This paper reports the nursing care of 12 patients with idiopathic scoliosis treated with halo-pelvic traction preoperatively which focused on breathing training, traction frame management. One patient suffered from temporary brachial plexus injury and four cases suffered from superior mesenteric artery syndrome. With 14-21 day's traction and nursing care, the correction rate of Cobb angle was 35%-50%,the forced vital capacity was improved by 25%,and all the patients received orthomorphia surgery in time. It is suggested that the patients with severe idiopathic scoliosis treated by halo-pelvic traction could take out-of-bed activity freely. It could not only relieve pain and reduce mental pressure, but also improve the safety of orthomorphia surgery.

Objective To investigate the therapeutic effect of tumor necrosis factor (TNF)-αsiRNA on typeⅡcolla-gen induced arthritis (CIA) in rats. Methods The expression vectors of siRNA against TNF-αgene were constructed suc-cessfully and were injected by tail veil into CIA rats. Twenty-four CIA rats were randomly divided into 4 groups including model group, empty vector group, TNF-α-siRNA1 group and TNF-α-siRNA2 group. CIA rats were injected with the same dose of phosphate buffered sodium (PBS) and pGFP-V-RS vector respectively in model group and empty vector group, while TNF-α-siRNA1 group and TNF-α-siRNA2 group were injected with TNF-α-siRNA1 eukaryotic expression vector and TNF-α-siRNA2 eukaryotic expression vector respectively. Another 6 rats, which were not established CIA model, were in-jected with PBS (blank control group). The serum expression levels of IL-1 were detected by ELISA on day 1, 5, 9 and 13 af-ter injection. The expression level of TNF-αmRNA was detected by reverse transcriptase polymerase chain reaction (RT-PCR) on day 13. Results The expression level of IL-1 was significantly higher on day 1, 5, 9 and 13 in model group than that of blank group (P<0.05). The expression levels of IL-1 were significantly lower on day 1, 5 and 9 in TNF-α-siRNA1 group and TNF-α-siRNA2 group than that of model group and blank group (P < 0.05). The expression level of TNF-αmRNA was significantly higher on day 13 in model group than that of blank group (P<0.05). The expression levels of TNF-αmRNA were significantly lower in TNF-α-siRNA1 group and TNF-α-siRNA2 group than those of model group and emp-ty vector group (P<0.05). Conclusion TNF-αspecific siRNA can suppress the levels of TNF-αmRNA and IL-1, which provides experimental basis for gene therapy of rheumatoid arthritis.

Objective To explore the roles of interleukin-6 (IL-6) and high sensitive C-reactive protein (hsCRP) in coronary heart disease (CHD). Methods One hundred and fifty patients diagnosed as angina pectoris by coronary angiography were enrolled and randomly divided into unstable angina pectoris group ( UAP group n =78) and stable angina group (SAP group n =72). At the same time,50 cases with normal coronary angiography were selected as control. The plasma level of IL-6 was measured by ELISA, and hsCRP was measured by immunonephelometry. Results The mean plasma levels of IL-6 and hsCRP were significantly higher in UAP group compared with SAP group ( IL-6 ( 36. 98 ± 9. 35 ) pg/L vs. ( 23.19 ± 7. 35 ) pg/L; hsCRP ( 2. 25 ± 0. 73 ) μg/Lvs 1.88 ± 0. 68 ) μg/L; P < 0. 01 respectively), both were significantly higher than those of control group ( IL-6 (16. 93 ± 6. 15 )pg/L and hsCRP (1.28 ± 0.40)μg/L,P <0.01 respectively). We also found significantly positive relationship between IL-6 and hsCRP plasma level ( r = 0. 875, P < 0. 05 ). Conclusions Inflammatory response might play an important role in CHD. IL-6 and hsCRP were of high value in prediction of angina pectoris and development of CHD.

Objective To explore the incidence and risk factors of bacterial infection after othtotopic liver transplantation (OLT). Methods Altogether 56 OLT recipients from January 2005 to October 2007 were included in the study. The incidents and the related variables of the infection were analyzed retrospectively. The related variables were evaluated using multivariate logistic regression model to identify the significant risk factors. Results Bacterial infection was confirmed in 29 recipients (51.8%). Among them, the lung infection was the most common site (53.7%). The Gram-positive cocci were 46.3%, while the Gram-negative bacilli were 53.7%. The risk factors for bacterial infection included duration of the operation and detained respirator using. Conclusion Bacterial infection is a major complication following OLT. Surveillance for the risk factors, enhancement the skill of operation, and improving the recovery of respiratory function is the key to decreasing the incidence of bacterial infection after transplantation.

Objective To explore the clinical value of intra-arterial thrombolytic therapy for hepatic artery thrombosis after liver transplantation. Methods Routine color doppler imaging (CDI) was used to detect hepatic artery thrombosis (HAT) after liver transplantation in 160 cases. Suspected patients were further confirmed by immediate angiography. Four cases of HAT were diagnosed and treated by intra-arterial thrombolysis. Two cases received repeatable transcatheter hepatic arterial thrombolysis with a low dose of urokinase. Results Hepatic artery recanalization was achieved in 3 cases. Among the 3 cases, multiple HAT occurred in 1 case, intra-arterial thrombolysis was successfully completed in the end. Two cases had intra-abdominal hemorrhage, which was cured by conservative treatment. One case received retransplantation because of interventional thrombolysis failure and intra-abdominal hemorrhage. Conclusion Intra-arterial thrombolytic therapy may be a promising method in the treatment of HAT. Transcatheter hepatic arterial thrombolysis shows a significant result.

OBJECTIVETo evaluate the effect of static magnetic field on the expression of SP-mRNA in TG in rats.
METHODS44 Wistar rats aged 6-7 weeks were put into static magnetic field and were sacrificed at 1 h, 2 h, 6 h, 12 h, 24 h, respectively. In situ hybridization method was used to evaluate the changes of SP-mRNA expression at different time point.
RESULTSMany neurons in TG were marked with SP probes in each group, the expression of SP-mRNA increased remarkably in static magnetic field group. In this group, the percentage of SP-mRNA positive neurons in TG increased greatly in 1 h, reached its peak in 2 h, from then on, decrease of the percentage started slowly but a moderate percentage was kept until 24 h, which was thought to be enough to maintain orthodontic tooth movement. The tendency of control group was almost the same with that of experimental group. The expression of SP-mRNA was higher in experimental group within 2 h but became lower after 2 h as compared with control group, this indicated that magnetic field reduced the SP-mRNA expression and exerted restoring effect on trauma. There were significant differences between experimental groups and control group at different time points (P < 0.01).
CONCLUSIONThe expression of SP-mRNA in TG in rats increased significantly in static magnetic field.
