Objective To study the clinic significance of allergen serum immunoglobulin E (IgE) detection for the flying personnel with allergic rhinitis.Methods One hundred and twentyeight flying personnel with clinically suspected allergic rhinitis were drawn 2 ml venous blood.Serum tIgE (total IgE) and 14 allergen sIgE (specific IgE) including 7 aspiration allergens and 7 food allergens were detected with antibody kit.Strong positive reaction rates of the flying personnel with aspiration allergens and food allergens were compared as well as the correlation of serum tIgE and positive reaction rate of allergen sIgE was analyzed.Results Positive reaction rate of tIgE in 128 flying personnel with allergic rhinitis was 85.9 ％ (110/128) and positive reaction rate of sIgE was 91.4％ (117/128).The top 3 positive reaction rates of aspiration allergens were dust mite (66.4％),tree combination (32.8％) and house dust (23.4％).The top 3 positive reaction rates of food allergens were fruit combination (mango/pineapple/apple/peach/strawberry) (18.0％),seafood combination (shrimp/crab/scallop) (16.4％) and fish combination (ling/trout/weever) (13.3％).Positive response rate of the flying personnel with both aspiration and food allergens was 12.5 ％ (16/128).The aspiration allergens mainly reflected as strong positive reaction while the food allergens mainly expressed as weakly positive reaction.The strong positive reaction showed significance between aspiration and food allergens.(x2=16.881,P＜0.05).The strong positive reaction of allergen serum had the positive correlation to tIgE value (r=0.517,P＜0.01).Conclusions The allergen serum IgE detection have shown its objective,accurate and noninvasive advantages and are with less age,disease,medication,manipulation and other external limitations.The test results can be quantitatively or semi-quantitatively expressed and can determine tIgE level within the detection.So it has certain clinical significance on diagnosis,treatment,evaluation and prevention for the flying personnel with allergic rhinitis.

BACKGROUND: Percutaneous vertebroplasty for osteoporotic vertebral compression fractures has achieved very good results, but its long-term efficacy as well as impact on patients has been rarely reported so far.OBJECTIVE: To investigate the long-term effect of vertebroplasty with bone cement on osteoporotic vertebral compression fractures through a follow-up.METHODS: Thirty-four patients with osteoporotic vertebral compression fractures who had undergone percutaneous vertebroplasty were recruited. Visual analogue scale scoring was measured and compared as well as lesioned vertebral height and kyphosis angle shown on lateral X-ray examination prior to, 1 week and 6 years after percutaneous vertebroplasty.RESULTS AND CONCLUSION: The kyphosis angle was improved 1 week and 6 years after percutaneous vertebroplasty, and it changed insignificantly during the follow-up period. The vertebral height was also improved significantly after percutaneous vertebroplasty (P < 0.01); however, there was no obvious variation in the vertebral height at 1 week and 6 years after percutaneous vertebroplasty. The visual analogue scale exhibited an improvement after percutaneous vertebroplasty (P < 0.01); however, with time going by, the scoring on the visual analogue scale had an increased tend. All the parameters remained stable and had no large fluctuations. It is proved that the percutaneous vertebroplasty is effective and safe to treat osteoporotic vertebral compression fractures with an excellent long-term effect.
