RESULTS Duodenal ulcer was the first cause of upper gastrointestinal hemorrhage. Gastric ulcer, cirrhosis, Mallory-Weiss syndrome or acute gastric mucous lesion was the second cause of the illness alternatively. The rate of endoscopy and emergent endoscopy has been going up year after year and got up to 80% in 1998. Bleeding and active hemorrhage, respectively were found in 24.3% and 14.9% of the patients underwent endoscopy before medication. Endoscopic hemostasis was performed in 108 patients by spraying hemostatics and a good response was achieved subsequently. Hemostatics were mainly cimetidine and yunnan baiyao before 1994. Reptilase, pPI, famotidine and ranitidine were used increasingly while cimetidine and yunnan baiyao were used decreasingly. Octreotide was used in patients with cirrhosis commonly. The length of hospital stay and the period from admission to bleeding cease tended to be shorter year by year, but the reduction rate was small. The uses of ranitidine, famotidine, pPI, reptilase, octreotide, early endoscopy and endoscopic therapy may play a role in improving the therapeutic effect of hemostasis, reducing the hospitalization and the mortality.
结果 十二指肠球部溃疡是历年上消化道出血的首要原因,胃溃疡、肝硬变、Mallory -Weiss综合征、急性胃粘膜病变则交替成为第2位出血原因;内镜诊断率和急诊内镜率逐年提高,1998年达到80%,内镜下见出血者占内镜检查的24.3%,而见到活动性出血者仅占内镜检查者的14.9%;内镜下止血108例次,成功率100%;1994年前治疗药物主要为云南白药和甲氰咪胍,之后,随着立止血、质子泵抑制剂、法莫替丁、雷尼替丁等药物使用的逐渐增多,前二者的使用逐渐减少,善得定多用于肝硬变出血;住院天数和止血天数呈逐年下降的趋势,但幅度微小;雷尼替丁、法莫替丁、PPI、立止血、善得定的使用以及及时的内镜检查和内镜下治疗在提高止血效果、缩短住院天数、降低死亡率方面可能起到了一定作用。

RESULTS: In this series, 6 cases showed hematemesis, 2 showed melena and 5 showed both symptoms. All cases underwent endoscopic examination after being hospitalized; 11 cases received a positive diagnosis by endoscopy (11/13, 85%), the success rate of first endoscopic therapy was 91%(10/11), and 4 cases were treated by laparotomic surgery (4/13, 31%). Among them, definitive surgery was performed under the guidance of endoscopic hemoclipping in 2 patients who failed to be treated by endoscopy. In another 2 cases, diagnosis was missed by endoscopy and definite diagnosis was made only following exploratory operation or on the basis of pathology after the operation.

METHODS: 40 cases were classified stage IV with lumen obstruction after they failed all other treatment regimens. PDT was performed witn 630nm light delivered through cylinder diffusing tip quartz fibers passed through the biopsy channel of a flexible endoscope 48h after intravenous injection of the photosensitizer photofrin. PDT endoscopy was repeated and necrotic tissue was mechanically removed and, if necessary, that site or other new sites were treated after 48 hours. Two days after this another endoscopy was performed and the necrotic tissue was mechanically removed. Endoscopy was repeated one month after PDT and periodically thereafter as needed to re-treat symptomatic residual tumor.
40例肿瘤患者均属于IV期,所有患者都经过化疗、放疗或其他方法治疗无法解除腔道梗阻或不完全梗阻,部分完全梗阻患者结合其他治疗手段解除梗阻,光敏剂为photofrin,按2mg/kg体重静脉滴注,48小时后经内镜导入光导纤维给以630nm(DIOMED半导体激光治疗机)的激光照射,2天后经内镜清除坏死组织并对原有病灶和新发现病灶给以复照,之后根据具体情况给患者的病灶部位清除坏死组织。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
