A 68-year-old male, who had advanced rectal cancer with multiple pulmonary metastases, had undergone resection of rectal cancer operatively and was treated with a combination chemotherapy using 5'-DFUR (5'-deoxy-5-fluorouridine) and MMC (mitomycin C) for multiple pulmonary metastases. Nine months from the start of this therapy, pulmonary metastatic lesions disappeared completely on chest X-ray examination and computed tomography. This case corresponded to complete response (CR) according to the response criteria proposed by Koyama-Saitoh. No significant side effects were observed during this chemotherapy. From the results in this case, the combination chemotherapy was considered to be one of the effective antineoplastic therapies available for pulmonary metastasis from large bowel cancer.

Department of Traditional Chinese Medicine, Shanghai Fourth People's Hospital Affiliated to Tongji University of Medicine, Shanghai, China.
Based on network pharmacology and molecular docking methods, this study explored its active compounds and confirmed its potential mechanism of action against Hand-foot skin reaction induced by tumor-targeted drugs. Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform and UniProt Database were used to obtain the active ingredients and target proteins of Spatholobi Caulis. All hand-foot skin reaction (HFSR)-related targets were obtained with the help of the Human Gene Database, Online Mendelian Inheritance in Humans (OMIM), DisGeNET and DrugBank databases.

Background: Cryoablation induces antitumor immune responses. Spatial transcriptomic landscape technology has been used to determine the micron-level panoramic transcriptomics of tissue slices in situ.
Methods: The effects of cryoablation on the immune microenvironment in non-small cell lung cancer (NSCLC) were explored by comparing the Whole Transcriptome Atlas (WTA) panel of immune cells before and after cryoablation using the spatial transcriptomic landscape.

Colorectal cancer is the third most prevalent malignant tumor worldwide. Despite the advancements in surgical procedures and treatment options, CRC remains a considerable cause of cancer-related mortality. Shikonin is a naphthoquinone compound that exhibits multiple biological activities, including anti-inflammatory and anti-tumor effects as well as wound healing promotion.

Importance: The prevalence of pharmacies owned by integrated insurers and pharmacy benefit managers (PBMs), or insurer-PBMs, is of growing regulatory concern. However, little is known about the role of these pharmacies in Medicare, in which pharmacy network protections may influence market dynamics.
Objective: To evaluate the prevalence of insurer-PBM-owned pharmacies and the extent to which insurer-PBMs steer patients to pharmacies they own in Medicare.
The Gut in Critical Illness.
Curr Gastroenterol Rep

Division of Pulmonary, Critical Care, and Sleep Medicine, Medical College of Wisconsin, 8701 West Watertown Plank Road, 8th Floor: HUB for Collaborative Medicine, Milwaukee, WI, 53226, USA.
Purpose Of Review: The purpose of this narrative review is to describe the mechanisms for gut dysfunction during critical illness, outline hypotheses of gut-derived inflammation, and identify nutrition and non-nutritional therapies that have direct and indirect effects on preserving both epithelial barrier function and gut microbiota during critical illness.
Recent Findings: Clinical and animal model studies have demonstrated that critical illness pathophysiology and interventions breach epithelial barrier function and convert a normally commensal gut microbiome into a pathobiome. As a result, the gut has been postulated to be the "motor" of critical illness and numerous hypotheses have been put forward to explain how it contributes to systemic inflammation and drives multiple organ failure.
