Background As the only active component in final treatment phase of Tip-Edge Plus technique,the activation of nickel-titanium orthodontic archwires is one of the factors that affect the torque expression.It is necessary to evaluate the mechanical properties of the nickel-titanium wire used in the final treatment phase in simulated oral environments to forecast the treatment outcomes.Methods The mechanical properties of 171 thermal nickel-titanium wires of 0.35 mm (0.014-in) in diameters with different deflection of 40 mm in length were investigated with three-point bending test.The samples were divided into 2 groups:as-received and bended groups.In the bended group,samples were divided into 7 subgroups according to the amounts of deflection and named by the canine angulations (-25°,-19°,-13°,-7°,-1°,+5°,+11°).The deflection of wires was made by inserting the wires into the deep tunnel of Tip-Edge Plus brackets positioned in plaster casts with different canine angulations to mimic the use of nickel-titanium wires in the final treatment phase.Immersed the bended group in artificial saliva (pH 6.8) and preserved at 37.0°C.Eight durations of incubation were tested:1 to 8 weeks.Three analogous samples of each group and subgroups were tested per week.Stiffness (YS:E) and the load-deflection characteristics of unloading plateau section were obtained.Results Significant changes in specific mechanical properties were observed in long-term immersed and large deflected wires compared with as-received groups.Both immersion time and deflection affected the mechanical properties of wires in the simulated oral environment,and the two factors had synergistic effect.In groups-25°,-19° and -13°,stiffness (YS:E) increased then decreased and average plateau force and ratio of variance decreased then increased correspondingly at specific time.Conclusions In the final treatment phase of Tip-Edge Plus technique,the mechanical properties of nickel-titanium wire are associated with the using time and amounts of deflection and it may affect treatment outcomes.As the main reason for wire deflection,canine crown angulation plays an important role in the wire performance.It may be wise to focus on the canine crown angulations and using time in clinic with Tip-Edge Plus technique and make proper adjustment to help to make sure the treatment outcomes.

OBJECTIVEIn order to explore the roles of Huoxueruanjian compound on liver fibrogenesis and its molecular mechanism, this paper has investigated the Influence of blood serum with such traditional Chinese medicine compound on the expression of Smad3, Smad7 and procollagen alpha2(I) gene in hepatic stellate cell (HSC).

METHODSHSC-T6 was deal with different Concentration of blood serum medicine with Heluoshugan which was made by routine way. Then expression change of Smad3, Smad7 and procollagen alpha2(I) mRNA among each groups were observed by RT-PCR. Furthermore, the expression change of Smad3 protein were examined by Western blot.

RESULTSExpression of Smad3 and procollagen alpha2(I) mRNA as well as Smad3 protein had been downregulated after treating with blood serum medicine of Heluoshugan (P<0.01, P<0.05, respectively). The expression of procollagen alpha2(I) mRNA changed at the same tendency as those of Smad3. The role of blood serum medicine was significant difference between different concentration, P<0.05. And the expression of procollagen alpha2(I) mRNA changed in concentration-dependent manner. Blood serum medicine has no effects on the Smad7 mRNA.

CONCLUSIONThe anti-fibrosis roles of HuoXueruanjian Compound maybe influence the function of TGF-beta and Smad by nonspecific action, thereby inhibit the transcription of procollegan alpha2(I) mRNA and decrease the production of ECM. As regards Smad3, it may be facilitating the development of liver fibrosis when its expression increases. Otherwise, it manifest with anti-fibrosis role.

OBJECTIVETo observe the incidence, causes and deviation angle of axial offset in patients with fracture ununited treated by Ilizarov bone transport technology.

METHODSFrom January 2007 to December 2012, 10 patients with fracture ununited were treated by Ilizarov bone transport including 8 males and 2 females with an average age of (30.3 ± 10.6) years old ranging from 18 to 49 years old. The segment of bone defect involved upper tibial in 2 cases, medial tibia in 2 cases, lower tibial in 5 cases, upper femoral in 1 case. For Paley type of bone defect, 6 cases were type B1, 4 cases were B3. The incidence and deviation angle of axial offset after Ilizarov bone transport technology were observed and evaluated on bone result by Paley assessment.

RESULTSAll patients were followed up from 19 to 32 months with an average of (22.0 ± 5.6) months. Three cases were natural healed at fracture ends, the other 7 cases were healed after bone graft. The time of external fixator was 16 to 28 months. At the last follow-up, there were 3 cases occurred coronal angulation of angle 5° to 11° with an average of (8.7 ± 3.2). Sagittal angulation was in 4 cases, angle 6° to 9° with an average of (8.5 ± 2.1)°. There were 4 cases occurred axial offset. In the last follow-up, according to Paley evaluation criteria, osseous results were excellent in 7 cases, good in 3 cases; functional results were excellent in 6 cases, good in 4 cases.

CONCLUSIONAxial deviation after the Ilizarov bone transport treatment is relatively common, which will result in delayed healing of bone and poor limb alignment. In order to improve the bone healing, corresponding measurements should be taken to avoid or reduce the incidence of axial deviation during and after the operation.
