The present study aims to predict the action targets of antidepressant active ingredients of Xiaoyaosan to understand the "multi-components, multi-targets and multi-pathways" mechanism. Using network pharmacology, the reported antidepressant active ingredients in Xiaoyaosan (saikosaponin A, saikosaponin C, saikosaponin D, ferulic acid, Z-ligustilide, atractylenolide I, atractylenolide II, atractylenolide III, paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid and pachymic acid), were used to predict the targets of main active ingredients of Xiaoyaosan according to reversed pharmacophore matching method. The prediction was made via screening of the antidepressive drug targets approved by FDA in the DrugBank database and annotating the information of targets with the aid of MAS 3.0 biological molecular function software. The Cytoscape software was used to construct the Xiaoyaosan ingredients-targets-pathways network. The network analysis indicates that the active ingredients in Xiaoyaosan involve 25 targets in the energy metabolism-immune-signal transmutation relevant biological processes. The antidepressant effect of Xiaoyaosan reflects the features of traditional Chinese medicine in multi-components, multi-targets and multi-pathways. This research provides a scientific basis for elucidation of the antidepressant pharmacological mechanism of Xiaoyaosan.

Objective To investigate the diagnostic value of contrast-enhanced ultrasound (CEUS), and compare it with contrast-enhanced CT(CECT). Methods Eighty-one focal liver lesions were evaluated with CEUS and CECT, diagnostic value of two modalities were calculated, vaseularity manifestations of two modalities in arterial phase were compared. Results The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of CEUS were 96.6 %, 86.9 %, 94.9 %, 90.9 %, 93. 80%, respectively, and the diagnostic value of CECT were 98.3%, 82. 6%, 93.4%, 95.0%, 93.8%, respectively. Among all the metastasis, hypervascular manifestation lesions in arterial phase of CEUS and CECT were 72% (18/25) and 32% (8/25)( P <0.05). Conclusions The diagnostic value of CEUS and CECT in focal liver lesions are comparably satisfying,and there is no significant difference between them, the combination use of two modalities would improve the diagnosis performance. CEUS can show more hypervaseular metastasis than CECT in arterial phase.

AIM: To summarize clinical characteristics and pathogenesis of iridocorneal endothelial syndrome ( ICE ) and investigate the treatment and prognosis.
METHODS:The clinical data of 12 cases (12 eyes) who received treatment in southwest hospital during Jun. 2007 to Feb. 2015 were analyzed retrospectively. The essential progressive atrophy of iris included 7 eyes, Chandler syndrome included 3 eyes, Congan - Reese syndrome included 2 eyes.
RESULTS: A total of 8 eyes were carried out once or multiple filtration surgery; 4 eyes were treated with glaucoma valve implantation. Postoperative follow- up time ranged from 15mo to 5y with the average of 30mo. Three months to 16mo after the surgery, the intraocular pressure of 4 patients were elevated again. Postoperative intraocular pressure was poorly controlled.
CONCLUSION:ICE syndrome is a group of clinically rare and serious eye disease. The excessive proliferation of ICE cells causes the existence of the corneal endothelial cells adhesion to the chamber angle and iris surface, which cause iris atrophy, secondary glaucoma, corneal endothelial decompensation. Currently, glaucoma filtration surgery and glaucoma valve implantation can only control intraocular pressure for several months, but the long-term prognosis is poor.

Transforming growth factor-?1 (TGF-?1) was reported to play an important role in the pathogenesis of asthma in many stu-dies.It can stimulate the growth of fibroblast and give rise to fibrosis of lung tissues.Many scholars think that TGF-?1 is closely related to airway remodeling.It is a breakthrough to aim at TGF-?1 to find a way to intervene remodeling in asthma.Glucocorticoid (Dexamethasone and Budesonide) can have an impact in some extent to airway remodeling.In addition,interferon-? and some traditional chinese medicine such as ligustrazine,tripterygium wilfordii and ginkgo maybe effective,they all may ameliorate the progression of airway remodeling following redu-cing partial airway TGF-?1 expression.

OBJECTIVETo explore the effect of Modified Hangqi Chifeng Decoction (MHCD) on levels of collagen type IV (Col IV), matrix metalloproteinase-2 (MMP-2), tissue inhibitor of metalloproteinase-2 (TIMP-2) in extracellular matrix (ECM) of glomerular mesangial cells (GMCs) in LPS induced mice.
METHODSNormal serum and telmisartan, high, medium, low dose MHCD containing serums were prepared by using serum pharmacology method. GMCs were cultured in vitro. The proliferation of mesangial cells were induced using LPS as stimulating factor. GMCs were divided into six groups, i.e., the normal group, the model group, the telmisartan group, high, medium and low dose MHCD groups. Col IV content in the supernatant of mesangial cells was detected using ELISA. Protein expressions of MMP-2 and TIMP-2 were detected using Western blot.
RESULTSCompared with the normal group, Col IV content obviously increased in the model group after 72-h LPS stimulation; protein expressions of MMP-2 and TIMP-2 were obviously up-regulated, and MMP-2/TIMP-2 ratio was down-regulated in the model group (P < 0.01). Compared with the model group, Col IV content obviously decreased in high and medium dose MHCD groups and the telmisartan group (P < 0.01); protein expressions of MMP-2 were obviously down-regulated in medium and low dose MHCD groups (P < 0.01, P < 0.05); the protein expression of TIMP-2 was obviously down-regulated in high, medium, low dose MHCD groups and the telmisartan group (P < 0.01). The pro- tein expression of TIMP-2 was obviously lower in the high dose MHCD group than in the low dose MHCD group (P < 0.01). MMP-2/TIMP-2 ratio was obviously up-regulated in the telmisartan group, high and medium dose MHCD groups (P < 0.01).
CONCLUSIONMHCD could regulate disordered MMP-2/TIMP-2 ratio in LPS induced ECM, inhibit excessive production of Col IV in ECM, promote the degradation of ECM, reduce the accumulation of ECM, thereby, delaying the process of glomerular sclerosis.
