RESUMO
Background: With the improvement of living standards in recent years, people are paying increasing attention to neonatal jaundice. Yinzhihuang granule is a common Chinese herbal drug for the treatment of neonatal jaundice. The aim of this paper was to study the efficacy of acupressure-assisted Yinzhihuang granule in the treatment of neonatal jaundice by meta-analysis. Methods: We performed a search in the databases of PubMed, Embase, Cochrane Library, Chinese Journal Full-text Database (CNKI), VIP, Wanfang Science and Technology Journal Full-text Database, and Chinese Biomedical Literature Search Database (CBM) for articles on the therapeutic effect of acupressure-assisted Yinzhihuang granule on neonatal jaundice from database establishment to October 2021. The software Endnote X9 was used to check and eliminate the articles, screen the articles according to the required inclusion and exclusion criteria, extract the data, and perform quality evaluation according to the risk of bias tool of Cochrane Collaboration. The software Stata 15.1 and RevMan 5.3 were used to record the data, and a meta-analysis was performed on the effective rate of acupressure-assisted Yinzhihuang granule in the treatment of neonatal jaundice, according to serum total bilirubin values after treatment and duration of jaundice. And show the efficacy of Yinzhihuang particles through these results. The reliability of the results was assessed by sensitivity analysis. Funnel plots were used to test the publication bias of the articles. Results: A total of 3 articles were included. The results of meta-analysis showed that when acupressure-assisted Yinzhihuang granule was used to treat neonatal jaundice, the effective rate of the test group was not significantly different from that in the control group; the serum total bilirubin level in the test group was significantly lower than that in the control group after treatment; the duration of jaundice in the test group was significantly shorter than that in the control group. Discussion: Acupressure combined with Yinzhihuang granule is effective in treating neonatal jaundice, which has a positive effect on reducing the level of serum total bilirubin and reducing the duration of jaundice.
RESUMO
OBJECTIVE: To study the effect of Bifidobacterium on the expression of ß-defensin-2 (BD-2) in intestinal tissue of neonatal rats with necrotizing enterocolitis (NEC). METHODS: A total of 40 rats were randomly divided into four groups: normal control, Bifidobacterium control, NEC model, and Bifidobacterium treatment, with 10 rats in each group. A rat model of NEC was induced by hypoxia, cold stimulation, and artificial feeding. The rats in the Bifidobacterium control and Bifidobacterium treatment groups were given Bifidobacterium via the gastric tube after cold stimulation once a day for three consecutive days. The morphological changes of the terminal ileum were observed under a light microscope and the intestinal injury score was determined. Immunohistochemistry and qRT-PCR were used to measure the protein and mRNA expression of BD-2 in the ileal mucosal tissue. RESULTS: The NEC model group had a significantly higher intestinal injury score than the normal control, Bifidobacterium control, and Bifidobacterium treatment groups (P<0.05). The Bifidobacterium treatment group had a significantly higher intestinal injury score than the normal control and Bifidobacterium control groups (P<0.05). The mRNA and protein expression of BD-2 in the normal control group was significantly lower than in the Bifidobacterium control, NEC model, and Bifidobacterium treatment groups (P<0.05). The Bifidobacterium control group had significantly higher mRNA and protein expression of BD-2 than the NEC model and Bifidobacterium treatment groups (P<0.05). The Bifidobacterium treatment group had significantly higher mRNA and protein expression of BD-2 than the NEC model group (P<0.05). CONCLUSIONS: Bifidobacterium can induce the expression of BD-2 in intestinal tissue of rats and reduce inflammatory response by increasing the expression of BD-2. This provides a protective effect on neonatal rats with NEC.
