ABSTRACT
Objective@#To explore the effect of hydrogen-rich saline on the CD4+ CD25+ Foxp3+ Treg cells in a guinea pig model of allergic rhinitis (AR) and investigate the underling anti-inflammatory mechanism.@*Methods@#Using random number table, eighteen guinea pigs were divided into three groups (control group/AR group/HRS group, n=6 of each group). AR guinea pig model was built with ovalbumin and aluminum. The guinea pigs were injected with hydrogen-rich saline (HRS group) for ten days after sensitation. And control group was injected with equal normal saline at the same time. Number of sneezes, degree of runny nose and nasal rubbing movements were scored. Peripheral blood eosinophil count was recorded. The content of interleukin 10(IL-10) and transforming growth factor β (TGF-β) in the serum were detected by enzyme-linked immunosorbent assay (ELISA). Immunohistochemical method was taken to detect IL-10 and TGF-β in nasal mucosa. The proportion of CD4+ CD25+ Foxp3+ T cells in the CD4+ T cells of spleen and peripheral blood were determined with flow cytometry. SPSS 17.0 software was used to analyze the data.@*Results@#There was significant difference in symptom scores among them. The scores of AR group preceded control group, and HRS could decrease the scores of AR ((6.29±1.79) vs (1.01±0.71), (4.50±0.84) vs (6.29±1.79), F=24.725, all P<0.05). The highest number of eosinophils in the peripheral blood belonged to control group, and the number of eosinophils were dramatically reduced after HRS administration ((0.41±0.05)×109/L vs (0.25±0.03 )×109/L, (0.32±0.03)×109/L vs (0.41±0.05)×109/L, F=70.05, all P<0.05). The content of IL-10 and TGF-β in control group is peak ((86.88±17.17) pg/ml, (598.28±72.70) pg/ml, respectively), and compared with AR group, HRS also increased the expression of IL-10 and TGF-β of peripheral blood ((72.54±11.75) pg/ml vs (53.49±10.07) pg/ml, (530.23±57.15) pg/ml vs (482.69±65.96) pg/ml, F value was 28.357, 14.128, respectively, all P<0.05). The proportion of CD4+ CD25+ Foxp3+ Treg cells in controls exceeded HRS group and AR group (1.81%±0.10%, 1.29%±0.74%, respectively), and HRS treatment increased the ratio of CD4+ CD25+ Foxp3+ Treg cells than AR group of peripheral blood ((1.50%±0.11%) vs (1.15%±0.11%), F=168.96, P<0.05). But there was no significant diferences in splene tissue ((1.01%±0.08%) vs (0.98%±0.09%), F=97.381, P>0.05).@*Conclusion@#Both the number and the cytokine secretion of CD4+ CD25+ Foxp3+ Treg cells are decreased in AR group, HRS may inhibit inflammatory response and ameliorate AR via improving the number and the cytokine secretion.
ABSTRACT
OBJECTIVE@#To discuss the clinical features and treatment methods for simple orbital blowout fracture.@*METHOD@#Retrospective analysis of the CT images of 16 orbital blowout fracture case, and identification of the sites, degree, patterns and features of fractures. Among the 16 cases, 2 cases adopted conservative treatment; 11 cases gained a reduction of orbital fracture through endoscopic transnasal surgery; the other 3 patients choosed endoscopic transnasal surgery and Caldwell-Luc operations.@*RESULT@#Among 16 diplopia cases, 13 cases were completely cured, and 3 patients' vision were significantly improved. Among 11 enophthalmos cases, 10 patients were cured, and the effect of the other one was not satisfied. Among the 15 eye movement disorder cases, 13 patients' eye movement gained a full recovery, and the other 2 cases were nearly normal. All patients' vision were improved in different extents, and no one got a complication.@*CONCLUSION@#Computerized Tomography is helpful to the diagnosis of simple orbital blowout fracture. Caldwell-Luc operation with transnasal endoscope is an effective method for the treatment of orbital fractures.
