The small RNA PrrH of Pseudomonas aeruginosa regulates hemolysis and oxidative resistance in bloodstream infection.

Small regulatory RNAs (sRNAs) regulate multiple physiological functions in bacteria, and sRNA PrrH can regulate iron homeostasis and virulence. However, the function of PrrH in Pseudomonas aeruginosa (P. aeruginosa) bloodstream infection (BSI) is largely unknown.

[Research on Glycyrrhizeae Radix standard decoction].

Fifteen batches of Glycyrrhizeae Radix standard decoction were prepared for determination of the content of the glycyrrhizic acid and liquiritin, then the transfer rate and the extract rate were calculated and a method was established to analyze the fingerprint by HPLC. According to the measurement of 15 batches of samples,the transfer rate of the glycyrrhizic acid and liquiritin were 59.4%-87.
