Objective:To analyze the characteristics and electrogastrogram features of patients with functional dyspepsia (FD) overlapping lower gastrointestinal symptoms (LGS).Methods:The clinical data of 61 patients with FD from January 2018 to December 2020 in the First Affiliated Hospital of Nanjing Medical University were retrospectively analyzed. Among them, FD overlapping LGS was in 33 cases (FD overlapping LGS group), and simple FD in 28 cases (simple FD group). The manifestations of patients with FD overlapping LGS were recorded. The dyspeptic symptom score was assessed using the Rome Ⅳ criteria. Anxiety and depression status were evaluated using the hospital anxiety and depression scale (HADS), and sleep disorder was assessed using the Pittsburgh sleep quality index (PSQI). The electrogastrogram was performed, and the normal slow wave percentage (N%), bradygastria percentage (B%), tachygastria percentage (T%), arrhythmia percentage (A%), dominant frequency, dominant power and postprandial-to-fasting power ratio (PR) were recorded.Results:The most common symptom in FD patients overlapping LGS was lower abdomen distention, the incidence was 84.85% (28/33). The upper abdominal bloating score in FD overlapping LGS group was significantly higher than that in simple FD group: 7.00 (6.50, 7.00) scores vs. 5.00 (0.50, 7.00) scores, and there was statistical difference ( P<0.01); there were no statistical differences in other dyspeptic symptoms scores and total score between the two groups ( P>0.05). The incidences of depression and sleep disorder in FD overlapping LGS group were significantly higher than those in simple FD group: 42.42% (14/33) vs. 14.29% (4/28) and 69.70% (23/33) vs. 39.29% (11/28), and there were statistical differences ( χ2 = 5.77 and 5.68, P<0.05); there was no statistical difference in the incidence of anxiety between the two groups ( P>0.05). In FD overlapping LGS group, the postprandial T% in the gastric fundus and postprandial A% in the gastric body were significantly lower than those before meal: 13.79% (6.79%, 21.46%) vs. 20.69% (12.45%, 27.59%) and 3.45% (0, 6.90%) vs. 6.90% (3.45%, 13.79%), and there were statistical differences ( P<0.01). In simple FD group, the postprandial N% in the gastric fundus was significantly lower than that before meal: 55.92% (43.71%, 70.02%) vs. 69.27% (48.07%, 78.45%), and there was statistical difference ( P<0.05). In the gastric fundus, the preprandial N% in FD overlapping LGS group was significantly lower than that in simple FD group, preprandial B% and T% were significantly higher than those in simple FD group, and there were statistical differences ( P<0.01 or <0.05). In the gastric body, the preprandial N% in FD overlapping LGS group was significantly lower than that in simple FD group, and there was statistical difference ( P<0.05). In the pyloric region, the PR in FD overlapping LGS group was significantly lower than that in simple FD group, and there was statistical difference ( P<0.05). In the overall stomach, the preprandial N% in FD overlapping LGS group was significantly lower than that in simple FD group, the preprandial B% and T% were significantly higher than those in simple FD group, and there were statistical differences ( P<0.01 or <0.05). Spearman correlation analysis result showed that the disease course was not correlated with electrogastrogram parameters in patients with FD overlapping LGS ( P>0.05); the total score of dyspeptic symptoms was positively correlated with postprandial A% in the overall stomach ( r = 0.345, P<0.05), and negatively correlated with postprandial dominant frequency in the overall stomach and pyloric region ( r = -0.357 and -0.473, P<0.05 or <0.01). Conclusions:FD patients can overlap with various LGS. The patients with FD overlapping LGS have more severe dyspepsia symptoms, higher proportions of comorbid depression and sleep disorders, and more severe abnormalities in fasting proximal gastric electrical rhythm and emptying function. The severity of dyspeptic symptoms in patients with FD overlapping LGS is correlated with postprandial gastric electrical rhythm abnormalities.

Objective:To investigate the significance of small intestinal manometry in clinical diagnosis and treatment of patients with gastrointestinal motility disorders.Methods:The clinical data of 20 suspected patients with gastrointestinal motility disorders from February 2019 to January 2020 in Shanghai Jiaotong University Affiliated Ninth People′s Hospital were retrospectively analyzed. All patients were performed small intestinal manometry, and the influence on diagnosis and treatment as well as the clinical value of this technique were analyzed.Results:Among the 20 patients, 18 patients successfully accepted small intestinal manometry. Among the 18 patients, 14 patients showed significant motility abnormalities, among which 9 patients showed significant nutritional improvement after treatment and 5 patients were treated with maintaining nutritional support. In 10 patients, small intestinal manometry served as a deciding diagnostic tool, and in 12 patients, major modifications of treatment strategy were made according to results of small intestinal manometry.Conclusions:The small intestinal manometry significantly improves diagnosis and treatment decision in the patients with gastrointestinal motility disorders and shows great value on the clinical practice on this group of patients.

Objective:To investigate the clinical characters of enteric dysmotility (ED), in order to improve clinical diagnosis and treatment capabilities.Methods:The clinical data of 13 ED patients underwent small intestinal manometry from August 2019 to July 2022 in the Shanghai Jiaotong University Affiliated Ninth People′s Hospital and the Fourth Affiliated Hospital of Nanjing Medical University were retrospectively analyzed, including the clinical manifestation, small intestinal manometry result, treatment and prognosis.Results:Among 13 patients, 1 abnormality was presented in 9 cases, 2 abnormalities presented in 2 cases and 3 abnormalities presented in 2 cases. All 13 cases presented a history of constipation, 5 cases started with constipation and underwent subtotal colectomy. Three patients showed severe chronic abdominal pain with one of them opiate dependence. Eight patients underwent surgical treatment, all of which achieved nutritional improvement and symptom relief.Conclusions:ED is a concisely defined disease with clear diagnostic criteria. The surgery can increase the symptoms of some patients.

Objective:To investigate the safety and short-term efficacy of laparoscopic Nissen fundoplication in the treatment of refractory gastroesophageal reflux disease (rGERD).Methods:The clinical data of 61 patients underwent laparoscopic Nissen fundoplication from March 2018 to March 2022 in Jiangyin People′s Hospital were retrospectively analyzed. Among them, 14 patients had significant symptom relief after using proton pump inhibitor (PPI) before operation (group A), 30 patients had partial symptom relief after using PPI (group B), and 17 patients had persistent symptoms despite regular treatment with double-dose PPI for more than 8 weeks (group C). The surgical outcomes and recovery were compared among the three groups.Results:For the 61 patients, the surgical time was (117.46 ± 28.50) min, the intraoperative blood loss was 23.00 (8.00, 34.00) ml, and the postoperative hospital stay was 3.00 (2.00, 5.00) d. There were no statistically significant differences in surgical time, intraoperative blood loss, postoperative hospital stay, concurrent hiatal hernia repair and mesh placement among the three groups ( P>0.05). No short-term severe complications such as abdominal bleeding, abdominal infection and gastrointestinal perforation occurred in any group. There were no statistical differences in satisfaction score, subjective relief of overall postoperative symptoms, reflux symptoms, PPI usage, dysphagia, abdominal distention, diarrhea or constipation among the three groups ( P<0.05). No upper abdominal pain, recurrence and reoperation occurred in the three groups. Conclusions:Laparoscopic Nissen fundoplication has a definite therapeutic effect on rGERD, with significant anti reflux effects. There are no serious complications after surgery, and there are no recurrence or reoperation.

Objective:To analyze the effect of montelukast combined with budesonide in the treatment of children with intermittent asthma, and the impact on airway remodeling and T helper type 1 (Th1)/T helper type 2 (Th1/Th2) related cytokines.Methods:A prospective study was conducted among 120 children with intermittent asthma admitted to Huanghua Municipal People′s Hospital from December 2021 to February 2023. The children were randomly divided into the control group (60 children treated with budesonide atomizationinhalation) and the observation group (60 children treated with montelukast on the basis of the treatment of control group). Clinical efficacy, airway remodeling indicators [total area of airway (Ao), outer diameter of airway (D) and wall area to total airway cross-sectional area (WA%)], pulmonary function [peak expiratory flow (PEF), forced expiratory volume in 1 second (FEV 1)/forced vital capacity (FVC) and the maximum expiratory flow at 25% of vital capacity (MEF25%)], Th1/Th2 related cytokines, inflammatory factors [tumor necrosis factor-α (TNF-α), interleukin-4 (IL-4), interleukin-6 (IL-6) and interferon-gamma (IFN-γ)], recurrence, and the incidence of adverse reactions were compared between the two groups. Results:The total effective rate in the observation group was higher than that in the control group: 90.00% (54/60) vs. 75.00% (45/60) ( P<0.05). After treatment, Ao, D and WA% in the observation group were lower than those in the control group: (17.58 ± 1.89) mm 2 vs. (19.22 ± 1.94) mm 2, (4.25 ± 0.48) mm vs. (4.48 ± 0.49) mm, (63.75 ± 6.49)% vs. (69.22 ± 7.14)% ( P<0.05). PEF, FEV 1/FVC and MEF25% in the observation group were higher than those in the control group: (3.13 ± 0.34) L/s vs. (2.86 ± 0.35) L/s, (87.45 ± 8.86) % vs. (83.59 ± 8.42) %, (87.63 ± 8.86)% vs. (82.15 ± 8.43)% ( P<0.05). The levels of Th1 and Th1/Th2 in the observation group were higher than those in the control group: (14.13 ± 1.46) % vs. (10.27 ± 1.25) %, 3.46 ± 0.39 vs. 1.88 ± 0.25, and the level of Th2 was lower than that in the control group: (3.96 ± 0.45)% vs. (5.48 ± 0.56)% ( P<0.05). After treatment, the levels of TNF-α and IFN-γ in the observation group were higher than those in the control group: (76.15 ± 7.78) ng/L vs. (66.38 ± 6.47) ng/L, (7.15 ± 0.74) ng/L vs. (6.14 ± 0.66) ng/L. The levels of IL-4 and IL-6 were lower than those in the control group: (77.85 ± 7.96) ng/L vs. (86.42 ± 8.74) ng/L, (37.25 ± 3.89) mg/L vs. (44.23 ± 4.57) mg/L ( P<0.05). The recurrence rate in the observation group was lower than that in the control group: 3.33% (2/60) vs. 15.00% (9/60) ( P<0.05). The incidence rates of adverse reactions in the two groups were without statistically significant difference between the groups ( P>0.05). Conclusions:Montelukast combined with budesonide can reduce airway remodeling in children with intermittent asthma, improve their pulmonary function, Th1/Th2 related cytokines and inflammatory response indicators, and reduce recurrence rate, with good safety.

Objective:To investigate the value of peripheral blood platelet to gamma-glutamyl transferase ratio (PLT/GGT) in evaluating plaque stability recognized by virtual histology-intravascular ultrasound (VH-IVUS) in patients with coronary heart disease.Methods:This study was a prospective study. A total of 100 patients with coronary heart disease admitted in Zhejiang Veteran Hospital/the Third Affiliated Hospital of Jiaxing University from June 2020 to December 2022 were included. They were divided into vulnerable plaque group (42 cases) and stable plaque group (58 cases) based on the stability of the plaque examined by VH-IVUS. The general data, PLT/GGT and other laboratory indexes were compared between the two groups. The relationship between PLT/GGT and plaque stability in peripheral blood of patients with coronary heart disease and the evaluation value of PLT/GGT on plaque stability were analyzed.Results:The levels of C-reactive protein (CRP) and gamma-glutamyl transferase (GGT) in the vulnerable plaque group were higher than those in the stable plaque group: (8.07 ± 1.85) mg/L vs. (7.23 ± 1.57) mg/L, (72.39 ± 10.85) U/L vs. (67.13 ± 8.57) U/L, and PLT, PLT/GGT levels were lower than those in the stable plaque group: (180.76 ± 11.75) × 10 9/L vs. (187.36 ± 12.47) × 10 9/L, 2.55 ± 0.42 vs. 2.84 ± 0.41, the differences were statistically significant ( P<0.05). Point two column correlation found that the plaque stability recognized by VH-IVUS in patients with coronary heart disease was related to CRP, GGT, PLT, PLT/GGT ( P<0.05). Receiver operating characteristic curve analysis showed that the area under the curve (AUC) for assessing plaque stability using the peripheral blood PLT/GGT in patients with coronary heart disease was 0.71, which had certain evaluation value. Conclusions:The peripheral blood PLT/GGT in patients with coronary heart disease is closely related to the plaque stability recognized by VH-IVUS, and can be used as an effective indicator for evaluating plaque stability in patients.

Objective:To investigate the relationship between intestinal flora and acute respiratory distress syndrome in patients with severe acute pancreatitis.Methods:One hundred and six patients with severe acute pancreatitis admitted to a hospital from March 2019 to February 2021 were selected as the observation group for prospective analysis. They were divided into concurrent group (52 cases) and non-concurrent group (54 cases) according to whether they were complicated with acute respiratory distress syndrome. In addition, 100 healthy people in the same period were selected as the control group to analyze the relationship between intestinal flora and acute respiratory distress syndrome in patients with severe acute pancreatitis.Results:There were significant differences in the number of intestinal flora ( Lactobacillus, Bifidobacterium, Escherichia coli) between the observation group and the control group ( t = 49.69, 73.28 and 46.32; P<0.05). There were significant differences in the number of intestinal flora ( Lactobacillus, Bifidobacterium, Escherichia coli) between the concurrent group and the non-concurrent group ( t = 34.85, 39.71 and 23.47; P<0.05). The levels of serum endotoxin, diamine oxidase and D-lactic acid in the concurrent group were significantly higher than those in the non-concurrent group: (0.63 ± 0.16) EU/ml vs. (0.45 ± 0.08) EU/ml, (6.29 ± 1.18) U/ml vs. (4.89 ± 0.91) U/ml, (11.63 ± 2.84) mmol/L vs. (9.33 ± 2.61) mmol/L ( t = 7.37, 6.85 and 4.34, P<0.05). Spearman analysis showed that severe acute pancreatitis complicated with acute respiratory distress syndrome was negatively correlated with the number of intestinal Lactobacillus and Bifidobacterium ( r = - 0.342 and - 0.291, P = 0.011 and 0.021), which was positively correlated with the number of intestinal Escherichia coli flora ( r = 0.263, P = 0.033). Conclusions:Intestinal colony imbalance is common in patients with severe acute pancreatitis, and the imbalance of intestinal colony and the impairment of intestinal mucosal barrier function are more serious in patients with acute respiratory distress syndrome. There is a significant correlation between severe acute pancreatitis complicated with acute respiratory distress syndrome and its intestinal colony.

Objective:To analyze the risk factors of postoperative infection in patients with colon cancer, and construct a nomogram model.Methods:The clinical data of 220 patients with colon cancer in Anhui Cancer Hospital from May 2019 to June 2022 were retrospectively analyzed. Among them, 55 patients developed postoperative infection (infection group), and 165 patients did not develop postoperative infection (non-infection group). The receiver operating characteristic (ROC) curve was used to analyze the efficacy of each index in predicting postoperative infection in patients with colon cancer. Multivariate Logistic regression analysis was used to analyze the independent risk factors of postoperative infection in patients with colon cancer. R language 3.5.2 software was used to construct a nomogram model for predicting postoperative infection in patients with colon cancer, and it was verified and evaluated.Results:There were no significant differences in gender composition, body mass index, tumor stage, intraoperative blood transfusion, hypertension, smoking history, alcohol consumption history, tumor diameter and hemoglobin between the two groups ( P>0.05); the age, diabetes mellitus ratio, operation time and exhaust time in the infection group were significantly higher than those in the non-infection group: (49.60 ± 4.40) years old vs. (47.20 ± 4.12) years old, 63.64% (35/55) vs. 30.30% (50/165), (197.80 ± 12.55) min vs. (192.23 ± 12.05) min and (3.42 ± 1.18) d vs. (2.60 ± 0.80) d, the albumin was significantly lower than that in the non-infected group: (28.29 ± 3.02) g/L vs. (32.80 ± 3.21) g/L, and there were statistical differences ( P<0.01). ROC curve analysis result showed that the area under the curve of age, operation time, exhaust time and albumin for predicting postoperative infection in patients with colon cancer were 0.672, 0.610, 0.706 and 0.846, and the optimal cut-off values were 49 years old, 184 min, 3 d and 30 g/L, respectively. Multivariate Logistic regression analysis result showed that age (>49 years old), diabetes mellitus, operation time (>184 min), exhaust time (>3 d) and albumin (≤30 g/L) were independent risk factors of postoperative infection in patients with colon cancer ( OR = 2.131, 1.758, 1.449, 1.841 and 2.325; 95% CI 1.269 to 2.696, 1.354 to 3.059, 1.201 to 1.965, 1.018 to 2.365 and 1.582 to 3.051; P<0.01). A nomogram model was constructed with age, diabetes mellitus, operation time, exhaust time, and albumin as predictors for predicting postoperative infection in patients with colon cancer. The correction curve of the nomogram model for predicting postoperative infection in patients with colon cancer was close to the ideal curve (C-index = 0.764, 95% CI 0.657 to 0.834); decision curve analysis result showed that the nomogram model provided clinical net benefit when the risk threshold was > 0.07; and the clinical net benefit of the model was higher than that of age, diabetes mellitus, operation time, exhaust time and albumin. Conclusions:The age (>49 years old), diabetes mellitus, operation time (>184 min), exhaust time (>3 d) and albumin (≤30 g/L) are the independent risk factors of postoperative infection in patients with colon cancer, and the nomogram model based on the above variables could predict postoperative infection.

Objective:To analyze the clinical curative effects of wire-to-port drainage and put-aside drainage after incision and hanging on perianal abscess.Methods:Eighty-two patients with perianal abscess admitted to Anqing Municipal Hospital between November 2019 and November 2022 were enrolled. The patients were divided into group A (41 cases, incision and hanging wire-to-port drainage) and group B (41 cases, incision and hanging put-aside drainage) by random digits table method. The clinical curative effect, operation time, wound healing time, postoperative recovery time and hospitalization time in the two groups were compared. The pain and anal function were evaluated by visual analogue score (VAS) and Wexner continence grading score (Wexner score) before surgery and 1, 7 d after surgery. The occurrence of complications within 1 month after surgery was statistically analyzed.Results:There was no significant difference in total clinical response rate between group A and group B ( P>0.05). There was no significant difference in operation time between the two groups ( P>0.05). The wound healing time, postoperative recovery time and hospitalization time in group A were significantly shorter than those in group B: (21.34 ± 2.21) d vs. (27.86 ± 2.84) d, (23.12 ± 2.42) d vs. (28.36 ± 2.91) d, (8.12 ± 0.83) d vs. (13.25 ± 1.47), P<0.05. At 1 and 7 d after surgery, the VAS and Wexner score in group A were lower than those in group B: (6.11 ± 0.62) points vs. (6.54 ± 0.67) points, (2.39 ± 0.25) points vs. (3.21 ± 0.33) points, (7.54 ± 0.77) points vs. (8.96 ± 0.91) points, (4.22 ± 0.43) points vs. (5.68 ± 0.58) points, P<0.05. There was no significant difference in total incidence of complications between the two groups within 1 month after surgery ( P>0.05). Conclusions:Compared with incision and hanging put-aside drainage, incision and hanging wire-to-port drainage can promote wound healing, shorten hospitalization time, relieve postoperative pain and improve anal function in patients with perianal abscess, with certain safety.
