2N gametes are the result of meiotic mutation during micro- and mega-sporogenesis that bear the sporophytic rather than the gametophytic chromosome number. This paper reviewed the genetic markers including the morphologic, cytological, isozymes and DNA markers, which have been employed in the generation, inheritance, heterozygosity and marker-assisted breeding of 2n gametes based on the frequency of large pollen grains, cytological analyses, unexpected occurrence of polyploidy progeny and the associations between parents and progenies.

文章综述了植物2n配子发生及其遗传标记研究现状，论述涉及有关形态学标记、细胞学标记、同工酶标记乃至DNA标记等遗传标记在2n配子研究中的应用，指出通过花粉形态观察、大小孢子母细胞减数分裂行为观察、杂种后代倍性鉴定以及亲子分子标记相关分析等，对2n配子发生、2n配子遗传类型与杂合性以及2n配子在育种实践中的有效性等进行研究。

Psammoma bodies are less frequently found at cytological examination from ne-needle aspiration. Their nding in cytological preparations, however, strongly suggests malignancy, in particular, papillary thyroid carcinoma, although they are an unreliable predictor of this tumor in the absence of the other typical cytological features, such as nuclear grooves,micronucleoli, and true papillae .

沙砾体是不经常从细胞学检查细针穿刺发现，虽然肿瘤在没有其他典型的细胞学特征，如核沟槽，微核仁，和真正的乳头时，他们是不可靠的预测，但是细胞学的发现强烈暗示恶性肿瘤，特别是乳头状甲状腺癌。

There is not a significant difference in these groups by one-way analysis of variance. 2 Among 51 cases with lung cancer, 7 specimens showed malignant cells in bronchial lavages, including 4 cases in central lung cancer and 3 cases in peripheral lung cancer. Concordant results were observed in 20 cases. 6 specimens showed malignant cells on cytological analysis, and NMSP was positive in at least one gene tested. 14 samples did not show malignant cells on cytological analysis, and the NMSP results were correspondingly negative. The results of cytology and NMSP were discordant in 31 samples. 30 samples were cytologically negative, but NMSP positive in one or more genes. In addition, there was one case that the cytology was positive for malignant cells, but the NMSP was negative in all of the three gene tested.

51例肺癌患者支气管灌洗液细胞学检查发现肺癌细胞7例，其中27例中心型肺癌患者4例支气管灌洗液发现肺癌细胞，24例周围型肺癌患者3例支气管灌洗液发现肺癌细胞。20例支气管灌洗液细胞学检查和过甲基化检测得到一致结论。6例支气管灌洗液发现肿瘤细胞，过甲基化分析至少一个基因阳性。14例灌洗液未发现肿瘤细胞，三个基因过甲基化分析均为阴性。31例支气管灌洗液细胞学检查和过甲基化检测得到不一致结论，30例细胞学检查为阴性，但过甲基化分析一个或一个以上基因为阳性。1例细胞学检查阳性但过甲基化分析阴性。
