BACKGROUND:The type AO-C1 thoracolumbar acute spine injury is a kind of high-energy instable injury, can cause thoracolumbar fracture-dislocation, and mainly associated with spinal nerve injury. Generaly, al needs to posterior open reduction, decompression, bone graft fusion and multiple-segmental internal fixation of pedicle screw rod system, which causes excessive loss of spinal movement segment and a large number of application of internal fixators. OBJECTIVE:To evaluate the treatment effect of posterior pedicle screw mono-segmental internal fixation for treatment of the type AO-C1 thoracolumbar vertebrae fracture-dislocations. METHODS:From January 2008 to December 2013, 17 cases of type AO-C1 thoracolumbar fracture-dislocation were folowed up. Al patients were treated with one-stage posterior open reduction and pedicle screw-rod fixation. Of them, eight cases received four screws and two rods for single-segment fixation in upper and lower vertebrae adjacent to intervertebral space after dislocation (4-screw 2-rod group). Nine cases received eight screws and two rods for multiple-segment fixation in the upper and lower vertebrae adjacent to intervertebral space after dislocation (8-screw 2-rod group). Operative time and intraoperative blood loss were compared between the two groups. The Cobb’s angle was measured on lateral X-ray film of two groups preoperatively and 1 week postoperatively and during the final folow-up. The neurological function was evaluated by Frankel classification. The visual analogue scale was adopted to assess the degree of low back pain. RESULTS AND CONCLUSION:Patients were folowed up for 1 to 5 years. Significant differences were detected in the operative time between the two groups, and operative time was better in the 4-screw 2-rod group than in the 8-screw 2-rod group (P < 0.05). No significant difference was found in intraoperative blood loss between the two groups. The deformity of fracture-dislocation had been corrected, and the pain of low back had significantly relieved in al patients after fixation. According to Frankel classification, two cases at Grade A were improved to Grade E, but eight cases at Grade A got no improvement after treatment. Two cases at Grade B were also improved to Grade E at the final folow-up. Significant differences in Cobb’s angle and visual analogue scale were detectable at 1 week postoperatively and during final folow-up as compared with preoperatively (P < 0.05), but no significant difference was visible between final folow-up and 1 week postoperatively. No significant difference in Cobb’s angle and visual analogue scale was observed between the 4-screw 2-rod group and 8-screw 2-rod group. Results indicate that there was no significant difference in the clinical efficacy between 4-screw 2-rod single-segment and 8-screw 2-rod multiple-segment fixation for treating type C1 thoracolumbar vertebrae fracture-dislocation. Therefore, AO-C1 thoracolumbar vertebrae fracture-dislocation could be treated with 4-screw 2-rod single-segment reduction fixation.

Objective To investigate the expression and clinical significance of mammalian sterile 20-like kinase 1 (MST1) in cervical cancer. Methods Immunohistochemical method was applied to detect the expression level of MST1 protein in specimens of cervical cancer tissues (n=139) and pericarcinomatous tissues (n=20, with≥4 cm distance from the primary tumor's edge). Western blot assay and qPCR were used to detect the protein and mRNA transcription expression levels of MST1 in 20 pairs of cervical cancer tissues and pericarcinomatous tissues, respectively. The correlation between MST1 expression, clinic pathological features and the prognosis were analyzed. Results MST1 was mainly expressed in cytoplasm. The positive expression rate of MST1 was significantly lower in cervical cancer tissues (27%, 38/139) than that in pericarcinomatous tissues (80%, 16/20,χ2=21.62, P<0.01). The expressions levels of MST1 protein and mRNA were both lower in the cervical cancer tissues (P<0.01). In cervical cancer, the positive expression rate of MST1 inⅠb+Ⅱa stage was higher than that ofⅡb+Ⅳstage (P<0.05), the positive expression rate of MST1 in lymph node metastasis was lower than that of without lymph node metastasis (P < 0.05). Values of age, tumor size, histological type and differentiation degree showed no significant difference to positive expression rate of MST1. Moreover, the negative expression of MST1 displayed a significantly poorer overall survival time than that of positive expression of MST1 (Log-rank χ2=28.35, P < 0.01). Conclusion MST1 shows a lower expression in cervical cancer, which may be a new target for clinical treatment and prognosis of cervical cancer.

A thermal desorption ( TD) device was developed and coupled to gas chromatography ( GC) or gas chromatography-mass spectrometry ( GC-MS ) for the qualitative and quantitative analysis of semi-volatile organic compounds on atmospheric particulate matters ( PM ) . The TD was operated by direct heating and placed on the GC injector, leading to high heating rate and easy transfer of analytes to GC without focusing of analytes by cold trap. For establishing the TD-GC method, the materials used for supporting PM samples, temperature and time of thermal desorption, and types of sample injection were investigated for detection of sixteen polycyclic aromatic hydrocarbons ( PAHs) and nine n-alkanes. The limits of detection of the proposed TD-GC method were in the range of 0. 014-0. 093 ng for PAHs, and 0. 016-0. 026 ng for n-alkanes, respectively, with the correlation coefficients of correlation above 0. 9975. The TD-GC method was applied to the determination of trace PAHs and n-alkanes on PM10 samples from three cities. The recoveries were in the range of 95%-135% ( PAHs) and 95%-115% ( n-alkanes) , respectively. Finally, the TD was coupled to GC-MS for comparison of the contents of PAHs and n-alkanes on PMx with different particulate size ( x=10 , 5, 2, 1, 0. 5, 0. 25, 0. 1).

Objective:
To investigate the effects of 12-week high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on body composition, arterial stiffness(cfPWV) and serum resistin level in the obese college female students, so as to provide a theoretical reference for improving the cardiovascular health of obese college students and seeking better ways of losing weight.
Methods:
Thirty-seven female college students were chosen and then randomly assigned to HIIT group(n=19), MICT group(n=18). The subjects in both the HIIT group and MICT group underwent exercise for 12 weeks(five times per week). Then body composition and resistin level were measured, arterial stiffness by carotid-femoral pulse wave velocity (cfPWV) was evaluated in all subjects before and after training.
Results:
After 12-week exercise, body weight, BMI, body fat and trunk fat significantly decreased in both HIIT and MICT groups (t=2.19, 6.02, 2.64, -2.76, P<0.05); muscle mass significantly increased, serum resistin level and cfPWV significantly decreased (P<0.01) only in HIIT group. Compared with the MICT group, trunk fat, cfPWV, serum resistin level were lower and muscle mass was higer in HIIT group(P<0.05), while the reduction of serum resistin level before and after the intervention of HIIT was positively correlated with the reduction in the trunk fat and cfPWV, and negatively correlated with the increases in the muscle mass(r=0.52, 0.56, -0.65, P<0.01).
Conclusion
Both HIIT and MICT have favorable effects on body composition in obese college female students. However, HIIT is more beneficial for improving the trunk fat and arterial stiffness than MICT group which may be associated with decreases in serum resistin level.

Ex-vivo liver resection and liver autotransplantation offers a chance to cure extensive regional liver diseases which are otherwise deemed untreatable in selected cases. A 33-year-old male patient with advanced alveolar echinococcosis (AE) which invaded the right lobes and adjacent retrohepatic inferior vena cava, while the left lobes were free from lesion and had proliferated to over 1200 ml in size except for a 1 cm × 1 cm solid lesion in the segment Ⅳ. No extrahepatic metastases were found in this patient. A lesion with a size of 4300 ml and other small lesions in the right lobes were removed extracorporeally,and the retrohepatic vena cava was repaired, then the remaining AE-free left lobes (more than 700 ml in size) and the retrohepatic inferior vena cava were re-implanted in situ. A temporary end-to-end cavo-caval shunt with interposition of a blood vessel prosthesis and end-to-side portocaval shunt were established to keep the blood flow during the four-hour anhepatic phase. The patient was followed up for six months, and he had no signs of residual liver disease with good hepatic function.
