Abstract
Contrast media exposure is associated with contrast-induced nephropathy (CIN) following percutaneous coronary intervention (PCI) of chronic total occlusion (CTO). Aim of this study is to assess the utility of minimum contrast media volume (CMV ≤ 50 mL) during CTO-PCI for CIN prevention in patients with chronic kidney disease (CKD). We extracted data from the Japanese CTO-PCI expert registry; 2863 patients with CKD who underwent CTO-PCI performed from 2014 to 2020 were divided into two groups: minimum CMV (n = 191) and non-minimum CMV groups (n = 2672). CIN was defined as an increased serum creatinine level of ≥ 25% and/or ≥ 0.5 mg/dL compared with baseline levels within 72 h of the procedure. In the minimum CMV group, the CIN incidence was lower than that in the non-minimum CMV group (1.0% vs. 4.1%; p = 0.03). Patient success rate was higher and complication rate was lower in the minimum CMV group than in the non-minimum CMV group (96.8% vs. 90.3%; p = 0.02 and 3.1% vs. 7.1%; p = 0.03). In the minimum CMV group, the primary retrograde approach was more frequent in the case of J-CTO = 1,2 and 3-5 groups compared to that in non-minimum CMV-PCI group (J-CTO = 0; 11% vs. 17.7%, p = 0.06; J-CTO = 1; 22% vs. 35.8%, p = 0.01; J-CTO = 2; 32.4% vs. 46.5%, p = 0.01; and J-CTO = 3-5; 44.7% vs. 80.0%, p = 0.02). Minimum CMV-PCI for CTO in CKD patients could reduce the incidence of CIN. The primary retrograde approach was observed to a greater extent in the minimum CMV group, especially in cases of difficult CTO.

Abstract
The Task Force on Rotational Atherectomy of the Japanese Association of Cardiovascular Intervention and Therapeutics (CVIT) proposed the expert consensus document to summarize the techniques and evidences regarding rotational atherectomy (RA) in 2020. Because the revascularization strategy to severely calcified lesions is the hottest topic in contemporary percutaneous coronary intervention (PCI), many evidences related to RA have been published since 2020. Latest advancements have been incorporated in this updated expert consensus document.

Abstract
Aim:
This study investigated whether the small dense low-density lipoprotein cholesterol (sd-LDL-c) level is associated with the rapid progression (RP) of non-culprit coronary artery lesions and cardiovascular events (CE) after acute coronary syndrome (ACS).
Methods:
In 142 consecutive patients with ACS who underwent primary percutaneous coronary intervention for the culprit lesion, the sd-LDL-c level was measured using a direct homogeneous assay on admission for ACS and at the 10-month follow-up coronary angiography. RP was defined as a progression of any pre-existing coronary stenosis and/or stenosis development in the initially normal coronary artery. CEs were defined as cardiac death, myocardial infarction, stroke, or coronary revascularization.
Results:
Patients were divided into two groups based on the presence (
n
=29) or absence (
n
=113) of RP after 10 months. The LDL-c and sd-LDL-c levels at baseline were equivalent in both the groups. However, the sd-LDL-c, triglyceride, remnant lipoprotein cholesterol (RL-c), and apoC3 levels at follow-up were significantly higher in the RP group than in the non-RP group. The optimal threshold values of sd-LDL-c, triglyceride, RL-c, and apoC3 for predicting RP according to receiver operating characteristics analysis were 20.9, 113, 5.5, and 9.7 mg/dL, respectively. Only the sd-LDL-c level (≥ 20.9 mg/dL) was significantly associated with incident CEs at 31±17 months (log-rank: 4.123,
p
=0.043).
Conclusions:
The sd-LDL-c level on treatment was significantly associated with RP of non-culprit lesions, resulting in CEs in ACS patients. On-treatment sd-LDL-c is a residual risk and aggressive reduction of sd-LDL-c might be needed to prevent CEs.

Abstract
Rotational atherectomy (RA) has been widely used for percutaneous coronary intervention (PCI) to severely calcified lesions. As compared to other countries, RA in Japan has uniquely developed with the aid of greater usage of intravascular imaging devices such as intravascular ultrasound (IVUS) or optical coherence tomography (OCT). IVUS has been used to understand the guidewire bias and to decide appropriate burr sizes during RA, whereas OCT can also provide the thickness of calcification. Owing to such abundant experiences, Japanese RA operators modified RA techniques and reported unique evidences regarding RA. The Task Force on Rotational Atherectomy of the J apanese Association of Cardiovascular Intervention and Therapeutics (CVIT) has now proposed the expert consensus document to summarize the contemporary techniques and evidences regarding RA.

Abstract
BACKGROUND This prospective randomized multicenter open-label trial evaluated whether sodium-glucose cotransporter-2 inhibitor (SGLT2-i) improves left ventricular (LV) pump function and suppresses elevation of LV filling pressure (LVFP) and right ventricular systolic pressure (RVSP) during exercise in type 2 diabetes mellitus (T2DM) patients.Methods and Results:Based on HbA1c and LV ejection fraction, 78 patients with poorly controlled T2DM were randomly assigned to D-group (dapagliflozin 5 mg/day add-on) or C-group (conventional therapy add-on). Physical examination, home and office blood pressure examination, blood tests, and echocardiography at rest and during ergometer exercise were performed at baseline and at 1.5 and 6 months after treatment. The primary endpoint was defined as the change in RVSP (mmHg) between baseline and 6-month follow up. The secondary endpoints were changes in LVFP (ratio), stroke volume index (SVi; mL/m2), and cardiac index (CI; L/min/m2). Both RVSP and LVFP during exercise significantly decreased from baseline to 6 months after starting treatment in the D-group (P<0.001). No changes to either parameter was observed in the C-group. The SVi and CI did not improve in either group. Both home and office blood pressure significantly decreased in the D-group. Decreases in HbA1c were somewhat greater in the C-group. CONCLUSIONS Dapagliflozin significantly improved RVSP and LVFP during exercise in patients with T2DM and cardiovascular risk, which may contribute to favorable effects on heart failure.

Abstract
Oxidized LDL (oxLDL) is a known risk factor for atherogenesis. This study aimed to reveal structural features of oxLDL present in human circulation related to atherosclerosis. When LDL was fractionated on an anion-exchange column, in vivo-oxLDL, detected by the anti-oxidized PC (oxPC) mAb, was recovered in flow-through and electronegative LDL [LDL(-)] fractions. The amount of the electronegative in vivo-oxLDL, namely oxLDL in the LDL(-) fraction, present in patients with acute MI was 3-fold higher than that observed in healthy subjects. Surprisingly, the LDL(-) fraction contained apoA1 in addition to apoB, and HDL-sized particles were observed with transmission electron microscopy. In LDL(-) fractions, acrolein adducts were identified at all lysine residues in apoA1, with only a small number of acrolein-modified residues identified in apoB. The amount of oxPC adducts of apoB was higher in the LDL(-) than in the L1 fraction, as determined using Western blotting. The electronegative in vivo-oxLDL was immunologically purified from the LDL(-) fraction with an anti-oxPC mAb. The majority of PC species were not oxidized, whereas oxPC and lysoPC did not accumulate. Here, we propose that there are two types of in vivo-oxLDL in human circulating plasma and the electronegative in vivo-oxLDL accompanies oxidized HDL.

Abstract
OBJECTIVES We aimed to investigate strategies for reattempted percutaneous coronary interventions (PCIs) for chronic total occlusions (CTOs) by highly skilled operators after a failed attempt. BACKGROUND Development of complex techniques and algorithms has been standardized for CTO-PCI. However, there is no appropriate strategy for CTO-PCI after a failed procedure. METHOD From 2014 to 2016, the Japanese CTO-PCI Expert Registry included 4,053 consecutive CTO-PCIs (mean age: 66.8 ± 10.9 years; male: 85.6%; Japanese CTO [J-CTO] score: 1.92 ± 1.15). Initial outcomes and strategies for reattempted CTO-PCIs were evaluated and compared with first-attempt CTO-PCIs. RESULTS Reattempt CTO-PCIs were performed in 820 (20.2%) lesions. The mean J-CTO score of reattempt CTO-PCIs was higher than that of first-attempt CTO-PCIs (2.86 ± 1.03 vs. 1.68 ± 1.05, p < .001). The technical success rate of reattempt CTO-PCIs was lower than that of first-attempt CTO-PCIs (86.7% vs. 90.8%, p < .001). Regarding successful CTO-PCIs, the strategies comprised antegrade alone (reattempt: 36.1%, first attempt: 63.8%), bidirectional approach (reattempt: 54.4%, first attempt: 30.3%), and antegrade approach following a failed bidirectional approach (reattempt: 9.4%, first attempt: 5.4%). Parallel wire technique, intravascular ultrasound guide crossing, and bidirectional approach technique were frequently performed in reattempt CTO-PCIs. Reattempt CTO-PCIs showed higher rates of myocardial infarction (2.1% vs. 0.9%, p < .001) and coronary perforation (6.9% vs. 4.2%, p = .002) than first-attempt CTO-PCIs. CONCLUSIONS The technical success rate of reattempt CTO-PCIs is lower than that of first-attempt CTO-PCIs. However, using more complex strategies, the success rate of reattempt CTO-PCI can be improved by highly skilled operators.

Abstract
AIM The study objective was to investigate whether small dense low-density lipoprotein cholesterol (sdLDL-C) is superior to low-density lipoprotein cholesterol (LDL-C) and other biomarkers to predict future cardiovascular events (CE) in secondary prevention. METHODS sdLDL-C measured by a homogeneous assay, remnant lipoprotein cholesterol, LDL particle diameter and other biomarkers were compared in 345 men aged ≥65 years with stable coronary artery disease. Baseline LDL-C was 100.5 ± 30.1 mg/dL. CE including cardiovascular death, onset of acute coronary syndrome, need for arterial revascularization, hospitalization for heart failure, surgery procedure for cardiovascular disease and hospitalization for stroke were monitored for 5 years. RESULTS CE occurred in 96 patients during the study period. LDL-C, sdLDL-C non-high-density lipoprotein cholesterol, apolipoprotein B, remnant lipoprotein cholesterol, glucose, glycated hemoglobin and brain natriuretic peptide were significantly higher; LDL particle diameter and apolipoprotein A-1 were significantly lower in patients with than in those without CE. Age-adjusted Cox regression analysis showed that sdLDL-C per 10 mg/dL, but not LDL-C, was significantly associated with CE (HR 1.206, 95% CI 1.006-1.446). A significant association of sdLDL-C and incident CE was observed in statin users (HR 1.252, 95% CI 1.017-1.540), diabetes patients (HR 1.219, 95% CI 1.018-1.460), patients without diabetes (HR 1.257, 95% CI 1.019-1.551) and patients with hypertriglyceridemia (HR 1. 376, 95% CI 1.070-1.770). CONCLUSIONS sdLDL-C was the most effective predictor of residual risk of future CE in stable coronary artery disease patients using statins and in high-risk coronary artery disease patients with diabetes or hypertriglyceridemia.

Abstract
Our data shows the regional coronary artery calcium scores (lesion CAC) on multidetector computed tomography (MDCT) and the cross-section imaging on MDCT angiography (CTA) in the target lesion of the patients with stable angina pectoris who were scheduled for percutaneous coronary intervention (PCI). CAC and CTA data were measured using a 128-slice scanner (Somatom Definition AS+; Siemens Medical Solutions, Forchheim, Germany) before PCI. CAC was measured in a non-contrast-enhanced scan and was quantified using the Calcium Score module of SYNAPSE VINCENT software (Fujifilm Co. Tokyo, Japan) and expressed in Agatston units. CTA were then continued with a contrast-enhanced ECG gating to measure the severity of the calcified plaque condition. We present that both CAC and CTA data are used as a benchmark to consider the addition of rotational atherectomy during PCI to severely calcified plaque lesions.

Abstract
We report on a 74-year-old man with chronic total occlusion (CTO) of the right coronary artery treated with percutaneous coronary intervention using the bidirectional kissing-balloon technique. When an antegrade approach fails, a retrograde approach to recanalize a CTO is reasonable. However, when the exit of the CTO is bifurcated and a protection wire does not advance antegrade into the side branch after wire externalization, loss of blood flow after ballooning or stenting may result. We report on the usefulness of the bidirectional kissing-balloon technique for a retrograde approach to chronically totally occluded coronary arterial bifurcation lesions.

Abstract
AIM The aim of the present study was to investigate how small dense low-density lipoprotein cholesterol (sdLDL-C) compared with LDL-C affect the long-term prognosis in patients with stable coronary artery disease (CAD). METHODS sdLDL-C measured by heparin magnesium precipitation and LDL particle size measured by non-denatured gradient-gel electrophoresis were compared in 190 consecutive CAD patients who underwent coronary arteriography between 2003 and 2004 who did or did not develop cardiovascular events during a seven-year follow-up period. Cardiovascular events were death caused by cardiovascular diseases(CVDs), onset of acute coronary syndrome, need for coronary and peripheral arterial revascularization, hospitalization for heart failure, surgical procedure for any CVDs, and/or hospitalization for stroke. RESULTS First-time cardiovascular events were observed in 72 patients. Those who experienced cardiovascular events were older and had higher prevalence rates of hypertension and diabetes; significantly higher Gensini coronary atherosclerotic scores; significantly higher levels of sdLDL-C, sdLDL-C/LDL-C, and LDL-C/high-density lipoprotein cholesterol (HDL-C) ratios; and greater glycated hemoglobin(Hb)A1c and brain natriuretic peptide (BNP) levels. They also had significantly smaller LDL particle sizes, HDL-C, apolipoprotein A-1, and estimated glomerular filtration rate (GFR) compared with patients without cardiovascular events. Conversely, LDL-C, non-HDL-C, apolipoprotein B, remnantlike particle cholesterol, and high-sensitivity C-reactive protein (hs-CRP) levels were similar between the two groups. A Kaplan-Meyer event-free survival curve demonstrated that patients with sdLDL-C≥35 mg/dL (median level) had significantly poorer prognosis compared with those with lower sdLDL-C levels, while patients with LDL-C ≥100 mg/dL had a non-significantly lower survival rate. CONCLUSION These results confirm that sdLDL-C is a very promising biomarker to predict future cardiovascular events in the secondary prevention of stable CAD.

Abstract
BACKGROUND Left atrial (LA) remodeling is a factor in atrial fibrillation (AF) recurrence after pulmonary vein catheter ablation (CA), but right atrium (RA) remodeling has not been investigated for possible associations to AF recurrence. METHODS AND RESULTS Using 64-slice multidetector computed tomography, RA and LA volumes were measured 3-dimensionally before CA in 65 patients with initially proven idiopathic paroxysmal AF (mean age, 60±10 years, 81.5% men). The CA procedure was guided by CARTO Merge atrial electroanatomic mapping. Sixteen patients (24.6%) had AF recurrence within the 6-month period after the CA. The recurrence was associated with a large RA volume [odds ratio, 1.04; 95% confidence interval (CI), 1.02 to 1.07, P<0.0001], a large LA volume with 1.04 [95% CI, 1.01 to 1.06, P=0.002], and low LA mean voltage with 1.03 [95% CI, 1.01 to 1.05, P=0.002]. After adjustment for potential confounding variables, RA and LA volumes remained predictive of AF recurrence. Large atrial volumes (mL) (RA ≥87 or LA ≥99) predicted AF recurrence (sensitivity of RA volume: 81.3% in 13 of 16 patients with AF recurrence; specificity: 75.5% in 37 of 49 patients without AF recurrence; sensitivity of LA volume: 81.3% in 13 of 16 patients with AF recurrence; specificity: 69.4% in 34 of 49 patients without AF recurrence), and the combined estimate of both atrial volumes was incremental and additive prognostic power (sensitivity: 75% in 12 of 16 patients with AF recurrence; specificity: 93.9% in 46 of 49 patients without AF recurrence). CONCLUSIONS Both LA and RA remodeling are equally associated with post-CA AF recurrence.

Abstract
BACKGROUND Long-term clinical outcomes of diabetes mellitus (DM) patients who underwent drug-eluting stent deployment has not well investigated. METHODS AND RESULTS A total of 2,050 cases were enrolled consecutively from 50 sites in Japan into the Cypher stent Japan Post-Marketing Surveillance (Cypher J-PMS) registry, and the 3-year outcomes of DM patients were analyzed. Subjects were divided into 2 groups based on the treatment of DM (insulin-treated diabetes (IT) group, n=207; and non insulin-treated diabetes (NIT) group, n=682). Major adverse cardiac event (MACE) rates in the IT group and the NIT group were 26.0% and 14.5% at 3 years, respectively (P<0.001). There were no significant differences in stent thrombosis rates (definite and probable by Academic Research Consortium (ARC) definition) (0% and 1.08%, respectively). Multivariate analysis suggested that hemodialysis and insulin-treated DM were independent predictors for MACE, and insulin-treated DM, hemodialysis and long lesions were strong independent predictors for target-lesion revascularization (TLR). CONCLUSIONS Hemodialysis and insulin-treated DM were strong independent predictors of mortality and TLR in DM patients. These results might suggest that special attention to patients with hemodialysis and insulin-treated DM is warranted in the setting of sirolimus-eluting stent deployment for DM patients.

Abstract
In a 66-year-old male with subacute extensive anterior wall myocardial infarction, we report a change in ST vector orientation from a basal anterior to a mid anterior after coronary artery recanalization of the proximal left anterior descending coronary artery with rotational atherectomy. The ST vector shift on the frontal plane after recanalization was consistent with a change toward more distal location of the ischemia on thallium-201 single photon emission computed tomography images compared to the findings during an exercise test before intervention. These findings may be correlated with local occlusion caused by distal microvascular embolization which was not visualized on coronary angiography following recanalization.

Abstract
BACKGROUND A reliable, noninvasive assessment of plaque configuration would constitute an important step forward for predicting complications following percutaneous coronary intervention (PCI). Multislice computed tomography (MSCT) holds promise with respect to allowing for differentiation of coronary lesion configuration. However, it has not yet been clarified whether the characteristics of coronary artery plaque measured by MSCT predict complications after PCI. The aim of this study was to investigate the relationship between plaque configuration and complications after coronary intervention in patients with stable angina pectoris. METHODS MSCT was performed in patients with angina pectoris who were scheduled for PCI prospectively, and 26 patients (70 +/- 11 years, 18 males) with coronary artery plaque in a stenotic coronary artery measured by MSCT were recruited for this study. Thirty-five plaques in the stenotic coronary lesions were divided into 3 groups based on the CT density as soft, intermediate, and hard, and were compared with the complications after PCI. RESULTS The soft plaque group before PCI (n = 11) was significantly associated with the appearance of slow flow (n = 4) or a compromised side branch (n = 1) after PCI, whereas the hard plaque group before PCI (n = 17) was associated with the appearance of dissection (n = 2) or perforation (n = 1) after PCI (P = 0.004). The intermediate plaque group (n = 7) had only one complication, a compromised side branch (n = 1). CONCLUSION Coronary arterial plaque characterized by MSCT can predict intervention-related complication. It may be important for the risk stratification of the patients scheduled to undergo PCI to investigate plaque configuration by MSCT.

Abstract
We investigated simultaneously the correlations between dobutamine-induced contractile reserve (CC), thallium-201 reverse redistribution (RR) and a mismatch between perfusion and metabolism (MM) to the magnitude of functional recovery. In 32 patients with coronary angioplasty early after infarction, echocardiography was performed at low-dose dobutamine stress within 1 week and at resting state at 1 month. Thallium-201/iodine-123 beta-methyl-iodophenyl pentadecanoic acid (BMIPP) dual-isotope single photon emission tomography was performed at 1 month. Wall motion and the uptake of each tracer were scored as 0 to 2 in the infarct-related segments, and CC, RR, and MM were evaluated in the infarct-related segments. In 71 akinetic or dyskinetic segments before reperfusion, the initial thallium-201 uptake and initial BMIPP uptake scores and the 4 hour redistribution thallium-201 uptake scores were less severe in the group with complete functional recovery (group A), followed by the group with incomplete recovery (group B) and then the group with no recovery (group C) (each P < 0.0001). CC was the greatest in group A, followed by group B, and then group C (76.2% in 16/21, 60% in 15/25, 36% in 9/25, P = 0.0212). RR and MM were greater in group B (52% in 13 and 64% in 16) than in groups A and C (19% in 4 and 8% in 2, 33.3% in 7 and 24% in 6, P = 0.0013 and P = 0.0113). The intensity of functional damage reflects perfusion and metabolism, but the delayed and incomplete functional recovery after reperfusion may be closely related to RR, MM, and CC.

Abstract
The optimal diagnostic approaches using contractile reserve, perfusion, and free fatty acid metabolism together for identifying myocardial stunning after reperfusion have not been clarified in the clinical setting. We investigated the usefulness of simultaneous evaluation of these parameters during myocardial stunning to predict the functional recovery in infarct-related myocardium after reperfusion. In 43 patients (60.7 +/- 10.4 years) with successful coronary angioplasty early after a first myocardial infarction, low-dose (5 to 10 microg/kg/min) dobutamine stress thallium-201/iodine-123 beta-methyl-iodophenyl pentadecanoic acid (BMIPP) dual-isotope single photon emission computed tomography was performed with echocardiography in the acute phase within 1 week after reperfusion. Regional wall motion and the uptake of each tracer were obtained simultaneously in the infarct-related segments. In 93 segments with dyssynergy in the acute phase after reperfusion, the sensitivity, specificity, and accuracy using contractile reserve for predicting the final functional recovery in the chronic phase more than 3 months after PTCA were 81.3%, 67.2%, and 72%, respectively. More accurate predictions were obtained by simultaneous measurements of thallium-201 and BMIPP uptakes (93.8%, 66.7%, and 79.4%, respectively). The final functional recovery in the stunned myocardium after early reperfusion following acute myocardial infarction was predicted more accurately by simultaneous evaluation of these parameters at dobutamine stress testing.

Abstract
OBJECTIVES Primary coronary atherosclerotic lesions(de novo lesions) are a type of inflammatory vascular disease. Restenotic lesions after percutaneous coronary intervention mainly consist of proliferative vascular smooth muscle cells. Recent studies have demonstrated that locally synthesized cytokines, including chemokines, are important in both these coronary lesions. Monocyte chemoattractant protein(MCP)-1 and macrophage colony-stimulating factor(M-CSF) are two of the associated chemokines, but their role in coronary artery disease has not been sufficiently clarified. This study investigated the expression of MCP-1 and c-fms/M-CSF receptor in human coronary tissues. METHODS Histological and immunohistochemical studies used samples obtained from patients who underwent directional coronary atherectomy(28 de novo lesions and 16 restenotic lesions). The following primary antibodies were used: anti-MCP-1, anti-c-fms, anti-macrophages and anti-alpha-smooth muscle actin. RESULTS Focal accumulation of macrophage-derived foam cells, thrombus, cholesterol clefts and calcification tended to be more frequent in de novo lesions than in restenotic lesions. On the other hand, restenotic lesions mainly consisted of stellate vascular smooth muscle cells and extracellular matrix. The expression of MCP-1-positive cells almost coincided with the macrophages. In contrast, staining for MCP-1 was little seen in the stellate vascular smooth muscle cells. Expression of c-fms was found in both macrophages and stellate vascular smooth muscle cells. Expression patterns of MCP-1 and c-fms exhibited no difference between the two lesion types. CONCLUSIONS Both MCP-1 and the M-CSF/c-fms system are involved in the atherogenesis of de novo lesions. However, the M-CSF/c-fms system, rather than MCP-1, is more important in the late stage of restenosis.

Abstract
BACKGROUND Hepatocyte growth factor (HGF) and vascular endothelial growth factor (VEGF) are endothelial cell-specific growth factors, but the production of these growth factors in cardiomyocytes has also been demonstrated. However, there have been no reports focusing their attention on the changes in these growth factors after coronary intervention. We investigated the time-course changes of the serum VEGF and HGF levels in angina pectoris (AP) and acute myocardial infarction (AMI). METHODS The serum HGF and VEGF levels were measured in 60 patients with AP, in 62 patients with AMI (AP, before heparin administration, and at 24 and 48 hours, and one week after intervention; AMI, before heparin, and at 48 and 72 hours, and one, two, three and four weeks) and in 56 patients with neurocirculatory asthenia as controls. We defined the patients with remodelling who showed an increase in left ventricular end-diastolic volume index (LVEDVI) in the sub-acute phase of AMI. RESULTS Hepatocyte growth factor levels in the AP and AMI were significantly higher than that in the control (p<0.0001). The AMI level was also significantly higher than AP (p<0.001). In the AMI and AP, HGF peaked at 48 hours. Vascular endothelial growth factor level in the AMI was significantly higher than that in the control and AP (p<0.0001). In the AMI, VEGF peaked at two weeks. There was a significant positive correlation between the peak VEGF and LVEDVI in the sub-acute phase of AMI (p=0.0089, r=0.436). Peak VEGF in the remodelling (+) group was significantly higher than that in the remodelling (-) group (p<0.001). In the AP, VEGF was unchanged. CONCLUSION While both myocardial and vascular damage contribute to an increase in HGF level, vascular damage is not associated with the increase in VEGF. Vascular endothelial growth factor might be related to left ventricular remodelling in the sub-acute phase of myocardial infarction.

Abstract
We recently reported the cloning of the REIC/Dkk-3 gene, whose expression was shown to be down-regulated in many human immortalized and tumor-derived cell lines [T. Tsuji et al. (2000) Biochem. Biophys. Res. Commun. 268, 20-24]. In the present study, we demonstrated that expression of the exogenous REIC/Dkk-3 gene in tumor cells inhibited cell growth. Furthermore, the level of REIC/Dkk-3 mRNA in normal human cells was lowest in the late G(1) phase during the cell cycle. Then we found that the expression of REIC/Dkk-3 was significantly down-regulated in surgically resected non-small-cell lung carcinomas. We determined the REIC/Dkk-3 locus on chromosome 11p15, where loss of heterozygosity has frequently been observed in human tumors. These findings indicate that REIC/Dkk-3 may function as a tumor suppressor.

Abstract
Hepatocyte growth factor (HGF) is an endothelial cell specific growth factor involved in the repair of endothelial cells and collateral formation, however, the role for coronary artery disease is still unknown. We measured serum HGF level in various coronary artery diseases to examine the clinical significance. Serum HGF level was measured using the enzyme-linked immunosorbent assay method in patients with stable effort angina pectoris (n = 26), old myocardial infarction (n = 18), unstable angina pectoris (UAP; n = 10) and acute myocardial infarction (AMI; n = 21). As a control group, we selected 11 patients with neurocirculatory asthenia. Blood samples from peripheral veins were collected at cardiac catheterization before heparin administration. In the AMI group, blood samples were also collected at 48, 72 hr, 1, 2, 3 and 4 weeks from the peripheral veins and 48 and 72 hr after reperfusion from the coronary sinus. Serum HGF level was significantly higher in the UAP (0.41 +/- 0.12 ng/ml, p < 0.001) and AMI groups (0.38 +/- 0.26 ng/ml, p < 0.05) compared to the control group (0.19 +/- 0.09 ng/ml). Serum HGF level peaked 48 hr after reperfusion in both the peripheral veins (0.42 +/- 0.16 ng/ml) and coronary sinus (0.58 +/- 0.23 ng/ml) in the AMI group, with a significantly higher level in the coronary sinus than the peripheral veins (p < 0.05). No significant correlation between peak HGF level in the peripheral veins and peak creatine kinase (CK), CK-MB, ejection fraction and cardiac index was observed. Serum HGF was elevated in acute coronary syndrome, indicating advanced endothelial cell damage. HGF is produced, at least partially, in the heart in patients with AMI. Serum HGF level may be useful to detect endothelial cell damage rather than myocardial cell damage.

Abstract
We have established a mouse model for scleroderma induced by repeated local injections of bleomycin (BLM). Daily injection of BLM at a dose of >10 microg per ml for 4 wk induced histologic changes of dermal sclerosis, but not fibrosis, with thickened and homogenous collagen bundles and cellular infiltrates in BALB/C mice, whereas clinical signs of scleroderma were not apparent. In addition, lung fibrosis was also induced preceding the cutaneous changes. Sclerotic changes were not found in other sites of the skin distant from the injection site. Dermal sclerosis could also be induced by injecting BLM only every other day. The sclerotic changes of the dermis were sustained after ceasing BLM applications for at least 6 wk. Mast cells gradually increased in number as the sclerotic changes developed. Marked degranulation of mast cells was observed with elevated histamine release. The amount of hydroxyproline in skin was significantly increased at 4 wk of BLM treatment as compared with that in untreated or phosphate-buffered saline-treated mice. Anti-nuclear antibody was detected in serum of BLM-treated mice. Transforming growth factor-beta1 mRNA was detected at an early phase, while transforming growth factor-beta2 mRNA was strongly expressed at 4 wk when the sclerotic features were prominent. These results suggest that dermal sclerosis induced by BLM closely resembles systemic sclerosis both histologically and biochemically. Our mouse model can provide a powerful tool of inducing dermal sclerosis to examine the pathogenesis and the therapeutic approach of scleroderma.

Abstract
Tec is a non-receptor type tyrosine kinase which is tyrosine phosphorylated and activated upon stimulation of hematopoietic cells with various cytokines. The role of Tec in G protein-coupled receptor- and integrin-mediated signalings has not been elucidated. We therefore investigated the regulation of Tec in human blood platelets. Tec was rapidly tyrosine phosphorylated in response to platelet agonists which activate G protein-coupled receptors such as thromboxane A2 analog (U46619), thrombin, and thrombin receptor activating peptide (TRAP). TRAP-induced phosphorylation in Tec was significantly reduced under the conditions which abrogate fibrinogen binding to GP IIb-IIIa and subsequent platelet aggregation. However, TRAP induced significant levels of the phosphorylation even under these conditions and also in thrombasthenic platelets which lack functional GP IIb-IIIa molecules, suggesting that activation of G-protein-coupled receptor causes the phosphorylation. To clarify whether integrin engagement by itself causes the phosphorylation in Tec, we examined the state of the phosphorylation in platelets activated by integrin engagement. Platelet adhesion to immobilized fibrinogen or collagen induced significant levels of the phosphorylation. Furthermore, Tec was translocated to cytoskeleton in response to TRAP in a manner dependent on platelet aggregation, suggesting that Tec can be a component of integrin-mediated signalings. These results collectively indicate that Tec is involved in G protein-coupled receptor- and integrin-mediated signalings in human blood platelets.

Abstract
A patient with chronic myelogenous leukemia who underwent transformation from the accelerated phase to the chronic phase with interferon-alpha treatment is reported. On admission, the numbers of myeloblasts and promyelocytes in the peripheral blood and bone marrow were 7.0% and 12.8%, respectively. The platelet count was 633.6 x 10(4)/microliter, and megakaryocytes were frequent in the bone marrow. In the accelerated phase, cytogenetic analyses revealed a hypotetraploid and a hypooctoploid cell population with two and four Philadelphia chromosomes, respectively, in the bone marrow specimen. The hypooctoploid clone disappeared with administration of interferon-alpha and the hypotetraploid clone also subsequently disappeared.

Abstract
Effect of human recombinant thrombopoietin (TPO) on platelet activation in vitro was studied. Although TPO itself did not cause platelet aggregation, it upregulated ADP-induced aggregation, especially the second wave of aggregation. This effect was dose-dependent for up to 5 ng/ml of TPO. When platelets were activated by epinephrine, collagen, or alpha-thrombin, similar effect was observed. However, TPO did not affect A23187- or PMA-induced aggregation, suggesting that TPO may have modulated the signal transduction pathway upstream of inositol 1,4,5-trisphosphate and diacylglycerol production. TPO also upregulated thrombin-induced alpha-granule secretion. To clarify the involvement of protein tyrosine phosphorylation, platelets were activated by TPO and/or suboptimal concentration of ADP, then tyrosine phosphorylation was detected by immunoblot analysis, using anti-phosphotyrosine monoclonal antibody. TPO by itself caused significant tyrosine phosphorylation of 146, 130, 122, 108, 97, 94, and 88 kDa proteins. Further, by using antibodies against signal transduction molecules for immunoprecipitation, we observed the significant tyrosine phosphorylation in Jak2 and Tyk2 molecules after TPO-stimulation. The results of the present experiment clearly indicate that TPO directly activated platelets and modulated intracellular signal transduction pathway.

Abstract
The mechanism by which granulocyte-macrophage colony-stimulating factor (GM-CSF) lowers plasma cholesterol levels is not well understood. We tested recombinant human GM-CSF (rhGM-CSF) on plasma cholesterol and triglycerides in rabbits and attempted to determine the mechanisms of the cholesterol-lowering effect. rhGM-CSF (20 micrograms.kg-1.d-1) was administered to normal and cholesterol-fed rabbits for 2 weeks and to Watanabe heritable hyperlipidemic (WHHL) rabbits for 1 week. The administration of rhGM-CSF markedly lowered cholesterol and triglycerides, an effect that persisted in normal and cholesterol-fed rabbits even after termination of treatment. The cholesterol-lowering effect of rhGM-CSF was also observed in WHHL rabbits. rhGM-CSF was capable of stimulating granulocyte-macrophage colony formation in vitro in rabbits with an effect comparable to that in humans. Northern blot analysis with rabbit very-low-density-lipoprotein (VLDL) receptor cDNA revealed that rhGM-CSF increased the levels of VLDL receptor mRNA in muscle of rabbits after only 1.5 hours of treatment compared with control (2.6-fold), with the 1.5-fold increase following a 5-day administration. No changes in the levels of LDL receptor mRNA in liver, spleen, and bone marrow were observed in the treated rabbits. These findings suggest that the cholesterol-lowering effect of rhGM-CSF may be mediated by enhancement of macrophage functions in lipid metabolism and the increase in mRNA for VLDL receptor in rabbits.

Abstract
The incidence of coronary ectasia (CE) and the relationship between CE and coronary spasm that was said not to be apt to occur in patients with CE were studied. The study consisted of 1,373 patients (including 1,008 patients with ischemic heart disease) who underwent cardiac catheterization. In 74 patients with CE, coronary spasm was tested in 33 patients subjected to acetylcholine (ACh) provocation and in 17 patients subjected to ergonovine (Ergo) provocation. CE was found in 74 patients (5.4%), and its incidence was significantly higher (6.7%) in patients with ischemic heart disease. In addition, ACh and Ergo provocation tests gave positive results in 12 (36%) and 4 patients (24%), respectively. Spasm was not provoked as frequently in the ectatic portion as elsewhere. In addition, spasm was often found at the borders of the ectatic portion in both provocation tests. The incidence of coronary ectasia was higher than that described in previous reports, and coronary spasm was more often observed at the borders between ectatic and normal portions than elsewhere.

Abstract
Human parvovirus B19 (B19) has been shown to be associated with erythema infectiosum. Recently, it was reported that when a pregnant woman is infected with B19, the fetus in her uterus sometimes becomes hydropic and results in a stillbirth. But no epidemiologic study of pregnant women in Japan has been performed yet. We have established an in vitro propagation system of B19 virions and an assay system for detecting anti-B19 antibody by indirect immunofluorescence (IF) staining. We examined the positive rate of anti-B19 antibody among 337 normal blood donors, 329 normal pregnant women, 23 early aborted women and 24 non-immune hydrops fetalis cases by IF staining. The positive rate for anti-B19 IgG among normal blood donors increased with age. It was 22% aged 21 to 30, 44% aged 31 to 40, 65% aged 41 to 50, and 76% aged 51 to 60, respectively. Anti-B19 IgG was detected in 33% of 329 of normal pregnant women. The anti-B19 IgG positive rate was 26% in pregnant women in their twenties and 44% in those in their thirties. There was a significant difference between the two generations. The results show that more than half the women in their twenties and thirties risk B19-infection during pregnancy. Nine of twenty-three early aborted women were positive for anti-B19 antibody. Among six pregnant women who were positive for anti-B19 IgM, four delivered normal babies and the others aborted artificially or spontaneously. Anti-B19 IgG and IgM of twenty four non-immune hydrops fetalis (NIHF) were examined and four cases were found to be anti-B19 IgG positive.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We administered 20 ml of Yomeishu (YMS) twice a day before meals for 12 weeks to 50 post-operative patients in gynecology and then inquired into their subjective 20 symptoms (sense of fatigue, insomnia, headache and heavy headedness, appetite, stomach-ache, abdominal inflation, vertigo, lumbago, etc.) The YMS group showed a significant improvement on 14 items compared with the control group. On the whole, a great improvement was observed in the YMS group with serious subjective symptoms as well, and there were significant differences for general condition, sense of fatigue, and coldness in extremities.

Abstract
We reviewed our records for the last 10 years and found three of the 36 patients with neuroblastoma did not excrete significantly increased quantities of catecholamine metabolites in urine. All of these tumors were histologically characterized by small round cells and possessed a few dense core granules on the electron microscopic examination. All of them were reacted with anti-neuron-specific enolase (NSE) antibodies, OKB2, PI153/3 monoclonal antibodies (MoAbs). The HNK-1, BA-1, and SJ-9A4 MoAbs reacted with two out of three. One of them demonstrated a reciprocal translocation involving the short arm deletion of chromosome 1. This multidisciplinary study has been helpful in making more accurate diagnoses for neuroblastoma without classical clinical characters.

Abstract
A study was done to investigate the involvement of interferon (IFN) in immunological acceptance of fetal allograft. IFN was induced by stimulating OK-432 from lymphocyte of pregnant and nonpregnant women as well as men. There was no difference in the IFN titer in these groups. In pregnant women there was no difference between trimesters, either. In addition, we examined the influence of sex steroid hormones such as progesterone and estrogen on IFN production by the lymphocytes of women and men. Generally, each steroid hormone suppressed the production of IFN. However, the extent of suppression varied with the concentration of hormones, resulting in different suppression curves for men and women in a physiological concentration. Differences in response by men and women were also noticed when interleukin 2 was added to examine whether it could reduce the suppression by steroid hormone. This unique sensitivity of female lymphocyte to steroid hormones may play a role in successfully taking a fetal allograft in pregnancy.
