Correlation analysis between different genotypes of CYP2C19, ERCC2 and XRCC1 and pathological indexes of gastroesophageal reflux and hiatal hernia in Xinjiang / 中国医师杂志

Objective The aim of this study was to investigate the correlation between different genotypes of CYP2C19,ERCC2 and XRCC1 and clinical indexes of gastroesophageal reflux and hiatal hernia in Xinjiang.Methods The clinical data of 101 patients with gastroesophageal reflux and hiatal hernia clinically diagnosed by people's hospital of Xinjiang Uygur Autonomous Region from January 2016 to December 2017 were prospectively studied,and Wilcoxon rank sum test was used to analyze the genotypes and relevant clinical indicators.Results There was statistically significant difference in the distance of hiatal hernia between patients with CYP2C19 containing A/A homozygous genotype and those with other two genotypes (A/G or G/G) (P ＜ 0.05),and there was statistically significant difference in intrabolus pressure (IBP) between patients with G/G homozygous genotype and those with A/G heterozygous genotype (P ＜0.05).Esophageal sphincter lower esophageal sphincter (LES) residual pressure,LES relaxation rate and percentage of invalid swallowing between patients with ERCC2 containing A/C heterozygous genotype and those with A/A homozygous genotype also has significant statistical difference (P ＜ 0.05).The more C contained in the genotype,the lower IBP maximum (on average),and this pattern has statistical significance (P ＜ 0.05);There was no statistical difference for all clinical indicators among different XRCC1 genotypes.Conclusions Different genotypes of CYP2C19 and ERCC2 are closely related to the clinical indexes of gastroesophageal reflux and hiatal hernia.CYP2C19 containing A/G or G/G genotype is correlated with gastroesophageal reflux disease (GERD) and the incidence of hiatal hernia.The population containing A/G and G/G genotypes of CYP2C19 may be with a high incidence of hiatal hernia.Homozygous G/G genotype may be a high risk factor for aggravating reflux esophagitis.A/C and C/C genotypes contained in ERCC2 genotype were correlated with the incidence of hiatal hernia.The more C bases contained in ERCC2 genotype,the greater the effect of reducing IBP,indicating that the more C bases contained in ERCC2 genotype may be negatively correlated with the prevalence of hiatal hernia.

CYP2C19 containing A/G or G/G genotype is correlated with gastroesophageal reflux disease (GERD) and the incidence of hiatal hernia. The population containing A/G and G/G genotypes of CYP2C19 may be with a high incidence of hiatal hernia. Homozygous G/G genotype may be a high risk factor for aggravating reflux esophagitis. A/C and C/C genotypes contained in ERCC2 genotype were correlated with the incidence of hiatal hernia. The more C bases contained in ERCC2 genotype, the greater the effect of reducing IBP, indicating that the more C bases contained in ERCC2 genotype may be negatively correlated with the prevalence of hiatal hernia.

Percutaneous mechanical devices for supporting the left ventricular failure / 中南大学学报(医学版)

This article reviews the indications,contraindications,functionality,and complications for various percutaneous devices that can be used to support the left ventricular failure.We also reviews the anesthetic effect for these devices.A literature review was performed using PubMed.When the heart experiences end-stage systolic ventricular failure,it is generally unable to restore its practical function with pharmacological therapy alone.Percutaneous ventricular support devices have been introduced and used successfully to support a failing ventricle in a variety of settings.These devices include intra-aortic balloon pump,TandemHeart,and Impeller,as well as veno-arterial extracorporeal membrane oxygenation for left ventricular support.These devices are typically accessed percutaneously through the femoral vessels and/or the jugular vein(s),although other sites are possible in unique cases.
