AIM: To find the susceptible or resistant genes of H pylori infectionin Bai-ethnic children of Kunming,and to explore the immunogenetic mechanism of H pylori infection.

目的：探讨昆明白族儿童幽门螺杆菌(Helicobacter pylori，H pylori)感染与人类白细胞抗原-DQA1(HLA-DQA1)等位基因的相关性，寻找是否存在与H pylori感染相关的易感基因或抵抗基因，从免疫学的角度探讨H pylori感染的免疫遗传机制。

The results suggest that the average level of serum lipids in the same apoE phenotype patients with gallstones is higher than that in controls, and the different apoE phenotypes patients with gallstones have different characteristics of dyslipidemia.ε2 allele is probably one of the dangerous factor in the lithogenesis of cholecystolithiasis.

由此表明：同一apoE基因表型胆囊结石患者的血脂质变化比非结石者突出，不同apoE基因表型的胆囊结石患者有不同的血脂变化特征，ε2等位基因可能是国人胆囊结石病的一个高危易患因子。

The topology of NJ tree indicated that local population of wild boar are polyphyletic, and individuals from same local population are not monophyletic, and low confidence level was obtained.

根据共享等位基因距离构建的个体水平系统发生树也表明，中国大陆地区野猪的系统发生是复系发生，同一地方种群没有出现明显的单系群；系统发生树各分支长度几乎相等，未得到高的置信度支持。

The result indicates that there are one dominant and one recessive complementary gene that are effective against the Indian race 2E16. However, the monosomic analysis results indicated there was one resistant gene to the Indian race 2E16 and the gene was located on chromosome 3B. The current study shows that it is different from the known genes.

采用常规杂交分析方法，对铭贤169与阿夫杂交的F_1、F_2、BC_1代及其亲本进行抗性鉴定和统计分析，结果表明，阿夫对2E16菌系的抗性至少由1对显性抗条锈基因控制；通过单体分析将阿夫抗2E16菌系的1对显性基因定位在3B染色体上，等位性分析表明该基因不同于目前的已知基因。

The first level cache is split caches : instruction cache and data cache, each of which is single-cycle cache with direct-mapped organization. The second level cache is a hybrid and multicycle cache with two-way skewed-associative organization.

NRS4000是一个32位的嵌入式RISC产品，时钟频率为20MHz，采用5级流水技术，实现了面向寄存器的指令集（共128条指令），支持了寄存器窗口切换和基于优先级的中断、故障、跟踪、通信等功能，是一个完整的微处理器系统。

Objective: To explore the relationship between the genetic instability of microsatellite and the evolution of chronic myelogenous leukemia.

研究表明，许多肿瘤的发生和发展与微卫星DNAs的遗传不稳定性即基因组微卫星的不稳定性和染色体等位基因微卫星序列的杂合性缺失有关［1］。

We have identified a chick homolog gene, cAxin2, which is expressed in the otic cup beginning at stage HH14+ and exhibits a dynamic expression pattern during formation and further differentiation of the otic v.

我们发现了一个鸡的等位基因cAxin2，于HH-14+期，它初始表达在发育内耳的耳杯中，并在内耳的形成及进一步耳囊的分化过程中显示了一个动态的表达方式。

The population genetic diversity of Pteris vittata from Nanning area, including Nanning City, Wuming County, Longan County, was studied by allozyme electrophoresis method.

本文采用等位酶电泳技术，研究了南宁地区的南宁市、武鸣县和隆安县3个不同的生态环境的野生蜈蚣蕨居群的遗传多样性。

All the LOH on 〓 and 〓 was observed in invasive ductal carcino- ma, carcinoma simplex, medulary carcinoma and scirrhous carcino- ma, no deletions at these sites were observed in any invasive lobular carcinoma and others. These results imply an etiological difference.P53 gene is a hot point gene in the occurrence and development of breast, cancer. PCR-SSCP analysis was performed to detect P53 gene point mutation in the region between exon 5 and 8, 5 of 12 (41. 6%) stage I breast cancer patients contain mutation of P53, 3 of 5 patients were accompanied by 〓 deletion. These results suggested that point mutation and allelic loss of P53 gene are two vi- tal genetic events in earlier stage of breast tumorigenesis.

我们还发现，〓和〓位点LOH均分布在乳腺浸润性导管癌、单纯癌、髓样癌及硬癌中，在浸润性小叶癌和某些特殊类型乳腺癌中全部为LOH阴性，上述位点LOH可能与某些组织学类型乳腺癌的发生有关。P53基因是乳腺癌形成过程中的一个热点基因，本研究对12例Ⅰ期乳腺癌组织标本中P53基因热点区域第5、6、7、8外显子点突变进行了测定，发现41.6％（5／12）的病人有P53基因一个或多个点突变，其中3例同时伴有〓位点LOH，表明P53基因点突变和等位基因缺失是发生在乳腺癌形成早期的一个重要遗传学事件。

Fibrous hydrous zirconia, spinnable hydrous zirconia chelated by acetylacctone and modifiedhydrous zirconia were synthesized from zirconium oxychlorid(ZrOCl_2·8H_2O) and then applied toprepare ZrO_2/PVA electrospinning hybrid fibers, ZrO_2/PVA continuous hybrid fiber and ZrO_2/PVPhybrid microsphere respectively. The chemical structure, properties, microstructure and formationmechanism of the corresponding materials were investigated.

论文以无机盐ZrOCl_2·8H_2O为原料，合成出纤维状的ZrO_2水合物、乙酰丙酮配位的可纺性ZrO_2水合物和正丁醇改性的ZrO_2水合物，分别与PVA和PVP杂化复合，制备出ZrO_2／PVA杂化电纺纤维、ZrO_2／PVP杂化连续纤维和ZrO_2／PVP杂化微球，并对相关材料的组成、结构、性能及形成机理等进行了深入分析和研究。
