Abstract
BACKGROUND AND AIM Rapidly aging societies have become a major issue worldwide including Japan. This study aimed to elucidate relative changes in the characteristics of inpatients in Japan related to this issue. METHODS A total of 23 835 Japanese inpatients treated from 2010 to 2021 were enrolled (2010-2013, period I; 2014-2017, period II; 2018-2021, period III). Changes in clinical features were retrospectively analyzed based on ICD-10 diagnosis data. RESULTS The percentage of patients aged over 75 years increased over time (period I, 38.0%; II, 39.5%, III, 41.4%). Emergency admissions comprised 27.5% of all in period I, which increased to 43.2% in period II and again to 44.5% in period III (P < 0.001). In period I, gastrointestinal disease, liver disease, pancreatic-biliary disease, and other disease types were noted in 47.4%, 29.5%, 19.2%, and 3.9%, respectively, while those values were 44.0%, 18.0%, 33.9%, and 4.1%, respectively, in period III (P < 0.001). The frequency of liver disease decreased by approximately 0.6-fold from periods I to III, while that of biliary-pancreatic disease increased by approximately 1.8-fold during that time. Both percentage and actual numbers of patients with biliary-pancreatic disease increased during the examined periods. Analysis of changes in the proportion of organs affected by malignancy during periods I, II, and III showed a marked increase in cases of biliary-pancreatic malignancy (11.6%, 19.5%, 26.6%, respectively) (P < 0.001). CONCLUSION In association with the rapidly aging Japanese society, there has been an increasing frequency of biliary-pancreatic disease cases requiring hospitalization for treatment in the west Japan region of Shikoku.

Abstract
BACKGROUND/AIM Unresectable recurrence after curative treatments for hepatocellular carcinoma (HCC) is a life-limited event. Although the IMbrave050 trial (IM050) showed a favorable reduction in recurrence with adjuvant immune-combination chemotherapy, inclusion criteria of the radiofrequency ablation (RFA) group were lower risk than that of the resection group. This study aimed to elucidate the clinical features of patients treated with RFA, which really need adjuvant-chemotherapy. METHODS From 2000 to 2022, 528 patients with Child-Pugh A and HCC within the Milan criteria (MC), who met the IM050 criteria for RFA and undergone resection or RFA, were enrolled (71 years, HCV:HBV:HBV/HCV:alcohol:others = 337:44:5:53:89, multi-tumor = 138, RFA:resection = 309:219). Unresectable recurrence was defined as beyond the MC. Risk factors for recurrence beyond the MC were retrospectively evaluated. RESULTS Multivariate Cox-hazard analysis showed HCV-positive (HR 1.49), AFP-L3 > 10% (HR 1.75), and DCP > 100 mAU/mL (HR1.80) as significant prognostic factors for recurrence beyond the MC (each P < 0.05). Summing of positive factors (1 point for each) was used for scoring (AD-ON score), which showed increased positive rates for micro-hepatic vein invasion (score 0:1:2:3 = 0%:1.1%:6.6%:15.8%), micro-portal vein invasion (0:1:2:3 = 2.0%:12.1%:14.1%:31.6%), and poor differentiation (0:1:2:3 = 6.0%:6.7%:15.3%:15.8%) in the resection group associated with a greater score (each P < 0.01). In patients treated with RFA, those with greater AD-ON scores showed shorter time to recurrence beyond the MC, recurrence-free time, and overall survival (score 0:1:2:3 = no-estimation:97:66:23 months, 35:27:20:12 months, and 91:82:67:52 months, respectively, each P < 0.05). CONCLUSION HCC patients treated by RFA and with a high AD-ON score (≧2) should be considered for aggressive adjuvant-chemotherapy to prolong the period of recurrence beyond the MC.

Abstract
INTRODUCTION For predicting esophagogastric varices (EGVs), the Virtual Baveno VII Consensus Workshop has proposed a combination of liver stiffness determination and platelet count measurement using a FibroScan®. However, FibroScan® is not available at all institutions. The present study aimed to develop a simple method to predict development of EGV using only general blood examination results. MATERIALS AND METHODS A total of 1,090 hepatocellular carcinoma patients were enrolled, after excluding 956 with major portal vein tumor thrombus (Vp3/Vp4) or without upper gastrointestinal endoscopy examination results available. Those with EGV (≥ grade F2) or a history of treatment for the condition were defined as positive for significant EGV, and then clinical factors were retrospectively evaluated to determine indicators of occurrence. RESULTS Logistic multivariate analysis showed platelet count (≤12 × 104/μL) (odds ratio [OR] 3.79, p < 0.001), mALBI grade 2a (OR 1.52, p = 0.036), and mALBI 2b or 3 (OR 3.46, p < 0.001) as significant predictive factors. Based on the OR values, platelet count (≤12 × 104/μL) and mALBI grade 2b/3 were each assigned 2 points and mALBI 2a was given 1 point, with the result termed recommendation for EGV screening (REGS) score. Significant EGV occurrence was noted in 2.9% (9/311) of the patients with a REGS score 0, 11.0% (13/118) with a score 1, 19.3% (53/274) with a score 2, 29.5% (39/132) with a score 3, and 38.0% (97/255) with a score 4 (p < 0.001). CONCLUSION The findings indicate that REGS score can provide useful predictive information for development of significant EGV without the need for special equipment such as a FibroScan®.

Abstract
BACKGROUND We compared achievement rate of sufficient tacrolimus blood concentration in the early postoperative period and incidence of acute cellular rejection within 1 month after living donor liver transplantation (LDLT) between tacrolimus intravenous (IV) and oral administration groups. METHODS From October 2005 to November 2016, 61 LDLT patients administered tacrolimus, who could be genotyped for CYP3A5*3 and *1, were chosen from the electronic record database. The patients were then divided into the 2 groups (an IV group [n = 38] and an oral group [n = 23]). We defined patients with 1*1 or *1*3 as expressors and those with *3*3 as nonexpressors. Sufficient trough level tacrolimus blood concentration on postoperative day (POD) 3 was defined as 10-20 ng/mL. RESULTS Comparable concentrations were seen between the 2 groups, with mean blood concentration 13.7 ± 8.5 ng/mL in the oral group and 15.2 ± 4.3 ng/mL in the IV group. Achievement rate of sufficient tacrolimus concentration on POD 3 was significantly higher in the IV group than in oral group: 97% (37 of 38) vs 65% (15 of 23), respectively (P = .001). When we focused on achievement rate in the oral group according to CYP3A5 polymorphism, the frequency of expressors (17%) was significantly lower than that of nonexpressors (82%) (P = .016). However, in the IV group this negative influence was totally eliminated, resulting in high achievement rates regardless of CYP3A5 polymorphism. In terms of incidence of acute cellular rejection, there was no significant difference between the 2 groups (IV 32% vs oral 17%, P = .250). CONCLUSION IV administration of tacrolimus allowed us to obtain more stable control of blood concentration regardless of CYP3A5 genotype.

Abstract
Telomerase-specific replication-competent adenoviruses (Ads), i.e., TRADs, which possess an E1 gene expression cassette driven by the human telomerase reverse transcriptase promoter, are promising agents for cancer treatment. However, even though oncolytic Ads, including TRAD, are intratumorally administered, they are disseminated from the tumor to systemic circulation, causing concern about oncolytic Ad-mediated hepatotoxicity (due mainly to leaky expression of Ad genes in liver). We reported that inhibition of nuclear factor-κB (NF-κB) leads to the suppression of replication-incompetent Ad vector-mediated hepatotoxicity via reduction of the leaky expression of Ad genes in liver. Here, to develop a TRAD with an improved safety profile, we designed a TRAD that carries a liver-specific promoter-driven dominant-negative IκBα (DNIκBα) expression cassette (TRAD-DNIκBα). Compared with a conventional TRAD, TRAD-DNIκBα showed hepatocyte-specific inhibition of NF-κB signaling and significantly reduced Ad gene expression and replication in the normal human hepatocyte cell line. TRAD-induced hepatotoxicity was largely suppressed in mice following intravenous administration of TRAD-DNIκBα. However, the replication profiles and oncolytic activities of TRAD-DNIκBα were comparable with those of the conventional TRAD in human non-hepatic tumor cells. These results indicate that oncolytic Ads containing the liver-specific DNIκBα expression cassette have improved safety profiles without inhibiting oncolytic activities.

Abstract
The synthesis and properties of 2,7-diamino-1,4,8-triazanaphthalene (azaDANP) are described. AzaDANP is protonated only at a weakly acidic pH to bind to the cytosine bulge DNA duplex selectively. Upon binding of azaDANP to the cytosine bulge DNA, a new absorption band at 407 nm appears, and the absorption change of azaDANP on binding to the target is very sensitive to environmental pH with a bell-shaped pH-absorption profile.

Abstract
Clustered regularly interspaced short palindromic repeat (CRISPR)/Cas9-mediated genome engineering technology is a powerful tool for generation of cells and animals with engineered mutations in their genomes. In order to introduce the CRISPR/Cas9 system into target cells, nonviral and viral vectors are often used; however, such vectors trigger innate immune responses associated with production of type I interferons (IFNs). We have recently demonstrated that type I IFNs inhibit short-hairpin RNA-mediated gene silencing, which led us to hypothesize that type I IFNs may also inhibit CRISPR/Cas9-mediated genome mutagenesis. Here we investigated this hypothesis. A single-strand annealing assay using a reporter plasmid demonstrated that CRISPR/Cas9-mediated cleavage efficiencies of the target double-stranded DNA were significantly reduced by IFNα. A mismatch recognition nuclease-dependent genotyping assay also demonstrated that IFNα reduced insertion or deletion (indel) mutation levels by approximately half. Treatment with IFNα did not alter Cas9 protein expression levels, whereas the copy numbers of guide RNA (gRNA) were significantly reduced by IFNα stimulation. These results indicate that type I IFNs significantly reduce gRNA expression levels following introduction of the CRISPR/Cas9 system in the cells, leading to a reduction in the efficiencies of CRISPR/Cas9-mediated genome mutagenesis. Our findings provide important clues for the achievement of efficient genome engineering using the CRISPR/Cas9 system.

Abstract
A 10-year-old, female, mongrel showed hemorrhage from vulva. By magnetic resonance image (MRI) and endoscopic examination, a multipapillary mass with a grape-like appearance was found around the urethral opening. Histologically, the mass consisted of variable-sized round-, spindle-to-polygonal-shaped tumor cells including many multinuclear cells. Mitotic figures were also frequently observed. In some areas, that tumor cells were loosely arranged, with intercellular myxoid components. immunohistochemically, these tumor cells were strongly positive for vimentin and focally positive for desmin but negative for myoglobin. Thus, the case was diagnosed as a relatively poorly differentiated botryoid rhabdomyosarcoma by the macroscopic, histopathologic, and immunohistochemical identification. This is the first report of botryoid rhabdomyosarcoma developing in the vagina of a dog.

Abstract
BACKGROUND Late renal dysfunction (LRD) is known to be one of the most important complications to affect long-term outcome after living-donor liver transplantation (LDLT). The relationship between angiotensin-converting enzyme insertion (I)/deletion (D) gene polymorphism and renal function after LDLT are still unknown. The aim of this study was to elucidate the risk factors for LRD after LDLT, focusing on ACE gene polymorphism. MATERIALS AND METHODS Among the 94 recipients who underwent adult-to-adult LDLT between March 2002 and September 2009, the total number of subjects who survived more than 1 year after LDLT and in whom angiotensin-converting enzyme genotype could be measured was 64. LRD was defined as estimated glomerular filtration rate level less than 60 mL/min/1.73 m(2) at any point after 1 year from undergoing LDLT. RESULTS LRD was found in 24 patients (37.5%). The incidence of LRD was significantly higher in D/D type than in I/I or I/D type: 85.7% (6/7) vs. 42.1% (8/19), 35.7% (10/38) (P = .010). Preoperative estimated glomerular filtration rate was significantly lower in D/D type than in I/I, I/D types, and postoperatively they were significantly lower in D/D type at 2, 3, and 4 years after LDLT. By multivariate analysis, age and hypertension were the independent risk factors for LRD. The 10-year survival rate was much lower in the recipients with LRD than in those without LRD at 66.7% versus 87.5%, respectively (P = .053). CONCLUSION In conclusion, age and hypertension were determined as significant independent risk factors for LRD after adult-to-adult LDLT, and the recipients with D/D genotype should be strictly cared for the development of LRD.

Abstract
Phen-PENMe2 has recently been proposed as a promising new molecule displaying solvent-tuned dual emission, highlighting an original and newly-described charge transfer model. The study of the photophysical behaviour of this molecule was extended to include protic solvents. The effects of polarity and hydrogen bonding lead to an even more evident dual emission associated with a large multi-emission band in some solvents like methanol, highlighting Phen-PENMe2 as a promising candidate for white light emission.

Abstract
We synthesized a new class of membrane-binding amphiphilic DNA consisting of hydrophilic phosphodiester-linked DNA and hydrophobic octyl phosphotriester-linked DNA. The amphiphilic DNA binds to the lipid membrane by inserting the hydrophobic region, which is facilitated by the presence of the complementary DNA strand.

Abstract
IgG4-related systemic disease (IgG4-RSD) is an emerging clinical entity about which much remains to be elucidated, in terms of its aetiology, pathogenesis, diagnosis, treatment and outcome. Autoimmune pancreatitis (AIP) and Mikulicz disease (MD) are the two major, well-studied constituents of IgG4-RSD. AIP and MD have common characteristics of forming tumour-mimicking lesions that consist of lymphoplasmacytic infiltrates and fibrosclerosis with numerous immunoglobulin G4 (IgG4)-positive plasma cells, as well as various multi-organ manifestations of IgG4-RSD. 2-[(18)F]-fluoro-2-deoxy-d-glucose positron-emission tomography/ computed tomography (FDG PET/CT) enables the acquisition of whole-body images and provides functional information about disease activity; as such it has a valuable role in staging extent of disease, guiding biopsy, and monitoring response to treatment. However, FDG PET/CT is likely to be only one component of the management strategy, and clinical, laboratory, imaging and histological findings are crucial in the overall diagnosis of the condition. At present FDG PET/CT does not have a well-established role in the assessment of patients with IgG4-RSD and future prospective studies are required to define the cost-effectiveness and clinical impact in this patient group more accurately.

Abstract
BACKGROUND AND OBJECT An antiulcer agent, ecabet sodium, is active against Helicobacter pylori. The aim of the present study was to clinically examine whether eradication therapy, which includes ecabet sodium, is effective in eradication of H. pylori after failure of first-line therapy. METHODS Patients with peptic ulcer who failed with first-line triple eradication therapy containing clarithromycin received quadruple therapy with omeprazole (20 mg, twice daily), amoxicillin (750 mg, twice daily), metronidazole (500 mg, twice daily) and ecabet sodium (1000 mg, twice daily) for 14 days. Eradication of H. pylori was judged by 13C-urea breath test 8 weeks later. RESULTS Fifty-two patients (36 men and 16 women) were included. Their mean age was 51.4 years (range 28-73). One patient dropped out because of diarrhoea. The eradication rate was 98.0% (50/51) according to the per-protocol analysis and 96.2% (50/52) according to the intention-to-treat analysis. Side effects occurred in seven patients, but none were serious. CONCLUSIONS Quadruple therapy including ecabet sodium is useful as second-line eradication treatment for H. pylori.

Abstract
A 52-year-old woman was admitted to our hospital for treatment of nephrotic syndrome. Funduscopic findings showed fundal hemorrhage and soft exudates, and serologic analysis showed a monoclonal serum component that was identified as Bence Jones protein-k type. A bone marrow biopsy showed diffuse proliferation of atypical plasma cells, while a renal biopsy showed diffuse and nodular mesangial proliferation. Immunohistochemical staining confirmed the presence of k chains along the glomerular basement membrane and in mesangial areas. The patient was diagnosed as multiple myeloma (Bence Jones k type) with light chain deposition disease (LCDD). After high-dose melphalan and autologous peripheral blood stem cell transplantation (PBSCT), the multiple myeloma and nephrotic syndrome were in complete remission; her renal function was improved, but a renal biopsy performed 6 months after PBSCT showed the persistence of diffuse and nodular lesions. By contrast, a renal biopsy performed 3 years later showed complete resolution of the diffuse and nodular mesangial proliferation.

Abstract
BACKGROUND Postprandial hyperlipidaemia is known to be a high-risk factor for atherosclerotic disease because of rapid and lasting accumulations of triglyceride-rich lipoproteins and remnants. The Niemann-Pick C1-Like 1 (NPC1L1) protein acts as an intestinal cholesterol transporter and ezetimibe, which inhibits NPC1L1, has been used in patients with hypercholesterolaemia. We investigated effects of ezetimibe on fasting lipid and lipoprotein profiles and postprandial hyperlipidaemia in patients with type IIb hyperlipidaemia. MATERIALS AND METHODS Ezetimibe 10 mg per day was administered in ten patients with type IIb hyperlipidaemia for 2 months, and lipid and lipoprotein profiles were examined during fasting and after an oral fat loading (OFL) test. RESULTS In the fasting state, ezetimibe significantly decreased not only total cholesterol, low density lipoprotein (LDL)-cholesterol and apolipoproteinB-100 (apoB-100) levels but triglycerides (TG), apoB-48 and remnant lipoprotein cholesterol (RemL-C) levels. High performance liquid chromatography analysis showed that ezetimibe decreased cholesterol and TG levels in the very low density lipoprotein (VLDL) and LDL size ranges as well as apoB-100 levels, suggesting a decrease in numbers of VLDL and LDL particles. After OFL, ezetimibe decreased the area under the curve for TG, apoB-48 and RemL-C. Ezetimibe decreased postprandial elevations of cholesterol and TG levels in the chylomicrons (CM) size range, suggesting that the postprandial production of CM particles was suppressed by ezetimibe. CONCLUSIONS These findings suggest that ezetimibe improves fasting lipoprotein profiles and postprandial hyperlipidaemia by suppressing intestinal CM production in patients with type IIb hyperlipidaemia and such treatment may prove to be effective in reducing atherosclerosis.

Abstract
Aging readily affects immune system under the influence of environmental and/or intrinsic factors while accelerating the development of various immune disorders including autoimmune diseases. Little is known about molecular and cellular mechanisms connecting between immune senescence and development of autoimmune diseases. Here, we first show strain-specific and aging-sensitive onset of B-cell abnormality in a lupus-prone MRL/Mp.Fas(lpr) (MRL/lpr) strain of mice. This abnormality was characterized by the regression of B lymphopoiesis in the bone marrow of this strain. We next examined the association between the B-cell regression and onset of autoimmune diseases in aged (MRL/lpr x C3H/He.Fas(lpr)) F2 mice, in which pathologic phenotypes, such as glomerulonephritis, vasculitis, sialoadenitis and arthritis, variously developed. We also searched whole genome to identify genetic loci linked to the B-cell regression by using the same F2 mice. The B-cell regression manifested in the spleen of F2 mice was retrospectively evaluated by reverse transcriptase-based PCR quantification. The results demonstrated that the onset of autoimmune diseases in the F2 mice was not associated with the aging-sensitive B-cell regression. The genetic study identified a significant locus responsible for the B-cell regression in the vicinity of D5Mit233 (29 cM). This is first evidence for the presence of a genetic locus that affects B lymphopoiesis in an aging-sensitive manner.
