【Objective】 To study the application effect of gel adsorbent tank in the production of human prothrombin complex concentrate(PCC). 【Methods】 Six batches of PCC were produced from 1000 L cryoprecipitated plasma, using the same gel twice for adsorption within the tank.The number of gel repeated application was examined by retrospective confirmation, and the adsorption rate, specific activity and residue of finished virus inactivation reagent were determined before and after adsorption. 【Results】 All 6 batches of PPC, produced by the same gel, satisfied quality criteria. Both PPC solution and the gel presented good color. The average activities of coagulation Factors Ⅱ, Ⅶ, Ⅸ and Ⅹ of six batches of PCC were 118.2%, 157.0%, 140.5% and 176.8%, respectively. The The adsorption capacity of coagulation factor Ⅱ, Ⅸ and Ⅹ were both 100% in the first and second adsorption, while coagulation factor Ⅶ were 75% and 81%, respectively. The average specific activity of coagulation factor Ⅸ was 0.7 IU/mg. The average residues of polysorbate 80 and tributyl phosphate products were 0 μg/mL and 33 μg/mL, respectively. The same batch of gel can be repeatedly used up to 6 times during the PCC process. 【Conclusion】 The gel adsorption tank presents good application value in the production of PCC, which can realize process amplification and automatic control.

Objective To assess the value of the clinical application of two dimensions reconstruction and surface shaded display (SSD) with multiple slices spiral CT in diagnosis of peripheral pulmonary carcinoma .Methods Peripheral pulmonary carcinomas in 35 cases were scanned by multiple slices spiral CT. The source images of CT were reconstructed by two dimensions reconstruction and surface shaded display (SSD) techniques.Results The images of two dimensions reconstruction could show the internal structure of lesions,lobulated sign burr sign,the vessels surrounding the focus,and the relation between focus and pleural as well as mediastina,but the relation of tumor and the organs surrounding the tumor could be showed not stereoscopically and directly.The images of SSD could not only reveal the relation between focus and surrounding organs in different dirctions but also revealed the features of pulmonary carcinoma stereoscopically and directly.Conclusion It is valuable for diagnosis of peripheral pulmonary carcinoma that application of SSD based on the images of two dimensions reconstruction.

OBJECTIVETo explore the effect of Dahuang Zhechong Pill (DHZCP) on transforming growth factor-beta 1 (TGF-beta 1) in rats hepatic stellate cells.

METHODSLiver fibrosis model rats were induced by CCl4 compound factor, and treated with DHZCP in three different dosages (ordinary, double and triple) separately. TGF-beta 1 and alpha-smooth muscle actin (alpha-SMA) synthesis expression, and grades of fibrosis were observed.

RESULTSTGF-beta 1 and alpha-SMA expression in the group treated with ordinary dose of DHZCP was insignificantly different from those in the control group (P > 0.05), but the expression attenuated significantly after treatment with double or triple dose of DHZCP in the portal area and discontinuous fibrous septum (P < 0.05, P < 0.01).

CONCLUSIONDHZCP of larger dosage could inhibit the hepatic stellate cells proliferation and secretion of TGF-beta 1, and reduce the genesis of collagen, so as to weaken the auto-secretion amplifying response of the cells, which might be one of the chief mechanisms of DHZCP in antagonizing liver fibrosis.
