Abstract
Intramural pregnancy is a rare form of ectopic pregnancy, and the optimal treatment remains uncertain. We describe a 33-year-old woman (gravida 2, para 0) who visited our hospital with suspected ectopic pregnancy. The patient was asymptomatic and hemodynamically stable. Transvaginal ultrasonography revealed pregnancy at 6 weeks of gestation and a gestational sac and fetal heartbeat in the anterior muscular layer of the uterus, away from the endometrium. The fetal sac measured 26 mm. The serum human chorionic gonadotropin (hCG) level had increased to 27 655 mIU/mL. Accordingly, the patient was diagnosed with an intramural ectopic pregnancy and underwent total laparoscopic wedge resection using intraoperative ultrasonography. The postoperative course was uneventful, and she was discharged after 4 days. Her serum hCG level normalized at 26 days postoperatively. This case indicates that intraoperative laparoscopic ultrasonography seems viable for treating intramural pregnancies.

Abstract
We investigated the effectiveness of simulation-based education in Focused Assessment with Sonography for Trauma (FAST) to increase the number of Emergency Medical Technicians (EMTs) capable of performing ultrasound examinations in vehicles under the guidance of a physician. Twenty-eight paramedics watched a 14-min video on the features of the ultrasound system, its use, and the scanning method for each part of the body. Each participant performed four FAST examinations using a portable ultrasound device, and the task performance was rated using the Task Specific Checklist (TSC) and Global Rating Scale (GRS). The time required for visualizing each examination site and each FAST was assessed. The mean time required for the first and fourth FAST was 144.6 ± 52.4 s and 90.5 ± 31.0 s, respectively. The time required for each test significantly decreased with repeated testing (p < 0.001). The time to complete FAST was significantly shortened for the pericardial cavity (33.4 ± 23.1/15.3 ± 10.6 s, p < 0.01), right thoracic cavity (25.2 ± 11.8/12.1 ± 8.3 s, p < 0.01), Morrison fossa (19.1 ± 10.8/10.8 ± 6.3 s, p < 0.05), and left thoracic cavity (19.0 ± 8.3/15.6 ± 8.3 s, p < 0.05). TSC and GRS scores were elevated, and all EMTs could obtain valid images. The combination of a brief video lecture and hands-on training significantly reduced the time required for FAST performance. Moreover, repeated practice enabled the EMTs to efficiently obtain accurate and clinically useful images.

Abstract
OBJECTIVE To investigate the incidence and risk factors of small-for-gestational age (SGA) short stature at 2 and 3 years of age in SGA offspring born to women with hypertensive disorders of pregnancy (HDP). METHODS We examined 226 women with HDP whose respective SGA offspring were delivered. RESULTS Eighty offspring (41.2%) were diagnosed with SGA short stature. The prematurity before 32 weeks of gestation was the most significant factor for catch-up growth failure. CONCLUSION In SGA offspring born to women with HDP, SGA short stature incidence was high, and the risk factor was prematurity before 32 weeks of gestation.

Abstract
The European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, treatment and follow-up of patients with metastatic colorectal cancer (mCRC), published in late 2022, were adapted in December 2022, according to previously established standard methodology, to produce the Pan-Asian adapted (PAGA) ESMO consensus guidelines for the management of Asian patients with mCRC. The adapted guidelines presented in this manuscript represent the consensus opinions reached by a panel of Asian experts in the treatment of patients with mCRC representing the oncological societies of China (CSCO), Indonesia (ISHMO), India (ISMPO), Japan (JSMO), Korea (KSMO), Malaysia (MOS), the Philippines (PSMO), Singapore (SSO), Taiwan (TOS) and Thailand (TSCO), co-ordinated by ESMO and the Japanese Society of Medical Oncology (JSMO). The voting was based on scientific evidence and was independent of the current treatment practices, drug access restrictions and reimbursement decisions in the different Asian countries. The latter are discussed separately in the manuscript. The aim is to provide guidance for the optimisation and harmonisation of the management of patients with mCRC across the different countries of Asia, drawing on the evidence provided by both Western and Asian trials, whilst respecting the differences in screening practices, molecular profiling and age and stage at presentation, coupled with a disparity in the drug approvals and reimbursement strategies, between the different countries.

Abstract
INTRODUCTION Preeclampsia (PE) pathogenesis is explained by the two-stage disorder theory. However, mechanisms underlying hypertension and proteinuria in PE remain unclear. The role of (pro)renin receptor (PRR) in PE pathology has received special attention. We examined endothelin-1 (ET-1) production via placental PRR in a PE mouse model. METHODS At 14.5 day-post-coitum (DPC), we performed a reduced uterine perfusion pressure (RUPP) operation, ligating the uterine arteriovenous vessels in female mice. We also infused these mice with a PRR inhibitor, decoy peptide in the handle region of prorenin (HRP) for mice (NH2-RIPLKKMPSV-COOH). At 18.5 DPC, blood, urine, and placenta were collected; fetus and placenta were weighed. We evaluated placental hypoxia using quantitative polymerase chain reaction (PCR), with hypoxia-inducible factor-1α (HIF-1α) as index. We also evaluated PRR, transforming growth factor-β1 (TGF-β1), and ET-1 expression in the placenta using quantitative PCR and western blotting. ET-1 concentration in blood plasma was assessed using enzyme-linked immunosorbent assay. RESULTS Blood pressure and proteinuria significantly increased, and fetal and placental weights decreased in RUPP mice. HIF-1α, PRR, TGF-β1, and ET-1 expressions considerably increased in RUPP mice placentas. ET-1 concentration in RUPP mice blood plasma was markedly increased. PRR inhibitor suppressed these changes. DISCUSSION In PE model mice that underwent RUPP treatment, placental hypoxia increased PRR and ET-1 expression suggesting a causative relationship between ET-1 and intracellular PRR signaling. RUPP treatment, when combined with HRP, reversed the effect of elevated ET-1 levels in the model. This study may help to elucidate the pathogenesis of PE considering PRR and ET-1.

Abstract
BACKGROUND We conducted comprehensive clinical and molecular characterization of claudin 18.2 expression (CLDN18.2) in advanced gastric or gastroesophageal junction cancer (GC/GEJC). PATIENTS AND METHODS Patients with advanced GC/GEJC who received systemic chemotherapy from October 2015 to December 2019 with available tumor specimens were analyzed. We evaluated clinicopathological features of CLDN18.2 expression with four molecular subtypes: mismatch repair deficient, Epstein-Barr virus-positive, human epidermal growth factor receptor 2-positive, and others. In addition, programmed death-ligand 1 (PD-L1) combined positive score (CPS), genomic alterations, and the expression of immune cell markers were assessed. Clinical outcomes of standard first- or second-line chemotherapy and subsequent anti-programmed cell death protein 1 (anti-PD-1) therapy were also investigated according to CLDN18.2 expression. RESULTS Among 408 patients, CLDN18.2-positive (moderate-to-strong expression in ≥75%) was identified in 98 patients (24.0%) with almost equal distribution in the four molecular subtypes or CPS subgroups. CLDN18.2-positive was associated with Borrmann type 4, KRAS amplification, low CD16, and high CD68 expression. Overall survival with first-line chemotherapy was not significantly different between CLDN18.2-positive and -negative groups [median 18.4 versus 20.1 months; hazard ratio 1.26 (95% confidence interval 0.89-1.78); P = 0.191] regardless of stratification by PD-L1 CPS ≥5. Progression-free survival and objective response rates of first- and second-line chemotherapy, and anti-PD-1 therapy also showed no significant differences according to CLDN18.2 status. CONCLUSIONS CLDN18.2 expression in advanced GC/GEJC was associated with some clinical and molecular features but had no impact on treatment outcomes with chemotherapy or checkpoint inhibition. CLDN18.2-positive also had no impact on overall survival. This information could be useful to interpret the results from currently ongoing clinical trials of CLDN18.2-targeted therapies for advanced GC/GEJC and to consider a treatment strategy for CLDN18.2-positive GC/GEJC.

Abstract
"Welcome to OBGYN World!" A novel recruitment event for medical students organized by the Japan Society of Obstetrics and Gynecology. Since 2012, the number of doctors in Japan who specialize in obstetrics and gynecology has shown a decreasing trend. To increase the number of doctors majoring in obstetrics and gynecology, the Japanese Trainees in Obstetrics and Gynecology subcommittee developed a new recruitment event called Welcome to OBGYN World! (WOW!); the aim of this event was to focus on lower grades of medical students. The present report describes the content of WOW! and the results of a post-event questionnaire administered to participating students and tutors. WOW! was held online in order to avoid the risk of Coronavirus Disease 2019 infection for participants. Sixty of the 82 medical schools nationwide (73.2%) participated in this event. Overall, there were 285 participating students, ranging from first to fourth grade in medical school, and 106 tutors were involved to teach material at the event. In the post-event questionnaire survey, 97.6% (248/254) and 100% of the participants stated they now had a high degree of interest in obstetrics and gynecology and found the specialty attractive, respectively. Furthermore, 93.6% (90/94) of the tutors stated that WOW! had helped recruitment activities in their universities. Based on this outcome, members of the Japanese Trainees of Obstetrics and Gynecology subcommittee will now try to increase the number of doctors specializing in obstetrics and gynecology by holding WOW! annually.

Abstract
Pyomyoma is a rare condition that causes fever and abdominal pain associated with pregnancy, especially in the postpartum period. An appropriate diagnosis and early medical intervention are required to prevent serious complications. A 38-year-old primigravida with uterine fibroids had fever from the 11th day after cesarean section. The fever did not resolve despite repeated daily administration of broad-spectrum β-lactam antibiotics for 2 weeks. Although the physical examination did not show any lower abdominal pain, a pelvic magnetic resonance scan revealed degenerative fibroids, and myomectomy was performed. Yellow-greenish odorless pus inside the uterus was detected, and Mycoplasma hominis was detected in the pus culture. Mycoplasma species are resistant to broad-spectrum penicillin antibiotics and can cause pyomyoma. Pyomyomas may not cause uterine tenderness, and the causative organism may be difficult to identify; therefore, additional imaging studies should be considered.

Abstract
Background The incidence of severe uterine prolapse during childbirth is approximately 0.01%. Moreover, to the best of our knowledge, no reports detail the healing process of the cervix during uterine involution. This report describes successful vaginal delivery and the healing process of postpartum uterine prolapse and cervical tears in a patient with severe uterine prolapse. Case presentation A patient in her 40s (gravida 3, para 1, abortus 1) with severe uterine prolapse successfully delivered a live female baby weighing 3190 g at 38 + 5 weeks of gestation by assisted vaginal delivery. Uterine prolapse had improved to approximately 2° by 2 months postoperatively. On postpartum day 4, during the healing process of cervical laceration, the thread loosened in a single layer of continuous sutures due to uterine involution, and poor wound healing was observed. The wound was subsequently re-sutured with a two-layer single ligation suture (Gambee suture + vertical mattress suture). However, on postpartum day 11, a large thread ball was hindering the healing of the muscle layer, which improved with re-suturing. Conclusion Although vaginal delivery in a patient with severe uterine prolapse is possible in some cases, the cervix should be sutured, while considering cervical involution after delivery. Pregnancies with complete uterine prolapse are exceedingly rare. When suturing the uterus, involution after delivery should be considered. This is the first report on the healing process of cervical canal lacerations.

Abstract
NIPT is non-definitive testing to estimate the possibility that fetuses have trisomy 21, trisomy 18, or trisomy 13. However, in NIPT-positive and indeterminate cases, rare chromosomal disease may become apparent, requiring advanced genetic considerations and counseling skills. We experienced two such cases, a trisomy 21 mosaicism case triggered by NIPT-positive status and 18q deletion syndrome triggered by NIPT-indeterminate status. These cases have two clinical implications for NIPT. First, it was revealed that trisomy mosaicism might be found in NIPT-positive cases that have lower Z-Scores than those inferred from the fraction of fetal cfDNA in the case of standard trisomy. Second, it is possible that microdeletion syndrome could be the reason for an indeterminate NIPT result. Today's genetic counseling requires more expertise in ethics and communication as well as genetic science because NIPT can lead to totally unexpected results.

Abstract
Extravillous trophoblast (EVT) invasion is important for embryo implantation, placental development, and successful remodeling of the uterine spiral artery. Endocrine gland derived-vascular endothelial growth factor (EG-VEGF) and matrix metalloproteinases (MMPs) are implicated in EVT invasion; however, the high con-centrations found in pregnancy pathologies have not been investigated in non-tumor trophoblasts. The roles of EG-VEGF, prokineticin receptors (PROKR1/2), MMP-2, and MMP-9 in EVT invasion during spiral artery remodeling were evaluated using human EVT from HTR-8/SVneo cell lines. The expression of MMP-2, MMP-9, and mitogen-activated protein kinase (MAPK), and Akt pathways in HTR-8/SVneo cells treated with recom-binant EG-VEGF alongside anti-PROKR1 and/or anti-PROKR2 antibodies was evaluated using quantitative reverse transcription-PCR and western blotting. Wound-healing and cell invasion assays were performed to assess the migration and invasion of these treated cells. Interestingly, 20 nM EG-VEGF activated ERK1/2 sig-naling and upregulated MMP-2 and MMP-9. This effect was suppressed by anti-PROKR2 antibody via ERK1/2 downregulation. Anti-PROKR2 antibody inhibited the migration and invasion of EG-VEGF-stimulated HTR-8/SVneo cells. Elevated concentrations of EG-VEGF enhance EVT invasion in a human trophoblast cell line by upregulating MMP-2 and MMP-9 via PROKR2. These new insights into the regulation of epithelial cell invasion may help in developing therapeutic interventions for placental-related diseases during pregnancy.

Abstract
The most recent version of the European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, treatment and follow-up of localised colon cancer was published in 2020. It was decided by both the ESMO and the Japanese Society of Medical Oncology (JSMO) to convene a special virtual guidelines meeting in March 2021 to adapt the ESMO 2020 guidelines to take into account the ethnic differences associated with the treatment of localised colon cancer in Asian patients. These guidelines represent the consensus opinions reached by experts in the treatment of patients with localised colon cancer representing the oncological societies of Japan (JSMO), China (CSCO), India (ISMPO), Korea (KSMO), Malaysia (MOS), Singapore (SSO) and Taiwan (TOS). The voting was based on scientific evidence and was independent of the current treatment practices and drug availability and reimbursement situations in the different Asian countries.

Abstract
Early diagnosis and therapy are important in a cesarean scar pregnancy (CSP), which can cause uterine rupture with resultant massive bleeding. However, there are some reports of CSPs continued to term. The optimal management of CSPs remains unclear; therefore, we investigated the clinical courses of CSPs diagnosed and treated at perinatal institutions in the Chugoku and Shikoku regions of Japan. We enrolled 60 women diag-nosed with CSP at 21 institutions from January 2006 to December 2015. Of the 60 women diagnosed with CSP, 57 were treated. Pregnancy was terminated in 48 women and continued in 9. Thirteen women underwent transabdominal hysterectomy; they experienced no postoperative complications or allogeneic blood transfu-sion. Nine women received therapies such as dilation and curettage, and 26 received non-surgical therapies such as methotrexate and topical administration of potassium chloride. Among 9 women who chose to con-tinue with their CSP, 7 successfully delivered newborns, 2 had uterine ruptures in the second trimester, and all women required transabdominal hysterectomy. Diagnosis and therapy in the first trimester of pregnancy are important in the management strategy of a CSP. When continuing a CSP, the risk of uterine rupture and trans-abdominal hysterectomy must be considered.

Abstract
BACKGROUND Two-dimensional (2D) speckle tracking echography (STE) is a new diagnostic modality that allows for the assessment of myocardial deformation. The present study assessed the feasibility of fetal 2D-STE at a high frame rate and determined the reference values for left ventricular (LV)- and right ventricular (RV)- global longitudinal strain (GLS). METHODS In this prospective study, 109 fetuses with gestational ages ranging from 18 to 38 weeks underwent 2D echocardiography between August 2018 and December 2019. All recordings were performed using the Aplio i800 (CANON Medical Systems Corporation, Tochigi, Japan) and a convex probe (4 MHz) for fetuses. RESULTS Longitudinal peak systolic strain measurements were obtained in 98 of 109 healthy fetuses (90%). All ultrasound videos were recorded with a median frame rate of 172 (range, 100-274) frames/s. The LV-GLS was almost constant, regardless of the number of weeks since the second trimester (r = -0.0087, p = ns). The RV-GLS decreased significantly with gestational age (r = 0.39, p < 0.01). CONCLUSIONS STE may be useful for quantifying the systolic myocardial function in a fetus.

Abstract
A Japan Society of Clinical Oncology (JSCO)-hosted expert meeting was held in Japan on 27 October 2019, which comprised experts from the JSCO, the Japanese Society of Medical Oncology (JSMO), the European Society for Medical Oncology (ESMO), the American Society of Clinical Oncology (ASCO), and the Taiwan Oncology Society (TOS). The purpose of the meeting was to focus on what we have learnt from both microsatellite instability (MSI)/deficient mismatch repair (dMMR) biomarkers in predicting the efficacy of anti-programmed death-1 (PD-1)/programmed death ligand-1 (PD-L1) immunotherapy, and the neurotrophic tyrosine receptor kinase (NTRK) gene fusions in predicting the efficacy of inhibitors of the tropomyosin receptor kinase (TRK) proteins across a range of solid tumour types. The recent regulatory approvals of the anti-PD-1 antibody pembrolizumab and the TRK inhibitors larotrectinib and entrectinib, based on specific tumour biomarkers rather than specific tumour type, have heralded a paradigm shift in cancer treatment approaches. The purpose of the meeting was to develop international expert consensus recommendations on the use of such tumour-agnostic treatments in patients with solid tumours. The aim was to generate a reference document for clinical practice, for pharmaceutical companies in the design of clinical trials, for ethics committees in the approval of clinical trial protocols and for regulatory authorities in relation to drug approvals, with a particular emphasis on diagnostic testing and patient selection.

Abstract
While the prevalence of supernumerary teeth (ST) is high in permanent dentition, the etiology of ST in humans remains unclear. However, multiple murine models of ST have elaborated on dated mechanisms traditionally ascribed to ST etiology: one involves the rescue of rudimental teeth, and the second considers the contribution of odontogenic epithelial stem cells. It remains unclear whether these mechanisms of ST formation in mice are applicable to humans. The third dentition is usually regressed apoptotic-that is, the teeth do not completely form in humans. Recently, it was suggested that ST result from the rescue of regression of the third dentition in humans. The present investigation evaluates the proportion of collected general ST cases that evinced a third dentition based on the clinical definition of ST derived from the third dentition. We also investigated the contribution of SOX2-positive odontogenic epithelial stem cells to ST formation in humans. We collected 215 general ST cases from 15,008 patients. We confirmed that the general characteristics of the collected ST cases were similar to the results from previous reports. Of the 215 cases, we narrowed our analysis to the 78 patients who had received a computed tomography scan. The frequency of ST considered to have been derived from the third dentition was 26 out of 78 cases. Evidence of a third dentition was especially apparent in the premolar region, was more common in men, and was more likely among patients with ≥3 ST. SOX2-positive odontogenic epithelial stem cells within the surrounding epithelial cells of developing ST were observed in non-third dentition cases and not in third dentition cases. In conclusion, the third dentition is the main cause of ST in humans. The odontogenic epithelial stem cells may contribute to ST formation in cases not caused by a third dentition.

Abstract
The changes in the corneal endothelium at the centre of the cornea were followed after intracapsular cataract extraction and penetrating keratoplasty, by means of specular microscopy and morphometry using a computerized image analyzer. The corneal endothelium undergoes progressive transformation in its size over a period of more than 1 year. In penetrating keratoplasty, progressive increase in the cell size appears to occur over a longer postoperative period. The injury to the iris leaves permanent tissue defects and this is due to insufficient fibroblastic activity of the iris. Iris injury probably initiates synthesis of prostaglandins (PGs) in the human eyes. Topical indomethacin prevents atropine-resistant miosis during aspiration of soft cataract and also reduces intraocular inflammation after intracapsular extraction of senile cataract. It is hypothesized that these responses are related to PG release induced by iris injuries. Topical indomethacin also reduces incidence and severity of the cystoid macular oedema after intracapsular cataract extraction, but systemic administration appears to have little effect. Indomethacin is accumulated in the ciliary processes of rabbits by temperature- and ouabain-sensitive processes and the accumulation is inhibited by probenecid and PGE. It is possible that indomethacin is subject to elimination from the eye by a similar process as are PGs, and this may account for poor intraocular penetration from the systemic route. This justifies topical application of this drug.

Abstract
Small-cell lung cancer (SCLC) is a subgroup of lung cancer with a high frequency of liver metastasis, which is a predictor of poor prognosis. Diffuse liver metastases of SCLC with no visible nodular lesions in the liver when examined using computed tomography (CT) are relatively rare; however, a few cases with rapid progression to acute liver failure that were diagnosed after death have been reported. In this paper, we report a 63-year-old man with diffuse liver metastases of SCLC that were histologically diagnosed using a transjugular liver biopsy while the patient was alive, even though no lesions were visible during a contrast-enhanced CT examination.

Abstract
BACKGROUND AND PURPOSE Caffeic acid phenethyl ester (CAPE) is a component of honey bee propolis that can induce expression of haem oxygenase-1 (HO-1). Because HO-1 induction has been suggested to protect dopaminergic neurons in the substantia nigra, we examined the effect of CAPE in experimental models of dopaminergic neurodegeneration. EXPERIMENTAL APPROACH Neuroprotective effect of CAPE was investigated in rat organotypic midbrain slice cultures and in vivo, using a mouse model of dopaminergic neurodegeneration induced by intranigral injection of LPS and intrastriatal injection of 6-hydroxydopamine. KEY RESULTS CAPE protected dopaminergic neurons in slice cultures from IFN-γ/LPS-induced injury. The effect of CAPE was inhibited by zinc protoporphyrin IX, an HO-1 inhibitor, and by neutralizing antibody against brain-derived neurotrophic factor (BDNF). A p38 MAPK inhibitor SB203580 prevented activation of NF-E2-related factor 2, attenuated increased expression of HO-1 and BDNF, and blocked the neuroprotective actions of CAPE. In the LPS-injected mouse model, daily intraperitoneal administration of CAPE protected dopaminergic neurons, up-regulated HO-1 and BDNF, and reduced the increase of activated microglia/macrophages. Neuroprotective effects of CAPE against LPS-induced injury was prevented by zinc protoporphyrin IX or anti-BDNF antibody. CAPE protected dopaminergic neurons and alleviated methamphetamine-induced rotational behaviour also in 6-hydroxydopamine hemiparkinsonian mice. CONCLUSION AND IMPLICATIONS CAPE is a novel type of neuroprotective agent whose actions are mediated by both HO-1 and BDNF. These findings may provide novel clues to develop neuroprotective agents for treatment of neurodegenerative disorders.

Abstract
It has been standard practice to embolise a pseudoaneurysm caused by penetrating trauma whenever it is found, even in the absence of overt symptoms. This is a case report of a renal pseudoaneurysm (RPA) caused by a stab wound, which was safely monitored and followed using colour Doppler ultrasonography. On day 1, angiography showed a pseudoaneurysm of the renal artery in the parenchyma and ultrasonography showed blood flow into the pseudoaneurysm. Although abnormal blood flow into the kidney was seen, there appeared to be no leakage of blood from the pseudoaneurysm. The abnormal flow disappeared on day 12 and the area of the pseudoaneurysm became unclear from day 13. This report suggests the possibility that RPA caused by a stab wound could be an indication for conservative therapy under the following conditions: the RPA is detected initially; close monitoring using a colour Doppler ultrasound is possible; there is no leakage of blood from the right subclavian artery and there is a 2-week period of observation.

Abstract
We examined the effect of interferon-alpha (IFN-alpha) in combination with tumor necrosis factor-a (TNF-alpha) on growth, differentiation and apoptosis in HL-60 human myeloid leukemia cells. IFN-alpha inhibited cell growth and induced apoptosis, but not differentiation, in HL-60 cells. IFN-alpha enhanced TNF-alpha-induced apoptosis. We also investigated the expression of c-Myc and Bcl-2 oncoproteins, which are implicated in the survival or death of a cell. The levels of c-Myc protein expression were not changed by IFN-alpha alone at 24hrs of treatment, but were down-regulated at 72 hrs, accompanied by the appearance of apoptotic cells. While, IFN-alpha did not affect the level of Bcl-2 protein expression during this cultivation time. Interestingly, a combination treatment of IFN-alpha with TNF-alpha showed a greater decrease of c-Myc expression than TNF-a alone at 24hrs. Whereas, IFN-alpha did not significantly modulate Bcl-2 expression levels which were down-regulated by TNF-alpha. Therefore, the enhancement of TNF-alpha-induced apoptosis by IFN-a might be closely associated with the greater down-regulation of c-Myc protein, rather than Bcl-2. In contrast, with rapid down-regulation of c-Myc expression caused by TNF-alpha, IFN-alpha down-regulated c-Myc rather late (at 72 hrs), suggesting that both cytokines have a distinct pathway regulating c-Myc protein expression. However, the enhancement of apoptosis in the combination treatment would suggest the presence of a common signaling pathway for induction of apoptosis at down-stream of c-Myc.

Abstract
BACKGROUND The aim was to determine the effects of a novel free radical scavenger, edaravone, 3-methyl-1-phenyl-2-pyrazoline-5-one (ED), against endothelial barrier dysfunction induced by acute oxidative stress in cultured human umbilical vein endothelial cells (HUVECs). METHODS To estimate the integrity of the HUVEC monolayer, transendothelial electrical resistance (TEER) was measured for 3 hours. We investigated the permeability change of the monolayer by measuring the concentration of fluorescence in isothiocyanate-labeled dextran (FITC-Dx), and estimated the degree of oxidative stress in terms of hydrogen peroxide (H2O2) in the apical chambers. RESULTS The TEER changes in both xanthine oxidase (XO)+xanthine (X) and X/XO+ED group were significantly lower than the control group (p < 0.001). The amount of 4 FITC-Dx in the XO+X group was significantly higher than the control group at 3 hours (p < 0.001). In the XO+X group, the concentration of H2O2 was significantly higher than control and the X/XO+ED group (p < 0.001 each). Thus, edaravone improved the disturbed endothelial barrier function induced by acute oxidative stress. CONCLUSIONS The permeability increase induced by acute oxidative stress was prevented by free radical scavenger edaravone significantly in vitro. This radical scavenger may have clinical applications to protect against endothelial barrier dysfunction.

Abstract
BACKGROUND/AIMS To examine the efficacy of prospectively performing endoscopic hemoclipping in patients with severe gastrointestinal bleeding by assessing in relation to the severity of the case. METHODOLOGY Endoscopic hemoclipping was performed in 44 patients in shock caused by severe gastrointestinal bleeding. The level of severity was categorized using two factors. One factor was the presence or absence of severe shock, and the other was the presence or absence of active bleeding at endoscopy. Age, blood transfusion volume, APACHE III score, coagulopathy, initial hemostatic, rebleeding and mortality rate were recorded in relation to those four subsets. If rebleeding occurred, the systolic blood pressure, heart rate and serum hemoglobin concentration were compared between the initial time of bleeding and rebleeding. RESULTS Initial hemostasis was successfully achieved in all cases. The severe shock group required significantly more blood transfusions. The most severe subset had the highest APACHE III score, and coagulopathy. Rebleeding occurred in seven cases in the severe shock group only. In the rebleeding group, the systolic body pressure was lower, heart rate was higher, and serum hemoglobin concentration was lower than the non-rebleeding group. Four patients, all in subset 1, died, but no patient died due to gastrointestinal bleeding. CONCLUSIONS The endoscopic hemoclipping method is very effective for severe gastrointestinal bleeding in shock. The severity of shock was a more important risk factor than the presence of active bleeding. Our category of severity is simple, it reflects the patients' clinical condition accurately, and is very useful for patients with gastrointestinal bleeding.

Abstract
We have measured the concentration of cartilage-derived retinoic-acid-sensitive protein (CD-RAP) in synovial fluid (SF) from the knees of 49 patients with osteoarthritis (OA) and 79 with rheumatoid arthritis (RA) in order to investigate the correlation between the type of joint disease and level of CD-RAP. The mean concentration of CD-RAP in synovial fluid was significantly higher in OA than in RA. The level of CD-RAP in the group of patients with mild OA was significantly higher than in the moderate or severe groups and that in the group with mild RA was also significantly higher than in the other RA groups and decreased with progression of the disease. Immunohistochemical studies showed expression of CD-RAP in the cytoplasm of chondrocytes in newly-formed fibrocartilage. Since CD-RAP is mainly produced in young and proliferating chondrocytes, our results suggest that the level of CD-RAP in synovial fluid reflects remodelling of articular cartilage and may be used as a marker to estimate objectively the restorative reaction of chondrocytes.

Abstract
We report herein a case of spontaneous rupture of the pancreaticoduodenal artery (PDA) associated with obstruction of the common hepatic artery. A 68-year-old man was admitted to our hospital following the sudden onset of severe upper abdominal pain. Computed tomography revealed a large mass formation in the peritoneal cavity. Hemorrhagic shock rapidly developed during the initial evaluation, necessitating an exploratory laparotomy to be performed in the emergency room. This revealed a large hematoma in the retroperitoneal space, and a ruptured PDA was sutured. Postoperative angiography showed obstruction of the common hepatic artery and also suggested that the source of the bleeding was the PDA. Thus, a diagnosis of spontaneous rupture of a PDA aneurysm associated with occlusion of the common hepatic artery was made. Following this case report, we discuss the development of true aneurysms of the PDA and the treatment of ruptured true PDA aneurysms resulting in shock.
