Objective: To research advanced glycation end-product receptors (RAGE), NF-kappaB, p21 expressions in C57BL/6j mice cochlea spiral ganglion cells(SGC) ,and then to investigate the presbycusis pathogenesis., Method: To take C57BL/6J mice:2 month 25,and 10 month 25. Histological sections were observed the SGC. RAGE, NF-kappaB, p21 were immunohistochemical in the SGC,with IPP6 to IOD., Result: (1) The count SGCs of 10 month-old was obviously decreased comparing to 2 month-old, the count of 2 month SGC is 39 +/- 5, 10 month group is 20 +/- 6, P < 0.01; (2) RAGE, NF-kappaB, p21 expressed in spiral ganglion cell,different place with different age,and the means optical density in the 10 month are higher than the 2 month, respectively. The IOD of RAGE expression in 2 month SGC: 0.179 +/- 0.025, 10 month IOD: 0.308 +/- 0.050; The IOD of NF-kappaB expression in 2 month SGC: 0.181 +/- 0.045, 10 month IOD: 0.335 +/- 0.120; The IOD of p21 expression in 2 month SGC: 0.160 +/- 0.023, 10 month IOD: 0.365 +/- 0.031, compare with 2 group, respectively, P < 0.05, and the difference has statistics sense., Conclusion: RAGE,NF-kappaB, p21 expressions are in SGCs and increases with the aging of SGCs, suppose RAGE, NF-kappaB, p21 may participate in the process of presbycusis pathogenesis.

Objective: To investigate the variation on different regions of the forearm when taking the allergen skin prick tests(SPTs)., Method: Forty-one patients with hyper-reactive nasal symptoms were included. SPTs were done on the proximal, telecentric, middle region of right forearm and telecentric region of left forearm with house dust mite and histamine. The average diameter of wheal and the reactive grade were calculated and analyzed., Result: The diameters of the wheal on equal position of two forearms were similar (P > 0.05). The intension of SPTs reaction decreased from proximal to telecentric region of the same forearm (P < 0.05)., Conclusion: The intension of SPTs reaction on different region of forearm are quite different, which should be noticed in clinical practice.

Objective: To evaluate the efficacy of specific immunotherapy (SIT) with standardized dermatophagoides pteronyssinus extract for allergic rhinitis (AR)accompanied with asthma., Method: One hundred and fifty-five patients (40 AR with asthma, AR & asthma) in accordance with the inclusion criteria of SIT, were allocated to receive standardized Dermatophagoides pteronyssinus extract (SIT group, n = 89) or medical treatment (control group, n = 66). AR with or without asthma was observed separately. Symptom and medicine scores, quality of life were recorded and analyzed before and after 1 year treatment. Side effects were registered. Subjective evaluation of symptoms was made by the patients., Result: Rhinitis and asthma symptom scores, medicine scores and quality of life were greatly improved in SIT group of AR & asthma after 1 year, which were not significant changed in control group except for medicine scores. The subjective evaluation of symptoms was also significantly improved in SIT group. In patients of AR without asthma, the symptom scores, medicine scores and quality of life were both improved. The SIT group improved greater than that of control group., Conclusion: The clinical efficacy of patients with AR & asthma was not good with simple medical treatment, while great clinical efficacy could be acquired with SIT.
