ABSTRACT
Objective To investigate the development and prognosis of peroxisome proliferator-activated recepor-γ(PPAR-γ) and cyclooxygenase-2(COX-2) in endometrial carcinoma. Methods The electron microscopic immunohistochemical technique was used to observe the ultrastructure location of COX-2 protein labeled by colloidal gold in the endometrial carcinoma. Results 1.There were negative immunohistochemical staining signals of PPAR-γ in both the normal endometrium and hyperplasia endometrium, whereas, was positive staining in the endometrial carcinoma;2.The intensities of the COX-2 immunohistochemical staining were significantly statistical difference among the normal endometrium, the hyperplasia endometriu and the endometrial carcinoma(P<0.01);3. The COX-2 labelled by colloidal gold granules was observed in the endoplasmic reticulum, nuclear membrane and nuclei in the endometrial carcinoma. Conclusion Both PPAR-γ and the COX-2 might play an important role in the development of the endometrial carcinoma.
ABSTRACT
OBJECTIVE To compare the outcome measurement scores for hearing impaired people with hearing aids. Two kind of questionnaires of Chinese version--COSI and IOI-HA were developed in order to find out the more specific outcome measurements for hearing aid users in China. METHODS The COSI and IOI-HA were administered for 30 hearing aid users via telephone or by clinical interview. SPSS software was used to analyze the collecting data. RESULTS Five prevalent problems to which most of the people with hearing aids pay attention were summarized. The mean level of the satisfaction of all the participants was high. CONCLUSION The outcome measurement inventory reflects the major problems which patients concern most and it can be used to evaluate the aural intervention and rehabilitation. After further study, this method is worth extending clinical application.
