RESUMO
OBJECTIVE: To determine the influence of altered masticatory loading on Indian hedgehog (Ihh)-parathyroid hormone-like related protein (PThrP) pathway in the condylar cartilage of growing rabbits. METHODS: A total of 48 10-day-old rabbits were randomly divided into two groups and fed different kinds of food, such as solid diet and soft diet. The animals were sacrificed after 2, 4, 6, and 8 weeks. Difference of Ihh and PThrP expression levels induced by altered masticatory loading was tested by hematoxylin-eosin (HE), immunohistochemistry, Western blot, and real-time polymerase chain reaction (PCR). RESULTS: The thickness of condylar cartilage and expression levels of Ihh and PThrP proteins and mRNA of the solid diet groups exceeded those of the soft diet groups. The decreasing tendencies of the expression levels of Ihh and PThrP proteins and mRNA were observed at 2, 4, 6, 8 weeks. CONCLUSIONS: Low masticatory loading may delay or inhibit the development of condylar cartilage and its growing factors Ihh and PThrP. Therefore, masticatory loading plays an important role in the development of condylar cartilage.

Objective To evaluate the effect of clinical pathway in pulmonary thrombus embolism (PTE) .Methods 60 cases of PTE were admitted department of respiratory from 2011 to 2012 and divided into the experimental group and the control group ,30 cases for each group .The control group was implemented with normal process of hospital management while experimental group de-veloped clinical pathways .The efficacy ,department of respiratory drug costs ,complications and patient satisfaction were recorded and computed .Results The average department of respiratory and drug costs in experimental group respectively was (17 .13 ± 2 .22)days ,(16 545 .04 ± 1 557 .44) RMB and (7 050 .83 ± 372 .74) RMB ;less than (19 .77 ± 3 .41)day ,(17 709 .45 ± 1 902 .05) RMB and (7 345 .75 ± 450 .82) RMB in control group ,there were significant difference between the two groups (P0 .05) .Conclusion The effect of clinical pathway in PTE have a positive role in reducing hospitalization time ,total costs ,drug costs and increasing satisfaction ,it is worth to develop in primary hos-pital .
