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 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.

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 effect of Emodin on intracellular calcium concentration ([Ca~(2+)]i) and apoptosis of hepatic cells after simulated cold ischemia-reperfusion. Methods Glucose-oxygen deprivation, low temperature, subsequent reoxygenation and rewarming were used to induce ischemia-reperfusion injury model in cultured hepatic cells which were divided into 4 groups: control group and Emodin-treated group(100, 10 and apoptosis rate were determined by flow cytometry (FCM) respectively; the content of lactate dehydrogenase (LDH) in supernatant was tested. Results Intracellular calcium fluorescence intensity in Emodin-treated groups of high, medium and low density was 24.12±0.51, 26.35±1.34 and 39.12±1.94, respectively, which were significantly lower than 105.29±1.01 in control group(P<0.01). Apoptosis rate in Emodin-treated groups of high, (179.67±18.57)u/L in Emodin-treated groups of medium and high density respectively, which were significantly lower than (351.33±34.16)u/L in control group(P<0.01). Conclusion Emodin could reduce [Ca~(2+)]i and inhibit apoptosis of hepatic cells after simulated cold ischemia-reperfusion, thus protecting hepatic cells effectively.

Objective To establish a model of rat orthotopic liver transplantation and investigate the relationship among cold preservation time, activation of nuclear transcription factor-κB (NF-κB) and donor preservation injury after liver transplantation. Methods Orthotopic liver transplantation was performed in Wistar rats which were randomly divided into the following groups according to the different duration of liver cold storage in UW solution: group A (sham operation, n=10), group B NF-κB in liver before and after transplantation was measured by electrophoretic mobility shift assays; protein expression of tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) in the liver was measured by immunohistochemistry; the serum TNFα and IL-1β, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and hepatic cell apoptosis were examined. Results With extended cold storage duration, the activity of NF-κB in the donor liver increased (P<0.05, group D vs. groups A, B and C). TNF-α and IL-1β levels also increased (P<0.05, group D vs. groups A, B and C). Donor liver reperfusion injury was gradually aggravated with the prolonging of graft cold preservation. Both the serum TNF-α and IL-1β levels increased highly (P<0.05 group A vs. groups B, C and D),NF-κB in the liver significantly increased (P<0.05, group A vs. groups D, B and C) with gradual prolonging of graft cold preservation time. The serum ALT and AST level and apoptosis index level elevated greatly (P<0.05, group A vs. groups D, B and C). Conclusion NF-κB of donor liver was activated inductively in cold preservation phase and activated explosively in reperfusion phase. The longer cold preservation time was, the higher NF-κB level in donor liver became. NF-κB led to the expression of TNF-α and IL-1β in donor liver. Inflammatory factors are one of the most important mechanisms for the donor liver injury after liver transplantation.

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.
