Clinical outcomes of endoscopic versus laparoscopic resection for senile patients with gastric gastrointestinal stromal tumours (2 to 4 cm) originating from the muscularis propria layer.

Introduction: Currently, there still are no selection criteria for endoscopic resection (ER) versus laparoscopic resection (LR) of gastric gastrointestinal stromal tumours (GIST) (2 to 4 cm) originating from the muscularis propria layer (MP-GISTs).

Aim: To investigate and compare the long-term prognosis of ER and LR for resecting gastric MP-GISTs, with at least 5 years of follow-up.

Material And Methods: Between January 2010 and December 2015, 134 patients with gastric MP-GISTs were consecutively enrolled in this study.

Esophageal Mucosal Autograft for Preventing Stricture After Widespread Endoscopic Submucosal Dissection of Superficial Esophageal Lesions.

Background: Although esophageal mucosal autograft prevents esophageal stricture after widespread endoscopic submucosal dissec- tion and has been reported as a new technique, it is relatively unproven in clinical practice. This prospective study was conducted to evaluate our experience using esophageal mucosal autograft to prevent strictures after widespread endoscopic submucosal dissection in patients with widespread superficial esophageal lesions.

Methods: Between October 2017 and June 2018, 15 patients with widespread superficial esophageal lesions were consecutively treated with widespread endoscopic submucosal dissection and then underwent esophageal mucosal autograft.

Endoscopic resection of large (≥ 4 cm) upper gastrointestinal subepithelial tumors originating from the muscularis propria layer: a single-center study of 101 cases (with video).

Background And Aims: Although endoscopic resection (ER) is already established as a minimally invasive technique for small (< 4.0 cm) upper gastrointestinal subepithelial tumors originating from the muscularis propria layer (MP-SETs), published data of ER for large (≥ 4.0 cm) upper gastrointestinal MP-SETs are extremely rare and limited to case reports.

Knockdown of SAR1B suppresses proliferation and induces apoptosis of RKO colorectal cancer cells.

Colorectal cancer (CRC) is the third most commonly diagnosed cancer worldwide. SAR1 gene homolog B (SAR1B) is a GTPase that has been reported to have a central role in the regulation of lipid homeostasis and is associated with numerous diseases. However, its role in cancer, particularly in CRC, remains unclear.

Higher Levels of Pre-operative Peripheral Lymphocyte Count Is a Favorable Prognostic Factor for Patients With Stage I and II Rectal Cancer.

The clinical significance of peripheral blood parameters has been considered to be a potential prognostic indicator for malignancies. In this study, 224 colorectal cancer (CRC; n = 103; n = 121) patients who underwent resection were enrolled, and the pre- and post-operative clinical laboratory data within 1 week, before and after surgery, were collected. The prognostic value of the counts of white blood cell (WBC), neutrophil, lymphocyte and platelet, the neutrophil to lymphocyte ratio (NLR), and systemic immune-inflammation index (SII) were analyzed.

HLA-DQB1*03 genotype and perioperative blood transfusion are not conducive to the prognosis of patients with gastric cancer.

Background: Gastric cancer (GC) is a disease associated with a higher incidence and mortality, and some host genetic polymorphisms have been reported as potential factors contributing to the development of GC. In view of this, the study was conducted to investigate the effects of HLA-DQB1 gene polymorphisms and perioperative blood transfusion on prognosis of patients with gastric cancer (GC).

Methods: A total of 142 patients with GC (case group) and 150 healthy controls (control group) were enrolled.

INHIBITORY EFFECT OF LYCOPENE AGAINST THE GROWTH OF HUMAN GASTRIC CANCER CELLS.

Background: The aim of this study was to investigate the anti-proliferative effect of Lycopene on HGC-27 cells.

Materials And Methods: HGC-27 cells were treated with varying concentration lycopene for 24, 48, 72 h. The cell growth inhibition was analyzed by MTT.

Extraction optimization of carbohydrate compound from Huangqi using orthogonal design.

The effect of extraction time, extraction temperature and time on the yield of Huangqi carbohydrate compound (HQCC) was investigated using single factor and orthogonal experiment design. The influence by the parameters on the extraction yields of carbohydrate compound decreased in the order of: C (extraction number)>A (extraction time)>B (extraction temperature) according to the R values. Based on this analysis, and considering the carbohydrate compound extraction efficiency, the cost of energy and the feasibility of experiment, the optimum conditions of extraction were therefore determined as follows: extraction time 120min, extraction temperature 80°C, and extraction number 4.

Evaluation of antioxidant and immunity-enhancing activities of Sargassum pallidum aqueous extract in gastric cancer rats.

The effect of Sargassum pallidum (brown seaweed) aqueous extract on the immunity function and antioxidant activities in was studied gastric cancer rats. Treatment with Sargassum pallidum aqueous extract at oral doses 400, 600 or 800 mg/kg body weight was found to provide a dose-dependent protection against N-methyl-N′-nitro-Nnitrosoguanidine (MNNG)-induced immunity damage and oxidative injury by enhancing serum interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-10 (IL-10) levels, decreasing interleukin-6 (IL-6), interleukin-1β (IL-1β), tumor necrosis factor-alpha (TNF-α) levels, preserving normal antioxidant enzymes activities, and by inhibiting lipid peroxidation in gastric mucosa. It can be concluded that Sargassum pallidum aqueous extract may enhance the immunity and antioxidant activities in gastric cancer rats.

Antioxidant and immunity activities of Fufang Kushen Injection Liquid.

We investigated the effects of Fufang Kushen Injection Liquid (FFKSIL) on gastric immunity and oxidant-antioxidant status during N-methyl-N′-nitro-N-nitroso-guanidine (MNNG)-induced gastric carcinogenesis. The extent of lipid peroxidation and the levels of reduced glutathione (GSH) and activities of the GSH-dependent enzymes superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) were used to monitor the peroxidative balance. Enhanced lipid peroxidation in the gastric cancer animals was accompanied by significant decreases in the activities of GSH, GPx, GST and GR.
