With the application of monoclonal antibody technology more and more widely, its production technology is becoming more and more perfect. Small molecule monoclonal antibody technology is becoming a hot research topic for people. The application of traditional Chinese medicine small molecule monoclonal antibody technology has been more and more widely, the technology for effective Chinese medicine component knockout provide strong technical support. The preparation of monoclonal antibodies and small molecule knockout technology are reviewed in this paper. The preparation of several steps, such as: in the process of preparation of antigen, hapten carrier coupling, coupling ratio determination and identification of artificial antigen and establishment of animal immunization and hybridoma cell lines of monoclonal antibody, the large-scale preparation; small molecule monoclonal antibody on Immune in affinity chromatography column method is discussed in detail. The author believes that this technology will make the traditional Chinese medicine research on a higher level, and improve the level of internationalization of Chinese medicine research.

6-11 years old were 9.67%, 6.81%, 3.49% and 0.80%, respectively.Furthermore, the infection rates between each two age stages were significantly different(Pa0.05).4.Infection rates in 2005,2006 and 2007 were 4.0%, 8.92%, 8.85%,respectively.Infection rates between 2005 and 2006,2007 were significantly different(Pa

Selection and affinities of Cd binding peptides were assayed by phage random dodecapeptide library and affinity chromatography. Two Cd binding peptides were obtained, it was found that the affinities of Cu~ 2+ ,Co~ 2+ ,Zn~ 2+ ,Ni~ 2+ for Cd binding peptides were higher than that of Cd~ 2+ and Cr~ 2+ after detection of the amplified Cd binding peptides displayed phages to different heavy metal-charged resins; the detoxification of E.coli to Ni~ 2+ and Cd~ 2+ was enhanced when infected by Cd binding peptide displayed phages as compared with those of the control. The interaction of Cd binding peptide displayed phages with heavy metals charged resins was also observed under microscope. The work would be of great value and consequences for the study of interaction between heavy metals and proteins(peptides), as well as thedetoxification and bioremediation of heavy metals.

OBJECTIVEObserving the effect of phenolic acids from Arnebia euchroma assist mifepristone in anti-early pregnancy of SD rattus norvegicus.

METHODFeed the SD rattus norvegicus with phenolic acids from A. euchroma during the 7 th to 9 th day, and then we observe the restaining rate of pregnancy. At the same time, we determine the progesterone level in blood serum in the ways of radioimmunoassay.

RESULT720 g x kg(-1) enolic aids from A. euchroma can markedly increase the restaining rate of pregnancy (P < 0.05) than that only mifepristone dose (8.0 g x kg(-1)). In addition, the number of everage still bith increase, however, to the pogesterone level in blood serum. It has little effect.

CONCLUSIONThe effect of phenolic acids from A. euchroma assist mifepristone in anti-early pregnancy of SD rattus norvegicus is clear, and it dosen't work in the ways of decreasing the pogesterone level.

Objective To investigate the optimal scheme about the external loading of resetting tensile stress for clavicular fracture,so as to provide some mechanical references for optimal design of external fixators for clavicular fracture.Methods The shoulder CT scanning data from a volunteer were used to establish the three-dimensional model of human left shoulder by Mimics software.In order to better simulate the actual human shoulder,the ligament tissues were added in the model and the constraints of muscles were considered,and the experimental model for simulation analysis on resetting tensile stress was established.By 3 simulation experiments,the impacts from directions of resetting tensile stress,positions of action points and value ranges were simulated and analyzed,respectively.The resetting tensile stresses obtained from clavicle of the shoulder model under various external loading cases were simulated by orthogonal test methods.Results When the θ (angle between the horizontal plane projection of shoulder force which was loaded by external fixator and the coronal axis) was greater than 45°,clavicle could obtain the resetting tensile stress,which became greater with the angle θ increasing.When η (angle between the sagittal plane projection of shoulder force which was loaded by external fixator and the sagittal axis) was 30°-45°,the resetting tensile stress of clavicle was the maximum.The farther the position on which the loads from external fixator was exerted from the horizontal position of clavicle,the larger the resetting tensile stress of clavicle was.Conclusions The results of orthogonal test show that the optimal resetting tensile stress is produced with parameter combination of θ =65°,η =50°,acting on the center of humerus head of the shoulder.

OBJECTIVETo study the pharmacologic characteristics in synergism and complementation of 999 Ganmaoling (GML), a compound recipe composed of Chinese and Western materia medica (CMM & WMM), as well as its theoretical basis of matching of Chinese and Western materia medica.

METHODSThe torsion response induced by glacial acetic acid in mice, toe swelling induced by carrageenanin rats, delayed hypersensitive response in mice and fever induced by endotoxin in rats and rabbits were used to comparatively study the actions of CMM & WMM in GML. The effect of CMM in antagonizing liver damage caused by WD (acetaminophen) in mice was also studied. RT-PCR method was used to analyze the expression of related cytokines.

RESULTSGML showed a significant antipyretic and analgesic effect, it could inhibit the carrageenan induced inflammation, antagonize the endotoxin induced fever, and promote the amount for expression of cytokines in rats' splenic tissue with pneumococci infection to some extent. The CMM in GML showed certain protective effect on acetaminophen induced liver damage.

CONCLUSIONGML has a potent antipyretic, analgesic and anti-inflammatory effects, CMM & WMM in GML showed markedly synergism and complementation, and CMM in it has liver protective effect.

A in vitro platelet aggregation bioassay was developed for the quality control of XST capsules. The in vitro anti-platelet aggregation effect in rats was observed to detect the bioactivity of XST capsules. Panax notoginseng saponins and Xuesaitong lyophilizedpowder for injection were taken as standard control substances to determine the potency. According to the results, XST capsules showeda significant inhibitory effect on thrombin-induced platelet aggregation in a dose-dependent manner. The in vitro anti-platelet activity oflyophilized powder for injection was stabler than that of Panax notoginseng saponins, and so suitable to serve as a standard control substance. The biological potency of XST capsules compared with standard control substance was detected by using parallel line assay. According to the results, the established bioassay method had a good repeatability (RSD 2.92%). The sample test results could pass thereliability test(linear deviation P > 0.05, parallel deviation P > 0.05). This bioassay method could be used as one of the complementary quality control methods for XST capsules.
