ABSTRACT
Viral myocarditis (VMC) is a disease characterized by inflammation of myocardial cells caused by viral infection. Since the pathogenesis mechanism of VMC has not been fully elucidated, the diagnosis and treatment of this disease remains extremely challenging. Non-coding RNAs (ncRNAs) are a class of RNAs that do not encode proteins. An increasing number of studies have shown that ncRNAs are involved in regulating the occurrence and development of VMC, thus providing potential new targets for the treatment and diagnosis of VMC. This review summarizes the possible roles of ncRNAs in the pathogenesis and diagnosis of VMC revealed recently.

Enterovirus 71 (EV71) is a major pathogen causing severe hand, foot and mouth disease (HFMD) in infants under five years old. It can cause central nervous system damageand even death in severe cases. Considering the high mortality and disability rate of HFMD, this review focused on the most recent developments in vaccines and treatments against EV71 infection.
ABSTRACT
AIM: To establish a RP-HPLC method for simultaneous determination of the dl-tetrahydropalmatine and imperatorin in Yuanhu Zhitong Prescription (Rhizoma Corydalis, Radix Angelicae Dahuricae). METHODS: dl- tetrahydropalmatine and imperatorin were extracted with ether and determined by HPLC using a BDS C 18 column(5?m,4.6?250mm),phosphate buffer(pH6.6)-methanol(39∶61) as a mobile phase. The mobile rate was at 1mL?min -1 and detection wavelength was at 280nm. RESULTS: The relationship between the concentration and the peak area of dl-tetrahydropamaltine and imperatorin were good linear relation, respectively. Either of correlation coefficient approached 0.999. CONCLUSION: This method can be used to determine the concentration of dl-tetrahydropalmatine and imperatorin in the preparation of Yuanhu Zhitong Prescription.
