Current and Past Project
  • The vacuole called exosome which cancer associated fibroblast which is important to cancer progress secretes out of the cell contains a great variety of unknown protein and mRNA or miRNA, but is unexplained about the detailed functional significance. CAF brought EMT of the cancer cell through exosome and might take an important role of the increase permeation of cancer and thought that this mechanism elucidation was connected for the innovative cure that controlled new liver cancer increase permeation, and an original idea did this study. The purpose of this study elucidates cancer increase permeation mechanism through exsome of CAF in the liver cancer and is that an original idea does new liver cancer treatment. The role of exosome which CAF of the liver cancer which it is hard to control secretes is unexplained, and the mechanism is unreported and thinks that there are originality and originality. I analyze the influence on liver cancer strain of separation exosome and an expression of miRNA and mRNA change with the microarray and analyze liver cancer progress permeation ability by these expression control and am going to elucidate mechanism.
  • In a specimen to hepatectomy of hepatocellular carcinoma, is easy to have vessels permeation with HCC subtype to exist a special blood vessel pattern to be surrounded with more sinusoid-like vasculature, and a no recurrence survival rate is bad after art; this EMT (Hepatology, 2015, 62; 452-65) that were reported when caused blood circulation metastasis and remote metastasis independently. There is much metastasis remoter than the recurrence in the liver, and remote metastasis controls convalescence as a recurrence form after a live donor liver transplant for the liver cancer. I examine HCC subtype and a liver cancer recurrence form.

1. 原田 昇, Bacteremia; Risk Factors, Treatment and Potential Complications, 2014.08, Bacterial sepsis is frequent occurrences during the first 1 to 2 months after liver transplantation under the immunosuppressive therapy. Despite recent advances in perioperative management and surgical techniques, postoperative mortality and morbidity rates are still associated with infectious complications such as bacterial sepsis after liver transplantation. Furthermore, bacterial sepsis is the most frequent cause of in-hospital death after living donor liver transplantation (LDLT).
In this section, we discuss the etiology, outcomes, and risk factors of bacterial sepsis after LDLT, and we focus on the impact of the perioperative nutritional support in LDLT to prevent bacterial sepsis after LDLT. Compared with deceased donor liver transplantation, LDLT involves smaller graft size and scheduled nonemergent surgery. The smaller graft size is the main disadvantage of adult-to adult LDLT because it results in increased portal venous pressure, impaired bowel motility, bacterial translocation, ascites production, and hyperbilirubinemia.
In the last 2 decades, nutritional support has been recognized as a vital component for the management of critically ill patients, by delivering preoperative essential substrates, and nutrition by using enteral feeding, to aid patient recovery. In particular, preoperative branched-chain amino acid (BCAA) supplementation might reduce the incidence of postoperative bacterial sepsis after LDLT, and early enteral nutrition was associated with significantly reduced risk of developing bacterial sepsis after LDLT.
In this way, poor nutritional status of the pretransplants can be improved by using preoperative nutritional support and high infectious status of the posttransplants under immunosuppressive therapy can be improved with initiation of the early postoperative enteral nutrition. Improved nutrition supports a functional immune system and reduces septic morbidity and mortality in patients with liver transplantation. .

Noboru Harada, Surgical Resection for hepatocellular carcinoma with Concomitant Esophageal Varices., World Journal of Surgery, 10.1007/s00268-015-3110-9, 39, 10, 2510-2518, 2016.02, Background: The aim of this study was to compare the outcome of patients with hepatocellular carcinoma (HCC), Barcelona Clinic Liver Cancer (BCLC) stages 0 and A, and portal hypertension (PHT) who underwent liver resection (LR) or radiofrequency ablation (RFA).Methods: The study population consisted of 121 patients with PHT and HCC of BCLC stage 0 and A who underwent LR (n=81) or RFA (n=40). To reduce bias in patient selection, the different covariate distributions in the two groups were adjusted using inverse probability treatment weighting (IPTW). The prognostic outcomes of LR- and RFA-treated patients were then analyzed.
Results: Before IPTW adjustment, the 5-year overall survival (OS) of LR and RFA patients was comparable. Five-year recurrence-free survival (RFS) was significantly better in the LR group than in the RFA group (P < 0.0001). Multivariate analysis showed that RFA was an independent predictor of worse RFS (P = 0.0004). The RFA group had more local recurrences rates than the LR group and each group had tendency to perform the same treatment modality as the firstline one after recurrence. After IPTW adjustment, the OS of patients in the LR and RFA groups did not significantly differ, whereas the RFS of the LR group remained significantly better than that of the RFA group (P=0.00014). However, the RFA group had fewer postoperative complication rates and a shorted length of hospital stay. Conclusions: By taking care of the postoperative complications, LR may be a treatment option for patients with BCLC stage 0 or A HCC and PHT..
