A new method was developed for the separation and determination of inosine monophosphate (IMP) by ion chromatography (IC) with suppressed conductivity detection. Separation was achieved on an anion-exchange column Ionpac AS11-HC of high capacity within a short time. 30 mmol/L KOH produced by an EGC-KOH eluent generator was used for isocratic elution. No interferences existed between the seven common inorganic anions and IMP. Under the optimum conditions, the linear range of the calibration curve for IMP was 1. 0-200 mg/L, with correlation coefficient ( R2 ) of 0. 999. The relative standard deviations (RSDs) for retention time, peak height and peak area of IMP were 0. 16%, 0. 94% and 0. 86%, respectively, indicating good reproducibility of the method. The method was successfully applied to the determination of IMP in meat products, with spiked recovery ranging from 86. 0% to 110. 0%. This simple, accurate and reliable method could be served as a rapid and effective analytical tool for meat flavoring research.

Objective To investigate the effects of ischemic postconditioning (Post) on myocardial cell apoptosis and expres- sion of Bcl-2 and Bax protein during ischemia/reperfusion period in rabbits.Methods Eighteen rabbits were randomly allocated to three groups (6 in each group),sham operation (group S),ischemia/reperfusion group(group IR) and ischemic postconditioning group(group Post).Group IR and group Post were subjected to 15 minutes of left anterior descending coronary artery occlusion followed for 30 minutes of reperfusion.Ischemic postconditioning was achieved by three 30 seconds cycles of reperfusion,each followed by 30 seconds ischemia.Cardiomyocyte apoptosis were determined by in situ TDT-mediated dUTP nick end labeling (TUNEL) and DNA electrophoresis.The expression of Bcl-2 and Bax proteins in apoptotic myocardial cells were detected by immunohistochemistry sepa- rately.Results Compared with group IR,apoptotic index was significantly reduced in group Post [(28.06?2.92) % vs.(55.70? 13.96)%,P

Objective To explore the changed status of the intestinal flora microecology in the model infant rats with irritable bowel syndrome(IBS) by integrative method.Methods To establish 20 infant rats model with IBS.The IBS rats were randomly divided into the treatment group A with bifico and positive control group B,and another 10 infant rats which grew up regularly were taken as negative control group C.The feces smear staining and intestinal flora detection was performed in the 3 groups respectively,meanwhile the dry and wet weight of each group rats feces and the content of water in the feces were compared.Results The intestinal flora imbalance rate of infant rats IBS group(A+B) was 70%,and there was 30% in the control group C,the difference between model group and group C was very significantly(?~2=4.34 P

In order to study the correlation between microbial diversity and the pollution degrees of the ruraldrinking water in Dongjiang River basin. Five types of drinking water of this basin were collected,and fifteen water samples of five types of drinking water of this basin had been collected from reservoir,centralized water supply wells,wells in the vicinity of pig farms,wells nearby embankment and wells in villages. The six(physical,chemical,and biological) property indices of water samples were tested,at the same time,the DGGE analysis was done. The results of PCR-DGGE fingerprint indicated that bacterial richness of these drinking water samples were high,and different samples in fingerprint were different distinctively. The UPGMA dendrogram of sample basis on DGGE fingerprints showed the structure of different types of bacteria in drinking water in rural communities is obvious differences. And the results of CCA showed that the concentration of phosphorous has the largest relevance to the community structure of bacteria in water samples,followed by the concentration of nitrogen in the water. Ten typical bands were excised and sequenced. The sequences obtained were affiliated with Spirochaetes,Cyanobacteria,Proteobacteria,Actinobacteria,Acidobacteria.

RIG-I-like receptors (RLRs) belong to pattern recognition receptors, which perform significant roles in antiviral responses. RLRs can initiate a cascade of signaling transduction that induces the production of type I interferon and activates the interferon signaling pathway, ultimately resulting in antiviral responses. In the course of evolution, viruses have been constantly counteracting host immune systems to facilitate their own survival and replication, and have developed a set of antagonistic strategies. These mainly comprise elusion, disguise and attack strategies to eliminate the activation of RLRs. In virus-infected cells, RLRs recognize viral RNA and then induce antiviral responses. A better understanding of viral antagonistic strategies against RLRs will provide insights into the development of new antiviral medicines. This mini-review concludes that there are three main antagonistic strategies by which RNA viruses can counteract the activation of the RLRs pathway. It aims to provide references and insights for similar studies on viral antagonism in an array of RNA viruses.

Objective To explore whether endothelial progenitor cells (EPCs) exerts therapeutic effects on rats with diabetic peripheral neuropathy (DPN).Methods Diabetes was induced by streptozotocin.Male SD rats were divided into normal control group(NC group), diabetic peripheral neuropathy group(DPN group), DPN+saline group(DPN+S group), and DPN+EPCs group.Sciatic nerve motor nerve conduction velocity(MNCV) was measured by a electromyography and trigger potentiometer instrument.Pathological changes were observed under optical microscope and electron microscope.Results Compared with normal control group [(52.91 ± 4.53) m/s], both DPN group and DPN+S group had slower sciatic nerve MNCV [(36.51 ± 6.30 and 25.37 ± 5.48) m/s, P＜0.01].Compared with DPN group, the MNCV of sciatic nerve in DPN + EPCs group had improved significantly [(36.51 ± 6.30 vs 46.20 ± 11.70) m/s, P ＜ 0.01].Sciatic nerve pathological changes, characterized by demyelination and axonal degeneration under light microscope and electron microscope were observed in DPN group, DPN+EPCs group, and DPN+S group.Compared with DPN+S group, the sciatic nerve pathological changes of DPN+EPCs group were alleviated.Conclusion After fed for 12 weeks, diabetic rats could progress to DPN rats.Transplantation of EPCs could improve MNCV, demyelination and axonal degeneration changes of sciatic nerver of the DPN rats.

Pulmonary fibrosis is a common respiratory disease in the clinic. Until now, the pathogenesis is still un-clear. Using clotting mechanism as the starting point, this article mainly explored abnormal changes of the coagula-tion - fibrinolysis system in the development of pulmonary fibrosis. The effective treatment through the activation of blood circulation to remove stasis in traditional Chinese medicine (TCM) point of view was also observed on the man-agement of interstitial pulmonary fibrosis. It considered that to carry out the anticoagulant therapy for abnormal coag-ulation, which may become a new target for clinical treatment of interstitial lung diseases. It provided new ideas and theoretical support for clinical treatment of pulmonary interstitial fibrosis.

To examine the effects of heterologous expression of ZrGPD1 (encoding glycerol 3-phosphate dehydrogenase ) cloned from osmotolerant yeast Zygosacharomyces rouxii on glycerol production in wild Pichia farinosa,the URA3 gene was amplified from P. farinosa as the homology integrative region. A recombinant plasmid (pUR-ZG) was constructed then transformed into P. farinosa by electroporation. The transformant pfa-gu was obtained by the selectable marker Zeocin TM . Primary results showed that the biomass of pfa-gu was higher than the wild type in the flask and after 72h fermentation the concentration of glycerol of pfa-gu was 37g/L enhanced 30% in comparison with the wild type. It is concluded that heterologous expression of ZrGPD1 is useful for increasing glycerol production and the ability of osmoregulation in P. farinosa.
