Target restoration space (TRS) is the most precise space required for designing optimal prosthesis. TRS consists of an internal or external tooth space to confirm the esthetics and function of the final restoration. Therefore, assisted with quantitive analysis transfer, TRS quantitative analysis is a significant improvement for minimum tooth preparation. This article presents TRS quantity-related measurement, analysis, transfer, and internal relevance of three TR. classifications. Results reveal the close bond between precision and minimally invasive treatment. This study can be used to improve the comprehension and execution of precise esthetic prosthodontics.

Calcium-sensing receptor(CaSR) is a widely distributed G-protein coupled receptor.The activated CaSR plays an important role in many kinds of signaling pathway regulation, such as Ca2+ signaling pathway.It not only maintains the body calcium balance, but also is involved in the regulation of a variety of cell secretion, proliferation, apoptosis, and ion channel opening processes.CaSR expression is involved in stem cell migration, adhesion and homing in hematopoietic stem cells and mesenchymal stem cells.The activated CaSR also regulated the function of itself and characteristics in stem cells through a variety of cell signaling pathways.We introduce the functions and characteristics of CaSR, the relationship between CaSR and disease, and review the effects of the biological characteristics on hematopoietic stem cells and mesenchymal stem cells.

AIM: To establish cell line FL-POL? - and to study the role of POL?(polymerase kappa) on genetic stability. METHODS: A mammalian expression vector expressing antisense POL? gene fragment pMAMneo -amp -- POL? was constructed by cloning the 1 690-1 918 fragment of POL? gene into the mammalian expression vector pMAMneo-amp - in antisense orientation. FL cells were fransfected with this antisense RNA expressing vector and selected by G418. Based on the shuttle-plasmid pZ189, the mutation assay was made. RESULTS: The spontaneous mutation frequency of supF tRNA gene in the plasmid replicated in the FL-POL? - was 11.2?10 -4 , while it was 4.9?10 -4 and 3.7?10 -4 in the control cells FL and FL-M , respectively. CONCLUSION: POL? playes an important role in maintenance of genetic stability.

Objective To identity bacteria of bacteroides group by PCR.Method The universal primers were designed according to the sequence of 16S rRNA,then 13 strains bacteroides and the other non-bacteroides were amplified by PCR. PCR products were then sequenced and analyzed by Blast.Results Thirteen strains of bacteroides were amplified, and the non-bacteroides were not amplified. The pairs of primers had highly specificity.Comparing the gene sequences of the 13 strains,bacteroides with corresponding standard 16S rRNA sequences,the homology was from 81% to 100%.Conclusion The established PCR assay could specially amplify bacteroides and had good sensitivity with 100 genomes/ml.

Objective To realize information sharing and medical resources integration in different medical enterprises.Methods In accordance with IHE XDS-I image data registration-distribution model,regional data exchange center was set up so that the medical images and report data could be exchanged and shared,and the regional medical network could be smoothly upgraded in interconnection.Results Exchange and sharing of medical images and reports were realized.Standard IHE data interface was prepared for future images exchange between different hospitals.XDS-I model in domestic hospitals were put into practice.Conclusion The structure design of data center is feasible,reliable and effective.

Objective To study the result of DSA for 56 cases with large liver cancer that there is bloody supply from arteria musculophrenica right and the clinical value of super selective interventional embolization,so that to improve the clinical curative effects of interventional therapy. Methods Employ 4F, 3F catheter super selectively into arteria musculophrenica that supply blood to cancer. Result 56 cases(21.7% )were discoverod that there was bloody supply from arteria musculphrenica right to cancer in 258 cases with large liver cancer, liver neoplastic size of all cases wasin 5～15cm,22 cases(8.6% ) were discovered in the first interventional operation,34 cases ( 13.3% )were discovered in the second or the third interventional operation. Obvious tumor shrinking in all cases: the 6month survival as 56 cases(100 % ), the 1-year survival as 45 cases (80.4%), the 2-year survival as 21 cases(37.5%). Conchssion Arteria musculophrenica right supply blood to cancer is common in large liver cancer eases, super selectively embolized the supply blood from the arteria musculophrenica right is very important for acquiring success by interventional operation.

Objective: To investigate the effect of sinomenine on expression of toll like receptor(TLR) 2 and TLR4 of dendritic cells in patients with rheumatoid arthritis in vitro.Methods: The peripheral blood mononuclear cells were isolated from 10 rheumatoid arthritis patients and differentiated into dendritic cells by stimulating with cytokines.Dendritic cells were exposed to high(5mM),middle(2mM),low(1mM) concentration sinomenine and control medium.TLR2 and TLR4 mRNA were detected by real time PCR.Western blot was used to measure the expression of TLR2 and TLR4.Results: In contrast to control,signifi cant lower expression of TLR2,TLR4 mRNA and protein were found in dendritic cells treated with sinomenine,especially in high and middle concentration.Conclusion: The therapeutical effect of sinomenine on rheumatoid arthritis is probably by inhibiting dendritic cells expressing TLR,which can transduce the in? ammatory signal.

[Objective]To statistically analyze the citations of papers in "The Orthopedic Journal of China"published during 2004~2006.[Method]Using the biblio metric method to calculate the citation rate,number of citations per paper,types of citations,language-based citation number,Price index and self-citation rate.[Result]During 2004~2006,the average citation rate was 94.32% and the number of citations per paper was 6.31.The number of citations in English was significantly higher than that in Chinese or other foreign languages.Meanwhile,the citation rate of papers published in journals was markedly higher than that of those published in books and other materials.The Price index and self-citation rate were 71.48% and 8.74%,respectively.[Conclusion]"The Orthopedic Journal of China"is shown to be a hight professional academic journal in China,with good novelty citation,high level of authors' education and extensive social influence.
