Embodiment

[0027] In the embodiment of the present invention, the HBsAg vaccine is provided by Dalian Hanxin Biological Products Co., Ltd., and the PA-MSHA vaccine is provided by Hainan Weixi Biopharmaceutical Co., Ltd.

[0028] rhIL-12 was developed by the inventors of the present invention. Since IL-12 is a heterodimeric protein composed of two subunits, P40 and P35, through multiple pairs of disulfide bonds, the genes encoding P35 and P40 subunits are located in different on the chromosome. The P35 subunit cannot be secreted into the extracellular space alone, but the P40 subunit can be secreted into the extracellular space alone. Therefore, the key to the expression of biologically active IL-12 is the balanced expression of the two subunits in the same cell. Therefore, the constructed CHO cell line must allow the balanced expression of the two subunits of IL-12. To this end, we inserted P40cDNA and P35cDNA into two vectors with different expression efficiencies, and then co-transfec...

Abstract

The invention relates to a vaccine composite used to treat hepatitis-B, wherein it contains 10-20 mug recombined HBsAg protein vaccine, 10-20 mug recombined interleukins 12, and 0.9-1.8 million bacillus pyocyaneus, and the left is water in each unit ml. The inventive composite can activate several immunity targets as NKT, cell, NK cell, etc, to break HBV immunity resistance, rebuild cell immunity function, and restrain HBV.

Description

technical field [0001] The invention relates to a biological preparation, in particular to a therapeutic hepatitis B vaccine composition for treating chronic hepatitis B. technical background [0002] Chronic hepatitis B is one of the common infectious diseases in my country. my country is a high prevalence area of ​​hepatitis B virus (HBV). HBV infection is a serious public health problem. In 2004, the Chinese Center for Disease Control and Prevention conducted the blood sample detection results of the 2002 Nutrition and Health Survey of Chinese Residents, which showed that the prevalence rate of HBsAg in the general population in my country was as high as 9.09%. Based on this, it is speculated that there are about 120 million chronic HBV infected people in my country People, of which about 30 million cases of chronic hepatitis B. Chronic hepatitis B has brought a heavy economic burden to the country and individuals. The direct and indirect loss of chronic hepatitis B in my...
