MicroRNAs(miRNAs) are endogenous non-coding RNAs,about 20 nucleotides in length.They play a pivotal role in the regulation of genes involved in diverse biology processes such as cell development,proliferation,differentiation and apoptosis by the translation repression or mRNA degradation.Recent evidence has suggested that miRNA alterations are involved in the initiation and progression of various human cancer including hepatocellular carcinoma(HCC),and miRNA-expression profiling of HCC has identified signatures associated with diagnosis,staging,progression and prognosis.As a novel molecular target,miRNAs holds great promise in diagnosis and biotherapy of HCC.

Circulating nucleic acids (CNAs) are extracellular nucleic acids found in cell-free serum,plasma and other body fluids from healthy subjects as well as in patients. The ability to detect and quantitate specific DNA and RNA sequences has opened up the possibility of diagnosis and monitoring of diseases,especially in the field of cancer. Furthermore,in some recent studies it has been suggested a kind of non-coding RNA-microRNA (miRNA),also exist in cell-free serum and plasma,highlighting the field of using CNAs to diagnose cancer. As a novel tumor marker,tumor-specific circulating miRNAs holds great promise in early diagnosis of cancer.

Hepatocellular carcinoma(HCC),one of the most common malignant tumors,is the main cause of cancer death in China.Early diagnosis of the disease is of great importance.Serum tumor markers have been effective for detecting HCC for a long time.Among those markers,alpha fetoprotein(AFP)is the most widely used one in detecting patients with HCC,but it has limited utility for detecting HCC due to its limited sensitivity and specificity.Searching better markers for HCC has been a re- search focus in recent years.This review introduces many useful markers to supplement AFP for detecting HCC.

Objective To analyze the correlation of gamma-glutamyl transpeptidase (GGT)level with alpha-fetoprotein (AFP)level and to re-evaluate the diagnostic value of GGT for hepatocellular carcinoma (HCC).Methods Four hundred and seventy-two patients with HCC or liver cirrhosis,who were hospitalized in China-Japan Friendship Hospital from January 2003 to June 2009,were included in the study.The correlation between GGT and AFP was analyzed by Spearman nonparametric test.The cut-off values for the two parameters were determined based on their receiver operating characteristics (ROC)curves,areas under the ROC curve (AUCs),sensitivity,and specifici-ty,and the diagnostic values were presented using their sensitivity,specificity,and correct index.Statistical analysis was performed using SPSS 17.0.Normally distributed continuous data were analyzed by independent-samples t test,while non-normally distributed continuous data were analyzed by Mann -Whitney U test.Categorical data were analyzed by Pearson chi -square test,continuity-corrected chi -square test,or Fisher’s exact test.Results Among 472 patients,224 were diagnosed with HCC,and 248 with liver cirrhosis.Compared with cirrhotic patients,HCC patients had a significantly higher GGT level (113 (58-254)U/L vs 38 (22-72)U/L,Z=-11.037,P<0.001)and a significantly higher AFP level (429.5 (15.7-1210.0)ng/ml vs 5.7 (3.4-18.2)ng/ml,Z=-10.157,P<0.001).A significant correlation was found between GGT and AFP (r=0.449,P<0.001).The AUC was 0.784 for GGT and 0.788 for AFP.The cut-off value was 60 U/L for GGT and 20 ng/ml for AFP.The sensitivity was 74.1%for GGT,71.8%for AFP,and 90.7%for a combina-tion of the two parameters,the specificity was 70.2%,77.6%,and 58.7%,respectively,and the correct index was 0.443,0.494,and 0.494,respectively.Conclusion GGT may be regarded as one biomarker for HCC,and its level is significantly correlated with AFP level. The diagnostic value of AFP may not be improved when used in combination with GGT.

Pa disease is often caused by the invasion of wind,cold,moist and heat.Its symptoms usually are pain,numbness,tumescence,muscle and vessel contracture,unfavourable ection and stretch,arthrentasis,function disuse and so on.Its clinical characteristics are chronicity,recurrent attacks and aggravating little by little.Its mutilation rate is high,and it hurts the patients physically and mentally.The clinical treating method should be based on di erentiation of syndrome and di erentiation of disease.Selecting Chinese materia medica reasonably will conduce to satisfactory curative e ect.

Objective: To provide foundation for clinical application through studying the drug action and mechanism of action of Lingdantongfengkang Capsule on anti-gout effects. Methods: Lingdantongfengkang Capsule was taken orally. The experimental methods were as follow: mouse ear swell induced by dimethylbenzene, mouse pain induced by injecting acidum aceticum in abdominal cavity, mouse hyperuricemia model induced by yeast. Results: Lingdantongfengkang Capsule could lessen mouse ear swell induced by dimethylbenzene, decreae mouse stretching frequencies induced by injecting acidum aceticum in abdominal cavity and antagonize animal serum uric acid,liveness of xanthinoxidase and urea nitrogen induced by yeast to mice.Conclusion: Lingdantongfengkang Capsule possesses the anti-gout effects.
