目的:探讨脆性组氨酸三联体(FHIT)基因和Ki-67抗原在原发性胆囊癌、胆囊腺瘤和慢性胆囊炎组织中的表达情况.方法:应用免疫组织化学S-P法,检测51例原发性胆囊癌、15例胆囊腺瘤和12例慢性胆囊炎组织中FHIT和Ki-67的表达情况,并分析其与胆囊癌临床病理因素的关系.结果:胆囊癌组中FHIT阳性率明显低于胆囊腺瘤和慢性胆囊炎组(47.1%vs66.7%,91.7%,P<0.01),而Ki-67阳性率明显高于胆囊腺瘤和慢性胆囊炎组(82.4%vs20.0%,0,P<0.01).FHIT表达缺失不仅与胆囊癌的高分级(18.8%vs56.5%,66.7%,P=0.02)、淋巴结或远处转移(33.3%vs66.7%,P=0.019)明显相关,而且与术后生存时间减少关系密切(31.2%vs77.8%,P=0.041).Ki-67表达与胆囊癌的高分级(58.3%vs87.0%,93.8%,P=0.039)和淋巴结或远处转移(33.3%vs66.7%,P=0.037)明显相关.FHIT与Ki-67表达呈负相关(r=-0.285,P=0.043).结论:FHIT基因是胆囊癌的一个候选抑癌基因.FHIT和Ki-67在胆囊癌的发生和演化中均起着重要作用,联合检测FHIT和Ki-67的表达情况有助于临床评估胆囊癌的生物学行为和判断预后.

Dear Editor, Phenotypic drug discovery, which observes compound effects on physiology,has given way to targeting specific molecules, but has revived by using modern methods to find drugs based on therapeutic outcomes in disease models(Vincent et al., 2022). Osteoarthritis(OA) is a prevalent chronic joint disorder, primarily affecting knee joints, with osteoclast activation due to low-grade inflammation resulting in increased bone resorption and structural changes in the joint(Katz et al.,2021).
