Abstract
Hemophagocytic lymphohistiocytosis (HLH) is a rare, life-threatening disorder characterized by systemic hyperinflammation. Although allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains the only potentially curative treatment for primary and relapsed/refractory HLH, the optimal strategy has not been established. We retrospectively analyzed 56 adult patients (≥18 years) with primary and secondary HLH (mainly consisting of Epstein-Barr virus-associated HLH) who underwent allo-HSCT using the registry database of the Japanese Society for Transplantation and Cellular Therapy, including 26 patients who underwent cord blood transplantation (CBT). One-fourth of patients received myeloablative conditioning (MAC), mainly consisting of total body irradiation-based regimens. The 3-year overall survival (OS) was 40.6%, while the 3-year cumulative incidences of relapse and non-relapse mortality (NRM) were 19.8% and 39.6%, respectively. In univariable analysis, age at allo-HSCT (the 3-year OS: 27.5% for ≥ 25 years old vs 58.0% for < 25 years old, P = .025), conditioning intensity (7.1% for MAC vs 51.8% for reduced-intensity conditioning (RIC), P = .002), and donor source (26.0% for CBT vs 52.9% for bone marrow or peripheral blood stem cell transplantation (BMT/PBSCT), P = .030) were associated with significantly inferior OS. In multivariable analysis, older age at allo-HSCT (≥ 25 years old) (Hazard ratio [HR], 2.37; 95% CI, 1.01 to 5.58; P = .048), MAC (HR, 2.45; 95% CI, 1.09 to 5.53; P = .031), and CBT (HR, 2.21; 95% CI, 1.04 to 4.71; P = .040) were independently associated with worse OS. In addition, only conditioning intensity predicted higher NRM (the 3-year NRM: 78.6% for MAC vs 26.6% for RIC), while no factors were associated with the relapse rate. This study includes the largest number of adult HLH patients undergoing CBT. Although the use of CBT is acceptable, BMT/PBSCT are more favorable strategies in allo-HSCT in adult HLH. Regarding conditioning intensity, RIC regimens are more beneficial in this setting.

Abstract
Objective The treatment background, as well as the frequency and type of complications, in autologous (auto-) and allogeneic (allo-) hematopoietic stem cell transplantation (HSCT) survivors influence the appearance of moderate to vigorous physical activity (MVPA) or sedentary behavior. We therefore assessed differences in the MVPA and sedentary behavior between auto- and allo-HSCT survivors. Methods This prospective observational study included 13 auto- and 36 allo-HSCT survivors (approximately 4 years after HSCT). The MVPA and sedentary behavior were assessed using a triaxial accelerometer. Results There were no significant between-group differences in the MVPA or sedentary behavior (p=0.768 and 0.739, respectively). In allo-HSCT survivors, the MVPA was negatively correlated with the Hospital Anxiety and Depression Scale score (r=-0.358, p=0.032). A stepwise multiple regression analysis showed that age was a significant predictor of sedentary behavior in allo-HSCT survivors (β=0.400, p=0.016). Conclusion We observed no significant between-group differences in the MVPA or sedentary behavior. Our results suggest that it may be unnecessary to change the rehabilitation program according to the donor type in interventions for promoting MVPA and reducing sedentary behavior in long-term HSCT survivors.

Abstract
Fostamatinib, a spleen tyrosine kinase inhibitor, has been approved for the treatment of chronic primary immune thrombocytopenia (ITP) in the United States, Canada and some European countries. We conducted a phase 3, placebo-controlled, double-blind, parallel-group study to evaluate the efficacy and safety of fostamatinib in Japanese patients with primary ITP. Thirty-four patients were randomised to fostamatinib (n = 22) or placebo (n = 12) at 100-150 mg twice a day for 24 weeks. Stable responses (platelet ≥50 000/μl at ≥4 of the 6 visits from weeks 14 to 24) were observed in eight (36%) patients on fostamatinib and in none of the patients on placebo (p = 0.030). Overall responses (platelet ≥50 000/μl at ≥1 of the 6 visits from weeks 2 to 12) were seen in 10 (45%) patients on fostamatinib and in none of the patients on placebo (p = 0.006). Patients on fostamatinib required rescue medication less often and experienced fewer bleeding symptoms than patients on placebo. Adverse events observed were mild or moderate and were manageable. No new safety signals were identified in Japanese patients with ITP.

Abstract
BACKGROUND Although rather favorable probabilities of return to work have been reported after allogeneic hematopoietic cell transplantation (allo-HCT), survivors often have difficulty continuing to work because of their immunocompromised status and diverse late effects after allo-HCT. We evaluated the incidence of and risk factors for recurrent sick leave in allo-HCT survivors after they initially returned to work. METHODS We targeted allo-HCT survivors who were employed at diagnosis, aged 20-64 at survey, and survived for ≥ 2 years without relapse. Of the 1904 survivors who were informed of the study, 1148 returned the questionnaire (60%), and 1048 eligible participants were included in the overall analysis. In the present study that considered recurrent sick leave after return to work, we targeted 896 participants who returned to work at least once after allo-HCT. Participants stated if they had recurrent sick leave after returning to work and its reasons, as well as associated patient-, HCT/HCT center-, and work-related factors and clinical events after allo-HCT. A logistic regression analysis was conducted to explore correlated factors for recurrent sick leave. RESULTS In survivors who returned to work, 30% required recurrent sick leave. The most frequent causes of recurrent leave were physical issues (72%), and analysis of free descriptions demonstrated that these were mainly associated with graft-versus-host disease, infection, or readmission. Other reasons included work-related issues such as gap between physical and working conditions. Multivariate analysis showed that cord blood transplantation, longer employment duration, and counseling from healthcare professionals were associated with a lower risk of recurrent leave. Readmission, immunosuppressant use, and symptoms involving the respiratory system, gut, and joints and muscles were associated with a higher risk. CONCLUSIONS Our results drawn from a large cohort study should help healthcare professionals identify and assist at-risk patients. Multi-professional teams that provide continuous support and effective communication with the workplace are necessary to improve long-term outcomes after allo-HCT. IMPLICATIONS FOR CANCER SURVIVORS In order to continue working after the initial return to work, it is important to receive counseling from healthcare professionals and obtain reasonable accommodation from workplace.

Abstract
The optimal combined chemotherapy regimen with rituximab has yet to be established for elderly patients with advanced-stage indolent B-cell lymphoma (B-NHL). A multicenter study was performed to evaluate the efficacy and toxicity of R-THP-COP therapy in elderly patients (aged 70–79 years) with newly diagnosed advanced-stage indolent B-NHL using the complete response rate (%CR) as the primary endpoint. Patients with newly diagnosed, clinical stage III/IV, indolent B-NHL, aged 70–79 years, with a performance status of 0–2 were eligible for this study. R-THP-COP consists of 375 mg/m2 of rituximab, 50 mg/m2 of pirarubicin, 750 mg/m2 of cyclophosphamide, 1.4 mg/m2 of vincristine, and 100 mg/day of oral prednisolone for 5 days. This study was discontinued due to poor accrual after the enrollment of 18 patients, although the planned sample size was 40 patients. The numbers of patients with follicular lymphoma, mucosa-associated lymphoid tissue lymphoma, and mantle cell lymphoma were 16, 1, and 1, respectively. The median age was 73 (range, 70 to 79) years. The %CR including unconfirmed CR was 45% (95% confidence interval: 25-66%) and the overall response rate was 72%. The estimated 5-year overall survival and progression-free survival rates were 55% and 28%, respectively. The major toxicity observed was grade 4 neutropenia (94%). Grade 4 non-hematological toxicities were not observed and no patients developed grade 3/4 cardiac toxicities. This phase II study provides useful information regarding the efficacy and toxicity of R-THP-COP therapy for patients aged 70 years or older with newly diagnosed, advanced-stage, indolent B-NHL, although the sample size was small.

Abstract
The optimal dosage of methotrexate (MTX) for graft-versus-host disease (GVHD) prophylaxis after cord blood transplantation (CBT) has not been well elucidated. Therefore, we conducted a retrospective study comparing a mini-MTX group (5 mg/m2 on day 1, 3 and 6) to a short-MTX group (10 mg/m2 on day 1 and 7 mg/m2 on day 3 and 6) after CBT. Sixty-three patients were classified as the mini-MTX group and 20 as the short-MTX group. The median time and cumulative incidence of neutrophil engraftment did not vary between the two groups. The cumulative incidence of grade 2-4 and grade 3-4 acute GVHD was similar in both groups. Overall survival in the mini-MTX group was significantly lower than in the short-MTX group (46.9% vs. 88.7% at 1 year, p < 0.01), contributing to higher non-relapse mortality (NRM) in the mini-MTX group (32.0% vs. 5.0% at 1 year, p = 0.02). In multivariate analysis, the mini-MTX regimen was the most powerful prognostic factor for OS (hazard ratio 4.11; p = 0.03). Although the reduced dosage of MTX had no effect on neutrophil engraftment, increased NRM due to higher incidence of infection, graft failure, and severe acute GVHD resulted in a lower survival rate in the mini-MTX group after CBT.

Abstract
Abstract
Background
Recently, wire-based resting indices have been recognized as gold standard for evaluating physiological lesion assessment. The resting full-cycle ratio (RFR) is a unique resting index which is calculated as the point of absolutely lowest distal pressure to aortic pressure during entire cardiac cycle. It is unclear whether the diagnostic performance of RFR for detecting functional coronary artery stenosis is similar in each coronary artery. The aim of this study is to compare the diagnostic performance of RFR based on target coronary vessel.
Method
This study was a prospectively enrolled observational study. A total of 156 consecutive patients with 220 intermediate lesions were enrolled in this study. The RFR was measured after adequately waiting for stable condition, while FFR was measured after intravenous administration of ATP (180mcg/kg/min). Lesions with FFR ≤0.80 were considered functionally significant coronary artery stenosis.
Results
In all lesions, reference diameter, diameter stenosis, lesion length, RFR, and FFR were 3.0±0.7mm, 45±13%, 13.0±8.8mm, 0.90±0.09, and 0.82±0.10, respectively. Functional significance was observed in 88 lesions (40%) of all lesions. RFR showed a significant correlation with FFR in overall lesions (r=0.774, p<0.001). The ROC curve analysis of RFR showed good accuracy for predicting functional significance (AUC 0.87, diagnostic accuracy 81%) in all subjects. Regarding each target vessel, there were similar and significant positive correlation between RFR and FFR (LAD; r=0.733, p<0.001, LCX; r=0.771, p<0.001, RCA; r=0.769, p<0.001, respectively). The prevalence of discordant between RFR and FFR was significantly different among 3 vessels (LAD 26%, LCX 12%, RCA 13%, respectively, p<0.05 for among 3 groups). Regarding the comparison of ROC curves according to lesion location, AUC was significantly lower in LAD than in LCX and RCA (LAD 0.780, LCX 0.947, RCA 0.926, p<0.01 for LAD compared to LCX, p<0.01 for LAD compared to RCA, respectively). Furthermore, the diagnostic accuracy was significantly different according to target vessel (LAD 74%, LCX 88%, RCA 87%, respectively, p<0.05 for among 3 vessels).
Conclusion
RFR demonstrated better diagnostic accuracy for evaluating functional lesion severity. The diagnostic performance of RFR was different based on target vessel. RFR is a unique and useful resting index, and it may detect functionally significant coronary stenosis that cannot be detected with other resting indices in daily practice.

Abstract
A66 -year-old man was diagnosed with chronic myeloid leukemia(CML). Imatinib treatment had been initiated, and a major molecular response(MMR)was achieved. The patient had anemia and was diagnosed with descending colon cancer. The patient was surgically treated, and then received postoperative adjuvant chemotherapy with UFT/LV. However, imatinib was not administered during that period. The patient could undergo postoperative adjuvant chemotherapy for 6 months without acute exacerbation of the CML.

Abstract
Nasal allergen challenge (NAC) is an important tool to diagnose allergic rhinitis. In daily clinical routine, experimentally, or when measuring therapeutic success clinically, nasal allergen challenge is fundamental. It is further one of the key diagnostic tools when initiating specific allergen immunotherapy. So far, national recommendations offered guidance on its execution; however, international divergence left many questions unanswered. These differences in the literature caused EAACI to initiate a task force to answer unmet needs and find a consensus in executing nasal allergen challenge. On the basis of a systematic review containing nasal allergen challenges of the past years, task force members reviewed evidence, discussed open issues, and studied variations of several subjective and objective assessment parameters to propose a standardized way of a nasal allergen challenge procedure in clinical practice. Besides an update on indications, contraindications, and preparations for the test procedure, main recommendations are a bilaterally challenge with standardized allergens, with a spray device offering 0.1 mL per nostril. A systematic catalogue for positivity criteria is given for the variety of established subjective and objective assessment methods as well as a schedule for the challenge procedure. The task force recommends a unified protocol for NAC for daily clinical practice, aiming at eliminating the previous difficulty of comparing NAC results due to unmet needs.

Abstract
Distal radius fractures (DRF) may trigger, reveal or decompensate acute carpal tunnel syndrome (CTS) in 0.5-21% of cases. Internal fixation and median nerve release must then be carried out urgently. Less invasive approaches have been described for both the median nerve release using an endoscopic device and for the DRF fixation using a volar locking plate. We assessed the feasibility of DRF fixation and median nerve release through a single, minimally-invasive 15mm approach on a series of 10 cases. We reviewed retrospectively 10 consecutive cases of DRF associated with symptomatic CTS in 8 women and 2 men, aged 57 years on average. CTS was diagnosed clinically. All patients were treated during outpatient surgery with a volar locking plate and endoscopic carpal tunnel release using a single 15mm minimally-invasive approach. In one case, arthroscopic scapholunate repair was also required. Six months after the procedure, all patients were reviewed with a clinical examination and a radiological evaluation. The average values for the clinical and radiological outcomes were as follows: pain on VAS 1.5/10; QuickDASH 14.3/100; flexion 90%; extension 90.6%; pronation 95.6%; supination 87.9%; grip strength 90.1%; 2PD test 5.2mm (4-8mm). Five complications occurred: two cases of temporary dysesthesia in the territory of the median nerve and one case of temporary hypoesthesia of the palmar branch of the median nerve, which had all completely recovered; two cases of complex regional pain syndrome type I, which were still active at 6 months. Despite its methodological weaknesses, our study is the only one to describe the technical feasibility of a single 15mm minimally-invasive approach for both internal fixation using a volar locking plate and endoscopic nerve release, with no serious complications. This technique should be added to the surgical toolbox of minimally-invasive procedures for the hand and wrist.

Abstract
Sedimentary dispersal systems with fine-grained beds are common, yet the physics of sediment movement within them remains poorly constrained. We analyze sediment transport data for the best-documented, fine-grained river worldwide, the Huanghe (Yellow River) of China, where sediment flux is underpredicted by an order of magnitude according to well-accepted sediment transport relations. Our theoretical framework, bolstered by field observations, demonstrates that the Huanghe tends toward upper-stage plane bed, yielding minimal form drag, thus markedly enhancing sediment transport efficiency. We present a sediment transport formulation applicable to all river systems with silt to coarse-sand beds. This formulation demonstrates a remarkably sensitive dependence on grain size within a certain narrow range and therefore has special relevance to silt-sand fluvial systems, particularly those affected by dams.

Abstract
As an alternative to amputation of the little finger, we report here seven cases of shortening arthrodesis carried out by resecting the middle phalanx and proximodistal interphalangeal (PDIP) arthrodesis. Our cohort consisted of 6 males and 1 female (58years average age), with a stiff little finger secondary to Dupuytren's disease or trauma. All fingers were approached dorsally; after resection of the middle phalanx and decortication of the subchondral bone, fusion of the remaining phalanges was performed using an intramedullary self-breaking screw-pin. At a mean follow-up of 34.9months, pain decreased significantly (1.4/10 versus 5.4/100 preoperatively), the QuickDASH score improved significantly (33/100 versus 51/100 preoperatively) and all the joints had fused. One patient suffered from cold intolerance. PDIP arthrodesis is an alternative salvage procedure to amputation for multioperated stiff little fingers that does not burn any bridges if it fails.

Abstract
PURPOSE Animal bite injuries are often encountered in daily practice. In particular, these injuries of the upper limbs can result in severe functional impairment. We have performed early debridement of contaminated tissue and primary closure for these injuries. METHODS The subjects consisted of 15 patients (6 males and 9 females) aged 1-91 years (mean 53.6 years) who visited our hospital due to animal bite injuries (dog in 9 patients, cat in 6). The bite site was the forearm in 5 patients and the hand in 10. In the operating room, contaminated tissue was removed, and primary wound closure was performed after irrigation. RESULTS The bite penetrated to the muscle layer in 6 patients, tendon sheath in 5, joint in 1, bone in 1, and involved only the subcutaneous tissue in 3 patients. The mean period until the completion of wound treatment was 19.8 ± 8.4 days. As complications, numbness of finger, metaphalangeal joint contracture and superficial radial nerve injury were observed in each one case. In a patient with bite injury of the palmar and dorsal sides of the thumb reaching the bone, additional debridement was necessary. At the final observation, the visual analog scale was 1.2 ± 1.4, and the Quick Disabilities of the Arm, Shoulder, and Hand score was 9.7 ± 12.2. CONCLUSIONS Debridement to achieve wound closure is indispensable in patients with animal bite injuries of the upper limbs. The results of our study suggest that thorough debridement allows primary closure, even for animal bite injuries.

Abstract
UNLABELLED Advanced stages of Kienböck's disease are treated by several techniques, one of which is Graner's procedure, nearly abandoned nowadays. The results of long-term follow-up of a series of four cases Graner's procedure are presented. Four patients were reviewed with a follow-up of 25years. There were two women and two men mean aged 37years at the time of surgery. Two of them were manual workers. Graner's procedure was the first surgery in three cases and secondary to failure of radius shortening in one case of Stage IIIa. Three patients underwent bone healing and the fourth benefited secondarily from radiocarpal arthrodesis. At maximal follow-up, the mean DASH score was 36.6 and pain assessed by visual analogic scale was 3.25 out of 10; the range of movement was half of the opposite side; the wrist strength was 80.9% of the opposite side. In the three consolidated cases, a spontaneous remodeling of the radiocarpal articular surfaces was noted. Graner's procedure is logical as it aims at creating a new radiocarpal articulation, either by the fusion of the lunate with the capitate (Graner I) or by replacing the lunate with the head of the capitate (Graner II and III). However, this old procedure should no longer be one of the surgical procedures for Kienböck disease due to its drawbacks: necrosis or non-union of the head of the capitate, necessity to perform a wrist fusion in the long-term and side effects of bone graft harvesting. LEVEL OF EVIDENCE II. Retrospective study.

Abstract
The treatment of ulnar nerve compression at the elbow remains controversial. No single technique has yet proven its superiority. We describe a technique combining the advantages of the mini-invasive approach with those of transposition. We present the results of 30 patients, of mean age 52 years, who underwent anterior subcutaneous transposition of the ulnar nerve using a mini-invasive approach with a follow-up of more than six months. The incision measures 3 cm. The results were evaluated by measuring pain intensity, quick disabilities of the arm shoulder and hand (DASH), grip strength and pinch, and McGowan score, pre- and post-operatively. All parameters were improved post-operative. The mean pain score went from 5.5 to 4, the quick DASH from 48 to 38, mean grip strength from 28 to 31 kg, and mean pinch strength from 4.7 to 6.4 kg. The McGowan score was also improved; pre-operatively, there were 16 patients at stage III, seven patients stage II, seven patients stage I, and post-operatively there was one patient stage III, three patients stage II, 16 patients stage I, and 10 patients stage 0. Analysis of our series shows that a 3 cm incision without endoscopy allows subcutanous transposition, with results at least as good as those with other techniques. The advantages of our technique are that it is easy, has a limited approach, preserves blood supply, allows placement of the nerve in a favourable environment, and decreases nerve stretching during elbow flexion.

Abstract
Zinc finger nucleases (ZFN), which are artificial restriction enzymes consisting of an engineered zinc-finger domain (ZF) and an endonuclease domain, can be used for the induction of site-directed mutation and the efficient generation of gene knockout animals. However, the repeated construction of various ZFN sequences is both expensive and time consuming. In this study, we attempted to establish a novel method for inexpensive and rapid ZFN construction. First, we constructed ZFN against mouse Rosa26 and original mouse Gli3 gene loci using short PCR primer sets (>30 bp), which contained 21 bp of the ZF recognition helix for a specific DNA triplet. We prepared 18 sets of such primers and PCR was performed using one of these primer sets and the partial ZF sequence as a template, which was obtained from the first to second DNA recognition helix of mouse Zif268. The PCR products were joined by overlap-PCR and nested PCR, and then inserted into a vector coding the endonuclease domain of FokI nuclease. By these steps, we successfully synthesised intended ZFN vectors containing 4 to 6 fingers. Next, we evaluated the functions of constructed ZFN. The mRNA of constructed ZFN were transcribed in vitro and injected into the cytoplasm of C57BL/6N zygotes. After 24 h of culture, 2-cell stage embryos were subjected to genomic PCR of the target locus, and the PCR products were directly sequenced. When ZFN mRNA for mouse Rosa26 was injected, 3- to 146-bp deletions were detected in 92.8% of injected embryos. This result was almost the same as previously reported for ZFN, indicating that our novel construction method can synthesise functional ZFN, which work as a site-directed nuclease, and that efficiency was comparable with those constructed by conventional PCR methods using long oligonucleotide sets (60 bp).

Abstract
Recent studies have shown the critical roles of fibroblast growth factors (FGFs), including FGF8 produced by oocytes, in regulating follicular development. However, the expression and regulation of the FGF gene family, which consists of 22 ligands and 4 receptors, in the mouse ovary have not been well understood. The aim of the present study was to assess the expression and regulation of FGF ligands and receptors in the mouse ovary. Transcript levels of FGF ligands and receptors in immature (3-week-old) and adult (7- to 8-week-old) ovaries as well as other tissues of B6/DBA2F1 mice were analysed with RT-PCR. Furthermore, expression levels of FGF receptors in cumulus cells (CC) and mural granulosa cells (MG) before and after equine chorionic gonadotropin (eCG) treatment were determined with RT-quantitative PCR. Among 21 FGF ligands examined, 12 and 9 transcripts were detectable in immature and adult ovaries, respectively. More FGF ligands were detected in ovary, testis, heart, and brain compared to other tissues, including liver and spleen. Transcripts of all 4 FGF receptors (Fgfr1–4) were detectable in both immature and adult ovaries. Expression levels of Fgfr1 and Fgfr2 were significantly higher in MG compared with CC before and after the eCG treatment. Levels of Fgfr4 were comparable between MG and CC before the eCG treatment, but became significantly different with higher expression levels in MG after the eCG treatment. Fgfr3 transcripts were barely detectable in CC and MG. Overall levels of Fgfr1 in granulosa cells (CC and MG) were downregulated by eCG treatment, whereas those of Fgfr2 and Fgfr4 were upregulated. In summary, many FGF ligands are expressed, at least in mRNA levels, in mouse ovaries. Moreover, the expression levels of Fgfr transcripts in granulosa cells are dynamically regulated during follicular development.

Abstract
Background: The authors have focused their attention to the radiological durability of cervical sagittal alignment after anterior cervical discectomy and fusion (ACDF) using autologous bone grafting. Materials and Methods: Among the patients who underwent ACDF with trans-unco-discal (TUD) approach between 1976 and 1997, 22 patients (16 males and 6 females) made return visits for a clinical evaluation. Patients with trauma or previously treated by anterior cervical fusion or by posterior decompression were excluded from the present study. Clinical evaluation included adjacent segment degeneration (ASD), osseous fusion, local angle at the fused segments and C2-7 angle of cervical spine. Results: The duration after ACDF ranged from 13 to 34 years with an average of 21.3 ± 7.0 years. A single level fusion was done on 8 patients, 2 levels on 11 patients, 3 levels on 2 patients, and 4 levels on 1 patient. Imaging studies indicated that 12 of the 22 patients (54.5%) were graded as having symptomatic ASD. Osseous bony fusion at ACDF was recognized in all cases. None of the patients demonstrated kyphotic malalignment of the cervical spine. Average degrees of local angle at the fused segments and the C2-7 angle were 7.06 and 17.6, respectively. Statistical analysis indicated a significant relationship between the local at the fused segments and C2-7 angles. Conclusions: Sagittal alignment of the cervical spine was durable long after ACDF when the local angle at the fused segments was well stabilized.

Abstract
INTRODUCTION It is usual to stop the intake of oral anticoagulants (anti-vitamin K) before surgery. Some authors have shown that during minimal surgery, the relay with low molecular weight heparin (LMWH) may lead to more thromboembolic complications. We present a prospective comparative study while evaluating the results of stopping or continuing anticoagulants in the surgery for carpal tunnel syndrome. MATERIAL AND METHODS Our series included 21 patients (24 hands) taking anticoagulants on a long-term basis. For the first nine patients (group I), treatment with anticoagulants was stopped before the surgery. For the following 12 patients (group II), treatment with anticoagulants was not interrupted. The evaluation was based on the measurement of pain (VAS), functional score of the Quick D.A.S.H. and grip strength (Jamar®) and search for a haematoma or thromboembolism). RESULTS The pain decreased by 3.5 points in both groups. The Quick D.A.S.H. decreased by 19.9 and 27.7 points in groups I and II, respectively. The average grip strength decreased by 2.5 kg in group I and increased by 3.8 kg in group II. A subcutaneous haematoma that got healed by itself was observed in group II. We did not observe any thromboembolic complications. DISCUSSION In conclusion, it seems pointless to stop anticoagulants before surgical treatment of carpal tunnel. The first reason is that continuing anticoagulants does not result in a bleeding risk. The second reason is that this approach removes the theoretical risk of thromboembolic complications during a poorly monitored relay.

Abstract
We investigated a method for measuring deformation and strain distribution in a multiscale range from nanometers to millimeters via in situ FE-SEM observations. A multiscale pattern composed of a grid as well as random and nanocluster patterns was developed to measure the localized deformation at the specimen surface. Our in situ observations of a carbon fiber-reinforced polymer matrix composite with a hierarchical microstructure subjected to loading were conducted to identify local deformation behaviors at various boundaries. We measured and analyzed the multiscale deformation and strain localizations during various stages of loading.

Abstract
The complex kinase Cdk-activating kinase (CAK) consists of the catalytic subunit Cdk7, regulatory subunit Cyclin H, and assembly factor Mat1. The CAK is essential for maturation-promoting factor (MPF) activation by phosphorylating threonine 161 (T161) of Cdc2 in mitosis. Although it is known that meiotic resumption of oocytes is regulated by MPF activity, the role of CAK in meiosis is still unclear. In the present study, we attempted to confirm the involvement of CAK in meiotic resumption of porcine immature oocyte. Cumulus–oocyte complexes (COC) were collected from antral follicles of gilts and cultured up to 48 h in TYH medium containing 20% porcine follicular fluid, 3.2 mg/mL of BSA, and 1.0 IU mL–1 of pregnant mare serum gonadotropin. The T161 phosphorylation level of Cdc2 in cultured oocytes was analysed by Western blot analysis. The transcripts were collected from noncultured or cultured oocytes, and Cdk7, Cyclin H, and Mat1 expression were detected by RT-PCR. Overexpression of Cdc2 or inhibition of Cdk7, Cyclin H, and Mat1 during oocyte maturation was performed by microinjection of mRNA or antisense RNA into ooplasm of immature COC and verified by Western blot or semiquantitative RT-PCR. Maturation-promoting factor kinase activity was assayed by Histone H1 kinase activity assay. Statistical analyses in this study were carried out by Student’s t-test. The T161 phosphorylation of Cdc2 was found during the culture period from 18 h to 48h, which was after germinal vesicle breakdown (GVB). Overexpression of Cdc2 increased the incidence of GVB at 18 h, but overexpression of mutant Cdc2 (replaced T161 by alanine) had no influence on GVB. These results indicate that T161 phosphorylation of Cdc2 is important for meiotic resumption. Next, we attempted to confirm the CAK function during oocyte maturation. Transcripts of Cdk7, Cyclin H, and Mat1 were detectable throughout the culture period. Inhibition of Cdk7 and Cyclin H caused a decrease in T161 phosphorylation and MPF activity, and the incidence of GVB was significantly lower than in nontreated oocytes. In contrast, Mat1-inhibited oocytes resumed meiosis and developed to the metaphase II stage, and the incidence was not different between Mat1-inhibited oocytes and nontreated oocytes. These results suggest that Cdk7 and Cyclin H are working as CAK and activate Cdc2 by T161 phosphorylation, although Mat1 is dispensable during oocyte maturation.

Abstract
Abstract
Purpose: Signal attenuation of diffusion-weighted magnetic resonance images (DWI) in vivo with high b-values is sometimes non-linear when plotted with a semilogarithmic function, but it fits well with the biexponential equation, Sb/S0=f1exp(bD1) + (1-f1)(bD2). Others have indicated that the fast and slow component fractions (f1, 1-f1) of the apparent diffusion coefficients (D1, D2) can be derived by biexponential fitting, and that these fractions correspond to actual diffusion components in the extra-and intracellular space. Here, we investigated the clinical value of DWI for breast screening by performing multi b-factor DWI on healthy volunteers and patients. We then analyzed signals by fitting them with the biexponential equation and compared the fitting parameters of breast lesions.
Patients and methods: This study was approved by our center's institutional review board and all patients and volunteers gave their informed consent. We analyzed data from eight healthy females (controls) and 80 female patients with a total of 100 breast tumors (42 benign and 58 malignant). We performed DWI using 12 and 6 b-values for the controls and patients up to a maximum b-value of 3500 sec/mm2.
Results: We identified the DWI signal attenuation features of the normal mammary gland, and of benign and malignant tumors [Figure1]. The DWI signal attenuation was similar between some proliferative benign tumors and malignancies. A comparison of the parameters derived from biexponential fitting revealed a significant difference in f1 between noninvasive and invasive ductal carcinoma [Figure 2]. Conclusion: The biexponential fitting parameters might reflect the features of tumor cellularity. Thus, to distinguish malignant from benign breast tumors only by DWI is difficult due to the pathological diagnosis that rather emphasizes cell configuration or shape rather than cellularity. Nevertheless, our findings will help to understand why malignant tumors present as high signal intensity in DWI.

Abstract
BACKGROUND Scant evidence has been reported on the evaluation of quality-of-life (QOL) in patients who had undergone surgical treatment due to pelvic floor prolapse including cystocele. The aim of this study is to evaluate the impact of surgical intervention on patients' QOL before and after surgery. METHODS Between 1997 and 2007, 135 patients (median age: 66.6 years) with pelvic floor prolapse including cystocele underwent bladder neck suspension with anterior/posterior colporrhaphy. The follow-up period was 39.6 months. Seventy-two patients (53 %) had urinary incontinence. The cystocele was graded as mild (grade 2), moderate (grade 3), and severe (grade 4) in 35, 60, and 40, respectively, according to the Baden-Walker classification. A urodynamic study was performed in 69 patients (51 %) who had obstructive symptoms with 100 ml or more of postvoid residual urine. Postoperative QOL was longitudinally assessed in 114 patients by scoring three disease-specific items (sensation of vaginal bulging, obstructive symptoms, urinary incontinence), and one overall health-related QOL (HR-QOL), and compared with corresponding baseline scores. RESULTS A longitudinal study demonstrated that a significant improvement in these symptoms was sustained at a median follow-up of 62.2 months. HR-QOL was significantly associated with vitality assessed by SF 36 (p = 0.036). Multivariate analysis revealed that update urinary incontinence, pre-operative HR-QOL was independent prognostic factors for predicting postoperative patient's satisfaction. CONCLUSIONS Although surgical repair of pelvic floor prolapse can achieve acceptable results with intermediate-term durability as well as improving the QOL, preoperative patients' HR-QOL may be considered in the decision making process for treatment.

Abstract
BACKGROUND Ras association domain family 1A (RASSF1A) is a tumor suppressor that regulates the cell cycle, apoptosis, and microtubule stability. The association between the methylation levels of RASSF1A and the prognosis of clear-cell renal cell carcinoma (CCRCC) remains unclear. Therefore, we investigated this relationship to determine the prognostic value of RASSF1A methylation levels for CCRCC. PATIENTS AND METHODS The study comprised 179 Japanese patients who underwent radical or partial nephrectomy for CCRCC. The methylation level of 5' CpG islands in the RASSF1A was evaluated using combined bisulfite restriction analysis and bisulfite sequencing. RESULTS High levels of methylation in the RASSF1A promoter were significantly more frequent in grade 3 compared with grade 1 or 2 tumors (P = 0.028) and in patients with stage III or IV compared with patients with stage I or II (P = 0.043). Patients with high methylation levels had a significantly less favorable prognosis compared with those with low methylation levels (P = 0.040). Higher methylation levels were independently associated with a poor prognosis following multivariate analysis (P = 0.0053). CONCLUSION These results indicate that quantitative promoter methylation levels of the RASSF1A gene may be a useful marker to predict the prognosis of CCRCC.

Abstract
We studied the cytotoxic effect of an organic arsenical compound, phenylarsine oxide (PAO) on an acute promyelocytic leukemia (APL) cell line (NB4) and an As2O3-resistant NB4 subline (NB4/As). Cell growth was inhibited by 50% (IC50) upon 2-day treatment with As2O3 or PAO at 0.54 and 0.06 microM, respectively in NB4 cells (P = 0.025), and 2.80 and 0.08 microM, respectively in NB4/As (P = 0.030). 0.1 microM PAO increased the proportion of hypodiploid cells (50.3%) by a greater degree than the same dose of As2O3 (3.8%) in NB4 cells. In NB4 cells, 0.1 microM PAO reduced the mitochondrial transmembrane potential (20.5% in a PI(negative)-Rhodamine123(low) fraction) by a greater degree than 1 microM As2O3 (7.1%). Western blotting showed that 0.1 microM PAO downregulated the expression of both Bcl-2 and Bcl-X(L) proteins, whereas I microM As2O3 downregulated only Bcl-2 expression. These results suggest that the cytotoxic effect of PAO on an APL cell line and As2O3-resistant subline is significantly higher than that of As2O3. PAO-induced apoptosis seems to be related to the activation of the mitochondrial pathway and downregulation of both Bcl-2 and Bcl-X(L). PAO is a considerable agent for relapsed/refractory APL and for purging APL cells following stem cell transplantation.

Abstract
Of 103 patients who underwent varicocelectomies, 87 underwent all the diagnostic methods: color Doppler ultrasonography (DOP), scrotal deep body temperature (DBT), and scrotal scintigraphy (SSG). Total motile sperm (TM) was calculated. The positivities of DOP, DBT, and SSG were 67, 51, and 90%, respectively. In the patients <30 years old, TM increased in the DBT-positive group. In older patients, positive for DBT indicated poor improvement of TM, whereas positive for DOP indicated better response in the group. Patients older than 30 years and positive for DBT, but not DOP, should be counseled directly to receive intrauterine insemination or in vitro fertilization/intracytoplasmic sperm injection.

Abstract
The primary objective of this study was to investigate the tolerability, efficacy and pharmacokinetic profile of gemtuzumab ozogamicin (GO) in patients with relapsed and/or refractory CD33-positive acute myeloid leukemia (AML). Patients received 2-h infusions of GO twice with an interval of approximately 14 days. Tolerability was assessed using the National Cancer Institute Common Toxicity Criteria Version 2.0. Samples for pharmacokinetics were taken on day 1 and day 8 of the first treatment cycle. The dose was increased stepwise and, in each cohort, patients were treated at the same dose. Forty patients, median age 58 years (range 28-68) were treated; 20 and 20 patients were enrolled to the phase I and II parts, respectively. In the phase I part, dose-limiting toxicities (DLTs) were hepatotoxicities, and the recommended dose was established as 9 mg/m2 given as two intravenous infusions separated by approximately 14 days. The pharmacokinetic study revealed that Cmax and AUC were equivalent to those of non-Japanese patients. In the phase II part, complete remission was observed in 5 patients, and one patient had complete remission without platelet recovery. Four of these 6 in remission and one in the phase I are long-term survivors (alive for at least 44 months). GO is safe and effective as a single agent among Japanese CD33-positive AML patients. Remission lasted longer in a subset of patients than in non-Japanese patients in earlier studies. Further studies of this agent are warranted to establish standard therapy.

Abstract #5153
Background: Radiofrequency ablation therapy (RFA) is one of the most minimally invasive approaches for the treatment of hepatic cancers and other solid malignancies. The aim of this study is to assess the safety and local controllability of RFA against breast cancer.
 Patients and Methods: A total of 100 pts with localized early breast cancer were enrolled. Ductal spreading and/or daughter nodules were preoperatively checked with mammography, ultrasound and MRI. Tumor size was 0.5-2.0cm (median 1.5cm). LeVeen system and Cool-tip RF system was used in 5 pts and 95 pts respectively. One session of RFA was applied to 96 pts, 2 sessions to 4 pts. To avoid skin burn, 5% glucose was injected subcutaneously just above the tumor and the skin was cooled during RFA. After completing RFA, temperatures along the needle tract were measured at 1 cm intervals in 89 pts. All pts underwent cytological and MR-imaging study 3-4 weeks after operation, and received adjuvant radiotherapy (50Gy) to the breast.
 Results: RFA heated the tumors up to over 60° in 1 pt, 70° in 4 pts, 80° in 21 pts, 90° in 51 pts, and 100° in 13 pts. Skin burn was found in 2 pts over the tumor, and 1 pt at the grounding pads. No major side effects except for skin burn were found. Postoperative cytological and imaging study showed complete ablation of all the target tumors. No pts developed local and distant recurrence for 16-54 months (median 31 months).
 Discussion: Our RFA procedures can offer good local control without serious adverse events to breast cancer patients.

Abstract
Retrospective analysis was done to evaluate concurrent chemoradiotherapy (CCRT) using chemotherapeutic agents judged to be sensitive by histoculture drug response assay (HDRA) for non-small cell lung cancer (NSCLC). We treated 21 NSCLC patients with CCRT using senstivie agents judged by HDRA from 1999 to 2004. Objective response was evaluated in 20 patients. They were consisted of 1 complete response (CR) case, 18 partial response (PR) cases, and 1 stable disease (SD) case. The response rate was 95%. Ten cancer related deaths were observed during 816 +/- 861 (60-2,780) days follow-up. Median survival time was 604 days. One- and 5-year survival rates were 73.9% and 40.3%, respectively. In conclusion, HDRA may improve efficacy of CCRT for NSCLC.

Abstract
AIMS Despite the growing literature on workplace tobacco control policies, very few studies have evaluated the role of smoking cessation programme as one of these policies in a university setting. We aimed to investigate the efficacy of intensive cessation programme delivered in a group format using nicotine patch therapy and internet mailing supports for our university employees. METHODS From January 2003, we conducted the group therapy programme for smoking cession seven times in Okayama University, Japan. This programme consisted of nicotine patch therapy and on-line supporting system. Smoking status was regularly assessed by direct interviews. RESULTS A total of 102 employees were enrolled in this programme, of whom 101 initiated their smoking cessation. One hundred participants (99%) received nicotine patch therapy, and its toxicities were generally mild. Of the 94 employees who could be follow-up for a year after the cessation, 50 (53%) sustained abstinence for a year. Multivariate analysis revealed that writing and sending e-mail messages within the first 1 week were significant factors affecting long-term cessation. The type of position also affected the cessation rate. CONCLUSION This study suggests that our programme in a university setting seems to be effective mainly because of peer-supports among the participants through regular face-to-face meetings and their own mailing supports.
