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.

The tail suspension test (TST), forced swimming test (FST) and chronic unpredictable mild stress (CUMS) model were used to evaluate the anti-depressant effect of supercritical CO2 extract from Compound Chaigui Fang (FFCGF). A nuclear magnetic resonance (NMR)-based metabonomics combined with multivariate statistical analysis was performed to explore the mechanism of FFCGF. Rats were conducted by CUMS procedure for 28 days and drugs were administrated at the same time. The body weight, sucrose preference, crossings and rearings in open-field tests were evaluated and the urine was collected simultaneously. The metabonomic profiles of rats' urine were analyzed by NMR and potential biomarkers were searched by multivariate statistical analysis. The results showed that administration of FFCGF significantly decreasing the immobility time in FST and TST and improving rats' body weight, sucrose preference, crossings and rearings in CUMS, which were indication that the anti-depressant effect of FFCGF was abvious. Significant differences in the metabolic profile of the CUMS treated group and the control group were observed, which were consistent with the results of behavioral tests. Decreased levels of acetic acid, succinic acid, 2-oxidation glutaric acid and citric acid and increased glycine and pyruvic acid in urine were significantly affected by the CUMS procedure and the 6 biomarkers were reversed evidently after administration of FFCGF. These changes were suggestion that the anti-depressant mechanism of FFCGF was associated with energy metabolism, lipid metabolism and amino acid metabolism.

BACKGROUND: Pathophysiological mechanism of local microenvironment is complex after central nerve injury; especially,both inflammatory reaction at an acute phase and formation of secondary glial scar have tremendous effects on effective regeneration of axon, regeneration and arrangement of local nerve cells, proliferation and migration of local stem cells;therefore, it becomes a basic reason for blocking nerve repair in an early period. Thus, how to effectively resist inflammatory factors in injured region at an acute phase and how to optimize microenvironment of neural regeneration are the most important strategies for repairing spinal cord injury in recent years.OBJECTIVE: To design, establish and screen the best expression of interleukin-6 receptor (IL-6R) α to inhibit shRNA adenovirus expression vector by using spinal cord injury models.DESIGN: Duplicative measurement study.SETTING: Department of Spine Surgery, the Second People's Hospital of Shenzhen.MATERIALS: A total of 40 healthy Wistar rats, either gender, 8-10 weeks old, were selected in this study. Rabbit-anti-rat glial fibrillary acidic protein (GFAP) antibody Ⅰ was provided by Santa Cruz Compan; siRNA eukaryon expression plasmid pGenesil (cohtaining green fluorescent expression system) was provided by Wuhan Jingsai Bioengineering Company.METHODS: The experiment was carried out in ImmuneOpening Laboratory, Basic Medical Faulty, Tongji Medical College, Huazhong University of Science and Technology, and Medica Laboratory Center, the Second People's Hospital of Shenzhen in November 2006. Three pairs of shRNA template which composed of 19 bp reverse repeated motif of IL-6 receptor (IL-6R) α target sequence with 9 bp spacer were designed and synthesized, then the recombinant adenovirus expression vectors with green fluorescence protein were constructed in vitro respectively. The acute spinal cord injury models were completed, and the adenovirus recombinants were regionally injected post 12 hours after spinal cord injury;in addition, the inhibitory effect of RNA interference (RNAi) on expression of IL-6R in local region after spinal cord injury were detected by using real-time fluorescence quantitative reverse transcription polymerase chain reaction (RT-PCR) and Western blot so as to screen adenovirus expression vector which had the best inhibitory effect on expression of IL-6R.MAIN OUTCOME MEASURES: Inhibitory effect of RNAi on expressions of IL-6R RNA and protein in local region after spinal cord injury.RESULTS: Sequence analysis showed that IL-6R-shRNA recombinant adenovirus expression vector was successfully constructed, and optimal IL-6R-shRNA recombinant adenovirus expression vector was screened by using real-time fluorescence quantitative RT-PCR and Western blot. The IL-6R expressions were 49% and 56% at the levels of mRNA and protein, respectively.CONCLUSION: The IL-6R--shRNA recombinant adenovirus expression vector is successfully constructed and screened.The gene expression of IL-6R can be highly inhibited after acute spinal cord injury.

Objective To explore the effects of NF-E2-related factor 2 (Nrf2) overexpression on mitochondrial biosynthesis and function in melanocytes.Methods An immortalized human vitiligo melanocyte cell line PIG3V was used in this study.An overexpression plasmid Nrf2-pEX-1 containing the full-length Nrf2 gene was constructed.PIG3V cells were divided into 3 groups:blank group receiving no treatment,control group transfected with the pEX-1 plasmid,overexpression group transfected with the Nrf2-pEX-1 plasmid.After transfection,real-time quantitative reverse transcription-PCR (RT-PCR) and Western blot were performed to determine the mRNA and protein levels of mitochondrial biosynthesis-related factors (including Nrf2,nuclear respiratory factor 1 (NRF1) and mitochondrial transcription factor A (TFAM)) respectively;RT-PCR was also conducted to measure the copy number of mitochondrial DNA (mtDNA),and flow cytometry to estimate mitochondial membrane potential (MMP);luciferase reporter system was used to estimate the intracellular adenosine triphosphate (ATP) level.Statistical analysis was carried out by using a two-sample t-test.Results After transfection,a significant increase was observed in the mRNA expression levels of Nrf2 and NRF1 at 24 hours (both P ＜ 0.001) and in those of Nrf2 and TFAM at 48 hours (both P ＜ 0.05),but no significant change was noted in the mRNA expression level of TFAM at 24 hours (P ＞ 0.05) or in that of NRF1 at 48 hours (P ＞0.05) in the overexpression group compared with the control group.In the case of Nrf2,NRF1 and TFAM protein levels,the overexpression group showed significant increases compared with the control group at 48 hours after transfection (all P ＜ 0.05),while no significant difference was noted between the two groups at 24 hours.Compared with the control group,MMP in the overexpression group increased by 2.313％ at 24 hours (t =5.546,P =0.005) and by 14.872％ at 48 hours (t =8.537,P =0.001) after transfection.Both the relative copy number of mtDNA and ATP level were similar between the overexpression group and control group at 24 hours after transfection (both P ＞ 0.05),but significantly higher in the overexpression group than in the control group at 48 hours (t =5.760,P =0.005;t =22.040,P =0.008).Conclusion Up-regulation of Nrf2 pathway can improve mitochondrial function and biosynthesis in PIG3V cells likely by promoting the expressions of mitochondrial biosynthesis-related genes and proteins.

Objective To investigate the relationship and mechanism of the serum vitamin D levels with insulin sensitivity and adipokines APN,RBP4,visfatin and TNF-α in patients with gestational diabetes mellitus(GDM). Methods A total of 101 patients with gestational diabetes( GDM group) and 50 pregnant women with normal blood sugar( control group) were recruited to detect the serum levels of correlative biochemical indexes,APN,RBP4,visfatin,TNF-α and 25OHD3 using an HPLC method. Twenty-four patients in the GDM group diagnosed with vitamin D deficiency(<25 nmol·L-1 ) were randomized to receive either 1,25(OH) 2D3(0. 25 μg·d-1) orally or no treatment. Serum levels of correlative biochemical indexes were detected after 1 month. Results GDM patients had 25OHD3 levels significantly lower than the control group(P<0. 05),APN levels lower than the control group,and RBP4,visfatin,TNF-α levels significantly higher than the control group(all P<0. 05). After 1 month of 1,25(OH) 2D3 treatment,HOMA-IR increased,while HOMA-β decreased. APN levels was positively correlated(r= 0. 526) with 25OHD3;RBP4,visfatin,TNF-α decreased and were negatively correlated with 25OHD3( r values were -0. 272,-0. 153,-0. 072). Conclusion Vitamin D can reduce the adipokines RBP4,visfatin,TNF-α,increase APN,and thus play a protective role for gestational diabetes.

AIM: To evaluate the safety, efficacy and stability of posterior chamber phakic intraocular lens ( ICL ) implanation and clear lens extraction for the correction of high myopia.
METHODS: The study enrolled 56 cases ( 100 eyes ) of high myopia. Group I comprised 32 cases ( 58 eyes ) receiving ICL implantation and Group II comprised 24 cases (42 eyes) undergoing clear lens extraction. In this study, we evaluated the two groups of subject's the visual and refractive results, intraocular pressure ( IOP ) , endothelial cell density ( ECD ) , anterior chamber depth ( ACD) , lens transparency, the surgical complications as well as visual adverse symptoms before and after surgery.
RESULTS: The postoperative subjects in group I and group II were followed, uncorrected vision acuity ( UCVA)>0. 5 were 69. 0% in group I and 71. 4% in group II after 3mo. UCVA>0. 5 were 72. 4% in group I and 73. 8% in group II after 1a. Predictability of the manifest spherical equivalent refraction within±1. 00D was achieved in 62. 1%of eyes in group I and 57. 1% in group II after 1a. The central vault of the ICL ( distance from posterior surface of ICL to the crystalline lens ) measured with anterior segment optical coherence tomography ( AS-OCT ) was 0. 35-0. 54 (0. 40±0. 16) mm. Twelve point one percent of eyes in group I and 7. 1% of eyes in group II had transient mild increase in IOP. Here were statistically significant differences between preoperative and postoperative ECD (P<0. 001 ). Complications of surgery: 1 eye had ICL spontaneous rotation, 2 eyes had anterior subcapsular cataract, 4 eyes noticed halos around lights at night in group I. Three eyes had posterior capsule mild opacification, 3 eyes noticed halos around lights at night, 12 eyes had difficulty in near vision in group II.
CONCLUSION: ICL implantation and clear lens extraction are effective, safe and predictable surgical option for the management of high myopia. No severe complications occurred, but its long time effect and safety still need more time to prove.
