We report a case of chronic localized thoracoabdominal aortic dissection with an entry located just above the celiac artery which was successfully treated by patch aortoplasty. The patient was a 55-year-old man who complained of abdominal and back pain. CT scan and angiography showed a localized thoracoabdominal aortic dissection the entry of which was located just above the celiac artery. The patient underwent resection of the aneurysm and patch aortoplasty with the aid of a femoro-femoral bypass. The postoperative course was uneventful. Localized thoracoabdominal aortic dissection has been reported in only 5 cases, including our case, in the Japanese literature.

Physiological responses to heat and heat tolerance were examined in summer and winter on 13 male athletic university students and male nonathletec university students. After staying for 30 min. in a climatic chamber maintained at 30°C with 70% relative humidity, sweating reaction was examined far 90 min, by immersing both legs up to the knees in a stirring water bath of 42°C.
Both groups showed significantly greater sweat volume, significantly lower Na concentration in sweat and considerably lower rise in rectal temperature and less increase in heart rate in summer than in winter. In both seasons, athletes showed smaller volume of sweat, lower Na concentration in sweat, lower rise in rectal temperature and less increase in heart rate than nonathletes.
It is concluded that heat tolerance of athletes was superior to that of nonathletes when assessed by our heat tolerance indices and this superior heat tolerance of athletes could be explained due to a result of physical training. Heat tolerance index, representing the magnitude of physiological strain in the body induced by heat load, was modified by using relative increase in heart rate in place of salt loss. It can be said that the modified heat tolerance index is useful as a substitute of the original heat tolerance index in field studies.

OBJECTIVE: Schizophrenia is a mental disorder characterized by severe cognitive impairment. Accumulating evidence suggests a role for oxidative stress in the pathophysiology of schizophrenia. Sulforaphane (SFN) extracted from broccoli sprout is an agent with potent anti-oxidant and anti-inflammatory activity. In this study, we attempted to evaluate the effect of SFN on cognitive impairment in medicated patients with schizophrenia. METHODS: We recruited a total of 10 outpatients with schizophrenia, all of whom gave informed consent. Participants took 3 tablets of SFN, consisting of 30 mg of SFN-glucosinolate per day, for 8 weeks. Clinical symptoms using the Positive and Negative Syndrome Scale (PANSS) and cognitive function using the Japanese version of CogState battery were evaluated at the beginning of the study and at week 8. RESULTS: A total of 7 patients completed the trial. The mean score in the Accuracy component of the One Card Learning Task increased significantly after the trial. However, we detected no other significant changes in participants. CONCLUSION: This result suggests that SFN has the potential to improve cognitive function in patients with schizophrenia.

The purpose of this study was to examine the relationship of the Rohrer index and physical activity on motor function. The subjects were 143 elementary school children in the 5th and 6th grades. Motor function was measured based on musculoskeletal examination. The Rohrer index was calculated from height and weight, and ≥140 was defined as a tendency to be overweight. Physical activity was investigated using a self-reported questionnaire, the WHO Health Behaviour in School-aged Children in Japanese version (HBSC-J). A total of 130 students and their parents agreed to participate in this study, and the data of 127 students were analyzed. The main results were as follows: 26 students had a Rohrer index ≥140, and 60 students (47.2%) had abnormalities in one or more items of motor function. In particular, there were many who reported “Impossible to fully squat” and “Limitation of standing forward flexion”. When compared by sex, “Impossible to fully squat”, “Limitation of standing forward flexion”, and “Pain in shoulder” were particularly frequent in boys. The Rohrer index was particularly high in those who reported that it was “Impossible to fully squat”, but it was not associated with HBSC-J. “Impossible to fully squat” was particularly low in HBSC-J (days of Moderate to vigorous Physical Activity and frequency of Vigorous Physical Activity). The results suggested that children of impossible to fully squat is a lot of low activity and obesity. In conclusion, children who are unable to squat should be followed up to promote physical activity and improve obesity.

OBJECTIVE: Programmed cell death-ligand 1 (PD-L1) is expressed in tumor cells and has been shown to predict clinical outcomes of several types of malignancies. The aim of this study was to investigate the effects of carbon-ion (C-ion) beam irradiation on PD-L1 expression in human uterine cervical adeno/adenosquamous carcinoma (UCAA) cells and clinical samples and to identify the prognostic factors for outcomes after C-ion radiotherapy (CIRT).METHODS: The effects of C-ion irradiation on PD-L1 expression in human UCAA and cervical squamous cell carcinoma cells were examined by flow cytometry. We examined PD-L1 expression in UCAA biopsy specimens from 33 patients before CIRT started (pre-CIRT) and after 12 Gy (relative biological effectiveness [RBE]) irradiation (post-12Gy-C) in 4 fractions of CIRT to investigate the correlation between PD-L1 status and clinical outcomes.RESULTS: The PD-L1 expression was upregulated by C-ion beam in a dose-dependent manner in HeLa and SiHa cells through phosphorylated Chk1. The overall frequencies of pre-CIRT and post-12Gy-C PD-L1 positivity were 45% (15/33) and 67% (22/33), respectively. The post-12Gy-C PD-L1 expression was significantly elevated compared to the pre-CIRT PD-L1 expression. There was no significant relationship between the pre-CIRT PD-L1 status and clinical outcomes, such as local control (LC), progression-free survival (PFS), and overall survival (OS). However, the post-12Gy-C PD-L1 expression had better correlation with PFS, but not with LC and OS.CONCLUSION: CIRT can induce PD-L1 expression in UCAA and we propose that PD-L1 expression after starting CIRT may become as a predictive prognostic marker in CIRT for UCAA.
