In this study,we aimed to study the pattern visual evoked potentials (P-VEPs) in two eyes with varying visual acuity in one eye and to provide an objective estimation of visual acuity by comparing P-VEPs in one and two eyes.Thirty subjects were chosen,who had one eye with an acuity of 5.0,4.85,4.6,4.0,or scieropia and obstructed vision and the other eye with an acuity of 5.0,respectively.P-VEPs were detected under the large grating stimuli at 3×4 spatial frequency,moderate grating stimuli (12× 16 spatial frequency) and small grating stimuli (48×64 spatial frequency).Under large grating stimuli,there was no significant difference in P100 peak latency between the groups,nor was there a significant difference between the amplitude of two eyes and the amplitude of one normal-vision eye.Under moderate and small grating stimuli,there was a significant difference in P100 peak latency between the group with both eyes having an acuity of 5.0 and the group with visual acuity below 4.0 in one eye.There was a significant difference in P100 amplitude between the group with visual acuity of 5.0 in both eyes and the group with one normal-vision eye.There was no significant difference in the amplitude of two eyes and the amplitude of one normal-vision eye between any other two groups.In forensic identification,characteristics and variability of P-VEPs in one and two eyes can be used to identify malingering or decline in visual acuity.

OBJECTIVETo investigate the risk factors for anastomotic infectious complications after bowel resection in patients with Crohn disease.

METHODSClinical data of 124 patients with Crohn disease undergoing bowel resection between January 1990 and October 2012 were analyzed retrospectively. The risk factors were identified by χ(2) test and Logistic regression.

RESULTSFourteen patients (12.3%, 14/114) developed anastomotic infectious complications in the postoperative period, including anastomotic leak (n=7), intra-abdominal abscess (n=6), and enterocutaneous fistula (n=1). Crohn disease activity index (CDAI)>150 (OR=2.185, 95%CI:1.098-6.256, P=0.040), steroid usage (OR=2.674, 95%CI:1.118-8.786, P=0.027), and the presence of preoperative abscess/fistula (OR=3.447, 95%CI:1.254-10.462, P=0.014) were identified as independent risk factors of anastomotic infectious complications. In the absence of these 3 risk factors, the rate of anastomotic infectious complication was 5.7% (3/53), which increased to 11.4% (4/35) when one risk factor was present, 21.1% (4/19) when two risk factors were present, and 42.9% (3/7) when all the 3 risk factors were present.

CONCLUSIONSCDAI>150, steroid usage and preoperative abscess/fistula are associated with higher rates of anastomotic infectious complications following bowel resection for Crohn disease. A prudent management should be carried out if risk factors can not be eliminated preoperatively.

A new viral sampling concentration device was designed which was equipped with a new cationic filter membrane-Nanoceram suitable for field sampling. Norovirus Genegroup II was detected from environmental water with the aid of this device. The effects on virus recovery of prefiltration, various second-concentration methods, and different eluants were investigated through pre-experiment. The concentration optimized process, and the optimal concentration process were then determined. The results showed that the prefiltration had a profound effect on virus recovery, and two second-concentration method: PEG-NaC1 precipitation and celite adsorption, had almost the same concentration effects. The Na2 HPO4 solution of 0.15 mol/L was selected as the final eluant to elute the adsorbed Nuorovirus from the celite. The virus recovery of Nanoceram was determined to be 3.02%. Finally, successful detection of Norovirus GII in sewage from Yangqiao River, Fengtai District, Beijing was acheived. All these data had shown that the Naneceram filter concentration method could concentrate Norovirus from environmental water with a steady effects.

Chronic spinal cord lesions (CSCL) which result in irreversible neurologic deficits remain one of the most devastating clinical problems. Its pathophysiological mechanism has not been fully clarified. As a crucial factor in the outcomes following traumatic spinal cord injury (SCI), the blood-spinal cord barrier (BSCB) disruption is considered as an important pathogenic factor contributing to the neurologic impairment in SCI. Vascular endothelial growth factor (VEGF) is a multirole element in the spinal cord vascular event. On one hand, VEGF administrations can result in rise of BSCB permeability in acute or sub-acute periods and even last for chronic process. On the other hand, VEGF is regarded to be correlated with angiogenesis, neurogenesis and improvement of locomotor ability. Hypoxia inducible factor-1 (HIF-1) is a primary regulator of VEGF during hypoxic conditions. Therefore, hypoxia-mediated up-regulation of VEGF may play multiple roles in the BSCB disruption and react on functional restoration of CSCL. The purpose of this article is to further explore the relationship among HIF-1, hypoxia-mediated VEGF and BSCB dysfunction, and investigate the roles of these elements on CSCL.

OBJECTIVETo evaluate the predictive value of quantitative examination via contrast-enhanced ultrasonography on the activity of Crohn disease at endoscopy.

METHODSA total of 59 cases with Crohn disease in People's Hospital of Lishui City between January 2009 and December 2010 were collected prospectively and underwent both colonoscopy and contrast-enhanced ultrasonography. According to the Simple Endoscopic Score, Crohn disease was divided into inactive and active disease by colonoscopy. To assess the vascularization of the involved bowel loop in a region expected to be seen at colonoscopy, the contrast agent uptake was measured by using quantitative analysis. Measurement of contrast enhancement was assessed as the percentage of increase in wall brightness in regions of interest (ROI). The receiver operating characteristic curve was used to evaluate the value of contrast agent uptake in predicting the severity determined at endoscopy.

RESULTSColonoscopy showed active lesions in 45 cases and inactive lesions in 14 cases, in whom the percentages of increase of brightness were (90±32)% and (41±29)% respectively. At a threshold value of 45% for the percentage of increase of brightness, sensitivity, specificity and accuracy of predicting the severity at endoscopy were 95.6%, 78.6% and 91.5%, the Youden index was 0.74, and area under curve was 0.846.

CONCLUSIONSQuantitative measurement of bowel enhancement by using contrast-enhanced ultrasonography can discriminate between active and inactive Crohn disease at endoscopy. Contrast-enhanced ultrasonography may be a useful technique to monitor the activity of Crohn disease.
