3Analysis of Allergens in 5473 Patients with Allergic Diseases in Harbin, China显示文摘Objective To analyze the allergic status to common inhalant allergens and food allergens in clinical patients in Harbin in northeastern China and provide evidence to develop the prevention strategy of allergic disease. Methods The data were collected from 5473 patients with clinical suspected allergic diseases seeking medical care in the Second Affiliated Hospital of Harbin Medical University. Among these patients, 2530(46.2%) were males aged 0-86 years, the youngest was only 1 month old and 2579(47.1%) were young children and teenagers. The serum specific Immunoglobulin E(sIgE) to 14 kinds of common allergens and serum total IgE were detected by using AllergyScreen test(Mediwiss Analytic GmbH, Moers, Germany). Results In 5473 subjects the positive rate of sIgE was 33.1%(n=1813). Cow milk(6.9%) and wheat(3.1%) were the most common food allergens, followed by house dust mite mix(12.5%) and mould mix(9.4%) and the age and gender specific differences in the positive rate were significant. For the children aged <7 years the positive rates to cow milk, beef-mutton, and egg white/egg yolk were high, but the positive rates to house dust mite mix, ragweed estragon, and mould mix were low(P<0.05). For the adults the positive rates to aeroallergens were high while the rates to food allergens were low. Conclusion The results from this study showed that the food allergens in Harbin had geographic characteristics, which support the viewpoint that the environment factors play an important role in the incidence of allergic diseases. Also, the detection of sIgE and total IgE are essential to identify relevant allergens for the purpose of early diagnosis, management and prevention of allergic disease.CHANG Man Li SHAO Bing LIU Yan Hong LI Lu Lu PEI Li Chun WANG Bin You 2013Biomedical and Environmental Sciences2013,26,11:11

5Effect of temperature on the sorption and desorption of perfluorooctane sulfonate on humic acid显示文摘Sorption and desorption of perfluorooctane sulfonate (PFOS) on humic acid at different temperatures were studied. It was found that the sorption process could be modeled with power kinetic equation very well, suggesting that diflusion predominated the sorption of PFOS on the humic acid. The sorption capacity was doubled when the temperature increased from 5 to 35°C, and thermodynamics parameters △G0 was calculated to be -7.11 to -5.04 kJ/mol, △H0 was 14.2 kJ/mol, and △S 0 was 69.5 J/(mol·K), indicating that the sorption was a spontaneous, endothermic, and entropy driven process. Desorption hysteresis occurred at all studied temperatures which suggested that humic acid may be an important sink of PFOS in the environment.Chengxia Jia, Chun You, Gang Pan State Key Laboratory of Environmental Aquatic Chemistry, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, Beijing 100085, China. 2010Journal of Environmental Sciences2010,22,3:10

7Outcome of transarterial chemoembolization-based multi-modal treatment in patients with unresectable hepatocellular carcinoma显示文摘AIM:To investigate the efficacy and safety of transarterial chemoembolization(TACE)-based multimodal treatment in patients with large hepatocellular carcinoma(HCC).METHODS:A total of 146 consecutive patients were included in the analysis,and their medical records and radiological data were reviewed retrospectively.RESULTS:In total,119 patients received TACE-based multi-modal treatments,and the remaining 27 received conservative management.Overall survival(P<0.001)and objective tumor response(P=0.003)were significantly better in the treatment group than in the conservative group.After subgroup analysis,survival benefits were observed not only in the multi-modal treatment group compared with the TACE-only group(P=0.002)but also in the surgical treatment group compared with the loco-regional treatment-only group(P<0.001).Multivariate analysis identified tumor stage(P<0.001)and tumor type(P=0.009)as two independent pre-treatment factors for survival.After adjusting for significant pre-treatment prognostic factors,objective response(P<0.001),surgical treatment(P=0.009),and multi-modal treatment(P=0.002)were identified as independent post-treatment prognostic factors.CONCLUSION:TACE-based multi-modal treatments were safe and more beneficial than conservative management.Salvage surgery after successful downstaging resultedin long-term survival in patients with large,unresectable HCC.Do Seon Song Soon Woo Nam Si Hyun Bae Jin Dong Kim Jeong Won Jang Myeong Jun Song Sung Won Lee Hee Yeon Kim Young Joon Lee Ho Jong Chun Young Kyoung You Jong Young Choi Seung Kew Yoon 2015World Journal of Gastroenterology2015,21,8:7
8An Evaluation of the Investment for Child Development in China显示文摘Objective This study estimated the investment in child development from three aspects-public health,public education,and family investment to establish the level of investment,to provide reference information for government decision making and to provide international comparisons.Methods Public investment in health was measured with macro data related to public health spending and child development in government expenditure.Public education investment was based on basic education data.Family investment evaluation was based on per capita family consumer spending data in different age groups to estimate the input for child development.Results Both public health investment level and the proportion of GDP rose for all age groups over time,but the overall investment level was still insufficient.Public investment in children's education has increased year by year,but the trends in all age groups are unbalanced with much lower investment in early childhood education.Private investment in children has increased over the period,but has declined as a percentage of GDP.International comparisons show that China's investment in child development is much lower than OECD countries.Conclusion The private investment in child development was the main way in China,with public finance contributing only a small proportion.Given the poor international comparisons,the government needs to review the balance of public investment to redirect more towards the development of children under the age of six to their health and education.ZHENG Xiao Ying CHEN Chun Ming HUANG Cheng Li Han You Li QIU Yue ZHANG Qian Deng CHEN He 2012Biomedical and Environmental Sciences2012,25,4:4

10Quality control and evaluation of human immunodeficiency virus antibody assays used for screening donated blood in China显示文摘During 2004, a total of 124 batches of HIV antibody ELISAs from domestic and overseas manufacturers, comprising approximately 60 million tests, were tested for quality and released for screening blood in China. The inter- and intra-batch variation, specificity, and sensitivity were evaluated using a laboratory panel and clinical samples. The inter-batch variation was less than 15% and only 2 of 12 assays had intra-batch variation of less than 20% for 4 dilutions of a control specimen. 257 samples confirmed positive for HIV antibody and 4826 negative samples from different regions in China were used to evaluate the sensitivity and specificity of the assays. The results showed that the sensitivity is in the range from 93.7% to 100% for assays sampled directly from the manufacturers, and 91. 4%-99. 6% for those retrieved from the consumers; the specificity was in the range from 97.88% to 99.97% . The testing environment may vary in different regions of China. Therefore, manufacturers should provide robust assays to satisfy the requirements of these diverse environments, and especially reduce the intra-assay variation and improve the stability of the kits.You CHUN WANG XIU HUA LI AI JING SONG CHUN TAO ZHANG SI HONG XU FENG ZHANG HONG ZHANG YIN 2006Journal of Microbiology and Immunology2006,4,1:4
11The FAST Galactic Plane Pulsar Snapshot survey:I.Project design and pulsar discoveries显示文摘Discovery of pulsars is one of the main goals for large radio telescopes.The Five-hundredmeter Aperture Spherical radio Telescope(FAST),that incorporates an L-band 19-beam receiver with a system temperature of about 20 K,is the most sensitive radio telescope utilized for discovering pulsars.We designed the snapshot observation mode for a FAST key science project,the Galactic Plane Pulsar Snapshot(GPPS)survey,in which every four nearby pointings can observe a cover of a sky patch of 0.1575 square degrees through beam-switching of the L-band 19-beam receiver.The integration time for each pointing is 300 seconds so that the GPPS observations for a cover can be made in 21 minutes.The goal of the GPPS survey is to discover pulsars within the Galactic latitude of±10∘from the Galactic plane,and the highest priority is given to the inner Galaxy within±5∘.Up to now,the GPPS survey has discovered 201 pulsars,including currently the faintest pulsars which cannot be detected by other telescopes,pulsars with extremely high dispersion measures(DMs)which challenge the currently widely used models for the Galactic electron density distribution,pulsars coincident with supernova remnants,40 millisecond pulsars,16 binary pulsars,some nulling and mode-changing pulsars and rotating radio transients(RRATs).The follow-up observations for confirmation of new pulsars have polarization-signals recorded for polarization profiles of the pulsars.Re-detection of previously known pulsars in the survey data also leads to significant improvements in parameters for 64 pulsars.The GPPS survey discoveries are published and will be updated at http://gffzz656c80eee53645cchbpc6ofnp6ppn69uu.ffgz.tsg.suse.edu.cn/GPPS/.J.L.Han Chen Wang P.F.Wang Tao Wang D.J.Zhou Jing-Hai Sun Yi Yan Wei-Qi Su Wei-Cong Jing Xue Chen X.Y.Gao Li-Gang Hou Jun Xu K.J.Lee Na Wang Peng Jiang Ren-Xin Xu Jun Yan Heng-Qian Gan Xin Guan Wen-Jun Huang Jin-Chen Jiang Hui Li Yun-Peng Men Chun Sun Bo-Jun Wang H.G.Wang Shuang-Qiang Wang Jin-Tao Xie Heng Xu Rui Yao Xiao-Peng You D.J.Yu Jian-Ping Yuan Rai Yuen Chun-Feng Zhang Yan Zhu 2021Research in Astronomy and Astrophysics2021,21,5:4

16Processing Environmental Stimuli in Paranoid Schizophrenia:Recognizing Facial Emotions and Performing Executive Functions显示文摘Objective To study the contribution of executive function to abnormal recognition of facial expressions of emotion in schizophrenia patients. Methods Abnormal recognition of facial expressions of emotion was assayed according to Japanese and Caucasian facial expressions of emotion (JACFEE), Wisconsin card sorting test (WCST), positive and negative symptom scale, and Hamilton anxiety and depression scale, respectively, in 88 paranoid schizophrenia patients and 75 healthy volunteers. Results Patients scored higher on the Positive and Negative Symptom Scale and the Hamilton Anxiety and Depression Scales, displayed lower JACFEE recognition accuracies and poorer WCST performances. The JACFEE recognition accuracy of contempt and disgust was negatively correlated with the negative symptom scale score while the recognition accuracy of fear was positively with the positive symptom scale score and the recognition accuracy of surprise was negatively with the general psychopathology score in patients. Moreover, the WCST could predict the JACFEE recognition accuracy of contempt, disgust, and sadness in patients, and the perseverative errors negatively predicted the recognition accuracy of sadness in healthy volunteers. The JACFEE recognition accuracy of sadness could predict the WCST categories in paranoid schizophrenia patients. Conclusion Recognition accuracy of social-/moral emotions, such as contempt, disgust and sadness is related to the executive function in paranoid schizophrenia patients, especially when regarding sadness.YU Shao Hua ZHU Jun Peng XU You ZHENG Lei Lei CHAI Hao HE Wei LIU Wei Bo LI Hui Chun WANG Wei 2012Biomedical and Environmental Sciences2012,25,6:3
17Conversion of D-glucose to L-lactate via pyruvate by an optimized cell-free enzymatic biosystem containing minimized reactions显示文摘Cell-free synthetic enzymatic biosystem is emerging to expand the traditional biotechnological mode by utilizing a number of purified/partially purified enzymes and coenzymes in a single reaction vessel for the production of desired products from low-cost substrates.Here,a cell-free synthetic biosystem containing minimized number of reactions was designed for the conversion of D-glucose to L-lactate via pyruvate.This NADH-balanced biosystem was comprised of only 5 thermophilic enzymes without ATP supplementation.After optimization of enzyme loading amounts,buffer concentration and cofactor concentration,D-glucose was converted to L-lactate with a product yield of∼90%.Our study has provided an emerging platform with potentials in producing pyruvatederived chemicals,and may promote the development of cell-free synthetic enzymatic biosystems for biomanufacturing.Leipeng Xie Xinlei Wei Xigui Zhou Dongdong Meng Ruimin Zhou Yi-Heng P.Job Zhang Shuxia Xu Chun You 2018Synthetic and Systems Biotechnology2018,3,3:3
18Comparative study of rendezvous techniques in post-liver transplant biliary stricture显示文摘AIM:To investigate the usefulness of a new rendezvous technique for placing stents using the Kumpe(KMP) catheter in angulated or twisted biliary strictures.METHODS:The rendezvous technique was performed in patients with a biliary stricture after living donor liver transplantation(LDLT) who required the exchange of percutaneous transhepatic biliary drainage catheters for inside stents.The rendezvous technique was performed using a guidewire in 19 patients(guidewire group) and using a KMP catheter in another 19(KMP catheter group).We compared the two groups retrospectively.RESULTS:The baseline characteristics did not differ between the groups.The success rate for placing inside stents was 100% in both groups.A KMP catheter was easier to manipulate than a guidewire.The mean procedure time in the KMP catheter group(1012 s,range:301-2006 s) was shorter than that in the guidewire group(2037 s,range:251-6758 s,P = 0.022).The cumulative probabilities corresponding to the procedure time of the two groups were significantly different(P = 0.008).The factors related to procedure time were the rendezvous technique method,the number of inside stents,the operator,and balloon dilation of the stricture(P < 0.05).In a multivariate analysis,the rendezvous technique method was the only significant factor related to procedure time(P = 0.010).The procedural complications observed included one case of mild acute pancreatitis and one case of acute cholangitis in the guidewire group,and two cases of mild acute pancreatitis in the KMP catheter group.CONCLUSION:The rendezvous technique involving use of the KMP catheter was a fast and safe method for placing inside stents in patients with LDLT biliary stricture that represents a viable alternative to the guidewire rendezvous technique.Jae Hyuck Chang In Seok Lee Ho Jong Chun Jong Young Choi Seung Kyoo Yoon Dong Goo Kim Young Kyoung You Myung-Gyu Choi Sok Won Han 2012World Journal of Gastroenterology2012,18,41:3
19Sex Differences in Diagnosis and Clinical Phenotypes of Chinese Children with Autism Spectrum Disorder显示文摘The aim of this study was to explore the differences between boys and girls in the diagnosis and clinical phenotypes of autism spectrum disorder(ASD) in China's mainland. Children diagnosed with ASD(n = 1064, 228 females) were retrospectively included in the analysis. All children were assessed using the Autism Diagnostic Interview-Revised(ADI-R) and Autism Diagnostic Observation Schedule(ADOS). The results showed that girls scored significantly higher in ADI-R socioemotional reciprocity than boys, and also scored lower in ADI-R and ADOS restricted and repetitive behaviors(RRBs). Meanwhile, the proportions of girls who satisfied the diagnostic cut-off scores in the ADI-R RRBs domain were lower than in boys(P \ 0.05). Our results indicated that girls with ASD show greater socio-emotional reciprocity than boys. Girls also tended to show fewer RRBs than boys, and the type of RRBs in girls differ from those in boys. The ADI-R was found to be less sensitive in girls, particularly for assessment in the RRBs domain.Shihuan Wang Hongzhu Deng Cong You Kaiyun Chen Jianying Li Chun Tang Chaoqun Ceng Yuanyuan Zou Xiaobing Zou 2017Neuroscience Bulletin2017,33,2:3
