Background: The treatment of postoperative anastomotic stenosis after excision of rectal cancer is challenging. Endoscopic balloon dilation and radial incision are not effective in all patients. We present a new endoscopy-assisted magnetic compression technique (MCT) for the treatment of rectal anastomotic stenosis.

However, its use for the treatment of complex biliary obstruction after major abdominal trauma has not been reported. This case report describes the successful use of MCA for the treatment of biliary obstruction resulting from major abdominal trauma.

In cases where patients have undergone an enterostomy, the stenosis can be easily resolved through magnetic compression. However, common magnetic compression techniques cannot be performed on those without enterostomy.

Background: Endoscopic balloon dilation is a minimally invasive treatment for colorectal stenosis. Magnetic compression anastomosis can be applied against gastrointestinal anastomosis. When combined with endoscopy, it offers a unique approach to the recanalization of colorectal stenosis.

Resveratrol is a polyphonous natural compound that has cardioprotective, anticancer, and anti-inflammatory properties. Studies have proved that resveratrol (RES) inhibits cancer cell proliferation, migration, and invasion and promotes apoptosis. Elevated expression of ryanodine receptor type 2 (RYR2) may participate in the pathway responsible for calcium metabolism as well as anti-apoptosis and anti-autophagy events in malignant tumor cells.

PNI is associated with poor outcome, metastasis, and recurrence in pancreatic cancer patients. There are very few treatments for PNI in pancreatic cancer.

We presume that the abnormity of the VEGF/VEGFR2 and its pathway gene Id1, Wnt2 and HGF expression in aged LSECs may be an important mechanism to affect liver regeneration of the elderly. LSECs from two different groups (adult and old) were isolated in a rodent model, and observed by SEM and TEM.

Resveratrol, a natural polyphenolic compound, is considered as a potent anticancer agent. Nevertheless, the molecular mechanisms underlying the effects of resveratrol and NAF-1 and their mediation of drug resistance in pancreatic cancer remain unclear.

Development of organ transplantation is restricted by the discrepancy between the lack of donors and increasing number of patients. The outcome of pediatric donors transplanted into adult recipients especially with donation after circulatory death (DCD) pattern has not been well studied. The aim of this paper is to describe our experience of 3 successful DCD donor child-to-adult liver transplantations lately.

MiR-221/222 overexpression significantly promoted pancreatic cancer cell proliferation and invasion while inhibiting apoptosis.

Methods: Seventy-two clean, conventional Sprague-Dawley rats were randomly divided into 4 groups (SAP; sham operation [SO], SAP + PPC, and SO + PPC; n = 18 per group). The SAP model was induced by injecting 4% sodium taurocholate (1 mL/kg) into the biliopancreatic duct.
We investigated the mechanism and effects of sorafenib on hepatic stellate cell (HSC) viability and in the liver tumor microenvironment. The expression of α-smooth muscle actin (α-SMA) was measured immunocytochemically in the LX2 cells treated with differing concentrations of sorafenib. Changes in the platelet-derived growth factor (PDGF)-BB and tumor growth factor (TGF)-β1 concentrations were detected in the LX2 supernatant using an enzyme-linked immunosorbent assay (ELISA).

The aim of this study was to investigate the expression of CXCR4 and β-catenin in pancreatic cancer.
Patients And Methods: A total of 48 pancreatic cancer samples and 8 normal pancreatic tissues were selected to detect CXCR4 and β-catenin expression by an immunohistological technique.
Various epidemiological studies have demonstrated that vitamin D may play important roles in the pathogenesis and progression of cancer. Vitamin D is one of the most pivotal nutraceuticals whose active metabolite, calcitriol (1,25-dihydroxyvitamin D3), possesses anti-proliferative, pro-apoptotic, and pro-differentiating capabilities. Accumulating evidence indicates that the potential benefits of using vitamin D in cancer are not only anti-cancer cell proliferation which is linked with its anti-inflammatory effects, including the suppression of prostaglandin metabolism and inhibition of NF-κB signaling, but also suppressing tumor metastasis and angiogenesis.

SAP was experimentally induced in rats by injection of 4% sodium taurocholate in the retrograde pancreatic duct. Three study groups were evaluated: Group I (sham-operated animals), Group II (SAP animals), and Group III (SAP animals treated with RES at 20 mg/kg/body weight, 5 min after induction of SAP).

Resveratrol (RES) is a traditional Chinese herbal medicine having anti-inflammatory properties. We sought to explore the role of RES in intestinal injury during severe acute pancreatitis (SAP) in a rat model study. For this purpose, RES-treated and sham-operated (SO) SAP rat models were established, and SAP was induced in rats by injecting 4% sodium taurocholate into the biliary-pancreatic duct.

The management of severe acute pancreatitis (SAP) is a challenge because of its high morbidity, which is due to systemic inflammatory response syndrome and multiorgan dysfunction syndrome. Therefore, it is important to explore therapies to control the disease's progression.

The L-arginine/NO pathway has been confirmed to play an important role in tumor development. Recent findings indicate that NO derived from L-arginine could influence angiogenesis factors, vascular permeability, perivascular-cell recruitment and vessel remodeling and maturation.

Severe acute pancreatitis (SAP) develops in 15-20% of patients with acute pancreatitis. The management of SAP is a challenging task owing to the fact that it can lead to morbid conditions like multiple organ failure and systemic inflammatory response syndrome, if left untreated. Resveratrol, a drug used in Chinese traditional medicine has shown potential to treat many symptoms of SAP due to its multiple physiological actions.
