An exploration of the value of NLR, PLR, LMR, and WBC × CRP for the diagnosis and treatment of influenza B in adults.

The aim of the study was to study the diagnostic and therapeutic utility of NLR (neutrophil-to-lymphocyte ratio), LWR (lymphocyte-to-monocyte ratio), PLR (platelet-to-lymphocyte ratio), and WBC × CRP (WBC: white cell count, CRP: C-reactive protein) in patients with influenza B. This retrospective study included 122 adult patients with influenza B, 176 adult patients with bacterial infection, and 119 adult healthy physical examinees for routine blood examination and CRP testing, calculation of NLR, LMR, PLR, and WBC × CRP for relevant statistical analysis, monitoring of NLR, LMR, PLR and WBC × CRP in patients with influenza B during relevant treatment. All indicators, except for WBC and NLR, had no statistical differences between the influenza B group, the normal control group, and the influenza B group and bacterial infection group, respectively, and showed no statistical significance for the differences between the groups.

Short-day signals are crucial for the induction of anthocyanin biosynthesis in Begonia semperflorens under low temperature condition.

The leaves of Begonia semperflorens accumulate anthocyanins and turn red in autumn in sub-temperate areas. This induction of anthocyanin biosynthesis in autumn has been attributed to the effects of low temperature, but the effects of different light regimes on this process are still being debated. In the present work, short days were found to be necessary for anthocyanin biosynthesis at low temperature.
