ABSTRACT
Objective:To analyze the expression and relationship of miR-379 and human kinesin family member 4A (KIF4A) in triple-negative breast cancer (TNBC).Methods:A total of 52 patients diagnosed with TNBC in breast department at Puji Branch of Dongguan People′s Hospital between January 2016 and November 2019 were retrospectively selected as the study group. Meanwhile, 70 patients with non-triple-negative breast cancer (NTNBC) diagnosed in the same period were selected as the control group. The expression levels of miR-379 and KIF4A in both groups were detected. The receiver operating characteristic (ROC) curve was drawn, and the area under the curve (AUC) of miR-379 and KIF4A predicting TNBC was calculated; The relationship between the expression levels of miR-379 and KIF4A and clinicopathological parameters, and the correlation between the expression level of miR-379 and KIF4A were analyzed.Results:The expression level of KIF4A in study group was higher than that in control group [(6.93±0.43) vs (3.75±0.25), P<0.05], and the expression level of miR-379 in study group was lower than that in control group [(0.54±0.17) vs (0.87±0.32), P<0.05]. MiR-379 combined with KIF4A expression had the greatest diagnostic value for TNBC: AUC 0.823 (95% CI: 0.730- 0.917), specificity 0.785, sensitivity 0.950; Univariate analysis showed that there were significant difference in the expression of miR-379 in TNBC patients with different clinical stages, tumor diameter, and lymph node metastasis (all P<0.05); There were significant difference in the expression of KIF4A in TNBC patients with different clinical stages and tumor diameter (all P<0.05). Pearson correlation analysis showed that miR-379 expression was negatively correlated with KIF4A expression in TNBC ( r=-0.349, P<0.05). Conclusions:The expression of miR-379 is down-regulated, while the expression of KIF4A is up-regulated in patients with TNBC. The two are related to poor clinicopathological characteristics, which indicates that they can be used for condition evaluation of the patients.
ABSTRACT
Objective To study the clinical effect of plastic operation treated to vice- mammary gland located armpit ,s forepart. Methods Two hundred patients of vice- mammary gland separately were carried on the armpit plastic operation (study group)and the pure vice- mammary gland excision operation (control group),and compared the curative effects between two groups. Results Two groups is not obvi-ous difference in the surgery time,the hemorrhage quantity,the margin heal and so on (P > 0.05 ),In the out-ward appearance of armpit after the operation,plastic operation demonstrates the good effect. Two sets were in surgical operation time,the hemorrhage quantity and slice a people match to wait the aspect to all had no obvious difference more ( P > 0.05),but after operation the external appearance armpit plastic surgery dis-plays good result ( P < 0.05). Conclusion Armpit department reshaping technique treatment for the vice-mammary gland effect is good,is worth promoting. Vice- mammary glands result is good,deserving the expansion. The armpit plastic surgery cures the vice- mammary glands in forepart in armpit at cut off the disease cooking stove to have to make up the result concurrently at the same time,design reasonable,operation simple,deserve expansion.
ABSTRACT
Objective To discuss the efficacy of fiberoptic ductoscopy(FDS)in the treatment of mammary duct diseases with nipple discharge.Methods Fiberoptic ductoscopy was utilized for diagnosing and treating exudative lesions in the mammary duct in 72 cases(80 sides).After the lesion was detected under ductoscope,repeated irrigation using normal saline was performed until the flocculent discharge disappeared.Intraductal drug administration(dexamethasone 5 mg and gentamycin 40 000 U)was given during the retreat of ductoscope.Results There were 57 sides of galactophoritis and 23 sides of mammary duct ectasia.A complete recovery was achieved in 65 sides(nipple discharge disappeared completely and no relapse occurred in 6 months),in which a follow-up for 1～2 years showed no recurrence.A remarkable improvement was obtained in 15 sides(nipple discharge significantly reduced,or progressively decreased within 6 months,or underwear wetted occasionally).Conclusions Fiberoptic ductoscopy in the treatment of mammary duct lesions with abnormal nipple discharge is effective.
