The optimal blank microemulsion was used as a solvent to sonicate the Ganoderma lucidum powder to prepare the multicomponent microemulsion, besides, its physicochemical properties were compared with the microemulsion made by conventional method. The results showed that the multicomponent microemulsion was characterized as (43.32 +/- 6.82) nm in size, 0.173 +/- 0.025 in polydispersity index (PDI) and -(3.98 +/- 0.82) mV in zeta potential. The contents of Ganoderma lucidum triterpenes and polysaccharides were (5.95 +/- 0.32) and (7.58 +/- 0.44) mg x mL(-1), respectively. Sonicating Ganoderma lucidum powder by blank microemulsion could prepare the multicomponent microemulsion. Compared with the conventional method, this method is simple and low cost, which is suitable for industrial production.

OBJECTIVE: To analyze external factors affecting auditory ability of infants and toddlers after cochlear implantation in the first year of switch-on. METHOD: Seventy-five infants and toddlers after cochlear implantation were selected as subjects, using LittlEARS Auditory Questionnaire to assess and analyze the correlations with auditory ability and external factors (including gender, cochlear implanted age, pre-implant hearing aid fitting, caregivers' education background, household income and rehabilitation modes) in different stages (before switch-on, and 3 months, 6 months, 9 months, 12 months after switch-on). RESULT: The mean scores of LittlEARS were significantly different in cochlear implanted age group, pre-implant hearing aid fitting group and rehabilitation modes group (P < 0.05), and there was no significant difference in other groups such as external factor gender, caregivers' education background and household income (P > 0.05). The correlations with the mean scores of LittlEARS and cochlear implantation age or pre-implant hearing aid fitting were significant at 3 months or 6 months after switch-on(/r/ ≥ 0. 3, P < 0.01). However, the correlation with the mean scores of LittlEARS and rehabilitation modes was significant at 12 months after switch-on(/r/ > ≥ 0.3, P < 0.01). CONCLUSION Cochlear implanted age and pre-implant hearing aid fitting were the important factors affecting auditory ability of infants and toddlers after cochlear implantation in the first year of switch-on. The effect of rehabilitation modes on auditory ability of infants and toddlers after cochlear implantation was slow.

Objective To study the correlations among lumbosacral anatomical structure variations and herniation of intervertebral disc.Methods Through analyzing lumbar CT images of 684 patients with lumbocrural pain between 15 to 24 years old, the anatomical variations of spondylolysis, scoliosis deformity, lumbosacral transitional vertebra, subfissure, lumbosacral angle and others (including vertebral muscles beside, spines, transverse process on both sides) were observed, and the correlations among these anatomical variations and herniation of intervertebral disc were analyzed.Results The correlations among these above mentioned anatomical variations and herniation of intervertebral disc were 93.6%,92.3%,87.5%,81.3%,72.1%,53.3% respectively.In 91.4% of patients, the lumbosacral anatomical structure variations suffered herniation of intervertebral disc at the same time.But only 36.2% of patients suffered herniation of intervertebral disc without lumbosacral anatomical structure variations.Conclusion Lumbosacral anatomical structure variation is the main reason of herniation of intervertebral disc on teenagers.CT examination,which can reflect the correlation between them.

Background and purpose: The literature on dose-volume parameters and pneumonitis is extensive. The results are inconsistent, both for the best predictive metrics and significant comorbid factors. This study aimed to investigate a prospective functional equivalent uniform dose (fEUD) with perfusion single photon emission computed tomography (SPECT) images as predictors of radiation pneumonitis (RP) in patients undergoing curative radiotherapy (RT). Methods: Functional lung imaging was performed using SPECT for perfusion imaging. Perfusion factors were defined as the mean percentile perfusion levels of the 4 areas, top to 75%, 75% to 50%, 50% to 25%, 25% to 0%, re-spectively. fEUD was calculated from perfusion factors and standard dose-volume parameters extracted from treatment planning computed tomography (CT) scans. Total lung (TL), ipsilateral (IL) and contralateral lung (CL) volumes minus gross tumor volume (GTV), whole-lung V5, V20, whole lung fEUD, IL and CL fEUD, and general equivalent uniform dose (gEUD) were analyzed to evaluate correlations between RP using Common Terminology Criteria for Adverse Events (CTCAE) version 4.03. Statistical significance was defined as P<0.05. Results: A total of 15 patients treated with intensity modulated RT or 3D conformal RT were analyzed, grades≥3 RP were observed in 6 patients. There was only a trend toward significance for unilateral (UL) fEUD of higher dose side (P=0.007). Whole-lung V5, V20 were almost identical between patients who developed pneumonitis and patients who did not, as the values were below the recommended thresholds from published papers. Unilateral fEUDs were linear with unilateral gEUDs (t=0.815, P=0.000). Conclusion: SPECT-based equivalent uniform dose appears to be a better predictor of RP compared to stan-dard dose-volume parameters. Planning constraints should aim to keep unilateral fEUD below 21 Gy.
