Abstract
BACKGROUND Rhabdomyolysis is a potentially life-threatening disease caused by melting or necrosis of skeletal muscle cells and leakage of muscle components into the bloodstream. It has been reported that the interaction of the HMG-CoA reductase inhibitor rosuvastatin with the renal anemia drug vadadustat increases the blood concentration of rosuvastatin in vitro. In this study, we report a case of suspected rhabdomyolysis caused by the drug interaction of rosuvastatin and vadadustat in clinical practice. CASE PRESENTATION A 62-year-old male with medical records of hypertension, myocardial infarction, chronic renal failure, renal anemia, dyslipidemia, and alcoholic liver disease. The patient had been diagnosed with chronic kidney disease (CKD) at the Department of Nephrology, and treated by outpatient care with renal support therapy for the past two years. On X-63 day, his prescription was rosuvastatin (10 mg/day) and a continuous erythrocyte-stimulating agent, epoetin beta pegol (genetical recombination, 100 μg). X-Day 0, blood tests revealed creatine phosphokinase (CPK) 298 U/L, serum creatinine (SCr) 5.26 mg/dL, and hemoglobin (Hb) 9.5 g/dL; thus, the prescription was changed from epoetin beta pegol 100 μg to vadadustat 300 mg/day. On X + day 80, a prescription for a diuretic (azosemide 15 mg/day) was added for swelling of the lower extremities. On X + day 105, we found CPK 16,509 U/L, SCr 6.51 mg/dL, and Hb 9.5 g/dL. The patient was diagnosed as rhabdomyolysis and hospitalized. After hospitalization, rosuvastatin and vadadustat were discontinued and we administered intravenous fluids. Thereafter, CPK and SCr values of the patient improved. On X + day 122, CPK improved to 29 U/L, SCr to 2.6 mg/dL, and Hb to 9.6 g/dL, and he was discharged on X + day 124. At discharge, rosuvastatin 2.5 mg/day was resumed. A blood test on X + day 133 showed CPK 144 U/L and SCr 4.2 mg/dL. CONCLUSION We experienced a case of rhabdomyolysis caused by drug interactions between rosuvastatin and vadadustat.

Abstract
Abstract
Study question
Is it possible to identify the optimal puncture position by image analysis where oocyte degeneration is reduced in ICSI procedure?
Summary answer
Visualizing the likelihood of unintentional membrane rupture (UMR) using image analysis can reduce oocyte degeneration and thereby generate more embryos available for treatment.
What is known already
It is known that the oocyte degeneration after both conventional-ICSI and Piezo-ICSI are often observed when UMR occurs during the puncturing process and the likelihood of UMR may depends on the location of the puncture site on the oolemma. Identifying the appropriate puncturing position may decrease the likelihood of membrane rupture and thus degeneration, however, there are no studies identifying the optimal puncture position during ICSI.
Study design, size, duration
We have developed the ICSI Position Detector (IPD), which can identify an area where rupture is likely to occur and visualize it on a video monitor. This study included 1,110 mature oocytes retrieved from 190 consenting patients. Matured oocytes were inseminated either by Conventional-ICSI (n = 437, average maternal age: 39.1±4.6 y.o.) or Piezo-ICSI (n = 673, average maternal age: 38.6±4.5 y.o.). ICSI was performed blindly, moving images were recorded and analyzed retrospectively during ICSI using IPD.
Participants/materials, setting, methods
Inseminated oocytes were subsequently divided into two groups according to IPD results, oocytes on which ICSI was performed at the position with a low chance of UMR (appropriate group), and with a high chance of UMR (non-appropriate group) by IPD. The rates of UMR, degeneration, fertilization (2PN), blastocyst formation, and good-quality blastocyst (Grade 3BB and above on day 5 by the Gardner scoring) were compared between the two groups of both conventional-ICSI and Piezo-ICSI.
Main results and the role of chance
The areas in which UMR is less likely to occur and more likely to occur are heterogeneously distributed. When ICSI was performed blindly, about half was from the non-appropriate position. In appropriate group of Piezo-ICSI, rates of UMR (4.3% vs. 17.4%, P < 0.001) and degeneration (1.0% vs. 5.7%, P < 0.001) were significantly lower than those of non-appropriate group, whereas rates of fertilization (88.0% vs. 78.4%, P < 0.01) and blastocyst formation (57.8% vs. 45.9%, P < 0.01) were significantly higher than those of non-appropriate group, respectively. The rate of good-quality blastocyst (28.8% vs. 24.9%) was in favor of appropriate group, but not significantly different. In appropriate group of Conventional-ICSI, rates of UMR (6.7% vs. 20.6%, P < 0.001) and degeneration (1.5% vs. 6.6%, P < 0.01) were significantly lower than those of non-appropriate group, whereas rate of fertilization (88.7% vs. 69.5, P < 0.001) was significantly higher than those of non-appropriate group, respectively. The rates of blastocyst formation (37.5% vs. 35.3%), good-quality blastocyst (21.3% vs. 18.7%) were all in favor of appropriate group, but not significantly different.
Limitations, reasons for caution
This is a single private fertility clinic study. Its reproducibility should be assessed in different laboratory conditions and the hands of different operators. Moreover, specific studies should be addressed on the effect of the other putative confounders under investigation (e.g. kind of ovulation trigger, patient demographics, culture environment, etc.).
Wider implications of the findings
This study demonstrated that the IPD is useful to identify the optimal puncture location site to prevent UMR on ICSI procedure, resulting in reducing UMR and degeneration of the oocytes and increasing culture results, thereby, generating more embryos available for transfer or cryopreservation.

Abstract
INTRODUCTION Acute kidney injury (AKI) is a life-threatening condition and often progresses to chronic kidney disease or may develop other organ dysfunction even after recovery. Despite the increased recognition and high prevalence of AKI worldwide, there has been no established treatment so far. The aim of this study is to investigate the renoprotective effect of KUS121, a novel valosin-containing protein (VCP) modulator, on AKI. METHODS In in vitro experiment, we evaluated cell viability and ATP levels of proximal tubular cells (PTs) with or without KUS121 under ER-stress condition. In in vivo experiment, the effects of KUS121 were examined in mice with AKI caused by ischemia-reperfusion (I/R) injury. ER-associated degradation (ERAD)-processing capacity was evaluated by quantification of ERAD substrate CD3delta-YFP. RESULTS KUS121 protected PTs from cell death under ER stress. Apoptotic response was mitigated as indicated by the suppression of CHOP expression and caspase-3 cleavage, with maintained intracellular ATP levels by KUS121 administration. KUS121 treatment suppressed the elevation of serum creatinine and NGAL levels and attenuated renal tubular damages after I/R. The expression of inflammatory cytokines in the kidney was also suppressed in the KUS121-treated group. VCP expression levels were not altered by KUS121 both in vitro and in vivo. KUS121 treatment restored ERAD-processing capacity associated with potentiation of its upstream pathway, phosphorylated IRE1a and spliced XBP1. CONCLUSIONS These findings indicate that KUS 121 can protect renal tubular cells from ER stress-induced injury, suggesting that KUS121 could be a novel and promising therapeutic compound for ischemia-associated AKI.

Abstract
The world’s population is aging, and intergenerational conflicts between older adults and young people are becoming more serious. This study focused on ageism as a cause of intergenerational conflicts and older adults’ diminished mental health status. We conducted an online survey of older Japanese participants (n = 1.096). Our results indicated that older adults who perceived more ageism directed toward them (1) had more negative attitudes toward young people and (2) had lower life satisfaction, which persisted even after controlling for variables such as old age identity and depressive tendencies. Accordingly, we suggest that ageism may reinforce intergenerational conflicts between older adults and young people and compromise older adults’ mental health status. The findings of this study can aid gerontological and psychological research aimed at reducing ageism.

Osteocrin, a bone-derived humoral factor, exerts a renoprotective role in ischemia-reperfusion injury in mice. Nephrol Dial Transplant 2021; 37:444-453. [PMID: 34610136 PMCID: PMC8875462 DOI: 10.1093/ndt/gfab286] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Indexed: 12/11/2022] Open
Abstract
Background Osteocrin (OSTN), a bone-derived humoral factor, was reported to act on heart and bone by potentiating the natriuretic peptide (NP) system. Ostn gene polymorphisms have been associated with renal function decline, but its pathophysiological role in the kidney remains unclear. Methods The role of endogenous OSTN was investigated using systemic Ostn-knockout (KO) mice. As a model for OSTN administration, liver-specific Ostn-overexpressing mice crossed with KO (KO-Tg) were generated. These mice were subjected to unilateral ischemia–reperfusion injury (IRI) and renal lesions after 21 days of insult were evaluated. A comprehensive analysis of the Wnt/β-catenin pathway was performed using a polymerase chain reaction (PCR) array. Reporter plasmid-transfected proximal tubular cells (NRK52E) were used to investigate the mechanism by which OSTN affects the pathway. Results After injury, KO mice showed marginal worsening of renal fibrosis compared with wild-type mice, with comparable renal atrophy. KO-Tg mice showed significantly ameliorated renal atrophy, fibrosis and tubular injury, together with reduced expressions of fibrosis- and inflammation-related genes. The PCR array showed that the activation of the Wnt/β-catenin pathway was attenuated in KO-Tg mice. The downstream targets Mmp7, Myc and Axin2 showed similar results. MMP7 and Wnt2 were induced in corticomedullary proximal tubules after injury, but not in KO-Tg. In NRK52E, OSTN significantly potentiated the inhibitory effects of NP on transforming growth factor β1–induced activation of the Wnt/β-catenin pathway, which was reproduced by a cyclic guanosine monophosphate analog. Conclusions Ectopic Ostn overexpression ameliorated subsequent renal injury following ischemia–reperfusion. OSTN could represent possible renoprotection in acute to chronic kidney disease transition, thus serving as a potential therapeutic strategy.

Suppressed ER-associated degradation by intraglomerular cross talk between mesangial cells and podocytes causes podocyte injury in diabetic kidney disease. FASEB J 2020; 34:15577-15590. [PMID: 32996639 DOI: 10.1096/fj.202000078rr] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2020] [Revised: 09/14/2020] [Accepted: 09/21/2020] [Indexed: 12/21/2022]
Abstract
Mesangial lesions and podocyte injury are essential manifestations of the progression of diabetic kidney disease (DKD). Although cross-communication between mesangial cells (MCs) and podocytes has recently been suggested by the results of single-nucleus RNA sequencing analyses, the molecular mechanisms and role in disease progression remain elusive. Our cDNA microarray data of diabetic mouse glomeruli suggested the involvement of endoplasmic reticulum (ER) stress in DKD pathophysiology. In vitro experiments revealed the suppression of the ER-associated degradation (ERAD) pathway and induction of apoptosis in podocytes that were stimulated with the supernatant of MCs cultured in high glucose conditions. In diabetic mice, ERAD inhibition resulted in exacerbated albuminuria, increased apoptosis in podocytes, and reduced nephrin expression associated with the downregulation of ERAD-related biomolecules. Flow cytometry analysis of podocytes isolated from MafB (a transcription factor known to be expressed in macrophages and podocytes)-GFP knock-in mice revealed that ERAD inhibition resulted in decreased nephrin phosphorylation. These findings suggest that an intraglomerular cross talk between MCs and podocytes can inhibit physiological ERAD processes and suppress the phosphorylation of nephrin in podocytes, which thereby lead to podocyte injury under diabetic conditions. Therapeutic intervention of the ERAD pathway through the cross talk between these cells is potentially a novel strategy for DKD.

Abstract
AIM Evidence is lacking on the best standard method for forced diuresis to prevent cisplatin-induced nephrotoxicity. We compared the cisplatin-induced nephrotoxicity prevention effect of furosemide or mannitol in patients with advanced non-small cell lung cancer. METHODS Patients with advanced non-small cell lung cancer suitable to receive cisplatin-containing regimen were randomly assigned to receive furosemide or mannitol with appropriate hydration. The primary endpoint was the proportion of ≥ grade 1 serum creatinine elevation in the first cycle. RESULTS The trial was terminated early with 44 (22 per arm) of the planned 66 patients because of slow accrual. Patients' characteristics were well balanced with median baseline creatinine clearance of 98.0 and 95.1 mL/min in the furosemide and mannitol arms, respectively. In the first cycle, two (9%) and four (18%) patients developed grade 1 creatinine elevation (P = .66), respectively, despite no ≥ grade 2 toxicity. The median times to develop the worst creatinine score were 10 and 8 days, respectively. For all cycles, median times to recover to grade 0 were 56 and 20 days, respectively. The furosemide arm was characterized by relatively high urine output after cisplatin administration (900 vs 550 mL/h), low frequency of unplanned additional hydration (14% vs 32%), and high incidence of hyponatremia (18% and 5%) compared with the mannitol arm. Both arms showed similar progression-free survival and overall survival. CONCLUSION The preventive effect of the two forced diuretics on cisplatin-induced nephrotoxicity was not significantly different. However, the two diuretics have some distinct types of clinical presentations.

Ablation of Myeloid Cell MRP8 Ameliorates Nephrotoxic Serum-induced Glomerulonephritis by Affecting Macrophage Characterization through Intraglomerular Crosstalk. Sci Rep 2020; 10:3056.

Abstract
Toll-like receptor 4 (TLR4) and one of its endogenous ligands myeloid-related protein 8 (MRP8 or S100A8), especially expressed in macrophages, play an important role in diabetic nephropathy and autoimmune disorders. However, detailed mechanisms and consequence of MRP8 expression remain unknown, partly due to embryonic lethality of MRP8 knockout mice. In this study, Myeloid lineage cell-specific MRP8 knockout mice were generated, and nephrotoxic serum-induced glomerulonephritis was developed. Mice with conditional ablation of MRP8 gene in myeloid cells exhibited less severe histological damage, proteinuria and inflammatory changes compared to control mice. Mechanism of MRP8 upregulation was investigated using cultured cells. Co-culture of macrophages with mesangial cells or mesangial cell-conditioned media, but not with proximal tubules, markedly upregulated MRP8 gene expression and inflammatory M1 phenotype in macrophages, which was attenuated in MRP8-deleted bone marrow-derived macrophages. Effects of MRP8 deletion was further studied in the context of macrophage-inducible C-type lectin (Mincle), which is critically involved in maintenance of M1 phenotype of macrophages. MRP8 ablation in myeloid cells suppressed the induction of Mincle expression on macrophages in glomerulonephritis. Thus, we propose that intraglomerular crosstalk between mesangial cells and macrophages plays a role in inflammatory changes in glomerulonephritis, and MRP8-dependent Mincle expression in macrophage may be involved in the process.

Abstract
Abstract
Background
Critical limb ischemia (CLI) is the most progressed manifestation of peripheral artery disease. Although patients with CLI commonly complicate with severely calcified lesions in infrapopliteal lesions, the prognostic impact of infrapopliteal arterial calcification on wound healing in patients with CLI has not been systematically studied.
Purpose
The aim of current study was to elucidate the prognostic impact of infrapopliteal arterial calcification on wound healing in CLI undergoing endovascular therapy (EVT).
Methods
This study enrolled 639 CLI patients with tissue loss (age 74±10 years, male 62%, diabetes 69%, hemodialysis 57%, Rutherford class 5 77%, class 6 23%) primarily treated with EVT for the infrapopliteal lesions between April 2010 and December 2015. Arterial calcification was assessed by high intensity fluoroscopy and classified into 3 groups as follows; 1) none, 2) unilateral and 3) bilateral calcification. The primary outcome measure was complete wound healing. The predictors of the outcome were evaluated by Cox proportional hazards regression analysis.
Results
During a mean follow-up period of 22±19 months, 1-year wound healing rate were 59.0%. In Kaplan-Meier analysis, 1-year wound healing rate was worse in patients with bilateral calcification than in those with unilateral or none calcification (Figure, 46.2% versus 55.1% versus 67.8%, P<0.001). After multivariate analysis, the predictors of wound healing were non-ambulatory status (hazard ratio (HR) 0.67 [95% confidential interval (CI) 0.53–0.85], P=0.001) and bilateral calcification (HR 0.75 [95% CI 0.47–0.98], versus none or unilateral calcification, P=0.036).

Conclusion
Infrapopliteal Arterial calcification as well as non-ambulatory status was associated with wound healing in patients with CLI.

Abstract
Abstract
Background
Recent randomized, placebo-controlled trial in patients with type 2 diabetes demonstrated that the sodium-glucose cotransporter 2 inhibitors reduced mortality, cardiovascular events and hospitalization for heart failure. However, those trials were not specialized design to investigate the effect of sodium-glucose cotransporter 2 inhibitors in patients with heart failure, in particular with heart failure with preserved ejection fraction.
Purpose
The aim of this study was to evaluate the drug efficacy of luseogliflozin, a sodium-glucose cotransporter 2 inhibitor, compared with voglibose, an alpha-glucosidase inhibitor, using brain natriuretic peptide (BNP) in type 2 diabetes patients with heart failure with preserved ejection fraction.
Methods
This study was a prospective, multicenter, open-label, randomized-controlled trial, comparing luseogliflozin 2.5 mg once daily or voglibose 0.2 mg three times daily in patients with type 2 diabetes suffering from heart failure with preserved ejection fraction (left ventricular ejection fraction >45% and BNP ≥35 pg/ml2) in a 1:1 randomization fashion. Randomization was undertaken using a computer-generated random sequence web response system. The primary outcome was the difference from baseline in BNP after 12 weeks of treatment between two drugs. The key secondary outcomes were the change from baseline in left ventricular ejection fraction and E/e' in echocardiographic parameters, body weight, glycohemoglobin level after 12 weeks of treatment. The safety outcomes included the incidence of major adverse cardiovascular events, hypoglycemic adverse events, and urinary tract infection.
Results
Between December 2015 and September 2018, 173 patients from 16 hospitals and clinics have been included in this study. Of those, 83 patients were assigned to receive luseogliflozin and 82 to receive voglibose. There was no significant difference in the reduction in the BNP concentration after 12 weeks from baseline between the two groups; the ratio of the average values at week 12 to the baseline value was 0.91 in the luseoglifllzin group as compared with 0.98 in the voglibose group (percent change, −9.0% vs. −1.9%, ratio of change with luseogliflozin vs. voglibose, 0.93; 95% confidence interval, 0.78 to 1.10; p=0.26). The key secondary outcomes including left ventricular ejection fraction, E/e', body weight, glycohemoglobin level and the safety outcomes did not differ significantly between the two groups.
Conclusions
In type 2 diabetes patients with heart failure with preserved ejection fraction, the administration of luseogliflozin did not lead to a significant reduction in the BNP concentration than that of voglibose. Left ventricular ejection fraction, E/e', body weight and glycohemoglobin level after 12 weeks of treatment, comparing with at baseline did not differ significantly between the two groups.

Abstract
Abstract
Background
Biodegradable polymer drug-eluting stent (BP-DES) has been developed to improve clinical outcomes after percutaneous coronary intervention (PCI) for patients presenting coronary artery disease (CAD). Although BP-DES showed non-inferior safety and efficacy to durable polymer DES (DP-DES) in several randomized clinical trials, hemodialysis (HD) patients, who have been well known as high risk population for adverse events, were excluded in the most of trials. Therefore, there are limited data comparing the clinical outcomes between BP-DES and DP-DES in HD patients with CAD after PCI.
Purpose
The purpose of this study was to investigate clinical outcomes in HD patients after BP-DES implantation compared with those after DP-DES implantation.
Methods
We retrospectively analyzed 234 HD patients (male 74%, mean age 71±10 years) undergoing PCI for 404 lesions with 472 DESs (71 patients for 138 lesions with 170 BP-DESs [91 Ultimaster and 79 Synergy] and 163 HD patients for 266 lesions with 302 DP-DESs [219 Xience, 53 Promus and 30 Resolute]) from 2011 to 2017. Two-year clinical outcomes were compared between BP-DES group and DP-DES group. The primary outcome measure was the incidence of target lesion revascularization (TLR), while the secondary outcome measures were the occurrence of cardiac death (CD), stent thrombosis (ST), myocardial infraction (MI), target vessel revascularization (TVR), non-TVR and major adverse cardiac event (MACE) defined as a composite of CD, MI, and TVR. Outcome measures were estimated by the Kaplan-Meier method and the differences between BP-DES group and DP-DES group were assessed by the log-rank test. We also conducted Cox's proportional hazard model to identify predictors for TLR occurrence.
Results
Baseline patient and lesion characteristics were similar between the two groups. The two-year incidence of TLR was not significantly different between BP-DES group and DP-DES group (14.1% vs. 22.2%, p=0.391). The two-year incidences of CD (17.3% vs. 17.5%, p=0.381), ST (0% vs. 3.9%, p=0.133), MI (4.2% vs. 5.8%, p=0.965), TVR (21.3% vs. 27.5%, p=0.586), non-TVR (26.1% vs. 31.3%, p=0.439) and MACE (41.1% vs. 42.6%, p=0.526) were also not different between the two groups. After multivariate analysis, diabetes mellitus (hazard ratio 1.97; 95% confidence interval 1.03–3.78, p=0.004) was independently associated with TLR occurrence in HD patients.
Two-year clinical outcomes of HD patient
Conclusions
At two-year follow-up after PCI, BP-DES had comparable safety and efficacy profiles to DP-DES in HD patients presenting CAD.

Abstract
Pulmonary pleomorphic carcinoma (PPC) is a rare very aggressive subtype of non-small cell lung cancer. We herein report a case of PPC that showed a rapid response to nivolumab. The patient, whose multiple tumors had progressed very aggressively, was treated with nivolumab, an anti-programmed cell death-1 (PD-1) antibody. The tumors dramatically shrank after one cycle of nivolumab. The tumors were positive for programmed cell death ligand 1 (PD-L1). An immunohistochemical analysis revealed numerous PD-1+, CD68+ and CD206+ macrophages. This PD-1 antibody may be a good treatment option, especially in tumors that express PD-L1 and which show PD-1+ macrophage infiltration.

Abstract
We herein report a case of pulmonary hyalinizing granuloma (PHG), which is a rare pulmonary mass. A 69-year-old man with no symptoms presented to our hospital because of the appearance of an abnormal shadow on chest X-ray. Computed tomography revealed a right middle-lobe mass with spicula and infiltration into the upper lobe. Since a bronchofiberscopic examination showed no malignant cells in the specimen, the patient underwent thoracoscopic surgery, which revealed PHG. Spiculation and interlobar infiltration, which comprise the characteristic features of primary lung cancer, are uncommon presentations of this rare entity.

Abstract
PURPOSE To investigate the aqueous and vitreous penetration of levofloxacin, the drug was administered topically and/or orally to patients undergoing vitrectomy. METHODS Thirty-six patients undergoing initial vitrectomy with phacoemulsification and aspiration (PEA) were enrolled, and were divided randomly into three groups. Group 1 was treated with topical application of levofloxacin (three times on the day before surgery and seven times on the day of surgery), Group 2 received oral administration of levofloxacin (200 mg twice on the day before surgery and 200 mg at 3 hours before surgery), and Group 3 received both topical and oral levofloxacin according to the above schedules. The concentration of levofloxacin was measured in aqueous humor and vitreous fluid samples obtained during surgery. RESULTS In Groups 1, 2, and 3, the mean levofloxacin concentration in aqueous humor was 0.765+/-0.624 micro g/mL, 1.279+/-0.440 micro g/mL, and 1.823+/-0.490 micro g/mL, respectively, while the mean levofloxacin concentration in vitreous fluid was <0.02 micro g/mL, 1.455+/-0.445 micro g/mL, and 1.369+/-0.530 micro g/mL, respectively. CONCLUSIONS Oral administration of levofloxacin at a dose of 400 mg/day was sufficient for the prophylaxis of ocular infections, because the drug concentrations in both aqueous humor and vitreous fluid were higher than the MIC90 values for major ocular pathogens. Topical application of levofloxacin achieved adequate drug levels in aqueous humor, but not in vitreous fluid, while combined topical and oral administration had an additive effect on the drug concentration in aqueous humor.

Abstract
PURPOSE To evaluate the results and complications of combined pars plana vitrectomy (PPV), phacoemulsification and aspiration (PEA), and intraocular lens (IOL) implantation. METHODS A total of 117 eyes from 114 patients who had undergone PPV combined with PEA and IOL implantation were retrospectively analyzed. Combined surgery was performed for a wide variety of vitreoretinal diseases. Intraoperative and postoperative complications were also reviewed. RESULTS The postoperative BCVA improved by 2 lines or more in 85 eyes (72.6%). Intraoperative complications consisted of retinal tears in 14 eyes (12.0%) and posterior capsular rupture in 2 eyes (1.7%). Iatrogenic retinal tears occurred more frequently in eyes with a macular hole than in eyes with any other disease (p=0.005, chi-square test). Postoperative complications consisted of posterior capsule opacification (PCO) (21 eyes), transient IOP elevation (29 eyes), vitreous hemorrhage (6 eyes), anterior chamber fibrin exudation (11 eyes), posterior iris synechia (8 eyes), neovascular glaucoma (1 eye), and recurrent retinal detachment (RD) (2 eyes). Fibrin exudation occurred more frequently in eyes with proliferative diabetic retinopathy (PDR) and RD than in eyes with any other disease (p=0.03, chi-square test). PCO occurred more frequently in eyes with PDR than in eyes with any other disease (p=0.03, chi-square test). CONCLUSIONS The present study suggests that a high success rate can be achieved when recently improved PPV techniques are combined wi th PEA and IOL implantation. The complications that were observed following this combined treatment varied with respect to the vitreoretinal disease present prior to surgery.

Abstract
We report six patients with closed flexor tendon rupture affecting the little finger, occurring secondarily to non-union of the hook of the hamate bone. The ununited fragments were separated from the basal part of the hook by more than 1 mm. The fragments were also rounded and showed marginal sclerosis. Non-union was located in the middle part of the hook in three patients, the tip in two, and the base in one. At operation, the fragments were removed in all patients. Five patients were treated by free tendon grafts using three palmaris and two plantaris grafts and one underwent tendon transfer. Postoperative total range of active motion of the little finger averaged 218° (range 185–265°). All patients returned to their original employment. This series would suggest that flexor tendon rupture can occur after fracture of the hook of the hamate bone, even when the ununited fragment is small and/or rounded.

Abstract
Although it has been reported that oxytocin stimulates lipolysis in adipocytes, changes in the expression of oxytocin receptor (OTR) mRNA in adipogenesis are still unknown. The present study aimed to investigate the expression of OTR mRNA during adipocyte differentiation and fat accumulation in adipocytes. OTR mRNA was highly expressed in adipocytes prepared from mouse adipose tissues compared to stromal-vascular cells. OTR mRNA expression was increased during the adipocyte differentiation of 3T3-L1 cells. OTR expression levels were higher in subcutaneous and epididymal adipose tissues of 14-week-old male mice compared to 7-week-old male mice. Levels of OTR mRNA expression were higher in adipose tissues at four different sites of mice fed a high-fat diet than in those of mice fed a normal diet. The OTR expression level was also increased by refeeding for 4 h after fasting for 16 h. Oxytocin significantly induced lipolysis in 3T3-L1 adipocytes. In conclusion, a new regulatory mechanism is demonstrated for oxytocin to control the differentiation and fat accumulation in adipocytes via activation of OTR as a part of the hypothalamic-pituitary-adipose axis.

Abstract
Pemetrexedis a key drug in the first and second -line therapy for non-small-cell lung cancer. It exhibits an increased area under the plasma drug concentration-time curve, and it has a prolonged half -life when administered to patients with reduced renal function, resulting in a high frequency of neutropenia. Accordingly, pemetrexed is administered to these patients with caution. Herein, we retrospectively investigated the background characteristics of patients with a creatinine clearance rate (Ccr) of<45 mL/min, who experienced severe adverse events due to pemetrexed. Thirty-eight patients with a Ccr of <45 mL/min were administered pemetrexed. Of these patients, 13 (34%) developed severe adverse events (≥Grade 3) such as neutropenia, thrombocytopenia, and nausea. Multiple logistic regression analysis revealed that a Ccr of <30 mL/min (p= 0.033) and the concomitant use of non-steroidal anti-inflammatory drugs (p=0.012) were significant risk factors for adverse events. Therefore, whenever possible, pemetrexed administration should be avoided in patients with a Ccr of <30 mL/ min and in those receiving concomitant non-steroidal anti-inflammatory drugs.

Abstract
Location and number of liver metastasis of gastrointestinal tumors were detected preoperatively and intraoperatively. The distribution of the liver segment(s) occupied by metastatic tumors varied significantly (p<0.05). Significantly more frequent distributions were demonstrated in the lateral segment with gastric cancer (p<0.05), in the posterior segment with left colic cancer (p<0.001), in the medial segment with rectal cancer (p<0.01), in the anterior segment with bile duct cancer (p<0.05) and the whole of the liver with pancreatic cancer (p<0.05). Significantly less frequent distribution was demonstrated in the posterior segment with gastric cancer (p<0.01). When the liver was divided into the right and the left halves, the distribution of each half of the liver occupied by metastatic tumors varied significantly (p<0.05). Liver metastases of whole colic cancer were significantly more frequent in the right half of the liver (p<0.05). The results suggest that the tumor distribution in liver metastases of gastrointestinal tumors differ depending upon the primary tumors, basically in accordance with the 'streamline' phenomena.

Abstract
The establishment of liver metastasis from gastrointestinal tumor is mainly considered to be via the portal vein, but its precise mechanism is still unknown. The purpose of this study is to evaluate the significance-of 'streamline' phenomena in liver metastasis of gastrointestinal tumor by means of an experimental model. An animal model for the metastatic liver tumor was made in the Donryu rat. Five million cells of AH-66 strain, alpha-fetoprotein (AFP) producing hepatoma cells maintained as an ascites type strain, were administered via portal vein. The superior mesenteric vein (group A), the inferior mesenteric vein (group B) and the splenic vein (group C) were used as the sites of injection. In every group, serum AFP levels were elevated after administration of AH-66 cells and no significant differences were revealed between each group. In the pathological specimens of the liver taken after 7 days, many tumorous lesions were seen microscopically with islet formations, but no definitive difference was seen in each lobe. The serum AFP concentration in group A was significantly higher than that in group C. The tissue AFP concentrations of the right lobe were significantly higher than those of the left in groups A and B, but significantly lower than those of the left lobe in group C. The results indicate that the distribution and proliferation of tumor cells administered via portal vein differed depending upon the site of tumor injection in accordance with the 'streamline' phenomena.

Abstract
OBJECTIVE The aim of this study was to assess the genetic effects of the vascular endothelial growth factor (VEGF) pathway on retinopathy of prematurity (ROP). STUDY DESIGN A prospective study from a tertiary center that enrolled 204 Japanese infants (<35 weeks of gestational age (GA)) having no anomalies. ROP developed in 127, but not in 77 infants. The relative severity was defined as non-severe, moderate and severe ROP for GA, based on the staging criteria. VEGF (g.-634G>C, g.+13553C>T) and VEGF-receptor (KDR g.+4422(AC)11 to 14, Flt-1 c.+6724(TG)13 to 23) gene polymorphisms and clinical variables were assessed by uni/multivariate analyses. RESULT The frequency of polymorphisms did not differ between ROP and non-ROP patients. The TT genotype of g.+13553 showed a higher odds ratio for non-severe ROP than CC genotype (P=0.006). Multivariate analyses indicated that low birth weight, blood transfusion and respiratory distress syndrome, but not polymorphisms, were the risk factors of advanced ROP (≥ stage 3). CONCLUSION A genotype of the VEGF pathway weakly affects the severity of ROP compared with other clinical factors.

Abstract
Complete nucleotide sequences were determined for subtype B avian metapneumovirus (aMPV), the attenuated vaccine strain VCO3/50 and its parental pathogenic strain VCO3/60616. The genomes of both strains comprised 13,508 nucleotides (nt), with a 42-nt leader at the 3'-end and a 46-nt trailer at the 5'-end. The genome contains eight genes in the order 3'-N-P-M-F-M2-SH-G-L-5', which is the same order shown in the other metapneumoviruses. The genes are flanked on either side by conserved transcriptional start and stop signals and have intergenic sequences varying in length from 1 to 88 nt. Comparison of nt and predicted amino acid (aa) sequences of VCO3/60616 with those of other metapneumoviruses revealed higher homology with aMPV subtype A virus than with other metapneumoviruses. A total of 18 nt and 10 deduced aa differences were seen between the strains, and one or a combination of several differences could be associated with attenuation of VCO3/50.
