Both sides of the picornavirus genome have 5'-untranslated region (5'UTR) and 3'- untranslated region (3'UTR). This study demontrated that both the 5'-and 3'-UTR can form complex structures, such as stem-loop, clover and pseudoknot structure, These structures play an important role in the regulaton of the replication and translation of the viruses. This article reviewed the progress of research on the structure and function of picornavirus' 3'-UTR over recent years.

Inflammation plays an essential role in the pathophysiology of atherosclerosis. Our study was aimed to investigate whether salvianolate, a novel water-soluble phenolic compound of Danshen, alleviates atherosclerosis via regulating the inflammation in rats. High fat diet feeding plus vitamin D3 injection was used to induce atherosclerosis in rats. Salvianolate (60, 120 or 240 mg/kg) or placebo was given to atherosclerotic rats. The plasma lipids, interleukin 6 (IL-6) and C reactive protein (CRP) were measured by ELISA. CD4+CD25+Foxp3+ cells were determined by flow cytometry. Histological changes were examined by hematoxylin and eosin staining. The results showed that the levels of plasma IL-6 and CRP were elevated in the rats fed on high fat diet, and the histological analysis demonstrated the successful establishment of atherosclerosis models. Treatment with salvianolate alleviated the atherosclerotic process and decreased the levels of plasma IL-6 and CRP. Also the number of CD4+CD25+Foxp3+ cells was increased in salvianolate-treated rats. It was concluded that salvianolate could treat atherosclerosis via modulating the inflammation at cytokine and cell levels.

Objective To evaluate the clinical application and safety of CT-guided pereutaneous transthoracic biopsy in the diagnosis of mediastinal masses.Methods Thirty three cases were undertaken CT- guided percutaneous transthoraeie biopsy with automatic biopsy gun and then the sampling specimens were undergone histological examination.The accuracy of puncture,diagnostic correctness and complications were analyzed.Results The operations were performed successfully in all 33 cases(100%),the definite pathologic diagnosis were made in 28 out of 33 cases(85%)and no complications occurred.Conclusion As for midiastinal masses,CT-guided percutaneous transthoracic biopsy is a feasible,successful,efficient interventional diagnostic method with high accuracy in localization,puncture,diagnosis and few complications, which should he recommended in clinical use more widely.(J Intervent Radiol,2007,16:852-854)

The culture medium and cultural conditions of solid-state fermentation of Streptomyces Menmyco-93-63 were tested in this study. The suitable medium which contains rice, sorghum, millet bran, and rice hull with the proportion of 2:2:3:3 was developed for the spore production of Streptomyces Men-myco-93-63 using single substrate screening, mixture substrate screening and orthogonal experiments, and the sporulation was up to 2.52?109 CFU/g. And then, initial charge, initial ratio of water to solid, inoculating quantity, and culture temperature impact to sporulation of Streptomyces Men-myco-93-63 were tested. The favorite cultural conditions are developed as the following: the initial charge is 15 g in 500 mL Erlenmeyer flask; initial ratio of water to solid is 1.7:1.0 (V/W, rice hull excluding), inoculating quantity is 7 mL, culture temperature is 28℃.

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 investigate the expression of the interleukin-1 receptor(IL-1R)Ⅰ,IL-1RⅡand IL-1R accessory protein(IL-1RAcP)in osteoarthritis and analyse their biological significance.Methods Immunohistochemistry and reverse transcription-polymerase chain raction(RT-PCR)were adopted to detect the expression of IL-1RⅠ,IL-1RⅡand IL-1RAcP on the synovium of 107 OA patients.Results Immunohis- tochemistry showed strong positive expression of IL-1RⅠand IL-1RAcP,and positive expression of IL-1RⅡ. The expression was distributed in lining cells,monocyts and vascular endothelial cells of the sublining area, but all of them were negative or weak positive in normal synoviums.RT-PCR showed the expression of IL-1RⅠ,IL-1RⅡand IL-1RAcP in OA synoviums was significantly enhanced than normal synoviums (P＜0.05),and the expression of IL-1RⅠwas significantly enhanced than IL-1RⅡ(P＜0.05),but no sig- nificant difference with IL-1RAcP(P＞0.05).In stageⅡandⅢOA synoviums,the expression of IL-1RⅠand IL-1 RAcP had no significant difference with normal synoviums(P＞0.05).The expression of IL-1RⅡin stageⅢOA synoviums was significantly enhanced than normal(P＜0.05).Conclusion IL-1RⅠ,IL-1RⅡand IL-1RAcP play significant roles in the pathogenesis of OA,especially IL-1RⅠand IL-1RAcP.But their increase is only observed in the early stage of OA.These suggest that they may have no association with the development of OA and have no direct association with the severity of OA.OA can be cured by interrupting the signal transduction path in which IL-1 has played biological roles.
