ABSTRACT

Objective:To investigate the efficacy of Xiaoer Jinqiao granule combined with interferon α-2b on acute herpangina in children and its effect on immune function and myocardial enzyme. Methods:A total of 102 children with acute herpangina who received treatment in Hangzhou Ninth People's Hospital from January 2019 to January 2020 were randomly assigned to receive treatment with either interferon α-2b (control group, n = 51) or Xiaoer Jinqiao granule combined with interferon α-2b (observation group, n = 51) for 5 d. The time to disappearance of main symptoms, changes in humoral immune function, changes in cellular immune function and myocardial enzyme level after treatment relative to before treatment as well as curative effect were compared between the control and observation groups. Results:The time to disappearance of pharyngeal herpes [(3.05 ± 0.74) d], salivation [(2.31 ± 0.68) d], and fever [(1.36 ± 0.39) d] in the observation group were significantly shorter than those in the control group [(4.38 ± 0.98) d, (3.83 ± 1.07) d, (2.54 ± 0.71) d, t = 7.773, 8.562, 10.403, all P < 0.05]. After treatment, serum IgA [(1.49 ± 0.16) g/L], IgG [(10.29 ± 0.89) g/L] and IgM [(1.26 ± 0.14) g/L] levels in the observation group were significantly higher than those in the control group [(1.13 ± 0.12) g/L, (9.35 ± 0.72) g/L and (0.98 ± 0.13) g/L, t = 12.855, 5.864 and 10.466, all P < 0.05]. After treatment, CD 3+ [(74.29 ± 2.15)%], CD 4+ [(40.85 ± 1.65)%] and CD 4+/CD 8+ expression [(1.87 ± 0.23)] in the observation group were significantly higher than those in the control group [(67.96 ± 2.43)%, (38.02 ± 1.20)% and (1.49 ± 0.14), t = 13.933, 9.906 and 10.079, all P < 0.05]. After treatment, serum creatine kinase [(147.86 ± 15.42) U/L] and lactate dehydrogenase [(128.64 ± 14.25) U/L] in the observation group were significantly lower than those in the control group [(176.95 ± 13.15) U/L and (184.32 ± 18.98) U/L, t = 10.251, 16.754, both P < 0.05]. Total effective rate in the observation group was significantly higher than that in the control group [92.16% (47/51) vs. 74.51% (38/51), χ 2 = 5.718, P < 0.05]. Conclusion:Xiaoer Jinqiao granule combined with interferon α-2b has obvious curative effect on acute herpangina in children because it can improve the humoral and cellular immune function and reduce myocardial damage.
