Abstract
In addition to its role in pyroptosis and inflammatory cytokine maturation, caspase-4 (CASP4) also contributes to the fusion of phagosomes with lysosomes and cell migration. However, its role in cell division remains elusive. In this study, we demonstrate that CASP4 is indispensable for proper cell division in epithelial cells. Knockout of CASP4 (CASP4 KO) in HepG2 cells led to delayed cell proliferation, increased cell size, and increased multinucleation. In mitosis, CASP4 KO cells showed multipolar spindles, asymmetric spindle positioning, and chromosome segregation errors, ultimately increasing DNA content and chromosome number. We also found that phalloidin, a marker of filamentous actin, increased in CASP4 KO cells owing to suppressed actin depolymerization. Moreover, the levels of actin polymerization-related proteins, including Rho-associated protein kinase1 (ROCK1), LIM kinase1 (LIMK1), and phosphorylated cofilin, significantly increased in CASP4 KO cells. These results suggest that CASP4 contributes to proper cell division through actin depolymerization.

Abstract
Inflammation is observed in many tumors, which affects metastasis, infiltration, and immune escape and causes poor differentiation of the cancer cells. However, the molecular basis underlying the relationship between inflammation and poor differentiation in tumors has not been identified. In this study, we demonstrate that angiopoietin-like protein-8 (ANGPTL8), which is induced by stress stimuli such as inflammation, is involved in the maintenance of the undifferentiated state of clear cell renal cell carcinoma (ccRCC) cells. ANGPTL8 is also involved in the production of chemokines that attract immune suppressor cells to the tumor microenvironment. ANGPTL8 sustains the continuous production of chemokines by activating the NF-κB signaling pathway and maintains the undifferentiated state of ccRCC cells. Finally, ANGPTL8 is induced by STAT3 signaling, which is activated by immune cells in the tumor microenvironment. These results support a role for ANGPTL8 in determining the properties of ccRCC by hampering tumor cell differentiation and establishing the tumor microenvironment.

Abstract
Background As a type of welfare technology, care robotics is now widely seen as a potential aide to rehabilitation, increasing independence and enhancing the wellbeing of people with disabilities and older adults. Research into and development of care robots have both been vigorously promoted in North America, Europe and Asia, and the competition for technological advancement in robotics is becoming fierce. AI ethics and policy guidelines are being established. However, there are still differences in attitudes and perceptions, as well as national policies regarding this type of welfare technology. Moreover, despite the anticipated usefulness, it is believed that progress has been slow in the diffusion of care robots. Purpose In order to explore how public discourses support technological innovation, such as care robots, while preparing society for potential risks and impact, we sought to ascertain whether public discourse on care robots varies from region to region. For example, what are the hopes and promises associated with care robots and what are the concerns? Methods To address these questions, this article explored how care robots have been portrayed in five major broadsheet newspapers in five jurisdictions in Asia and Europe (France, Great Britain, Hong Kong SAR, Ireland and Japan). We obtained 545 articles for the period between January 2001 and September 2020, more than half of which originated in Japan. A thematic analysis was conducted of these articles written in four languages (Chinese, English, French and Japanese). Results Positive and negative narratives were teased out, alongside other key prominent themes identified, such as Japan as the land of robots, the pandemic, and the impact of robots on the economy. As the number of robot-related articles grew from the year 2012 onwards, narratives became more nuanced in European newspapers, but not in Asian ones. Furthermore, recent articles began to address the social and relational impact of care robots, while providing concrete examples of improvements in the quality of life for users. Further careful examination will be necessary in the future in order to establish the impact of robotics use in rehabilitation for people with disabilities, older adults, their carers and society at large.

Abstract
Abstract
Background
The pandemic heightened the sense of security and safety in care settings, with cleanliness and infection control becoming an even more important aspect of care delivery. Although the impact of new welfare technology on health and social care has been discussed in recent years, few studies have reported the implementation processes or human-robot interactions in care facilities in different cultural settings. The aims of this interdisciplinary research therefore were to understand needs and aspects that have to be considered for implementing an assistive robot, and to explore user perceptions, and the process by which the robots are adopted in Ireland and Japan.
Methods
An original air-disinfection robot (V-Air) was developed by Akara Robotics, as part of research project “Harmonisation towards the establishment of Person-centred, Robotics-aided Care System” (Toyota Foundation, D18-ST-0005). Prior to its instalment in a rehabilitation centre in Dublin, semi-structured interviews were conducted, and observations carried out with seven care professionals, as they interacted with V-Air. The robot was then trialled for eight weeks (March-May 2022) in selected areas of the facility. After four weeks, the users filled out the System Usability Score and were asked questions at the end of the trial. Their scores and answers to the questions revealed staff perceptions and attitudes to care robots.
Results
Overall, the users had positive perceptions of V-Air and its usability. Initial differences existed in staff’s confidence levels, depending on prior experiences with technologies. Collective sensemaking was observed, particularly, around care delivery processes and robot functionalities. The adoption process was facilitated by several factors such as the timing of introduction, user-centred design, concept of care and organisational support.
Conclusion
The findings suggest that the introduction of care robots in care settings can offer an additional layer of organisational safety, while highlighting the significance of the iterative process in adopting assistive technologies.

Abstract
Abstract
Background
Although the impact of new technology on the workplace has been discussed for many years, little has been reported regarding the effect of new technology in nursing homes. The aim of the research was to test the effect of a safety monitoring device on night-time work patterns.
Methods
A monitoring sensor with an infrared camera was installed in Tokyo-based residential nursing homes in April 2020. A pre/post intervention and observation study was conducted before and after the introduction of the device. Four care professionals worked each night in pairs (one person providing care, and the other observing and keeping minute-by-minute records of task and time allocated to each task. The tasks were divided into 33 items). The data were collected by two pairs at three different nights for pre-intervention and from two pairs at two nights for post-intervention. Ten care professionals participated in the study, and they were looking after 30 older adults (86.8 +/- 6.8 years old).
Results
The total time for executing various tasks marginally increased from 978 mins to 1033 mins. However, statistically significant changes were found mainly among items related to medical care and safety. While nurse call response time decreased significantly, the proportion of time allocated to personal care such as vital checks (from 1 to 2 percent) and mobility (from 4 to 9 percent) assistance doubled. Break time also increased significantly.
Conclusion
While the introduction of a safety monitoring system did not radically reduce the workload, it changed the patterns of caregiving during the night shift. Some behavioural changes were directly caused by functions of the system, while others were by-products. Staff’s break length also increased. The findings suggest that the introduction of Information and Communication Technology (ICT) in nursing homes has the potential to release time to care.

Abstract
A triple antiemetic therapy combining aprepitant (APR) with conventional double antiemetic therapy, including 5-hydroxytryptamine 3 receptor antagonist (5-HT₃-RA) and dexamethasone (DEX), is recommended for preventing chemotherapy-induced nausea and vomiting induced by a carboplatin (CBDCA) regimen. However, consensus on the additive effects of APR for gynecological patients on a combined regimen of paclitaxel and CBDCA (TC regimen) has yet to be reached. This retrospective study investigated the antiemetic effects of palonosetron and DEX (PD therapy) and granisetron and DEX with APR (GDA therapy) in patients with gynecologic cancer and who underwent their first TC regimen cycle between April 2017 and March 2020 at the Gunma University Hospital Outpatient Chemotherapy Center. The results showed that the complete response rate of the 92 patients who underwent PD therapy (PD group) and the 46 patients who underwent GDA therapy (GDA group) were both 80.4% (p = 1.000), and the complete control rates of the PD and GDA groups were 78.3% and 80.4%, respectively (p = 0.828), resulting in no significant difference. Furthermore, we observed no significant difference between the PD and GDA groups in the incidence of grade ≥2 nausea, vomiting, and anorexia (nausea: 7.6% vs. 0%, p = 0.095; vomiting: 4.3% vs. 0%, p = 0.301; and anorexia: 9.8% vs. 2.2%, p = 0.164). Concerning adverse events, compared to the PD group, the GDA group showed significantly higher incidence of grade ≥2 malaise (7.6% vs. 19.6%, p = 0.039). Given the lack of difference in the antiemetic effects of PD and GDA therapies, antiemetic therapy should be selected carefully for individual patients by accounting for the incidence of adverse reactions and interactions with APR.

Abstract
Wnt/β-catenin is believed to regulate different sets of genes with different coactivators, cAMP response element-binding protein (CREB)-binding protein (CBP) or p300. However, the factors that determine which coactivators act on a particular promoter remain elusive. ICG-001 is a specific inhibitor for β-catenin/CBP but not for β-catenin/p300. By taking advantage of the action of ICG-001, we sought to investigate regulatory mechanisms underlying β-catenin coactivator usage in human pancreatic carcinoma PANC-1 cells through combinatorial analysis of chromatin immunoprecipitation-sequencing and RNA-sequencing. CBP and p300 preferentially bound to regions with the TCF motif alone and with both the TCF and AP-1 motifs, respectively. ICG-001 increased β-catenin binding to regions with both the TCF and AP-1 motifs, flanking the genes induced by ICG-001, concomitant with the increments of the p300 and AP-1 component c-JUN binding. Taken together, AP-1 possibly coordinates β-catenin coactivator usage in PANC-1 cells. These results would further our understanding of the canonical Wnt/β-catenin signaling divergence.

Abstract
Abstract
Background
As one of the most rapidly ageing economies, Japan is currently faced with a shortage of care workers and relatively low intakes of migrant workers. While there is a shortage of health and social care professionals, the retention of professional staff is paradoxically becoming more difficult. The environment in domiciliary care is often associated with heavy and challenging workload. Robotics-aided care has been proposed in Japan to ameliorate the situation. While some positive effects of such a novel care model have been reported, the mechanism by which the technology-driven system improved care and residents’ quality of life remains unclear.
Methods
Using a case study approach, this paper examines one of the nursing homes in Japan where robotics-aided care was introduced. The organisational mechanism was analysed through documents and semi-structured staff interviews from the perspective of safety science. The key attributes of organisational resilience are: anticipating; responding; monitoring and learning. The paper details some of the tools that predated the introduction of the socially assistive robots and monitoring system in the care home. The interviews were conducted with 16 health and social care professionals.
Results
The results of the technological intervention itself demonstrated improved scores for the quality of life among the residents. However, the subsequent interview data highlight the significance of an organisational context in which technologies can be effectively introduced and implemented in nursing homes. The organisation had several well-trained care professionals, including the leaders, who share the mental map of ‘person-centred care’ and the ‘capability approach’. In addition, some tools were used to ‘visualise’ staff practice. Health and social care professionals pointed out some challenges surrounding the human-technology interface.
Conclusion
In order to understand the effectiveness and potential issues of the ICT robotics solution in care for older people, future research should investigate the human-technology interface and the interconnectedness between work system, care processes and outcomes.

Abstract
Peritoneal metastasis is a common mode of spread of ovarian cancer. Despite therapeutic advances, some patients have intractable peritoneal metastasis. Therefore, in-depth characterization of the molecular mechanism of peritoneal metastasis is a key imperative. Angiopoietin-like protein 2 (ANGPTL2) is an inflammatory factor which activates NF-κB signaling and plays an important role in the pathogenesis of various inflammatory diseases including cancers, such as lung and breast cancer. In this study, we examined the role of ANGPTL2 in ovarian cancer peritoneal metastasis. We observed no difference of cell proliferation between ANGPTL2-expressing and control cells. In the mouse intraperitoneal xenograft model, formation of peritoneal metastasis by ANGPTL2-expressing cells was significantly decreased compared to control. In the in vitro analysis, the expressions of integrin α5β1, α6, and β4, but not those of αvβ3, α3, α4, and β1, were significantly decreased in ANGPTL2-expressing cells compared to control cells. ANGPTL2-expressing cells showed significantly inhibited adherence to laminin compared to control. In addition, we observed upregulation of anoikis (a form of programmed cell death occurring under an anchorage-independent condition) and significant decrease in the expression of Bcl-2 in ANGPTL2-expressing cells as compared to control cells. These results suggest that ANGPTL2 expression in ovarian cancer cells represses peritoneal metastasis by suppressing anoikis resistance.

Abstract
OBJECTIVE Breakfast skipping is reported to be associated with obesity in children and younger populations; however, few studies report the association among elderly. The purpose of this study was to investigate the relationships between breakfast skipping and obesity prevalence among elderly. DESIGN Cross-sectional study. SETTING Community-dwelling elderly in Nara, Japan. PARTICIPANTS 1052 elderly participants (mean age: 71.6 years). MEASUREMENTS Obesity and breakfast skipping were defined as body mass index of ≥25 kg/m2 and skipping breakfast one or more times per week, respectively. RESULTS Two hundred and seventy-two participants (25.9%) were classified as obese and forty-one (3.9%) were as breakfast skippers. Obesity prevalence was significantly higher in breakfast skippers than in breakfast eaters (43.9% vs. 25.1%, P = 0.007). In multivariable logistic regression analysis adjusted for potential confounders (age, sex and alcohol consumption), breakfast skippers showed significantly higher odds ratio (OR) for obesity than breakfast eaters (OR, 2.23; 95% confidence interval, 1.17-4.27; P = 0.015), which continued to be significant after further adjustment for socioeconomic status. In addition, breakfast skippers showed significantly lower daily potassium (P <0.001) and dietary fibre intakes (P = 0.001) and lower subjective physical activity (P = 0.035) than breakfast eaters. CONCLUSIONS Breakfast skipping was significantly associated with obesity among elderly. Poor diet quality and physical inactivity may be potential intermediators underlying the association between breakfast skipping and obesity.

Abstract
AIM To investigate whether Aδ and C fibre pain threshold values, measured using intra-epidermal electrical stimulation (IES), in people with and without Type 2 diabetes are useful in evaluating diabetic polyneuropathy (DPN) severity. METHODS Aδ and C fibre pain threshold values were measured in Japanese people with (n = 120) and without (n = 76) Type 2 diabetes by IES. Nerve conduction studies and other tests were performed to evaluate diabetic complications. RESULTS Aδ and C fibre pain threshold values were high in people with diabetes compared with control subjects (Aδ fibre: 0.050 vs. 0.030 mA, P < 0.01; C fibre: 0.180 vs. 0.070 mA, P < 0.01). Participants with diabetes and neuropathy had significantly higher Aδ and C fibre pain threshold values than participants without neuropathy (Aδ fibres 0.063 vs. 0.039 mA, P < 0.01; C fibres 0.202 vs. 0.098 mA, P < 0.05). C fibre pain threshold values were significantly higher in participants with diabetes and diabetic microvascular complications than in participants without complications. Threshold values increased with complication progression. When DPN was diagnosed according to the Diabetic Neuropathy Study Group in Japan criteria, the cut-off for the C fibre pain threshold values was 0.125 mA (area under the curve 0.758, sensitivity 81.5%, specificity 61.5%). The IES test took less time (P < 0.01) and was less invasive (P < 0.01) than the nerve conduction studies. CONCLUSIONS Intra-epidermal electrical stimulation is a non-invasive and easy measurement of small fibre pain threshold values. It may be clinically useful for C fibre measurement to diagnose early DPN as defined by the Diabetic Neuropathy Study Group in Japan criteria.

Abstract
Lung cancer cells, particularly those of non-small-cell lung cancer, are known to express Nectin-4. We previously generated a recombinant measles virus that uses Nectin-4 as its receptor but cannot bind its original principal receptor, signaling lymphocyte activation molecule (SLAM). This virus (rMV-SLAMblind) infects and kills breast cancer cells in vitro and in a subcutaneous xenograft model. However, it has yet to be determined whether rMV-SLAMblind is effective against other cancer types and in other tumor models that more closely represent disease. In this study, we analyzed the anti-tumor activity of this virus towards lung cancer cells using a modified variant that encodes green fluorescent protein (rMV-EGFP-SLAMblind). We found that rMV-EGFP-SLAMblind efficiently infected nine, human, lung cancer cell lines, and its infection resulted in reduced cell viability of six cell lines. Administration of the virus into subcutaneous tumors of xenotransplanted mice suppressed tumor growth. In addition, rMV-EGFP-SLAMblind could target scattered tumor masses grown in the lungs of xenotransplanted mice. These results suggest that rMV-SLAMblind is oncolytic for lung cancer and that it represents a promising tool for the treatment of this disease.

Abstract
WHAT IS KNOWN AND OBJECTIVE Polymorphisms in the gene encoding CYP4F2 may partly explain the variability in warfarin maintenance dose by altering the metabolism of vitamin K. To determine the genetic factors that cause large inter-patient variability in warfarin efficacy, we investigated the relationship between serum warfarin concentration and CYP4F2 V433M (1347C>T, rs2108622) polymorphism in Japanese subjects. METHODS Gene variations in VKORC1, CYP2C9 and CYP4F2 were analysed in 126 Japanese patients treated with warfarin. The daily dosage of warfarin, concentration of S- and R-warfarin in plasma, and prothrombin time international normalized ratio (PT-INR) was used as the pharmacokinetic and pharmacodynamic indices. RESULTS AND DISCUSSION The maintenance dose of warfarin was larger in the CYP4F2 1347 CT genotype group (3·59±1·80 mg/day, P=0·027) than in the CYP4F2 CC genotype group (2·88±1·00 mg/day). CYP4F2 1347C>T polymorphism significantly affected serum R-warfarin concentration when the VKORC1-1639 genotypes are AG and GG. WHAT IS NEW AND CONCLUSION Although a significant inter-patient difference in warfarin maintenance dose was observed between the CYP4F2 CC and CT genotypes, serum S-warfarin concentration was not significantly different between them. An effect of CYP4F2 V433M polymorphism on warfarin maintenance dose was observed but was relatively small when compared to the effects of CYP2C9 and VKOR polymorphism.

Abstract
Polymorphisms in cytochrome P450 (CYP) 2C9 and the vitamin K oxide reductase complex subunit 1 (VKORC1) greatly affect the maintenance dose of warfarin. To prevent adverse events, immediate dose adjustment is required. The purpose of this study was to investigate the influence of these polymorphisms on the time taken to determine the warfarin maintenance dose for individual patients, and to assess the advantages of genotype-based dosing on initial anticoagulant therapy. We analyzed the genotypes of CYP2C9 and VKORC1 from 72 patients. The number of days taken to determine the maintenance dose was compared with the genotypes. The time taken to determine the maintenance dose of warfarin in group A (CYP2C9*1/*1, VKORC1 -1639AA), B (*1/*1, - 1639GA), C (*1/*3, - 1639AA), and D (*1/*3, - 1639GA) patients was 19 +/- 19, 28 +/- 28, 27 +/- 20 and 7 days, respectively. We analyzed the relationship between the initial dose of warfarin and the number of days required to determine the maintenance dose based on the VKORC1 genotypes. Patients with the VKORC1 - 1639AA genotype and who were initially treated with more than 3mg warfarin, required approximately 2 weeks for the maintenance dose to be determined. Patients with the VKORC1 - 1639GA genotype and the same initial warfarin dosage required approximately a month; however, patients initially treated with 5 mg of warfarin only required 9.5 +/- 5.3 days. We found a tendency that the time taken to determine the warfarin maintenance dose depends on the genotypes. Genotype-based dosing may improve initial anticoagulant therapy.

Abstract
The production of IgE, a main player in allergic disorders such as asthma and atopic dermatitis, is strictly regulated and the serum concentrations of IgE are normally kept at a much lower level than other isotypes. We found that mice deficient for the p85alpha regulatory subunit of class IA phosphoinositide 3-kinase (PI3K) produced increasing amounts of serum IgE. Purified p85alpha-/- B cells produced more IgE than wild-type B cells in vitro in response to anti-CD40 mAb and IL-4. PI3K inhibitors wortmannin and IC87114 enhanced IgE production by wild-type B cells stimulated with anti-CD40 mAb and IL-4. Under the same condition, antigen receptor cross-linking induced the expression of inhibitor of differentiation-2 and suppressed the expression of activation-induced cytidine deaminase and class switch recombination (CSR) in a PI3K-dependent manner. IgE production was also suppressed in a concentrated cell culture condition, which was completely reversed by PI3K inhibition. The selective suppression of IgE production by PI3K was also observed at a protein level after CSR. Our results indicate that PI3K negatively regulates IgE production at both CSR and protein levels.

Abstract
OBJECTIVE Patients with amyloidogenic transthyretin (ATTR) Tyr114Cys develop amyloid deposits in cerebral blood vessels, cerebral hemorrhage, and rapidly progressive dementia that presents with hereditary cerebral amyloid angiopathy (CAA). However, no treatment has been identified for CAA. Although liver transplantation has become an acceptable treatment of TTR-related amyloidosis, liver transplantation may not successfully treat CNS manifestations of the disorder. In this study, we examined the effect of liver transplantation on these manifestations of TTR-related CAA. METHODS We compared clinical courses of three patients with CAA associated with ATTR Tyr114Cys who underwent liver transplantation with those of five patients with the disorder who did not undergo liver transplantation. RESULTS The mortality and occurrence of cerebral hemorrhage and dementia in patients having transplantations were reduced compared with those in patients not having transplantations. The two groups did not differ with regard to the frequency of episodes of fluctuating consciousness and TIAs. The group undergoing transplantations had significantly smaller volumes of intracranial hemorrhage than did the no-transplantation group. CONCLUSION Liver transplantation was effective for CNS manifestations of cerebral amyloid angiopathy associated with amyloidogenic transthyretin Tyr114Cys.

Abstract
Ig class switch recombination (CSR) is triggered by the engagement of CD40 on B cells by CD40 ligand on T cells. In addition, recent studies have shown that dendritic cells (DCs) are able to directly control the CSR of B cells through B lymphocyte stimulator protein [or B cell activation factor belonging to the tumor necrosis factor family] and a proliferation-inducing ligand. We examined in this study the regulatory role of DCs in CSR and demonstrate that DCs selectively suppress IgE production from B cells stimulated by CD40 and IL-4 through two different mechanisms: by direct cell-cell interaction or by soluble factors including transforming growth factor-beta and IFN-gamma. In addition, distinct DCs utilize different mechanisms: immature bone marrow-derived dendritic cells (BMDCs) and primary lung DCs strongly inhibit IgE CSR. On the other hand, LPS-induced mature BMDCs lose the ability to inhibit IgE CSR but still suppress IgE production by decreasing IgE protein expression. These results indicate novel regulatory functions of DCs on IgE production.

Abstract
OBJECTIVE To clarify the pathogenesis of leptomeningeal amyloidosis in familial amyloidotic polyneuropathy amyloidogenic transthyretin Y114C (FAP ATTR Y114C). METHODS The authors analyzed eight FAP ATTR Y114C patients. Six patients showed CNS symptoms associated with leptomeningeal amyloidosis. To examine the function of the blood-CSF barrier and blood-brain barrier (BBB), the authors performed CSF and MRI studies. The authors also performed a histopathologic study of autopsy specimens to examine the distribution of amyloid deposition in the CNS. RESULTS CSF study showed high total protein concentrations and increased albumin CSF/serum concentration quotients (Qalb; an indication of blood-CSF barrier function). MRI with gadolinium (Gd) revealed enhancement from brainstem to spinal cord. Serial brain MRI studies with FLAIR images after Gd administration showed Gd leakage into the subarachnoid space (two patients). These findings suggested the blood-CSF barrier and BBB dysfunctions. Constructive interference in steady state (CISS) three-dimensional Fourier transformation (CISS-3DFT) sequence analysis demonstrated amyloid-induced funiculus structures joining the spinal cord and dura mater (one patient). Histopathologic study revealed intense amyloid deposition in leptomeninges, vessel walls, and parenchyma in spinal cord and the brain. These distributions of amyloid deposition are unique compared to other TTR related leptomeningeal amyloidosis. CONCLUSIONS Patients with familial amyloidotic polyneuropathy amyloidogenic transthyretin Y114C had CNS disorders related to amyloid deposition in leptomeninges, vessel walls, and parenchyma in spinal cord and the brain. The pathogenesis of CNS disorders may reflect disruption of the blood-CSF barrier and blood-brain barrier by amyloid deposition.

Abstract
The aim of this study was to compare the regressive effect of clinidipine on left ventricular mass (LVM) with that of quinapril. Sixty patients with mild essential hypertension aged more than 39 years were randomly allocated to two groups to receive cilnidipine (10 mg; n = 30) or quinapril (10 mg; n = 30). The patients underwent echocardiography before and 12 months after drug treatment. Sixteen patients in each group underwent 123I-metaiodobenzylguanidine (MIBG) cardiac imaging before and 12 months after drug treatment. In both groups systolic and diastolic blood pressures significantly decreased to similar levels. In the clinidipine group, both end-diastolic and end-systolic diameters and posterior wall thickness significantly decreased, while only end-systolic diameter significantly decreased in the quinapril group. However, LVM (206 +/- 36 g to 189 +/- 40 g, p < 0.02 for the quinapril group, 195 +/- 60 g to 171 +/- 48 g, p < 0.004 for the clinidipine group) and the LVM index (127 +/- 20 g/m2, to 116 +/- 20 g/m2, p < 0.02 for the quinapril group, 121 +/- 32 g/m2 to 106 +/- 24 g/m2 p < 0.003 for the clinidipine group) significantly decreased in both groups. Regarding MIBG imaging, in the cilnidipine group, the heart-to-mediastinum ratio significantly increased (p < 0.02) and the washout rate significantly decreased (p < 0.02) after drug treatment. In contrast, there were no significant changes in MIBG parameters in the quinapril group. Clinidipine produced a greater decrease in LVM in essential hypertension than quinapril, probably due to the long-term suppression of the cardiac sympathetic nervous system. Clinidipine is useful for hypertensive patients with left ventricular hypertrophy and may improve their prognosis.
