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 observe the effect of comprehensive rehabilitation on breast cancer related lymphedema. Methods 70 patients with breast cancer related lymphedema were divided into experiment group (n=35) and control group (n=35). Both groups received intermittent pneumatic compression, while the experiment group received comprehensive rehabilitation including manual lymphatic drainage, muscle stretching, expanded the range of motion of shoulder, gradual resistance training, high frequency electrical therapy and health education. They were assessed with Disabilities of Arm, Shoulder and Hand Scale (DASH) and development of lymphedema before and 8 weeks after treatment. Results DASH scores and the development of lymphedema improved in both groups after treatment (P<0.05), and improved more in the experiment group than in the control group (P<0.05). Conclusion Comprehensive rehabilitation can further relieve breast cancer related lymphedema, and improve the upper extremity function.

Objective To investigate the effects of proprioceptive training and core stability training on the lower limbs motor function and balance in patients with hemiplegia after stoke. Methods 40 patients were randomly divided into treatment group (n=20) and control group (n=20). Both groups received routine rehabilitation and the treatment group received proprioceptive training and core stability training in addition. They were assessed with Fugl-Meyer Assessment (FMA) of lower limbs, Functional Ambulation Category (FAC), Berg Balance Scale (BBS), Timed Up-and-Go Test (TUGT) before and 6 weeks after treatment. Results The scores of FMA, FAC, BBS and TUGT improved in both groups after treatment (P<0.01), and improved more in the treatment group than in the control group (P<0.05). Conclusion Addition of proprioceptive training and core stability training may further improve the lower limbs motor function and balance of the hemiplegics after stroke.

Objective: To investigate the expression of pituitary tumor transforming gene (PTTG) and basic fibroblast growth factor (bFGF) in oral squamous cell carcinoma and their relation with each other, as well as the relationship of their expression with clinical-pathological indexes. Methods: The expression of PTTG and bFGF were examined among 55 oral squamous cell carcinoma tissues and 10 normal oral mucosal tissues by the streptavidin-biotinperoxidase (S-P) method. Results:The positive rate of PTTG and bFGF was 78.2% and 67.3% respectively in oral squamous cell carcinoma. The positive rate and grade of PTTG and bFGF were significantly higher than that in the normal mucosa tissues (P

The 52-year-old female patient complained of persistent and progressive obstruction in left nasal cavity for more than 1 years. A grey, hard and smooth tumor with telangiectasia, were seen plugged in left post-nostrils and nasopharynx. CT scanning showed a tumor in the left nasal cavity. Post-operational pathologic diagnosis was peripheral nerve sheath tumors of nasal cavity.

Objective To explore the effect of transcranial magnetic stimulation (TMS) on gross motor function for children with cerebralpalsy. Methods 80 children with cerebral palsy treated in our hospital during July 2009 to January 2010 were divided into control group(n=40) and observation group (n=40). The control group received conventional treatment, including physical therapy, massage, scalp acupuncture,body acupuncture, point injection, physiotherapy and medication. The observation group received TMS in addition. The therapeuticeffects were compared using the Gross Motor Function Measure-88 (GMFM-88) after 3 months. Results The percent scores of all the domainssignificantly increased in both groups (P<0.05) after treatment, the increased percent scores of observation group in B domain, D domain,E domain and total were higher in the observation group than in the control group (P<0.05). Conclusion TMS can further improve thegross motor function of children with cerebral palsy.

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.

Objective To explore the influence of some factors on long-term survival of postoperative stage Ⅰ NSCLC patients. Methods 91 patients of NSCLC who underwent radical surgery of the primary tumor with dissection of the hilar and mediastinal lymph nodes were diagnosed as stage Ⅰ NSCLC postoperatively by pathology and followed up for 5 years. Its hilar and subcarinal lymph nodes were detected occult micrometastastic tumor cells by immunohistochemistry (SP method) by using the binoclonal antibody multicytokeratin (AE1/AE3) as a micrometastatic marker. To analyse the influence of micrometastasis and the clinicopathologic characteristics on long-term survivals. Results The rate of micromatastasis of stage Ⅰ NSCLC was 49 %. The five-year overall survival rate was 70.3 %. The median of survival time was 48.5months. The rate of metastasis was 32 % and the meantime of relapse and metastasis was 36.6months. Tumor size, differentiation, stage, and micrometastasis were significantly associated with relapse and metastasis (P <0.05). The tumor differentiation, stage, and micrometastasis were found to be significant independent factor on survival in multivariate analysis (P<0.05). Conclusion There was nodal micrometastasis in completely resected stage Ⅰ NSCLC, and the tumor differentiation, stage, and micrometastasis were found to be significant independent factor on survival.
