Amarogentin is an efficacious Chinese herbal medicine and a component of the bitter apricot kernel. It is commonly used as an expectorant and supplementary anti-cancer drug. β-Glucosidase is an enzyme that hydrolyzes the glycosidic bond between aryl and saccharide groups to release glucose. Upon their interaction, β-glucosidase catalyzes amarogentin to produce considerable amounts of hydrocyanic acid, which inhibits cytochrome C oxidase, the terminal enzyme in the mitochondrial respiration chain, and suspends adenosine triphosphate synthesis, resulting in cell death. Hydrocyanic acid is a cell-cycle-stage-nonspecific agent that kills cancer cells. Thus, β-glucosidase can be coupled with a tumor-specific monoclonal antibody. β-Glucosidase can combine with cancer-cell-surface antigens and specifically convert amarogentin to an active drug that acts on cancer cells and the surrounding antibodies to achieve a killing effect. β-Glucosidase is injected intravenously and recognizes cancer-cell-surface antigens with the help of an antibody. The prodrug amarogentin is infused after β-glucosidase has reached the target position. Coupling of cell membrane peptides with β-glucosidase allows the enzyme to penetrate capillary endothelial cells and clear extracellular deep solid tumors to kill the cells therein. The Chinese medicine amarogentin and β-glucosidase will become an important treatment for various tumors when an appropriate monoclonal antibody is developed.

OBJECTIVE:
To analyze the efficacy of cyclophosphamideplus, epirubicin, vincristine, prednisone plus etoposide and/or bleomycin, with or without rituximab (R±BEACOP) regimen in patient with poor-prognosis lymphoma.
METHODS:
A total of 89 patients, who had poor-prognosis lymphoma and received at least 1 cycle of R±BEACOP regimen during 2002 to 2012, were enrolled and analyzed by a retrospective study.
RESULTS:
The rate of complete response was 62.9% (56 patients). The efficacy of Hodgkin lymphoma (HL) and T/NK NHL was better than that of other types of lymphoma. There was no significant difference in efficacy among the patients with different age, stage or international prognosis index (IPI) (all P>0.05).
CONCLUSION
R±BEACOP regimen is effective in some patients with poor prognosis, especially in HL patients. Thus, multicenter prospective study regarding the R±BEACOP regimen needs to be done to further test its efficacy.

6.Treatment of Behcet's disease.
Yonsei Medical Journal 1997;38(6):401-410
Behcet's disease is characterized with multifactorial etiopathogenesis and multiclinical pictures. The treatment of patients with Behcet's disease is based on the severity of illness, and the most appropriate management of Behcet's disease requires a multidisciplinary approach. Although various therapeutic modalities have been employed for Behcet's disease, treatment is far from satisfactory. Treatment of Behcet's disease includes local, systemic, or surgical therapies. Limited success has been found with colchicine, azathioprine, indomethacin, cyclophosphamide, chlorambucil, levamisole, transfer factor, fibrinolytic therapy, and systemic corticosteroid. New therapeutic approaches have been introduced for Behcet's disease using cyclosporine, thalidomide, interferon, acyclovir, high-dose corticosteroids or cyclophosphamide pulse therapy, and FK 506. We suggest that therapeutic agents should be selected after thorough evaluation of the immune state of each patient by using various tests and by determining any aggravating or provoking factors involved. In general, a combination-agent regimen is more effective than a single-agent regimen. Early diagnosis and proper treatment can inhibit or at lease slow the progress of the disease remarkably.

In the recent years, researches on drugs for prostate cancer have received more attention than ever before. This article reviews the mechanism and efficacy of such prostate cancer drugs as bicalutamide, medroxyprogesterone acetate, megestrol acetate, flutamide and so on, as well as the clinical data and clinical uses of calcitriol analogue EB1089, SR233377, etc.

Blood products are those biologicals derived from plasma or obtained by recombinant technologies. This overview covers the characteristics and classification of plasma proteins, the current status of products (albumin, immunoglobulins, coagulation factors and microcontent proteins), as well as the likely trends in the near future. Human serum albumin is one of the earliest, safest and most widely used proteins in the pharmaceutical field. The approval and development of high-purity plasma albumin, recombinant human albumin and HSA fusion proteins provide a favorable prospect for the therapeutic protein. Normal immunoglobulin contains antibodies to all the micro-organisms prevalent in the donor population. The IMIG is relatively simple to prepare and use, and the side effects are acceptable; IVIG is used mainly to treat patients with primary immunodeficiency syndromes; SCIG preparations can be used in selecting suitable patients for home therapy and have occurred fewer adverse systemic reactions; specific immunoglobulins contain concentrations of antibody to an individual organism or toxin at a higher titer than normal immunoglobulin and can not be replaced in clinical use. The plasma-derived or recombinant coagulation factors are used to treat the patients with congenital or acquired factor deficiency. The products such as Fibrinogen, FVII, FVIII, von Willebrand complex, FIX/PCC, FXI, FXIII and so on, have been widely used and proved to be effective. The development of recombinant FVIIa is now as a good bypassing product to haemophilia with inhibitors. The Fibrinogen and thrombin play a very important role in surgery hemostasis. Moreover, microcontent proteins including protein C, antithrombin, alpha 1-AT, tPA have been licensed and used in clinical treatment; a number of other small field proteins are under produced research or pre-clinical investment. The ongoing development of new recombinant plasma proteins is providing alternatives for patients, but the distinct position and the potential impact of plasma-derived preparations are unique, furthermore the development of new plasma protein is still a hot spot in global pharmaceutics. Nowadays, a relative difference exists in the development of blood products between our nation and developed countries, so the domestic manufacturers are faced with chances and challenges.
