Statins can bring some benefits to the treatment of diabetic cardiomyopathy (DCM), but the specific molecular pathway of their action is still unclear. Recent studies have shown that abnormal expression of long noncoding RNA (lncRNA) is closely related to the pathological development of DCM. To compare the degree of myocardial injury between diabetic rats treated with rosuvastatin and rats treated with conventional therapy, the therapeutic pathway and potential target of rosuvastatin on DCM was investigated. Total RNA of DCM rats was extracted and 1ncRNA microarray was prepared to screen out differentially expressed 1ncRNA and bioinformatics analysis was carried out. The results showed that 770 target genes were up-regulated and 884 were down-regulated in the treatment group compared with the model group, which were mainly related to improvement of metabolic disorder, regulation of the ratio of myocardial cells to collagen fibers, reduction of myocardial injury and exercise burden, prevention of autonomic nervous system and microcirculation diseases and change of eating habits. The signaling pathways involved are mainly concentrated in sensory pathways, signal transduction, lipid metabolism and so on. It is suggested that rosuvastatin may play a role in the treatment of DCM by regulating the participation of 1ncRNA in glucose and lipid energy metabolism and ion balance, inhibiting the process of myocardial fibrosis and improving the effect of high glucose toxicity on autonomic nervous function.

Objective:
Moxifloxacin (MFX) shows good activity against and can be a possible antibiotic therapy to treat infection; however, other studies have shown a lower or no activity. We aimed to evaluate MFX activity against using zebrafish (ZF) model .
Methods:
A formulation of labeled with CM-Dil was micro-injected into ZF. Survival curves were determined by recording dead ZF every day. ZF were lysed, and colony-forming units (CFUs) were enumerated. Bacteria dissemination and fluorescence intensity in ZF were analyzed. Inhibition rates of MFX and azithromycin (AZM, positive control) were determined and compared.
Results:
Significantly increased survival rate was observed with different AZM concentrations. However, increasing MFX concentration did not result in a significant decrease in ZF survival curve. No significant differences in bacterial burdens by CFU loads were observed between AZM and MFX groups at various concentrations. Bacterial fluorescence intensity in ZF was significantly correlated with AZM concentration. However, with increasing MFX concentration, fluorescence intensity decreased slightly when observed under fluorescence microscope. Transferring rates at various concentrations were comparable between the MFX and AZM groups, with no significant difference.
Conclusion
MFX showed limited efficacy against using ZF model. Its activity needs to be confirmed.
