[XANES study of lead speciation in duckweed].

Qixiashan lead-zinc mine of Nanjing was one of the largest lead zinc deposits in East China Its exploitation has been over 50 years, and the environmental pollution has also been increasing. The lead concentration in the local environment was high, but lead migration and toxic mechanism has not been clear. Therefore, biogeochemistry research of the lead zinc mine was carried out.

[In vivo determination of Pb in human bone by using X-ray fluorescence analysis].

The data of in vivo XRF Pb in human bone were obtained within China by using the in vivo XRF set. The K series X-ray of Pb were applied to determine the in vivo Pb concentration in tibia and calcaneus among Chinese mainland residents. For general population, the weighted average of Pb in bone was 0.

Phase II trial of gefitinib in pretreated Chinese women with advanced non-small-cell lung cancer.

A phase II clinical trial was performed to evaluate the efficacy and safety of gefitinib on pretreated Chinese female non-small-cell lung cancer (NSCLC) patients. Chinese female patients with locally advanced or metastatic NSCLC who failed at least one platinum-based chemotherapy received gefitinib monotherapy (250 mg/day) between April 2002 and January 2010. The primary endpoint was overall response rate (ORR), and secondary endpoints were overall survival (OS) and progression-free survival (PFS).

[EDXRF analysis of soil heavy metals on lead-zinc orefield].

Due to the impact of lead-zinc mining and smelting, the soil of lead-zinc orefield and nearby areas has been widely polluted. Moreover, the concentration of lead and zinc was high, and their concentration range was wide. Furthermore, the impact of overlapping interference between low concentration As and high Pb was serious, and the lack of soil standards of lead and zinc was also a problem.
