April 27 精进修行今天中午在我的小房间里看书
突然回想起考GRE那会儿也是这样
一个人关在小房间里
夜以继日的看
那时的孤独与痛苦,总是深深啮食着我
又想起佛教有云
高高山上立
深深海底行
只有通过孤独的修炼和寂寞的学习
才能智慧增长,达到幸福的彼岸 April 25 设立对照无论是临床试验还是基础研究
设立正确的对照非常重要
比方说染胞内或者核内抗原的流式细胞术
会存在破膜不成功、染不上、或者背景噪音太大的问题
这时设立正确的阴性和阳性对照对实验的成败非常重要
April 16 Kerley's A, B, and C linesA 59-year-old woman with hypertension and diabetic nephropathy presented with a sudden onset of dyspnea after discontinuing her medications. Physical examination revealed hypertension (blood pressure, 225/122 mm Hg), tachycardia (heart rate, 112 bpm), tachypnea (24 breaths per minute), and hypoxemia (oxygen saturation, 94%, despite treatment with supplemental oxygen). The patient also had elevated jugular venous pressure, bilateral rales, and edema of the legs. The level of brain natriuretic peptide was elevated (780.8 pg per milliliter; normal level, <18.4). A chest radiograph showed an enlarged cardiac silhouette, a dilated azygos vein, and peribronchial cuffing, in addition to Kerley's A, B, and C lines. Kerley's A lines (arrows) are linear opacities extending from the periphery to the hila; they are caused by distention of anastomotic channels between peripheral and central lymphatics. Kerley's B lines (white arrowheads) are short horizontal lines situated perpendicularly to the pleural surface at the lung base; they represent edema of the interlobular septa. Kerley's C lines (black arrowheads) are reticular opacities at the lung base, representing Kerley's B lines en face. These radiologic signs and physical findings suggest cardiogenic pulmonary edema. The patient's condition improved on treatment with diuretics and vasodilators. from NEJM 2009.4.9 April 04 Principles of writing readably1. structuring sentences simply

老陈杏的船家鱼鲜嫩香辣
morning里的民谣演唱
张小饼和熊熊,一胖一瘦,一土一洋
搭配得恰到好处,相得益彰
还有两个顶顶不错的书店
内敛、静谧,像一杯略带甜味的绿茶
一排拆迁房里的苍蝇馆子
喧嚣、鼎沸,像一口翻腾的火锅
就连送我们回家的出租师傅也那么有趣
这怎能不是一个美妙的周五夜晚?
