Aim To study the role of ubiquitin carboxyl terminal hydrolase L1 (UCH-L1)involved in the pro-tective effect of fluoxetine against monocrotaline-in-duced pulmonary arterial hypertension in rats.Meth-ods Monocrotaline (60 mg·kg -1 )was used to es-tablish pulmonary arterial hypertension in rats and low-dose (2 mg·kg -1 ·d -1 )or high-dose (10 mg·kg -1 ·d -1 )fluoxetine was applied to inhibit pulmonary ar-terial hypertension.The hemodynamics,morphology of pulmonary arterioles and lungs,UCH-L1 protein ex-pression and nuclear factor-κB (NF-κB)nuclear trans-location were observed.Results Monocrotaline not only increased pulmonary arterial pressure and promo-ted pulmonary arterial remodelling and lung inflamma-tion,but also down-regulated UCH-L1 protein expres-sion and increased NF-κB activity in lungs.Fluoxetine inhibited these changes in a dose-dependent manner. However,UCH-L1 protein expression of pulmonary ar-teries did not significantly change among different groups.Conclusion Fluoxetine inhibits monocrotal-ine-induced lung inflammation in rats,involved in NF-κB activity inhibited by up-regulated UCH-L1 protein expression.

Methods SD rats were randomly divided into 6 groups, control group, model group, fluoxetine group, Baishile Capsules high-, medium- and low-dose groups, with 10 rats in each group. The cums depression model was established, and gavage for medication was conducted at the same time for 21 days in a row. The behavioral changes of rats in each group were detected by the novel feeding experiment and Open-field experiment; monoamine neurotransmitter in serum were detected by ELISA; the expressions of PI3K, AKT and SGK1 in rat hippocampus were detected by immunofluorescence and Western blot test. Results Compared with the control group, feeding latency of rats in model group was significantly prolonged (P<0.01), horizontal and vertical activities were significantly reduced (P<0.01); the content of serum monoamine neurotransmitter decreased (P<0.01); the expressions of PI3K and AKT in hippocampus decreased, while the expression of SGK1 increased (P<0.01, P<0.05). Compared with the model group, Baishile Capsule high- and medium-dose groups can significantly shorten the incubation period of feeding rats (P<0.05), and increase the number of horizontal and vertical activities (P<0.01); the 5-HT and NE levels in serum were significantly elevated (P<0.05, P<0.01); the expressions of PI3K, AKT in hippocampal increased; the expression of SGK1 decreased (P<0.05, P<0.01). Conclusion Baishile Capsules can alleviate the depression like behavior in rat models, and regulate key factors of hippocampal PI3K signaling pathway, so as to exert antidepressant effects.

Objective To study the changes of behavior and depression-like classic indicators after hippocampal microinjection of K252a,and to establish a new animal model of depression.Methods SD rats were randomly divided into five groups,namely the control group,sham group,chronic stress depression model group,hippocampal of K252a microinjection group,and hippocampal microinjection K252a plus chronic stress group.Open field experiments,sucrose consumption test,and Morris water maze behavioral assay were used to assess the behavioral changes in the rats.ELISA was used to detect the plasma monoamine neurotransmitter,radioimmunoassay was used to determine the plasma CRH,ACTH,CORT contents,and western-blotting was performed to observe the protein expression of BDNF,CREB,ERK1/2,and BCL-2 in the hippocampus.Results Compared with the control group,the amount of activity,sugar consumption,learning and memory abilities were decreased(P<0.05 or P<0.01),also the serum monoamine neurotransmitters were decreased (P<0.01),HPA axis function was improved (P<0.01),and the expression of BDNF,CREB,ERK1/2,BCL-2 decreased in the CUMS group(P<0.05 or P<0.01),but there was no significant difference in the DMSO group.Compared with the DMSO group,the activity,consumption of sucrose,learning and memory ability were significantly decreased(P<0.05 or P<0.01),while the HPA axis function was increased (P<0.05 or P<0.01),the serum monoamine neurotransmitters decreased(P<0.05 or P<0.01),and the BDNF,CREB,ERK1/2,BCL-2 expressions in the hypocampus were significantly decreased(P<0.05 or P<0.01) in the K252a group and K252a + CUMS group.Compared with the CUMS group,the K252a group and K252a + CUMS group did not show significant changes in these parameters.Compared with the K252a group,these indicators were not significantly changed in the K252a + CUMS group.Conclusions The results of behavior,hematology,and molecular biology analysis show that this model has a great similarity to the classical model of CUMS in surface validity,construct validity,and functional validity.It may provide an alternative investigative technology platform for basic research and antidepressant drug screening.

Objective To investigate effects of Baishile Capsules on cAMP-CREB-BDNF signal pathway about hippocampal neurogenesis in model rats with chronic unpredicted stress depression. Methods SD rats were randomly divided into blank group, model group, fluoxetine hydrochloride group, and Baishile Capsules high, medium, and low dose groups. Chronic stress depression rat model was established by chronic and mild unpredictable stressors. All groups were given relevant medicine for 21 days. The open-field test, sugar consumption experiment, place navigation test, and space searching experiment were used to detect behavior changes of the rats. ELISA was used to detect content of corticosterone in plasma. The protein expressions of PKA, BDNF, and CREB were detected by immunohistochemical method. Results Compared with model group, Baishile Capsules high dose and medium dose groups could remarkably increase the number of vertical and horizontal activities and 1% sucrose partial eclipse. Platform latency and target quadrant searching time decreased significantly in Baishile Capsules high dose group (P<0.05), and content of corticosterone in plasma increased obviously (P<0.05) in Baishile Capsules all dose groups. Protein expressions of PKA, CREB, and BDNF in hippocampal DG and CA3 area increased significantly (P<0.05) in Baishile Capsules high dose group. Conclusion Baishile Capsules can promote hippocampal neurogenesis through the cAMP-CREB-BDNF signal pathway and realize anti-depression effect.

Objective To screen the optimized Buyang Huanwu Decoction (BYHWD);To verify it. Methods H2O2 was used to induce PC12 cell oxidative stress models. MTT method was used to determine the prevention effects of BYHWD at different concentrations (0.1, 0.2, 0.5, 1.0, 2.0, 3.5 mg/mL) on in vitro oxidative stress cell models to define the optimized concentration. Orthogonal design was used to divide BYHWD single medicine into decomposed BYHWD groups, control group (only with DMEM), normal group (without H2O2 and medicine processing), and model group, to investigate the protective effects on PC12 cells. Optimized BYHWD was screened to decide the compatibility ratio of each medicine. MTT was used to detect the cell survival rate in each group. Middle cerebral artery occlusion was used to replicate MACO rat models. SD rats were randomly divided into sham-operation group, model group, BYHWD group and optimized BYHWD high-, medium-and low-dose groups. Each medication group was given relevant medicine for gavage. The screened results were verified. Results Compared with other decomposed BYHWD groups, the protective effects of the compatibility of Astragali Radix+Chuanxiong Rhizoma+Pheretima on PC12 cells was the best (P<0.05), which was nearly equaled to BYHWD. Compared with the model group, BYHWD and the optimized one could evidently reduce cerebral cortex infarction area and improve the impaired brain edema (P<0.05), and the medium-dose group was the best. Conclusion The optimized BYHWD ratio is:Astragali Radix:Chuanxiong Rhizoma:Pheretima=10:3:1.

Lumican is a member of the small leucine-rich proteoglycan family, which is involved in cell processes related to tumorigenesis and development, such as epithelial-mesenchymal transition, cell proliferation, migration, invasion and adhesion. The expression of Lumican in different tumors is positively or negatively correlated with tumor progression, and can be used as a reference for tumor prognosis and efficacy evaluation. Further study of the correlation and potential mechanism between Lumican and tumor therapy resistance can provide new ideas for predicting clinical therapeutic efficacy.
