Background and PurposezzAcute disseminated encephalomyelitis (ADEM) is an infammatory demyelinating disorder that predominantly afects children. Previous studies have mostly involved children in Western developed countries. MethodszzTis study retrospectively reviewed the clinical profles of ADEM in adult Chinese patients. ResultszzADEM occurred during summer and autumn in about two-thirds of the 42 included patients. Prior infection was found in fve patients and no preimmunization was recorded. Te most frequent clinical presentations were alterations in consciousness (79%) and behavior changes (69%), followed by motor defcits (64%) and fever (50%). About one-quarter (26%) of the patients showed positive results for oligoclonal bands, and about half of them exhibited increases in the IgG index and 24-hour IgG synthesis rate. Magnetic resonance imaging showed white- and gray-matter lesions in 83% and 23% of the patients, respectively. Steroids were the main treatment, and full recovery occurred in 62% of the patients, with residual focal neurological defcits recorded in a few patients. Afer a mean follow-up period of 3.4 years, two patients exhibited recurrence and one patient exhibited a multiphasic course. One patient was diagnosed with multiple sclerosis (MS). ConclusionszzWith the exception of the seasonal distribution pattern and prior vaccine rate, the clinical profles of ADEM in adult Chinese patients are similar to those in pediatric populations. No specifc markers are available for distinguishing ADEM from MS at the initial presentation. Careful clinical evaluations, cerebrospinal fuid measurements, and neuroradiological examinations with long-term follow-up will aid the correct diagnosis of ADEM.

Background: The possibility that electromagnetic fields (EMF) exposure may increase male breast cancer risk has been discussed for a long time. However, arguments have been presented that studies limited by poor quality could have led to statistically significant results by chance or bias. Moreover, data fo the last 10 years have not been systematically summarized. Methods and Results: To confirm any possible association, a meta-analysis was performed by a systematic search strategy. Totals of 7 case-control and 11 cohort studies was identified and pooled ORs with 95% CIs were used as the principal outcome measures. Data from these studies were extracted with a standard meta-analysis procedure and grouped in relation to study design, cut-off point, exposure assessment method, adjustment and exposure model. A statistical significant increased risk of male breast cancer with EMF exposure was defined (pooled ORs = 1.32, 95% CI = 1.14-1.52, P < 0.001), and subgroup analyses also showed similar results. Conclusions: This meta-analysis suggests that EMF exposure may be associated with the increase risk of male breast cancer despite the arguments raised.

Sepsis is a systemic inflammatory responsesyndrome caused by severe infections. Astilbin is a dihydroflavonolderivative found in many medicinal and foodplants with multiple pharmacological functions. To investigatethe effects of astilbin on sepsis-induced acute lunginjury (ALI), cecal ligation and puncture was performed onrats to establish a sepsis-induced ALI model; these ratswere then treated with astilbin at different concentrations. Lung injury scores, including lung wet/dry ratio, proteinleakage, myeloperoxidase activity, and inflammatory cellinfiltration were determined to evaluate the effects ofastilbin on sepsis-induced ALI. We found that astilbintreatment significantly attenuates sepsis-induced lunginjury and improves survival rate, lung injury scores, lungwet/dry ratio, protein leakage, myeloperoxidase activity,and inflammatory cell infiltration. Astilbin treatment alsodramatically decreased the production of inflammatorycytokines and chemokines in bronchoalveolar lavage fluid. Further, astilbin treatment inhibited the expression andproduction of macrophage inhibitory factor (MIF), whichinhibits the inflammatory response. Collectively, these datasuggest that astilbin has a protective effect against sepsisinducedALI by inhibiting MIF-mediated inflammatoryresponses. This study provides a molecular basis for astilbinas a new medical treatment for sepsis-induced ALI.

Adverse drug reactions (ADRs) are a serious threat to people's lives and property safety. Currently, drug instructions are the main way for people to obtain information on ADRs. Due to drugs’ limited pre-market clinical trials, adverse reactionsstated in drug instructions are often not sufficient. Avisualization platform for ADRs isput forward to address this problem. Adverse drug events (ADEs) data include actual clinical adverse reactions of drugs detected by drug monitoring administrationand can compensate for the insufficiency of drug instructions. Based on drug instructions and ADEs data, ADRVis isrealized by data analysis, model design and JAVA programming. ADRVis presentsthe relationship of 656 common drugs and their respective ADRs. Three case studies show that the platform has the capacities of visual presentation of ADRs and early warning of drug risks.The platform can provide people more rich information about drugs and help them understand ADRs more accurately and comprehensively.

Objective: We sought to distinguish lipid plaques using a CT quantitative pixel density histogram, based on the pathological diagnosis of lipid cores as the gold standard. Materials and Methods: Eight patients awaiting heart transplantation due to end-stage coronary heart disease underwent coronary CT angiography (CCTA) spectroscopy prior to heart transplantation; coronary artery pathological analysis was performed for all patients. Lipid-core plaques were defined pathologically as manifesting a lipid core diameter > 200 μm, a circumference > 60 degrees, and a cap thickness < 450 μm. The percentage distributions of CT pixel attenuation ≤ 20, 30, 40, and 50 HU were calculated using quantitative histogram analysis. Results: A total of 271 transverse sections were co-registered between CCTA and pathological analysis. Overall, 26 lipid cores and 16 fibrous plaques were identified by pathological analysis. There was no significant difference in median CT attenuation between the lipid and fibrous plaques (51 HU [interquartile range, 46–63] vs. 57 HU [interquartile range, 50–64], p = 0.659). The median percentage of CT pixel attenuation ≤ 30 HU accounted for 11% (5–17) of lipid-core plaques and 0% (0–2) of fibrous plaques (p < 0.001). The sensitivity and specificity of the method for diagnosing lipid plaques by the average CT pixel attenuation ≤ 30 HU were 80.8% and 87.5%, respectively. The area under the receiver operator characteristics curve was 0.898 (95% confidence interval: 0.765–0.970; 3.0% was the best cut-off value). The diagnostic performance was significantly higher than those of the average pixel CT attenuation percentages ≤ 20, 40, and 50 HU and the mean CT attenuation (p < 0.05). Conclusion: In in vivo conditions, with the pathological lipid core as the gold standard, quantification of the percentage of average CT pixel attenuation ≤ 30 HU in the histogram can be useful for accurate identification of lipid plaques.

Two new coumarin glucosides, 11-O-β-D-glucopyranosyl thamnosmonin (1) and 12-O-β-D-glucopyranosyl gosferol (2), were isolated from the roots of Angelica apaensis. Their structures were elucidated spectroscopically. Both compounds showed weak inhibitory effects on rabbit platelet aggregation induced by PAF, AA and APD.

A simple and effective technique to reduce the overall fuel cell polarization resistance was introduced on a conventionally sintered YSZ electrolyte by creating a hybrid microstructure using low-intensity CO2 laser scanning methods. After laser modification of the YSZ electrolyte surface on the cathode side, the overall polarization resistance was reduced from 513 to 124 Ω cm2, and the maximum power density was increased by 28% from 1.86 to 2.38 mW/cm2 at 450 °C. This improvement was due to the enhanced surface kinetics by higher grain boundary density on the YSZ surface from recrystallization after laser scanning.
