Promising Pharmacological Interventions for Posterior Capsule Opacification: A Review.

Phacoemulsification combined with intraocular lens implantation is the primary treatment for cataract. Although this treatment strategy benefits patients with cataracts, posterior capsule opacification (PCO) remains a common complication that impairs vision and affects treatment outcomes. The pathogenesis of PCO is associated with the proliferation, migration, and fibrogenesis activity of residual lens epithelial cells, with epithelial-mesenchymal transition (EMT) serving as a key mechanism underlying the condition.

The method enables the use of hydroxyl-unprotected antiviral drugs (acyclovir, ganciclovir, and penciclovir), guanosines, oligonucleotide, and triazole-linked nucleoside dimers as substrates. Nucleoside trimer and tetramer were synthesized by derivatization reactions.

Pan-immune-inflammation value predicts immunotherapy response and reflects local antitumor immune response in rectal cancer.

The pan-immune-inflammation value reflects the systemic inflammatory response, and tumor-infiltrating lymphocytes indicate a local immune response in rectal cancer. However, the association between systemic inflammatory response, as indicated by the pan-immune-inflammation value, and local immune responses in rectal cancer remains unclear. This study analyzed 915 treatment-naïve rectal cancer patients from the Peking Union Medical College Hospital and PLA General Hospital (PLAGH) cohorts who underwent radical surgery to investigate the relationship between the pan-immune-inflammation value and immune responses.
