Abstract
Parallel cascade selection molecular dynamics (PaCS-MD) is an enhanced conformational sampling method conducted as a "repetition of time leaps in parallel worlds", comprising cycles of multiple molecular dynamics (MD) simulations performed in parallel and selection of the initial structures of MDs for the next cycle. We developed PaCS-Toolkit, an optimized software utility enabling the use of different MD software and trajectory analysis tools to facilitate the execution of the PaCS-MD simulation and analyze the obtained trajectories, including the preparation for the subsequent construction of the Markov state model. PaCS-Toolkit is coded with Python, is compatible with various computing environments, and allows for easy customization by editing the configuration file and specifying the MD software and analysis tools to be used. We present the software design of PaCS-Toolkit and demonstrate applications of PaCS-MD variations: original targeted PaCS-MD to peptide folding; rmsdPaCS-MD to protein domain motion; and dissociation PaCS-MD to ligand dissociation from adenosine A2A receptor.

Abstract
BACKGROUND It was reported that rikkunshito (TJ-43) improved the cisplatin-induced decreases in the active form of ghrelin in plasma; however, other effects on gastrointestinal hormones have not been investigated. AIM To investigate the effects of TJ-43 on peripheral levels of incretin hormones, including gastric inhibitory polypeptide (GIP) and glucagon-like polypeptide-1 (GLP-1), in humans and rats. METHODS Patients were divided into two groups, namely patients who received TJ-43 immediately following surgery [TJ-43(+) group] and those who received TJ-43 on postoperative day 21 [TJ-43(-) group], and the plasma levels of active GIP and active GLP-1 were assessed. In animal experiments, rats were treated with TJ-43 [rat (r)TJ-43(+) group] or without [rTJ-43(-) group] by gavage for 4 wk, and the plasma active GIP and active GLP-1 levels were measured. The expression of incretin hormones in the gastrointestinal tract and insulin in the pancreas were investigated by immunohistochemistry. Furthermore, the cyclic adenosine monophosphate activities were assessed in pancreatic tissues from rats treated with or without TJ-43 in vivo, and the blood glucose levels and plasma insulin levels were measured in rats treated with or without TJ-43 in oral glucose tolerance tests. RESULTS In humans, the active incretin hormone levels increased, and values were significantly greater in the TJ-43(+) group compared those in the TJ-43(-) group. In rats, the plasma active incretin levels significantly increased in the rTJ-43(+) group compared with those in the rTJ-43(-) group. GIP and GLP-1 expressions were enhanced by TJ-43 treatment. Moreover, plasma insulin levels increased and blood glucose levels were blunted in the rTJ-43(+) group. CONCLUSION The results show that TJ-43 may be beneficial for patients who undergo pancreatic surgery.

Abstract
BACKGROUND/AIM Cytoglobin (Cygb), a protein involved in cellular oxygen metabolism and protection, has garnered attention owing to its potential role in the initiation and progression of cancer, particularly colon cancer (CC). This study investigated the expression and significance of Cygb in CC. PATIENTS AND METHODS This study included 145 patients who underwent R0 surgery for CC (clinical stage II/III) at our institution between January 2007 and December 2014. Immunohistochemical analysis was performed to evaluate the Cygb expression patterns in CC tissues. Additionally, the correlation between Cygb expression levels and the clinicopathological characteristics of patients with CC was investigated. RESULTS Colon cancer tissues were categorized into high-expression (95 cases) and low-expression (50 cases) groups. Cygb was highly expressed in well-differentiated cases, whereas its expression decreased in poorly differentiated cases. No significant differences in other clinicopathological factors were observed between the two groups. Cygb expression had no significant effect on recurrence-free survival or overall survival. CONCLUSION This study contributes to the growing understanding of Cygb expression and its significance in CC. The expression of Cygb in CC was found to be unrelated to the recurrence rate and prognosis, but showed a correlation with differentiation status.

Abstract
BACKGROUND Cerium ions promote osteoclastogenesis and activate bone metabolism, while cerium oxide nanoparticles exhibit potent anti-inflammatory properties, making them promising for biomedical applications. OBJECTIVE The purpose of this study was to develop and evaluate a synthesis method for sustained-release cerium-ion bioceramics containing apatite. Substituted apatite was found to be an effective biomaterial. METHODS Cerium-containing chlorapatite was synthesized using a mechanochemical method employing dicalcium phosphate, cerium chloride heptahydrate, and calcium hydroxide as raw materials. The synthesized samples were characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and Raman spectroscopy. RESULTS Cerium chlorapatite was successfully synthesized in the 10.1% and 20.1% samples. However, at Ce concentrations higher than 30.2%, the samples consisted of three or more phases, indicating the instability of a single phase. CONCLUSION The method used in this study was found to be more efficient and cost-effective than the precipitation method for producing substituted apatite and calcium phosphate-based biomaterials. This research contributes to the development of sustained-release cerium-ion bioceramics with potential applications in the field of biomedicine.

Abstract
BACKGROUND/AIM We investigated the postoperative treatment status for diabetes mellitus and perioperative HbA1c levels in patients with diabetes mellitus and examined the effects of clinical factors on the remission of diabetes mellitus. PATIENTS AND METHODS In this study, 126 patients with gastric cancer were considered to have diabetes mellitus preoperatively, of whom 79 were treated with oral antidiabetic drugs and/or insulin treatment. We compared diabetic treatment status and HbA1c values between the preoperative and postoperative periods in patients who underwent gastrectomy and examined the effects of clinical factors on improving diabetes mellitus. RESULTS Of the 79 patients treated preoperatively for diabetes mellitus, 34 (43%) discontinued all medications for diabetes mellitus and for 37 (47%) the therapeutic dose was reduced or switched from insulin to oral antidiabetic drugs. Total gastrectomy was an independent factor for remission of antidiabetic treatments after gastrectomy. Concerning HbA1c levels, only the absence of preoperative insulin use was an independent factor for improvement. However, reconstruction was not a significantly correlated factor for the improvement of postoperative HbA1c levels and reduction of antidiabetic medications after distal gastrectomy. CONCLUSION Almost all patients discontinued or had their dose of antidiabetic medications reduced after gastrectomy in clinical practice, and special attention should be paid in the management methods for diabetes mellitus in patients who underwent total gastrectomy for gastric cancer.

Abstract
BACKGROUND Rikkunshito (TJ-43) relieves gastrointestinal disturbance by increases in the levels of acylated ghrelin.
AIM To investigate the effects of TJ-43 in patients undergoing pancreatic surgery.
METHODS Forty-one patients undergoing pylorus-preserving pancreaticoduodenectomy (PpPD) were divided into two groups; patients took daily doses of TJ-43 after surgery or after postoperative day (POD) 21. The plasma levels of acylated and desacylated ghrelin, cholecystokinin (CCK), peptide YY (PYY), gastric inhibitory peptide (GIP), and active glucagon-like peptide (GLP)-1 were evaluated. Oral calorie intake was assessed at POD 21 in both groups. The primary endpoint of this study was the total food intake after PpPD.
RESULTS The levels of acylated ghrelin were significantly greater in patients treated with TJ-43 than those in patients without TJ-43 administration at POD 21, and oral intake was significantly increased in patients treated with TJ-43. The CCK and PYY levels were significantly greater in patients treated with TJ-43 than those in patients without TJ-43 treatment. Furthermore, the GIP and active GLP-1 levels increased and values at POD 21 were significantly greater in patients treated with TJ-43 than those in patients without TJ-43 administration. Insulin secretion tended to increase in patients treated with TJ-43.
CONCLUSION TJ-43 may have advantages for oral food intake in patients in the early phase after pancreatic surgery. Further investigation is needed to clarify the effects of TJ-43 on incretin hormones.

Abstract
BACKGROUND/AIM Although cholesterol is an important indicator of nutritional status, it is also involved in cancer progression. In this study, we investigated the clinical significance of the dynamics of perioperative total cholesterol (T-Cho) levels in patients with gastric cancer (GC). PATIENTS AND METHODS A total of 212 patients with pathological stage II/III disease who underwent gastrectomy between 2004 and 2020 were enrolled in this retrospective study. The preoperative and postoperative serum T-Cho levels were measured in these patients. RESULTS Increased serum T-Cho levels were significantly correlated with low preoperative serum albumin levels (p<0.001). Patients with increased serum T-Cho levels after surgery had significantly lower overall and recurrence-free survival rates (p=0.030 and p=0.013, respectively; log-rank test). Cox proportional hazards model revealed that increased serum T-Cho levels (p=0.040), advanced pathological stage (p<0.001), and the provision of adjuvant chemotherapy (p=0.006) were independent prognostic factors for recurrence-free survival in patients with GC. CONCLUSION Increased serum T-Cho levels after gastrectomy may be an independent prognostic factor in patients with GC.

Abstract
Ligamentum flavum (LF) hypertrophy is a major cause of lumbar spinal canal stenosis. Although mechanical stress is thought to be a major factor involved in LF hypertrophy, the exact mechanism by which it causes hypertrophy has not yet been fully elucidated. Here, changes in gene expression due to long-term mechanical stress were analyzed using RNA-seq in a rabbit LF hypertrophy model. In combination with previously reported analysis results, periostin was identified as a molecule whose expression fluctuates due to mechanical stress. The expression and function of periostin were further investigated using human LF tissues and primary LF cell cultures. Periostin was abundantly expressed in human hypertrophied LF tissues, and periostin gene expression was significantly correlated with LF thickness. In vitro, mechanical stress increased gene expressions of periostin, transforming growth factor-β1, α-smooth muscle actin, collagen type 1 alpha 1, and interleukin-6 (IL-6) in LF cells. Periostin blockade suppressed the mechanical stress-induced gene expression of IL-6 while periostin treatment increased IL-6 gene expression. Our results suggest that periostin is upregulated by mechanical stress and promotes inflammation by upregulating IL-6 expression, which leads to LF degeneration and hypertrophy. Periostin may be a pivotal molecule for LF hypertrophy and a promising therapeutic target for lumbar spinal stenosis.

We report a 58-year-old male with a histopathologically proven grade 2 (G2) pancreatic neuroendocrine neoplasm and multiple abdominal node metastases by use of a laparoscopic pancreatic body and tail resection procedure, plus abdominal lymph node dissection. A primary pancreatic tail neuroendocrine tumor sized 20 × 25 mm was detected by contrast-enhanced computed tomography, somatostatin receptor scintigraphy (SRS), and fluorodeoxyglucose positron emission tomography (FDG-PET) examinations and pathologically diagnosed as a pancreatic neuroendocrine tumor (PNET, G2) based on positive immunostaining for somatostatin receptor (SSTR) type 2. Of three metastatic histopathological lymph nodes, two measured 18 × 21 and 10 × 12 mm, respectively, with whole strong SSTR immunostaining showing moderate uptake in SRS findings, whereas the other node, sized 8 × 10 mm, had strong SSTR immunostaining only in a small 6 × 6-mm-sized portion and showed no uptake in SRS findings, likely because of the limited spatial resolution of scintigraphy. On the other hand, only the largest node (18 × 21 mm) was visualized by FDG-PET. SRS may be useful for metastatic lymph node diagnosis based on SSTR immunostaining, though a disadvantage is the spatial resolution limitation.

Abstract
This study aimed to investigate the therapeutic effects of recombinant human thrombomodulin (rhTM) on acute lung injury (ALI) caused by sepsis in rats. Rats that underwent cecal ligation and puncture (CLP) were treated with or without rhTM, and then mortality was analyzed. In another set of experiments, ALI was assessed. Furthermore, microthrombosis in the lungs was investigated by immunohistochemistry. Moreover, plasma inflammatory and anti-inflammatory cytokines, such as TNF-α, high-mobility group box chromosomal protein 1 (HMGB-1), and IL-10, were evaluated by ELISA. Production of TNF-α and HMGB-1 by isolated tissue macrophages (Mφs) was assessed in vitro. Mortality after CLP was significantly improved by rhTM treatment. In addition, rhTM treatment improved the wet/dry weight ratio of the lungs, the pulmonary microvascular permeability, and the lung injury scores in animals that underwent CLP. Microthrombosis was detected in the lungs after CLP. These pathophysiological changes were blunted by rhTM treatment. Increased plasma TNF-α and HMGB-1 levels were blunted by rhTM treatment; however, the anti-inflammatory cytokine IL-10 was significantly greater in the rhTM(+) group than in the rhTM(-) group. Increased TNF-α and HMGB-1 production by the tissue Mφs stimulated with LPS were significantly blunted by rhTM treatment in vitro, but the production of IL-10 by the tissue Mφs was not changed in the cells incubated with rhTM. Overall, rhTM improved the mortality caused by septic peritonitis. The possible mechanisms are most likely anti-inflammatory and anticoagulant effects, which lead to the prevention of ALI.

Abstract
Background The present study aimed to examine the correlation between preoperative carcinoembryonic antigen levels in pancreatic juice (PJ‐CEA) and the histological subtype of intraductal papillary mucinous neoplasm (IPMN). Methods We enrolled IPMN patients who underwent endoscopic retrograde pancreatography between March 2002 and March 2018. Clinical factors associated with IPMN histological subtypes of 67 patients who underwent surgery were analyzed. Furthermore, the relationship between CEA immunohistochemistry findings and histological subtypes was investigated. Results Median PJ‐CEA were 15 ng/ml in the gastric type, 150 ng/ml in the intestinal type, and 175 ng/ml in the pancreatobiliary type. Both intestinal and pancreatobiliary types had significantly higher PJ‐CEA than the gastric type (p = 0.001). In the analysis of histological subtype predictors, high PJ‐CEA (≥63 ng/ml) only showed a significant difference in multivariate analyses (95% confidence interval 4.8–70.2; p < 0.001). Immunohistochemistry findings revealed significantly higher CEA expression in the non‐gastric type than in the gastric type (p < 0.001). The non‐gastric type showed a significantly worse prognosis than the gastric type (p = 0.017). Conclusion PJ‐CEA was an independent predictor of IPMN histological subtypes in a preoperative setting. High PJ‐CEA predict the non‐gastric type, while low PJ‐CEA predict the gastric type.

Abstract
We divided the patients with biliary tract cancer who underwent pancreaticoduodenectomy(PD)at our hospital into the 5-year recurrence-free and recurrence groups and investigated the prognostic factors. Additionally, we investigated the efficacy of adjuvant chemotherapy in patients with and without lymph node (LN) metastasis. There was no significant difference between the two groups for patient characteristics and perioperative factors. However, patients with LN metastasis tended to have a higher recurrence rate. For patients without LN metastasis, the median overall survival(OS)was not significantly different between the patients who received and did not receive adjuvant chemotherapy. For patients with LN metastasis, although it was not significantly different(p=0.234), the OS of patients who received adjuvant therapy was more than 3 times than that of patients who did not(58.6 months and 18.4 months, respectively). For patients with biliary tract cancer who underwent PD, positive LN metastasis may be a poor prognostic factor, and adjuvant therapy may possibly improve prognosis.

Abstract
The rapid aging of the population makes the detection and prevention of frailty increasingly important. Oral frailty has been proposed as a novel frailty phenotype and is defined as a decrease in oral function coexisting with a decline in cognitive and physical functions. Oral frailty has received particular attention in relation to Alzheimer's disease (AD). However, the pathomechanisms of oral frailty related to AD remain unknown. It is assumed that the mesencephalic trigeminal nucleus (Vmes), which controls mastication, is affected by AD pathology, and as a result, masticatory function may be impaired. To investigate this possibility, we included male 3 × Tg-AD mice and their non-transgenic counterpart (NonTg) of 3–4 months of age in the present study. Immunohistochemistry revealed amyloid-β deposition and excessive tau phosphorylation in the Vmes of 3 × Tg-AD mice. Furthermore, vesicular glutamate transporter 1-immunopositive axon varicosities, which are derived from Vmes neurons, were significantly reduced in the trigeminal motor nucleus of 3 × Tg-AD mice. To investigate whether the AD pathology observed in the Vmes affects masticatory function, we analyzed electromyography of the masseter muscle during feeding. The 3 × Tg-AD mice showed a significant delay in masticatory rhythm compared to NonTg mice. Furthermore, we developed a system to simultaneously record bite force and electromyography of masseter, and devised a new method to estimate bite force during food chewing in mice. Since the muscle activity of the masseter showed a high correlation with bite force, it could be accurately estimated from the muscle activity. The estimated bite force of 3 × Tg-AD mice eating sunflower seeds was predominantly smaller than that of NonTg mice. However, there was no difference in masseter weight or muscle fiber cross-sectional area between the two groups, suggesting that the decreased bite force and delayed mastication rhythm observed in 3 × Tg-AD mice were not due to abnormality of the masseter. In conclusion, the decreased masticatory function observed in 3 × Tg-AD mice was most likely caused by AD pathology in the Vmes. Thus, novel quantitative analyses of masticatory function using the mouse model of AD enabled a comprehensive understanding of oral frailty pathogenesis.

Abstract
Background Generally, a large tumor size of hepatocellular carcinoma (HCC) is associated with poor visibility and uncertainty in the surgical field which results in increased surgical difficulty as well as unfavorable postoperative outcomes. We performed intended preoperative trans-arterial embolization (TAE) in patients with a large HCC. In this study, we investigated the oncological significance of intended preoperative TAE for a large HCC, using a comparison between patients with and without TAE, and detailed analyses for pre- and post-TAE status. Methods A total of 411 patients who underwent hepatectomy for primary HCC at the University of Yamanashi Hospital between January 2007 and December 2018 were included in this study. The patients were divided into two groups: patients with larger HCCs (≥50 mm, n=51) and those with smaller HCC (<50 mm, n=360) according to the size of their HCCs. Comparison of clinicopathological features between these groups and clinical outcomes between the TAE and non-TAE groups were compared. In addition, a detailed analysis of each case in the TAE group was conducted, comparing clinicopathological factors between pre- and post-TAE status. Results The clinical unfavorable short- and long-term outcomes of patients with large HCCs (≥50 mm) were revealed compared to those with small HCCs (<50 mm). The prognostic analyses showed that a large tumor size and increased tumor markers, multiple tumor numbers, and others were adverse prognostic factors, and vascular invasions and residual tumors were included in the multivariate analysis. Further detailed analyses revealed that the average rates of change in tumor size and tumor shrinkage after TAE were − 48.6±35.6 mm and − 30.7±17.0%, respectively. Pathological high necrotic changes in the tumor, after multiple-times TAE aiming to a better effect, were related to a better prognosis in patients with large HCC. Poor prognostic factors became less common in patients who underwent intended preoperative TAE, and these patients had better prognoses. Conclusions The large tumor size of HCC is associated with unfavorable outcomes; the intended preoperative TAE for large HCC patients performed multiple times aiming to affect the tumor as much as possible might improve their prognoses.

Abstract
AIM To investigate the relationship between the intrahepatic expression of podoplanin (PDPN) and Kupffer cells (KCs) in ischemia-reperfusion (I/R) liver damage. METHODS C57Bl/6 mice were injected with 200 µl of clodronate liposomes (macrophage depletion; MDP group) to deplete KCs or control liposomes (control group) via the ophthalmic vein plexus 24 h prior to ischemia. Animals were subjected to 90 min of partial hepatic ischemia (70%), followed by reperfusion, and were then killed at designated time points. Serum and liver tissues were harvested for further analyses. RESULTS Serum ALT levels, mortality rates, and the percentage of necrotic area in liver sections were significantly higher in the MDP group than in the control group. PDPN was expressed in the lymphatic epithelium, interlobular bile duct epithelium, and in some hepatocytes in each group. Its expression in hepatocytes was down-regulated in the MDP group. The accumulation of platelets in the sinusoid was reduced 6 h after I/R in the MDP group. Tissue HGF and IGF-1 levels decreased in the MDP group. CONCLUSIONS These results suggest that KCs play a key role in the activation of platelets through direct contact with PDPN-positive hepatocytes in I/R livers.

Abstract
Diffuse‑type gastric cancer, also known as scirrhous gastric cancer, is characterized by a larger number of stromal cells, referred to as cancer‑associated fibroblasts (CAFs), than the number of cancer cells in the tissue. The present study focused on CAFs in gastric cancer and examined their potential as a blood biomarker. A total of 46 and 84 patients with gastric cancer were respectively included in a development and an independent validation cohort to assess the clinicopathological characteristics of plasma podoplanin (PDPN) levels. The prognostic impact of plasma PDPN was also investigated in the validation cohort. The cut‑off value of the plasma‑PDPN concentration was set to the median plasma PDPN concentration in the development cohort that was then divided into the high‑PDPN and low‑PDPN groups. The high‑PDPN group tended to have more diffuse‑type disease (P=0.079), which was further confirmed through logistic regression analysis (P=0.008). Kaplan‑Meier survival estimates indicated that the recurrence‑free survival rate was significantly lower in the high‑PDPN group (P=0.029). In conclusion, plasma soluble PDPN was demonstrated to be a marker for diffuse gastric cancer and may reflect the prognosis of this disease.

Abstract
We present 2 cases of carcinoma en cuirasse, an uncommon clinical manifestation of metastatic cutaneous breast cancer. Case 1, a 70-year-old woman, presented with diffuse erythematous, indurated skin lesions that covered her entire anterior chest wall. Skin biopsy revealed tumor cells in the dermis which were ER and PgR positive and HER2 negative. CT showed pleural and pericardial effusion which led to a final diagnosis of cutaneous metastasis from breast cancer. Fulvestrant monotherapy was initiated and maintained a good clinical effect for 40 months. She died of multiple liver metastasis after 53 months from her first visit. Case 2 was a 71-year-old woman, with a 24 month history of a left breast tumor that gradually accompanied erythematous skin indurations and erosion, which spread to her entire left chest wall and contralateral breast. Following skin biopsy and CT, she was diagnosed to have triple negative breast cancer with multiple lymph node and cutaneous metastasis. After 4 cycles of EC, capecitabine was administrated and her skin lesions improved rapidly, including the lymph nodes. She is currently alive after 12 months since her first visit and under chemotherapy against new cutaneous metastasis.

Abstract
As the elderly population increases, the number of patients with gastric cancer has also been increasing. Elderly people have various preoperative problems such as malnutrition, high frequency of comorbidities, decreased performance status, and dementia. Furthermore, when surgery is performed, high postoperative complication rates and death from other diseases are also concerns. The goal of surgery in the elderly is that short-term outcomes are comparable to those in nonelderly, and long-term outcomes reach life expectancy. Perioperative problems in the elderly include: (1) Poor perioperative nutritional status; (2) Postoperative pneumonia; and (3) Psychological problems (dementia and postoperative delirium). Malnutrition in the elderly has been reported to be associated with increased postoperative complications and dementia, pointing out the importance of nutritional management. In addition, multidisciplinary team efforts, including perioperative respiratory rehabilitation, preoperative oral care, and early postoperative mobilization programs, are effective in preventing postoperative pneumonia. Furthermore, there are many reports on the usefulness of laparoscopic surgery for the elderly, and we considered that minimally invasive surgery would be the optimal treatment after assessing preoperative risk.

Abstract
BACKGROUND The genetic changes underlying carcinogenesis in patients with risk factors of gallbladder carcinoma (GBC) remains controversial, especially in patients with pancreaticobiliary maljunction (PBM). This study aimed to clarify the association between risk factors of GBC and genetic changes using next-generation sequencing (NGS). METHODS We retrospectively analyzed resected tissues of 64 patients who were diagnosed with GBC (n = 26), PBM [with GBC (n = 8), without GBC (n = 20)], and chronic cholecystitis, used as a control group (n = 10). DNA was extracted from tumors and their surrounding tissues, which were precisely separated by laser-capture microdissection. Gene alterations of 50 cancer-related genes were detected by NGS and compared with clinical information, including PBM status. RESULTS The most frequent gene alterations in GBC tissues occurred in TP53 (50%), followed by EGFR (20.6%), RB1 (17.6%), and ERBB2 (17.6%). Gene alterations that were targetable by molecular targeted drugs were detected in 20 cases (58.8%). Statistical analysis of gene alterations and risk factors revealed that TP53 alteration rate was higher in GBC patients with PBM than those without PBM (p = 0.038), and the TP53 mutation rates in the epithelium of control patients, epithelium of PBM patients without GBC, peritumoral mucosa of GBC patients with PBM, and tumor tissue of GBC patients with PBM were 10, 10, 38, and 75%, respectively (p < 0.01). CONCLUSIONS TP53 alteration more than KRAS mutation was revealed to underlie carcinogenesis in patients with PBM.

Abstract
Recently, an expandable cage equipped with rectangular footplates has been used for anterior vertebral replacement in osteoporotic vertebral fracture (OVF). However, the postoperative changes in global alignment have not been elucidated. The purpose of this study was to evaluate local and global spinal alignment after anterior and posterior spinal fixation (APSF) using an expandable cage in elderly OVF patients. This retrospective multicenter review assessed 54 consecutive patients who underwent APSF for OVF. Clinical outcomes were compared between postoperative sagittal vertical axis (SVA) > 95 mm and ≤95 mm groups to investigate the impact of malalignment. SVA improved by only 18.7 mm (from 111.8 mm to 93.1 mm). VAS score of back pain at final follow-up was significantly higher in patients with SVA > 95 mm than SVA ≤ 95 mm (42.4 vs. 22.6, p = 0.007). Adjacent vertebral fracture after surgery was significantly more frequent in the SVA > 95 mm (37% vs. 11%, p = 0.038). Multiple logistic regression showed significantly increased OR for developing adjacent vertebral fracture (OR = 4.76, 95% CI 1.10–20.58). APSF using the newly developed cage improves local kyphotic angle but not SVA. The main cause for the spinal malalignment after surgery was postoperative development of adjacent vertebral fractures.

Abstract
OBJECTIVE The authors aimed to determine the efficacy of open-door laminoplasty with stand-alone autologous bone spacer for preserving enlarged lamina in patients with cervical myelopathy. METHODS Patients who underwent open-door laminoplasty for cervical myelopathy with stand-alone autologous bone spacer and underwent CT 1 week and 1 year after surgery were included in this study. There were 20 men and 13 women, with an average (range) age of 65.0 (37-86) years. Seventeen patients were younger than 70 years, and 16 patients were older than 70 years. Autogenous bone spacers made from spinous processes were used in all patients. Slits were made on both sides of the spacers. The lamina was raised with a curette, and a spacer was inserted without any sutures. Before surgery and 1 week and 1 year after surgery, the anteroposterior diameter (APD) of the spinal canal was measured using midsagittal-plane CT-multiplanar reconstruction. The bone union rate of the hinge side and autogenous bone spacer of each lamina was determined using CT images obtained 1 year after surgery. Results 1 year after surgery were evaluated using Japanese Orthopaedic Association (JOA) score. RESULTS The mean ± SD APD increase rate was 56.3% ± 21.3% 1 week after surgery and 51.7% ± 20.6% 1 year later. The average APD decrease rate was 2.9% ± 3.8%. The bone union rate on the hinge side was 100%, and that of autologous bone spacer was 93.8% 1 year after surgery. The mean APD decrease rate was 3.3% in patients younger than 70 years and 2.3% in those older than 70 years. There was no significant difference between the two groups (p > 0.05, nonpaired t-test). The JOA score averaged 10.1 before surgery and 13.3 a year after surgery (total score 17). The average improvement rate was 46.3% ± 26.4%. CONCLUSIONS The authors devised and implemented a technique for inserting an autologous bone spacer between the opened lamina and lateral mass without sutures. The enlarged spinal canal was maintained 1 year after surgery. This simple method does not require any instrumentation or additional cost to stabilize the opened lamina.

Abstract
OBJECTIVES The aim was to evaluate the relationship between cytoglobin (Cygb) expression and both clinicopathologic factors and prognosis in patients with pancreatic ductal adenocarcinoma (PDAC). METHODS Seventy-five patients with PDAC who underwent pancreatectomy between 2009 and 2014 at our department were included. Diagnosis was based on World Health Organization standards, with staging by TNM classification of Union for International Cancer Control. Expressions of Cygb, phosphoinositide-3 kinase, phosphorylated protein kinase B, interleukin-6, and vascular endothelial growth factor were evaluated by immunohistochemical staining of resected surgical specimens and densitometrical analysis. RESULTS Elevated expression of Cygb was found mainly in carcinoma cells of PDAC. Patients with low expression of Cygb showed significantly shorter disease-free survival and disease-specific survival than those with high expression. There was also a significant negative correlation between Cygb expression and the expressions of phosphoinositide 3-kinase, phosphorylated protein kinase B, interleukin-6, and vascular endothelial growth factor. In univariate analysis, Cygb expression, clinical stage, histologic tumor grade, lymphatic invasion, and vascular invasion were prognostic factors. In multivariate analysis, Cygb expression and the clinical stage were independent prognostic factors. CONCLUSIONS Loss of Cygb may contribute to tumor recurrence and poor prognosis of PDAC by increases in angiogenic factor.

Abstract
NADPH oxidases (NOXs) are a family of transmembrane proteins that generate reactive oxygen species. It was previously reported that patients with colon cancer who had high NOX5 expression had poor prognosis. However, no studies have investigated the cellular functions of NOX5 in colon cancer. The present study aimed to clarify the relationship between NOX5 and cancer development using an in vitro model. Reverse transcription‑quantitative PCR was performed to determine the NOX5 expression levels of colon cancer cell lines. NOX5‑knockdown experiments were conducted, and the effect on cell proliferation, migration, and invasion were analyzed. In addition, mRNA microarray was conducted to assess changes in gene profile. NOX5 mRNA expression was high in HCT116 cells and moderate in SW48 cells. NOX5 knockdown significantly inhibited cell migration and invasion in both HCT116 and SW48 cells; however, NOX5 knockdown reduced cell proliferation in only HCT116 cells. mRNA microarrays revealed a strong relationship between NOX5 expression levels and integrin‑linked kinase signaling pathways. The NOX5 expression in colon cancer cells affected cancer progression, especially cell motility. NOX5 may be a novel therapeutic target for the future development of treatments for colon cancer.

Abstract
BACKGROUND Pancreatectomy is a highly invasive procedure with extensive intraoperative blood loss (IBL) and high risk of postoperative pancreatic fistula (POPF). We conducted an experimental and retrospective clinical study to determine whether the malignant behaviors of pancreatic cancer cells were enhanced by exposure to blood components in vitro and to evaluate the oncological significance of high IBL and POPF in pancreatic cancer. METHODS This study included 107 patients undergoing radical pancreatectomy in the University of Yamanashi Hospital between 2011 and 2017, classified into high (n = 29) and low (n = 78) IBL groups. In vitro experiments included functional analyses of Panc-1 pancreatic cancer and normal mesothelial cells exposed to patient blood components, and clinical data were used to assess the contribution of IBL and POPF to patient outcomes. RESULTS The migration (p = 0.007), invasion (p < 0.001), and proliferation (p < 0.01) of Panc-1 cells were enhanced with platelet coculture. The ability of Panc-1 cells to adhere mesothelial cells was enhanced by plasma coincubation, especially in the presence of inflammation (p < 0.001). High IBL was associated with worse overall survival (p = 0.007) and increased locoregional recurrence (p = 0.003) in patients. POPF enhanced the negative prognostic significance of high IBL (p < 0.001 for overall survival, p = 0.001 for locoregional recurrence), indicating the oncological negative effects of high IBL and POPF. CONCLUSIONS Blood components, especially platelets, and inflammation enhance the malignant behaviors of pancreatic cancer cells, potentially contributing to poor prognosis for pancreatic cancer patients.

Abstract
OBJECTIVES Nutritional status significantly influences postoperative prognosis in gastrointestinal cancers. It has been evaluated using sarcopenia before treatments such as surgery and chemotherapy, despite constant changes in nutritional status. We consider that nutritional status at cancer recurrence is one of the important factors that affect treatment choice and intensity. This study evaluated the prognostic effects of improved postoperative nutritional status for people with colorectal cancer recurrence. METHODS We enrolled 209 participants with pathologically confirmed stage II or III colorectal cancer who underwent radical resection. Sarcopenia was diagnosed using the psoas muscle index obtained from analysis of three-dimensional computed tomographic images. We adopted the cutoff value that was proposed by Hamaguchi et al. (psoas muscle index < 6.36 cm2/m2 for men and < 3.92 cm2/m2 for women). Evaluation was performed before surgery and at the time of recurrence. Participants with preoperative sarcopenia who relapsed were divided into two groups at the time of recurrence: sarcopenia continuation and sarcopenia improvement. We compared the prognosis of the two groups and examined the effect of postoperative nutritional improvement. RESULTS Among the 209 participants, 81 (38.8%) had preoperative sarcopenia; this group had significantly lower overall survival than those without sarcopenia (P = 0.028). Colorectal cancer recurred in 48 participants. Of those 46, sarcopenia was evaluated at the time of recurrence; 19 of those 46 had preoperative sarcopenia. Preoperative sarcopenia did not affect the cancer recurrence ratio (sarcopenia, 23.5%; non-sarcopenia, 21.3%; P = 0.893). The sarcopenia-improvement group had higher overall survival than the sarcopenia-continuation group (P = 0.042). CONCLUSIONS Among participants with preoperative sarcopenia, the prognosis at the time of recurrence improved for the sarcopenia-improvement group compared to the sarcopenia-continuation group. In people with colorectal cancer and sarcopenia, nutritional management is important not only before but also after surgery.

Abstract
Background Traditionally, the surgery for simultaneous double cancer of the stomach and colon required a large incision to the upper and lower region of the abdomen. In this case, an artificial blood vessel was located under the skin after revascularization. Considering ischemia due to graft compression by incision retractor during laparotomy, this was difficult to do. This is a report on laparoscopic surgery for simultaneous double cancer of the stomach and colon after revascularization. Case presentation A 69-year-old man had early gastric cancer and advanced sigmoid colon cancer. He had suffered from thromboangitis obliterans and has undergone revascularization many times due to poor blood flow in his lower limbs. He had had some artificial blood vessels inserted under the skin, confirmed by blood vessel construction image by preoperative computed tomography (CT). There was a bypass vessel from the left axillary artery to the left femoral artery under the skin of the left thoracoabdominal. In addition, there were two bypass vessels from the left external iliac artery to the right femoral artery under the skin of the lower abdomen. One of the two bypasses was occluded. In the blood flow to the intestinal tract, the inferior mesenteric artery was already occluded. Peripheral blood flow in the common iliac artery depended on blood flow from the artificial blood vessel, and blood flow from the internal iliac artery to the rectum was poor. Laparoscopic Hartmann’s operation was performed for Stage II B (UICC 8th Edition) sigmoid colon cancer. Because the blood flow in the intestinal tract on the anal side was poor, we thought that anastomosis was at a high risk for leakage. Laparoscopic total gastrectomy was also performed simultaneously for two Stage I (UICC 8th edition) gastric cancers in the cardia and body. The location of the port site and stoma was carefully determined preoperatively to prevent damage and infection to the artificial blood vessels. Minimal invasive surgery was performed using laparoscopic surgery. Conclusions Laparoscopic surgery with small incisions is useful for patients with double cancer who need an approach to the upper and lower abdomen. Furthermore, laparoscopic surgery has less interference on graft in patients with artificial blood vessels under the skin by intraperitoneal approach.

Abstract
OBJECTIVES It has been reported that preoperative nutritional status in some gastrointestinal cancers has a significant effect on postoperative prognosis. However, there are few reports on esophageal cancer, especially for esophageal cancer patients who have undergone neoadjuvant therapy and surgery. Psoas muscle index (PMI) is widely known as an index for assessing preoperative nutritional status, and has recently been reported for its prognostic value in many malignancies. The aim of this study was to investigate and evaluate the clinical results in our hospital using the PMI method. METHODS We retrospectively investigated esophageal cancer in patients (clinical stage II or III) who underwent neoadjuvant therapy and surgical treatment (R0 cases) from January 2008 to December 2015. Applicable 63 cases were entered accordingly. In our hospital, nutritional supplements are used for nutritional management during preoperative adjuvant therapy, and these are administered to patients who have difficulty ingesting nutrition by feeding tube or total parenteral nutrition. The target value for nutritional supplement administration was 36 kcal/kg. Taking into account that chemotherapy for esophageal cancer was being performed using Harris-Benedict's basal energy expenditure (25 kcal/kg), we multiplied by 1.44 (active factor; 1.2, stress factor; 1.2) and set 36 kcal/kg as a guide. PMI was evaluated before neoadjuvant therapy and before surgery. We defined sarcopenia by PMI of the third lumbar vertebra (L3) by a computed tomography (CT) examination using 3-dimensional image analysis software, <6.36 for men and <3.92 for women, and investigated the effect of each on prognosis. RESULTS The prevalence of sarcopenia decreased from 74.6% (47 of 63) to 69.84% (44 of 63) during the pretherapeutic to preoperative period (P = 0.691), suggesting improved nutritional status. Regarding PMI divided by cutoff value for each sex (the cutoff value was the PMI mean value -2 SD [6.36 cm2 m2 for men and 3.92 cm2/m2 for women] of healthy individuals <50 y of age, which was reported as a standard for low skeletal muscle mass in Japanese individuals), there was an improvement observed in the preoperative compared to pretherapeutic period, but it was not obtained as a significant difference (pretherapeutic PMI; 0.87 ± 0.06 [mean ± SD], preoperative PMI; 0.89 ± 0.06 [mean ± SD], P = 0.18). In overall survival (OS) and disease-free survival (DFS), there was no significant difference in the short-term results with and without sarcopenia in the pretherapeutic group (both OS and DFS, P = 0.17). There was a significant difference with and without sarcopenia in the preoperative group in terms of OS and DFS (OS, P = 0.045; DFS, P = 0.043), which was short term due to nutritional intervention during preoperative adjuvant therapy. It was suggested that the results would be improved. CONCLUSIONS Improving nutritional status before surgery was shown to improve short-term prognosis in patients with esophageal cancer. It is hence suggested that it is important to maintain or improve nutritional status by intervention from the time of neoadjuvant therapy.

Abstract
BACKGROUND/AIM The high rate of recurrence and repetitive features of hepatocellular carcinoma (HCC) require specific treatment strategies. This study aimed to evaluate the long-term outcomes of recurrent HCC focusing on clinicopathological factors. PATIENTS AND METHODS A total of 104 patients who were treated with re-hepatectomy, radiofrequency ablation (RFA) or transcatheter arterial chemoembolization for recurrent HCC were analyzed. Post-recurrent prognoses were compared between each treatment group based on the presence of adverse prognostic factors (APFs) identified. RESULTS In the hepatectomy group, the prognosis of patients with APFs was significantly worse compared to those without APFs. By contrast, the survival rate of patients who underwent RFA was not significantly different from those with and without APFs. CONCLUSION Our results demonstrate the heterogeneity that exists in terms of the long-term survival of patients with recurrent HCC. The treatment strategy for recurrent HCC should be based on the assessment of presence of APFs to improve long-term prognosis.

Abstract
BACKGROUND/AIM This study examined the prognostic impact of the past history of breast cancer screening within the last 2 years (PH-BCS), for patients with triple negative breast cancer (TNBC), a subtype that carries extremely poor prognosis. PATIENTS AND METHODS Eighty-six consecutive cases with TNBC, who underwent surgery at our faculty from 2009 to 2015, were divided into two groups according to PH-BCS. Prognostic analyses for disease-free survival and overall survival between the two groups were performed. RESULTS The positive PH-BCS group (n=44) had a significantly better prognoses than the negative PH-BCS group (n=42) (p<0.001). No recurrent cases were observed in the positive PH-BCS group. In the negative PH-BCS group, tumor and node status and chemotherapy were indicated as significant prognostic factors, and further step-wise multivariate analysis revealed only node status as a significant prognostic factor. CONCLUSION Breast cancer screening at least every 2 years may improve the prognosis of TNBC.

Abstract
BACKGROUND/AIM Several studies have reported that DM is closely associated with an increased incidence of hepatocellular carcinoma (HCC). To clarify the effects of diabetes mellitus (DM) and antidiabetic medications on the prognosis of patients with non-B non-C (NBNC) HCC following curative initial hepatectomy. PATIENTS AND METHODS HCC patients (n=156) were divided into three groups according to the presence or absence of chronic viral hepatitis: hepatitis B virus (HBV) group, hepatitis C virus (HCV) group, and NBNC group. The clinical characteristics and survival outcomes were compared. In the NBNC group, univariate and multivariate analyses were conducted to determine prognostic factors. RESULTS The NBNC group had a higher incidence of DM, ethanol intake, and large nodules than the other groups. Disease-free survival (DFS) was significantly worse in the NBNC group than in the HBV group. In the NBNC group, insulin treatment was an independent prognostic factor for DFS and overall survival (OS). CONCLUSION Medications for DM that affect insulin resistance might be appropriate prognostic factors for NBNC-HCC.

Abstract
BACKGROUND/AIM Drains are frequently placed at the time of distal pancreatectomy (DP) to evacuate pancreatic juice and intra-abdominal exudate and obtain information on abdominal cavity status. However, the timing of drain removal remains debatable. Meanwhile, prolonged drain placement might increase the risk of postoperative pancreatic fistula (POPF), with a prevalence of 5-40%. Therefore, we examined the effect of removing the drain within postoperative day (POD) 3 on the risk of POPF development. PATIENTS AND METHODS A total of 108 consecutive patients who underwent DP between April 2015 and March 2020 were examined and divided into two groups according to the day of drain removal; hence, for some patients, the drain was removed on POD 1 (POD 1 group) and for others on POD 3 (POD 3 group). Furthermore, risk factors, including drain fluid amylase (DFA) levels, for developing POPF were investigated. RESULTS The overall rate of clinically relevant POPF was 4.6% and did not significantly differ between the POD 1 and POD 3 groups [4.5% and 4.9%, respectively (p=0.924)]. DFA levels on POD 1 did not significantly differ between patients with and without POPF. On POD 3 and POD 5, C-reactive protein (CRP) levels were significantly higher in patients with POPF than in those without (p=0.03 and p<0.001, respectively). CONCLUSION Early drain removal regardless of DFA level may reduce the risk of developing POPF. CRP measured on POD 3 and POD 5 appeared to be a useful predictor of clinically relevant POPF.

Abstract
BACKGROUND/AIM We aimed to evaluate the correlation between stroke volume variation (SVV) and intraoperative blood loss (IBL) in hepatocellular carcinoma (HCC) resection and examine the perioperative utility of SVV-based management. PATIENTS AND METHODS Ninety-five patients who underwent partial or sub-segmental hepatectomy for HCC between 2013 and 2019 at the University of Yamanashi Hospital were retrospectively analyzed. A correlation analysis between IBL and SVV was performed, and then all cases were divided into three groups: high, middle, and low-SVV groups. Perioperative short-term outcomes based on SVV groups were analyzed. RESULTS There was a weak but significant negative correlation between SVV and IBL (ρ=-0.372, p<0.001). Comparative analysis revealed that low-SVV was associated with a high incidence of postoperative complications and blood transfusion (p=0.018 and 0.037, respectively), and high-SVV was not related with postoperative complications. CONCLUSION SVV-based management is a significant and feasible strategy to achieve safe and exact surgical resection of HCC.

Abstract
UNLABELLED We investigated the effect of paravertebral muscle (PVM) on poor prognosis in osteoporotic vertebral fracture (OVF) and remaining lower back pain (LBP) in the thoracolumbar and lower lumbar regions. Additional OVF occurrence in the thoracolumbar and remaining LBP in the lumbar region was significantly related to PVM fat infiltration percentage. PURPOSE Paravertebral muscle (PVM) is an important component of the spinal column. However, its role in the healing process after osteoporotic vertebral fracture (OVF) is unclear. This study aimed to clarify the effect of PVM in thoracolumbar and lower lumbar regions on OVF clinical and radiological outcomes. METHODS This was a multicenter prospective cohort study from 2012 to 2015. Patients ≥ 65 years old who presented within 2 weeks after fracture onset were followed up for 6 months. PVM was measured at the upper edge of the L1 and L5 vertebral body in the magnetic resonance imaging (MRI) T2-axial position at registration. The cross-sectional area (CSA), relative CSA (rCSA), and fat infiltration percentage (FI%) were measured. Severe vertebral compression, delayed union, new OVF, and remaining low back pain (LBP) were analyzed. RESULTS Among 153 patients who were followed up for 6 months, 117 with measurable PVM were analyzed. Their average age was 79.1 ± 7.2 years, and 94 were women (80.3%). There were 48 cases of severe vertebral compression, 21 delayed unions, 11 new OVF, and 27 remaining LBP. Among all poor prognoses, only the FI% of the PVM was significantly associated with new OVF (p = 0.047) in the thoracolumbar region and remaining LBP (p = 0.042) in the lumbar region. CONCLUSION The occurrence of additional OVF in the thoracolumbar region and remaining LBP in the lumbar region was significantly related to the FI% of the PVM. Physicians should be aware that patients with such fatty degeneration shown in acute MRI may require stronger treatment.

Abstract
PURPOSE The purpose of this study was to clarify the predictors of efficacy of nab-paclitaxel plus gemcitabine(GnP)for patients with recurrence after resection for adenocarcinoma of the pancreas. METHOD Patients who had received GnP at our hospital were divided into 2 groups; effective group and non-effective group and we compared them. In addition, we compared the therapeutic effect of patients between well-differentiated adenocarcinoma and moderately differentiated adenocarcinoma. Furthermore, we compared the efficacy depending on the time of recurrence. RESULTS In patients with well-differentiated adenocarcinoma, the disease control rate was 93.6% and progression free survival was 8.6 months, whereas those in patients with moderately differentiated adenocarcinoma were 57.1% and 4.4 months, respectively. Patients who recurred at 7 months or later, had a better therapeutic response than the patients who recurred within 6 months after surgery. CONCLUSIONS GnP may be effective in patients with well-differentiated adenocarcinoma and in patients who recurred at 7 months or later.

Abstract
50's man who have performed anterior pelvic exenteration with lateral lymph node dissection for rectal cancer with pT4bN0M0, pStage Ⅱc about 2 years ago, was admitted to our hospital for the treatment of intrapelvic recurrence of rectal cancer. No distant metastasis was found in the computed tomography examination but the tumor invaded the dorsal side of the pubis. Because radical excision was impossible with these findings, he received chemoradiotherapy(CRT). Post-CRT imaging showed that the tumor of intrapelvic recurrence region reduced the size, and invasion of pubis had disappeared and been markedly reduced. Thus, radical excision seemed possible at this point, and we decided to attempt operation after total 6 weeks of S-1(120 mg/day)regimen and radiation(40 Gy/20 Fr). We performed Miles' operation. The final pathological examination demonstrated that no viable tumor cells remained in the resected rectum specimen, confirming that a pathological complete response(pCR)had been achieved.

Abstract
Background Postoperative pancreatic fistula (POPF) is one of the most serious complications after pancreaticoduodenectomy (PD). Various factors have been reported as POPF risks, but the most serious of these is soft pancreas. To reduce POPF occurrences, many changes to the PD process have been proposed. This study evaluates short-term results of anastomosis technique for PD. Methods In total, 123 patients with soft pancreases who had undergone PD at Yamanashi University between January 2012 and August 2020 were retrospectively analyzed. We divided these patients into two groups depending on the time PD was performed: a conventional group (n = 67) and a modified group (n = 56). Results The rate of clinically relevant POPF was significantly lower in the modified group than that in the conventional group (5.4% vs 22.4%, p value < 0.001), with there being only one case of POPF in the modified group. There were no cases of POPF-related hemorrhaging in the modified group. On the third day after the operation, the amylase levels in the drainage fluid for the modified group became less than half (1696 vs 650 U/L). Multivariate analysis showed that the modified method was the independent predictors to prevent clinical POPF (p value = 0.002). Conclusions Our novel anastomosis technique for pancreatojejunostomy reduced POPF in PD, especially in cases where the patient had a soft pancreas.

Abstract
In this study, we aimed to analyse human cancer cell–platelet interactions in functional cell analyses and explore the molecular mechanisms behind tumour progression. Various functional analyses of gastric cancer (GC) cells were performed after direct/indirect co-incubation with platelets derived from GC patients. Further detailed expression and signalling analyses were performed after co-culture with direct and indirect GC cells–platelet contact. Malignant behaviours of cancer cells, such as proliferation, migration, invasion and adhesion, were significantly enhanced after direct co-incubation with platelets. Microarray analyses demonstrated changes in multiple genes, including epithelial–mesenchymal transition (EMT)-related genes. Among them, matrix metalloproteinase 9 was notably upregulated, which was validated by quantitative reverse transcription–polymerase chain reaction and western blot. Further, this change was only observed after direct co-incubation with platelets. This study demonstrated that platelets from GC patients promote malignant behaviours of GC cells through EMT-related signalling, especially by direct contact with tumour cells.

Abstract
Mechanical small bowel obstruction (SBO) is a common postoperative complication, and most cases are caused by postoperative adhesions. We herein report a case of SBO with superior mesenteric vein occlusion caused by a metal staple after laparoscopic appendectomy. A 35-year-old Japanese woman presented to our department with severe upper abdominal pain and vomiting. She had undergone laparoscopic appendectomy using a linear stapler 7 years before. Abdominal CT showed mild small intestinal dilation with mesenteric edema and volvulus of the small bowel mesentery. Moreover, occlusion of the superior mesenteric vein was observed. Emergency exploratory laparoscopy revealed a strangulated SBO caused by a free unformed staple. The obstruction was released by a laparoscopic technique without bowel resection. The number of laparoscopic surgeries has recently been increasing, and complications specific to laparoscopic surgery have been recognized. All spilled and unformed staples should be removed to the greatest extent possible during laparoscopic operations.

Abstract
Background The aim of this study was to investigate the populations and functions of hepatic and splenic macrophages (Mfs) in non-alcoholic fatty liver disease (NAFLD). Materials and Methods Experiment 1: Wild-type and STAM® mice were given chow or high-fat diets for designated periods. In isolated Mfs, phagocytosis and cytokine production were assessed. Immunohistochemistry for CD68 and F4/80 and expression of CD14 and CD16 were assessed. Experiment 2: Bone marrow cells harvested from enhanced green fluorescent protein (EGFP) mice were transplanted into wild-type mice with or without splenectomy after total body irradiation that was kept on methionine- and choline-deficient diets. Results Experiment 1: The number of CD68-positive cells and the percentage of F4/80-positive/CD68-positive cells increased with the progression of NAFLD. Production of TNF-α and IL-6 by hepatic Mfs was greater than that by splenic Mfs in mice with NASH. The number of CD14+CD16− Mfs increased in the spleen and decreased in the liver in animals that had progressed to NASH. Furthermore, the number of CD14+CD16+ hepatic Mfs was increased in animals that had progressed to NASH with fibrosis. Experiment 2: EGFP-positive cells were observed in the liver after transplantation. In the splenectomy group, EGFP-positive Mfs were also observed; however, the number was significantly less than that in the sham operation group. Conclusion The populations and functions of hepatic and splenic Mfs are altered during the progression of NAFLD. In addition, increased hepatic Mfs during the progression of NAFLD may migrate from bone marrow to the liver via the spleen.

Abstract
Human alcoholic hepatitis (AH) carries a high mortality rate. AH is an acute-on-chronic form of liver injury characterized by hepatic steatosis, ballooned hepatocytes, neutrophil infiltration, and pericellular fibrosis. We aimed to study the pathogenesis of AH in an animal model which combines chronic hepatic fibrosis with intragastric alcohol administration. Adult male C57BL6/J mice were treated with CCl4 (0.2 ml/kg, 2×weekly by intraperitoneal injections for 6 weeks) to induce chronic liver fibrosis. Then, ethyl alcohol (up to 25 g/kg/day for 3 weeks) was administered continuously to mice via a gastric feeding tube, with or without one-half dose of CCl4. Liver and serum markers and liver transcriptome were evaluated to characterize acute-on-chronic-alcoholic liver disease in our model. CCl4 or alcohol treatment alone induced liver fibrosis or steatohepatitis, respectively, findings that were consistent with expected pathology. Combined treatment resulted in a marked exacerbation of liver injury, as evident by the development of inflammation, steatosis, and pericellular fibrosis, pathological features of human AH. E. coli and Candida were also detected in livers of mice cotreated with CCl4 and alcohol, indicating pathogen translocation from gut to liver, similar to human AH. Importantly, liver transcriptomic changes specific to combined treatment group demonstrated close concordance with pathways perturbed in patients with severe AH. Overall, mice treated with CCl4 and alcohol displayed key molecular and pathological characteristics of human AH-pericellular fibrosis, increased hepatic bacterial load, and dysregulation of the same molecular pathways. This model may be useful for developing therapeutics for AH.

Abstract
UNLABELLED This study revealed the change in the paravertebral muscles in patients with osteoporotic vertebral fracture. Increased pain is likely to be the driver for reduced activity, reduced activities of daily living, and consequent increase in fat infiltration of the paravertebral muscles, assumed to be secondary to reduced activity level or, conversely, partial immobilization. INTRODUCTION To reveal the time courses and impact of the paravertebral muscles (PVMs) on the healing process of osteoporotic vertebral fractures and risk factors for PVM decrease. METHODS Consecutive patients with symptomatic osteoporotic vertebral fractures were enrolled in 11 hospitals. At enrollment and 3- and 6-month follow-up, PVMs, including the multifidus and erector spinae, were examined using magnetic resonance imaging (MRI). The PVM cross-sectional area (CSA) and fat signal fraction (FSF) were measured at L3. Low back pain (LBP), activities of daily living (ADLs), and risk factors for PVM decrease at the 6-month follow-up were investigated. PVM decrease was defined as > 1 standard deviation decrease of the CSA or > 1 standard deviation increase of the FSF. RESULTS Among 153 patients who completed the 6-month follow-up, 117 (92 women, 79%) had MRI of L3 at enrollment and 3- and 6-month follow-up (mean age at enrollment, 78.5 years). The CSA did not change 6 months from onset (p for trend = 0.634), whereas the FSF significantly increased (p for trend = 0.033). PVM decrease was observed in 30 patients (26%). LBP was more severe, and delayed union was more frequent in patients with PVM decrease (p = 0.021 mixed-effect model and p = 0.029 chi-square test, respectively). The risk factors for PVM decrease were ADL decline at the 3-month follow-up (adjusted odds ratio = 5.35, p = 0.026). CONCLUSION PVM decrease was significantly related to LBP and delayed union after osteoporotic vertebral fracture onset. ADL decline at the 3-month follow-up was a risk factor for PVM decrease. Therefore, restoring ADLs within 3 months after onset is important.

Abstract
Background:The widespread use of biologic agents has greatly improved the prognosis of rheumatoid arthritis (RA). On the other hand, elderly patients with RA are relatively increasing. Although achieving low disease activity is a goal for those elderly patients as well as young patients, the efficacy of tumor necrosis factor inhibitors were reported to be equally or slightly less effective in elderly patients than in young patients. There is a lack of evidence for the efficacy of abatacept (ABT) in elderly patients.Objectives:In this study, we aimed to clarify the efficacy of ABT in elderly and young patients with RA compared to csDMARDs.Methods:This is a multicenter, open-label, prospective, observational study. All patients with RA enrolled this study are refractory to csDMARDs and have not received any biologics. Either ABT or csDMARDs was administered at the discretion of physicians to elderly (65 years and older) and young (20-64 years) patients (ABT-elderly, ABT-young, control (CTL)-elderly, and CTL-young groups). Comparison was made between 4 groups of patients. The primary study endpoint was a good response by EULAR response criteria at week 24 after administration. The research procedure has been approved by the ethics committee of Toho University School of Medicine (Approval number: A17112).Results:A total of 219 patients, 127 in the ABT group and 92 in the CTL group, were enrolled in this study. The majority of patients were women (82.7%) with a mean age (±SD) of 64.9±13.6 years (74.5±5.9 years in the elderly group and 52.4±10.1 years in the young group). The ABT group had higher disease activity, higher HAQ, and higher steroid use rates and dosage than the CTL group. These were also observed in the elderly group. In the young group, although the ABT group had higher disease activity and higher HAQ than the CTL group, no difference was observed in steroid use rates and dosage. The ABT group more frequently achieved a good response by EULAR response criteria compared to the CTL group at week 24 (58.8% and 27.2%, respectively, p<0.0001). The ABT group also showed higher efficacy than the CTL group in the elderly and young groups with a good response. Regarding the improvement in DAS28-ESR and DAS28-CRP, the ABT group was also superior to the CTL group. There was no difference on efficacy between elderly and young patients from the ABT groups.Based on propensity score matching for disease activity at baseline, 61 matched pairs of patients treated with ABT or csDMARDs were statistically extracted. Although there was no significant difference in the rate of patients with a good response by EULAR response criteria between the ABT and the CTL groups, the ABT group showed significantly better response than the CTL group in the elderly. Furthermore, the ABT group was superior to the CTL group in improvement in both DAS28-ESR and DAS28-CRP, and similar results were obtained in the elderly. However, there was no significant difference between the ABT group and the CTL group in the young. In addition, elderly patients had significant improvement in DAS28-ESR compared with young patients in the ABT group.Conclusion:Treatment with ABT showed higher efficacy compared with CTL, particularly in elderly patients with RA.References:[1]Harigai M, et al.

Abstract
Background:There is a paucity of information on the current phenotypes, ethnic and geographic differences of PAN. A global PAN study group has been working for clinical subphenotype and GWAS studies.Objectives:This study is aimed to look for target organ associations in PAN.Methods:PAN patients fulfilling the EMA vasculitis classification algorithm were recruited. In addition to baseline characteristics, treatment and outcome data, occurrence of any of the clinical manifestations related to PAN during disease course was recorded.Factor analysis was used to analyse target organ associations of 306 patients. Five factors were identified by factor analysis of variables sex, paediatric-onset, HBV, monogenic disease relationship, cutaneous features, musculoskeletal symptoms, constitutional symptoms and involved areas (abdominal, renal, neurologic, ENT, cardiac, pulmonary).Results:PAN cohort from 7 countries were used (Italy: n=59, Japan: n=39, Mexico: n=29, Slovenia: n=14, Sweden:11, TUR: n=106, UK: n=48). 306 (M/F: 171/135 and Caucasian 77.1%, Asian 13.4%, and Hispanic 9.5%) patients were included. 8 were HBV-related, and 22 of TUR patients had a monogenic form of disease (FMF n=15, DADA2 n=7). 21.8% of patients were cutaneous-only PAN patients. 48.4% of patients had radiologic, 64% had biopsy-proven PAN. Median age at disease onset was 40 (IQR 27.0-57.5) years. During a median 57 (16-120) months follow-up, 39 (13%) patients died.Factor analysis revealed 5 factors that explained 54.1% of the original information on the matrix as follows:Factor 1,represented the association between gastrointestinal and renal involvement, male gender and negatively associated with cutaneous features;Factor 2,the association between monogenic relationship with paediatric onset disease;Factor 3,any of musculoskeletal findings with positive constitutional symptoms;Factor 4any neurologic involvement was associated with ENT and pulmonary findings;Factor 5cardiac involvement in non-HBV patients (Table).The eigenvalues of the 5 factors were 2.034, 1.470, 1.427, 1.079 and 1.030, in decreasing order, i.e., the highest contribution to the overall variance in the matrix came from the togetherness of the 4 clinical and demographic characteristics that made up Factor 1.Conclusion:Target organ associations could support distinctive subphenotypes in PAN. Factor 1 seems the most severe form. Patients with FMF or DADA2 have distinct target organ associations. The jury is out to decide whether these patients should be classified as ‘vasculitis associated with probable etiology’ just as HBV-related-PAN. Factor 4 might define a different subphenotype (ANCA- medium vessel vasculitis?).Disclosure of Interests:Omer Karadag: None declared, Ertugrul Cagri Bolek: None declared, Shunsuke Furuta: None declared, Giacomo Emmi: None declared, ALOJZIJA HOCEVAR: None declared, Andrea Hinojosa-Azaola: None declared, Aladdin J Mohammad Speakers bureau: lecture fees from Roche and Elli Lilly Sweden, PI (GiACTA study), Serdal Ugurlu: None declared, Fatma Alibaz-Oner: None declared, Ayten Yazici: None declared, Luca Quartuccio: None declared, Enrica Bozzolo: None declared, Lorenzo Dagna Grant/research support from: Abbvie, BMS, Celgene, Janssen, MSD, Mundipharma Pharmaceuticals, Novartis, Pfizer, Roche, SG, SOBI, Consultant of: Abbvie, Amgen, Biogen, BMS, Celltrion, Novartis, Pfizer, Roche, SG, and SOBI, Giuseppe Alvise Ramirez: None declared, Luca Cantarini: None declared, Gina Gregorini: None declared, Jeannin Guido: None declared, Sara Monti: None declared, Eduardo Martin-Nares: None declared, Franco Schiavon: None declared, Roberto Padoan: None declared, Hajime Kono: None declared, Augusto Vaglio: None declared, Saadettin Kiliçkap: None declared, Ali İhsan Ertenli: None declared, Haner Direskeneli: None declared, Seza Özen Consultant of: Novartis, Pfizer, Speakers bureau: SOBI, Novartis, David Jayne Grant/research support from: ChemoCentryx, GSK, Roche/Genentech, Sanofi-Genzyme, Consultant of: Astra-Zeneca, ChemoCentryx, GSK, InflaRx, Takeda, Insmed, Chugai, Boehringer-Ingelheim

Abstract
Cholestatic liver injury leads to liver dysfunction. The available evidence suggests that platelets can either promote or reduce liver injury and fibrosis. This study focused on the functions of the C-type lectin-like receptor 2 (CLEC-2), a new special platelet receptor that binds with podoplanin-activating platelets. The role of CLEC-2 and podoplanin in cholestatic liver injury was investigated. Mice were injected intraperitoneally with weekly doses of anti-CLEC-2 antibody (2A2B10) to achieve effective CLEC-2 inhibition in their platelets. Next, left and middle hepatic bile duct ligation (BDL) procedures were performed, and mice were euthanized 1 week later (2A2B10-BDL group). In addition, mice were prepared for control groups, and relevant histological and laboratory variables were compared among these groups. The inhibition of CLEC-2 resulted in increasing hepatocellular necrosis, hepatic inflammation, and liver fibrosis. In addition, podoplanin was strongly expressed in hepatic sinusoidal endothelial cells in BDL-treated mice. Moreover, in 2A2B10-BDL mice, total plasma bile acid levels were significantly increased. In summary, podoplanin is expressed on hepatic sinusoidal endothelial cells upon BDL. Platelets bind with podoplanin via CLEC-2 and become activated. As a result, the total bile acid pool is decreased. Therefore, the CLEC-2-podoplanin interaction promotes liver protection and inhibits liver fibrosis after cholestatic liver injury.

Abstract
BACKGROUND/AIM Elevated neutrophil-lymphocyte ratio (NLR) has been reported to be a poor prognostic factor in patients with colorectal cancer (CRC). However, no studies have focused on the dynamic change of preoperative NLR (pre-NLR) in CRC patients. We investigated the prognostic value of the change in NLR (ΔNLR) in CRC patients before and after surgery. PATIENTS AND METHODS We retrospectively analyzed the data from 307 patients with stage II or III CRC. We compared the clinicopathological factors, OS, and DFS among the various NLR factors. RESULTS The 5-year OS rate of the high ΔNLR group was significantly lower than that of the low ΔNLR group (p<0.01). The 5-year DFS rates of the high ΔNLR groups were worse than those in the low ΔNLR groups. In the multivariate analysis, ΔNLR was an independent prognostic factor (p=0.011). CONCLUSION Decreasing post-NLR was related to better OS and DFS even in high pre-NLR patients with CRC.

Abstract
BACKGROUND Postoperative complications have been recognized to have an adverse prognostic impact in various types of cancer. However, in a recent study, it has been reported that postoperative complications of total gastrectomy with splenectomy have little impact on the long-term outcomes of patients with gastric cancer. In addition, the mechanisms underlying the effect of postoperative complications on outcomes remain to be elucidated. We hypothesized that immunosuppression by postoperative complications may affect long-term outcomes in patients with esophageal cancer. METHODS In this retrospective study, we assessed in 153 patients with esophageal cancer who underwent curative subtotal esophagectomy at our hospital and examined the correlation between postoperative complications, and multiple clinicopathological factors, and long-term outcomes with the patients stratified by total lymphocyte count (TLC). RESULTS The median preoperative TLC was 1432. A total of 115 patients (75.2%) had a TLC of ≥ 1000/μL (high TLC group), and the remaining 38 patients (24.8%) had a TLC of < 1000/μL (low TLC group). Postoperative complications occurred in 39 of 153 cases (25.5%). There was no significant correlation between postoperative complications and any of the clinicopathological factors in either group. In the high TLC group, patients with postoperative complications had significantly lower overall and disease-free survival rates compared with those without complications (p < 0.001 and p < 0.01, respectively). In the low TLC group, no survival difference between patients with and without postoperative complications was observed. CONCLUSIONS Postoperative complications may have a minimal impact on long-term outcomes in immunodeficient patients.

Abstract
BACKGROUND/AIM Basaloid squamous cell carcinoma of the oesophagus (BSCCE) has poorer prognosis than conventional oesophageal squamous cell carcinoma (ESCC). This study is the first report on highly expressed miRNAs in BSCCE and their target genes. MATERIALS AND METHODS BSCCE and ESCC patients who underwent esophagectomy were selected for this study. Total RNA was extracted from formalin-fixed paraffin-embedded blocks to examine expression of miRNAs and target genes. miRNA mimic or inhibitor transfected cells were used in validation experiments. miRNA and mRNA quantification were performed by quantitative reverse transcription polymerase chain reaction (qRT-PCR). RESULTS miRNA microarray analysis revealed four candidate miRNAs. Further investigations including cell line experiments demonstrated that miR-3687 was a candidate miRNA and progesterone receptor membrane component2 (PGRMC2) was its target gene. PGRMC2 was found to be related to cell proliferation and local progression. CONCLUSION miR-3687 may be a candidate miRNA conferring BSCCE aggressiveness, and PGRMC2 is one of its target genes.
