| 1 | COVID-19 Outbreak Caused by Contaminated Packaging of Imported Cold-Chain Products—Liaoning Province,China,July 2020显示文摘Summary What is known about this topic?Few major outbreaks of coronavirus disease 2019(COVID-19)have occurred in China after major nonpharmaceutical interventions and vaccines have been deployed and implemented.However,sporadic outbreaks that had high possibility to be linked to cold chain products were reported in several cities of China..What is added by this report?In July 2020,a COVID-19 outbreak occurred in Dalian,China.The investigations of this outbreak strongly suggested that the infection source was from COVID-19 virus-contaminated packaging of frozen seafood during inbound unloading personnel contact.What are the implications for public health practice?Virus contaminated paper surfaces could maintain infectivity for at least 17–24 days at-25℃.Exposure to COVID-19 virus-contaminated surfaces is a potential route for introducing the virus to a susceptible population.Countries with no domestic transmission of COVID-19 should consider introducing prevention strategies for both inbound travellers and imported goods.Several measures to prevent the introduction of the virus via cold-chain goods can be implemented. | Huilai Ma1 Jianqun Zhang Ji Wang Ying Qin Cao Chen Yang Song Liang Wang Jun Meng Lingling Mao Fengqin Li Ning Li Jian Cai Yong Zhang Dayan Wang Yunting Xia Hong Wang Shaofeng Jiang Xiang Zhao Peihua Niu Wenjie Tan Tao Ma Yecheng Yao Naiying Mao Zhen Zhu Tianjiao Ji Qian Yang Baoying Huang Li Zhao Jianxing Yu Li Bai Shuangli Zhu Dongyan Wang Yan Zhang Yingwei Sun Mingchun Luan Yanhai Wang Haibo Sun Shihong Yang Zhijian Bo Xiang Ren Zhongjie Li George Fu Gao Wei Yao Wenqing Yao Zijian Feng Wenbo Xu | 2021 | China CDC weekly2021，3，21： | 16 |
| 2 | The Pengguan tectonic dome of Longmen Mountains, Sichuan Province:Mesozoic denudation of a Neoproterozoic magmatic arc-basin system显示文摘Neoproterozoic igneous and metamorphic complexes occur as tectonic domes in the Longmen Mountains of the western margin of the Yangtze Block, and are important in reconstructing the Rodinian supercontinent and constraining the timing and mechanism of tectonic denudational processes. The Pengguan dome consists of granitic intrusions and metamorphic rocks of the Huangshuihe Group and is tectonically overlain by ductilly deformed Sinian to Paleozoic strata. The plutonic intrusions consist of granites with abundant amphibolite enclaves. New LA-ICP-MS zircon U-Pb dating yielded an emplacement age of 809±3 Ma and a protolith age of 844±6 Ma for the granite. The granitic rocks have geochemical signatures typical of A-type granites, indicating their formation under an extensional environment, by melting of newly formed tonalite-trondhjemite-granodiorite (TTG) rocks. A detachment fault, characterized by variable ductile shear deformation of S-C fabric and ESE-ward kinematics, separates the Pengguan dome from the Sinian-Paleozoic cover. 40Ar/39Ar dating of muscovite from the mylonite in the detachment fault of the dome demonstrates that ductile deformation occurred at ~160 Ma. This study indicates the existence of a Neoproterozoic magmatic arc-basin system, which was denudated by a Jurassic middle crustal ductile channel flow along the Longmenshan thrust belt. | YAN DanPing ZHOU MeiFu WEI GuoQing GAO JianFeng LIU ShaoFeng XU Ping SHI XiaoYing | 2008 | Science China Earth Sciences2008，51，11： | 9 |

No fuzi-cake-separated moxibustion was performed in the control group. After treatment, the score for symptoms of first urination, urinary time, urinary volume, 24 h remaining urinary volume, incidence of uroschesis, and rate of controlling dysuria were compared to evaluate the curative effect of preventing post-operative dysuria.RESULTS: The score for symptoms of first urination,24 h remaining urinary volume(maximum 120 m L vs 250 m L, and less than 10 m L in 24 cases vs 15 cases), and the rate of controlling dysuria(83.34% vs30%) were significantly better(P<0.05, P<0.05, and P<0.001, respectively) in the treatment compared with the control group. There was no statistical difference(P>0.05) between the two groups in first post-operative urinary time, urinary volume, or incidence of 24 h uroschesis.CONCLUSION: Fuzi-cake-separated moxibustion at Zhongji(CV 3) and Guanyuan(CV 4) can better prevent post-operative dysuria, effectively promote the functional restoration of the urinary bladder,and control the incidence of post-operative dysuria. | Yan Yue Lijun Tao Jianqiao Fang Qi Xie Shaofeng He Chunxia Huang Xueming Yang | 2014 | Journal of Traditional Chinese Medicine2014，34，5： | 4 |
| 5 | The toxic effect of solubilizing excipients on Tetrahymena thermophila BF_5 growth investigated by microcalorimetry显示文摘The toxic effect of different solubilizing excipients on the growth and metabolism of Tetrahymena thermophila BF5(T.t.BF5) at various concentrations was investigated by microcalorimetry.The thermogenic curves of T.t.BF5 growth were determined at 28°C,and were evaluated by dynamic parameters.The results indicated that the values of growth rate constant(k),maximum power(P1,P2),peak time(T1,T2) and total quantity of heat(Q) varied for different excipients.There was a good linear relationship between k and concentrations(r>0.95,P<0.01).5% inhibition concentration(IC5) of poloxamer 188,Tween 80,PEG 600,PEG 400 and Tween 20 was 2.18,1.07,1.35,0.58,and 0.045 mg/mL,respectively.After the principal component analysis(PCA),Q,k and P1 could characterize the effect of these excipients on T.t.BF5 growth.Comprehensive evaluation indicated that compared with the control group,poloxamer 188 had the weakest toxicity and Tween 20 had the strongest toxicity. | ZHANG ShaoFeng YAN Dan TANG HuiYing YANG Ming WANG YueSheng XIAO XiaoHe | 2010 | Chinese Science Bulletin2010，55，18： | 4 |
| 6 | Increased Expression of Intercellular Adhesion Molecule-1,Vascular Cellular Adhesion Molecule-1 and Leukocyte Common Antigen in Diabetic Rat Retina显示文摘Purpose: To understand the expression and distribution of intercellular adhesion molecule- 1(ICAM- 1),vascular cellular adhesion molecule- 1 (VCAM- 1)and CD45 (Leukocyte Common Antigen) in the control nondiabetic and various courses of diabetic rats retina. To explore the role of adhesion molecules (Ams) and the adhesion of leukocytes to vascular endothelial cells via Ams in diabetic retinopathy(DR).Methods: Sixty healthy adult male Wistar rats were randomly divided into diabetic groups(induced by Streptozotocin, STZ) and normal control groups. Rats in these two groups were further randomly divided into 3, 7, 14, 30, 90 and 180 days-group,including 5 rats respectively. The immunohistochemical studies of ICAM-1, VCAM-1 and CD45 were carried out in the retinal digest preparations or retinal paraffin sections, and the results were analyzed qualitatively, semi-quantitatively.Results: No positive reaction of VCAM-1 was found, and weak reactions of ICAM-1,CD45 were found in nondiabetic rats retina. The difference of 6 control groups had no statistical significance(P > 0.05). The increased ICAM-1 and CD45 staining pattern were detectable 3 days after diabetes induction, and a few VCAM-1 positive cells were observed in the retinal blood capillaries. The difference of diabetes and control is significant( P < 0.05).Following the course, the expressions of ICAM-1, VCAM-1 and CD45 were increasingly enhanced, reaching a peak at the 14th day.Conclusion: Increased expression of ICAM-1, VCAM-1 and leukocytes adhering and stacking in retinal capillaries are the very early events in DR. Coherence of expression and distribution of the three further accounts for it is the key point for the onset of DR that Ams mediates leukocytes adhesion and endothelial cell injury. | Ningyan Bai, Shibo Tang~#, Jing Ma, Yan Luo, Shaofeng Lin Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou 510060, China | 2003 | Eye Science2003，19，3： | 4 |

| 14 | Constraint strength and axial/radial particle velocity profiles for an integrated riser outlet显示文摘To study axial/radial profiles of particle velocity in the affected region of an integrated riser outlet,a cold model was developed for the integrated riser reactor combining the gas-solid distributor with the fluidized bed.Constraints,related to the gas-solid distributor and the upper fluidized bed,imposed on the particle flow in the riser outlet region,were investigated experimentally.The experimental results showed that with increasing superficial gas velocity,these constraints have strong influences on particle flow behavior,the particle circulation flux in the riser,and the height of the static bed material of the upper fluidized bed.When the constraints have greater prominence,the axial profile of the cross-sectionally averaged particle velocity in the outlet region initially increases and then decreases,the rate of decrease being proportional to the constraint strength.Along the radial direction of the outlet section,the region where the local particle velocity profile tends to decrease appears near the dimensionless radius r/R = 0.30 initially and then,with increasing constraint strength,gradually extends to the whole section from the inner wall.Based on the experimental data,an empirical model describing the constraint strength was established.The average relative error of the model is within 7.69%. | Dewu Wang Chaoyu Yan Chunxi Lu Rui Li Bin Zhao Shaofeng Zhang | 2015 | Particuology2015，13，4： | 1 |

| 16 | Polydopamine/polyethyleneimine co-crosslinked graphene oxide for the enhanced tribological performance of epoxy resin coatings显示文摘To enhance the wear resistance of graphene oxide(GO)nano-filled epoxy resin(EP)coatings with ex-cellent dispersion,GO were modified using a co-crosslinking strategy between polydopamine(PDA)and polyethyleneimine(PEI)through an environmentally friendly,simple and low-cost process.High-density amino-branched PEI and highly adhesive PDA formed covalent bond cross-links with GO(PDA/PEI-GO)through the Michael addition and Schiffbase reactions.With the introduction of amino active sites,the PDA self-polymerization reaction time was significantly shorted from 24 to 6 h.The covalently cross-linked network increased the lamellar spacing of GO and enhanced the interfacial bonds between the PDA/PEI-GO lamellae and EP matrix.Due to the improved dispersion and surface activity of GO,the PDA/PEI-GO nano-filled EP coating exhibited excellent wear resistance.Reciprocating friction with GCr15 stainless steel ball,the average friction coefficient and wear rate of the coating were reduced by 31.9%and 62.7%,respectively,compared to the pure EP coating.In addition,the wear mechanism of the PDA/PEI-GO/EP coating changed from adhesive and fatigue wear to abrasive wear,and it maintained good wear resistance by forming a GO lubrication transfer film on the counterpart surface.Therefore,this study may provide a new strategy for improving the dispersion of graphene in wear-resistant polymer materials for practical applications. | Shaofeng Zhou Jin Yan Jialin Chen Huimin Yan Yin Zhang Jin Huang Guizhe Zhao Qiaoxin Zhang Yaqing Liu | 2023 | Journal of Materials Science & Technology2023，，5： | 1 |
| 17 | The Research Progression of Calcitonin for the Therapy of Renal Osteodystrophy显示文摘Calcitonin is a common medicine used in the treatment of osteoporosis,which could restrain the activity of osteoclasts,stop the loss of osteocalcin and reduce the transfer of osteocalcin.Calcitonin can also be used in the treatment of the pain-caused diseases which usually cause by hypercalcemia and others such like Paget's disease and bone tumors.As is approved by several clinic researches,calcitonin is powerful in adjusting the level of calcium,phosphorus and PTH during the treatment of renal osteodystrophy.In addition,it could improves the life quality of the patients who suffered from chronic kidney disease(CKD)and extending their life period.At present,several studies have shown us Calcitonin could be treated in renal osteodystrophy.However,the treatment experiences of Calcitonin are still lacking.Better understanding of the clinical evaluation for calcitonin in the treatment of renal osteodystrophy will hopefully help us to improve outcomes for these patients. | Yingyan LI Sibo HUANG Shengling HUANG Shuang CUI Xiangnan DONG Yueling ZHU Baozhang GUAN Taksui WONG Bing YAN Bo HU Xin CHEN Shanshan LI Fanna LIU Huiyuan ZHENG Tong LIU Hongwei HU Shaofeng HUANG Shufei ZENG Chen YUN Wolfgang Pommer Zuhui CHEN Lianghong YIN Berthold Hocher | 2017 | 临床医学工程2017，24，S1： | 0 |
| 18 | The Pathogenesis of the Mechanism of FGF23 in Chronic Kidney Disease Patients with Vascular Calcification显示文摘Fibroblast growth factor 23(FGF23)is a protein synthesized by bone cell and the osteoblast with endocrine function.The main role of FGF23 is to regulate serum phosphorus and 1,25(OH)2 D3 levels,it also plays an important role in calcium and phosphorus metabolism.The role of FGF23 in renal disease is to inhibit of phosphorus reabsorption,promote urinary phosphorus excretion and maintain a stable blood phosphorus level.Patients with chronic kidney disease(CKD)have more risk to suffer cardiovascular disease(CVD)which is related to the abnormal metabolism of calcium and phosphorus.FGF23,as newly discovered cardiovascular risk marker,several studies have shown that FGF23 level associates with multiple cardiovascular risk factors in CKD patients,especially in CKD patients with vascular calcification.To explore its pathogenesis of vascular calcification in CKD patients is particularly important,and that may help to take appropriate measures to improve the prognosis of CKD patients. | Shanshan LI Wenyu GNOG Sibo HUANG Lianghong YIN Bo HU Xiangnan DONG Taksui WONG Fanna LIU Yingyan LI Yueling ZHU Xin CHEN Baozhang GUAN Shengling HUANG Shuang CUI Bing YAN Hongwei HU Shaofeng HUANG Yongpin LU Shufei ZENG Chen YUN Berthold Hocher Wolfgang Pomme | 2017 | 临床医学工程2017，24，S1： | 0 |
