Objective To report our clinical outcomes of treating tibial defects combined with soft tissue defects using Ilizarov technique.Methods From May 2010 to February 2015,52 patients with combined bone and soft tissue defects of the tibia were treated at our department.They were 41 males and 11 females,aged from 19 to 65 years (average,37.7 years).By Gustilo classification,49 cases were type ⅢB and 3 type ⅢC.The areas of soft tissue defect ranged from 7 cm ×3 cm to 28 cm × 15 cm,and the tibial defects ranged from 5 cm to 15 cm in length (average,12.6 cm).The schemes of Ilizarov technique depended on the location and size of the tibial defects.Open wound dressing combined with bone transport was adopted in 21 cases,limb shortening followed by bone lengthening with compression at the fracture ends in 12 cases,and tissue flap transplantation combined with bone transport or lengthening in 19 cases.Results The follow-up time of the 52 patients ranged from 13 to 61 months (average,27.1 months).The distance of bone transport or lengthening ranged from 5.0 cm to 13.6 cm (average,10.8 cm);the bone transport speed averaged 0.81 mm/day.The tibiae united in all the 52 patients;the time for external fixation ranged from 13 to 21 months (average,15.3 months);the external fixation index was 2.3 months/cm.According to the Paley functional criteria,23 cases were excellent,19 good,9 fair,and one poor,yielding an excellent to good rate of 80.7％.Conclusion According to the location and size of the bone and soft tissue defects of the tibia,the 3 schemes of Ilizarov technique can be rationally chosen to obtain fine clinical outcomes.

Objective To explore the expression of tissue inhibitor of metalloproteinases-2(TIMP-2) in peripheral blood lymphocytes in patients with chronic obstructive pulmonary diseases(COPD) and the association of smoking and TIMP-2 mRNA. Methods The expression of TIMP-2 mRNA in peripheral blood lymphocytes was measured by reverse transcription-polymerase chain reaction(RT-PCR) in 44 patients with COPD and 42 healthy smokers.The correlation analysis was then conducted between TIMP-2 mRNA expression and smoking index. Results The expression of TIMP-2 mRNA was 0.753?0.154 and 1.170?0.196,respectively,in patients with COPD and healthy smokers(P

Objective To observe hypoxia-induced pulmonary arterial endothelial-to-mesenchymal transition and investigate the role of transforming growth factor β1 (TGF-β1) in the process. Methods Pulmonary arterial cells improved by adherence method were cultured in normoxia (containing 21%O2,5%CO2 and 74%N2) or hypoxia (containing 1%O2,5%CO2 and 94%N2) for 1,4,or 7 days,respectively. Endothelial-to-mesenchymal transition was confirmed with morphological observation and expression of α-smooth muscle actin (α-SMA) by immunocytochemistry. Expression of TGF-β1 was evaluated by RT-PCR and Western blot,and α-SMA by Western blot. Results Hypoxia-induced paving-stone-like pulmonary arterial endothelial cells transdifferentiating to polygonal cells with high-expression of α-SMA. TGF-β1 expression was increased significantly after 7 days of hypoxia. TGF-β1 stimulating alone increasedα-SMA expression of pulmonary arterial en-dothelial cells;while,SD-208,inhibitor of TGF-β1,abolished the above effect. Conclusion Hypoxia can induce endothelial-to-mesenchymal transition. And TGF-β1 plays an important role in the process.

OBJECTIVE:To observe the effect of Compound glycyrrhizin on serum VEGF of patients with alopecia areata. METHODS:36 alopecia areata patients were selected as trial group and treated with Compound glycyrrhizin(50 mg/time,3 times/d) for 3 months. Double-antibody sandwich ELISA method was adopted to determine the content of VEGF in serum before and after treatment. 36 healthy volunteers were included in control group,and serum content of VEGF in control group was compared with trial group. RESULTS:Compared with control group,the serum content of VEGF was lower in trial group,with statistical signifi-cance(t=5.863,P<0.05). After treatment,the serum VEGF levels of trial group increased,with statistical significance(t=4.351, P<0.05);there was no statistical significance in VEGF levels between trial group and control group after treatment(t=1.678,P>0.05). CONCLUSIONS:Compound glycyrrhizin can cure alopecia areata through increasing serum level of VEGF.

Objective To investigate bone age of left-hand wrist in healthy adolescents of Shenyang and Beijing for assessing the process of skeletal development.Methods From 2008 to 2012,1333 adolescents (aged form 4.0 to 18.0 ys) of Shenyang and Beijing were enrolled in this study.Skeletal age was estimated by left hand and wrist X-ray using CHN atlas by 2 qualified radiologists.The correlation between skeletal and chronological age was analyzed using correlation analysis.Skeletal age and chronological age were compared using paired t test.The differences between skeletal and chronological age in genders and regions were compared using independent-samples t test.SPSS for Windows (version 13.0)was used for statistical analysis.P ＜ 0.05 was considered as significant difference.Results (1) Close correlation was found between skeletal age and chronological age (P ＜ 0.01) for both two genders and two regions.(2)Among 28 groups of investigation,16 groups (boys,11 groups) had higher skeletal ages than chronological ages with statistical significance,including Shenyang boys aged 6.0-18.0 ys,Shenyang girls aged 6.0-7.9 ys and 14.0-15.9 ys,Beijing boys at 6.0-15.9 ys and Beijing girls at 8.0-13.9 ys.(3) Comparison between boys and girls:5 groups showed significant difference,including 8.0-9.9 ys,10.0-11.9 ys and 16.0-18.0 ys groups in Shenyang and 6.0-7.9 ys,10.0-11.9 ys groups in Beijing.(4) Comparison between Shenyang and Beijing:6 groups showed statistical significance,including boys at 10.0-11.9 ys,12.0-13.9 ys and 16.0-17.9 ys and girls at 6.0-7.9 ys,8.0-9.9 ys and 10.0-11.9 ys.Conclusion Although CHN atlas method could reflect adolescent bone development,the skeletal age is higher than chronological age in many groups,and the difference between skeletal and chronological age is statistically different between genders and between two regions.This research can be used as a reference for the study of skeletal development and for further emendation of CHN atlas.
