Purpose
Recent studies have indicated that constitutive NF-κB activity could be involved in the proliferation of triple-negative breast cancer.Methods
The NF-κB/p65 expression and the effects of a NF-κB inhibitor, (?)-DHMEQ, were examined in triple-negative MDA-MB-231 breast cancer cells. Women with triple-negative breast cancer treated with neoadjuvant chemotherapy between 2002 and 2012 were retrospectively analyzed for their expression of NF-κB/p65, Bcl2 and Ki67 by immunohistochemistry in pre- and post-treatment specimens. The factors predicting the response to neoadjuvant chemotherapy and the prognosis were analyzed.Results
NF-κB/p65 was predominantly expressed in the cytoplasm of MDA-MB-231 cells. Of 34 triple-negative breast cancer patients, positive staining for NF-κB/p65 expression was detected in the nuclei of a few cells in seven tumors before neoadjuvant chemotherapy, while the expression of NF-κB/p65 in the cytoplasm was detected in almost all tumor cells of 33 tumors. The expression levels of NF-κB/p65 were not associated with the response to neoadjuvant chemotherapy, although the cytoplasmic NF-κB/p65 staining intensity was significantly decreased in the post-treatment tumor samples compared with the pretreatment samples. All patients whose tumors showed strong cytoplasmic NF-κB/p65 expression before neoadjuvant chemotherapy are currently disease free.Conclusion
Our results suggest that strong cytoplasmic NF-κB/p65 expression could be a prognostic marker for patients with triple-negative breast cancer.3.

The purpose of this study was to investigate the histopathology, including apoptosis, in the supraspinatus tendon with stage II subacromial impingement. Samples from the critical zone of the supraspinatus tendon were obtained from 5 patients with subacromial impingement syndrome and 10 autopsy cases without shoulder diseases as controls. Three-micrometer-thick sections were cut and stained with hematoxylin-eosin (H-E) for routine histologic examination. Apoptosis was detected by terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labeling (TUNEL) method and single-stranded deoxyribonucleic acid (ssDNA) assay in which the frequency of the apoptotic cells was expressed by the apoptotic index. Control supraspinatus tendons showed normal morphology, whereas supraspinatus tendons from shoulders with impingement showed significant mucoid degeneration. Correspondingly, few apoptotic cells were observed in control tendons, whereas a large number of apoptotic cells were observed in the degenerative area of tendons from impingement shoulders. The apoptotic indices were significantly higher in the impingement shoulders (ssDNA, 18.84% +/- 1.75%; TUNEL, 24.92% +/- 2.79%) than in the control shoulders (ssDNA, 5.22% +/- 1.30%; TUNEL, 7.01% +/- 1.05%) (P = .04 for ssDNA and P = .017 for TUNEL). Mechanical impingement seems to cause tendon degeneration and apoptosis of the tendon cells in the supraspinatus tendon in stage II impingement. 相似文献

To evaluate the susceptibility of rasH2 mice to N-bis(2-hydroxypropyl)nitrosamine (DHPN), a potent carcinogen targeting the lung, liver, thyroid, and kidney, male, 6-week old, rasH2 mice and wild-type littermates (non-Tg mice) were given DHPN in drinking water at 0, 20 or 200 ppm, and 0 or 200 ppm, respectively, for 26 weeks. The experiment using rasH2 mice given 200 ppm DHPN and non-Tg mice given 200 and 0 ppm DHPN was completed at 20 weeks, since mortality in these groups was remarkably increased due to hemangiosarcomas of the liver. Histologically, tumors developed in the lung and liver in both rasH2 and non-Tg mice treated with DHPN. In addition, proliferative lesions were observed in the forestomach, urethra, and excretory duct of salivary glands in rasH2 mice given 200 ppm DHPN. RT-PCR analysis showed no marked difference in expression of mRNAs for the transgene and the endogenous mouse ras gene between the whole lung tissue containing a neoplasm and normal lung tissue. Our results suggest that rasH2 mice are highly susceptible to DHPN, the target organs including the forestomach, salivary gland and urethra, which have not been found to develop tumors in previous long-term carcinogenicity studies of DHPN in rats and mice. 相似文献

We report two cases of subacute inguinal swelling in uremic patients on continuous ambulatory peritoneal dialysis (CAPD). Computed tomography, scintigraphy demonstrated a mass in the right groin. Surgical repair of an inguinal hernia resulted in complete resolution of the inguinal swelling. Both patients could restart continuous ambulatory peritoneal dialysis, without complication. 相似文献

Wormwood, Artemisia absinthium, is a very bitter plant, and its extract has been used as food additives such as seasonings for food and drinks. A 13-week repeated dose toxicity study of wormwood extract was performed in both sexes of Wistar Hannover (GALAS) rats. Rats were divided into 4 groups consisting of 10 males and 10 females each, and were given water containing 0, 0.125, 0.5, or 2% wormwood extract. All rats had survived at the end of the study, and no changes indicating obvious toxicities that are attributable to the treatment of wormwood extract were observed in the body weights, hematological and serum biochemical examinations, organ weights, and histopathological examinations. Based on the results of the present study, the NOAEL (no-observed-adverse-effect-level) of wormwood extract of Wistar Hannover rats was estimated to be 2% (equivalent to 1.27 g/kg/day in males and 2.06 g/kg/day in females) or more. 相似文献

This preliminary prospective study was conducted to determine whether immobilization with the arm in external rotation would decrease the rate of recurrence after initial traumatic anterior dislocation of the shoulder. Forty patients with initial shoulder dislocations were assigned to (1) conventional immobilization in internal rotation (IR group, n = 20) or (2) a new method of immobilization in external rotation (ER group, n = 20). The recurrence rate was 30% in the IR group and 0% in the ER group at a mean 15.5 months. The difference in recurrence rate was even greater among those who were aged less than 30 years (45% in the IR group and 0% in the ER group). Immobilization with the arm in external rotation is effective in reducing the rate of recurrence after initial dislocation of the shoulder. 相似文献

Rotator cuff tendon cells (RCC) derived from surgical samples showed fibroblast-like morphology. Histological staining demonstrated collagen secretion by RCC. Immunohistological findings revealed that RCC secreted type I and III collagen, but not type II collagen. In addition, the SDS-PAGE analysis suggested that RCC predominantly produced type I collagen. Basic fibroblast growth factor (bFGF) had a stimulatory effect on the proliferation of RCC dose-dependently up to 1 ng/ml. Administration of bFGF suppressed the secretion of collagens from RCC in a dose-dependent manner. 相似文献
