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
2Resveratrol provides neuroprotection by regulating the JAK2/STAT3/PI3K/AKT/mTOR pathway after stroke in rats显示文摘Ischemic stroke is a common disease with high mortality and morbidity worldwide.One of the important pathophysiological effects of ischemic stroke is apoptosis.A neuroprotective effect is defined as the inhibition of neuronal apoptosis to rescue or delay the infarction in the surviving ischemic penumbra.Resveratrol is a natural polyphenol that reportedly prevents cerebral ischemia injury by regulating the expression of PI3K/AKT/mTOR.Therefore,this study aimed to elucidate the neuroprotective effect of resveratrol on cerebral ischemia/reperfusion injury and to investigate the signaling pathways and mechanisms through which resveratrol regulates apoptosis in the ischemic penumbra.Rats were subjected to middle cerebral artery occlusion for 2 h followed by 24 h reperfusion.Cerebral infarct volume was measured using 2%TTC staining.TUNEL staining was conducted to evaluate neuronal apoptosis.Western blotting and immunohistochemistry were used to detect the proteins involved in the JAK2/STAT3/PI3K/AKT/mTOR pathway.The results suggested that resveratrol significantly improved neurological function,reduced cerebral infarct volume,decreased neuronal damage,and markedly attenuated neuronal apoptosis;these effects were attenuated by the inhibition of PI3K/AKT with LY294002 and JAK2/STAT3 with AG490.We also found that resveratrol significantly upregulated the expression of p-JAK2,p-STAT3,p-AKT,p-mTOR,and BCL-2 and downregulated expression of cleaved caspase-3 and BAX,which was partially reversed by LY294002 and AG490.These results suggested that resveratrol provides a neuroprotective effect against cerebral ischemia/reperfusion injury,which is partially mediated by the activation of JAK2/STAT3 and PI3K/AKT/mTOR.Resveratrol may indirectly upregulate the PI3K/AKT/mTOR pathway by activating JAK2/STAT3.Yongying Hou Ke Wang Weijun Wan Yue Cheng Xia Pu Xiufeng Ye 2018Genes & Diseases2018,5,3:60
3Deep carbon cycles constrained by a large-scale mantle Mg isotope anomaly in eastern China显示文摘Although deep carbon recycling plays an important role in the atmospheric CO_2 budget and climate changes through geological time,the precise mechanisms remain poorly understood.Since recycled sedimentary carbonate through plate subduction is the main light-δ^(26)Mg reservoir within deep-Earth,Mg isotope variation in mantle-derived melts provides a novel perspective when investigating deep carbon cycling.Here,we show that the Late Cretaceous and Cenozoic continental basalts from 13 regions covering the whole of eastern China have low δ^(26)Mg isotopic compositions,while the Early Cretaceous basalts from the same area and the island arc basalts from circum-Paciic subduction zones have mantle-like or heavy Mg isotopic characteristics.hus,a large-scale mantle low δ^(26)Mg anomaly in eastern China has been delineated,suggesting the contribution of sedimentary carbonates recycled into the upper mantle,but limited into the lower mantle.his large-scale spatial and temporal variation of Mg isotopes in the mantle places severe constraints on deep carbon recycling via oceanic subduction.Shu-Guang Li Wei Yang Shah Ke Xunan Meng Hengci Tian Lijuan Xu Yongsheng He Jian Huang Xuan-Ce Wang Qunke Xia Weidong Sun Xiaoyong Yang Zhong-Yuan Ren Haiquan Wei Yongsheng Liu Fancong Meng Jun Yan 2017National Science Review2017,4,1:23
4Association between Ambient Air Pollution and Hospital Emergency Admissions for Respiratory and Cardiovascular Diseases in Beijing: a Time Series Study显示文摘Objective To investigate the association between ambient air pollution and hospital emergency admissions in Beijing. Methods In this study, a semi-parametric generalized additive model(GAM) was used to evaluate the specific influences of air pollutants(PM10, SO2, and NO2) on hospital emergency admissions with different lag structures from 2009 to 2011, the sex and age specific influences of air pollution and the modifying effect of seasons on air pollution to analyze the possible interaction. Results It was found that a 10 μg/m3 increase in concentration of PM10 at lag 03 day, SO2 and NO2 at lag 0 day were associated with an increase of 0.88%, 0.76%, and 1.82% respectively in overall emergency admissions. A 10 μg/m3 increase in concentration of PM10, SO2 and NO2 at lag 5 day were associated with an increase of 1.39%, 1.56%, and 1.18% respectively in cardiovascular disease emergency admissions. For lag 02, a 10 μg/m3 increase in concentration of PM10, SO2 and NO2 were associated with 1.72%, 1.34%, and 2.57% increases respectively in respiratory disease emergency admissions. Conclusion This study further confirmed that short-term exposure to ambient air pollution was associated with increased risk of hospital emergency admissions in Beijing.ZHANG Ying WANG Shi Gong MA Yu Xia SHANG Ke Zheng CHENG Yi Fan LI Xu NING Gui Cai ZHAO Wen Jing LI Nai Rong 2015Biomedical and Environmental Sciences2015,28,5:18
5Fossils of Quercus sect. Heterobalanus can help explain the uplift of the Himalayas显示文摘Using data from previous research on Quercus sect. Heterobalanus, the coexistence approach to Xix-abangma and Namling fossil sets, and altitudinal ranges of vegetation presented by fossil floras, a re-view and reevaluation have been made of existing theories on the uplift of the Himalayas, especially the palaeoaltitudes of Xixabangma and Namling in Tibet. The Xixabangma fossil set has a palaeoaltitude range of 2500―3500 m, and has risen 2200―3400 m since the Pliocene. The lower and upper assem-blages of the Miocene Namling had palaeoaltitudes of 2500―3000 m and 2800―3000 m, respectively. Therefore, Namling has risen at least 1300 m since the Miocene, thereby challenging some existing theories that suggest Namling has been static since the Miocene.ZHOU ZheKun YANG QingSong XIA Ke 2007Chinese Science Bulletin2007,52,2:16

8Estimating the crop leaf area index using hyperspectral remote sensing显示文摘The leaf area index(LAI) is an important vegetation parameter,which is used widely in many applications.Remote sensing techniques are known to be effective but inexpensive methods for estimating the LAI of crop canopies.During the last two decades,hyperspectral remote sensing has been employed increasingly for crop LAI estimation,which requires unique technical procedures compared with conventional multispectral data,such as denoising and dimension reduction.Thus,we provide a comprehensive and intensive overview of crop LAI estimation based on hyperspectral remote sensing techniques.First,we compare hyperspectral data and multispectral data by highlighting their potential and limitations in LAI estimation.Second,we categorize the approaches used for crop LAI estimation based on hyperspectral data into three types:approaches based on statistical models,physical models(i.e.,canopy reflectance models),and hybrid inversions.We summarize and evaluate the theoretical basis and different methods employed by these approaches(e.g.,the characteristic parameters of LAI,regression methods for constructing statistical predictive models,commonly applied physical models,and inversion strategies for physical models).Thus,numerous models and inversion strategies are organized in a clear conceptual framework.Moreover,we highlight the technical difficulties that may hinder crop LAI estimation,such as the 'curse of dimensionality' and the ill-posed problem.Finally,we discuss the prospects for future research based on the previous studies described in this review.LIU Ke ZHOU Qing-bo WU Wen-bin XIA Tian TANG Hua-jun 2016Journal of Integrative Agriculture2016,15,2:14

10Downregulation of serum mi R-17 and mi R-106b levels in gastric cancer and benign gastric diseases显示文摘Altered micro RNA(mi RNA) associated with gastric cancer(GC) development and mi R-17 and mi R-106 b were differentially expressed in GC tissues. This study detected serum levels of mi R-17 and mi R-106 b expression in GC, benign gastric disease(BGD) and healthy controls to assess them as tumor markers for GC. Serum samples from 40 GC, 32 BGD(10 gastric ulcer, 14 gastric polyps, and 8 gastric ulcer with polyps) and 36 healthy individuals were subjected to quantitative reverse transcription polymerase chain reaction(q RT-PCR) analysis of mi R-17 and mi R-106 b expression. The data showed that the serum levels of mi R-17 and mi R-106 b were significantly reduced in healthy individuals and BGD patients compared to GC patients. There was a significant association of mi R-17 and mi R-106 b expression with age, but not with other clinicopathological features, such as gender, tumor differentiation, stage and lymphatic metastasis. Further analysis showed that, in discriminating GC patients from healthy controls, mi R-17 could yield a receiver-operating characteristic(ROC) area under the curve(AUC) of 0.879 with 80.6% sensitivity and 87.5% specificity and mi R-106 b could yield an AUC of 0.856 with 75.0% sensitivity and 92.5% specificity. The combined AUC of mi R-17 and mi R-106 b was 0.913 with 83.3% sensitivity and 87.5% specificity. Collectively, these data suggest that detection of serum mi R-17 and mi R-106 b levels should be further evaluated as novel non-invasive biomarkers in early GC detection and surveillance of disease progression.Qinghai Zeng Cuihong Jin Wenhang Chen Fang Xia Qi Wang Fan Fan Juan Du Yihang Guo Changwei Lin Kaiyan Yang Jingjing Li Xiaowei Peng Xiaorong Li Ke Cao 2014Chinese Journal of Cancer Research2014,26,6:12

14Evaluation of Ultrasound-guided Genitofemoral Nerve Block Combined with Ilioinguinal/iliohypogastric Nerve Block during Inguinal Hernia Repair in the Elderly显示文摘To evaluate the anesthetic effect of ultrasound-guided(USG)ilioinguinal/iliohypogastric nerve(Ⅱ/IHN)block combined with genital branch of genitofemoral nerve(GFN)block in the elderly undergoing inguinal hernia repair,54 old patients(aged 60-96years,ASAⅠ-Ⅲ)with indirect hernia were enrolled and scheduled for unilateral tensiofree herniorrhaphy.Patients were grouped randomly to receive either USGⅡ/IHN plus GFN block(Group G)or USGⅡ/IHN block alone(GroupⅠ).The intraoperative visual analogue scale(VAS)scores were recorded at skin incision,at spermatic cord/round ligament traction and at sac ligation.The resting and dynamic VAS scores were recorded postoperatively.The requirements of extra sedatives and analgesics for intra-and postoperative analgesia were assessed.Occurrence of complications of the block,postoperative nausea and vomiting and femoral nerve palsy was also reported.Both groups showed similar sensory block.When stretching spermatic cord/round ligament,the patients in group G had significantly lower VAS scores than in group.And group G used much fewer adjuvant sedatives and analgesics to achieve adequate anaesthesia.In addition,group G was presented with better intraoperative anaesthesia and lower postoperative dynamic VAS scores at all time points tested.No significant difference was found in the postoperative requirement of rescue medication.Both groups showed no complications related to the block and group G reported no femoral nerve palsy.The addition of GFN block toⅡ/IHN block improves the quality of perioperative anesthesia and analgesia in the elderly and reduces the consumption of extra sedatives and analgesics during the surgery.Zhi HUANG Wei XIA Xiao-hong PENG Jin-yuan KE Wei WANG 2019Current Medical Science2019,39,5:10
15Development and validation of an endoscopic images-based deep learning model for detection with nasopharyngeal malignancies显示文摘Background:Due to the occult anatomic location of the nasopharynx and frequent presence of adenoid hyperpla-sia,the positive rate for malignancy identification during biopsy is low,thus leading to delayed or missed diagnosis for nasopharyngeal malignancies upon initial attempt.Here,we aimed to develop an artificial intelligence tool to detect nasopharyngeal malignancies under endoscopic examination based on deep learning.Methods:An endoscopic images-based nasopharyngeal malignancy detection model(eNPM-DM)consisting of a fully convolutional network based on the inception architecture was developed and fine-tuned using separate training and validation sets for both classification and segmentation.Briefly,a total of 28,966 qualified images were collected.Among these images,27,536 biopsy-proven images from 7951 individuals obtained from January 1st,2008,to December 31st,2016,were split into the training,validation and test sets at a ratio of 7:1:2 using simple randomiza-tion.Additionally,1430 images obtained from January 1st,2017,to March 31st,2017,were used as a prospective test set to compare the performance of the established model against oncologist evaluation.The dice similarity coef-ficient(DSC)was used to evaluate the efficiency of eNPM-DM in automatic segmentation of malignant area from the background of nasopharyngeal endoscopic images,by comparing automatic segmentation with manual segmenta-tion performed by the experts.Results:All images were histopathologically confirmed,and included 5713(19.7%)normal control,19,107(66.0%)nasopharyngeal carcinoma(NPC),335(1.2%)NPC and 3811(13.2%)benign diseases.The eNPM-DM attained an overall accuracy of 88.7%(95%confidence interval(CI)87.8%-89.5%)in detecting malignancies in the test set.In the prospective comparison phase,eNPM-DM outperformed the experts:the overall accuracy was 88.0%(95%CI 86.1%-89.6%)vs.80.5%(95%CI 77.0%-84.0%).The eNPM-DM required less time(40 s vs.110.0±5.8 min)and exhibited encouraging performance in automatic segmentation of nasopharyngeal malignant area from the background,with an average DSC of 0.78±0.24 and 0.75±0.26 in the test and prospective test sets,respectively.Conclusions:The eNPM-DM outperformed oncologist evaluation in diagnostic classification of nasopharyngeal mass into benign versus malignant,and realized automatic segmentation of malignant area from the background of nasopharyngeal endoscopic images.Chaofeng Li Bingzhong Jing Liangru Ke Bin Li Weixiong Xia Caisheng He Chaonan Qian Chong Zhao Haiqiang Mai Mingyuan Chen Kajia Cao Haoyuan Mo Ling Guo Qiuyan Chen Linquan Tang Wenze Qiu Yahui Yu Hu Liang Xinjun Huang Guoying Liu Wangzhong Li Lin Wang Rui Sun Xiong Zou Shanshan Guo Peiyu Huang Donghua Luo Fang Qiu Yishan Wu Yijun Hua Kuiyuan Liu Shuhui Lv Jingjing Miao Yanqun Xiang Ying Sun Xiang Guo Xing Lv 2018Cancer Communications2018,38,1:9

17Blood Pressure Associated with Arsenic Methylation and Arsenic Metabolism Caused by Chronic Exposure to Arsenic in Tube Well Water显示文摘Objective The effects of arsenic exposure from drinking water, arsenic metabolism, and arsenic methylation on blood pressure(BP) were observed in this study. Methods The BP and arsenic species of 560 participants were determined. Logistic regression analysis was applied to estimate the odds ratios of BP associated with arsenic metabolites and arsenic methylation capability. Results BP was positively associated with cumulative arsenic exposure(CAE). Subjects with abnormal diastolic blood pressure(DBP), systolic blood pressure(SBP), and pulse pressure(PP) usually had higher urinary i As(inorganic arsenic), MMA(monomethylated arsenic), DMA(dimethylated arsenic), and TAs(total arsenic) than subjects with normal DBP, SBP, and PP. The i As%, MMA%, and DMA% differed slightly between subjects with abnormal BP and those with normal BP. The PMI and SMI were slightly higher in subjects with abnormal PP than in those with normal PP. Conclusion Our findings suggest that higher CAE may elevate BP. Males may have a higher risk of abnormal DBP, whereas females have a higher risk of abnormal SBP and PP. Higher urinary i As may increase the risk of abnormal BP. Lower PMI may elevate the BP. However, higher SMI may increase the DBP and SBP, and lower SMI may elevate the PP.WEI Bing Gan YE Bi Xiong YU Jiang Ping YANG Lin Sheng LI Hai Rong XIA Ya Juan WU Ke Gong 2017Biomedical and Environmental Sciences2017,30,5:9
18BubR1 phosphorylates CENP-E as a switch enabling the transition from lateral association to end-on capture of spindle microtubules显示文摘Error-free mitosis depends on accurate chromosome attachment to spindle microtubules, powered congression of those chromosomes, their segregation in anaphase, and assembly of a spindle midzone at mitotic exit. The centromere-associated kinesin motor CENP-E, whose binding partner is BubR1, has been implicated in congression of misaligned chromosomes and the transition from lateral kinetochore-microtubule association to end-on capture. Although previously proposed to be a pseudokinase, here we report the structure of the kinase domain of Drosophila melanogaster BubR1, revealing its folding into a conformation predicted to be catalytically active. BubR1 is shown to be a bona fide kinase whose phosphorylation of CENP-E switches it from a laterally attached microtubule motor to a plus-end microtubule tip tracker. Computational modeling is used to identify bubristatin as a selective BubR1 kinase antagonist that targets the αN1 helix of N-terminal extension and αC helix of the BubR1 kinase domain. Inhibition of CENP-E phosphorylation is shown to prevent proper microtubule capture at kinetochores and, surprisingly, proper assembly of the central spindle at mitotic exit. Thus, BubR1-mediated CENP-E phosphorylation produces a temporal switch that enables transition from lateral to end-on microtubule capture and organization of microtubules into stable midzone arrays.Yuejia Huang Lin Lin Xing Liu Sheng Ye Phil Y.

19Combined effects of p53 and MDM2 polymorphisms on susceptibility and surgical prognosis in hepatitis B virus-related hepatocellular carcinoma显示文摘The p53 signaling pathway works as a potent barrier to tumor progression.Two single nucleotide polymor-phisms(SNPs)in the gene loci of p53 pathway,p53 codon 72 Arg72Pro and MDM2 SNP309(T>G),have been shown to cause perturbation of p53 function,but the effect of the two SNPs on the risk of hepatocellular carcinoma(HCC)remains inconsistent.This study in-vestigated the influence of combined p53 Arg72Pro and MDM2 SNP309 on the risk of developing HCC in pa-tients with chronic hepatitis B virus infection,and evaluated the significance of the two combined SNPs on patient prognosis.In total,350 HCC patients,230 non-HCC patients,and 96 healthy controls were geno-typed for the p53 Arg72Pro and MDM2 SNP309.The combined p53 Pro/Pro and MDM2 G/G genotype was significantly associated with HCC risk(P=0.047).Mul-tivariate analysis indicated that combined p53 Pro/Pro and MDM2 G/G genotype was an independent factor affecting recurrence and survival(P<0.05).Patients with combined p53 Pro/Pro and MDM2 G/G genotypes had a poorer prognosis than other genotypes,P<0.01 for both disease-free survival(DFS)and overall survival(OS).DFS and OS rates also differed significantly be-tween Barcelona Clinic Liver Cancer(BCLC)stage A patients with combined p53 Pro/Pro and MDM2 G/G and other genotypes(P<0.05).Thus,the combined p53 Pro/Pro and MDM2 G/G genotype is associated with increased risk of developing HCC and is an independ-ent adverse prognostic indicator in early stage HCC.Yun Yang Tian Xia Ning Li Jin Zhang Yuan Yang Wenming Cong Qiang Deng Ke Lan Weiping Zhou 2013Protein & Cell2013,4,1:8
