| 2 | Long-term bone and lung consequences associated with hospital-acquired severe acute respiratory syndrome:a 15-year follow-up from a prospective cohort study显示文摘The most severe sequelae after rehabilitation from SARS are femoral head necrosis and pulmonary fibrosis. We performed a 15-year follow-up on the lung and bone conditions of SARS patients. We evaluated the recovery from lung damage and femoral head necrosis in an observational cohort study of SARS patients using pulmonary CT scans, hip joint MRI examinations, pulmonary function tests and hip joint function questionnaires. Eighty medical staff contracted SARS in 2003. Two patients died of SARS, and78 were enrolled in this study from August 2003 to March 2018. Seventy-one patients completed the 15-year follow-up. The percentage of pulmonary lesions on CT scans diminished from 2003(9.40 ± 7.83)% to 2004(3.20 ± 4.78)%(P < 0.001) and remained stable thereafter until 2018(4.60 ± 6.37)%. Between 2006 and 2018, the proportion of patients with interstitial changes who had improved pulmonary function was lower than that of patients without lesions, as demonstrated by the one-second ratio(FEV1/FVC%, t = 2.21, P = 0.04) and mid-flow of maximum expiration(FEF25%–75%, t = 2.76, P = 0.01). The volume of femoral head necrosis decreased significantly from 2003(38.83 ± 21.01)% to 2005(30.38 ± 20.23)%(P = 0.000 2), then declined slowly from 2005 to 2013(28.99 ± 20.59)% and plateaued until 2018(25.52 ± 15.51)%. Pulmonary interstitial damage and functional decline caused by SARS mostly recovered, with a greater extent of recovery within 2 years after rehabilitation. Femoral head necrosis induced by large doses of steroid pulse therapy in SARS patients was not progressive and was partially reversible. | Peixun Zhang Jia Li Huixin Liu Na Han Jiabao Ju Yuhui Kou Lei Chen Mengxi Jiang Feng Pan Yali Zheng Zhancheng Gao Baoguo Jiang | 2020 | Bone Research2020,8,1: | 8 |
| 3 | Recurrent deletions in the SARS-CoV-2 spike glycoprotein drive antibody escape显示文摘Zoonotic pandemics,like that caused by SARS-CoV-2,can follow the spillover of animal viruses into highly susceptible human populations.Their descendants have adapted to the human host and evolved to evade immune pressure.Coronaviruses acquire substitutions more slowly than other RNA viruses,due to a proofreading polymerase.In the spike glycoprotein,we find recurrent deletions overcome this slow substitution rate. | Kevin R McCarthy | 2021 | 四川生理科学杂志2021,43,1: | 6 |

A mild method for introducing BrCF_2 group to organic molecules显示文摘BrCF2SO2Br, prepared from sulfinatodehalogenation of CF2Br2 followed by bromination ofthe intermediate BrCF2SO2Na, was shown to be a mild and efficient bromodifluoromethylating agent. | HUANG, Wei-Yuan ZHANG, Han-Zhong Shanghai Institute of Organic Chemistry, Chinese Academy of Sciences, Shanghai 200032 | 1992 | Chinese Journal of Chemistry1992,10,3: | 3 |
| 5 | Adiabatic Enhanced Compression of Ultrashort Pulses in Fibres with Slowly Decreasing Dispersion显示文摘We investigate the adiabatic enhanced compression of ultrashort pulses from a distributed feedback laser operated at 1550 nm in fibres with slowly decreasing dispersion (FSDD). High-quality pulse compressions from 4.4 ps down to 1.1ps in a l00m FSDD and from 4.4ps down to 830fs in a 500m FSDD are obtained. The Raman self frequency shift of femtosecond pulses in the compression is observed. Theoretical analyses are in good agreement with experimental results. | 徐文成 张书敏 罗爱平 陈伟成 廖常俊 刘颂豪 伍剑 娄采云 高以智 | 2001 | Chinese Physics Letters2001,18,10: | 3 |
| 6 | Inflection point: a perspective on photonic nanojets显示文摘When light propagates through the edge or middle part of a microparticle’s incoming interface,there is a basic rule that light converges and diverges rapidly or slowly at the output port. These two parts are referred to as the region of rapid change (RRC) and region of slow change (RSC),respectively. Finding the boundary point between RRC and RSC is the key to reveal and expound upon this rule scientifically. Based on the correlation between light convergence–divergence and the slope of emergent light,combined with the relationship between a natural logarithm and growth in physical reality and the second derivative of a function in practical significance,we determine the boundary point between RRC and RSC,namely,the inflection point. From such a perspective,a photonic nanojet (PNJ) and near-field focusing by light irradiation on RSC and RRC,as well as the position of the inflection point under different refractive index contrasts and the field distribution of light focusing,are studied with finite-element-method-based numerical simulation and ray-optics-based theoretical analysis. By illuminating light of different field intensity ratios to the regions divided by the inflection point,we demonstrate the generation of a photonic hook (PH) and the modulation of PNJ/PH in a new manner. | GUOQIANG GU PENGCHENG ZHANG SIHUI CHEN YI ZHANG HUI YANG | 2021 | Photonics Research2021,9,7: | 2 |
| 7 | Gain-Scheduled Control and Stability Analysis of Morphing Aircraft in Transition Process显示文摘The large-scale morphing aircraft can change its shape dramatically to perform high flight performance.To ensure the transient stability of aircraft in the morphing process,a novel gain-scheduled control method is investigated numerically in this paper.Based on quasi-steady assumption,the linear parameter varying (LPV) model of the morphing vehicle is derived from its nonlinear equation.Afterwards,by solving a set of linear matrix inequalities along with the bound of the morphing rate via slowly varying system theory,the designed controller which considers the transition stability during the morphing process is obtained.Finally,the transition process simulations of the morphing aircraft are performed via the changes simultaneously in both span and sweep,and the results demonstrate the effectiveness of the proposed controller. | Li Wencheng Jin Dongping | 2018 | Transactions of Nanjing University of Aeronautics and Astronautics2018,35,6: | 2 |
| 8 | THE DIFFERENTIATION OF HUMAN GASTRIC ADENOCAR-CINOMA CELL LINE MGc80-3 INDUCED BY DIBUTYRYL cAMP IN VITRO显示文摘For providing some experimental basis in establishing malignant phenotypic reversed indexes of gastric carcinoma cells, human gastric adenocar-cinoma cell line MGc80-3 was induced by dBcAMP in vitro to appraise the effect of gastric carcinoma cell differentiation by chemical inducers.Under light microscope, MGc80-3 cells, after treated with 1 mM dBcAMP, tended to be flat and disperse, and their volume gradually enlarged, with their uncleus relatively smaller and their shape rather regular. Morphological changes, like norma differentiated epithelial cells, were observed. The cells attached firmly, grew slowly, their growth curve showed inhibitory rate amounted to 52.87%, and cellular division exponent displayed their peak value 1.5 times less than that of MGc80-3 cells. It was clear that dBcAMP could effectively inhibit the multiplication activity of MGc80-3 cells. After dBcAMP treatment, remarkable changes of cell surface charges was indicated by cell electrophoresis, the ratio dropped to 3.043 from 3. | 李祺福 汪德耀 | 1991 | Chinese Journal of Cancer Research1991,3,1: | 2 |
| 9 | Autoimmune polyglandular syndrome type 3 complicated by mineralocorticoid-responsive hyponatremia of the elderly显示文摘We experienced the first case with autoimmune polyglandular syndrome type 3(anti-thyroid peroxidase ant ib ody-positive hypothyroidism and anti-glutamic acid decar boxylase antibody-positive diabetes) complicated by miner alocorticoid-responsive hyponatremia of the elderly.This case is also a rare slowly progressive insulin-dependent diabetes mellitus(SPIDDM) case,for which the patient has been treated for many years with sulfonylurea or glinide.Our observation also demonstrated that glucose metabolism in autoimmune diabetes such as SPIDDM is influenced by appetite,thyroid function and glucocorticoid effect. | Hidekatsu Yanai Seiko Okamoto Junwa Kunimatsu | 2010 | World Journal of Diabetes2010,1,4: | 2 |
| 10 | Air-drying changes the distribution of Hedley phosphorus pools in forest soils显示文摘Hedley labile phosphorus(P)pools in soil tend to be several times larger than annual forest requirements,even in highly weathered soils characterized by P limitation.The discrepancy between plant and soil P status could be partly attributable to the frequently adopted air-drying pretreatment that tends to increase soil P solubility.In this study,the effects of air-drying on the distribution of Hedley P fractions were examined using soils collected under 4 forest types at Gongga Mountain,southwestern China.The results showed that the microbial biomass P(Pmic)in the organic horizon decreased markedly after air-drying.The concentrations of Hedley labile P in the air-dried samples were 31%–73%more than those in the field-moist samples.Consequently,the air-drying-induced increments of Hedley labile P pools in the surface soil horizons were 0.8–3.8 times the annual plant P requirements.The organic horizon was more susceptible to the air-drying-induced increases in Hedley labile P than the mineral horizon,probably because of the stronger release of Pmicand disruption of soil organic matter.The quality of P,indexed by the ratio of Hedley labile P to slowly cycling P,shifted in favor of the Hedley labile fractions after air-drying,further revealing that air-drying changed the distribution of Hedley P pools in forest soils.These indicated that the effects of air-drying could not be ignored when interpreting the discrepancy between the P status of plants and the Hedley labile P pools in forest soils.To more efficiently evaluate the P status in forest soils via the Hedley fractionation procedure,the use of field-moist soils is recommended. | Jipeng WANG Yanhong WU Jun ZHOU Haijian BING Hongyang SUN Ji LUO Shengyan PU | 2020 | Pedosphere2020,30,2: | 1 |
| 11 | STUDY ON THE FORMATION OF BLACK PATINA ON BRONZE MIRRORS INDUCED BY HUMIC ACID显示文摘The black patina on some ancient Chinese bronze mirrors is known as 'Black Lacquer Antique'(BLA) or 'Hei-qi-qu', which looks jet-black and shiny. BLA’s were corroded slowly, one of them was about 10-4mm per year in the soil. Many scholars have studied the composition and structure of BLA, but the formation remains obscure. In this paper the formation of BLA on the surface of bronze mirror samples induced by humic acids under different conditions has been studied. | Zhao Zeng MA* Lian Ji JIN Department of Chemistry, University of Science and Technology Beijing, Beijing 100083 | 1993 | Chinese Chemical Letters1993,4,1: | 1 |

| 13 | The asymptotic distributions of sums of record values for distributions with lognormal-type tails显示文摘Let X1,X2,... be a sequence of i.i.d. random variables and let X(1),X(2),... be the associatedrecord value sequence. We focus on the asymptotic distributions of sums of records, Tn=∑nk=1X(k), forX1 ∈ LN(γ). In this case, we find that 2 is a strange point for parameter γ. When γ> 2, Tn is asymptoticallynormal, while for 2 >γ> 1, we prove that Tn cannot converge in distribution to any non-degenerate lawthrough common centralizing and normalizing and log Tn is asymptotically normal. | 胡治水 苏淳 王定成 | 2002 | Science China Mathematics2002,45,12: | 1 |
| 14 | ON THE SOURCE AND GENESIS OF THE MUD IN THE CENTRAL AREA OF THE SOUTH YELLOW SEA显示文摘Investigations and studies for years all demonstrated that there is a patch of fine-grained mud in the central area of the South Yellow Sea. However, scientists have different opinions on its material source, genesis, and sedimentation intensity. Some believe that the materials come from the Huanghe River, some think that the mud area represents the depocentre of the South Yellow Sea, and some consider it as 'relict mud '. The authors ’ geochemical study reveals that the mud is multi-sourced, yet the material supply is not ample, and that a little amount of fine-grained suspended materials deposited slowly under the dynamic action of a cyclonic gyre formed the modern muddy sediment, which is named 'multi-source modern mud '. | 赵一阳 秦朝阳 李凤业 陈毓蔚 | 1990 | Chinese Journal of Oceanology and Limnology1990,8,1: | 1 |

| 16 | Pair Production in an Intense Laser Pulse: The Effect of Pulse Length显示文摘Production of positron-electron (e^(+) e^(-) ) pairs in an intense laser pulse is investigated by solving the Dirac equation with analytical and numerical methods.We observe that the probability of the pair production will firstly decrease slowly as the pulse length T becomes shortened.Then it will increase until T is reduced to the Compton time Tc =(h)/(mec) ≈ 1.29 × 10^(-21)s and finally decrease exponentially to zero.Hence,for a prominent pair production,we not only require that the electric field strength should be higher than the Schwinger critical value Ecr =m^(2)c^(3)/(e(h)) ≈ 1.32 × 10^(16) V/cm,but also that the pulse duration T should be larger than Tc.The latter is shown to be related to momentum requirement for the transition.For fields with different pulse lengths,the phase and chirp influences upon the pair production are also explored. | 任娜 王加祥 李安康 王平晓 | 2012 | Chinese Physics Letters2012,29,7: | 1 |
| 17 | POSSIBILITY TO USE SCH(?)RDINGER EQUATION TO DESCRIBE LARGE-SCALE PROBABILITY WAVES AND ITS APPLICATION IN SEASONAL PREDICTION显示文摘Under the influence of a one-dimensional stationary outfield with the equilibrium between kinetic andpotential energy produced by it,a modified Sch(?)rdinger equation in the form i((?)ψ/(?)t)t=a (?)~2ψ/ax^2-ib(?),where b=b_o(?)T/(?)x,is used to describe the behavior of the probability wave on the six-monthdeparture charts at the 500 hPa level.It is found that C=2πa/L-b_o(?)T/ax and when L→∞,then C=-b_o(?)T/(?)x,where C is wave velocity,a and b are constants,and L is wavelength.The motion direction ofprobability waves is against the outfield temperature gradient,and their velocity is related to the absolute valueof temperature gradient.The motion of waves shrinks in heat sinks and expands in heat sources,which have beenverified in practice.Finally the six-month departure probability wave and the modified Sch(?)rdinger equationare used in the MOS predictions of temperature and rainfall in spring-summer 1981-1985 in Jilin Province andthe accuracy for trend predictions is equal to 80%. | 章少卿 李麦村 朱其文 | 1989 | Acta meteorologica Sinica1989,3,1: | 1 |
| 18 | Towards higher-dimensional structured light显示文摘Structured light refers to the arbitrarily tailoring of optical fields in all their degrees of freedom(DoFs),from spatial to temporal.Although orbital angular momentum(OAM)is perhaps the most topical example,and celebrating 30 years since its connection to the spatial structure of light,control over other DoFs is slowly gaining traction,promising access to higher-dimensional forms of structured light.Nevertheless,harnessing these new DoFs in quantum and classical states remains challenging,with the toolkit still in its infancy.In this perspective,we discuss methods,challenges,and opportunities for the creation,detection,and control of multiple DoFs for higher-dimensional structured light.We present a roadmap for future development trends,from fundamental research to applications,concentrating on the potential for larger-capacity,higher-security information processing and communication,and beyond. | Chao He Yijie Shen Andrew Forbes | 2022 | Light(Science & Applications)2022,11,8: | 1 |

| 20 | Prediction of Renal Function by Urinary Lead and Cadmium - Based on Classification Decision Tree and Logistic Regression Model显示文摘It is estimated that chronic kidney disease(CKD)will be the fifth leading cause of death in the world by 2040[1].Early recognition and intervention for kidney damage are essential.Estimated glomerular filtration rate(eGFR)can be calculated by measuring blood creatinine to evaluate glomerular function,and urinary N-acetyl-β-δ-glucosaminidase(UNAG)level is generally recognized as a marker of renal tubular injury.Exposure to lead(Pb)and cadmium(Cd)can damage renal function,leading to a decrease in eGFR and an increase in UNAG[2].Both Pb and Cd are easily accumulated in the body and then slowly released by the kidneys and excreted.So,urinary Pb(UPb)and Cd(UCd)levels can be used as biomarkers of exposure[3,4]. | LI Yang WANG Qing Yao TIAN Qing Hua AN Qi YANG Yu Tong ZHANG Jia Chen LI Shuang Jing ZHOU Han LIANG Yun Fen SHEN Wei Tong MU Li Na LEI Li Jian | 2024 | Biomedical and Environmental Sciences2024,37,3: | 0 |
