OBJECTIVETo discuss the clinical effects of external fixator combined with limited internal fixation in the treatment of pediatric distal femur fractures.

METHODSFrom January 2008 to June 2014, 17 children of distal femur fractures were treated by external fixator combined with limited internal fixation. There were 12 males and 5 females, aged from 6 to 13 years old with an average of 10.2 years, ranged in the course of disease from 1 h to 2 d. Preoperative diagnoses were confirmed by X-ray films in all children. There were 11 patients with supracondylar fracture , and 6 patients with intercondylar comminuted fracture. According to AO/ASIF classification, 9 fractures were type A1, 5 cases were type A2,and 3 cases were type C1. The intraoperative and postoperative complications, postoperative radiological examination, lower limbs length and motion of knee joints were observed. Knee joint function was assessed by KSS score.

RESULTSAll the patients were followed up from 6 to 38 months with an average of 24.4 months. No nerve or blood vessel injury was found. One case complicated with the external fixation loosening, 2 cases with the infection of pin hole and 3 cases with the leg length discrepancy. Knee joint mobility and length measurement (compared with the contralateral), the average limited inflexion was 10 degrees (0 degrees to 20 degrees), the average limited straight was 4 degrees (0 degrees to 10), the average varus or valgus angle was 3 degrees (0 degrees to 5 degrees). KSS of the injured side was (96.4 +/- 5.0) points at final follow-up, 16 cases got excellent results and 1 good. All fractures obtained healing and no epiphyseal closed early was found.

CONCLUSIONExternal fixator combined with limited internal fixation has advantages of simple operation, reliable fixation, early functional exercise in treating pediatric distal femurs fractures.

ObjectiveTo investigate the role of T helper (Th) 22 and Th17 cells in the pathogenesis of severe preeclampsia.MethodsThirty women with severe preeclampsia who delivered in the Third Affiliated Hospital of Zhengzhou University from October 2014 to February 2016 were enrolled in the study. Thirty healthy pregnant women matched for age and gestational weeks were recruited as the control group. The frequencies of Th22 and Th17 cells in peripheral whole blood were determined by flow cytometry. The concentrations of interleukin (IL)-22 and IL-17A in plasma were detected by enzyme-linked immunosorbent assay. Independent two samplest-test, non-parametric test and Spearman correlation analysis were used for statistical analysis.ResultsThe percentage of Th22 and Th17 cells in the severe preeclampsia group were significantly higher than those in the control group, respectively[Th22 cells: 0.59% (0.39%-1.13%) vs 0.40%(0.23%-0.57%),Z=2.530,P=0.010; Th17 cells: 3.24% (3.02%-3.97%) vs 1.87% (1.53%-2.64%),Z=5.046, P=0.000]. So were the plasma levels of IL-22 and IL-17A[IL-22: 285.72 (247.63-306.69) vs 233.85 (184.92-258.38) pg/ml,Z=4.341,P=0.001; IL-17A: 27.53 (23.84-32.78) vs 17.36 (15.58-19.13) pg/ml,Z=4.924, P=0.000]. There was a positive correlation between circulating Th22 and Th17 cells in the severe preeclampsia group (r=0.534,P=0.015), while no correlation was found in the control group (r=0.345,P=0.136). Positive correlation was found in plasma level of IL-22 with Th22 cells (r=0.600,P=0.005), but not with Th17 cells (r=0.398,P=0.082) in the severe preeclampsia group.ConclusionsIncreased Th22 cells and high IL-22 concentrations in the peripheral blood of severe preeclampsia patients may indicate a self-defense mechanism in the maternal body. Th22 cells and Th17 cells may interact with each other.

OBJECTIVETo investigate whole blood viscosity changes at different time points in rats model with lumbar vertebrae semidislocation, study Shi's theroy of qi and blood and "Gucuofeng and Jinchucao" [symbols: see text], also reveal pathological physiology characteristics of spinal disorder.

METHODSThirty-six SPF male rats weighted 350 to 450 g were randomly divided into rotatory fixation group (RF group), simple fixation group (SF group) and Sham group (Sham group), 12 rats in each group. Exterior vertebrae implanted through L4-L6 segments of lumbar vertebrae in RF and SF group were connected fixed device. In RF group, L5 spinous process were rotated to right, and caused L5 spinous process was non collinear with L4 and L6; in SF group, external fixed device were simple connected without rotation. At 1, 4, 8 and 12 weeks after fixation, whole blood viscosity changes were tested.

RESULTSAt 4 and 8 weeks after fixation, high (150/s), medium (60/s) and lower (10/s) shear rate in RF and SF group were higher than that of Sham group (P<0.05). At 1 and 12 weeks, there was no sigificant differences among three groups in whole blood viscosity (P>0.05).

CONCLUSION"Gucuofeng and Jinchucao" [symbols: see text] vertebrae could raise whole blood viscosity, increase degree of bloos stasis and induce or aggravate spinal disorder in further.
