Objective To summarize the experience of early management in elderly patients with serious burning in order to raise cure rate. Methods Elderly patients (63 cases) with serious burning (burned area exceeding 30% or Ⅲ? area exceeding 10% ) admitted from 1990 to 2002 were retrospectively studied. Patients were divided into two groups according to the admission date, before and after January 1, 1996 since new management was extensively applied after 1996. These measures consisted of rapid and adequate fluid resuscitation, early enteral feeding and autograft after eschar excision. Results The incidence of sepsis and MODS was 38.7% and 19.4% respectively after 1996. It was evidently lower than the group before 1996(65.6% vs 43.8%, P

Blood glucose level responses to different diets were examined in 12 healthy man. The test breakfasts consist of different proportion of protein and carbohydrate. Three kinds of test breakfast were fed respectively for each person. Blood glucose were measured before and 1, 2 and 4 hr after breakfast. The results indicated that high-CHO diet maintained higher level of blood glucose than other diets in 1-2 hr after breakfast. However the blood glucose level began dropping from 2 hr and dropped below fasting level at 4 hr after breakfast. The high-protein diet resulted in decreasing of blood glucose level in 1-2 hr after breakfast. The blood glucose level then increased continuously until 4 hr after breakfast.The results in this experiment showed that adjustment of the proportion of carbohydrate and protein in diets could maintain the blood glucose to a higher and stable level.

Objective To explore the possible effects of nutritional supplements on brain function as reflected by Water Maze test performance in mice after +Gz exposure.Method Mice were arranged into control group (group A),+Gz group without nutritional supplementation (group B) and +Gz plus nutritional supplementation group (group C).Each group contains 12 mice.Mice in group A were not exposed to +Gz while mice in both group B and group C were exposed to 8 min +10 Gz.Distilled water was gavaged to group B mice 3 h before +Gz exposure.On the day before +Gz exposure pyridoxol fortified water was given and 3 h before exposure mixed amino acids solution were gavaged to group C mice.Water Maze test was done and scores were recorded in all groups.After the Water Maze test was completed,blood was collected through the eyes for serum amino acid determinations and brain tissue was collected by decollation for monoamine determination and γ-glutamyl transferase (GGT) activity evaluation. Result After +Gz exposure,longer completion time and more mistakes were observed in Water Maze test in group B as compared with group A and a trend of improvement in group C was noticed. The ratio of brain 5-HT to dopamine(DA) was significantly reduced in group C as compared with group B.Gamma glutamyl transferase (GGT) activity in brain tissue in group C and group B increased significantly. Conclusion High sustained +Gz exposure significantly reduces Water Maze test performance in mice (longer completion time and more mistakes).It seems that there is a trend of improvement in Water Maze performance in mice in dietary nutritional supplementation group,which might be due to significant reduction in ratio of brain 5-HT to DA in mice with nutritional supplementation.

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 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 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.

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.
