| 4 | Prevalence of Autism Spectrum Disorder in China:A Nationwide Multi-center Population-based Study Among Children Aged 6 to 12 Years显示文摘This study aimed to obtain the first national estimate of the prevalence of autism spectrum disorder(ASD) in Chinese children.We targeted the population of 6 to 12-year-old children for this prevalence study by multistage convenient cluster sampling.The Modified Chinese Autism Spectrum Rating Scale was used for the screening process.Of the target population of 142,086 children,88.5%(n=125,806) participated in the study.A total of 363 children were confirmed as having ASD.The observed ASD prevalence rate was 0.29%(95% CI:0.26%-0.32%) for the overall population.After adjustment for response rates,the estimated number of ASD cases was867 in the target population sample,thereby achieving an estimated prevalence of 0.70%(95% CI:0.64%-0.74%).The prevalence was significantly higher in boys than in girls(0.95%;95% CI:0.87%-1.02% versus 0.30%;95%CI:0.26%-0.34%;P <0.001).Of the 363 confirmed ASD cases,43.3% were newly diagnosed,and most of those(90.4%) were attending regular schools,and 68.8% of the children with ASD had at least one neuropsychiatric comorbidity.Our findings provide reliable data on the estimated ASD prevalence and comorbidities in Chinese children. | Hao Zhou Xiu Xu Weili Yan Xiaobing Zou Lijie Wu Xuerong Luo Tingyu Li Yi Huang Hongyan Guan Xiang Chen Meng Mao Kun Xia Lan Zhang Erzhen Li Xiaoling Ge Lili Zhang Chunpei Li Xudong Zhang Yuanfeng Zhou Ding Ding Andy Shih Eric Fombonne Yi Zheng Jisheng Han Zhongsheng Sun Yong-hui Jiang Yi Wang LATENT-NHC Study Team | 2020 | Neuroscience Bulletin2020,36,9: | 158 |
| 5 | PTEN encoding product:a marker for tumorigenesis and progression of gastric carcinoma显示文摘AIM: To detect the expression of PTEN encoding productin normal mucosa, intestinal metaplasia (IM), dysplasia andcarcinoma of the stomach, and to investigate its clinicalimplication in tumorigenesis and progression of gastriccarcinoma.METHODS: Formalin-fixed paraffin embedded specimens from184 cases of gastric carcinoma, their adjacent normal mucosa,IM and dysplasia were evaluated for PTEN protein expressionby SABC immunohistochemistry. PTEN expression wascompared with tumor stage, lymph node metastasis, Lauren'sand WHO's histological classification of gastric carcinoma.Expression of VEGF was also detected in 60 cases of gastriccarcinoma and its correlation with PTEN was concerned.RESULTS: The positive rates of PTEN protein were 100 %(102/102), 98.5 %(65/66), 66.7 % (4/6) and 47.8 %(88/184)in normal mucosa, IM, dysplasia and carcinoma of the stomach,respectively. The positive rates in dysplasia and carcinomawere lower than in normal mucosa and IM (P<0.01).Advanced gastric cancers expressed less frequent PTEN thanearly gastric cancer (42.9 % v567.6 %, P<0.01). The positiverate of PTEN protein was lower in gastric cancer with thanwithout lymph node metastasis (40.3 % v563.3 %, P<0.01).PTEN was less expressed in diffuse-type than in intestinal-type gastric cancer (41.5 % v557.8 %,P<0.05). Signet ringcell carcinoma showed the expression of PTEN at the lowestlevel (25.0 %, 7/28); less than well and moderatelydifferentiated ones (P<0.01). Expression of PTEN was notcorrelated with expression of VEGF (P>0.05).CONCLUSION: Loss or reduced expression of PTEN proteinoccures commonly in tumorigenesis and progression of gastriccarcinoma. It is suggested that PTEN can be an objective markerfor pathologically biological behaviors of gastric carcinoma. | Lin Yang Li-Ge Kuang Hua-Chuan Zheng Jin-Yi Li Dong-Ying Wu Su-Min Zhang Yan Xin No.4 Lab,Cancer Institute,The First Affiliated Hospital,China Medical University,Shenyang 110001,China Ying Chen Shen Yang Gynecology & Obstetrics Hospital,Shenyang 110014,China | 2003 | World Journal of Gastroenterology2003,9,1: | 127 |

| 7 | Trends of incidence rate and age at diagnosis for cervical cancer in China,from 2000 to 2014显示文摘Objective: To analyze the trends of incidence rate and age at diagnosis for cervical cancer incidence in China using population-based cancer registration data from 2000 to 2014.Methods: Data were from National Central Cancer Registry of China.Crude incidence rates(CIRs),age-specific incidence rate,age-standardized incidence rates(ASIRs),age percentage distribution,standardized age percentage distribution,mean age at diagnosis and standardized mean age at diagnosis for cervical cancer in all areas of China,urban China and rural China were calculated separately.The world Segi's population was applied to remove the age structure influence.Joinpoint regression was performed to obtain average annual percent change(AAPC) and ageperiod-cohort analysis was used to examine the incidence trends.Results: CIRs and ASIRs for cervical cancer increased in China from 2000 to 2014.The AAPC of ASIRs in China was at 9.2% [95% confidence interval(95% CI): 7.0%–11.5%,P<0.05],and the AAPC in rural areas was relatively high.The age-specific incidence rate in groups aged 0–69 years have significantly increased over time.Groups aged 40–69 years showed the highest incidence risk,and the annual percent changes(APCs) of incidence rate in groups aged 40–59 years in urban China and groups aged 0–49 years in rural China were more than 10%.For each age group,the urban-to-rural incidence rate ratios(IRRs) got close to 1 over time.There were clear birth cohort effects in successive generations born from 1940 to 1970 in China.In rural China,the standardized mean age at diagnosis had significantly declined by 5.18 years.In China,the main peak and secondary peak of standardized age percentages appeared in the groups aged 45–49 and 40–44 years,respectively.In rural China,the main peak of standardized age percentage moved from the group aged 55–59 years to the group aged 45–49 years,and the standardized age percentages of groups aged 25–34 years also increased.In China,the standardized age percentages has significantly increased in groups aged 35–64 and 30–64 years over time,and accounted for about80% and 85% in 2014,respectively.Conclusions: The cervical cancer incidence increased in China and the gap of incidence between urban and rural China was narrowed.The trends of increasing cervical cancer incidence among younger women existed in China,especially in rural China.A more appropriate screening,vaccination and health education strategies should be established. | Xueting Li Rongshou Zheng Xuemei Li Haibin Shah Qi Wu Yan Wang Wanqing Chen | 2017 | Chinese Journal of Cancer Research2017,29,6: | 64 |
| 8 | Identification of a novel HMW glutenin subunit and comparison of its amino acid sequence with those of homologous subunits显示文摘Aegilops tauschii is the donor of the D genome of common wheat (Triticum aestivum). Genetic variation of HMW glutenin subunits encoded by the Glu-1Dt locus of Ae. tauschii has been found to be higher than that specified by the Glu-1D locus in common wheat. In the present note, we report the identification of a novel HMW glutenin subunit, Dy13t, from Ae. tauschii. The newly identified subunit pos-sessed an electrophoretic mobility that was faster than that of the Dy12 subunit of common wheat. The complete ORF of encoding the Dy13t subunit contained 624 codons (excluding the stop codons). The amino acid sequence deduced from the Dy13t gene ORF was the shortest among those of the previ-ously reported subunits derived by the D genome. A further comparison of Dy13t amino acid sequence with those of the subunits characterized from the A, B, D, R genomes of Triticeae showed that the smaller size of the Dy13t subunit was associated with a reduction in the size of its repetitive domain. | YAN Zehong WAN Yongfang LIU Kunfan ZHENG Youliang WANG Daowen | 2002 | Chinese Science Bulletin2002,47,3: | 60 |
| 9 | Diagnosis, treatment, and prevention of 2019 novel coronavirus infection in children: experts' consensus statement显示文摘Since the outbreak of 2019 novel coronavirus infection (2019-nCoV) in Wuhan City,China,by January 30,2020,a total of 9692 confirmed cases and 15,238 suspected cases have been reported around 31 provinces or cities in China.Among the confirmed cases,1527 were severe cases,171 had recovered and been discharged at home,and 213 died.And among these cases,a total of 28 children aged from 1 month to 17 years have been reported in China.For standardizing prevention and management of 2019-nCoV infections in children,we called up an experts' committee to formulate this experts' consensus statement.This statement is based on the Novel Coronavirus Infection Pneumonia Diagnosis and Treatment Standards (the fourth edition) (National Health Committee) and other previous diagnosis and treatment strategies for pediatric virus infections.The present consensus statement summarizes current strategies on diagnosis,treatment,and prevention of 2019-nCoV infection in children. | Kunling Shen Yonghong Yang Tianyou Wang Dongchi Zhao Yi Jiang Runming Jin Yuejie Zheng Baoping Xu Zhengde Xie Likai Lin Yunxiao Shang Xiaoxia Lu Sainan Shu Yan Bai Jikui Deng Min Lu Leping Ye Xuefeng Wang Yongyan Wang Liwei Gao | 2020 | World Journal of Pediatrics2020,16,3: | 56 |
| 10 | Roux-en-Y choledochojejunostomy using novel magnetic compressive anastomats in canine model of obstructive jaundice显示文摘BACKGROUND:The traditional hand-sewn Roux-en-Y choledochojejunostomy is technically complicated,and the incidence of postoperative complications has remained high.A set of novel magnetic compressive anastomats was introduced to facilitate choledochojejunostomy and improve the prognosis of patients.METHODS:After ligating the common bile duct for 7 days,16 dogs were randomly divided into two groups (n=8 per group).Anastomats were used in the study group,and the traditional hand-sewn method was used in the control group for standard Roux-en-Y choledochojejunostomy.We compared the operation time,incidence of complications,gross appearance,and pathological disparity in stoma between the two groups in 1-month and 3-month follow-up examinations.RESULTS:The time spent on constructing the anastomosis for the study group was significantly shortened.Although no anastomotic stenosis occurred in the two groups,the narrowing rate of biliary-enteric anastomosis was much higher in the control group.There was one case of bile leakage in the control group,whereas no bile leakage occurred in the study group.A smoother surface,an improved layer apposition,and a lower local inflammatory response were identified in the anastomosis of the study group.CONCLUSION:The structures of the novel magnetic compressive anastomats are simple,and they are time-saving,safe and efficient for performing Roux-en-Y choledocho- jejunostomy procedures in a canine model of obstructive jaundice. | Chao Fan,Xiao-Peng Yan,Shi-Qi Liu,Chun-Bao Wang,Jian-Hui Li,Liang Yu,Zheng Wu and Yi Lv Department of Hepatobiliary Surgery and Department of Pathology,First Affiliated Hospital,School of Medicine,Xi’an Jiaotong University,Xi’an 710061,China Department of Surgical Oncology,Third Affiliated Hospital,School of Medicine,Xi’an Jiaotong University,Xi’an 710068,China | 2012 | Hepatobiliary & Pancreatic Diseases International2012,11,1: | 49 |

| 13 | Effect of mild moxibustion on intestinal microbiota and NLRP6 inflammasome signaling in rats with post-inflammatory irritable bowel syndrome显示文摘BACKGROUND About one-third of refractory irritable bowel syndrome(IBS)cases are caused by gastrointestinal(GI)infection/inflammation,known as post-infectious/postinflammatory IBS(PI-IBS).Although it is known that intestinal microbiota and host NOD-like receptor family pyrin domain containing 6(NLRP6)inflammsome signaling are closely related to PI-IBS and moxibustion has a therapeutic effect on PI-IBS,whether moxibustion regulates the intestinal flora and host NLRP6 events in PI-IBS remains unclear.AIM To examine the regulatory effect of moxibustion on intestinal microbiota and host NLRP6 inflammatory signaling in PI-IBS.METHODS Sprague-Dawley rats were divided into a normal control group,a model control group,a mild moxibustion group,and a sham mild moxibustion group.PI-IBS rats in the mild moxibustion group were treated with moxibusiton at bilateral Tianshu(ST 25)and Zusanli(ST36)for 7 consecutive days for 10 min each time.The sham group rats were given the same treatment as the mild moxibustion group except the moxa stick was not ignited.Abdominal withdrawal reflex(AWR)score was measured to assess the visceral sensitivity,and colon histopathology and ultrastructure,colonic myeloperoxidase(MPO)activity,and serum C-reactive protein(CRP)level were measured to evaluate low-grade colonic inflammation in rats.The relative abundance of selected intestinal bacteria in rat feces was detected by 16S rDNA PCR and the NLRP6 inflammsome signaling in the colon was detected by immunofluorescence,qRTPCR,and Western blot.RESULTS The AWR score was significantly decreased and the low-grade intestinal inflammation reflected by serum CRP and colonic MPO levels was inhibited in the mild moxibustion group compared with the sham group.Mild moxibustion remarkably increased the relative DNA abundances of Lactobacillus,Bifidobacterium,and Faecalibacterium prausnitzii but decreased that of Escherichia coli in the gut of PI-IBS rats.Additionally,mild moxibustion induced mRNA and protein expression of intestine lectin 1 but inhibited the expression of IL-1β,IL-18,and resistance-like moleculeβby promoting the NLRP6 and reducing the mRNA and protein expression of apoptosis-associated speck-like protein containing CARD(ASC)and cysteinyl-aspartate-specific proteinase 1(Caspase-1).The relative DNA abundances of Lactobacillus,Bifidobacteria,Faecalibacterium prausnitzii,and Escherichia coli in each group were correlated with the mRNA and protein expression of NLRP6,ASC,and Caspase-1 in the colon.CONCLUSION These findings indicated that mild moxibustion can relieve low-grade GI inflammation and alleviate visceral hypersensitivity in PI-IBS by regulating intestinal microbes and controlling NLRP6 inflammasome signaling. | Chun-Hui Bao Chun-Ye Wang Guo-Na Li Yi-Lu Yan Di Wang Xiao-Ming Jin Lu-Yi Wu Hui-Rong Liu Xiao-Mei Wang Zheng Shi Huan-Gan Wu | 2019 | World Journal of Gastroenterology2019,25,32: | 45 |
| 14 | Relationship between phenotypes of cell-function differentiation and pathobiological behavior of gastric carcinomas显示文摘AIM To reveal the correlation between thefunctional differentiation phenotypes of gastriccarcinoma cells and the invasion and metastasisby a new way of cell-function classification.METHODS Surgically resected specimens of361 gastric carcinomas (GC) were investigatedwith enzyme-, mucin-, and tumor-related markerimmunohistochemist ry. According to thedirection of cell-function differentiation,stomach carcinomas were divided into fivefunctionally differentiated types.iation type (AFDT): there were 82 (22.7%)patients including 76 (92.7%) aged 45 years.Sixty-nine (84.1%) cases belonged to theintestinal type. Thirty-eight (46.3%) expressedCD44v6 and 9 (13.6%) of 66 male patientsdeveloped liver metastasis. The 5-year survivalrate of patients in this group (58.5%) was higherMucin secreting function differentiation type(MSFDT): 54 (15%) cases. Fifty-three (98.1%)tumors had penetrated the serosa, 12 (22.2%)expressed ER and 22 (40.7%) expressedCD44v6. The postoperative 5-year survival ratefunction differentiation type (AMPFDT): therewere 180 (49.9%) cases, including 31 (17.2%)aged yanger than 45 years. The tumor was morecommon in women (62, 34.4%,) and expressedmore frequently estrogen receptors (ER) ( 129,81.7%) than other types (P<0.01). Ovarymetastasis was found in 12 (19.4%) out of 62female subjects. The patients with this type GChad the lowest 5-year survival rate (24.7%)differentiation type (SFDT): 13 (3.6%) cases.Nine (69.2%) tumors of this type derived fromAPUD system, the other 4 (30.7%) were ofdifferent histological differentiation. Sixty percent of the patients survived at least five years.(8.9%) cases. Nineteen (59.4%) cases hadlymph node metastases but no one with liver orovary metastasis. The 5-year survival rate was28.1%.CONCLUSION This new cell-functionclassification of GC is helpful in indicating thecharacteristics of invasion and metastasis of GCwith different cell-function differentiationphenotypes. Further study is needed to disclosethe correlation between the cell-functionaldifferentiation phenotypes and the relevantgenotypes and the biological behavior of gastriccarcinoma. | Yan Xin Xiao Ling Li Yan Ping Wang Su Min Zhang Hua Chuan Zheng Dong Ying Wu Yin Chang Zhang The Fourth Laboratory of Cancer Institute, China Medical University, Shenyang 110001, Liaoning Province, China | 2001 | World Journal of Gastroenterology2001,7,1: | 38 |
| 15 | Millennial temperature reconstruction based on tree-ring widths of Qilian juniper from Wulan,Qinghai Province,China显示文摘The climate of the past 1000 years is an important context for evaluating the recent climate warming.However,there are few 1000-year-long climate reconstructions with annual resolution in the Qing-hai-Tibet Plateau.In this paper,a dendroclimatic analysis was conducted for the radial growth of Qilian juniper from the upper forest limit in Wulan,Qinghai Province.The results of correlation analysis between the tree-ring widths and the climate variables indicate that the growth of junipers at the upper forest limit is mainly limited by low temperatures of September,November and February of the pregrowth season,and July of the current growth season.There is no significant correlation between the tree-ring widths and precipitation.A mean temperature from the previous year's September to the current year's April was reconstructed for the Wulan area since A.D.1000.The reconstruction can explain 40.8% of the instrumental variance in the calibration period(1856―2002).The reconstruction shows that the 20th century is the warmest 100 years,and the 1990s is the warmest decade during the past 1000 years,while the coldest 100 years and decade occur at 1600―1699 and 1642―1651,respectively.The variations are verified well by the temperature reconstruction of the middle Qilian Mountain(QL) and the total organic carbon(TOC) in the Qinghai Lake sediments.The comparison of our reconstruction with the annual temperature reconstruction of extra-tropical Northern Hemisphere suggests that the climate of Wulan during the Medieval Warm Period is of obvious regional specialty,but there was a good response to the climate of hemispheric scales during the recent 400 years. | ZHU HaiFeng ZHENG YongHong SHAO XueMei LIU XiaoHong XU Yan LIANG ErYuan | 2008 | Chinese Science Bulletin2008,53,24: | 40 |

| 18 | Urinary trypsin inhibitor attenuates hepatic ischemia-reperfusion injury by reducing nuclear factor-kappa B activation显示文摘BACKGROUND:Urinary trypsin inhibitor(UTI)inhibits the inflammatory response and protects against ischemia- reperfusion(I/R)injury.The inflammatory response is mediated by nuclear factor-kappa B(NF-κB)and its related target genes and products such as vascular endothelial cell adhesion molecule and CXC chemokines.We aimed to assess the roles of those mediators in a UTI-treated mouse model of hepatic I/R injury. METHODS:Treatment group 1(UTI given 5 minutes prior to liver ischemia),treatment group 2(UTI given 5 minutes after the anhepatic phase)and a control group were investigated.Blood and liver samples were obtained and compared at 1,3,6 and 24 hours after reperfusion. RESULTS:Attenuation of pathological hepatocellular damage was greater in the treatment groups than in the control group(P<0.05).Compared with the control group, the UTI treatment groups showed significantly lower serum alanine aminotransferase and aspartate aminotransferase levels,decreased myeloperoxidase activity,and reduced NF- κB activation.Also downregulated was the expression of tumor necrosis factor-alpha,cytokine-induced neutrophil chemoattractant,and macrophage inflammatory protein-2 at the mRNA level.P-selectin protein and intercellular adhesion molecule-1 protein expression were also downregulated.In addition,the treatment group 1 showed a better protective effect against I/R injury than the treatment group 2.CONCLUSIONS:UTI reduces NF-κB activation and downregulates the expression of its related mediators, followed by the inhibition of neutrophil aggregation and infiltration in hepatic I/R injury.The protective role of UTI is more effective in prevention than in treatment. | Wu, Yi-Jun Ling, Qi Zhou, Xin-Hui Wang, Yan Xie, Hai-Yang Yu, Ji-Ren Zheng, Shu-Sen | 2009 | Hepatobiliary & Pancreatic Diseases International2009,8,1: | 28 |
| 19 | The General Design and Technology Innovations of CAP1400显示文摘行波堆为一次通过式燃料循环反应堆,其利用堆芯自增殖大大降低了对浓缩和后处理的需求。自增殖将次临界换料燃料转化为新的临界燃料,从而使增殖燃烧波得以扩散。该理念建立在增殖燃烧波和燃料的相对移动的基础上。因此,燃料或增殖燃烧波相对于固定的观察器而言是移动的。行波堆最实用的体现就是能够在将核反应保持在同一位置的同时移动燃料——有时行波堆也被称为'驻波堆'。行波堆能够使用换料铀燃料运行,换料铀燃料包括完全贫化铀、天然铀和低浓缩铀燃料(即235U含量为5.5%或更低的燃料),这些燃料通常在快谱中达不到临界状态。轻水反应堆卸出的乏燃料也可以作为行波堆的换料燃料。上述情况均无需后处理即可实现极高的燃料利用率和燃料废物量的显著降低。当换料燃料为贫化铀时,行波堆的最大优势得以实现,即在启动后,无需浓缩设施,就可维持最先启动的反应堆和一连串后续的反应堆的运行。自2006年起,泰拉能源公司(Terra Power)与50多个机构高度协作,开展了概念设计、工程设计和相关技术开发活动,力争到2026年实现将第一个机组投入使用。本文总结了行波堆技术,包括它的发展计划及其进展,分析了行波堆的社会和经济效益。 | Mingguang Zheng Jinquan Yan Jun Shenttu Lin Tian Xujia Wang Zhongming Qiu | 2016 | Engineering2016,2,1: | 27 |
| 20 | Rapid changes of microsatellite flanking sequence in the allopolyploidization of new synthesized hexaploid wheat显示文摘It was suggested that the rapid changes of DNA sequence and gene expression oc- curred at the early stages of allopolyploid formation. In this study, we revealed the microsatellite (SSR) differences between newly formed allopolyploids and their donor parents by using 21 primer sets specific for D genome of wheat. It was indicated that rapid changes had occurred in the “shock” process of the allopolyploid formation between tetraploid wheat and Aegilops tauschii. The changes of SSR flanking sequence resulted in appearance of novel bands or disappearance of parental bands. The disappearance of the parental bands showed much higher frequencies in comparison with that of appearance of novel bands. Disappearance of the parental bands was not random. The frequency of disappearance in tetraploid wheat was much higher than in Ae. tauschii, i. e. the disappearance frequency in AABB genome was much higher than in D genome. Changes of SSR flanking sequence occurred at the early stage of F1 hybrid or just after chro- mosome doubling. From the above results, it can be inferred that SSR flanking sequence region was very active and was amenable to change in the process of polyploidization. This suggested that SSR flanking sequence probably had special biological function at the early stage of ploy- ploidization. The rapid and directional changes at the early stage of polyploidization might con- tribute to the rapid evolution of the newly formed allopolyploid and allow the divergent genomes to act in harmony. | ZHANG Lianquan LIU Dengcai YAN Zehong LAN Xiujin ZHENG Youliang ZHOU Yonghong | 2004 | Science China(Life Sciences)2004,47,6: | 25 |
