电脑丁友梅慌%在下朋友拿来!On DoorsChristopher MorleyThe opening and closing of doors are the most significant actions of man's life. What a mystery lies in doors!No man knows what awaits him when he opens a door. Even the mostfamiliar room, where the clock ticks and the hearth glows red at dusk, may harbor surprises. The plumber may actually have called (while you were out) and fixed that leaking faucet. The cook may have had a fit of the vapors and demanded her passports. The wise man opens his front door with humility and a spirit of acceptance.Which one of us has not sat in some ante-room and watched theinscrutable panels of a door that was full of meaning? Perhaps you were waiting to apply for a job; perhaps you had some "deal" you were ambitious to put over. You watched the confidential stenographer flit in and out, carelessly turning that mystic portal which, to you, revolved on hinges of fate. And then the young woman said, "Mr. Cranberry will see you now." As you grasped the knob the thought flashed, "When I open this door again, what will have happened?"There are many kinds of doors. Revolving doors for hotels, shops and public buildings. These are typical of the brisk, bustling ways of modern life. Can you imagine John Milton or William Penn skipping through a revolving door? Then there are the curious little slatted doors that still swing outside denatured bar-rooms and extend only from shoulder to knee. There are trapdoors, sliding doors, double doors,stage doors, prison doors, glass doors. But the symbol and mystery of a door resides in its quality of concealment. A glass door is not a door at all, but a window. The meaning of a door is to hide what lies inside; to keep the heart in suspense.Also, there are many ways of opening doors. There is the cheery push of elbow with which the waiter shoves open the kitchen door when he bears in your tray of supper. There is the suspicious and tentative withdrawal of a door before the unhappy book agent or peddler. There is the genteel and carefully modulated recession with which footmen swing wide the oaken barriers of the great. There is the sympathetic and awful silence of the dentist's maid who opens the door into the operating room and, without speaking, implies that the doctor is ready for you. There is the brisk cataclysmic opening of a door when the nurse comes in, very early in the morning--"It's a boy!"Doors are the symbol of privacy, of retreat, of the mind's escape into blissful quietude or sad secret struggle. A room without doors is not a room, but a hallway. No matter where he is, a man can make himself at home behind a closed door. The mind works best behind closed doors. Men are not horses to be herded together. Dogs know the meaning and anguish of doors. Have you ever noticed a puppy yearning at a shut portal? It is a symbol of human life.The opening of doors is a mystic act: it has in it some flavor of the unknown, some sense of moving into a new moment, a new pattern of the human rigmarole. It includes the highest glimpses of mortal gladness: reunions, reconciliations, the bliss of lovers long parted. Even in sadness, the opening of a door may bring relief: it changes and redistributes human forces. But the closing of doors is far more terrible. It is a confession of finality. Every door closed brings something to an end. And there are degrees of sadness in the closing of doors. A door slammed is a confession of weakness. A door gently shut is often the most tragic gesture in life. Every one knows the seizure of anguish that comes just after the closing of a door, when the loved one is still near, within sound of voice, and yet already far away.The opening and closing of doors is a part of the stern fluency of life. Life will not stay still and let us alone. We are continually opening doors with hope, closing them with despair. Life lasts not much longer than a pipe of tobacco, and destiny knocks us out like the ashes.The closing of a door is irrevocable. It snaps the packthread of the heart. It is no avail to reopen, to go back. Pinero spoke nonsense when he made Paula Tanqueray say, "The future is only the past entered through another gate." Alas, there is no other gate. When the door is shut, it is shut forever. There is no other entrance to that vanished pulse of time. "The moving finger writes, and having writ"--There is a certain kind of door-shutting that will come to us all. The kind of door-shutting that is done very quietly, with the sharp click of the latch to break the stillness. They will think then, one hopes, of our unfulfilled decencies rather than of our pluperfected misdemeanors.Then they will go out and close the door.__________________________________知道作家名 在goole里作家名+door搜一下就可以了

狗方碧春门锁撞翻¥鄙人他极~Pet-ct的suv值大于10其实也不一定是肿瘤。只能说Ssuv越高,大小。你正在接受化疗。不要想那么多, 狗你哭肿,狗电脑洗干净衣服叫醒他%我告诉你,癌胚抗原CEA参考正常值是:0-5 ug/L,是一个广谱性肿瘤标志物,它能向人们反映出多种肿瘤的存在,对大肠癌,乳腺癌和肺癌的疗效判断,病情发展,监测和预后估计是一个较好的肿瘤标志物,但其特异性不强,灵敏度不高,对肿瘤早期诊断作用不明显.此外,结肠炎,胰腺炎,肝脏疾病,肺气肿,及支气管哮喘等也常见轻度升高.所以,单纯CEA升高不能说明什么问题,还要结合患者临床症状,和其他化验指标才能判断疾病的具体情况.以下资料供参考:癌胚抗原为消化道肿瘤的辅助诊断指标.[英文缩写]CEA[参考值]≤5ng/ml[临床意义]CEA最初发现于结肠癌和胎儿肠组织中,故名癌胚抗原.CEA升高常见于大肠癌,胰腺癌,胃癌,小细胞肺癌,乳腺癌,甲状腺髓样癌等.但吸烟,妊娠期和心血管疾病,糖尿病,非特异性结肠炎等疾病,15%~53%的病人血清CEA也会升高,所以CEA不是恶性肿瘤的特异性标志,在诊断上只有辅助价值.此外,血清CEA水平与大肠癌的分期有明确关系,越晚期的病变,CEA浓度越高.97%的健康成人血清CEA浓度在2.5ng/mI以下.原发性结肠癌患者CEA增高占45-80%.除原发性结肠癌以外,腺胰癌,胆管癌,胃癌.食道癌,腺癌,肺癌,乳腺癌和泌尿系统的肿瘤阳性率也很高,一般在50-70%.良性肿瘤,炎症和退行性疾病,如结肠息肉,溃疡性结肠炎,胰腺炎和酒精性肝硬变病人CEA也有部分升高,但远远低于恶性肿瘤,一般小于20μg/L,CEA超过20 ng/ml时往往提示有消化道肿瘤.所以测定CEA可以作为良性与恶性肿瘤的鉴别诊断依据.[要求]空腹抽取静脉血2ml,避免溶血,污染.如不能及时送检,应分离血清后置—20℃冷冻保存.胃癌癌胚抗原(CEA)癌胚抗原(CEA)是一种酸性蛋白.癌旁正常粘膜CEA含量很少或为阴性.胃癌的CEA阳性率85.58%.其中粘液腺癌及印戒细胞癌(粘液细胞癌)为100%.电镜下见CEA同时分布于癌细胞膜,及癌细胞内胞质内的蛋白合成及转运的细胞器(如核膜,内质网,高尔基器及其分泌小泡)中,提示癌细胞合成CEA增加,因此进入腺腔的CEA也增加,由于CEA位于围绕细胞膜的糖包膜易于释入周围体液中,故体液及胃液中CEA浓度高于血清.癌细胞质内CEA含量较多的原因与癌细胞CEA合成增加及CEA排出 受阻有关.当癌细胞变性坏死时,细胞内膜结构受损破裂,CEA可出现在胞质的基质内.免疫电镜观察,见粘液细胞癌CEA分布在整个细胞膜和胞浆的膜结构中,CEA抗原决定基为糖蛋白,而肿瘤细胞的浸润和转移均与细胞膜糖蛋白的糖基化改变有关.另外粘液细胞癌还能分泌释放大量蛋白水解酶,破坏 癌细胞钙桥,溶解癌巢周围软组织.因此胃印戒细胞癌侵袭力强,转移率高.
