Acupuncture, including manual and electroacupuncture (MA and EA), at the P5-6 acupoints stimulates afferents in the median nerve (MN) to modulate sympathoexcitatory cardiovascular reflexes. Transient receptor potential vanilloid type-1 (TRPV1) is present in afferents distributed in the region of acupoints. However, contribution of TRPV1 to activation of sensory nerves by acupuncture, leading to modulation of pressor responses has not been studied. We hypothesized that TRPV1 participates in acupuncture's activation of sensory fibers and neurons to modulate pressor reflexes...

Besides its well-known action to stimulate thyroid hormone release, Thyrotropin mRNA is expressed within the brain and Thyrotropin and its receptor have been shown to be present in brain areas that control feeding and gastrointestinal function. Here, the hypothesis that Thyrotropin acts on receptors in the dorsal hindbrain to alter food intake and/or gastric function was tested. Fourth ventricular injections of Thyrotropin (0.06, 0.6 and 6.0 µg) were given to rats with chronic intracerebroventricular cannulas aimed at the fourth ventricle...

BACKGROUND: Weight regain following bariatric surgery is not uncommon. Safe, effective weight loss treatment up to 1 year has been reported with the closed-loop gastric electrical stimulation (CLGES) system. Continuous recording of eating and activity behavior by onboard sensors is one of the novel features of this closed-loop electrical stimulation therapy, and may provide improved long-term weight maintenance by enhancing aftercare. METHODS: Four centers participating in a 12-month prospective multicenter randomized study monitored all implanted participants (n = 47) up to 24 months after laparoscopic implantation of a CLGES system...

BACKGROUND: Staging laparoscopy(SL) is a recommended technique for the staging of Gastric Cancer(GC) and provides the indication for a radical surgery. Considering the medical practice in China, the standardized and regular usage of SL is yet to be spread. However, existing guidelines vary and make an ambiguity of indication for SL. Besides, the specific indication for Chinese patients remains a niche. This study aims to the essential, missing information of Chinese patients and tries to normalize the indication of LS in medical practice in China...

Mason performed the first gastric bypass (GBP) for obesity in 1967 after having observed substantial weight loss in patients operated for gastric ulcer.  The weight loss after GBP is 30 % and 2/3 of patients with type II diabetes can stop their medication. Half of the patients can stop medication for hypertension or hyperlipidemia, 75% are cured from reflux and obstructive sleep apnea. GBP prolongs survival especially among diabetics. Restriction and malabsorption is of minor importance for weight loss. The mechanisms underlying weight loss and diabetes remissions are endocrine...

Infection with Helicobacter pylori (H. pylori) and the resulting gastric inflammation is regarded as the strongest risk factor for gastric carcinogenesis and progression. NF-κB plays an important role in linking H. pylori-mediated inflammation to cancer. However, the underlying mechanisms are poorly understood. In this study, we find that H. pylori infection induces miR-223-3p expression in H. pylori CagA-dependent manner. NF-κB stimulates miR-223-3p expression via directly binding to the promoter of miR-223-3p and is required for H...

Recent years, widespread long non-coding RNAs (lncRNAs) were identified and known as regulator of gene expression. Diabetic gastroparesis (DGP) is one of the most common chronic complications of diabetes mellitus. There was no research reported the role of lncRNAs in DGP. In this study, we firstly established a rat model of DGP by STZ injection. Then, we detected the expression of MALAT1 and found that expression of MALAT1 was up-regulated in rat model of DGP, comparing to the control group (P < .01)...

BACKGROUND/AIMS: The status of interferon (IFN) signaling pathway has been shown to be closely associated with the response of immune checkpoint blockade therapy against advanced human cancers. IFN-induced protein with tetratricopeptide repeats 2 (IFIT2), also known as IFN-stimulated gene 54 (ISG54), is one of the most highly responsive ISGs, which can inhibit the proliferation and migration of cancer cells, and regulate viral replication, resulting in anti-cancer and anti-viral effects...

BACKGROUND: During capsule endoscopy (CE) studies, the complete examination rate (CER) can be increased by prolonging capsule battery life or reducing gastric transit time (GTT) and/or small bowel transit time (SBTT). However, despite enhanced battery life, 10% of studies remain incomplete. Previously studied interventions to reduce SBTT and enhance CER have produced conflicting results. We hypothesize that this may be a consequence of an insufficiently potent stimulus of small bowel motility...

Gastric cancer continues to be a major cause of morbidity and mortality worldwide. Recently, there has been a growing interest in the host inflammatory response and there is increasing evidence that the neutrophil to lymphocyte ratio (NLR), which is a useful marker of systemic inflammation, can be an effective prognostic indicator in various types of malignant diseases. A total of 110 patients with stage IV gastric cancer who received chemotherapy of S-1 plus cisplatin were enrolled in this study. Eleven patients did not complete four cycles of the chemotherapy...

INTRODUCTION: Glucagon-like peptide-1 (GLP-1) receptor analogs are a group of therapeutic agents which mimic endogenous GLP-1, exerting their effect by the stimulation of the GLP-1 receptor with a wide distribution. Its activation increases insulin releasing dependent on blood glucose levels, suppression of glucagon secretion and a reduction of hepatic glucose output. It delays gastric emptying and increases satiety. Exenatide is the synthetic version of exendin-4, a natural peptide with similar properties to human GLP-1...

Programmed death-ligand 1 (PD-L1) acts as an immune checkpoint inhibitor in various cancers. PD-L1 is known to be more frequently expressed in EBV (+) gastric cancer (GC). However, the mechanisms underlying the regulation of PD-L1 expression in EBV (+) GC remain unclear. We investigated the basal and inducible PD-L1 expressions in GC cells. PD-L1 expression was upregulated upon treatment with IFNγ in both EBV (-) and EBV (+) GC cells. Upon stimulation with the same concentration of IFNγ for 24 h, EBV (+) SNU-719 cells showed dramatically higher PD-L1 expression levels by activating JAK2/STAT1/IRF-1 signaling than those of EBV (-) AGS cells...

BACKGROUND: The trigeminocardiac reflex (TCR) is defined as sudden onset of parasympathetic dysrhythmias including hemodynamic irregularities, apnea, and gastric hypermotility during stimulation of sensory branches of the trigeminal nerve. Since the first description of the TCR 1999, there is an ongoing discussion about a more flexible than the existing clinical definition. Aim of this work was to create a clinical surrogate definition through a systematic review of the literature. METHODS: In this meta-analysis study, literature about TCR occurrences was, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement, systematically identified through various search engines including PubMed (Medline), Embase (Ovid SP), and ISI Web of Sciences databases from January 2005 to August 2015...

BACKGROUND: Helicobacter pylori has undergone considerable adaptation to allow chronic persistence within the gastric environment. While H. pylori-associated diseases are driven by an excessive inflammation, severe gastritis is detrimental to colonization by this pathogen. Hence, H. pylori has developed strategies to minimize the severity of gastritis it triggers in its host. Superoxide dismutase (SOD) is well known for its role in protecting against oxidative attack; less recognized is its ability to inhibit immunity, shown for SOD from mammalian sources and those of some bacterial species...
