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.

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.

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.
