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.

A retrospective analysis was conducted for male Han patients aged 46 years or above undergoing serum test of total prostate specific antigen (tPSA) at our hospital from 2007 to 2009.Among them,there were 109 patients with complete clinical data (including a history of hypertension and dyslipidemia),including 36 type 2 diabetics and 73 non-diabetics.For type 2 diabetes and non-diabetes groups,the median values (lower quartile,upper quartile) of serum tPSA test results were 1.01 (0.44,3.43) μg/L and 2.26 (1.04,5.48) μg/L (t =-2.65,P ＜0.01) respectively.The serum level of tPSA in type 2 diabetics was significantly lower than that in non-diabetics.

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 establish a novel method for the determination of betaine in serum by high performance liquid chromatography with UV detection.Methods Pre-column derivatization of serum was performed directly in acetonitrile without extraction with p-bromophenacyl bromide and 18-crown-6 ether as catalyst.The p-bromophenacyl ester derivatives were then separated by Supelcosil LC-SCX, using an was 0.8 ml/min and the effluent was monitored at 259 nm. Betaine was used for preparation of standard curve and quantification with external standards.Results The linearity of this method was 6.25-200.00 μmol/L,the regression was 0.999 8.The detection limit was 3.0 μmol/L.The within-day imprecision was 1.88%-3.79% ( average 3.24% ), the between-day imprecision was 3.14%-6.76% ( average 4.39% ), the recovery rates were 95.89%-102.86% (average 99.16% ).Conclusion This method is sensitive, rapid, accurate and suitable for the research and routine clinical practice.

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.

Objective: our study was to investigate the effect of hepaCAM gene on cell cycle of bladder cancer cell line T24 and BIU-87. Method: Adenovirus vector with hepaCAM was infected into T24 and BIU-87 cells. The expression of hepaCAM mRNA and protein were measured byRT-QPCR and Western-blot. Immunofluorescence detected the cellular localization of hepaCAM. The distribution of cell cycle was analyzed by FCM. The protein expression of cyclinD1 was measured by Westein-blot. Result: The expression of hepaCAM mRNA and protein was increased in two cell lines infected with pAdH5-hepaCAM. The G0/G1 cycle was increased in infected cells, and the protein expression of cyclinD1 was decreased in same cells. Immunofluorescence revealed that hepaCAM protein localized on cytoplasm in well-spread cells, otherwise it localized on the junction of each cell. Conclusion: T24 and BIU-87 cells that infected pAdH5- hepaCAM was blocked in G0/G1 cycle, and it can decreased the protein expression of cyclinD1.

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.

Objective To investigate the efficacy of concomitant precise hemihepateetomy for the treatment of hilar cholangiocarcinoma.Methods The clinical data of 38 patients with hilar cholangiocarcinoma who received concomitant precise hemihepatectomy at the First Affiliated Hospital of Xi'an Jiaotong University from January 2009 to October 2012 were retrospectively analyzed.All patients were examined by B ultrasonography,computed tomography (CT),magnetic resonance cholangiopancreatography (MRCP) and CT angiography (CTA)preoperatively.The hepatic function was tested before operation.Of the 7 patients with obstructive jaundice,5 received percutaneous transhepatic cholangial drainage,and 2 received endoscopic nosalbiliary drainage.Surgical procedures were determined according to the results of imaging examination.The resection of hilar cholangiocarcinoma,postoperative histopathological examination,pre-and postoperative hepatic function and prognostic indicators were analyzed.The count data and measurement data were analyzed using the chi-square test and t test,respectively; the survival curve was drawn by Kaplan-Meier method,and the survival rate was analyzed using the Log-rank test.COX proportion hazards model was used for multivariate analysis.Results The positive rates of B ultrasonography,CT and MRCP were 65.8％ (25/38),71.1％ (27/38) and 89.5％ (34/38),respectively.The results of 5 patients who received CTA were positive.Concomitant left hemihepatectomy was performed on 28 patients,concomitant right hemihepatectomy on 10 patients; concomitant caudate lobectomy on 22 patients,concomitant resection and reconstruction of portal vein on 4 patients (including 1 patient who received left hepatic vein repair),concomitant hepatic artery resection on 12 patients (including 3 patients who received hepatic artery reconstruction).Of the 38 patients,R0 resection was performed on 32 patients,R1 resection on 4 patients,R2 resection on 2 patients.Hepatic function indicators including total bilirubin,direct bilirubin,alkaline phosphatase,gamma-glutamyl-transferase,alanine aminotransferase and aspartate aminotransferase were significantly decreased after operation (t =7.799,8.445,5.697,6.633,4.469,4.140,P ＜ 0.05).Two patients died perioperatively,with the mortality rate of 5.3％ (2/38).The main postoperative complications included bile leakage and hepatic function insufficiency,with the incidences of 28.9％ (11/38) and 21.1％ (8/38),respectively.Postoperative histopathological findings included 31 patients with invasive adenocarcinoma,5 patients with nodular adenocarcinoma,1 patient with mucinous adenocarcinoma and 1 patient with adenosquamous carcinoma.The overall 1-,2-,3-year survival rates were 66％,37％ and 21％,and the median survival time was 22.0 months.There were significant differences in the survival rates between patients who received R0 resection and those with R1/R2 resection,and between patients with N0 and N1/N2 stage (x2 =4.516,10.397,P ＜ 0.05).The results of multivariate analysis showed that positive margin and lymph node metastasis were prognostic indicators.Conclusions Concomitant precise hemihepatectomy has significantly improved the radical resection rate and the efficacy of treatment for hilar cholangiocarcinoma.Comprehensive preoperative imaging examination and hepatic function test are important for the assessment for resectability of hilar cholangiocarcinoma.Selective preoperative biliary drainage are key points to decrease postoperative morbidity and morality.
