclodimerization of 2-anthracenecarboxylic acid(AC). These y-CD derivatives form stable 1:2 ternary complexes with AC in aqueous ammonia solutions and the head-tohead photodimers 3 and 4 were greatly enhanced in the presence of these diguanidio-γ-CDs. The enantioselectivity of chiral photodimers 2 and 3 is a critical function of the temperature and the ammonia contents, showing inverted product chirality by changing these external factors. | Jigao Yi Wenting Liang Xueqin Wei Jiabin Yao Zhiqiang Yan Dan Su Zhihui Zhong Guowei Gao Wanhua Wu Cheng Yang | 2018 | Chinese Chemical Letters2018，29，1： | 0 |
| 3 | Photochemical graft of γ-cyclodextrin's interior leading to in-situ charge-transfer complexes with unusual regioselectivity and its application in 3D photo-printing显示文摘Photoirradiation of anthraquinone(AQ)derivatives withγ-cyclodextrin(γ-CD)in aqueous solution led to aγ-CD derivative with a 9,10-dihydroxylanthracene grafting unprecedentedly at the 5′-position of one glucoside ofγ-CD in high efficiency.Meanwhile,another AQ enters into the remaining space of the 9,10-dihydroxylanthracene-occupiedγ-CD cavity to in-situ form a selfincluded quinhydrone charge transfer(CT)complex.The structure of the supramolecular CT complex was unambiguously demonstrated by 1 D and 2 D NMR(^(1)H NMR,^(13)C NMR,DEPT,^(1)H-^(1)H COSY,HSQC,HMBC,TOCSY,and ROESY)spectroscopies,which revealed a highly stereoselective stacking of the quinhydrone pairs in theγ-CD cavity.The supramolecular CT complex showed an unusually high binding affinity and improved oxidation resistance.Polyacrylamides bearingγ-CD or anthraquinone were respectively synthesized by co-polymerization of acrylamide with the corresponding monomer.Photoirradiation of aqueous mixtures containing these two types of polymers led to gelation,which was applied to 3 D photo-printing of soft materials. | Dongjing Zhang Wenting Liang Jigao Yi Jinlei Chen Yongjun Lv Ting Zhao Chao Xiao Xiangyu Xie Wanhua Wu Cheng Yang | 2022 | Science China Chemistry2022，65，6： | 0 |
