The preparation method has the beneficial effects that the degradable polymer auxiliary material is used as a dispersion matrix, the stability of medicine quality is ensured, the release period is prolonged, the release behavior is improved, no obvious sudden release or delayed release exists in in-vitro release, continuous production can be realized by adopting a solid-solid mixed hot-melt extrusion method, the production efficiency of the implant is remarkably improved, the production cost is reduced, and the preparation method is suitable for industrial production. The industrialization is easy; no solvent participates in the preparation process, no solvent residue exists, and the safety is high; the medicine is dispersed uniformly and released controllably; the preparation is safe and reliable in quality and more beneficial to clinical application.

Methods for treating non-small cell lung cancer (NSCLC) include the administration of a combination of 2,2'-dithio-bis-ethane sulfonate, carboplatin, and pemetrexed. The methods are based on tumor mutational burden (TMB) assessment, with specific treatment regimens tailored to the mutational profile of the tumor. When a low tumor mutational burden is detected in a tumor sample, the combination therapy of 2,2'-dithio-bis-ethane sulfonate, carboplatin, and pemetrexed is administered, offering enhanced therapeutic efficacy.

The present disclosure relates to the treatment of solid cancers, such as breast cancer, colon cancer, and lung cancer (particularly non-small cell lung cancer (NSCLC)), in human subjects using anti-PD-1 antibodies as monotherapy or as combination therapy with, for example, chemotherapy and / or surgery. The treatments provided may be a combination of tiralizumab and chemotherapy prior to surgery, using different doses of tiralizumab in an auxiliary stage after surgery. Administration regimens may include administration of 200 mg of an anti-PD-1 antibody (e.g., tiralizumab) (e.g., every three weeks) followed by tumor resection, followed by administration of 400 mg of the anti-PD-1 antibody (e.g., every six weeks). Furthermore, the chemotherapy may be platinum-based (e.g., carboplatin and / or cis-platinum), and may further include pemetrexed (e.g., for non-squamous cancer) or paclitaxel (e.g., for squamous cancer).

The application discloses a kind of pemetrexed liposome and its preparation method and application, it is made of including 2mg / mL~20mg / mL pemetrexed or its pharmaceutically acceptable salt, 2.2mg / mL~12mg / mL cholesterols, 6.81mg / mL~108mg / mL neutral lipid, 12mg / mL~98mg / mL cationic lipid and 0.12mg / mL~2.12mg / mL PEG-lipid.The pemetrexed liposome of the application can significantly improve the enrichment of pemetrexed drug in tumor site, thereby enhancing drug treatment effect, reducing dosing dose, reducing the toxic side effects of drug on normal tissue.And it has good stability, no obvious change in storage process nature, particle size, zeta potential and encapsulation efficiency.

This invention relates to the field of biomedical technology and provides the application of pemetrexed in the preparation of anticoccidial drugs. This invention discloses a novel application of pemetrexed in the preparation of anticoccidial drugs, verifying that the compound has clear anti-parasitic activity in vitro, significantly improves chick survival rate, weight gain, reduces oocyst expulsion, and alleviates cecal lesions in vivo, with an anticoccidial index (ACI) rating of moderate efficacy. Furthermore, it exhibits low cytotoxicity and good safety, providing a new candidate and application direction for anticoccidial drugs.

The application relates to application of a combined use of bruceine D and pemetrexed in the preparation of a drug for treating lung cancer, and belongs to the technical field of biological medicine. The combined use of bruceine D (BD) and pemetrexed (PEM) for treating lung cancer shows a synergistic effect, can more effectively inhibit tumor growth than single drugs, more significantly inhibit lung cancer cell activity and proliferation capacity, reduce lung cancer cell colony formation capacity, and inhibit tumor volume increase and terminal tumor weight increase. In a pemetrexed-resistant lung cancer model, the single drug BD can play a significant role in inhibiting tumors, inhibit pemetrexed-resistant lung cancer cell activity, reduce pemetrexed-resistant lung cancer cell colony formation capacity, and show independent anti-tumor activity; it is shown that BD has a significant therapeutic effect on pemetrexed-resistant lung cancer, and provides a new intervention means for pemetrexed-resistant lung cancer.

The present invention relates to an inhalable tumor-microenvironment-targeted drug delivery system for treating lung cancer. Specifically, the present invention provides a lipid-polymer hybrid nanoparticle comprising: a poly(lactic-co-glycolic acid) (PLGA) polymer core that encapsulates a first therapeutic agent such as paclitaxel (PTX); and a lipid shell functionalized with pemetrexed (PEM) that performs a dual function as both an anticancer agent and a target ligand. The nanoparticles are directly delivered to the lungs through inhalation, simultaneously target folate receptor alpha (FR-α) of lung cancer cells and folate receptor beta (FR-β) of immunosuppressive tumor-associated macrophages (M2-TAMs) through a PEM ligand, and can repolarize M2-TAMs into an immunoactive M1 phenotype, while exhibiting a direct cancer cell killing effect by PTX and PEM.
