Objective To explore the myocardial damage and the changes of MB isoenzyme of creatine kinase(CK-MB) and cardial troponin I(cTnI) of rat with endotoxemia at early stage.Methods Sixty SD rats were randomly divided into lipopolysaccharide(LPS) group(LPS group,n=48) and control group(n=12).Rats in LPS group were injected intraperitoneally with LPS(5 mg/kg) and then divided into 6 subgroups according sacrificed time after injection(0.5,1.0,2.0,3.0,12.0,24.0 h).CK-MB/ cTnI in blood was determined with chemiluminescent technique and myocardial pathological damage was observed under the light and transmission electron microscope.Control group was subjected to normal sodium and divided randomly into the same subgroups too.Results The rat diminished their action after beening injected endotoxin 15 minutes,and their reaction were slow.One hour later,they were short of action and reaction.Three hours later,they almost did not move at all,and the glossiness of their pelage were faint.Twenty-four hours later,their foodintake was diminished,their shout were weakened,and their response to stimulus were very thin,the glossiness of pelage were insufficient.Compared with control group,CK-MB increased significantly at 1.0,2.0,3.0,12.0,24.0 h(Pa

To study the effect of total matrines and extracts from Periplaneta americana on negative endometrial cancer cell JEC of progesterone receptors. After detecting the effect of total matrine, extracts from P. americana and their combination on JEC cells' growth inhibition, cell cycle, P53 and c-erbB-2 gene protein expressions through MTT, flow cytometry instrument and Western blot method, the author found that, (1) MTT: total matrines and extracts from P. americana could inhibit the growth of JEC cell, with significant increase in the inhibitory effect in the combination group. (2) Flow cytometry instrument: the cell cycle at G0/G1 increased after the treatment with total matrines, the cell cycle at G2/M increased after the treatment with extracts from periplaneta americana, and the ratio of G0/G1 cell cycle in the combination group was significantly higher than the other groups, with inhibition in cell growth and statistical difference in inter-group comparison (P < 0.05). (3) Western blot: the expression level of P53 increased and c-erbB-2 decreased after the treatment with total matrines, extracts from P. americana and their combination on JEC cell, with statistical difference in inter-group comparison (P < 0.05). The above results suggested that total matrines, extracts from P. americana and their combination could induce cell cycle arrest and inhibit the growth of JEC cell by up-regulating P53 and down-regulating the c-erbB-2 level.

Background Experimental study showed that heparanase (HPA)is overexpressed in choroidal neovascularization,suggesting that it may play a role in the pathogenesis of angiogenesis.To certify HPA inhibitor suppress the formation and development of new blood vessel has an important significance for the treatment of choroidal neovascularization.Objective The aim of this study was to investigate the effect of HPA inhibitor on the proliferation of human umbilical vein vascular endothelial cell (UVEC) and the expression of HPA.Methods Hunan UVEC was primarily cultured and passaged and the third generation cells were used in the experiment.Phosphomannopentaose sulfate (PI-88) solution,a HPA inhibitor,was prepared with endothelial cell medium and the end concentrations were 400.00,200.00,100.00,50.00,25.00,12.50,6.25 mg/L respectively.The cells were treated with PI-88 solutions for 24,48 and 72 hours.The growth and proliferation of human UVEC were analyzed using MTT colorimetric assay at absorbance 570 nm.The expression of HPA in the cells was detected by immunochemistry in 48 hours after addition of PI-88.Results Cultured human UVEC showed the fusiform and polygon in shape.The A570 values of human CVEC were significantly different among various concentrations of PI-88 groups (F=2.721,P=0.053 ) and different action time (F=9.656,P =0.002).When PI-88 was administered for 24 hours,the A570 values of human UVEC were insignificantly altered in comparison with the one without PI-88 culture group (P＞0.05 ).However,in 72 hours after experiment,the A570 values were significantly declined as the PI-88 concentration was ＞50.00 mg/L ( P＜0.05 ).When PI-88 was administered for 48 and 72 hours,the A570 values of human UVEC were significantly higher than those of 24 hours in ＜50.00 mg/L groups (P＜0.01 ),but no statistical differences were seen in ＞100.00 mg/L groups among various time points (P＞0.05 ).HPA was intently expressed in the cytoplasm of human UVEC.However,at 48 hours after addition of ＞25.00 mg/L PI-88,the HPA expression was obviously weaker.Conclusions PI-88 can suppress the growth and proliferation of human UVEC at the dose-and time-dependent manner by downregulating the expression of HPA in the cells.

OBJECTIVETo observe the clinical effect of Shugan Yiyang Capsules combined with sertraline in the treatment of premature ejaculation (PE).

METHODSWe randomly assigned 192 PE patients to receive sertraline hydrochloride 50 mg qd (control group, n = 96) or sertraline hydrochloride 50 mg qd plus Shugan Yiyang Capsules at the dose of 4 capsules tid ( combination therapy group, n = 96) , both for 6 weeks. We compared the intravaginal ejaculatory latency time (IELT) and Chinese Index of Premature Ejaculation ( CIPE) scores between the two groups of patients before and after medication and at 6 weeks after drug withdrawal.

RESULTSCompared with the baseline, the IELT was significantly increased after 6 weeks of medication in the combination therapy group ([1.41 ± 0.53] vs [6.69 ± 3.56] min, P < 0.05) and the control group ([1.43 ± 0.48] vs [5.37 ± 2.91] min, P < 0.05), and so was the CIPE score in the former (9. 80 ± 2.06 vs 21.62 ± 4.76, P < 0.05) and the latter group ([9.41 ± 1.97] vs [20.85 ± 4.83] , P < 0.05). In comparison with the pre-medication indexes, the IELT ([3.77 ± 1.63] min) and CIPE score (16.92 ± 3.37) of the combined therapy group were remarkably improved at 6 weeks after drug withdrawal (P < 0.05), but not those of the control ([1.19 ± 1.34] min and 10.59 ± 2.38, P > 0.05).

CONCLUSIONShugan Yiyang Capsules combined with sertraline have a definite and lasting effect on premature ejaculation.

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.

OBJECTIVETo observe the clinical efficacy and safety of sildenafil in the treatment of high altitude heart disease associated with severe pulmonary arterial hypertension (PAH) in children.

METHODSFifty children (aged 2 months to 2 years) with high altitude heart disease associated with severe PAH, who were continuously transferred to the Intensive Care Unit between January 2011 and October 2013, were randomly assigned to observation and control groups. The control group was given conventional treatment, while the observation group received oral sildenafil [1 mg/(kg . d)] three times daily for 7-10 days in addition to the conventional treatment. Before and after treatment, hemodynamics, blood gas, routine blood parameters, and blood biochemical parameters were recorded.

RESULTSAfter treatment, the observation group had a significantly higher decrease in mean pulmonary artery pressure and significantly higher increases in arterial partial pressure of oxygen, cardiac output, cardiac index, and oxygenation index compared with the control group (P<0.05). In the observation group, there were no significant changes in mean arterial pressure, routine blood parameters and blood biochemical parameters (P>0.05), and no obvious adverse reactions were found.

CONCLUSIONSFor children with high altitude heart disease associated with severe PAH, sildenafil can effectively reduce pulmonary artery pressure and improve cardiac function and does not cause adverse reactions. This therapy has good safety according to the preliminary evaluation.
