Objective　The topographic relationship between the external laryngeal nerve(ELN) and the superior thyroid artery (STA) were observed, in order to provide the anatomical foundations for protecting the ELN during surgery.　Methods　 Fifty-seven cadavers (114 sides) fixed with formalin were collected at random. The ELN and STA were carefully dissected and analyzed under a 6-power magnifier.　Results　The cervical sympathetic chain (CSC) of 90 sides was anastomosed with the ELN（CSC-ELN loop). For the 27.7% (25 sides) low-position CSC-ELN loops observed, the neurovascular relationship between the STA and ELN was classified into four types: ①the branches of the STA overlapped with the CSC-ELN loop; ② the glandular branch of the STA passed through the CSC-ELN loop; ③the muscular branch of the CSC-ELN loop and the laryngeal branch of the STA coursed together;④the branches of the STA and the CSC-ELN loop were interlaced.　Conclusion　Our study has shown a variable morphology of the CSC-ELN loop and its complicated topographic relationship to the STA, which should be kept in mind when attempting to avoid the nerve injury. Two special surgical procedures are recommended. First, the vessels should be individually isolated and then ligated during thyroidectomy. Second, a special attention should be paid to protect the coricothyroid branch of CSC-ELN loop from injury, when the anteriomedial branches of the STA are to be ligated during larynx surgery.

Objective　To compare the difference of the time-validity of repairing and the fluorescence stability between BMSCs infected by a lentiviral vector carrying GFP and the BMSCs in GFP rats in treatment of hepatic ischemia reperfusion injury. 　Method　The two kinds of BMSCs were cultured and the method of MTT was used to detect the differences of the two cell growth curves. Healthy SD rats were randomly divided into a sham operation group、a lentiviral transfection GFP group(LV-GFP group)、a GFP transgene group(GFP-BMSCs group) and a model group. After operation, the rats of the LV-GFP group and the GFP-BMSCs group were immediately injected with the corresponding cell suspension of 200 μl (the number of 1×106) by portal vein, and the model group was injected with the same volume of PBS. After 1, 2, 3 and 4 weeks，the levels of AST、ALT and ALB were tested by the blood sampling in different groups. From 1 to 5 days after operation, the hepatic tissue from the experience groups were transected to observe the migrating of the GFP positive cells in the liver; At  week 4, the hepatic tissue was transected from the experience groups to detect the fluorescence stability of the BMSCs and its expression of the keratin 18 (CK18) in the liver.　Results　The proliferation of the BMSCs in GFP rats was significantly stronger than that of BMSCs infected by a lentiviral vector carrying GFP in logarithmic phase. At weeks 1 and 2, the levels of the aspartate amino transferase (AST) and alanine amino transferase (ALT) in GFP-BMSCs group were lower than those in LV-GFP group (P<0.05), and the level of serum albumin (ALB) in GFP-BMSCs group was higher than that in LV-GFP group at  weeks 2 and 3 (P<0.05). BMSCs labeled GFP in hepatic lobules were successively found in the GFP-BMSCs group and the LV-GFP group on the third and 5th day, respectively. The hepatic cells from BMSCs cells in the liver were found in the GFP-BMSCs group and the LV-GFP group at week 4 after operation, but the fluorescence intensity in GFP-BMSCs group was better than that in LV-GFP group.　Conclusion　The BMSCs in GFP rats show the better time-validity of repairing and fluorescence stability than the BMSCs infected by a lentiviral vector carrying GFP in treatment of hepatic ischemia reperfusion injury.

Objective　To study therapeutic effect of rat nerve growth factor (NGF) on rabbit tibial nonunion treatment and provide a reference for its clinical application.　Method　40 healthy adult male New Zealand white rabbits underwent establishment of transverse fracture nonunion model about 3~5 cm under the right tibial tuberosity，and were divided randomly and equally into the experimental group and the control group：the experimental group received injection of NGF at the fracture site once a week for 12 weeks; the control group received injection of normal saline at the fracture site once a week for 12 weeks. Both groups received X-ray and histological observation in the same time to observe callus growth and bone healing during the experiment.　Results　In the experimental group, callus appeared in (2.0±0.5) weeks, the fracture line became blurred in (8.2±1.2) weeks, and bone healed in (12±1.7) weeks; in the control group, callus appeared in more than 8 weeks, no fracture line became blurred or bone healed. Fracture healing in the experimental group was much better than that in the control group. According to the statistics processing,the difference had statistical significance(P<0.05). 　Conclusion　NGF has a strong promotion of bone nonunion callus growth and healing, and its broad application prospect in the clinical treatment of nonunion might be viewed.

Objective　To analyze biomechanical characteristics of pedicle screws and lumbar under different pressure loads between unilateral and bilateral pedicle screw fixation plus interbody fusion after discectomy by creating a normal L4~5 spinal segment finite element model.　Methods　A three-dimensional finite element model was created by using CT sectional images of an intact L4~5 segment of a healthy male and then model A and model B were established. Model A was unilateral pedicle screw fixation plus interbody fusion after lumbar discectomy, and model B was bilateral pedicle screw fixation plus interbody fusion after lumbar discectomy. The lumbar variation, the changes of lumbar stress and the apex stress of pedicle screw under flexion, extension, left/right lateral bending and left/right rotation were observed in the two models.　Results　The maximum displacement and stress of pedicle screws in model A reached max under the operating models of fixed-side flexion，and the maximum stress of lumbar reached max under extension. While in model B the maximum displacement reached max under extension,and the maximum stress of screws and lumbar reached max under rotation. There was significant difference between model A and B under fixed-side flexion and extension. 　Conclusion　Compared with bilateral and unilateral fixation plus fusion, the possible potential risk of instability, screw loosening and metal breakage of unilateral fixation plus fusion was greatly increased. The movement of extension, fixed-side flexion and rotation should be reduced before bone union after unilateral fixation plus fusion.

Objective　To discuss impact of graft height on zygapophyseal joint pressure and range of motion of adjacent segments following the cervical anterior fusion and to guide the choice of optimal graft height in clinic.　Methods　Eight fresh-frozen human cadaveric cervical spines were used in this series, specimens were tested in five conditions, normal(specimens with intact discs)and different graft height(120％,140％,160％of mean height) after Smith-Robinson discectomy between the fifth and sixth cervical vertebrae.Each specimens were subjected to flexion-extension. Lateral bending and axial rotation in material test system(BOSE ELECTROFORCE) were adopted to measure zygapophyseal joint pressure and rotation of the fourth to fifth segments and the sixth to seventh segments. Finally, The data for each state was used to determine the statistical significance of differences.　Results　The height of bone graft had little effect on the zygapophysial joints pressure values in neutral position with no statistical significance noted among each groups(P>0.05); The zygapophysial joints pressure value was the highest increase in extension position,but 120%M increased minimum of zygapophysial joints pressure value, and statistical significance were noted among each groups（P<0.05); the zygapophysial joints pressure value increased in various degrees under flexion and rotation positions, and statistical significance were noted among each groups（P<0.05）; but 120%M  increased minimum of zygapophysial joints pressure value.The range of motion at the upper and lower adjacent segments were not significantly changed between 120%M and complete condition (P>0.05), and statistical significance were noted in others groups（P<0.05）;The range of motion at the upper and lower adjacent segment  were not significantly changed among each groups (P>0.05).　Conclusion　The appropriate graft height after single discectomy may be 120％mean height.

Objective　To measure the morphological parameters of patellofemoral joint on MRI and analyze the etiological correlation between patellofemoral morphology and chondromalacia patellae (CP).　Methods　371 adult patients undergoing MRI examination were enrolled and those diagnosed with CP were included in the CP group（n=124）and others in the control group（n=247）. Prevalence rates of CP were recalculated and grouped according to gender. The lateral patellofemoral angle, sulcus angle, trochlear depth and lateral trochlear inclination angle were measured in the MRI images on axial slices. The CP group was further divided into a mild and severe CP subgroup according to the degree of cartilage damage. The difference of patellofemoral morphology parameters among the CP group and control group, CP group (mild) and CP group (severe) were compared and the relationships among patella tilt, trochlear dysplasia and CP were further analyzed.　Results　The prevalence rate of CP was 33.42%, of which 49.35%was in women  and  22.12%was in men. Significant differences in the lateral patellofemoral angle (P=0.00), sulcus angle (P=0.00), trochlear depth (P=0.00) and lateral trochlear inclination angle (P=0.02)  could be found in the CP group and control group. However, there were no significant differences between patients in mild CP group and severe CP group in the lateral patellofemoral angle, sulcus angle, trochlear depth and lateral trochlear inclination angle（all P>0.25）. Considered gender or not, patellar tilt and trochlear dysplasia were significant correlated with chondromalacia patellae（P=0.00）.　Conclusion　Patellar tilt and trochlear dysplasia are significantly correlated with CP but not the degree of CP.

Objective　To evaluate the safety and feasibility of the application of bronchial occluder in the right lobe one-lung ventilation in thoracic surgery.　Methods　From July 2012 to August 2013, 36 consecutive patients who need the right lobe one-lung ventilation in thoracic surgery were enrolled and were randomly divided into two groups: group A and group B, 18 cases in each group. The traditional double lumen bronchial method was used in group A and the bronchial occluder was used in group B intubation time. Changes of vital signsbefore and after intubation,the qualityof lung collapse during operation, pH, arterial partial pressure of CO2, partial pressure of oxygen and airway pressure Paw were recorded 20 min, 40 min,and 60 min after intubation or one-lung ventilation. The number of patients with hypoxia in the operation and postoperative complications in each group were also recorded.　Results　The airway pressure in group B was significantly lower than that in group A, and the number of patients with postoperative complications such as hypoxia and postoperative hoarseness was significantly lower (P<0.05).　Conclusion　Bronchialoccluder method could solve intraoperative blood oxygen desaturation caused by the double lumen endobronchial malalignment, and airway irritation was mild. Consequently，it is a safe and effective method for single lung ventilation in the right lobe one-lung ventilation in thoracic surgery.
