OBJECTIVE To develop a rapid, sensitive and specific real-time PCR assay for the detection of WU polyomavirus.METHODS The VP2 gene of WU polyomavirus was selected as target gene.The specific primers and TaqMan probes according to the principle of the TaqMan real-time PCR were designed and synthesized,we optimized the PCR reaction,and detected 394 clinical samples.The sensitivity,specificity,reproducibility and dynamic range of the methods were determined.RESULTS The real-time PCR was established and applied successfully to detect the WU polyomavirus.The real-time PCR assay showed excellent linearity between the log of target input and CT value,demonstrating that the assay had a dynamic range of at least 8 logs between 1.0?100 and 1.0?107 copies;the coefficient of variation of intra-assay and inter-assay was less than 5%.Among these 394 specimens,3(0.76%) were positive for WU polyomavirus.CONCLUSIONS The real-time TaqMan PCR is a rapid,specific and sensitive method to detect WU polyomavirus.It can be used in screening large numbers of samples at the same time and establish the solid technological base for clinical diagnosis and epidemiology study.

Objective To investigate clinical significance of soluble CD30/CD30L and CD40/CD40L system imbalance in ovarian serous tumors.Methods 40 patients of serous cystadenoma and 30 patients of serous cystadenocarcinoma were selected,and 40 age-and weight-matched healthy women were also recruited as the control group.Peripheral venous blood (3 ml) of the healthy control and patients with ovarian serous tumors before surgery and 7 days after surgery were collected.After separation of serum,ELISA was used to detect levels of sCD30,sCD30L,sCD40 and sCD40L.Results Compared to the control group,levels of sCD30,sCD30L,sCD40 and sCD40L in both serous cystadenoma and serous cystadenocarcinoma groups were significantly in creased (P＜0.05).And in those serous cystadenocarcinoma group,levels of such soluble proteins were much higher than in serous cystadenoma group (P＜0.05).7 days after surgery,levels of such soluble proteins were significantly decreased in both serous cystadenoma and serous cystadenocarcinoma groups (P＜0.05).Conclusion Detection of serum sCD30/sCD30L and sCD40/sCD40L is possible to have a certain guiding significance to early diagnosis of ovarian tumors and the prognosis of patients.

OBJECTIVE: To summarize pseudocyst of auricle governor square included surgical curative effect, the advantages of the analysis of the operation. METHOD: The governor of the central square in auricle pseudocyst incision, 56 cases were retrospectively analyzed clinical data, surgical curative effect and advantages were summarized. RESULT: Adopt the auricle pseudocyst governor of the central square of incision, postoperative follow-up of 6 months did not relapse. CONCLUSION Rectangle window method effective method of treating pseudocyst of auricle, able to cure pseudocyst of auricle, is a kind of simple, practical, and value in the basic-level hospital surgical method.
