Objective To establish a type of porcine model for controlled Cardiac Deceased Donor.Method Using the wuzhishan miniature pig 2 ~ 4 months of age.After intravenous general anesthesia and respiratory,after open heart surgery to produce myocardial infarction model,to heartbeat stop completely,stop breathing machine and drug support,so we established a miniature pig cardiac death donor model.Record during the heart rate,systolic pressure,diastolic blood pressure,central venous blood pressure,blood oxygen saturation and regularly take on blood gas analysis.Before cardiac arrest,monitoring hemodynamic,blood gas analysis,and the time of death before the circulatory failure.After cardiac arrest respectively 0 min,15 min and 30 min,perfusion for donor organs (liver/kidney),get the pig's liver/kidney in the different time of the groups,observed the pathological changes of liver/kidney tissues by HE staining.Result The heartbeat stop completely occurs 7 ± 0.17 minutes after left descending coronary artery ligation and cease of assisted respiration in the different groups,systolic pressure,diastolic blood pressure,central venous pressure,blood oxygen saturation,CO2 partial pressure changed significantly;Immediately after cardiac arrest for compared group (0 min),schemia-reperfusion that group of 15 min after cardiac arrest injury is obvious,ischemia-reperfusion that group of 30 min after cardiac arrest injury is further.Conclusion Miniature pig donor model obtained in this method respiratory cycle failure stability,can be controlled,no adverse drug reactions,the organ ischemia-reperfusion injury caused by repetitive is better.

Objective To study the pathological characteristics of skeletal muscle in patients with polymyalgia rheumatica(PMR).Methods Thirteen patients were diagnosed PMR according to the diagnostic criteria described by Bird in 1979.The onset of disease was between 49-78 years of age (median 60.3 years).All of them showed continuous symmetric myalgia with markedly elevated erythrocyte sedimentation rate(ESR).Five patients had mild fever and 8 patients had elevated C-reactive protein(CRP).Electromyogram(EMG)showed myogenic pattern in 2 patients.Only 1 patient showed anemia and 2 patients had mild elevated creatinine phosphokinase.None of them showed evidence of temporal arteritis.Biceps brachii muscle biopsies were performed in all patients before corticosteroid therapy.Results The typeⅡmuscle fiber atrophy was observed in all patients.Moth-eaten changes appeared in 8 cases,increased intramuscular lipid drops in 8 cases and ragged red fibers(RRF)in 3 cases of them.After steroid therapy,all patients showed improvement of myalgia and normal ESR as well as CRP.Conclusions The main symptoms of the patients are myalgia and abnormal ESR.Some patients have high level of CRP and abnormal EMG.Anemia and temporal arteritis are less frequent.The main myopathological changes were typeⅡmuscle fiber atrophy.Some patients have moth-eaten changes.More lipid drops and RRF indicate abnormal metabolism of skeletal muscle.

Objective: To compare tea polysaccharides(TPS) characteristics and their role in scavenging free radicals and reducing blood glucose(BG) in diabetic mice(DM). Methods: TPS was extracted from green,Oolong and black tea which were made from the same fresh leaves from Hubei,Fujian and Yunnan. Then the recovery rate of TPS, contents of neutral sugar, uronic acid and protein were analysed, and scavenging rate of -2Oand 稯H in vitro and hypoglycemic effect were also determined. Results: 1. The yield and contents of neutral sugar, uronic acid and protein of green tea TPS were the highest, and those of black tea TPS were the lowest. Oolong tea TPS acted the best in scavenging-2O and 稯H . 2. The hypoglycemic effect of TPS from Hubei tea was the best . The effect of TPS extracted from semi-fermented Oolong tea and fermented black tea was better than that of non-fermented green tea. 3. There were obvious differences in yield, free radical scavenging rate and effect of reducing BG among TPS extracted from tea in different regions. TPS extracted from Fujian tea had the best effect in reducing BG,but that from Yunnan tea had not. Conclusion: There was remarkable effect of region and process on physico-chemical characteristics,effect of scavenging radical and reducing blood sugar TSP.

Hydroxycinnamoyl-CoA:shikimate/quinate hydroxycinnamoyltransferase(HCT) is an key enzyme involved in the biosynthesis of chlorogenic acid in Lonicera japonica. In this study, eight putative HCT genes were cloned with RACE (rapid amplification of cDNA ends) technology based on the analysis of transcriptome in L. japonica. Among them, one was suggested as HCT gene (LjHCT) in L. japonica through analysis of sequence similarity, physical and chemical properties, and domain conservation of the proptein. LjHCT gene containing 1 275 bp encodes a protein with the molecular weight of 47 kDa. These results will provide foundation for exploring the function of LjHCT in Lonicera japonica.

OBJECTIVETo look for the active fraction of ethanol extract of Genkwa Flos (EGF) induced hepatotoxicity and develop an UPLC fingerprint of the active fraction.
METHODTarget fraction of EGF induced hepatotoxicity was guided by the serum biochemical and histopathology methods. The UPLC method was applied to establish the chromatographic fingerprint. The separation was achieved on a BEH C18 column (2.1 mm x 50 mm, 1.7 microm) with a mobile phase consisting of acetonitrile and water containing 0.05% phosphate acid running gradient elution. The detection was carried out at 210 nm and the analysis was finished within 10 min.
RESULTThe chloroform phase of EGF could be responsible for the hepatotoxicity of this herb. The common mode of the UPLC fingerprint was set up under the established condition. There were 17 common peaks in fourteen batches of herbs, eight of which were identified, and the similar degrees of the fourteen batches to the common mode were between 0.890-0.999.
CONCLUSIONIt is easy to locate the chloroform extraction of EGF with hepatotoxicity. And the UPLC fingerprint was developed for the above fraction, which could provide valuable references for safe and effective clinical use of EGF.

Clinical reports on cardiac syndrome X (CSX) have been increasing in recent years. In general, CSX does not increase the cardiovascular mortality, but it can affect the patient's quality of life (QOL) and increase the incidence rates of cardiovascular and cerebrovascular events. Although a variety of drugs and therapies have been utilized in the clinical treatment, the management of CSX still represents a major challenge due to its unclear pathogenesis. It is necessary to explore more effective treatment programs. Many attempts have been made on trials of the Chinese medicine (CM) treatment for CSX and proved that CM has a certain advantage in efficacy to improve clinical symptoms and QOL. CM may provide a new approach for the effective treatment of CSX.
