Abstract
AIM Intersphincteric resection (ISR) is an advanced anus-preserving operation for treating low rectal cancer while avoiding colostomy. High-resolution anorectal manometry (HR-ARM) allows objective and accurate evaluation of anal function. However, correlations between anal function after ISR and HR-ARM parameters are unknown. The aim of the study was to evaluate HR-ARM for objective evaluation of anal function after ISR. METHOD A total of 81 patients who underwent ISR at our hospital between October 2014 and March 2016 were identified from our prospectively collected database and electronic medical records. Of these, 68 patients who had been evaluated using HR-ARM both before and after ISR were included in the study. Faecal incontinence (FI) was assessed by Wexner score. Multivariate analysis was performed to determine risk factors for severe FI after ISR. RESULTS Maximum resting pressure (MRP) (P < 0.001) and maximum squeeze pressure (P = 0.04) were significantly lower after ISR, and MRP (P < 0.001) and maximum squeeze pressure (P = 0.02) were significantly lower after total (or subtotal) ISR than after partial ISR. The overall incidence of severe FI after ISR was 18% (12/68), and a high pressure zone before ISR ≤ 3 cm (P = 0.007) and MRP before ISR > 60 mmHg (P = 0.02) were independently associated with an elevated incidence of severe FI after ISR. Decreased preoperative MRP also correlated with severe FI after ISR (P = 0.008). CONCLUSION HR-ARM is reliable for the evaluation of anal function after ISR, and the high pressure zone and MRP may be useful preoperative predictors of severe FI after ISR.

Abstract
INTRODUCTION Hepatocyte transplantation is a promising alternate for the treatment of hepatic diseases. Hypothermic preservation of isolated human hepatocytes is potentially a simple and convenient strategy to provide on-demand hepatocytes in the quantity sufficient and the quality required for biotherapy. Isolated fresh hepatocytes include damaged cells that are also early apoptotic cells, which is not ideal for hepatocyte transplantation. However, this does not reflect cell viability, although it is considered that it adversely affects cell survival after transplantation. We aimed to harvest these hepatocytes and filter the apoptotic cells using a magnetic method to provide a transplantation source. MATERIALS AND METHODS Rat hepatocytes were isolated from caudate lobes using manual enzymatic perfusion. The hepatocyte yield was 5.3 ± 0.66 × 109 cells/g of liver tissue, with a viability of 82.3 ± 3.5%. Two samples of hepatocytes were freshly isolated, one using the magnetic method, and the other without. The magnetic method was performed using DynaMag-15 Magnet, and Annexin V Antibody was used on the early apoptotic cells. We evaluated the viability and plate efficiency of the cells after 24 hours at 37°C. Hepatocytes were isolated using cell separation method, and 30 × 106 cells were mixed with 1.0 mL of Dulbecco's Modified Eagle's Medium (DMEM) and directly injected into the spleen of Lewis rats (150-250 g) using 24-gauge needles. Blood samples were collected on days 0, 3, 7, and 14, and the blood albumin level was measured using enzyme-linked immunosorbent assay (ELISA):G1, control (medium injection); G2, fresh hepatocyte transplant using the magnetic method; and G3, fresh hepatocyte transplant without the magnetic method. RESULTS The viability was 84.9 ± 2% for fresh hepatocytes and 80.7 ± 1.2% for hepatocytes isolated using the magnetic method. The magnetic method does not damage the cells (73.5 ± 2% vs 35.2 ± 2% after 24 hours), preserving hepatocyte. The albumin level accepted significantly increased in the magnet-treated group compared with the nonmagnet group. Simultaneously, the spleen in which these hepatocytes were transplanted could be used to observe the hepatocytes; the cells were transplanted 14 days later, and the magnet-treated group had significantly higher levels of hepatocytes than the nonmagnet group. CONCLUSION We developed an effective technique for hepatocyte isolation for short-term preservation. As a result, we believe that transplantation not only improves the cell transplantation effect but also allows the cells to be stored efficiently using the magnetic method. These results demonstrate the usefulness of hepatocyte hypothermic preservation for cell transplantation.

Abstract
SummaryThe hemostatic abnormality in 18 patients with adult T cell leukemia (ATL) was studied. Activated partial thromboplastin time (APTT) was slightly prolonged and prekallikrein activity was markedly low in these patients. The leukemic cell homogenate from these patients prolonged the recalcification time (RCT) of normal plasma; homogenates containing more than 3 ×103 cells/μi prolonged it, although a lower cell concentration shortened it. The crude anticoagulant fraction from the gel filtration, with a molecular weight of about 34,000, prolonged RCT. The crude anticoagulant did not affect prothrombin time (PT), thrombin activity or activated X activity at any concentration, but prolonged the contact activation test, inhibited the activation of prekallikrein and prolonged RCT of Fletcher trait, Fitzgerald trait and F XII deficient plasma. These effects of ATL cell homo-genate were stronger on platelet poor plasma than on platelet rich plasma. Although ATL cells had low procoagulant activity, increase of leukemic cells made anticoagulant activity predominant, might be the cause of hemostatic abnormality or amplify the bleeding tendency in patients with ATL.

Abstract
Swine influenza viruses (SIVs) are important not only for pig farming, but also for public health. In fact, pandemic A(H1N1) 2009 viruses [A(H1N1)pdm09] were derived from SIVs. Therefore, timely characterization of locally circulating SIVs is necessary for understanding the global status of SIVs. To genetically characterize SIVs circulating in Japanese pig populations, we isolated 24 SIVs of three subtypes (17 H1N1, four H1N2 and three H3N2 strains) from 14 pig farms in Japan from 2013 to 2016. Genetic analyses revealed that the haemagglutinin (HA) and neuraminidase (NA) genes of the 17 H1N1 and the HA gene of one H1N2, A/swine/Aichi/02/2016 (H1N2), SIVs belonged to the A(H1N1)pdm09 lineage. More importantly, all of the remaining six gene segments (i.e., PB1, PB1, PA, NP, M and NS) of the 24 SIVs, regardless of the HA and NA subtype, were also classified as belonging to the A(H1N1)pdm09 lineage. These results indicate that gene segments of A(H1N1)pdm09 lineage are widely distributed in SIVs circulating in Japanese pig populations In addition, the NA gene of A/swine/Aichi/02/2016 (H1N2) shared less than 88.5% nucleotide identity with that of the closest relative A/swine/Miyagi/5/2003 (H1N2), which was isolated in Japan in 2003. These results indicate the sustained circulation of classical H1N2-derived SIVs with remarkable diversity in the NA genes in Japanese pig populations. These findings highlight the necessity of both intensive biosecurity systems and active SIV surveillance in pig populations worldwide for both animal and public health.

Abstract
MIB-1 is a cell proliferation marker and has previously been investigated as a diagnostic or prognostic indicator of malignancy. Previous studies have investigated MIB-1 index and clinicopathological factors in relation to prognosis of patients with esophageal cancer, with conflicting results. The aim of this study is to assess the prognostic significance of MIB-1 index in patients with thoracic esophageal squamous cell carcinoma. A total of 78 patients who underwent R0-esophagectomy for thoracic esophageal squamous cell carcinoma were enrolled in this study. Preoperatively, 29 patients underwent chemotherapy, six underwent chemoradiotherapy, and the remaining did not undergo any preoperative therapy. The MIB-1 labeling index was reported by counting 500 tumor cells in the hot spots of nuclear labeling. Correlations between MIB-1 index, clinicopathological factors, and relapse-free survival (RFS) were investigated. The mean MIB-1 index was 39.3 ± 21.0 (range: 0-91.3). There was no significant correlation between clinicopathological factors and MIB-1 index in the study patients, irrespective of whether they underwent preoperative therapy. Univariate analysis revealed no significant association between MIB-1 index and RFS. However, depth of tumor invasion, lymph node metastasis and stage, all showed a significant correlation to RFS. Multivariate analysis of RFS revealed that stage was the only significant factor. Conversely, MIB-1 index was not significantly related to RFS (p = 0.41). In conclusion, MIB-1 index is unlikely to be a significant prognostic indicator for esophageal cancer.
