Objective To investigate the effect of early intervention on adhesion molecule NB-3 expressing in cerebral injured neonatal rat induced with intrauterine infection. Methods Pregnant rats were consecutively injected with lipopolysaccharide (LPS) 380 μg/kg or saline 17 d after gestation. The offspring from the LPS group accepted early intervention (I group, n=40) or not (NI group, n=40), and those for saline group were as control group (n=40). They were assessed with suspension test 14 d and 28 d after born, and the expression of were NB-3 were detected with immunohistochemistry 1 d, 7 d, 14 d, 21 d, 28 d after born. Results The expression of NB-3 was different among these 3 groups, as well as the scores of suspension test (P<0.001). Conclusion Intrauterine infection increases the expression of NB-3 of neonatal rats with brain damage. The early intervention may increase persistently the expression of NB-3, and improve the motor function.

Objective To retrospectively analyze the perioperative complications of posterior lumbar interbody fusion (PLIF) for recurrent lumbar disc herniation and identify potential risk factors that correlate with those complications.Methods All of 71 patients with recurrent lumbar disc herniation were treated surgically with PLIF,discharged from our department between January 2008 and December 2014.Demographic and operation data were collected and perioperative complications were recorded.We analyzed whether the clinical factors (age,gender,BMI,co-morbidity,smoking,time of recurrence,blood loss,operation segment,operation time) were in correlation with perioperative complication by univariate analysis.Then we integrated the statistically significant indicators into Logistic regression equation to determine the related risk factors for complication.Results The study group consisted of 71 cases,including 42 males and 29 females.The age was 19 to 64 years old with an average of 50.6 years old,and the average BMI was 23.6 kg/m2.26 cases had perioperative complications,while there were two or more complications in 5 patients,and no mortalities.Neurologic deterioration or neuropathic pain (10 cases,14.1％) and dural tears (6 cases,8.5％) were the most common intraoperaitive complications.The other complications included nerve root or cauda equine injury,deep or superficial wound infection,urinary tract infection,respiratory system complication,cardio-vascular complication and delirium.Univariate analysis suggested that age,gender,co-morbidity,smoking,time of recurrence,operation segment,operation time were not associated with perioperative complication.The multivariate Logistic regression analysis showed BMI and blood loss were closely related to perioperative complication.Conclusion Complications of posterior spinal fusion surgery for recurrent lumbar disc herniation are affected by many factors.The most common complications are transient neurologic deterioration or neuropathic pain and dural tears.BMI and blood loss are independent risk factors.

Objective To compare the diagnostic performances of strain elastography (SE) and shear-wave elastography (SWE) in differentiating benign and malignant solid breast lesions. Methods From January 2015 to December 2015, 150 patients with 155 lesions were examined with SE and SWE respectively in the First Affiliated Hospital with Nanjing Medical University. Elasticity scores on a improved 5-point scale,strain ratio (SR), maximum elasticity (Emax), mean elasticity (Emean), standard deviation of the elasticity (Esd) and the lesion-to-fat elasticity ratio (Eratio) were assessed. The receiver operating characteristic (ROC) curve of SE and SWE parameters were plotted to assess the value in distinguishing benign and malignant breast lesions. The results were compared using the area under the ROC curve (AUC). The accuracy of the parameters with the largest AUC were compared between SE and SWE by McNemar test in different breast imaging reporting and data system (BI-RADS) categories. Results The AUC of elasticity scores, SR, Emax,Emean, Esd and Eratio were 0.823, 0.810, 0.877, 0.835, 0.881 and 0.853, respectively. The SE and SWE parameter with the largest AUC were elasticity scores and Esd respectively. The accuracy of Esd was higher than that of elasticity scores(86.3% vs 64.7%)in 4A lesions (2=4.639, P < 0.05). There were no significant differences in accuracy in other BI-RADS categories. Conclusions Both SE and SWE were helpful for the differentiation of benign and malignant solid breast lesions, and the diagnostic performance of SE and SWE was similar. The optimization of elastography can be achieved by combination with BI-RADS.
