Effect of breastfeeding on immune function in infants with human cytomegalovirus infection / 中国当代儿科杂志

OBJECTIVES@#To study the effect of breastfeeding on immune function in infants with human cytomegalovirus (HCMV) infection.@*METHODS@#A retrospective analysis was performed on the medical data of 135 infants with HCMV infection who were admitted to Children's Hospital Affiliated to Zhengzhou University from January 2021 to May 2022, and all these infants received breastfeeding. According to the results of breast milk HCMV-DNA testing, the infants were divided into two groups: breast milk HCMV positive (n=78) and breast milk HCMV negative (n=57). According to the median breast milk HCMV-DNA load, the infants in the breast milk HCMV positive group were further divided into two subgroups: high viral load and low viral load (n=39 each). Related indicators were compared between the breast milk positive and negative HCMV groups and between the breast milk high viral load and low viral load subgroups, including the percentages of peripheral blood lymphocyte subsets (CD3+ T cells, CD3+CD4+ T cells, CD3+CD8+ T cells, and CD19+ B cells), CD4+/CD8+ ratio, IgG, IgM, IgA, and urine HCMV-DNA load.@*RESULTS@#There were no significant differences in the percentages of CD3+ T cells, CD3+CD4+ T cells, CD3+CD8+ T cells, and CD19+ B cells, CD4+/CD8+ ratio, IgG, IgM, IgA, and urine HCMV-DNA load between the breast milk HCMV positive and HCMV negative groups, as well as between the breast milk high viral load and low viral load subgroups (P>0.05).@*CONCLUSIONS@#Breastfeeding with HCMV does not affect the immune function of infants with HCMV infection.

Effect of Local Intramuscular Repeated Injection with Botulinum Toxin-A for Treatment of Spastic Cerebral Palsy / 实用儿科临床杂志

Objective To observe the curative effect of botulinum toxin A(BTX-A)repeated intramuscular injection for treatment of serious spastic cerebral palsy.Methods Thirty cases with serious spastic cerebral palsy received local repeated intramuscular injection. The interval time was 3 months. The dose of BTX-A was 4 U/kg.The muscle tone was assessed with the modified ashworth scale and range of motion with physical rating scale(PRS).The indexes were evaluated before injection and 3 months after the second injection. Paired-samples t-test was used in the statistic analysis.Result The muscle tone and PRS had remarkable improvement after second therapy with BTX-A(P

Studies on the effect of dihydromyricetin on antilipid-peroxidation / 中国中药杂志

<p><b>OBJECTIVE</b>To study the effects of Dihydromyricetin (DMY) on antilipid-peroxidation.</p><p><b>METHOD</b>The antilipid-peroxidation of DMY on heart, liver, brain tissue homogenate and mitochondria was measured by the determination of malondiadehyde (MDA) induced by Fe2+ -Vit C, Fe2+ -H2O2, Fe-Cys with TBA spectrometric method.</p><p><b>RESULT</b>DMY could inhibit the lipid peroxidation of homogenate and mitochondria. The inhibition exhibited concentration-dependent manner.</p><p><b>CONCLUSION</b>DMY has good antilipid-peroxidation effect, which is worth studing further.</p>
