Objective:To investigate the regulation of intestinal microbiota by Roux-en-Y gastric bypass (RYGB) on patients with obesity or obesity combined with diabetes.Methods:The retrospective and descriptive study was conducted. The stool samples before and after surgery and clinical data of 20 patients with obesity, including 9 simple obesity cases and 11 obesity combined with diabetes cases, who underwent RYGB in the First Affiliated Hospital of Ji′nan University from July 2016 to August 2017 were collected. There were 11 males and 9 females, aged (33±11)years. Observation indicators: (1) changes in composition and structure of intestinal microflora; (2) changes of intestinal microflora in simple obesity patients after operation; (3) changes of intestinal microflora in obesity combined with diabetes patients after operation. Follow up was conducted using telephone interview or outpatient examinations to detect the body mass, the application of antimicrobial agent and the blood glucose control of patients. According to the unified training points, the stool samples were collected and stored into the DNA stabilizer, and then conducted to laboratory analysis within 45 hours. The follow up was up to November 2018. Measurement data with normal distribution were represented as Mean± SD, and independent-samples t test was used for inter-group comparison and paired-samples t test was used for intra-group comparison. Measurement data with skewed distribution were represented as M( Q1, Q3), and Wilcoxon signed rank test of two independent samples was used for inter-group comparison. Count data were described as absolute numbers, and the chi-square test, ANOSIM analysis, linear discriminant (LEfSe) analysis and the Metastats analysis were used for inter-group comparison. Results:(1) Changes in composition and structure of intestinal microflora. The Shannon index of α diversity of preoperative intestinal microflora in simple obesity patients and obesity combined with diabetes patients was 4.37±0.69 and 4.47±0.85, respectively, showing no significant difference between them ( t=0.28, P>0.05). Results of preoperative LEfSe analysis showed that there were differences in the bacterial abundance of Firmicutes and Bacteroidea between simple obesity patients and obesity combined with diabetes patients. The abundances of Parasutterella in simple obesity patients and obesity combined with diabetes patients was 0.000 113 0(0, 0.004 378 2) and 0.008 464 0(0.001 325 7, 0.034 983 1), respectively, showing a significant difference between them ( Z=2.12, P<0.05). Results of preoperative PCoA analysis showed that the contribution rates of principal component 1, principal component 2 and principal component 3 were 24.98%, 22.24% and 16.33% in simple obesity patients and obesity combined with diabetes patients and results of ANOSIM comparison showed that there was no significant difference in preoperative intestinal microflora between them ( r=?0.11, P>0.05). The Shannon index of α diversity of postoperative intestinal microflora in simple obesity patients and obesity combined with diabetes patients was 4.60±0.65 and 4.66±0.40, respectively, showing no significant difference between them ( t=0.24, P>0.05). Results of postoperative LEfSe analysis showed that there were differences in the bacterial abundance of Bacteroidea, Proteus and Firmicutes between simple obesity patients and obesity combined with diabetes patients. The abundances of Morganella and Coprococcus_2 in simple obesity patients and obesity combined with diabetes patients were 0.000 192 0(0.000 011 9,0.001 569 0), 0(0,0) and 0(0,0), 0.000 054 1(0,0.000 419 0), showing significant differences between them ( Z=2.70, 2.29, P<0.05). (2) Changes of intestinal microflora in simple obesity patients after operation. There were 10 genera of bacteria of intestinal bacteria changing after surgery, including 7 species of bacteria increasing in the Firmicutes and the Proteobacteria as Veillonella, Morganella, Granulicatella, Aeromonas, Streptococcus, Rothia and Megasphaera and the bacteria decreasing in the Firmicutes and the Actinobacteria as Ruminococcus_torques_group, Romboutsia and Erysipelo-trichaceae_UCG-003. Results of LEfSe analysis showed that the bacteria significantly enriched in simple obesity patients before surgery were Ruminococcus_torques_group, Romboutsia and Erysipelotri-chaceae_UCG-003, belonging to Firmicutes, and the bacteria significantly enriched in simple obesity patients after surgery were Rothia, Granulicatella, Enterococcus, Streptococcus, Megasphaera, Veillonella, A eromonas and Morganella, belonging to Actinobacteria, Firmicutes and Proteobacteria. (3) Changes of intestinal microflora in obesity combined with diabetes patients after operation. There were 16 bacteria of intestinal bacteria increasing after surgery, including Streptococcus, Veillonella, Haemophilus, Pluralibacter, Gemella, Lachnospiraceae_NC2004_group, Granulicatella,Aeromonas, uncultured_ bacterium_f_ Saccharimonadaceae, R uminiclostridium_9, Butyricicoccus, Fusobacterium, Anaerotruncus, Fusicateni-bacter, Klebsiella and E ubacterium_eligens_group, which belonged to the Firmicutes and the Proteo-bacteria. Results of LEfSe analysis showed that the bacteria significantly enriched in obesity combined with diabetes patients before surgery were Fusicatenibacter, Tyzzerella_3 and Butyricicoccus, belonging to the Firmicutes, and the bacteria significantly enriched in obesity combined with diabetes patients after surgery were Gemella, Granulicatella, Enterococcus, Streptococcus, Lachnospiraceae_NC2004_group, Eubacterium_eligens_group, Anaerotruncus, Ruminiclostridium_9, Anaeroglobus, Veillonella, Fusobacterium, uncultured_bacterium_f_Saccharimonadaceae, Aeromonas, Klebsiella, Pluralibacter, Proteus and Haemophilus, belonging to the Firmicutes and the Proteobacteria. Conclusions:RYGB can significantly increases the intestinal microflora abundance in simple obesity patients and obesity combined with diabetes patients. The two types of patients have specific changes in intestinal microflora at the genus level.

Objective:To evaluate the effect of inhaled medication compliance intervention in elderly patients with chronic obstructive pulmonary disease (COPD) based on integrated theory of health behavior change.Methods:A total of 117 elderly COPD patients who visited Respiratory Department of Beijing Chaoyang Hospital Affiliated to Capital Medical University from July to December 2021 were selected by the convenient sampling method. According to the random number table method, they were divided into the experimental group and the control group. 7 cases fell off during follow-up, and a total of 110 cases were finally included in the study, of which 55 cases were in the experimental group and 55 cases in the control group. The control group adopted the conventional health education method, while the experimental group adopted the intervention plan of inhalation medication compliance of elderly COPD patients based on the integrated theory of health behavior change. The accuracy of inhalation device use, inhalant medication compliance, forced expiratory volume in the first second (FEV 1) and Chronic Obstructive Pulmonary Diseases Assessment Test (CAT) scores were compared between the two groups before intervention and 3 months after intervention. Results:After 3 months of intervention, the inhalation device use accuracy, inhalation medication compliance in experimental group were higher than those in the control group, the score of CAT in experimental group was lower than that in the control group, the differences were statistically significant ( P<0.05). There was no statistically significant difference in FEV 1 between two groups ( P>0.05) . Conclusions:The intervention plan for inhalation medication compliance in elderly patients with chronic obstructive pulmonary disease based on the integrated theory of health behavior changes can improve their inhalation medication compliance and improve their quality of life.

Objective:To discuss how to avoid the occurrence of adverse events and provides basis for improving the extracorporeal membrane oxygenation (ECMO) transport safety management to formulate the corresponding preventive measures through analyzing the causes and characteristics of adverse events in transport of ECMO.Methods:By using a self-designed ECMO transport observation table to collect data, with a retrospective study of adverse events in patients with ECMO transport in ECMO center of Beijing Chaoyang Hospital from January 2013 to June 2017, carrying out classification and analysis according to the causes of adverse events and the potential risks of the patients, thus put forward the feasible preventive measures.Results:There were 53 cases of ECMO transport in study period, with 18 cases (33.96%) of adverse events, among which the incidence of adverse events in inner-hospital transport was 34.21% (13/38) and that in inter-hospital transport was 33.33% (5/15). There was no patient died in ECMO transport. In the adverse events of ECMO transport, the main causes were related to transport staff, transport equipment and patient, which accounting for 1/3 of each. Among them, the most prominent was 4 cases (22.22%) of equipment lacking and 3 cases of battery and power supply (16.67%). In classification according to the risk degree of patients, 6 cases (33.33%) of third grade risk were found.Conclusions:It is safe and feasible to carry out ECMO transport in inner-hospital transport and inter-hospital transport based on ECMO transport team and transport process of this hospital. However the unexpected events of high risk or crisis of life is inevitable in ECMO transport. Through standardized training for ECMO team, with full assessment before transport, by the use of ECMO checklist and strict implementation of various transport processes and specifications, the incidence of adverse events in ECMO transport may be reduced.
