Objective To study the value of color Doppler ultrasound in diagnosis of deep vein thrombosis (DVT) of lower extremity and pulmonary embolism (PE) in spinal cord injury (SCI). Methods 60 PE patients (PE group) and 35 SCI patients without PE (control group) received color Doppler ultrasound examination for DVT of lower extremity. Results PE group included 36 SCI patients (PE-SCI group) and 24 no-SCI patients (PE-no-SCI group). There were 15 cases with lower extremity thrombosis in PE-SCI group, and 9 cases in PE-no-SCI group (P>0.05), while there were 5 cases in the control group. There was significantly different in lower extremity thrombosis between PE group and the control group (P<0.01). In PE group, the detection rate was not significantly different between acute PE (detected 11 cases out of 37 cases) and chronic PE (detected 10 cases out of 23 cases) (P>0.05). 31 cases were rechecked as lower extremity venous valve regurgitation and calf muscle vein dilation (51.7%) in PE group while 8 cases in the control group (22.9%) (P<0.01). Conclusion There is not significantly different in the detection rate of DVT of lower extremity in PE patients with and without spinal cord injury, which are higher than in the patients without PE. Color Doppler ultrasound is necessary to check DVT in acute and chronic PE patients.

BACKGROUND: The soft tissues would shrink with nasal framework collapse following surgical trauma, which cause aseptic inflammation, lead to parts of cartilage resorption. Accordingly, long-term saddle nose deformity usually accompanied by short nasal columella. Complications such as skin perforation or ulceration would appear if corrected the deformity using medical silicone rubber with large tension.OBJECTIVE: To explore the effectiveness of repairing post-traumatic saddle nose deformity with autologous costal cartilage transplantation.METHODS: A total of 21 cases with post-traumatic saddle nose deformity accompanied by short nasal columella were selected, including 6 males and 15 females, aged 16 45 years. All of the cases had trauma history and agreed with the treatment. The costal cartilage was obtained from the seventh rib and formed to babylon weeping willow leaf shape and columella nasi stent to repair post-traumatic saddle nose deformity. The "V-Y" progradation suture was used in the philtrum introcession and the botton of nasal columella to extend the nasal columella. The recovery of saddle nose deformity after transplantation, discharge of transplanted cartilage, as well as the incision scar status was observed.RESULTS AND CONCLUSION: The results were satisfactory and there were no complications after transplantation. All the cases were followed up from 6 months to 2 years. No case suffered costal cartilage grafts discharge or chondral deformation. The scar was little at the bottom of nasal columella. It is an ideal method for repairing post-traumatic saddle nose deformity using transplantation of autologous costal cartilage with "V-Y" progradation suture.

Objective To assess the relationship of CYP2C19 gene polymorphism with clopidogrel respon-siveness and the level of EETs in patients with ACS. Methods A total of 123 patients with ACS receiving aspirin combined with clopidogrel dual antiplatelet were enrolled. According to the results of CYP2C19 genotype,patients were divided into three groups:fast metabolic type ,medium metabolic type ,and slow metabolism type. The concentration of EETs and PAIR were compared between three groups. Logistic analysis was used to analyze the risk factors of LCR. Results There were differences statistically in level of EETs and PAIR among the three groups(P<0.05). Logistic analysis showed that the slow metabolism of CYP2C19 gene and lower EETs level were risk factors for LCR. The area under the ROC curve was 0.893(P < 0.05)by EETs level to predict the CYP2C19 genotype. Conclusion The slow metabolism of CYP2C19 gene was an independent risk factor for LCR,while the increase of plasma EETs level was a protective factor.

Objective To conduct an empirical study for quantifying the anastomosis between two vessels after skin expanded technique by the method of angiography and to provide a precise basis for vascular study in skin flap.Methods Bilateral skin flaps based on deep iliac circumflex vessels were elevated from the abdominal wall including deep superior epigastric vessels.One was expanded at the boundary between two vessels and the other unexpanded.An X-ray image was obtained by carotid arterial injection of gelatin-lead oxide mixture.Three parallel lines with equal intervals perpendicular to long axis of the two vessels were designed at the communication area.Vessel anastomosis quantity was determined by counting the number of marks derived from the intersections of the lines and the vessels and statistical analysis was carried out.Results The marks of intersection in expanded group were more than unexpanded group with statistical significance.Conclusions The method for quantifying vessel anastomosis in skin flap is reliable.The principles of this procedure may also be applied to other experimental and elinical studies.

BACKGROUND:Compared with normal physiological flap,main advantage of venous skin flap is that it throws off the limitation of arterial vascular territory on donor site and recipient site of traditional axial skin flap.However,its survival rate is unstable.OBJECTIVE:To explore effects of basic fibroblast growth factor (bFGF)-[poly(lactic-co-glycolic-acid)] (PLGA)-sustained release microspheres on the survival of rabbit venous flaps.DESIGN,TIME AND SETTING:A randomized controlled animal study was performed at the University of South China from May to October 2008.MATERIALS:A total of 24 healthy New Zealand rabbits were equally randomly assigned to bFGF-PLGA sustained release microsphere,blank microsphere and blank control groups.METHODS:The formulation of bFGF microspheres was optimized by orthogonal design.bFGF-PLGA microspheres were prepared by optimized method.Lateral abdominal wall skin flap was created in rabbits from 3 groups.Five days before operation,28.85 g/L bFGF-PLGA microspheres 3 mL (containing bFGF 20 ?g) was intradermally injected into rabbits from the bFGF-PLGA sustained release microsphere group.An equal volume of blank microsphere + bFGF was injected in the rabbits of the blank microsphere group.Rabbits from the blank control group were infused with the same volume of saline.MAIN OUTCOME MEASURES:Morphology and particle distribution of bFGF-PLGA microspheres,drug loading volume,encapsulation efficiency,in vitro drug release characteristics were measured.After seven days,the survival area of skin was determined.Rabbit skin samples received CD34+ immunohistochemical staining to detect the expression of CD34+ and average number of blood vessels.RESULTS:The bFGF microsphere prepared based on optimized formulation exhibited well-defined properties,with the even and uniform sphere in appearance,regular particles without adhesion,about 98% of particles with a size distribution between 12.50 to 43.49 ?m,with a mean particle size of 26.93 ?m and size span of (0.611 ? 6.60).The drug loading volume and encapsulation efficiency of bFGF microsphere reached [(23.11?0.44)?10-3]% and (86.51?0.83)%,respectively.In the burst release phase,the rate of in vitro drug release amounted to 27.78%,but rose to 81.56% accumulatively 30 days later.The in vitro drug release of bFGF microsphere corresponded with Higuichi equation (r=0.997).The sustained-release microspheres,blank microspheres and normal saline group,the average survival of the flap and the average number of blood vessels were similar (P=0.597,P=0.336),but still significantly lower than the bFGF-PLGA sustained release microsphere group (P=0.000).Results of immunohistochemical staining revealed that bFGF-PLGA promoted blood supple between flap and surroundings,improved flap survival and abundant CD34+ expression.CONCLUSION:bFGF microsphere with good morphology,high drug loading volume and encapsulation efficiency can be obtained using W/O/W multiple emulsion evaporation method.The bFGF microsphere can promote the survival of rabbit venous flaps through a long period due to sustained release of bFGF.
