ABSTRACT
Objective:To investigate the expression of circ0008234 and miR-1205 in breast cancer and the oncology characteristics of CT.Methods:40 patients with breast cancer were collected as observational objects from Jan.2018 to Dec.2018 and 40 patients without breast cancer were selected as the control group. The expression levels of circ0008234 and miR-1205 of all patients were estimated by quantitative real-time polymerase chain reaction. Bioinformatics was used for the predictions of circ0008234 target miRNA. A dual-luciferase reporter assay was used to confirm the interaction between circ0008234 and miR-1205. All patients of the observation group were examined by multi-slice CT. CT images were analyzed through observing tumor size, shape, calcification area, lymph node metastasis and margin. The correlation between CT signs and the expression of circ0008234 and miR-1205 was further analyzed.Results:The levels of circ0008234 of observation group were significantly higher than those of the control group (2.23±0.86, 1.07±0.37, P=0.00) , but the expression levels of miR-1205 were lower than the control group (0.76±0.29, 1.04±0.29, P=0.00) . In the observation group, there were no significant differences in the expression of circ0008234 and miR-1205 among patients with different tumor marginal morphology and micro calcifications. However the expression of circ0008234 in patients with regular lump form were significantly higher than those in patients with inregular form (2.52±0.88, 1.91±0.74, P=0.025) , and the expression of miR-1205 were lower than those in patients with inregular form (0.66±0.30, 0.86±0.25, P=0.025) . In the observation group, the expression of circ0008234 in patients with mass diameter≥2 cm were significantly higher than those in patients with mass diameter<2 cm (2.59±0.95, 1.69±0.17, P=0.001) , but the expression of miR-1205 were lower than those in patients with mass diameter<2 cm (0.65±0.21, 0.92±0.33, P=0.003) . In the observation group, the expression of circ0008234 in patients with lymph node metastasis were higher than those without lymph node metastasis (2.55±1.09, 1.94±0.44, P=0.022) , but the expression of miR-1205 in patients with lymph node metastasis were lower than those without lymph node metastasis (0.65±0.26, 0.85±0.30, P=0.027) . miR-1205 was verified as a direct target of circ0008234 by luciferase assay. circ0008234 could negatively regulate the expression of miR-1205. Conclusion:There is a correlation between CT imaging signs and the expression of circ0008234 and miR-1205 in patients with breast cancer, which can provide more reference for the judgment of malignant degree and prognosis of patients with breast cancer.
ABSTRACT
Objective To summarize the experience in nursing locally preserved skin of female patients for neurosurgical cranioctomy. Method The nursing key points were given to 66 female patients undergoing local preparation of skin for cranioctomy as follous preoperative preparation, observation over incision and head nursing. Results The time for skin preparation ranged between 3 to 6 minutes. Postoperatively, no drain tube was placed. No intracranial infections occurred. The incisions in all patients were healed at the first class. Conclusion The nursing measures of good preoperative preparation, close observation of incisions and care to the head for female patients undergoing local preparation of skin for cranioctomy can enhance their satisfaction and propel development of standardized nursing.
