| 1 | Ultrasonically activated scalpel versus monopolar electrocautery shovel in laparoscopic total mesorectal excision for rectal cancer显示文摘AIM: To investigate the feasibility and safety of monopolar electrocautery shovel (ES) in laparoscopic total mesorectal excision (TME) with anal sphincter preservation for rectal cancer in order to reduce the cost of the laparoscopic operation, and to compare ES with the ultrasonically activated scalpel (US). METHODS: Forty patients with rectal cancer, who underwent laparoscopic TME with anal sphincter preservation from June 2005 to June 2007, were randomly divided into ultrasonic scalpel group and monopolar ES group, prospectively. White blood cells (WBC) were measured before and after operation, operative time, blood loss, pelvic volume of drainage, time of anal exhaust, visual analogue scales (VAS) and surgery-related complications were recorded. RESULTS: All the operations were successful; no one was converted to open procedure. No significant differences were observed in terms of preoperative and postoperative d 1 and d 3 WBC counts (P = 0.493, P = 0.375, P = 0.559), operation time (P = 0.235), blood loss (P = 0.296), anal exhaust time (P = 0.431), pelvicdrainage volume and VAS in postoperative d 1 (P = 0.431, P = 0.426) and d 3 (P = 0.844, P = 0.617) between ES group and US group. The occurrence of surgery-related complications such as anastomotic leakage and wound infection was the same in the two groups. CONCLUSION: ES is a safe and feasible tool as same as US used in laparoscopic TME with anal sphincter preservation for rectal cancer on the basis of the skillful laparoscopic technique and the complete understanding of laparoscopic pelvic anatomy. Application of ES can not only reduce the operation costs but also benef it the popularization of laparoscopic operation for rectal cancer patients. | Bao-Jun Zhou, Wei-Qing Song, Qing-Hui Yan, Jian-Hui Cai, Feng-An Wang, Jin Liu, Guo-Jian Zhang, Guo-Qiang Duan, Zhan-Xue Zhang, Department of Gastrointestinal Surgery, The Second Hospital of Hebei Medical University, Shijiazhuang 050000, Hebei Province, China Author contributions: Zhou BJ, Song WQ, Yan QH, Cai JH, Wang FA, Liu J, Zhang GJ, Duan GQ and Zhang ZX contributed equally to this work Zhou BJ, Song WQ, Yan QH, Cai JH and Wang FA designed the research Zhou BJ, Liu J and Zhang GJ performed the research Duan GQ and Zhang ZX analyzed the data and Zhou BJ, Song WQ and Yan QH wrote the paper. | 2008 | World Journal of Gastroenterology2008，14，25： | 25 |
| 2 | Hydrogen peroxide-induced changes in intracellular pH of guard cells precede stomatal closure显示文摘Epidermal bioassay demonstrated that benzylamine, a membrane-permeable weak base, can mimick hydrogen peroxide (H2O2) to induce stomatal closure, and butyric acid, a membrane-permeable weak acid, can partly abolish the H2O2-induced stomatal closure. Confocal pH mapping with the probe 5-(and-6)- carboxy seminaphthorhodafluor- 1 - acetoxymethylester (SNARF-1-AM) revealed that H2O2 leads to rapid changes in cytoplasmic and vacuolar pH in guard cells of Viola faba L, i. e. alkalinization of cytoplasmic areas occur red in parallel with a decrease of the vacuolar pH, and that butyric acid pretreatment can abolish alkalinization of cytoplasmic areas and acidification of vacuolar areas of guard cells challenged with H2O2. These results imply that the alkalinization of cytoplasm via efflux of cytosol protons into the vacuole in guard cells challenged with H2O2 is important at an early stage in the signal cascade leading to stomatal closure. | ZHANG XIAO, FA CAI DONG, JUN FENG GAO, CHUN PENG SONG (Department of Biology, Henan University, Kaifeng 475001, China) (College of Life Sciences, Northwest Sci-Tech University of Agriculture and Forestry, Yangling 712100, China) | 2001 | Cell Research2001，11，1： | 24 |
| 3 | Report on Childhood Obesity in China (9): Sugar-sweetened Beverages Consumption and Obesity显示文摘Objective To explore the associations between sugar-sweetened beverage (SSB) consumption and obesity as well as obesity-related cardiometabolic disorders among children in China. Methods A total of 6974 (boys 3558, girls 3412) children aged 6-13 years participated in the study. Each participant's height, weight, waist circumference, fasting glucose, triglycerides, total cholesterol, high- density lipoprotein cholesterol, and low-density lipoprotein cholesterol were measured. The type of beverage consumption was determined using a self-administered questionnaire. Results SSBs were consumed regularly by 46.1% of the children. The prevalence [adjusted odds ratio (95% confidence internal (CI)] of obesity was 7.6% [as the reference group (ref.)], 10.1% [1.36(1.07, 1.74)], and 11.6% [1.46(1.21, 1.75)], among children who regularly drank milk, other beverages and SSBs, respectively. Regularly drinking SSBs elevated the likelihood of abdominal obesity [adjusted odds ratio (95% CI): 1.36 (1.17, 1.59)]. The prevalence [adjusted odds ratio (95% CI)] of obesity among children who regularly drank sports/caloric beverages, carbonated beverages, sweet tea, and plant protein beverages was 16.8% [2.00(1.31, 3.07)], 12.7% [1.52(1.23, 1.88)], 11.5% [1.52(1.18, 1.95)], and 10.4% [1.41(1.03, 1.94)], respectively, which was higher than that of regular milk drinkers [7.6 % (ref.)]. The prevalence [adjusted odds ratio (95% CI)] of abdominal obesity among children who regularly drank sweet tea, fruit/vegetable juices, and carbonated beverages was 17.7% [1.55(1.26, 1.90)], 16.2% [1.36(1.09, 1.70)], and 15.3% [1.24(1.03, 1.50)], respectively, which was much higher than that of regular milk drinkers [12.8% (ref.)]. Conclusions Regular SSB consumption was positively related to obesity and abdominal obesity. This relationship should be investigated further using a longitudinal study design. | SHANG Xian Wen LIU Ai Ling ZHANG Qian HU Xiao Qi DU Song Ming MA Jun XU Gui Fa LI Ying GUO Hong Wei DU Lin LI Ting Yu MA Guan Sheng | 2012 | Biomedical and Environmental Sciences2012，25，2： | 23 |
| 4 | Report on Childhood Obesity in China (10): Association of Sleep Duration with Obesity显示文摘Objectives To explore the association of sleep duration with obesity among children in urban areas of China.Methods A total of 6 576 children(3 293 boys and 3 283 girls) aged 7-11 years were randomly selected from 36 primary schools in 6 metropolitan cities in China.A 7-day Physical Activity Recall was used to assess the sleep duration and physical activity level.The height,weight,waist circumference(WC) and percentage of body fat(%BF,as determined by bioelectrical impedance analysis technique) were measured by following the standardized operation procedures.The information on demography,lifestyle and eating habits was collected with a self-administered questionnaire from participants and their parents.Results The average sleep duration per night in the children was 9.7 h with the decreasing trends along with the increase of age(P<0.05).The sleep duration was negatively associated with body mass index(BMI) and WC in both boys and girls after adjustment for confounders(β value-0.23 and-0.82 for boys,-0.24 and-0.91 for girls,respectively,P<0.01).However,no significant association of sleep duration with %BF was found.Children who slept less than 9.0 h per night had a higher risk for overweight and obesity(OR=1.29,95% CI:1.01,1.64) and abdominal obesity(OR=1.38,95% CI:1.04,1.83) as compared with those who slept for 10.0-10.9 h.Conclusions Short sleep duration is associated with obesity.It is important to ensure adequate sleep duration of children and foster their healthy lifestyle at an early stage of life. | MENG Li Ping LIUAi Ling HU Xiao Qi ZHANG Qian DU Song Ming FANG Hong Yun MA Jun XU Gui Fa LI Ying GUO Hong Wei DU Lin MA Guan Sheng | 2012 | Biomedical and Environmental Sciences2012，25，2： | 16 |
| 5 | Atmospheric particulate pollution of Lanzhou using magnetic measurements显示文摘To differentiate between natural and anthropogenic particulate sources in the atmosphere in Lanzhou City, samples were collected in different sites. The dust flux was calculated and magnetic measurements were conducted. Results show a distinct pattern of variation of dust flux within a year and it agrees with the shifts of atmospheric circulation regime. The magnetic parameters indicate that natural sources are the major components of atmospheric particulate during late spring and early summer, while anthropogenic sources contribute much more during winter months. The data also support the earlier findings that magnetic parameters are effective for differentiating between particulate arising from natural sources such as soil erosion and from anthropogenic sources such as coal combustion. | Chen Fa\|hu, Yang Li\|ping, Wang Jian\|min, Zhang Jia\|wu Institute of Environment & Hazards, Lanzhou University, Lanzhou 730000, China.

| 9 | Influence of Inclusion on Crack Initiation in Wheel Rim显示文摘Speed increase and heavy haul of the railway freight car are the effective measures to raise the transport ability of railway,and they have been the new trend for railway freight car development.The increase of speed and axle load will lead to the increase of wheel-rail contact stress,which will make a great change of stress distribution in the whole wheel rim.Goodier equation was employed to analyze the stress state around inclusion and cavity.In the operation of wheel-rail contact stress,stress concentration occurred in the pole of Al2O3 spherical inclusion,while it appeared on the equator of cavity.The critical inclusion sizes of 250 kN axle load freight car wheel at different velocities,a certain distance away from the tread,were calculated by Murakami equation.Comparing the inclusion in cast steel wheel with that in rolled steel wheel,it is found that the inclusion in cast steel wheel has much more excellent crack resistance than that in rolled steel wheel.In the meantime,in order to reduce the probability of rim crack,some suggestions were put forward. | MI Guo fa NAN Hong yan LIU Yan-lei ZHANG Bin ZHANG Hong SONG Guo xiang | 2011 | Journal of Iron and Steel Research(International)2011，18，1： | 8 |
| 10 | Alterations to biological soil crusts with alpine meadow retrogressive succession affect seeds germination of three plant species显示文摘Biological soil crusts(BSCs) are the important components of alpine meadow ecosystems.The extent and morphology of BSCs vary greatly with alpine meadow retrogressive succession due to grazing pressure.There is significant interest in impacts of crust composition on plant seed germination,especial l y in(semi-) arid environments.However,little is known about the influences of BSCs,and their associations with alpine meadow succession,on germination of typical alpine meadow vascular plant species.In a full factorial common-gardenexperiment,we studied effects of:(1) crust type,(2) seed position,and(3) surface texture on seed germination.We chose three typical alpine meadow plant species(i.e.Poa pratensis,Tibetia himalaica and Potentillen nivea),which belonged to different functional groups(graminoids,legumes,and forbs) and play important roles in all alpine meadow succession stages.Crust type and seed position influenced seed germination,and the inhibitory effects of BSCs depended on the crust type and seed species tested.The major factors influencing seed germination were BSC type,seed position,soil texture,and the interactions between BSC type and seed position; species and seed position; species andsurface texture; and species,crust type,and surface texture.Cyanobacteria crust significantly inhibited germination of all seeds.Seed position also had a significant effect on seed germination(p < 0.001).Fewer seedlings germinated on the surface than below the surface,this was especially true for P.nivea.seeds within cyanobacteria and lichen crusts.Only germination rates of T.himalaica on the soil surface were significantly correlated with plant occurrence frequency within the alpine meadow community.The poor correlation for the other two species is possibly that they are perennials.Our results clearly demonstrated that BSCs can be biological filters during seed germination,depending on the BSC succession stage.Through their influences on seed germination,BSCs can strongly influence community assemblages throughout alpine meadow retrogressive succession. | LI Yi-kang OUYANG Jing-zheng LIN Li XU Xing-liang ZHANG Fa-wei DU Yan-gong LIU Shu-li CAO Guang-min HAN Fa | 2016 | Journal of Mountain Science2016，13，11： | 7 |
| 11 | MiRNA-206 inhibits hepatocellular carcinoma cell proliferation and migration but promotes apoptosis by modulating cMET expression显示文摘A close relationship between cancer progression and microRNAs(miRNAs)regulation has been demonstrated.Abnormal microRNA-206(miR-206)expression has been shown to be related to the development of malignancies.However,the role of miR-206 in hepatocellular carcinoma(HCC)remains unclear.Here,we evaluated the function of miR-206 in HCC.Results showed that miR-206 expression was decreased in 27 human HCC tissues compared with that of adjacent normal tissues.Conversely,cMET was up-regulated in human HCC cancer tissues,and cMET levels were shown to be negatively correlated with miR-206 expression.Abnormally increased miR-206 expression in three HCC cell lines(SMMC-7721,HepG2,and Huh7)attenuated cell viability,migration,and invasion.Increased apoptosis was also observed in these miR-206 expressing cells.Furthermore,we identified that miR-206 targets the 3′-UTR of the cMET gene for silencing,and restoration of cMET expression reversed the inhibitory effect of miR-206 on HCC.Tumor cells expressing miR-206 also showed delayed growth in the in vivo experiments compared with the controls.Altogether,our findings provide new insights into the molecular mechanisms of HCC oncogenesis. | Yuanxi Wang Qinwen Tai Jinhui Zhang Junsheng Kang Feng Gao Feng Zhong Liquan Cai Fa Fang Yi Gao | 2019 | Acta Biochimica et Biophysica Sinica2019，51，3： | 7 |
| 12 | Comparative genomic and transcriptomic analyses uncover the molecular basis of high nitrogen-use efficiency in the wheat cultivar Kenong 9204显示文摘Studying the regulatory mechanisms that drive nitrogen-use efficiency(NUE)in crops is important for sustainable agriculture and environmental protection.In this study,we generated a high-quality genome assembly for the high-NUE wheat cultivar Kenong 9204 and systematically analyzed genes related to nitrogen uptake and metabolism.By comparative analyses,we found that the high-affinity nitrate transporter gene family had expanded in Triticeae.Further studies showed that subsequent functional differentiation endowed the expanded family members with saline inducibility,providing a genetic basis for improving the adaptability of wheat to nitrogen deficiency in various habitats.To explore the genetic and molecular mechanisms of high NUE,we compared genomic and transcriptomic data from the high-NUE cultivar Kenong 9204(KN9204)and the low-NUE cultivar Jing 411 and quantified their nitrogen accumulation under high-and low-nitrogen conditions.Compared with Jing 411,KN9204 absorbed significantly more nitrogen at the reproductive stage after shooting and accumulated it in the shoots and seeds.Transcriptome data analysis revealed that nitrogen deficiency clearly suppressed the expression of genes related to cell division in the young spike of Jing 411,whereas this suppression of gene expression was much lower in KN9204.In addition,KN9204 maintained relatively high expression of NPF genes for a longer time than Jing 411 during seed maturity.Physiological and transcriptome data revealed that KN9204 was more tolerant of nitrogen deficiency than Jing 411,especially at the reproductive stage.The high NUE of KN9204 is an integrated effect controlled at different levels.Taken together,our data provide new insights into the molecular mechanisms of NUE and important gene resources for improving wheat cultivars with a higher NUE trait. | Xiaoli Shi Fa Cui Xinyin Han Yilin He Long Zhao Na Zhang Hao Zhang Haidong Zhu Zhexin Liu Bin Ma Shusong Zheng Wei Zhang Jiajia Liu Xiaoli Fan Yaoqi Si Shuiquan Tian Jianqing Niu Huilan Wu Xuemei Liu Zhuo Chen Deyuan Meng Xiaoyan Wang Liqiang Song Lijing Sun Jie Han Hui Zhao Jun Ji Zhiguo Wang Xiaoyu He Ruilin Li Xuebin Chi Chengzhi Liang Beifang Niu Jun Xiao Junming Li Hong-Qing Ling | 2022 | Molecular Plant2022，15，9： | 6 |

| 14 | Comparison of Histological, Microbiological, and Molecular Methods in Diagnosis of Patients with TBLN Having Different Anti-TB Treatment Background显示文摘Objective The influence of anti-tuberculosis(TB) treatment history on tuberculous lymphadenitis(TBLN) diagnosis is unclear. Therefore, this study aims to evaluate the diagnostic methods, including histology, microbiology, and molecular tests, used for TBLN. Methods In this study, suspected patients with TBLN and having different anti-TB treatment background were enrolled. All the samples were tested simultaneously by histology, Ziehl-Neelsen(ZN) staining, mycobacterial culture(culture), Xpert MTB/RIF(xpert), real-time PCR, and high-resolution melting curve PCR(HRM). Thereafter, the performance of these methods on samples with different anti-TB treatment background was assessed. Results In our study, 89 patients were prospectively included 82 patients with TBLN and 7 with other diseases. The overall sensitivities of Xpert, real-time PCR, histology, ZN staining, and culture were 86.6%, 69.5%, 58.5%, 43.9%, and 22.0%, respectively. The anti-TB treatment history revealed dramatic influences on the sensitivity of culture(P < 0.0001). In fact, the treatment that lasted over 3 months also influenced the sensitivity of Xpert(P < 0.05). However, the treatment history did not affect the performance of remaining tests(P > 0.05). For rifampicin drug susceptibility test(DST), the anti-TB treatment showed only significant influence on the success rate of culture DST(P = 0.001), but not on those of Xpert and HRM tests(P > 0.05). Conclusion Other tests as well as culture should be considered for patients with TBLN having retreatment history or over 1-month treatment to avoid false negative results. | CHE Nan Ying HUANG Shao Jun MA Yan HAN Yi LIU Zi Chen ZHANG Chen MU Jing ZHAO Dan QU Yang ZHANG Hai Qing LIU Zhi Dong XU Shao Fa | 2017 | Biomedical and Environmental Sciences2017，30，6： | 6 |
| 15 | Diagenesis and Diagenetic Evolution of Deltaic and Neritic Gas-Bearing Sandstones in the Lower Mingyuefeng Formation of Paleogene, Lishui Sag, East China Sea Shelf Basin: Implications for Depositional Environments and Sequence Stratigraphy Controls显示文摘Gas-bearing deposits in the Lower Mingyuefeng Formation of Paleogene, Lishui Sag, East China Sea Shelf Basin consist of shoreface sandstones of the highstand systems tract(HST) and transgressive systems tract(TST), and deltaic sandstones of the lowstand systems tract(LST) and falling stage systems tract(FSST).Detailed petrographic observations suggest that the diagenetic features and related evolution of these deposits cannot be simply characterized and demonstrated in the depth domain.However, the occurrence of diagenetic minerals systematically depends on the studied interval within the HST, TST, LST, and FSST; therefore, diagenesis in this region can be better constrained when studied in the context of the depositional environments and sequence stratigraphic framework.The eogenetic processes in such settings include:(1) microcrystalline siderite precipitated as concretions in almost all environments and systems tracts, which inhibited further mechanical compaction;(2) grain dissolution and kaolinitization occurred in shoreface HST sandstones and deltaic LST and FSST sandstones;(3) glaucony was locally observed, which did not clearly reflect the controls of facies or sequence stratigraphy; and(4) cementation by pyrite aggregates occurred in the shoreface HST sandstones and deltaic LST sandstones.The mesogenetic diagenesis includes:(1) partial conversion of kaolinite into dickite in deltaic LST sandstones, and minor chlorite cementation in deltaic FSST sandstones;(2) transformation of kaolinite into illite and quartz cementation in deltaic LST and FSST sandstones;(3) frequent precipitation of ankerite and ferroan calcite in shoreface TST sandstones and early HST sandstones, forming baffles and barriers for fluid flow, with common calcite in shoreface HST sandstones as a late diagenetic cement; and(4) formation of dawsonite in the deltaic LST and FSST sandstones, which is interpreted to be a product of the invasion of a CO2-rich fluid, and acts as a good indicator of CO2-bearing reservoirs.This study has thus constructed a reliable conceptual model to describe the spatial and temporal distribution of diagenetic alterations.The results may provide an entirely new conceptual framework and methodology for successful gas exploration in the continental margins of offshore China, thus allowing us to predict and unravel the distribution and quality evolution of clastic reservoirs at a more detailed and reliable scale. | XU Fa ZHANG Penghui ZHANG Jinliang LIU Jinshui HOU Guowei ZHANG Ming LI Jingzhe LIU Shasha GUO Jiaqi MENG Ningning | 2015 | Acta Geologica Sinica(English Edition)2015，89，5： | 5 |
| 16 | Highly luminescent and stable lead-free cesium copper halide perovskite powders for UV-pumped phosphor-converted light-emitting diodes显示文摘Lead halide perovskites have drawn extensive attention over recent decades owing to their outstanding photo-electric performances.However,their toxicity and instability are big issues that need to be solved for further commercialization.Herein,we adopt a facile dry ball milling method to synthesize lead-free Cs3Cu2X5(X=I,CI)perovskites with photoluminescence(PL)quantum yield up to 60%.The optical features including broad emission spectrum,large Stokes shift,and long PL lifetime can be attributed to self-trapped exciton recombination.The as-synthesized blue emissive Cs3Cu2I5 and green emissive Cs3Cu2Cl5 lead-free perovskite powders have good thermal stability and photostability.Furthermore,UV-pumped phosphor-converted light-emitting diodes were obtained by using Cs3Cu2I5 and Cs3Cu2Cl5 as phosphors. | LINGLING XIE BINGKUN CHEN FA ZHANG ZHENG ZHAO XINXIN WANG LIJIE SHI YUE LIU LINGLING HUANG RUIBIN LIU BINGSUO ZOU YONGTIAN WANG | 2020 | Photonics Research2020，8，6： | 5 |
| 17 | Yttria-stabilized-zirconia hollow spheres prepared by atmospheric plasma spray显示文摘Yttria-stabilizecl-zirconia(YSZ) hollow spheres are widely utilized for their novel physical and chemical properties.However,developing a simple and low-cost method for preparing such hollow spheres still remains a great challenge.In this paper,an atmospheric plasma spray(APS) method is introduced,and the formation mechanism of hollow 7YSZ(ZrO_2-7wt%Y_2O_3) spheres is presented.The hollow sphere morphology was observed by scanning electron microscopy(SEM) when agglomerated and sintered 7YSZ powders were used.Additionally,additive composition changes,phase transformations,and the thermal behavior of 7YSZ powders were analyzed by energy dispersive spectroscopy(EDS),X-ray diffractometry(XRD),thermogravimetric analysis(TG) and differential scanning calorimeter analysis(DSC).Furthermore,the phase transformations of agglomerated and sintered 7YSZ powders,7YSZ hollow spheres that annealed at various temperatures for different times are analyzed. | Xiaofeng Zhang Kesong Zhou Fa Chang Chen Song Chunming Deng Siyuan Liang | 2014 | Particuology2014，12，3： | 4 |
| 18 | Effect and mechanism of acute graft versus host disease on early diffuse murine lung injury following allogeneic stem cell transplantation显示文摘To explore the effect and pathogenssis of acute graft-versus-host disease (aGVHD) on early diffuse lung injury in allogeneic hematopoietic stem cell transplantation (allo-HSCT), we established an aGVHD model of C57BL/6→BALB/c mice. Chest computed tomography (CT) scans, histopathology and the levels of cytokines including tumor necrosis factor α (TNFα) and Interferon (IFNγ) in lungs were dynamically detected in recipient mice after transplantation. The incidence of aGVHD was respectively 0%, 0% and 100% in simple irradiation group (A), syngeneic transplant group(B) and allogeneic transplant group (C). Chest CT scans of recipient mice were normal in 3 groups on days +3 and +7 after transplantation. CT showed that two of ten mice had bilateral lung diffuse infiltrate on day +12 (on the brink of death) in group A and 6 of 10 mice had bilateral lung diffuse infiltrate on day +14 (3 d after aGVHD occurring) in group C, and were normal on days +12 and +14 in group B after transplantation. Histopathology of lungs in the 3 groups was similar, consisting of minor interstitial pneumonitis on day +3. Group A showed edema, hyperplasia of epithelial cells and widened alveolar interval on day +7, and epithelial cell necrosis, lymphocyte infiltration, hemorrhage, protein leakage, and local consolidation on day +12. The histopathology of group B showed slight edema of epithelial cells on +7 day, which were slighter than that on day +3, and virtually normal on day +14. The histopathology in group C was characterized by the significant expansion and congestion of capillaries, and lymphocyte infiltration on day +7, the acute pneumonitis was present involving tissue edema, lymphocyte and macrophage infiltration, protein leakage and perivascular inflammation on day +14. In group A, the levels of TNFα were lower on day +7 than on day +3. In group B, the levels of TNFα attained a peak on day +3, which decreased on days +7 and +14. In group C, the levels of TNFα were highest on day +7 and there was a significant difference between those on days +7 and +14 (P=0.816). In group A, the levels of IFNγ on day +7 were higher than on day +3. In group B, the levels of IFNγ increased progressively, but the comparison of IFNγ levels in different times had no statistical significance (P=0.521, 0.118, 0.340). In group C, the levels of IFNγ attained a peak by day +7 and decreased on day +14. aGVHD is the main cause of early non-infectious lung injury. T lymphocytes and TNFα are possibly implicated in the pathogenesis of acute GVHD-induced lung injury. The decreased levels of IFNγ in lung tissues following transplantation might be associated with pulmonary fibrosis in late non-infectious pulmonary complications. | NING Juan, LIU Qi Fa, LUO Xiao Dan, FAN Zhi Ping & Zhang Yu Department of Hematology, Southern Hospital, Southern Medical University, Guang Zhou 510515, China | 2009 | Science China(Life Sciences)2009，52，11： | 4 |

| 20 | Vegetable and Fruit Consumption among Chinese Adults and Associated Factors: A Nationally Representative Study of 170,847 Adults显示文摘Objective This study examined vegetable and fruit(VF) consumption rate and its associated factors among Chinese adults.Methods Nationally representative data from the 2013 China Chronic Disease Surveillance survey were used. Dietary intake data, including VF consumption during the last 12 months, were collected. All analyses were weighted to obtain nationally representative estimates. Associations between VF consumption and other factors(e.g., meal frequency and physical activity) were examined through logistic regression analysis.Results The average fruit consumption was 102.3 g/day(95% CI: 97.0‐107.6) and the average vegetable consumption was 350.6 g/day(95% CI: 339.3‐361.8). Over half(53.2%, 95% CI: 50.9‐55.4) of Chinese adults met the VF consumption of 400 g/day recommended by the World Health Organization(WHO). Rural residents had a higher prevalence of low VF consumption rate than urban residents[49.20%(95% CI: 46.2%‐52.2%) vs. 44.0%(95% CI: 41.7%‐46.3%) P < 0.01]. Old age(OR = 1.01, 95% CI:1.00‐1.01), low educational level, low income, minority ethnicity(OR = 1.41, 95% CI: 1.15‐1.74),underweight(OR = 1.17, 95% CI: 1.03‐1.33), single marital status(OR = 1.20, 95% CI: 1.08‐1.33), low health literacy, irregular breakfast(OR = 1.20, 95% CI: 1.04‐1.38) or lunch(OR = 1.58, 95% CI: 1.26‐1.99)habits, and no leisure‐time physical activity were associated with low VF consumption.Conclusion Only half of Chinese adults met the VF consumption recommended by the WHO. Low socio‐economic status, irregular diet, and poor health literacy were likely associated with low VF consumption. National efforts and programs are needed to promote VF consumption. | LI Yi Chong JIANG Bo ZHANG Mei HUANG Zheng Jing DENG Qian ZHOU Mai Geng ZHAO Zhen Ping WANG You Fa WANG Li Min | 2017 | Biomedical and Environmental Sciences2017，30，12： | 3 |
