FAM19A4基因启动子甲基化检测在宫颈癌及其癌前病变筛查的研究

宫颈癌是最常见的妇科恶性肿瘤之一。目前人乳头瘤病毒(HPV)检测及细胞学检查是宫颈癌及其癌前病变(CCPL)的主要筛查手段。由于上述传统筛查方法,仍然存在对CCPL漏诊的风险,因此寻找有效识别CCPL的特异性分子标志物,具有重要临床意义。对具有序列相似性家族19成员A4(FAM19A4)基因启动子甲基化定量检测,可有效检出CCPL组织,较传统筛查方法有较高特异度,有望成为CCPL筛查的特异性分子标志物。笔者拟就FAM19A4基因启动子甲基化定量检测,在CCPL筛查中应用的最新研究现状进行阐述,旨在为进一步推进CCPL筛查方法的开发,提供思路。     

右颌下血管周肌细胞瘤一例

患者女,48岁。因发现右颌下结节1年余,长大2个月,于2003年11月10日入院。患者入院前1年无明显诱因出现右颌下结节,约豌豆大小,不痛,未予处理。2个月前发现结节进行性长大。体检：右颌下扪及一直径2cm类圆形肿块,固定,表面光滑,边界尚清,无压痛,未扪及血管搏动。     

桡骨远端瘤段切除带血管蒂的腓骨移植重建桡腕关节

目的：探讨桡骨远端骨肿瘤切除术,吻合血管的带腓骨头腓骨近端移植修复桡骨远段缺损和重建桡腕关节的疗效。方法：17例桡骨远端骨肿瘤患者行桡骨远端切除,应用吻合血管的带腓骨近段移植修复骨缺损并重建模腕关节。移植体行简单内固定＋外固定;术后定期复查X线片,Dopplar血管超声,及腕关节功能评定。结果：随访3个月－2年,全部病例均于手术3个月后达一期骨愈合;其中1例因钢板螺丝钉动再次行内固定而愈合。评定重建腕关节功能,优12例,良3例,差2例。病灶无复发。结论：桡骨远端骨肿瘤切除后行吻合血管的带腓骨头腓骨近端移植修复骨缺损并重建腕关节。手术切除彻底,复发率低,重建后的腕关节功能良好。     

鼠牙乳头细胞核心结合因子cDNA片段的克隆与序列测定

目的 从培养大鼠牙头细胞中克隆核心结合因子（cbfal）的cDNA片段。方法 原代培养大鼠牙乳头细胞,提取培养细胞的总RNA,逆转录合成cDNA,用PCR的方法扩增cbfal基因片段。将获得的预期大小的PCR产物插入pUC18克隆载体中,转化TOP10感受态细胞,蓝白筛选白色克隆,进行体外扩增,提取质粒进行酶切鉴定,含目的插段的克隆在PE317-A自动测序仪上进行序列测定。结果 从培养的鼠牙乳头细胞提取的总RNA中成功克隆出691bp cbfal基因片段,测序结果和GenBank报道序列完全一致。结论 从鼠牙乳头细胞中成功克隆到cbfal基因片段,确切的证实了核心结合因子（cbfal）基因在鼠牙乳头细胞中的表达。

Cystoid macular edema in anterior chamber lens implantation following posterior capsule rupture

By comparing the incidence of cystoid macular edema (CME) in three groups of patients having different surgical procedures, we attempted to assess the role of vitreous loss as a risk factor for CME development. In the first group (n = 470), the surgical procedure was extracapsular cataract extraction followed by implantation of posterior chamber lens (EC-CE + PC-IOL). The second group (n = 42) had extracapsular cataract extraction which was complicated by posterior capsule rupture, and therefore anterior vitrectomy followed by implantation of anterior chamber lens had to be performed (ECCE + anterior vitrectomy + AC-IOL). In the third group (n = 22) the surgery was intracapsular cataract extraction followed by anterior chamber lens implantation (ICCE + AC-IOL). The third group was included in this follow up study to assess the role of AC-IOL as a possible causative factor for development of CME in uncomplicated cases of ICCE and AC-IOL. The difference of incidences of CME in the second and third group would therefore depend mostly on the vitreous loss. The incidence of CME diagnosed by fluorescein angiography in the first, second and third group was 1.5% (7/470), 35.7% (15/42) and 9.0% (2/22), respectively. All patients who developed CME were treated with combination of corticosteroid-antibiotic drops, dexamethasone retrobulbarly (40 mg/day) and peroral indomethacine (25 mg/day/6 weeks). This therapeutic regime resulted in only moderate improvement of visual acuity.Abbreviations AC-IOL anterior chamber intraocular lens - CME cystoid macular edema - ECCE extracapsular cataract extraction - ICCE intracapsular cataract extraction - IOL intraocular lens - PC-IOL posterior chamber intraocular lens
