Hepatitis C virus (HCV)infection is one of the most common causes of chronic hepatitis,liver cirrhosis,and hepatocellular car-cinoma.MicroRNAs (miRNAs),a class of small,non -coding RNA,are involved in a variety of physiological and pathological processes in human bodies.The mechanism by which miRNAs regulate HCV replication is described,and the effects of liver -specific microRNA -122 antagonists on hepatitis C antiviral therapy are discussed.Our study indicates that miRNAs play an important regulatory role in HCV ex-pression.Targeting miRNAs may be a potential therapeutic approach for treating HCV infection,but further studies are still in need.

Objective To explore the relationship between the risk of amyotrophic lateral sclerosis (ALS) and exposure to rural environments and pesticide.Methods Studies relevant to rural residence,farmer occupation,pesticide exposure and ALS were identified from the databases including Embase,Ovid Medline,Pubmed,Cochrane Library,Wanfang data,Chinese BioMedical Literature Database,Chinese National Knowledge Infrastructure,China Science and Technology Journal Database up to March 2015.Quality of studies was assessed according to the Newcastle-Ottawa Scale (NOS).Analysis of data and publication bias was performed with software Revman 5.3.Results A total of 24 case-control studies and 3 cohort studies were included into the analysis.The NOS scores of all studies were ≥6.The risk of ALS was associated with pesticide exposure (OR =1.41,95％ CI 1.28-1.56) and farmer occupation (OR =1.42,95％ CI 1.29-1.57),but not associated with rural residence (OR =1.21,95％ CI 0.97-1.51).Subgroup analysis of pesticide exposure and ALS revealed that males (OR =1.75,95％ CI 1.39-2.21) had a higher risk than females (OR =1.53,95％ CI 1.13-2.08),and the risk estimate was higher in studies using E1 Escorial standard (OR =1.68,95％ CI 1.45-1.95) than studies not (OR =1.23,95％ CI 1.08-1.40).The meta analysis had a slight publication bias.Conclusions Our findings support pesticide exposure might increase the risk of ALS.Given that farmers always have high levels of pesticide exposure in their work,they should decrease their exposure level or take proper precautions to lower the risk of ALS.
