The present invention provides targeting polyplexes comprised of (i) nucleic acids, in particular nucleic acids encoding pharmaceutically active peptides or proteins, and (ii) targeting conjugates comprising LPEI and PEG fragments that are connected by discrete linkages formed through defined, chemoselective reactions. Thus, the LPEI fragment is bonded in a linear end- to-end fashion to a single PEG fragment. The linear conjugates are further conjugated to a targeting fragment to enable selective interaction with a particular cell type. The polyplexes selectively deliver the nucleic acids to the targeted cells resulting in high expression and efficient protein translation as well as secretion of the encoded pharmaceutically active proteins.

The application relates to a retinal cell type-based visual function related parameter acquisition system and belongs to the technical field of medical auxiliary systems. The application aims to accurately acquire a retinal cell type-based visual function related parameter acquisition system of L cone, M cone, S cone, ipRGCs and other different retinal cell type function related physiological parameters. The system of the application comprises a stimulation presentation module, a brightness calibration module, a biological signal acquisition module, a multi-dimensional parameter extraction and cell type specific parameter decoupling module, a parameter analysis and standardized output module, a user interaction module and a data storage module. The application can provide a portable, objective, non-invasive and cell type specific retinal function related parameter acquisition technology, provide comprehensive and reliable technical support for visual function evaluation, is suitable for large-scale parameter acquisition and home monitoring, and solves many limitations of the prior art.

The present invention relates to Shiga toxin effector polypeptides with reduced antigenic and / or immunogenic potential. Immunogenicity can be a limitation for the repeated administration to mammals of proteins and polypeptides derived from Shiga toxins. The Shiga toxin effector polypeptides of the present invention have uses as components of therapeutics, diagnostics, and immunization materials. The cytotoxic proteins of the present invention have uses for selective killing of specific cell types and as therapeutics for the treatment of a variety of diseases, including cancers, immune disorders, and microbial infections. The proteins of the present invention also have uses for detecting specific cell types, collecting diagnostic information, and monitoring the treatment of a variety of diseases, such as, e.g., cancers, immune disorders, and microbial infections.

This invention belongs to the field of pharmaceutical technology and discloses a pharmaceutical composition of a USP7 inhibitor and fenofibrate and its antitumor application. The pharmaceutical composition uses a USP7 inhibitor and fenofibrate as the core active ingredients, with a molar ratio of 0.015625 to 0.625. The USP7 inhibitor is selected from at least one of LX04-104 and LML-17-133. This invention is the first to discover that fenofibrate can significantly enhance the antitumor effect of the USP7 inhibitor, and the combination of the two has a synergistic effect. This synergistic effect is cell type specific, particularly significant for nasopharyngeal carcinoma and pancreatic cancer, and the synergistic effect of fenofibrate is independent of the PPARα pathway. This composition can be prepared as an oral or injectable formulation for the treatment of nasopharyngeal carcinoma and pancreatic cancer, and has good prospects for clinical translation.
