Abstract
Annual influenza vaccination is strongly recommended for patients with chronic pulmonary diseases, such as bronchial asthma, chronic obstructive pulmonary disease (COPD), and interstitial pulmonary diseases. However, many of these patients regularly receive systemic and/or inhaled corticosteroid therapy, and the impact of corticosteroid therapy on influenza vaccine efficacy and safety is unclear. Patients with chronic pulmonary diseases were enrolled in the study and divided into three groups based on their maintenance therapy: (A) without corticosteroid therapy (17 males, three females; mean age, 72.3 ± 7.9), (B) oral corticosteroid therapy (four males, seven females; mean age, 66.1 ± 10.6), and (C) inhaled corticosteroid therapy (eight males, nine females; mean age, 62.4 ± 16.0). All patients received influenza vaccine, and serum hemagglutination inhibition (HI) antibodies against influenza strains A/H1N1, A/H3N2, and B were measured at baseline (before vaccination) and 4-6 weeks after vaccination. Sufficient antibody titers or significant increases were observed after vaccination compared with titers before vaccination in all three groups. No systemic reactions were reported. Long-term oral/inhaled corticosteroid therapy was not associated with vaccination side effects and did not affect the immune response to the influenza vaccine.

Abstract
BACKGROUND AND PURPOSE LIT-MCD is used in our institution for acute stroke due to MCA occlusion, with the goal of reducing symptomatic intracranial hemorrhage by maintaining recanalization of the occluded vessels. The purpose of the study was to investigate the safety and efficacy of LIT-MCD and to identify factors associated with a poor outcome in patients undergoing this procedure. MATERIALS AND METHODS LIT-MCD for MCA occlusion was performed in 90 of 1907 consecutive patients with acute stroke admitted to our institution. Radiographic data and clinical outcome were evaluated in the 90 patients, and factors predictive of a poor outcome (3-month mRS score, 3-6) were investigated by multivariate analysis. RESULTS Recanalization was achieved in 73 of the 90 patients (81%); symptomatic intracranial hemorrhage occurred in 7 (8%); procedure-related complications, in 9 (10%); and a favorable clinical outcome (3-month mRS score, 0-2), in 48 (53%). A high baseline NIHSS score (≥20), a low preprocedural ASPECTS on MR imaging (≤7), proximal M1 occlusion (in the horizontal segment of the MCA at or proximal to the lenticulostriate arteries), and no recanalization were significant predictors of a poor clinical outcome. CONCLUSIONS LIT-MCD is a safe and effective treatment for acute stroke due to MCA occlusion. However, further intervention is needed to improve the outcome of patients with proximal M1 occlusion.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is characterized by chronic airflow limitation. The prevalence of airflow limitation in Japan is 10.9% (16.4% of males and 5.0% of females). Cigarette smoking is well known as a major cause of COPD. However, few epidemiological studies have evaluated the effects of cigarette smoking on pulmonary function in healthy subjects. METHODS Subjects aged 40 years or older (n=2,917), who had participated in a community-based annual health check in Takahata, Japan, from 2004 through 2005, were enrolled in the study. The smoking histories of these subjects were investigated using a self-reported questionnaire. Forced vital capacity (FVC), forced expiratory volume in 1 second (FEV(1)), and forced expiratory flow at 25-75% of FVC (FEF(25-75)) were measured by standard procedures using spirometric machines. RESULTS There were 554 current smokers (18.6%) and 403 former smokers (13.8%). The prevalence of airflow limitation defined by FEV(1)/FVC <0.7 in this population was 10.6%, and prevalence of airflow limitation defined by 5th percentile lower limit of normal was 6.4%. In smokers, percent predicted values of measured spirometric parameters (%FVC, %FEV(1) and %FEF(25-75)) decreased significantly with age, except for male %FVC. Also, percent predicted values of measured spirometric parameters decreased significantly with increasing pack-years, except for female %FEF(25-75). CONCLUSION Cigarette smoking increased the prevalence and severity of airflow limitation. It is concluded that cigarette smoking increases the risk of airflow limitation in a healthy Japanese population.

Abstract
We investigated the potential usefulness of vesnarinone, a novel cytokine inhibitor, for the treatment of lung fibrosis using a murine model of bleomycin (BLM)-induced pulmonary fibrosis. Mice were fed a control diet (n=42), or a diet containing low (n=42) or high (n=42) dose of vesnarinone. Dietary intake of vesnarinone minimized the BLM toxicity as reflected by significant decreases in numbers of inflammatory cells, KC, and soluble TNF receptors in the bronchoalveolar lavage fluid. A quantitative evaluation of histology demonstrated significantly mild lung parenchymal lesions in BLM-treated mice fed with diet containing high dose of vesnarinone than in the control diet group. Consistent with the histopathology, hydroxyproline levels in lung tissue from BLM-treated mice fed with diet containing vesnarinone were significantly lower than that from mice fed with control diet. We concluded that vesnarinone inhibits BLM-induced pulmonary fibrosis, at least in part, by the inhibition of acute lung injuries in the early phase.

Abstract
BACKGROUND The Gly80Ser polymorphism in phospholipase A2-IID (PLA2G2D, NCBI SNP reference: rs584367) is associated with a loss in body weight in patients with chronic obstructive pulmonary disease (COPD). The T allele missense mutation results in the 80th amino acid of the PLA2G2D protein changing from a glycine (Gly; C allele) to a serine (Ser; T allele). COPD patients carrying Ser lose a significant amount of weight compared with those carrying Gly. The mechanism for this weight loss following carriage of this Ser allele has not been clarified. OBJECTIVES We aimed to evaluate whether this allelic change alters PLA2 enzymatic activity and/or pro-inflammatory cytokine inducibility. METHODS A549 cells (a human pulmonary epithelial cell line) were transfected with PLA2G2D-Gly or PLA2G2D-Ser. We evaluated PLA2 activity and cytokine expressions in these cells. RESULTS The enzymatic activity of sPLA2 in A549-PLA2G2D-Ser cells did not differ from the A549-PLA2G2D-Gly cells. A549-PLA2G2D-Ser cells spontaneously produced higher levels of interleukin (IL)-6 and IL-8 than A549-PLA2G2D-Gly cells. Upon tumor necrosis factor-alpha stimulation, IL-6 and IL-8 mRNA and protein levels in A549-PLA2G2D-Ser cells were elevated compared with those of A549-PLA2G2D-Gly cells. Upon hydrogen peroxide stimulation, IL-8 mRNA and protein levels in A549-PLA2G2D-Ser cells were higher than those of A549-PLA2G2D-Gly cells. CONCLUSIONS PLA2G2D-Ser enhances the expression of IL-6 and IL-8 compared with PLA2G2D-Gly. This enhanced cytokine expression observed with the allelic change in PLA2G2D may be associated with the body weight loss seen in COPD patients.

Abstract
BACKGROUND AND OBJECTIVE The natural history of COPD, a disease usually caused by cigarette smoking, is associated with frequent respiratory infections. Consistent with human COPD, bacterial clearance in the lungs has been reported to be impaired in mice exposed to cigarette smoke. In the airways, several antimicrobial molecules such as surfactant proteins (SP), beta-defensins (BD), secretory leucocyte protease inhibitor (SLPI) and lysozyme play important roles in the defence against invading pathogens. This study evaluated the expression of antimicrobial molecules in mice lungs with cigarette smoke-induced emphysematous changes. METHODS Six B6C3F1 mice were exposed to cigarette smoke (2 cigarettes/day/mouse for 6 months) or room air. Gene expression within the lungs of mice in both groups was assessed by RT-PCR. RESULTS The expression of SP-A, BD2, BD3 and SLPI was significantly elevated in the lungs of cigarette smoke-exposed mice compared with air-exposed mice. BD1 expression decreased in the smoke-exposed mice and lysozyme expression was unchanged. CONCLUSIONS Chronic cigarette smoke exposure did not suppress the expression of antimicrobial molecules in the lung. Altered expression of antimicrobial molecules in this mouse model does not explain the impaired host defence against respiratory microbes seen in patients with COPD.

Abstract
BACKGROUND AND OBJECTIVE Pulmonary emphysema is associated with frequent respiratory infections but little is known about the reasons for this susceptibility to bacterial infection. We previously demonstrated an impaired inflammatory response to Streptococcus pneumoniae in an experimental emphysema mouse model at 24 h, or longer following bacterial inoculation. Toll-like receptors (TLR) have been recognized as regulators in the inflammatory response. We examined the expression of TLR on alveolar macrophages in experimental emphysema mice and evaluated the immediate inflammatory response of the emphysematous lung to streptococcal infection. METHODS Elastase was administered once into mice trachea to induce pulmonary emphysema. Three weeks later, expression of TLR-2 and TLR-4 in the BAL cells was examined by immunostaining. Following the intratracheal inoculation of Streptococcus pneumoniae, pro-inflammatory cytokine concentrations were measured in the BAL fluids of the control and emphysema mice. RESULTS The expression of TLR-2 and TLR-4 was significantly elevated in the alveolar macrophages of emphysema mice. Six hours after infection, neutrophils in the BAL fluid of emphysema mice were significantly increased, and the levels of tumour necrosis factor-alpha, IL-1beta and IL-6 were significantly elevated, compared with the control mice. At 3 h post inoculation, macrophage inflammatory protein-2 levels were significantly elevated. CONCLUSIONS The immediate inflammatory response in the emphysematous lung is significantly enhanced in response to streptococcal infection. This may be partly attributed to the increased expression of TLR in the alveolar macrophages of emphysema mice.

Abstract
Albuminuria is an early marker of vascular damage, and its development in diabetic nephropathy is associated with genotype of inflammatory CC chemokine ligand 5 (CCL5). This study investigated whether the association of CCL5 and albuminuria is a general phenomenon. We characterized a Japanese population consisting of 2,749 non-diabetic individuals over 40 years in Takahata, Japan. The urine albumin-creatinine ratio (UACR) was obtained from morning spot urine. We genotyped SNPs within the CCL5 gene that displayed frequent minor allele frequencies in Japanese (i.e., rs2107538, rs2280789, rs3817655 and rs9909416). Assessment of possible association and linkage disequilibrium (LD) revealed that all four SNP genotypes are correlated significantly with UACR (P = 0.004-0.005), and these four SNPs variations showed an obvious consistency of genotypes by detecting almost complete linkage disequilibrium (D' = 1 and r (2) > 0.95). We found two exclusive haplotypes in the CCL5 gene (haplotype1: rs2107538G/rs2280789T/rs3817655T/rs9909416G, frequency 0.64 and haplotype2: rs2107538A/rs2280789C/rs3817655A/rs9909416A, frequency 0.35) among the population. A significant association with elevated UACR was identified with haplotype1 (P = 0.002). Homozygotes for haplotype1 displayed strikingly-elevated UACR (48.5 +/- 6.6 mg/g, n = 1,116) compared to the rest (28.6 +/- 1.6 mg/g, n = 1,530) (P = 0.001). In conclusion, these results suggested that genetic variation of CCL5 might be an important risk factor for albuminuria in the non-diabetic Japanese general population.

Abstract
BACKGROUND AND PURPOSE The clinical outcome is often poor in acute stroke patients with a serious neurological status due to occlusive lesions of the intracranial vertebral and/or basilar artery (IVBA). The purpose of this study was to investigate retrospectively the clinical features and outcome of acute stroke patients who underwent transluminal angioplasty and/or stenting (TAS) for occlusive lesions of the IVBA and to clarify the prerequisites for improvement of outcome. MATERIALS AND METHODS Of 1690 consecutive acute ischemic stroke patients admitted to our institution, TAS for occlusive lesions of the IVBA was performed within 7 days after stroke onset in 28 patients. We classified these patients into 2 groups, those with total occlusion (occlusion group) and those with a high-grade stenosis (stenosis group), and compared the preprocedural neurologic status (severe: National Institutes of Health Stroke Scale >20), the rate of technical success, major procedure-related complications, subacute occlusion of the treated vessel, and favorable clinical outcome (0-2 points on a 3-month modified Rankin Scale) between the 2 groups. RESULTS In the occlusion group (n = 16) and stenosis group (n = 12), a severe preprocedural neurologic status was seen in 13 and 1 patients, respectively (81% versus 8%; P = .0001); technical success was achieved in 13 and 11 patients, respectively (81% versus 92%; P value not significant [NS]); complications occurred in 6 and 0 patients, respectively (38% versus 0%; P < .05); subacute occlusion was seen in 4 and 1 patients, respectively (25% versus 8%; P = NS); and a favorable clinical outcome was obtained in 3 and 9 patients, respectively (19% versus 75%; P < .01). CONCLUSION The clinical outcome of patients who underwent TAS for total occlusion of the IVBA was poor. Improvement of outcome requires reduction of procedure-related complications and subacute occlusion.

Abstract
The forced expiratory volume in the first second (FEV1.0)/the forced vital capacity (FVC) is an important index of a single forced expiration. Ectopic expression of the human olfactory receptor (OR) gene family in the lungs has suggested its potential involvement of respiratory physiology. We hypothesized that the individual variability of FEV1.0/FVC value may be attributed to the genetic variance of the OR gene family caused by the nonfunctioning SNPs (nSNPs). We conducted quantitative trait locus (QTL) analyses of population having the 7 OR gene nSNPs and FEV1.0/FVC values by ANOVA, in 2970 samples in the Yamagata Takahata cohort. We found significant association of one nSNP [rs10838851, OR, family 4, subfamily X, member 1 (OR4X1) gene, Tyr273Ter*] with FEV1.0/FVC (%) (P = 0.008). The FEV1.0/FVC value (%) of population having OR4X1 gene nSNP Ter*/Ter*, Ter*/Tyr, and Tyr/Tyr were 78.9 +/- 0.2, 78.2 +/- 0.2, and 77.7 +/- 0.4, respectively. Haplotype-based analysis of the OR4X1 gene with FEV1.0/FVC values demonstrated that two exclusive haplotypes [Hap-1/Hap-2 (frequency 0.669/0.330): SNP1 (rs7106648)T/A-SNP2 (rs871249)G/A-SNP3 (rs713325)G/A-SNP4 (rs10838851)A (Ter*)/T (Tyr)-SNP5 (rs4752923)G/A-SNP6 (rs960640)G/A] were significantly associated with FEV1.0/FVC values (global P = 0.005). These results suggest that OR4X1 may be one of the genes that contribute to the individual variability of FEV1.0/FVC value in pulmonary function test.

Abstract
BACKGROUND Brain natriuretic peptide (BNP) has been widely used for the diagnosis and prognostic evaluation of chronic heart failure (CHF). In the present study, we performed association study of single nucleotide polymorphisms (SNPs) surrounding the natriuretic peptide precursor B (NPPB) gene with plasma BNP levels in 2970 adult Japanese. METHODS AND RESULTS Association analysis between SNPs of the NPPB gene and plasma BNP revealed significant associations of the 8 SNPs surrounding the entire NPPB gene with plasma BNP levels. For instance, as to SNP rs198389 (T-381C), plasma BNP levels among the three genotypic categories, i.e., 2189 homozygous T-allele carriers (BNP 26.4+/-0.6pg/ml), 697 heterozygous carriers (35.0+/-1.1pg/ml), and 52 homozygous C-allele carriers (46.0+/-4.1pg/ml) indicated a co-dominant effect of the minor C-allele on elevating plasma BNP levels (P<0.0001). Linkage disequilibrium (LD) analysis among the 8 SNPs revealed that the region consisted of two, 5' major and 3' minor, LD blocks. Haplotype-based association analysis demonstrated that plasma BNP levels were associated closely with the haplotypes-1 and -2 of the major LD block. CONCLUSION These results suggest that genetic variation at the primary locus NPPB gene, represented by definition of risk haplotypes, may be an important determinant of plasma BNP levels.

Abstract
BACKGROUND Heart-type fatty acid-binding protein (H-FABP) is a small cytosolic protein and released into the circulation when the myocardium is injured. Previous studies have demonstrated that both H-FABP and troponin T (TnT) are detectable in venous blood samples in chronic heart failure (CHF) patients, suggesting the presence of ongoing myocardial damage (OMD). We hypothesized that a cytosolic marker (H-FABP) is more sensitive than a myofibrillar component (TnT) in the detection of OMD in CHF. METHODS AND RESULTS We measured serum H-FABP and TnT levels in 126 consecutive CHF patients at admission, and patients were followed-up with a mean period of 474 +/- 328 days. Cutoff values for H-FABP (4.3 ng/mL) and TnT (0.01 ng/mL) were determined from previous studies. Positive rate of H-FABP was higher than that of TnT in all CHF patients (46% [58/126] versus 26% [33/126], P < .0001), and in severe CHF (New York Heart Association III/IV) patients (69% [34/49] versus 47% [23/49], P = .0121). There were 27 cardiac events during a follow-up period. In patients with cardiac events, H-FABP was more frequently detected than TnT (88% [24/27] versus 44% [12/27], P = .0103). There were 33 patients with positive H-FABP among 93 patients with negative TnT. Those patients had more severe New York Heart Association class, higher levels of brain natriuretic peptide, and higher rates of cardiac events (36% versus 5%, P < .0001) compared with those both H-FABP and TnT were negative. Kaplan-Meier analysis demonstrated that in patients with negative TnT, positive H-FABP group had higher risk for cardiac events than negative H-FABP group (P < .0001). A multivariate analysis with Cox proportional hazard model showed that H-FABP was the only independent predictor of cardiac events (hazard ratio 15.677, P = .0001). The area under the receiver operating characteristic curve was larger for H-FABP than for TnT (0.779 versus 0.581; P = .009), suggesting that H-FABP had greater predictive capacity for cardiac events than TnT. CONCLUSIONS H-FABP was more sensitive to detect OMD and could identify patients at high risk more effectively than TnT.

Abstract
In the lungs of smokers, oxidative stress rises due to increase of free radicals and oxidants, including lipid peroxide (LPO). The functions of alveolar macrophages (AMs) are altered in such an environment, and their survival is prolonged against toxicities of cigarette smoke (CS) by an unknown mechanism. Whereas functions of AMs are potentially regulated by various transcriptional factors, their expressions and roles in smoking individuals have not been elucidated. Therefore, we investigated their expressions using murine model of CS exposure. Eight-week-old male B6C3F1 mice were whole-bodily exposed to CS (2 cigarettes/mouse/day, 5 d/wk) for 6 mo. Development of pulmonary emphysema in 6-mo CS-exposed mice was confirmed by a morphometric analysis. Among the transcriptional factors investigated, only MafB was upregulated in AMs from CS-exposed mice. DNA binding capacity of MafB for Maf recognition element was also increased in AMs from those mice. LPO was increased significantly in the lungs of CS-exposed mice. Because the end product of LPO, 4-hydroxy-2-nonenal, enhanced MafB expression and its transcriptional activity in a cultured macrophage cell line, LPO-related oxidative stress was suggested to be involved in the mechanism of MafB expression in CS-exposed lung. Furthermore, we established a macrophage cell line that can overexpress MafB and thereby clarify the role of MafB. Forced expression of MafB heightened cell viability and attenuated the occurrence of apoptosis in cells treated with CS-extract. These results suggest that enhanced MafB expression by oxidative stress inhibits AM cell death and prolongs their survival in the CS-exposed lung.

Abstract
BACKGROUND AND OBJECTIVE COPD is a multifactorial disease influenced by genetic and environmental factors, and gene-by-environmental interactions. There is considerable variability in the degree of airflow obstruction, moreover only 10-15% of chronic smokers develop COPD. These observations indicate that additional risk factors, possibly genetic, contribute to not only the susceptibility to COPD but also the development and severity of COPD. Recent paradigms highlight the presence and causal role of apoptosis in emphysema. There is a large amount of information on the genes involved in the regulation of apoptosis and one of the most studied is Bcl-2. The aim of this study was to investigate the genetic association of Bcl-2 gene with the level of lung function, that is, the severity, of COPD. METHODS The genetic association of Bcl-2 polymorphisms with lung function was investigated in 261 Japanese patients with COPD using 12 single-nucleotide polymorphisms (SNPs) in Bcl-2. RESULTS Four SNPs showed a significant association between the high and low lung function groups in a dominant trait comparison. Subsequent linkage-disequilibrium mapping and analyses of haplotype structure also showed a significant association between the level of lung function and two haplotypes comprised of the associated SNPs in Bcl-2. CONCLUSIONS Although the linkage between Bcl-2 gene and the susceptibility to COPD remains to be clarified, the findings of the current study indicate that Bcl-2 might be influencing the level of lung function, that is, the development and severity of COPD.

Abstract
BACKGROUND AND OBJECTIVE The molecular mechanisms underlying COPD remain undetermined. The lungs of surfactant protein-D (SP-D) deficient mice show emphysema and an excessive number of foamy macrophages. This study aims to elucidate roles of SP-D and foamy macrophages in smoking-induced mouse emphysema. METHODS Twenty B6C3F1 mice were exposed to cigarette smoke (2 cigarettes/day/mouse for 6 months). The mice were killed, and formalin-fixed, paraffin-embedded lung sections were carried out on seven mice, BAL was carried out on six mice, and seven mice were used to make lung homogenates. In in vitro studies, A549 cells were transduced with the SP-D expression plasmid and treated with cigarette smoke extract to evaluate cell viability. RESULTS Emphysema was induced in the mice by chronic cigarette smoke exposure. Increased expression of matrix metalloproteinase-9 and -12 was observed, and foamy alveolar macrophages accumulated in the smoke-exposed lungs. Immunostaining of BAL cells revealed the major source of matrix metalloproteinase-12 to be foamy alveolar macrophages. Furthermore, SP-D was elevated in emphysema lungs. Expression of transcription factors, Fra-1, junB and C/EBPbeta (which induce SP-D) were significantly elevated in emphysema lungs. The in vitro expression of SP-D gene in A549 cells prolonged cell survival following exposure to cigarette smoke condensate. CONCLUSIONS The accumulation of foamy alveolar macrophages may play a key role in the development of smoking-induced emphysema. Increased SP-D may play a protective role in the development of smoking-induced emphysema, in part by preventing alveolar cell death.

Abstract
BACKGROUND It has been speculated that clarithromycin (CAM), a 14-membered ring macrolide, possesses antitumor effects besides antimicrobial and anti-inflammatory effects. METHOD We evaluated the effects of CAM on the growth and invasiveness of A549 lung adenocarcinoma cells. RESULTS Although CAM did not affect the growth of A549 cells, the Matrigel invasion assay showed that the potential of invasion was diminished by CAM treatment. When analyzed by flow cytometry, CAM suppressed alpha(2)- and beta(1)-integrin expression. Furthermore, thymidine phosphorylase (TP) expression was diminished by CAM treatment in a dose-dependent manner. A specific TP inhibitor also suppressed beta(1)-integrin expression in flow cytometric analysis. CONCLUSIONS These results suggest that CAM may suppress invasive activity of A549 cells in part by diminishing the expression of TP, alpha(2)- and beta(1)-integrin, which may be a downstream signal of the TP pathway, and that CAM could be useful in the treatment of lung adenocarcinoma.

Abstract
BACKGROUND Serum heart-type fatty acid-binding protein (H-FABP) has been widely used as a marker of cardiac myocyte injury. This study was carried out to examine the relationships of H-FABP levels with age, gender, and other physiologic characteristics in a large population of community-dwelling residents. METHODS AND RESULTS Serum H-FABP levels were measured in 2,099 subjects who received an annual health check-up (age 40-87 years). The relationships between H-FABP and blood pressure, laboratory data, electrocardiogram (ECG) findings, and lifestyle factors were cross-sectionally analyzed. Mean H-FABP values were significantly higher in men than in women. Serum H-FABP levels were increased with aging significantly. Both the multivariate regression and multiple logistic regression analyses indicated that serum H-FABP levels were independently affected by age, body mass index, creatinine clearance, and ECG abnormality score. CONCLUSION Serum H-FABP levels were affected by age, gender, obesity, renal function, and ECG abnormality in a large group of volunteers. These effects should be taken into account in determining appropriate reference values for H-FABP. In addition, high serum H-FABP levels may represent latent cardiac injury and have important clinical implications.

Abstract
BACKGROUND Resistin is derived from fat tissue in rodents, and serum levels are elevated in animal models of obesity and insulin resistance. Recent studies have reported that resistin is correlated with markers of inflammation and oxidative stress and is predictive of coronary atherosclerosis in humans. However, clinical significance of serum resistin has not been examined in heart failure. Therefore, the purpose of this study was to examine whether: (1) resistin is correlated with the severity of heart failure; and (2) resistin can predict clinical outcomes of patients with heart failure. METHODS AND RESULTS Serum levels of resistin in 126 patients hospitalized for heart failure and 18 control subjects were measured. The patients were followed up with end-points of cardiac death and re-hospitalization caused by worsening of heart failure. The serum resistin level was higher in patients with heart failure than in control subjects and increased with advancing New York Heart Association functional class. The normal upper limit of the resistin level was determined as the mean +2 standard deviation value of control subjects (14.1 ng/ml). In heart failure patients, the cardiac event rate was higher in patients with a high resistin level than in those with a normal level. Among age, body mass index, serum levels of resistin, brain natriuretic peptide, loop diuretics selected by the univariate Cox regression hazard analysis, age and resistin were significant predictors of future cardiac events by multivariate Cox analysis. CONCLUSION Serum resistin was related to the severity of heart failure and associated with a high risk for adverse cardiac events in patients with heart failure.

Abstract
SUMMARYCholesterol is a major component of the erythrocyte membrane. In the present study, we investigated the effects of cholesterol reduction in host bovine erythrocytes (RBC) on the growth ofBabesia bovis, a major bovine haemoprotozoon. Anin vitrogrowth assay with bovine RBC that had been prepared by pre-treatment with a cholesterol depletion agent (methyl-β-cyclodextrin, MCD) showed that the culture with 5 mmMCD-treated RBC inhibited the growth ofB. bovissignificantly as compared with that with the control RBC. In further experiments, the treatment with 5 mmMCD was proved to suppress both activities of the parasite, erythrocyte invasion and replication within the infected RBC. In contrast, a slight reduction in the membrane cholesterol by 1 mmMCD treatment promoted both their growth and erythrocyte invasion activity. These results indicate that erythrocyte invasion and replication byB. bovisare affected by the amount of cholesterol in the host erythrocyte membrane.

Abstract
BACKGROUND AND PURPOSE The purpose of our retrospective study was to investigate the feasibility, safety, and efficacy of clot removal therapy by aspiration and extraction for patients with acute stroke with embolic internal carotid artery (ICA) occlusion. METHODS Of 814 consecutive patients with acute ischemic stroke admitted to our institution from March 2003 to April 2005, clot removal therapy was performed for 14. Inclusion criteria were patients (1) presenting within 6 hours of onset of cardioembolic stroke, (2) with serious neurologic symptoms defined by a National Institutes of Health Stroke Scale (NIHSS) score of at least 11, (3) without extensive high signal intensity on diffusion-weighted MR images but with decreased ipsilateral hemispheric cerebral blood flow on perfusion-weighted images (perfusion/diffusion mismatch), and (4) with total ICA occlusion on angiograms. We removed clots by aspiration and extraction with a microsnare through either a guiding or balloon guide catheter. Radiographic results, 7-day NIHSS, 3-month modified Rankin Scale, and procedure-related complications were evaluated. RESULTS Of 10 patients treated with the balloon guide catheter to temporarily interrupt proximal flow, 7 obtained complete or partial recanalization. The 4 patients treated with the guiding catheter had no recanalization. Of the 7 patients with recanalization, 6 had favorable 7-day neurologic and 3-month functional outcome; all showed anatomic crossflow via the anterior communicating artery. A procedure-related complication, distal embolization into the ipsilateral anterior cerebral artery, occurred in 1 patient. CONCLUSION Balloon guide catheter-assisted clot removal therapy for embolic ICA occlusion may provide a high recanalization rate and good clinical outcome in patients with anatomic crossflow.

Abstract
RATIONALE Acute exacerbations (AEs) in chronic obstructive pulmonary disease (COPD) are a major cause of morbidity and mortality in COPD. OBJECTIVES The marked heterogeneity in the host defense mechanisms may be attributed to single nucleotide polymorphisms (SNPs) in the inflammatory chemokines that show enhanced expression in the airway of patients with COPD who experience AEs. METHODS We investigated four SNPs of the CCL11, CCL1, and CCL5 genes in relation to the frequency and severity of AEs in retrospective and prospective studies of a cohort of 276 male patients with COPD. MEASUREMENTS AND MAIN RESULTS In the 2-yr retrospective study , one SNP (National Center for Biotechnology Information SNP reference: rs2282691) in the predicted enhancer region of the CCL1 gene, encoding a chemotactic factor for a series of leukocytes, was significantly associated with the frequency of AEs in a dominant model (Fisher's exact test: odds ratio [OR], 2.70; 95% confidence interval [CI], 1.36-5.36; p=0.004; logistic regression: OR, 3.06; 95% CI, 1.46-6.41; p=0.003; and Kruskal-Wallis test: p=0.003). In the 30-mo prospective study, the "A" allele was a significant risk allele for the severity of AEs, with a gene-dosage effect (Kaplan-Meier method with log-rank test: AA vs. TT; log-rank statistic: 7.67, p=0.006; Cox proportional hazards regression method: OR, 5.93; 95% CI, 1.28-27.48; p=0.023). The electromobility shift assay showed that C/EBPbeta, a key transcriptional factor in response to pulmonary infections, binds to the "T" allele, but not to the "A" allele. CONCLUSIONS Variants in the CCL1 gene are associated with susceptibility to AEs through their potential implication in the host defense mechanisms against AEs.

Abstract
BACKGROUND Cystatin C, a novel endogenous marker of glomerular filtration rate, has been reported as more sensitive to detect renal insufficiency than creatinine. The purpose of the present study was to examine the clinical significance of serum cystatin C level in patients with mild to moderate heart failure. METHODS AND RESULTS Serum levels of cystatin C were measured by an enzyme immunoassay in 140 patients with heart failure and 64 control subjects without heart failure. Patients were prospectively followed during a median follow-up period of 480 days, with the end points of cardiac death and progressive heart failure requiring rehospitalization. Serum levels of cystatin C were higher in patients with heart failure than in control subjects (1.14 +/- 0.60 ng/mL versus 0.72 +/- 0.14 ng/mL, P < .001). The Cox multivariate proportional hazard analysis revealed that a change of 1 standard deviation (SD) in cystatin C level was the one of independent predictor for cardiac events (hazard ratio, 1.94; 95% confidence interval, 1.29-6.64; P < .01). The cardiac event rate was markedly higher in patients with elevated cystatin C level (> or =1.0 ng/mL) than in those with normal level (< or =1.0 ng/mL) (38.7% versus 10.3%, P < 0.001). Furthermore in patients with normal creatinine levels (n = 91), the cardiac event rate was similarly higher in patients with elevated cystatin C than in those with normal levels (29.2% versus 7.5%, P = .002). CONCLUSION Elevation of serum cystatin C, a new marker of renal function, provides promising prognostic information for clinical outcome in patients with mild to moderate heart failure.

Abstract
OBJECTIVE Apoptosis may be involved in the pathophysiology of cachexia in patients with chronic obstructive pulmonary disease (COPD). The purpose of this study is to assess the potential role of the Fas-Fas ligand (FasL) system in cachexic patients with COPD. PATIENTS AND METHODS We measured the circulating levels of soluble FasL (sFasL), with a newly developed, highly sensitive enzyme-linked immunosorbent assay system in seventy patients with COPD and forty-seven control subjects. RESULTS The levels of sFasL in the COPD patients were significantly lower than those in the control subjects (46+/-29 vs. 55+/-28 pg/ml; p<0.05), whereas the levels of soluble Fas (sFas) remained unchanged between the two groups. The significant correlation between the levels of sFasL and sFas, observed in the control subjects (r=0.304; p<0.05), was absent in the COPD patients. Cachexic COPD patients with a relatively lower BMI (BMI <20 kg/m(2), n=45) and %fat (%fat <20%, n=34), showed significantly increased levels of sFasL compared to non-cachexic COPD patients with a relatively higher BMI (BMI > or =20 kg/m(2), n=25) and %fat (%fat > or =20%, n=36) (BMI; 51+/-33 vs. 36+/-15 pg/ml; p<0.05. %fat; 55+/-33 vs. 37+/-21 pg/ml; p<0.01), due to the inverse relationships between the body composition measurements and the levels of sFasL observed exclusively in the patients (BMI; r=-0.307; p<0.05. %fat; r=-0.283; p<0.05). CONCLUSION These results may suggest that the Fas-FasL system does not play a significant role in the potential triggers of enhanced apoptosis leading to skeletal muscle wasting and adipose tissue depletion in cachexic patients with COPD.

Abstract
RATIONALE Chronic and systemic inflammation, a potential cause of body weight loss in patients with chronic obstructive pulmonary disease (COPD), may be associated with the proinflammatory properties of secretory phospholipases A2 (sPLA2s), especially the group II subfamily sPLA2s. OBJECTIVES We tested our hypothesis that the individual susceptibility to body weight loss in patients with COPD is attributed to the genetic variances of this sPLA2 gene region. METHODS A total of 12 single nucleotide polymorphisms (SNPs) encompassing the sPLA2 gene region were determined in 276 male patients with COPD. MEASUREMENTS AND MAIN RESULTS We first analyzed our patients whose body mass index (BMI) was at the bottom 100 (BMI, 17.13 +/- 1.29 kg/m2) and at the top 100 (23.83 +/- 1.98) in relation to SNPs. Both the Fisher's exact test (odds ratio, 2.36; 95% confidence interval, 1.34-4.18; p = 0.004) and logistic regression analysis (odds ratio, 2.10; 95% confidence interval, 1.13-3.90; p = 0.019) showed statistical significance between one SNP (National Center for Biotechnology Information SNP reference: rs584367) and the reduction of BMI in the recessive model in patients with COPD. Using all the patients, a significant difference between the values of BMI (log transformed) of the mutant group (CT + TT) and that of the nonmutant group (CC) of this SNP (mean [SE], 1.293 [0.005] vs. 1.317 [0.006]; p = 0.003) was found after adjustment for age, smoking habit, and pulmonary function (analysis of covariance). Importantly, this SNP caused a change in amino acids in sPLA2-IID protein (Gly80Ser). CONCLUSIONS These results suggest that sPLA2-IID may be one of the susceptibility genes that contribute to body weight loss in patients with COPD.

Abstract
BACKGROUND AND OBJECTIVES Heart-type fatty acid binding protein (H-FABP) is released into the circulation from the damaged myocardium of patients with severe chronic heart failure. Chronic heart failure is the most frequent cause of death and disability in the elderly. However, there are no data for the prognostic value of H-FABP in the elderly population. This study investigated whether H-FABP can effectively predict the prognosis in elderly patients (> or = 70 years) with chronic heart failure. METHODS Serum H-FABP levels were measured in 90 chronic heart failure patients > or =70 years old (mean age 77 +/- 4 years, range 70-92 years), and patients were followed-up for 421 +/- 326 days. RESULTS There were 35 cardiac events (38.9%) including cardiac deaths and readmissions for worsening chronic heart failure. Multivariate analysis with the Cox proportional hazard model showed that H-FABP was the only independent predictor of cardiac events (chi2 = 6.640, p = 0.0100). Kaplan-Meier analysis revealed that H-FABP effectively risk stratified elderly patients with chronic heart failure for cardiac events. CONCLUSIONS These findings suggest that H-FABP is a reliable marker for prognosis in elderly patients with chronic heart failure.

Abstract
Although it has been reported that chronic obstructive pulmonary disease (COPD) is frequently associated with systemic immune disturbances, negative impact of these disturbances on the increased prevalence of acute respiratory tract infections (aRTIs) has remained unclear. We evaluated circulating levels of interferon-gamma (IFN-gamma), soluble interleukin-2 receptor (sIL-2R), neopterin, and soluble intercellular adhesion molecule-1 (sICAM-1) in 35 clinically stable patients with COPD and in 22 age-matched healthy controls, since these molecules are considered to reflect the in vivo status of systemic cell-mediated immunity (CMI). We found that circulating levels of sIL-2R (1.52+/-1.25 vs. 0.97+/-0.48 ng/ml; P<0.05), neopterin (7.23+/-4.24 vs. 4.95+/-1.52 nmol/l; P<0.05), and sICAM-1 (665+/-302 vs. 328+/-164 ng/ml; P<0.0001), but not IFN-gamma (7.55+/-4.72 vs. 6.65+/-1.13 pg/ml; P=NS) were significantly higher in patients with COPD than in the controls. Importantly, follow-up study for 12 months demonstrated that patients in subgroup with relatively higher circulating levels of sIL-2R (2.20+/-1.44 ng/ml, n=18) had significantly higher risk of developing aRTIs (P=0.0204) than those in subgroup with relatively lower circulating levels of sIL-2R (0.80+/-0.23 ng/ml, n=17). These results may suggest that impaired systemic CMI observed in COPD patients is associated with the increased susceptibility to aRTIs in these patients.

Abstract
BACKGROUND The aim of the present study was to prospectively study whether a combination of markers for myocardial cell injury and left ventricular overload at admission can reliably risk stratify patients hospitalized for chronic heart failure (CHF). METHODS AND RESULTS Serum concentrations of heart-type fatty acid binding protein (H-FABP) and plasma concentrations of brain natriuretic peptide (BNP) were measured at admission in 186 consecutive patients hospitalized for CHF. During a mean follow-up period of 534+/-350 days, there were 44 cardiac events, including 16 cardiac deaths and 28 readmissions for worsening heart failure. Normal upper limits for H-FABP and BNP values were determined from the receiver operating characteristic curves (4.3 ng/ml for H-FABP and 200 pg/ml for BNP). A stepwise Cox regression analysis demonstrated that high H-FABP (hazard ratio 5.416, p = 0.0002) and high BNP (hazard ratio 2.411, p = 0.0463) were independent predictors of cardiac events. High concentrations of both H-FABP and BNP at admission were associated with the highest incidence of cardiac mortality and cardiac events. Kaplan-Meier analysis also showed that the combination of H-FABP and BNP concentrations could reliably stratify patients for cardiac events. CONCLUSION Combined measurement of H-FABP and BNP concentrations at admission may be a highly reliable evaluation for risk stratifying patients hospitalized for CHF.

Abstract
PURPOSE Pulmonary microvascular endothelial injury may be involved in the pathogenesis of pulmonary fibrosis (PF). The aim of this study was to evaluate the pulmonary vascular status in patients with PF by lung scintigraphic assessment of 123I-metaiodobenzylguanidine (123I-MIBG), which reflects latent endothelial cell lesions. METHODS We assessed lung 123I-MIBG kinetics and clinical indices in 23 PF patients and 16 controls. Mean uptake ratios of lung to mediastinum (L/M) were calculated in anterior planar images at 30 (early image) and 270 (delayed image) min after intravenous injection of 123I-MIBG. The pulmonary mean washout rate (WR) of 123I-MIBG was also calculated. RESULTS The L/M ratio in early images, but not in delayed images, was significantly lower in the PF patients than in the controls (L/M(early) 1.41+/-0.14 vs 1.53+/-0.10, p<0.01; L/M(delayed) 1.28+/-0.10 vs 1.33+/-0.07, p=NS). WR was significantly reduced in the PF patients compared with the controls (28.6%+/-3.1% vs 34.2%+/-5.1%, p<0.001). In the study subjects (PF patients plus controls) there were significant relationships between lung WR of (123)I-MIBG and other diagnostic parameters for the severity of PF, such as vital capacity (r=0.625, p<0.0001), total lung capacity (r=0.691, p<0.0001), carbon monoxide diffusing capacity (r=0.622, p<0.0001), serum angiotensin-converting enzyme activity (r=0.422, p<0.01), carbohydrate antigen KL-6 levels (r=-0.495, p<0.01) and surfactant protein-D levels (r=-0.461, p<0.01). When control subjects were excluded, similar significant correlations were observed between WR and %TLC (r=0.508, p<0.05), DL(CO) (r=0.593, p<0.01) and serum ACE activity (r=0.515, p<0.05) in the PF patients. CONCLUSION These results suggest that endothelial cell injury plays a significant role in the pathogenesis of PF, and that lung WR of 123I-MIBG, which is a specific marker of endothelial damage, can serve as a novel diagnostic tool to evaluate the functional severity of PF.

Abstract
UNLABELLED Scintigraphic evaluation of (123)I-metaiodobenzylguanidine ((123)I-MIBG) in the lungs is considered to recognize endothelial cell lesions. The aim of this study was to clarify the involvement of the pulmonary microvascular injury in the pathogenesis of chronic obstructive pulmonary disease (COPD). METHODS We investigated lung (123)I-MIBG kinetics and clinical indices in 25 COPD patients and 12 control subjects. Mean uptake ratios of lung to mediastinum (L/M) were calculated in anterior planer images at 30 min (early image) and 270 min (delayed image) after intravenous injection of (123)I-MIBG. Pulmonary mean washout rate (WR) of the (123)I-MIBG was also calculated. RESULTS The L/M ratios in both early and delayed images of COPD patients, as well as its WR, were significantly lower than those of the control subjects (L/M early: 1.26 +/- 0.18 vs. 1.54 +/- 0.11, P < 0.0001; L/M delayed: 1.20 +/- 0.12 vs. 1.33 +/- 0.09, P < 0.001; WR: 27.4% +/- 5.3% vs. 34.2% +/- 5.7%, P < 0.01). There were significant relationships between lung WR of the (123)I-MIBG and other diagnostic tests for the severity of COPD, such as forced expiratory volume in 1 s (% FEV(1.0): r = 0.386, P < 0.05), carbon monoxide diffusing capacity/alveolar volume (DL(CO)/V(A): r = 0.449, P < 0.01), arterial blood oxygen pressure (PaO(2): r = 0.474, P < 0.01), alveolar-arterial oxygen tension gradient [A-a]DO(2) (r = -0.446, P < 0.01), and percentage of low-attenuation area (r = -0.458, P < 0.01) in the study population. CONCLUSION Because lung WR of the (123)I-MIBG is considered to be independent of an alteration of the pulmonary vascular surface area, these results suggest that the microvascular endothelial cell injury plays a significant role in the pathogenesis of COPD.

Abstract
Thymidine phosphorylase (TP) is expressed at higher levels in a variety of human cancers than in adjacent normal tissue. It is reported that the higher expression is associated with an increase of intratumoral microvessel density and a poor prognosis. We investigated the role of TP in human non small cell lung cancers (NSCLCs). The concentrations of TP in the tumors and the adjacent normal tissue from surgically resected specimens of 54 cases of NSCLCs were measured by using an enzyme-linked immunosorbent assay. Tumor specimens were also examined immunohistochemically. TP concentrations in the tumors were 169 +/- 18 units/mg protein (mean +/- SD), whereas those in normal tissue were 43 +/- 4 units/mg protein (mean +/- SD), consistent with TP staining patterns. There was no correlation between TP expression and microvessel density. Among clinicopathologic factors examined, the concentrations of TP but not TP immunoreactivity correlated with tumor differentiation in lung adenocarcinoma. Although a specific TP inhibitor (TPI) and overexpression of TP did not affect the growth of A549 lung adenocarcinoma cells, Matrigel invasion assay showed that A549 transfected with TP had higher invasive potential than mock transfectant, and such enhanced invasive activity was markedly diminished by treatment with TPI. Furthermore, administration of TPI suppressed lung metastasis of TP-overexpressing A549 cells in nude mice. These results demonstrate that TP may play an important role in tumor differentiation, invasiveness and metastasis in lung adenocarcinoma, and suggest that TP could be a novel target for treatment of TP-overexpressing lung adenocarcinoma.

Abstract
Surfactant protein B (SP-B) is known to promote surfactant phospholipid film formation and reduce surface tension. Native SP-B is a homodimer in which subunit association is stabilized via covalent linkage through cysteine 48. We hypothesized that loss of the intersubunit bridge would alter SP-B function and lead to increased inflammation in response to challenge by hyperoxia or endotoxin. Transgenic mice in which SP-B cysteine 48 was mutated to serine were generated and crossed into the SP-B(-/-) background. Wild-type mice and transgenic mice carrying a single copy (SP-Bmon(+)) or two copies (SP-Bmon(++)) of the transgene were exposed to 95% O2 for 3 days or intratracheally injected with 10 microg of endotoxin. Interleukin-1beta, major intrinsic protein 2, and interleukin-6 in lung homogenates after 3 days of hyperoxia were significantly higher (P < 0.001) in SP-Bmon(+) mice than SP-Bmon(++) or wild-type mice. At 16 h after endotoxin injection, cytokines in lung tissues were higher in SP-Bmon(+) mice compared with wild-type mice (P < 0.05). Consistent with prolonged recovery in SP-Bmon(+) mice, the percentage of apoptotic cells in alveolar lavage was significantly lower in SP-Bmon(+) mice than in SP-Bmon(++) and wild-type mice. Overall, increased inflammation in SP-Bmon(+) mice was corrected to a large extent by increased gene dosage, indicating that formation of the intersubunit disulfide bridge is not critical for SP-B function.

Abstract
Cachexic patients with chronic obstructive pulmonary disease (COPD) show abnormalities of the autonomic nervous system (ANS), neuroendocrine function, and energy expenditure. Leptin has been implicated in the regulation of ANS, neuroendocine function, and thermogenesis in humans. We assessed the physiologic significance of the circadian rhythm of circulating leptin using power spectrum analysis of heart rate variability (HRV) in nine cachexic male patients with COPD, eight noncachexic patients with COPD, and seven healthy control subjects. A diurnal pattern of 24-h leptin levels was present in both the control subjects (analysis of variance [ANOVA]; F = 7.80, p < 0.0001) and noncachexic COPD patients (F = 9.29, p < 0.0001), but was strikingly absent in the cachexic COPD patients (F = 2.09, p = NS). Analysis of HRV demonstrated that the diurnal rhythm of 24-h very low frequency (VLF; 0.003 to 0.04 Hz) showed significantly identical fluctuations with those of 24-h leptin levels, in all of the three groups (r = 0.388, p < 0.0001). Because VLF has been considered to reflect neuroendocrine and thermoregulatory influences, these data may suggest that the loss of circadian rhythm of circulating leptin has clinical importance in the pathophysiologic features in cachexic patients with COPD.

Abstract
Fas- and tumour necrosis factor (TNF) receptor-mediated apoptosis are known to be two principal apoptotic mechanisms in humans. Although there are several distinctions between these two systems, in vitro studies have demonstrated similar hypoxic activation and a functional relationship. Since patients with chronic obstructive pulmonary disease (COPD) show chronic hypoxaemia and the activation of the TNF-alpha system, we investigated whether these pathophysiological changes influence the Fas-Fas ligand system. We measured the circulating soluble Fas ligand (sFas-L) level, an inducer of apoptosis, and the soluble Fas receptor (sFas) level, an inhibitor of apoptosis, in 34 COPD patients and 35 age-matched healthy controls. In addition, we investigated the relationships between the levels of sFas-L or sFas and clinical variables including the TNF-alpha system; circulating TNF-alpha and soluble TNF-receptor (sTNF-Rs: sTNF-R55 and R75) levels, in the COPD patients. Although circulating TNF-alpha, sTNF-R55 and R75 levels were significantly higher in the COPD patients than in the healthy controls, serum level of sFas-L (Fisher's exact probability test; P = 0.26) and plasma level of sFas [COPD patients vs. controls; mean (SD); 3.74 (0.63) vs. 3.67 (0.48) ng/ml; P = 0.89) were not increased in the COPD patients. There was no significant correlation between the levels of sFas-L or sFas and clinical variables in COPD patients. These results suggest that the Fas-Fas ligand system does not independently play an important role in the pathophysiology of patients with COPD.

Abstract
Although circulating tumor necrosis factor (TNF)-alpha levels have been found to be increased in weight-losing patients with chronic obstructive pulmonary disease (COPD), the main causes for this phenomenon remain to be elucidated. Since hypoxia itself can enhance the production of the TNF-alpha in vitro, we studied the relationship between hypoxemia and activities of the TNF-alpha system, including circulating TNF-alpha and soluble TNF-receptors (sTNF-R; sTNF-R55 and -R75) levels, in 27 COPD patients and 15 age-matched healthy controls. The COPD patients showed a significant weight loss (body mass index = 18.1 +/- 2.8 versus 22.8 +/- 2.2 [mean +/- SD] kg/m(2); p < 0.0001. % fat = 16.3 +/- 5.9 versus 24.3 +/- 4.9 %; p < 0.001), and hypoxemia (Pa(O2 )= 62.2 +/- 9.5 versus 88.6 +/- 5.9 mm Hg; p < 0.0001) as compared with the healthy controls. Serum TNF-alpha (6.15 +/- 1.08 versus 5.41 +/- 1.60 pg/ml; p < 0.05) and plasma sTNF-R55 (1.15 +/- 0.49 versus 0.67 +/- 0.13 ng/ml; p < 0.0001) and sTNF-R75 (3.54 +/- 1.16 versus 2.25 +/- 0.43; p < 0.0001) levels were significantly higher in the COPD patients than in the healthy controls. There were inverse correlations between Pa(O(2)) and circulating TNF-alpha and sTNF-R levels in patients with COPD (TNF-alpha; r = -0.426, p = 0.0297; sTNF-R55: r = -0.587, p = 0.0027; sTNF-R75: r = -0.573, p = 0.0035). In addition, we found inverse correlations between sTNF-R levels and % fat in COPD patients (sTNF-R55: r = -0.442, p = 0.0272; sTNF-R75: r = -0. 484, p = 0.0155). TNF-alpha levels correlated well with sTNF-R levels (sTNF-R55: r = 0.488, p = 0.0127; sTNF-R75: r = 0.609, p = 0. 0019). These relationships were not observed in the healthy controls. These data suggest that systemic hypoxemia noted in patients with COPD is associated with activation of the TNF-alpha system in vivo, which may be a factor contributing to the weight loss in patients with the disease.

Abstract
We experienced a rare case of lung adenocarcinoma associated with lymphocytic interstitial pneumonitis caused by primary Sjögren's syndrome. A 78-year-old woman was referred to our hospital because of progressive sicca syndrome and nodular opacities in the right lower lobe on chest radiograph. This patient was diagnosed as primary Sjögren's syndrome by a labial gland biopsy and classical clinical features including xerophthalmia, xerostomia and immunoserological findings. Pathological findings including immunohistochemical studies in a surgically resected lung revealed adenocarcinoma in lymphocytic interstitial pneumonitis associated with primary Sjögren's syndrome. There was no evidence of malignant lymphoma in the lymph nodes or resected lung tissue. Pulmonary involvement of Sjögren's syndrome is now regarded both clinically and histopathologically as a wide spectrum of lymphoproliferative disorders ranging from benign to malignant. However, lung cancer associated with primary Sjögren's syndrome, as in our case, has apparently not been reported previously.

Abstract
Unexplained weight loss is common in patients with chronic obstructive pulmonary disease (COPD). Since leptin, an obesity gene product, is known to play important roles in the control of body weight and energy expenditure, we investigated serum leptin levels, along with circulating tumor necrosis factor-alpha (TNF-alpha) and soluble TNF receptor (sTNF-R55 and -R75) levels, in 31 patients with COPD and 15 age-matched healthy controls. The body mass index (BMI) and percent body fat (%fat) were significantly lower in the COPD patients than in the healthy controls (BMI = 18.1 +/- 2.7 kg/m2 versus 22.8 +/- 2.2 kg/m2 [mean +/- SD]; p < 0.0001; %fat = 16.9 +/- 5.8% versus 24.3 +/- 4.9%; p < 0.001). Serum leptin levels were significantly lower in the COPD patients than in the healthy controls (1.14 +/- 1.17 ng/ml versus 2.47 +/- 2.01 ng/ml; p < 0.05). In contrast, serum TNF-alpha levels (6.59 +/- 1.92 pg/ml versus 5.41 +/- 1.60 pg/ml; p < 0.05), plasma sTNF-R55 (1.16 +/- 0.47 ng/ml versus 0.67 +/- 0.13 ng/ml; p < 0.0001) and sTNF-R75 (3.65 +/- 1.29 ng/ml versus 2.25 +/- 0.43 ng/ml; p < 0.0001) levels were significantly higher in the COPD patients than in the healthy controls. Importantly, circulating leptin levels (log transformed) did correlate well with BMI and %fat, but not with TNF-alpha or with sTNF-R levels in the COPD patients. These data suggest that circulating leptin is independent of the TNF-alpha system and is regulated physiologically even in the presence of cachexia in patients with COPD.

Abstract
The apolipoprotein (a) [apo(a)] gene encodes a protein component of lipoprotein (a) [Lp(a)] whose plasma levels vary among individuals. To study the implications of Lp(a), we examined plasma Lp(a) levels and molecular weights of apo(a) in patients with cerebrovascular disease (CVD) or diabetes mellitus (DN). Mean Lp(a) concentrations were higher in the CVD cases with atherothrombotic brain infarction than in those with brain hemorrhage and lacunar infarction. Lp(a) levels were lower in the DM cases on diet therapy alone than in those treated with insulin or oral hypoglycemic agents. These results suggest that Lp(a) is thrombogenic and atherogenic, and that insulin may modulate Lp(a) levels. We subclassified the apo(a) gene into four types (A-D) by polymorphisms in the 5'-flanking region. We also measured plasma Lp(a) concentrations and examined expression of the gene by an in vitro assay. Homozygotes of type C had higher Lp(a) levels than those of type D, and the relative expression of type C was higher than that of type D in vitro. Lp(a) levels, however, varied even within the same 5'-allele having similar apo(a) isoforms. Thus, Lp(a) concentrations are genetically determined and may be modified by some hormones and cytokines. When we examined transcript levels for apo(a) by RT-PCR in various normal tissues, apo(a) was strongly expressed in liver while not in thyroid or leukocytes. Small amounts of apo(a) transcript were observed in all other organs and tissues. Apo(a) in these tissues may also play a role in inframmation, tissue remodeling, cell migration, and other physiological functions.

Abstract
Various Kringle 4 (K4) sequences were identified in human genomic clones and genomic DNAs amplified by PCR. These K4s were homologous to those found in the apo(a) gene and thus termed apo(a)-related genes (ARGs). The same sequences were obtained when human peripheral leukocytes were analyzed by reverse transcription-PCR in order to study the expression mode of the ARGs. It was of note that multiple transcripts with three optional exons for an ARG (ARGII) were detected in leukocytes, indicating that they were generated by alternative splicing. All these transcripts possessed the first half of the second K4 sequence, which had been reported to be skipped. The variant products of ARGII are expected to contain an additional region of either 44, 66, or 100 unique amino acids at the C-terminus of a single K4 unit. When normal human tissues and cultured tumor cells were analyzed, the multiple ARGII transcripts were detected at varying levels. The presence of the cellular state-specific alternative splicing machinery may provide not only redundancy but also diversity in the structure/function of ARGII.

Abstract
An 84-year-old man was admitted to Yonezawa City Hospital with fever, cough, hemoptysis and progressive dyspnea. He had complained of wheezing asthmatoid and exertional dyspnea for the previous 10 years, regardless of the season. On admission, chest radiographs revealed a diffuse ground-glass shadow, fibrotic change, and volume reduction. Arterial blood gas analysis showed extreme hypoxemia. A computed tomographic (CT) scan of the chest showed not only faint ground-glass opacities and dense patches in the whole lung field, but also central bronchiectasis. Laboratory tests revealed that both total serum levels of IgE and specific IgE for Candida albicans were elevated. In the bronchoalveolar lavage fluid, lymphocyte, neutrophil and eosinophil percentages were high, and the CD4/CD8 ratio was low. We diagnosed the fibrotic stage of allergic bronchopulmonary candidiasis. During treatment with hydrocortisone and fluconazole, eosinophilia in the peripheral blood was observed, and serum candida antigen was positive. In addition, high serum levels of soluble interleukin 2 receptors were observed in this patient.
