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
2Efficacy of cattle encephalon glycoside and ignotin in patients with acute cerebral infarction: a randomized, double-blind, parallel-group, placebo-controlled study显示文摘Cattle encephalon glycoside and ignotin(CEGI)injection is a compound preparation formed by a combination of muscle extract from hea lthy rabbits and brain gangliosides from cattle,and it is generally used as a neuroprotectant in the treatment of central and peripheral nerve injuries.However,there is still a need for high-level clinical evidence from large samples to support the use of CEGI.We therefore carried out a prospective,multicenter,randomized,double-blind,parallel-group,placebo-controlled study in which we recruited 319 patients with acute cerebral infarction from 16 centers in China from October 2013 to May 2016.The patients were randomized at a 3:1 ratio into CEGI(n=239;155 male,84 female;61.2±9.2 years old)and placebo(n=80;46 male,34 female;63.2±8.28 years old)groups.All patients were given standard care once daily for 14 days,including a 200 mg aspirin enteric-coated tablet and 20 mg atorvastatin calcium,both taken orally,and intravenous infusion of 250–500 mL 0.9%sodium chloride containing 40 mg sodium tanshinone IIA sulfonate.Based on conventional treatment,patients in the CEGI and placebo groups were given 12 mL CEGI or 12 mL sterile water,respectively,in an intravenous drip of 250 mL 0.9%sodium chloride(2 mL/min)once daily for 14 days.According to baseline National Institutes of Health Stroke Scale scores,patients in the two groups were divided into mild and moderate subgroups.Based on the modified Rankin Scale results,the rate of patients with good outcomes in the CEGI group was higher than that in the placebo group,and the rate of disability in the CEGI group was lower than that in the placebo group on day 90 after treatment.In the CEGI group,neurological deficits were decreased on days 14 and 90 after treatment,as measured by the National Institutes of Health Stroke Scale and the Barthel Index.Subgroup analysis revealed that CEGI led to more significant improvements in moderate stroke patients.No drug-related adverse events occurred in the CEGI or placebo groups.In conclusion,CEGI may be a safe and effective treatment for acute cerebral infarction patients,especially for moderate stroke patients.This study was approved by the Ethical Committee of Peking University Third Hospital,China(approval No.2013-068-2)on May 20,2013,and registered in the Chinese Clinical Trial Registry(registration No.ChiCTR1800017937).Hui Zhang Chuan-Ling Li Feng Wan Su-Juan Wang Xiu-E Wei Yan-Lei Hao Hui-Lin Leng Jia-Min Li Zhong-Rui Yan Bao-Jun Wang Ren-Shi Xu Ting-Min Yu Li-Chun Zhou Dong-Sheng Fan 2020Neural Regeneration Research2020,15,7:54
3Molecular and Biochemical Evidence for Phenylpropanoid Synthesis and Presence of Wall-linked Phenolics in Cotton Fibers显示文摘The mature cotton (Gossypium hirsutum L.) fiber is a single cell with a typically thickened secondary cell wall. The aim of this research was to use molecular, spectroscopic and chemical techniques to investigate the possible occurrence of previously overlooked accumulation of phenolics during secondary cell wall formation in cotton fibers. Relative quantitative reverse transcription-polymerase chain reaction analysis showed that GhCAD6 and GhCAD1 were predominantly expressed among seven gene homologs, only GhCAD6 was up-regulated during secondary wall formation in cotton fibers. Phylogenic analysis revealed that GhCAD6 belonged to Class I and was proposed to have a major role in monolignol biosynthesis, and GhCAD1 belonged to Class Ⅲ and was proposed to have a compensatory mechanism for monolignol biosynthesis. Amino acid sequence comparison showed that the cofactor binding sites of GhCADs were highly conserved with high similarity and identity to bona fide cinnamyl alcohol dehydrogenases. The substrate binding site of GhCAD1 is different from GhCAD6. This difference was confirmed by the different catalytic activities observed with the enzymes. Cell wall auto-fluorescence, Fourier transform infrared spectroscopy (FTIR), high-performance liquid chromatography (HPLC) and chemical analyses confirmed that phenolic compounds were bound to the cell walls of mature cotton fibers. Our findings may suggest a potential for genetic manipulation of cotton fiber properties, which are of central importance to agricultural, cotton processing and textile industries.Ling Fan Wei-Jun Shi Wen-Ran Hu Xinn-Ynn Hao Dong-Mei Wang Hui Yuan Hong-Ying Yan 2009Journal of Integrative Plant Biology2009,51,7:47

5Deferoxamine promotes recovery of traumatic spinal cord injury by inhibiting ferroptosis显示文摘Ferroptosis is an iron-dependent novel cell death pathway. Deferoxamine, a ferroptosis inhibitor, has been reported to promote spinal cord injury repair. It has yet to be clarified whether ferroptosis inhibition represents the mechanism of action of Deferoxamine on spinal cord injury recovery. A rat model of Deferoxamine at thoracic 10 segment was established using a modified Allen's method. Ninety 8-week-old female Wistar rats were used. Rats in the Deferoxamine group were intraperitoneally injected with 100 mg/kg Deferoxamine 30 minutes before injury. Simultaneously, the Sham and Deferoxamine groups served as controls. Drug administration was conducted for 7 consecutive days. The results were as follows:(1) Electron microscopy revealed shrunken mitochondria in the spinal cord injury group.(2) The Basso, Beattie and Bresnahan locomotor rating score showed that recovery of the hindlimb was remarkably better in the Deferoxamine group than in the spinal cord injury group.(3) The iron concentration was lower in the Deferoxamine group than in the spinal cord injury group after injury.(4) Western blot assay revealed that, compared with the spinal cord injury group, GPX4, xCT, and glutathione expression was markedly increased in the Deferoxamine group.(5) Real-time polymerase chain reaction revealed that, compared with the Deferoxamine group, mRNA levels of ferroptosis-related genes Acyl-CoA synthetase family member 2(ACSF2) and iron-responsive element-binding protein 2(IREB2) were up-regulated in the Deferoxamine group.(6) Deferoxamine increased survival of neurons and inhibited gliosis. These findings confirm that Deferoxamine can repair spinal cord injury by inhibiting ferroptosis. Targeting ferroptosis is therefore a promising therapeutic approach for spinal cord injury.Xue Yao Yan Zhang Jian Hao Hui-Quan Duan Chen-Xi Zhao Chao Sun Bo Li Bao-You Fan Xu Wang Wen-Xiang Li Xuan-Hao Fu Yong Hu Chang Liu Xiao-Hong Kong Shi-Qing Feng 2019Neural Regeneration Research2019,14,3:35
6Volumetric-modulated arc therapy vs c-IMRT in esophageal cancer:A treatment planning comparison显示文摘AIM:To compare the volumetric-modulated arc therapy AT plans ith conventional sliding indo intensity-modulated radiotherapy c-I RT plans in esophageal cancer EC . METHODS:Tenty patients ith EC ere selected, including 5 cases located in the cervical, the upper, the middle and the lo er thorax, respectively. Five plans ere generated ith the eclipse planning system:three using c-IMRT with 5 fields (5F), 7 fields (7F) and 9 fields (9F), and two using VMAT with a single arc 1A and double arcs 2A . The treatment plans ere designed to deliver a dose of 60 Gy to the plan-ning target volume Tith the same constrains in a 2.0 Gy daily fraction, 5 d a eek. lans ere normalized to 95% of the T that received 100% of the prescribed dose. We examined the dose-volume histogram parameters of T and the organs at risk OAR such as lungs, spinal cord and heart. onitor units U and normal tissue complication probability NTC of OAR ere also reported. RESULTS:Both c-I RT and AT plans resulted in abundant dose coverage of T for EC of different locations. The dose conformity to T as improved as the number of field in c-IMRT or rotating arc in VMAT as increased. The doses to T and OAR in AT plans ere not statistically different in comparison ith c-I RT plans, ith the follo ing exceptions:in cervical and upper thoracic EC, the conformity index CI as higher in VMAT (1A 0.78 and 2A 0.8) than in c-IMRT (5F 0.62, 7F 0.66 and 9F 0.73) and homogeneity was slightly better in c-IMRT (7F 1.09 and 9F 1.07) than in VMAT (1A 1.1 and 2A 1.09). Lung V30 was lower in VMAT (1A 12.52 and 2A 12.29) than in c-IMRT (7F 14.35 and 9F 14.81). The humeral head doses were significantly increased in AT as against c-I RT. In the middle and lower thoracic EC, CI in VMAT (1A 0.76 and 2A 0.74) was higher than in c-IMRT (5F 0.63 Gy and 7F 0.67 Gy), and homogeneity was almost similar bet een AT and c-I RT. 20 2A 21.49 Gy vs 7F 24.59 Gy and 9F 24.16 Gy) and V30 (2A 9.73 Gy vs 5F 12.61 Gy, 7F 11.5 Gy and 9F 11.37 Gy) of lungs in AT ere lo er than in c-I RT, but lo doses to lungs (V5 and V10) were increased. V30 (1A 48.12 Gy vs 5F 59.2 Gy, 7F 58.59 Gy and 9F 57.2 Gy), V40 and 50 of heart in AT as lo er than in c-I RT. Us in AT plans ere significantly reduced in comparison ith c-I RT, maximum doses to the spinal cord and mean doses of lungs ere similar bet een the t o techniques. NTC of spinal cord as 0 for all cases. NTC of lungs and heart in AT ere lo er than inc-I RT. The advantage of AT plan as enhanced by doubling the arc. CONCLUSION:Compared ith c-I RT, AT, especially the 2A, slightly improves the OAR dose sparing, such as lungs and heart, and reduces NTC and U ith a better T coverage.Li Yin Hao Wu Jian Gong Jian-Hao Geng Fan Jiang An-Hui Shi Rong Yu Yong-Heng Li Shu-Kui Han Bo Xu Guang-Ying Zhu 2012World Journal of Gastroenterology2012,18,37:34

8Biological properties and clinical applications of berberine显示文摘Berberine,an isoquinoline alkaloid isolated from the Chinese herb Coptis chinens is and other Berber is plants,has a wide range of pharmacological properties.Berberine can be used to treat many diseases,such as cancer and digestive,metabolic,cardiovascular,and neurological diseases.Berberine has protective capacities in digestive diseases.It can inhibit toxins and bacteria,including Helicobac terpylo riprotect the intestinal epithelial barrier from injury,and ameliorate liver injury.Berberine also inhibits the proliferation of various types of cancer cells and impedes invasion and metastasis.Recent evidence has confirmed that berberine improves the efficacy and safety of chemoradiotherapies.In addition,berberine regulates glycometabolism and lipid metabolism,improves energy expenditure,reduces body weight,and alleviates nonalcoholic fatty liver disease.Berberine also improves cardiovascular hemodynamics,suppresses ischemic arrhythmias,attenuates the development of atherosclerosis,and reduces hypertension.Berberine shows potent neuroprotective effects,including antioxidative,antiapoptotic,and anti-ischemic.Furthermore,berberine exerts protective effects against other diseases.The mechanisms of its functions have been extensively explored,but much remains to be clarified.This article summarizes the main pharmacological actions of berberine and its mechanisms in cancer and digestive,metabolic,cardiovascular,and neurological diseases.Danyang Song Jianyu Hao Daiming Fan 2020Frontiers of Medicine2020,14,5:30
9Wheat Grain Yield and Yield Stability in a Long-Term Fertilization Experiment on the Loess Plateau显示文摘To provide a scientific basis for sustainable land management, a 20-year fertility experiment was conducted in Changwu County, Shaanxi Province, China to investigate the effects of long-term application of chemical fertilizers on wheat grain yield and yield stability on the Loess Plateau using regression and stability analysis. The experiment consisted of 17 fertilizer treatments, containing the combinations of different N and P levels, with three replications arranged in a randomized complete block design. Nitrogen fertilizer was applied as urea, and P was applied as calcium superphosphate. Fertilizer rates had a large effect on the response of wheat yield to fertilization. Phosphorus, combined with N, increased yield significantly (P < 0.01). In the unfertilized control and the N or P sole application treatments, wheat yield had a declining trend although it was not statistically significant. Stability analysts combined with the trend analysis indicated that integrated use of fertilizer N and P was better than their sole application in increasing and sustaining the productivity of rainfed winter wheat.HAO Ming-De FAN Jun WANG Quan-Jiu DANG Ting-Hui GUO Sheng-Li WANG Ji-Jun 2007Pedosphere2007,17,2:28
10Nitrate Accumulation in Soil Profile of Dry Land Farming in Northwest China显示文摘A long-term fertilizer experiment on dry land of the Loess Plateau, northwest China, has been conducted since 1984 to study the distribution and accumulation of NO3-N down to a depth of 400 cm in the profile of a coarse-textured dark loessial soil after continuous winter wheat cropping. Thirteen fertilizer treatments consisted of four levels of N and P applied alone or in combination. Annual N and P (P2O5) rates were 0,45, 90, 135 and 180 kg ha-1. After 15 successive cropping cycles, the soil samples were taken from each treatment for analysis of NO3-N concentration. The results showed that NO3-N distribution in the soil profile was quite different among the treatments. The application of fertilizer N alone resulted in higher NO3-N concentration in the soil profile than the combined application of N and P, showing that application of P could greatly reduce the NO3-N accumulation. With an annual application of 180 kg N ha-1 alone, a peak in NO3-N accumulation occurred at 140 cm soil depth, and the maximum NO3-N concentration in the soils was 67.92 mg kg-1. The amount of NO3-N accumulated in the soil profile decreased as the cumulative N uptake by the winter wheat increased. Application of a large amount of N resulted in lower N recoveries in winter wheat and greater NO3-N accumulation in soil profile. NO3-N did not enter underground water in the study region; therefore, there is no danger of underground water pollution. Amount of NO3-N accumulation can be predicted by an equation according to annual N and P rates based on the results of this experiment.FAN Jun, HAO Ming-De and SHAO Ming-AnState Key Laboratory of Soil Erosion and Dryland Farming on the Loess Plateau, Institute of Soil and Water Conservation, the Chinese Academy of Sciences, Yangling 712100 (China). 2003Pedosphere2003,13,4:25

15Safety Research in Traditional Chinese Medicine: Methods, Applications, and Outlook显示文摘Traditional Chinese medicine (TCM) is a medical system that has collected and summarized abundant clinical experience over its long history of more than 2000 years. However, the frequent occurrence of TCM-induced adverse reactions has hindered the modernization and internationalization of TCM, while attracting increasing attention from around the world. Unlike chemical drugs and biological agents, the difficulties involved in research on the toxicity and safety of TCM mainly include the complexity of its components and the unpredictability of drug–body interactions. Much of TCM, which has overall therapeutic effects, has the typical mechanisms of multiple components, multiple pathways, and multiple targets. While considering the gradualness and unpredictability of TCM toxicity, the ambiguity of toxicants and safe dosage, and individual differences during long-term TCM administration, we have systematically established key techniques for the toxicity assessment of TCM. These techniques mainly include TCM toxicity discovery in an early phase, based on a combination of drug toxicology genomics and metabolomics;methods to identify dose–toxicity relationships in TCM;and integrated techniques for the exploration of TCM interactions, such as fast-screening tests based on drug-metabolizing enzymes and receptor pathways. In particular, we have developed a new technical system for TCM safety evaluation using molecular toxicology, which has been validated well in research on TCM compatibility contraindication, quality control, and allergen discovery. The application of this key technical platform is introduced here in detail. This application includes model organisms, toxicant biomarkers, a magnetic suspension technique, and the application of network toxicology and computational toxicology in research on the toxicity of Fructus toosendan, Semen cassiae, Polygonum multiflorum, and Fructus psoraleae.Yue Gao Aihua Liang Xiaohui Fan Limin Hu Feiran Hao Yubo Li 2019Engineering2019,5,1:19

17Near-infrared responsive 5-fluorouracil and indocyanine green loaded MPEG-PCL nanoparticle integrated with dissolvable microneedle for skin cancer therapy显示文摘The prevalence of skin cancer is rising along with the rapid population aging in recent years.Traditional therapies,such as surgical treatment,radiotherapy,chemotherapy,photodynamic therapy,and immunotherapy,may accompany serious side effects,limiting their clinical benefits.According to the biological characteristics of skin cancer,we have already established two kinds of synergetic systems of photothermal therapy(microneedle)and chemotherapy,containing gold nanorods(GNR).Although the microneedle system exhibited great potential for skin cancer treatment,the system could be still improved further.So,we designed a near-infrared lightresponsive 5-fluorouracil(5-Fu)and indocyanine green(ICG)loaded monomethoxy-poly(ethylene glycol)-polycaprolactone(MPEG-PCL)nanoparticle(5-Fu-ICG-MPEG-PCL),and then 5-Fu-ICG-MPEG-PCL was integrated with a hyaluronic acid dissolvable microneedle system(HA MN)to get 5-Fu-ICG-MPEG-PCL loaded HA MN for treating skin cancers,including human epidermoid cancer and melanoma.In this system,hyaluronic acid,the microneedle carrier,possesses good skin penetration ability and is approved by FDA as a pharmaceutical adjuvant;5-Fu is recommended by FDA for skin cancer treatment;ICG,a photothermal agent,possesses a strong photothermal ability and is approved by FDA for its use in the human body.We hypothesized that 5-Fu-ICG-MPEG-PCL could be delivered by the dissolvable microneedle through the skin,and the release behavior of the drug in the nanoparticle could be controlled by near-infrared light for achieving a single-dose cure of skin cancer,improving the cure rate of skin cancer and providing a new idea and possibility for the clinical treatment of skin cancer.Ying Hao YuWen Chen XinLong He Fan Yang RuXia Han ChengLi Yang Wei Li ZhiYong Qian 2020Bioactive Materials2020,5,3:17
18Viral infection parameters not nucleoside analogue itself correlates with host immunity in nucleoside analogue therapy for chronic hepatitis B显示文摘AIM:To determine the relationship between host immunity and the characteristics of viral infection or nucleoside analogues(NAs)themselves in patients with chronic hepatitis B(CHB)receiving NA therapy.METHODS:Fifty-two hepatitis B envelope antigen(HBeAg)positive CHB patients were enrolled and divided equally into two groups.One group received telbivudine(LDT,600 mg/d),and the other group received lamivudine(LAM,100 mg/d).Clinical,virological and immunological parameters were assessed at the baseline and at 4,12,24,36 and 48 wk.RESULTS:Both groups achieved significant hepatitis B virus(HBV)replication inhibition and alanine aminotransferase normalization at 48 wk.At the baseline,compared to healthy controls,CHB patients had a lower circulating CD8 T cell frequency(29.44%±11.55%vs 37.17%±7.30%,p=0.03)and higher frequencies of programmed death 1 positive CD8 T cells(pD-1+CD8 T)(16.48%±10.82%vs 7.02%±3.62%,p=0.0001)and CD4+CD25+Foxp3+T regulatory cells(Tregs)(23.64%±9.38%vs 13.60%±6.06%,p=0.001).On therapy,at the beginning 24 wk with the levels of hepatitis B virus deoxyribonucleic acid(HBV DNA)and HBeAg declining,the frequencies of pD-1+CD8 T cells and Treg cells gradually and significantly declined at 12 and 24 wk in both therapy groups.At treatment week 4,patients treated with LDT had a lower frequency of pD-1+CD8 T cells compared to patients treated with LAM(10.08%±6.83%vs 20.51%±20.96%,p=0.02).The frequency of pD-1+CD8 T cells in all of the CHB patients was significantly correlated with both the HBV DNA level(r=0.45,p=0.01)and HBeAg level(r=0.47,p=0.01)at treatment week 24,but the frequency of Treg cells was only significantly correlated with the HBeAg level(r=0.44,p=0.02).Furthermore,the ability of CD8 T cells to secrete pro-inflammatory cytokines was partially restored after 24 wk of therapy.CONCLUSION:NA-mediated HBV suppression could down-regulate the production of negative regulators of host immunity during the first 24 wk of therapy and could partially restore the ability of CD8 T cells to secrete pro-inflammatory cytokines.This immune modulating response may be correlated with the levels of both HBV DNA and HBeAg.Cheng-Zhong Li Jing-Jing Hu Jian-Ya Xue Wei Yin Ya-Yun Liu Wen-Han Fan Hao Xu Xue-Song Liang 2014World Journal of Gastroenterology2014,20,28:16
