Objective To observe the effect of acupuncture on post-stroke belching. Method Ninety-six patients with post-stroke belching were randomized into a control group and a treatment group by random number table, 48 cases in each group. The control group was intervened by conventional Western medication, while the treatment group was by acupuncture in addition to the medication given to the control group. The blood Cl﹣ and Ca2﹢ contents, as well as the symptoms score and occurrence of adverse reactions were compared before and after treatment. Result After intervention, the blood Cl﹣ and Ca2﹢ contents increased and the symptoms score decreased to different extent in both groups; except for the blood Ca2﹢ content, there were significant differences in comparing all the parameters between the two groups after intervention (P<0.05); there was a significant difference in comparing the occurrence of adverse reactions between the two groups (P<0.05), and there were less adverse reactions in the treatment group. Conclusion Acupuncture can effectively control the post-stroke belching and reduce the happening of adverse reactions.

Objective:To investigate the temporal and spatial distrib ut ions of collagenⅠ and Ⅲ during mouse tooth germ development and their function s during tooth mineralization.Methods:Immunohistochemistry stain ing technique was used to test the expressions of collagen Ⅰ and Ⅲ during mous e tooth germ development. Results:collagen Ⅲ was positive in or al epithelial cells in bud stage,in oral epithelial cells and in stellate reticu lum cells in cap stage. During bell and differentiation stage,collagen Ⅲ was positive in oral epithelial cells, stellate reticulum cells, dental papilla cell s and dental sac cells. During P2-10 d(crown development stage), collagen Ⅲ was expressed possitively in ameloblasts,enamel matrix,odontoblasts,predentin, dental papilla cells,dental sac cells and pulp tissues. During P10-30 d(toot h root development stage),collagen Ⅲ was strongly positive in Hertwig's epithe lial root sheath, cementum, alveolar bone and periodontal ligament cells apart f rom above mentioned cell types. CollagenⅠ was not expressed in bud stage and wa s positive in oral epithelial cells,stellate reticulum cells in cap stage. Durin g bell and differentiation stage,collagen Ⅰ was positive in oral epithelial ce lls, stellate reticulum cells, dental papilla cells and dental sac cells.After P2 d (crown and root development stage), the distribution and expression of co llagen Ⅰ were similar to those of collagen Ⅲ.Conclusions:Coll agenⅠand Ⅲ are involved in tooth germ and tooth tissue development. But the fu nction of collagenⅢ is more extensive than that of collagenⅠ.

Objective:To prepare and identify a polyclonal antibody againstadam28 gene product.Methods:Theprotein coding region of ADAM28 was amplified by RT-PCR and cloned into pMD18-T Vector to produce the newconstruct, pMD18-T-adam28. The cloned ADAM28 segment was cut with two restriction enzymes and theadam28fregment was directed into the prokaryotic expression vector, pGEX-4T-1,to produce the expression vector pGEX-4T-adam28. The recombinant plasmid was transformed intoE. coliDH5?and GST-ADAM28 fusion protein was ob-tained after the inducement by IPTG. The fusion protein was extracted and purified by SDS-PAGE,and the newpro-tein band of 35 300 was isolated as antigen, the antigen was injected into rabbits to produce polyclonal antibody a-gainst ADAM28 product.Results:The expression vector pGEX-4T-adam28 was constructed successfully,and GST-ADAM28 fusion protein was obtained. The rabbit serum containing polyclonal antibody against ADAM28 productwas obtained and the antibody was purified by salting out method. Western blot analysis displayed that the antibodyhad high specificity. ELISA analysis confirmed that the titer for the antibody reached 1∶16 000.Conclusion:Thepolyclonal antibody against ADAM28 product with high titer is successfully prepared,it may be used for further studyof the role and expression of ADAM28 during tooth development.

Recombinant antibodies have become the major growth trends in biotech industry following their success on therapeutic application and good revenue. But the low level of mammalian expression and laggard fermentation process constrained the development of antibody industry in China. The global advances of antibody industry were reviewed, compared the respective advantage between dihydrofolate reductase and glutamine synthetase expression system, continuous perfusion and fed-batch processes were compared. Finally, based on the knowledge and experience of antibody expression and fermentation, the suitable strategy of antibody industrialization, e.g. the fermentation model and scale, should depend on the comprehensive consideration of entrepreneur for the productivity, manufacturing capacity and market revenue. It may be a wise choice to use glutamine synthetase expression system and continuous perfusion process for the need of Chinese antibody industrialization.

Objective:To investigate spatiotemporal expression of ADAM28 in mouse tooth germ development.Methods:Immunohistochemistry and image analysis technique were used to observe the expressions of ADAM28 at mouse tooth germ development stages.Results:Different expression levels of ADAM28 at tooth germ development stages were observed.At cap stage,ADAM28 was found strongly positive in oral epithelial,stellate reticulum cells of enamel organ,basement membrane,dental papilla cells and dental sac cells.At late bell stage,positive staining was found in ameloblasts,enamel matrix,epithelial root sheath and dental papilla cells.At crown and root development stage,positive staining for ADAM28 was detected in ameloblasts,odontoblasts,cementoblasts,epithelial root sheath,dental papilla cells and dental sac cells.Conclusion:ADAM28 participates in crown and root morphogenesis process ranging from bud stage to late bell stage and from matrix secretion to sclerous tissue formation.It might play an important role in early formation,proliferation and differentiation of odontogenic mesenchymal cells.
