Abstract
OBJECTIVE To analyze the clinical characteristics, outcome and diagnosis of two cases of imported children Zika virus infection in China. METHOD A retrospective analysis was performed on clinical characteristics, treatment and outcome of two cases of imported children with Zika virus infection in February 2016 in Enping People's Hospital of Guangdong. RESULT Two cases of children with imported Zika virus infection resided in an affected area of Venezuela, 8-year-old girl and her 6 year-old brother. The main findings on physical examination included the following manifestations: fever, rash, and conjunctivitis. The rash was first limited to the abdomen, but extended to the torso, neck and face, and faded after 3-4 d. The total number of white blood cells was not high and liver function was normal. The diagnosis of two cases of Zika virus infection was confirmed by the expert group of Guangdong Provincial Center for Disease Control and Prevention, according to the epidemiological history, clinical manifestations and Zika virus nucleic acid detection results.Treatment of Zika virus infection involves supportive care. Two Zika virus infection children had a relatively benign outcome. CONCLUSION At present, Zika virus infection in children is an imported disease in China. No specific therapy is available for this disease. Information on long-term outcomes among infants and children with Zika virus disease is limited, routine pediatric care is advised for these infants and children.

Abstract
Self-assembly of three related molecules – terephthalic acid and its hydroxylated analogues – at liquid/solid interfaces (graphite/heptanoic acid and graphite/1-phenyloctane) has been studied using a combination of scanning tunnelling microscopy and molecular mechanics and molecular dynamics calculations. Brickwork-like patterns typical for terephthalic acid self-assembly have been observed for all three molecules. However, several differences became apparent: (i) formation or lack of adsorbed monolayers (self-assembled monolayers formed in all systems, with one notable exception of terephthalic acid at the graphite/1-phenyloctane interface where no adsorption was observed), (ii) the size of adsorbate islands (large islands at the interface with heptanoic acid and smaller ones at the interface with 1-phenyloctane), and (iii) polymorphism of the hydroxylated terephthalic acids’ monolayers, dependent on the molecular structure and/or solvent. To rationalise this behaviour, molecular mechanics and molecular dynamics calculations have been performed, to analyse the three key aspects of the energetics of self-assembly: intermolecular, substrate–adsorbate and solvent–solute interactions. These energetic characteristics of self-assembly were brought together in a Born–Haber cycle, to obtain the overall energy effects of formation of self-assembled monolayers at these liquid/solid interfaces.

Abstract
AIMS The aim was to investigate the impact of PPARG and APOE gene single nucleotide polymorphisms (SNPs) and additional gene- gene interaction on late-onset Alzheimer's disease (LOAD) risk based on Chinese Han population. METHODS A total of 928 participants (466 males, 462 females), with a mean age of 81.3 ± 16.4 years old, were included in the study, including 460 LOAD patients and 468 normal controls participants. Logistic regression was performed to investigate association between SNP and LOAD risk and generalized multifactor dimensionality reduction (GMDR) was used to analysis the gene-gene interaction. RESULTS Logistic regression analysis showed that LOAD risk was significantly higher in carriers of G allele of the rs405509 polymorphism than those with AA (AG+ GG versus AA, adjusted OR (95%CI) =1.54(1.20-1.89), and higher in carriers of G allele of the rs1805192 polymorphism than those with CC (CG+ GG versus CC, adjusted OR (95%CI) =1.32(1.16-2.43). We also found that there was a potential gene-gene interaction between rs405509 and rs1805192. Participants with AG or GG of rs405509 and CG or GG of rs1805192 genotype have the highest AD risk, compared to participants with AA of rs405509 and CC of rs1805192 genotype, OR (95%CI) was 2.62(1.64 -3.58), after covariates adjustment. CONCLUSIONS G allele of the rs405509 of APOE and G allele of the rs1805192 of PPAR G polymorphism were associated with increased LOAD risk, and participants with AG or GG of rs405509 and CG or GG of rs1805192 genotype have the highest AD risk.

Abstract
We demonstrate mirrorless lasers based on all organic nanostructure fabricated by seven- and nine-beam interference using low contrast material, holographic polymer dispersed liquid crystals (H-PDLC). A finite-difference time-domain (FDTD) simulation is used to study the transmission of quasicrystal. The wavelengths of lasing peak are determined by both of local structure of quasicrystal that the pumping light experienced as well as the photoluminescence of laser dye doped. Features of mirrorless laser from quasicrystal based on H-PDLC include directional light source, low threshold, simple fabrication process, low cost and tunability. These properties make H-PDLC photonic quasicrystal promising for a new type of all organic miniature lasers.

Abstract
According to the AOAC 998.12 method, honey is considered to contain significant C-4 sugars with a C-4 sugar content of >7%, which are naturally identified as the adulteration. However, the authenticity of honey with a C-4 sugar content of <0% calculated by the above method has been rarely investigated. A new procedure to determine δ(13)C values of honey, corresponding extracted protein and individual sugars (sucrose, glucose, and fructose), δ(2)H and δ(18)O values, sucrose content, and reducing sugar content of honey using an elemental analyzer and liquid chromatography coupled to isotope ratio mass spectroscopy, was first developed to demonstrate the authenticity of honey with a C-4 sugar content of <0%. For this purpose, 800 commercial honey samples were analyzed. A quite similar pattern on the pentagonal radar plot (isotopic compositions) between honey with -7 < C-4 sugar content (%) < 0 and 0 < C-4 sugar content (%) < 7 indicated that honey with -7 < C-4 sugar content (%) < 0 could be identified to be free of C-4 sugars as well. A very strong correlation is also observed between δ(13)C honey values and δ(13)C protein values of both honey groups. For the δ(18)O value, the C-4 sugar content (%) < -7 group has lower (p < 0.05) values (16.30‰) compared to other honey, which could be a useful parameter for adulterated honey with a C-4 sugar content (%) < -7. The use of isotopic compositions and some systematic differences permits the honey with a C-4 sugar content of <0% to be reliably detected. The developed procedure in this study first and successfully provided favorable evidence in authenticity identification of honey with a C-4 sugar content of <0%.

Abstract
SUMMARY Osteocyte is the orchestrator of bone remolding and decline in osteocyte autophagy is involved in senile osteoporosis. Our results suggested that rapamycin, at least in part by activating osteocyte autophagy, reduced the severity of age-related bone changes in trabecular bone of old male rats. INTRODUCTION Previous literatures have showed that osteocyte is the orchestrator of bone remolding and age-related decline in osteocyte number is associated with senile osteoporosis. Autophagy is an important cellular protective mechanism which can preserve osteocyte viability and failure of autophagy in osteocyte with age has been linked to senile osteoporosis. The purpose of this study was to explore whether rapamycin, one activator of autophagy, has protective effects on senile osteoporosis through inducing osteocyte autophagy. METHODS Fifty-two 24-month-old male Sprague-Dawley (SD) rats were randomly divided into two groups. Rapamycin (1 mg/kg weight/day) or DMSO vehicle control was administered intraperitoneally for 12 weeks. BMD and bone microstructure were determined by Micro-CT. Fluorochrome labeling of the bones was performed to measure the mineral apposition rate (MAR). TRAP staining was performed to evaluate osteoclast number. The plasma levels of bone turnover markers were also analyzed. The effects of rapamycin on osteocyte autophagy were determined by immunohistochemistry, Western blot, and q-PCR. TUNEL was used to determine the prevalence of osteocyte apoptosis. RESULTS Micro-CT evaluation demonstrated that rapamycin had a protective effect on age-related bone loss in trabecular bone. Besides, rapamycin resulted in an obvious increase of MAR and a decrease of osteoclast number in contrast to the control group. Furthermore, rapamycin also induced autophagy in osteocyte demonstrated by increased LC3-positive osteocyte and increased LC3 turnover. In addition, rats treated with rapamycin exhibited decreased apoptosis of osteocyte determined by TUNEL. CONCLUSIONS These results suggested that rapamycin, at least in part by activating osteocyte autophagy, reduced the severity of age-related bone changes in trabecular bone of old male rats. Therefore, rapamycin might be a feasible therapeutic approach for senile osteoporosis.

Abstract
Here, we describe the dramatic response of a patient with an ETV6-NTRK3-driven mammary analogue secretory carcinoma to treatment with a pan-Trk inhibitor, and the development of acquired resistance linked to a novel NTRK3 mutation that interferes with drug binding. This case emphasizes how molecular profiling can identify therapies for rare diseases and dissect mechanisms of drug resistance. Background Mammary analogue secretory carcinoma (MASC) is a recently described pathologic entity. We report the case of a patient with an initial diagnosis of salivary acinic cell carcinoma later reclassified as MASC after next-generation sequencing revealed an ETV6-NTRK3 fusion. Patients and methods This alteration was targeted with the pan-Trk inhibitor entrectinib (Ignyta), which possesses potent in vitro activity against cell lines containing various NTRK1/2/3 fusions. Results A dramatic and durable response was achieved with entrectinib in this patient, followed by acquired resistance that correlated with the appearance of a novel NTRK3 G623R mutation. Structural modeling predicts that this alteration sterically interferes with drug binding, correlating to decreased sensitivity to drug inhibition observed in cell-based assays. Conclusions This first report of clinical activity with TrkC inhibition and the development of acquired resistance in an NTRK3-rearranged cancer emphasize the utility of comprehensive molecular profiling and targeted therapy for rare malignancies (NCT02097810).

Abstract
Low driving voltage is achieved in full color reflective display based on polymer-stabilized blue phase liquid crystal (PS-PBLC), by doping a small amount of ferroelectric nanoparticles. Both reflectance spectra of PS-PBLC with and without BaTiO₃ ferroelectric nanoparticles are studied under different applied external voltages. Superior to PS-PBLC without ferroelectric nanoparticles, the vertical driving electric fields of PS-PBLC with 0.4 wt.% BaTiO₃ ferroelectric nanoparticles are dramatically reduced by more than 70% for red, green and blue cells. The proposed approach would accelerate the practical application of full color PS-BPLC reflective display.

Abstract
We present the design, description, calibration procedure, and an analysis of systematic effects for an apparatus designed to measure the rotation of the plane of polarization of a transversely polarized slow neutron beam as it passes through unpolarized matter. This device is the neutron optical equivalent of a crossed polarizer/analyzer pair familiar from light optics. This apparatus has been used to search for parity violation in the interaction of polarized slow neutrons in matter. Given the brightness of existing slow neutron sources, this apparatus is capable of measuring a neutron rotary power of dϕ/dz = 1 × 10(-7) rad/m.

Abstract
The effects of 5 factors (template DNA, Mg(2+), dNTPs, Taq DNA polymerase, and primer) on the polymerase chain reaction (PCR) were investigated to optimize the start codon targeted polymor-phism (SCoT)-PCR system of Dactylis glomerata L., using an orthogo-nal design L16 (4(5)). A suitable SCoT-PCR system for D. glomerata was established; the 20 μL reaction volume contained 3.0 mM Mg(2+), 0.2 mM dNTPs, 1.0 U Taq DNA polymerase, 0.2 μM primer, 20 ng tem-plate DNA, and 2 μL 10X buffer. Each factor had a different effect on the amplification reaction, and the concentration of dNTPs had the larg-est effect on the SCoT-PCR system. We tested 10 orchardgrass samples to determine and verify the stability of the reaction system. The results showed that amplified bands from diverse materials were clear, stable, and rich in polymorphisms, indicating that the optimized system was very stable.
