Objective To evaluate the clinical outcome of mono-segment transpedicular fixation of type B thoracolumbar fracture.Methods A retrospective analysis was conducted on 40 cases suffering from type B thoracolumbar fracture treated with mono-segment transpedicular fixation from May 2003 to October 2012.According to the AO classification,13 cases were identified with type B1.1,11 type B1.2,11 type B2.2,2 type B3.1,2 type B3.2,and 1 type B3.3.Radiological results were evaluated by measuring compression rate of the fractured vertebra and Cobb' s angle of the vertebra adjacent to the fractured segment.Clinical results were assessed using Frankel classification for spinal cord injury and visual analogue scale (VAS) for pain.Results Mean operation time was 71 minutes and mean intrao perative blood loss was 105 ml.Mean period of follow-up was 47.5 months (range,24-82 months).Mean Cobb' s angle of the vertebra adjacent to the fractured segment and compression rate of the fractured vertebra revealed great correction at one week post-operation compared with preoperative ones (6.2° vs 20.1° and 10.1％ vs 38.9％ respectively,P ＜0.05) and there was no significant correction loss at the last follow-up (6.9° and 10.8％ respectively,P ＞ 0.05).Mean VAS was 8.6 points before operation,but mean VAS was 2.4 points at final follow-up (P ＜ 0.05).Neurological performance improved in 37 cases (93％).No cases experienced neurological deterioration.Conclusions Mono-segment transpedicular fixation has small incision,short operation time,few bleeding and decreased motor function loss.The procedure is indicated for most type B thoracolumbar fracture and clinical results are satisfactory.

BACKGROUND:Whether controling of post-injury inflammatory response combined with neural stem cel (NSC) transplantation can improve the curative efficacy for spinal cord injury stil remains unclear. OBJECTIVE:To investigate the repair of spinal cord tissue, myelin regeneration, axon regeneration, motor function recovery and the possible mechanism after early application of tumor necrosis factor α antagonist (Etanercept) combined with tyrosine kinase C (TrkC) gene-modified NSC transplantation. METHODS:TrkC-overexpressed NSCs (TrkC-NSCs) were constructed by lentiviral transfection technique. The rat models of spinal cord transection injury were prepared, and then subjected to Etanercept combined with TrkC-NSCs transplantation. The number of neurons and neuroregeneration after injury were measured by Nissl's staining, immunofluorescence and western blot. The rat motor function was detected by Basso Beattie Bresnahan score and evoked potential. The myelin regeneration was detected by electron microscopy and toluidine blue staining. RESULTS AND CONCLUSION:Compared with the other groups, the Etanercept combined with TrkC-NSCs transplantation group had more survived anterior horn motor neurons at 28 days after injury, more myelin-encapsulated axons, higher Basso Beattie Bresnahan score, greater amplitude of the evoked potentials, and relatively shorter latency (alP < 0.05). These findings indicate that early application of tumor necrosis factor-α antagonist combined with TrkC-NSCs transplantation after spinal cord injury in rats can effectively promote myelin regeneration, axon regeneration, and further promote motor function recovery.

Objective To investigate the feasibility of mono-segment pedicle instrumentation (MSPI)in management of thoracolumbar fracture (AO classification,A1 and A3) by being compared with short-segment(two-segment) pedicle instrumentation(SSPI).Methods Overall 141 patients with tape A1 or A3 thoracolumbar fractures,aged from 20 to 60 years (average,40.5 years),were enrolled in this prospective study.According to a simple randomized method,35 patients with type A1 fracture and 41 patients with type A3fracture were treated with MSPI,while 26 with type A1 fracture and 39 with type A3 fracture were treated with SSPI.Low back outcome score (LBOS) and ASIA2000 were used to evaluate clinical outcome.Eighteenth month postoperatively was assigned as the last follow up period.Wedge index (WI) and sagittal index (SI) of the affected vertebrae on radiography were measured and compared preoperatively,one week postoperatively and at the final follow-up.Results All patients were followed up successfully.The blood loss and duration of operation of MSPI group were significantly less than that of SSPI group,respectively.However,there were no significant differences of clinical outcome between two groups.For type A1 fracture,correction rate and correction loss of WI in MSPI group were better than those in SSPI group.For type A3 fracture,there were no significant differences of correction rate and correction loss of WI and SI between MSPI group and SSPI group; however,the failure rate of MSPI group was significantly higher than that of SSPI group.Conclusion For type A1 and partial type A3 thoracolumbar fractures,MSPI can provide the same or better fixation with less blood loss and operative duration than SSPI.Since MSPI for type A3.2 thoracolumbar fracture has a higher failure rate,the surgical indication should be strictly controlled.

Objective To learn the effect of different combination model between irradiation and cisplatin or lobaplatin on the radiosensitization of xenographt tumor in mice.Methods Seventy C57BL/6 mice with Lewis lung carcinoma were randomly divided into fourteen groups.Then a single intravenous bolus injection of 10 mg/kg either cisplatin or lobaplatin was given.Tumor tissues were collected at the indicated times of 0.5 h, 2.0 h, 4.0 h, 24.0 h, 48.0 h, 72.0 h, and 96.0 h.The platinum levels were determined by inductively coupled plasma-mass spectrometry.Eighty tumor-bearing mice were randomly divided into 10 groups, including a blank control group, a irradiation group, two drug treatment groups and 6 combined treatment groups.The tumors were irradiated at 1 h, 24 h or 72 h after either cisplatin or lobaplatin injection.The tumor size of the groups was compared.Results The concentrations of cisplatin and lobaplatin in tumors rapidly reached 4.78 μg/g and 2.79 μg/g (t=3.82,P=0.005), respectively, then declined rapidly to 3.39 μg/g and 0.99 μg/g (t=9.10,P=0.000) at 4 h, 1.41 μg/g and 0.23 μg/g (t=3.70,P=0.006) at 96 h, respectively.The tumor growth among the three groups of irradiation at 1 h, 24 h or 72 h after cisplatin was similar, which was slower than the blank control group, the irradiation group and the cisplatin treatment group.At the 15th day, the relative volume of tumor in the three combined treatment groups were 4.73, 5.52 and 2.15(F=0.84,P=0.451), While was 16.63(F=10.50,P=0.000) in the blank control group, 10.34(F=3.12,P=0.046) in the irradiation group, and 12.80(F=8.06,P=0.001) in the cisplatin treatment group, respectively.The tumor growth among the three groups of irradiation at 1 h, 24 h or 72 h after lobaplatin was also similar, which was slower than the blank control group, the irradiation group and the lobaplatin treatment group.At the 15th day, the relative volume of tumor in the three combined treatment groups were 3.49, 4.90 and 3.86(F=0.32,P=0.727), While was 16.63(F=15.21,P=0.000) in the blank control group, 10.34(F=4.12,P=0.016) in the irradiation group, and 14.28(F=10.67,P=0.000) in the lobaplatin treatment group, respectively.The sensitizing enhancement ratio (SER) at 1 h, 24 h and 72 h after the injection were 2.13, 2.03 and 3.45 of cisplatin, and 2.53, 2.00 and 2.50 of lobaplatin, respectively.Conclusions After intravenous bolus injection, the cisplatin concentration in the tumor can be kept at least 96 hours, which results in a persistent radiosensitizing effect.Lobaplatin and cisplatin have similar anti-tumor and radiosensitizing effect.

Objective To analyze the survival and prognostic factors in the treatment of angiosarcoma. Methods A retrospective study was performed on clinical data of 30 patients pathologically diagnosed with angiosarcoma who were admitted to our hospital from 1988 to 2015 and had complete follow?up data. In those patients, 18 patients received comprehensive treatment, containing 9 patients treated with surgery plus radiotherapy, 4 patients with surgery plus chemoradiotherapy, and 5 with surgery plus chemotherapy;12 patients received non?comprehensive treatment, containing 11 patients treated with surgery alone and 1 patient radiotherapy alone. The survival rates were calculated using the Kaplan?Meier method and analyzed using the log?rank test. The Cox regression model was used for multivariate prognostic analyses. Results The 1?, 2?, and 5?year sample sizes were 29,26, and 18, respectively. The 1?, 2?, and 5?year overall survival ( OS) rates were 70?1%, 49?1%, and 40?9%, respectively;the 1?, 2?, and 5?year local relapse?free survival rates were 52?8%, 44?0%, and 35?2%, respectively;the 1?, 2?, and 5?year distant metastasis?free survival rates were 81?6%, 68?0%, and 56?7%, respectively. The multivariate analysis showed that tumor site, tumor size, staging, and visible tumor residue after initial treatment were prognostic factors for OS ( P= 0?027, 0?027, 0?011, 0?000 );In the patients with stage Ⅰ or Ⅱ disease, the comprehensive treatment achieved a significantly lower local?relapse rate than the individual treatment ( P=0?006);gender, age, staging, and tumor site were prognostic factors for distant metastasis ( P=0?028, 0?011, 0?015, 0?022 ) . Conclusions Early diagnosis and early treatment are recommended for angiosarcoma, which has high local recurrence and distant metastasis rates. Comprehensive treatment ( surgery plus radiotherapy and/or chemotherapy) is recommended for patients with stage Ⅰ or Ⅱ disease. Tumor site, tumor size, staging, and visible tumor residue after initial treatment are prognostic factors.

Objective:To explore the amplitude of normal kidney motion in the 3D direction and its influencing factors under free-breathing condition.Methods:Clinical data of 28 patients with a KPS score≥80 who received 4D CT scan from March 2018 to March 2019 were collected. All patients were diagnosed with liver, pancreatic or lung tumors. The kidney was outlined and the geometric center and 3D coordinate values were recorded. The motion of bilateral kidneys in each direction and the 3D direction was calculated. The volume of kidney and surrounding organs, age, sex, height and body mass index (BMI) were recorded. Clinical data were statistically compared by t-test or nonparametric test. Results:The motion of the left and right kidneys in the the sup-inf (SI) direction were the largest up to (8.39±3.18) mm and (7.71±3.55) mm. The motion amplitudes of bilateral kidneys in male patients were significantly larger than those of the female counterparts in the left-right (LR), SI and 3D directions (all P<0.05). The motion amplitudes of bilateral kidneys in patients taller than 165 cm were significantly larger than those of their counterparts with a height of ≤165 cm (all P<0.05). Patients with a BMI≥25 kg/m 2 had significantly larger motion amplitudes of the left kidney in the LR and ant-post (AP) directions compared with those of normal weight counterparts (all P<0.05). The motion amplitude of the left kidney in the AP direction in patients with the left kidney volume of >180 cm 3 was significantly larger than that of patients with smaller left kidney volume ( P=0.014). Age was not significantly associated with kidney motion in each direction ( P>0.05). Conclusions:Kidney motion mainly occurs in the SI direction. The kidney motion amplitudes in male and taller patients are larger. Special attention should be paid to the use of breath motion control device to decrease the normal tissue damage.
