Objective To study the protective effects of propofol against ischemia/reperfusion injury in rat lung. Methods Rat model of pulmonary ischemia/reperfusion injury was used in this study. Rats were randomly divided into three groups, including sham opera-tion group (group A), iachemia/reperfusion group (group B) and propofol group (group C), 15 rats in each group. The concentration of tumor necrosis factor -α and interleukin-6 in bronchoalveolar lavage fluid (BALF) were measured by enzyme linked immunosorbent assay (ELISA). Then blood gas analysis, lung wet/dry (W/D) weight ratio were detected in each group. Results Propofol could significantly improve PaO2, reduce the W/D value and the contents of TNF-α and IL-6 in BALF. Conclusion Propofol effectively suppressed the pro-duction and release of inflammatory cytokine, therefore it can protect the lung from isehemia/reperfusion injury.

Danhong injection is a compound preparation of traditional Chinese medicine Salvia miltiorrhiza and Carthamus tinctorius, and has been widely applied in treating coronary heart diseases and ischemic encephalopathy in clinic. Despite the complexity of its chemical compounds and the diversity of targets, especially in system biology, there have not a report for its action mechanism as a whole regulatory biological network. In this study, protein data of S. miltiorrhiza and C. tinctorius were searched in TCMGeneDIT database and agilent literature search (ALS) system to establish the multi-component protein network of S. miltiorrhiza, C. tinctorius and Danhong injection. Besides, the protein interaction network was built based on the protein-protein interaction in Genecards, BIND, BioGRID, IntAct, MINT and other databases. According to the findings, 10 compounds of S. miltiorrhiza and 14 compounds of C. tinctorius were correlated with proteins. The 24 common compounds had interactions with 81 proteins, and formed a protein interaction network with 60 none-isolated nodes. The Cluster ONE module was applied to make an enrichment analysis on the protein interaction network and extract one sub-network with significant difference P <0.05. The sub-network contains 23 key proteins, which involved five signaling pathways, namely Nod-like receptor signaling pathway, epithelial cell signaling in helicobacter pylori infection, Toll-like receptor signaling pathway, RIG-I-like receptor signaling pathway and neurotrophin signaling pathway through KEGG signaling pathway mapping. In this study, the computational system biology approach was adopted to preliminarily explain the molecular mechanism of main compounds of Danhong injection in preventing and treating diseases and provide reference for systematic studies on traditional Chinese medicine compounds.

Objective To analyze the effect of conductive education combined with massage on activity of children with severe cerebral palsy. Methods 11 children (7 males and 4 females) with cerebral palsy receiving rehabilitation therapies in CereCare Wellness Centre of Xuhui, Shanghai from April to October 2010 were enrolled in this study. The type of cerebral palsy was as follows: 7 tetraplegia, 1 diplegia,2 athetoid, and 1 dystonia. The average age was 7.47 years, ranging from 4.7～11.9 years. The participants were divided randomly into 2groups. 5 children in group A accepted conductive education and massage therapy in the first 3 months, and then accepted routine rehabilitation therapies in the next 3 months. 6 children in group B accepted routine rehabilitation therapies in the first 3 months, and then accepted conductive education and massage therapy in the next 3 months. The phase of conductive education combined with massage was called intervention period, and the phase of routine rehabilitation therapies was called contrast period. The gross motor function was assessed with Gross Motor Function Measure Scale (GMFM), while the fine motor function was assessed with Fine Motor Function Measure Scale (FMFM).Pediatric Evaluation of Disability Inventory (PEDI) was used to assess activities of daily living. The different effects between conductive education combined with massage and routine rehabilitation therapies were compared. Results The scores of GMFM and FMFM both increased in intervention period, while both decreased in contrast period. The score of FMFM increased significantly (P<0.05). The scores of PEDI changed without statistical significance. Conclusion Conductive education combined with massage may increase the fine motor function of children with severe cerebral palsy compared with routine rehabilitation therapies.

In situ end-labeling of DNA fragments (TUNEL) was used to detect SMC apoptosis and immunohistochemical staining was applied to investigate the expression of SMC apoptosis markers(bcl-2,bax),proliferating cell nuclear antigen (PCNA) and ?-actin. Results TUNEL-positive and PCNA-positive SMC reached the maximum at 2～3 week and 1 week respectively;The count of TUNEL-positive SMC was less than PCNA-positive SMC during the period of day 3 to 1 week and that was vice versa from 2nd to 4th week with SMC amount significantly decreased;Bcl-2 and bax protein was strongly expressed at 1 week and 3 week after operation(all P

To establish the online two-dimensional liquid chromatography by using double gradient liquid chromatography system and UV detector, in order to simultaneously determine the content of paeoniflorin, paenol, amygdaloside and cinnamic acid. A pump of the two-dimensional liquid chromatography was adopted as the one-dimensional separation pump. C18 (3.0 mm x 150 mm, 3 microm) was used as the analytical column, with acetonitrile as the organic phase and 0.08% phosphoric acid + 0.08% triethylamine as the aqueous phase for gradient elution at the flow rate of 0.5 mL x min(-1). Another pump of the two-dimensional liquid chromatography was adopted as the two-dimensional separation pump. PAII C18 was used as the analytical column, with acetonitrile as the organic phase and 20 mmol, pH 3.0 monopotassium phosphate as the aqueous phase for gradient elution at the flow rate of 0.8 mL x min(-1). The detection wavelengths were set at 218, 230, 275 nm by using wavelength time-switching program. The linearity range of paeoniflorin, amygdaloside, paeonol and cinnamic acid were 5.55-222 (r = 0.999 7), 6.6-264 (r = 0.999 8), 3.3-132 (r = 0.999 5) and 0.315-12.6 mg x L(-1) (r = 0.999 7), respectively. The average recoveries of the four components were between 96.12% and 103.9%. The experiment proved that this method was so rapid and accurate in determination results that it could be used for evaluating drug quality.

Objective:To investigate clinical features of distant metastases ( DM ) and analyze clinico-pathologic risk factors associated with DM from salivary gland carcinomas after being treated by surgery combined with 125 I internal brachytherapy. Methods: Between October 2001 and March 2010, 197 pa-tients with salivary gland carcinoma were treated by surgery combined with 125 I internal brachytherapy and had follow-up for 2 years or more. Univariate and multivariate analyses were performed to evaluate clini-copathologic risk factors that might influence the risk of distant metastases. Results:DM occurred in 28 of 197 patients (14. 2%). The commonest site of distant metastases overall was the lung 89. 3% (25/28), followed by bones 17. 9% (5/28) and liver (4/28). DM developed after an average interval of (44. 2 ± 45. 8) months from the time of initial diagnosis, and the mean interval was 64 months. The average time to death after the diagnosis of DM was only (9. 7 ± 13. 4) months, and the mean time was 12 months. The 3-year locoregional control rate and survival rate were 90. 8%, and 87. 8% respectively,and the 5-year ones 84. 0% and 81. 0%, respectively. Univariate analyses revealed that the risk of distant metasta-ses was significantly influenced by locoregional tumor failure (F=26. 997,P<0. 01) and histologic dif-ferentiation (F=1. 592,P<0. 01). Multivariate analysis of freedom from distant metastases revealed that locoregional control (F=29. 332,P<0. 01) significantly influenced this end point. Conclusion: Sali-vary gland carcinoma could achieve high local control rate after being treated by surgery combined with 125 I internal brachytherapy, and the average interval from diagnosis to DM was prolonged, DM was signifi-cantly influenced bylocoregional control.
