Butyrate acts as a regulator in multiple inflammatory organ injuries. However, the role of butyrate in acute liver injury has not yet been fully explored. In the present study, we aimed to investigate the association between butyrate and lipopolysaccharide (LPS)-induced acute liver injury and the signaling pathways involved.

LPS-induced acute liver injury was induced by intraperitoneal injection of LPS (5 mg/kg) in G-protein-coupled receptor 43 (GPR43)-knockout (KO) and wild-type female C57BL/6 mice. Sodium butyrate (500mg/kg) was administered intraperitoneally 30 min prior to LPS exposure. Liver injury was detected by serum markers, tissue morphology, and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL). Pro-inflammatory-factor levels were detected by enzyme-linked immunosorbent assay and real-time polymerase chain reaction (RT-PCR). Cell models were first treated with sodium butyrate (4 μmol/mL), followed by LPS (1 μg/mL) half an hour later in GPR43 small interfering RNA (siand IкBα were observed.

Sodium butyrate significantly attenuated LPS-induced liver injury by reducing the inflammatory response partially via the GPR43/β-arrestin-2/NF-κB signaling pathway.

The benefits of laparoscopic gastrectomy (LG) in elderly gastric-cancer patients still remain unclear. The purpose of this study was to evaluate the feasibility and safety of LG in elderly gastric-cancer patients.

We retrospectively evaluated patients who underwent LG or open gastrectomy (OG) between June 2009 and July 2015 in a single high-volume center. We compared surgical, short-term, and long-term survival outcomes among an elderly (≥70 years old) LG (ELG) group (
=
114), a non-elderly (<70 years old) LG (NLG) group (
=
740), and an elderly OG (EOG) group (
=
383).

Except for extended time to first flatus, the surgical and short-term outcomes of the ELG group were similar to those of the NLG group. The ELG group revealed comparable disease-specific survival (DSS) rates to the NLG group (64.9% vs 66.2%,
=
0.476), although the overall survival (OS) rate was lower (57.0% vs 65.5%,
<
0.001) in the ELG group than in the NLG group. The ELG group showed longer operation time than the EOG group (236.4 ± 77.3 vs 179 ± 52.2 min,
<
0.001). The ELG group had less estimated blood loss (174.0 ± 88.4 vs 209.3 ± 133.8,
=
0.008) and shorter post-operative hospital stay (8.3 ± 2.5 vs 9.2 ± 4.5,
=
0.048) than the EOG group. The severity of complications was similar between the ELG and NLG groups. Multivariate analysis confirmed that LG was not a risk factor for post-operative complications.

LG is a feasible and safe procedure for elderly patients with acceptable short- and long-term survival outcomes.

Distal pancreatic carcinoma is one of the most lethal cancers largely due to its high incidence of distant metastasis. This study aims to assess the prognostic value of splenic-vasculature involvement in resected distal pancreatic carcinoma.

In this retrospective study, we collected the clinicopathologic information of 454 patients with pancreatic cancer and performed univariate and multivariate analyses to identify factors associated with progression-free survival (PFS) and overall survival (OS), with an emphasis on the prognostic value of splenic-artery and -vein involvement.

Univariate analysis revealed that larger tumor size, non-intraductal papillary mucinous neoplasm (non-IPMN)-associated adenocarcinoma, poor differentiation, stage pT3, nodal metastasis, lymphovascular invasion, perineural invasion, and pathologic and radiographic evidence of splenic-vein invasion were significantly associated with shorter PFS and OS (all
 < 0.05). Multivariate analysis confirmed non-IPMN-associated adenocarcinoma, stage pT3, stage pN1-2, and post-operative adjuvant chemotherapy as independent risk factors for both PFS and OS, and larger tumor size and radiographic evidence of splenic-artery invasion as predictors of PFS only.

Guidelines should be developed for a uniform approach with regard to the examination and reporting of the status of the splenic vasculature when dealing with distal-pancreatic-cancer specimens.

Lenvatinib is used for unresectable hepatocellular carcinoma (u-HCC) as first-line, as well as second- and third-line therapy in Japan. We evaluated the therapeutic efficacy of newly developed ramucirumab when given after lenvatinib for post-progression treatment.

Of 385 patients with u-HCC and treated with lenvatinib at 16 different institutions in Japan between May 2018 and January 2020, 28 who received ramucirumab as the next treatment were enrolled and therapeutic responses were evaluated in a retrospective manner.

The median age of the 28 patients given ramucirumab was 70 years and the median albumin-bilirubin score was -2.19. Of the 28 patients, 23 were male, 21 were classified as Child-Pugh A and 7 as Child-Pugh B, and 25 were Barcelona Clinic Liver Cancer Stage C. Ramucirumab was given as second-line therapy in 14, third-line in 9, and fourth-line in 5. Therapeutic response was obtained in only 26 patients; the objective response rate was 3.8% (1/26) and the disease-control rate was 42.3% (11/26), with a median period to progression of 2.0 months. The reasons for discontinuation of ramucirumab were progression of disease in 16 and Grade 3 adverse events (gastrointestinal bleeding, ascites) in 2.

The anticipated therapeutic efficacy of ramucirumab for post-progression treatment following lenvatinib was not seen in our early experience.

Endoscopic resection, including endoscopic submucosal dissection (ESD) and endoscopic full-thickness resection (EFR), was used to resect small gastric submucosal tumors (SMTs). Our team explored a method of tumor traction using a snare combined with endoclips to assist in the resection of SMTs. This study aims to explore the safety and effectiveness of the method.

This research performed a propensity-score-matching (PSM) analysis to compare ESD/EFR assisted by a snare combined with endoclips (ESD/EFR with snare traction) with conventional ESD/EFR for the resection of gastric SMTs. Comparisons were made between the two groups, including operative time,
resection rate, perioperative complications, and operation-related costs.

A total of 253 patients with gastric SMTs resected between January 2012 and March 2019 were included in this study. PSM yielded 51 matched pairs. No significant differences were identified between the two groups in perioperative complications or the costs of disposable endoscopic surgical accessories. However, the ESD/EFR-with-snare-traction group had a shorter median operative time (39vs 60min,
 = 0.005) and lower rate of
resection (88.2% vs 100%,
 = 0.027).

ESD/EFR with snare traction demonstrated a higher efficiency and
resection rate for gastric SMTs, with no increases in perioperative complications and the costs of endoscopic surgical accessories. Therefore, the method seems an appropriate choice for the resection of gastric SMTs.

EP is prone to being misdiagnosed as pancreatic cancer, causing unnecessary economic and physical harm to the patient. We report three cases of EP that were cured by steroids without relapse from 2017 to now. The clinical data of the three patients, including clinical manifestations, serological manifestations, imaging (ultrasound, computed tomography, and MRI), pathological diagnosis and treatment, and telephone follow-up of all patients, were retrospectively analysed. In addition, a literature search was conducted on the Web of Science and PubMed databases using key terms related to EP, considering case reports with no restrictions on the date of publication or language. In conclusion, we analysed 19 cases and determined the diagnostic criteria for EP. The diagnostic algorithm for EP can be used to diagnose EP easily. We hope that our standards and algorithm can reduce the rate of misdiagnosis and contribute to clinical diagnosis and treatment. In addition, we expect to evaluate more EP cases to test our diagnostic criteria and design a systematic diagnostic flow chart.
Abdominal pain is a debilitating symptom affecting ∼80% of pancreatic cancer (PC) patients. Pancreatic duct (PD) decompression has been reported to alleviate this pain, although this practice has not been widely adopted. We aimed to evaluate the role, efficacy, and safety of endoscopic PD decompression for palliation of PC post-prandial obstructive-type pain.

A systematic review until 7 October 2020 was performed. Two independent reviewers selected studies, extracted data, and assessed the methodological quality.

We identified 12 publications with a total of 192 patients with PC presenting with abdominal pain, in whom PD decompression was attempted, and was successful in 167 patients (mean age 62.5 years, 58.7% males). The use of plastic stents was reported in 159 patients (95.2%). Selleckchem ABR-238901 All included studies reported partial or complete improvement in pain levels after PD stenting, with an improvement rate of 93% (95% confidence interval, 79%-100%). The mean duration of pain improvement was 94 ± 16 days.

Esophageal and gastric cancers are most common in developing countries, while colorectal cancer forms the major GI malignancy in Western countries. However, a great shift in the predominant GI-cancer type is happening in countries under economically transitioning and, at the same time, esophageal and gastric cancers are reigniting in Western countries due to the higher exposure to certain risk factors. The development of all GI cancers is highly associated with lifestyle habits and all can be detected by identified precancerous diseases. Thus, they are all suitable for cancer screening. Here, we review the epidemiological status of GI cancers in China, the USA, and Europe; the major risk factors and their distribution in these regions; and the current screening strategies.
