Abstract
Objective:To synthesize cisplatin loaded and cell penetrating peptide TAT decorated magnetic nanoparticles and to observe the inhibiting effect in vitro on nasopharyngeal cancer therapy.Method:The aldehyde sodium alginate coated magnetic nanoparticles (ASA-MNPs) was prepared as the drug delivery system, which was covalently attached by PEGylation TAT (TAT-ASA-MNPs) via condensation of aldehyde with amino group and then coordinated with cisplatin (TAT-ASA-MNPs@CDDP). The complex was characterized by H-NMR and FT-IR. The cell penetrating ability and biocompatibility were observed by means of fluorescent tags. The inhibited effect on nasopharyngeal cancer CNE-2 cells was measured by cellular toxicity research and flow cytometry.Result:The H NMR and FT-IR of TAT-ASA-MNPs exhibited the characteristic peaks of TAT, PEG as well as ASA. The dynamic light scattering showed the hydrodynamic diameter of the complex was(145.9±1.5)nm. Zeta potential was(-21.66±1.24)mV and the drug loading rate was(25.03±3.05)%. Fluorescent labeling assay revealed that FITC marked TATASAMNPs was quickly taken up by CNE-2 cells. Cytotoxicity experiment on 293T cells displayed high survival rate (>70%) after cultured for 72h. Negative hemagglutination reflected decent biocompatibility. In vitro cytotoxicity test and cell apoptosis assay exhibited obvious inhibition on CNE-2 cell with TATASAMNPs@CDDP at low concentration of cisplatin compared to ASA-MNPs@CDDP (P<0.05).Conclusion:TAT-ASA-MNPs showed decent biocompatibility while distinctly inhibit CNE-2 cells in vitro study.

Abstract
OBJECTIVE Axial spondyloarthritis (SpA) is a chronic inflammatory disease characterized by back pain and stiffness. The objective of this study was to determine whether golimumab is superior to placebo in patients with nonradiographic axial SpA. METHODS This phase III, double-blind, randomized, placebo-controlled trial was performed to evaluate subcutaneous golimumab (50 mg) versus placebo in patients ages ≥18 years to ≤45 years who had active nonradiographic axial SpA according to the Assessment of SpondyloArthritis international Society (ASAS) criteria for ≤5 years since diagnosis, high disease activity, and an inadequate response to or intolerance of nonsteroidal antiinflammatory drugs. Patients were randomized 1:1 to receive golimumab or placebo subcutaneously every 4 weeks. The primary end point was 20% improvement according to the ASAS criteria (ASAS20) at week 16. Key secondary end points were an ASAS40 response, ASAS partial remission, 50% improvement in the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and change in the Spondyloarthritis Research Consortium of Canada (SPARCC) magnetic resonance imaging (MRI) index for sacroiliac (SI) joint inflammation (SPARCC score). RESULTS Of the 198 patients randomized, 197 were treated (97 received golimumab, and 100 received placebo). The mean age of the patients was 31 years, and 57.1% were male. At baseline, the mean ± SD BASDAI was 6.5 ± 1.5, the mean ± SD ASDAS was 3.5 ± 0.9, and the mean ± SD SPARCC score was 11.3 ± 14.0. The primary end point, an ASAS20 response, was achieved by significantly more patients in the golimumab group compared with the placebo group (71.1% versus 40.0%; P < 0.0001). An ASAS40 response was also achieved by significantly more patients in the golimumab group compared with the placebo group (56.7% versus 23.0%; P < 0.0001). The incidence of adverse events did not differ meaningfully between groups. CONCLUSION Patients with active nonradiographic axial SpA treated with golimumab had significantly greater improvement in symptoms compared with patients treated with placebo. Golimumab was well tolerated and had a favorable risk/benefit profile.

Abstract
OBJECTIVES To compare the characteristics of younger and older subjects with diffuse cutaneous systemic sclerosis (SSc) entering clinical trials. METHODS Subjects were participants in three randomised interventional trials that shared relative uniformity of demographics and disease characteristics. Only subjects with diffuse cutaneous systemic sclerosis were evaluated. To maximise possible differences, the lowest (age<38 years) and highest quartiles (age>53 years) were used, and a total of 264 diffuse cutaneous SSc (dcSSc) subjects were identified. For the comparison between the two age groups, generalised linear mixed or linear models with adjustment for population norms, demographics and medications were employed to assess differences attributable to subject age. RESULTS After adjustment for population norms and study effects, differences in diastolic blood pressure, alkaline phosphatase, AST, and creatinine phosphokinase (CK) were found between the two age groups. After further adjustment for demographics, disease duration and medications, older SSc patients still had significantly higher alkaline phosphatase (11 U/L higher), and lower CK (76 U/L lower) than younger patients (p<0.003 for all). All other variables were not significantly different in the two age groups. CONCLUSIONS Clinical baseline differences exist between younger and older patients with SSc. However, after adjustment for population norms and potential confounders, including medications, only differences in alkaline phosphatise (only 11U/L) and CK (76 U/L) remain. Overall, older patients with SSc in clinical trials seem to be more similar to younger patients than was previously thought.

Abstract
The measurements for predicting early deterioration of stroke patients is controversial. We studied laboratory measurements and previously identified risk factors to identify factors or predictors of early deterioration after stroke. A prospective observational study of 196 patients with first-time acute ischemic stroke was performed. Demographic data, patient histories, laboratory measurements, and initial stroke severity assessments were recorded. Patients with early deterioration in National Institutes of Health Stroke Scale scores (increase ≥3 points within 3 days) were defined as having stroke-in-evolution (SIE). Thirty patients were diagnosed with SIE. An initial National Institutes of Health Stroke Scale score of 12 or higher, a Glasgow Coma Scale score of 12 or lower, d-dimers more than 1000, or blood urea nitrogen/creatinine (BUN/Cr) ratio higher than 15 were more frequent in SIE patients. After multivariate analysis, only a BUN/Cr higher than 15 was independent predictor of SIE. These patients were 3.41-fold more likely to have SIE (P = .008). These findings suggest that BUN/Cr may be a novel predictor of SIE, potentially useful in emergency departments.

Abstract
BACKGROUND AND PURPOSE Abscesses caused by aerobic bacteria (aerobic abscesses) can simulate intracranial glioblastomas multiforme (GBMs) in MR imaging appearance and single voxel (SV) proton MR spectroscopy of the central cavity. The purpose of our study was to determine whether MR spectroscopic imaging (SI) can be used to differentiate aerobic abscesses from GBMs. Our hypothesis was that metabolite levels of choline (Cho) are decreased in the ring-enhancing portion of abscesses compared with GBMs. MATERIALS AND METHODS Fifteen patients with aerobic abscesses were studied on a 1.5T MR scanner using an SV method and an SI method. Proton MR spectra of 15 GBMs with similar conventional MR imaging appearances were used for comparison. The resonance peaks in the cavity, including lactate, cytosolic amino acids, acetate, succinate, and lipids, were analyzed by both SV MR spectroscopy and MRSI. In the contrast-enhancing rim of each lesion, peak areas of N-acetylaspartate (NAA), choline (Cho), lipid and lactate (LL), and creatine (Cr) were measured by MRSI. The peak areas of NAA-n, Cho-n, and Cr-n in the corresponding contralateral normal-appearing (-n) brain were also measured. Maximum Cho/Cr, Cho/NAA, LL/Cr-n, and Cho/Cho-n and minimum Cr/Cr-n and NAA/NAA-n ratios in abscesses and GBMs were compared using the Wilcoxon rank sum test. After receiver operating characteristic curve analysis, diagnostic accuracy was compared. RESULTS Cytosolic amino acid peaks were found in the cavity in 7 of 15 patients with aerobic abscesses. Means and SDs of maximum Cho/Cr, Cho/NAA, LL/Cr-n, and Cho/Cho-n and minimum Cr/Cr-n and NAA/NAA-n ratios were 3.38 +/- 1.09, 3.88 +/- 2.13, 2.72 +/- 1.45, 1.98 +/- 0.53, 0.53 +/- 0.16, and 0.44 +/- 0.09, respectively, in the GBMs, and 1.77 +/- 0.49, 1.48 +/- 0.51, 2.11 +/- 0.67, 0.81 +/- 0.21, 0.48 +/- 0.2, and 0.5 +/- 0.15, respectively, in the abscesses. Significant differences were found in the maximum Cho/Cr (P = .001), Cho/NAA (P = .006), and Cho/Cho-n ratios (P < .001) between abscesses and GBMs. Diagnostic accuracy was higher by Cho/Cho-n ratio than Cho/Cr and Cho/NAA ratios (93.3% versus 86.7% and 76.7%). CONCLUSION Metabolite ratios and maximum Cho/Cho-n, Cho/Cr, and Cho/NAA ratios of the contrast-enhancing rim were significantly different and useful in differentiating aerobic abscesses from GBMs by MRSI.

Abstract
The color Doppler ultrasound has been used to evaluate hepatic vein (HV) outflow insufficiency based on flow velocity and waveforms. In our experience, some cases with flat waveforms are clinically asymptomatic. The parameters of HV flow velocity and waveforms are not always correlated with clinical problems. So, we proposed that total HV flow volume (HVFV) may be a more reliable index. From August 2001 to July 2003, 31 cases among 48 adult-to-adult living related transplants of a right liver graft had one HV anastomosis. HV velocity, waveforms, and HVFV were compared both before and after transplantation. We set the minimal HVFV ratio at 80% based on the original HVFV before graft retrieval. There was no significant difference in HVFV before liver graft retrieval between the 2 groups, but there was a significant change after transplantation. There were no cases of HV insufficiency among group A patients (>80%), whose HVFV ranged from 397 to 1181 mL/min with ratios from 75% to 180% (mean 115%). In group B, there were 4 complicated cases with prolonged severe ascites (<80%) with HVFV ratios from 56% to 76% (mean 66%). Fisher exact test showed a great significance (P < .001). Thus the preliminary criteria of 80% minimal HVFV ratio allows detection of HV insufficiency for further interventional management.

Abstract
PURPOSE Previous studies have suggested that black women may be less likely than white women to be offered and to take hormone replacement therapy (HRT). Thus, race and other factors associated with physician recommendation of HRT that may influence women's decisions about HRT were examined. METHODS Data were from a baseline assessment of participants in a randomized controlled trial designed to evaluate the efficacy of a tailored decision-aid on HRT decision-making. We telephone interviewed 581 Durham women ages 45-54. The association of race and other factors with reported physician recommendation of HRT was tested using chi(2) and logistic regression analysis. RESULTS Overall, 45% of women surveyed reported that their physician recommended HRT; black women were significantly less likely than white women to report being advised about HRT (35% vs. 48%, respectively, P < 0.005). Additional factors associated with being recommended HRT included older age, being postmenopausal, having had a hysterectomy, having thought about the benefits of HRT, and being satisfied with information about HRT. CONCLUSIONS Black women are less likely than white women to receive physician recommendation of HRT. Racial differences in patient-provider communication about HRT exist and thus require greater diligence on the part of health care providers to minimize such a gap.

Abstract
BACKGROUND Chemoprevention is the use of pharmacologic or natural agents to inhibit the development of cancer. Tamoxifen citrate is the only approved chemopreventive agent for breast cancer. We sought to determine whether women are interested in taking a drug to prevent breast cancer and to assess the relationship between objective and subjective breast cancer risk and interest in chemoprevention. METHODS We conducted telephone interviews (November 3, 1997, to May 6, 1998) among a community sample of women aged 40 to 45 and 50 to 55 years enrolled in a randomized controlled trial to evaluate the efficacy of a tailored mammography decision aid. Objective breast cancer risk was measured using the 5-year Gail score. Subjective breast cancer risk was measured using perceptions of absolute risk, perceptions of comparative risk, and worry about getting breast cancer. At 12-month follow-up (November 2, 1998, to July 20, 1999), we measured interest in taking a drug to prevent breast cancer. RESULTS Among the 1273 women surveyed, 23% were interested in taking a drug to prevent breast cancer; 8% were potentially eligible for tamoxifen therapy (5-year Gail score > or = 1.66%). Eligibility for chemoprevention, based on the 5-year Gail score, was not associated with interest in taking a drug to prevent breast cancer. Women who were worried about breast cancer were 3 times more likely to be interested in taking a drug to prevent breast cancer than those who were not worried. CONCLUSION Women's interest in chemoprevention might arise more from worries about getting breast cancer than from their objective risk factors.

Abstract
From 1991 to 1995, we reviewed the medical records of 200 pediatric patients with systemic malignancies to study the occurrence of neurologic complications and their treatment. A total of 25 patients with neurologic complications were found. Complications included intracranial metastasis (one patient), intraspinal metastasis (one), spinal epidural compressions (three), leptomeningeal metastases (six), metabolic encephalopathy (10), opportunistic infection (one), cerebrovascular disorders (three), treatment complications (six) and paraneoplastic syndromes (two). Ten patients had seizures. One patient with acute lymphoblastic leukemia (ALL) had the unusual complication of cytomegalovirus retinitis and glaucoma. Seven patients had neurologic features at presentation. ALL was the most common malignancy (56%) and neuroblastoma (20%) was the second. Neurologic deficits are frequently seen in pediatric patients with systemic malignancies and can, in fact, be the presenting signs. Early diagnosis and treatment is important to prevent further neurologic disability.

Abstract
This is a case report of a patient with hepatic adenoma who had a magnetic resonance imaging (MRI) appearance mimicking that of adenomatous hyperplasia. The adenoma was hyperintense on T1-weighted image (T1WI) and hypointense on T2-weighted image (T2WI). Pathologically, iron deposition in hepatocytes and Kupffer cells was proved by Prussian blue stain that caused hypointensity on T2WI. Iron deposition in hepatic adenomatous hyperplasia has been documented in the past, but there are no reports of siderotic adenoma in the literature. We suggest that siderotic hepatic adenoma be included in the differential diagnosis when MRI appearance is hyperintense on T1WI and hypointense on T2WI.

Abstract
PURPOSE The authors report their experience with the treatment of intrahepatic bile duct strictures associated with hepatolithiasis. METHODS Eighty patients had multiple postoperative retained intrahepatic duct stones trapped behind intrahepatic biliary strictures. Before stone extraction, the strictures were opened gradually by semirigid dilators, followed by stent placement to create enough patency for stone removal. All procedures were carried out through the T-tube tracts and were aided by cholangioscopy and electrohydraulic lithotripsy. RESULTS Complete clearance of stones was achieved in 69 patients. Failure to dilate the strictures was due to acute and multiple ductal angulations. These included the right posterior inferior intrahepatic duct at its junction with the left intrahepatic ducts when it was more than 2 cm distal to the hepatic bifurcation, when the angle between the T-tube tract and the common bile duct was smaller than 90 degrees, and when stones were located in peripheral intrahepatic ducts with more than five angulations. CONCLUSION This technique is considered safe and effective for complicated hepatolithiasis with intrahepatic biliary strictures.
