Objective To explore the feasibility and safety of Mckeown-type minimally invasive esophagectomy in para-recurrent laryngeal nerve lymphadenectomy. Methods A total of 163 cases underwent minimally invasive McKeown resection for esophageal carcinoma in the Affiliated Tumor Hospital of Xinjiang Medical University were retrospectively analyzed. Patients were divided into routine treatment group (n=63), right recurrent nerve lymph node dissection group (right group, n=53) and bilateral recurrent laryngeal nerve lymph node dissection group (bilateral group, n=47) according to the operation modes. The postoperative pathology, operation time, intraoperative bleeding volume, postoperative hospitalization time, number of lymph nodes and pneumonia, anastomotic fistula, laryngeal nerve injury and other complications were compared between three groups of patients. Pathological conditions were consisted of the location of tumor, the degree of differentiation, T stage and pathological stage. Postoperative complications were followed up for 6 months. Results There were no significant differences in tumor location, pathological differentiation degree, T stage and pathologic stage between three groups. The amount of bleeding was more in the routine group than that of the right group and the bilateral group (P<0.05). There was no significant difference in the amount of bleeding between the right group and the bilateral group. The total lymph nodes and thoracic lymph nodes were increased in order in routine group, the right group and the bilateral group, and there was significant difference between three groups(P<0.05). There were no significant differences in other operation data and complications between three groups. Conclusion McKeown-type minimally invasive esophagectomy shows good feasibility and safety for para-recurrent laryngeal nerve lymphadenectomy .

Aim To determine the function of nuclear factor-κB ( NF-κB ) in immunological liver injury of rat model and its effect on CYP2E1 expression, content and metabolic activity. Methods The immunological liver injury rat model was prepared by injection of Ba-cillus Calmette Guérin ( BCG,125 mg · kg-1 ) for 14 days. The hepatic tissue injury was revealed by hema-toxylin and eosin ( HE ) method and serum concentra-tion of alanine aminotransferase( ALT) , aspartate ami-notransferase ( AST ) respectively. CYP450 total con-tent in hepatic homogenate was determined by spectro-photography. The expression of CYP2E1 protein was detected by Western blot analysis. The enzyme kinetics of CYP2 E1 probe drug chlorzoxazone was evaluated by high-performance liquid chromatography ( HPLC ) as-say. Results The results showed that BCG-pretreat-ment ( 125 mg · kg-1 ) significantly increased the weight of liver and spleen, serum levels of ALT and AST(P<0. 01) , and decreased CYP2E1 expression, content and metabolic activity ( P <0. 05 ) . Adminis-tration of ammonium pyrrolidine dithiocarbamate (PDTC) (50, 100, 200 mg·kg-1) reversed the a-bove hepatic injury stimulated by BCG in vivo. Moreo-ver, PDTC dose-dependently inhibited the down regu-lation of CYP2 E1 ( P<0. 05 ) . Conclusion Passiva-tion of NF-κB can inhibit the down regulation of CYP2 E1 in liver tissue of immunological liver injury rats;NF-κB may be involved in CYP2 E1 down-regula-tion.

Objective To investigate whether IL-17 could stimulate the vascular endothelial growth factor (VEGF) production on HaCaT cells alone. We also investigated whether shikonin could inhibited the proinflamation effects of interleukin-17(IL-17) acting on HaCaT cells. MethodsWe examined the expression of VEGF by double antibody sandwich enzyme-linked immunosorbent assay ( ELISA ) and realtime polymerase chain reaction(RT-PCR) in HaCaT cells and the cell supernatant. The viability of HaCaT cells in the drug group was detected by the Cell Counting Kit-8 (CCK-8). ResultsThe expression of VEGF in different time IL-17-stimulated groups on HaCaT cells and the cell supernatant were higher than the control group( P<0.001 ). The expression of VEGF in different drug treatment groups on HaCaT cells and the cell supematant were lower than the stimulated group by IL-17 ( P<0. 001 ). The cell viability of different drug treatment groups have no significant difference( P>0.05 ). ConclusionWe show that IL-17 specifically and time-dependently augmented and induced VEGF expression on HaCaT cells and the cell supernatantThen shikonin markedly inhibited the increase tengency of IL-17 effection on HaCaT cells and the cell supematant level.

Objective To treat radial head fractures with open reduction and internal fixation, removal of the radial head and artificial joint replacement based on different fracture types to discuss the outcome of these methods and summarize optimal strategy for treatment of radial head fractures. Meth-ods A retrospective study was done on data of 47 patients with 48 radial head fractures treated in our de-partment from November 1999 to May 2008. Among them, nine patients were treated conservatively (all type Mason Ⅰ fractures), 28 treated with open reduction and internal fixation (one patient with type Ma-son Ⅰ fracture, 14 with type Mason Ⅱ and 13 with type Mason Ⅲ), eight with removal of radial head (three patients with type Mason Ⅲ fractures and five with type Ⅳ) and three with artificial joint replace-ment (all type Mason Ⅳ fractures). Results All patients were followed up for average 2.8 years (1-4.4 years). Two patients treated with artificial joint replacement were followed up for six months and three months respectively. According to the Mayo Elbow Performance Index, the excellence rate was 8/9 in conservative treatment, 82% (23/28) in open reduction and internal fixation, 6/8 in removal of the radial head and 3/3 in artificial joint replacement respectively. Conclusions The radial head fracture should be given anatomical reduction for early functional exercise. Conservative treatment can be used for type Mason Ⅰ fractures, open reduction and internal fixation for type Mason Ⅱ , type Mason Ⅲ fractures and part of type Mason Ⅳ fractures. The removal of radial head or mental prosthesis replacement are al-ternative for parte of type Mason Ⅳ fractures that can not attain stable fixation through open reduction and internal fixation.
