白细胞介素-10和肿瘤坏死因子基因多态性与湖北汉族人群胃十二指肠疾病及幽门螺杆菌感染的相关性

Objective To study the distribution of IL-10 and TNF gene polymorphisms in patients with gastroduodenal diseases in Hubei Han ethnic and their association with Helicobacter pylori (Hp) infection. Methods Six hundred and five patients with gastroduedenal diseases (196 chronic gastritis, 189 gastroduodenal ulcer and 220 gastric cancer) as well as 624 healthy controls were genotyped with PCR-RFLP method for IL-10-1082,-819,-592 and TNFα-308, lymphotoxin-α (LTα) Nco Ⅰ and AspH Ⅰ gene polymorphisms. Hp infection status was determined with ELLS& Results (1) There was significant difference of IL-10-1082 AG + GG genotype among the gastric cancer group with the non-malignant gastric diseases groups and healthy control group (P <0. 05). There was no significant difference of IL-10-592 and -819 gene polymorphisms among gastric cancer patients,non-malignant gastric disease patients and healthy controls (P>0. 05). The genotype frequencies of IL-10-819 were the same as those of IL-10-592. (2) Frequency of IL-10-1082 AG + GG genotype in gastric cancer patients with positive Hp was significantly higher than that in the other three groups (P < 0. 05). (3) Frequency of LTα Nco I AG genotype in gastric cancer patients with Hp infection was signiilcandy higher than that in Hp positive healthy controls (P < 0. 05). There were no other associations between TNFα-308, LTα Nco Ⅰ and AspH Ⅰ gene polymorphisms and Hp infection in gastroduodenal diseases. Conclusions (1) Allele AG + GG of IL-10-1082 was associated with gastric cancer in Han nationality of Hubei province. (2) IL-10-1082 AG + GG,LTct Nco ⅠAG heterozygous genotype may be associated with Hp infection in patients with gastric cancer in Han nationality of Hubei province.

胃癌患者肿瘤坏死因子基因型与其血清水平的关系

目的 研究胃癌患者肿瘤坏死因子(TNF)-α308和TNF-β252基因型与血清TNF-α、β水平的关系.方法 收集病理诊断证实的57例胃癌患者,49例来白武汉大学中南医院,8例来自湖北省肿瘤医院.同时选取年龄与性别相匹配的18名健康体检者作为对照.采用限制性片段长度多态性聚合酶链反应(PCR-RFLP)方法检测患者外周静脉血.采用ELISA方法检测57例胃癌患者及18名对照者的血清TNF-α、β水平,比较胃癌患者各TNF基因型之间血清TNF水平的差异及其与对照者血清TNF水平的差异.分析胃癌患者TNF水平与临床病理特征的关系.结果 胃癌患者总体血清TNF-α水平较对照组明显增高(中位数445×10-3 μg/L比5×10-3 μg/L,P＜0.05),而且TNF-α308和TNF-β252各基因型(TNF α308 GA基因型6例、GG基因型51例,TNF-β252 GG基因型17例,GA和AA基因型各20例)的血清TNF-α水平较对照组也明显增高(P＜0.05),但血清总体TNF-β水平与对照组比较差异无统计学意义(P＞0.05).此外,TNF α308G/TNF-β252G和TNF-α308G/TNF-β252A单倍型胃癌患者血清TNF-α水平较对照组也明显增高(P＜0.05),其增高与血清总体TNF-α水平一样,与患者年龄、淋巴结转移显著相关(P＜0.05).TNF-α308A和TNF-β252G的高危等位基因携带者的TNF β水平与吸烟史显著相关(P＜0.05).结论 胃癌患者血清TNF-α水平增高与TNF-α308和TNF-β252基因型无显著相关性.TNF- α308G/TNF-β252G和TNF-d308G/TNF- β252A单倍型胃癌患者的血清TNF-α水平增高与年龄、淋巴结转移显著相关,提示TNF基因单倍型对胃癌TNF的表达及临床类型可能具有一定的影响.     

急性髓细胞白血病伴核仁磷酸蛋白突变1例病例报告并文献复习

正急性髓系细胞白血病(acute myeloid leukemia,AML)是一种造血祖细胞自主增殖和分化受阻的异质性疾病。AML伴核仁磷酸蛋白(nucleophosmin,NPM1)突变在2008年世界卫生组织(WHO)分类中被确认为AML伴重现性遗传学异常的一类独立亚型~([1]),本例患者为AML伴NPM1突变,但因患者骨髓原始细胞胞浆中存在大量嗜天青颗粒,极易误诊为其他类型白血病,故报告其诊疗体会。

832例甲状腺结节的超声及核素扫描与病理结果对照分析

对８３２例甲状腺结节患者的术前Ｂ超及核素扫描诊断进行了分析，并与他们术后病理结果进行对照。我们认为Ｂ超在术前诊断方面优于扫描，但扫描能反应出结节有无功能，且其对自主功能性结节诊断有独到之处，另外本组分析显示多发结节病癌的发生率高于文献统计资料，提醒人们应对结节性甲状腺肿的治疗引起更多的重视。
