Abstract
Background Patients with cancer are treated with chemotherapeutics that cause adverse effects, including erectile dysfunction (ED). Objectives We investigated erectile function in rats after the administration of anticancer agents based on data retrieved through mining of the US Food and Drug Administration (FDA) Adverse Event Reporting System (AERS) database. Materials and methods The statistical signal strength for the association between anticancer drugs and ED was calculated using the reporting odds ratio (ROR). A drug–event combination was detected when the lower limit of the 95% confidence interval (CI) of the ROR exceeded 1.00. Rats were administered anticancer agents detected in the FDA AERS analysis. Erectile function was assessed using intracavernous pressure (ICP) and mean arterial pressure (MAP) analysis after electrical stimulation of the cavernous nerve. Statistical significance was determined using Welch's t‐test or two‐way ANOVA. Results Melphalan (L‐PAM; ROR = 4.72, 95% CI = 2.78–8.00), vincristine (VCR; ROR = 2.47, 95% CI = 1.54–3.97), docetaxel (DTX; ROR = 2.25, 95% CI = 1.28–3.95), methotrexate (MTX; ROR = 1.96, 95% CI = 1.39–2.75), and doxorubicin (DOX; ROR = 1.82, 95% CI = 1.07–3.19) enhanced ED risk. L‐PAM and MTX decreased the ICP/MAP ratio 1 week after administration. VCR and DOX decreased erectile function 4 weeks after administration. DTX decreased erectile function at all assessed time points. Discussion and conclusion Certain anticancer agents should be considered risk factors for ED. Our results provide possible treatment strategies for maintaining erectile function in cancer survivors, including careful erectile function monitoring after treatment.

Abstract
OBJECTIVES Emotion regulation processes, such as mindfulness, self-compassion, and acceptance, have been discussed as modifiable psychological factors related to middle-aged women's psychological distress and adjustment. Although these emotion regulation factors have been discussed separately, the question remains of which factors reflect the most variance in middle-aged women's health. Therefore, this study aimed to reveal the most relevant explanatory variable for middle-aged women's health: mindfulness, self-compassion, or acceptance. METHOD A total of 200 middle-aged women completed self-reported measures of depressive symptoms, menopausal symptoms, physical quality of life, mental quality of life, and well-being. RESULTS Correlation analysis showed that mindfulness, self-compassion, and acceptance were significantly associated with all variables of psychological distress and adjustment. Hierarchical multiple regression analysis revealed that acceptance significantly explained the most variance of depressive symptoms, menopausal symptoms, and mental quality of life. On the other hand, self-compassion significantly explained the greatest variance in well-being. CONCLUSIONS These findings suggest that, for middle-aged women, 'acceptance' is an important explanatory variable of psychological distress and 'self-compassion' is an important variable of psychological adjustment.

Abstract
Objectives The aim of this study was to investigate the effect of hyperglycaemia on oxidative stress markers and inflammatory and matrix gene expression within tendons of normal and diabetic rats and to give insights into the processes involved in tendinopathy. Methods Using tenocytes from normal Sprague-Dawley rats, cultured both in control and high glucose conditions, reactive oxygen species (ROS) production, cell proliferation, messenger RNA (mRNA) expression of NADPH oxidase (NOX) 1 and 4, interleukin-6 (IL-6), matrix metalloproteinase (MMP)-2, tissue inhibitors of matrix metalloproteinase (TIMP)-1 and -2 and type I and III collagens were determined after 48 and 72 hours in vitro. In an in vivo study, using diabetic rats and controls, NOX1 and 4 expressions in Achilles tendon were also determined. Results In tenocyte cultures grown under high glucose conditions, gene expressions of NOX1, MMP-2, TIMP-1 and -2 after 48 and 72 hours, NOX4 after 48 hours and IL-6, type III collagen and TIMP-2 after 72 hours were significantly higher than those in control cultures grown under control glucose conditions. Type I collagen expression was significantly lower after 72 hours. ROS accumulation was significantly higher after 48 hours, and cell proliferation after 48 and 72 hours was significantly lower in high glucose than in control glucose conditions. In the diabetic rat model, NOX1 expression within the Achilles tendon was also significantly increased. Conclusion This study suggests that high glucose conditions upregulate the expression of mRNA for NOX1 and IL-6 and the production of ROS. Moreover, high glucose conditions induce an abnormal tendon matrix expression pattern of type I collagen and a decrease in the proliferation of rat tenocytes. Cite this article: Y. Ueda, A. Inui, Y.

Abstract
We previously developed a new bioreactor of the bioartificial liver composed of non-woven fabric. We have also experimented with hepatocyte spheroids, with the aim of improving the efficiency of this NWF bioreactor. In this study, we compared the efficiencies of NWF bioreactors employing hepatocyte spheroids versus single hepatocytes. Hepatocytes were isolated from a whole pig liver by Seglen's method. 1.0 × 1010 single hepatocytes were immobilized in the NWF bioreactor. Another 1.0 × 1010 hepatocytes were allowed to form spheroids by 24 hr suspension culture in a 4-L culture vessel, before being immobilized in the bioreactor. Hepatocyte spheroids were found to be functionally superior, on a per-cell basis, to single hepatocytes in the NWF bioreactor. However, the NWF bioreactor employing hepatocyte spheroids exhibited lower efficiency than that employing single hepatocytes, because the total number of the hepatocytes had decreased during the 24 hr suspension culture.

Abstract
To obtain a large number of porcine hepatocyte aggregates (spheroids) that have great potential in a bioartificial liver (BAL), we performed spheroid formation at a high cell density in a 1-L-scale spinner flask fitted with a silicon tubing apparatus for oxygen supply. We thereby obtained, within 24 hours, approximately fifty times more porcine hepatocyte spheroids as compared with the results of previous reports. The amount obtained corresponds to 2.5×109 cells and to roughly one-sixth of the cell number required for a BAL for a human patient. When we cultured spheroids continuously in suspension, they expressed three times more albumin secretion and twice the ammonium removal as compared with conventional monolayers during 10 days culture. Collagen gel entrapment of spheroids particularly lowered albumin secretion. We therefore conclude that the supension culture vessel of porcine hepatocyte spheroids is one of the most promising module types.

Abstract
The feasibility of University of Wisconsin (UW) solution in short-term hypothermic preservation of porcine hepatocyte spheroids was investigated, because they have great potential in bioartificial liver (BAL) systems. Porcine hepatocyte spheroids preserved for 3 days expressed almost comparable levels of albumin secretion as those without preservation, during 8 subsequent days of recultivation in continuous rotational culture, whereas isolated single cells did not reorganize into spheroids and completely lost their function in recultivation. Although for 3-day–preserved spheroids, the albumin secretion was lowered immediately after recultivation (Days 0–2), it was completely restored to that of nonpreserved ones. The function was completely lost in recultivation for 7-day–preserved ones. These results demonstrate that reorganization into spheroids is effective in preventing the functional loss of porcine hepatocytes occurring in hypothermic preservation, and that spheroid formation should precede the preservation as long as spheroid culture is finally used in BAL systems. Also, porcine hepatocyte spheroids are shown to be satisfactory stored in UW solution up to 3 days without significant cellular or functional loss.

Abstract
Objectives Triamcinolone acetonide (TA) is widely used for the treatment of rotator cuff injury because of its anti-inflammatory properties. However, TA can also produce deleterious effects such as tendon degeneration or rupture. These harmful effects could be prevented by the addition of platelet-rich plasma (PRP), however, the anti-inflammatory and anti-degenerative effects of the combined use of TA and PRP have not yet been made clear. The objective of this study was to determine how the combination of TA and PRP might influence the inflammation and degeneration of the rotator cuff by examining rotator cuff-derived cells induced by interleukin (IL)-1ß. Methods Rotator cuff-derived cells were seeded under inflammatory stimulation conditions (with serum-free medium with 1 ng/ml IL-1ß for three hours), and then cultured in different media: serum-free (control group), serum-free + TA (0.1mg/ml) (TA group), serum-free + 10% PRP (PRP group), and serum-free + TA (0.1mg/ml) + 10% PRP (TA+PRP group). Cell morphology, cell viability, and expression of inflammatory and degenerative mediators were assessed. Results Exposure to TA significantly decreased cell viability and changed the cell morphology; these effects were prevented by the simultaneous administration of PRP. Compared with the control group, expression levels of inflammatory genes and reactive oxygen species production were reduced in the TA, PRP, and TA+PRP groups. PRP significantly decreased the expression levels of degenerative marker genes. Conclusions The combination of TA plus PRP exerts anti-inflammatory and anti-degenerative effects on rotator cuff-derived cells stimulated by IL-1ß. This combination has the potential to relieve the symptoms of rotator cuff injury. Cite this article: T. Muto, T. Kokubu, Y. Mifune, A. Inui, R. Sakata, Y. Harada, F. Takase, M. Kurosaka.

Abstract
Adoptive immunotherapies have been developed for antiviral agent-refractory cytomegalovirus (CMV) disease after stem cell transplantation (SCT). However, the application of such strategies is limited, particularly in terms of need for donor cooperation regarding blood sampling and inaccessibility in the setting of cord blood transplantation. Herein, we describe the first successful treatment of antiviral agent-refractory CMV enteritis after allogeneic SCT by the infusion of ex vivo-expanded donor-derived CD4(+) lymphocytes obtained from the recipient's peripheral blood.

Abstract
Serotonin (5-hydroxytryptamine; 5-HT) is known to be activated during ischemia-reperfusion and triggers contractile dysfunction and pathological apoptosis. Here, the beneficial effects of the selective serotonin reuptake inhibitor (SSRI) fluvoxamine was demonstrated on ischemia-reperfusion injury in guinea-pig hearts perfused using the Langendorff technique. The recovery (%) of left ventricular developed pressure (LVDP) by fluvoxamine (5×10(-8) M) was 95.4% (control: 32%), which was consistent with the inhibition of mitochondrial Ca(2+)([Ca(2+)]m) uptake induced by changes in the Ca(2+) content and acidification of the perfusate, and similar to reperfusion following global ischemia in Langendorff-perfused hearts. Fluvoxamine inhibited the increase in [Ca(2+)]m induced by changes in the Ca(2+) content of the perfusate in perfused preparations of mitochondria, which was similar to the results obtained with the mitochondrial permeability transition pore (MPTP) opener atractyroside. The terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labeling (TUNEL)-positive cells were significantly less in fluvoxamine-treated hearts than in control hearts, with decreases in caspase-3 activity. These results suggest that SSRI inhibits opening of the MPTP by preventing [Ca(2+)]m overload-induced apoptosis related to the endogenous accumulation of 5-HT in ischemia-reperfusion hearts.

Abstract
Objectives To investigate the appropriate dose and interval for the administration
of triamcinolone acetonide (TA) in treating tendinopathy to avoid
adverse effects such as tendon degeneration and rupture. Methods Human rotator cuff-derived cells were cultured using three media:
regular medium (control), regular medium with 0.1 mg/mL of TA (low
TA group), and with 1.0 mg/mL of TA (high TA group). The cell morphology,
apoptosis, and viability were assessed at designated time points. Results In the low TA group, the cells became flattened and polygonal
at seven days then returned to normal at 21 days. The cell apoptosis
ratio and messenger ribonucleic acid expression of caspase-3, 7,
8, and 9 increased, and viability was reduced in the low and high
groups at seven days. In the low TA group, apoptosis and viability returned
to normal at 21 days, however, in the high TA group, the cell morphology,
apoptosis ratio, caspase-3, 7, 8, and 9 and viability did not return
by day 21. Re-administration was performed in the low TA group at
7-, 14-, and 21-day intervals, and cell viability did not return
to the control level at the 7- and 14-day intervals. Conclusion A 0.1 mg/mL dose of TA temporarily decreased cell viability and
increased cell apoptosis, which was recovered at 21 days, however,
1 mg/mL of TA caused irreversible damage to cell morphology and
viability. An interval > three weeks was needed to safely re-administer
TA. These findings may help determine the appropriate dose and interval
for TA injection therapy. Cite this article: Bone Joint Res 2014;3:328–34.

Abstract
BACKGROUND The association between overtime and depression is unclear and very few studies have examined the association between heavy overtime work, i.e. working more than 60 h per week, and depression. AIMS To examine the association between heavy overtime work and the onset of depressive disorder among male workers. METHODS A 1-year follow-up cohort study of male workers in a manufacturing company in Japan, between 2008 and 2009. Working hours, depressive disorder, assessed by the Center for Epidemiologic Studies Depression (CES-D) Scale (score ≥16 points), and covariates were measured at baseline and at follow-up. Participants who had depressive disorder at baseline were excluded. RESULTS At follow-up, 1194 participants aged between 18 and 71 years were analysed. Multiple logistic regression analysis revealed that the odds ratio for the new onset of depressive disorder was 4.5 (95% CI 1.8-11.1) times higher for employees working >60 h per week than for those working ≤50 h per week, when adjusted for age, lifestyle factors, work-related characteristics and socio-demographic characteristics at baseline and working hours at follow-up. However, the correlation between working 50.1 to 60 h per week and depressive disorder was not significant. The trend test of depressive disorder among groups by working hours was significant (P < 0.01). CONCLUSIONS Heavy overtime work is a risk factor for the new onset of depressive disorder in this population of male workers. Working >60 h per week may be the cut-off to screen for high-risk groups who need preventive action against depressive disorder.

Abstract
We investigated the relationship between the frequency of the common cold and the conditions of the body's immune system among members of a generally healthy population. Self-reporting questionnaires on the frequency of the common cold and on fatigue and stress conditions were administered to a total of 67 healthy individuals aged 22 to 50. The activities of natural killer (NK) cells, which were determined by Eu(3+)-DTPA release assay, and of NK cell members in the peripheral blood of the subjects were phenotypically (CD3 CD16(+) CD56(+)) analyzed with three-color flow cytometry. The results showed that the frequency of the common cold was significantly correlated with NK activity and NK subset (CD3(-)CD16(+) CD56(+)) frequency (r=-0.34 and-0.47 respectively, P<0.01). After adjusting for age, the mean NK subset (CD3(-)CD16(+)CD56) significandy differed (F=3.384, P<0.05) among the four frequency groups for the common cold, and the frequencies of the common cold were significandy different among the four stress/fatigue groups (F=8.016, P<0.001) for the males, as evaluated by ANCOVA. These results indicate that conditions of high stress and fatigue may increase the chance of catching the common cold due to a decrease in activities of NK cells.

Abstract
BACKGROUND Inhaled corticosteroid (ICS) therapy has improved the quality of life (QOL) for many asthmatics and reduced mortality rates associated with asthma. However, some patients do not obtain therapeutic benefit despite satisfactory adherence. OBJECTIVES To determine whether asthmatic patients were using ICS devices appropriately, and to clarify relationships between these results and QOL. SUBJECTS AND METHODS We studied 100 adult asthmatics, divided into two groups: 50 patients consecutively registered as using Diskus (fluticasone; D-group) and 50 consecutively registered as using Turbuhaler (budesonide; T-group). We measured peak inspiratory flows (PIFs) using the In-Check Dial device. Subjects also completed the Asthma Control Test for evaluation of QOL. RESULTS In the D-group, no patients showed PIF below the optimal range (30-90 L/min), whereas 52% of patients had PIF≥91 L/min. In the T-group, 6% of patients showed PIF over the optimal range (60-90 L/min), and 44% had PIF≤59 L/min. When patients in the T-group were required to deliberately make a maximal inhalation, 14% still had PIF≤59 L/min. The proportion of patients with poor control was significantly greater in the T-group than in the D-group. According to univariate logistic regression analyses, low PIF tended to be associated with poor asthma control in the T-group. No significant correlation was found between PIF and age in the D-group, but PIF decreased significantly with age in the T-group. CONCLUSIONS Appropriate measures for patients in whom PIF has been judged as lower than optimal include adequate education for inhalation and/or changing to a different inhalation device. These measures should be kept in mind for elderly asthma patients in particular, where appropriate selection of a corticosteroid inhalation device in the early stages of therapy would also be important.

Abstract
OBJECTIVES Although some prospective cohort studies have shown that baseline BMI is positively associated with a future incident risk for hypertension, these studies do not account for weight changes during the observation period. Therefore, it is not evident whether future incident risk for hypertension in obese, non-hypertensive people increases when their weight remains stable. We examined the association between long-term weight stability and risk for developing hypertension. METHODS A total of 5201 Japanese male workers aged 30-59 years underwent health checkups in 2002 and were followed through 2006. To consider transitions in covariates during the follow-up period, we used a time-dependent covariate Cox proportional hazard model to compute the relative risks (RRs) of incident hypertension. Furthermore, as a complementary analysis, we restricted the data to individuals whose BMI remained unchanged (± 5% of baseline BMI) during the follow-up and compared the RRs between BMI categories. RESULTS During the follow-up, there were 899 newly diagnosed cases of hypertension among the 5201 men (14,888 person-years). Mean change in BMI during the follow-up period of all subjects was 0.2 ± 1.1 kg/m(2) (range: -6.6 to 6.3 kg/m(2)). The multivariate RRs for hypertension increased as BMI increased when we applied the time-dependent covariate Cox proportional hazard model. The complementary analysis showed that the multivariate RR (confidence interval) within the ≥ 27.0 kg/m(2) BMI category was 1.43 (1.16-1.77) times higher than the reference of 23.0-24.9 kg/m(2), whereas the RR for the <21.0 kg/m(2) BMI category was 0.63 (0.51-0.79) times lower than the reference. CONCLUSIONS A higher baseline BMI increases future incident risk for hypertension even when there has been no major weight increase. Weight management should be encouraged for obese, non-hypertensive people to prevent future hypertension.

Abstract
BACKGROUND To determine the preferable method for self-injecting insulin, we compared the handling, safety, and dose accuracy of a conventional disposable syringe and vial with FlexPen (Novo Nordisk A/S, Bagsvaerd, Denmark), a prefilled pen. METHODS Insulin therapy-naive healthcare professionals (HCPs) (n = 30), unfamiliar with insulin delivery, injected 10 U of insulin into a sponge pad using either a syringe and vial or the FlexPen, both with 30-gauge 8-mm needles, on day 1. The following day, they used the alternative method. They evaluated the handling of the two methods on device-specific questionnaires and compared overall preference on a third questionnaire. To evaluate dose accuracy, 30 insulin therapy-experienced HCPs and 20 insulin therapy-naive HCPs were asked to deliver 10 U of insulin using each method, and the amount discharged was weighed. RESULTS FlexPen was rated easier to use and overall more preferable than the syringe and vial by insulin therapy-naive HCPs (P < 0.001). The pen device was more accurate than the syringe and vial when used by experienced HCPs (mean +/- SD dose delivered, 9.91 +/- 0.11 U vs. 9.82 +/- 0.25 U, respectively; P < 0.001) and by insulin therapy-naive HCPs (9.91 +/- 0.12 U vs. 9.74 +/- 0.85 U; P < 0.001). CONCLUSIONS Insulin therapy-naive HCPs found FlexPen easier to handle and preferable to use compared to a conventional syringe and vial. Both insulin therapy-experienced and -naive HCPs were able to deliver insulin significantly more accurately with the FlexPen than with a syringe and vial (P < 0.001).

Abstract
OBJECTIVE Preoperative use of emission tomography with(18)F-fluorodeoxyglucose (FDG-PET) in patients with primary colorectal cancer remains controversial. This study evaluated the additional value of FDG-PET in comparison with routine multidetector row computed tomography (MDCT) in patients with primary colorectal cancer. METHOD Retrospective analysis was performed in 65 patients with colorectal cancer who underwent whole-body FDG-PET. Results of FDG-PET were compared with routine preoperative evaluation by MDCT regarding detection of primary tumour, lymph node involvement and distant metastases. All images were evaluated before surgery. RESULTS Tumour detection rate was 100% (63/63) for MDCT and 98% (62/63) for FDG-PET. Lymph node involvement was pathologically confirmed in 35 patients. MDCT and FDG-PET displayed sensitivities of 89% (31/35; 95% CI: 73-97%) and 43% (15/35; 95% CI: 26-61%) and specificities of 52% (11/21; 95% CI: 30-74%) and 95% (20/21; 95% CI: 76-100%), respectively. Liver metastases were present in 22 patients. MDCT and FDG-PET showed accuracies of 98% (64/65; 95% CI: 92-100%) and 97% (63/65; 95% CI: 89-100%), respectively. FDG-PET detected additional extrahepatic metastatic lesions and affected treatment plan compared with MDCT in 10 patients. CONCLUSION Preoperative FDG-PET is not superior to MDCT for detection of primary tumour, lymph node involvement or liver metastases, but may have potential clinical value in patients with advanced colorectal cancer by detecting extrahepatic distant metastases.

Abstract
The type IV pili of plasmid R64 belonging to the type IVB group are required only for liquid mating. They consist of the major and minor components PilS pilin and PilV adhesin, respectively. PilS pilin is first synthesized as a 22-kDa prepilin from the pilS gene and is then processed to a 19-kDa mature pilin by PilU prepilin peptidase. In a previous genetic analysis, we identified four classes of the pilS mutants (T. Horiuchi and T. Komano, J. Bacteriol. 180:4613-4620, 1998). The products of the class I pilS mutants were not processed by prepilin peptidase; the products of the class II mutants were not secreted; in the class III mutants type IV pili with reduced activities in liquid mating were produced; and in the class IV mutants type IV pili with normal activities were produced. Here, we describe a novel class, class V, of pilS mutants. Mutations in the pilS gene at Gly-56 or Tyr-57 produced type IV pili lacking PilV adhesin, which were inactive in liquid mating. Residues 56 and 57 of PilS pilin are suggested to function as an interface of PilS-PilV interactions.

Abstract
14552 Background: Oxaliplatin-based regimen (FOLFOX regimen) for patients with colorectal cancer have improved survival. Neurotoxicity is the most frequent dose-limiting toxicity of oxaliplatin. Various strategies and pharmacologic agents are currently under investigation to prevent or treat oxaliplatin-induced neurotoxicity. One of them is Stop-and-Go strategy based on the observation of reversibility of the neurotoxic symptoms after discontinuation of oxaliplatin. Stop-and-Go concept will prolong the time of oxaliplatin-based therapy as long as antitumor efficacy is still maintained. Methods: Patients with a histologically verified advanced colorectal carcinoma were eligible for the study. From April 2005 to March 2006 at Cancer Institute Hospital, 187 patients whom treated with bimonthly oxaliplatin-based regimen (FOLFOX4) were enrolled. An oxaliplatin specific neurotoxicity scale are distinct from the National Cancer Institute common toxicity criteria classification (CTC-AE vol. 3). This study was performed to carefully assess the onset and duration to recovery of oxaliplatin neurotoxicity and resumption rate of FOLFOX4. Results: Neurotoxicity was observed in 72 patients with Grade 1, 56 patients with Grade 2 and 33 patients with Grade 3. Oxaliplatin-induced cumulative neurotoxicity develops progressively. The median cumulative doses of oxaliplatin were 170 mg/m2 with Gr. 1; 845.8 mg/m2 with Gr. 2; and 850 mg/m2 with Gr. 3. The median time to onset were 16 days with Gr. 1; 174 days with Gr. 2; and 177 days with Gr. 3. The median time to recovery after stopping the therapy and the median time to progression during the discontinuation of oxaliplatin were 56 and 59 days, respectively, in patients allocated to Gr. 2 compared with 106 and 73 days, respectively, in patients allocated to Gr. 3. The recovery time during the discontinuation showed a statistically significant reduction of the values in the Gr. 2 but not in Gr. 3 (p = 0.0024). The resumption rates of oxaliplatin were 73.7% with Gr. 2 and 46.4% with Gr. 3. Conclusions: Our results may focus to manage time course of Stop-and-Go strategy in clinical practice.

Abstract
14569 Background: Allergic reaction to oxaliplatin is a chronic adverse event in the treatment of cancer. Patients with colorectal cancer were given FOLFOX4, using preventive approaches composed of two steps. Methods: Step I included 40 mg famotidine, 8 mg dexamethasone from the first cycle and 50 mg of diphenhydramine after cycle 4. In step II, for the patients who had a reaction but not a severe one in step I, a 20 mg dose of dexamethasone and four-hour oxaliplatin infusion were administered. Results: Forty-eight patients (15.1%) presented with allergic reaction, divided into group A receiving step I except diphenhydramine and B undergoing all of step I. Significant delay on occurrence was observed in group B. Thirty patients underwent step II. Prevention success (well-prevented) was defined as no reaction in two or more treatments. Allergic reaction appeared again in eleven patients (not well-prevented, 36.7%), but most well-prevented patients got four months longer treatment time with no reaction than not well-prevented patients. Conclusions: In our preventive approach, administration of H-1RA was effective in delaying the occurrence of allergic reaction to oxaliplatin, and increased dose of dexamethasone 20 mg and prolongation of oxaliplatin infusion from 2 to 4 hours was succeeded in continuing the FOLFOX4.

Abstract
BACKGROUND An aberrant left hepatic artery (ALHA) is occasionally encountered during esophagogastric surgery. However, at curative gastrectomy for gastric cancer, it is questionable as to whether the ALHA need to be divided in order to maximize lymph node clearance and the issue requires clarification. METHODS We encountered 50 patients with an ALHA during curative gastrectomy for gastric cancer between 1997 and 2001. Data concerning operative feasibility, postoperative liver function and therapeutic value of nodal dissection were analyzed retrospectively. RESULTS For 27 patients, we preserved the ALHA, and for the remaining 23 patients, we divided the ALHA at the origin of the left gastric artery (LGA). Serum levels of aspartate aminotransferase and alanine aminotransferase were statistically significant higher on postoperative day (POD) 1 (P=0.0008 and P=0.0007), and on POD 3 (P=0.001 and P=0.008), respectively, in the ALHA-divided group. Patients who underwent a total gastrectomy predominated in the ALHA-divided group, the total number of dissected lymph nodes being higher in the ALHA-divided group (P=0.018). However, the total numbers of dissected lymph nodes and metastatic lymph nodes around the LGA were similar in the 2 groups (P=0.447 and P=0.128), respectively. No significant differences were seen between the 2 groups in morbidity and mortality. The overall 5-year survival rates were also comparable. CONCLUSIONS Although a prospective study is required, this study suggested that routine division of the ALHA may not always be required for curative gastrectomy.

Abstract
Positive surgical indications for an only hearing ear were evaluated in order to improve patients' quality of life. Fifteen cases of surgery involving an only hearing ear over the past eight years were retrospectively reviewed. Of eight perforated chronic otitis media cases, seven underwent type one tympanoplasty and one underwent simple underlay myringoplasty regardless of otorrhoea at the time of surgery. Of six cholesteatoma cases, two received the canal wall up method and four received the canal wall down method. Ossiculoplasty was carefully performed in six cases. Hearing was improved in seven cases, whereas it remained unchanged in seven cases and deteriorated in one case. Of nine patients, two did not need a hearing aid after surgery. Five patients with severe combined hearing loss (>90 dB) were able to communicate with a hearing aid, alleviating their anxiety regarding hearing loss. Only hearing ears with chronic otitis media and cholesteatoma can be successfully treated by tympanoplasty with or without ossiculoplasty.

Abstract
Each individual and pure catechin isolated from green tea was investigated as to its myocardial or blood pressure effects. The nitric oxide (NO) electrode and fluorometry were used to monitor changes in the NO and Ca(2+) contents of the heart, together with simultaneous recordings of the left ventricular developed pressure. The low dose of (-)-epigallocatechin-3-gallate (EGCg: 10(-6), 10(-5 )M) increased the left ventricular developed pressure with elevation of the transient fura-2 Ca(2+) signal (T(Ca)), but the high dose of EGCg (10(-4 )M) produced a maximum left ventricular developed pressure with decreases in the basal level of T(Ca) in a manner similar to the administration of the Ca-sensitizer pimobendan. However, the level of the transient NO signal (T(NO)) increased dose-dependently without any increases in the width of T(NO). In the isolated right atria, the contractile force of (-)-gallocatechin-3-gallate (GCg) at 10(-8)-10(-4 )M produced the highest pD(2) value, 6.7, in catechins (EGCg: 5.2, pimobendan: 5.1), but did not affect the heart rate. GCg, an artifact due to the epimerization of EGCg during the heating procedure, showed the most prolonged hypotensive effect in rabbits among the catechins. Each catechin (GCg or EGCg), like the NO donor, may have a therapeutic use as an NO-mediated vasorelaxant and may have an additional protective action in myocardial ischemia-reperfusion induced injury.

Abstract
BACKGROUND Reflux oesophagitis is commonly encountered in the surgical treatment of cancer of the upper third of the stomach. The aim of this study was to describe a novel surgical technique and evaluate the clinical outcome of high segmental gastrectomy for early-stage proximal gastric cancer. METHODS Thirty consecutive patients with early gastric cancer located in the upper third of the stomach were included, of whom 12 underwent high segmental gastrectomy and 18 underwent proximal gastrectomy with jejunal interposition. The incidence of reflux oesophagitis and nutritional parameters were compared between the two groups at 1 year after operation. RESULTS One patient had mild reflux symptoms and two had endoscopic evidence of oesophagitis 1 year after high segmental gastrectomy. Half of the patients who had proximal gastrectomy had reflux symptoms of varying severity and 14 had endoscopic evidence of oesophageal changes at 1 year after surgery. There were significant differences between groups in the incidence of reflux symptoms (P = 0.016) and endoscopically detected gastro-oesophagitis (P < 0.001). There were no adverse events in either group, and the survival rate after high segmental gastrectomy appeared favourable. CONCLUSION Selected patients with early-stage proximal gastric cancer benefit from high segmental gastrectomy in terms of reduced reflex oesophagitis, without jeopardizing curability.

Abstract
BACKGROUND Cyclosporine A (CsA) has been widely used in children with steroid dependent and steroid resistant nephrotic syndrome (NS) because of its efficacy in relieving these patients from systemic side effects of steroids. However, its long term use is controversial, since chronic CsA induced nephropathy (CsAN) may develop in a considerable number of patients. AIMS AND METHODS In order to clarify the risk factors for the development of CsAN, the clinical characteristics of children with steroid dependent or steroid resistant NS taking CsA (target blood trough levels 50-150 ng/ml) for more than six months, managed at a single centre, were retrospectively analysed. RESULTS Thirteen of 30 children (24 boys and 6 girls) taking CsA (mean duration 43 months, range 6-144) had CsAN defined as the presence of CsA associated arteriopathy with or without striped tubulointerstitial lesions. The multivariate analysis revealed that CsA treatment for more than 36 months and an age younger than 5 years at the start of CsA treatment were independent risk factors for the development of CsAN. The univariate analysis also showed that patients with CsAN had more frequent relapses during CsA treatment than those without CsAN. CONCLUSION An alternative treatment should be seriously considered after a 36 month administration of CsA in order to prevent CsAN. Data also suggest that CsA treatment in children younger than 5 years should be avoided if possible.

Abstract
3620 Background: No global consensus has been established on the crucial determinants of metastasis in colorectal carcinoids. This study aims to determine the predictive factors for lymph node (LN) and distant metastasis, and to provide strategic model for the treatment of this uncommon disease. Methods: All patients diagnosed as carcinoids from 1984 to 1998 were extracted from the nationwide database, “Multi-Institutional Registry of Large-Bowel Cancer in Japan”, which covers almost 10% of all colorectal cancers in Japan. Risk factors for metastasis were analyzed among colorectal carcinoids undergoing surgery. Results: Among 90,057 cases of colorectal tumors registered from 1984 to 1998, a total of 345 cases of carciniods were identified. All cases were from the Asian population. The site distribution consisted of the ileum 3 (0.9%), appendix 8 (2.3%), colon 28 (8.2%) and rectum 304 (88.6%). Among colorectal carcinoids, a total of 263 cases undergoing surgery were eligible for the analysis (colon 23, rectum 240). Overall incidence of LN and distant metastasis were 29% and 7%, respectively. Univariate analysis showed that age>55, tumor size, tumor invasion≥T2, and lymphovascular invasion were associated with LN metastasis as well as distant metastasis. Multivariate analysis revealed that tumor size>10mm and lymphovascular invasion (LVI) were independently predictive of LN metastasis, while tumor size>20mm was a single risk factor for distant metastasis. Notably, tumors not larger than 10mm and without LVI exhibited no LN metastasis ( Table ). Conclusions: Tumors not larger than 10mm and without LVI could be curatively treated by endoscopic resection or transanal excision. However, tumors larger than 10mm or those with LVI should undergo radical surgery for LN dissection. Furthermore, tumors larger than 20mm carry a high risk for distant metastasis, and require close follow-up even without evident metastasis at the time of surgery.

Abstract
13574 Background: Oxaliplatin is a well-known platinum compound as a key agent of FOLFOX regimen, the world standard chemotherapy in colorectal cancer. Allergic reaction due to oxaliplatin is a chronic adverse event regarded as almost type I allergy. In our institute, we have also experienced allergic reaction including severe cases and started to apply practical preventive approach to the patients treated with FOLFOX regimens. Methods: Preventive approach was as follows: 40mg of famotidine and 8mg of dexamethasone before oxaliplatin infusion were given to all patients from the initial cycle and 50mg of diphenhydramine after cycle 4. Further intensive anti-allergic procedure was performed for the patients who showed any allergic reactions against initial preventive approach. Increased dose of dexamethasone to 20mg and diphenhydramine were administered before oxaliplatin infusion and oxaliplatin was prolonged from 2 up to 4 hours for patients with grade 1, 2 allergic reactions (CTCAE v3.0). Treatment was discontinued in patients with severe grade 3 adverse events. Results: 139 patients received FOLFOX regimens during 6 months. 15 patients (10.8%) presented with allergic reaction, 11 (73.3%) of those were grade 1, 2 and the other 4 (26.7%) were grade 3. Immediate discontinuation of oxaliplatin infusion and administration of antihistaminic drugs, steroid or rapid infusion were routine proceeding, and almost of the patients entirely recovered within 2 hours. 9 patients were re-exposed to oxaliplatin using the preventive approach and grade1 reaction appeared in 3 patients (33.3%) again. Conclusions: Our initial preventive approach was effective to reduce the incidence of allergy, severe adverse events. And further intensive anti-allergic procedure contributed to re-expose to oxaliplatin. No significant financial relationships to disclose.

Abstract
13544 Background: Development of colorectal cancer is a well-known long-term complication of ulcerative colitis (UC). However, specific clinical features of UC-associated colorectal cancer have been controversial mainly due to the small number of cases, especially in the Asian countries. This study aims to clarify the clinicopathological features of UC-associated colorectal cancer compared with non-UC-associated colorectal cancer in Japan, using a large nationwide database. Methods: All patients pathologically diagnosed as colorectal cancer from 1978 to 1998 were extracted from the nationwide database, “Multi-Institutional Registry of Large-Bowel Cancer in Japan”, which covers almost 10% of all colorectal cancers in Japan. Clinicopathological factors were compared between those associated with UC and the others. Survival analysis in each TNM stage was performed using the Kaplan-Meier method. Results: Among 108,536 cases of colorectal tumors registered from 1978 to 1998, a total of 169 cases of UC-associated colorectal cancers were identified. All cases were from the Asian population. UC-associated cases showed higher prevalence of females, younger age, higher incidence of multiple cancers, and higher incidence of mucinous adenocarcinomas. On the other hand, there were no differences in tumor sites, family history of colorectal cancer, lymph node metastasis, distant metastasis, TNM stage, and CEA level adjusted by TNM stage between the two groups. Survival analysis revealed poorer prognosis in UC-associated colorectal cancers at TNM stage 3. Conclusions: UC-associated colorectal cancer showed unique histological features compared with usual colorectal cancer. The survival of UC-associated colorectal cancer with lymph node metastasis was poorer than usual colorectal cancer, and therefore, intensive adjuvant therapy and close follow-up is needed after surgery in this patient group.
