Objective:To analyze the reflux parameters of patients with gastroesophageal reflux disease (GERD) in upright position, supine position and at 2 h after meals, and to explore the cut-off value, sensitivity and specificity of the reflux parameters in different positions and at 2 h after meals in GERD diagnosis.Methods:From January 2016 to July 2020, 200 GERD patients (GERD group) and 61 non-GERD patients (control group) who visited Huazhong University of Science and Technology Union Shenzhen Hospital (Former Nanshan District People′s Hospital), were selected. All the patients of the two groups received gastroesophageal reflux disease questionnaire (GERDQ), upper gastrointestinal endoscopy, esophageal high resolution manometry and 24 h esophageal pH combined impedance monitoring. T test, non-parametric test and chi-square test were used to compare the related parameters in upright position, supine position and at 2 h after meals between two groups and within each group. Receiver oparative characteristic (ROC) curves of reflux parameters in upright position, supine position and 2 h after meals were drawn to determine the cut-off value, sensitivity and specificity in GERD diagnosis. Results:The proportion of patients with acid reflux in supine position of the control group was higher than that of the GERD group (41.0%, 25/61 vs. 8.50%, 17/200), and the difference was statistically significant ( χ2=36.53, P<0.01). In the control group, the acid reflux time in upright position, number of acid reflux, acid exposure time (AET), longest reflux time and number of weak acid reflux were more than those of in supine position in the same group (6.00 min(2.00 min, 13.50 min) vs. 0.00 min(0.00 min, 1.50 min), 16.00(8.00, 27.00) vs. 1.00(0.00, 3.00), 0.90%(0.33%, 1.88%) vs. 0.00%(0.00%, 0.30%), 2.00 min(1.00 min, 4.00 min) vs. 0.00 min(0.00 min, 1.00 min), 7.00(3.00, 11.00) vs. 1.00(0.00, 2.00), respectively) and the differences were statistically significant ( Z=5.43, 6.61, 5.06, 3.58 and 6.24, all P<0.01). In the GERD group, the acid reflux time, number of acid reflux, AET, longest reflux time and number of weak acid reflux in upright position were higher than those in supine position (51.00 min, (31.00 min, 86.75 min) vs. 8.00 min(1.00 min, 42.00 min), 60.00(48.00, 83.75) vs.6.00(2.00, 19.50), 7.30%(3.90%, 12.10%) vs. 1.50%(0.20%, 6.50%), 7.00 min(4.00, 12.00 min) vs. 4.00 min(1.00 min, 17.00 min), 1.00(0.00, 3.00) vs. 0.00(0.00, 2.00), 7.00(3.00, 12.00) vs. 0.00(0.00, 1.00), respectively) and the differences were statistically significant ( Z=7.92, 11.22, 6.90, 2.56, 5.11 and 11.76, all P<0.05). The acid reflux time, number of acid reflux, AET, longest reflux time and number of weak acid reflux at 2 h postprandial were 3.00 min(2.00 min, 9.00 min), 10.00(5.00, 18.00), 0.90%(0.40%, 1.98%), 1.00 min(0.00 min, 3.00 min), 4.00(1.50, 8.50)and 28.50 min(15.00 min, 54.75 min), 35.00(24.00, 52.00), 8.30%(4.32%, 15.83%), 6.00 min(3.00 min, 11.00 min), 4.00(2.00, 7.25), in the control and GERD groups, respectively, which were significantly higher than those in supine position in the same group ( Z=4.30, 6.33, 5.50, 3.40, 5.71 and 3.76, 9.21, 5.76, 1.97, 10.46, all P<0.05). Among 200 GERD patients, 125 patients had symptoms recorded during the 24 h esophageal pH combined impedance monitoring, the incidence of reflux symptoms in upright position was higher than that in supine position (89.6%, 112/125 vs. 65.6%, 82/125), and the difference was statistically significant ( χ2=20.71, P<0.01). The results of ROC curve analysis showed that the accuracy of acid reflux time in upright position in GERD prediction was the highest, with AUC value of 0.94 and cut-off value of 24.5 min, and the sensitivity and specificity in GERD diagnosis were 81.50% and 95.08%, respectively. The prediction accuracy of acid reflux times in upright position and AET in upright position for GERD was secondary, AUC value both were 0.93 and the cut-off value of the acid reflux number in upright position was 39.5, and the sensitivity and specificity in GERD diagnosis were 84.00% and 95.08%, respectively. The cut-off value of AET in upright position was 2.75%, the sensitivity and specificity in GERD diagnosis were 85.00% and 93.33%, respectively. The AUC value, cut-off value, sensitivity and specificity of AET at 2 h postprandial were 0.91, 4.60%, and 73.49% and 95.00%, respectively. Conclusions:Both GERD patients and non-GERD patients have more reflux in upright position, especially within 2 h after meals. The diagnostic values of acid reflux time in upright position, number of acid reflux, AET and AET 2 h after meals for GERD is high, and the AUC values are all >0.90, which can be used as a more comprehensive basis for the analysis and diagnosis of GERD.
RÉSUMÉ
Objective To summarize the clinical symptoms of patients with non-erosive reflux disease(NERD) and reflux esophagitis(RE),which is helpful to the differential diagnosis.Methods Outpatients who met the criteria of NERD or RE according to the Montreal definition in Gastroenterology Department Wuhan Union Hospital from 2010-2014 were enrolled in our study.Clinical data were comprehensively collected.Incidence of disease,severity,frequency of esophageal and extraesophageal symptoms,and the rates of overlapping with functional dyspepsia (FD) or irritable bowel syndrome (IBS) were all studied.Results Totally 446 subjects were recruited,including 225 patients with NERD and 221patients with RE.The occurrence rates of esophageal symptoms including heartburn [76.0％ (171/225) vs 52.0％ (115/221),P ＜ 0.01] and acid regurgitation [74.7％ (168/225) vs 54.3％ (120/221),P ＜0.05] in NERD group were significantly higher than those in RE patients,with more severe and frequent (P ＜ 0.05).Despite the rates of food regurgitation were similar,NERD patients behaved more severely and frequently (P ＜ 0.05).Extraesophageal symptoms including throat burning and foreign body sensation in NERD group [40.9％ (92/225) vs 27.6％ (61/221),42.2％ (95/225) vs 31.7％ (70/221),all P ＜0.05] were also higher than those in RE group,the degree of which was more severe too (P ＜ 0.05).RE patients claimed a higher proportion of chronic cough.The incidences of overlapping with IBS in two groups were similar.But there were more patients with FD in NERD group [72.0％ (162/225) vs 62.9％ (139/221),P ＜ 0.05] than in RE group.Conclusions The menifestations and degree of esophageal and extraesophageal symptoms in patients with NERD or RE are different,as well as comorbidities such as FD and IBS.These results suggest that NERD and RE are independent diseases.

Objective To investigate the relationships among distal contractile integral (DCI), ineffective esophageal motility (IEM)and gastroesophageal reflux through high resolution manometry (HRM)in patients with gastroesophageal reflux disease (GERD).Methods A total of 69 patients with GERD were enrolled.All patients received HRM and 24 hour pH and impedance monitoring examination. Pearson correlation analysis was performed to analyze the correlation between DCI,number of invalid swallowing and DeMeester score.All the patients were divided into three groups according to the number of invalid swallowing in 10 times of 5 mL liquid swallowing test.Patients with 5 to 10 invalid swallowing was in IEM group (n=21),one to four was in abnormal motility group (n=19),and zero was in normal motility group (n=29).The t test was performed for comparison of average DCI,average DCI of residual effective swallowing,DeMeester score,acid reflux time,bolus exposure time and proximal reflux times among the three groups.Results Among the 69 patients with GERD,there was negative correlation between DCI and DeMeester score (r=-0.363,P =0.003)in 10 times of 5 mL liquid swallowing test;the number of invalid swallowing was positively correlated with DeMeester score (r=0.374,P =0.002). The mean DCI in 10 times of 5 mL liquid swallowing of normal motility group,abnormal motility group and IEM group was (1 458.96±545 .10),(986.48 ±577.50)and (288.50 ±167.25 )mmHg·s·cm, respectively,and that of IEM group was lower than normal motility group and abnormal motility group (t =-11 .42 and -2.12,both P <0.05).The average DCI of residual effective swallowing of normal motility group,abnormal motility group and IEM group was (1 458.96 ± 545 .10 ),(1 187.90 ± 669.40)and (450.78 ±350.73 )mmHg ·s ·cm,respectively,and that of IEM group was also lower than normal motility group and abnormal motility group (t = -8.05 and -5 .27,both P <0.01 ).The DeMeester score of IEM group (15 .42±8.79)was higher than that of normal motility group (6.34±3.45),and the difference was statistically significant (t=2.43,P <0.05).The acid reflux time and bolus exposure time of IEM group were (54.93 ± 37.07 )min and (0.64 ±0.49 )%,respectively,which were longer than abnormal motility group ((37.37±22.66)min,(0.52 ±0.24)%)and normal motility group ((21 .22 ± 13.98)min,(0.39 ±0.14)%),and the differences were statistically significant (t =2.36,2.17,2.60 and 2.54,all P <0.05).The total number of reflux of IEM group and abnormal motility group were 67.10± 32.94 and 57.26±38.90,which were both more than that of normal motility group (44.61 ±23.84),and the differences were statistically significant (t =2.48 and 2.17,both P <0.05 ).Conclusions DCI and the number of invalid swallowing can predict reflux condition of GERD patients in a certain degree.The contraction strength of esophageal body was the weakest and esophageal clearance was the worst in IEM group.

Weight increasing would happen with the control of glucose in diabetic patients,whether the application of insulin or that of oral medication.Long-term and effective weight control should be done in order to lower the mortality rate.A large number of studies have shown that the mortality rate has increased along with weight gain,especially death caused by cardiovascular disease.The following measures can be used:(1)Rational target should be formulated.It would be the best that weight decrease 0.5~1.0 kg every week.(2)Diet should be controlled.Low-calorie,high protein,low-fat diet can be used.(3)Exercise therapy:Aerobic exercise will be recommended.(4)Drug intervention treatment:Metformin or Thiazolidinediones drugs can be use,Sibutramine or Orlistat can be used in the patients with serious obesity.
