control relatives.A ratio of s/q approached1/q with Penrose' s method.Heritability of SLE was78.8%?4.45%in the first-degree relatives,58.8%?10.9%in the second-degree relatives,and39.2%?32.0%in the third-degree relatives.The weighted mean heritability was75.2%?4.12%.Conclusions SLE has characteristics of polygenic disease.Genetic factor might play an important role in the liability of SLE.

Objective:To improve the understanding of cervical papillary squamous cell carcinoma (PSCC), and to provide evidence for the diagnosis and treatment of PSCC.Methods:The clinicopathological and follow-up data of 18 patients diagnosed PSCC by preoperative cervical biopsy in Tangshan Gongren hospital were collected, the correlation of preoperative biopsy, liquid-based cells, and human papilloma virus (HPV) with postoperative pathology and prognosis was analyzed.Results:The concordance rate between preoperative biopsy and postoperative pathology was 50% (9/18). 4 patients showed the characteristic features of PSCC in their liquid-based cells of the 9 patients who were diagnosed as PSCC postoperatively (4/9), the HPV infection rate was 44.4% (4/9), the International Federation of Gynecology and Obstetrics stage were IA1-IB1, no lymph node metastasis, recurrence or death occurred in all patients.Conclusions:Cervical biopsy before operation has certain limitations in the diagnosis of PSCC, which requires a clear diagnosis by postoperative pathology. The HPV infection rate is lower, the stage is earlier and the prognosis is better in PSCC. Some patients can choose a less invasive surgical method than radical surgery.
