Objective: To explore the clinical effects of Lanqin oral liquid in the treatment of pediatric herpangina and its effects on serum inflammatory factors. Methods: A total of 120 cases with pediatric herpangina admitted into our hospital from Mar. 2015 to Mar. 2018 were extracted to be divided into the observation group and the control group via the random number table

with 60 cases in each group. The control group was given Kaihoujian spray and symptomatic treatment

while the observation group received Lanqin oral liquid on the basis of the control group. The clinical efficacy and adverse drug reactions of two groups were compared

the serum interleukin-2 (IL-2) and tumor necrosis factor-a (TNF-a) levels were measured in two groups before and after treatment. Results: After treatment

the antipyretic time and disappearance time of herpes and ulcer in the observation group was shorter than that in the control group

and the difference was statistically significant (P<0.05). There were four cases of adverse drug reactions in the observation group and 5 cases in the control group

with no statistically significant difference (P>0.05). After treatment

the levels of IL-2 in two groups were higher than that before treatment and TNF-a was lower than that before treatment

the difference was statistically significant (P<0.05). After treatment

the levels of IL-2 in the observation group was higher than that in the control group

and the levels of TNF-a was lower than that in the control group

with statistically significant differences (P<0.05). Conclusion: The clinical efficacy of Lanqin oral liquid in the treatment of pediatric herpangina is significant

which can effectively reduce the inflammatory response in children.
