Totally 8 480 elderly inpatients hospitalized in the Department of Internal Medicine from 1 June 2020 to 31 May 2021 in Chenzhou NO. 1 People′s Hospital were selected by convenient sampling as the control group, and 8 662 elderly inpatients hospitalized in the Department of Internal Medicine from 1 June 2021 to 31 May 2022 were in the experimental group. The routine fall prevention measures were used in the control group, and on this basis, the experimental group formulated and implemented fall prevention management strategies involving patients based on the patient participation framework "informing, participating, empowering, cooperating, and electronic information support" and introduced Internet plus. Then the differences between the two groups in terms of the incidence of falls and the satisfaction rate of nursing care were compared.Results:The experimental group included 8 662 cases (5 110 males and 3 552 females) with (73.96 ± 8.78) years old, while the control group included 8 480 cases (4 918 males and 3 562 females) with (74.11 ± 8.59) years old. The incidence of falls in experimental group (0.092%, 8/8 662) was lower than that in control group (0.224%, 19/8 480), and the difference was statistically significant ( χ 2=4.71, P<0.05); the nursing care satisfaction rate of experimental group (98.880%, 8 565/8 662) was higher than that of control group (96.450%, 8 179/8 480), and the difference also was statistically significant ( χ 2=106.50, P<0.01); the analysis of the fall causes of the patients revealed that the toilet squatting commode was an important hidden risk of falls in elderly patients. Conclusions:Fall prevention management strategies based on patient participation can reduce the incidence of falls in elderly patients and improve the satisfaction rate of nursing care. Patient participation introduced "Internet plus" can prevent patient falls. The root causes of patient falls will continue to change, and care managers should continually track real-time changes in the root causes of falls to identify problems, develop and adjust prevention strategies accordingly, and pay attention to the importance of infrastructure in the safety of older patients.

Objective:To explore the effects of standard meal and treadmill exercise test on body surface gastrointestinal electrogram in healthy subjects, and to provide more evidence for the clinical application of gastrointestinal electrogram.Methods:From January to June 2021, a total of 100 healthy asymptomatic volunteers underwent gastrointestinal electrogram after fasting, standard meal and treadmill exercise test. After the subjects fasted for more than 8 hours, the gastrointestinal electrogram was performed after the subjects were lying flat, quiet, and breathing steadily, electrodes were placed on the the body surface projection positions of the gastric body, the lesser curvature, the greater curvature, the antrum, the ascending colon, the transverse colon, the descending colon, and the rectum. The fasting gastrointestinal electrogram was recorded for 6 min. Then lay for 5 to 10 min after the standard meal (100 g bread, 250 mL milk), the postprandial gastrointestinal electrogram was recorded for 6 min. And lay for 5 to 10 min after treadmill exercise test, then the postexercise gastrointestinal electrogram was recorded for 6 min. The frequency and amplitude of gastrointestinal electrogram waveforms of the three time points were compared, and the percentage of gastrointestinal electrical rhythm disorder, and slow wave frequency instability coefficient were also compared. Stratified analysis of gastric motility was performed according to age, sex and body mass index. Paired t-test, Pearson Chi-squared test, continuity correction Chi-squared test, Fisher′s exact method and Speraman correlation were used for statistical analysis. Results:The standard meal did not obviously affect the mean frequency of the gastric electrocardiogram, however the mean amplitude of gastric electrocardiogram significantly increased after standard meal compared with that of fasting, especially in the electrodes placed at lesser curvature((148.5±8.7) μV vs.(113.2±5.0)μV ), greater curvature((176.3±11.3) μV vs.(126.1±7.3) μV), and antrum((161.8±10.6) μV vs.(117.6±4.91) μV), and the differences were statistically significant( t=4.63, 4.63 and 3.99, all P< 0.001).

RESUMEN
[Summary] To explore the therapeutic effect of fecal microbiota transplantation (FMT) for severe psoriasis. A patient, male, 36 years old, diagnosed as severe plaque psoriasis for 10 years and irritable bowel syndrome (IBS) for 15 years, was administrated twice FMT via both upper endoscopy and colonoscopy with a 5‐week interval. The following items were used to evaluate responses: body surface area (BSA), psoriasis area and severity index (PASI), dermatology life quality index (DLQI), histological examination, intestinal symptoms, adverse reactions and serum level of tumor necrosis factor (TNF)‐α. After second FMT treatment for 5 weeks, aforementioned items were improved greatly compared with those before treatment. Moreover, IBS was completely relieved and no adverse reactions were observed during the treatment and follow‐up. In conclusion, FMT could be a novel therapy for psoriasis. Further clinical trials are needed to provide solid evidences.

RESUMEN
Objective To evaluate the feasibility and safety of the robot - assisted system YunSRobot for remote manipulation endoscopy. Methods When the master of YunSRobot was installed in the gastroenterology office in Chinese PLA General Hospital, the robot slave and upper gastrointestinal simulation model (Takahashi Lm103,Japan) were installed at the same time in the State Key Laboratory of Robotics, Shenyang Institute of Automation. Three physicians were trained to operate the master robotics and performed gastroscopy on the simulation model based on network cloud. Each physician performed 3 procedures of oesophagogastroduodenoscopy (EGD) by YunSRobot using traditional manual endoscopy, on-site operating mode, and remote manipulation mode, respectively. The operating time, lumenal anatomic exposure,man-machine interaction and other parameters were recorded. Results The number of standard pictures obtained by traditional manual endoscopy group, on-site operating group and remote manipulation group were 39.9±0.3, 39.8±0.4, 39.9±0.3, respectively. The images of all five lesions could be obtained by each operation. The operating time in the duodenum of remote group was longer than that of on-site group, with average time (78.2±16.0)s vs. (68.9±15.8)s (P=0.021) respectively. As to the operating time on other parts or total time, all three groups were comparable. Although there was a mean delay of (572.1±48.5) ms in remote operation group, the operation was still smooth. However, compared with on-site group, the percentage of clear view time in the duodenum was significantly shortened in remote group: [(77.8±8.2)% vs. (83.9 ± 6.4)% , P=0.024]. Statistically significant difference was detected in percentage of clear view time neither in other sites, nor was in the total operating time between two groups. The operating time in each part of remote group was obviously longer than that of manual group as followings, pharyngeal (27.3±4.2) s vs. (9.2±1.3)s (P<0.001), esophageal (29.7±6.4)s vs. (19.3±1.6)s (P=0.004), stomach (56.7±17.0)s vs. (40.3±7.0)s (P=0.003), pylorus (20.2±5.5)s vs. (9.3±1.3)s (P<0.001), duodenum (78.2±16.0)s vs. (29.3±5.6)s (P<0.001). Thus the total operating time was also longer in remote group as (559.0±87.2)s vs. (253.1±16.6)s (P<0.001). The respective time in pharynx, esophagus, stomach, pylorus, duodenum, or the overall time was all longer in remote group than that in manual group. Conclusions The soft endoscopy robot YunSRobot has satisfactory safety and stability. Remote upper gastrointestinal endoscopy can be completed based on common network and an endoscope simulation model with smooth operation. The inspection time by YunSRobot robot per part and the overall time are longer than those of manual operation on site, still, remote operating time meets the standard of upper gastrointestinal endoscopy.
RESUMEN
Objective To investigate the effect of capsule endoscopy on the small intestinal mucosa in the state of air insufflation. Methods Patients undergoing capsule endoscopy from November 2011 to April 2012 were divided into the air insufflation intervention group ( n＝14) and routine examination group (n＝13) by random number table method. The detection rate of small bowel disease, the transit time of capsule endoscope in small intestine, the degree of intestinal cleaning and the degree of intestinal lumen expansion were compared between two groups. Results There was no significant difference in total intestinal examination rate [ 85. 71%( 12/14) VS 61. 54%( 8/13),P＝0. 209] or disease detection rate [ 71. 43%(10/14) VS 84. 62%( 11/13), P＞0. 05] between air insufflation intervention group and conventional examination group. The mean procedure time of the air insufflation intervention group was 270. 86 ± 144. 85 min, which was shorter than that of the conventional examination group (325. 15±161. 76 min, P＝0. 369). The overall cleanliness of the air insufflation intervention group was higher than that of the conventional examination group (2. 05±0. 40 VS 1. 75±0. 40,P＝0. 060). The overall degrees of expansion of small intestine lumen were 1. 79 ± 0. 40 and 1. 38 ± 0. 29 scores, respectively ( P ＝ 0. 004 ). Conclusion Capsule endoscopy can significantly improve the degree of intestinal lumen expansion with trend of improving the overall cleanliness of the small intestine, and shortening the working time of the small intestine.

Objective To evaluate the value of perioperative multimodal stratified analgesia guided by PPRS-CYMZ 2.0. Methods One hundred and sixteen patients of both sexes, aged 16-85 yr, of A-merican Society of Anesthesiologists physical statusⅠ-Ⅲ, scheduled for elective surgery in our hospital in August 2016, were included in this study and assigned into empirical analgesia group(group E, n=79) and stratified analgesia group(group S, n=73). The risk of postoperative pain was estimated by an expe-rienced associate chief anesthesiologist based on his clinical experience, and the perioperative analgesic protocol was determined in group E. The risk of postoperative pain was assessed using the perioperative pain risk scale PPRS-CYMZ 2.0 by another experienced associate chief anesthesiologist, the risk was stratified according to the scores, and the corresponding stratified analgesic protocol was determined in group S. Vis-ual analog scale scores and parents′satisfaction with analgesia were recorded on postoperative day 30. The requirement for preventive analgesia, total pressing times of patient-controlled analgesia(PCA)pump in 0-6 h, 6-24 h and 24-72 h periods, PCA background infusion dose and consumption of rescue analgesics were recorded. The development of adverse events during postoperative hospital stay and postoperative re-covery were also recorded. Analgesia-related parameters of medical economics were calculated. Results There was no significant difference in postoperative pain risk stratification between group E and group S(P>0.05), and the majority of patients were at moderate risk. Compared with group E, no significant change was found in visual analog scale scores on postoperative day 30, PCA background infusion dose or incidence of postoperative adverse effects(P>0.05), the requirement for preventive analgesia and satisfaction scores were significantly increased in high risk patients, the consumption of rescue analgesics was decreased in moderate risk patients(P<0.05), no significant change was found in the total pressing times of PCA pump in each time period in low risk patients(P>0.05), the total pressing times of PCA pump was significantly decreased, and the direct analgesic cost per patient and total analgesic cost were decreased in moderate and high risk patients, and the first ambulation time and length of postoperative hospital stay were shortened in high risk patients in group S(P<0.05). Conclusion PPRS-CYMZ 2.0 can achieve perioperative multi-modal stratified analgesia and individualized treatment.

Objective To evaluate the effect of ultrasound-guided arterial catheterization in internships of anesthesiology.Methods Sixty students were randomly divided into ultrasound-guided teaching group(n=30,3 male) and traditional teaching group (n=30,4 male).In the two groups,the ultrasound-guided arterial catheterization technology and artery catheterization technique were adopted respectively for teaching.The success rate of arterial catheterization was compared between the two groups after 2 months internships and when finishing internships of anesthesiology.The questionnaire was investigated in ultrasoundguided teaching group after finished internships of anesthesiology.Results The success rate of arterial catheterization in ultrasound-guided teaching group was extremely higher than in traditional teaching group after 2 months internships of anesthesiology (52 ± 8)％ vs.(38 ± 10)％,(x2=7.746,P=0.005).After finishing internships of anesthesiology,the success rate of arterial catheteri-zation was (67±7)％ in ultrasound-guided teaching group and (59 ± 9)％ in traditional teaching group (x2=5.531,P=0.036).And all students thought ultrasound-guided arterial catheters teaching was helpful to them and could improve their learning interest.Conclusion Ultrasound-guided arterial catheterization is beneficial to the internship teaching of undergraduate of anesthesiology,which can help them to master the arterial catheterization technique better,and improve the success rate of arterial catheterization and their learning interest.
RESUMEN
Objective To investigate esophageal motility characteristics in gastroesophageal reflux disease (GERD) patients with or without dysphagia by high-resolution manometry and 24 h esophageal pH monitoring.Methods From August 2012 to November 2015,GERD patients with symptoms of acid reflux and heart burn who received 24 h esophageal pH monitoring were collected.The differences in esophageal motility were further analyzed between the GERD patients with dysphagia and without dysphagia.Student's t test,x2 test and Fisher's exact test were performed for comparison analysis.Results A total of 194 patients received 24 h esophageal pH monitoring and diagnosed as GERD,and at the same period completed esophageal high-resolution manometry.Among them,there were 17 GERD patients (8.8％) with dysphagia and 177 patients (91.2％) without dysphagia.The main classification of esophageal motility disorder of GERD patients with dysphagia was severe esophageal motility disorders (5/ 17),but the motility type of GERD patients without dysphagia patients mainly was mild esophageal motility disorders (10.2％,18/177).The integrated relaxation pressure,residual pressure of lower esophageal sphincter (LES),and contraction range at 3 cm and 11 cm above LES of GERD patients with dysphagia were all higher than those of patients without dysphagia ((9.70±0.98) mmHg (1 mmHg=0.133 kPa) vs (7.02±0.30) mmHg,(12.75±1.35) mmHg vs (9.18±0.42) mmHg,(106.80± 11.97) mmHg vs (70.82±3.48) mmHg,(82.66±10.70) mmHg vs (56.93±3.11) mmHg),and the differences were statistically significant (t=2.601,2.488,2.887,2.308,all P＜0.05).Distal esophageal contraction integral score of GERD patients with dysphagia was significantly higher than that of GERD patients without dysphagia ((2 128.94±310.47) mmHg · cm · s vs (1 029.88±90.16) mmHg · cm · s),and the difference was statistically significant (t =3.400,P =0.001).However,residual pressure of upper esophageal sphincter was significantly lower than that of patients without dysphagia ((2.84±1.21) mmHg vs (6.18±0.38) mmHg,t=-2.650,P=0.009).Conclusions Esophageal motility disorder of GERD patients with dysphagia is severer than that of patients without dysphagia.High resolution esophageal manometry can provide objective evidence of esophageal dynamics of GERD patients,which can guide the diagnosis and treatment of GERD.
RESUMEN
The formative assessment system has been applied to the internship education for the clinical anesthesia with the aim to improve students' initiative and to evaluate their outcomes more compre-hensively. The students' performance in the shift exchange, case discussion, raising question, solving question at the time points of after the preclinical train, one month and 3 months into the anesthesia internship, and after the completion of internship, and their capability in preoperative patient assessment, condition report, clinical practice, review writing have been evaluated to determine the educational quality and to instruct the improvement of educational approach. Assess process takes into account both the individuality and the gen-eral character of the students and feedbacks the evaluation result to improve the practice teaching The im-plementation of the evaluation can promote students' autonomous learning and comprehensively evaluate students' practice process.
RESUMEN
Objective To evaluate the effect of alveolar recruitment maneuver on the perioperative pulmonary function in the morbidly obese patients undergoing laparoscopic sleeve gastrectomy.Methods Forty morbidly obese patients of both sexes,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,aged 18-64 yr,with body mass index ≥ 40 kg/m2,scheduled for elective laparoscopic sleeve gastrectomy,were randomly divided into either control group (group C) or alveolar recruitment maneuver group (group R) using a random number table,with 20 patients in each group.Patients in group C were treated with volume-or pressure-controlled ventilation after creation of pneumoperitoneum,maintaining the peak inspiratory pressure (Ppeak) ≤ 30 cmH2O and partial pressure of end-tidal CO2 35-40 mmHg.Patients in group R received alveolar recruitment maneuver once every 30 min starting from creation of pneumoperitoneum until the end of surgery.Patients were transfered to post-anesthesia care unit (PACU) with endotracheal tube which was extubated when the unified extubation standard was achieved in PACU.The patients who stayed in PACU for 2 h showing no indications for extubation were transfered to intensive care unit for continuous ventilation support.Immediately after intubation,immediately after creation of pneumoperitoneum,at 30,60 and 90 min of pneumoperitoneum,and at the end of pneumoperitoneum,blood samples were collected from the radial artery for blood gas analysis.Immediately after intubation,immediately after creation of pneumoperitoneum,at 30,60 and 90 min of pneumoperitoneum,at the end of surgery,and immediately before discharge from PACU,Ppeak,plateau pressure (Peat),and dynamic lung compliance were recorded.The time for achieving extubation standard and time for achieving the standard for discharge from PACU were recorded.Patients were followed up until discharge,and the feeding time and duration of hospital stay were recorded.Results Compared with group C,PaO2 and oxygenation index were significantly increased at 90 min of pneumoperitoneum,at the end of surgery,and immediately before discharge from PACU,Ppeak was decreased at 60 and 90 min of pneumoperitoneum and immediately after the end of pneumoperitoneum,Pplat was decreased at 60 and 90 min of pneumoperitoneum,the dynamic lung compliance was increased at 30,60 and 90 min of pneumoperitoneum and immediately after the end of pneumoperitoneum,and the time for achieving extubation standard,time for achieving the standard for discharge from PACU,feeding time,and duration of hospital stay were shortened in group R (P＜0.05 or 0.01).In group C,one patient did not present with indications for extubation and were transfered to intensive care unit for continuous ventilation support.Conclusion Intraoperative alveolar recruitment maneuver can effectively improve the intraoperative pulmonary function and promote the recovery of postoperative pulmonary function in the morbidly obese patients undergoing laparoscopic sleeve gastrectomy.
