Objective To compare the curative effect of internal fixation treatment between reconstruction-type intramedullary nailing and long anatomic proximal femoral locking plate for patients with ipsilateral femoral proximal and shaft fractures. Methods Twenty-six patients with ipsilateral femoral proximal and shaft fractures were selected, among whom 12 patients were treated with reconstruction-type intramedullary nailing internal fixation treatment (group A), and 14 patients were treated with long anatomic proximal femoral locking plate internal fixation treatment (group B). The fracture to operation time, operation time, intraoperative blood loss, fracture healing time and hip joint function according to Majeed function score were compared between 2 groups. Results The fracture to operation time, operation time, intraoperative blood loss, proximal femoral fracture healing time, femoral shaft fracture healing time and Majeed function score in group A were (6.65 ± 4.11) d, (131.08 ± 20.70) min, (470.83 ± 96.43) ml, (17.83 ± 2.70) weeks, (20.08 ± 3.97) weeks and (83.83 ± 8.13) scores, and those in group B were (7.13 ± 4.56) d, (141.86 ± 27.30) min, (553.57 ± 127.80) ml, (18.29 ± 5.12) weeks, (21.55 ± 4.19) weeks and (83.21 ± 9.58) scores, and there were no statistical differences (P>0.05). According to Majeed function score, in group A excellent was in 7 cases, good in 4 cases, and general in 1 case; in group B excellent was in 9 cases, good in 3 cases, and general in 2 cases. Conclusions A fixation device fixes two fracture is preferred. Both treatment methods used in the present study could achieve satisfactory curative effect, and should be chosen according to the fracture type of the patients and the surgeon′s familiarity for the methods of internal fixation chosen. The proximal femoral fracture should preferably be reduced and stabilized first. A delay of 5 - 6 d would not affect the ultimate curative effect.

Objective To observe the effect of leukocytapheresis(LCAP)on the coagulation,fibrinolysis system and lung injury in the endotoxemia dog and explore the mechanism in the endotoxin-induced lung injury dog. Methods Endotoxemia-induced model in dogs was established by administration of lipopolysaccharide(LPS,2 mg/kg).Separation of the leucocytes wag performed with the automated continuous flow blood cell separators.A total of 30 male mongrel dogs were randomly divided into LPS group(group L,only injected with LPS,with no LCAP),sham LCAP group(group S,received sham LCAP at 12-14 hours after administration of LPS)and LCAP treatment group(group T,received LCAP at 12-14 hours after administration of LPS),10 dogs per group.The dynamic changes of the activated protein C(APC),soluble thrombomodulin and plagminogen activator inhibitor-1 in the serum were measured at 0 hour before LPS administration,at 2,6,12,14,16,24 and 36 hours after administration of LPS.Results Through LCAP,there found the following four results:(1) the APC level in the serum of the group T wag(50.805±4.422)μg/ml and(40.480±2.993)μg/ml at 14 hours and 16 hours respectively,which were significantly higher than(45.881±4.024)μml and(35.935±4.057)μg/ml in the group L(P<0.05).(2)The expressions of soluble thrombomadulin in the group T was (9.688±O.914)μml and(10.492±O.865)μg/ml at 14 hours and 16 hours respectively,which was statistically lower than(11.005±0.854)μg/ml and(12.04±0.954)ug/ml in the group L(P<0.05).(3)Thelevel of plagminogen activatorinhibitor-1 in the group T was lower than that in the group the group T Wag statistically lower than that in the group L(ALI/ARDS occurred in 2 and 7 dogs of the groups T and L respectively within 36 hours after infusion of LPS.P<0.05). Conclusions At the decrease the incidence of acute lung injury partly due to its role in improving the function of coagulation and fibrinolysis.

Eight patients with femoral osteomyelitis were admitted in Lanzhou General Hospital of PLA between July 2012 and July 2015. During the operation the femur was fixed with non-contact locking plate after thorough debridement. Iliac morselized cancellous bones without cortical bone were filled in the bone defect after debridement. The locking plates were placed in the lateral subcutaneous interface superficial to the vastus lateralis muscle. Drainage tubes were routinely placed postoperatively. The surgery was completed successfully in all patients, and the average operation time was (130±10) min (120-150 min). Intravenous antibiotics were administrated for 2 weeks and followed by 4 week-oral antibiotics after the operation in all 8 cases. Drainage tubes remained in situ about 8 days. All patients were followed up for 12-48 months, with an average of (19±7) months. Postoperative X-ray examination showed bone union in 7 cases with an average healing time of (16±5) weeks. One patient failed with relapsed infection, and was later treated with Ilizarov apparatus after secondary debridement. No plate and screw fracture, loose and fixation failure were observed in all 8 cases.
