Background/aims: Surgical resection is not generally indicated for para-aortic lymph node (PALN) metastasis from colorectal cancer. However, the clinical significance of PALN dissection (PALND) in the current era of modern chemotherapy has not been fully discussed.
Methods: Between November 2006 and February 2013, 14 patients underwent PALND for colorectal cancer and were proven as having pathological PALN metastasis. The median follow-up was 33.2 months.
Results: Primary location was the right-colon in 2 patients, and the left-colon or rectum in 12 patients. The timing of metastasis was metachronous in 5 patients and synchronous in 9 patients. Eleven patients (79%) received perioperative aggressive modern chemotherapy. Neoadjuvant chemotherapy with targeted drugs was introduced in 9 patients (64%) and 6 patients received adjuvant chemotherapy. Recurrence after PALND occurred in 12 patients (86%). The most common site was the lung in 6 patients (43%). The 1- and 3-year disease-free survivals were 39.3 and 7.9%, respectively. The 3-year overall survival were 41.2%.
Conclusion: The recurrence rate after PALND for strictly selected patients was quite high even in the current era of modern chemotherapy. However, some patients achieved long-term survival or could be cured. Therefore, we should re-evaluate the efficacy of PALND in a larger prospective study.

Chronic wounds, especially non-healing wounds, significantly affect patients' quality of life and raise the costs of therapy. Wound healing is a complicated process involving interdependent stages, which may be impaired and delayed by infections with multi-drug resistant pathogens. Current medical strategies for wound healing, especially the treatment of non-healing wounds, exert limited therapeutic effects, thus become a dramatic challenge for modern medicine.

Nucleic acid therapeutics represent a highly promising treatment approach in modern medicine, treating diseases at the genetic level. However, these therapeutics face numerous challenges in practical applications, particularly regarding their stability, effectiveness, cellular uptake efficiency, and limitations in delivering them specifically to target tissues. To overcome these obstacles, researchers have developed various innovative delivery systems, including viral vectors, lipid nanoparticles, polymer nanoparticles, inorganic nanoparticles, protein carriers, exosomes, antibody oligonucleotide conjugates, and DNA nanostructure-based delivery systems.

Natural products, recognized for their potential in disease prevention and treatment, have been integrated with advanced nano-delivery systems to create natural product-based nanomedicines, offering innovative approaches for various diseases. Natural products derived from traditional Chinese medicine have their own targeting effect and remarkable therapeutic effect on many diseases, but there are some shortcomings such as poor physical and chemical properties. The construction of nanomedicines using the active ingredients of natural products has become a key step in the modernization research process, which could be used to make up for the defects of natural products such as low solubility, large dosage, poor bioavailability and poor targeting.

Recent therapeutic strategies have highlighted the potential of β-hydroxybutyrate (BHB) and α-ketoglutarate (α-KG) as effective anticancer agents, particularly for colon cancer. These metabolites can modulate cellular metabolism and induce epigenetic changes, inhibiting tumor growth. Nonetheless, certain cancer cells may utilize ketone bodies, like BHB as nutrient sources under hypoxic conditions, potentially reducing treatment efficacy.
