ABSTRACT
【Objective】 To explore the difference of total protein (TP) content, coagulation factor VIII (FⅧ) activity and Fib content in different common plasma products, and to further provide basis for the establishment and refinement of relevant quality standards of common plasma products. 【Methods】 Samples involved in the experiment included frozen plasma and cryoprecipitated frozen plasma derived from whole blood and eukocyte-depleted whole blood. The TP content determination was carried out by biuret method. The FⅧ activity (FⅧ: C) and Fib content were determined by coagulation method. 【Results】 The TP content( g/L) in frozen plasma and cryoprecipitated frozen plasma derived from whole blood and eukocyte-depleted whole blood were 59.64±4.78 vs 58.09±4.1 vs 52.20±3.57 vs 51.89±1.50, respectively, and the FⅧ: C( %) were 109.63±43.38 vs 27.06±7.09 vs 71.83±21.64 vs 21.66±3.86,, and the Fib content (g/L) were 2.19±0.39 vs 1.30±0.24 vs 2.04±0.37 vs1.22±0.15, respectively. There was a significant difference in TP content between other common plasma products (P0.05). There was significant difference in FⅧ: C among four common plasma products (P0.05). 【Conclusion】 The TP content and FⅧ: C of common plasma products are closely related to the initial blood and preparation process. It is suggested that the quality standard of common plasma products should be further refined, and the establishment of cryoprecipitated frozen plasma relevant quality standard and clinical indications should be considered.
ABSTRACT
Objective To investigate the effect of stem cells transplantation on immune function,liver function and related indexes in the patients with end-stage liver disease(ESLD).Methods A total of 163 cases of ESLD in Nanyang Municipal Central Hospital of Affiliated Hospital of Zhengzhou University were selected and divided into 2 groups by the randomized single blind method.Eighty-one cases in the control group were given the conventional symptomatic treatment,while 82 cases in the observation group received bone marrow mesenchymal stem cell(BMSC) transplantation based on the control group.The changes of immune function,liver function,alpha fetoprotein(AFP),rate of prothrombin activity(PTA) and plasma total protein(TP) level before and after treatment were observed in the two groups.Results The immune function indexes CD3+,CD4+,CD8+,CD4+/CD8+,TP and PTA levels after treatment in the observation group were significantly higher than those before treatment and in the control group (P＜0.05),while the levels of AFP,alanine aminotransferase (ALT),aspartate aminotransferase (AST) and total bilirubin (TBIL)were lower than those before treatment in the same group and the control group(P＜0.05).There was no statistically significant difference in complication occurrence rate between the two groups(P＞0.05).Conclusion BMSC transplantation for treating ESLD can improve the immune function,improves the liver function and reduces the AFP level.
ABSTRACT
100?g/ml was(65.6?5.8)g/L and that of those patients with their VAP0.05).CONCLUSION:Blood concentration of VAP is affected by the plasma level of TP,too low TP level is likely to induce drug poison.
