1. Comparison and Interpretation of the East⁃west Consensus and Guidelines for Gastroesophageal Reflux Disease
Chinese Journal of Gastroenterology 2022;27(10):596-600
Since 2020, the Chinese Society of Gastroenterology, the Japanese Society of Gastroenterology and the American College of Gastroenterology have updated consensus or guidelines for gastroesophageal reflux disease (GERD). This article reviewed and compared the above ⁃ mentioned files in terms of definition, symptoms, diagnosis, treatment, management of refractory GERD, and adverse effects of long⁃term proton pump inhibitor (PPI) treatment, so as to provide references for the standardized diagnosis and treatment of GERD.

Objective To explore the mechanism underlying the anti-hemorrhoid effects of Qingji Liangxue mixture(QLM).Methods Models of acute hemorrhoid in rats were established using a croton oil preparation(COP)and glacial acetic acid.A total of 80 SD female rats were randomly divided into two major groups:the COP group and the glacial acetic acid group,each consisting of 40 rats.In the COP group,rats were further randomly assigned to the following subgroups:control group 1(group CA),model group 1(group CB),low-dose QLM group 1-1(group CC),high-dose QLM group 1-2(group CD),and diosmin group 1(group CE),with eight rats in each subgroup.In the glacial acetic acid group,rats were randomly divided into the following subgroups:control group 2(group GA),model group 2(group GB),low-dose QLM group 2-1(group GC),high-dose QLM group 2-2(group GD),and diosmin group 2(group GE),with eight rats in each subgroup.Except for the control groups,all other subgroups were treated with COP or glacial acetic acid then treated with various drugs for 7 days.HE staining was used to observe anorectal histomorphology induced by COP and glacial acetic acid.ELIS As were used to measure serum levels of IL-6 and TNF-α induced by COP.Additionally,the area of perianal ulcers induced by glacial acetic acid was recorded.Twenty-four C57 mice were randomly divided into a control group(group A),low-dose QLM group(group B),high-dose QLM group(group C),and adrenal chromazone tablet group(group D).Results QLM significantly improved the pathological injury of animal models with similar hemorrhoids,reduced the score of pathological changes induced by COP(P<0.05),reduced the serum levels of IL-6 and TNF-α(P<0.05),reduced the area of perianal ulcers induced by glacial acetic acid(P<0.05),and shortened the time of coagulation and bleeding(P<0.05).Conclusions QLM has a good anti-hemorrhoid activity,which may be achieved by anti-inflammatory effects,hemostasis,and reducing tissue damage.

The gastrointestinal microbiome is the most important and complex microecosystem in the human microecosystem,which participates in a variety of physiological processes of the human body and is related to a variety of disease processes.In recent years,the relationship between gastrointestinal microbiome and gastrointestinal tumors has attracted the attention of scholars,and a series of studies have been carried out on the exploration of gastrointestinal microbiota as a new non-invasive biomarker.This article reviewed the relationship between gastrointestinal microbiome and the diagnosis,occurrence and treatment of gastrointestinal tumors through esophageal cancer,gastric cancer,colorectal cancer,gastrointestinal microbiome and tumor treatment,so as to provide new ideas for finding potential molecular targets for prevention,treatment and intervention of tumors.
