005), while iron overload occurred in 8 of 57 cases of ?-thalassemia (14.0%) and 89 out of 386 cases of ?-thalassemia (23.1%). Although the occurrence rate of iron overload in ?-thalassemia appeared higher than that in ?-thalassemia, no significant difference existed. Homozygote ?-thalassemia was prone to iron overload, followed by non-deletion HbH diseases, at the occurrence rate of 79.2% and 27.3% respectively. Iron deficiency was inclined to be associated with silent ?-thalassemia at the occurrence rate of 45.5%, followed by heterozygote ?-thalassemia (30.3%). Conclusion Both iron overload and iron deficiency can be found in thalassemia. Therefore, special treatments should be carried out according to given cases.

OBJECTIVE:
To study the therapeutic effects of the specific immunotherapy (SIT) on allergic rhinitis and allergic rhinitis combined bronchial asthma. METHED: All patients were classified into allergic rhinitis group (AR group) with 32 patients and allergic rhinitis combined bronchial asthma group (AR+BA group) with 32 patients. Another health control group with 32 cases was designed as well. The allergens,symptom scores and therapeutic effects of the former two-group patients were analysis, and the serums of all three-group cases were extracted to evaluate the specific Immunoglobin E(sIgE), Interleukin-4 (IL-4). The SPSS13. 0 package was applied to conduct t-test and chi-square test, and the difference of P<0. 05 was regarded as statistical significance.
RESULT:
The main allergens of 64 patients were dermatophagoides farinae and dermatophagoides pteronyssinus. The improvement of symptom scores before and after SIT was statistical significant with P<0. 05. Although total effective rate reached 100% , AR group was superior than AR+BA group in term of the efficacy comparison, and P<0. 05 indicated the statistical significance. The serum sIgE, IL-4 values of three groups were brought into comparison, and P<0. 05 indicated the statistical significance of the difference.
CONCLUSION
The SIT on the AR, AR+BA is a safe and effective treatment, but different disease responds diversely. The long-term treatment course is recommended.
