| 3 | Does Helicobacter pylori infection play a role in iron deficiency anemia? A meta-analysis显示文摘AIM:To perform a meta-analysis of observational studies and randomized controlled trials(RCTs)on the association between Helicobacter pylori(H.pylori)and iron deficiency anemia(IDA).METHODS:A defined search strategy was used to search Medline,Embase,the Cochrane Library,Clinical Trials,Cochrane Central Register of Controlled Trials,Premedline and Healthstar.Odds ratio(OR)was used to evaluate observational epidemiology studies,and weighted mean difference(WMD)was used to demonstrate the difference between control and intervention groups.RESULTS:Fifteen observational studies and 5 RCTs were identified and used for calculation.The pooled OR for observational studies was 2.22(95%CI:1.52-3.24,P<0.0001).The WMD for hemoglobin(HB) was 4.06 g/L(95%CI:-2.57-10.69,P=0.01),and the WMD for serum ferritin(SF)was 9.47μg/L(95%CI:-0.50-19.43,P<0.0001).Results were heterogeneous for all comparisons.CONCLUSION:This meta-analysis on observational studies suggests an association between H.pylori and IDA.In RCTs,eradication of H.pylori can improve HB and SF levels but not significantly. | Qu, Xin-Hua Huang, Xiao-Lu Xiong, Ping Zhu, Cui-Ying Huang, You-Liang Lu, Lun-Gen Sun, Xu Rong, Lan Zhong, Liang Sun, Da-Yu Lin, Hai Cai, Ming-Ci Chen, Zhi-Wei Hu, Bing Wu, Lian-Ming Jiang, Yi-Bin Yan, Wei-Li | 2010 | World Journal of Gastroenterology2010,16,7: | 34 |
| 4 | Outbreak of Dengue Fever in Central China,2013显示文摘In 2013,the first dengue fever(DF) outbreak in central China was reported in the central of Henan province,northern temperate regions,although they have been sequentially recorded in Southern China.106 suspected DF cases were reported and 73 patients were confirmed dengue virus type 3(DEN-3) infections.62/392(15.8%) local health persons showed DEN antibodies positive.To this day Henan is the northernmost province in China which has been reported about outbreak of DF and what is important is that it warns us the endemic range of DF has been expanded geographically in China. | HUANG Xue Yong MA Hong Xia WANG Hai Feng DU Yan Hua SU Jia LI Xing Le TANG Xiao Yan MA Hong Peng ZU Bing Can ZHANG Qiao Hong CHEN Hao Min XU Bian Li | 2014 | Biomedical and Environmental Sciences2014,27,11: | 30 |
| 5 | A selective tropism of transfused oval cells for liver显示文摘AIM: To explore the biological behaviors of hepatic oval cells after transfused into the circulation of experimental animals.METHODS: Oval cells from male SD rat were transfused into the circulation of a female rat which were treated by a 2-AAF/CCl4 program, through caudal vein. Sex-determining gene sry which located on Y chromosome was examined by PCR and in situ hybridization technique in liver, kidney and spleen of the experimental animals, respectively.RESULTS: The results of the cell-transplant experiment showed that the srygene was detectable only in the liver but not in spleen and kidney of the experimental rats, and no signals could be detected in the control animals. It can be also morphologically proved that some exogenous cells had migrated into the parenchyma of the liver and settled there.CONCLUSION: The result means that there are exogenous cells located in the liver of the experimental animal and the localization is specific to the liver. This indicates that some 'signal molecules' must exist in the circulation of the rats treated by 2-AAF/CCl4. These 'signal molecules' might play an important role in specific localization and differentiation of transfused oval cells. | Jian-Zhi Chen Hai Hong Jin Xiang Ling Xue Guo-Qiang Zhao Department of Pathology, Medical School of Sun Yat-Sen University, Guangzhou 510080, Guangdong Province, China | 2003 | World Journal of Gastroenterology2003,9,3: | 25 |
| 6 | Analysis of the Results of Two Nationwide Surveys on Clonorchis sinensis Infection in China显示文摘Objective To examine Clonorchis sinensis infection in China and evaluate the effectiveness of efforts to prevent and control it,two nationwide surveys were undertaken in 31 provinces,autonomous regions,and municipalities(PAMs) during 1988-92(the 1990 survey) and during 2001-04(the 2003 survey).Methods During the period 2001-04,two sampling methods were applied.The first method repeated the stratified cluster random sampling used in the 1990 survey;the second method applied two-characteristic stratified cluster random sampling in 27 PAMs-the 2003 endemic area(EA) survey.The Kato-Katz thick smear method was used for the nationwide survey.Results The infection rates of Clonorchis sinensis in the 1990 and 2003 surveys were 0.311% and 0.579%,respectively.The infection rate was 2.40% in the 2003 EA survey,and it was estimated that 12.49 million people in China were infected with Clonorchis sinensis.Conclusion The 2003 survey showed that the standardized infection rate of Clonorchis sinensis increased by 74.85% compared with the 1990 survey.The infection rate in males was higher than in females;the infection rate among people eating raw fish or eating out frequently was higher than among those who did not. | CHEN Ying Dan ZHOU Chang Hai XU Long Qi | 2012 | Biomedical and Environmental Sciences2012,25,2: | 22 |
| 7 | A Strigolactone Biosynthesis Gene Contributed to the Green Revolution in Rice显示文摘Plant architecture is a complex agronomic trait and a major factor of crop yield,which is affected by several important hormones.Strigolactones(SLs)are identified as a new class hormoneinhibiting branching in many plant species and have been shown to be involved in various developmental processes.Genetical and chemical modulation of the SL pathway is recognized as a promising approach to modify plant architecture.However,whether and how the genes involved in the SL pathway could be utilized in breeding still remain elusive.Here,we demonstrate that a partial loss-of-function allele of the SL biosynthesis gene,HIGH TILLERING AND DWARF 1/DWARF17(HTD1/D17),which encodes CAROTENOID CLEAVAGE DIOXYGENASE 7(CCD7),increases tiller number and improves grain yield in rice.We found that the HTD1 gene had been widely utilized and co-selected with Semidwarf 1(SD1),both contributing to the improvement of plant architecture in modern rice varieties since the Green Revolution in the 1960s.Understanding how phytohormone pathway genes regulate plant architecture and how they have been utilized and selected in breeding will lay the foundation for developing the rational approaches toward improving crop yield. | Yuexing Wang Lianguang Shang Hong Yu Longjun Zeng Jiang Hu Shen Ni Yuchun Rao Sanfeng Li Jinfang Chu Xiangbing Meng Lei Wang Ping Hu Jijun Yan Shujing Kang Minghao Qu Hai Lin Tao Wang Quan Wang Xingming Hu Hongqi Chen Bing Wang Zhenyu Gao Longbiao Guo Dali Zeng Xudong Zhu Guosheng Xiong Jiayang Li Qian Qian | 2020 | Molecular Plant2020,13,6: | 23 |
| 8 | Climate and litter C/N ratio constrain soil organic carbon accumulation显示文摘Soil organic carbon(SOC) plays critical roles in stabilizing atmospheric CO2 concentration, but the mechanistic controls on the amount and distribution of SOC on global scales are not well understood. In turn, this has hampered the ability to model global C budgets and to find measures to mitigate climate change. Here, based on the data from a large field survey campaign with 2600 plots across China’s forest ecosystems and a global collection of published data from forested land, we find that a low litter carbon-to-nitrogen ratio(C/N) and high wetness index(P/PET, precipitation-to-potentialevapotranspiration ratio) are the two factors that promote SOC accumulation, with only minor contributions of litter quantity and soil texture. The field survey data demonstrated that high plant diversity decreased litter C/N and thus indirectly promoted SOC accumulation by increasing the litter quality. We conclude that any changes in plant-community composition, plant-species richness and environmental factors that can reduce the litter C/N ratio, or climatic changes that increase wetness index, may promote SOC accumulation. The study provides a guideline for modeling the carbon cycle of various ecosystem scales and formulates the principle for land-based actions for mitigating the rising atmospheric CO2 concentration. | Guoyi Zhou Shan Xu Philippe Ciais Stefano Manzoni Jingyun Fang Guirui Yu Xuli Tang Ping Zhou Wantong Wang Junhua Yan Gengxu Wang Keping Ma Shenggong Li Sheng Du Shijie Han Youxin Ma Deqiang Zhang Juxiu Liu Shizhong Liu Guowei Chu Qianmei Zhang Yuelin Li Wenjuan Huang Hai Ren Xiankai Lu Xiuzhi Chen | 2019 | National Science Review2019,6,4: | 21 |
| 9 | Modern stalagmite oxygen isotopic composition and its implications of climatic change from a high-elevation cave in the eastern Qinghai-Tibet Plateau over the past 50 years显示文摘An oxygen isotope record of a stalagmite from Huanglong Cave in the eastern Qinghai-Tibet Plateau dated with 230Th and 210Pb methods provides variations of the Asian monsoon with an average resolu-tion of 1 year over the past 50 years. This study shows that the δ18O of dripwater in the cave represents the annual mean δ18O of local meteoric precipitation and the stalagmites were deposited in isotopic equilibrium. A comparison of the stalagmite δ18O record with instrumentally meteorological data indi-cates that shifts of the δ18O are largely controlled by the amount effect of meteoric precipitation con-veyed through the southwest monsoon(the Indian monsoon) and less affected by temperature. Therefore,the variations of δ18O record reflect the changes in monsoon precipitation on inter-annual time scales under the influence of the southwest monsoon. Like many other stalagmite δ18O records in the Asian monsoon regions,the δ18O record of the stalagmite from Huanglong Cave also reveals a gradually enriched trend during the past 50 years,i.e. relatively enriched in 18O. This trend may indicate the decline of the Asian monsoon intensity which is consistent with the decrease of monsoon indices. The weakening of the modern Asian monsoon well matched with the temperature changes in strato-sphere,which may illustrate that the weakening of the monsoon mainly results from the lowering of solar radiation. | YANG XunLin ZHANG PingZhong CHEN FaHu HUH Chih-an LI HongChun CHENG Hai Kathleen R.

| 12 | Long-term outcomes of endoscopic resection for small(≤4.0cm) gastric gastrointestinal stromal tumors originating from the muscularis propria layer显示文摘AIM To evaluate the long-term efficacy of endoscopic resection(ER) for small(≤ 4.0 cm) gastric gastrointestinal stromal tumors(GISTs) originating from the muscularis propria layer.METHODS Between June 2005 and February 2015, we retrospectively analyzed 229 consecutive patients with gastric MP-GISTs who underwent ER with a follow-up at least 36 mo. The main outcome measurements included complete resection rate, complications, and long-term follow-up outcomes.RESULTS ER included endoscopic muscularis excavation in 179 cases, endoscopic full-thickness resection in 32 cases, and submucosal tunneling endoscopic resection in 18 cases. The median size of GISTs was 1.90 cm. Of the 229 GISTs, 147 were very low risk, 72 were low risk, 8 were intermediate risk, and 2 were high risk. Shortterm outcomes showed the complete resection rate was 96.5%, and 8 patients(3.5%) had complications. Of the 8 patients with complications, only one patient required surgical intervention. Long-term outcomes showed 225 patients were actively followed-up until composition of this manuscript. The remaining 4 patients were lost because of unrelated death. During the follow-up period(median, 57 mo), no residual, recurrent lesions, or distant metastasis were detected in any patients. Binary logistic regression analysis showed tumor size was a risk factor associated with a high mitotic index(≥ 5/50 HPF) of GISTs(P = 0.002).CONCLUSION ER seems to be an effective and safe method for gastric MP-GISTs ≤ 4.0 cm, and, for some intermediate or high risk GISTs, adjuvant therapy and/or additional surgery might be required to reduce the risk of recurrence or metastasis. | Yu Zhang Xin-Li Mao Xian-Bin Zhou Hai Yang Lin-Hong Zhu Guang Chen Li-Ping Ye | 2018 | World Journal of Gastroenterology2018,24,27: | 18 |
| 13 | Effectiveness of Different Waist Circumference Cut-off Values in Predicting Metabolic Syndrome Prevalence and Risk Factors in Adults in China显示文摘Objective To study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome(MetS) and risk factors in adults in China. Methods A cross-sectional survey was condcuted in 14 provinces(autonomous region, municipality) in China. A total of 47 325 adults aged ≥20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation(IDF) criteria and modified IDF criteria.Results The age-standardized prevalence of MetS was 24.2%(22.1% in men and 25.8% in women) and 19.5%(22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1%(8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity(90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China. | ZHOU Hai Cheng LAI Ya Xin SHAN Zhong Yan JIA Wei Ping YANG Wen Ying LU Ju Ming WENG Jian Ping JI Li Nong LIU Jie TIAN Hao Ming JI Qiu He ZHU Da Long CHEN Li GUO Xiao Hui ZHAO Zhi Gang Li Qiang ZHOU Zhi Guang GE Jia Pu SHAN Guang Liang | 2014 | Biomedical and Environmental Sciences2014,27,5: | 17 |
| 14 | Overcoming multi-drug resistance by anti-MDR1 ribozyme显示文摘AIM: To reverse multidrug resistance (MDR) of HepG2 by anti-MDR1 hammerhead ribozyme.METHODS: We developed an anti-MDR1 hammerhead ribozyme and delivered it to P-gp-overproducing human hepatocarcinoma cell line HepG2 by a retroviral vector containing RNA polymerase Ⅲ promoter. We detected the expression of mdr1/Pgp and Rz in HepG2, HepG2 multidrugresistant cell line and HepG2 Rz-transfected cells by realtime RT-PCR, semi-quantitative RT-PCR and Western blot methods. Moreover, MTT assay was tested to detect sensitivity of these ribozyme-transfected cells, and Rhodamine123 (Rh123) applied to test the function of Pgp.RESULTS: The Rz- transfected HepG2 cells became doxorubicin-sensitive, concomitant with the decreases in MDR1 expression, P-gp amounts and efflux pump function.CONCLUSION: The approaches using either retrovirus or liposome-mediated transfer of anti-MDR1 ribozyme may be selectively applicable to the treatment of MDR cells. | Hai Wang Xiao-Ping Chen Fa-Zu Qiu The Hepatic Center of Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology,Wuhan,430030,HuBei Province,China | 2003 | World Journal of Gastroenterology2003,9,7: | 17 |
| 15 | Surgical approaches for stage Ⅰ and Ⅱ thymoma-associated myasthenia gravis:feasibility of complete video-assisted thoracoscopic surgery (VATS) thymectomy in comparison with trans-sternal resection显示文摘Complete resection could be achieved in virtually all myasthenic patients with Masaoka stage Ⅰ and Ⅱ thymoma using the trans-sternal technique.Whether this is appropriate for minimally invasive approach is not yet clear.We evaluated the feasibility of complete video-assisted thoracoscopic surgery (VATS) thymectomy for the treatment of Masaoka stage Ⅰ and Ⅱ thymoma-associated myasthenia gravis,compared to conventional trans-sternal thymectomy.We summarized 33 patients with Masaoka stage Ⅰ and Ⅱ thymoma-associated myasthenia gravis between April 2006 and September 2011.Of these,15 patients underwent right-sided complete VATS (the VATS group) by using adjuvant pneuomomediastinum,comparing with 18 patients using the trans-sternal approach (the T3b group).No intraoperative death was found and no VATS case required conversion to median sternotomy.Significant differences between the two groups regarding duration of surgery and volume of intraoperative blood loss (P=0.001 and P < 0.001,respectively) were observed.Postoperative morbidities were 26.7% and 33.3% for the VATS and T3b groups,respectively.All 33 patients were followed up for 12 to 61 months in the study.The cumulative probabilities of reaching complete stable remission and effective rate were 26.7% (4/15) and 93.3% (14/15) in the VATS group,which had a significantly higher complete stable remission and effective rate than those in the T3b group (P=0.026 and P=0.000,respectively).We conclude that VATS thymectomy utilizing adjuvant pneuomomediastinum for the treatment of stage Ⅰ and Ⅱ thymoma-associated myasthenia gravis is technically feasible but deserves further investigation in a large series with long-term follow-up. | Zhicheng He Quan Zhu Wei Wen Liang Chen Hai Xu Hai Li | 2013 | The Journal of Biomedical Research2013,27,1: | 15 |

| 17 | Bacterial infection triggers and complicates acute-on-chronic liver failure in patients with hepatitis B virus-decompensated cirrhosis: A retrospective cohort study显示文摘BACKGROUND Reports on bacterial infection(BI)in decompensated cirrhosis(DC)is mainly from alcoholic cirrhosis.The role of BI as a trigger or complication of acute-onchronic liver failure(ACLF)in patients with hepatitis B virus decompensated cirrhosis(HBV-DC)remains to be investigated.AIM To investigate the impact of BI on the outcomes of the patients with HBV-DC admitted into the hospital with or without ACLF.METHODS This retrospective study included patients with HBV-DC admitted to two tertiary centers in China.In-hospital overall survival,90-d transplant-free survival,5-year post-discharge survival,and cumulative incidence of ACLF were evaluated.Risk factors for death were analyzed considering liver transplantation as a competing event.RESULTS A total of 1281 hospitalized HBV-DC patients were included;284 had ACLF at admission.The overall prevalence of BI was 28.1%.The patients with BI had a significantly lower in-hospital survival and transplant-free 90-d survival than those without,in both the patients admitted with and without ACLF.The presence of BI significantly increased the risk of developing ACLF[subdistribution hazard ratio(sHR)=2.52,95%CI:1.75-3.61,P<0.001]in the patients without ACLF.In the patients discharged alive,those who had an episode of BI had a significantly lower 5-year transplant-free survival.BI was an independent risk factor for death in the patients admitted without ACLF(sHR=3.28,95%CI:1.93-5.57),while in ACLF admissions,the presence of pneumonia,but not other type of BI,independently increased the risk of death(sHR=1.87,95%CI:1.24-2.82).CONCLUSION BI triggers ACLF in patients with HBV-DC and significantly impairs short-term survival.HBV-DC patients should be monitored carefully for the development of BI,especially pneumonia,to avoid an adverse outcome. | Zhu-Jun Cao Yu-Han Liu Chuan-Wu Zhu Shan Yin Wei-Jing Wang Wei-Liang Tang Gang-De Zhao Yu-Min Xu Lu Chen Tian-Hui Zhou Ming-Hao Cai Hui Wang Wei Cai Shi-San Bao Hai Li Qing Xie | 2020 | World Journal of Gastroenterology2020,26,6: | 15 |
| 18 | Evaluating the Nutritional Status of Oncology Patients and Its Association with Quality of Life显示文摘Objective The primary aim of the study was to compare two nutritional status evaluation tools: the Patient-Generated Subjective Global Assessment(PG-SGA) and Nutritional Risk Screening(NRS-2002). Using the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire 30(EORTC QLQ-C30), the second aim was to provide constructive advice regarding the quality of life of patients with malignancy. Methods This study enrolled 312 oncology patients and assessed their nutritional status and quality of life using the PG-SGA, NRS-2002, and EORTC QLQ-C30. Results The data indicate that 6% of the cancer patients were well nourished. The SGA-A had a higher sensitivity(93.73%) but a poorer specificity(2.30%) than the NRS-2002(69.30% and 25.00%, respectively) after comparison with albumin. There was a low negative correlation and a high similarity between the PG-SGA and NRS-2002 for evaluating nutritional status, and there was a significant difference in the median PG-SGA scores for each of the SGA classifications(P < 0.001). The SGA-C group showed the highest PG-SGA scores and lowest body mass index. The majority of the target population received 2 points for each item in our 11-item questionnaire from the EORTC QLQ-C30. Conclusion The data indicate that the PG-SGA is more useful and suitable for evaluating nutritional status than the NRS-2002. Additionally, early nutrition monitoring can prevent malnutrition and improve the quality of life of cancer patients. | ZHANG Ya Hui XIE Fang Yi CHEN Ya Wen WANG Hai Xia TIAN Wen Xia SUN Wen Guang WU Jing | 2018 | Biomedical and Environmental Sciences2018,31,9: | 14 |
| 19 | Effects of planting patterns on yield, quality, and defoliation in machine-harvested cotton显示文摘The aim of this study was to elucidate the effects of different machine-harvested cotton-planting patterns on defoliation,yield,and fiber quality in cotton and to provide support for improving the quality of machine-harvested cotton.In the 2015 and 2016 growing seasons,the Xinluzao 45(XLZ45)and Xinluzao 62(XLZ62)cultivars,which are primarily cultivated in northern Xinjiang,were used as study materials.Conventional wide-narrow row(WNR),wide and ultra-narrow row(UNR),wide-row spacing with high density(HWR),and wide-row spacing with low density(LWR)planting patterns were used to assess the effects of planting patterns on defoliation,yield,and fiber quality.Compared with WNR,the seed cotton yields were significantly decreased by 2.06–5.48%for UNR and by 2.50–6.99%for LWR,respectively.The main cause of reduced yield was a reduction in bolls per unit area.The variation in HWR yield was–1.07–1.07%with reduced bolls per unit area and increased boll weight,thus demonstrating stable production.In terms of fiber quality indicators,the planting patterns only showed significant effects on the micronaire value,with wide-row spacing patterns showing an increase in the micronaire values.The defoliation and boll-opening results showed that the number of leaves and dried leaves in HWR was the lowest among the four planting patterns.Prior to the application of defoliating agent and before machine-harvesting,the numbers of leaves per individual plant in HWR were decreased by 14.45 and 25.00%on average,respectively,compared with WNR,while the number of leaves per unit area was decreased by 27.44 and 36.21%on average,respectively.The rates of boll-opening and defoliation in HWR were the highest.Specifically,the boll-opening rate before defoliation and machine-harvesting in HWR was 44.54 and 5.94%higher on average than in WNR,while the defoliation rate prior to machine-harvesting was 3.45%higher on average than in WNR.The numbers of ineffective defoliated leaves and leaf trash in HWR were the lowest,decreased by 33.40 and 32.43%,respectively,compared with WNR.In conclusion,the HWR planting pattern is associated with a high and stable yield,does not affect fiber quality,promotes early maturation,and can effectively decrease the amount of leaf trash in machine-picked seed cotton,and thus its use is able to improve the quality of machine-harvested cotton. | WANG Fang-yong HAN Huan-yong LIN Hai CHEN Bing KONG Xian-hui NING Xin-zhu WANG Xu-wen YU Yu LIU Jing-de | 2019 | Journal of Integrative Agriculture2019,18,9: | 14 |
| 20 | Combined and interactive effects of interference fit and preloads on composite joints显示文摘The combined and interactive effects of the bolt-hole fit conditions and the preloads of the fasteners on the load carrying capacity of single-lap composite-to-titanium bolted joints have been investigated both experimentally and numerically. Quasi-static tests of the hybrid joints with different fit conditions are implemented, and a three dimensional finite element progressive failure analysis model is proposed to predict the influences of the bolt-hole fit conditions and fastener's preloads on the mechanical behaviors of the joints. Based on the experimental validated simulation method, a multi-factor, mixed levels orthogonal design table and the analysis of variance method are used to arrange the simulation conditions and to further study the interactive effects of preloads and fit conditions. Through the analysis of the results, for the researched double bolt, single-lap composite-titanium joints, it is found that: the effects of both the interference fit and the preloads change from positive into negative mode with the increase of the interference fit values or preload values; appropriate bolt-hole fit conditions and preloads can improve the bolt-hole contact conditions of the loaded joints, and then retard the fiber failures around the fastener holes, and increase the load carrying capacity of the joints eventually; the interactive effect of the bolt-hole interference fit conditions and preloads cannot be ignored and the parameters need to be considered together and synthetically as the joints are being optimized. | Liu Longquan Zhang Junqi Chen Kunkun Wang Hai | 2014 | Chinese Journal of Aeronautics2014,27,3: | 13 |
