1Chinese Trauma Surgeon Association for management guidelines of vacuum sealing drainage application in abdominal surgeries-Update and systematic review显示文摘Vacuum sealing drainage (VSD) is frequently used in abdominal surgeries. However, relevant guidelines are rare. Chin ese Trauma Surge on Associati on orga nized a committee composed of 28 experts across China in July 2017, aiming to provide an evidence-based recommendation for the application of VSD in abdominal surgeries.Eleven questions regarding the use of VSD in abdominal surgeries were addressed:(1) which type of materials should be respectively chosen for the intraperitoneal cavity, retroperitoneal cavity and superficial incisions?(2) Can VSD be preventively used for a high-risk abdominal incision w让h primary suture?(3) Can VSD be used in severely contaminated/infected abdominal surgical sites?(4) Can VSD be used for temporary abdominal cavity closure under some special conditions such as severe abdominal trauma, infection, liver transplantation and intra-abdominal volume increment in abdominal compartment syndrome?(5) Can VSD be used in abdominal organ inflammation, injury, or postoperative drainage?(6) Can VSD be used in the treatment of intestinal fistula and pancreatic fistula?(7) Can VSD be used in the treatment of intra-abdominal and extra-peritoneal abscess?(8) Can VSD be used in the treatment of abdominal wall wounds, wound cavity, and defects?(9) Does VSD in crease the risk of bleeding?(10) Does VSD increase the risk of intestinal wail injury?(11) Does VSD increase the risk of peritoneal adhesion? Focusing on these questions, evidence-based recommendations were given accordingly. VSD was strongly recommended regarding the questions 2-4. Weak recommendations were made regarding questions 1 and 5-11. Proper use of VSD in abdominal surgeries can lower the risk of infection in abdominal incisions with primary suture, treat severely contaminated/infected surgical sites and facilitate temporary abdominal cavity closure.Yang Li Pei-Yuan Li Shi-Jing Sun Yuan-Zhang Yao Zhan-Fei Li Tao Liu Fan Yang Lian-Yang Zhang Xiang-Jun Bai Jing-Shan Huo Wu-Bing He Jun Ouyang Lei Peng Ping Hu Yan-An Zhu Ping Jin Qi-Feng Shao Yan-Feng Wang Rui-Wu Dai Pei-Yang Hu Hai-Ming Chen Ge-Fei Wang Yong-Gao Wang Hong-Xu Jin Chang-Ju Zhu Qi-Yong Zhang Biao Shao Xi-Guang Sang Chang-Lin Yin 2019Chinese Journal of Traumatology2019,22,1:26
2Changes in Cooking and Nutrition Qualities of Grains at Different Positions in a Rice Panicle under Different Nitrogen Levels显示文摘Cooking and nutrition qualities of grain are two of the most important aspects of rice quality. To understand the difference in cooking and nutrition qualities among the grains at different positions within a rice panicle, the distributions of gel consistency (GC), amylose content (AC) and crude protein content (CPC) of grains in a panicle in association with different nitrogen levels (0, 120 and 240 kg/ha) were investigated by using two rice varieties, Yangdao 6 (indica) and Wuyujing 3 (japonica). In general, the grains at the basal part of a panicle had lower GC and higher AC than those at the upper or middle part of a panicle. The 1st grain on the secondary branch with earlier flowering exhibited the highest GC, whereas the 2nd grain on the primary branch with later flowering showed the highest AC. For Yangdao 6, CPC in the grains on the primary branches was lower at the middle part of a panicle than at the upper or basal part of a panicle. For Wuyujing 3, there were no significant differences in CPCs in the grains among the upper, middle and basal parts of a panicle. GC in the grains was increased, whereas AC was reduced from zero nitrogen application (0N) to low amount of nitrogen application (LN), and the result was reversed from LN to medium amount of nitrogen application (MN). CPC was increased with the increase in the amount of nitrogen application.DONG Ming-hui SANG Da-zhi WANG Peng WANG Xue-ming YANG Jian-chang 2007Rice science2007,14,2:14
3The recognition of adakite-type gneisses in the North Dabie Mountain and its implication to ultrahigh pressure metamorphic geology显示文摘Adakite is an igneous rock generated by the partial melting of subducting ocean slab in an island arc setting. Meanwhile, residuals of the slab-melting are transformed to eclogite or garnet-amphibolite during a slab subduction process. This note reports the adakite-type grey gneisses discovered in the North Dabie Mountain. These adakitic rocks are characterized by high AI2O3(14.97%-17.56%), Sr (545-941 μg/g), Sr/Y (44.71-218.98), La/Yb (16.70-97.50), and low Y (3.32-12.19μg/g), Yb (0.31-1.34 μg/g), Sc (0.92-4.2μg/g), as well as positive Sr anomaly but absent or positive Eu anomaly. They are different from the low aluminum grey gneisses with low AI2O3 (13.73%-14.38%), Sr (262-409 μg/g), Sr/Y (6.46-15.97) and La/Yb (1.90-22.60), high Y(21.79-36.24 μg/g), Yb (2.00-5.59 μg/g) , Sc (8.30%-12.70%), and negative Sr, Eu anomaly in the North Dabie Mountain. The adakite-type grey gneisses in the North Dabie Mountain were most probably formed by the partial melting of subducting ocean slab before theWANG Qiang XU Jifeng WANG Jianxin ZHAO Zhenhua WANG Renjing QIU Jiaxiang XIONG Xiaolin SANG Longkang PENG Lianhong 2000Chinese Science Bulletin2000,45,21:12
4Genome-wide Dissection of Co-selected UV-B Responsive Pathways in the UV-B Adaptation of Qingke显示文摘Qingke (Tibetan hulless barley) has long been cultivated and exposed to long-term and strong UV-B radiation on the Tibetan Plateau, which renders it an ideal species for elucidating novel UV-B responsive mechanisms in plants. Here we report a comprehensive metabolite profiling and metabolite-based genome-wide association study (mGWAS) using 196 diverse qingke and barley accessions. Our results demonstrated both constitutive and induced accumulation, and common genetic regulation, of metabolites from different branches of the phenylpropanoid pathway that are involved in UV-B protection. A total of 90 significant mGWAS loci for these metabolites were identified in barley-qingke differentiation regions, and a number of high-level metabolite trait alleles were found to be significantly enriched in qingke, suggesting co-selection of various phenylpropanoids. Upon dissecting the entire phenylpropanoid pathway, we identified some key determinants controlling natural variation of phenylpropanoid content, including three novel proteins, a flavone C-pentosyltransferase, a tyramine hydroxycinnamoyl acyltransferase, and a MYB transcription factor. Our study, furthermore, demonstrated co-selection of both constitutive and induced phenylpropanoids for UV-B protection in qingke.Xingquan Zeng Hongjun Yuan Xuekui Dong Meng Peng Xinyu Jing Qijun Xu Tang Tang Yulin Wang Sang Zha Meng Gao Congzhi Li Chujin Shu Zexiu Wei Wangmu Qimei Yuzhen Basang Jiabu Dunzhu Zeqing Li Lijun Bai Jian Shi Zhigang Zheng Sibin Yu Alisdair R.Fernie Jie Luo Tashi Nyima 2020Molecular Plant2020,13,1:9
5High Frame Rate Contrast-enhanced Ultrasound Helps Differentiate Malignant and Benign Focal Liver Lesions显示文摘Background and Aims:This study aimed to evaluate the diagnostic performance of high frame rate contrast-en-hanced ultrasound(H-CEUS)of focal liver lesions(FLLs).Methods:From July 2017 to June 2019,conventional con-trast-enhanced ultrasound(C-CEUS)and H-CEUS were per-formed in 78 patients with 78 nodules.The characteristics of C-CEUS and H-CEUS in malignant and benign groups and the differences between different lesion sizes(1-3 cm,3-5 cm,or>5 cm)of C-CEUS and H-CEUS were examined.The diagnostic performance of C-CEUS and H-CEUS was ana-lyzed.The chi-square test or Fisher’s exact test was used to assess inter-group differences.The receiver operating characteristic curve was plotted to determine the diagnostic performance of C-CEUS and H-CEUS.Results:There were significant differences in the enhancement area,fill-in direc-tion and vascular architecture between C-CEUS and H-CEUS for both benign and malignant lesions(all p=0.000-0.008),but there were no significant differences in washout results(p=0.566 and p=0.684,respectively).For lesions 1-3 cm in size,the enhancement area,fill-in direction,and vascular architecture on C-CEUS and H-CEUS were significantly dif-ferent(all p=0.000),unlike for lesions 3-5 cm or>5 cm in size.For differentiation of malignant from benign FLLs in the 1-3 cm group,H-CEUS showed sensitivity,specific-ity,accuracy,and positive and negative predictive values of 92.86%,95.0%,96.3%,90.48%and 93.75%,respectively,which were higher than those for C-CEUS(75.0%,70.0%,77.78%,66.67%and 72.91%,respectively).Conclusions:H-CEUS provided more vascular information which could help differentiate malignant from benign FLLs,especially for lesions 1-3 cm in size.Xiang Fei Peng Han Bo Jiang Lianhua Zhu Wenshuo Tian Maodong Sang Xirui Zhang Yaqiong Zhu Yukun Luo 2022Journal of Clinical and Translational Hepatology2022,10,1:8
6时间如何流逝:当代分析时间哲学与先秦儒道时间哲学的比较显示文摘莫尔在1951年就提出比较哲学应该走出泛泛地比较同异点之格局,而从哲学沟通上着眼的看法。本文即是依照这个方针来从事中西比较时间哲学。比较的一方是先秦儒道的时间观,另一方是当代分析时间哲学。目的不仅是从当代分析哲学角度给先秦时间哲学一个新的解析,而且欲以中国的传统时间观,对当代分析时间哲学的理论困境提出新的路向。文章以简介比较哲学的方法论为引言,然后介绍当代分析时间哲学中对时间流逝的辩论。议题以时间流逝为主,因为传统上时间的定义就是流逝的特性。在分析哲学中,一方是A理论,承认时间流逝的真实性。另一方则是B理论,否认时间流逝的客观存在。两方的议点触及种种问题:时间是否依赖于观察者的时空地位,时间是否能独立于人类经验而客观存在,所谓的'当下'有没有绝对客观的标准,时间是否流逝,以及时间是否真实存在。双方争得不分上下,但是没有一个理论能提供完满的看法。儒道的时间观都肯定时间的流逝,但是没有陷入A理论的人类主观论。本文的结论是儒道时间观是时间流逝的实在论。刘纪璐 Peng Fasheng Sang Qiubo 2015孔学堂2015,2,4:4
7Overview of the Solar Polar Orbit Telescope Project for Space Weather Mission显示文摘The Solar Polar ORbit Telescope(SPORT) project for space weather mission has been under intensive scientific and engineering background studies since it was incorporated into the Chinese Space Science Strategic Pioneer Project in 2011.SPORT is designed to carry a suite of remote-sensing and in-situ instruments to observe Coronal Mass Ejections(CMEs),energetic particles,solar high-latitude magnetism,and the fast solar wind from a polar orbit around the Sun.The first extended view of the polar regions of the Sun and the ecliptic enabled by SPORT will provide a unique opportunity to study CME propagation through the inner heliosphere,and the solar high-latitude magnetism giving rise to eruptions and the fast solar wind.Coordinated observations between SPORT and other spaceborne/ground-based facilities within the International Living With a Star(ILWS) framework can significantly enhance scientific output.SPORT is now competing for official selection and implementation during China's 13 th Five-Year Plan period of 2016-2020.XIONG Ming LIU Ying LIU Hao LI Baoquan ZHENG Jianhua ZHANG Cheng XIA Lidong ZHANG Hongxin RAO Wei CHEN Changya SUN Weiying WU Xia DENG Yuanyong HE Han JIANG Bo WANG Yuming WANG Chuanbing SHEN Chenglong ZHANG Haiying ZHANG Shenyi YANG Xuan SANG Peng WU Ji 2016空间科学学报2016,36,3:3
8A large-scale fatal outbreak of Pasteurella multocida among wild rodents in southwestern China显示文摘Background:Pasteurella multocida is an important and old zoonotic pathogen worldwide which has an impressive host spectrum including numerous domestic and wild animals as well as birds,causing specific diseases or outbreak with great economic impact.It has never been reported that P.multocida can cause an epidemic in wild rodents.In June 5–17,2016,more than 1000 rodent deaths of an unknown cause quickly spread in the PuEr City,Yunnan province,southwestern China.Methods:The rodents in affected areas and outside of the epidemic areas were collected and screened for possible known pathogens including Yersinia pestis,rabies virus and hantavirus as well as other bacteria.The possible bacterial pathogens were isolated both by culture medium and by mouse inoculation in parallel.The isolates were identified by the Vitek GNI card and PCR assays for 16S rRNA genes.The pathogen strains were selected for whole genome sequencing analysis.Results:A total of 123 rodents were collected from 25 sample sites at affected area,among of which,all 119 dead rodents were negative for the pathogen under consideration except P.multocida,and all four live rodents were negative for P.multocida.In addition,480 rodents collected from other 23 counties outside of the epidemic area in Yunnan were negative for with P.multocida.A total of 14 strains of P.multocida(six directly isolated from the field rodents and eight from the experimental mice that were injected with the organ substrates from the dead rodents)belonged to serogroup A and serogroup F represented by 9 N and 20 N were identified in these epidemic areas.Whole genome sequencing revealed that the serogroup F strain shared 99%similarity to P.multocida Pm70 from chicken,but contained a 50 k bp insertion sequence.The serogroup A strain shared 95%similarity to P.multocida FDAARGOS_385 from a human patient,but contained four large structural differences.Histological abnormalities were identified in the livers,lungs,hearts and brains of the inoculated mice.Conclusions:The simultaneous occurrence of both serotypes of P.multocida may have caused this sudden onset of mortality across the local rodent population in Yunnan Province,China.Further attention should be paid to this old bacterium in the world.Chun-Hong Du Yong Huang Jia-Fu Jiang Zi-Hou Gao Na Jia Shan Yang Chao-Nian Chen Shun-Gao Ma Yu-Ying Liang Bao-Gui Jiang Wei-Hong Sang Peng Wang Yun Liang Yun-Zhi Zhang Ji-Hua Zhou Shui-Ping Chen Frans Jongejan Zhi-Zhong Song Yi-Gang Tong Wu-Chun Cao 2020Journal of Biosafety and Biosecurity2020,2,2:3

10High-efficiency green micro-LEDs with GaN tunnel junctions grown hybrid by PA-MBE and MOCVD显示文摘We fabricated p-i-n tunnel junction(TJ)contacts for hole injection on c-plane green micro-light-emitting diodes(micro-LEDs)by a hybrid growth approach using plasma-assisted molecular beam epitaxy(PA-MBE)and metal–organic chemical vapor deposition(MOCVD).The TJ was formed by an MBE-grown ultra-thin unintentionally doped In Ga N polarization layer and an n^(++)∕n^(+)-GaN layer on the activated p^(++)-Ga N layer prepared by MOCVD.This hybrid growth approach allowed for the realization of a steep doping interface and ultrathin depletion width for efficient inter-band tunneling.Compared to standard micro-LEDs,the TJ micro-LEDs showed a reduced device resistance,enhanced electroluminescence intensity,and a reduced efficiency droop.The size-independent J-V characteristics indicate that TJ could serve as an excellent current spreading layer.All these results demonstrated that hybrid TJ contacts contributed to the realization of high-performance micro-LEDs with long emission wavelengths.YAOZHENG WU BIN LIU FEIFAN XU YIMENG SANG TAO TAO ZILI XIE KE WANG XIANGQIAN XIU PENG CHEN DUNJUN CHEN HAI LU RONG ZHANG YOUDOU ZHENG 2021Photonics Research2021,9,9:2
11Antagonistic interaction between male-killing and cytoplasmic incompatibility induced by Cardinium and Wolbachia in the whitefly,Bemisia tabaci显示文摘Cardinium and Wolbachia are maternally inherited bacterial symbionts of arthropods that can manipulate host reproduction by increasing the fitness of infected females.Here,we report that Cardinium and Wolbachia coinfection induced male-killing and cytoplasmic incompatibility(CI)when they coexisted in a cryptic species of whitefly,Bemisia tabaci Asia II7.Cardinium and Wolbachia symbionts were either singly or simul-taneously localized in the bacteriocytes placed in the abdomen of B.tabaci nymphs and adults.Cardinium-Wolbachia coinfection induced male-killing and resulted in a higher female sex ratio in the intraspecific amphigenetic progeny of Asia II7 IcwH and IcwL lines;interestingly,male-illing induction was enhanced with increased Cardinium titer.Moreover,single infection of Wolbachia induced partial CI in the Asia II7 Iw line and resulted in reduced fecundity,higher embryonic mortality,and lower female sex ratio.The uninfected Asia II7 Iu line had significantly higher fecundity,lower embryonic and nymphal mortalities,and a lower level of CI than both the Wolbachia infected Asia II7 Iw line and the Cardinium--Wolbachia-coinfected Asia II7 IcwH line.Our findings indicate that Cardinium-Wolbachia coinfection induced male-killing,which may have had antag-onistic effects on Wolbachia-induced CI in the Asia II7 whiteflies.For the first time,our study revealed that B.tabaci Asia II7 reproduction is co-manipulated by Cardinium and Wolbachia endosymbionts.Ning Lv Jing Peng Xin-Yi Chen Chang-Fei Guo Wen Sang Xing-Min Wang Muhammad ZAhmed Yong-Yu Xu Bao-Li Qiu 2021Insect Science2021,28,2:2
12Mesenchymal stem cells loaded on 3D-printed gradient poly(e-caprolactone)/methacrylated alginate composite scaffolds for cartilage tissue engineering显示文摘Cartilage has limited self-repair ability due to its avascular,alymphatic and aneural features.The combination of three-dimensional(3D)printing and tissue engineering provides an up-and-coming approach to address this issue.Here,we designed and fabricated a tri-layered(superficial layer(SL),middle layer(ML)and deep layer(DL))stratified scaffold,inspired by the architecture of collagen fibers in native cartilage tissue.The scaffold was composed of 3D printed depth-dependent gradient poly(e-caprolactone)(PCL)impregnated with methacrylated alginate(ALMA),and its morphological analysis and mechanical properties were tested.To prove the feasibility of the composite scaffolds for cartilage regeneration,the viability,proliferation,collagen deposition and chondrogenic differentiation of embedded rat bone marrow mesenchymal stem cells(BMSCs)in the scaffolds were assessed by Live/dead assay,CCK-8,DNA content,cell morphology,immunofluorescence and real-time reverse transcription polymerase chain reaction.BMSCs-loaded gradient PCL/ALMA scaffolds showed excellent cell survival,cell proliferation,cell morphology,collagen II deposition and hopeful chondrogenic differentiation compared with three individual-layer scaffolds.Hence,our study demonstrates the potential use of the gradient PCL/ALMA construct for enhanced cartilage tissue engineering.Yanyan Cao Peng Cheng Shengbo Sang Chuan Xiang Yang An Xiaochun Wei Zhizhong Shen Yixia Zhang Pengcui Li 2021Regenerative Biomaterials2021,8,3:2

16Retracted Article:Application of 3D printing technology in orthopedic medical implant-Spinal surgery as an example显示文摘Additive manufacturing has been used in complex spinal surgical planning since the 1990s and is now increasingly utilized to produce surgical guides,templates,and more recently customized implants.Surgeons report beneficial impacts using additively manufactured biomodels as pre-operative planning aids as it generally provides a better representation of the patient’s anatomy than on-screen viewing of computed tomography(CT)or magnetic resonance imaging(MRI).Furthermore,it has proven to be very beneficial in surgical training and in explaining complex deformity and surgical plans to patients/parents.This paper reviews the historical perspective,current use,and future directions in using additive manufacturing in complex spinal surgery cases.This review reflects the authors’opinion of where the field is moving in light of the current literature.Despite the reported benefits of additive manufacturing for surgical planning in recent years,it remains a high niche market.This review raises the question as to why the use of this technology has not progressed more rapidly despite the reported advantages–decreased operating time,decreased radiation exposure to patients intraoperatively,improved overall surgical outcomes,pre-operative implant selection,as well as being an excellent communication aid for all medical and surgical team members.Increasingly,the greatest benefits of additive manufacturing technology in spinal surgery are customdesigned drill guides,templates for pedicle screw placement,and customized patient-specific implants.In view of these applications,additive manufacturing technology could potentially revolutionize health care in the near future.Rong Feng Zhang Peng Yun Wang Ming Yang Xuebo Dong Xue Liu Yiguang Sang An Tong 2019International Journal of Bioprinting2019,5,2:1
