Abstract
BACKGROUND AND AIMS The American Heart Association has outlined seven cardiovascular health (CVH) metrics, including smoking, body mass index, physical activity, dietary pattern, total cholesterol, and fasting plasma glucose, to define and monitor CVH status. Our study was to evaluate the global CVH in adults. METHODS AND RESULTS We searched PubMed, Embase, Cochrane Central Register of Controlled Trials, and reference lists of relevant articles for studies published between 1 January 2010 and 30 June 2018. Included studies should report the proportions of ideal status for the seven CVH metrics and/or provide the prevalence of overall poor (having 0-2 ideal metrics) or ideal (having 5-7 ideal metrics) CVH status in adults. 88 articles were identified: 75 for the prevalence of ideal CVH metrics, 58 for the proportion of overall poor CVH status, and 55 for the proportion of overall ideal CVH status. Smoking had the highest prevalence of ideal status (69.1%) while dietary pattern has the lowest (12.1%). 32.2% and 19.6% of participants had overall poor and ideal CVH, respectively. Females and young adults had better CVH status when compared to males and older adults. There existed regional variations in ideal CVH metrics and overall CVH status. The overall CVH status had improved over study time. CONCLUSION The prevalence of ideal status was low for some metrics, such as dietary pattern, and the overall CVH status was still unsatisfactory. We should continue to measure the CVH status and carry out lifestyle interventions to improve the CVH status in the whole population.

Abstract
Objective: To detect the expression level of YES-associated protein 1 (YAP) in hepatocellular carcinoma (HCC) cell lines and investigate its effects on the proliferation activity and the sensitivity to sorafenib in HCC cells. Methods: Western blot was used to detect the protein expression levels of YAP in SMMC-7721, SK-Hep-1, HepG-2, Huh7 and the normal liver cell line L-O2. YAP specific small interfering RNA (si-YAP) or YAP expression plasmid were transfected in SK-Hep-1 or Huh7 cells, respectively. Cell counting kit-8 (CCK-8) test was used to detect the cell proliferation activity and the cell cycle test was conducted by flow cytometry. SK-Hep-1 and SK-Hep-1 si-YAP cells were subcutaneously injected into the nude mice which were sequentially treated by intragastric administration of sorafenib, and the tumor growth in vivo were observed and compared. Results: The expression of YAP was upregulated in HCC cell lines. Deletion of YAP expression significantly decreased the survival rate of SK-Hep-1 cells [(78.5±0.3)% vs (92.3±0.2)%, P=0.025]. Knockdown of YAP significantly increased the percentage of G(0)/G(1)-phase cells [ (65.4±3.3) % vs (55.7±3.4) %, P=0.039]. On the contrary, upregulation of the YAP expression in Huh7 cells significantly increased the cell survival rate [(81.2±1.3)% vs (62.5±1.1)%, P=0.013] and reduced the percentage of G(0)/G(1)-phase cells [(38.2±3.8)% vs (48.8±2.9)%, P=0.019]. The survival rate of SK-Hep-1 cells treated by si-YAP combined with sorafenib was (31.13±1.79)%, significantly lower than (48.87±0.58) % of SK-Hep-1 cells treated by sorafenib alone (P=0.001), while overexpression of YAP attenuated the inhibitory effect of sorafenib on the survival of Huh7 cells [(69.98±2.94) % vs (53.53±1.93)%, P=0.001]. The tumor weights of SK-Hep-1 group, sorafenib alone group, SK-Hep-1 si-YAP group and SK-Hep-1 si-YAP combined with sorafenib group were (0.96±0.08) g, (0.62±0.08) g, (0.70±0.06) g and (0.27±0.02) g, respectively. The tumor weights of sorafenib alone group and SK-Hep-1 si-YAP group were significantly lower than that of SK-Hep-1 group (P=0.012 and P=0.031, respectively). The tumor weight of SK-Hep-1 si-YAP combined with sorafenib group was significantly lower than that of SK-Hep-1 si-YAP group (P=0.001). Conclusions: The expression of YAP is upregulated in HCC cell lines, which regulates the proliferation, cell cycle, and sensitivity to sorafenib of HCC cells. YAP is a potential molecular target for HCC treatment.

Abstract
Emerging evidence has linked the exosomes to many immunological disorders, including infectious diseases. However, knowledge regarding the role of exosomes in Helicobacter pylori infection is limited. Here, we show that serum exosomes from chronic gastritis patients with H. pylori infection (Hp exosomes) stimulate the expression of the soluble interleukin (IL)-6 receptor (sIL-6R), which is involved in IL-6 trans-signalling in gastric epithelial cells. Interestingly, sIL-6R up-regulates expression of the proinflammatory cytokine IL-1α, and the neutralization of sIL-6R suppresses IL-1α secretion. Thus, Hp exosomes regulate IL-1α expression via sIL-6R-mediated IL-6 trans-signaling. Altogether, this study reveals a novel perspective in which exosomes play a vital role in immunological mechanisms during H. pylori infection.

Abstract
A novel κ-carrageenase gene (CgkB) has been cloned from Pedobacter hainanensis NJ-02 and expressed heterologously in Escherichia coli BL21 (DE3). It consisted of 1935 bp and encoded 644 amino acid residues with a molecular weight of 71·61 kDa. The recombinant enzyme showed maximal activity of 2458 U mg-1 at 40°C and pH 8·0. Additionally, it could retain more than 70% of its maximal activity after being incubated at pH of 5·5-10·0 below 40°C. K+ and a broad range of NaCl can activate the enzyme. The Km and Vmax of CgkB was 2·4 mg ml-1 and 126 mmol mg-1 min-1 . The ESI-MS analysis of hydrolysates indicated that the enzyme can endolytically depolymerize the carrageenan into tetrasaccharides and hexasaccharides. The results indicated that the enzyme with high activity could be a valuable enzyme tool to produce carrageenan oligosaccharides with various activities. SIGNIFICANCE AND IMPACT OF THE STUDY Enzymatic preparation of carrageenan oligosaccharides has drawn increased attention due to their various physiological activities. It is urgent to explore enzyme tools with higher activity and better stability. In this work, a novel κ-carrageenase was identified and characterized from marine bacterium Pedobacter hainanensis NJ-02. The enzyme with high activity could be a valuable tool to produce carrageenan oligosaccharides with various activities.

Abstract
Keratosis follicularis spinulosa decalvans (KFSD) is an X-linked condition characterized by keratotic follicular papules and progressive alopecia, which is caused by mutations in the MBTPS2 gene. We carried out a genetic study on a child who was suspected clinically to have KFSD. Sanger sequencing was performed to detect mutations in the entire coding region of MBTPS2. A novel missense mutation (c.599C>T) was identified in the patient, confirming a diagnosis of KFSD. We reviewed related cases with MBTPS2 mutations for evidence of genotype-phenotype correlations.

Abstract
AIM To determine the prevalence of adverse clinical outcomes, the rates of healthcare utilization, and the incidence of post-partum Type 2 diabetes in refugees with gestational diabetes (GDM), compared with other immigrants and non-immigrants. METHODS A population-based cohort study was conducted using healthcare databases in Ontario, Canada. Over 40 000 women with GDM having singleton live births between 2002 and 2014 were identified. We identified GDM adverse outcomes such as macrosomia, pre-eclampsia and respiratory distress syndrome. Antenatal and newborn healthcare utilization were ascertained. Women were then followed for diagnosis of diabetes post-partum. RESULTS Both refugees and other immigrants had a lower rate than non-immigrants of many adverse GDM outcomes, including pre-eclampsia [relative risk (RR) 0.65, 95% confidence interval (95% CI) 0.44-0.95 and 0.61, 95% CI 0.52-0.72, respectively], preterm birth (RR 0.87, 95% CI 0.75-0.995 and 0.85, 95% CI 0.80-0.91, respectively), and respiratory distress syndrome (RR 0.83, 95% CI 0.70-0.97 and 0.78, 95% CI 0.72-0.84, respectively). However, refugees were less likely to attend well-baby care in time for the first routine vaccination (RR 0.92, 95% CI 0.88-0.95). Incidence of post-partum diabetes was high in all groups, but refugee women were at increased risk (hazard ratio 1.23, 95% CI 1.11-1.37). CONCLUSIONS Despite different circumstances leading to migration, refugees have a similar 'healthy immigrant effect' to other immigrants, with respect to adverse GDM outcomes. However, newborns of refugees were less likely to have well-baby care, and refugee women were also at especially high risk of developing diabetes post-partum. These are both important public health issues.

Abstract
During a magnetic storm on 23 June 2015, several very intense substorms took place, with signatures observed by multiple spacecraft including DMSP and Magnetospheric Multiscale (MMS). At the time of interest, DMSP F18 crossed inbound through a poleward expanding auroral bulge boundary at 23.5 h magnetic local time (MLT), while MMS was located duskward of 22 h MLT during an inward crossing of the expanding plasma sheet boundary. The two spacecraft observed a consistent set of signatures as they simultaneously crossed the reconnection separatrix layer during this very intense reconnection event. These include (1) energy dispersion of the energetic ions and electrons traveling earthward, accompanied with high electron energies in the vicinity of the separatrix; (2) energy dispersion of polar rain electrons, with a high-energy cutoff; and (3) intense inward convection of the magnetic field lines at the MMS location. The high temporal resolution measurements by MMS provide unprecedented observations of the outermost electron boundary layer. We discuss the relevance of the energy dispersion of the electrons, and their pitch angle distribution, to the spatial and temporal evolution of the boundary layer. The results indicate that the underlying magnetotail magnetic reconnection process was an intrinsically impulsive and the active X-line was located relatively close to the Earth, approximately at 16-18 RE.

Abstract
Reticulate pigmentary disorders are a group of disorders characterized by hyper- and/or hypopigmented macules with varying sizes and amounts of pigment. Some of the disorders are heritable, such as Dowling-Degos disease, dyschromatosis universalis hereditaria, dyschromatosis symmetrica hereditaria, reticulate acropigmentation of Kitamura and X-linked reticulate pigmentary disorder. Although each condition possesses unique phenotypic characteristics and the prognosis for each is somewhat different, there is a large degree of overlap between the disorders and therefore they are difficult to differentiate in the clinical setting. This updated review provides a clinical and molecular delineation of these genetic reticulate pigmentary disorders and aims to establish a concise diagnostic strategy to allow clinical dermatologists to make an accurate diagnosis, as well as to provide useful information for clinical and genetic counselling.

Abstract
Improving terahertz (THz) emission from graphene is a challenge for graphene-based THz photonics as graphene demonstrates a weak light-matter interaction. With a unique ultra-black surface structure, vertically grown graphene (VGG) is proposed to enhance the light-matter interaction and further enhance THz emission. Herein, enhanced THz radiation is observed by THz time-domain emission spectroscopy from VGG compared with single-layer graphene. The radiated THz amplitude shows a linear dependence on pump power, which demonstrates a second order nonlinear effect. Considering the symmetry of VGG on a substrate, we can exclude the optical rectification effect and photogalvanic effect (PGE) by the D6h point group with centrosymmetry. Thus we analyze the transient photocurrent related to THz emission only by the photon drag effect (PDE). The polarization-sensitive THz radiation signals are wave-vector reliant and demonstrate cos 2φ and sin 2φ dependence on the polarization angles of the pump laser. This is consistent with the theoretical analysis of PDE. Our results show the enhanced, ultrafast, broadband THz radiation property of VGG, which paves the way for high performance THz emitters and THz detectors based on graphene materials.

Abstract
Systemic anaplastic large cell lymphomas (sALCLs) comprise a heterogeneous group of relatively rare T-cell non-Hodgkin lymphomas that are characterized by CD30 expression. Anaplastic lymphoma kinase (ALK)-positive ALCL is a type of sALCL that commonly involves lymph nodes and extranodal sites. Skin involvement usually presents as tumours, nodules and ulcers. We describe an unusual case of ALK-positive ALCL in an 11-year-old Chinese boy, who initially presented with skin eruption with rapid progression and poor prognosis. This case emphasizes the value of clinical factors to predict the prognosis of ALK-positive sALCL, and we recommend close collaboration between dermatologists, pathologists and haematologists/oncologists to assure the correct diagnosis and treatment.
