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.

Due to its effect of systems regulation and promotion on body, Ginseng is always referred to be long-term used as a dietary supplement. But it was still unclear about its target of the tonic effects and also the side-effects long-term use may bring. Urine metabolomic method is suitable for long-term studies of pharmaco-dynamics, pharmacology and toxicology of traditional Chinese medicine because of its characteristics of non-invasive and monitoring the whole-body metabolism. This study was designed to detect the dynamic variation of rat urine metabolome along with a long-term administration of total ginsenosides using GC-TOF based metabolomic technology. Our result showed that either short-term or chronic administration of ginsenosides did not impact the rat urine metabolome significantly (as the PCA subgroup was not successful). By comparison, the short-term (1-3 w) dose of ginsenosides had the biggest metabolic influence including TCA cycle, catecholamines and neurotransmitter amino acids. Medium-term (6-10 w) dose had a gradually lower effect and long-term (27 w) dose almost had no effect. Our study indicates that both short and long-term administration of ginsenosides showed almost no obvious side-effect on the experimental animals.

AIM To investigate the effect of fenofibrate and simvastatin on the serum free fatty acids of alcoholic fatty liver in rats. METHODS The rat model of alcoholic fatty liver was reproduced by chronic ethanol ingestion plus olive oil diet. The model rats were divided into three groups as follows: finofibrate treatment group(finofibrate 80 mg?kg -1 po, once a day),simvastatin treatment group (simvastatin 4 mg?kg -1 po, once a day)and control group without either above-mentioned treatment. Experimental rats were treated for four weeks and then sacrificed for blood sampling. Serum free fatty acids were analyzed by gas chromatography. RESULTS Fenofibrate significantly ameliorated the decrease in polyunsaturated fatty acids induced by ethanol [oleic acid:(38.212?7.788) ?g?L -1 vs (31.620?6.142) ?g?L -1,linoleic acid:(37.269?8.065) ?g?L -1 vs (30.254?9.063) ?g?L -1,arachidonic acid:(11.646?2.601) ?g?L -1 vs (9.012?1.236) ?g?L -1] accompanied by the improvement of the fat infiltration of the liver, but demonstrated no effect on the increase in serum saturated fatty acids by ethanol. In the contrast, simvastatin can aggravate the decrease in polyunsatrurated fatty acids and significantly increase the levels of satrurated fatty acids in serum induced by ethanol along with the pathological aggravation of alcoholic fatty liver. CONCLUSION The results of present study revealed that fenofibrate and simvastatin exerted different effect on the serum free fatty acids of alcoholic fatty liver. Polyunsatrurated fatty acids in the serum play an important role in the pathogenesis and treatment response of alcoholic fatty liver.

Objective To study the changes of PI3K/Akt/GSK3β signaling pathway during resuscitation with neck cooling in order to explore the relationship between the protective effect of neck cooling and the phosphorylation of PI3K/Akt and GSK3β.Methods Thirty rabbits were randomly(random number) divided into five groups, and models of cadiac arrest were induced by ventricular fibrillation(VF, the positive electrode in the right ventricle and negative pole on the apex of heart) for 4 min.In sham group,a electrode was placed into right ventricle without electric current conducted, and CA was not induced.The rabbits were sacrificed and specimens were taken at 24 hours after modeling.In normothermia treat group(NT group),resuscitation was carried out to restoration of spontaneous circulation(ROSC),and the rabbits were sacrificed and specimens were taken at 24 hours after modeling.In intra-arrest therapeutic hypothermia group (IATH group), rapid neck cooling was initiated at the same time with CPR,and the target brain temperature was set at 34 ℃ maintained for 4 hours after ROSC.Rabbits were sacrificed and specimens were taken at 24 hours after modeling.In recovery period cooling + LY294002 group(PATH+LY294002 group), LY294002 was injected intra-ventricularly at 20 minutes before resuscitation.Rapid neck cooling was started at the same time with CPR,and the target brain temperature was set at 34 ℃ maintained for 4 hours after ROSC.The rabbits were sacrificed and specimens were taken at 24 hours after modeling.In post-arrest therapeutic hypothermia group (PATH group), rapid neck cooling was begun after CPR for 1 hour,and the target brain temperature was set at 34 ℃ maintained for 4 hours after ROSC.The rabbits were sacrificed and specimens were taken at 24 hours after modeling.Animals were sacrificed by using overdose anesthetic drug.Western blot was used to detect the level of Akt p-Akt GSK-3β p-GSK-3β (ser9) protein, and TUNEL was used to observe apoptosis of tissues in each group.Multiple comparisons were performed with one-way analysis of variance (ANOVA).Results Compared with Sham group, Akt (Thr-308) phosphorylation (P-AKT) and P-GSK-3β levels in the brain neuron cytoplasm in 24 hours after CPR resuscitation in NT group was significantly reduced, and showed a gradual reduction trend (P<0.05);the P-AKT and P-GSK-3β levels in the brain neuron cytoplasm in 24 hours after CPR resuscitation in IATH group were significantly enhanced compared with NT group (P<0.05);the levels of these two kinds of protein at one hour after resuscitation in PATH group were significantly enhanced compared with NT group (P<0.05), but lower in IATH group.Intra-ventricularly injection of LY294002 made the effect of hypothermia lost, indicating that LY294002 inhibited the phosphorylation of Akt.Apoptosis cells were significantly reduced in IATH group and normothermia theatment group compared with PATH group and LY294002 group(P<0.05).Conclusions Neck cooling can reduce apoptosis in rabbit brain cells after recovery, and the protective effect on brain is best in intra-arrest therapeutic hypothermia group.LY294002 specifically block the PI3K/Akt pathway, and the protective effect of cooling on the brain can be abolished,indicating hypothermia protects the neurological function via activation of PI3K/Akt pathway.Neck cooling protects the neurological function by activating PI3K/Akt/GSK-3β, promoting the Akt activation, and increasing the expression of P-GSK3β.Specific Akt inhibitor LY294002 inhibits Akt phosphorylation of brain tissue recovery and further inhibit the phosphorylation of GSK-3β, thus abolishing protective effect of cooling on neurological function.

OBJECTIVE:
To investigate the clinical application and efficacy of 125Ⅰ radioactive seeds implantation in the treatment of recurrent salivary gland carcinoma after external radiotherapy.
METHODS:
From July 2004 to July 2016, 43 cases of recurrent salivary gland carcinoma of the neck after external radiotherapy or surgery combined with external radiotherapy were treated. According to the conventional segmentation radiotherapy for head and neck cancer (once a day, 1.8-2.0 Gy each time, 5 days per week), the cumulative radiation dose of the patients in this group was calculated. In the study, 26 patients received 50-60 Gy, 7 patients received less than 50 Gy, 4 patients received 60-70 Gy, and 6 patients received more than 80 Gy (range: 80-120 Gy). The interval between the last external irradiation and local recurrence was 4-204 months, and the median interval was 48 months. Among them, 25 cases were treated with 125Ⅰ radioactive seeds implantation only and 18 cases were treated with 125Ⅰ radioactive seeds implantation after operation. The prescription dose was 100-140 Gy. The control rate, survival rate and disease-free survival rate were recorded to evaluate the side effects.
RESULTS:
The median follow-up time was 27 months (ranging from 2.5 to 149.0 months). Among them, the median follow-up time of adenoid cystic carcinoma patients was 31 months (range: 2.5-112.0 months), and the median follow-up time of mucoepidermoid carcinoma patients was 18 months (range: 5-149 months). The local control rates for 1, 3 and 5 years were 66.5%, 48.8% and 42.7%, respectively. The 1-, 3- and 5- year survival rates were 88.0%, 56.7% and 45.8%, respectively. The disease-free survival rates of 1, 3 and 5 years were 58.3%, 45.4% and 38.1%, respectively. There was no statistically significant difference in local control rate, survival rate, and disease-free survival between the radioactive seeds implantation group and the radioactive seeds implantation group after surgical resection. There were 2 cases of acute radiation reaction Ⅰ/Ⅱ and 3 cases of reaction Ⅲ or above. In the late stage of radiotherapy, there were 8 cases with Ⅰ/Ⅱ grade reaction and 3 cases with Ⅲ grade or above reaction. The incidence of radiation reactions of Grade Ⅲ and above was 7%.
CONCLUSION
125Ⅰ radioactive seeds implantation provides an alternative method for the treatment of recurrent salivary gland carcinoma after external radiotherapy. The local control rate and survival rate are improved on the premise of low incidence of side effects.
