Looking at the DrugSupervise.Entity.Models.PhysicsName.PhysicNameList collection, see a bunch of stuff like this:

{ "_id" : BinData(3,"s6CfpmQtDkG5Nh3lqDGOQQ=="), "physicName" : "磷酸可待因注射液", "physicInfo" : "磷酸可待因注射液 注射剂 15mg" } { "_id" : BinData(3,"3Aa7ZwXzy0ax2KRCFRhsSg=="), "physicName" : "硫酸吗啡口服溶液", "physicInfo" : "硫酸吗啡口服溶液 口服液 10ml：30mg" } { "_id" : BinData(3,"t9+GHfNq10eqqi2EaqhQKA=="), "physicName" : "枸橼酸舒芬太尼注射液", "physicInfo" : "枸橼酸舒芬太尼注射液 注射剂 2ml:100vg(以舒芬太尼计)" } { "_id" : BinData(3,"bFLxr6tN0kO8vso+BTjB5w=="), "physicName" : "硫酸吗啡片", "physicInfo" : "硫酸吗啡片 片剂 20mg" } { "_id" : BinData(3,"5FGsZIWsPE6L+UQSTEfVag=="), "physicName" : "盐酸吗啡片", "physicInfo" : "盐酸吗啡片 片剂 30mg" }

I have no idea what this is, but it looks like some kind of registry of prescriptions.
