The main aberrations of the euchromosomes was chromosome gain, including trisome, tetrasome, and polysome. The gain rates of the four euchromo-some were 84.9%, 77.5%, 63.7% and 83.2%, and the frequencies of polysome for each euchromosome were 24.6%, 34.9%, 23.4% and 31.7%, respectively. Loss of chromosome Y was observed in 61.2% of male patients. The combination of the four chromosome probes 3, 8, 10 and 20 detected 74.5% of ESCC and the combination of 3, 8, 20 and Y detected 85.0%.

发现所测常染色体在食管癌组织中均存在较高的数目畸变率，主要表现为染色体增益，包括三体、四体及多体。4条常染色体3、8、10和20号染色体增益率分别为84.9%、77.5%、63.7%和83.2%，其中多体率各为24.6%、34.9%、23.4%和31.7%。Y染色体在61.2%的男性患者表现缺失。3、8、10和20号探针联合检测食管癌的阳性率为74.5%， 3、8、20和Y染色体探针联合检测男性食管癌的阳性率为85.0%。

Genetic diversity and phylogenetic relationship in goldfish were examined using mitochondrial D-Loop partial sequences at eight representative varieties of goldfishes and wild crucian carp. The eight representative varieties were Red Common Goldfish, Red Fantail, White Oranda with Red Carp, White Pearlscale, Red Tigerhead, Black Moor, Red Moor with Butterfly Tail and Red Bubble-eye with Dorsal Fin. 699 base-pair nucleotide sequences of Mitochondrial D-Loop were examined and analyzed for genetic polymorphism, Sequences data showed that all 129 sequences were grouped into 17 haplotypes. Nine representative varieties shared same haplotype. Five representative varieties of goldfishes had haplotypes respectively.

采用PCR技术扩增了红草金鱼，红文鱼，红顶白高头，白珍珠，红狮头，红龙睛蝶尾，墨龙睛，红水泡八个品种金鱼和野生鲫线粒体DNA的D-Loop区部分序列，PCR产物经纯化、测序、同源序列比对后获得长度为699bp的核苷酸序列，在129个样本中共检测到了17个单倍型，9个品种共享1种单倍型，5个品种的金鱼(BM， MB， WR， RF， RC)检测到各自独有的单倍型。
