1Sodium oligomannate therapeutically remodels gut microbiota and suppresses gut bacterial amino acids-shaped neuroinflammation to inhibit Alzheimer's disease progression显示文摘Recently,increasing evidence has suggested the association between gut dysbiosis and Alzheimer's disease(AD)progression,yet the role of gut microbiota in AD pathogenesis remains obscure.Herein,we provide a potential mechanistic link between gut microbiota dysbiosis and neuroinflammation in AD progression.Using AD mouse models,we discovered that,during AD progression,the alteration of gut microbiota composition leads to the peripheral accumulation of phenylalanine and isoleucine,which stimulates the differentiation and proliferation of pro-inflammatory T helper 1(Thl)cells.The brain-infiltrated peripheral Th1 immune cells are associated with the Ml microglia aaivation,contributing to AD-associated neuroinflammation.Importantly,the elevation of phenylalanine and isoleucine concentrations and the increase of Th1 cell frequency in the blood were also observed in two small independent cohorts of patients with mild cognitive impairment(MCI)due to AD.Furthermore,GV-971,a sodium oligomannate that has demonstrated solid and consistent cognition improvement in a phase 3 clinical trial in China,suppresses gut dysbiosis and the associated phenylalanine/isoleucine accumulation,harnesses neuroinflammation and reverses the cognition impairment.Together,our findings highlight the role of gut dysbiosis-promoted neuroinflammation in AD progression and suggest a novel strategy for AD therapy by remodelling the gut microbiota.Xinyi Wang Guangqiang Sun Teng Feng Jing Zhang Xun Huang Tao Wang Zuoquan Xie Xingkun Chu Jun Yang Huan Wang Shuaishuai Chang Yanxue Gong Lingfei Ruan Guanqun Zhang Siyuan Yan Wen Lian Chen Du Dabing Yang Qingli Zhang Feifei Lin Jia Liu Haiyan Zhang Changrong Ge Shifu Xiao Jian Ding Meiyu Geng 2019Cell Research2019,29,10:192
2Analysis of in vivo patterns of caspase 3 gene expression in primary hepatocellular carcinoma and its relationship to p21^(WAF1) expression and hepatic apoptosis显示文摘AIM To detect the expression of caspase 3gene in primary human hepatocellular carcinoma(HCC)and investigate its relationship to p21WAF1gene expression and HCC apoptosis.METHODS In situ hybridization was employedto determine caspase 3 and p21WAF1expression inHCC.In situ end-labeling was used to detecthepatocytic apoptosis in HCC.RESULTS Twenty-one of 39(53.8%)cases ofHCC were found to express caspase 3transcripts,while 45.2% of HCC failed toexpress caspase 3.Non-cancerous adjacent livertissues showed more positive caspase 3(87.5%,7/8)as compared with HCC(P<0.05).The expression of caspase 3 is correlated withHCC differentiation,72.2%(13/18)ofmoderately to highly differentiated HCC showedcaspase 3 transcripts positive,while only 38.1%of poorly differentiated HCC harbored caspase 3transcripts(P<0.05).No relationship wasfound between caspase 3 expression and tumorsize or grade or metastasis,although 52.5%(5/8)of HCC with metastasis were caspase 3positive and a little higher than that with nometastasis(51.6%,P>0.05).Expression of caspase 3 alone did not affect the apoptosisindex(AI)of HCC.The AI was 7.12%o in caspase3-positive tumors(n=21),while in caspase 3-negative cases(n=18)6.59%0(P>0.05).Expression of caspase 3 clearly segregated withp21WAF1positive tumors as compared withp21WAF1-negative cases(16 of 23,69.6% versus5 of 16,31.3%)with statistical significance(P=0.017).In the cases with positive caspase 3and negative p21WAF1,the Al was found slightlyhigher,but with no statistical significance,thanthat with expression of p21WAF1and caspase 3(7.21‰ vs 6.98‰,P>0.05).CONCLUSION Loss of caspase 3 expressionmay contribute to HCC carcinogenesis,althoughthe expression of caspase 3 does not correlatewell with cell apoptosis in HCC.p21WAF1may bemerely one of the inhibitors which can reducecaspase 3 mediated cell apoptosis in HCCs.Bao Hua Sun Jun Zhang Bao JǜWang Xi Ping Zhao You Kun Wang Zhi Qun Yu Dong Liang Yang Lian Jie Hao Department of Clinical Immunology,Tongji Hospital,Tongji Medical University,Wuhan 430030,Hubei Province,China 2000World Journal of Gastroenterology2000,6,3:65
3Multiple genetic alterations and behavior of cellular biology in gastric cancer and other gastric mucosal lesions:H.pylori infection,histological types and staging显示文摘AIM To investigate the expression of multiplegenes and the behavior of cellular biology ingastric cancer(GC)and other gastric mucosallesions and their relations to Helicobacter pylori(H.pylori)infection,tumor staging andhistological subtypes.METHODS Three hundred and twenty-sevenspecimens of gastric mucosa obtained viaendoscopy or surgical resection,and ABCimmunohistochemical staining were used todetect the expression of p53,p16,Bcl-2 andCOX-2 proteins.H.pylori was determined byrapid urea test combined with pathologicalstaining or14C urea breath test.Cellular image analysis was performed in 66 patients withintestinal metaplasia(IM)and/or dysplasia(Dys).In 30 of them,both cancer and theparacancerous tissues were obtained at the timeof surgery.Histological pattern,tumor staging,lymph node metastasis,grading ofdifferentiation and other clinical data werestudied in the medical records.RESULTS p16 expression of IM or Dys wassignificantly lower in positive H.pylori chronicatrophic gastritis(CAG)than those withnegative H.pylori(CAG:54.8% vs 88.0%,IM:34.4% vs 69.6%,Dys:23.8% vs 53.6%,allP<0.05),Bcl-2 or COX-2 expression of IM orDys in positive H.pylori cases was significantlyhigher than that without H.pylori(Bcl-2:68.8%vs23.9%,90.5% vs 60.7%;COX-2:50.0% vs10.8%,61.8% vs 17.8%;all P<0.05).Themean number of most parameters of cellularimage analysis in positive H.pylori group wassignificantly higher than that in negative H.pylori group(Ellipser:53±14,40±12μm,Area1:748±572,302±202 μm2,Area2:3050±1661,1681±1990 μm2,all P<0.05;Ellipseb:79±23,58±15 μm,Ratio1:22%±5%,13%±4%,Ratio2:79%±17%,53%±20%,all P<0.01).There was significant correlation between Bcl-2and histologic pattern of gastric carcinoma,andbetween COX-2 and tumor staging or lymph nodemetastasis(Bcl-2:75.0% vs 16.7%;COX-2:76.0% vs 20.0%,79.2% vs 16.7%;allP<0.05).CONCLUSION p1l6, Bcl-2, and COX-2 but not p53 gene may play a role in the early genesis/ progression of gastric carcinoma and are associated with H. pylori infection. p53 gene is relatively late event in gastric tumorigenesis and mainly relates to its progression. There is more cellular-biological behavior of malignant tumor in gastric mucosal lesions with H. pylori infection. Aberrant Bcl-2 protein expression appears to be preferentially associated with the intestinal type cancer. COX-2 seems to be related to tumor staging and lymph node metastasis.Heng Jun Gao Lian Zhen Yu Jian Feng Bai Yan Shen Peng Gu Sun Han Lin Zhao Kun Miu Xiu Zhen Lü Xiao Yong Zhang Zhi Quan Zhao 2000World Journal of Gastroenterology2000,6,6:52

6Prediction of casing wear in extended-reach drilling显示文摘Intermediate casings in the build sections are subject to severe wear in extended-reach drilling. This paper presents a new method for predicting the depth of a wear groove on the intermediate casing. According to energy principle and dynamic accumulation of casing wear by tool joints, a model is established to calculate the wear area on the inner wall of the casing. The relationship functions between the wear groove depth and area are obtained based on the geometry relationship between the drillstring and the wear section and the assumption that the casing wear groove is crescent-shaped. The change of casing wear groove depth versus drilling footage under different-sized drillstrings is also discussed. A mechanical model is proposed for predicting casing wear location, which is based on the well trajectory and drillstring movement. The casing wear groove depth of a planned well is predicted with inversion of the casing wear factor from the drilled well and necessarily revised to improve the prediction accuracy for differences between the drilled well and the planned well. The method for predicting casing wear in extended-reach drilling is verified through actual case study. The effect of drillstring size on casing wear should be taken into account in casing wear prediction.Gao Deli Sun Lianzhong Lian Jihong 2010Petroleum Science2010,7,4:18

9Enhanced photocatalytic activity of rGO/TiO2 for the decomposition of formaldehyde under visible light irradiation显示文摘Due to the low concentration of indoor air contaminants,photocatalytic technology shows low efficiency for indoor air purification.The application of TiO_2 for photocatalytic removal of formaldehyde is limited,because TiO_2 can only absorb ultraviolet(UV) light.Immobilization of TiO_2 nanoparticles on the surface of graphene can improve the visible light photocatalytic activity and the adsorption capacity.In this study,rGO(reduced graphene oxide)/TiO_2 was synthesized through a hydrothermal method using titanium tetrabutoxide and graphene oxide as precursors,and was used for the degradation of low concentration formaldehyde in indoor air under visible light illumination.Characterization of the crystalline structure and morphology of rGO/TiO_2 revealed that most GO was reduced to rGO during the hydrothermal treatment,and anatase TiO_2 nanoparticles(with particle size of 15–30 nm) were dispersed well on the surface of the rGO sheets.rGO/TiO_2 exhibited excellent photocatalytic activity for degradation of formaldehyde in indoor air and this can be attributed to the role of rGO,which can act as the electron sink and transporter for separating photo-generated electron–hole pairs through interfacial charge transfer.Furthermore,rGO could adsorb formaldehyde molecules from air to produce a high concentration of formaldehyde on the surface of rGO/TiO_2.Under visible light irradiation for 240 min,the concentration of formaldehyde could be reduced to 58.5 ppbV.rGO/TiO_2 showed excellent moisture-resistance behavior,and after five cycles,r GO/TiO_2 maintained high photocatalytic activity for the removal of formaldehyde(84.6%).This work suggests that the synthesized rGO/TiO_2 is a promising photocatalyst for indoor formaldehyde removal.Lian Yu Long Wang Xibo Sun Daiqi Ye 2018Journal of Environmental Sciences2018,30,11:13
10Chinese Medicine Sequential Therapy Improves Pregnancy Outcomes after Surgery for Endometriosis-Associated Infertility: A Multicenter Randomized Double-blind Placebo Parallel Controlled Clinical Trial显示文摘Objective:To evaluate the efficacy and safety of Chinese medicine(CM)improving pregnancy outcomes after surgery for endometriosis-associated infertility.Methods:A multicenter,randomized,doubleblind placebo parallel controlled clinical trial was designed.A total of 202 patients who had laparoscopy for endometriosis-associated infertility with qi stagnation and blood stasis syndrome were included and randomly divided into the CM treatment group and placebo control group at a ratio of 1:1 using a central block randomization from May 2014 to September 2017,101 patients in each group.The two groups received continuous intervention at 1–5 days after surgery,for 6 menstrual cycles.Before ovulation,the CM group was treated Huoxue Xiaoyi Granule(活血消异颗粒);after ovulation,Bushen Zhuyun Granule(补肾助孕颗粒)was involved.The control group was treated with placebo.Transvaginal ultrasonography was performed every menstrual cycle during the treatment,and female hormone levels in the follicular and luteal phases were measured during the 1 st,3 rd and 6 th menstrual cycles.The analysis was continued until pregnancy.The primary outcomes were clinical pregnancy rate and pregnancy outcome,and the secondary outcomes were follicular development and endometrial receptivity.Safety evaluations were performed before and after treatment.Results:(1)Clinical pregnancy and live birth rates:the clinical pregnancy and live birth rates of the CM group were significantly higher than those of the placebo group[44.6%(45/101)vs.29.7%(30/101),34.7%(35/101)vs.20.8%(21/101),both P<0.05].(2)Follicle development:the incidence of dominant follicles,rate of cumulative cycle ovulation,and rate of cumulative cycle mature follicle ovulation were significantly higher in the CM group than those in the placebo group[93.8%(350/373)vs.89.5%(341/381),80.4%(275/342)vs.69.1%(253/366),65.8%(181/275)vs 56.1%(142/253),P<0.05 or P<0.01]).The incidence of cumulative cycle luteinized unruptured follicle syndrome was significantly lower in the CM group than in the placebo group[11.7%(40/342)vs.17.8%(65/366),P<0.05).(3)Endometrial receptivity:after treatment,both endometrial types and endometrial blood flow types in the CM group were mainly types A and B,while those in the placebo group were mainly types B and C,with a significant difference between the two groups(both P<0.05).(4)Adverse events:the incidence of adverse events between the two groups was not significantly different(P>0.05).Conclusion:Strategies for activating blood circulation-regulating Gan(Liver)-tonifying Shen(Kidney)sequential therapy can effectively improve the clinical pregnancy rate and live birth rate of endometriosis-associated infertility with qi stagnation and blood stasis after laparoscopy,improve follicular development,promote ovulation,improve endometrial receptivity,while being a safe treatment option.(Trial registration No.NCT02676713).ZHAO Rui-hua LIU Yong LU Dan WU Ying WANG Xiao-yun LI Wei-li ZENG Cheng MENG Qing-wei LIAN Feng-mei ZHOU Jun SHI Yun SUN Wei-wei HAN Qian TANG Yi SHI Guang 2020Chinese Journal of Integrative Medicine2020,26,2:13
11Extracellular Signal-Regulated Kinase in Nucleus Accumbens Mediates Propofol Self-Administration in Rats显示文摘Clinical and animal studies have indicated that propofol has potential for abuse,but the specific neurobiological mechanism underlying propofol reward is not fully understood.The purpose of this study was to investigate the role of extracellular signal-regulated kinase(ERK) signal transduction pathways in the nucleus accumbens(NAc) in propofol self-administration.We tested the expression of p-ERK in the NAc following the maintenance of propofol self-administration in rats.We also assessed the effect of administration of SCH23390,an antagonist of the D1 dopamine receptor,on the expression of p-ERK in the NAc in propofol self-administering rats,and examined the effects of intra-NAc injection of U0126,an MEK inhibitor,on propofol reinforcement in rats.The results showed that the expression of p-ERK in the NAc increased significantly in rats maintained on propofol,and pre-treatment with SCH23390 inhibited the propofol selfadministration and diminished the expression of p-ERK in the NAc.Moreover,intra-NAc injection of U0126(4 μg/side) attenuated the propofol self-administration.The data suggest that ERK signal transduction pathways coupled with D1 dopamine receptors in the NAc may be involved in the maintenance of propofol self-administration and its rewarding effects.Benfu Wang Xiaowei Yang Anna Sun Lanman Xu Sicong Wang Wenxuan Lin Miaojun Lai Huaqiang Zhu Wenhua Zhou Qingquan Lian 2016Neuroscience Bulletin2016,32,6:12

13Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12

15Effects of Electroacupuncture on Expression of PI3K/Akt/Foxo3a in Granulosa Cells from Women with Shen(Kidney) Deficiency Syndrome Undergoing in vitro Fertilization-Embryo Transfer显示文摘Objective: To observe the effects of electroacupuncture(EA) on reproductive outcomes in women with Shen(Kidndy) deficiency syndrome after in vitro fertilization-embryo transfer(IVF-ET),and explore the underlying molecular mechanism.Methods: Sixty-six infertile patients with Shen de?ciency syndrome undergoing IVF-ET were divided into EA or control groups according to a random table,33 cases in each group.Before undergoing IVF,patients in the EA and control groups received EA therapy and placebo needle puncture,respectively,for 3 menstrual cycles.Shen de?ciency syndrome scores were assessed.Other outcome measures included the number of retrieved oocytes and fertilization,high-quality embryo and clinical pregnancy rates.Follicular ?uid was collected on the day of oocyte retrieval,and granulosa cell expression of phosphatidylinositide3-kinases(PI3 K),serine-threonine kinase(Akt) and forkhead box O3(Foxo3 a) m RNA were measured by reverse transcribed and quantitative real-time polymerase chain reaction.Results: Syndrome scores for pre-versus post-treatments decreased significantly(16.53±1.75 to 8.67±1.61) in the EA group(P<0.05),but showed no signi?cant change in the control group(17.18±1.58 to 14.74±1.58).A signi?cant difference in score change was found between the EA and control groups(P<0.05).High-quality embryo and clinical pregnancy rates were both increased in the EA group compared with the control group [69.15%(195/282) vs.60.27%(176/292) and 66.67%(22/33) vs.42.42%(14/33),respectively,P<0.05].The fertilization rate was equivalent in EA and control groups.No difference was found in the number of retrieved oocytes between the two groups.Granulosa cell expression levels of PI3 K and Akt m RNA were signi?cantly increased in the EA group compared with the control group,while the expression of Foxo3 a was reduced(all P<0.05).Conclusions: For infertile patients with Shen de?ciency syndrome undergoing IVF,EA for tonifying Shen as an adjunct treatment may alleviate clinical symptoms and improve the high-quality embryo rate.The EA-induced mechanism may involve regulation of PI3 K/Akt/Foxo3 a expression in granulosa cells to improve the developmental microenvironment of oocytes and inhibit granulosa cell apoptosis,possibly contributing to the improved clinical pregnancy rate(Registration No.Chi CTR 1800016217).WU Hai-cui ZHANG Jian-wei SUN Zhen-gao XIANG Shan QIAO Yan LIAN Fang 2019Chinese Journal of Integrative Medicine2019,25,4:10
16Application of micro-seismic monitoring technology in mining engineering显示文摘Micro-seismic phenomena, occurring when rock masses are subjected to forces and failures, allow the determination of their unstable states and failure zones by analyzing micro-seismic signals. We first present the principles of micro-seismic monitoring and location, as well as an underground explosion-proof micro-seismic monitoring system. Given a practical engineering application, we describe the application of micro-seismic monitoring technology in determining the height of a 'two-zone' overburden, i.e., a caving zone and a fracture zone, the width of a coal-pillar section and the depth of failure of a floor.

17CD147-spike protein is a novel route for SARS-CoV-2 infection to host cells显示文摘In face of the everlasting battle toward COVID-19 and the rapid evolution of SARS-CoV-2,no specific and effective drugs for treating this disease have been reported until today.Angiotensin-converting enzyme 2(ACE2),a receptor of SARS-CoV-2,mediates the virus infection by binding to spike protein.Although ACE2 is expressed in the lung,kidney,and intestine,its expressing levels are rather low,especially in the lung.Considering the great infectivity of COVID-19,we speculate that SARS-CoV-2 may depend on other routes to facilitate its infection.Here,we first discover an interaction between host cell receptor CD147 and SARS-CoV-2 spike protein.The loss of CD147 or blocking CD147 in Vero E6 and BEAS-2B cell lines by anti-CD147 antibody,Meplazumab,inhibits SARSCoV-2 amplification.Expression of human CD147 allows virus entry into non-susceptible BHK-21 cells,which can be neutralized by CD147 extracellular fragment.Viral loads are detectable in the lungs of human CD147(hCD147)mice infected with SARS-CoV-2,but not in those of virus-infected wild type mice.Interestingly,virions are observed in lymphocytes of lung tissue from a COVID-19 patient.Human T cells with a property of ACE2 natural deficiency can be infected with SARS-CoV-2 pseudovirus in a dosedependent manner,which is specifically inhibited by Meplazumab.Furthermore,CD147 mediates virus entering host cells by endocytosis.Together,our study reveals a novel virus entry route,CD147-spike protein,which provides an important target for developing specific and effective drug against COVID-19.Ke Wang Wei Chen Zheng Zhang Yongqiang Deng Jian-Qi Lian Peng Du Ding Wei Yang Zhang Xiu-Xuan Sun Li Gong Xu Yang Lei He Lei Zhang Zhiwei Yang Jie-Jie Geng Ruo Chen Hai Zhang Bin Wang Yu-Meng Zhu Gang Nan Jian-Li Jiang Ling Li Jiao Wu Peng Lin Wan Huang Liangzhi Xie Zhao-Hui Zheng Kui Zhang Jin-Lin Miao Hong-Yong Cui Min Huang Jun Zhang Ling Fu Xiang-Min Yang Zhongpeng Zhao Shihui Sun Hongjing Gu Zhe Wang Chun-Fu Wang Yacheng Lu Ying-Ying Liu Qing-Yi Wang Huijie Bian Ping Zhu Zhi-Nan Chen 2020Signal Transduction and Targeted Therapy2020,5,1:9
18Construction and anti-tumor effects of recombinant fowlpox virus expressing Newcastle disease virus hemagglutinin-neuramidinase gene显示文摘Hemagglutinin-neuramidinase (HN ) ,纽卡斯尔疾病导出病毒的蛋白质,不是仅仅调停受体识别而且拥有 neuraminidase (NA ) 活动,劈开那些受体的一个部件的能力, N-acetylneuraminic 酸(NAcneu, sialic ) 。包括人,在哺乳动物的种类的这蛋白质有有趣的反肿瘤以及有免疫力的刺激性质,这被知道。在癌症基因治疗探索 HN 基因的使用,我们构造了表示 HN 蛋白质(vFV-HN ) 的一个 recombinant 家禽痘病毒并且在 vivo 并且在 vitro 把 recombinant 病毒的 theanti 肿瘤活动与野类型的家禽痘病毒(FPV ) 的作比较。这里,我们发现尽管 B16 房间对野类型的家禽痘病毒的基础细胞毒素的效果有点抵抗,有 vFV-HN 的感染引起了显著细胞毒素的效果并且,与 vFV-HN 使免疫的忍受肿瘤的老鼠的幸存显著地与独自与 FPV 使免疫的老鼠的幸存相比被增加。而且,有 vFV-HNelicited 的老鼠的免疫 B16 肿瘤特定的细胞毒素的 T 淋巴细胞(CTL ) 回答和在 vivo 的 bothCD4+ 和 CD8+ T 房间人口的同种细胞的扩大。另外,从老鼠的淋巴节点的 T 房间种牛痘, Th1 cytokine IL-2 和 IFN-v 高级的 vFV-HN 藏匿了,显示肿瘤房间的回归与 Th1 类型主导的有免疫力的回答有关。这些结果证明有 vFV-HN 的种痘可以是为癌症基因治疗的潜在的策略。LI Xiao JIN Ningyi LIAN Hai GUAN Goufang SUN Lili LI Xue mei ZHENG Hongling 2006Chinese Science Bulletin2006,51,22:9
19Local Gabor Dominant Direction Pattern for Face Recognition显示文摘We propose a novel face image representation – Local gabor dominant direction pattern(LGDDP)for face recognition. The face image is convolved with the Gabor filters, resulting in multiple response images of different orientations and scales. The response images' each pixel is encoded by the LGDDP descriptor from the pixel's dominant neighboring one or two pixels. The image formed by the LGDDP descriptor is partitioned into multiple regions and the histogram is extracted from each region. All the histograms are concatenated into the spatial histogram.The nearest neighbor classifier and the weighted intersection histogram similarity measure are used for face image classification. The advantage of the proposed LGDDP method lies in the high recognition rate performance and the low computational complexity. Extensive experiments are performed on FERET face image database and the experimental results verify the LGDDP's effectiveness by comparing LGDDP with other well-known published face recognition methods.LIU Jun JING Xiaojun SUN Songlin LIAN Zifeng 2015Chinese Journal of Electronics2015,24,2:8
