Altered lymphocyte counts in a pediatric patient with H5N1 infection.

Flow cytometry was used to analyze the changes in lymphocyte subsets in the youngest child with avian influenza in China. During the early stage, the absolute CD3 count was 62.9% (lower limit of normal), the CD8 count was 32.5% (slightly higher than normal), and the CD4 count was 28.6% (lower than normal). The CD4/CD8 ratio was also decreased (0.88). The natural killer (CD3CD1656) cell count was 4.9% (lower than normal). During the convalescent stage, the CD4 count and the CD4/CD8 ratio returned to normal. The CD3CD1656 count increased from its value at the early stage of the disease.

Effect of lactated Ringer's solution and compound electrolyte solution on the corneal endothelium in phacoemulsification / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To compare the effect of compound electrolyte solution and lactated Ringer's solution on corneal function in cataract phacoemulsification,and to provide scientific basis for clinical selection of appropriate perfusion fluid.METHODS:The patients with senile cataract were randomly divided into control group with lactated Ringer's solution as anterior chamber perfusion and experimental group with compound electrolyte as anterior chamber perfusion.Surgical removal of cataract and phacoemulsification with intraocular lens implantation were taken.The corneal endothelial cell density,central corneal thickness,hexagonal cell ratio and endothelial cell coefficient of variation were measured at preoperative and postoperative points.RESULTS:Totally 60 patients successfully completed all follow-ups,the experimental group of 30 cases,the control group of 30 cases.The density of corneal endothelial cells in experimental group was significantly higher than those in the lactated Ringer's solution group at 1 and 3d after operations (P=0.030,0.046).The coefficient of variation of corneal endothelial cells in lactated Ringer's solution group was higher than that in compound electrolyte group at 1 and 14d after operation (P=0.025,0.014).The visual acuity of the compound electrolyte group was better than that of the lactated Ringer's solution on the first day after operation (P=0.04).CONCLUSION:In the phacoemulsification of senile cataract,the compound electrolyte perfusion has better histocompatibility,which can maintain the stability of corneal endothelial cell structure and reduce corneal endothelial cell injury.The compound electrolyte perfusion solution is more suitable for senile cataract phacoemulsification surgery.
