BACKGROUND:Surface modification of orthopedic implants can reduce or prevent bacterial adhersion. Bacteriostatic and bactericidal ingredients released from special coating of metal surfaces prevent orthopedic surgery infection. OBJECTIVE:To prepare hydroxyapatite/nano-silver composite coating on the surface of medical titanium based on different preparation parameters and to observe the release properties of silver ions on the composite material surface in the simulated body fluid. METHODS:Using pulse electrochemical methods, hydroxyapatite and nano-silver were deposited in the solution containing silver, calcium and phosphate ions. Scanning electron microscopy, X-ray diffraction and energy dispersive spectroscopy were used to characterize its morphology and composition. The composite titanium materials containing 0.5, 1 mmol/L silver were immersed in the simulated body fluid, and Ag+concentration was detected by atomic absorption spectrometry at the different time points. RESULTS AND CONCLUSION:Nanoparticles were uniformly distributed in the coating which was interwoven with the nano needle-like hydroxypatite and dot-like silver particles. After high temperature processing, the coating became denser, and hydroxypatite became more crystal and silver particles exhibited no agglomeration. In the simulated body fluid, Ag+release was maximal at 1-7 days and became stable at 7-30 days which maintained an effective antimicrobial concentration. The material containing 0.5 mmol/L Ag+showed a lower amount of Ag+released than cytotoxic concentration at 30 days, but the material containing 1 mmol/L Ag+could release the total of Ag+close to the critical value of celltoxicity at 30 days. Above al , the material containing 0.5 mmol/L Ag+is more secure in the clinical application.

OBJECTIVE:To investigate the effects of Danshen chuanxiongqin injection combined with hyperbaric oxygen on the prevention of early complications in patients with acute spinal cord injury (ASCI).METHODS:A total of 89 ASCI patients were divided into control group (n=44) and combination group (n =45) according to random number table.Control group received routine symptomatic treatment combined with hyperbaric oxygen therapy.Combination group was additionally given Danshen chuanxiongqin intravenous injection 10 mL added into 250 mL 0.9% Sodium chloride injection intravenously,bid,on the basis of control group.Both group was treated for 2 weeks.The changes of spinal cord function recovery index (Botsford score,FIM score),coagulation indexes [prothrombin time (PT),activated partial thromboplastin time (APTT)],hemodynamic indexes (high-shear blood viscosity,plasma viscosity,erythrocyte aggregation indexes) and inflammatory indexes [D-dimer (D-D),C reactive protein (CRP)] were compared between 2 groups before and after treatment.After 1 month of follow-up,the incidence of early complications as deep venous thrombosis and pulmonary embolism were compared between 2 groups.RESULTS:Two cases lost in control group and three cases lost in combination group;42 cases were included in each group.Before treatment,there was no statistical significance between these indexes between 2 groups (P>0.05).After 2 weeks of treatment,Botsford score,FIM score,PT and APTT of 2 groups were enhanced significantly compared to before treatment;high-shear blood viscosity,plasma viscosity,erythrocyte aggregation indexes,D-D,CRP level were decreased significantly compared to before treatment;each index of combination group was significantly better than those of control group,with statistical significance (P<0.05 or P<0.01).The incidence of early complications in combination group was 16.7%,which was significantly lower than 35.7% in control group,with statistical significance (P<0.05).CONCLUSIONS:The application of Danshen chuanxiongqin injection combined with hyperbaric oxygen in the clinical treatment of ASCI can effectively reduce the risk of deep venous thrombosis,pulmonary embolism and other early complications.It has positive effects on alleviating inflammatory reactions,promoting blood microcirculation and improving prognosis of patients.

OBJECTIVETo clarify the role of endothelial cells (ECs) injury induced by anti-endothelial cell antibody (AECA) in allogeneic hematopoietic stem cell transplantation (allo-HSCT).
METHODSSerum immunoglobulin (IgG) from allo-HSCT recipients were purified and incubated with human umbilical vein vascular endothelium (HUVEC) in vitro, then the functional changes and cell apoptosis were tested.
RESULTSAfter incubation with AECA positive IgG, soluble adhesion molecules significantly elevated in culture supernatant. When concentration of IgG was 160, 320, and 640 μg/ml, concentrations of soluble intercellular adhesion molecule-1 in supernatant were statistically higher in AECA positive groups [(117.10 ± 12.82) vs (78.17 ± 4.90) pg/ml, (151.30 ± 15.35) vs (89.46 ± 6.02) pg/ml, (239.00 ± 32.53) vs (127.80 ± 13.86) pg/ml, P<0.01)]. When concentration of IgG was 40, 80, 160, 320, and 640 μg/ml, concentrations of soluble vascular cell adhesion molecule-1 in supernatant were also statistically higher in AECA positive groups [(38.51 ± 3.76) vs (24.78 ± 2.59) pg/ml, (61.34 ± 6.99) vs (38.20 ± 3.17) pg/ml, (135.60 ± 24.46) vs (63.73 ± 5.08) pg/ml, (221.30 ± 29.40) vs (112.80 ± 8.91) pg/ml, (420.90 ± 31.70) vs (224.40 ± 20.79) pg/ml, P<0.01]. Clotting activity factors also elevated in culture supernatant after incubation with AECA positive IgG. When concentration of IgG was 80, 160, 320, and 640 μg/ml, concentrations of von Willebrand factor were statistically higher in AECA positive groups [(19.51 ± 0.72) vs (17.17 ± 0.60) ng/ml, P=0.0193; (22.97 ± 1.18) vs (18.27 ± 0.61) ng/ml, (26.40 ± 1.54) vs (19.53 ± 0.70) ng/ml, (34.35 ± 1.60) vs (23.81 ± 0.92) ng/ml, P<0.01]. When concentration of IgG was 320 and 640 μg/ml, concentrations of thrombomodulin were statistically higher in AECA positive groups [(57.50 ± 4.50) vs (40.31 ± 4.39) pg/ml, P=0.0132; (59.18 ± 4.11) vs (38.84 ± 5.16) pg/ml, P<0.01]. However, inflammatory factors (IL-1β, IL-6, IL-8 and ANG2) were not statistically different in AECA positive and negative groups (P>0.05). Moreover, IgG from AECA positive samples did not change the proliferation or cell apoptosis.
CONCLUSIONAECA from allo-HSCT recipients dysregulates ECs' function in vitro, but do not induce apoptosis, which is valuable in the pathophysiology of graft-versus-host disease (GVHD) and other complications after allo-HSCT.
