Objective:To analyze risk factors that were associated with loss of correction curvature after short-segment restoration and fixation in cases who had single-segment thoracolumbar fracture.Methods:87 Cases who had experienced single-segment thoracolumbar fracture and had underwent short-segment restoration and fixation in our department from Jan 2008 to Jan 2011,and had complete follow-up imaging were included.Cobb angles were measured on lateral thoracolumbar X-ray preoperatively,postoperatively and before removal of internal fixation.And these included the angle formed by vertebras that located above and below injured vertebrae (α angle),superior endplate of injured vertebrae and its superior vertebrae (β angle),inferior endplate of injured vertebrae and its inferior vertebrae (γ angle),inferior and superior endplate of injured vertebrae (δ angle).T-test was used to analyze these angles and their changes.And correlation analysis was used to analyze relationships between α angle change and other risk factors.Results:When compared with preoperative angles,the mean α angle,β angle,γ angle and δ angle were all significantly increased (p＜0.05) after the operation.The mean α angle and δ angle before the removal of internal fixation were both significantly smaller than those after the operation (p＜0.05),and the mean change ofα angle was-2.85 degrees.After the correlation analysis,we found significant correlations between the change ofα angle and postoperative correction curvature(-0.342,p=0.026),injured region in endplate(0.374,p=0.015),and change of the δ angle(0.231,p=0.041).Conclusion:There was significant loss in the correction curvature before the removal of internal fixation.And the loss was significantly associated with postoperative correction curvature,injured region in endplate,and change of the δ angle.

Neuroblastoma(NB),the common extracranial solid tumor of childhood,is thought to derive from neural crest cells.In disialoganglioside (GD)2 is highly expressed on NB,whereas GD2 expression is weak and restricted to the central nervous system,peripheral pain fibers and skin melanocytes.Therefore,GD2 is an ideal antigen target for immunotherapy of NB.The research progress on GD2 as target for immunotherapy of NB was reviewed.

Objective To evaluate the role of autophagy on acute kidney injury after liver transplantation.Method Fifty-six healthy male Sprague-Dawley rats were randomly assigned into 4 groups:sham group,orthotopic liver transplantation (OLT) group,sirolimus pretreated (SRL) group and 3-methyladenine pretreated(3-MA) group.OLT model was established.Then the rats were sacrificed at 6 h after reperfusion.The renal function and the extent of oxidative stress relative proteins malondialdehyde (MDA) and superoxide dismutase (SOD) were observed.The levels of apoptosis relative genes caspase-3 and cyt c and the expression of autophagy relative proteins were detected.The pathological changes were microscopically examined in renal tissues.TUNEL staining was used to observe the apoptosis of tubular epithelial cells.Transmission electron microscopy was applied to observe the ultrastructure changes of tubular epithelial cells.Result As compared with sham group,OLT and 3-MA groups showed a serious renal injury including cellular vacuolization,loss of brush borders,and a significant rise in BUN,Cr and MDA,while a decrease in SOD activity.The levels of caspase-3 mRNA and cyt c rnRNA were increased significantly.Whereas compared to OLT and 3-MA groups,renal function and oxidative stress levels in SRL group ameliorated,and histopathologic damage and apoptosis alleviated after OLT.Simultaneously,the levels of caspase-3 mRNA and cyt c mRNA were decreased.The expression of beclin-1 and LC3-]Ⅱ was effectively upregulated.Conclusion Autophagy could alleviate acute kidney injury after liver transplantation through inhibiting oxidative stress and apoptosis.

Objective: To establish microbiological method for determining biotin in foods and feeds. Methods: Using biotin dependent microorganisms Lactobacillus plantarum(ATCC 8014), the biotin content was detected indirectly by the growth of cultrued bacteria spectrophotometrically.Results: The detection limit was 0.03 ng. The relative standard deviations(RSD) of within and between run assays were 2.2%-3.8%,2.1%-5.3% respectively. The recovery of added biotin was 93.4%-104.6%, and RSD was 3.1%-4.1%. Conclusion: This assay is sufficiently accurate and repoducible for determining biotin in foods and feeds.

Objeetive To investigate the risk of hemorrhagic transformation (HT) and the outcome as well as its influencing factors at 3 months after thrombolytic therapy in acute ischemic stroke patients with non-valvular atrial fibrillation (NVAF).Methods Consecutive acute ischemic stroke patients with NVAF were enrolled retrospectively.Their demography,vascular risk factors and other clinical data were collected.The modified Rankin Scale (mRS) was used to evaluate the outcome at 3 months after symptom onset.The mRS score ≤ 2 was defined as good outcome,and ＞ 2 was defined as poor outcome.Results A total of 119 acute ischemic stroke patients with NVAF were enrolled,including 63 males (52.9％) and 56 females (47.1％); their mean age was 72.1± 10.0; 45 (37.81％) were treated with recombinant tissue type plasminogen activator (rtPA),55 (46.2％) had a good outcome and 27 (22.7％) combined with HT.Compared with the poor outcome group,the mean age was younger in the good outcome group (P =0.028).The proportions of the patients with ischemic heart disease and the time from onset to treatment ＞ 4.5 h were lower (P ＜0.05).The baseline systolic blood pressure and diastolic blood pressure,as well as the National Institutes of Health Stroke Scale (NIHSS) score were lower (P ＜0.05),while the proportion of patients receiving intravenous thrombolysis with rtPA was higher (P =0.019).Multivariate logistic regression analysis showed that the patients with ischemic heart disease (odds ratio [OR] 4.572,95％ confidence interval [CI] 1.392-15.014; P =0.012),systolic blood pressure before treatment (OR 1.028,95％ CI 1.007-1.049; P =0.009),baseline NIHSS score (OR 1.058,95％ CI 1.002-1.117; P =0.042) were the independent risk factors for poor outcome,while intravenous thrombolysis with rtPA (CI 0.264,95％ CI 0.102-0.683; P =0.006) was an independent protective factor for poor outcome.The proportions of the baseline systolic blood pressure,fasting blood glucose and NIHSS score,as well as the patients with a history of previous stroke or transient ischemic attack (TIA) in the HT group were significantly higher than those in the non-HT group (all P ＜ 0.05).Multivariate logistic regression analysis showed that the baseline NIHSS score (OR 1.147,95％ CI 1.068-1.231; P＜0.001),baseline systolic blood pressure (OR 1.951,95％ CI 1.921-1.982; P =0.002),and blood glucose level (OR 1.191,95％ CI 1.095-1.294; P ＜ 0.001) were the independent risk factors for HT.Compared with the non-thrombolysis group,the mean age of the thrombolysis group was younger (P =0.021),the baseline systolic blood pressure,fasting glucose and NIHSS scores,as well as the proportions of patients with hyperlipidemia,previous stroke or TIA history,and using antihypertensive drugs before admission were higher (all P ＜ 0.05).The proportion of patients with ischemic heart disease were lower (P =0.035),but the proportion of the patients with a good outcome was higher (P =0.019).Conclusions Patients with ischemic heart disease,systolic blood pressure and higher baseline NIHSS score before treatment were the independent risk factors for poor outcome,while intravenous thrombolytic therapy with rtPA was an independent protective factor for poor outcome; the high baseline NIHSS score,baseline systolic blood pressure and glucose level were the independent risk factors for HT.For acute ischemic stroke patients with NVAF,such as no obvious contraindications for thrombolytic therapy,might benefit from intravenous thrombolytic therapy,and it could not increase the risk of HT,but the blood pressure and glucose level of the patients should be controlled appropriately.

Objective To analyze quantitatively the histological components, and to observe the morphological changes of the transition zone in benign hyperplastic prostates (BPH) and adult normal prostates. Methods The quantitative morphometry of 40 BPH specimens obtained from suprapubic transvesical prostatectomy and 10 normal prostatic specimens (controls) were performed with computer-assisted image analysis system,and all the samples were stained with hematoxylin and eosin (HE) and the Masson trichrome.The area percentages of stromal (smooth muscle and connective tissue),glandular epithelial and luminal components,the average areas of acini,lumens and epithelia,and the heights of epithelial cells were quantitated,respectively. Results ①The mean area percentages of different components between control group and BPH group were as follows: smooth muscles,(23.83?8.53)% vs (35.35?8.33)% ( P 0.05);epithelia,(26.26? 7.45)% vs (17.76?4.61)% (P0.05).②The average areas of acini, epithelia and lumens of control group and BPH group were ( 0.087?0.028)mm 2 vs (0.062?0.030)mm 2 (P

0.05)). The Val/Leu genotype and Leu allele frequencies in subjects without MI were significantly higher than that in subjects with MI (P

Objective To explore the reliability and validity of the Chinese version of the 36-item Short Form Health Survey (SF-36) for evaluating the health-related quality of life of patients with chronic soft tissue pain, (CSTP). Methods Two hundred and ten CSTP patients were rated with the SF-36 and the Medical Outcomes Study Pain Measurement (MOSPM) instrument and retested 2 weeks later. The internal consistency, test-retest relia-bility and parallel validity of the SF-36 were analyzed. Results The SF-36 showed good internal consistency and test-retest reliability. Most repeated reliability internal correlation coefficients were between 0.44 and O. 66 (P≤0.01) except that of the SF sub-scale of the SF-36, which was O. 336 (P≤0.05). All the internal consistency Cronbach's a coefficients were >0.70. In the assessment of validity, there was significant correlation among all eight sub-scales of the SF-36, and between items 4-11 and total MOSPM scores. The correlation coefficients were between -0.145 and 0. 635 (P≤0.05 or P≤0.01), except between GH of the SF-36 and item 4 of the M OSPM (pain in-fluence on walking) and between MH and item 10 (pain influence days). Conclusion The Chinese version of the SF-36 has good reliability and validity in assessing the health related quality of life of CSTP patients.
