ABSTRACT
<p><b>OBJECTIVE</b>To study the effects of Osteoking in promoting gene expression of core binding factor alpha 1 (cbfalpha 1) in necrotic femoral head of rabbits.</p><p><b>METHODS</b>Rabbit model of femoral head necrosis (FHN) was induced by intravenous injection of lipopolysaccharide (LPS) 10 microg/kg body weight twice with an interval of 24 h and intramuscular injection with methyl prednisone (MPS) 20 mg/kg body weight 3 times. The dynamic changes of cbfalpha 1 gene expression in the femoral head were observed with immunohistochemistry and real-time quantitative PCR.</p><p><b>RESULTS</b>The protein expression of cbfa 1 gene was negative in both model and treatment groups at the 4th week, it turned to weakly positive in the treatment group at the 8th and 12th week but still negative in the model group. The mRNA expression of cbfalpha 1 in the treatment group was 2.87 times that in the model group at the 12th week. There was no significant difference in cbfalpha 1 expression between the normal rabbits with or without Osteoking treatment.</p><p><b>CONCLUSION</b>Osteoking could promote the endogenous cbfalpha 1 expression in the FHN, the effect is better along with the prolonging of the time applied. But it showed no affection on cbfalpha 1 expression in the normal femoral head of rabbits.</p>

Objective To explore the clinical outcome of self-designed bilateral external fixator combined with limited internal fixation for the treatment of open fracture of tibial plateau.Methods From February 2001 to September 2005,23 cases of open tibial plateau fractures were treated with bilateral external fixator combined with limited internal fixation.According to Schatzker classification,there were 35 patients with type Ⅴ fracture and 18 patients with type Ⅵ fracture.According to Gustilo classification,there were type Ⅰ in 15 eases,type Ⅱ in 22 cases, type Ⅲ in 16 cases.Results The follow-up period was 5 to 22 months(mean 10 months).All the fractures got unit- ed.According to Merchant grade,18 eases were evaluated as excellent,25 as good,9 as fair.The rate of excellent and good resuhs was 83 %.Conclusion Operation by using bilateral fixator combined with limited internal fixator can make fixation stable and reduce complication.It is an effective method to treat complex fractures of open tibial plateau.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the effect of Osteoking ( masculine(1)i) in preventing postoperational deep venous thrombosis (DVT) in patients with intertrochanteric fracture (ITF).</p><p><b>METHODS</b>With prospective and randomized controlled clinical design adopted, 62 patients with ITF after operation were assigned into 2 groups, the tested group and the control group, Osteoking (25 ml every other day) and Sanchi-dansheng tablets (3 tablets thrice a day) were given orally to them respectively for 10 days. Difference of round length of thighs and shanks between two sides were measured on the 10th day and Doppler ultrasonic examination on the fractured leg was carried out.</p><p><b>RESULTS</b>The occurrence rate of DVT in the tested group was 9.4%, which was lower than that in the control group (30.0%, P < 0.05). All the difference of round lengths, either that of the thigh or the shank, was less in the tested group than that in the control group, showing statistical significance (P < 0.05).</p><p><b>CONCLUSION</b>Osteoking has a satisfactory effect in preventing postoperational DVT in patients with ITF.</p>
