0.05). The median diameter of the nodules in survival group was smaller (4.3?2.2cm)than that in death group(7.3?2.7cm, P0.05). Ten of 14 survived patients remained clinical free of tumor. In conclusion, RFA could extend survival time for patients with unresectable PHC.

The process flow and the main devices of a new two-stage dry-fed coal gasification pilot plant with a throughout of 36 t/d are introduced in this paper. For comparison with the traditional one-stage gasifiers, the influences of the coal feed ratio between two stages on the performance of the gasifier are detailedly studied by a series of experiments. The results reveal that the two-stage gasification decreases the temperature of the syngas at the outlet of the gasifier, simplifies the gasification process, and reduces the size of the syngas cooler. Moreover, the cold gas efficiency of the gasifier can be improved by using the two-stage gasification. In our experiments, the efficiency is about 3%-6% higher than the existing one-stage gasifiers.

Objective To detect the expression of apoptotic inhibitor protein Livin in different esophageal epithelial lesions and to analyze the relation between the expression of Livin with pathologic characteristics. Methods The expressions of Livin mRNA and Livin protein were detected by real- time fluorescence quantitative PCR and western blot in 40 patients with different esophageal epithelial lesions including normal, atypical hyperplasia, carcino-ma in stiu and invasive carcinoma. Results The expressions of Livin mRNA were progressively increased from nor-mal to invasive carcinoma( 1.00 ± 0. 00,2.26 ± 0.79,7.24 ± 1.06,12.21 ± 2.47 ). There was statistical signifi-cance in Livin mRNA expression among carcinoma in stiu and invasive carcinoma and normal tissues ( P < 0.05 ). Conclusion The expression of Livin is significantly related to the progression of esophageal cancer,which may be a new target for diagnosis and gene treatment of esophageal carcinoma.

AIM:To investigate the combination therapeutic effect of ulinastatin and berberine on burn sepsis in the rats.METHODS:The rats with burn sepsis were administrated with ulinastatin or berberine or combination therapy .The survival rate and body weight of the rats were measured .The levels of IL-6, IL-10 and TNF-αwere examined by ELISA.The morphological changes of the lung were observed by hematoxylin and eosin staining .The content of bacteria in the liver , lung and spleen tissues was detected .RESULTS:Combination of ulinastatin and berberine significantly increased the survival rate and body weight in the rats with burn sepsis .Moreover , combination therapy inhibited the elevation of IL-6 and TNF-αlev-els, whereas increased the IL-10 level.Combination therapy protected the structure of hepatic lobule , and further reduced the bacterial content in the liver , lung and spleen .CONCLUSION: Combination of ulinastatin and berberine improves the symptoms of burn sepsis by regulating the levels of IL-6, IL-10 and TNF-αand inhibiting the content of bacteria .

Objective To investigate the morphological regularity of the thoracic pedicle screw in 4 to 12 years old children by the digital technology,and to provide the theoreticl basis for thoracic pedicle screw fixation in children.Methods A total of 60 healthy children aged from 4 to 12 years old with computed tomography(CT) data of thoracic spine were divided into three groups by age,each group 20 cases.Then they were examined by MIMICS software and the parameters of pedicle width(PW),pedicle height(PH),the length of screw path(SL),e angle and f angle were measured.Results The pedicle width,pedicle height,the SL of the pedicle generally showed a rising trend with advancing age.There were significant differences in the PW,PH and LS between the three group(P<0.05).The PW decreased and then increased.The PH and the LS increased with the vertebral order increased.There was no significant difference in e angle and f angle between the three groups(P>0.05).E angle of the pedicle generally showed a decreasing trend with increasing vertebral order,and e angle of T11 to T12 showed negative angle.The f angle showed a wavy descending trend.Conclusion There was significant difference in correlation parameters of thoracic pedicle with increasing age in healthy children,which indicates that the pedicle screw fixation for the kind of children should be performed based on 'the Principle of individualization' to improve the success rate of surgery.

Objective This study aims to evaluate the initial results of a hybrid procedure for treating descending thoracic aortic disease that involves distal aortic arch.It also intends to report our initial experience in performing this procedure.Methods A total of 45 patients(35 males and 10 females) with descending thoracic aortic disease underwent a hybrid procedure,namely,thoracic endovascular aortic repair(TEVAR) combined with supra-arch branch vessel bypass,in our center from April 2009 to August 2014.Right axillary artery to left axillary artery bypass(n =20) or right axillary artery to left common carotid artery and left axillary artery bypass(n =25) were performed.The conditions of all patients were followed up from the 14th month to the 77th month postoperative[mean(38.0 ± 17.1) months].Mortality within 30 days,complications such as endoleak after the hybrid procedure,and stenosis or blockage of the bypass graft during the follow-up period were assessed.Results One case of death and one case of cerebral infarction were reported within 30 days.Two patients underwent open surgery beacuse of endoleak.And a newly formed intimal tear was observed in one patient and the patient underwent a second TEVAR during the follow-up period.Condusion Initial results suggest that the one-stage hybrid procedure is a suitable therapeutic option for thoracic aortic pathologies that involve distal aortic arch.However,this procedure is not recommended for type-B aortic dissection,in which a tear is located in the greater curvature or near the left subclavian artery,because of the high possibility of endoleak occurrence.

Fifty-four children, aged 1.5-3.5 years, were selected from a nursery and divided into three groups. To the children in group 1 multivitamin fortified formular milk powder of Hai-He brand (70g daily) was given as a supplementary food in addition to the normal diet and whole milk powder of Hai-He brand was given to group 2 as another supplementary food. The third group served as control. This observation was lasted for three months. At the end of the third month, the increments of body weight of the children, tricep skinfold and circumference of upper arm of group 1 were higher than those of group 3 significantly, but there were no significant differences between group 1 and group 2. The hemoglobin content of group 1 increased by 0.8g/dl but group 2 and 3 decreased by 0.53g/dl and 0.72g/dl respectively. At the end of our observation, the concentrations of vitamin B1, C and PP in urine of group 1 were higher than those of other two groups by vitamin load test.Thus, we may consider that the multivitamin fortified milk powder is better than the whole milk powder in improving the vitamin and iron nutritional status of young children.
