One hundred fifty-three patients with hypoxia of both sexes,underwent hip arthroplasty from January 2012 to January 2014,aged 65-97 yr,weighing 41-80 kg,living in areas at altitude above 1800 m,of American Society of Anesthesiologists physical status Ⅱ-Ⅵ,were selected.The hemoglobin (Hb) at 3-4 days after operation was collected,and the patients were divided into 3 groups depending on whether or not postoperative anemia occurred:no anemia group (Hb＞ 110 g/L);mild anemia group (90 g/L≤ Hb≤ 110 g/L);moderate anemia group (70 g/L ≤ H b＜ 90 g/L).The 36-item Short-Form Health Survey score and Harris Hip Score at 28 days after operation were collected.There was no significant difference between the three groups in the postoperative 36-item Short-Form Health Survey score and Harris Hip Score (P＞0.05).Postoperative mild and moderate anemia did not affect the short-term outcome after hip arthroplasty in elderly patients in high-altitude regions.

OBJECTIVETo investigate the effect of lonidamine on apoptosis of human breast carcinoma cells MCF-7 and the possible mechanisms.

METHODSMTT assay and colony-forming assay were used to evaluate the growth inhibition induced by lonidamine in breast cancer MCF-7 cells. PI/Annexin-V staining was used to detect the apoptotic cells. The ATP levels in the cells were detected using an ATP assay kit. The expression of glucose regulated protein 78 (GRP78), inhibitor of apoptosis protein (cIAP1) and caspase-8 were analyzed with Western blotting.

RESULTSMTT assay and colony-forming assay showed that 50-250 mmol/L lonidamine caused a time- and concentration-dependent inhibition of MCF-7 cell proliferation. Exposure to increased concentrations of lonidamine resulted in significantly increased apoptosis rate in MCF-7 cells. In MCF-7 cells treated with 50, 150 and 250 mmol/L lonidamine for 5 h, the intracellular ATP levels were lowered to 80.67%, 62.78% and 30.73% of the control level, respectively. Western blotting showed that lonidamine up-regulated the expression of GRP78, down-regulated the expression of cIAP1 and promoted caspase-8 activation as the treatment time extended.

CONCLUSIONLonidamine can inhibit the proliferation and induce apoptosis in MCF-7 cells, and these effects are probably mediated by reducing ATP level, inducing endoplasmic reticulum stress response, down-regulating cIAP1, and promoting caspase-8 activation in the cells.
