The difference of gray matter volume and its correlation with clinical characteristics in patients with anxious depression / 中华行为医学与脑科学杂志

Objective:To explore the difference of gray matter volume between anxious depression(AD)and non anxious depression(NAD) patients, and its correlation with clinical characteristics.Methods:One hundred and fifty patients with depression were included from September 2014 to October 2018, meanwhile 62 healthy controls with matching demographic characteristic were recruited. The severity of the patients was assessed by Hamilton depression scale-17(HAMD-17). Patients were divided into anxious depression group(AD group, n=80)and non-anxious depression group (NAD group, n=70) according to whether anxiety/somatization factor scored 7. All subjects were scanned with 3.0 T underwent structural MRI scan. The structural magnetic resonance data were preprocessed by voxel-based morphometry (VBM). The rest toolkit was used to calculate the difference of gray matter volume among the three groups. By SPSS 19.0, post-hoc t test was used for pairwise comparison and Pearson correlation analysis was performed between gray matter volume and clinical factors in patients with anxious depression. Results:Compared to the NAD group, the gray matter volume of the right middle frontal gyrus(MNI: x=28.5, y=21.0, z=48.0, t=-4.83, Bonferroni multiple comparison adjustment, P<0.05/3) and left dorsolateral superior frontal gyrus(MNI: x=-18.0, y=27.0, z=43.5, t=-6.08, Bonferroni multiple comparison correction, P<0.05/3)were significantly decreased in AD group. Correlation analysis found that the gray matter volume of the right middle frontal gyrus in patients with anxious depression was negatively correlated with the insight of anxiety/somatization factor score ( r=-0.36, P=0.001). Conclusion:The volume of prefrontal lobe in patients with anxiety depression is lower than that in patients with non anxiety depression, which may be related to the serious clinical symptoms in patients with anxiety depression.The decrease of right middle frontal gyrus volume can be used as a potential biological marker for the severity of impaired insight.

Effect of Baihe Dihuang Decoction on synaptic plasticity of hippocampus in rats with anxious depression / 中国中药杂志

To explore the effect of Baihe Dihuang Decoction on the synaptic plasticity of hippocampal neurons in rats with anxious depression. Fifty SD rats were randomly divided into normal group, model group, venlafaxine group(6.75 mg·kg~(-1)), high-dose Baihe Dihuang Decoction group(8.64 g·kg~(-1)) and low-dose Baihe Dihuang Decoction group(4.32 g·kg~(-1)). Chronic restraint stress(6 h) combined with corticosterone(ih, 30 mg·kg~(-1)) was used to establish an anxious depression model, and 7 days after modeling, the administration started and continued for 21 days. The anxiety and depression-like behaviors of the rats were evaluated. Golgi-Cox staining and electron microscopy were used to observe the morphology and ultrastructural changes of synaptic dendrites. Immunofluorescence was used to detect the expression of hippocampal synaptic plasticity protein synapsin-1 and postsynaptic density protein 95(PSD-95). Western blot method was used to detect the expression of functional protein synaptophysin(SYP) and synaptic Ras GTPase activating protein(SynGap). The results showed that the rats in the model group had obvious anxiety and depression-like behaviors, the hip-pocampal dendritic spine density and branch length were reduced, the number of synapses was cut, and the internal structure was da-maged. The average fluorescence intensity of synapsin-1 and PSD-95 was significantly reduced and the expression of SYP and SynGap also decreased. High-dose Baihe Dihuang Decoction could significantly improve the anxiety and depression-like behaviors of model rats, relieve synaptic damage, and increase the expression of synapsin-1, PSD-95, SYP, and SynGap proteins. Therefore, we believe that Baihe Dihuang Decoction can improve anxiety and depression behaviors by regulating the synaptic plasticity of hippocampal neurons.

Objective: To investigate the effects of spina date seed (SDS) and albizzia julibrissin flower (AJF) water extracts on the hypothalamic-pituitary-adrenal (HPA) axis and inflammatory factors IF) in the anxiety depression model rats. Methods: A total of 80 Wistar rats were randomly divided into blank group (n= 10), model group (n=10), low dose of SDS group (n=10), high dose of SDS group (n=10), low dose of AJF group (n=10), high dose of AJF group (n= 10), low dose of SDS-AJF group (n= 10), and high dose of SDS-AJF group (n=10). The rat models of anxiety depression were induced by chronic restraint stress, solitary cage and corticosterone (CORT) subcutaneous injection. The forced swimming test (FST) was used to observe the immobility time of forced swimming of the rats in various groups; Elevated plus maze test (EPM) was used to observe the open arm entry (OE), close arm entry (CE), open arm entry time (OT), and close arm entry time (CT) of the rats in various groups. The total entry of open arms and close arms (TE), OE% and OT% were calculated. ELISA method was used to detect the levels of serum corticotropin releasing hormone (CRH), adrenocorticotropic hormone (ACTH), CORT, inflammatory factors interleukin-lfi (IL-fi) and interleukin-6 (IL-6) of the rats in various groups. HE staining was used to observe the morphology of hippocampal neurons of the rats in various groups. Results: Compared with model group, the immoblity time of forced swimming of the rats in low dose of SDS-AJF group, high dose of SDS-AJF group, high dose of SDS group and high dose of AJF group was decreased (P<0. 05 or P<0. 01); compared with low dose of SDS group and low dose of AJF group, the immoblity time of forced swimming of the rats in low dose of SDS-AJF group was shortened (P<0. 05 or P< 0.01); compared with high dose of SDS group and high dose of AJF group, the immobility time of forced swimming of the rats in high dose of SDS-AJF group was shortened (P<0. 05 or P<0. 01). Compared with model group, the OE% and OT% of the rats in low dose of SDS-AJF group, high dose of SDS-AJF group, high dose of SDS group and high dose of AJF group were increased (P<0. 05 or P<0. 01); compared with low dose of SDS group and low dose of AJF group, the OE% and OT% of the rats in low dose of SDS-AJF group were increased (P<0. 05 or P<0. 01); compared with high dose of SDS group and high dose of AJF group, the OE% and OT% of the rats in high dose of SDS-AJF group were increased (P<0. 05 or P<0. 01). Compared with model group, the levels of serum CRH, ACTH, CORT, IL-1β, and IL-6 of the rats in low dose of SDS-AJF group, high dose of SDS-AJF group, high dose of SDS group and high dose of AJF group were decreased (P<0. 05 or P<0. 01); compared with low dose of SDS group and low dose of AJF group, the levels of serum CRH, ACTH, CORT, IL-1β and IL-6 of the rats in low dose of SDS-AJF group was decreased (P<0. 05 or P<0. 01); compared with high dose of SDS group and high dose of AJF group, the levels of serum CRH, ACTH, CORT, IL-1β, and IL-6 of the rats in high dose of SDS-AJF group was decreased (P<0. 05 or P<0. 01). The HE staining results showed that the hippocampal neurons of the rats in model group were loosely arranged, and a large number of nerve cells were degenerated and the cell layer was reduced. The degeneration of hippocampal neurons of the rats in low and high doses of SDS-AJF groups were significantly relieved, and the nerve cells were arranged closely and the cell layer was clear. Conclusion: Combination of SDS and AJF can improve the behavior of the rats with anxiety depression, protect the hippocampal neurons of rats, reduce the inflammatory response, and adjust the disorder of HPA axis.

Objective To explore the relationship between anxious depression and cortisol rhythm disorder and influencing factors of immune metabolism. And to look for biological markers that can be used for clinical diagnosis and treatment of anxious depression. Methods Totally 43 patients with anxious depres-sion(A-MDD group) and 44 patients with non-anxious depression matched by sex,age and years of education (NA-MDD group)were recruited. Electrochemiluminescence was used to detect the plasma levels of adreno-corticotropic hormone(ACTH),cortisol(COR),c-reactive protein(CRP) and IL-6. Automatic biochemical a-nalysis was used to detect plasma total TC,TG,HDL and LDL. Using logistic regression analysis to discuss the influencing factors of anxiety depression. Results The comparison between the two group showed that the age of first onset,BMI and SBP in the A-MDD group((35. 15±11. 56),(24. 11±3. 03)kg/m2,(130. 09 ±13. 33)mmHg) were significantly higher than those in the NA-MDD group((31. 34± 14. 08),( 22. 70± 3. 19)kg/m2,( 121. 89±12. 49)mmHg)(t=2. 631,2. 009,2. 964,all P<0. 05). The HAMD score and the factor scores of cognitive impairment,change of day and night,delay,sleep disorder and feeling of despair in the A-MDD group((31. 81±5. 39),(8. 03±3. 00),(1. 17±0. 70),(6. 88±1. 93),(4. 44±1. 44),(4. 67± 2. 37)) were significantly higher than those in the NA-MDD group((25. 25±5. 017),(3. 87±3. 12),(0. 79 ±0. 78),(4. 64±2. 22),(3. 34±1. 54),(3. 61±2. 02))(t=2. 297,6. 524,2. 505,5. 210,3. 452,2. 421,all P<0. 05). The plasma TG,CRP and IL-6 levels in the A-MDD group((1. 63±1. 11)mmol/L,(1. 20±0. 77) mg/L,(3. 54±1. 90) pg/L) were significantly higher than those in the NA-MDD group (( 1. 19 ± 0. 66) mmol/L,(0. 933±0. 89)mg/L,(2. 65±1. 34)pg/L) (t=2. 254,2. 250,2. 352,all P<0. 05). The incidence of cortisol disturbance was 72% in the A-MDD group,and 48% in the NA-MDD group,and the difference was statistically significant (χ2=5. 369 P=0. 020). Multivariate Logistic regression found that sleep disorder (β=0. 729,OR=2. 072,95%CI=1. 018-3. 119),IL-6(β=0. 583,OR=1. 792,95%CI=1. 168-2. 748),cog-nitive impairment (β=0. 099,OR=1. 104,95% CI=1. 022-1. 193),cortisol rhythm disorders(β=0. 075, OR=1. 078,95%CI=1. 014-1. 146) were the risk factors for anxious depression. Conclusion Anxious de-pression has a high incidence of cortisol rhythm disorder. The COR and IL-6 may be mediators of cortisol rhythm disorder. IL-6 and cortisol rhythm disorder together with sleep disorder and negative cognition consti-tute maybe high risk factors for anxious depression.

Changes of content of monoamine neurotransmitters and expression of neurotrophic factors in brain regions of rat models of anxious depression / 中国实验动物学报

Objective To study the content of monoamine neurotransmitters and neurotrophic factor in the hippocampus, amygdala and prefrontal cortex in anxious depression rats, and explore the possible pathogenesis.Methods 60 SD rats were randomly divided into normal group, vehicle group, anxiety group, depression group, and anxious depression group, 12 rats in each group.Chronic restraint stress combined with corticosterone injection was used to establish anxiety and depression model, the modeling time was 21 d.After modeling, elevated plus maze test, open field test, and forced swimming test were used to evaluate the anxiety and depression-like behavior, HPLC-ECD was used to detect the content of 5-HT, NE, and DA in the hippocampus, amygdala, and prefrontal cortex of rats.Western-blotting was used to detect the expression of BDNF and NT-3 in rats.Results Rats in anxious depression model group were comparable to the anxiety group in time and frequency entering open arm time, and number of locomotor activity in open field, and it had a significant difference when compared with the control and depression groups (P<0.01 or P<0.05).Immobile time in anxious depression model rats was increased significantly when compared with the control and anxiety groups (P<0.01).Meanwhile, compared with the control group, 5-HT in hippocampus and 5-HT, NE in amygdala or prefrontal cortex were significantly decreased in the depressive rats with anxiety (P<0.01 or P<0.05).Moreover, the content of BDNF and NT-3 was significantly decreased in each brain regions compared with the control group (P<0.01 or P<0.05), and BDNF levels were obviously decreased compared with the anxiety group (P<0.05).Conclusions Rats of anxious depression have significant anxiety and depression-like behaviors.Its mechanism may be associated with the down-regulation of monoamine neurotransmitters and neurotrophic factors BDNF and NT-3 in hippocampus, amygdala, and prefrontal cortex region.

Reduced Venous Blood Basophil Count and Anxious Depression in Patients with Major Depressive Disorder

OBJECTIVE: Anxious depression has a distinct neurobiology, clinical course and treatment response from non-anxious depression. Role of inflammation in anxious depression has not been examined. As an exploratory study to characterize the role of inflammation on a development of anxious depression, we aimed to determine the relationship between white blood cell (WBC) subset counts and anxiety in individuals with major depressive disorder (MDD). METHODS: A total of 709 patients who were newly diagnosed with MDD were recruited. Anxiety levels of participants were evaluated using the Anxiety/ Somatization subitem of the Hamilton Depression Rating Scale. The association between WBC subset fraction and anxiety was evaluated. RESULTS: Basophil and eosinophil sub-fractions showed significant negative correlations with HAM-D anxiety/somatization factor scores (basophils: r=-0.092, p=0.014 and eosinophils: r=-0.075, p=0.046). When an anxiety score (a sum of somatic and psychic anxiety) was entered as a dependent variable, only basophils showed significant negative association with the anxiety scores after adjusting for all other WBC subset counts and demographic factors (t=-2.57, p=0.010). CONCLUSION: This study showed that anxious depression had a decreased basophil subfraction, which might be associated with involvement of inflammation in development of anxious depression.
