RESUMO

OBJECTIVE@#To analyze the correlation of the tympanic injection of triamcinolone acetonide, middle ear pressure (MEP) and radioactive secretory otitis media (RSOM) with nasopharyngeal carcinoma (NPC) after radiotherapy.@*METHOD@#Fifty-two patients suffering NPC without otitis media before radiotherapy were randomly divided into three groups. 17 cases with 34 ears were distributed into treatment group I, and radiotherapy 1 hour before the start of each side of the tympanic cavity injection of triamcinolone acetonide injection, 1-7 weeks 1 times a week. Treatment group I had 17 cases with 34 ears,and radiotherapy 1 hour before the start of each side of the tympanic cavity injection of triamcinolone acetonide injection, 1-12 weeks 1 times a week. And control group consisted of 18 cases with 36 ears who didn't accept such treatment. In all 104 ears, MEP was tested at the begin of radiotherapy and the end of 1st, 2nd, 3rd month after radiotherapy.@*RESULT@#From the beginning of radiotherapy to the end of th 1st, 2nd, 3rd month after radiotherapy, the morbidity of RSOM gradually increased and MEP decreased in the treatment group I , II and the control group, in which treatment group II showed the lowest morbidity of RSOM and MEP was maximum (P 0.05).@*CONCLUSION@#Tympanic injection of triamcinolone acetonide could reduce radiation injury, and medication time was positively correlated with the MEP, and a negative correlation with RSOM morbidity, and the longer treatment, the more significant the effect is. The difference is most obvious at the end of 3rd month after radiotherapy. It may be due to the more active repairation after radiation damage in middle ears, but long-term efficacy must continue to observe.

RESUMO

Objective To determine the importance of aneuploidy screening in preimplantation genetic diagnosis for the couples of chromosome translocation carriers. Methods To perform 11 prenatal genetic disgnosis (PGD) cycles for 7 couples of chromosome translocation carriers from January 2006 to March 2009 in the Reproductive Medical Center, First Affiliated Hospital of Zhengzhou University. To re-analyze the well-fixed, non-multinuclear and non-debris nuclei using the probes of LSI 13, 18, 21,CEPX, CEPY to detect the aneuploidy rate which come from the PGD cycles of the couples of chromosome translocation carriers. The euploid embryo was defined as two fluorescence in situ hybridization (FISH)signals of LSI 13, 18, 21 respectively and two signals of CEPX, or one signal of CEPX and one signal of CEPY. The other abnormal signals were defined as aneuploid embryo. Results (1) A tolal of 130 nuclei from 11 PGD cycles got the integrated re-FISH signals. Nine hundred and thirty-seven FISH signals were analysized, including 304 signals from 38 euploid nuclei and the others from 92 aneuploid nuclei. (2) The number of the aneuploid nuclei from grade Ⅰ , Ⅱ and Ⅲ embryo was 20 (22%), 36(39%), and 36(39%). The number of the euploid nuclei from grade Ⅰ , Ⅱ and Ⅲ embryo was 13(34%), 17(45%),and 8(21%). There was no significant difference of aneupioidy rate between the embryos form different grades (P>0.05). However, the rate of aneuploid nucleus from good quality embryos (grade Ⅰ + grade Ⅱ) was 60% (59/92). (3) The euploidy rate was 71.4% (30/42) from balanced embryos, while 9.1%(8/88)from unbalanced embryos. There was significant difference between them (x2=53.4, P<0.05).The rate of aneuploidy from balanced embryos was lower than those from unbalanced embryos (P<0.05).Conclusions Since higher rate of aneuploidy was detected in embryos of the couples of chromosome translocation carriers. It is advisable to recommend the FISH re-analysis for aneuploidy screening to preimplantation genetic diagnosis for the couples of chromosome translocation carriers.
