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.

Long-term outcomes of surgical bile duct injury (BDI) repair are affected by multiple factors, such as surgeon's experience, severity of BDI, pathological changes of the proximal duct, and the manner and timing of surgical repair. However, the timing of BDI repair is still controversial still. In this article, the authors reviewed the correlation of pathophysiologic changes of the proximal duct, repair timing and outcome discussed in English references. It was shown that pathophysiologic changes of the proximal duct are a major contributor to the timing of BDI repair.

Objective To observe the effect of Shenmai injection on congestive heart failure(CHF) and the effect on thyroid hormone as well as medicine security. Methods 52 patieits with CHF were enrolled,Shenmai injection was used with regular western medicine in the treatment. And observed its effect and test serum thyroid hormone: TSH,T3 ,T4 ,rT3. Another 50 CHF patients were enrolled as a control. Results The results of observation were that 25 cases were very effective,23 were effective,4 had no effect and the total effective rate was 92%. The results of control group were that 21 were very effective, 16 were effective, 13 had no effect and the total effective rate was 74%. The differences between the two groups were significant (P > 0.05). By comparing two thyroid hormone T3, T4, rT3, the observation T3 and T4 was obviously higher than the control. rT3 was lower than the control. Conclusion Shenmai injection could efficiently improve the heart function of CHF,cure arrhythmin and correct the illness caused by thyroid hormone.
