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 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.

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 The experimental condition of PEG precipitation pre-treatment method associated with electrochemiluminescence was optimized to gain a coincident result compared with gel chromatography method.Methods A fixed centrifuge time,optimized centrifuge speed,temperature and iron intensity were used to achieve a best experimental condition.Results The detection concentration of micromolecular PRL was approximate to gel chromatography method under the experimental condition of being centrifuged 10 minutes at 18℃ and pretreated with 25%PEG 6000 1M PBS.Conclusions The optimized PEG precipitation test united with the electrochemillumescence immunoassy was a good method for screening macroprolactinemia in clinical diagnosis.
