Methods A total of 452 patients with common HFMD were randomly assigned to receive Western medicine alone (n=220) or combined with TCM (Reduning or Xiyanping injections) (n=232). The primary outcome was the incidence rate of rash/herpes disappearance within 5 days, while secondary outcomes included the incidence rate for fever, cough, lethargy, agitation, and vomiting clearance within 5 days. Results The rash/herpes disappearance rate was 45.5% (100/220) in Western medicine therapy group, and 67.2% (156/232) in TCM and Western medicine combined therapy group, with significant difference (P<0.001). Moreover, TCM remarkably increased the incidence rate of secondary disappearance, which was 56.4%in Western medicine therapy group and 71.4%in TCM and Western medicine combined therapy group (P=0.001). No drug-related adverse events were observed. Conclusions It’s suggested that the integrative TCM and Western medicine therapy achieved a better therapeutic efficacy. TCM may become an important complementary therapy on relieving the symptoms of HFMD.展开更多

文摘Enterovirus 71(EV71)infection is more likely to cause hand,foot and mouth disease(HFMD)in children,which can lead to neurogenic complications and higher mortality.As a commonly used clinical medicine,Reduning injection(RDN)helps to shorten the symptoms of patients with HFMD and facilitate the early recovery of children.However,the regulatory mechanism of RDN on the HFMD immune system disorder caused by EV71 remains to be discussed.This study collected detailed treatment data of56 children with HFMD who entered the affiliated Children’s Hospital of Nanjing Medical University during 2019.Retrospective analysis of clinical data showed that the symptoms of the RDN treatment group were improved compared with the untreated group.To explore its mechanism,the relevant detection indicators were detected by flow cytometry,enzyme-linked immunosorbent assay and realtime quantitative PCR.It was found that the number and function of innate immune(ILCs)and adaptive immunity(Th1,Th2 and secreted cytokines)were reduced,suggesting that RDN plays a role by regulating cellular immunity.The in vitro differentiation inhibition test further confirmed that RDN affected Th1 differentiation by inhibiting the expression of transcription factors on the basis of Th1 cell differentiation in vitro.
