ABSTRACT
Objective To detect the expressions of HuR and COX-2 in epithelial ovarian carcinoma,and investigate the correlation of HuR and COX-2 expression. In addition, we attempt to seek the pathway to prevent the occurrence and development of epithelial ovarian cancer by combined analysis of various clinicopathologic characteristics. Methods The expressions of HuR and COX-2 in 68 epithelial ovarian carcinoma, 10 borderline ovarian tumors and 5 normal ovarian tissues were examined by S-P immunohistochemical method. The relationship of HuR and COX-2 expressions with clinicopathologic parameterwere evaluated by correlation analysis. Results(1) The expression of HuR in epithelial ovarian cancer tissue (76. 47% ,52/68) was significantly higher than that in borderline epithelial ovarian tumor tissues (30. 00% ,3/10) and normal ovarian tissues (0, x2 = 18. 873, Ps ＜ 0. 05), but there were no significant differences betweenthe expressions of HuR in borderline epithelial ovarian tumor and normal ovarian tissue(P ＞ 0. 05).(2) The positive expression rate of cytoplasmic HuR in epithelial ovarian carcinoma and borderline epithelial ovarian tumor were 45.60% (31/68) and 10. 00% (1/10) respectively,but normal ovarian tissues showed no staining of HuR. We found no significant differences between the expression of cytoplasmic HuR in epithelial ovarian carcinoma and borderline epithelial ovarian tumor or normal ovarian tissue(x2 = 7. 999 ,P =0. 018).(3) The positive expression rate of cytoplasmic HuR in epithelial ovarian carcinoma of FIGO stage Ⅲ - Ⅳ was significantly higher than that of stage Ⅰ - Ⅱ(56. 09% vs. 29. 63%, x2 = 4. 598, P = 0. 032). The positive expression rates of cytoplasmic HuR in epithelial ovarian carcinoma of histological grade 1,2,3 were 10. 00%,46. 67% ,57. 14% respectively, which showed significant difference in the comparison among the three groups (x2 =6. 627 ,P =0. 036). (4) The positive expression rates of COX-2 in epithelial ovarian cancer (67. 64%)and borderline epithelial ovarian tumor tissues (60. 00%) were significantly higher than that in normal ovarian tissues (0, Ps ＜ 0. 05), but we found no significant difference in the comparison between the expression of malignant and borderline ovarian tumors. Statistical analysis showed that the positive expression rate of COX-2 in epithelial ovarian carcinoma was correlated with FIGO stage and lymph node metastasis. (5)There was a significantly positive correlation between cytoplasmic HuR and COX-2 expressions in epithelial ovarian carcinoma. Conclusion The expressions of HuR and COX-2 increased in the epithelial ovarian carcinoma, and the cytoplasmic expression of HuR was significantly correlated with the expression of COX-2. These results suggested that increased cytoplasmic expression of HuR and COX-2 expression might play important roles in the initiation and development of epithelial ovarian carcinoma.
ABSTRACT
Objective To discuss the effect of self- care education at the early time of postoperation and the use of nursing packages during the later period on non- throat patients. Methods 40 patients having un-dergone total laryngectomy were divided into the control group and the experimental group according to the surgery date with 20 cases in each group. The control group received conventional nursing, while the experi-mental group was given the system intervention by specialized nurses. The intervention content included self-care education at the early time of postoperation and the use of nursing packages during the later period. The questionnaire survey was carried out 15 days and 3 months after operation.The coping style,self-care ability and survival quality were compared between the two groups. Results The comparison of coping style showed re-markable difference in the two groups. The comparison of self- care ability and level of health knowledge showed significant difference 15 days after operation except two other items,but the four items demonstrated significant difference 3 months after operation. Difference also existed in the total scorn of survival quality. Conclusions Early system serf- care education after operation and the use of nursing package during the later period can impel the patients to cope positively, enhance self-care ability and survival quality.
