SiO2刺激矽肺肺泡巨噬细胞对MMP-9和TIMP-1表达的影响

Objective To investigate the effect of SiO2 on the expression of matrix metalloproteinase-9 (MMP-9)and tissue inhibitor of metalloproteinase-1 (TIMP-1)in human silicofic alveolar macrophages (AM).Methods Human alveolar macrophages were collected from a silicotic patient by bronchoalveolar lavage and exposed to silicon dioxide for 3h,6h,12h,18h,24h and 36h.The expression of the MMP-9 in the AM were detected with zymography and immunological method and the expression of the TIMP-1 in the AM with immunological method.Results The expressions of MMP-9 in the AM increased clearly along with the time,reached peak at 24 h when detected with zymography (average optical density:3.061±0.153 vs 2.851±0.164,P＜0.05);and reached peak at 18h when detected with immunological method (average optical density:0.386±0.037 vs 0.322±0.034,P＜0.05).The expression of the TIMP-1 in the AM did not vary when detected with immunological method (P＞0.05).Conclusion SiO2 may affect the expression of MMP-9 and MMP-9 activity in the cultured AM.     

与压力性尿失禁面对面

已经年过三十的李茹（化名），看起来比实际年龄年轻很多，周围的人都很羡慕她。但是她最清楚自己说不出的苦，事情是从“下边”开始的。这一年来李茹很痛苦。她的小便好像越来越不受控制了。有时稍微用力打个喷嚏、咳嗽、大笑、蹲下捡东西……只要是爆发性的小动作，     

被忽视的23个爱的细节

有一则小幽默：妻子问丈夫：亲爱的，为什么结婚后你不再送我鲜花了？丈夫回答：既然鱼已经钓到了，何必再浪费鱼饵呢？此虽笑谈，却不免令许多妻子心有共鸣。难道平淡生活中的丈夫，真的失去往日的爱意了吗？

Dietary modulation of 7,12-dimethylbenz[a]anthracene (DMBA)-induced adrenal toxicity in female Sprague-Dawley rats.

In this study, dietary modulation of 7,12-dimethylbenz[a]anthracene (DMBA)-induced adrenal toxicity in rats was investigated. Beginning at postnatal day (PND) 21, female Sprague-Dawley rats were fed either soy-containing NIH-31 diet or soy- and alfalfa-free 5K96 diet. On the first day of diestrus when the animals were PND 50 +/- 5, rats received either an oral dose of 80 mg/kg DMBA or sesame oil, the vehicle, and were sacrificed at 24, 36, or 48 h after treatment. Apoptosis was manifested at 24 and 36 h after DMBA treatment in the zona reticularis (ZR) and the zona fasciculata (ZF) of the adrenal cortex; this was followed by severe hemorrhagic necrosis at 48 h. DMBA-induced apoptosis, evaluated by the TUNEL assay, immunohistochemical analysis of activated caspase 3, and the ratio of expression of pro-apoptotic Bax to anti-apoptotic Bcl2, was greater in rats fed NIH-31 diet relative to rats fed 5K96 diet at 24 h after treatment. Four of six DMBA-treated rats fed 5K96 diet had severe adrenal necrosis by 48 h, whereas this lesion was present in only two of six DMBA-treated rats fed NIH-31 diet. DMBA also caused a significant decrease of serum corticosterone relative to controls at 48 h in rats fed 5K96 diet. The present study indicated that diet modulates DMBA-induced adrenal toxicity in female rats, with increased apoptosis early and reduced necrosis later in rats fed a soy-containing diet.
