Abstract
Single-cell encapsulation has become an effective strategy in cell surface engineering; however, the construction of cell wall-like layers that allow the switching of the inherent functionality of the engineered cell is still rare. In this study, we show a universal way to create an enzyme-modulated oxygen-consuming sandwich-like layer by using polydopamine, laccase, and tannic acid as building blocks, which then could generate an anaerobic microenvironment around the cell. This layer protected the encapsulated C. pyrenoidosa cell against external stresses and enabled it to switch from normal photosynthetic O2 production to photobiological H2 production. The layer showed an smaller effect on the PSII activity, which contributed a significant enhancement on the rate (0.32 μmol H2 h-1 (mg chlorophyll)-1 ) and the duration (7 d) of H2 production. This strategy is expected to provide a pathway for modulating the functionality of cells and for breakthroughs in the development of green energy alternatives.

Abstract
Objective: To investigate the expression of granulocyte-colony stimulating factor receptor (G-CSFR) in a mouse model of colitis-associated cancer (CAC), and the roles of G-CSFR positive immune cells in the development of CAC. Methods: The C57BL/6 mouse model of CAC was established by azoxymethane and dextran sulphate sodium. Three different stages in the development of CAC, including inflammation (AD1), mild dysplasia (AD2) and adenocarcinoma (AD3) were simulated. Colon tissue was digested into single cell suspension and the expressions of G-CSF and G-CSFR were analyzed by real-time PCR and fluorescence activated cell sorter (FACS). The expressions of G-CSFR on T cell, macrophage and neutrophil were analyzed by FACS. Results: The establishment of mouse model can effectively simulate the disease progression of CAC. The results of real-time PCR detection showed that the expression level of G-CSF mRNA in AD1, AD2 and AD3 groups were 1.2, 7.3 and 18.0-fold changes of the control group, respectively. The differences between AD2, AD3 and control groups were statistically significant (P<0.05). G-CSFR mRNA levels in AD1, AD2 and AD3 groups were 1.5, 2.2 and 4.5-fold changes of the control group, respectively. The difference between AD3 and control groups was statistically significant (P<0.05). FACS showed that the percentages of CD45(+) G-CSFR(+) cells in colorectal tissues of the control group, AD1, AD2 and AD3 groups were (21.84±1.77)%, (41.48±4.15)%, (44.84±8.54)% and (57.76±1.95)%, respectively.The percentages of CD45(+) G-CSFR(+) cells in AD2 and AD3 groups were significantly higher than that of control group (P<0.05). The percentages of CD45(+) G-CSFR(+) macrophage in the colorectal tissues of the control group, AD1, AD2 and AD3 groups were (21.54±5.88)%, (47.14±5.25)%, (42.49±7.80)% and (29.25±8.24)%, respectively. The percentages of CD45(+) G-CSFR(+) T cells in these groups were (30.04±6.87)%, (29.65±8.08)%, (33.75±7.37)% and (33.32±9.85)%, respectively. The percentages of CD45(+) G-CSFR(+) granulocyte were (2.39±2.10)%, (4.05±1.56)%, (3.62±2.67)% and (2.26±0.85)%, respectively (P<0.05). The percentages of G-CSFR(+) macrophage and G-CSFR(+) T cells were significantly higher than that of G-CSFR(+) granulocyte (P<0.05). The differences between AD1 and control group, AD2 and control group, AD1 and AD2 group, AD2 and AD3 group were statistically significant (P<0.05). Conclusions: The expression of G-CSFR is significantly up-regulated in the development of CAC. The enrichment of G-CSFR(+) macrophages in the colon tissue suggests G-CSFR(+) macrophages participate in the development of CAC.

Abstract
Novel mechanisms for electromagnetic wave emission in the terahertz frequency regime emerging at the nanometer scale have recently attracted intense attention for the purpose of searching next-generation broadband THz emitters. Here, we report broadband THz emission, utilizing the interface inverse Rashba-Edelstein effect. By engineering the symmetry of the Ag/Bi Rashba interface, we demonstrate a controllable THz radiation (∼0.1-5 THz) waveform emitted from metallic Fe/Ag/Bi heterostructures following photoexcitation. We further reveal that this type of THz radiation can be selectively superimposed on the emission discovered recently due to the inverse spin Hall effect, yielding a unique film thickness dependent emission pattern. Our results thus offer new opportunities for versatile broadband THz radiation using the interface quantum effects.

Abstract
Objective To study the correlation between neck circumference(NC) and umbilical artery blood flow in physiologic pregnancies. Methods One hundred and one healthy pregnant woman in the third trimester were enrolled. Anthropometric measurements and ultrasonic testing were done. Results The women with NC ≥34.7cm had a more elevated umbilical artery pulsatility index(PI) and systolic/diastolic ratio (S/D) than the women with NC <34.7cm (P<0.01). NC were positively correlated with PI(r=0.224,P=0.024) and S/D ratio(r=0.415,P=0.0001). In multivariate analysis, NC was independently associated with PI (β=0.026, P=0.016) and S/D ratio (β=0.132, P=0.0001). Conclusions Obesity has an adverse impact on feto-placetal vessels, and NC was superior to body mass index.

Abstract
Arginine methyltransferases critically regulate cellular homeostasis by modulating the functional outcome of their substrates. The protein arginine methyltransferase 5 (PRMT5) is an enzyme involved in growth and survival pathways promoting tumorigenesis. However, little is known about the biologic function of PRMT5 and its therapeutic potential in multiple myeloma (MM). In the present study, we identified and validated PRMT5 as a new therapeutic target in MM. PRMT5 is overexpressed in patient MM cells and associated with decreased progression-free survival and overall survival. Either genetic knockdown or pharmacological inhibition of PRMT5 with the inhibitor EPZ015666 significantly inhibited growth of both cell lines and patient MM cells. Furthermore, PRMT5 inhibition abrogated NF-κB signaling. Interestingly, mass spectrometry identified a tripartite motif-containing protein 21 TRIM21 as a new PRMT5-partner, and we delineated a TRIM21-dependent mechanism of NF-κB inhibition. Importantly, oral administration of EPZ015666 significantly decreased MM growth in a humanized murine model of MM. These data both demonstrate the oncogenic role and prognostic relevance of PRMT5 in MM pathogenesis, and provide the rationale for novel therapies targeting PRMT5 to improve patient outcome.

Abstract
Objective: To investigate the association between the internal exposure levels of phthalic acid esters (PAEs) and executive function (EF) of preschool children. Methods: Between October 2008 and October 2010, pregnant women who accepted pregnancy health care services in four municipal medical and health institutions in Ma'anshan city, Anhui Province, were recruited as study objects. A total of 5 084 pregnant women and 4 669 singleton live births were enrolled in this cohort. The follow-up study was conducted from April 2014 to April 2015. A total of 3 725 data-completed preschool children aged 3 to 6 years older entered in this study. The method of analysis seven metabolites of phthalates in urine was high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) and divided objects into low (P(0)-P(24)), medium (P(25)-P(74)) and high (P(75)-P(100)) groups according to their exposure concentrations. To investigate the executive function of preschool children, we used the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P). Univariate and multivariate statistical method was used to analyze the etiology association between the phthalate metabolites levels and preschool children's executive function. Results: In this study, 53.6% (1 997/3 725) of preschoolers were boys, children's age was (51.5±5.6) months. The detection rates of seven phthalate esters were: mono-n-methyl phthalate (MMP) was 99.89% (3 721/3 725); mono-ethyl phthalate (MEP) was 99.97% (3 724/3 725); mono-benzyl phthalate (MBzP) was 69.10% (2 574/3 725); mono-butyl phthalate (MBP), mono-(2-ethyl-5-oxohexyl) phthalate (MEOHP) and mono- (2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) were 100.00% and mono-ethylhexyl phthalate (MEHP) was 99.95% (3 723/3 725). The median concentrations of the seven phthalate metabolites were: 17.71, 15.36, 0.07, 155.24, 10.73, 14.67, 3.59 µg/L, respectively. The median concentrations corrected by urinary creatinine were 29.65, 26.65, 0.12, 257.73, 17.94, 24.80, 6.27 µg/g Cr, respectively. The P(25) and P(7)5 concentration of the total PAEs metabolites corrected by urinary creatinine were 1.20 µmol/g Cr and 3.04 µmol/g Cr. After adjusted the relevant demographic information: children sex, children age in month, maternal age, parental education levels, household exposure to secondhand smoke and whether the child is the only child as confounds, multivariate logistic regression model showed that the risk of inhibitory self-control index (ISCI) dysplasia in MEHHP high concentration group and MEOHP high concentration group were 1.71 and 1.54 times (OR=1.71, 95% CI: 1.11-2.62; OR=1.54, 95% CI: 1.01-2.34) than in low concentration group. The risk of ISCI dysplasia in total PAEs metabolites high concentration group was 1.55 times (OR=1.55, 95% CI: 1.00-2.38) than in low concentration group. Conclusion: Phthalates exposure may damage the executive function of preschool children.

Abstract
BACKGROUND AND OBJECTIVE Arrhythmogenic right ventricular cardiomyopathy (ARVC) is increasingly recognized in forensic practice with controversial diagnosis. Here we described the epidemiological characteristics and reported the pathogenetic mechanism, diagnostic challenges, and forensic implications of Chinese ARVC autopsy cases. METHODS Two cases of sudden cardiac death owing to ARVC were reported. Retrospective analysis were performed on such 2 cases and 45 cases of separate ARVC complete autopsy case reports through Chinese literature databases in the last 30 years. RESULTS There were 27 males and 20 females, and the mean age at death was 35 years. Sudden cardiac death was the first manifestation observed in most patients, with no previous family and medical history. Exercise, acute stress, increased cardiac workload, and ethanol are frequently involved. The mean heart weight was 393 g (range, 240-590 g), and 10 cases had relative heart hypertrophy. Microscopic abnormalities included replacement of myocardium by adipose infiltration in 68.09% cases and fibroadipose in 31.91% cases; 80.85% cases were restricted to the right ventricle (RV), whereas biventricular subtype was seen in the remaining 19.15% cases. The preliminary quantitative histology showed 60.7% of fat tissues, 12.1% of fibrosis, and 27.2% residual myocytes in RV. Inflammatory cell infiltration was found in 25.53% cases, but myocyte necrosis was found in only 1 case. In 10.64% of cases, cardiac conduction was infiltrated by fibrosis, adipose, or both. CONCLUSION In this review, the most characteristic and distinct histopathologic features that are diagnostic or highly suggestive of ARVC for forensic pathologists were identified. Combining gross and histological examinations with postmortem genetic analysis is recommended for identifying ARVC.

Abstract
Human enterovirus 71 (EV71) is the major causative agent of hand, foot, and mouth disease (HFMD), particularly in infants and children below 4 years of age. Shikonin is a bioactive compound with anti-inflammatory, antiviral, and antibacterial activities derived from the roots of the Chinese medicinal herb Lithospermum erythrorhizon. This study aimed to examine the antiviral activity of PMM-034, a shikonin ester derivative, against EV71 in rhabdomyosarcoma (RD) cells. Cytotoxicity of PMM-034 on RD cells was determined using WST-1 assay. Dose- and time-dependent effects of PMM-034 on EV71 replication in RD cells were determined using plaque reduction assay. mRNA expression levels of EV71/VP1 and pro-inflammatory cytokines (IL-1β, IL-6, IL-8, and TNF-α) were determined by real-time RT-PCR, and EV71/VP1 and phospho-p65 protein expressions were determined by western blot analysis. PMM-034 exhibited only weak cytotoxicity against RD cells. However, PMM-034 exhibited significant antiviral activity against EV71 in RD cells with 50% inhibitory concentration of 2.31 μg/mL. The VP1 mRNA and protein levels were significantly reduced in cells treated with PMM-034. Furthermore, relative mRNA expression levels of IL-1β, IL-6, IL-8, and TNF-α significantly decreased in the cells treated with PMM-034, while the phospho-p65 protein expression was also significantly lower in the treated cells. These results indicated that PMM-034 suppressed the expressions of pro-inflammatory cytokines in RD cells, exhibiting antiviral activity against EV71, as evidenced by the reduced VP1 mRNA and protein levels in PMM-034-treated cells. Thus, PMM-034 is a promising candidate for further development as an EV71 inhibitor.

Abstract
OBJECTIVE Valsartan has been reported to have the function of treating hypertension and improving the prognosis of patients. Many studies indicated that valsartan can also increase angiotensin II, andosterone and plasma renin activity (PRA). Autoantibodies against the angiotensin II type 1 receptor (AT1-AA) have been showed to increase reactive oxygen species (ROS) and calcium (Ca2+) and result in apoptosis in vascular smooth muscle cells. In this study, we attempted to explore the effect of valsartan on AT1-AA-induced apoptosis in endothelial progenitor cells. MATERIALS AND METHODS Endothelial progenitor cells (EPCs) were cultured. The cytotoxicity was determined by MTT assay. EPCs apoptosis was determined by DAPI staining and flow cytometry. Reactive oxygen species, intracellular calcium concentration and calpain activity were measured using Fluostar Omega Spectrofluorimeter. The expression of p-ERK, p-eIF-2a, CHOP, Bcl-2 and caspase-3 were detected by Western blot. RESULTS MTT assays showed valsartan significantly inhibited AT1-AA- induced decline of the viability of EPCs. DAPI staining and flow cytometry results indicated valsartan inhibited AT1-AA-induced decline of the viability of EPCs via inhibiting AT1-AA-induced apoptosis. Furthermore, the increasing of reactive oxygen species, intracellular calcium and calpain activity induced by AT1-AA in EPCs were also recovered after pre-treated with valsartan. Meanwhile, the upregulation of p-ERK, p-eIF-2a and CHOP, downregulation of Bcl-2, and activation of Caspase-3 caused by AT1-AA were reversed after pre-incubated with valsartan. CONCLUSIONS Valsartan could inhibit AT1-AA-induced apoptosis through inhibiting oxidative stress mediated ER stress in EPCs.

Abstract
Abstract
Background: Patients considering both post-mastectomy radiation (RT) and reconstruction require robust information regarding the expected outcomes of different combinations of approaches in order to make preference-concordant decisions.
Methods: In a prospective multicenter cohort study (the Mastectomy Reconstruction Outcomes Consortium, MROC, funded by NCI 1RO1CA152192) of women diagnosed with breast cancer at 11 institutions between 2012-15, we compared responses of 553 radiated and 1461 non-radiated pts who received different approaches to reconstruction. The primary dependent variables of interest were development of any breast complications (e.g. hematoma, wound infection) by one year post-reconstruction, along with satisfaction measured with the validated BREAST-Q instrument. Mixed-effects regression models assessed impact of reconstruction type and RT on the outcomes of interest. Covariate adjustment included reconstruction timing, age, extent of disease, bilateral vs unilateral treatment, chemotherapy receipt, nodal management, BMI, smoking, diabetes, race, ethnicity, education, employment, income, marital status, and hospital site.
Results: Median age was 49. Bilateral mastectomy was received by 45.6% of radiated and 53.3% of non-radiated pts (p=0.002). Autologous reconstruction was more commonly received by radiated pts (38.3% vs 25.1%, p<0.001). Immediate reconstruction was less common in radiated pts (82.6% vs 95.6%, p<0.001). By one year, at least one complication occurred in 28.8% of radiated pts (30.8% of implant pts and 25.5% of autologous pts) and 22.3% of non-radiated pts (20.4% of implant pts and 28.1% of autologous pts). Among pts with ≥2 years of follow up, a complication had occurred by 2 years in 34.1% of 331 radiated pts vs 22.5% of 946 non-radiated pts. Multivariable analysis showed immediate reconstruction, bilateral treatment, & higher BMI to be predictive of developing a complication by one year. RT effect differed by reconstruction type; RT was associated with 2.1 (95% CI = 1.45, 3.10) times higher odds of complication in implant pts, while showing no difference in autologous pts (OR=1.3, 95% CI = 0.76, 2.09). RT effect on patient outcomes also differed by reconstruction types. In implant pts, adjusted mean BREAST-Q satisfaction with breast scores were significantly lower in radiated pts than in non-radiated pts (51.5 vs. 58.0 at 1 year, p<.001; 48.9 vs. 59.8 at 2 years, p<.001), while satisfaction in autologous pts did not differ by radiation (61.3 in radiated vs. 63.5 in non-radiated at 1 year; 62.8 vs. 65.8 at 2 years). Similarly, in implant pts, satisfaction with outcomes was significantly lower in radiated versus non-radiated pts (66.5 vs. 70.8 at 1 year; p=0.03; 64.4 vs. 70.6 at 2 years, p =0.03), while there were no significant differences in autologous pts (72.7 vs. 75.2 in radiated vs. non-radiated at 1 year; 71.3 and 75.3 at year 2).
Conclusions: In the largest prospective multicenter study of outcomes of breast reconstruction to date, autologous reconstruction appears to yield superior patient-reported outcomes and lower risk of complications than implant-based approaches among patients receiving PMRT.

Abstract
Background Psoriasis patients seek information online, but little is known about their interaction with YouTube. We examined the quality of content in psoriasis-related YouTube videos and investigated their interactions with viewers.Methods YouTube was searched using the term "psoriasis." Relevant videos in English were independently categorized by two reviewers as useful, misleading, or patient view (regarding experience with psoriasis). Disagreements were settled by a third reviewer. Videos were rated on a Global Quality Scale (GQS) (1=poor, 5=excellent).Results According to our reviewers, 17% of the 47 videos were useful, 21% were misleading, and 62% represented patient views. Mean GQS scores were 4.2 ± 1.3 for useful videos, 1.7 ± 0.7 for misleading videos, and 2.2 ± 1.1 for patient view videos (p<0.001). Video views per day did not differ among the categories (p=0.65), whereas useful videos had fewest "Likes" (useful: 31 ± 55, 33 misleading: 151 ± 218, patient views: 165 ± 325, p=0.06) and comments (useful: 9.8 ± 18.3, misleading: 64.1 ± 89.7, 124.9 ± 34 199.4, p=0.009).Conclusions Useful videos were highest in quality but had similar viewership as misleading and patient view videos, with lower popularity and engagement of users compared to other categories. Physicians and psoriasis patients should be aware of this pattern when pproaching YouTube as a resource.
