Background
Diabetes has been reported as a comorbidity of chronic obstructive pulmonary disease (COPD) in Western countries, but it has not been demonstrated in epidemiological reports in Japan. The purpose of this study was to clarify whether the relationship between airflow obstruction and diabetes can be confirmed in a Japanese general population.Methods
From 2004 to 2006, blood sampling and pulmonary function tests were performed on 3045 people over the age of 40 years in annual health check-ups held in Takahata, Yamagata Prefecture, Japan. Pulmonary function was re-evaluated in 2009 and 2011.Results
The prevalence of diabetes did not differ between subjects with and without airflow obstruction. Furthermore, although body mass index decreased, no increase in the prevalence of diabetes was observed with the progression of airflow obstruction. The annual changes in forced expiration volume in 1 s (FEV1) did not differ depending on the presence or absence of diabetes in the study population.Conclusion
There was no difference in the prevalence of diabetes between subjects with airflow obstruction and those without. As patients with COPD in Japan are thinner than in the West, diabetes may not be a common comorbidity in Japanese patients with COPD. 相似文献22.

A 51-year-old man had a reddish flat granular lesion in the stomach on endoscopic examination. Histology of biopsied specimen confirmed the diagnosis of low-grade B-cell gastric lymphoma of mucosaassociated lymphoid tissue (gastric MALT lymphoma) and simultaneous infection withHelicobacter pylori. He was given antibiotic treatment. Five weeks later, endoscopy and histology of biopsied specimen showed eradication ofH. pylori, and the tumor had regressed. Six months later,H. pylori reemerged, but the tumor had not recurred. After the second antibiotic therapy,H. pylori has been eradicated. The lymphoma has been in remission for 14 months. 相似文献

OBJECTIVES: The relation between the occurrence of pacing-induced mechanical alternans and prognosis in patients with mild-to-moderate idiopathic dilated cardiomyopathy (IDCM) in sinus rhythm was investigated prospectively. The myocardial expression of genes for Ca2+-handling proteins in such patients was also examined. BACKGROUND: Mechanical alternans occurs in some patients with severe heart failure, but the relation between the occurrence of mechanical alternans and prognosis in patients with IDCM has remained unknown. METHODS: Left ventricular (LV) pressure was measured during atrial pacing, and LV endomyocardial biopsy specimens were collected in 36 IDCM patients and 8 controls. Idiopathic dilated cardiomyopathy patients were divided into two groups consisting of 22 individuals who did not develop mechanical alternans at heart rates up to 140 beats/min (group A) and of 14 individuals who did (group B). The patients were followed up for a mean of 3.7 years. RESULTS: There was no significant difference in LV ejection fraction or the plasma concentration of brain natriuretic peptide between groups A and B. The myocardial abundance of ryanodine receptor 2 messenger ribonucleic acid (mRNA) was significantly lower in groups A and B than in controls, whereas that of sarcoplasmic reticulum Ca2+-ATPase mRNA was significantly lower in group B than in group A or controls. Stepwise multivariate analysis identified pacing-induced mechanical alternans as the strongest predictor of cardiac events. Event-free survival in group A was significantly greater than that in group B. CONCLUSIONS: The occurrence of pacing-induced mechanical alternans is a potentially useful indicator of poor prognosis in patients with mild-to-moderate IDCM in sinus rhythm. 相似文献

We observed the quantitative estimation of the transmural changes associated with gastric ulcer healing by using endoscopic ultrasonography (EUS). It was possible to diagnose the depth of ulcer by EUS. Forty-eight patients were divided into three treatment groups. Group A (n = 16) was treated with 800 mg cimetidine daily, group B (n = 22) with 20 mg omeprazole daily, and group C (n = 10) with 400 mg cimetidine + 300 mg gefarnate daily. EUS was performed before and after 2, 4, and 8 weeks of treatment. The groups were compared from the viewpoints of endoscopic findings and contraction rate of the length and the cross-sectional area of the ulcer in EUS pictures. The best healing of both the endoscopic and EUS findings was seen in group B. By estimating the changes inside the ulcer, EUS may provide useful information for choice of anti-ulcer agents. 相似文献

The coat protein (CP) gene of rice stripe virus was introduced into two japonica varieties of rice by electroporation of protoplasts. The resultant transgenic plants expressed the CP at high levels (up to 0.5% of total soluble protein) and exhibited a significant level of resistance to virus infection. Plants derived from selfed progeny of the primary transformants also expressed the CP and showed viral resistance, indicating stable transmission of the CP gene and the trait of resistance to the next generation. Moreover, the virally encoded strip disease-specific protein was not detected in transgenic plants expressing CP 8 weeks after inoculation, indicating protection before viral multiplication. These studies demonstrated that CP-mediated resistance to virus infection can be extended to cereals and to the viruses transmitted by an insect vector (planthopper). 相似文献

BACKGROUND: The present study examined the impact of an 8-week cardiac rehabilitation (CR) program on physiological outcomes and health-related quality of life (HRQOL) of patients with acute myocardial infarction (AMI). METHODS AND RESULTS: A total of 124 consecutive AMI patients were divided into a supervised outpatient CR group (n=82) and a non-CR group as a control (n=42). Peak oxygen uptake, handgrip strength, and knee extension muscular strength were used as physiological outcome measures. HRQOL outcomes were assessed by the Medical Outcome Study Short Form 36 (SF-36). CR group patients performed both aerobic exercise and moderate resistance training from 1 month (T1) to 3 months (T2) after AMI onset. Age, sex, body mass index, medications, and ejection fraction were similar in both groups. Significantly greater increases in overall physiological outcomes from T1 to T2 were measured in the CR group compared with those of the non-CR group. There were also significantly greater improvements in 4 of the 8 SF-36 health status subscales (physical functioning, role-physical, general health, and vitality) in the CR group compared with the non-CR group. CONCLUSIONS: Eight weeks of exercise training have specific effects on improvement in HRQOL and physiological outcomes in Japanese patients. 相似文献

BACKGROUND: Although genetic epidemiological studies have suggested that several genetic variants increase the risk for hypertension, the genes that underlie genetic susceptibility to this condition remain to be identified definitively. Large-scale association studies that examine many gene polymorphisms simultaneously are required to predict genetic risk for hypertension. METHODS and RESULTS: The population of the present study comprised 1,940 unrelated Japanese individuals, including 1,067 subjects with hypertension (574 men, 493 women) and 873 controls (533 men, 340 women). The genotypes for 33 single nucleotide polymorphisms of 27 candidate genes were determined with a fluorescence- or colorimetry-based allele-specific DNA primer-probe assay system. Multivariate logistic regression analysis with adjustment for age, body mass index, and the prevalence of smoking, diabetes mellitus, hypercholesterolemia, and hyperuricemia revealed that two polymorphisms (825C -> T in the G protein beta3 subunit gene and 190G -> A in the CC chemokine receptor 2 gene) were significantly associated with hypertension in men and that one polymorphism (-238G -> A in the tumor necrosis factor- alpha gene) was significantly associated with hypertension in women. CONCLUSION: These results suggest that two and one genes may be susceptibility loci for hypertension in Japanese men and women, respectively, and that genotyping of these polymorphisms may prove informative for prediction of the genetic risk for hypertension. 相似文献

BackgroundPulmonary metastasectomy (PM) for breast cancer-derived pulmonary metastasis is controversial. This study aimed to assess the prognostic factors and implication of PM for metastatic breast cancer using a multi-institutional database.MethodsClinical data of 253 females with pulmonary metastasis of breast cancer who underwent PM between 1982 and 2017 were analyzed retrospectively.ResultsThe median patient age was 56 years. The median follow-up period was 5.4 years, and the median disease-free interval (DFI) was 4.8 years. The 5- and 10-year survival rates after PM were 64.9% and 50.4%, respectively, and the median overall survival was 10.1 years. Univariate analysis revealed that the period of PM before 2000, a DFI <36 months, lobectomy/pneumonectomy, large tumor size, and lymph node metastasis were predictive of a worse overall survival. In the multivariate analysis, a DFI <36 months, large tumor size, and lymph node metastasis remained significantly related to overall survival. The 5- and 10-year cancer-specific survival rates after PM were 66.9% and 54.7%, respectively, and the median cancer-specific survival was 13.1 years. Univariate analyses revealed that the period of PM before 2000, DFI <36 months, lobectomy/pneumonectomy, large tumor size, lymph node metastasis, and incomplete resection were predictive of a worse cancer-specific survival. Multivariate analysis confirmed that a DFI <36 months, large tumor size and incomplete resection were significantly related to cancer-specific survival.ConclusionsAs PM has limited efficacy in breast cancer, it should be considered an optional treatment for pulmonary metastasis of breast cancer. 相似文献
