2Mapping wetland changes in China between 1978 and 2008显示文摘Four wetland maps for all China have been produced,based on Landsat and CBERS-02B remote sensing data between 1978 and 2008 (1978,1990,2000 and 2008).These maps were mainly developed by manual interpretation and validated by substantial field investigation in 2009.Based on these maps,we analyzed the 2008 wetland distribution in China and discussed wetland changes and their drivers over the past 30 years.(i) There were about 324097 km 2 of wetlands in 2008,for which inland marshes or swamps were the most common wetland type (35%),with lakes (26%) second.Most of the wetlands were in Heilongjiang,Inner Mongolia,Qinghai and Tibet,occupying about 55% of the national wetland area.(ii) From 1978 to 2008,China's wetland area continually and significantly decreased,by about 33% based on changes in the wetland map.This was in sharp contrast to the increase in artificial wetlands,which increased by about 122%.Inland marshes accounted for the main loss of total wetlands from 1978 to 2000.From 2000 through 2008,riverine and lacustrine wetlands constituted the main wetland loss.Fortunately however,the rate of wetland loss decreased from 5523 to 831 km 2 /a.(iii) The change ratio of lost natural wetlands (including inland and coastal wetlands) to non-wetlands has decreased slightly over the past 30 years.From 1978 to 1990,nearly all natural wetlands (98%) lost were transformed into non-wetlands.However,the ratio declined to 86% from 1990 to 2000,and to 77% from 2000 to 2008.(iv) All Chinese provinces were divided into three groups according to patterns of wetland changes,which could relate to the driving forces of such changes.Tibet was completely different from other provinces,as it was one representative example in which there was a net wetland increase,because of global warming and decreased human activity since 1990.Increased economic development caused considerable wetland loss in most eastern provinces,and artificial wetlands increased.NIU ZhenGuo ZHANG HaiYing WANG XianWei YAO WenBo ZHOU DeMin ZHAO KuiYi ZHAO Hui LI NaNa HUANG HuaBing LI CongCong YANG Jun LIU CaiXia LIU Shuang WANG Lin LI Zhan YANG ZhenZhong QIAO Fei ZHENG YaoMin CHEN YanLei SHENG YongWei GAO XiaoHong ZHU WeiHong WANG WenQing WANG Hong WENG YongLing ZHUANG DaFang LIU JiYuan LUO ZhiCai CHENG Xiao GUO ZiQi GONG Peng 2012Chinese Science Bulletin2012,57,22:51

5Field experiment on a robust hierarchical metropolitan quantum cryptography network显示文摘A hierarchical metropolitan quantum cryptography network upon the inner-city commercial telecom fiber cables is reported in this paper. The seven-user network contains a four-node backbone net with one node acting as the subnet gateway, a two-user subnet and a single-fiber access link, which is realized by the Faraday-Michelson interferometer set-ups. The techniques of the quantum router, optical switch and trusted relay are assembled here to guarantee the feasibility and expandability of the quantum cryptography network. Five nodes of the network are located in the government departments and the secure keys generated by the quantum key distribution network are utilized to encrypt the instant video, sound, text messages and confidential files transmitting between these bureaus. The whole implementation including the hierarchical quantum cryptographic communication network links and the corresponding application software shows a big step toward the practical user-oriented network with a high security level.XU FangXing CHEN Wei WANG Shuang YIN ZhenQiang ZHANG Yang LIU Yun ZHOU Zheng ZHAO YiBo LI HongWei LIU Dong HAN ZhengFu GUO GuangCan 2009Chinese Science Bulletin2009,54,17:40

7Andrographolide sulfonate ameliorates lipopolysaccharide-induced acute lung injury in mice by down-regulating MAPK and NF-κB pathways显示文摘Acute lung injury(ALI) or acute respiratory distress syndrome(ARDS) is a severe, lifethreatening medical condition characterized by widespread inflammation in the lungs, and is a significant source of morbidity and mortality in the patient population. New therapies for the treatment of ALI are desperately needed. In the present study, we examined the effect of andrographolide sulfonate, a water-soluble form of andrographolide(trade name: Xi-Yan-Ping Injection), on lipopolysaccharide(LPS)-induced ALI and inflammation. Andrographolide sulfonate was administered by intraperitoneal injection to mice with LPS-induced ALI. LPS-induced airway inflammatory cell recruitment and lung histological alterations were significantly ameliorated by andrographolide sulfonate. Protein levels of pro-inflammatory cytokines in bronchoalveolar lavage fluid(BALF) and serum were reduced by andrographolide sulfonate administration. m RNA levels of pro-inflammatory cytokines in lung tissue were also suppressed. Moreover, andrographolide sulfonate markedly suppressed the activation of mitogen-activated protein kinase(MAPK) as well as p65 subunit of nuclear factor-κB(NF-κB). In summary, these results suggest that andrographolide sulfonate ameliorated LPS-induced ALI in mice by inhibiting NF-κB and MAPK-mediated inflammatory responses. Our study shows that water-soluble andrographolide sulfonate may represent a new therapeutic approach for treating inflammatory lung disorders.Shuang Peng Nan Hang Wen Liu Wenjie Guo Chunhong Jiang Xiaoling Yang Qiang Xu Yang Sun 2016Acta Pharmaceutica Sinica B2016,6,3:38
8Analysis of factors associated with disease outcomes in hospitalized patients with 2019 novel coronavirus disease显示文摘Background Since early December 2019,the 2019 novel coronavirus disease(COVID-19)has caused pneumonia epidemic in Wuhan,Hubei province of China.This study aimed to investigate the factors affecting the progression of pneumonia in COVID-19 patients.Associated results will be used to evaluate the prognosis and to find the optimal treatment regimens for COVID-19 pneumonia.Methods Patients tested positive for the COVID-19 based on nucleic acid detection were included in this study.Patients were admitted to 3 tertiary hospitals in Wuhan between December 30,2019,and January 15,2020.Individual data,laboratory indices,imaging characteristics,and clinical data were collected,and statistical analysis was performed.Based on clinical typing results,the patients were divided into a progression group or an improvement/stabilization group.Continuous variables were analyzed using independent samples t-test or Mann-Whitney U test.Categorical variables were analyzed using Chi-squared test or Fisher’s exact test.Logistic regression analysis was performed to explore the risk factors for disease progression.Results Seventy-eight patients with COVID-19-induced pneumonia met the inclusion criteria and were included in this study.Efficacy evaluation at 2 weeks after hospitalization indicated that 11 patients(14.1%)had deteriorated,and 67 patients(85.9%)had improved/stabilized.The patients in the progression group were significantly older than those in the disease improvement/stabilization group(66[51,70]vs.37[32,41]years,U=4.932,P=0.001).The progression group had a significantly higher proportion of patients with a history of smoking than the improvement/stabilization group(27.3%vs.3.0%,χ^2=9.291,P=0.018).For all the 78 patients,fever was the most common initial symptom,and the maximum body temperature at admission was significantly higher in the progression group than in the improvement/stabilization group(38.2[37.8,38.6]vs.37.5[37.0,38.4]°C,U=2.057,P=0.027).Moreover,the proportion of patients with respiratory failure(54.5%vs.20.9%,χ^2=5.611,P=0.028)and respiratory rate(34[18,48]vs.24[16,60]breaths/min,U=4.030,P=0.004)were significantly higher in the progression group than in the improvement/stabilization group.C-reactive protein was significantly elevated in the progression group compared to the improvement/stabilization group(38.9[14.3,64.8]vs.10.6[1.9,33.1]mg/L,U=1.315,P=0.024).Albumin was significantly lower in the progression group than in the improvement/stabilization group(36.62±6.60 vs.41.27±4.55 g/L,U=2.843,P=0.006).Patients in the progression group were more likely to receive high-level respiratory support than in the improvement/stabilization group(χ^2=16.01,P=0.001).Multivariate logistic analysis indicated that age(odds ratio[OR],8.546;95%confidence interval[CI]:1.628-44.864;P=0.011),history of smoking(OR,14.285;95%CI:1.577-25.000;P=0.018),maximum body temperature at admission(OR,8.999;95%CI:1.036-78.147,P=0.046),respiratory failure(OR,8.772,95%CI:1.942-40.000;P=0.016),albumin(OR,7.353,95%CI:1.098-50.000;P=0.003),and C-reactive protein(OR,10.530;95%CI:1.224-34.701,P=0.028)were risk factors for disease progression.Conclusions Several factors that led to the progression of COVID-19 pneumonia were identified,including age,history of smoking,maximum body temperature at admission,respiratory failure,albumin,and C-reactive protein.These results can be used to further enhance the ability of management of COVID-19 pneumonia.Wei Liu Zhao-Wu Tao Lei Wang Ming-Li Yuan Kui Liu Ling Zhou Shuang Wei Yan Deng Jing Liu Hui-Guo Liu Ming Yang Yi Hu 2020Chinese Medical Journal2020,,9:31
9Baicalin prevents LPS-induced activation of TLR4/NF-κB p65 pathway and inflammation in mice via inhibiting the expression of CD14显示文摘Previous studies have shown that baicalin,an active ingredient of the Chinese traditional medicine Huangqin,attenuates LPS-induced inflammation by inhibiting the activation of TLR4/NF-κBp65 pathway,but how it affects this pathway is unknown.It has been shown that CD14 binds directly to LPS and plays an important role in sensitizing the cells to minute quantities of LPS via chaperoning LPS molecules to the TLR4/MD-2 signaling complex.In the present study we investigated the role of CD14 in the anti-inflammatory effects of baicalin in vitro and in vivo.Exposure to LPS(1μg/mL)induced inflammatory responses in RAW264.7 cells,evidenced by marked increases in the expression of MHC II molecules and the secretion of NO and IL-6,and by activation of MyD88/NF-κB p65 signaling pathway,as well as the expression of CD14 and TLR4.These changes were dose-dependently attenuated by pretreatment baicalin(12.5–50μM),but not by baicalin post-treatment.In RAW264.7 cells without LPS stimulation,baicalin dose-dependently inhibit the protein and mRNA expression of CD14,but not TLR4.In RAW264.7 cells with CD14 knockdown,baicalin pretreatment did not prevent inflammatory responses and activation of MyD88/NF-κB p65 pathway induced by high concentrations(1000μg/mL)of LPS.Furthermore,baicalin pretreatment also inhibited the expression of CD14 and activation of MyD88/NF-κB p65 pathway in LPS-induced hepatocyte-derived HepG2 cells and intestinal epithelial-derived HT-29 cells.In mice with intraperitoneal injection of LPS and in DSS-induced UC mice,oral administration of baicalin exerted protective effects by inhibition of CD14 expression and inflammation.Taken together,we demonstrate that baicalin pretreatment prevents LPS-induced inflammation in RAW264.7 cells in CD14-dependent manner.This study supports the therapeutic use of baicalin in preventing the progression of LPS-induced inflammatory diseases.Ya-jun Fu Bo Xu Shao-wei Huang Xia Luo Xiang-liang Deng Shuang Luo Chang Liu Qing Wang Jin-yan Chen Lian Zhou 2021Acta Pharmacologica Sinica2021,42,1:31
10Clinical characteristics of fatal and recovered cases of coronavirus disease 2019 in Wuhan,China:a retrospective study显示文摘Background:The 2019 novel coronavirus has caused the outbreak of the acute respiratory disease in Wuhan,Hubei Province of China since December 2019.This study was performed to analyze the clinical characteristics of patients who succumbed to and who recovered from 2019 novel coronavirus disease(COVID-19).Methods:Clinical data were collected from two tertiary hospitals in Wuhan.A retrospective investigation was conducted to analyze the clinical characteristics of fatal cases of COVID-19(death group)and we compare them with recovered patients(recovered group).Continuous variables were analyzed using the Mann-WhitneyU test.Categorical variables were analyzed byχ2 test or Fisher exact test as appropriate.Results:Our study enrolled 109 COVID-19 patients who died during hospitalization and 116 recovered patients.The median age of the death group was older than the recovered group(69[62,74]vs.40[33,57]years,Z=9.738,P<0.001).More patients in the death group had underlying diseases(72.5%vs.41.4%,χ2=22.105,P<0.001).Patients in the death group had a significantly longer time of illness onset to hospitalization(10.0[6.5,12.0]vs.7.0[5.0,10.0]days,Z=3.216,P=0.001).On admission,the proportions of patients with symptoms of dyspnea(70.6%vs.19.0%,χ2=60.905,P<0.001)and expectoration(32.1%vs.12.1%,χ2=13.250,P<0.001)were significantly higher in the death group.The blood oxygen saturation was significantly lower in the death group(85[77,91]%vs.97[95,98]%,Z=10.625,P<0.001).The white blood cell(WBC)in death group was significantly higher on admission(7.23[4.87,11.17]vs.4.52[3.62,5.88]×109/L,Z=7.618,P<0.001).Patients in the death group exhibited significantly lower lymphocyte count(0.63[0.40,0.79]vs.1.00[0.72,1.27]×109/L,Z=8.037,P<0.001)and lymphocyte percentage(7.10[4.45,12.73]%vs.23.50[15.27,31.25]%,Z=10.315,P<0.001)on admission,and the lymphocyte percentage continued to decrease during hospitalization(7.10[4.45,12.73]%vs.2.91[1.79,6.13]%,Z=5.242,P<0.001).Alanine transaminase(22.00[15.00,34.00]vs.18.70[13.00,30.38]U/L,Z=2.592,P=0.010),aspartate transaminase(34.00[27.00,47.00]vs.22.00[17.65,31.75]U/L,Z=7.308,P<0.001),and creatinine levels(89.00[72.00,133.50]vs.65.00[54.60,78.75]μmol/L,Z=6.478,P<0.001)were significantly higher in the death group than those in the recovered group.C-reactive protein(CRP)levels were also significantly higher in the death group on admission(109.25[35.00,170.28]vs.3.22[1.04,21.80]mg/L,Z=10.206,P<0.001)and showed no significant improvement after treatment(109.25[35.00,170.28]vs.81.60[27.23,179.08]mg/L,Z=1.219,P=0.233).The patients in the death group had more complications such as acute respiratory distress syndrome(ARDS)(89.9%vs.8.6%,χ2=148.105,P<0.001),acute cardiac injury(59.6%vs.0.9%,χ2=93.222,P<0.001),acute kidney injury(18.3%vs.0%,χ2=23.257,P<0.001),shock(11.9%vs.0%,χ2=14.618,P<0.001),and disseminated intravascular coagulation(DIC)(6.4%vs.0%,χ2=7.655,P=0.006).Conclusions:Compared to the recovered group,more patients in the death group exhibited characteristics of advanced age,pre-existing comorbidities,dyspnea,oxygen saturation decrease,increased WBC count,decreased lymphocytes,and elevated CRP levels.More patients in the death group had complications such as ARDS,acute cardiac injury,acute kidney injury,shock,and DIC.Yan Deng Wei Liu Kui Liu Yuan-Yuan Fang Jin Shang Ling Zhou Ke Wang Fan Leng Shuang Wei Lei Chen Hui-Guo Liu 2020Chinese Medical Journal2020,,11:29
11Dual gRNAs guided CRISPR/Cas9 system inhibits hepatitis B virus replication显示文摘AIM: To screen and investigate the effective g RNAs against hepatitis B virus(HBV) of genotypes A-D.METHODS: A total of 15 g RNAs against HBV of genotypes A-D were designed. Eleven combinations of two above g RNAs(dual-g RNAs) covering the regulatory region of HBV were chosen. The efficiency of each g RNA and 11 dual-g RNAs on the suppression of HBV(genotypes A-D) replication was examined by the measurement of HBV surface antigen(HBs Ag) or e antigen(HBe Ag) in the culture supernatant. The destruction of HBV-expressing vector was examined in Hu H7 cells co-transfected with dual-g RNAs and HBVexpressing vector using polymerase chain reaction(PCR) and sequencing method, and the destruction of ccc DNAwas examined in Hep AD38 cells using KCl precipitation, plasmid-safe ATP-dependent DNase(PSAD) digestion, rolling circle amplification and quantitative PCR combined method. The cytotoxicity of these g RNAs was assessed by a mitochondrial tetrazolium assay.RESULTS: All of g RNAs could significantly reduce HBs Ag or HBe Ag production in the culture supernatant, which was dependent on the region in which g RNA against. All of dual g RNAs could efficiently suppress HBs Ag and/or HBe Ag production for HBV of genotypes A-D, and the efficacy of dual g RNAs in suppressing HBs Ag and/or HBe Ag production was significantly increased when compared to the single g RNA used alone. Furthermore, by PCR direct sequencing we confirmed that these dual g RNAs could specifically destroy HBV expressing template by removing the fragment between the cleavage sites of the two used g RNAs. Most importantly, g RNA-5 and g RNA-12 combination not only could efficiently suppressing HBs Ag and/or HBe Ag production, but also destroy the ccc DNA reservoirs in Hep AD38 cells.CONCLUSION: These results suggested that CRISPR/Cas9 system could efficiently destroy HBV expressing templates(genotypes A-D) without apparent cytotoxicity. It may be a potential approach for eradication of persistent HBV ccc DNA in chronic HBV infection patients.Jie Wang Zhong-Wei Xu Shuang Liu Rui-Yang Zhang Shan-Long Ding Xiao-Meng Xie Lu Long Xiang-Mei Chen Hui Zhuang Feng-Min Lu 2015World Journal of Gastroenterology2015,21,32:29
12Duck egg drop syndrome virus:an emerging Tembusu-related flavivirus in China显示文摘Duck egg drop syndrome virus(DEDSV) is a newly emerging pathogenic flavivirus isolated from ducks in China.DEDSV infection mainly results in severe egg drop syndrome in domestic poultry,which leads to huge economic losses.Thus,the discovery of ways and means to combat DEDSV is urgent.Since 2010,a remarkable amount of progress concerning DEDSV research has been achieved.Here,we review current knowledge on the epidemiology,symptomatology,and pathology of DEDSV.A detailed dissection of the viral genome and polyprotein sequences,comparative analysis of viral antigenicity and the corresponding potential immunity against the virus are also summarized.Current findings indicate that DEDSV should be a distinct species from Tembusu virus.Moreover,the adaption of DEDSV in wildlife and its high homology to pathogenic flaviviruses(e.g.,West Nile virus,Japanese encephalitis virus,and dengue virus),illustrate its reemergence and potential to become a zoonotic pathogen that should not be overlooked.Detailed insight into the antigenicity and corresponding immunity against the virus is of clear significance for the development of vaccines and antiviral drugs specific for DEDSV.LIU PeiPei LU Hao LI Shuang WU Ying George Fu GAO SU JingLiang 2013Science China(Life Sciences)2013,56,8:28
13Meta-analysis of robotic and laparoscopic surgery for treatment of rectal cancer显示文摘AIM: To conduct a meta-analysis to determine the relative merits of robotic surgery (RS) and laparoscopic surgery (LS) for rectal cancer. METHODS: A literature search was performed to identify comparative studies reporting perioperative outcomes for RS and LS for rectal cancer. Pooled odds ratios and weighted mean differences (WMDs) with 95% confidence intervals (95% CIs) were calculated using either the fixed effects model or random effects model. RESULTS: Eight studies matched the selection criteria and reported on 661 subjects, of whom 268 underwent RS and 393 underwent LS for rectal cancer. Compared the perioperative outcomes of RS with LS, reports of RS indicated favorable outcomes considering conversion(WMD: 0.25; 95% CI: 0.11-0.58; P = 0.001). Meanwhile, operative time (WMD: 27.92, 95% CI: -13.43 to 69.27; P = 0.19); blood loss (WMD: -32.35, 95% CI: -86.19 to 21.50; P = 0.24); days to passing flatus (WMD: -0.18, 95% CI: -0.96 to 0.60; P = 0.65); length of stay (WMD: -0.04; 95% CI: -2.28 to 2.20; P = 0.97); complications (WMD: 1.05; 95% CI: 0.71-1.55; P = 0.82) and pathological details, including lymph nodes harvested (WMD: 0.41, 95% CI: -0.67 to 1.50; P = 0.46), distal resection margin (WMD: -0.35, 95% CI: -1.27 to 0.58; P = 0.46), and positive circumferential resection margin (WMD: 0.54, 95% CI: 0.12-2.39; P = 0.42) were similar between RS and LS. CONCLUSION: RS for rectal cancer is superior to LS in terms of conversion. RS may be an alternative treatment for rectal cancer. Further studies are required.Shuang Lin Hong-Gang Jiang Zhi-Heng Chen Shu-Yang Zhou Xiao-Sun Liu Ji-Ren Yu 2011World Journal of Gastroenterology2011,17,47:26

15The FTO/miR-181b-3p/ARL5B signaling pathway regulates cell migration and invasion in breast cancer显示文摘Background:N6-methyladenosine(m6A)RNA modification has been demonstrated to be a significant regulatory process in the progression of various tumors,including breast cancer.Fat mass and obesity-associated(FTO)enzyme,initially known as the obesity-related protein,is the first identified m6A demethylase.However,the relationship between FTO and breast cancer remains controversial.In this study,we aimed to elucidate the role and clinical significance of FTO in breast cancer and to explore the underlying mechanism.Methods:We first investigated the expression of FTO in breast cancer cell lines and tissues by quantitative reverse transcription-PCR(qRT-PCR),Western blotting,and immunohistochemistry.Wound healing assay and Transwell assay were performed to determine the migration and invasion abilities of SKBR3 and MDAMB453 cells with either knockdown or overexpression of FTO.RNA sequencing(RNA-seq)was conducted to decipher the downstream targets of FTO.qRT-PCR,luciferase reporter assay,and Western blotting were employed to confirm the existence of the FTO/miR-181b-3p/ARL5B axis.The biological function of ADP ribosylation factor like GTPase 5B(ARL5B)in breast cancer cells was evaluated by wound healing assay and Transwell invasion assay.Results:High FTO expression was observed in human epidermal growth factor receptor 2(HER2)-positive breast cancer,predicting advanced progression(tumor size[P<0.001],nuclear grade[P=0.001],peritumoral lymphovascular invasion[P<0.001),lymph node metastasis[P=0.002],and TNM stage[P=0.001])and poor prognosis.Moreover,FTO promoted cell invasion and migration in vitro.Mechanistically,RNA-seq and further confirmation studies suggested that FTO up-regulated ARL5B by inhibiting miR-181b-3p.We further verified that ARL5B also displayed carcinogenic activity in breast cancer cells.Conclusion:Our work demonstrated the carcinogenic activity of FTO in promoting the invasion and migration of breast cancer cells via the FTO/miR-181b-3p/ARL5B signaling pathway.Yuanyuan Xu Shuang Ye Nan Zhang Shuhui Zheng Huatao Liu Kewen Zhou Ling Wang Yue Cao Peng Sun Tinghuai Wang 2020Cancer Communications2020,40,10:24

17Current status of diagnosis and treatment of bladder cancer in China-Analyses of Chinese Bladder Cancer Consortium database显示文摘Objective:To investigate current status of diagnosis and treatment of bladder cancer in China.Methods:A database was generated by Chinese Bladder Cancer Consortium(CBCC).From January 2007 to December 2012,14,260 cases from 44 CBCC centers were included.Data of diagnosis,treatment and pathology were collected.Results:The average age was 63.5 year-old and most patients were male(84.3%).The most common histologic types were urothelial carcinoma(91.4%),adenocarcinoma(1.8%),and squamous carcinoma(1.9%).According to 1973 and 2004 WHO grading system,42.0%,41.0%,and 17.0% of patients were grade 1,2,and 3,and 16.0%,48.7%,and 35.3% of patients were papillary urothelial neoplasms of low malignant potential,low,and high grade,respectively.Non-muscle invasive bladder cancer(NMIBC)and muscle invasive bladder cancer(MIBC)were 25.2% and 74.1%,respectively(0.8% not clear).Carcinoma in situ was only 2.4%.Most patients were diagnosed by white-light cystoscopy with biopsy(74.3%).Fluorescence and narrow band imaging cystoscopy had additional detection rate of 1.0% and 4.0%,respectively.Diagnostic transurethral resection(TUR)provided detection rate of 16.9%.Most NMIBCs were treated with TUR(89.2%).After initial TUR,2.6%accepted second TUR,and 45.7%,69.9%,and 58.7% accepted immediate,induced,and maintenance chemotherapy instillation,respectively.Most MIBCs were treated with radical cystectomy(RC,59.7%).Laparoscopic RCs were 35.1%,while open RC 63.4%.Extended and standard pelvic lymph node dissection were 7% and 66%,respectively.Three most common urinary diversions were orthotopic neobladder(44%),ileal conduit(31%),and ureterocutaneostomy(23%).Only 2.3% of patients accepted neo-adjuvant chemotherapy and only 18%of T3 and T4 patients accepted adjuvant chemotherapy.Conclusion:Disease characteristics are similar to international reports,while differences of diagnosis and treatment exist.This study can provide evidences for revisions of the guideline on bladder cancer in China.Kaiwen Li Tianxin Lin Wei Xue Xin Mu Enci Xu Xu Yang Fubao Chen Guangyong Li Lulin Ma Guoliang Wang Chaozhao Liang Haoqiang Shi Ming Li Mao Tang Xueyi Xue Yisong Lv Yaoliang Deng Chengyang Li Zhiwen Chen Xiaozhou Zhou Fengshuo Jin Xudong Liu Jinxin Wei Lei Shi Xin Gou Weiyang He Liqun Zhou Lin Cai Baiye Jin Guanghou Fu Xiangbo Kong Hongyan Sun Ye Tian Lang Feng Tiejun Pan Yiyi Wu Dongwen Wang Hailong Hao Benkang Shi Yaofeng Zhu Qiang Wei Ping Han Changli Wu Dawei Tian Zhangqun Ye Zheng Liu Zhiping Wang Junqiang Tian Lin Qi Minfeng Chen Wei Li Jinchun Qi Gongxian Wang Longlong Fu Zhaolin Sun Guangheng Luo Zhoujun Shen Zhaowei Zhu Jinchun Xing Zhun Wu Dong Wei Xin Chen Yanqun Na Hongfeng Guo Chunxi Wang Zhihua Lu Chuize Kong Yang Liu Jin Yang Jianyun Hu Xin Gao Jielin Li Changjun Yin Pu Li Shan Chen Zhen Du Jiongming Li Yongji Yan Xu Zhang Shuang Huang Fangjian Zhou Zhiling Zhang Yinghao Sun Shuxiong Zeng Song Cen Jiaquan Zhou Hanzhong Li Jin Wen Jian Huang 2015Asian Journal of Urology2015,2,2:21
18Additive and Over-dominant Effects Resulting from Epistatic Loci Are the Primary Genetic Basis of Heterosis in Rice显示文摘A set of 148 F9 recombinant inbred lines(RILs) was developed from the cross of an indica cultivar 93-11 and japonica cultivar DT713,showing strong F1 heterosis.Subsequently,two backcross F1(BCF1) populations were constructed by backcrossing these 148 RILs to two parents,93-11 and DT713.These three related populations(281BCF1 lines,148 RILs) were phenotyped for six yield-related traits in two locations.Significant inbreeding depression was detected in the population of RILS and a high level of heterosis was observed in the two BCF1 populations.A total of 42 main-effect quantitative trait loci(M-QTLs) and 109 epistatic effect QTL pairs(E-QTLs) were detected in the three related populations using the mixed model approach.By comparing the genetic effects of these QTLs detected in the RILs,BCF1 performance and mid-parental heterosis(HMP),we found that,in both BCF1 populations,the QTLs detected could be classified into two predominant types:additive and over-dominant loci,which indicated that the additive and over-dominant effect were more important than complete or partially dominance for M-QTLs and E-QTLs.Further,we found that the E-QTLs detected collectively explained a larger portion of the total phenotypic variation than the M-QTLs in both RILs and BCF1 populations.All of these results suggest that additive and over-dominance resulting from epistatic loci might be the primary genetic basis of heterosis in rice.Xiaojin Luo Yongcai Fu Peijiang Zhang Shuang Wu Feng Tian Jiayong Liu Zuofeng Zhu Jinshui Yang Chuanqing Sun 2009Journal of Integrative Plant Biology2009,51,4:20
19Valproic acid reduces autophagy and promotes functional recovery after spinal cord injury in rats显示文摘Secondary damage is a critical determinant of the functional outcome in patients with spinal cord injury (SCI), and involves multiple mechanisms of which the most important is the loss of nerve cells mediated by multiple factors. Autophagy can result in cell death, and plays a key role in the development of SCI. It has been recognized that valproic acid (VPA) is neuroprotective in certain experimental animal models, however, the levels of autophagic changes in the process of neuroprotection by VPA treatment following SCI are still unknown. In the present study, we determined the extent of autophagy after VPA treatment in a rat model of SCI. We found that both the mRNA and protein levels of Beclin-1 and LC3 were significantly increased at 1, 2, and 6 h after SCI and peaked at 2 h; however, Western blot showed that autophagy was markedly decreased by VPA treatment at 2 h post-injury. Besides, post-SCI treatment with VPA improved the Basso-Beattie-Bresnahan scale, increased the number of ventral horn motoneurons, and reduced myelin sheath damage compared with vehicle-treated animals at 42 days after SCI. Together, our results demonstrated the characteristics of autophagy expression following SCI, and found that VPA reduced autophagy and enhanced motor function.Hai-Hu Hao Li Wang Zhi-Jian Guo Lang Bai Rui-Ping Zhang Wei-Bing Shuang Yi-Jia Jia Jie Wang Xiao-Yu Li Qiang Liu 2013Neuroscience Bulletin2013,29,4:19
