Objective: To explore the effects of various concentrations IFN-? on human oral epidermic cancer cell line KB and its multidrug resistant counterpart KBv200.Methods: The toxicity of IFN-? and/or VCR was assayed by MTT method; intracellular rhodamin123 concentration and p-glycoprotein expression were measured by flow cytometry; mdr-1 mRNA was assayed by RT-PCR. Results: High-dose IFN-?(10 000 IU/ml) had significant antiproliferative effects on KB/KBv200 cell lines. Low-dose IFN-? did not have any significant effect on growth of KB/KBv200 cells, but did increase the cytotoxic effect of VCR and the accumulation of Rhodamine123 in KBv200 cell line and had no effect on parent VCR-sensitive KB cell line. IFN-? down-regulated expression of P-gp and mdr-1mRNA . Conclusions: IFN-? has significant effect on the reversal of multidrug resistance of KBv200 cell line via a mechanism of P-gp and mdr1 mRNA down-regulation.

Two regression models, based on panel data over the period of 2000-2011, are built and used to analyze what factors determine China's exports of primary and semi-finished products of traditional Chinese medicine to ASEAN. The results indicate that, China GDP, the ratio of ASEAN to China GDP per capita, average export price, the ratio of state-owned assets to total assets, have a significant positive influence on the export volumes of primary products of Chinese medicine. At the same time, RMB appreciation, the ratio of three kinds of foreign-invested assets to total assets, China-ASEAN Early Harvest Program, ASEAN-China Free Trade Area have a significant negative influence. In respect of the export volumes of semi-finished products of Chinese medicine, the significant influential factors are ASEAN GDP and the ratio of ASEAN to China GDP per capita. The former is positive and the latter is negative. In order to optimize the commodity composition of experts, it is needed to increase export volumes of both primary and semi-finished products of Chinese medicine. According to the analysis above, some proposals are put forward, such as, improving the performance of foreign capital, playing an exemplary and leading role in technological innovation by state-owned enterprises, taking advantage of bargaining power of suppliers, increasing outward foreign direct investment.

OBJECTIVETo investigate the clinical results of external fixation and AO titanium elastic intramedullary nailing for treatment of tibia-fibula comminuted closed fractures.
METHODSFrom June 2010 to June 2012,58 patients with tibia-fibula comminuted closed fractures were treated with external fixation and AO titanium elastic intramedullary nailing, including 31 males and 27 females with an average age of 38.5 years old ranging from 21 to 57 years old. According to the system of AO Classification, the fractures were classified as type B1 in 9 cases,type B2 in 7 cases, type B3 in 10 cases, type Cl in 14 cases, type C2 in 12 cases,and type C3 in 6 cases. According to the system of Winquist-Hanson,the fractures' comminuted were classified as grade 1 in 23 cases, grade 2 in 17 cases, grade 3 in 12 cases, and grade 4 in 6 cases. According to the system of Johner-Wruhs, clinical results were compared between different type and grade groups by the time of last followed-up.
RESULTSAll 58 patients were followed up with an average time of 6.8 months (ranged from 18 to 36 weeks). All fractures had clinical healing with an average time of 28 weeks (ranged from 24 to 32 weeks). The total rate of good to excellent results was 91.4%. The rate of good to excellent in the group of grade 1 was higher than that of other grades. The complication rates and fracture healing time would increase respectively with higher Winquist-Hanson's grade. The complication rates in the group of type C3 was higher than that of other types, but the rate of good to excellent was lower than that of other types. The complication rates in the group of type B1 was lower than that of other types,but the rate of good to excellent was higher than that of other types.
CONCLUSIONMinimal invasiveusing AO titanium elastic intramedullary nailing combined with external fixation for treatment of tibia-fibula fractures especially for the multiple-segment,long spiral mild-to-moderate comminuted with hidden fracture can get satisfactory reduction and reliable fixation,it conformes to the principle of BO completely, protects the fracture end blood supply,reduces the external fixation time, has less skin soft tissue complications, postoperative function recovered satisfactorily.

Objective To discuss the technique and value of preoperative reformatting with three-dimensional computed tomography technique for C_2 pedicle screw track.Methods GE Light Speed 16 Pro spinal CT scans of 15 adult dry vertebrae were loaded into an imaging station (software ADW4.2).Two methods of C_2 pedicle screw techniques were analyzed through virtual screw trajectory by VR (volume rendering) and MPR (multiple planar reformatting) techniques,in method A,screw entry point was the intersection between the media-vertical and the cranial line of C_2 inferior facet joint,in method B,the screw track was from the cranial and medial quadrant of the dorsal part of C_2 inferior facet joint.Results The screw track could be observed dynamically from any plane.Two vertebrae were ob- served with smaller height in isthmus and the medial edge of the transverse foramen since no space was a- vailable for the screw.The screw trajectories data were compared between method A and method B,which showed that the angles towards the cephalad (in sagittal plane) and midline (in transverse plane) were bigger in method A than in method B (P<0.05,0.01),but the safe screw diameter was smaller in method A than in method B (P<0.05),and there was no difference of the screw length between the two methods(P<0.05 ).Conclusion In this research,the individual C_2 pedicle screw entry points, screw diameter and security screw angle can be simulated,and the screw track can be observed dynami- cally to make sure if it transits the bone structure completely.Preoperative three-dimensional computed tomography reformatting for pedicle screw track is of great value in clinical and basic researches.

Objective To investigate the diagnostic value of cervical metastatic lymph nodes by T1 perfusion-weighted imaging and analyse the effect of age on perfusion.Methods 18 cases of cervical lymph node metastasis (case group)and 30 healthy people (control group)were performed T1 perfusion-weighted imaging.The semi-quantitative parameters (including in maximum relative enhancement ratio,wash in rate,wash out rate and peak time)and time-intensity curve (TIC)were compared between case group and control group.Moreover,the effect of age on perfusion was investigated by the age of 40 years old.Results The inflow rate was statistically significant difference between the two groups (P<0.05)and that of 23 cases of metastatic lymph nodes was higher than 49 normal lymph nodes.However,the maximum relative enhancement ratio,outflow rate and peak time weren’t statistically signif-icant difference(P>0.05).The time-intensity curve in metastatic lymph nodes and normal lymph nodes were common in typeⅡ. The maximum relative enhancement ratio and wash in rate negatively correlated with the age and the maximum relative enhancement ratio and wash in rate below the age of 40 years old were higher than above the age 40.Conclusion The wash in rate is helpful to dif-ferentiate metastatic lymph nodes and normal lymph nodes.The effect of age on perfusion is considered.
