The present study intended to investigate the effect of fluvastatin on cardiomyocyte apoptosis after myocardial infarction in rats. Eighty myocardial infarction rat models were established and randomly divided into 4 groups (n=20): experimental group (n=20) was given fluvastatin treatment; sham operation group (n=20) and normal control group (n=20) were given saline. The dose of fluvastatin was 20 mg/(kg·d), and irrigation gavage was given for 1 week. Western blot analysis and reverse transcription-quantitative PCR (RT-qPCR) were used to detect the expression of TLR4 mRNA and protein in cardiomyocytes. TUNEL method was used to detect the apoptosis of cardiomyocytes. After fluvastatin treatment for 1 week, RT-qPCR found that compared with myocardial infarction group, the TLR4 mRNA expression of fluvastatin treatment group and normal control group was significantly increased, and the differences between groups were a statistically significant difference (P<0.05). Western blot analysis showed that compared with the myocardial infarction group, the expression of TLR4 protein in normal control group, sham operation group and fluvastatin treatment group were significantly decreased, and they all were statistically significant (P<0.05). TUNEL method found that compared with the myocardial infarction group, the fluvastatin treatment group could significantly reduce the apoptosis of cardiomyocytes (19.2±3.8%), and the difference was statistically significant (P<0.05). Fluvastatin can inhibit myocardial infarction and decrease cardiomyocyte apoptosis by increasing the expression of TLR4-like receptor.
Background: To explore the effect of different doses of Gamma Globulin (GG) on the condition of children with Hemolytic Disease of Newborn (HDN) and the influence of immune factors in serum. Methods: Overall, 180 infants with hemolytic disease of newborn in the People’s Hospital of Zhangqiu Area, Jinan, China from April 2016 to August 2018 were divided into group A (88 cases) and group B (92 cases). Group A was given intravenous low-dose GG on the basis of phototherapy, and group B was given intravenous high-dose GG on the basis of phototherapy. The level of serum total bilirubin of the infants, the levels of CD3+, CD4+, CD8+, IgA, IgG and IgM of the infants, the time of jaundice disappearance and the length of hospital stay, hemoglobin and reticulocyte levels were recorded before treatment and after treatment. The number and condition of adverse reactions were recorded. Results: After treatment, the levels of TBiL, hemoglobin and reticulocyte, the time of jaundice disappearance and hospital stay in group B were significantly lower than those in group A. The level of immune cells in group B was significantly higher than that in group A after 7 days of treatment, and the levels of IgA / IgG / IgM in group B were significantly higher than those in group A after 28 days of treatment. Conclusion: Intravenous high-dose GG has a better effect on the condition of neonatal hemolytic disease patients, and more effectively improve the immune function of children.
