| 1 | Epidemiology of gastroesophageal reflux disease:A general population-based study in Xi'an of Northwest China显示文摘AIM: Gastroesophageal reflux disease (GERD) is a common disorder in the Western population, but detailed population-based data in China are limited. The aim of this study was to understand the epidemiology of symptomatic gastroesophageal reflux (SGER) in adults of Xi'an, a northwestern city of China, and to explore the potential risk factors of GERD. METHODS: Symptoms suggestive of GERD, functional dyspepsia (FD), irritable bowel syndrome (IBS), upper respiratory diseases and some potential risk factors were investigated in a face-to-face manner in a region-stratified random samples of 2 789 residents aged 18-70 years in Xi'an by using a standardized questionnaire. METHODS: With a response rate of 91.8%, the prevalence of SGER was 16.98% (95% CI, 14.2-18.92) in Xi'an adults, and no gender-related difference was observed (P<0.05). SGER was more common among subjects aged 30-70 years than in those aged 18-29 years (P<0.01). The prevalence of SGER in rural, urban and suburban subjects was 21.07%, 17.44% and 12.12%, respectively, and there was a significant difference between rural, urban and suburban regions (P<0.05). Compared with subjects without SGER, the prevalence of symptoms suggestive of FD and IBS, pneumonia, asthma, bronchitis, laryngitis, pharyngitis, chronic cough, wheeze, globus sensation, oral ulcer and snore was significantly increased in subjects with SGER (P<0.01). Heavy smoking (OR=5.76; CI, 3.70-6.67), heavy alcohol use (OR=2.85; CI, 1.67-4.49), peplJc ulcer (OR=5.76; CI, 3.99-8.32), cerebral palsy (OR=3.97; CI, 1.97-8.00), abdominal operation (OR=2.69; CI, 1.75-4.13), obesity(OR=2.16; CI, 1.47-3.16), excessive food intake (OR= 1.43;CI, 1.17-1.15), sweet food (OR=1.23; CI, 0.89-1.54), and consumption of coffee (OR= 1.23; CI, 0.17-2.00) were independently associated with SGER. The episodes of GERD were commonly precipitated by dietary factors (66.05%), followed by body posture (26.54%), ill temper (23.72%), fatigue (22.32%) and stress (10.93%). CONCLUSION: GERD is common in Xi'an's adult population with a mild or moderate degree. The etiology and pathogenesis of GERD are probably associated with FD, IBS, and some respiratory, laryngopharyngeal and odontostological diseases or symptoms. Some lifestyles, diseases and dietary factors are the risk factors of GERD. | Jin-HaiWang Jin-YanLuo LeiDong JunGong MingTong | 2004 | World Journal of Gastroenterology2004，10，11： | 48 |
| 2 | An Ethylene-inhibited NF-YC Transcription Factor RhNF-YC9 Regulates Petal Expansion in Rose显示文摘The speed of flower opening is closely related to their ornamental period.Ethylene functions as a negative regulator involved in the regulation of the petal expansion process.In this study,we isolated a NF-YC transcription factor gene,RhNF-YC9,fromrose petals.RhNF-YC9 expression was induced at the early stages of flower opening but was inhibited by ethylene treatment.Silencing RhNF-YC9 decreased the speed of petal expansion from stage 2 to stage 5.The expressions of 11 cell expansion-related genes involved in cell wall loosening,cell turgor modulation,and cytoskeleton remodeling were significantly down-regulated in RhNF-YC9-silenced petals.We also found that silencing RhNF-YC9 decreased the expression of gibberellin acid(GA)biosynthetic gene RhGA20ox while significantly increasing the transcripts of GA catabolic gene RhGA2ox,reducing the accumulation of GA4 and GA7.The influence of ethylene treatment on the expression of RhGA20ox and RhGA2ox showed the same trend.These results together suggested that RhNF-YC9 positively regulated the speed of petal expansion and mediated the crosstalk between ethylene and GA.Our findings revealed a new insight into the function of NF-YC transcription factors involved in ethylene-regulated petal expansion. | Changxi Chen Nisar Hussain Yaru Wang Mingtong Li Lin Liu Meizhu Qin Nan Ma Junping Gao Xiaoming Sun | 2020 | Horticultural Plant Journal2020，6，6： | 9 |

| 12 | Development of an Omni-Directional Shear Horizontal Wave Transducer Based on a Radially Poled Piezoelec trie Ring显示文摘For the inspection of large plate-like structures,the omni-directional guided wave transducer-based system has been regarded as an effective tool since only a few transducers are required to cover the entire inspection area without blind zones.In comparison with Lamb waves,the shear horizontal(SH)wave is more promising because its fundamental mode is non-dispersive.In this work,we proposed an omni-directional SH wave piezoelec trie t ransducer(OSH-PT)based on a radially poled d24-mode PZT ring.Eoth the finite element simulations and experiments were carried out to demonstrate its performance in generating and receiving SH°wave.Results showed that the radially poled OSH-PT could generate single-mode SHo wave and receive SHo wave only over a wide frequency range from 70 to 200 kHz.The obtained signal-to-noise ratio can reach up to 26 dB in generation and 24 dB in reception.The omni-directivity of this OSH-PT is also very good with the deviation only about 6%in both generation and reception of SHo wave.Considering its easy fabrication,low cost and superior performances,this proposed OSH-PT may promote the applications of SHo wave-based inspection in structural health monitoring and nondestructive testing. | Qiang Huan Mingtong Chen Ai-Kah Soh Faxin Li | 2019 | Acta Mechanica Solida Sinica2019，32，1： | 0 |
| 13 | A unidirectional SH wave transducer based on phase-controlled antiparallel thickness-shear(d15)piezoelectric strips显示文摘In recent years,shear horizontal(SH)waves are being paid more and more attention to in structural health monitoring as it has only one displacement component.In this paper,a unidirectional SH wave transducer based on phase-controlled antiparallel thickness-shear(d15)piezoelectric strips(APS)is proposed.Here two pairs of identical APS were used each of which is a bidirectional SH wave transducer.By setting the interval between the two pairs of APS as 1/4 wavelength and the excitation delay between them as 1/4 period of the central operating frequency,unidirectional SH waves can be excited.Both finite element simulations and experiments were performed to validate the proposed design.Results show that SH0 waves were successfully excited only along one direction and those along the unwanted directions were suppressed very well.The proposed unidirectional SH wave transducer is very helpful to study the fundamentals and applications of SH waves. | Mingtong Chen Qiang Huan Faxin Li | 2020 | Theoretical & Applied Mechanics Letters2020，10，5： | 0 |
| 14 | Multi-scale analysis on last millennium climate variations in Greenland by its ice core oxygen isotope显示文摘The empirical mode decomposition method is used for analyzing the paleoclimate proxy δ18O from Greenland GISP2 ice core.The results show that millennium climate change trends in Greenland record the Medieval Warm Period (MWP) from 860AD-1350AD lasting for about 490 years,and the Little Ice Age (LIA) from 1350AD-1920AD lasting about 570 years.During these events,sub cooling-warming variations occurred.Its multi-scale oscillations changed with quasi-period of 3-year,6.5-year,12-year,24-year,49-year,96-year,213-year and 468-year,and are not only affected by ENSO but also by solar activity.The oscillation of intrinsic mode function IMF7,IMF8 and their tendency obviously appear in 1350AD which is considered as the key stage of transformation between MWP and LIA.The results give more detailed changes and their stages of millennium climate change in high latitude areas of the Northern Hemisphere. | MingTong Yu ZhenShan Lin JianLi Du ZhenZhen Zhang | 2010 | Research in Cold and Arid Regions2010，2，2： | 0 |
| 15 | Association of β-fibrinogen gene-148C/T and-455G/A polymorphisms and coronary artery disease in Chinese population:A Meta analysis显示文摘The purpose of our study was to evaluate the correlation between the β-fibrinogen gene –148C/T and –455G/A polymorphisms and susceptibility to coronary artery disease in the Chinese population using a meta–analytic approach. Eligible studies about this correlation were identified by searching the PubMed, EMBASE, and CNKI databases. Of the 13 identified, 7 (with 1488 cases and 1234 controls) involved the –148C/T polymorphism and 9 (with 1023 cases and 1081 controls) involved the –455G/A polymorphism. No publication bias was detectable and heterogeneity testing found significant differ-ences between the ORs for both groups of studies. The combined OR for the 7 studies on susceptibility to coronary artery disease in –148T allele carriers compared to the –148C/C wild-type homozygotes was 1.31 (95%CI: 0.94-1.84, P=0.11). The combined OR for the 9 studies on susceptibility to coronary artery disease in –455A allele carriers compared to the –455G/G wild-type homozygotes was 1.75 (95%CI: 1.24-2.46, P=0.001). Our results suggest the absence of an association between the β-fibrinogen gene –148C/T polymorphism and susceptibility to coronary artery disease and the possibility that –455G/A polymorphism (in particular, allele A) increases susceptibility to this disease in the Chinese population. | CHEN XiaoChao XU MingTong JIN LiZi CHEN Jian CHEN WeiQing | 2008 | Science China(Life Sciences)2008，51，9： | 0 |
