A liquid discharge pipeline is connected to the plasma input pipe between the plasma input pump and the adsorption filtration pipeline through a liquid discharge three-way pipe, and a replacement pipeline is connected to the plasma output pipe close to the blood return pipe through a replacement three-way pipe. According to the utility model, the DPMAS mode and the plasma exchange mode can be conveniently switched, the operation steps can be simplified, and the infection risk of a patient can be reduced.

An optimizing device for freely switching RBC removal and plasma exchange are provided, which is used to solve the problems in the prior art that the treatment effect is poor, the consumption of consumables is excessive, and the application range is narrow. According to the device, an additional hanging hook is added, a plasma exchange output pipeline is modified to be separated from the plasma collection pump and to be installed to the additional hanging hook. Then, the RBC recirculation tube is clamped through a freely movable cassette, so that the flow rate control of a plasma collection pump is released. Thereafter, HCT data is adjusted, and liquid is compensated, so that the RBC removal or replacement, lymphoplasma exchange and plasma exchange can be freely switched, which can meet the clinical treatment needs, optimize the process and reduce the cost. Therefore, the application range of a pipeline is greatly increased.

The invention pertains to treating a cognitive impairment, for example, an aging-associated cognitive impairment. In certain aspects, a sample obtained from a subject is assayed for the ratio between the levels of any two proteins selected from: DLL1, SMOC1, CD59, TSTD1, STAT3, POLD4, PARP11, LEFTY2, UNC5B, C5, C5.C6, ASH2L, INHBB, RSP3, VAV3, SIRT3 and SERPINB8. A subject may be having or suspected of having a cognitive impairment. The cognitive impairment can be caused by a neurodegenerative disease, such as Alzheimer's disease. A subject may be identified as likely or not likely to respond positively to the plasma exchange therapy based on the ratio between the levels of measured proteins. In certain aspects, methods for treating a cognitive impairment in the subject comprise administering a plasma exchange therapy comprising a full and / or low volume plasma exchange. Also provided are kits suitable for performing such methods.
