The cytogenetics of the biopsies from human nasopharyngeal carcinoma (NPC) has been investigated by chromosome G-banding technique. Chromosome preparations were made directly from 28 patients with NPC. The higher frequency in the gains of chromosome No. 19 and the losses of No. 14, 22, 3, 15 indicated non-random change in numerical aberration of chromosomes. The structural aberration of chromosomes mainly focused on several chromosomes of No. 1, 2, 3, 5, 7, 12 and 14, in which the frequency involving No....

The cytogenetics of the biopsies from human nasopharyngeal carcinoma (NPC) has been investigated by chromosome G-banding technique. Chromosome preparations were made directly from 28 patients with NPC. The higher frequency in the gains of chromosome No. 19 and the losses of No. 14, 22, 3, 15 indicated non-random change in numerical aberration of chromosomes. The structural aberration of chromosomes mainly focused on several chromosomes of No. 1, 2, 3, 5, 7, 12 and 14, in which the frequency involving No. 1 was the highest. Seven marker chromosomes: Iq-, 2q+, 3q-, 7q-, 12q - large subacrocentrie chrofosome and large chromosome involving No. 3 were found in NPC. 1q- was the most common in seven markers as was observed in 22 patients. The breakpoint of No. 1 was at 1q21-25 or 1q32. Three marker chromosomes previously found in NPC biopsies in our laboratory have been observed repeatedly. There-suits by G-banding analysis show that the formation of giant group A chromosome was not consistent and at least there were several origins, mainly concerned with rearrangement between chromosomes No. 1, 2, 3 or 5.

采用直接法制备28例鼻咽癌活检组织的染色体标本进行G带分析。结果表明,鼻咽癌染色体畸变具有类型广泛、畸变率高等特点。14、22、3及15号染色体丢失和额外19号的出现频率较高反映了染色体数目畸变的非随机性。染色体结构畸变主要集中在1、2、3、5、7、12和14号染色体上,其中以1号受累最为突出。在发现的7种标记染色体中1q-的出现频率最高。1q断裂的热点分别在1q21—1q25和1q32。此外,过去在鼻咽癌活检组织中发现的3种异常染色体本实验均重复见到。显带分析结果表明,“巨A”的形成有多种来源,主要由A、B组染色体参与的易位和重组所形成。

An intelligent pattern preparation system is presented in this paper, Its hardware is introduced briefly. The system can be used to prepare not only patterns for jacquard but also that of printing textile. Its feature of pattern design is that the input contours of source materials are extracted first, then, pressed on equal slope by a computer, and stored in its reservoir. The system creates patterns automaucally by means of a restrictive-random change method according to a mathematical model. After technological processing, the patterns created are output for making pattern carriers.
