Tree peony is a traditional famous flower of China, and plays an important role in Chinese traditional culture. But the floral scent of tree peony in vivo is little known. In this study, in order to explore the floral composition of tree peony, floral volatiles of six cultivars, including Paeonia suffruticosa 'Zhaofen' (ZF), P. suffruticosa 'Luoyanghong' (LYH), P. ostii 'Fengdanbai' (FDB), P. ${\times}$ lemonei 'High noon' (HN), P. ${\times}$ lemonei 'Renown' (R), and P. rockii 'Gaoyuanshenghuo' (GYSH) were collected by dynamic headspace and then identified by Automated Thermal Desorption-Gas Chromatography/Mass Spectometry. The results showed that floral fragrances of the six cultivars were qualitatively and quantitatively distinct. A total of 105 volatiles involving ten categories were detected. But not all volatile categories were emitted from these cultivars. The six peony cultivars emitted some shared compounds and peculiar compounds. The total released amounts of volatiles emitted from six cultivars were found significantly different, which was greatest for 'GYSH'. The most abundant volatile compounds detected from 'ZF', 'LYH', 'FDB', 'HN', 'R', and 'GYSH' were respectively ${\alpha}$-pinene, 2,3-dihydroxy propanal, 3-methyl-1-butanol, 2-ethyl-1-hexanol, acetic acid 1-methylethyl ester, and 5-ethyl-2,2,3-trimethyl heptane. This result may contribute to exploring the biosynthesis and emission mechanism of floral scent in tree peony.

Zhao, Fang-Hui,Tiggelaar, Sarah M.,Hu, Shang-Ying,Zhao, Na,Hong, Ying,Niyazi, Mayinuer,Gao, Xiao-Hong,Ju, Li-Rong,Zhang, Li-Qin,Feng, Xiang-Xian,Duan, Xian-Zhi,Song, Xiu-Ling,Wang, Jing,Yang, Yun,Li, Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.5

Objectives: To assess knowledge of HPV and attitudes towards HPV vaccination among the general female population, government officials, and healthcare providers in China to assist the development of an effective national HPV vaccination program. Methods: A cross-sectional epidemiologic survey was conducted across 21 urban and rural sites in China using a short questionnaire. 763 government officials, 760 healthcare providers, and 11,681 women aged 15-59 years were included in the final analysis. Data were analyzed using standard descriptive statistics and logistic regression. Results: Knowledge of HPV among the general female population was low; only 24% had heard of HPV. Less than 20% of healthcare providers recognized sexually na$\ddot{i}$ve women as the most appropriate population for HPV vaccination. There was high acceptance of the HPV vaccine for all categories of respondents. Only 6% of women were willing to pay more than US $300 for the vaccine. Conclusions: Aggressive education is necessary to increase knowledge of HPV and its vaccine. Further proof of vaccine safety and efficacy and government subsidies combined with increased awareness could facilitate development and implementation of HPV vaccination in China.

Genotoxicity and effect on early stage proliferation of osteoprogenitor cells of titanium surfaces modified by heptylamine functionalization through Plasma Enhanced Chemical Vapor Deposition (PECVD) were evaluated in current study. Mouse embryo osteoprogenitor MC3T3-E1 cells were grown on titanium surfaces of all the groups. The CCK-8 assay showed the growths of MC3T3-E1 cells on treated titanium disks were not inhibited compared with those on pure titanium groups. Result of Single Cell Gel Electrophoresis (SCGE) test indicated the treated groups showed no significant differences in tail length, tail DNA%, and tail moment compared with pure titanium group. Rate of micronucleus, nucleoplamic buds and nuclear blebs showed no significant differences between treated groups and pure titanium group. Our research exhibited that: The amino-group functionalized titanium surface has neither genotoxicity nor detrimental effects on early-stage proliferation towards osteoprogenitor cells in vitro, thus offer a theoretic support for the clinical use of such functionalized titanium as implant surface.

Purpose: This study aimed to investigate the prevalence, risk factors, and effects of primary nocturnal enuresis (PNE) on physical and mental health in young adults in mainland China. Methods: An anonymous questionnaire was used to collect information including the sociodemographic characteristics, history of PNE, family history, daytime voiding symptoms, Pittsburgh Sleep Quality Index (PSQI) scores, Self-Esteem Scale (SES), and Self-Rating Depression Scale (SDS). A total of 22,500 university students from 23 provinces and 368 cities in mainland China were included. Results: In total, 21,082 questionnaires were collected, and 20,345 of them qualified for statistical analysis. The PNE prevalence was 1.17%, and the distribution of monosymptomatic nocturnal enuresis (MNE) and nonmonosymptomatic nocturnal enuresis (NMNE) was 66.1% and 33.9%, respectively. In total, 28% of respondents with PNE reported bedwetting daily, 31.6% between 1 and 7 times weekly, and 40.4% between 1 and 4 times monthly; 80% of PNE cases had no history of treatment. The prevalence of PNE in patients with a family history, frequency, urgency, urinary incontinence, and recurrent urinary tract infections was significantly higher than in those without these conditions (P<0.001). PNE was significantly correlated with the PSQI total score (sleep quality) (P=0.011). The SES score was lower and the SDS was higher (P<0.001) in the PNE group than in those without PNE. Conclusions: In mainland China, the PNE prevalence among young adults was found to be high, and PNE had significant effects on physical and mental health. Risk factors included a family history, daytime voiding symptoms, and lack of treatment.

Hui Lu,Binghui Zeng,Dongsheng Yu,Xiangyi Jing,Bin Hu,Wei Zhao,Yiming Wang 대한영상치의학회 2015 Imaging Science in Dentistry Vol.45 No.3

Cleidocranial dysplasia (CCD) is a rare congenital disorder, typically characterized by persistently open skull sutures, aplastic or hypoplastic clavicles, and supernumerary teeth. Mutations in the gene encoding the runt-related transcription factor 2 (RUNX2) protein are responsible for approximately two thirds of CCD patients. We report a 20-year-old CCD patient presenting not only with typical skeletal changes, but also complex dental anomalies. A previously undiagnosed odontoma, 14 supernumerary teeth, a cystic lesion, and previously unreported fused primary teeth were discovered on cone-beam computed tomography (CBCT) scans. Mutation analysis identified the causal c.578G>A (p.R193Q) mutation in the RUNX2 gene. At 20 years of age, the patient had already missed the optimal period for dental intervention. This report describes the complex dental anomalies in a belatedly diagnosed CCD patient, and emphasizes the significance of CBCT assessment for the detection of dental anomalies and the importance of early treatment to achieve good outcomes.

C60 is widely investigated because of its unique structure. But its applications in solid propellant seem to be relatively neglected. C60 has more outstanding features than carbon black which is widely used as a catalyst ingredient of solid propellant. To combine the advantages of fullerene and lead salts, another good composite in propellant catalysts, we synthesized a kind of fullerene phenylalanine lead salt (FPL) and explored its thermal performances by differential thermal analysis (DTA) and thermogravimetry analysis (TGA). The results show it undergoes four exothermic processes started from 408 K. Combined TGA and X-ray diffractometer (XRD), the decomposition mechanism of FPL was derived by TG-IR and comparing IR spectra of FPL and its residues after burned to 327 °C, 376 °C and 424 °C, respectively. Effect of FPL on the decomposition characteristic of hexogen (RDX), a type of explosive in propellant, has been investigated using DTA at different heating rate, which shows the decomposition temperatures of the explosive are all reduced by more than 20 K. The corresponding activation energy (Ea) is decreased by 30 kJ·mol−1. So FPL has potential application as a combustion catalyst in solid propellant.

Generation of low-order reservoir models using Krylov-enhanced proper orthogonal decomposition method

Jing Cao,Hui Zhao,Gaoming Yu 한국자원공학회 2016 Geosystem engineering Vol.19 No.6

Reservoir simulation of realistic reservoir can be computationally demanding because of the large number of system unknowns. Model order reduction (MOR) technique represents a promising approach for accelerating the simulations. In this work, we focus on the application of a MOR technique called Krylov-enhanced proper orthogonal decomposition (KPOD), which combines the moment-matching property of Arnoldi with data generalization ability of proper orthogonal decomposition (POD) to alleviate POD’s dependence on the choice of snapshots and the particular input conditions. We apply KPOD and POD methods for a two-phase (oil–water) reservoir model which is solved by semi-implicit Euler discretization and consider two different scenarios to evaluate the predictive capability of POD and KPOD methods. The example demonstrates that even though the difference of inputs of testing and training process is larger, the results of KPOD are in close agreement with the full-order simulation, while the accuracy of POD becomes very poor. And because the number of base vector for KPOD is less, the KPOD is able to approximately reduce the simulation time by 3 times compared with the full-order reservoir model. The KPOD method outperforms POD method in computational efficiency and accuracy.

Isolation, Structural Characterization, and Lymphopoiesis Stimulant Activity of a Polysaccharide from the Abalone Gonad

Jing-Feng Yang,Yue-hui Li,Jun Zhao,Peng-fei Li,Ce Zhu,Ye-han Song,Lan-yi Zhang,Bei-Wei Zhu 한국식품과학회 2015 Food Science and Biotechnology Vol.24 No.1

A novel polysaccharide (AGP-32) from the gonad of Haliotis discus hannai Ino was isolated using a protease-assisted process and successive ion-exchange and gel-filtration chromatography. The backbone of AGP-32 was determined using hydrolysis with trifluoroacetic acid. FTIR, NMR, and methylation analysis, and periodate oxidation and Smith degradation analysis revealed that the AGP-32 backbone mainly consisted of (1→6)-linked mannose, (1→3)-linked galactose, and (1→3)-linked glucose in a proportion of 2:3:1. An in vitro cell assay indicated that AGP-32 promoted mice splenic lymphocyte proliferation by 26% at a concentration of 50 μg/mL. AGP-32 had an effect on immune protection and is a candidate for consideration as a functional food.
