AIM To investigate safety and oncological feasibility of laparoscopic total gastrectomy(LTG) in overweight(OW) *** Patients who underwent total gastrectomy(110 laparoscopic, 211 open) for gastric cancer between January 1999 and July 2016 were included. Propensity score matching selected 152 patients(76 laparoscopic, 76 open), which were subsequently divided into the OW(≥ 25) or non-OW(< 25) group by body mass index. Postoperative outcomes of laparoscopic versus open approaches were compared between OW and non-OW groups. RESULTS In the propensity-matched population, baseline characteristics were comparable between the OW and nonOW groups for the laparoscopy and open groups. In the laparoscopy group, operative time was longer(P = 0.01) in the OW group, however, other perioperative results including complication rates were comparable between the non-OW and OW groups. In the open group, number of retrieved lymph nodes were less(P = 0.03) and local complication rate was more frequent(P = 0.03) in the OW group. CONCLUSION LTG in OW patients remains technically challenging but can be performed safely. Our findings imply that OW has a lesser effect on the laparoscopic versus open approach to total gastrectomy.

Hepatocellular carcinoma(HCC) is the fifth most common cancer, and obesity has been established as a risk factor for HCC development. Nonalcoholic steatohepatitis(NASH) is apparently the key link between obesity and hepatocarcinogenesis, and obesity also accelerates HCC development synergistically with other risk factors, such as hepatitis virus infection and alcohol consumption. As an explanation for the pathogenesis of NASH, the so-called "two-hit" theory has been widely accepted, but recently, a better model, the so-called "multiple-hits hypothesis" was proposed, which states that many disease-promoting factors may occur in parallel, rather than consecutively. However, the overall mechanism remains largely unknown. Various cell-cell and organ-organ interactions are involved in the pathogenesis of NASH, and thus appropriate in vivo disease models are essential for a deeper understanding. However, replicating the full spectrum of human NASH has been difficult, as NASH involves obesity, insulin resistance, steatohepatitis, fibrosis, and ultimately HCC, and the lack of an appropriate mouse model has been a considerable barrier to determining the missing links among obesity, NASH, and HCC. In recent years, several innovative mouse models presenting obesity- and NASHassociated HCC have been established by modified diets, chemotoxic agents, genetic manipulation, or a combination of these factors, shedding some light on this complex network and providing new therapeutic strategies. Thus, in this paper, I review the mouse models of obesity- and NASH-associated HCC, especially focusing on recent advances and their clinical relevance.

To study the screening effect of nuclear reactions in metallic environments, the thick target yields, the cross sections and the experimental S（E） factors of the D（d, p）T reaction have been measured on deuterons implanted in Sm metal at 133.2K for beam energies ranging from 10 to 20 ke V. The thick target yields of protons emitted in the D（d, p）T reaction are measured and compared with those data extrapolated from cross sections and stopping power data at higher energies. The screening potential in Sm metal at 133.2K is deduced to be 520±56eV. As compared with the value achieved in the gas target, the calculated screening potential values are much larger. This screening potential cannot be simply interpreted only by the electron screening. Energy dependences of the cross section σ（E） and the experimental S（E） factor for D（d,p）T reaction in Sm metal at 133.2K are obtained, respectively.

The COPD Assessment Test was recently developed to assess health status in patients with COPD. However, little was known about its application to patients with interstitial lung disease, so we examined the relationship between the COPD Assessment Test score and respiratory impairment including the clinical picture in subjects with interstitial lung disease. Data were collected retrospectively from 52 consecutive subjects with interstitial lung disease on admission to our facility. All subjects completed the COPD Assessment Test, in which a higher score represented a worse health status. They were also assessed by pulmonary function test, SpO2 during 6-min walk test, and arterial blood gases. The COPD Assessment Test score was negatively correlated with the percentage of predicted forced vital capacity, forced expiratory volume in 1 second, total lung capacity, diffusion capacity of the lung for carbon monoxide, and PaO2 (p = 0.0005, 0.005, 0.0002, 0.0005, and 0.002, respectively). Breathlessness was detected as the high scoring item, while phlegm and sleep were the last affected items. The COPD Assessment Test score was higher in subjects with oxygen desaturation in SpO2 (≥4%) during 6-min walk test (p = 0.0001) and in subjects on home oxygen therapy (p = 0.0007). More than 75% of subjects with oxygen desaturation during walking were classified into a medium or severer impact level of the COPD Assessment Test score, and subjects on home oxygen therapy were classified into a high or severer impact level. PaCO2 in room air and SpO2 at rest did not correlate with the COPD Assessment Test score. The reliability of items in the COPD Assessment Test was 0.87 by Cronbach’s α coefficient. Our results suggest that the COPD Assessment Test may be a candidate for evaluating the health status and impact of disease on patients with interstitial lung disease.

In order to expand the natural energy and the energy conservation, ＂the smart PV （photovoltaic power generation）＆ EV （electric vehicle） system＂ has been proposed and the effect has been clarified. In the smart PV ＆ EV system, it is important that electric vehicles become popular. Therefore, the AI-EV （air-conditioner integrated electric vehicle） has been proposed. In this paper, the AI-EV is designed based on the required car air-conditioner capacity. And, the value of AI-EV is compared with a gasoline vehicle, HV （hybrid vehicle） and EV using the mathematical simulation model As a result, it is clarified that the minimum displacement of the small-engine is 120 cc for AI-EV. In the smart PV ＆ EV system, AI-EV can reduce CO_2 emissions by 20% almost the same as EV. Additionally, AI-EV is able to gain the cruising range more than twice as long as EV.

In order to make maximum use of the EV （electric vehicle） battery, evaluating the remaining battery capacity and the power consumption is important. Evaluation method of the remaining battery capacity with accuracy has been proposed. Moreover, the evaluation method of the power consumption for traveling has been proposed. However, the power consumption for vehicle-mounted air-conditioner is 30%. It is necessary to calculate the power consumption for both traveling and air-conditioning. In this paper, the authors have constructed a mathematical model which calculates the EV power consumption for both traveling and air-conditioning. The calculated results of this model have been compared to actual traveling data. In addition, factors which have a impact on the EV power consumption have been studied. As a result, the EV power consumption is greately varied by slope resistance, acceleration resistance and required air-conditioning load. Moreover, it is clarified that the air-conditioner consumes approximately 25% to 50% of the total power consumption in a hot summer day. In addition, the acceleration and the air-conditioning load differ depending on each vehicle driver. Therefore, in order to evaluate the EV power consumption practically, it is necessary to reflect the characteristics of each vehicle driver.
