[Efficacy of Xihuang capsules as an adjuvant treatment for metastatic colorectal cancer and its impact on immune function].

Objective To investigate the efficacy and safety of Xihuang capsules as an adjuvant treatment for metastatic colorectal cancer and their impact on immune function. Methods A retrospective analysis was conducted on clinical data from 112 patients diagnosed with metastatic colorectal cancer. The patients were categorized into two groups: a control group (n=56) that did not take Xihuang capsules and an observation group (n=56) that did.

Cellulose nanocrystal thermal smart molecular brushes with upper critical aggregation temperature.

Grafting thermo-responsive polymers onto cellulose nanocrystals (CNCs) and achieving critical temperature regulation has drawn significant research interest. The thermal transition behavior of CNCs can be controlled by adjusting the polymer molecular brushes on the CNCs surface. We synthesized poly((2-dimethylamino) ethyl methacrylate) (PDMAEMA) grafted CNCs via surface-initiated reversible addition-fragmentation chain transfer, followed by modifying PDMAEMA brushes into poly-3-dimethyl(methacryloyloxyethyl) ammonium propane sulfonate (PDMAPS) brushes via quaternization.
