Sodium chromate solubility is determined in the range of NaOH concentrations from 450 to 810 g/L andsolution temperatUres from 3. to 110℃. The optimized conditions to separate sodium chromate from NaOH inleached solution are resolved. It is first found the method to efficiently separate sbdium chromate from NaOH andsodium altuninate in crude sodium chromate. Bench-scale studies on the separating are performed. Finally, goodseparation results are achieved.

This paper presents a global stereo sparse matching technique based on graph cut theory to obtain accurate correspondence of stereo point pair in vision measurement ***, in order to obtain accurate location of feature points, a new multi-scale corner detection algorithm is proposed where wavelet coefficients are used to determine feature points by calculating an auto-correlation matrix.A sparse graph is constructed based on the feature points according to the graph cut ***, the feature point correspondence problem is transformed into a labeling problem in the sparse graph which can be solved by energy ***-scale analysis is utilized to improve the precision of matching *** was found that the use of sparse feature points in the construction of the graph can lead to both a simple graph structure and a reduced computational *** was also found that node labeling in the graph can be performed using fewer disparity values instead of all disparity *** experimental results show that the new global stereo sparse matching technique can obtain more accurate results than the existing techniques.

In order to investigate the relationship between the VEGF level and the counts of dendritic cells （DCs） in peripheral blood of patients with hepatocellular carcinoma （HCC） before and after transcatheter arterial chemoembolization （TACE）, the peripheral blood was obtained from 3. patients with HCC who treated by TACE. The blood was obtained on the day before TACE, the first day, the 7th day and the 15th day after TACE respectively. The counts of DCs were quantified by flow cytometry. The plasma VEGF level was measured by ELESA kit. It was shown after TACE, the counts of DCs in peripheral blood were decreased significantly （P〈0.05）, and the VEGF level in peripheral blood was increased significantly （P〈0.05）. The counts of DCs in peripheral blood had an inverse correlation with the plasma VEGF level （r=-0.57, P〈0.05） after TACE. It was concluded that in patients with HCC after TACE, the increased plasma VEGF level appeared to have the effect to suppress the maturation of DCs, which may contribute to reduction of the body＇s anti-tumor immunity effect, with a consequence of recur and metastasis of tumor.
