3Guidelines on multidisciplinary approaches for the prevention and management of diabetic foot disease(2020 edition)显示文摘In recent years,as living standards have continued to improve,the number of diabetes patients in China,along with the incidence of complications associated with the disease,has been increasing.Among these complications,diabetic foot disease is one of the main causes of disability and death in diabetic patients.Due to the differences in economy,culture,religion and level of medical care available across different regions,preventive and treatment methods and curative results for diabetic foot vary greatly.In multidisciplinary models built around diabetic foot,the timely assessment and diagnosis of wounds and appropriate methods of prevention and treatment with internal and external surgery are key to clinical practice for this pathology.In 2019,under the leadership of the Jiangsu Medical Association and Chinese Diabetes Society,the writing group for the Guidelines on multidisciplinary approaches for the prevention and management of diabetic foot disease(2020 edition)was established with the participation of scholars from the specialist areas of endocrinology,burn injury,vascular surgery,orthopedics,foot and ankle surgery and cardiology.Drawing lessons from diabetic foot guidelines from other countries,this guide analyses clinical practices for diabetic foot,queries the theoretical basis and grades and gives recommendations based on the characteristics of the pathology in China.This paper begins with assessments and diagnoses of diabetic foot,then describes treatments for diabetic foot in detail,and ends with protections for high-risk feet and the prevention of ulcers.This manuscript covers the disciplines of internal medicine,surgical,nursing and rehabilitation and describes a total of 50 recommendations that we hope will provide procedures and protocols for clinicians dealing with diabetic foot.Aiping Wang Guozhong Lv Xingbo Cheng Xianghua Ma Wei Wang Jianchao Gui JiHu Meng Lu Guoping Chu Jin’an Chen Hao Zhang Yiqiu Jiang Yuedong Chen Wengbo Yang Lin Jiang Houfa Geng Rendong Zheng Yihui Li Wei Feng Boey Johnson Wenjuan Wang Dalong Zhu Yin Hu 2020Burns & Trauma2020,8,1:34
4Effect of dry density on ^(125)I diffusion in GMZ bentonite显示文摘Gaomiaozi(GMZ) bentonite is regarded as the favorable candidate backfilling material for a potential repository in China.It is important to understand the diffusion behavior of 125 I in GMZ bentonite and compare the diffusion behavior in GMZ and other types of bentonite like MX-80,Avonlea,etc.Therefore,through-and out-diffusion experiments were conducted to obtain the effective diffusion coefficient(D e) and distribution coefficient(K d).A computer code named Fitting for diffusion coefficient(FDP) was used for the experimental data processing and theoretical modeling.At the dry density of GMZ bentonite from 1600-2000 kg/m 3,the D e values of 125 I were(2.4-20.4) × 10-12 m 2 /s and K d values were constants.At dry density above 1800 kg/m 3,the diffusion behaviors were almost the same,indicating that the anion exclusion was ineffective.Out-diffusion results showed that the species of 125 I may be changed during the diffusion processing.It was probably caused by some organic matters or reducing substances in GMZ bentonite.Since the main composition of bentonite is montmorillonite,similar diffusion parameters were obtained in GMZ and other types of bentonite.The relationship of D e and accessible porosity(acc) could be described by Archie's law with exponent n = 1.2-2.8 for 125 I diffusion in bentonite,whereas n = 2.0 in GMZ bentonite.Furthermore,bentonite with the dry density of 1800 kg/m 3 was proposed as the backfilling materials used in the construction of high level radioactivity waste repository.WU Tao LI JinYing DAI Wei XIAO GuoPing SHU FuJun YAO Jun SU YuLan SHI Lei 2012Science China Chemistry2012,55,9:11

7Impacts of climatic and marine environmental variations on the spatial distribution of Ommastrephes bartramii in the Northwest Pacific Ocean显示文摘Ommastrephes bartramii is an ecologically dependent species and has great commercial values among the AsiaPacific countries. This squid widely inhabits the North Pacific, one of the most dynamic marine environments in the world, subjecting to multi-scale climatic events such as the Pacific Decadal Oscillation(PDO). Commercial fishery data from the Chinese squid-jigging fleets during 1995–2011 are used to evaluate the influences of climatic and oceanic environmental variations on the spatial distribution of O. bartramii. Significant interannual and seasonal variability are observed in the longitudinal and latitudinal gravity centers(LONG and LATG) of fishing ground of O. bartramii. The LATG mainly occurred in the waters with the suitable ranges of environmental variables estimated by the generalized additive model. The apparent north-south spatial shift in the annual LATG appeares to be associated with the PDO phenomenon and is closely related to the sea surface temperature(SST)and sea surface height(SSH) on the fishing ground, whereas the mixed layer depth(MLD) might contribute limited impacts to the distribution pattern of O. bartramii. The warm PDO regimes tend to yield cold SST and low SSH, resulting in a southward shift of LATG, while the cold PDO phases provid warm SST and elevated SSH,resulting in a northward shift of LATG. A regression model is developed to help understand and predict the fishing ground distributions of O. bartramii and improve the fishery management.YU Wei CHEN Xinjun YI Qian GAO Guoping CHEN Yong 2016Acta Oceanologica Sinica2016,35,3:6
8The RppC-AvrRppC NLR-effector interaction mediates the resistance to southern corn rust in maize显示文摘Southern corn rust(SCR),caused by the fungal pathogen Puccinia polysora,is a major threat to maize pro-duction worldwide.Efficient breeding and deployment of resistant hybrids are key to achieving durable control of SCR.Here,we report the molecular cloning and characterization of RppC,which encodes an NLR-type immune receptor and is responsible for a major SCR resistance quantitative trait locus.Further-more,we identified the corresponding avirulence effector,AvrRppC,which is secreted by P.polysora and triggers RppC-mediated resistance.Allelic variation of AvrRppC directly determines the effectiveness of RppC-mediated resistance,indicating that monitoring of AvrRppC variants in the field can guide the rational deployment of RppC-containing hybrids in maize production.Currently,RppC is the most frequently deployed SCR resistance gene in China,and a better understanding of its mode of action is crit-ical for extending its durability.Ce Deng April Leonard James Cahill Meng Lv Yurong Li Shawn Thatcher Xueying Li Xiaodi Zhao Wenjie Du Zheng Li Huimin Li Victor Llaca Kevin Fengler Lisa Marshall Charlotte Harris Girma Tabor Zhimin Li Zhiqiang Tian Qinghua Yang Yanhui Chen Jihua Tang Xintao Wang Junjie Hao Jianbing Yan Zhibing Lai Xiaohong Fei Weibin Song Jinsheng Lai Xuecai Zhang Guoping Shu Yibo Wang Yuxiao Chang Weiling Zhu Wei Xiong Juan Sun Bailin Li Junqiang Ding 2022Molecular Plant2022,15,5:6
9H_(3)PMo_(12)O_(40)-catalyzed coupling of diarylmethanols with epoxides/diols/aldehydes toward polyaryl-substituted aldehydes显示文摘A versatile heteropoly acid(H_(3)PMo_(12)O_(40))-catalyzed coupling of diarylmethanols with epoxides was established for the synthesis of polyaryl-substituted aldehydes.Furthermore,the catalytic system was also suitable for the reaction of diarylmethanols and diols/aldehydes.The application of such an earthabundant,readily accessible,and nontoxic catalyst provides a green approach for the construction of polyaryl-substituted aldehydes.Guoping Yang Yufeng Liu Ke Li Wei Liu Bing Yu Changwen Hu 2020Chinese Chemical Letters2020,31,12:4

11A botanical medicine dragon’s blood exhibited clinical antithrombosis efficacy similar to low molecular weight heparin显示文摘Deep vein thrombosis(DVT)is a common complication following traumatic fracture with a 0.5%–1%annual incidence.Low molecular weight heparin(LMWH)is the most commonly used anticoagulation drug for DVT prevention,but treatment with LMWH is invasive.Our aim is to compare the antithrombotic effect of dragon’s blood,an oral botanical anticoagulant medicine approved by the Chinese FDA,with LMWH in patients undergoing hip fracture surgery and to explore the molecular mechanisms of anticoagulation treatment.Our study recruited patients and divided them into LMWH and dragon’s blood treatment group.Coagulation index tests,Doppler ultrasound and mRNA sequencing were performed before and after anticoagulation therapy.There was no significant difference in postoperative DVT incidence between the two groups(23.1%versus 15.4%,P=0.694).D-dimer(D-D)and fibrinogen degradation product(FDP)showed significant reductions in both groups after anticoagulation treatments.We identified SLC4A1,PROS1,PRKAR2B and seven other genes as being differentially expressed during anticoagulation therapy in both groups.Genes correlated with coagulation indexes were also identified.Dragon’s blood and LMWH showed similar effects on DVT and produced similar gene expression changes in patients undergoing hip fracture surgery,indicating that dragon’s blood is a more convenient antithrombosis medicine(oral)than LMWH(hypodermic injection).Jiangbin Liang Song Mei Xiangyu Qiao Wei Pan Yan Zhao Shaohui Shi Yaling Zhai Haizhao Wen Guoping Wu Chengyu Jiang 2021Science China(Life Sciences)2021,64,10:4
12Sirtl regulates testosterone biosynthesis in Leydig cells via modulating autophagy显示文摘Dear Editor,Steroid hormones are crucial signal molecules that regulate a large number of physiological and developmental pro-cesses.Testosterone is the key steroid hormone required for the development of male characteristics and also supports the physiology of the male reproductive system(Sinclair et al.,2015).Testosterone is primarily produced by the Leydig cells residing in the testicular interstitium.The cholesterol acts as a substrate for the biosynthesis of testosterone.Since steroidogenic cells are capable of stor-ing only very ltte hormone,rapid synthesis of hormone requires the mobilization of the precursor cholesterol,chiefly stored as intracellular lipid droplets(LDs)(Danielsen et al.,2016).Leydig cells are the major sites to produce testos-terone,there are extremely active autophagy in them,and a decline in steroidogenesis has also been associated with the decline of autophagic flow.Moreover,the disruption of autophagy leads to decreased intracellular LDs,and there-fore affects testosterone synthesis in the Leydig cells(Danielsen et al..2016;Gao et al,2018).Muhammad Babar Khawar Chao Liu Fengyi Gao Hui Gao Wenwen Liu Tingting Han Lina Wang Guoping Li Hui Jiang Wei Li 2021Protein & Cell2021,12,1:3

14Development of microwave-induced thermo-acoustic tomography prototype system显示文摘Due to its advantages in both contrast and resolution compared with conventional microwave or ultrasound imaging system, microwave-induced thermo-acoustic tomography (MITAT) has received more and more concerns in biologic tissue image field. In this paper, an integrated prototype of MITAT system is presented. Using this system, some basic experiments for biologic tissue objects with high water-content imbedded in fatty material have been done. In the MITAT experiments, the signals generated by two porcine muscle tissue strips with millimeter order scale in cross-section were collected. Images with both good contrast and resolution were obtained. In order to demonstrate the advantages of MITAT, some ultrasonic experiments were studied using a commercial ultrasonic linear array system. The comparisons of the results of both systems show the good performance of the MITAT prototype system for the detection of high water content targets, which is generally the same as the tumor in biologic tissue.CHEN GuoPing ZHAO ZhiQin GONG Wei NIE ZaiPing LIU QingHuo 2009Chinese Science Bulletin2009,54,23:3
15Stability of linear discrete switched systems with delays based on average dwell time method显示文摘This paper deals with the problem of exponential stability for a class of linear discrete switched systems with constant delays.The switched systems consist of stable and unstable subsystems.Based on the average dwell time method, some switching signals will be found to guarantee exponential stability of these systems.The explicit state decay estimation is also given in the form of the solutions of linear matrix inequalities(LMIs).An example relating to networked control systems(NCSs) illustrates the effectiveness of the proposed method.WANG Yong WANG Wei LIU GuoPing 2010Science China(Information Sciences)2010,53,6:2
16Hearing analysis in heterozygous and homozygous klotho gene deficient mice显示文摘Objective: To understand the crucial role of the klotho gene in hearing development in mouse models.Methods: PCR was used to identify CBA mice with different genotypes, i.e. WT, heterozygous(klotho +/-)or homozygous(klotho-/-). Mice phenotype and weight were recorded postnatal 25 days(P-25) and auditory brainstem responses(ABR) were used to determine auditory function at P-60.Results: klotho-/-mice tended to have smaller size, lighter weight and higher ABR thresholds at P-60,showing early onset age-related hearing loss(ARHL).Conclusion: Heterozygous and homozygous klotho deficient mice exhibit different degrees of hearing loss at young age, with homozygous mice(klotho-/-) showing more severe hearing loss. Our results indicate that persisted expression of klotho protein in the inner ear may potentially delay the onset of ARHL and play an important role in the protection of auditory function.Na Yuan Shiwei Qiu Qian Wang Wei Zhuang Guoping Li Tiantian Sun Shiming Yang Yuehua Qiao Xi Shi 2018Journal of Otology2018,13,4:2
