[Clinical Value of Peripheral Blood Circulating Tumor Cells Detection in Early Cervical Infiltrating Carcinoma Screening].

Objective: To observe the difference of circulating tumor cells (CTC) in peripheral blood of patients with different degrees of cervical lesions, and to evaluate the effectiveness of CTC detection in screening early invasive cervical cancer.

Methods: From December 2015 to October 2017, 63 cases of cervicitis, low-grade and high-grade intraepithelial lesions (LSIL, HSIL) and early invasive cervical cancer were confirmed by histopathological and clinical stages in Zhongshan Boai Hospital and Zhongshan Hospital Affiliated to Zhongshan University. The immunomagnetic bead negative enrichment technique combined with immunofluorescence was used.

[Early NPC detection through serologic risk stratification and clinical follow-up of high risk subjects].

Objective: Nasopharyngeal Carcinoma (NPC) can be successfully treated by radiotherapy, if the tumor is confined to nasopharynx, but clinical onset is usually delayed to more advanced stages, when prognosis is poor. The objective is to determine efficacy of a new program for early NPC detection, which entails stratification of the NPC risk of target population according to serum levels of 3 Epstein Barr Virus (EBV) antibodies.

Method: The sera of 1373 healthy adult residents from Zhongshan were collected and analyzed in this study from Mar 16, 2007 to Dec 31, 2007.

[Content and extractability of heavy metals in cultivated soil in Fujian province].

The total and extractable contents of 7 heavy metals in cultivated soil in Fujian Province were determined. Statistical results indicated that the cultivated soil in Fujian Province was polluted by heavy metals, but different heavy metals caused different pollution levels. The extractable contents of heavy metals accounted for 10.
