[Conversion Characterizations of Sulfate Ion and Nitrate Ion in Particulate Matter from Coal-fired Power Plants].

The particulate matter emitted from coal-fired power plants includes condensable particulate matter(CPM) and filterable particulate matter(FPM). By analyzing the concentration of SOand NO components of CPM and FPM in the inlet/outlet of wet flue gas desulfurization(WFGD) and the outlet of wet electrostatic precipitator(WESP) from 7 ultra-low emission coal-fired power plants, the variation laws and transformation characteristics were investigated. The results showed that the concentration of SO and NO of CPM decreased after WFGD, with reduction rates of 43.

[Conversion Characteristics of Combustible Particles from Coal-fired Flue Gas in WFGD and WESP].

Monitoring of condensable particulate matter (CPM) emitted from stationary pollution sources has often been neglected. To reduce the emission of CPM, it is necessary to study its transformation rules in flue-gas cleaning devices. The results show that the wet flue gas desulfurization (WFGD) and wet electrostatic precipitator (WESP) have a good synergistic effect on the removal of CPM.

[Poisoning effect of Ca depositing over Mn-Ce/TiO2 catalyst for low-temperature selective catalytic reduction of NO by NH3].

Calcium carbonate (CaCO3), calcium sulfate (CaSO4), and calcium chloride (CaCl2) were chosen as the precursors to prepare the Ca salts deposited Mn-Ce/TiO2 catalysts through an impregnation method. The influence of Ca on the performance of the Mn-Ce/TiO2 catalyst for low-temperature selective catalytic reduction of NO by NH3 was investigated. Experimental results showed that Ca salts had negative effects on the activity of Mn-Ce/TiO2 and the precursors of Ca salts also affected the catalytic activity.

[TPX2 expression and its significance in squamous cell carcinoma of lung].

Objective: To study the expression of targeting protein for Xklp2 (TPX2) and its significance in squamous cell carcinoma (SCC) of the lung.

Method: Two SCC cell lines and 4 immortalized bronchial epithelial cell lines (as a precancerous model) were examined by Western blot for TPX2 expression. Reverse transcription-polymerase chain reaction analysis for TPX2 was also performed using tumor tissues from 21 patients with SCC of the lung.

[Clinical features and prognosis of multiple primary tumors of lung combined with other organs--report of 281 cases].

Background & Objective: Along with the progress of tumor diagnosis, the detection of multiple primary tumors (MPT) of the lung combined with other organs is increasing, but their clinical features and prognosis are unclear yet. This study was to investigate clinical features and prognosis of MPT of the lung combined with other organs.

Methods: Of the 281 patients with MPT of the lung combined with other organs, treated in our hospital from Jan.
