Janus amphiphilic polymer nanosheets(JAPNs)with anisotropic morphology and distinctive perfor-mance have aroused widespread ***,due to the difficulty in synthesis and poor dispersion stability,JAPNs have been scarcely reported in the field of enhancing oil recovery(EOR).Herein,a kind of organic-based flexible JAPNs was prepared by paraffin emulsion *** lateral sizes of JAPNs were ranging from hundreds of nanometers to several micrometers and the thickness was about 3 *** organic-based nanosheets were equipped with remarkably flexible structures,which could improve their injection *** dispersion and interfacial properties of JAPNs were studied *** modification of crosslinking agent containing multiple amino groups,the JAPNs had excellent hydro-philicity and salt resistance compared with conventional inorganic or composite *** settling time of nanosuspension with NaCl and CaCl_(2) at a low salinity of 1000 mg/L was over 240 *** value could also remain 124 h under the salinity of 10,000 mg/L *** the dual functionalities of Janus amphiphilic nature and nanoparticles'Pickering effect,JAPNs could change rock wettability and form emulsions as"colloidal surfactants",In particular,a new technology called optical microrheology was pioneered to explore the destabilization state of nanosuspensions for the first *** precipitation lagged behind aggregation,especially for stable suspension systems,the onset of the unstable behavior was difficult to be detected by conventional methods,which should be the indicator of reduced effec-tiveness for nanofluid *** addition,the oil displacement experiments demonstrated that the JAPNs could enhance oil recovery by 17.14%under an ultra-low concentration of 0.005%and were more suitable for low permeability *** findings can help for a better understanding of the material preparation of polymer *** also hope that this study could shed more light

Optic neuritis is defined as inflammation of the optic nerve. Pain and vision loss are common symptoms ofoptic neuritis. The most frequent cause of optic neuritis is multiple sclerosis： other reasons include viral and bacterial infections, such as hepatitis B and syphilis. We describe a case of a 60-year-old man with a 3-year history of decreased vision acuity in his right eye and a 1-year history of decreased vision acuity in his left eye with light headedness who was admitted to the Neuro- ophthalmological Department of the General Hospital of Chinese People＇s Liberation Army. He had a 2-year past medical history of hypertension and blood pressure instability. None of his family members suffered from vision loss and he had no systemic diseases, especially diabetes mellitus as well as drug usage or toxic exposure.
