1A rapid advice guideline for the diagnosis and treatment of 2019 novel coronavirus(2019-nCoV) infected pneumonia(standard version)显示文摘In December 2019, a new type viral pneumonia cases occurred in Wuhan, Hubei Province;and then named '2019 novel coronavirus(2019-nCoV)' by the World Health Organization(WHO) on 12 January 2020. For it is a never been experienced respiratory disease before and with infection ability widely and quickly, it attracted the world’s attention but without treatment and control manual. For the request from frontline clinicians and public health professionals of 2019-nCoV infected pneumonia management, an evidence-based guideline urgently needs to be developed. Therefore, we drafted this guideline according to the rapid advice guidelines methodology and general rules of WHO guideline development;we also added the first-hand management data of Zhongnan Hospital of Wuhan University. This guideline includes the guideline methodology, epidemiological characteristics, disease screening and population prevention, diagnosis, treatment and control(including traditional Chinese Medicine), nosocomial infection prevention and control, and disease nursing of the 2019-nCoV. Moreover, we also provide a whole process of a successful treatment case of the severe 2019-nCoV infected pneumonia and experience and lessons of hospital rescue for 2019-nCoV infections. This rapid advice guideline is suitable for the first frontline doctors and nurses, managers of hospitals and healthcare sections, community residents, public health persons, relevant researchers, and all person who are interested in the 2019-nCoV.Ying-Hui Jin Lin Cai Zhen-Shun Cheng Hong Cheng Tong Deng Yi-Pin Fan Cheng Fang Di Huang Lu-Qi Huang Qiao Huang Yong Han Bo Hu Fen Hu Bing-Hui Li Yi-Rong Li Ke Liang Li-Kai Lin Li-Sha Luo Jing Ma Lin-Lu Ma Zhi-Yong Peng Yun-Bao Pan Zhen-Yu Pan Xue-Qun Ren Hui-Min Sun Ying Wang Yun-Yun Wang Hong Weng Chao-Jie Wei Dong-Fang Wu Jian Xia Yong Xiong Hai-Bo Xu Xiao-Mei Yao Yu-Feng Yuan Tai-Sheng Ye Xiao-Chun Zhang Ying-Wen Zhang Yin-Gao Zhang Hua-Min Zhang Yan Zhao Ming-Juan Zhao Hao Zi Xian-Tao Zeng Yong-Yan Wang Xing-Huan Wang 2020Military Medical Research2020,7,1:161
22018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up.Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu 2018Science Bulletin2018,63,23:54

5Propofol protects against blood-spinal cord barrier disruption induced by ischemia/reperfusion injury显示文摘Propofol has been shown to exert neuroprotective effects on the injured spinal cord.However,the effect of propofol on the blood-spinal cord barrier(BSCB) after ischemia/reperfusion injury(IRI) is poorly understood.Therefore,we investigated whether propofol could maintain the integrity of the BSCB.Spinal cord IRI(SCIRI) was induced in rabbits by infrarenal aortic occlusion for 30 minutes.Propofol,30 mg/kg,was intravenously infused 10 minutes before aortic clamping as well as at the onset of reperfusion.Then,48 hours later,we performed histological and m RNA/protein analyses of the spinal cord.Propofol decreased histological damage to the spinal cord,attenuated the reduction in BSCB permeability,downregulated the m RNA and protein expression levels of matrix metalloprotease-9(MMP-9) and nuclear factor-κB(NF-κB),and upregulated the protein expression levels of occludin and claudin-5.Our findings suggest that propofol helps maintain BSCB integrity after SCIRI by reducing MMP-9 expression,by inhibiting the NF-κB signaling pathway,and by maintaining expression of tight junction proteins.Li-jie Xie Jin-xiu Huang Jian Yang Fen Yuan Shuang-shuang Zhang Qi-jing Yu Ji Hu 2017Neural Regeneration Research2017,12,1:14
6Global significance of the carbon cycle in the karst dynamic system:evidence from geological and ecological processes显示文摘On the basis of proposing the existence of a karst carbon cycle and carbon sink at a watershed scale,this paper provides four pieces of evidence for;the integration of geology and ecology during the carbon cycle processes m the karst dynamic system,and estxmated the karst carbon sink effect using the methods of comparative monitoring of paired watersheds and the carbon stable isotope tracer technique.The results of the soil carbon cycle in Maocun,Guilin,showed that the soil carbon cycle in the karst area,the weathering and dissolution of carbonate rocks under the soil,resulted in a lower soil respiration of 25% in the karstoarea than in a non-karst area (sandstone and shale),and the carbon isotope results indicated that 13.46% of the heavy carbon of the hmestone is involved in the soil carbon cycle.The comparative monitoring results m paxred watersheds,suggesting that the HCO3 concentration m a karst spring is 10 times that of a rivulet in a non-karst area,while the concentration of inorganic carbon flux is 23.8 times.With both chemical stoichiometry and carbon stable isotopes,the proportion of carbon in karst springs derived from carbonate rocks was found to be 58.52% and 37.65% respectively.The comparison on carbon exchange and isotopes at the water-gas interface between the granite and carbonate rock basins in the Li River showed that the CO2 emission of the karst water is 10.92 times that of the allogenic water from the non-karst area,while the carbon isotope of HCO3^- in karst water is lighter by 8.62%.However,this does not mean that the karst water body has a larger carbon source effect.On the contrary,it means the karst water body has a greater karst carbon sink effect.When the karst subterranean stream in Zhaidi,Guilin,is exposed at the surface,carbon-rich karst water stimulated the growth of aquatic plants.The values of carbon stable isotopes in the same species of submerged plants gradually becomes heavier and heavier,and the 512 m flow process has a maximum range of 15.46%.The calculation results showed that 12.52% of inorganic carbon is converted into organic carbon.According to the data that has been published,the global karst carbon sink flux was estimated to be 0.53-0.58 PgC/a,equivalent to 31.18%-34.41% of the global forest carbon sink flux.In the meanwhile,the karst carbon sink flux in China was calculated to be 0.051 PgC/a,accounting for 68% of its forest carbon sink flux.Jian-hua Cao Xia Wu Fen Huang Bill Hu Chris Groves Hui Yang Chun-lai Zhang 2018China Geology2018,1,1:9
7Nutritional compositions of various potato noodles:Comparative analysis显示文摘In this study,three kinds of noodles,wheat,Shepody potato and Atlantic potato noodles,were produced with blended powder consisting of wheat flour and certain amounts of various potato flours.In order to investigate the effects of potato flour on the nutritional characteristics of noodles,the nutrient compositions of four types of noodles were analyzed:fresh noodle,dried noodle,fresh noodle after boiling,and dried noodle after boiling.Results showed that the contents of protein,crude fiber,total ash,reducing sugar,vitamin B1,vitamin B2,vitamin B3,vitamin C,most mineral elements,dietary fiber,and amino acids in potato noodles were higher than those in wheat noodles.Furthermore,drying and boiling could decrease the contents of vitamin B1,vitamin B3,and mineral elements in noodles,but the nutrient contents in potato noodles remained higher than those in wheat noodles.The comprehensive nutritional values of noodles were evaluated using the index of nutritional quality,the results showed that the nutritional value of Shepody potato noodles was the highest,followed by that of Atlantic potato noodles and then wheat noodles.Xu Fen Hu Honghai Dai Xiaofeng Liu Qiannan Huang Yanjie Zhang Hong 2017International Journal of Agricultural and Biological Engineering2017,10,1:9

9Cystathionine-γ-lyase ameliorates the histone demethylase JMJD3-mediated autoimmune response in rheumatoid arthritis显示文摘Cystathionine-γ-lyase(CSE),an enzyme associated with hydrogen sulfide(H2S)production,is an important endogenous regulator of inflammation.Jumonji domain-containing protein 3(JMJD3)is implicated in the immune response and inflammation.Here,we investigated the potential contribution of JMJD3 to endogenous CSE-mediated inflammation in rheumatoid arthritis(RA).Upregulated CSE and JMJD3 were identified in synovial fibroblasts(SFs)from RA patients as well as in the joints of arthritic mice.Knocking down CSE augmented inflammation in IL-1β-induced SFs by increasing JMJD3 expression.In addition,CSE−/−mice with collagen-induced arthritis(CIA)developed severe joint inflammation and bone erosion.Conversely,overexpressing CSE inhibited JMJD3 expression by the transcription factor Sp-1 and was accompanied by reduced inflammation in IL-1β-treated SFs.Furthermore,JMJD3 silencing or the administration of the JMJD3 inhibitor GSK-J4 significantly decreased the inflammatory response in IL-1β-treated SFs,mainly by controlling the methylation status of H3K27me3 at the promoter of its target genes.GSK-J4 markedly attenuated the severity of arthritis in CIA mice.In conclusion,suppressing JMJD3 expression by the transcription factor Sp-1 is likely responsible for the ability of CSE to negatively modulate the inflammatory response and reduce the progression of RA.Weijun Wu Ming Qin Wanwan Jia Zheng Huang Zhongzheng Li Di Yang Mengwei Huang Chenxi Xiao Fen Long Jianchun Mao Philip K.Moore Xinhua Liu Yi Zhun Zhu 2019Cellular & Molecular Immunology2019,16,8:9
10Decreased Average Albumin-to-Globulin Ratio During Radiotherapy Worsens the Prognosis of Esophageal Squamous Cell Carcinoma:Implications for Nutritional Management显示文摘Objective Malnutrition and cachexia are common in esophageal squamous cell carcinoma(ESCC)patients undergoing radiotherapy.This study evaluated how malnutrition-and cachexia-related indicators,including the albumin-to-globulin ratio(AGR),and their changes during radiotherapy predict the treatment outcomes.Methods We reviewed a total of 172 ESCC patients receiving radiotherapy(as a primary cohort)and performed a Cox regression analysis on potential prognostic factors,including the AGR,as well as the TNM stage and concomitant chemotherapy.A subsequent receiver operating characteristics(ROC)curve and Kaplan Meier survival analysis was performed for ESCC patients stratified by the average AGR cut-off point.Results In addition to the well-documented factors(i.e.TNM stage and concomitant chemotherapy),the average AGR was a significant prognostic factor for ESCC patients receiving radiotherapy.By plotting the ROC curve of the average AGR with regard to the ESCC prognosis,we obtained cut-off points for the overall patients(cut-off point:1.5,AUC:0.636),for patients with stageⅡ/Ⅲdisease(cut-off point:1.5,AUC:0.611),and for patients with stageⅣdisease(cut-off point:1.84,AUC:0.900).The ESCC patients with higher average AGR had a significantly more favorable OS compared with those with a lower average AGR.Notably,ESCC patients who had an increasingΔAGR during radiotherapy had a considerably more favorable OS compared with those with a decreasingΔAGR.All of these findings were reproducible in the validation cohort.Conclusion A lower average AGR is indicative of a poorer prognosis for ESCC patients following radiotherapy.Improving the nutritional status and preventing or ameliorating cachexia might contribute to improving the prognosis of ESCC patients.Fen Cai Xiu Lian Zhang Xiao Ling Wu Ting Ting Zhuang Lei Huang Yi Fei Tu Yuan Yuan Lu Min Xia Jiang Qing Ying Zhang Yan Lin Chang Chun Ma 2021Journal of Nutritional Oncology2021,6,2:8
11(x-Helical domain is essential for antimicrobial activity of high mobility group nucleosomal binding domain 2 (HMGN2)显示文摘Aim:To examine the antimicrobial spectrum and functional structure of highmobility group nucleosomal binding domain 2(HMGN2).Methods:OMIGA pro-tein structure software was used to analyze the two-dimensional structure ofHMGN2.Synthetic short peptides were generated for studying the relationshipbetween function and structure.Prokaryotic expression vectors were constructedfor the holo-HMGN2 and its helical domain.Their E coil-based products werealso prepared for antimicrobial testing.The antimicrobial assay included minimaleffective concentration,minimal inhibitory concentration,and minimal bacteri-cidal concentration.Results:OMIGA protein structure software analysis revealeda transmembrane or-helical structure(the putative antimicrobial domain)locatedfrom position 18 to 48 of the HMGN2 protein sequence.The antimicrobial assayshowed that the MIC of the recombinant holo-HMGN2 against E coli ML-35p(anampicillin-resistance strain),Pseudomonas aeruginosa ATCC 27853 and Candidaalbicans ATCC 10231 were 12.5,25,and 100 rag/L,respectively.Against the samemicroorganisms,the MIC of the synthetic HMGN2 α-helical domain were 12.5,25,and 100 mg/L,respectively,that is,the same as with the recombinant form ofHMGN2.In contrast,recombinant holo-HMGN2 was inactive against Staphylo-coccus aureus ATCC 25923.The synthetic N-terminal and C-terminal fragments ofHMGN2 had no antimicrobial activity against E coli ML-35p,P aeruginosa ATCC27853 or C albicans ATCC 10231.Conclusion:HMGN2 showed potent antimi-crobial activity against E coli ML-35p,P aeruginosa ATCC 27853 and,to someextent,against C albicans ATCC 10231,but was inactive against S aureus ATCC25923 in these assay systems.Its α-helical structure may be essential for theantimicrobial activity of HMGN2.Yun FEN Ning HUANG Qi WU Lang BAO Bo-yao WANG 2005Acta Pharmacologica Sinica2005,26,9:8
12Application of bone transgenic zebrafish in anti-osteoporosis chemical screening显示文摘Background: The zebrafish(Danio rerio) has recently been shown to be an ideal model to study bone disease including osteoporosis. The zebrafish osteoporosis model could be induced by glucocorticoid treatment with chemical staining for reflecting the level of bone mineralization. However, this methodology was unstable.Here, we developed a novel methodology to directly evaluate the bone mass and density.Methods: We generated and used the bone of transgenic zebrafish Tg(ola.sp7:nlsGFP) to evaluate the bone mass and density by measuring the areal extent and the integrated optical density(IOD) of enhanced green fluorescent protein(eGFP).This methodology was further compared with the traditional chemically stained method showing the bone mineralization. Furthermore, genes related to zebrafish osteoporosis were analyzed by quantitative reverse transcription-polymerase chain reaction(qRT-PCR).Results: Our results of new methods were consistent with those from chemically stained fish, following glucocorticoid-induction or epimedium flavonoid(FE)-rescue treatments. q RT-PCR analyses on mRNA levels revealed that glucocorticoid induces osteoporosis by downregulating the expression of osteoblast-related factors osterix,osteocalcin, and osteopontin, and upregulating the expression of osteoclast-related factor tartrate-resistant acid phosphatase. In FE-rescued fish, the expression of osteogenic factors osterix, osteocalcin, and osteopontin were increased.Conclusion: Compared to the traditional chemical staining methods, the new osteoporosis model using Tg(ola.sp7:nlsGFP) is more convenient and efficient for studying osteoporosis in vivo, and especially for high-throughput anti-osteoporosis drug screening.Hong-xin Huang Hao Lin Fen Lan Yong-fu Wu Zhen-guo Yang Jing-jing Zhang 2018Animal Models and Experimental Medicine2018,1,1:8
13Immunopotentiator Thymosin Alpha-1 Promotes Neurogenesis and Cognition in the Developing Mouse via a Systemic Th1 Bias显示文摘In early life, the immune system plays an essential role in brain development. In our study, the immunopotentiator thymosin alpha-1(Ta1) was peripherally administered to neonatal mice to explore whether the peripheral immunopotentiator affects neurodevelopment and cognition, and to further investigate the relevant mechanism. Compared with the control group, the Ta1 mice displayed better cognitive abilities in early life. The numbers of 5-bromodeoxyuridine(Brd U)+, nestin+,T-box transcription factor 2(Tbr2)+, Brd U+/doublecortin(DCX)+, Brd U+/ionized calcium-binding adaptor molecule 1(Iba1)+, and Brd U+/neuronal nuclei(Neu N)+ cells in the hippocampus were increased in the Ta1 group,accompanied by increased interleukin-4(IL-4), interferon-gamma, brain-derived neurotrophic factor, nerve growth factor, and insulin-like growth factor-1 as well as decreased IL-6 and tumor necrosis factor-a. Furthermore, the Ta1-group showed a Th1-polarized immune response, and the neurotrophic factors were positively associated with the Th1/Th2 ratio. More importantly, administration of Ta1 blocked lipopolysaccharide-induced impairment of hippocampal neurogenesis in early life. These findings suggest that peripheral Ta1 contributes to neurogenesis and cognition probably through a systemic Th1 bias, as well as neuroprotection against LPS infection by Ta1.Ge Wang Fen He Yunlong Xu Yuwei Zhang Xiao Wang Chunhua Zhou Yihong Huang Juntao Zou 2017Neuroscience Bulletin2017,33,6:8
14Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 2020Biomedical and Environmental Sciences2020,33,12:8
15Molecular Characterization and Correlation with β-lactam Resistance of Streptococcus pneumonia Isolates in Hangzhou,China显示文摘Penicillin-binding proteins(PBPs) are the target of β-lactam antibiotics(the major treatment for Streptococcus pneumoniae infections),and mutations in PBPs are considered as a primary mechanism for the development of β-lactam resistance in S.pneumoniae.This study was conducted to investigate the mutations in the PBPs of clinical S.pneumoniae isolates in Hangzhou,China,in correlation with β-lactam resistance.Results showed that 19 F was the predominant serotype(7/27) and 14 of the S.pneumoniae isolates were resistant to both penicillin G and cephalosporin.Genotyping results suggested that β-lactam-resistant isolates primarily exhibited single-site mutations in both the STMK and SRNVP motifs of pbp1 a in combination with double-site mutations in the STMK motif of pbp2 x,which might be the primary mechanisms underlying the β-lactam resistance of the isolates in this study.chu mei fen liu xiao xiang zhang shao ni huang yan ying du peng wang li fang ji lei yan jie sun ai hua 2018Biomedical and Environmental Sciences2018,31,5:7
16Color-related chlorophyll and carotenoid concentrations of Chinese kale can be altered through CRISPR/Cas9 targeted editing of the carotenoid isomerase gene BoaCRTISO显示文摘The carotenoid isomerase gene(BoaCRTISO)of Chinese kale was targeted and edited using the CRISPR/Cas9 system in the present study.The results showed a high mutation rate(81.25%),and 13 crtiso mutants were obtained.Only two types of mutations,insertions and replacements,were found.Both the total and individual carotenoid and chlorophyll concentrations of the biallelic and homozygous mutants were reduced,and the total levels declined by 11.89–36.33%.The color of the biallelic and homozygous mutants changed from green to yellow,likely reflecting a reduction in the color-masking effect of chlorophyll on carotenoids.The expression levels of most carotenoid and chlorophyll biosynthesis-related genes,including CRTISO,were notably lower in the mutants than in the WT plants.In addition,the functional differences between members of this gene family were discussed.In summary,these findings indicate that CRISPR/Cas9 is a promising technique for the quality improvement of Chinese kale and other Brassica vegetables.Bo Sun Min Jiang Hao Zheng Yue Jian Wen-Li Huang Qiao Yuan Ai-Hong Zheng Qing Chen Yun-Ting Zhang Yuan-Xiu Lin YanWang Xiao-Rong Wang Qiao-Mei Wang Fen Zhang Hao-Ru Tang 2020Horticulture Research2020,7,1:7
17Neuroimaging mechanisms of high-frequency repetitive transcranial magnetic stimulation for treatment of amnestic mild cognitive impairment:a double-blind randomized sham-controlled trial显示文摘Individuals with amnestic mild cognitive impairment(aMCI)have a high risk of developing Alzheimer’s disease.Although repetitive transcranial magnetic stimulation(rTMS)is considered a potentially effective treatment for cognitive impairment in patients with aMCI,the neuroimaging mechanisms are poorly understood.Therefore,we performed a double-blind randomized sham-controlled trial in which rTMS was applied to the left dorsolateral prefrontal cortex of aMCI patients recruited from a community near the Third Hospital Affiliated to Sun Yat-sen University,China.Twenty-four patients with aMCI were randomly assigned to receive true rTMS(treatment group,n=12,6 men and 6 women;age 65.08±4.89 years)or sham stimulation(sham group,n=12,5 men and 7 women;age 64.67±4.77 years).rTMS parameters included a stimulation frequency of 10 Hz,stimulation duration of 2 seconds,stimulation interval of 8 seconds,20 repetitions at 80%of the motor threshold,and 400 pulses per session.rTMS/sham stimulation was performed five times per week over a period of 4 consecutive weeks.Our results showed that compared with baseline,Montreal Cognitive Assessment scores were significantly increased and the value of the amplitude of low-frequency fluctuation(ALFF)was significantly increased at the end of treatment and 1 month after treatment.Compared with the sham group,the ALFF values in the right inferior frontal gyrus,triangular part of the inferior frontal gyrus,right precuneus,left angular gyrus,and right supramarginal gyrus were significantly increased,and the ALFF values in the right superior frontal gyrus were significantly decreased in the treatment group.These findings suggest that high-frequency rTMS can effectively improve cognitive function in aMCI patients and alter spontaneous brain activity in cognitive-related brain areas.This study was approved by the Ethics Committee of Shenzhen Baoan Hospital of Southern Medical University,China(approval No.BYL20190901)on September 3,2019 and registered in the Chinese Clinical Trials Registry(registration No.ChiCTR1900028180)on December 14,2019.Li-Qiong Yuan Qing Zeng Dan Wang Xiu-Yun Wen Yu Shi Fen Zhu Shang-Jie Chen Guo-Zhi Huang 2021Neural Regeneration Research2021,16,4:6
18Radical microsurgical treatment of intramedullary spinal cord tumors显示文摘背景针的绳索肿瘤在完全的移动和最小的手术后的赤字瞄准的 intramedullary 的外科的治疗。这研究被承担评估 intramedullary 的 themicrosurgical 特征为外科和预后的针的绳索肿瘤和时间。方法有 intramedullary 的 21 个病人针的绳索肿瘤在 NanfangHospital 被对待,广州,中国后来, 2000 回顾地被学习。十五个病人是人和 6women, 2—60 年(平均数 29.28 年) 。13 个病人在颈的片断有肿瘤, 4 在髓质颈的片断, 1 在 cervicothoracic 分割,并且 3 在里面胸的脊骨。Allthe 病人由 laminectomy 通过以后的途径为肿瘤经历了微外科。Thetumor 通过背面的 myelotomy 被暴露,然后,肿瘤飞机从 entirerostrocaudal 区域小心地被移开。dura 习惯性地是 sutured。在占据太多针的片断的肿瘤的情况下,钛长带被使用重建脊椎的板并且保留脊梁骨桌子。所有病人在手术以后早受到先生成像。肿瘤的结果 Completeremoval 在 1 在 15 个病人,在 5 的小计移动,和部分切除术被做。神经病学的恢复首先与病人的外科手术前的神经病学的条件有关。有次要的神经病学的赤字的病人证明在早手术后的时期的感觉的马厩和马达功能或次要的损失,和神经病学的功能趋于与时间改善。但是那些几乎不能与重要或长期的赤字表明任何恢复。在肿瘤和正常绳索织物之间的解剖接口是影响外科的移动的程度的最重要的因素。结论 Intramedullary 针的绳索肿瘤主要发生在颈的片断,与是的 glioma 最普通的类型。Microsurgery 是选择,由肿瘤,飞机能完全是 resected 的主要治疗。当保留神经病学的功能时,优秀微外科的专家知识和肿瘤飞机的小心的识别对肿瘤的移动必要。钛长带固定是有用的重建脊椎的稳定性。病人的 Preoperativeneurological 条件是直接与他们的手术后的恢复有关。Weunderscore 早诊断的重要性和 intramedullaryspinal 绳索肿瘤的激进的微外科的治疗。PENG Lin QI Song-tao CHEN Zhuang FEN Wen-feng FANG Lu-xiong HUANG Li-jing CHENG Jiang-peng 2006Chinese Medical Journal2006,,16:6
