ABSTRACT

Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders.Impaired social functioning is a core characteristic of individuals with ASD.Social attention deficits are important manifestation of their impaired social functioning.And it mainly reflected in the gaze on faces and social interactions.Eye movement technology is an objective and sensitive non-invasive measurement tool.Its application makes the measurement of individual core characteristics of ASD more accurate and objective.A review of recent studies revealed that the type of eye-movement stimuli for social attention in patients with AD gradually shifted from face image processing to social interaction scenes, and developed from static presentation to dynamic presentation.Dimensional embodiment of the progress of eye-movement studies of social attention in individuals with ASD.These studies suggest that individuals with ASD are less likely to gaze at the face region and the eye region of the face.More studies are currently using eye-tracking technology, and the analysis of emotional face gaze reveals that, the reduction in eye gaze in individuals with ASD is due to the discomfort associated with threatening faces.These findings validate the " gaze aversion" hypothesis regarding impaired social attention in individuals with ASD.Related neural mechanism studies have found a general lack of attention to social cues in the environment in individuals with ASD.Brain regions such as the amygdala, cingulate gyrus, superior temporal sulcus and anterior insula are associated with social attention in individuals with ASD.Especially with the superior temporal sulcus, the dorsal and ventral sides of the anterior insula, and so on.Future research should explore the cognitive neural mechanisms of social attention deficits in ASD, and the application of advanced information technology, such as eye-tracking technology, in the rehabilitation of patients with ASD.

ABSTRACT

Objective:To investigate the influence of hypomagnesemia on the prognosis of patients with severe sepsis.Methods:A retrospective study was conducted. The clinical data of 207 septic patients admitted to the department of critical care medicine of the First Affiliated Hospital of University of Science and Technology of China from January 1, 2016 to December 21, 2020 were analyzed, including gender, age and laboratory indicators within 24 hours after sepsis diagnosis [procalcitonin (PCT), C-reactive protein (CRP), blood lactic acid (Lac), pH value and blood magnesium, calcium, chlorine and phosphorus levels]. The acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, sequential organ failure assessment (SOFA) score and 28-day prognosis were collected. The patients were divided into survival group and non-survival group according to the prognosis, and the clinical data and laboratory indexes were compared between the two groups. Pearson correlation test was used to analyze the correlation between clinical indicators. Multivariate Logistic regression analysis was used to screen the risk factors affecting the prognosis. The receiver operator characteristic curve (ROC curve) was drawn, and the area under ROC curve (AUC) was calculated to evaluate the potential prognostic indicators.Results:Among the 207 septic patients, 102 survived and 105 died on the 28th day, and the 28-day mortality was 50.72%. There were no significant differences in gender, age, CRP, pH value, blood chlorine or blood phosphorus levels between the two groups. The blood magnesium and blood calcium levels in the non-survival group were significantly lower than those in the survival group [blood magnesium (mmol/L): 0.68±0.14 vs. 0.80±0.12, blood calcium (mmol/L): 1.93±0.21 vs. 2.01±0.20, both P < 0.01], and PCT, Lac, APACHE Ⅱ score and SOFA score were significantly higher than those in the survival group [PCT (mg/L): 8.32 (1.64, 55.01) vs. 3.55 (0.97, 12.31), Lac (mmol/L): 2.90 (1.70, 4.30) vs. 2.10 (1.03, 3.89), APACHE Ⅱ score: 21.24±6.40 vs. 17.42±7.02, SOFA score: 9.14±3.55 vs. 6.91±3.31, all P < 0.01]. Among the 207 patients, 96 patients had normal blood magnesium level (0.75-1.25 mmol/L) and 111 patients had hypomagnesemia (< 0.75 mmol/L). The 28-day mortality of septic patients in the hypomagnesemia group was significantly higher than that in the normal magnesium group [61.26% (68/111) vs. 38.54% (37/96), P < 0.01]. Pearson correlation analysis showed that the blood magnesium level of sepsis patients was negatively correlated with PCT ( r = -0.173, P < 0.05), and it was positively correlated with APACHE Ⅱ score ( r = 0.159, P < 0.05), but it had no correlation with CRP or SOFA score ( r values were -0.029 and 0.091, both P > 0.05). Logistic regression analysis showed that serum magnesium, APACHE Ⅱ score and SOFA score were independent risk factors for 28-day death in patients with sepsis [serum magnesium: odds ratio ( OR) < 0.001, 95% confidence interval (95% CI) was 0.000-0.002, P < 0.001; APACHE Ⅱ score: OR = 1.092, 95% CI was 1.022-1.168, P = 0.010; SOFA score: OR = 1.168, 95% CI was 1.026-1.330, P = 0.019]. ROC curve analysis showed that blood magnesium and APACHE Ⅱ score had a certain predictive value for 28-day mortality in patients with severe sepsis [AUC (95% CI) was 0.723 (0.655-0.791) and 0.680 (0.607-0.754), respectively]. When the blood magnesium threshold was 0.64 mmol/L, the sensitivity was 41.0% and the specificity was 93.1%. When APACHE Ⅱ score threshold was 16.50, the sensitivity was 78.1% and the specificity was 55.9% indicating that the specificity of serum magnesium was higher than that of APACHE Ⅱ score. Conclusions:Severe septic patients complicated with hypomagnesemia have a poor prognosis. Serum magnesium level can be used as a prognostic indicator for severe septic patients.

ABSTRACT

ObjectiveTo establish a neuroinflammation-based obesity and depression comorbidity (COM) model in mice and explore the pharmacodynamics and preliminary pharmacological mechanism of tripterine on COM mice. MethodC57BL/6J mice were randomly divided into a normal group (Chow), a diet-induced obesity group (DIO), and a COM group. The mice in the COM group were fed on a high-fat diet and chronically stressed with moist litter for 12 weeks to establish the COM model. C57BL/6J mice were randomly divided into a Chow group, a COM group, and a tumor necrosis factor-α(TNF-α) knock-down group. In the TNF-α knock-down group, TNF-α shRNA adeno-associated virus was injected into the amygdala through brain stereotaxis, and the expression of TNF-α in the amygdala was down-regulated. C57BL/6J mice were randomly divided into a Chow group, a DIO group, a DIO + low-dose tripterine group (0.5 mg·kg-1), a DIO + high-dose tripterine group (1.0 mg·kg-1), a COM group, a COM + low-dose tripterine group (0.5 mg·kg-1), and a COM + high-dose tripterine group (1.0 mg·kg-1). The body weight, food intake, glucose tolerance, white/brown fat ratio, serum total cholesterol (TC), triglyceride (TG), and high-/low-density lipoprotein cholesterol (HDL-C and LDL-C) content were recorded, and obesity of mice in each group was evaluated. Forced swimming test (FST), tail suspension test (TST), and open field test were used to evaluate the degree of depression of mice in each group. Immunofluorescence staining was used to detect the protein expression levels of neuropeptide Y, tryptophan hydroxylase 2 (TPH2), and brain-derived neurotrophic factor (BDNF) in various brain nuclei of mice. Correlation analysis was used to detect the correlation of obesity and depression indexes. ResultThe comparison of the Chow group and the DIO group indicated that COM mice showed obesity and depression. To be specific, obesity was manifested as increased body weight and food intake (P<0.05, P<0.01), as well as increased NPY expression in the central amygdala, and depression was manifested as prolonged immobility time in FST and TST (P<0.01), and reduced TPH2-positive 5-hydroxytryptamine neurons in the dorsal raphe nucleus (DRN) and basolateral nucleus of the amygdala (BLA). The down-regulation of TNF-α protein in BLA of COM mice shortened the immobility time in FST and TST (P<0.05, P<0.01), increased TPH2/BDNF-positive neurons in BLA, and showed no significant changes in obesity. In DIO mice, the administration of 0.5 mg·kg-1 tripterine for 9 days significantly decreased the 60 min blood glucose in glucose tolerance (P<0.01) and food intake (P<0.05). In COM mice, 1.0 mg·kg-1 tripterine was administered for 14 days to significantly decrease 30 min blood glucose in glucose tolerance (P<0.01), and food intake (P<0.05), and immobility time in TST (P<0.01), increase TPH2-BDNF double-labeled cells in BLA and DRN, and reduce the area of TMEM119-stained cells. ConclusionThe model of obesity and depression comorbidity can be properly induced in mice under the condition of dual stress of energy environment. Tripterine can effectively interfere with obesity-depression comorbidity, and its mechanism may be related to the inhibition of central nervous system inflammation.

ABSTRACT

ObjectiveTo observe the intervention effect of Ruyi Zhenbao pills (RYZBP) on central pain after thalamic stroke in mice and explore the underlying mechanism. MethodThe central post-stroke pain syndrome (CPSP) model was induced by stereotactic injection of type Ⅳ collagenase into the hypothalamus in mice. The mice were divided into a sham group, a model group, low-, medium-, and high-dose RYZBP groups (0.65, 1.3, 2.6 g·kg-1), and a pregabalin group (0.075 g·kg-1). Seven days after modeling, the mice in the groups with drug intervention were administered with corresponding drugs by gavage according to the body mass, once per day for 25 days, while those in the sham group and the model group received an equal volume of normal saline. During this period, mechanical pain and cold pain were detected at different time points, and the apoptotic state of brain tissue cells was detected by in situ terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL). The 36 classical broad-spectrum inflammatory factors were quantitatively analyzed by liquid-phase chip technology, and differential molecules were screened out and verified by Western blot and enzyme-linked immunosorbent assay (ELISA). ResultCompared with sham operation group, mechanical pain threshold and cold sensitive pain threshold in model group were significantly changed (P<0.01). TUNEL results showed that apoptosis of brain cells was obvious. Western blot and ELISA results showed that the expressions of interleukin-1α (IL-1α) and chemokine ligand 5 (CCL5) increased in hypothalamus tissue and serum, while the expressions of Ang-2, granulocyte-colony-stimulating factor (G-CSF) and IL-4 decreased significantly (P<0.01). Compared with model group, RYZBW dose groups significantly increased mechanical pain threshold, decreased cold sensitivity pain threshold, decreased hypothalamus cell apoptosis ratio (P<0.01), decreased the expression of IL-1α and CCL5 in hypothalamus tissue and serum, while the expression of ANG-2, G-CSF and IL-4 were significantly increased (P<0.05). ConclusionRYZBP can relieve hyperalgesia in CPSP mice, and its mechanism is related to the regulation of the expression of pro-/anti-inflammatory factors IL-1α, CCL5, IL-4, G-CSF, and Ang-2.

ABSTRACT

Objective:To investigate the effect of computer-assisted cognitive remediation therapy (CACR) on the improvement of cognitive functioning in patients with major depressive disorder during the recovery period.Methods:Sixty-seven patients with major depressive disorder, during the recovery period, were included according to the inclusion criteria. All of them were from Hangzhou Seventh People’s psychiatry department and were selected during the September 2016 to September 2018 time period and were randomized into the CACR group and the observation group. The previously used conventional drug treatment was continued for 8 weeks in both groups, but an additional 8-weeks was given to the CACR group, mainly for intensive attention training and memory. The CACR training time was 8 weeks, once a day each for attention and memory training for 20 minutes. Before treatment and at the end of the 8-week treatment, the Wisconsin Card Sorting Test (WCST), Trail Making Test A, Trail Making Test B, and Stroop test were used to measure cognitive function.Results:67 patients with depression during the remission period were included. The control group included 32 patients, 18 males (57%) and 14 females (43%), aged (29.0±9.2) years old; 35 patients in the intervention group, 20 males (56%) and 15 females (44%), aged (28.0±9.2) years old. There were no significant differences between the two groups in terms of gender, age, years of education, scores on the Chinese version of Webster's adult intelligence scale, scores on Hamilton depression scale, and course of illness. There were no significant differences between the groups in terms of WCST performance, TMT performance, and scores on the Stroop test at baseline ( P>0.05). After the 8-week treatment, the CACR group demonstrated better performance on the mean number of trials [(76.8±14.3) vs.(83.6±14.6)], the number of correct classifications [(27.9±1.8) vs.(26.6±2.6)], perseverative errors [(24.4±3.3) vs.(27.4±4.8)],non-perseverative errors [(17.97±3.1) vs.(22.2±4.3)], and the mean time for completing part B of TMT [(86.1±15.6) vs.(119.6±16.2)]. However, there were no significant differences between the groups on mean number of categories completed, mean time for completing part A of TMT, the right numbers in Stroop-C and Stroop-CW, and the completed numbers in Stroop-C and Stroop-CW ( P>0.05). Conclusion:CACR can effectively improve the cognitive function in patients with major depressive disorder who have stabilized.

ABSTRACT

Obsessive-compulsive disorder (OCD) is a kind of conrmon clinical mental disorder.It has a prolonged course of disease and is difficult to cure.The treatment methods of obsessive-compulsive disorder are mainly composed of drug therapy and psychotherapy, but some patients have poor response to drug therapy.Transcranial magnetic stimulation (TMS) is a non-invasive nerve stimulation technique and is widely used in neuropsychiatric diseases.Transcranial magnetic stimulation is gradually increasing in the treatment of obsessive-compulsive disorder.To date, researches at home and abroad have reported that transcranial magnetic stimulation can improve the symptoms of obsessive-compulsive disorder and help to improve its cognitive function.However, the clinical therapeutic effects reported are inconsistent due to different stimulation sites, stimulation parameters, sample size and stimulation time.Especially in recent years, transcranial magnetic stimulation research on obsessive-compulsive disorder has made further exploration in target selection, stimulation sequence, stimulation mode and so on.This paper focuses on the clinical effects of different stimulation sites on the treatment of OCD, and provids new ideas for further intervention and treatment of OCD.

ABSTRACT

Objective@#Attentional biases toward emotional scenes may represent vulnerability and maintenance factors in depression. Antidepressant therapy may improve cognitive function and reduce depression, and is considered as the mechanism of action of antidepressants. Therefore, we conducted an eye-tracking test to examine whether selective serotonin re-uptake inhibitor (SSRI) antidepressants can reduce negative attentional biases and elicit clinical responses in depression. @*Methods@#Twenty first-episode depressive patients freely viewed three types of pictures that depicted different emotional scenes (i.e., positive-control, neutral-control, and negative-control) for 4,000 ms while their eye movements were monitored. The attentional bias to different emotional scenes was assessed before and after eight weeks of SSRI treatment using the eye-tracking method. The control group included a group of healthy individuals. @*Results@#The results revealed that first-episode depressive patients oriented their gaze more frequently to negative images and less to happy images, compared to controls. Importantly, the attentional bias in depressive patients was regulated after eight weeks of SSRI treatment. Patients showed an increased tendency to fixate on positive images and a decreased tendency to focus on negative images. @*Conclusion@#This suggests that SSRI antidepressants decrease vulnerability to negative images, while having an effect on attention in respect to positive images.

ABSTRACT

Objective@#To evaluate the in vitro activity of ceftazidime-avibactam (CAZ-AVI) alone or in combination with colistin (COL) against clinically isolated extensively drug-resistant Pseudomonas aeruginosa (XDR-PA).@*Methods@#Minimum inhibitory concentration (MIC) of 16 clinical XDR-PA isolates was determined by broth dilution method and chessboard design when CAZ-AVI and COL were used alone or in combination, then the combined inhibitory concentration index (FICI) was calculated. Class A [Klebsiella pneumoniae carbapenemase β-lactamase (blaKPC), Guiana extended-spectrum β-lactamase (blaGES)], Class B [imipenemase β-lactamase (blaIMP), Verona-Integronmetallo β-lactamase (blaVIM), New Delhi metallo β-lactamase (blaNDM), German imipenemase β-lactamase (blaGIM), Sao Paulo metallo -β- lactamase (blaSPM)], Class C [AmpC β-lactamase (blaAmpC)], Class D [oxacillinase β-lactamase (blaOXA)] β- lactamase-related resistance genes were detected by polymerase chain reaction. Drug-resistant mutation frequencies of each strain were determined on a drug-containing plate. The time kill curves of three XDR-PA were plotted by colony counting method. A biofilm model was established in vitro, and the synergistic effect of CAZ-AVI and COL on biofilm inhibition was detected by methythiazolyl tetrazolium assay (MTT).@*Results@#The MICs of 16 XDR-PA for CAZ-AVI ranged from 1 mg/L to 128 mg/L, and three of the isolates showed resistance (MIC > 8 mg/L). The FICI range of CAZ-AVI combined with COL was 0.312-1.000. Four isolates were synergistic, while the other 12 isolates were additive. Three isolates resistant to CAZ-AVI contained Class B resistance genes such as blaIMP and blaVIM, while 13 susceptible isolates carried resistance genes belonging to Class A, C or D. The logarithm values of mutation frequencies of drug resistance in CAZ-AVI group, COL group and combination group were -4.81±0.88, -7.06±0.69 and -9.70 (-9.78, -9.53), respectively. There were significant differences among the three groups (H = 33.601, P < 0.001), and between every two groups (adjusted P < 0.05). In time kill curves, the phytoplankton load of three XDR-PA decreased more than 6 log CFU/L when these two drugs were used together, and number of PA1819 planktonic bacteria decreased more than 5.1 log CFU/L compared with monotherapy group. Viable quantity in biofilm (A490) of normal saline group, CAZ-AVI group, COL group and CAZ-AVI-COL group were 0.665±0.068, 0.540±0.072, 0.494±0.642 and 0.317±0.080, respectively. There was significant difference between the other two groups (all P < 0.001), except for that between CAZ-AVI group and COL group (P = 0.109).@*Conclusions@#CAZ-AVI combined with COL can effectively improve the bactericidal effect of each drug alone on XDR-PA. The regimen can also reduce the production of drug-resistant bacteria and inhibit the formation of biofilm. Therefore, it is a potential treatment for XDR-PA infection.

ABSTRACT

Objective To investigate the expression of circular RNA (circRNA) in peripheral blood of gravidas with gestational diabetes mellitus (GDM) using gene chip technology, and to provide evidence for studying pathogenesis of GDM. Methods A prospective cohort-based nested case-control study was used to select 1 018 pregnant women who were examined and delivered in Guangzhou Women and Children's Medical Center from September 2014 to April 2016. The information of prenatal examination was recorded and the outcome of delivery was followed up. Six pregnant women diagnosed as GDM were selected as the GDM group. Six normal pregnant women who were collected blood samples by 1 ∶ 1 were selected as the control group. The difference of gestational week was less than 7 days, the number of previous pregnancies was less than 2 times, and the difference of previous delivery times as same as the control group. The expression of circRNA in maternal peripheral blood was analyzed by chromosome microarray technique, and the function and the regulation network forecast were analyzed by GO (http://www.geneontology.org/), KEGG PATHWAY (http://www.genome.jp/kegg/pathway.html) and CircNet(http://circnet.mbc.nctu.edu.tw/). t-test was used for data analysis. ResuLts Compared to the normal pregnant women, 2 678 circRNAs were identified to be differentially expressed >2.0 times in GDM women, among which 1 532 were up-regulated and 1 146 were down-regulated. Functional analysis showed that the up-regulated circRNA was enriched in the biological processes of insulin response, gene silencing regulation, glucagon response and cell senescence. Signal pathway analysis showed that circRNA involved in insulin pathway. Taking has_circ_0042852 and has_circ_0004001 as center, the possible GDM-related regulatory networks were predicted. ConcLusions The peripheral blood of GDM women is rich in circRNAs, which might involve in many biological processes, insulin signaling pathway and possibly induding GDM-related regulatory networks.

ABSTRACT

Objective To explore the role of impulsivity in manic episodes of bipolar I disorder and cognitive impairment. Methods Sixty-one patients with bipolar I manic-episode ( study group) and 43 healthy volunteers (control group) were included in the study,and the cognitive function and impulsivity of the subjects were assessed using the MATRICS consensus cognitive battery (MCCB) and BIS-11 impulsivity scale (BIS-11). The differences in impulsivity and cognitive function between the study group and control group were compared. Partial correlation analysis was used to analyze the correlation between impulsivity and cognitive function in patients with bipolar I manic episode. Results ( 1) The scores of several cognitive function in study group,were significantly lower than those in healthy control group including information pro-cessing speed,attention alertness,word learning,visual learning,working memory,reasoning and problem sol-ving (all P<0. 01). (2)The total score,motor factor score and cognitive factor score of BIS-11 impulse scale in study group were significantly higher than those in control group (58. 39±15. 77 vs 48. 02±11. 16,62. 09± 19. 01 vs 44. 24±21. 09,56. 97±16. 57 vs 50. 06±13. 87,all P<0. 05). Increased overall scores on the bis-11 impulse inventory may be a risk factor for bipolar I episodes( OR=1. 204,95% CI=1. 032-1. 404). (3) In study group,the total score of BIS-11 was negatively correlated with the speed of information processing, working memory,word learning,reasoning and problem solving,and the total score of MCCB(r=-0. 417,-0. 360,-0. 294,-0. 348,-0. 348,P<0. 05). The score of unplanned factor was negatively correlated with the speed of information processing,word learning,the total score of MCCB(r=-0. 397,-0. 302,-0. 358,P<0. 05). The score of cognitive factor was negatively correlated with the speed of information processing,work-ing memory,word learning,reasoning and problem solving,and the total score of MCCB(r=-0. 327,-0. 351,-0. 374,-0. 391,-0. 463,P<0. 05). The score of motor factor was negatively correlated with working memo-ry and the total score of MCCB(r=0. 370,r=0. 389,P<0. 05). Conclusion High impulsivity is a risk factor for manic episodes of bipolar I disorder and may be associated with cognitive impairment in patients with ma-nic episodes of bipolar I disorder.

ABSTRACT

Objective To investigate the effect of early rehabilitation physiotherapy on muscle quality and function in critical patients. Methods A prospective randomized controlled study was performed. Adult critically ill patients admitted to intensive care unit (ICU) of Anhui Provincial Hospital from October 1st, 2016 to August 31st, 2017 who had been hospitalized for more than 7 days and had acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ ) > 8 were enrolled, and they were divided into treatment group and control group according to random number table method. All patients were given routine treatment, and on this basis, the treatment group was given rehabilitation therapy within 24 hours after admission, including limb active / passive activities, respiratory muscle function training and transcutaneous electrical nerve stimulation, etc. Bedside ultrasound was used to measure the area and cross sectional thickness of left rectus femoris muscle and the cross sectional thickness of middle thigh muscle of patients at 1, 4 and 7 days after treatment; at the same time, the muscle strength of sober patients was evaluated by medical research council (MRC) muscle strength evaluation method, and the mechanical ventilation time, ICU hospitalization time and ICU expenses were recorded. Results Forty patients were enrolled in this study, with 20 in each group. Compared with the control group, the difference of left rectus femoris muscle area between 1 day and 4 days, 4 days and 7 days, 1 day and 7 days (cm2: 0.19±0.02 vs. 0.31±0.19, 0.02±0.01 vs. 0.08±0.05, 0.04±0.02 vs. 0.38±0.23), and the difference in left rectus femoris thickness (cm: 0.01±0.01 vs. 0.14±0.13, 0.03±0.03 vs. 0.16±0.14) and the difference in middle thigh muscle thickness (cm: 0.02±0.02 vs. 0.11±0.09, 0.03±0.02 vs. 0.16±0.12) between 1 day and 4 days, 1 day and 7 days in the treatment group were significantly reduced (all P <0.01). The MRC strength score in the treatment group was significantly higher than that of the control group at 7 days (52.06±3.52 vs. 47.94±3.96, P < 0.05). The mechanical ventilation time in the treatment group (n = 15) and the control group (n = 13) were (138.5±34.5) hours and (185.0±40.9) hours, respectively, and the difference between two groups were statistical significance (P < 0.05). Compared with the control group, the incidence rate of ICU acquired muscle weakness (ICUAW) in the treatment group was significantly decreased [5.0% (1/20) vs. 40.0% (8/20), P < 0.05], the length of ICU stay was significantly shortened (days: 17.67±4.91 vs. 22.06±5.94, P < 0.05), and the ICU expenses were significantly reduced (ten thousand yuan: 7.53±2.09 vs. 9.55±1.73, P < 0.05). Conclusion Early rehabilitation physiotherapy can improve the muscle quality and function in critical patients, and decrease the length of ICU stay.

ABSTRACT

Objective To observe the effects of Wutou decoction(WTD)on Anxiety and Depression induced by the L5 spinal nerve ligation (SNL) mice. Methods The ICR male mice were randomly divided into sham,SNL,high-dose,medium-dose and low-dose group of Wutou decoction,and Pregabalin group,with 24 in each group. Except the sham group, SNL models were prepared in the remaining groups of mice. After successful modeling, the high, medium, and low dosages were administered with 12.60, 6.30, 3.15 g/kg of Wutou decoction,and pregabalin group was administered with 0.25 g/kg of pregabalin,and the sham group and the model group was given an equal volume of normal saline. All the administration was once per day, continuously last for 21 days. On the 7/14/21thdays after the operation, the depressive and eanxiety behavior were evaluated by the tests of the sugar water consumption, the open field and forced swimming detection. In addition, the number of the positive cells expressing the extracellular signal-regulated kinase (p-ERK) in hippocampus were analyzed on Day 7/14/21 in each group by Immunohistochemistry and the expression of both p-ERK and postsynaptic density protein 95 (PSD95) in the hippocampus were analyzed on Day 21 by Western blot. Results At 7, 14, and 21thday after administration, compared with the model group, the paw withdrawal mechanical threshold of mice(0.76 ± 0.21 vs.0.05 ± 0.03),(0.93 ± 0.33 vs.0.05 ± 0.01),(1.12 ± 0.20 vs.0.04 ± 0.01)in the high dose group of Wutou decoction respectively increased(P<0.01),and sugar consumption(1.86 ± 0.44 g vs. 0.84± 0.23 g), (1.84 ± 0.10 g vs. 1.02 ± 0.18 g), (1.63 ± 0.31 g vs. 0.75 ± 0.23 g) significantly increased(P<0.01),and immobility time 4 min after swimming(128.90 ± 35.27 s vs.180.30 ± 21.81 s),(125.50 ± 23.07 s vs.195.30 ± 27.70 s),(169.50 ± 23.07 s vs.207.50 ± 7.46 s)significantly decreased(P<0.01),and the retention time in the central area of the open field(35.35 ± 7.61 s vs.13.90 ± 2.27 s),(26.26 ± 3.61 s vs.13.08 ± 1.98 s),(24.04 ± 6.57 s vs.10.62 ± 3.38 s)significantly increased(P<0.01).After 21 days,the number of p-ERK positive cells in the high-dose group of Wutou decoction(11.00 ± 4.89 vs.33.67 ± 7.35)was siginificantly lower than that of the model group,and the hippocampus p-ERK protein(0.15 ± 0.09 vs.0.54 ± 0.04)siginificantly decreased,and the expression of PSD95 protein(0.32 ± 0.04 vs.0.57 ± 0.09)siginificantly decreased(P<0.01). Conclusions The Wutou decoction achieved significant anti-depressant and anti-anxiety effects,and regulated p-ERK expression levels of hippocampus in the late stage of NP.
