Abstract
AIMS: We conducted a dose-response meta-analysis to explore the association between alcohol and particular alcoholic beverages with risk of esophageal cancer (EC) by histological type [esophageal squamous cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC)] and whether the association differs according to gender. METHODS PubMed and Web of Science databases were searched for relevant articles published between January 1960 and December 2019. The pooled relative ratios (RRs) and 95% confidence interval (CI) were calculated with the fixed or random effect model. The dose-response relationship was assessed by restricted cubic spline. RESULTS A total of 74 published articles involving 31,105 cases among 3,369,024 participants were included in this meta-analysis. The pooled RRs of the highest versus lowest alcohol intake were 3.67 (95% CI, 2.89,4.67) for EC, 5.11 (95% CI, 3.60,7.25) for ESCC and 0.96 (95% CI, 0.79,1.16) for EAC. The above-mentioned associations were observed in cohort design, for different alcoholic beverages (beer, wine and liquor/spirits) and gender. Evidence of a nonlinear dose-response relationship for EC risk with alcohol intake was found (Pnon-linearity < 0.001), and a linear relationship (Pnon-linearity = 0.216) suggested that the risk of ESCC increased by 33% for every 12.5 g/day increment of alcohol intake. CONCLUSIONS This meta-analysis suggests that alcohol intake might significantly increase the incidence of EC, especially for ESCC.

Abstract
OBJECTIVE To evaluate the safety and effectiveness of magnesium sulphate for reducing the incidence of the emergence agitation in patients undergoing surgery for esophageal carcinoma with general anesthesia. METHODS This randomized, double-blind, controlled clinical trial was conducted in patients undergoing elective radical resection of esophageal carcinoma in Sichuan Provincial People's Hospital between October, 2015 and March, 2016. The patients underwent surgeries under general intravenous anesthesia, and after anesthesia induction, the patients were infused with magnesium sulphate at the rate of 0.1 mL·kg-1·h-1 (2.5 g magnesium sulphate in 50 ml saline pumped at 5 mg·kg-1·h-1) or saline (control group) at the same speed until the end of the surgery. The Riker's sedation agitation scale, pain score, muscle tension score, extubation time, residence time in the postanesthesia care unit (PACU), and adverse reactions were recorded. RESULTS A total of 108 patients were enrolled including 57 in magnesium sulphate group and 51 in the control group. Riker's sedation agitation scale in the PACU, pain score, and muscle tension score were all significantly lower but the extubation time was longer in magnesium sulphate group than in the control group (P<0.05). In all the patients, blood Ca2+ level was reduced significantly after the operation; blood Mg2+ level was significantly lowered postoperatively in the control group, and the postoperative Mg2+ level was significantly higher in magnesium sulphate group than in the control group (P<0.05). Mg2+ level underwent no significant variations in magnesium sulphate group after the operation (P>0.05). The residence time in the PACU, postoperative Riker's sedation agitation scale score, and blood K+ level were all similar between the two groups(P>0.05). CONCLUSION Infusion of magnesium sulphate at 5 mg·kg-1·h-1 can significantly reduce the incidence of emergence agitation in patients undergoing esophageal carcinoma under general anesthesia without causing such complications such as muscle recovery delay or electrolyte disorder.

Abstract
OBJECTIVES C20orf54, also known as a human riboflavin transporter 2 (RFT2), encodes an open reading frame protein RFT2 newly identified to play an important role in esophageal carcinogenesis by modulating riboflavin uptake. Missense cSNPs on exon 3,1172 C>A (T391M) and 1246A>G (I416V) have been suggested to modulate protein expression. The aim of present study was to explore the association of C20orf54 functional SNPs with susceptibility to esophageal squamous cell carcinoma (ESCC) in a northern Chinese population. METHODS 240 patients with ESCC and 198 healthy individuals without overt cancer were chosen as our experimental subjects. Information about family address, sex, age, BMI, smoking and drinking habits and family history of cancer were collected. Blood samples were taken from all subjects and tumor tissues were freshly sampled from resected specimens. After DNA was extracted and amplified, the C20orf54 SNPs were sequenced by ABI 3730XL in BGI China. Frequencies were then calculated and associated with the collected suspicous risk factors. RESULTS Drinking status, a family history of ESCC, blood type and BMI were found to have great influence on the risk of developing ESCC. Overall genotype frequencies of the RFT2 SNP 1172 C>A (rs3746803) and 1246A>G (rs3746802) in ESCC patients are significantly different from that in healthy controls (x2=13.10, P=0.001 and x2=7.97, P=0.019, respectively). For RFT2 rs3746803, C/T+T/T genotype did not show a relationship with the risk of ESCC (the age and gender adjusted OR=0.66, 95% CI=0.41-1.05) when using C/C genotype as the reference. For RFT2 rs3746802, the A/G +G/G genotype demonstrated a significantly decreased risk to the development of ESCC (the age and sex adjusted OR=0.53, 95% CI=0.34-0.84) with A/A as the reference. CONCLUSIONS The present study suggests that the C20orf54 functional SNPs might be associated with a risk of ESCC development.
