①Location of WD gene in Ch inese: Using pairwise linkage analysis and multipoint linkage analysis method, w e constructed a genetic map of DNA markers within D13q14.2-3 which refined the location of WD gene by restriction fragment length polymorphism and microsatellite polymorphism analysis;②Screen for mutations of WD gene in Chinese people: we detected the structure of 21 exons of WD ge ne in 45 patients from 39 pedigrees by PCR-SSCP(Single strand conformation poly morphism) and PCR-DNA sequencing technology, found a new mutation in exon 5 and nuclcotide sequence analysis showed it is a T insertion. We also conformed the Arg778Leu in exon 8, the highest frequence mutation point in Chinese people, wit h mutation rate 22.8%in total;③Carrier detection and presymptomatic diagnosi s of WD: Based on DNA recombination technology, we peformed successfully the gen e diagnosis in all individuals of 79 families with WD and built up a helpful spe cific enzyme cut method (PCR-Msp1) to detect the carrier and presympomatic patients in Chinese pe ople with WD.

①WD的基因定位研究：通过RFLP及微卫星多态性分析，应用两位点及多位点连锁软件，建立了中国人WD基因在D13q14.2-3区域的精细遗传连锁图谱，从而首次对中国人WD基因进行了精确定位；②WD基因突变研究：应用PCR-SSCP及DNA测序技术，对39个家系45名WD患者进行该致病基因的21个外显子突变筛选，发现WD基因5号外显子存在新的T插入突变，并证实中国人WD基因的突变热点为8号外显子，突变形式为Arg778Leu，其频率为22.8%；③WD的症状前诊断和杂合子检出：应用DNA重组技术对79个家系进行基因诊断，成功地进行了WD的症状前诊断和杂合子检出，并建立了WD的基因筛选的PCR-Msp 1酶切方法。

Methods The presence and localization of the dilatant nasal mucosa capillaries in proband was determined by endoscope of nasal cavity; clinical diagnosis of HHT was established by obtaining the patient's bleeding history, family history, and observation of bleeding sites.

完善血常规、肝肾功能和胸片、腹部B超、血氧饱和度等检查；进行出凝血时间、血块回缩率、血小板聚集功能等检查；对与先证者有血缘关系的家系成员进行胸片、腹部B超、血氧饱和度检查，以排除和诊断HHT，绘制HHT遗传系谱图。

The "stemma equimultiple random select cross method" and "random mating method" were used to propagate offspring population of Langshan chicken. For each population, the pedigree of individuals were ascended up to 5 generations. Then, their generation increment of inbreeding coefficient was caculated using the regression slope rate.

以狼山鸡为素材，利用"家系等量随机选配法"和"随机交配法"2种保种方法进行继代繁殖鸡群，每个保种群每个世代的鸡只均逐只编制往上追溯5代的系谱图，利用回归斜率分析方法计算世代增量。

Methods The polymorphisms of eight STR loci in 87 normal persons and 8 haemophilia B families were assayed by PCR and genescan, and the linkage relations were analysed.

应用PCR和Genescan等方法分别检测 87名正常人和 8个血友病B家系(35人)的 8个STR位点的多态性，并进行家系遗传连锁分析。

Objectives To search for mutations in NOTCH3 gene in four Chinese families with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy.

方法对 4个经临床和病理检查证实的CADASIL家系中的先证者作NOTCH3基因编码区外显子 1～ 12的聚合酶链反应和DNA测序，对家系 2和 4中的部分亲属也作了同样的检查。

Methods Using polymerase chain reaction-single strand conformation polymorphism, all the 41 exons of TSC2 gene were analyzed in 4 TSC cases (include 1 suspect case) from one family and 1 sporadic TSC case, and compared with the kin familial controls and kinless normal controls.

采用聚合酶链反应－单链构象多态性技术，对TSC一家系4例TSC患者（其中1例疑似）、1例散发性TSC患者外周血TSC2的41个外显子进行检测，并与家系中健康对照组和无血缘关系健康对照组进行比较。

Where we love is home, home that our feet may leave, but notour hearts.

家是我们情之所系的地方，虽只身在外，但心系家园。

The results showed that highly significant differences were observed between the two nitrogen treatments and also among family lines in the 4 nutrient contents. Applicating nitrogen may increase the contents of CP and CF in stalk, but decrease the contents of ADF and NDF. The variance segregation of stalk nutrients of F2∶4 lines were in normal distributions and with over parent segregation in some degree. The sensitivity to nitrogen fertilization varied with maize genotypes.

结果表明，两种氮肥处理之间以及不同家系之间各营养成分含量差异均达极显著水平；增施氮肥有利于提高秸秆的粗蛋白和粗脂肪的含量，降低酸性洗涤纤维和中性洗涤纤维的含量；两种氮水平条件下，不同家系之间秸秆各主要营养成分含量的变异性分离均符合正态分布，并存在不同程度的双向超亲分离；不同基因型的玉米对氮素的敏感性各异。
