ABSTRACT
Objective To explore the effects of operative time on the prognosis in patients with complicated ocular trauma undergoing vitrectomy.Methods Clinical data of 120 patients (128 eyes) with complicated ocular trauma from May 2012 to May 2017 in our hospital were retrospectively analyzed.Then all the subjects were divided into five groups according to the different operative time of vitrectomy,and the functioncure rate was compared in the 5 groups.Results There were 6 patients (6 eyes) receiving operation on day 0 to 5 after the injury,and the functional cure rate was 66.67％,48 patient (50 eyes) receiving operation on day 6 to 10 after the injury,followed by 32 patients (34 eyes) being functional cured with the curative rate of 68.00％,30 patient (34 eyes) receiving operation on day 11 to 15 after the injury,followed by 24patients (26 eyes) being functionally cured with the curative rate of 76.47％,18 patient (20 eyes) receiving operation on day 16 to 20 after the injury,followed by 8 patients (8eyes) being functionally cured with the curative rate of 40.00％,10 patient (10 eyes)receiving operation on day 21 to 25 after the injury,followed by 2 patients (2 eyes) being functionally cured with the curative rate of 20.00％,8 patient (8 eyes) receiving operationover 25 days after the injury,followed by 2 patients (2 eyes) being functional cured with the curative rate of 25.00％,which suggested that patients suffered the injury with 11 days to 15 days had the highest function-cure rate (all P ＜0.05).Conclusion The operative time does matter,which can affect the cure rate of patients with complicated ocular trauma undergoing vitrectomy,and the most suitable time of ocular trauma surgery is 11-15 days after the injury.
ABSTRACT
Natural killer (NK) cells are important innate immune effector cells with broad applications in killing the tumor cells and pathogens due to its cytotoxicity without prior immune sensitization. Unfortunately, in humans, the activity of NK cells against fungi is poorly characterized. Insight progress in the fields of NK cells activating, pattern recognition receptors, signal modulating and correlated cell factors (IFN-γ, GM-CSF, IL-10 and so on) has revolutionized understanding of the selective killing fungi by NK cells. Different morphotypes also can affect the immune status of NK cells. This article reviews the mechanism of fungi immune reaction, and the interaction between NK cells and fungi, and provides some new ideas for further study on pathogenesis of fungus and other infectious diseases and NK cell adoptively transferred immunotherapy.

Fcγ receptorIIIa (FcγRIIIa) polymorphism was considered to influence clinical response to therapeutic monoclonal antibody (MAb) against cancer, which is suggested to affect MAb binding and MAb-dependent NK cell-mediated cytotoxicity. The purpose of this study was to examine the FcγRIIIa gene polymorphisms in healthy children and in children with hematological malignancy, and to explore its possible effect on MAb in children with hematological malignancies. 43 healthy children (H) and 20 pediatric patients with hematological malignancies (HM) were enrolled in this study. DNA was isolated from peripheral blood, and then nest-polymerase chain reaction-restriction fragment length polymorphism (nest-PCR and PCR-RFLP) was used to determine the FcγRIIIa-158 genotypes in each groups of subject, digested fragments were subjected to electrophoresis on 15% PAGE. The results showed that there were a higher frequencies of FcγRIIIa-158V/F in H and HM group (72.1% and 75.0% respectively), the frequencies of FcγRIIIa-158V/V were 27.9% and 25.0% in H and HM group respectively, but there was no FcγRIIIa-158F/F in the two groups. No significant difference in distribution of the FcγRIIIa-158 genotype was found between HM and H groups (p > 0.05). It is concluded that FcγRIIIa-158V/F is more frequent, while FcγRIIIa-158V/V is less, but FcγRIIIa-158F/F is very rare in both groups. No significant difference of FcγRIIIa polymorphism distribution is found between healthy and hematological malignancy groups.
