Abstract
BACKGROUND Six-monthly hepatocellular carcinoma (HCC) screening in cirrhotic patients has been recommended since 2011. HCC prognosis is associated with diagnosis at an early stage. We examined the prevalence and correlates of 6-monthly HCC surveillance in a cohort of HCV-infected cirrhotic patients. METHODS Data were obtained from the medical records of patients receiving care from four hospitals between January 2011 and December 2016. Frequencies and logistic regression were conducted. RESULTS Of 2,933 HCV-infected cirrhotic patients, most were ≥ 60 years old (68.5%), male (62.2%), White (65.8%), and had compensated cirrhosis (74.2%). The median follow-up period was 3.5 years. Among these patients, 10.9% were consistently screened 6 monthly and 21.4% were never screened. Patients with a longer history of cirrhosis (AOR = 0.86, 95% CI = 0.80-0.93) were less likely to be screened 6 monthly while decompensated cirrhotic patients (AOR = 1.39, 95% CI = 1.06-1.81) and cirrhotic patients between 18 and 44 years (AOR = 2.01, 95% CI = 1.07-3.74) were more likely to be screened 6 monthly compared to compensated cirrhotic patients and patients 60 years and older respectively. There were no significant differences by race, gender, or insurance type. CONCLUSION The prevalence of consistent HCC surveillance remains low despite formalized recommendations. One in five patients was never surveilled. Patients with a longer history of cirrhosis were less likely to be surveilled consistently despite their greater HCC risk. Improving providers' knowledge about current HCC surveillance guidelines, educating patients about the benefits of consistent HCC surveillance, and systemic interventions like clinical reminders and standing HCC surveillance protocols can improve guideline-concordant surveillance in clinical practice.

Abstract
AIM To evaluate the value of using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) derived parameters to differentiate thymic carcinoma and thymic lymphoma based on semi-quantitative and quantitative models. MATERIALS AND METHODS Twenty-nine pathologically confirmed anterior mediastinum tumours in 29 patients were enrolled in this retrospective study, including 15 thymic carcinoma and 14 lymphoma patients. All the patients underwent pre-treatment mediastinum DCE-MRI. Both semi-quantitative and quantitative parameters were calculated and the volume transfer constant Ktrans, the flux rate constant between extravascular extracellular space and plasma kep, the extravascular extracellular volume fraction ve were obtained based on a modified Tofts model. DCE-MRI derived parameters were compared between thymic carcinoma and thymic lymphoma groups. RESULTS Thymic carcinoma had significantly lower kep (p=0.040) and higher ve (p=0.018) than thymic lymphoma; however, there were no significant differences on Ktrans and semi-quantitative parameters between the two groups. ve had the highest area under the curve (cut-off value, 0.282; area under the curve, 0.748; sensitivity, 71.4%; specificity, 80%). The combination of kep and ve could increase the diagnostic performance significantly (area under the curve, 0.752; sensitivity, 57.1%; specificity, 93.3%). CONCLUSION DCE-MRI derived parameters may have value in the differentiating thymic carcinoma and thymic lymphoma.

Abstract
African Americans (AAs) are an admixed population with widely varying proportion of West African ancestry (WAA). Here we report the correlation of WAA to gene expression and DNA methylation in AA-derived hepatocytes, a cell type important in disease and drug response. We perform mediation analysis to test whether methylation is a mediator of the effect of ancestry on expression. GTEx samples and a second cohort are used as validation. One hundred and thirty-one genes are associated with WAA (FDR < 0.10), 28 of which replicate and represent 220 GWAS phenotypes. Among PharmGKB pharmacogenes, VDR, PTGIS, ALDH1A1, CYP2C19, and P2RY1 nominally associate with WAA (p < 0.05). We find 1037 WAA-associated, differentially methylated regions (FDR < 0.05), with hypomethylated genes enriched in drug-response pathways. In conclusion, WAA contributes to variability in hepatocyte expression and DNA methylation with identified genes previously implicated for diseases disproportionately affecting AAs, including cardiovascular (PTGIS, PLAT) and renal (APOL1) disease, and drug response (CYP2C19).

Abstract
Objective: To compare the blood flow around the optic disc and related factors in patients with acute and chronic non-arteritic anterior ischemic optic neuropathy (NAION) and healthy volunteers with small disc cups under the same anatomical structure. Methods: This was a prospective case-control study. NAION patients with unilateral onset and healthy volunteers of the same phase were included in the study conducted at the Department of Ophthalmology of Peking Union Medical College Hospital between February 2017 and September 2018. Patients with a course of ≤ 3 months were categorized in the acute phase of NAION, and those with a course of >3 months were in the chronic phase of NAION. Healthy volunteers were in the control group. All subjects underwent the examination of best corrected visual acuity converted to logarithm of the minimum angle of resolution (LogMAR), measurement of non-contact intraocular pressure, slit lamp examination, small pupil fundus examination, and axial measurement. Optical coherence tomography was used to measure the thickness of retinal nerve fiber layers (RNFL) and retinal ganglion cell complex (GCC). Optical coherence tomography angiography was used to measure the vessel density around the optic disc. NAION patients underwent the visual field examination. Analysis of variance, non-parametric Mann-Whitney U test and Spearman coefficient was used for statistical analysis. Results: This study included 16 patients with acute phase of NAION, aged (57±9) years, 6 males and 10 females. There were 17 patients with chronic disease, aged (56±10) years, 7 males and 10 females. There were 15 healthy controls, aged (57±10) years old, 6 males and 9 females. There were no significant differences in age and gender between the groups (both P>0.05). The RNFL and the GCC in the NAION chronic phase group were significantly thinner than those in the acute phase group [(78±38) μm vs. (191±99) μm, (75±19) μm vs. (98±28) μm; t=4.389, 2.758; both P<0.05]. The cup/disc area ratio, cup/disc vertical diameter ratio and cup/disc horizontal diameter ratio in the chronic phase group were larger than those in the acute phase group [0.18 (0.11, 0.31) vs. 0.05 (0.01, 0.18), 0.45 (0.39, 0.56) vs. 0.22 (0.11, 0.41), 0.39 (0.28, 0.54) vs. 0.20 (0.07, 0.42)], and the difference was statistically significant (U=212.000, 208.000, 205.000; all P<0.05). Compared with the optic disc vessel density in the control group (53%±6%), there was a significant decrease in the acute phase group and the chronic phase group (45%±7%, 41%±8%; t=3.705, 4.940; both P<0.01). The blood vessel density in the nasal inferior of the chronic phase group was significantly lower than that in the acute phase group (36%±8% vs. 42%±7%, P=0.039), other sections didn't have significant difference (all P>0.05). There were tortuous capillaries in 8/16 of the acute phase cases, with a low blood flow density and visual field defect in relative positions. Correlation analysis showed that the whole density and peripapillary density in the NAION patients were negatively correlated with LogMAR, mean visual field defect, cup/disc area ratio, focal loss of volume of GCC and general loss of volume of GCC (r=-0.510, -0.733, -0.372, -0.532, -0.648; all P<0.01), but positively correlated with GCC and RNFL thickness (r=0.604, 0.508; both P<0.01). Conclusions: The optic disc vessel density in the acute phase and chronic phase of NAION is significantly reduced. The vessel density in the nasal area of the chronic phase is significantly reduced compared with the acute phase. The vessel density is correlated with visual acuity, visual field defect, disc indexes, thickness of RNFL and GCC. (Chin J Ophthalmol, 2019, 55: 677-686).

Abstract
Importance Many studies have compared outcomes for incomplete revascularization (IR) among patients undergoing percutaneous coronary interventions (PCI), but little is known about whether outcomes are related to the nature of the IR. Objective To determine whether some coronary vessel characteristics are associated with worse outcomes in patients with PCI with IR. Design, Setting, and Participants New York's PCI registry was used to examine mortality (median follow-up, 3.4 years) as a function of the number of vessels that were incompletely revascularized, the stenosis in those vessels, and whether the proximal left anterior descending artery was incompletely revascularized after controlling for other factors associated with mortality for patients with and without ST-elevation myocardial infarction (STEMI). This was a multicenter study (all nonfederal PCI hospitals in New York State) that included 41 639 New York residents with multivessel coronary artery disease undergoing PCI in New York State between January 1, 2010, and December 31, 2012. Exposures Percutaneous coronary interventions, with complete and incomplete revascularization. Main Outcomes and Measures Medium-term mortality. Results For patients with STEMI, the mean age was 62.8 years; 26.2% were women, 11.9% were Hispanic, and 81.5% were white. For other patients, the mean age was 66.6 years, 29.1% were women, 11.3% were Hispanic, and 79.1% were white. Incomplete revascularization was very common (78% among patients with STEMI and 71% among other patients). Patients with IR in a vessel with at least 90% stenosis were at higher risk than other patients with IR. This was not significant among patients with STEMI (17.18% vs 12.86%; adjusted hazard ratio [AHR], 1.16; 95% CI, 0.99-1.37) and significant among patients without STEMI (17.71% vs 12.96%; AHR, 1.15; 95% CI, 1.07-1.24). Similarly, patients with IR in 2 or more vessels had higher mortality than patients with completely revascularization and higher mortality than other patients with IR among patients with STEMI (20.37% vs 14.39%; AHR, 1.35; 95% CI, 1.15-1.59) and among patients without STEMI (20.10% vs 12.86%; AHR, 1.17; 95% CI, 1.09-1.59). Patients with proximal left anterior descending artery vessel IR had higher mortality than other patients with IR (20.09% vs 14.67%; AHR, 1.31; 95% CI, 1.04-1.64 for patients with STEMI and 20.78% vs 15.62%; AHR, 1.11; 95% CI, 1.01-1.23 for patients without STEMI). More than 20% of all PCI patients had IR of 2 or more vessels and more than 30% had IR with more than 90% stenosis. Conclusions and Relevance Patients with IR are at higher risk of mortality if they have IR with at least 90% stenosis, IR in 2 or more vessels, or proximal left anterior descending IR.

Abstract
Objective: To investigate the consequences of the thickness of ganglion cell layer (GCL) and visual field defect of non-functional pituitary adenoma with chiasm compression. Methods: A case control study. The study included 40 (80 eyes) non-functional pituitary adenoma patients in Peking Union Medical College Hospital from March 2015 to February 2017. Twenty patients (no visual field defect group, 40 eyes) of them were detected to be chiasm compressed or touched by the adenoma with no visual field defect detected, and the other 20 patients (visual field defect group, 40 eyes) were the sex-and-age matched pituitary adenoma patients with bitemporal heminopsia. This study also included 20 (control group, 40 eyes) sex-and-age matched healthy controls. The para-papillary retinal nerve fiber layer (RNFL) thickness in 6 quadrants including nasal, temporal, nasal superior, temporal superior, nasal inferior and temporal inferior as well as the macular GCL thickness and ganglion cell-inner plexiform layer (GCIPL) thickness in 4 quadrants including nasal superior, nasal inferior, temporal superior and temporal inferior were measured. The non-parametric test was used to compare the RNFL, GCL and GCIPL thickness among the three groups. Results: The mean age among the three groups was (46±10) years and the difference among the three groups was not significant (P=0.88). The sex ratio of the three groups was 9∶11 (male∶female) and the difference among the three groups was not significant. The mean axial length among the three groups was (23.22±0.90) mm and the difference among the three groups was not significant (P=0.51). The thickness of para-papillary RNFL of temporal superior, temporal, nasal superior, nasal, nasal inferior quadrants and whole circumference was significantly thinner in the visual field defect group than the control group [(129.88±28.64) μm, (63.63±26.84) μm, (88.08±32.16) μm, (50.68±19.99) μm, (92.48±25.06) μm, and (85.00±20.65) μm vs. (141.10±18.95) μm, (79.12±16.78) μm, (113.68±21.28) μm, (69.67±14.23) μm, (117.80±31.32) μm, and (102.80±9.68) μm, t=2.26, 3.06, 4.14, 4.84, 4.25, 4.88, all P<0.05]. In the nasal quadrant, the para-papillary RNFL of the no visual field defect group was significantly thinner compared with the control group [(61.45±9.83) μm vs. (69.67±14.23) μm, t=2.97, P<0.05]. The total GCL thickness was (30.48±5.42) μm in the visual field defect group, (31.35±2.77) μm in the no visual field defect group, thinner than that in the control group [(33.32±2.92) μm, t=2.92, 3.62; both P<0.05]. The total GCIPL thickness showed no significant difference among the three groups (P=0.07). In the superior and inferior temporal quadrants, the GCL and GCIPL thickness showed no significant difference among the three groups (all P>0.05). In the superior and inferior nasal quadrants, the GCL thickness was (29.41±5.97) μm, and (28.47±5.13) μm in the visual field defect group, (31.15±3.27) μm and (30.61±2.96) μm in the no visual field defect group, and (34.23±3.16) μm and (32.97±2.78) μm in the control group. The GCL thickness in the nasal quadrant was thinner in the visual field defect group (t=4.45, 4.82)and the no visual field defect group(t=4.23, 3.63) than in the control group (all P<0.01). However, no significant difference in GCL thickness was detected between the visual field defect group and the no visual field defect group (both P>0.05). In the superior and inferior nasal quadrants, the GCIPL thickness was (54.06±10.50) μm and (51.77±9.18) μm in the visual field defect group, (58.03±4.00) μm and (56.23±5.37) μm in the no visual field defect group, and (62.26±7.11) μm and (59.39±6.64) μm in the control group. The GCIPL thickness was thinner in the nasal quadrant in the visual field defect group than in the control group (t=3.95, 4.20, both P<0.01). Only in the Superior nasal quadrant, the GCIPL was significantly thinner in the no visual field defect group than the control group (t=3.25, P<0.01). Conclusion: The optic GCL may get thinner in pituitary nonfunctional adenoma with chiasm compression patients without the RNFL layer thinning and visual field defect.

Abstract
OBJECTIVE To study the effect of 3-n-butylphthalide (NBP) on neuronal apoptosis in rats with cerebral infarction (CI) through the p38/mitogen-activated protein kinase (MAPK) pathway. MATERIALS AND METHODS A total of 30 rats were divided into control group (healthy rats, n=10), model group (CI rat model, n=10), and NBP group (CI rat model + intraperitoneal injection of NBP, n=10). Then, the neurological function, degree of cerebral ischemia, apoptosis of brain tissues, the protein and messenger ribonucleic acid (mRNA) expressions of p-p38 and MAPK in brain tissues were detected using the neurological score, 2,3,5-triphenyltetrazolium chloride (TTC) staining, Reverse Transcription-Polymerase Chain Reaction (RT-PCR), terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay, and Western blotting, respectively. RESULTS In NBP group, the neurological score was significantly lower than in model group, and the difference was statistically significant (p<0.05). The results of TTC staining revealed that the area of the white region in brain slices was significantly larger in model group than in control group, indicating the successful establishment of middle cerebral artery occlusion (MCAO) model. Compared with model group, NBP group had a smaller area and lighter color of the white region in brain slices, suggesting that NBP markedly reduces the MCAO-induced CI. The apoptosis rate in NBP group was higher than in control group (p<0.05), but lower than in model group (p<0.05), while it was higher in model group than in control group (p<0.05). The protein expressions of p38 and MAPK in NBP group were higher than in control group (p<0.05), but lower than in model group (p<0.05), while they were higher in model group than in control group (p<0.05). Moreover, the mRNA expressions of p38 and MAPK were lower in control group than in model group (p<0.05), while they were higher in model group than in NBP group (p<0.05), but there was no significant difference in the mRNA expression of p38 between NBP group and control group (p>0.05). CONCLUSIONS NBP alleviates neuronal apoptosis in CI by down-regulating the p38 signal and inhibiting the expression of MAPK, thereby treating CI.

Abstract
BACKGROUND Recent studies have reported mixed findings regarding the inverse provider volume-outcome relationship for percutaneous coronary interventions (PCIs). METHODS We included patients who underwent PCIs in New York during December 2012-November 2015. Using risk-adjusted in-hospital/30-day mortality rate and appropriateness of PCI, we tested for a continuous relationship and a variety of annual PCI volume cut points at hospital and operator levels in investigating volume-outcome relationships. RESULTS There were 144,196 patients undergoing PCI procedures from 63 non-federal hospitals. There was a significant inverse association between risk-adjusted mortality and both annual hospital PCI volume and annual operator PCI volume. However, we did not find that there was an inverse hospital volume-outcome relationship for the 2013 ACCF/AHA/SCAI's hospital PCI volume cutoff value of 200 per year (AOR, 1.15, 95% CI, 0.88-1.51, P = 0.32) or a significant inverse operator volume-outcome relationship using the operator PCI volume cutoff value of 50 per year (AOR, 0.89, 95% CI, 0.70-1.12, P = 0.32) or for any other practical volume cutoffs. There was also no significant volume-outcome relationship for STEMI patients. Higher volume hospitals (>400) and operators (>200) tended to perform a higher percentage of inappropriate PCI procedures than their lower volume counterparts. CONCLUSION There were no significant PCI volume-mortality relationships for either hospitals or operators for any practical volume cuts. Higher volume hospitals and operators were associated with higher percentages of inappropriate PCIs.

Abstract
Improving the insulating nature of sulfur and retaining the soluble polysulfides in sulfur cathodes are crucial for realizing the practical application of lithium-sulfur batteries (LSBs). Biomass-based carbon is becoming increasingly popular for fabricating economical and efficient cathodes for LSBs owing to its unique structure. Herein, we report a facile strategy to transform bovine bone with an organic-inorganic structure into cellular hierarchical porous carbon via carbonization and KOH activation, followed by CoS2 modification through hydrothermal treatment. The synthesized composite can load abundant sulfur and produce a dual effect of "physical confinement and chemical entrapment" on polysulfides. The conductive carbon frame with the developed porous structure provides adequate space to accommodate sulfur and physically suppress the shuttle effect of polysulfides. The embedded half-metallic CoS2 sites can chemically anchor the polysulfides and enhance the electrochemical reaction activity as well. Owing to the multifunctional structure and dual restraint effect, the designed electrode exhibits enhanced electrochemical properties including high initial capacity (1230.9 mAh g-1 at 0.2 C), improved cycling stability and enhanced rate capability.
