本文收集泰安地区下港乡和肥城县柳林村两个病区145例克汀病患者的家庭分布资料,采用 G 统计量齐性检验和二项分布拟合检验方法,作家庭聚集性研究,同时做了9例地克病人的染色体检查,发现两病区均有家庭聚集性存在,并与家庭中病人多少有关。提出调查单位较小,结果不一致时应以 G 统计量结果为准。地克病家庭聚集性的存在,提示有与遗传因素或血缘有关的可能,统计分析结果并不证实一定有遗传关系,本文地克病人染色体检查均属正常,不能证实有遗传因素。但也不能排除遗传的影响,作染色体检查仅能初步排除染色体遗传病。
This article collected family distribution data of 145 patients with cretinism in Xiagang Township of Tai’an and Liulin Village in Feicheng County. Using the G-statistic homogeneity test and binomial distribution fitting test, Done 9 cases of chromosomes of patients and found that both families have clustered presence, and the number of patients in the family. Proposed small survey units, the results should be inconsistent G statistics results shall prevail. Dick’s family aggregation exists, suggesting that genetic factors or blood may be related to the possibility of statistical analysis does not confirm that there must be genetic relationship, this article grams of patients with chromosomal examination are normal, can not be confirmed genetic factors. But we can not rule out the genetic effects of chromosomal examination can only initially ruled out genetic disorders of chromosomes.
