7Using specific secondary metabolites as markers to evaluate allelopathic potentials of rice varieties and individual plants显示文摘It is a key of the breeding of ailelopathic rice cultivars to evaluate and screen few accessions with ailelopathic traits from numerous rice accessions and individual plants. Rice varieties and individual plants with ailelopathic traits demonstrated their ailelopathic effects by producing and releasing specific secondary metabolites into environment. Therefore, using specific secondary metabolites as markers, the ailelopathic potentials of rice varieties and individual plants could be evaluated by HPLC. The ailelopathic potentials of 3000 rice accessions and some individual plants of F3 and F4 were evaluated by this method in 1 a. If these accessions and plants were evaluated by the traditional method in the field, it would take more than 10 a, furthermore, the breeding process of ailelopathic rice cultivars would be directed and monitored by this method. Isolation and structural identification of specific secondary metabolites was done by LC/MS coupling 1H and 13C NMR. It revealed that allelochemicalsKONG Chuihua XU Xiaohua HU Fei CHEN Xionghui LING Bing TAN Zhongwen 2002Chinese Science Bulletin2002,47,10:17
8Potassium dehydroandrographolide succinate injection for treatment of infantile pneumonia:a systematic review and Meta-analysis显示文摘OBJECTIVE:To evaluate systematically the clinical efficacy and safety of potassium dehydroandrographolide succinate injection(PDS) in treatment of infantile pneumonia.METHODS:Randomized controlled trials(RCTs) of infantile pneumonia treated by PDS were searched in China National Knowledge Infrastructure Database,China Science and Technology Journal Database,Wanfang Database,Chinese Biomedical Literature Database,PubMed,and Cochrane Library,from January 1979 to July 2013.Two reviewers independently retrieved the RCTs and extracted the information.The quality of included studies was assessed by the Cochrane risk of bias,and a Meta-analysis was conducted with Review Manager 5.2 software.RESULTS:A total of 9 studies with 1056 participants were included.The quality of the studies was generally no high,only one study mentioned the random method.The Meta-analysis indicated that PDS was significantly superior to the conventional therapy in the total effective rate[relative risk(RR)=1.21,95%CI(1.14,1.27),P<0.000 01],the time of temperature recovery[mean difference(MD)=-1.43,95%CI(-1.75,-1.11),P<0.000 01],rale disappeared and cough relieving[MD=-1.44,95%CI(-1.93,-0.90),P<0.000 01].Six adverse drug reactions from five studies mainly represented rash and diarrhea,and no serious ADRs were reported.CONCLUSION:Based on this systematic review,PDS was proved effective and relatively safe in treatment of infantile pneumonia.However the articles enrolled in the study were not high in quality,studies with higher quality should be conducted for assessment of efficacy and safety of PDS in treatment of infantile pneumonia.Zhang Xiaomeng Wu Jiarui Zhang Bing Dong Ling 2015Journal of Traditional Chinese Medicine2015,35,2:17

10Key residues of the receptor binding motif in the spike protein of SARS-CoV-2 that interact with ACE2 and neutralizing antibodies显示文摘Coronavirus disease 2019(COVID-19),caused by the novel human coronavirus SARS-CoV-2,is currently a major threat to public health worldwide.The viral spike protein binds the host receptor angiotensin-converting enzyme 2(ACE2)via the receptor-binding domain(RBD),and thus is believed to be a major target to block viral entry.Both SARS-CoV-2 and SARS-CoV share this mechanism.Here we functionally analyzed the key amino acid residues located within receptor binding motif of RBD that may interact with human ACE2 and available neutralizing antibodies.The in vivo experiments showed that immunization with either the SARS-CoV RBD or SARS-CoV-2 RBD was able to induce strong clade-specific neutralizing antibodies in mice;however,the cross-neutralizing activity was much weaker,indicating that there are distinct antigenic features in the RBDs of the two viruses.This finding was confirmed with the available neutralizing monoclonal antibodies against SARS-CoV or SARS-CoV-2.It is worth noting that a newly developed SARS-CoV-2 human antibody,HA001,was able to neutralize SARS-CoV-2,but failed to recognize SARS-CoV.Moreover,the potential epitope residues of HA001 were identified as A475 and F486 in the SARS-CoV-2 RBD,representing new binding sites for neutralizing antibodies.Overall,our study has revealed the presence of different key epitopes between SARS-CoV and SARSCoV-2,which indicates the necessity to develop new prophylactic vaccine and antibody drugs for specific control of the COVID-19 pandemic although the available agents obtained from the SARS-CoV study are unneglectable.Chunyan Yi Xiaoyu Sun Jing Ye Longfei Ding Meiqin Liu Zhuo Yang Xiao Lu Yaguang Zhang Liyang Ma Wangpeng Gu Aidong Qu Jianqing Xu Zhengli Shi Zhiyang Ling Bing Sun 2020Cellular & Molecular Immunology2020,17,6:13
11Epidemiological Data of Work-Related Musculoskeletal Disorders—China,2018–2020显示文摘Summary What is already known about this topic?In recent decades,work-related musculoskeletal disorders(WMSDs)have become increasingly prominent and have become an important issue that is of universal concern and an urgent need to be solved in all countries of the world.What is added by this report?The top three industries or occupational groups with the highest standardized prevalence rate of WMSDs were flight attendants,medical staff,and vegetable greenhouses in that order.Women workers were 1.5 times more likely to suffer from WMSDs than men workers.Ning Jia Huadong Zhang Ruijie Ling Yimin Liu Gang Li Zaoliang Ren Yan Yin Hua Shao Hengdong Zhang Bing Qiu Meibian Zhang Dayu Wang Qiang Zeng Rugang Wang Jianchao Chen Danying Zhang Liangying Mei Yongquan Liu Jixiang Liu Chengyun Zhang Tianlai Li Qing Xu Ying Qu Xueyan Zhang Xin Sun Zhongxu Wang 2021China CDC weekly2021,3,18:13
12Individualized Chemotherapy in Advanced NSCLC Patients Based on mRNA Levels of BRCA1 and RRM1显示文摘Objective: Experimental evidence suggests that the overexpression of breast cancer-specific tumor suppressor protein 1 (BRCA1) gene enhances sensitivity to docetaxel and resistance to cisplatin and ribonucleotide reductase M1 (RRM1) gene overexpression enhances resistance to gemcitabine. To further examine the effect of BRCA1 and RRM1 mRNA levels on outcome in advanced non-small cell lung cancer (NSCLC), we performed this non-randomized phase II clinical trial which tested the hypothesis that customized therapy would confer improved outcome over non-customized therapy. Methods: RNA was isolated from fresh tumor tissue. Patients received chemotherapy regimen based on their BRCA1 and RRM1 mRNA levels: both low-cisplatin plus gemcitabine (GP); both high-vinorelbine plus cisplatin (NP); BRCA1 low and RRM1 high-cisplatin plus docetaxel (TP); BRCA1 high and RRM1 low-vinorelbine plus gemcitabine (GN). Results: From Dec 2005 to Nov 2008, 94 metastatic and locally advanced NSCLC patients from our institute were enrolled in this study. The median age was 58 years old. Among them, 21 patients received GP, 30 patients received TP and 43 patients received NP chemotherapy. GP group had a higher response rate, and longer median time to progression (TTP) and median overall survival (OS) time than the other 2 groups. The response rates in the GP, TP and NP groups were 42.9%, 36.7% and 27.9%, respectively (P=0.568). The median TTP was 5.6, 5.0, 4.8 months (P=0.975), respectively, and the median OS time was 12.5, 11.0, 9.7 months (P=0.808), respectively. Conclusion: Chemotherapy customized according to BRCA1 and RRM1 expression levels is associated with higher response rate and longer TTP and OS time in the GP group. This suggests that BRCA1 and RRM1 mRNA levels could be used as biomarkers in individual therapy in NSCLC.Sheng-xiang Ren Ai-wu Li Song-wen Zhou Ling Zhang Yong-sheng Wang Bing Li Xiao-xia Chen Jie Zhan Jian-fang Xu Cai-cun Zhou 2012Chinese Journal of Cancer Research2012,24,3:12
13Clinical application of simultaneous detection of cystatin C,cathepsin S,and IL-1 in classification of coronary artery disease显示文摘Cystatin C,cathepsin S,and IL-1 are three important biomarkers of atherosclerosis.Previous studies emphasized the relationship between individual biomarkers in coronary artery disease(CAD) patients and severity of atherosclerostic lesions of the coronary arteries,while combined cystatin C,cathepsin S,and IL-1 have not been reported for clinical classification of CAD.We aimed to establish a link between cystatin C,cathepsin S,IL-1 and CAD in this cohort study.Totally 112 subjects were enrolled and divided into the stable angina pectoris group,the unstable angina pectoris group and the acute myocardial infarction(AMI) groups,and 50 healthy adults served as controls.The levels of the three biomarkers were detected by ELISA.The results showed that serum level of cystatin C(mg/L) was higher in CAD patients compared with those in the healthy controls(AMI vs.unstable angina pectoris vs.stable angina pectoris vs.controls:1.27±0.18 vs.1.09±0.19 vs.0.91±0.05 vs.0.78±0.07,all P<0.01).Cathepsin S(ng/mL) was also significantly different among the groups(AMI vs.unstable angina pectoris vs.stable angina pectoris vs.controls:67.30±8.36 vs.56.90±7.16 vs.49.8±2.72 vs.67.30±8.36,all P<0.01).IL-1(pg/mL) was significantly different among the groups as well(AMI vs.unstable angina pectoris vs.stable angina pectoris vs.controls:2.96±0.57 vs.2.46±0.24 vs.2.28±0.09 vs.2.02±0.13,all P<0.01).Spearman's correlation test revealed positive correlation between cystatin C,cathepsin S,IL-1 and Gensini score(r=0.451,0.491,0.397,respectively).It is suggested that simultaneous detection of cystatin C,cathepsin S,and IL-1 in serum may be useful in clinical classification and assessment of severity of CAD.Ling Yan Shuang Ding Bing Gu Ping Ma 2017The Journal of Biomedical Research2017,31,4:12
14Investigation on Work-Related Musculoskeletal Disorders--China, 2018−2019显示文摘What is already known about this topic?Work-related musculoskeletal disorders(WMSDs)have a high prevalence and seriously harmful,which has attracted extensive attention in various countries in the world.Currently,the occurrence and rules of WMSDs in key industries are not known in China.What is added by this report?The prevalence of WMSDs is relatively high among professional populations in key industries in China,with the most commonly affected body parts concentrated in neck,shoulders,and low back and increasing with age and working years.What are the implications for public health practice?This study determined the prevalence and distribution characteristics of WMSDs in key industries in China and provided scientific evidence to recommend for inclusion of WMSDs in the new revision of the list of occupational diseases in China.Ning Jia Huadong Zhang Ruijie Ling Yimin Liu Gang Li Zaoliang Ren Yan Yin Hua Shao Hengdong Zhang Bing Qiu Meibian Zhang Dayu Wang Qiang Zeng Rugang Wang Jianchao Chen Danying Zhang Liangying Mei Yongquan Liu Jixiang Liu Chengyun Zhang Tianlai Li Qing Xu Ying Qu Xueyan Zhang Xin Sun Zhongxu Wang 2020China CDC weekly2020,2,18:11
15Differentiation of embryonic stem cells into corneal epithelium显示文摘Our project was to determine whether embryonic stem (ES) cells could be induced to differentiate into corneal epithelia by superficial corneoscleral limbal stroma. To achieve this goal, ES-GFP cell line D3 was pre-induced by retinoic acid (RA). The pre-induced cells were seeded on deepithelialized superficial corneoscleral slices (SCSS) to form a monolayer, and di-vided into three groups. Group 1 was cultured and passaged in vitro for direct detection. Group 2 was exposed to air-liquid interfaces for 10 days and implanted into the subcutaneous layer of nude mice for 2 weeks for further induction in vivo. Group 3 was cultured in vitro without any in-ducing factors for control. There were no teratomas found in nude mice which were implanted with differentiated ES cells after two weeks. The differentiated cells showed an appearance of epithelia both in vitro and in vivo. Expression of CK3, P63 and PCNA was detected by immuno-histochemical staining in the differentiated cells in group 1 and 2. Microvillis and zonula oc-cludens were observed on the surface of the differentiated cells under an electron microscope. In the control group, ES cells differentiated freely without any inducing factors. Most cells were shed and formed a neuronal dendrite-like structure, and a minority of cells appeared polymorphic. These results demonstrate that ES cells can differentiate into corneal epithelia on the surface of SCSS under the controlled condition. Differentiated ES cells could be used as epithelial seeding cells for the reconstruction of ocular surface and corneal tissue engineering in the future.WANG Zhichong GE Jian HUANG Bing GAO Qianying LIU Bingqian WANG Linghua YU Ling FAN Zhigang LU Xiaoming LIU Jingbo 2005Science China(Life Sciences)2005,48,5:10
16Comparison of basic features and origins of oolitic shoal reservoirs between carbonate platform interior and platform margin locations in the Lower Triassic Feixianguan Formation of the Sichuan Basin,southwest China显示文摘The oolitic shoal reservoirs of the Lower Triassic Feixianguan Formation carbonates in the Sichuan Basin of southwest China are an important target for gas exploration in the basin.Their occurrence,like other cases worldwide,can be divided into two locations in general,i.e.,platform interior and platform margin locations.Their differences of reservoir features and origins,however,have not been investigated comprehensively due to different exploration degrees.This issue is addressed in this paper,to provide basic data and information for the basin's hydrocarbon exploration and for the study of carbonate platform sedimentology and reservoir geology worldwide.We compared the features of these two types of reservoirs in detail,including the depositional and diagenetic features,pore types and petrophysical features.Based on the comparison,the origin of the reservoirs was further discussed.It is shown that the reservoirs in platform interior and platform margin locations differ significantly.The interior carbonates were deposited in moderate to high energy settings and the dominant lithologic type was limestone,which was weakly compacted and intensely cemented and has undergone meteoric dissolution.Pore types include intragranular dissolution and moldic pores,with low porosities(<6%) and low permeabilities(<0.1 mD).By contrast,the platform margin carbonates were deposited in relatively high energy settings and mainly consisted of dolostones with some limestones.The rocks were strongly compacted but incompletely cemented.As a result,some primary intergranular pores were preserved.Both meteoric solution and burial solution have taken place.There are various types of pore spaces including intergranular and intercrystalline solution pores and residual intergranular pores.This type of reservoir generally has better petrophysical properties(>9% porosity and >0.1 mD permeability) and pore-throat structures than the interior reservoirs.These differences were influenced by both primary depositional features and secondary diagenesis.For the interior carbonate reservoirs,early meteoric dissolution,weak compaction and strong cementation are important controlling factors.By contrast,the factors controlling the formation of the margin carbonate reservoirs mainly include dolomitization,preservation of primary pores and burial dissolution.Tan Xiucheng Zhao Luzi Luo Bing Jiang Xingfu Cao Jian Liu Hong Li Ling Wu Xingbo Nie Yong 2012Petroleum Science2012,9,4:9
17Identify the signature genes for diagnose of uveal melanoma by weight gene co-expression network analysis显示文摘AIM: To identify and understand the relationship between co-expression pattern and clinic traits in uveal melanoma, weighted gene co-expression network analysis(WGCNA) is applied to investigate the gene expression levels and patient clinic features. Uveal melanoma is the most common primary eye tumor in adults. Although many studies have identified some important genes and pathways that were relevant to progress of uveal melanoma, the relationship between co-expression and clinic traits in systems level of uveal melanoma is unclear yet. We employ WGCNA to investigate the relationship underlying molecular and phenotype in this study.METHODS: Gene expression profile of uveal melanoma and patient clinic traits were collected from the Gene Expression Omnibus(GEO) database. The gene co-expression is calculated by WGCNA that is the R package software. The package is used to analyze the correlation between pairs of expression levels of genes.The function of the genes were annotated by gene ontology(GO).RESULTS: In this study, we identified four co-expression modules significantly correlated with clinictraits. Module blue positively correlated with radiotherapy treatment. Module purple positively correlates with tumor location(sclera) and negatively correlates with patient age. Module red positively correlates with sclera and negatively correlates with thickness of tumor. Module black positively correlates with the largest tumor diameter(LTD). Additionally, we identified the hug gene(top connectivity with other genes) in each module. The hub gene RPS15 A, PTGDS, CD53 and MSI2 might play a vital role in progress of uveal melanoma.CONCLUSION: From WGCNA analysis and hub gene calculation, we identified RPS15 A, PTGDS, CD53 and MSI2 might be target or diagnosis for uveal melanoma.Kai Shi Zhi-Tong Bing Gui-Qun Cao Ling Guo Ya-Na Cao Hai-Ou Jiang Mei-Xia Zhang 2015International Journal of Ophthalmology(English edition)2015,8,2:9
18Subtyping Animal Influenza Virus with General Multiplex RT-PCR and Liquichip High Throughput (GMPLex)显示文摘This study developed a multiplex RT-PCR integrated with luminex technology to rapidly subtype simultaneously multiple influenza viruses. Primers and probes were designed to amplify NS and M genes of influenza A viruses HA gene of H1, H3, H5, H7, H9 subtypes, and NA gene of the N1 and N2 subtypes. Universal super primers were introduced to establish a multiplex RT-PCR (GM RT-PCR). It included three stages of RT-PCR amplification, and then the RT-PCR products were further tested by LiquiChip probe, combined to give an influenza virus (IV) rapid high throughput subtyping test, designated as GMPLex. The IV GMPLex rapid high throughput subtyping test presents the following features: high throughput, able to determine the subtypes of 9 target genes in H1, H3, H5, H7, H9, N1, and N2 subtypes of the influenza A virus at one time; rapid, completing the influenza subtyping within 6 hours; high specificity, ensured the specificity of the different subtypes by using two nested degenerate primers and one probe, no cross reaction occurring between the subtypes, no non-specific reactions with other pathogens and high sensitivity. When used separately to detect the product of single GM RT-PCR for single H5 or N1 gene, the GMPLex test showed a sensitivity of 10-5(= 280ELD50) forboth tests and the Luminex qualitative ratio results were 3.08 and 3.12, respectively. When used to detect the product of GM RT-PCR for H5N1 strain at the same time, both showed a sensitivity of 10-4(=2800 ELD50).

20The Ability of Baseline Triglycerides and Total Cholesterol Concentrations to Predict Incidence of Type 2 Diabetes Mellitus in Chinese Men and Women:A Longitudinal Study in Qingdao, China显示文摘Objectives The purpose of this study was to assess the association between triglycerides(TG),total cholesterol(TC)at baseline,and type 2 diabetes mellitus(T2DM)incidence in a general Chinese population.Further,it aimed to evaluate the ability of TG and TC to predict T2DM incidence.Methods Qingdao Diabetes Prevention Program participants recruited between 2006 and 2009 were followed up in 2012–2015.TG,TC,and T2DM status were measured.Cox proportional hazards models were used to estimate the association between TG,TC,and T2DM incidence.The receiver operating characteristic(ROC)curve was used to evaluate the ability of TG and TC to identify T2DM participants.Results The incidence of T2DM significantly increased with TG in women and TC in both men and women(Ptrend<0.05).Univariate Cox regression indicated that higher TG{borderline high TG[hazards ratio(HR):2.05;95%confidence interval(CI):1.40,3.00]and hypertriglyceridemia[HR:2.64;95%CI:1.68,4.15]}and TC[hypercholesterolemia(HR:2.05;95%CI:1.43,2.95)]were significantly associated with increased risk of T2DM incidence in women but not in men.Multivariate Cox regression showed that hypertriglyceridemia in women(HR:1.78,95%CI:1.07,2.97),borderline high TC in men(HR:1.61,95%CI:1.04,2.48),and hypercholesterolemia in women(HR:1.68,95%CI:1.81,2.61)had a higher significant risk of T2DM incidence.The optimal cutoff values of TG were>1.15 and>1.23 mmol/L in men and women,respectively.For TC,they were>5.17 and>5.77 mmol/L in men and women,respectively.The area under the ROCs of TG and TC were 0.54(0.51–0.57)and 0.55(0.52–0.58),respectively,in men,and 0.60(0.58–0.62)and 0.59(0.56–0.61),respectively,in women.Conclusion Elevated TG and TC were risk factors for T2DM incidence.However,no predictive capacity was found for both factors to identify T2DM incidence in Chinese men and women.Hence,TG and TC levels in both Chinese men and women might be used for decreasing the incidence of T2DM but no clinical predictive capacity for T2DM.CUI Jing MA Ping SUN Jian Ping Zulqamain Baloch YIN Fan XIN Hua Lei REN Jie TAN Ji Bin WANG Bing Ling 2019Biomedical and Environmental Sciences2019,32,12:7
