SW872 preadipocytes were cultured and induced to differentiate by oleic acid in vitro.The levels of adiponectin and its receptors (AdipoR1 and AdipoR2) mRNA were measured by semiquantitative RT- PCR.The concentration of adiponectin in the culture medium was assayed by ELISA.The results showed that rhIL- 6 could inhibit adiponectin,AdipoR1 mRNA expressions and adiponectin secretion in SW872 adipocytes in a time- and dose-dependent manner,but did not influence adipoR2 mRNA expression.

Objective To discuss the common causes for postoperative complications after treatment of spinal fractures and their preventive measures.Methods To analyze the 32 failed eases who received internal fixation for their thoracolumbar fractures between July 1998 and April 2005 in our department.Their preoperative and postoperative results of X-ray,CT and MIR examinations were reviewed to find out the causes for failure.Three of them were treated through anterior approach and 29 through posterior approach.Eighteen screws broke in eight eases, the rods got loosened in eight cases and broken in four cases,15 pedicte screws were mis-located in eight cases and the implants got loosened in three cases.Results Thirty patients had to get a reoperation.Two were cured through non-surgical treatment.The causes for failure were found to be as follows:1,incorrect operation approach;2,in- stability of the front-middle colunm;3,unskillful operation;4,ignorance or the lesion to the adjacent vertebral discs; 5,flaws in pedicle screw design.Conclusion To prevent postoperative complications after internal fixation for spinal fractures,surgeons should strictly stick to the indications before operation,choose a proper approach and method for internal fixation,try to stabilize the front-middle column by the first intention,and have a good command of anatomy and operation skills.

Stenotrophomonas maltophilia is among eight strain of broad resistance to antibacterial. It has been pay attention to global students, and is very difficulty in clinic treatment. Infection of Stenotrophomonas maltophilia is more familiar in ICU. Its test rate is 13.45%(62/461) in the study .The resistance character: IPM﹑CZO﹑CRO﹑AMP and MNO is highest(resistive rate 100%). ATM、GEN 、 KAN 、MEM 、CTX and PIP is much high(≧86.5%), LVX﹑GAT and FEP is high (=50%).Conclusion: Stenotrophomonas maltophilia should be monitored in the hospital. Used of antibacterial must be rational. Severe disinfection and isolation should been put in practice to the infected patients. CSL is very active antibacterial (active rate 90.6%) against Stenotrophomonas maltophilia in the study, and ought be selected headmost in treated its infection.

The process mechanism and current application status of boron removal in reverse osmosis(RO)desalination were introduced.The characteristic and proper application range of eachboron removal process was summarized.Also,the running conditions of two practical desalination cases were analyzed and compared.Eventually,the future of application and the research direction of boron removal process in RO desalination were prospected.

OBJECTIVE: To analyse the risk factors involved in local failure following radiotherapy and chemotherapy to nasopharyngeal carcinoma. METHOD: A retrospective analysis was carried out to review the histopathological data from 308 NPC patients who recieved medical treatment between 2004 and 2006. The incidence and the risk factor for local treatment failure were evaluated in a model that included the following factors: sex, age, T and N staging, histological grade of primary tumor, presence of cervical lymph node metastasis, size and laterals of positive neck nodes, levels involved, ways of radiation and condition of concurrent chemotherapy. Univariate chi2 test and multivariate stepwise logistic regression model were used for the analysis. Statistical analysis of survival of patients with local residues and recurrence was performed using Kaplan-Meier method. RESULT: Ninty-three cases (30.2%) presented local residues and recurrence in 308 patients of nasopharyngeal carcinomas. In the univariate analysis, it was confirmed that the following variables correlated to local failure, i. e., T staging (P < 0.01), N staging (P < 0.01), presence of cervical lymph node metastasis (P < 0.05), size and laterals of positive neck nodes (P < 0.05, respectively). In the multivariate analysis, the most ignificant risk factors for local failure were the T staging only. Kaplan-Meier analysis showed that overall survival rates of 71 NPC patients with local residues and recurrence who received re-treatment were 77.2% at 1 year, 40.4% at 3 years, 22.4% at 5 years, respectively. CONCLUSION T staging is the key risk factors in determining the development of local failure following radiotherapy or chemotherapy in NPC patients. Patients with primary tumor infiltrating bone have the higher risk of developing local residues and recurrence. Retreatment to the patients suffering from local failure can imrove survival rates.
