Aptazymes are a new artificial synzyme, selected from the random oligonucleotide sequence libraries against various of effector molecules. They own the advantages of an aptamer(the receptor site) and the ribozyme (the catalytic active site). Moreover, aptazymes as catalytic molecular beacon provide a new orientation for the quantitative analysis of effector molecules. Aptazymes not only have the application in genomics and proteomics, but also have potential applications in biosensor and DNA AND gate.

With the economic development, more and more people concerned about health. Institution and people engaged in physical examination is springing up. Facing increasingly less obvious advantages of product homogeneity, and the growing market which must cater to different customers, as a large general hospital medical center, we should make good management of customer relationship, improve customers' satisfaction, increase their loyalty, provide the most effective health protection for the physical examination so as to improve market competitiveness and bring social and economic benefits to the hospitals, thus achieving a win-win objective.

0.05).The smoking group had a higher TG level and a lower HDL-C level than the control one with statistical significance(P0.05).The HL activities in serum,lung and liver of smoking group were lower than those of control group(P

Excellent doctor education training plan is an important policy applied by the gov-ernment to enhance the quality of medical personnel training in China. One of the important purposes is to improve the medical students' ability to apply and practice the medical professional English. In order to achieve this purpose, we have applied bilingual teaching for the students of excellent doctor in medical cell biology course. This article mainly introduces some reform measures , which involves training teacher, preparing textbooks and resources, establishing network database, exploring teaching modes, improving teaching methods and means, implementing diversified evaluation methods, and so on. At the same time, we have summarized some problems in the teaching process, and thus put for-ward improvement strategy.

?DJ-1 has been reported to act as aredox-activated chaperone and sensor of oxidative stress participated in a variety of activities in cellular, playing an important role in resisting oxidative stress, regulating signaling pathways and gene transcription, and maintaining mitochondria dynamic balance. DJ -1 is closely related to the occurrence and development of various diseases. Recently, the effect of DJ-1 in eye diseases has drawn more attention, and researchers have found its significant role of resistance to oxidative stress in the pathogenesis of Fuchs endothelial corneal dystrophy ( FECD) and age-related macular degeneration ( AMD ) .This review will state the mechanism of DJ-1 against oxidative stress and its role in the development of eye diseases.

Objective To further research the biological functions of PES1,the ovarian SKOV3 cell line with inducible stable PES1 expression is established by using Tet-on system.Methods PES1 was cloned into pTRE-Tight vector via PCR and its expression was identified. After transfected the regulating plasmid pTet-on,SKOV3 cells were screened with G418 and re-transfected pTRE-Tight-PES1.The positive cell clones were screened out with hygromycin and were induced by doxycycline (Dox) to definite the best induction concentration.Growth velocity of SKOV3 cells stably expressing PES1 induced by Dox was detected with viola crystallina.Results The SKOV3 cells with inducible PES1 expression were screened out after the cells were transfected pTRE-Tight-PES1 constructed.Dox could dose-dependently induce the PES1 expression with the concentration under 2 mg/L,and 2 mg/L of Dox induced the highest PES1 expression.Growth velocity of SKOV3 cells transfected pTRE-Tight has no significant difference between the SKOV3 cells transfected nothing induced with Dox.However,the SKOV3 cells transfected pTRE-Tight-PES1 grew faster than the cells transfected pTRE-Tight or without transfection in the fourth day (P =0.001 ).Conclusion The inducible stable PES1 expression SKOV3 cells are successfully established and could be used to be an effective cell model to research the biological functions of PES1.The expression of PES1 could promote the growth of SKOV3 cells.

ObjectiveTo establish a analytical system for the survival motor neuron (SMN) subtle mutation,and evaluate its application in two families with spinal muscular atrophy (SMA).MethodsSMN genes in seven family members from two SMA families were analyzed at both transcript level and genomic level,by the use of the conventional PCR-RFLP,allele-specific PCR,multiplex ligation-dependent probe amplification (MLPA) and T subcloning and sequencing of SMNI gene.ResultsIn family A,the patient had a single SMN1 copy who was carrying nonsense mutation L228X,which was also found in his father.In family B,as the patient's sample was unavailable,the father was indeed a carrier with one normal SMN1 allele and the other SMN1 allele carrying a frameshift mutation 22_23insA.The remaining family members were SMA carriers with one SMN1 copy.ConclusionThis analytical system for SMN subtle mutation offers viable molecular basis for genetic counseling and prenatal diagnosis in SMA families.

Aim To develop a rapid and inexpensive method for purification of human albumin, a method of immunomagnetic microspheres (IMMS) based on enzyme-linked immunosorbent assay (ELISA)for the purification of human albumin from human serum. Methods Polystyrene magnetic microspheres with carboxyl groups as carriers were prepared, and then the carboxyl groups on the surface of the microspheres were activated by ethylcarbodiimide (EDC). Finally rabbit anti-human serum albumin (HSA) antibodies were covalently bound to it and the complex can specifically capture HSA. After the procedure of capturing HSA, through taking rabbit anti-human albumin protein antibodies as a capture antibody, and goat anti-human albumin protein antibodies as a detection antibody, an ELISA on IMMS was developed, which can determine the recovery yield of HSA from the human serum. Results The result of the experiment was that the recovery of human albumin with IMMS was (86 ± 4) % , and IMMS were reused for two other purifying cycles, the results of which were (69.0 ± 0.6) % and (40.8 ± 0.8) % , and the purity of the product was about 90%. Conclusion The results above prove that the immunomagnetic purifiying strategy was shown to be efficient and offers an new thought for a large scale production of highpurity HSA.

The popularization of reading ancient books on traditional Chinese medicine has been in abasinstate due to their contents , their readers and the reading competence of their readers .The role of media guidance in popu-larization of reading ancient books on traditional Chinese medicine was thus elaborated with the exhibition of ancient books on traditional Chinese medicine in Library of Nanjing University of Traditional Chinese Medicine as an exam-ple, which may provide certain reference for changing the ideas of libraries and popularizing the reading of charac-teristic documents .
