Research progress of lactoferrin as drug carriers / 药学学报

Lactoferrin (Lf) is one of the food protein belonged to the innate immune system. Apart from its main biological function of binding and transport of iron ions, lactoferrin also has many other functions and properties such as antibacterial, antiviral, antiparasitic, catalytic, anti-cancer, anti-allergic and radioprotecting. Lf is usually used as additives of food and cosmetics. The research of lactoferrin has been increasingly reported, and the application of lactoferrin as a drug carrier has drawn extensive attention over the recent year. In this paper, researches of lactoferrin as drug carriers are classified and summarized in brain targeting, liver tumor targeting, lung tumor targeting and oral delivery systems according to their different characteristics.

Mongolian folk medicine--from traditional practice to scientific development / 中国中药杂志

Mongolian folk medicine, the important part of Mongolian medicine, is the main means, method and weapon of disease prevention, treatment and health care. Mongolian materia medicas are the important literatures of guiding the healthy development of the modern Mongolian medicine with a long and dazzling history. Since the founding of new China, a new history chapter of Mongolian folk medicine was opened under the attention and support from all levels of party and government. This paper intends to provide comprehensive insight into the rapid development of Mongolian folk medicine. The resources, phytochemistry, quality standard, pharmacology, dosage forms reform and production were reviewed to expound the process that Mongolian folk medicine was developed from traditional practices to scientific development

Protein and mRNA expression of CTGF, CYR61, VEGF-C and VEGFR-2 in bone marrow of leukemia patients and its correlation with clinical features / 中国实验血液学杂志

This study was aimed to investigate the mRNA and protein expression of CTGF, CYR61, VEGF-C and VEGFR-2 in bone marrow of patients with leukemia, and to analyze the role and clinical significance of these 4 factors in genesis and development of leukemia, infiltration and metastasis of leukemic cells. A total of 100 cases of newly diagnosed leukemia, 26 cases of acute leukemia in complete remission and 30 controls were enrolled in this study. The mononuclear cells of bone marrow were collected, the mRNA and protein expression levels of CTGF, CYR61, VEGF-C, VEGFR-2 in leukemia patients and controls were detected by real time PCR and Western blot, respectively. The results showed that the mRNA and protein expression levels of above mentioned 4 factors were significantly higher than those in control (P < 0.05), only CTGF mRNA expression in AL patients after complete remission showed statistical difference as compared with control (P < 0.05), but the expression of CTGF mRNA showed statistical significance in different bone marrow hyperplasia of acute leukemia (P < 0.05). The expression level of CTGF protein showed difference in different chromosome karyotypes of leukemia (P < 0.05). The expression levels of CYR61 and VEGF-C proteins showed statistical difference in different bone marrow hyperplasia of acute leukemia (P < 0.05). The expression level of CTGF, CYR61, VEGF-C mRNA and protein in CML group were higher than that in control group. The expression levels of CTGF and CYR61 protein were higher than that in control. The mRNA and protein expression levels of above-mentioned 4 factors in sex and infiltration lf leukemic cells did not show statistical significance(P < 0.05). In correlative analysis, the mRNA expressions of above mentioned 4 factors were positively correlated with bone marrow blast count(P < 0.05), the protein expression of CTGF, CYR61 and VEGF-C were positively correlated with bone marrow blast count. It is concluded that the CTGF, CYR61, VEGF-C and VEGFR-2 mRNA and protein play a role in acute leukemia. In acute leukemia (AML/ALL), the expression of above mentioned factor was high, but except VEGFR-2. Most of them were positively correlated with bone marrow blast count. Joint block of these angiogenesis-related factors is likely to play an important role in targeting treatment of leukemia.
