China faces a disproportionate cancer burden to the population size and is undergoing a transition in the cancer spectrum.We extracted data in five aspects of cancer incidence,mortality,survival,staging distributions,and attribution to risk factors in China,the USA and worldwide from open-source databases.We conducted a comprehensive secondary analysis of cancer profiles in China in the above aspects,and compared cancer statistics between China and the USA.A total of 4,546,400 new cancer cases and 2,992,600 deaths occurred in China in 2020,accounting for 25.1%and 30.2%of global cases,respectively.lifestyle-related cancers including lung cancer,colorectal cancer,and breast cancer showed an upward trend and have been the leading cancer types in China.41.6%of new cancer cases and 49.3%of cancer deaths occurred in digestive-system cancers in China,and the cancers of esophagus,nasopharynx,liver,and stomach in China accounted for over 40%of global cases.Infection-related cancers showed the highest population-attributable fractions among Chinese adults,and most cancers could be attributed to behavioral and metabolic factors.The proportions of stage I for most cancer types were much higher in the USA than in China,except for esophageal cancer(78.2%vs.41.1%).The 5-year relative survival rates in China have improved substantially during 2000–2014,whereas survival for most cancer types in the USA was significantly higher than in China,except for upper gastrointestinal cancers.Our findings suggest that although substantial progress has been made in cancer control,especially in digestive system cancers in China,there was still a considerable disparity in cancer burden between China and the USA.More robust policies on risk factors and standardized screening practices are urgently warranted to curb the cancer growth and improve the prognosis for cancer patients.

An increasing cancer incidence among adults younger than 50 years has been reported for several types of cancer in multiple countries.We aimed to report cancer profiles and trends among young adults in China.Data from the China Cancer Registry Annual Report were used to estimate incidence and mortality among young adults(ages 20–49 years)in China in 2017,and an age-period-cohort model was employed to estimate the average annual percent change(AAPC)in incidence and mortality from 2000 to 2017.All 25 cancer types were grouped into obesity-or overweight-associated cancers(12 cancer types)and additional cancers(13 cancer types).In 2017,there were 681,178new cases and 214,591 cancer deaths among young adults in China.Among young adults,the most common cancers were thyroid,breast,cervical,liver,lung,and colorectal cancer,and the leading causes of cancer deaths were liver,lung,cervical,stomach,breast,and colorectal cancer.From 2000 to 2017,the cancer incidence increased for all cancers combined among young adults,with the highest AAPC(1.46%)for adults aged 20–24 years,while cancer mortality decreased,with the highest AAPC(-1.63%)for those aged 35–39 years.In conclusion,the cancer incidence in China has increased among young adults,while cancer mortality has decreased for nearly all ages.Cancer control measures,such as obesity control and appropriate screening,may contribute to reducing the increasing cancer burden among young adults.

Selenium(Se)is an essential mineral element for human and other animals,and has been proved to improve plant growth and development and tolerance to different abiotic stresses.Selenium biofortification is considered to be a key strategy to increase the selenium content of edible parts of crops,which is helpful for improving human health.In this work,foliar fertilization with different concentrations and selenium forms was carried out on two wheat varieties at the flowering stage to compare the selenium enrichment effect of Na_(2)SeO_(3),methylselenized selenocysteine(MSC),methylselenized glucose(MSG)and methylselenized lactide(MSL)in wheat grains.Surprisingly,MSG was found to be the preferable fertilizer.After the application of MSG,the highest selenium content in wheat gains reached 6 mg/kg in this experiment,and the average selenium content was 2-4 times versus that of Na_(2)SeO_(3)application.Since MSG has high utilization rate and is easily available at relatively low cost,it can be employed as a potential selenium source for selenium biofortification to enhance the added value of agricultural industry.

In 2020, stomach cancer was the fifth most commonly diagnosed cancer and the fourth leading cause of cancer-related death worldwide. Due to the relatively huge population base and the poor survival rate, stomach cancer is still a threat in China, and accounts for nearly half of the cases worldwide. Fortunately, in China, the incidence and mortality rates of stomach cancer presented a declining trend owing to the change of individual life styles and the persistent efforts to prevent stomach cancer from the governments at all levels. Helicobacter pylori(H. pylori)infection, poor eating habits, smoking, history of gastrointestinal disorders, and family history of stomach cancer are the main risk factors for stomach cancer in China. As a result, by taking risk factors for stomach cancer into account, specific preventive measures, such as eradicating H. pylori and implementing stomach cancer screening projects, should be taken to better prevent and decrease the burden of stomach cancer.

In this review,we offer a concise overview of liver cancer epidemiology in China and worldwide from the official databases of GLOBOCAN 2020 and the National Cancer Registry in China.We also summarized the evidence for the main risk factors associated with liver cancer risk and discuss strategies implemented in China to control the liver cancer burden.Overall,liver cancer was the sixth most commonly diagnosed cancer and the third leading cause of cancer-related death worldwide in 2020.Although China contributed to nearly half of cases across the world alone,the incidence and mortality rates of liver cancer presented a declining trend owing to the persistent efforts from the governments at all levels.The current liver cancer burden in China still faces an arduous challenge due to the relatively large population base as well as the substantially low survival rate(12.1%).To better control the liver cancer burden with the lowest cost,specific measures should be conducted by reducing exposure to established risk factors such as hepatitis B infection and aflatoxin.The promotion of surveillance is also an important method to prolong the survival of liver cancer.This review will provide basic information for future direction on the control of liver cancer burden.

Do exercise therapies restore the deficits of joint position sense in patients with chronic ankle instability? A systematic review and meta-analysis

引用

运动医学与健康科学(英文) 2023年第1期5卷 67-73页

作者： Xiao'ao Xue Weichu Tao Xiaoyun Xu Zhengbiao Jin qianru li Yiran Wang Xicheng Gu Ru Wang Yinghui Hua Department of Sports Medicine Huashan HospitalFudan UniversityShanghai200040China School of Exercise and Health Shanghai University of SportShanghai200438China

To determine whether existing exercise therapies can restore the joint position sense(JPS)deficits of patients with chronic ankle instability(CAI)when compared with controlled non-training patients.Seven databases were searched using ankle,injury,proprioception,and exercise-therapy-related terms.Peer-reviewed human studies in English that used the absolute errors score of joint position reproduction(JPR)test to compare the JPS of injured ankles in CAI patients before and after exercise therapy and non-training controls were included and analyzed.Demographic information,sample size,description of exercise therapies,methodological details of the JPR test,and absolute error scores were extracted by two researchers independently.Meta-analysis of the differences in JPS changes(i.e.,absolute errors after treatment minus the baseline)between the exercise therapies and non-training controls was performed with the weighted mean difference(WMD)and 95%confidence interval(CI).Seven studies were finally included.Meta-analyses revealed significantly higher improvements in passive JPS during inversion with,WMD?1.54and eversion,of,WMD?1.80,after exercise therapies when compared with non-training controls.However,no significant changes in the impaired side active JPS were observed with regard to inversion and eversion.Existing exercise therapies may have a positive effect on passive JPS during inversion and eversion,but do not restore the active JPS deficits of injured ankles in patients with CAI when compared with non-training controls.Updated exercise components with a longer duration that focus on active JPS with longer duration are needed to supplement the existing content of exercise therapies.

Objective: This study aims to provide an analysis of the current status and trends of lung cancer incidence and mortality rates in China, comparing trends with those in the United States(U.S.).Methods: Data on lung cancer incidence and mortality rates spanning 2000 to 2018 were extracted from the China Cancer Registry Annual Report and the Surveillance, Epidemiology, and End Results database for China and the U.S., respectively. Crude incidence and mortality rates were calculated by sex and age, with age-standardized incidence rates(ASIR) and mortality rates(ASMR) calculated using the Segi-Doll world standard population.Trend analyses employed Joinpoint regression models to determine average annual percentage change(AAPC).The study also assessed the proportion of new cases and deaths by sex and age.Results: In 2018, the ASIR of lung cancer for males in China was 50.72 per 100,000 and the ASMR was 39.69 per 100,000, the ASIR for females was 26.25 per 100,000 and the ASMR was 15.24 per 100,000. Both ASIR and ASMR were higher in males and the highest in the population aged 65 years and older, with the lowest among those aged 20-49 years. In China, female ASIR demonstrated an increasing trend(AAPC: 1.16%), while ASMR decreased in both sexes(AAPCs:-0.48% for males,-1.00% for females). The U.S. exhibited decreasing trends in both ASIR and ASMR across sexes and age groups.Conclusions: The study identified an increasing trend in lung cancer incidence among females and a decreasing mortality trend in both sexes in China. These trends are likely linked to factors such as smoking prevalence,advancements in cancer screening, and improved medical care. The findings underscore the need for tailored lung cancer prevention measures in China, particularly the reinforcement of anti-smoking policies.

Chronic ankle instability is associated with proprioception deficits:A systematic review and meta-analysis

引用

Journal of Sport and Health Science 2021年第2期10卷 182-191页

作者： Xiao’ao Xue Tengjia Ma qianru li Yujie Song Yinghui Hua Department of Sports Medicine Huashan HospitalFudan UniversityShanghai 200040China

Background:Acute ankle injury causes damage to joint mechanoreceptors and deafferentation and contributes to proprioception deficits in patients with chronic ankle instability(CAI).We aimed to explore whether deficits of proprioception,including kinesthesia and joint position sense(JPS),exist in patients with CAI when compared with the uninjured contralateral side and healthy people.We hypothesized that proprioception deficits did exist in patients with CAI and that the deficits varied by test methodologies.Methods:The study was a systematic review and meta-analysis.We identified studies that compared kinesthesia or JPS in patients with CAI with the uninjured contralateral side or with healthy controls.Meta-analyses were conducted for the studies with similar test procedures,and narrative syntheses were undertaken for the rest.Results:A total of 7731 studies were identified,of which 30 were included for review.A total of 21 studies were eligible for meta-analysis.Compared with the contralateral side,patients with CAI had ankle kinesthesia deficits in inversion and plantarflexion,with a standardized mean difference(SMD)of 0.41 and 0.92,respectively,and active and passive JPS deficits in inversion(SMD=0.92 and 0.72,respectively).Compared with healthy people,patients with CAI had ankle kinesthesia deficits in inversion and eversion(SMD=0.64 and 0.76,respectively),and active JPS deficits in inversion and eversion(SMD=1.00 and 4.82,respectively).Proprioception deficits in the knee and shoulder of patients with CAI were not statistically significant.Conclusion:Proprioception,including both kinesthesia and JPS,of the injured ankle of patients with CAI was impaired,compared with the uninjured contralateral limbs and healthy people.Proprioception varied depending on different movement directions and test methodologies.The use of more detailed measurements of proprioception and interventions for restoring the deficits are recommended in the clinical management of CAI.

Journal of Integrative Plant Biology 2020年第12期62卷 1983-1996页

作者： Baixiao Niu Hui Deng Tingting li Sandeep Sharma Qianbin Yun qianru li Zhiguo E Chen Chen Jiangsu Key Laboratory of Crop Genetics and Physiology/Key Laboratory of Plant Functional Genomics of the Ministry of Education/Jiangsu Key Laboratory of Crop Genomics and Molecular Breeding/Jiangsu Co‐Innovation Center for Modern Production Technology of Grain Crops Agricultural College of Yangzhou UniversityYangzhou 225009China Key Laboratory of Rice Biology China National Rice Research InstituteHangzhou 310000China Department of Genetics and Plant Breeding Institute of Agricultural SciencesBHUVaranasi 221005India

Following double fertilization,plant endosperm nuclei undergo syncytial divisions,followed by synchro-nous cellularization.Cellularization is a key event during endosperm development,but our understanding of its regulation is limited to Arabidopsis.In this study we show that OsbZIP76 regulates cellularization in rice(Oryza sativa).Activation of OsbZIP76 coincided with the initiation of cellularization,and its knockdown or knockout mutants exhibited precocious cellularization.Genes involved in en-dosperm development or starch biosynthesis were pre-maturely activated in the osbzip76 caryopsis.As a putative transcription factor,OsbZIP76 alone lacked transcriptional activation activity;however,it interacted with the nuclear factor Y(NF-Y)family transcription factors OsNF-YB9 and OsNF-YB1 in yeast and in planta.OsbZIP76 and OsNF-YB9 were predominantly expressed in the endosperm and the proteins colocalized.Seeds of osnf-yb1 and osbzip76 mu-tants showed reduced size and reduced apparent amylose content.The parent-of-origin-dependent expression of OsbZIP76 is variable in different rice accessions.In sum-mary,OsbZIP76 is an endosperm-expressed imprinted gene that regulates endosperm development in rice.
