1Consensus on the application of negative pressure wound therapy of diabetic foot wounds显示文摘Because China is becoming an aging society,the incidence of diabetes and diabetic foot have been increasing.Diabetic foot has become one of the main health-related killers due to its high disability and mortality rates.Negative pressure wound therapy(NPWT)is one of the most effective techniques for the treatment of diabetic foot wounds and great progress,both in terms of research and its clinical application,has been made in the last 20 years of its development.However,due to the complex pathogenesis and management of diabetic foot,irregular application of NPWT often leads to complications,such as infection,bleeding and necrosis,that seriously affect its treatment outcomes.In 2020,under the leadership of Burns,Trauma and Tissue Repair Committee of the Cross-Straits Medicine Exchange Association,the writing group for‘Consensus on the application of negative pressure wound therapy of diabetic foot wounds’was established with the participation of scholars from the specialized areas of burns,endocrinology,vascular surgery,orthopedics and wound repair.Drawing on evidence-based practice suggested by the latest clinical research,this consensus proposes the best clinical practice guidelines for the application and prognostic evaluation of NPWT for diabetic foot.The consensus aims to support the formation of standardized treatment schemes that clinicians can refer to when treating cases of diabetic foot.Shizhao Ji Xiaobin Liu Jie Huang Junmin Bao Zhaohong Chen Chunmao Han Daifeng Hao Jingsong Hong Dahai Hu Yufeng Jiang Shang Ju Hongye Li Zongyu Li Guangping Liang Yan Liu Gaoxing Luo Guozhong Lv Xingwu Ran Zhongmin Shi Juyu Tang Aiping Wang Guangyi Wang Jiangning Wang Xin Wang Bing Wen Jun Wu Hailin Xu Maojin Xu Xiaofei Ye Liangxi Yuan Yi Zhang Shichu Xiao Zhaofan Xia 2021Burns & Trauma2021,9,1:17

3Switchable dual-wavelength Q-switched fiber laser using multilayer black phosphorus as a saturable absorber显示文摘Black phosphorus(BP), with thickness-dependent direct energy bandgaps(0.3–2 eV), shows an enhanced nonlinear optical response at near-and mid-infrared wavelengths. In this paper, we present experimentally multilayer BP flakes coated on microfiber(BCM) as a saturable absorber with a modulation depth of 16% and a saturable intensity of 6.8 MW∕cm^2. After inserting BCM into an Er-doped fiber ring laser, a stable dual-wavelength Q-switched state with central wavelengths of 1542.4 nm and 1543.2 nm(with wavelength spacing as small as 0.8 nm) is obtained with the aid of two cascaded fiber Bragg gratings as a coarse wavelength selector.Moreover, single-wavelength Q-switched operation at 1542.4 nm or 1543.2 nm is also realized, which can be switched between the two wavelengths flexibly just by adjusting the intracavity birefringence. These results suggest that BP combined with the cascaded fiber gratings can provide a simple and feasible candidate for a multiwavelength fiber laser. Our fiber laser may have potential applications in terahertz generation, laser radar,and so on.JUNMIN LIU Yu CHEN YING LI HAN ZHANG SHUIQIN ZHENG SHIXIANG Xu 2018Photonics Research2018,6,3:8
4Discovery and development of natural heat shock protein 90 inhibitors in cancer treatment显示文摘Heat shock protein 90(Hsp90)is a highly conserved molecular chaperone that plays a vital role in the signal transduction of cancers.Hsp90 inhibitors are able to inhibit Hsp90 or the complex of Hsp90 and co-chaperones resulting in the degradation of Hsp90-dependent client proteins through the ubiqui tina tion-proteasome pathway,thereby leading to the growth inhibition of tumor cells.This review will briefy discuss the molecular structure and biological function of Hsp90,and focus on a summary of recent progress in the development and testing of natural Hsp90 inhibitors and their different means by which they interact with Hsp90.Yong Li Dongmei Zhang Jun Xu Junmin Shi Lei Jiang Nan Yao Wencai Ye 2012Acta Pharmaceutica Sinica B2012,2,3:7
5Elimination of a Retrotransposon for Quenching Genome Instability in Modern Rice显示文摘Transposable elements(TEs)constitute the most abundant portions of plant genomes and can dramatically shape host genomes during plant evolution.They also play important roles in crop domestication.However,whether TEs themselves are also selected during crop domestication has remained unknown.Here,we identify an active long terminal repeat(LTR)retrotransposon,HUO,as a potential target of selection during rice domestication and breeding.HUO is a low-copy-number LTR retrotransposon,and is active under natural growth conditions and transmitted through male gametogenesis,preferentially inserting into genomic regions capable of transcription.HUO exists in all wild rice accessions and about half of the archaeological rice grains(1200–7000 years ago)and landraces surveyed,but is absent in almost all modern varieties,indicating its gradual elimination during rice domestication and breeding.Further analyses showed that HUO is subjected to strict gene silencing through the RNA-directed DNA methylation pathway.Our results also suggest that multiple HUO copies may trigger genomic instability through altering genome-wide DNA methylation and small RNA biogenesis and changing global gene expression,resulting in decreased disease resistance and yield,coinciding with its elimination during rice breeding.Together,our study suggests that negative selection of an active retrotransposon might be important for genome stability during crop domestication and breeding.Yu Peng Yingying Zhang Yijie Gui Dong An Junzhong Liu Xun Xu Qun Li Junmin Wang Wen Wang Chunhai Shi Longjiang Fan Baorong Lu Yiwen Deng Sheng Teng Zuhua He 2019Molecular Plant2019,12,10:2
6Assessing the genetic diversity of the critically endangered Chinese sturgeon Acipenser sinensis using mitochondrial markers and genome-wide single-nucleotide polymorphisms from RAD-seq显示文摘As a living fossil, the endangered Chinese sturgeon(Acipenser sinensis) has been considered a national treasure in China. Here,the famous Gezhouba Dam and Three Gorges Dam on the Yangtze River were built in 1988 and 2006, for economic purposes.The natural population of Chinese sturgeon has declined since then, as these dams block its migratory route to the original spawning grounds in the middle reaches of the Yangtze River. In 2013 and 2014, there was an absence of spawning where it typically happened near the Gezhouba Dam. Nevertheless, from April to June in 2015, over 1,000 larvae with different body lengths(10–35 cm) were detected along the Shanghai Yangtze Estuary; but only little is currently known about the population genetic structure of the Chinese sturgeon. Herein, we inferred population genetic parameters from 462 available Chinese sturgeon specimens based on a 421-bp fragment of the mitochondrial DNA(mtDNA) D-loop region and 1,481,620 SNPs(singlenucleotide polymorphisms) generated by restriction site-associated DNA sequencing(RAD-seq). For the D-loop dataset, 15 haplotypes were determined. Randomly picked 23 individuals, representing the 15 D-loop haplotype groups, were subsequently used for further RAD-seq validation. The average nucleotide diversity calculated from the mtDNA and RAD datasets was 0.0086 and 0.000478, respectively. The overall effective female population size was calculated to be 1,255 to 2,607, and the long-term effective population size was estimated to range from 11,950 to 119,500. We observed that the genetic variability and the effective female population size of the current population in the Yangtze River are severely low, which are similar to the data reported over 10 years ago. The deduced relatively small effective population of female fish, limiting the genetic connectivity among Chinese sturgeon, should be considered a serious threat to this endangered species.Jian Liu Xinxin You Pao Xu Ping Zhuang Yueping Zheng Kai Zhang Min Wang Yunyun Lv Gangchun Xu Feng Zhao Jianhui Wu Houyong Fan Jianan Xu Zhiqiang Ruan Chao Bian Kai Liu Dongpo Xu Jinhui Chen Junmin Xu Qiong Shi 2018Science China(Life Sciences)2018,61,9:2
7Chromobox homolog 4 overexpression inhibits TNF-α-induced matrix catabolism and senescence by suppressing activation of NF-κB signaling pathway in nucleus pulposus cells显示文摘Intervertebral disc degeneration(IDD)is featured as enhanced catabolism of extracellular matrix(ECM)in the nucleus pulposus(NP),in which tumor necrosis factor-alpha(TNF-α)-related cell senescence is involved.Chromobox homolog protein 4(CBX4)exhibits anti-inflammatory effects and shows promising therapeutic potential.Thus,in the present study,we explore the role of CBX4 in IDD.Immunohistochemistry staining reveals that CBX4 expression is decreased in severe degenerative NP tissues compared to mild degenerative tissues,and real-time PCR and western blot analysis results show that CBX4 expression is downregulated under TNF-αstimulation in NP cells.siRNA and adenoviruses are used to knockdown or overexpress CBX4,respectively.The results demonstrate that CBX4 knockdown augments the catabolism of ECM in human NP cells,while CBX4 overexpression in rat NP cells restores the ECM degradation induced by TNF-α,as illustrated by immunofluorescence and western blot analysis.In addition,transcriptome sequencing results reveal the regulatory effect of CBX4 on the cell cycle,and further western blot analysis and senescence-associatedβ-galactosidase staining assay indicate that CBX4 overexpression alleviates cell senescence in the presence of TNF-α.Moreover,the phosphorylation of p65,which indicates the activation of NF-κB signaling,is measured by western blot analysis and immunofluorescence assay,and the results reveal that CBX4 overexpression reduces the TNF-α-induced increase in the p-p65/p65 ratio.In addition,the effect of CBX4 overexpression in NP cells is suppressed by NF-κB agonist.In summary,our results indicate that CBX4 overexpression can suppress TNF-α-induced matrix catabolism and cell senescence in the NP by inhibiting NF-κB activation.This study may provide new approaches for preventing and treating IDD.Yangyang Zhang Shuangxing Li Junmin Hong Jiansen Yan Zhengqi Huang Jiajun Wu Zhihuai Deng Tianyu Qin Kang Xu Wei Ye 2022Acta Biochimica et Biophysica Sinica2022,54,7:2
8Experimental research on oil fi lm thickness and its microwave scattering during emulsifi cation显示文摘Synthetic Aperture Radar(SAR) plays a major role in identifying oil spills on the sea surface.However,obtaining information of oil spill thickness(volume) is still a challenge.Emulsification is an important process affecting the thickness and normalized radar cross section(NRCS) of oil film.Experiments of crude oil emulsification with C-band fully-polarized scatterometer were conducted combining airborne hyperspectral imaging spectrometer and 3 D laser scanner observation data,to provide experimental parameters and method to support accurate remote sensing monitoring on marine oil spill.It is further proved that through quantitative homogeneous emulsified oil spill experiments,to a certain extent,the NRCS of oil film increased during the emulsification process of crude oil.The backscattering mechanism of crude oil emulsification was explored using a semi-empirical model(SEM);the change of oil film NRCS was modulated by its dielectric constant and surface roughness,in which the dielectric constant showed a dominant effect.The relationship between thickness and NRCS of oil film was studied under two experimental conditions.The differences of NRCS between oil film and adjacent seawater(Δσ~0) and the damping ratio(DR) were found to have a linear relationship with oil thickness,which were best in the vertical polarization mode(VV) at 45° incident angle during the quantitative crude oil homogeneous emulsification process.In the natural emulsification process of continuous oil spill in which oil film was mixed with both crude oil and emulsified oil,an empirical equation of oil film thickness is preliminarily established.The Δσ~0,DR,and the empirical equation of oil film thickness were applied to the marine continuous oil spill incident on a 19-3 oil platform with spaceborne SAR image and successfully explained the distribution of the relative thickness of the oil film.Jie GUO Chenqi XU Genwang LIU Xi ZHANG Junmin MENG Guangbo REN 2022Journal of Oceanology and Limnology2022,40,4:2

10Colon hydrotherapy plus Traditional Chinese Medicine to treat non-alcoholic fatty liver disease:a pilot study显示文摘OBJECTIVE: To demonstrate the potential to treat non-alcoholic fatty liver disease(NAFLD) with colon hydrotherapy(CHT) plus Traditional Chinese Medicine(TCM).METHODS: A total of 20 patients were enrolled into the study and received CHT with TCM for 2 weeks.Body mass index(BMI) and levels of serum triglycerides(TG) and total cholesterol(TC) were compared between pre-treatment and post-treatment.RESULTS: Two-week treatment with CHT plus TCM significantly lowered BMI and reduced blood lipids.BMI decreased from 29.5 ± 4.3 to 25.4 ± 1.0, while mean TG levels decreased by 0.70 mmol/L on average from baseline and mean TC levels decreased by0.37 mmol/L. Forty-five percent of patients exhibited TC decreasing by more than 10% from baseline and25%ofpatientsexhibited TCdecreasingbymore than 20%. Sixty percent of patients exhibited TG decreasing by more than 20% and 20% of patients exhibited TG decreasing by more than 40%. However,high-density and low-density lipoprotein cholester-ol levels did not change significantly after intervention. No serious adverse events were reported.CONCLUSION: Our findings suggest that CHT plus TCM to treat NAFLD is promising and it might be a new treatment strategy for management of NAFLD.Xiao Huanming Jiang Junmin Xie Yubao Shi Meijie Tian Guangjun Zhao Pengtao Zhang Chaozhen Chen Huijun Xu Chanyuan Chi Xiaoling 2017Journal of Traditional Chinese Medicine2017,37,3:1

17Genomic selection of orange-spotted grouper(Epinephelus coioides)based on multiplex PCR enrichment capture sequencing显示文摘Orange spotted grouper(Epinephelus coioides)is an important mariculture fish,and genomic breeding of this grouper species has been hindered due to lack of efficient genotyping tools.Here,we developed a single nucleotide polymorphism(SNP)genotyping technology based on multiplex PCR enrichment capture sequencing,which mainly aims at target area for high-throughput sequencing,and 741 SNPs were designed for genomic selection(GS)of growth and ammonia tolerance traits at the same time.The multiplex PCR enrichment capture sequencing assay showed that the genotyping efficiency was more than 99%in the orange-spotted grouper and the predictive accuracy of body weight and ammonia tolerance traits was 82%and 96%,respectively.More importantly,the average identity of the sequences with these SNPs aligned to the genomes of giant grouper(E.lanceolatus)and brown-marbled grouper(E.fuscoguttatus)were both over 96%.Test data showed that the SNP genotyping efficiency was more than 94%in both giant grouper and brown-marbled grouper.In summary,these results indicated that the development of SNP loci and genotyping approach based on the multiple PCR enrichment capture sequencing are suitable for GS of growth and ammonia tolerance traits in various grouper species,and it would provide technical support for practical grouper breeding.Xinxin Shan Xinhui Zhang Zhiqiang Ruan Jieming Chen Qiong Shi Junmin Xu Xinxin You 2023Aquaculture and Fisheries2023,8,6:0
