Objective To explore the nutritional increased risk related factors in esophageal cancer patients after chemoradio‐therapy .Methods Sixty‐eight esophageal cancer patients undergoing concurrent chemoradiotherapy were prospectively investiga‐ted .The patient‐generated subjective global assessment(PG‐SGA) was adopted to grade the nutritional risk .All of the patients re‐ceived early nutrition education and short‐term nutrition support for severe malnutrition ,nutritional status was assessed again at the end of radiotherapy .The patients were divided into the mild‐to‐moderate malnutrition group[PG‐SGA(B)group] and the severe malnutrition group [PG‐SGA(C)group] according to the PG‐SGA score on admission .The body mass ,albumin(Alb) ,hemoglobin (Hb) ,white blood cells ,platelets ,neutrophils ,lymphocytes ,monocytes and other objective nutrition indicators were collected before and after chemoradiation .Results There were 24 cases in the PG‐SGA(B) group and 44 cases in the PG‐SGA(C) group;the gen‐der ,age and ethnic had no statistical differences between the two groups(P>0 .05) .Hb(χ2 =2 .710 ,P=0 .009) and Alb(χ2 =3 .743 ,P=0 .000) before chemoradiotherapy had no statistical difference between the two groups(P>0 .05);Hb and Alb after che‐moradiotherapy in the PG‐SGA(B) group were higher than those in the PG‐SGA(C) group .The body mass index(BMI)before and after chemoradiotherapy had statistically significant difference between the two groups (P<0 .05) .The percentage of body mass decrease in the two groups had no statistical significance (P=0 .487) .The PG‐SGA scores after chemoradiotherapy were positively correlated with the change of Hb ,Alb ,BMI parameters and percentage of weight decrease before and after chemoradiotherapy(rs=0 .240 ,0 .249 ,0 .282 ,0 .447 ,P<0 .05) .Conclusion The poor understanding of malnutrition ,the change of Hb ,Alb ,BMI parame‐ters and percentage of body weight decrease before and after chemoradiotherapy are the nutritional increased risk factors in esopha‐geal cancer patients after chemoradiotherapy .

Background: Gastroesophageal reflux disease (GERD) is a commonly seen disease of digestive system, and its prevalence is increasing year by year. Xinjiang is located in the northwestern part of China and is a multi-ethnic region. The diets consumed are mainly meat, sweet food and strong tea, and the incidence of GERD is high in Xinjiang. Aims: To compare the efficacy of 4-week and 8-week courses of proton pump inhibitors (PPI) in the treatment of mild erosive esophagitis (EE) and to explore the factors influencing the efficacy of PPI. Methods: A total of 151 LA-A/B grade EE patients from November 2020 to February 2021 at General Hospital of Xinjiang Military Region were recruited, and grading of gastroesophageal reflux disease questionnaire (GerdQ), STOP-Bang questionnaire, Pittsburgh sleep quality index (PSQI), self-rating anxiety scale (SAS), self-rating depression scale (SDS) were performed. Patients received 40 mg qd esomeprazole for 8 weeks. The factors influencing the efficacy of PPI were analyzed. Results: No significant difference in symptom remission rate was found between 4-week and 8-week courses of PPI (74.1% vs. 81.3%, P=0.163). Multivariate analysis results showed that high risk of obstructive sleep apnea-hypopnea syndrome (OSAHS) and presence of hiatal hernia were the factors influencing the efficacy of 4-week course of PPI (P<0.05) and presence of hiatal hernia was the factor influencing the efficacy of 8-week course of PPI (P<0.05). Conclusions: Symptom remission rates are similar between 4-week and 8-week courses of PPI for mild EE. The presence of hiatal hernia and high risk of OSAHS can increase the difficulty and prolong the course of PPI in the treatment of EE.
