Objective:To evaluate the safety and efficacy of domestically produced magnetic sphincter augmentation (MSA) for gastroesophageal reflux disease.Method:This study is a prospective cohort study. Patients with typical heartburn and reflux symptoms (at least partial response to proton pump inhibitors), abnormal esophageal acid exposure and normal esophageal peristalsis were included, prospectively in the Department of Gastroesophageal Surgery, Rocket Force Characteristic Medical Center from June 2019 to September 2022. Patients with hiatal hernia >2 cm and severe esophagitis were excluded. The MSA was wrapped around the distal esophagus after esophageal hiatus repair by laparoscopy. A postoperative questionnaire survey was conducted to assess the relief of symptom, complications, the discontinuation rate of proton pump inhibitor, and surgical satisfaction. Gastroscopy, high-resolution esophageal pressure measurement, and pH value impedance monitoring were also reviewed. The pre- and postoperative rates were compared using the McNeinar χ2 test. Result:Currently, 23 patients with gastroesophageal reflux disease were enrolled and underwent MSA surgery. There were 20 males and 3 females, aged ( M (IQR)) 48 (14) years (range: 25 to 64 years). All cases were successfully implanted with MSA. Subjective indicators were followed for 17 (18) months (range: 14 to 53 months), while objective indicators were followed for 17 (1) months (range: 12 to 23 months). The postoperative gastrointestinal and extraesophageal symptom scores showed a significant decrease compared to preoperative levels as follows: the degree of subjective relief of overall digestive symptoms was 90 (20)% (range:0~100%), the degree of subjective relief of overall respiratory symptoms was 100(10)% (range: 10%~100%), the overall satisfaction rate was 83% (19/23), the proton pump inhibitor discontinuation rate was 70% (16/23). The proportion of esophagitis has decreased from 44% (10/23) to 9% (2/23) ( κ=0.169, P=0.039), The Hill grade of gastroesophageal valve morphology improved from 1 case of grade Ⅰ, 5 cases of grade Ⅱ, 10 cases of grade Ⅲ, and 7 cases of grade Ⅲ preoperative to 22, 1, 0, and 0 cases postoperative. The proportion of lower esophageal sphincter pressure below normal has decreased from 70% (16/23) to 35% (8/23) ( κ=0.170, P=0.012). There were 21 patients who restored normal esophageal acid exposure. Eleven patients had mild long-term dysphagia, but it didn′t affect their daily life. No postoperative device migration, erosion, or secondary surgical removal occurred. Conclusions:Laparoscopic implantation of the MSA device was safe and well tolerated. It can effectively control the symptoms of gastroesophageal reflux disease, reduce medication, restore normal cardia morphology and function, and esophageal acid exposure. The main postoperative complication was dysphagia, but it was relatively mild.

Objective:To explore the long-term efficacy of laparoscopic fundoplication for proton pump inhibitor dependent gastroesophageal reflux disease (GERD).Method:Clinical data of proton pump inhibitor dependent GERD patients who underwent fundoplication at the Rocket Force Characteristic Medical Center from Jan to Jun 2012 were analyzed, including GERD symptom score, subjective symptom relief rate, PPI discontinuation rate and surgical satisfaction, as well as recurrence and complications.Result:A total of 160 GERD patients were included in this study, with 64% of patients having respiratory symptoms. Nissen and Toupet fundoplication were performed in 43 and 117 cases, respectively, with a follow-up time of (127±3) months. The postoperative GERD symptom scores of the patients were significantly lower than before treatment (all P<0.001); The subjective relief of overall symptoms in the digestive tract and airway problem was 90% (80%, 100%) and 100%, respectively. The PPI discontinuation rate was 86%, and the overall satisfaction rate of the treatment was 92%, and the satisfaction rate of patients with respiratory symptoms was 89%. 7% of patients experienced varying degrees of symptomatic recurrence, 4% of patients re-underwent endoscopic treatment and/or laparoscopic fundoplication due to symptom recurrence. The incidence of long-term postoperative dysphagia, bloating, belching, increased exhaust, abdominal pain, diarrhea, and constipation were 11.3%, 16.9%, 0, 1.3%, 0, 2.5%, and 5.6%, respectively. Conclusions:Laparoscopic fundoplication has good long-term efficacy in the treatment of GERD. A small number of patients may experience postoperative recurrence, as well as complications such as dysphagia and gas-bloat syndrome. Most recurrent patients can achieve good therapeutic effect by redoing endoscopic treatment or redoing surgery.

Objective:To build a hospital bed resource allocation model, for the reference of public hospitals in optimizing their bed resource allocation.Methods:Based on ReLU activation function, a hospital bed resource allocation model was constructed by combining DRG and public hospital performance appraisal requirements, including discharge person times, average length of stay, hospital bed utilization rate, proportion of surgery, proportion of fourth level surgery, case mix index, average bed day income and other indicators. When the existing number of hospital beds available was greater than the number of hospital beds allocated for the first time, a secondary allocation should be made. A tertiary general hospital was taken as an example for a model analysis.Results:As found in the model analysis, among the 2 729 beds of the hospital in the first allocation, 110 beds were left available for secondary allocation. The results of bed allocation of 40 inpatient departments in the hospital were as follows: 15 departments need more beds, 3 departments need more beds and shorter length of stay, 2 departments need no change, 1 department needs shorter length of stay, 4 departments need less beds, and 15 departments need less beds and shorter length of stay.Conclusions:The bed resource allocation model enriches the connotation of indicators, reflects the specialty characteristics. These indicators can be flexibly adjusted in combination with hospital development planning and budget management, hence conducive to refined management of hospital bed resources in public hospitals.

Objective:To analyze the difference and clinical significance of reflux related parameters between patients with reflux asthma (RA) and typical gastroesophageal reflux disease (TGERD).Methods:From June 2017 to June 2020, at PLA Rocket Force Characteristic Medical Center, the clinical data of 120 patients with gastroesophageal reflux disease (GERD) who underwent gastroscopy, high-resolution esophageal manometry (HREM) and 24 h pH-impedance monitoring contemporaneously were retrospectively analyzed. The GERD patients were divided into RA group and TGERD group according to the symptom correlated indexes, 60 cases in each group. The reflux related indexes of two groups were compared, which included reflux esophagitis (RE) score, esophageal hiatal hernia, Hill grade score of gastroesophageal flap valve, upper esophageal sphincter (UES) pressure, DeMeester score, and reflux episodes. Mann-Whitney U test and chi-square test were used for statistical analysis. Results:There were no significant differences in RE score and Hill grade score between TGERD group and RA group (0.0, 0.0 to 1.0 vs. 0.0, 0.0 to 1.8; 3.0, 2.0 to 3.0 vs. 3.0, 2.0 to 3.0) (both P>0.05). The detection rate of UES pressure less than 34 mmHg (1 mmHg=0.133 kPa) of RA group was higher than that of TGERD group (41.7%, 25/60 vs. 23.3%, 14/60), and the difference was statistically significant ( χ2=4.596, P=0.032). The UES pressure of RA group was lower than that of TGERD group (51.7 mmHg, 23.6 mmHg to 70.1 mmHg vs. 62.0 mmHg, 37.4 mmHg to 77.4 mmHg), and the difference was statistically significant ( Z=-2.105, P=0.035). There were no significant differences in other parameters of HREM between TGERD group and RA group (all P>0.05). The detection rates of DeMeester score more than 14.7, acid exposure time more than 4.5% and total reflux episodes more than 73 episodes of RA group were all higher than those of TGERD group (41.7%, 25/60 vs. 23.3%, 14/60; 40.0%, 24/60 vs. 21.7%, 13/60; 38.3%, 23/60 vs. 20.0%, 12/60, respectively), and the differences were all statistically significant ( χ2=5.546, 4.728 and 4.881, all P<0.05). The total reflux episodes and weak acid gas reflux episodes of RA group were both higher than those of TGERD group (60 episodes, 43 episodes to 98 episodes vs. 52 episodes, 34 episodes to 69 episodes; 12 episodes, 6 episodes to 21 episodes vs. 9 episodes, 3 episodes to 14 episodes), and the differences were statistically significant ( Z=-2.323 and -2.053, both P<0.05). There were no significant differences in other parameters of 24 h pH-impedance monitoring between TGERD group and RA group (all P>0.05). Conclusion:Low UES pressure, abnormal esophageal acid exposure and increased reflux episodes, especially weak acid gas reflux episodes, may be more likely to induce RA.

Objectives To evaluate the effectiveness of cognitive behavior therapy for insomnia (CBT-i) in chronic insomnia patients in terms of the improvements of psychological and sleep diary parameters. Methods Patients who met the diagnostic criteria of chronic insomnia, were divided into primary group or comorbid group. Both groups received standard CBT-i interventions. Psychological scales and sleep diaries were used to evaluate participants' severity of insomnia and psychological conditions related to insomnia at four time points:before intervention (baseline), immediate after intervention, 4 weeks and 16 weeks after intervention. Results Both groups achieved significant improvements after intervention on psychological measurements and sleep diary parameters. Such improvements were maintained at 4-week and 16-week follow-ups. The sleep diary data indicated that by the end of the intervention, there were significant differences on sleep onset latency(51.72 min to 10.53 min in primary group, P<0.01;59.26 min to 15.67min in comorbid group, P<0.01)and sleep efficiency (71％to 95％in primary group, P<0.01;68％to 90％in comorbid group, P<0.01). There were differences on sleep onset latency (10.00 min vs. 13.93 min,P<0.05), total sleep time (355.71 min vs. 327.85 min, P<0.05) and sleep efficiency (95％vs. 91％, P<0.01) in primary group and comorbid group respectively. No differences were found on wake after sleep onset in the two groups. Conclusions Chronic insomnia patients with or without comorbidities both have improvements after CBT-i. Sleep diary parameters rather than psychological measurements are different in two groups. Thus, CBT-i is an effective non-pharmaceutical therapy inpatients with chronic insomnia.

Objective: To investigate the dynamic change of paraquant-induced kidney injury in rats and the protective effect of edaravone. Methods: Eighty SD rats were randomly divided into 4 groups: the normal control group, paraquat poisoning group, edaravone treatment group and edaravone control group. The normal control group of 8 rats were given 1 ml of 0.9% sodium chloride through the abdominal cavity, and the same amount of fluid into the abdominal cavity after 30 minutes. The paraquat poisoning group of 24 rats were given 1 ml of paraquat solution (20 mg/kg) through the abdominal cavity to build poisoning models, and the same amount of 0.9% sodium chloride was injected into the abdominal cavity after 30 minutes. The edaravone treatment group of 24 rats were given edaravone (5 mg/kg) through the abdominal cavity after 30 minutes when the poisoning models were set up. The edaravone control group of 24 rats were given 1 ml of 0.9% sodium chloride through the abdominal cavity, and edaravone (5 mg/kg) was injected into the abdominal cavity after 30 minutes. In addition to the normal control group, the other groups processed 1 times a day to mantain 7 d. On 1, 3, 7, 21 d several rats in each group were excuted and the kidney tissue and serum samples were collected, then each pathological changes of the kidney were observed with light microscopy. Serum creatinine, KIM-1, NGAL were measured by ELISA, the expression of HSP70 protein in kidney were observed with immunohistochemical staining. Results: The pathological examination reveald that the damage of kidney tissue in the paraquat group was the most serious on 3 d, and the damage was consistently alleviated in edaravone treatment group at the same time, renal fibrosisn was unseen in each group until 21 d. Compared with normal control group, there was no statistically significant in edaravone control group (P>0.05) . The KIM-1 in blood and kidney in paraquat poisoning group were markedly increased in 1 d (P<0.05) . The NGAL in blood and creatinine were markedly increased in d7 (P<0.05) . The NGAL in kidney increased over time, but had no statistically difference with the control group (P>0.05) .Compared with paraquat poisoning group, the serum creatinine, KIM-1 in blood and kidney, the KIM-1 in kidney had decreased significantly in edaravone treatment group (P<0.05) . The NGAL in kidney has no statistically significant compared with the poisoning group (P>0.05) . HSP70 expression of kidney tissue in edaravone treatment group had significantly increased in d3 compared with the paraquat poisoning group (P<0.05) . Conclusion Edaravone can prompt a significant rise of HSP70 in kidney tissue, reduce KIM-1 and NGAL levels, and play a protective role in kidney injury of acute paraquat poisoning.
