Objective: To observe the effects of Lulutong injection on microcirculation disturbance after burns. Methods: Eighty-eight patients with mild burn were randomly divided into two groups. From the first day after burn, the treatment group received 500 mg Lulutong injection intravenously injected in 5% glucose, once a day for 14 days as a therapeutic course. The control group was treated with 5% glucose. No large amount of solution was infused because the burned patients were mild and no shock was found. Both groups were received anti-infection treatment using 0.6 g of clindamycin. The morphology of nail-fold microcirculation , the state around the nail-fold microcirculation, hemorrheological parameters, changes in coagulation function 3, 7 and 14 days after burn and the side effects of drugs were observed. Results: Compared to the control group, in the treatment group, the arterioles dilated more markedly, the blood flow of micro-vessels became faster, the flowing score of nail-fold microcirculation decreased obviously, the state around the nail-fold microcirculation changed significantly, the total score declined faster, but no obvious changes were found in erythrocyte aggregation index, the number of leukocyte adhesion and coagulation function . There were 2 cases with dizziness. Conclusion: Lulutong injection may improve the microcirculation in patients with burn, and has little side effect.

Objective To evaluate the effect of csomeprazole with different dosage and usage regimes on intragastric pH of healthy volunteers. Methods It was a randomized, open-label, three-way crossover study. Fifteen healthy volunteers received esomeprazole with 3 different dosages (20 mg or 40 mg once daily or 20 mg twice daily) with 5 days each. Twenty-four continuous ambulatory intragastric pH was recorded at day 5 of each regime. Results The mean time of intragastric pH above 4 was higher in regime of 20 mg twice daily [(21.16 ±2.45) hours ] than that in regimes of 20 mg once daily [(18. 70±4.19) hours] and 40 mg once daily [(19.27±2.68 ) hours] (P<0.05). The percentages of the sleeping and active period that pH remained above 3,4,5 were significantly higher in regime of 20 mg twice daily(day time:95.0%±7.5% ,92.0%±10.6% ,86.7% ± 14.5% ;night time:93.2%± 13.1% ,87.8%±20.3% ,78.6%±28. 9 % )compared with regimes of 40 mg once daily(day time:87.9%±9.5% ,83.5%±11.7%,75.6%±15.50%, night time:75. 7%±20. 8%,66. 9%±23. 8%,53. 3%±30. 3%) and 20 mg once daily(day time: 85.1 % ± 16.3 %, 81.1 %± 18. 1%, 71.5 % ± 20.3 % ; night time: 72.9 % ± 30.5 %,67.2 % ± 31.9 %, 55.7 % ± 31.8 % ) (P< 0.05 ). Esomeprazole maintained intragastric pH above these pH thresholds for a similar propotion of sleeping and active periods with 40 mg once daily and 20 mg once daily.Conclusions Esomeprazole has strong inhibitory effect on intragastric acid. The regime of 20 mg twice daily is superior to 40 mg once daily and 20 mg once daily in both day and night time acid inhibition.There is no difference between esomeprazole 40 mg once daily and 20 mg once daily.

Objective To investigate the role of combined multichannel intralumminal impedanee-pH (MII-pH) monitoring in the diagnosis of gastroesophageal reflux disease (GERD). Methods Forty-four consecutive patients, who had heartburn symptom and without esophageal mucosal lesion, underwent combined MII-pH monitoring. Then rabeprazole test was performed for 14 days with 10 mg twice daily. Rabeprazole test was defined as positive if patients were totally heartburn symptom free in the second week. The normal values from 70 healthy volunteers who underwent MII-pH monitoring were served as controls. Results Conventional esophageal pH monitoring showed that 20 patients (45.5%) had pathologic esophageal acid exposure or positive acid reflux associated symptom index. MII-pH monitoring revealed that 2 patients were positive for weakly acidic reflux related to symptom index, thus increased the diagnostic yield to 50% (22/44). Furthermore, rabeprazole test demonstrated that 4 patients were positive which increased the diagnostic yield to 54.5%(24/44). Conclusion The detective rate of GERD will be elevated if combined with MII-pH monitoring in diagnosis.

Objective To investigate the prevalence of non-acidic reflux in patients with gastroesophageal reflux disease and its correlation extent with heartburn symptom by 24-hour combined multichannel intraluminal impedance-pH (MII-pH) monitoring. Methods Consecutive patients with chief complain of heartburn in gastrointestinal specialty clinic were enrolled. Patients were divided into erosive esophagitis (EE) group, non-erosive reflux disease (NERD) group after upper gastrointestinal endoscope, further diagnosed with 24-hour combined MII-pH monitoring and rabeprazole test. The MII-pH parameters were compared in these two groups. Results 36 cases of EE and 62 of NERD were enrolled. There was significant difference in acidic reflux frequency and acidic reflux time percentage between these two groups (P=0. 001 and 0. 002). The frequency of non-acidic reflux in EE and NERD groups was 37.3% (663/1777) and 44.3% (1220/2754) respectively (x2 =21. 723,P = 0. 000). The percentage of heartburn symptom positive index in patients with acidic reflux, non-acidic reflux , and total reflux in EE group was 36.1 % (13/36), 19.4 % (7/36) and 55.6%(20/36) respectively, while in NERD group was 27. 4% (17/62), 6.4 % (4/62) and 33.8% (21/62).Conclusion The percentage of non-acidic reflux in EE and NERD groups was 37.3% and 44.3%respectively, and the non-acidic reflux was highly related to heartburn symptom.

Objective To evaluate the clinical and manometric characteristics of achalasia.Meth-ods Patients diagnosed as having achalasia from July 2010 to July 2014 at our hospital were enrolled.High resolution manometry(HRM)results were analyzed.Data of Eckardt scale,MDADI and SF-36 were ana-lyzed.Results All subjects had dysphagia,35.6% (37 /104)accompanied with regurgitation,26.9%(28 /104)with heartburn and 17.3%(18 /104)with weight loss.According to HRM results and Chicago classification criteria,16.35%(17 /104)of the subjects were classified as type Ⅰ,76.92%(80 /104)as type Ⅱ and 6.73%(7 /104)as type Ⅲ.27.9%(29 /104),19.2%(20 /104)and 24.0%(25 /104)of the subjects finished Eckardt scale,MDADI and SF-36,respectively.Eckardt score was positively correlated with integrated relaxation pressure(IRP)(r =0.421,P <0.05)and MDADI physical score was negatively with IRP(r =-0.530,P <0.05).Conclusion Dysphagia often occurs as the chief complaint among acha-lasia patients.And type Ⅱ is the most common.IRP is an indicator of the severity of clinical symptoms and impairment of quality of life.

Objective To investigate the changes of esophageal intraluminal baseline impedance in patients with refluxesophagitis.Methods From December 2013 to August 2014,47 patients with reflux esophagitis and 17 healthy controls were enrolled.The patients with reflux esophagitis were graded according to Los Angeles classification (LA) grading standards.All subjects accepted 24 h multichannel intraluminal impedance (MII) pH examination,and the baseline value of impedance were measured.Independent sample t test was used to compare the difference in impedance between the two groups.Spearman rank correlation coefficient was performed to analyze the correlation between acid exposure time (AET) and the baseline impedance of patients with reflux esophagitis.Kruskal-Wallis test was used to compare the differences in baseline impedance of patients with different grades of reflux esophagitis.Results The impedance baseline value of reflux esophagitis group was (1 676.72±644.41) Ω,which was lower than that of healthy control group ((2 151.27± 322.05) Ω),and the difference was statistically significant (t =-3.883,P＜0.01).The AET of esophagus was negatively correlated with the baseline impedance of the patients with reflux esophagitis (r=-0.530,P＜0.01).The baseline impedance of patients with grade LA-A and grade LA-B reflux esophagitis were 1 823.62 Ω (1 515.38 52 Ω,2 208.38 Ω) and 1 771.81 Ω(1 304.75 52 Ω,2 080.50 Ω),respectively,and the difference was not statistically significant (Z=-0.630,P=0.529).The baseline impedance of patients with grade LA C/D reflux esophagitis was 300 Ω (300 Ω,500 Ω),which was obviously lower than those of patients with grade LA-A or grade LA-B (Z=-2.647 and-2.818,both P＜0.017).Conclusion The baseline impedance of patients with reflux esophagitis is low and correlated with AET.

Background/Aims: Esophagogastric junction outflow obstruction (EGJOO) is characterized by elevated integrated relaxation pressure (IRP) and preserved esophageal peristalsis. The clinical significance of EGJOO is uncertain. This study aim to describe the clinical characteristics of these patients and to find out potential parameters to predict patients’ symptom outcome. Methods: Consecutive patients who received high-resolution manometry examination in our hospital in 2013-2019 and met the diagnostic criteria of EGJOO were retrospectively included. Motility and reflux parameters as well as endoscopy and barium esophagogram results were studied and compared. Patients were also followed up to record their treatment methods and symptom outcomes. Results: A total of 138 EGJOO (accounting for 5.2% of total patients taking high-resolution manometry examination in our hospital) patients were included. Only 2.9% of these patients had persistent dysphagia. A total of 81.8% of EGJOO patients had symptom resolution during follow-up. Patients with persistent dysphagia had significantly higher upright IRP (16.6 [10.3, 19.8] vs 7.8 [3.2, 11.5]; P = 0.026) than those without. Upright IRP can effectively distinguished patients with persistent dysphagia (area under curve: 0.826; P = 0.026) using optimal cut-off value of 9.05 mmHg. Conclusion EGJOO patients with persistent dysphagia and higher upright IRP (median > 9.05 mmHg) needs further evaluation and aggressive management.

Background/Aims: There is less acid burden in Chinese gastroesophageal reflux disease (GERD) patients. However, the Lyon consensus proposed a higher threshold of acid exposure time (AET > 6%) for GERD. The aims are to apply the updated criteria in Chinese GERD patients and clarify its influence on clinical outcome. Methods: Patients who were referred for both esophageal high-resolution manometry and 24-hour esophageal pH monitoring due to reflux symptoms were retrospectively screened. Those patients with AET > 4% was included and grouped into either AET 4-6% or AET > 6%. Their manometric profile, reflux profile, and response to proton pump inhibitors (PPIs) were evaluated. Adjunctive evidence proposed in the Lyon consensus was added in patients with AET 4-6% for therapeutic gain. Another group of patients (n = 144) with AET < 4% were included as non-GERD patients. Results: In total, 151 patients (102 males) were included with 113 patients AET > 6% (74.9%). GERD patients with AET > 4% were with more male, older patients, and higher body mass index compared with non-GERD patients. Meanwhile, GERD patients were less competent in esophagogastric junction pressure. However, the manometric and reflux profile were similar between patients with AET > 6% and 4-6%. The response rate of PPI therapy was 64.6% and 63.2%, respectively, in groups of AET > 6% and 4-6% (P > 0.05). When adjunctive evidence was added in patients with AET 4-6%, no therapeutic gain was obtained. Conclusions The efficacy of PPI therapy was similar in patients with AET > 6% and 4-6%. The increase of the AET threshold did not influence the clinical outcome of Chinese GERD patients.

Objective:To explore the effects of cognitive behavior therapy (CBT) combined with kinesitherapy on patients with functional dyspepsia (FD) .Methods:Totally 180 FD patients who attended the Department of Gastroenterology at the First People 's Hospital of Qinzhou were selected by convenient sampling and randomized divided into three groups according to the random number table: group A ( n=60) , which received conventional drugs to suppress acid, protect the stomach, regulate intestinal motility and combat anxiety; group B ( n=60) , which received CBT on the basis of routine treatment; group C ( n=60) , which received CBT combined with kinesitherapy on the basis of routine treatment. The Hamilton Anxiety Rating Scale (HAMA) , Hamilton Depression Rating Scale (HAMD) , and Gastrointestinal Quality of Life Index (GIQLI) were used to compare the anxiety, depression and quality of life among the three groups of patients. The treatment efficiency was also compared among the three groups. Results:After treatment, there was no statistically significant difference in HAMA scores among the three groups ( P>0.05) ; the HAMD score in group C was lower than that in groups A and B, and the GIQLI score was higher than that in groups A and B, with statistically significant difference ( P<0.05) . The total efficiency in group C was higher than that in groups A and B, but the difference was not statistically significant ( P>0.05) . Conclusions:CBT combined with kinesitherapy can alleviate the negative emotion and improve the life of quality in FD patients, which is worth promoting in clinical practice.
