Objective:To investigate the effect and the neural mechanisms of Apelin-13 on the behavior changes of posttraumatic stress disorder (PTSD) model mice.Methods:Totally 32 SPF grade male C57BL/6J mice aged 6 weeks were divided into 4 groups randomly ( n=8 in each group): control group, model group, normal saline group and Apelin-13 group.The mice model of PTSD was established by single-prolonged stress (SPS) method. The mice in normal saline group and Apelin-13 group were respectively given lateral ventricular microinjection of 0.9% sodium chloride solution (2 μL) and Apelin-13 (1.5 μg/μL, 2 μL)after PTSD modeling. The behaviors of mice were evaluated by open field test, elevated plus maze test and Morris water maze test.The morphological structure and numerical changes of hippocampal neurons were observed by hematoxylin and eosin (HE) staining.The expression of phosphoinositide 3-kinase(PI3K), phosphorylated-PI3K(p-PI3K), protein kinase B(Akt), phosphorylated-Akt (p-Akt), forkhead box O3a (FoxO3a), phosphorylated-FoxO3a(p-FoxO3a), autophagy-related proteins including microtubule-associated protein 1 light chain 3(LC3) and sequestosome 1(p62) were detected by Western blot. SPSS 26.0 software was used for data analysis.The escape latency data of repeated learning training in Morris water maze was conducted by repetitive measurement ANOVA.The comparison of other data among multiple groups was conducted by one-way ANOVA and further pairwise comparisons were conducted by LSD test and Tamhane test. Result:(1) Open field test results showed statistically significant differences in the central area activity distance and residence time in central area among mice in the four groups ( F=15.37, 9.63, both P<0.05). The central area activity distance ((0.06±0.03) m) and residence time ((2.48±1.02) s) of the mice in model group were lower than those of the control group ((0.19±0.05) m, (15.00±8.91) s)(both P<0.05). And the central area activity distance((0.12±0.04)m)and the residence time((13.56±7.64)s)were higher than those of model group((0.06±0.03)m, (2.48±1.02)s)and normal saline group((0.06±0.02)m, (2.82±1.52)s)(all P<0.05). Elevated plus maze test results showed statistically significant differences in the numbers and time entering open arms among the four groups ( F=10.74, 19.12, both P<0.05). The numbers((4.50±2.51) times) and the time ((26.95±17.48) s) entering the open arm of mice in model group were both lower than those of the control group ((13.75±4.71) times, (103.75±42.43)s) and Apelin-13 group ((10.00±5.18) times, (55.98±19.49) s) (all P<0.05). Morris water maze test results showed that in the 4-day learning and training phase, the time and group interaction of escape latency was not significant among the four groups ( F=1.15, P=0.34), but time main effect and group main effect were significant ( F=131.65, 16.98, both P<0.05). On the 2nd to 4th day, mice in model group showed significantly increased escape latency than mice in control group and Apelin-13 group(both P<0.05). And the numbers crossing original platform and the time in the target quadrant of Apelin-13 group were both higher than those of model group and normal saline group (all P<0.05). (2) HE staining results showed that neurons in the hippocampal CA1 and CA3 area of mice in model group and normal saline group were swollen and arranged loosely.The hippocampal neurons in control group and Apelin-13 group were arranged neatly and densely. (3) Western blot results showed statistically significant differences in the protein expression of p-PI3K, p-Akt, p-FoxO3a, p62 and the ratio of LC3Ⅱ/LC3Ⅰ among the four groups ( F=21.37, 37.35, 20.71, 13.26, 37.65, all P<0.05). The protein expression of p-PI3K, p-Akt, p-FoxO3a and p62 in Apelin-13 group((0.92±0.07), (0.90±0.09), (0.89±0.13), (1.03±0.08)) were higher than those in model group((0.59±0.04), (0.50±0.07), (0.49±0.11), (0.68±0.04)) and normal saline group((0.61±0.06), (0.50±0.08), (0.53±0.11), (0.70±0.05))(all P<0.05), and the ratio of LC3Ⅱ/LC3Ⅰ in Apelin-13 group(0.60±0.06) was lower than those in model group(0.92±0.10) and normal saline group(0.99±0.05) (both P<0.05). Conclusion:Apelin-13 can alleviate the anxiety-like behavior and impaired spatial learning and memory in PTSD model mice. The mechanism may be related to the up-regulation of PI3K/Akt/FoxO3a autophagy pathway.

Objective:To promote the evidence application of the "Expert Consensus on Nursing Care for Prevention of Adult Oral Tracheal Intubation Unplanned Extubation" and verify its effectiveness.Methods:This was a quasi-experimental study. A total of 31 ICU nurses from Tianjin Teda Hospital were trained by workshops, in order to help promote the evidence transformation.

Conclusions:The "Expert Consensus on Nursing Care for Prevention of Adult Oral Tracheal Intubation Unplanned Extubation" can provide guidelines for clinical nursing practice. While preventing unplanned extubation, it can standardize nurses' behavior and promote medical-nursing cooperation.

BACKGROUND: Amygdala plays an important role in the neurobiological basis of panic disorder (PD), and the amygdala contains different subregions, which may play different roles in PD. The aim of the present study was to examine whether there are common or distinct patterns of functional connectivity of the amygdala subregions in PD using resting-state functional magnetic resonance imaging and to explore the relationship between the abnormal spontaneous functional connectivity patterns of the regions of interest (ROIs) and the clinical symptoms of PD patients. METHODS: Fifty-three drug-naïve, non-comorbid PD patients and 70 healthy controls (HCs) were recruited. Seed-based resting-state functional connectivity (rsFC) analyses were conducted using the bilateral amygdalae and its subregions as the ROI seed. Two samples t test was performed for the seed-based Fisher's z -transformed correlation maps. The relationship between the abnormal spontaneous functional connectivity patterns of the ROIs and the clinical symptoms of PD patients was investigated by Pearson correlation analysis. RESULTS: PD patients showed increased rsFC of the bilateral amygdalae and almost all the amygdala subregions with the precuneus/posterior cingulate gyrus compared with the HC group (left amygdala [lAMY]: t  = 4.84, P  <0.001; right amygdala [rAMY]: t  = 4.55, P  <0.001; left centromedial amygdala [lCMA]: t  = 3.87, P  <0.001; right centromedial amygdala [rCMA]: t  = 3.82, P  = 0.002; left laterobasal amygdala [lBLA]: t  = 4.33, P  <0.001; right laterobasal amygdala [rBLA]: t  = 4.97, P  <0.001; left superficial amygdala [lSFA]: t  = 3.26, P  = 0.006). The rsFC of the lBLA with the left angular gyrus/inferior parietal lobule remarkably increased in the PD group ( t  = 3.70, P  = 0.003). And most of the altered rsFCs were located in the default mode network (DMN). A significant positive correlation was observed between the severity of anxiety and the rsFC between the lSFA and the left precuneus in PD patients ( r  = 0.285, P  = 0.039). CONCLUSIONS Our research suggested that the increased rsFC of amygdala subregions with DMN plays an important role in the pathogenesis of PD. Future studies may further explore whether the rsFC of amygdala subregions, especially with the regions in DMN, can be used as a biological marker of PD.

Patients' subjective feelings, that is, patient-reported outcomes, has attracted increasing attention in patients with inflammatory bowel disease (IBD) , which plays an important role in monitoring the progress of patients' disease and guiding clinical decision-making. This article reviews the current status of assessment tools and clinical applications of patient-reported outcomes in IBD patients. This article aims to help medical and nursing staff choose assessment tools suitable for IBD patients in China, standardize the development and localization process of assessment tools, promote the application and development of patient-reported outcomes of IBD patients in China, and optimize disease management of IBD patients.

Inflammatory bowel disease (IBD) is a chronic non-specific intestinal inflammatory disease of unknown etiology, which is characterized by recurrent episodes and prolonged refractory recovery. Financial toxicity refers to the objective economic burden and subjective economic distress caused by medical expenses caused by the disease to patients. IBD patients show a certain level of financial toxicity due to frequent visits to doctors for a long time. This article reviews the concept of financial toxicity, evaluation tools and the current status of financial toxicity in IBD patients, analyzes the influencing factors of financial toxicity in IBD patients from the aspects of general demography factors, disease and treatment and psychosocial aspects, summarizes and puts forward the countermeasures of toxicity of IBD patients to reduce the economic and the direction of the future study, so as to provide reference for related research.

Objective:Scope review of exercise-related research in patients with inflammatory bowel disease (IBD), while pointing out the limitations of existing research, and providing references for future studies in this area.Methods:We searched PubMed, EMBASE, Web of science, Cochrane databases, China Biology Medicine, Chinese National Knowledge Infrastructure, Wan Fang Data, and Chinese Science Journal Database for studies related to exercise intervention in patients with IBD from January 1974 to July 2020. We extracted data from the included studies. Then we summarized and presented the results.Results:16 articles were finally included, of which 14 were randomized controlled trials and 2 were quasi-experimental studies. Results show that exercise methods can be divided into four categories: aerobic exercise, resistance exercise, flexibility exercise and mixed exercise. The intensity of exercise was mostly low to moderate. The frequency of exercise was mostly 3 times/week, lasting for 30-60 minutes per session. The results showed that exercise had positive effects on physical fitness, bone density, anxiety and depression, quality of life among patients with IBD. However, the effect of exercise on disease activity are diverse.Conclusion:exercise is beneficial to the mental and physical health among this group, but the existing studies have small sample sizes, short exercise intervention period, neglect of individualization in exercise prescription design, low exercise compliance, non-uniformity of exercise effect evaluation indicators.

Objective:To explore the influence of hypophosphatemia on weaning from mechanical ventilation.Methods:An observational study was conducted. The medical records of 30 mechanical ventilated patients with hypophosphatemia admitted to intensive care unit of Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2018 to August 2020 were analyzed; another 60 mechanical ventilated patients with normophosphatemia around the same time were enrolled as controls by 1∶2 case-control matching based on gender, age, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, sequential organ failure assessment (SOFA) score. And then the duration of invasive mechanical ventilation, times of spontaneous breathing trial (SBT), the diaphragmatic ultrasonography movement indexes, and outcome of weaning and prognosis during hospitalization were compared between the two groups. Receiver operator characteristic curve (ROC curve) was plotted to calculate the areas under ROC curve (AUC) and cut-off values of serum phosphorus for successful weaning and hospital survival. The correlations between the diaphragmatic ultrasonography movement indexes and serum phosphorus were analyzed by Pearson partial correlation analysis.Results:Compared with normophosphatemic group, the duration of invasive mechanical ventilation in hypophosphatemia group was significantly longer [days: 13.0 (7.0, 22.0) vs. 10.0 (5.5, 14.0), P < 0.05], and SBT attempts were more often [times: 3 (0, 5) vs. 1 (1, 2), P < 0.01], while the rate of successful weaning was lower (53.3% vs. 91.7%, P < 0.01), and the hospital mortality was higher (20.0% vs. 1.7%, P < 0.01). ROC curve analysis showed that serum phosphorus could predict successful weaning of mechanical ventilated patients, the AUC was 0.795, and the optimum cut-off value of serum phosphorus was 0.85 mmol/L with sensitivity of 73.2% and specificity of 84.2%. Serum phosphorus could predict hospital survival of mechanical ventilated patients, the AUC was 0.782, and the optimum cut-off value of serum phosphorus was 0.48 mmol/L with sensitivity of 81.9% and specificity of 85.7%. Compared with normophosphatemic group, diaphragm thickness at the end of inspiration (DTei), diaphragm thickness at the end of expiration (DTee), diaphragm thickening fraction (DTF), diaphragm excursion (DE) in hypophosphatemia group were all significantly decreased [DTei (cm): 0.19±0.07 vs. 0.27±0.08, DTee (cm): 0.14±0.05 vs. 0.19±0.06, DTF: (33.55±16.17)% vs. (45.04±18.66)%, DE (cm): 1.17±0.49 vs. 2.28±0.69, all P < 0.01]. Pearson partial correlation analysis showed that linear correlations were found between serum phosphorus and DTei, DTee, DTF, DE ( r values were 0.442, 0.351, 0.293, 0.628 respectively, all P < 0.01). Conclusions:Serum phosphorus may have correlation with the diaphragmatic ultrasonography movement indexes. Hypophosphatemia may impair the contractile properties of diaphragm, induce more SBT attempts and longer duration of invasive mechanical ventilation, and affect outcome of weaning and prognosis.

Objective:To construct a drug knowledge base based on drug instructions.Methods:Six hundred randomly selected drug instructions were labeled manually and divided into training set and test set. The training was based on bidirectional long short-term memory(Bi-LSTM) and conditional random fields(CRF) model to complete the recognition of medical entities. The extracted entities were standardized by the hybrid model of " similarity calculation and rule mapping table" , and then the drug information was imported into the Access database.Results:In the task of named entity recognition based on Bi-LSTM and CRF model, except for the crowd entities, the other entities had achieved good results with an F-value higher than 85%. Based on the hybrid model of " similarity calculation and rule mapping table" , the accuracy of entity standardization was 88.23%.Conclusions:The effect of the machine learning model in this study is similar to that of other named entity recognition and entity standardization studies, which can complete the task of drug knowledge base construction satisfactorily.
