Aim To observe the rapid antidepressant effect of Yuejuganmaidazao Decoction on postpatum de-pression offspring , and analyze its influence on the Akt and mTOR expression .Methods After postpartum de-pression model was established , the offsprings were randomly divided into the following groups: control group(CTL-F1,n =8), vehicle group (Veh,n =8) and YG group ( YG, n =8 ) .Veh group was treated with vehicle , YG group was treated with Yueju gan-maidazao Decoction(8.3 g· kg -1 ).Forced swimming test(FST) was measured 24 hours after single adminis-tration.The phosphorylation and total level of Akt and m-TOR in the hippocampus was detected by Western blot.Results The immobility time in YG group was significantly shorter than that in Veh group ( P <0.01 ) , and the expression of p-Akt and p-mTOR in the hippocampus was significantly increased ( P <0.05 ) .Conclusion Yuejuganmaidazao Decoction may rapidly alleviate depression-like behaviors of PPD offsprings through upregulation of Akt and mTOR ex-pression .

Aim Using chronic pre-pregnancy stress to establish a postpartum depression animal model, given a single YG,and acute ketamine was served as control, to explore the pathology of PPD and the anti-depressive mechanism of the YG on the PPD model on AKT/mTOR signaling pathway. Methods Thirty-two fe-male Balb / c were randomly assigned to two groups, the control group ( Control, Con) and the pre-pregnancy stressed group(Model,Mod) , which was subjected to 3 weeks chronic restraint stress. After the last stressor, the pre-pregnancy stressed group was housed with a male. After about 4 weeks later, the mice gave birth to pups. Then at 3 weeks postpartum, we tested the ma-ternal tail suspension test ( TST). Both YG and Ket-amine was single administered 24 hours before behavior test, with single saline for control group and PPD mod-el group. After TST,the mouse hippocampus were ex-tracted to detect the expression of AKT and mTOR. Results After 3 weeks postpartum, the model mice showed depression-like behaviors. Immobility in TST was significantly increased in vehicle groups(P <0. 01). Acute YG improved performance in the TST (P< 0. 01), which was similar to ketamine. And the PPD model mice group showed decreased phosphorylation of AKT and mTOR (P < 0. 01,P < 0. 01), compared to control group. A single dose of YG or ketamine normal-ized AKT/ mTOR signaling in the PPD model mice(P< 0. 01,P < 0. 01),( P < 0. 01,P < 0. 01). Conclu-sions Chronic pre-pregnancy stress can induce dams into postpartum depression and its mechanism maybe associated with down-regulating AKT/ mTOR signa-ling. Acute YG exerts fast antidepressant effect on this PPD model similar to ketamine, and its mechanism may be related to up-regulating AKT/ mTOR signaling in the hippocampus.

Objective To explore the relationship among depression,anxiety and social support in elderly patients in community outpatient clinic. Methods A total of 551 elderly outpatients from two com-munity health service centers of Hongkou District in Shanghai were evaluated with patient health question-naire-9 (PHQ-9),generalized anxiety disorder-7 (GAD-7),perceived social support scale( PSSS) for de-pression,anxiety,physical health and social support. Results The prevalence rates of depression and anxiety were 26. 1% and 17. 2%,respectively. The scores of PHQ-9 and GAD-7 were 2. 0(4. 0) and 1. 0(2. 0). There were statistically significant differences in the scores of family support,friend support,other support and social support among the elderly patients with different degrees of depression or anxiety (P<0. 01). Fam-ily support(B=-0. 196) and friend support(B=-0. 171) were protective factors of depression in elderly pa-tients in community outpatient clinic. Age,family support and friend support were protective factors of anxiety in elderly patients,while gender and fluctuation of physical diseases were protective factors of anxiety(P<0. 05). Con-clusions The depression and anxiety is intimately related to social support in elderly outpatients. Appropriate measures should be taken to optimize social support,mitigate bad mood negative improve their quality of life.

Objective : To explore the effect of miRNA-222-3p in endothelial progenitor cell-derived exosomes (EPCs-Exo) on skin wound healing in diabetic mice． Methods : Endothelial progenitor cell ( EPCs) derived from C57BL /6 mouse bone marrow were identified by fluorescence staining．Subsequently，EPCs-Exo isolated from the media of EPCs were identified，and high-throughput sequencing of EPCs-Exo miRNA was completed．The skin injury model of diabetic mice was established．According to different groups，the wounds were treated with externally ap- plied phosphate buffer solution ( PBS ) and EPCs-Exo ; Subcutaneous injection of PBS，agomiR-222-3p，and an- tagomiR-222-3p at the edge of the wound was performed continuously for 14 days，and the wound healing rate was observed．Meanwhile，immunofluorescence methods were used to investigate the changes in the expression levels of ROS，CD31，and VEGF in the wound margin tissue before and after treatment. Results : EPCs-Exo significantly ac- celerated skin wound healing in diabetic mice，reduced the level of ROS，and increased the expression level of VEGF and CD31 in the wound margin tissue (P＜0. 05) ．High-throughput sequencing showed that miRNA-222-3p was highly expressed in EPCs-Exo．Local subcutaneous injection of miRNA-222-3p into wound margin tissue signifi- cantly promoted the skin wound healing of diabetic mice，reduced the level of ROS，and increased the expression level of VEGF and CD31 in the wound margin tissue (P ＜0. 05) ． Conclusion MiRNA-222-3p promotes wound healing in diabetic mice and plays an important role in EPCs-Exo promoting wound healing.
