摘要
人多瘤病毒(John Cunningham Virus,JCV)是广泛存在于人体内的一种多瘤病毒,最近二十年,国外研究显示JCV感染与多种神经系统及消化系统肿瘤高度相关,而JCV感染与妇科肿瘤关系的研究还鲜有报道。本研究在建立JCV核酸检测方法及规程的基础上,收集子宫肌瘤(98例)、子宫颈癌(84例)、子宫内膜癌(40例)、卵巢肿瘤(72例)患者临床资料、活检组织及血和尿样。运用PCR技术对上述患者活检样本及血、尿样本实施人乳头瘤病毒、单纯疱疹病毒Ⅱ型、人类疱疹病毒(Estein-barr virus,EBV)、巨细胞病毒和多瘤病毒JCV及BKV(B.K.virus,BKV)核酸检测。子宫颈癌高度相关人乳头瘤病毒在子宫颈癌组中检出率(19.0%)明显高于其它组,单纯疱疹病毒Ⅱ型、EBV及巨细胞病毒检出率几乎为0。BKV在尿样中的检出率明显高于血样及活检组织检出率,且检出率在各患者组中无显著差异。JCV检出率在血清样本及活检中几乎为0,然而,尿样中检测率均超过50%,且在子宫肌瘤患者组中高达65.3%。本研究显示JCV感染与子宫肌瘤高度相关,为子宫肌瘤的发病机理提供了新的病原学参考证据。
The JC virus is a widely infected human polyomavirus. Recent foreign researches showed that the JC virus infection is correlated with tumors of nervous system and digestive system, while, and study on the relationship between JC virus infection and gynecological tumor is seldom reported. In this study, we first establish the nucleic acid detection methods and procedures for JC virus and its highly homologous BK virus. The JC and BK viruses infection was evaluated by detect the viral DNA in samples including biopsy tissues, serum as well as urine of myoma of uterus （98 cases）, cervical cancer （84 cases）, endometrial cancer （40 cases） and ovarian tumor （72 cases） patients. The BK viral DNA positive rate was significantly higher in urine samples than that of blood and biopsy samples, and there is no significant difference of the BK viral DNA positive rate among all patient groups. The JC viral DNA positive rate is almost 0 in serum samples and biopsy, tissues, however, viral DNA positive rate is more than 50% in urine samples. In fi- broids group, the JC viral DNA positive rate is up to 65.3% which is significantly higher than that in other patients groups and healthy control. Further gynecological tumor associated viruses detection showed that only human papilloma virus infection is associated with cervical cancer, the herpes simplex virus, EB virus and cytomegalovirus infection is extremely low in our patient groups. No synergistic effect on gynecological tumor caused by viruses co-infection was observed. Our study showed that JC virus infection is highly related to the pathogenesis of uterine fibroids.
