Introduction

Clinical engineering is a new interdisciplinary field that integrates engineering and medicine, and CE is a relatively new profession among medical professionals. In this field, it is important to combine engineering disciplines and medicine to effective therapy.
Our goal is to foster clinical engineers with advanced expertise and a scientific research mind based on knowledge and technological skills.
 

Education

We teach courses in the field of clinical engineering, which involves the operation and control of medical devices such as hemodialysis, extracorporeal cardiopulmonary bypass, and ventilators. We also provide practical training in subjects related to clinical engineering technology. Before the clinical training at the hospital, we check if the students have mastered the basic clinical skills. The OSCE (Objective Structured Clinical Examination) conducted in clinical engineering education includes the confirmation of communication skills. The purpose of this is to ensure that the student is able to communicate with the medical team as well as the basic skills. This is a very important part of the program. We believe that one of the most important skills for students who want to become clinical engineers is the ability to work in cooperation with other medical staff.

Research

Various research projects which related clinical engineering performed in our labo, specifically, the effect of extracorporeal circulation on living body; the effect of redox state of body fluid components on somatic cells; construction of regenerative medicine using the interaction between polymeric materials and cells; the rapid diagnostic method using isothermal amplification for myocardial infraction (see below for detailed research theme).
Each student in the fourth year selects one of the research projects, acquiring skills for research and development and engaging in academic activities.

1. Best Practices for Safe Extracorporeal Circulation The following studies are currently being conducted.

1) Research and study on standardization for safe extracorporeal circulation (2015-)
2) Evaluation of the current status of technology provision using extracorporeal circulation case registry data (2015-)
3) Research on objective evaluation of the effects of extracorporeal circulation(2015-)

Masaru Ihira / Yasuko Enya

1. Development of a rapid detection method for miRNAs by isothermal amplification.
2.The natural history of Human herpesvirus 6 (HHV-6)
3. The relationship rotavirus vaccine efficacy and the intestinal microbiome.

Principle of Iso-RAM

1. Development of a rapid detection method for miRNAs by isothermal amplification.

MicroRNAs (miRNAs) are from 20 -25 nucleotides of small non-coding RNAs that are involved in regulating a range of developmental and physiological processes; their dysregulation has been associated with the development of diseases. Therefore, the circulating miRNAs and exosomal miRNAs in blood have been proposed as being useful in diagnostics as biomarkers for diseases. However, However, there is no simple and rapid method to measure miRNAs. It requires expensive equipment, such as a real-time PCR machine or Next-generation sequencing. Our goal is to develop a simple and rapid diagnostic method for miRNAs using Rolling circle amplification (RCA) based on isothermal amplification technology.

2. The natural history of Human herpesvirus 6(HHV-6)

Human herpesvirus 6 was isolated from peripheral blood mononuclear cells from AIDS in 1986. HHV-6 is divided into 2 viruses which are named human herpesvirus 6A and 6B. HHV-6B primary infection is the cause of the common childhood illness exanthema subitum. The HHV-6B reactivation is common in transplant recipients, which can cause several clinical manifestations such as encephalitis, bone marrow suppression, and pneumonitis. Recently, we focused on chromosomally integrated human herpesvirus 6 (ciHHV-6). The ciHHV-6 was explained as HHV-6 genome integrated to chromosome. The frequency of ciHHV-6 is 0.6% in Japan. Our lab investigates how ciHHV-6 occurs and the relationship of clinical manifestation.

3. The relationship rotavirus vaccine efficacy and the intestinal microbiome

Rotavirus(RV) commonly causes severe, watery diarrhea and vomiting in infants and young children. Most children who get the vaccine will protect from RV severe disease. However, the vaccine efficacy against severe RV gastroenteritis ranging from 48-64% in developing countries is low compared to 85-98% in developed countries. There are several hypotheses as to Why oral RV vaccines are less effective in developing countries. One of the hypotheses is intestinal microbiome may be modulating an infant immune response to oral RV vaccine. Our lab investigates the relationship between RV viral load and the intestinal microbiome. Our DATA may be suggested that the suitable intestinal environment contributes to the immune response by RV vaccine strain amplification in the gut.

Atsushi Ohashi

1. Elucidation of the interaction between various blood purification devices and body fluid components
2. Development and evaluation of blood purification equipment

We analyze the pathophysiology of hemodialysis patients using laboratory analysis techniques. Specifically, we are studying oxidative stress caused by the biocompatibility of blood with medical materials and therapeutic devices.

Kazunori Kawaguchi

1．Novel therapeutic approach for Alzheimer's disease

To investigate whether the removal of blood Aβ affect cognitive functions and Aβ burden in the brain, we studied 1) the cognitive states and plasma Aβ levels of renal failure patients with/without hemodialysis (HD), and 2) Aβ depositions of postmortem brains of hemodialysis patients for creation of Extra-corporeal Aβ Removal System (EARS) as a novel therapeutic method of Alzheimer’s Disease.

Hideo Hori

1. Creation of kidney regeneration device using interaction between polymer materials and cells

End-stage kidney disease occurs when chronic kidney disease reaches an advanced state. In end-stage renal disease, your kidney function is almost lost. End-stage kidney disease requires renal replacement therapy such as hemodialysis. In Japan, more than 340,000 patients undergo hemodialysis, and there are various issues such as quality of life and medical expenses. Therefore, we are developing a kidney regeneration device using polymer materials and cells to prevent end-stage renal disease.　(Hideo Hori)
