The large and rapid increase in the incidence and mortality of colorectal cancer (CRC) demonstrates the urgent need for new drugs with higher efficacy to treat CRC. However, the lack of applicable and reliable preclinical models significantly hinders the progress of drug development. Patient-derived xenograft (PDX) models are currently considered reliable in vivo preclinical models for predicting drug efficacy in cancer patients.

Hyperforin, an active constituent from Hypericum perforatum, has been reported to inhibit inflammation. However, whether hyperforin may suppress CRC progression via inactivation of JAK/STAT3, ERK or AKT signaling remains unclear.

Near-infrared indocyanine green (ICG) fluorescence application in liver cancer surgery have been reported in the literature since 2008. To date, most reports emphasized not only to the safety, feasibility and reproducibility, but also the potential benefits of its clinical applications in term of demarcating segmentation for an anatomical resection, tumor identification to achieve tumor free resection margin, detection of small unidentifiable subcapsular nodules as well as extrahepatic metastatic lesions, and fluorescence cholangiography. The purpose of this review is to present the fundamental concept of the interpretation of fluorescence enhancement by different timing through intravascular ICG distribution to liver and biliary washout; to describe step-by-step technical aspects of its use in different purposes, and to expose the diagnostic and therapeutic perspectives of this innovative imaging technique in liver cancer surgery.

Most of these lesions are clinically silent and are found incidentally during laparotomy or endoscopic procedures for unrelated conditions. Symptomatic leiomyomas of the colon are encountered less frequently, with only sporadic reports in the literatures.

Heterotopic bone formation within an abdominal incision is a rare sequela of abdominal surgery. Only a few previous reports have noted heterotopic ossification in the mesentery of the small intestine and peri-ileostomy. Here, we report the case of a 60-year-old man who underwent emergent laparotomy and total colectomy with end ileostomy and developed this condition 1 month postoperatively.
