Molecular imprinting technique (MIT) involves the synthesis of polymer in the presence of a template to produce complementary binding sites in terms of its size, shape and functional group orientation. Such kind of polymer possesses specific recognition ability towards its template molecule. Despite the rapid development of MIT over the years, the majority of the template molecules that have been studied are small molecules, while molecular imprinting of proteins remains a significant yet challenging task due to their large size, structural flexibility and complex conformation. This review, we summarized the research findings over the past years, and discussed the nano-reinforcing materials used to prepare molecular imprinting of proteins and the perspective of these nano-reinforcing materials.

The metabonomics method was used to study the intervention effect of Psoraleae Fructus and Myristicae Semen in "Ershen pill" on the changes in serum endogenous metabolites in spleen-kidney Yang deficiency diarrhea rats before and after processing, screen out differentiated metabolites related to spleen-kidney Yang deficiency diarrhea and explore the metabolic patterns related to spleen-kidney Yang deficiency diarrhea and the processing synergy mechanism of Psoraleae Fructus and Myristicae Semen in "Ershen pill". Efforts were made to detect SOD and MDA of each group, test rat serum metabolic fingerprints in different stages by using GC-MS, analyze by PCA and PLS-DA methods and screen out potential biomarks through VIP and t test. The results revealed that "Ershen pill" could enhance the level of SOD and decrease the level of MDA and identified 10 differentiated metabolites related to spleen-kidney Yang deficiency diarrhea. Compared with the model group, all of metabolites recovered to varying levels after being intervened with "Ershen pill", with the best effect shown in the "Ershen pill" IV group (salt-processed Psoraleae Fructus + bran-roasted Myristicae Semen). It is speculated that that Psoraleae Fructus and Semen Myristicae in "Ershen pill" show a synergistic effect by inhibiting peroxide, improving aglucolipid, amino acids and energy metabolism, with multiple target sites.

OBJECTIVETo study the damage effect of benzene on DNA and its mechanism and the changes of antioxidative enzymes in vivo.
METHODSDNA break in bone marrow cells and peripheral blood lymphocytes of mice exposed to benzene by 4 h static inhalation per day at different concentrations for two months were analyzed with single cell gel electrophoresis (SCGE). Meanwhile, the activity of SOD, GSH-Px and the level of MDA in liver, spleen and brain were detected.
RESULTSIn low and high dosage groups, the rate of DNA migration of bone marrow cells (83.56% +/- 10.28%, 92.54% +/- 15.93%) and peripheral blood lymphocytes (41.27% +/- 6.03%, 65.79% +/- 11.62%) were higher than those in control (4.13% +/- 0.52% and 2.21% +/- 0.31% respectively, P<0.05]. The activity of SOD in liver [(754.33 +/- 116.30), (694.26 +/- 116.30) U/mg pro] and GSH-Px [(22.52 +/- 3.31), (18.56 +/- 4.97) U/mg pro] were lower than those in control [(999.92 +/- 188.24) and (35.31 +/- 6.63) U/mg pro respectively, P<0.05, P<0.01]. But there was no significant difference between the two dosage groups. The activity of GSH-Px in spleen of both groups [(31.38 +/- 2.71), (25.30 +/- 7.44) U/mg pro] were lower than that of control [(37.11 +/- 3.42) U/mg pro, P<0.05] and there was significant difference between the two dosage groups. The activity of GSH-Px in brain of both groups [(5.70 +/- 0.84), (5.24 +/- 1.19) U/mg pro, P<0.05] were lower than that of control [(7.10 +/- 0.46) U/mg pro, P<0.05], but there was no significant difference between the two dosage groups. The level of MDA in brain of high dosage group [(3.99 +/- 1.15) nmol/mg pro] was higher than that of control [(2.58 +/- 0.53) nmol/mg pro, P<0.05].
CONCLUSIONChronic benzene poisoning may result in DNA break in bone marrow cells and peripheral blood lymphocytes and decrease in the activity of antioxidative enzymes.

Objective: To establish a method for isolation and purification of fetal membrane derived adherent cells (FMDACs) , and investigate their biological characteristics. Method: FMDACs were isolated with trypsin inducing and cultured in vitro. FMDACs were induced to differentiate into osteoblasts and adipocytes. FACS and immunocytochemistry technique were used to examine the cell surface antigen. The genetic stability was verified by karyotype analysis. Results: FMDACs were successfully isolated and expanded in vitro. They had strong proliferative ability. FMDACs were positive for CD44 and CD29, but negative for CD34, CD14 and CD45. FMDACs were differentiated into osteoblasts and adipocytes after inducement. The karyotype was stable in the sixth-passaged FMDACs and the tumorigenicity was not found. Conclusion; FMDACs have the possibility of multipotent stem cells, which have strong capacities of self-renewal and multidirectional differentiation. The genetic background of FMDACs is stable. FMDACs may be used as a kind of novel seed cells for tissue engineering.

OBJECTIVE:
To investigate the biological characteristics of endothelial progenitor cells (EPCs) from the umbilical cord blood (UCB), and to evaluate their oncogenicity after long-term culture in vitro.
METHODS:
The mononuclear cells (MNCs) were isolated from the UCB and cultured in MCDB131 medium supplemented with 20% FBS, VEGF and other growth factors. Morphology of the EPCs was observed, and the growth curve of the EPCs was investigated. Surface antigens of the EPCs were analyzed by the flow-cytometer. The capability of intaking the acetylated low-density lipoprotein (acLDL) of the EPCs was detected using fluoresencent chemical method. The vasoformative capability and genetic stability of EPCs were cultured in matrigel, and examined by karyotype analysis. The oncogenicity of EPCs was verified by the tumorigenesis test in athymic mouse and soft agar.
RESULTS:
EPCs were successfully derived from the UCB, and could be passaged to at least 42(nd) generation and had strong abilities of proliferation, acLDL intake and vasoformation, but there was not oncogenicity. They expressed endothelial cell-surface antigens and maintained normal karyotype.
CONCLUSION
The EPCs with proliferative potential can be isolated from the UCB. They can be passaged in long-term cultures without oncogenicity, and can maintain normal karyotype. The EPCs can be served as a new type of cells in cell and gene therapy.
