Objective To observe clinical efficiency of Xuanfei Bujin particles in the treatment of primary Sjogren's syndrome (PSS) and its impact on symptom score, ESR, immunoglobulin, as well as soluble intercellular adhesion molecule (sICAM-1). Methods Fifty eight cases of PSS patients were randomly divided into 38 cases of traditional Chinese medicine treatment group and 20 cases of western medicine treatment group. The symptom score, clinical efficiency, ophthalmic examination, sICAM-1, sIL-2R, ESR, immunoglobulin and other changes were observed. Results Total effective rate of Xuanfei Bujin particles treatment group was 84.21%, better than the control group. Xuanfei Bujin particles can significantly reduce dry mouth, dry eyes, and other symptoms of the main points, and improve the inspection of ophthalmology, sICAM-1. Conclusion Xuanfei Bujin particles is safe and efficient, and has certain degree in immune regulation.

Objective To investigate the effects of cell hypoxia on radio-inducible activity of early growth response gene-1 (Egr-1) promoter and its mechanisms. Methods The reporter vector of Egr-1 promoter was constructed by inserting the promoter sequence upstream the lucifearase gene in pGL3, which was then transfected into the lung adenocarcinoma A549 cell by liposome. The luciferase activity and H 2O 2 production were detected in the transfected cells exposed to doses of 2, 4, 6, 8, and 10 Gy radiation combined with the oxygen concentrations of 0.1%, 0.5%, 1%, 2.5%, and 5 %. The changes of luciferase activity in the transfected cells exposed to various concentrations of H 2O 2 were observed. Results The reporter vector of Egr-1 promoter was constructed successfully. The radio-inducible activity of Egr-1 promoter decreased significantly in the transfected cells exposed to oxygen concentration below 2.5% in a concentration-dependent manner, as compared with that in the normal control (P

0.05). Conclusions The therapeatic effect of breast-conserving therapy of stage I,and IIa breast cancer located ≥3cm of the nipple is similar to that of modified radical mastectomy. Breast-conserving therapy can gradually become the operation of first choice for stage I and IIa breast cancer.
