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.

2.Advancement in the research of growth hormone in treating pediatric burn patients.
Chinese Journal of Burns 2013;29(1):18-21
The serious and persistent hypercatabolic state caused by severe burn injury leads to weight loss, weakening of muscles, immunity decline, and delayed wound healing in injured patients. Pediatric burn patients also suffer growth retardation. How to ameliorate the persistent hypercatabolic response is what the medical professionals should concern. Recombinant human growth hormone (rhGH) can attenuate the hypercatabolic response and alleviate the growth retardation. This article reviews the researches on the use of rhGH in the treatment of burn injury in children.

OBJECTIVETo investigate the therapeutic effect of recombinant human parathyroid hormone(1-34) [rhPTH(1-34)] on osteoporosis of ovariectomized rats.
METHODSThe model of osteoporosis was formed after 3 months of ovariectomy with 6-month age of 80 rats. Another 20 rats was control of sham operation. rhPTH(1-34) was subcutaneously injected once daily with 5, 10, 20, 40 micrograms/kg for 3 months. There were 10 rats in each group. The control of therapy included Salmon Calcitonin to 10 rats and Alendronate sodium to 10 rats. The bone weight of dry and ash, bone mineral density, bone biomechanical property, trabecular area, bone mineral deposition and serum alkaline phosphatase, Ca, P and urinary Pyridinoline/creatin (Pyd/Cr) were measured after the end of therapy.
RESULTSWhen administered to animals as a single subcutaneous injection once daily, rhPTH(1-34) increased obviously bone mass, bone biomechanical property and trabecular area, as well as bone deposition compared with the animals of control group. The bone architecture was ultimately improved by rhPTH(1-34) therapy.
CONCLUSIONSRats of ovariectomized-induced osteoporosis possess obvious effect of treatment with low dose of rhPTH(1-34) administered once daily.

6.Hemophilia B replacement therapy drugs.
Chinese Journal of Biotechnology 2016;32(2):164-171
Hemophilia B is an X chromosome linked hereditary hemorrhagic disease, which is caused by the lose function mutation of factor IX (FIX), and significantly affects the patients' lifespan and life quality. The severity of hemophilia B depends on the FIX level in the plasma. By referring to the relevant literatures, we reviewed and summarized hemophilia B replacement therapies. Specifically, we focus on recombinant factor IX products on the market and those in the pipeline, especially on the long-acting factor IX drugs, to provide the basis for researches of new hemophilia B drugs.
