| 1 | Indoor Allergen Levels and Household Distributions in Nine Cities Across China显示文摘Objective Chinese allergic subjects have high levels of sensitization to house dust mite(HDM) and other indoor allergens. This study quantifies common indoor allergen levels in Chinese households. Methods Dust samples were collected from nine cities. Major allergens Der p 1 and Der f 1 from Dermatophagoides pteronyssinus and D. farinae, and specific antigens of Blomia tropicalis, Tyrophagus putrescentiae, Acarus siro, and cockroach species Blattella germanica and Periplaneta americana were measured by ELISA. Results HDM allergens were found in dust samples from bedding in 95% of the Chinese households. The median levels varied from <0.006 to 9.2 μg/g of dust, depending on the city. The percentages of households having HDM allergen levels associated with the risk of developing allergy sensitization and asthma were 65% and 25%, respectively. Specific antigens of the storage mite and cockroach were only found in samples from the southern and tropical regions of China. Levels of mite allergens were generally higher in samples from bedding compared to samples from the living room, even for storage mites, whereas levels of cockroach antigens were higher in the living room samples. Conclusion HDM allergens are present in bedding dust samples from most Chinese households. Cities in southern and central China have relatively high levels of HDM major allergens compared to cities in northern and western China. Antigens of storage mites and cockroaches are not as common as HDM allergens. | ZHENG Yi Wu LAI Xu Xin ZHAO De Yu ZHANG Chun Qing CHEN Jian Jun ZHANG Luo WEI Qing Yu CHEN Shi LIU En Mei NORBACK Dan GJESING Birgitte ZHONG Nan Shan SPANGFORT D.Michael | 2015 | Biomedical and Environmental Sciences2015，28，10： | 24 |
| 2 | Typical atmospheric haze during crop harvest season in northeastern China:A case in the Changchun region显示文摘This study presents the mass concentrations of PM_(2.5),O_3,SO_2 and NOxat one urban,one suburban and two rural locations in the Changchun region from September 25 to October 272013. Major chemical components of PM_(2.5)at the four sites were daily sampled and analyzed. Most of daily concentrations of SO_2(7–82 μg/m^3),O_3(27–171 μg/m^3) and NOx(14–213 μg/m^3) were below the limits of the National Ambient Air Quality Standard(NAAQS)in China. However,PM_(2.5)concentrations(143–168 μg/m^3) were 2-fold higher than NAAQS.Higher PM_(2.5)concentrations(~ 150 μg/m^3) were measured during the pre-harvest and harvest at the urban site,while PM_(2.5)concentrations significantly increased from 250 to400 μg m^(-3) at suburban and rural sites with widespread biomass burning. At all sites,PM_(2.5)components were dominated by organic carbon(OC) and followed by soluble component sulfate(SO_4^(2-)),ammonium(NH_4^+) and nitrate(NO_3^-). Compared with rural sites,urban site had a higher mineral contribution and lower potassium(K^+and K) contribution to PM_(2.5).Severe atmospheric haze events that occurred from October 21 to 23 were attributed to strong source emissions(e.g.,biomass burning) and unfavorable air diffusion conditions.Furthermore,coal burning originating from winter heating supply beginning on October 18 increased the atmospheric pollutant emissions. For entire crop harvest period,the Positive Matrix Factorization(PMF) analysis indicated five important emission contributors in the Changchun region,as follows: secondary aerosol(39%),biomass burning(20%),supply heating(18%),soil/road dust(14%) and traffic(9%). | Wei Wei Chen Daniel Q.Tong Mo Dan Shi Chun Zhang Xue Lei Zhang Yue Peng Pan | 2017 | Journal of Environmental Sciences2017，29，4： | 10 |
| 3 | Generation of GGTA1 biallelic knockout pigs via zinc-finger nucleases and somatic cell nuclear transfer显示文摘Genetically modified pigs are valuable models of human disease and donors of xenotransplanted organs.Conventional gene targeting in pig somatic cells is extremely inefficient.Zinc-finger nuclease(ZFN)technology has been shown to be a powerful tool for efficiently inducing mutations in the genome.However,ZFN-mediated targeting in pigs has rarely been achieved.Here,we used ZFNs to knock out the porcineα-1,3-galactosyl-transferase(GGTA1)gene,which generates Gal epitopes that trigger hyperacute immune rejection in pig-to-human transplantation.Primary pig fibroblasts were transfected with ZFNs targeting the coding region of GGTA1.Eighteen mono-allelic and four biallelic knockout cell clones were obtained after drug selection with efficiencies of 23.4%and 5.2%,respectively.The biallelic cells were used to produce cloned pigs via somatic cell nuclear transfer(SCNT).Three GGTA1 null piglets were born,and one knockout primary fibroblast cell line was established from a cloned fetus.Gal epitopes on GGTA1 null pig cells were completely eliminated from the cell membrane.Functionally,GGTA1 knockout cells were protected from complement-mediated immune attacks when incubated with human serum.This study demonstrated that ZFN is an efficient tool in creating gene-modified pigs.GGTA1 null pigs and GGTA1 null fetal fibroblasts would benefit research and pig-to-human transplantation. | BAO Lei CHEN HaiDe JONG UiMyong RIM CholHo LI WenLing LIN XiJuan ZHANG Dan LUO Qiong CUI Chun HUANG HeFeng ZHANG Yan XIAO Lei FU ZhiXin | 2014 | Science China(Life Sciences)2014，57，2： | 9 |
| 4 | Effect of co-transfection of miR-520c-3p and miR-132 on proliferation and apoptosis of hepatocellular carcinoma Huh7显示文摘Objective:To investigate the effects of co-transfection of miR-520c-3p and miR-132 on proliferation and apoptosis of hepatocellular carcinoma Huh7.Methods:Hepatocellular carcinoma Huh7 was cultured in vitro and lipidosome was used to transfect miR-520c-3p and miR-132 respectively or together.The effects of transfection of miR-520c-3p and miR-132 on proliferation and apoptosis of Huh7 were detected by CCK8 and Annexin V staining and flow cytometry,and the expression level of the targeted gene of over-expressed miR-520c-3p and miR-132 was determined by Western blot and realtime PCR.Results:Compared with the control group,the proliferation ability of Huh7 of the single transfected and co-transfected miR-520c-3p and miR-132 decreased significantly,and the apoptosis ratio increased distinctly(P<0.05).Besides,the affect of the co-transfection group was better than that of the single transfection group.The protein levels of GPC3(Glypican-3) and YAP(Yes-associated protein),the target genes transfected only by miR-520c-3p and miR-132,respectively,reduced obviously(P<0.05),which was similar with the co-infected cells,but cells transfected by miR-132 only showed a decrease of YAP.Conclusions:The co-transfection of miR-520c-3p and miR-132 can target-regulate the expression of GPC3 and YAP,enhance the exhibition effect on proliferation of hepatocellular carcinoma Huh7 and induce cell apoptosis synergistically. | Chang-Jiang Lei Chun Yao De-Ke Li Zhi-Xiong Long Yuan Li Dan Tao Yan-Ping Liou Jiang-Zhou Zhang Ning Liu | 2016 | Asian Pacific Journal of Tropical Medicine2016，9，9： | 9 |

| 6 | Development and Validation of a Model for Predicting Diabetic Nephropathy in Chinese People显示文摘Objective To develop a risk model for predicting later development of diabetic nephropathy(DN)in Chinese people with type 2 diabetes mellitus(T2DM)and evaluate its performance with independent validation.Methods We used data collected from the project‘Comprehensive Research on the Prevention and Control of Diabetes’,which was a community-based study conducted by the Jiangsu Center for Disease Control and Prevention in 2013.A total of 11,771 eligible participants were included in our study.The endpoint was a clear diagnosis of DN.Data was divided into two components:a training set for model development and a test set for validation.The Cox proportional hazard regression was used for survival analysis in men and women.The model’s performance was evaluated by discrimination and calibration.Results The incidence(cases per 10,000 person-years)of DN was 9.95(95%CI;8.66-11.43)in women and 11.28(95%CI;9.77-13.03)in men.Factors including diagnosis age,location,body mass index,high-density-lipoprotein cholesterol,creatinine,hypertension,dyslipidemia,retinopathy,diet control,and physical activity were significant in the final model.The model showed high discrimination and good calibration.Conclusion The risk model for predicting DN in people with T2DM can be used in clinical practice for improving the quality of risk management and intervention. | MIAO Dan Dan PAN En Chun ZHANG Qin SUN Zhong Ming QIN Yu WU Ming | 2017 | Biomedical and Environmental Sciences2017，30，2： | 8 |
| 7 | Polymorphism in the upstream regulatory region of human papilloma virus type 16 from the cervical cancer biopsies in Xinjiang Uygur women显示文摘To investigate the mutations in the upstream regulatory region (URR) of human papillomavirus type 16 (HPV-16) from the cervical cancer biopsies in Xinjiang Uygur women and its relationship to the high incidence of cervical cancer in the southern Xinjiang, the tissue DNA was extracted from the cervical cancer biopsies, and the URR segment of HPV-16 DNA was amplified, sequenced and analyzed. Thereafter, the polymorphism of URR in HPV-16 was then analyzed. It was demonstrated that the positive rate detected for the presence of URR in HPV-16 was 89.47% (17/19). Compared with the previously published sequence in URR of prototype HPV-16, some mutations were detected in the sequence of URR. The mutations in 17 URR fragments of HPV-16 could be divided into 11 patterns (XJU-1 to XJU-11) at nucleic acid level, in which each of XJU-1 and XJU-4 accounted for 23.53% (4/17), and other patterns of mutation accounted for 5.88% (1/17) . In comparison with the URR of prototype HPV-16, the DNA identity of these patterns was 98.50%-99.68% . In these 17 URR fragments, two point mutations occurred at position 7192 (G to T) and position 7520 (G to A) and they appeared to be constant in Xinjiang area. These two mutations were ubiquitous in the Asia-American type and conferred strong infection activity and carcinogenicity of this virus. In addition, the mutations at position 7729 (A to C), position 7843 (A to G) and position 7792 (C to T) could enhance its transcription activity considerably. It is concluded that some mutations occur in URR gene of HPV-16 in the cervical cancer biopsies taken from Uygur women in Xinjiang area, suggesting that certain relationship exists among the mutations in URR of HPV-16, the phylogeny of HPV-16 and the high incidence of cervical cancer in southern part of Xinjiang area. | MENG YU ZHENG HAI MA YAN PIN WANG XI DAN RE FU CHUN ZHANG | 2006 | Journal of Microbiology and Immunology2006，4，3： | 4 |

| 13 | Diagnosis,treatment,and prevention of severe acute hepatitis of unknown etiology in children显示文摘Background Severe acute hepatitis of unknown etiology in children has recently exhibited a global trend of concentrated occurrence.This review aimed to summarize the current available information regarding the outbreak of severe acute hepatitis and introduce our hospital’s previous experiences with the diagnosis and treatment of severe acute hepatitis for reference.Data sources Websites including the UK Health Security Agency,European Centre for Disease Prevention and Control,CDC,WHO,and databases including PubMed/Medline,Cochrane Library,Embase and Web of Science were searched for articles on severe acute hepatitis in children.Results As of May 26,2022,a total of 650 cases have been reported in 33 countries;at least 38(6%)children required liver transplantation,and nine(1%)died.Cases are predominantly aged between 3 and 5 years old,and there are no epidemiological links among them.The common manifestations are jaundice,vomiting and pale stools.Adenovirus tested positive in most cases,and SARS-CoV-2 and other viruses were detected in a few cases,but virus particles were not found in liver tissue.Adenovirus immunohistochemistry showed immunoreactivity in the intrasinusoidal lumen from some liver samples.The hierarchical treatment includes symptomatic and supportive therapy,management of coagulation disorders and hepatic encephalopathy,artifcial liver support,and liver transplantation(approximately 6%–10%of cases require liver transplant).Conclusions The etiology of this severe acute hepatitis in children is not clear.The clinical features are severe acute hepatitis with signifcantly elevated liver enzymes.Clinicians need to be alert to children with hepatitis. | Ying‑Hu Chen Jin‑Gan Lou Zi‑Hao Yang Qing‑Jiang Chen Chun‑Zhen Hua Sheng Ye Chen‑Mei Zhang Jie Chen Zong‑Wei Huang Jin‑Dan Yu Zhi‑Gang Gao Qiang Shu | 2022 | World Journal of Pediatrics2022，18，8： | 2 |
| 14 | Kinetic Characteristics of Neutralizing Antibody Responses Vary among Patients with COVID-19显示文摘Objective The coronavirus disease 2019(COVID-19) pandemic continues to present a major challenge to public health. Vaccine development requires an understanding of the kinetics of neutralizing antibody(NAb) responses to severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).Methods In total, 605 serum samples from 125 COVID-19 patients(from January 1 to March 14, 2020)varying in age, sex, severity of symptoms, and presence of underlying diseases were collected, and antibody titers were measured using a micro-neutralization assay with wild-type SARS-CoV-2.Results NAbs were detectable approximately 10 days post-onset(dpo) of symptoms and peaked at approximately 20 dpo. The NAb levels were slightly higher in young males and severe cases, while no significant difference was observed for the other classifications. In follow-up cases, the NAb titer had increased or stabilized in 18 cases, whereas it had decreased in 26 cases, and in one case NAbs were undetectable at the end of our observation. Although a decreasing trend in NAb titer was observed in many cases, the NAb level was generally still protective.Conclusion We demonstrated that NAb levels vary among all categories of COVID-19 patients. Longterm studies are needed to determine the longevity and protective efficiency of NAbs induced by SARS-CoV-2. | LI Ling Hua TU Hong Wei LIANG Dan WEN Chun Yan LI An An LIN Wei Yin HU Ke Qi HONG Wen Shan LI Yue Ping SU Juan ZHAO San Tao LI Wei YUAN Run Yu ZHOU Ping Ping HU Feng Yu TANG Xiao Ping KE Chang Wen KE Bi Xia CAI Wei Ping | 2021 | Biomedical and Environmental Sciences2021，34，12： | 1 |
