Periodontal ligament may have independent response to orthodontic stimulation and thus initiate alveolar bone osteogenesis and osteoclasts. Orthodontic-induced alveolar bone remodeling has no bone loss,while inflammation can lead to alveolar bone loss,suggesting that force signal and inflammatory factors may induce the differentiation of undifferentiated cells in the periodontal ligament via different pathways. The strength of the force and the nature of the force (basal tension and fluid shear force) may affect the differentiation of periodontal ligament cells,and may produce antagonistic or synergistic effect with the inflammatory factors through complex autocrine and paracrine regulation,resulting in local bone reconstruction,which is manifested as bone deposition and bone absorption. Studies have shown that Wnt signaling is an important regulatory pathway for osteoblast differentiation. Inflammatory factors can block the differentiation of stem cells into osteoblasts. The Wnt pathway is closely related to the effects of force and inflammatory factors on the differentiation of periodontal ligament cells.

Objective To optimize ethanol extraction technologyDingtongning Granule.Methods With yield of extract and content of tanshinoneⅡA as comprehensive evaluation indexes, the concentration of ethanol, the amount of ethanol, soaking time, extraction time and extraction times were selected as observing factors. Orthogonal design test L18(37) was used to optimize ethanol extraction technology ofDingtongning Granule.Results Optimum extraction conditions were as follows: soaking medicine for 0 hour; 2 times with 6 times of the amount of 80% ethanolre; flux extracted 3 hours each time.Conclusion This optimal extraction technology is stable and reliable, which can provide basis for industrial production ofDingtongning Granule.

In two models for DNA replication and transcription, tra ditional one known as sliding model postulates that proteins involving replicati on and transcription track on the DNA template as a locomotive. In factory model proposed recently, those proteins are immobilized on nuclear structure, to pull the template. Growing evidence from biochemistry, biophysics, and cell biology suggests that the factory model is an actual fact in vivo.

Objective:Our aim was to evaluate the relationship of E-cadherin（EC） expression with the biological behavior of lung cancer.Methods:The EC expression and the cellular DNA ploidy were measured using flow cytometry and immunofluorescence methods in 39 cases of primary non-small cell lung cancer. Systemic pathological examination were performed for all cases.Results:The EC expression significantly reduced in all cases of lung cancer.Fluorescene index(FI) of EC expression was (0.90±0.10) in normal lung tissue， (0.49±0.09) in squamous cell lung cancer,(0.63±0.08) in adenocarcinoma.The expression of EC in squamous lung cancer greatly decreased in poor differentiation and with lymph node metastasis (P<0.01).In squamous cell lung cancer,the expression of EC was lower in uneuploid cancer than that in diploid cancer (P<0.05).The expression of E-Cadherin in squamous cell lung cancer reduced more in TNM Ⅲ than in TNM Ⅰ,Ⅱ.Conclusion:The expression of EC decreased in poor differentiation squamous cell lung cancer with lymph node metastasis. In lung adenoma, the decrease in the expression of EC has no relatoin with the TNM stage, lymph node metastasis, and DNA ploidy.
