    ABSTRACT: Pymetrozine is a selective insecticide with a unique chemical structure and mode to control hemipteran and homopteran. While pymetrozine has brought great benefits to crop production by killing insects, its residues in soil may have a detrimental effect on environment. Therefore, it is of great importance to investigate its behaviors in soil. In this study, the sorption and desorption of pymetrozine on six Chinese soils were investigated using a batch equilibrium approach to understand its mobile behavior in the soils. Both sorption and desorption isotherms of pymetrozine were in good agreement with the Freundlich model. The sorption coefficient K F varied between 3.37 and 58.32 mL·g−1 and the sorption isotherms were nonlinear, with 1/n ranging from 0.57 to 0.91. A regression equation was proposed to predict the sorption of pymetrozine on six different soil samples: log K F = 4.3708 − 4.5709 × log (pH in 0.01mol·L−1 CaCl2) + 0.4700 × log OC% + 0.0057 × sand (%) + 0.0022 × CEC(clay), with R 2 = 0.9982. The organic carbon content of soil positively affected the sorption of pymetrozine, but soil pH had a negative effect on the sorption. Additionally, effects of CaCl2 concentration, soil to solution ratio and pesticide form were investigated. The sorption was promoted with an increase in soil to solution ratio and a decrease in CaCl2 concentration. The possible variation of the five formulated products of pymetrozine was also investigated.

    ABSTRACT: This paper describes the facile and surfactant-free synthesis of faceted Pt-Ni alloy nanoparticle electrocatalysts using neat N-formylpiperidine as a new type of solvent. Unlike the widely-used colloidal synthesis based on long-carbon chain surfactants, nanoparticles made in neat N-formylpiperidine possess a directly accessible surface for electrocatalytic reactions, making it a very attractive alternative solvent. The area-specific oxygen reduction reaction (ORR) activity is much higher than the commercial Pt/C catalyst reference and reaches a maximum of 1.12 mA cm(-2) for the Pt-Ni alloy nanoparticles. We observed that the freshly formed Pt-Ni alloy could have controllable bulk and near surface compositions under the same initial reaction conditions and precursor ratio. The change in the composition could be attributed to the effect of CO on the formation of uniform nuclei at the initial stage, and a different deposition rate between Pt and Ni metals during the growth. The well-defined Pt-Ni nanoparticle catalysts show strong composition-dependent catalytic behavior in ORR, highlighting the important role of controlling the growth kinetics in the preparation of active Pt-Ni ORR catalysts.

    ABSTRACT: Atrazine (ATR) is a pesticide widely used for controlling weeds for crop production. Crop contamination with ATR negatively affects crop growth and development. This study presents the first genome-wide single-base-resolution maps of DNA methylation in ATR-exposed rice. Widespread differences were identified in CG and non-CG methylation marks between the ATR-exposed and ATR-free (control) rice. Most of DNA methyltransferases, histone methyltransferases and DNA demethylase were differentially regulated by ATR. We found more genes hypermethylated than those hypomethylated in the regions of upstream, genebody and downstream under ATR exposure. A stringent group of 674 genes (p < 0.05, two-fold change) with a strong preference of differential expression in ATR-exposed rice was identified. Some of the genes were identified in a subset of loss of function mutants defective in DNA methylation/demethylation. Provision of 5-azacytidine (AZA, inhibitor of DNA methylation) promoted the rice growth and reduced ATR content. By UPLC/Q-TOF-MS/MS, 8 degraded products and 9 conjugates of ATR in AZA-treated rice were characterized. Two of them has been newly identified in this study. Our data show that ATR-induced changes in DNA methylation marks are possibly involved in an epigenetic mechanism associated with activation of specific genes responsible for ATR degradation and detoxification.

    ABSTRACT: Background: Impaired Toll-like receptor 2 (TLR2) function has been associated with the pathogenesis of atopic dermatitis (AD). However, there are only few studies reporting on the TLR2-induced immunological responses of circulating leucocytes of AD patients. We thus investigated the expression and secretion of Th1, Th2 and Th17/22 cytokines triggered by TLR2 ligands in human peripheral blood mononuclear cells (PBMCs) from AD patients. Expression of TLR2, 1, 6 and high-affinity receptor for IgE (FcεRI) were further investigated to evaluate the outcome of immune response in AD. Methods: Expression of TLR2, 1, 6 and FcεRI in PBMCs from AD patients and healthy individuals were measured by qPCR. Subsequent to stimulation with TLR2 ligands PGN and Pam3CSK4, expression and secretion of Th1, Th2 and Th17/22 cytokines were investigated by qPCR and ELISA. Results: The levels of TLR2, 1, 6 mRNA were not altered in both groups of subjects while that of FcεRI was increased in AD patients. Subsequent to the activation by TLR2 ligands, PBMCs from AD patients significantly released less IFN-γ, IL-17F and IL-22 than those from healthy controls while no detectable level of release was observed with the other cytokines. In contrast, significantly higher levels of mRNA expression for TNF-α, IL5, IL-17A and IL-22 were observed in TLR2 activated PBMCs of AD patients than those of healthy control. Conclusions: PBMCs from AD patients are defective in the secretion of Th1 and Th17/22 cytokines in response to TLR2 ligands. The inconsistent increased expression of the mRNA for the corresponding Th1 cytokines and the Th2 cytokines IL-5 suggested that there may be alterations of downstream signaling events in the cytokine release mechanisms of PBMCs that are associated with the development of AD.

    ABSTRACT: Pt epitaxial layer on a nanoparticle with twinned structure and well-defined shape is highly desirable in order to achieve high performance in both catalytic activity and durability towards oxygen reduction reaction (ORR). However, it remains tremendously challenging to produce conformal, heterogeneous, twinned nanostructures due to the high internal strain and surface energy of Pt. In addition, these twinned nanostructures may be subject to degradation in highly corrosive ORR environments due to the high energy of twin boundary. Here we report the synthesis of Au-Pt core-shell star-shaped decahedra bounded mainly by {111} facets, in which Pt shells with controlled thickness epitaxially grew on Au cores with a five-fold twinned structure. The incorporation of amine group decreases the surface energy of Pt by strong adsorption, and thus facilitates the epitaxial growth of Pt on Au core instead of the dendritic growth. In addition, Br- ion could largely stabilize the {111} facets of Pt, which prevent the formation of spherical nanoparticles. The Au-Pt core-shell decahedra with thicker Pt shell exhibited enhanced ORR properties in terms of activity and durability. Specifically, AuPt1.03 star-shaped decahedra achieved the highest mass activity (0.94 mA/μgPt) and area activity (1.09 mA/cm2Pt), which is ~6.7 and 5 times, respectively, as high as those of the commercial Pt/C (ETEK). Significantly, such star-shaped decahedra were highly stable with ~10% loss in area activity and ~20% loss in mass activity after 30,000 CV cycles in O2 saturated acid solution.

    ABSTRACT: Laparoscopic surgery has been shown to offer more advantages than open surgery for the treatment of gastric cancer. However, the perioperative immune responses after laparoscopic surgery remain largely unexplored. Here, we analyzed the immunity of gastric cancer patients treated by laparoscopy-assisted gastrectomy (LAG) or open gastrectomy (OG) with D2 dissection. Seventy patients were randomized into LAG and OG groups. The operative details and postoperative outcomes of the two groups were compared. The immune factors were measured preoperatively as well as on the first, third, and seventh postoperative days (POD). Our results indicate that there was no significant difference between two groups in clinical characteristics. The profiles of white blood cells, neutrophils, lymphocytes, as well as the lymphocyte subpopulations, including T lymphocytes, B lymphocytes, CD4+ T cells, and CD8+ T cells were similar in the LAG and the OG groups. Only the natural killer cell counts were significantly higher in LAG-treated patients than in OG-treated ones on POD7. Moreover, no statistical differences were found between the two groups with respect to the levels of perioperative cytokines, including IFN-γ, IL-4, IL-6, and TNF-α. However, compared with the OG group, most of the immune factors in the LAG group had trends to return to preoperative levels on POD7. Our study demonstrates that the immune function of LAG-treated patients showed patterns similar to that of OG-treated patients, although larger prospective multicenter trials are needed to further evaluate the immunological status of LAG.

    ABSTRACT: Coxsackievirus A8 (CV-A8), a member of the genus Enterovirus of the family Picornaviridae, can cause a variety of infectious diseases, such as hand, foot and mouth disease (HFMD), herpangina (HA), encephalitis, paralysis, myelitis, and meningitis. This is a first report of complete genome sequences of CV-A8 strains associated with HFMD/HA since the prototype strain Donovan was identified in 1949. The complete genome sequences of eight new CV-A8 strains showed 19.2 %-20.6 % nucleotide differences when compared to the prototype strain Donovan, and 81.5 %-99.9 % similarity to each other. The topology of a polyphyletic tree based on complete capsid protein gene sequences indicated that the new CV-A8 strains and Donovan are monophyletic. However, seven CV-A8 strains clustered with CV-A10 and CV-A2 in the 5'UTR and P2 region, respectively. In the P3 region, three and four CV-A8 strains grouped with CV-A6 and CV-A2, respectively. Seven CV-A8 strains segregated from Donovan and grouped in a separate lineage in the 3'UTR. The strain CVA8/SZ266/CHN/2014 was most similar to EV71 in the nonstructural proteins regions. Phylogenetic analysis classified worldwide CV-A8 isolates into four distinct clusters, and almost all Chinese and Thai CV-A8 strains evolved independently in their respective lineages, which indicated geographical evolution of CV-A8.

    ABSTRACT: Purpose: Many studies revealed that the recurrence rate of stage II colon cancer was up to 25-40 %. Regrettably, the risk factors for recurrence of stage II colon cancer remain ambiguous. So, we conducted this study to identify the clinicopathological factors associated with prognosis of stage II colon cancer. Methods: We enrolled 452 stage II colon cancer patients who underwent radical resection at Peking University Cancer Hospital between January 2007 and December 2010, and 162 patients who received adjuvant treatment were excluded. Results: The 5-year recurrence rate and overall survival of this cohort were 19.3 (56/290) and 75.9 % (220/290), respectively. In univariate analysis, the following variables were significantly associated with tumor recurrence: male patients (P < 0.001), tumor size >5 cm(P = 0.048), and preoperative carcinoembryonic antigen (CEA) level ≥5 ng/ml (P = 0.004); the following factors were significantly associated with adverse 5-year overall survival: male patients (P < 0.001), age ≥60 years old (P = 0.004), less than 12 lymph nodes (P = 0.006), and preoperative CEA level ≥5 ng/ml (P = 0.011). In multivariate analysis, the preoperative CEA level ≥5 ng/ml (P = 0.003) and male (P < 0.001) were adverse variables significantly associated with tumor recurrence, and the preoperative CEA level ≥5 ng/ml (P = 0.016), male (P < 0.001), and age ≥60 years old (P = 0.008) were independent prognostic factors for the 5-year overall survival rate, respectively. Conclusions: The preoperative CEA level ≥5 ng/ml and male were undesirable factors significantly associated with tumor recurrence. The preoperative CEA level ≥5 ng/ml, male, and age ≥60 years old were adverse factors significantly associated with poor prognosis.

    ABSTRACT: Dynamics of thermally induced composition redistribution of sandwich-like Pt-Ni octahedral electrocatalysts was studied in situ using a variable-temperature environmental transmission electron microscope (ETEM). Dislocations were observed and on heating treatment moved toward the surface over time, resulting in an alloy nanoparticle with significant increase Ni content on the surface, which was confirmed by X-ray photoelectron spectroscopy. The thermally treated Pt-Ni octahedral catalysts showed significant improvement in catalyzing oxygen reduction reaction over the as-made nanoparticles, reaching values of 1.4 A/mgPt in mass activity and 4.8 mA/ in area specific activity. Our study shows the important effect of postsynthesis treatment on the optimization of Pt and Ni atomic distribution, thus the catalytic activity and stability; and the power of in situ ETEM in understanding the structural origin of enhanced catalytic performance with atomic level of details. © 2015 American Institute of Chemical Engineers AIChE J, 2015

    ABSTRACT: A new surface molecularly imprinted polymer (MIP) based on nano-TiO2 was developed using propazine (Pro) as a template molecule, ethyleneglycol dimethacrylate (EGDMA) as a crosslinker, methacrylic acid (MAA) as a functional monomer, and 2,2'-azobis (isobutyronitrile) (AIBN) as an initiator. Structures of the newly synthesized surface MIPs were characterized by Fourier transmission infrared spectrometry (FT-IR), scanning electron microscope (SEM), transmission electron microscope (TEM), and X-ray diffraction (XRD). The MIP had a good adsorption capacity and high recognition selectivity to propazine. Meanwhile, it exhibited a cross-selectivity for simazine (Sim) and atrazine (Atr). The MIPs were used as a solid phase extraction (SPE) material. Concomitant extraction, purification, and determination of three pesticides (Pro, Sim, and Atr) residues in water, soil, and maize plant and grain samples were performed by MIP-SPE coupled with high performance liquid chromatography (HPLC). The highly selective separation and enrichment of Pro, Atr, and Sim from the complex environmental media can be achieved. Thus, the newly developed technique provides an analytical platform to quantify the trace amount of Pro, Sim, and Atr residues in multi environmental media and food source.

    ABSTRACT: Objective: To investigate the predictive value of preoperative detection of CEA and CA199 for prognosis in patients with stage II(-III( colorectal cancer (CRC). Methods: Clinicopathological and follow-up data of 266 patients with stage II(-III( colorectal cancer confirmed by pathology and undergoing radical resection in our department from 2004 to 2006 were retrospectively analyzed. The 5-year overall survival (OS) and disease-free survival (DFS) between normal CEA patients and increased CEA ones, and normal CA199 patients and increased CA199 ones were compared respectively. Moreover, the risk factors of OS and DFS were examined. Results: Among these 266 patients, 119 (44.7%) had preoperative elevated CEA, and 74(27.8%) had increased CA199. The median follow-up time was 63 months. Kaplan-Meier survival curves indicated that patients with elevated preoperative CEA had worse 5-year OS (54.6% vs. 72.8%, P=0.001) and DFS (75.2% vs. 83.3%, P=0.042) than those with normal CEA respectively. Meanwhile, patients with elevated CA199 had worse OS (45.9% vs. 71.9%, P=0.000) and DFS (74.2% vs. 81.8%, P=0.047) than those with normal CA199 respectively. Multivariate analysis revealed that male (HR=3.016, 95% CI: 1.536-5.919, P=0.001), lymph node metastasis (HR=2.278, 95% CI: 1.272-4.081, P=0.006), and preoperative elevated CEA (HR=1.794, 95%CI: 1.022-3.149, P=0.042) were independent prognostic factors of DFS. While vascular thrombosis(HR=2.041, 95% CI: 1.294-3.221, P=0.002), lymph node metastasis (HR=2.480, 95% CI:1.548-3.972, P=0.000), and preoperative elevated CA199 (HR=2.145, 95% CI:1.414-3.254, P=0.000) were independent prognostic factors of OS in patients with stage II(-III( CRC. Conclusion: Combined detection of preoperative CEA and CA199 can be used in evaluating the prognosis of patients with stage II(-III( CRC.

    ABSTRACT: Laparoscopic surgery is an acceptable alternative to open surgery in colorectal cancer treatment. However, in gastric cancer, there is not much scientific evidence. Here, we proposed a prospective randomized clinical trial to evaluate the radicalness and safety of laparoscopic D2 dissection for gastric cancer. From October 2010 to September 2012, 300 patients with gastric cancer were randomized to undergo either laparoscopy-assisted gastrectomy (LAG) or conventional open gastrectomy (OG) with D2 dissection. Clinicopathological parameters, recovery and complications were compared between these two groups. Thirty cases were excluded because of refusing to be involved in the trial, having peritoneal seeding metastasis or LAG conversed to OG, and finally 270 cases were analyzed (128 in LAG and 142 in OG). No significant differences were observed in gender, age, body mass index, stages and types of radical resection [radical proximal gastrectomy (PG + D2), radical distal gastrectomy (DG + D2) and radical total gastrectomy (TG + D2)] (P > 0.05). The number of harvested lymph nodes (HLNs) was similar (29.3 ± 11.8 in LAG vs. 30.1 ± 11.4 in OG, P = 0.574). And in the same type of radical resection, no significant difference was found in the number of HLNs between the two groups (PG + D2, P = 0.770; DG + D2, P = 0.500; TG + D2, P = 0.993). The morbidity of the LAG group (21.8 %) was also comparable to the OG group (19.0 %, P = 0.560). However, the LAG group had significantly less blood loss and faster recovery, and a longer operation time (P < 0.05). Laparoscopic D2 dissection is feasible, safe and capable of fulfilling oncologic criteria for the treatment of gastric cancer.

    ABSTRACT: To assess the accuracy of POSSUM scoring system in predicting surgical risk in patients with gastric cancer, and provide a feasible reference to clinical decision. Clinical data of 310 patients suffered from gastric cancer were analyzed retrospectively, including 278 cases in laparoscopic group and 32 cases in open group, between April 2009 and April 2014 in the department of minimally invasive gastrointestinal surgery, Peking University Cancer Hospital. Preoperative physiology score(PS), operative score(OS) and predictive morbidity rate(R1) were calculated according to POSSUM scoring system, which were used to assess the accuracy of R1 in open group. Two different scoring systems (R1traditional and R1modified according to adjustment of operative excision area) were applied in the laparoscopic group, and were compared for predicting the accuracy of R1 in the laparoscopic group. Besides, postoperative morbidities were compared between the two groups of patients with different preoperative physiological status(low risk group: PS≤20, high risk group: PS≥21). The predictive accuracy for open group patients were acceptable, and the ratio of expected and observed(E/O) was 1.2. In the laparoscopic group, the R1modified was 29.1%, and observed morbidity was 23.4% with an E/O of 1.2. The R1modified was more accurate than R1traditional(38.5%, E/O traditional was 1.6). Both modified and traditional POSSUM scoring system predicted well in low risk patients in the laparoscopic and open group, and E/O was 1.0. However, it overestimated morbidities in median and high risk patients for both laparoscopic and open group. E/O was 1.6, and 1.9 in laparoscopic group, as well as 1.2 and 1.3 in open group. For patients in poor preoperative physiological status(PS≥21), the morbidity in laparoscopic group was lower than that in open group(27.3% vs. 5/7, P=0.020). Modified POSSUM scoring system predicted morbidity more accurately in the laparoscopic group than traditional system. As for patients in poor preoperative physiological status, laparoscopic assisted gastrectomy procedure might reduce postoperative morbidities.

    ABSTRACT: An ultrafast and low-power all-optical tunable metamaterial-induced transparency is realized, using polycrystalline barium titanate doped gold nanoparticles and multilayer tungsten disulfide microsheets as nonlinear optical materials. Large nonlinearity enhancement is obtained associated with quantum confinement effect, local-field effect, and reinforced interaction between light and multilayer tungsten disulfide. Low threshold pump intensity of 20 MW/cm2 is achieved. An ultrafast response time of 85 ps is maintained because of fast carrier relaxation dynamics in nanoscale crystal grains of polycrystalline barium titanate. This may be useful for the study of integrated photonic devices based on two-dimensional materials.

    ABSTRACT: Stable sub-two nanometer AgAu nanowires were synthesized using a CO-mediated gas reducing agent in liquid solution (GRAILS) method. These AgAu nanowires are stable, and do not readily break into short nanorods upon heating or electron beam irradiation. The surfaces along the longitudinal direction of the AgAu nanowires were largely bounded by the stable {111} facets. This structure differs from those ultrathin Au nanowires made without the use of CO gas, which were bounded by the {100} facets and unstable under e-beam irradiation. These differences in structure and composition lead to enhanced stability.

    ABSTRACT: Heat released from the exothermic reaction between amine Heat released from the exothermic reaction between amine (R-NH2) and carboxylic acid (R'-COOH) was systematically utilized to prepare noble metal nanocrystals (NCs) of various shapes in the presence of carbon monoxide (CO). The heating profile of the solution mixtures was controllable by adjusting both the type and ratio of these two kinds of molecules. A maximum heating rate of 20°C/s was achieved. Uniform gold nanowires and nanoparticles were produced by tuning the molar ratio between carboxylic acid and oleylamine (OAm). In addition, concave tetrahedral palladium nanocrystals were also produced. This self-heating method is highly versatile for making a variety of metal nanostructures. It represents a new, potentially scalable and extremely fast production route of metal nanostructures. This novel production route arises from the unique manner in which homogeneous heat releases from ligand-based chemical reactions.

    ABSTRACT: Flexible, charged Pd nanosheets were prepared by using short chain thiolated carboxylic acids and amines. They could wrap around amine or hydroxyl functionalized micron-sized spheres driven by electrostatic interactions. When incubation with HepG2 cells, positively charged cysteamine (CA) functionalized Pd nanosheets exhibited a much higher cytotoxicity, showing more than 80% cell death at 100 ppm than the negatively charged 3-mecaptopropionic acid (MPA) functionalized ones which caused 30% of the cell death. The results show through surface functionalization, Pd nanosheets can be modified to interact differently with HepG2 cancerous cells, resulting in varied cytotoxicity.

    ABSTRACT: Malathion is an organophosphorous insecticide for controlling insects on fruits and vegetables, miscellaneous household insects, and animal parasites. It is important to develop highly efficient and selective pre-treatment method for analyzing malathion residues in environment and samples from agricultural products based on the molecularly imprinted polymers (MIPs). In this study, we developed a tailor-made MIP method with highly specific recognization to the template. The MIPs were prepared using malathion as a template, methacrylic acid (MAA) as a functional monomer, ethylene glycol dimethacrylate (EGDMA) as a crosslinker, azodiisobutyronitrile (AIBN) as an initiator, and the acetonitrile-chloroform (1:1, v/v) as a porogen. The molecular recognization mechanism of malathion and MAA was evaluated by molecular simulation, ultraviolet spectrometry (UV), and (1)H-nuclear magnetic resonance ((1)H-NMR). MAA interacted specifically with malathion by hydrogen bond with a ratio of 2:1. The MIPs exhibit a high affinity, recognition specificity, and efficient adsorption performance for malathion. The Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), surface area and porosimeter analyzer, thermogravimetric/differential thermal analyzer (TG/DTA) were used to characterize the properties of MIP. The malathion residues in soil, tap water, and cabbage were cleaned up by MIP-SPE, detected quantitatively using GC-FPD, and confirmed by GC-MS/MS. The limits of tap water, soil, and cabbage were confined to 0.001 mg L(-1), 0.004 and 0.004 mg kg(-1), respectively. The spiked recoveries of malathion were 96.06-111.49 % (with RSD being 5.7-9.2 %), 98.13-103.83 % (RSD, 3.5-8.7 %), and 84.94-93.69 % (RSD, 4.7-5.8 %) for tap water, soil, and cabbage samples, respectively. Thus, the method developed here can be used effectively in assessing malathion residues in multiple environmental samples. The aim of the study was to provide an efficient, selective, and accurate method for analyzing malathion at trace levels in multiple media.
