ABSTRACT

Objective:To explore the effect of bifidobacterium tetravaccine tablets combined with low-dose erythromycin on the efficacy and motilin (MTL) levels in the treatment of children with functional dyspepsia (FD).Methods:One hundred and fifty children with FD admitted to Shanghai Public Health Clinical Center from January 2019 to June 2020 were selected and were divided into two groups by random number table, with 75 cases in each group. The control group was treated with bifidobacterium tetravaccine tablets, and the observation group was treated with low-dose erythromycin on the basis of control group. The clinical efficacy and the disappearance time of the clinical symptoms of the two groups were compared. The changes in the frequency of gastric antrum contraction (ACF), the amplitude of gastric antrum contraction (ACA), the gastric antral movement index (MI) were detected by ultrasonic developing-out unit before and after treatment. The levels of 5-hydroxytryptamine (5-HT), nitric oxide (NO), gastrin (GAS) and MTL were detected before and after the treatment using enzyme linked immunosorbent assay. The incidence of adverse reactions was counted. The recurrence rate was recorded after 6 months of the treatment.Results:The total effective rate in the observation group was higher than that in the control group93.33% (70/75) vs. 78.67% (59/75), and the difference was statistically significant ( χ2 = 6.700, P<0.05). The disappearance time of symptoms of nausea and vomiting, loss of appetite, abdominal distension, and abdominal pain in the observation group were shorter than those in the control group (2.58 ± 0.45) d vs. (3.22 ± 0.68) d, (3.56 ± 0.62) d vs. (4.10 ± 0.70) d, (2.54 ± 0.46) d vs. (3.24 ± 0.69) d, (2.66 ± 0.56) d vs. (3.40 ± 0.67) d, and the differences were statistically significant ( P<0.05). The levels of ACF, ACA and MI in the observation group after the treatment were higher than those in the control group (4.32 ± 0.90) times/min vs. (3.58 ± 0.83) times/min, (0.34 ± 0.12) vs. (0.30 ± 0.10) mm, (1.33 ± 0.42) vs. (1.14 ± 0.30), and the differences were statistically significant ( P<0.05). The levels of 5-HT and NO in the observation group after the treatment were lower than those in the control group (164.77 ± 30.34) mg/L vs. (184.45 ± 28.90) mg/L, (38.27 ± 10.20) mmol/L vs. (46.54 ± 9.48) mmol/L; and the levels of GAS and MTL were higher than those in the control group (115.23 ± 15.70) ng/L vs. (98.50 ± 14.29) ng/L, (266.67 ± 32.76) ng/L vs. (238.40 ± 28.97) ng/L, and the differences were statistically significant ( P<0.05). Conclusions:The treatment of pediatric FD with bifidobacterium tetravaccine tablets combined with low-dose erythromycin can significantly improve the efficacy, quickly improve the clinical symptoms of children, promote physical recovery, and regulate MTL levels to improve gastric motility. The recurrence rate is low.
