1PCT:Point cloud transformer显示文摘The irregular domain and lack of ordering make it challenging to design deep neural networks for point cloud processing.This paper presents a novel framework named Point Cloud Transformer(PCT)for point cloud learning.PCT is based on Transformer,which achieves huge success in natural language processing and displays great potential in image processing.It is inherently permutation invariant for processing a sequence of points,making it well-suited for point cloud learning.To better capture local context within the point cloud,we enhance input embedding with the support of farthest point sampling and nearest neighbor search.Extensive experiments demonstrate that the PCT achieves the state-of-the-art performance on shape classification,part segmentation,semantic segmentation,and normal estimation tasks.Meng-Hao Guo Jun-Xiong Cai Zheng-Ning Liu Tai-Jiang Mu Ralph R.Martin Shi-Min Hu 2021Computational Visual Media2021,7,2:55

3Predictive value of the Chinese group on the study of severe hepatitis B-acute-on-chronic liver failure score in the short-term prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure显示文摘Background:As a large,prospective,multicenter study-based prognostic score for hepatitis B virus-related acute-on-chronic liver failure(HBV-ACLF),the Chinese group on the study of severe hepatitis B-acute-on-chronic liver failure score(COSSH-ACLFs),has been approved by some foreign scholars;however,its predictive value needs to be verified.This study investigated the predictive value of COSSH-ACLFs for short-term prognosis in Chinese patients with HBV-ACLF.Methods:This retrospective cohort study included 751 patients with HBV-ACLF admitted to the Fifth Medical Center of Chinese PLA General Hospital between January 2011 and December 2014.Spearman method was used to assess the correlation of COSSHACLFs with classical scores.Different COX multivariate regression models were used to confirm the relationship between COSSHACLFs and short-term prognosis in patients with HBV-ACLF,and stratified analysis was used to further verify the stability of this relationship.We compared the predictive powers of COSSH-ACLFs and other classical scores using area under the receiver operating characteristic curve(AUROC)and Z-test.Results:A total of 975 patients with HBV-ACLF were screened,and 751 were analyzed(623 male and 128 female).COSSH-ACLFs was the highest in patients with end-stage ACLF,followed by those with middle-and early-stage ACLF(H=211.8,P<0.001).In the fully adjusted model,COX multivariate regression analysis revealed that COSSH-ACLFs(as a continuous variable)was independently and positively correlated with mortality risk in patients with HBV-ACLF at 28 days(hazard ratio[HR]:1.37[1.22,1.53],P<0.001)and 90 days(HR:1.43[1.29,1.58],P<0.001).The same trend could be observed in the crude model and minimally adjusted model.The AUROCs of COSSH-ACLFs for 28-day and 90-day prognoses in patients with HBV-ACLF were 0.807 and 0.792,respectively,indicating a stronger predictive accuracy than those of classic models.Conclusions:COSSH-ACLFs,with a superior predictive accuracy compared with other classical scores,can strongly predict shortterm prognosis in Chinese patients with HBV-ACLF.Jing-Jing Tong Wei Zhao Xiu-Ying Mu Xiang Xu Hai-Bin Su Xiao-Yan Liu Jing Chen Xing-Ran Zhai Yu Wang Jin-Hua Hu 2019Chinese Medical Journal2019,,13:27
4Attention mechanisms in computer vision:A survey显示文摘Humans can naturally and effectively find salient regions in complex scenes.Motivated by this observation,attention mechanisms were introduced into computer vision with the aim of imitating this aspect of the human visual system.Such an attention mechanism can be regarded as a dynamic weight adjustment process based on features of the input image.Attention mechanisms have achieved great success in many visual tasks,including image classification,object detection,semantic segmentation,video understanding,image generation,3D vision,multimodal tasks,and self-supervised learning.In this survey,we provide a comprehensive review of various attention mechanisms in computer vision and categorize them according to approach,such as channel attention,spatial attention,temporal attention,and branch attention;a related repository http://gffzz188fe103f8f1460asfxbwfok0uk6p6kwx.ffgz.tsg.suse.edu.cn/MenghaoG uo/Awesome-Vision-Attentions is dedicated to collecting related work.We also suggest future directions for attention mechanism research.Meng-Hao Guo Tian-Xing Xu Jiang-Jiang Liu Zheng-Ning Liu Peng-Tao Jiang Tai-Jiang Mu Song-Hai Zhang Ralph R.Martin Ming-Ming Cheng Shi-Min Hu 2022Computational Visual Media2022,8,3:27

8Determination of fluoroquinolones, sulfonamides, and tetracyclines multiresidues simultaneously in porcine tissue by MSPD and HPLC-DAD显示文摘An efficient method is provided to detect simultaneously some important veterinary drugs from different classes in highly complex animal tissue matrix. This method using matrix solid-phase dispersion (MSPD) and high performance liquid chromatography (HPLC) with diode array detection (DAD) is developed to effectively determine two fiuoroquinolones (enoxacin and lomefioxacin), two sulfonamides (sulfanilamide and sulfamethoxazole) and one tetracycline (tetracycline) simultaneously in porcine tissues. In the process, MSPD methodology was used to treat samples, washed by n-hexane to remove lipid, eluted the analytes with acetonitrile-dichloromethane (1:1, v/v). Solvent acetonitrile and solvent acetic acid (0.1%) were combined in a gradient. HPLC-DAD analysis of the tissue samples was performed within 15 min at a fiow rate of 1.0 mL/min. The results showed that a recovery at 0.1, 0.5 and 1.0 mg/g fortification levels ranged from 80.6% to 99.2% with satisfactory relative standard deviations (RSDs) (below 6.1%, nfi3) and the limits of quantitation (LOQ) ranged from 7 mg/kg to 34 mg/kg in porcine tissues. Utilization of the method in successfully simultaneous analysis of porcine tissue incurred with veterinary drug multiresidues is described.Hu Yu, Hui Mu, Ying-Mei Hu Chemistry Department of Science School, Xi’an Jiaotong University, Xi’an 710049, China 2012Journal of Pharmaceutical Analysis2012,2,1:15
9Bone morphogenetic protein-7 represses hepatic stellate cell activation and liver fibrosis via regulation of TGF-β/Smad signaling pathway显示文摘BACKGROUND Liver fibrosis is a refractory disease whose persistence can eventually induce cirrhosis or even liver cancer.Early liver fibrosis is reversible by intervention.As a member of the transforming growth factor-beta(TGF-β)superfamily,bone morphogenetic protein 7(BMP7)has anti-liver fibrosis functions.However,little is known about BMP7 expression changes and its potential regulatory mechanism as well as the relationship between BMP7 and TGF-βduring liver fibrosis.In addition,the mechanism underlying the anti-liver fibrosis function of BMP7 needs to be further explored.AIM To investigate changes in the dynamic expression of BMP7 during liver fibrosis,interactions between BMP7 and TGF-β1,and possible mechanisms underlying the anti-liver fibrosis function of BMP7.METHODS Changes in BMP7 expression during liver fibrosis and the interaction between BMP7 and TGF-β1 in mice were observed.Exogenous BMP7 was used to treat mouse primary hepatic stellate cells(HSCs)to observe its effect on activation,migration,and proliferation of HSCs and explore the possible mechanism underlying the anti-liver fibrosis function of BMP7.Mice with liver fibrosis received exogenous BMP7 intervention to observe improvement of liver fibrosis by using Masson’s trichrome staining and detecting the expression of the HSC activation indicator alpha-smooth muscle actin(α-SMA)and the collagen formation associated protein type I collagen(Col I).Changes in the dynamic expression of BMP7 during liver fibrosis in the human body were further observed.RESULTS In the process of liver fibrosis induced by carbon tetrachloride(CCl4)in mice,BMP7 protein expression first increased,followed by a decrease;there was a similar trend in the human body.This process was accompanied by a sustained increase in TGF-β1 protein expression.In vitro experiment results showed that TGF-β1 inhibited BMP7 expression in a time-and dose-dependent manner.In contrast,high doses of exogenous BMP7 inhibited TGF-β1-induced activation,migration,and proliferation of HSCs;this inhibitory effect was associated with upregulation of pSmad1/5/8 and downregulation of phosphorylation of Smad3 and p38 by BMP7.In vivo experiment results showed that exogenous BMP7 improved liver fibrosis in mice.CONCLUSION During liver fibrosis,BMP7 protein expression first increases and then decreases.This changing trend is associated with inhibition of BMP7 expression by sustained upregulation of TGF-β1 in a time-and dose-dependent manner.Exogenous BMP7 could selectively regulate TGF-β/Smad pathway-associated factors to inhibit activation,migration,and proliferation of HSCs and exert antiliver fibrosis functions.Exogenous BMP7 has the potential to be used as an antiliver fibrosis drug.Gao-Liang Zou Shi Zuo Shuang Lu Rui-Han Hu Yin-Ying Lu Jing Yang Kai-Sheng Deng Ye-Ting Wu Mao Mu Juan-Juan Zhu Jing-Zhang Zeng Bao-Fang Zhang Xian Wu Xue-Ke Zhao Hai-Yang Li 2019World Journal of Gastroenterology2019,25,30:15

11Hepatitis B surface antigen clearance in inactive hepatitis B surface antigen carriers treated with peginterferon alfa-2a显示文摘AIM: To examine the association between interferon(IFN) therapy and loss of hepatitis B surface antigen(HBs Ag) in inactive HBs Ag carriers. METHODS: This was a retrospective cohort study in inactive HBs Ag carriers, who were treatment-naive, with a serum HBs Ag level < 100 IU/m L and an undetectable hepatitis B virus(HBV) DNA level(< 100 IU/m L). All the 20 treated patients received subcutaneous PEG-IFN alfa-2a 180 μg/wk for 72 wk and were then followed for 24 wk. There were 40 untreated controls matched with 96 wk of observation. Serum HBs Ag, HBV DNA, and alanine aminotransferases were monitored every 3 mo in the treatment group and every 3-6 mo in the control group. RESULTS: Thirteen(65.0%) of 20 treated patients achieved HBs Ag loss, 12 of whom achieved HBs Ag seroconversion. Mean HBs Ag level in treated patients decreased to 6.69 ± 13.04 IU/m L after 24 wk of treatment from a baseline level of 26.22 ± 33.00 IU/m L. Serum HBV DNA level remained undetectable(< 100 IU/m L) in all treated patients during the study. HBs Ag level of the control group decreased from 25.72 ± 25.58 IU/m L at baseline to 17.11 ± 21.62 IU/m L at week 96(P = 0.108). In the control group, no patient experienced HBs Ag loss/seroconversion, and two(5.0%) developed HBV reactivation.CONCLUSION: IFN treatment results in HBs Ag loss and seroconversion in a considerable proportion of inactive HBs Ag carriers with low HBs Ag concentrations.Ming-Hui Li Yao Xie Lu Zhang Yao Lu Ge Shen Shu-Ling Wu Min Chang Cai-Qin Mu Lei-Ping Hu Wen-Hao Hua Shu-Jing Song Shu-Feng Zhang Jun Cheng Dao-Zhen Xu 2016World Journal of Hepatology2016,8,15:15
12Sequential use of transarterial chemoembolization and percutaneous cryosurgery for hepatocellular carcinoma显示文摘AIM: To evaluate the efficacy of sequential use of transarterial chemoembolization (TACE) and percutaneous cryosurgery for unresectable hepatocellular carcinoma (HCC). METHODS: Four hundred and twenty patients were enrolled in this study. The patients, who were considered to have unresectable tumors due to their location or size or comorbidity, were divided into sequential TACE-cryosurgery (sequential) group (n = 290) and cryosurgery alone (cryoalone) group (n = 130). Patients in the sequential group tended to have larger tumors and a greater number of tumors than those in the cryo-alone group. Tumors larger than 10 cm in diameter were only seen in the sequential group. TACE was performed with the routine technique and percutaneous cryosurgery was conducted under the guidance of ultrasound 2-4 wk after TACE. RESULTS: During a mean follow-up period of 42 ± 17 mo (range, 24-70 mo), the local recurrence rateat the ablated area was 17% for all patients, 11% and 23% for patients in sequential group and cryoalone groups, respectively (P = 0.001). The overall 1-, 2-, 3-, 4and 5-year survival rate was 72%, 57%, 47%, 39% and 31%, respectively. The 1and 2-year survival rates (71% and 61%) in sequential group were similar to those (73% and 54%) in cryo-alone group (P = 0.69 and 0.147), while the 4and 5-year survival rates were 49% and 39% in sequential group, higher than those (29% and 23%) in cryo-alone group (P = 0.001). Eighteen patients with large HCC (> 5 cm in diameter) survived for more than 5 years after sequential TACE while no patient with large HCC (> 5 cm in diameter) survived more than 5 years after cryosurgery. The overall complication rate was 24%, and the complication rates were 21% and 26% for the sequential and cryo-alone groups, respectively (P = 0.06). The incidence of hepatic bleeding was higher in cryo-alone group than in sequential group (P = 0.02). Liver crack only occurred in two patients of the cryoalone group. CONCLUSION: Pre-cryosurgical TACE can increase the cryoablation efficacy and decrease its adverse effects, especially bleeding. Sequential TACE and cryosurgery may be the better procedure for unresectable HCC, especially for large HCC.Ke-Cheng Xu Li-Zhi Niu Qiang Zhou Yi-Ze Hu De-Hong Guo Zheng-Ping Liu Bing Lan Feng Mu Ying-Fei Li Jian-Sheng Zuo 2009World Journal of Gastroenterology2009,15,29:13

14Pediatric reference intervals in China(PRINCE):design and rationale for a large,multicenter collaborative cross-sectional study显示文摘There is a lack of accurate pediatric reference intervals(RIs) in China, with most commonly used RIs established without consideration of the effect of age and gender. The Pediatric Reference Intervals in China(PRINCE) project aims to establish and verify pediatric RIs for 31 common laboratory measurands.The project will be a large, multicenter cross-sectional study:14,490 healthy children and adolescents aged up to 19 years will be surveyed by 10 children's hospitals and one pediatric department of a university hospital. To evaluate the feasibility and efficiency of the study methods, 602 children were surveyed in the pilot phase of the PRINCE study in April 2017: it found that some measurands were distinctly age dependent and that there were differences between values for males and females. The results of the pilot study affirmed the necessity of the PRINCE project for Chinese pediatrics. The pilot also indicated potential difficulties in the full survey, e.g., difficulties in recruiting children aged under 3 years and insufficient collection of blood samples from infants. The operation of the PRINCE project has been modified based on the findings in the pilot study toward improving the validity of the PRINCE project and promoting its openness and transparency.Xin Ni Wenqi Song Xiaoxia Peng Ying Shen Yaguang Peng Qiliang Li Yan Wang Lixin Hu Yanying Cai Hong Shang Min Zhao Hong Jiang Yaoguo Huang Runqing Mu Wenxiang Chen Mingting Peng Chuanbao Zhang Jie Zeng Chenbin Li Hongling Yang Yongmei Jiang Jin Xu Guixia Li Hongbing Chen Yun Xiang Sancheng Cao Zhenxin Guo Dapeng Chen 2018Science Bulletin2018,63,24:12
15Treatment of portal vein tumor thrombus using ^(125)Iodine seed implantation brachytherapy显示文摘We reported two cases of liver metastasis with portal vein tumor thrombus that developed after liver transplantation for hepato cellular carcinoma (HCC). Both the patients were women aged 43 and 55 years, who had liver metastasis and portal vein tumor thrombus formation after liver transplantations for HCC. For the treatment of portal vein tumor thrombus, 125I seeds were implanted into the hepatic tissue under the guidance of preoperative computed tomography (CT) images with a total radiation dose of 130 Gy. Enhanced spiral CT scan was performed for evaluation of the liver at 12 and 16 wk after treatment. Thereafter, upper abdominal CT examination was performed every 2-3 mo. No severe complications associated with the 125I seeds were seen in these two patients. The upper abdominal CT images (obtained after 3 and 4 mo of treatment) showed that the thrombosis reactions were complete reaction and restoration of the patency of the partially obstructed portal vein with partial obstruction. In the case with complete obstruction of the portal vein, the thrombosis was resolved completely, but blood flow could not be restored. After this treatment, one of the patients is stillalive, while the other died within 6 mo after the treatment due to lung metastasis complicated with lung infection, leading to respiratory failure.Lin Zhang Wei Mu Cun-Fang Hu Xue-Quan Huang 2010World Journal of Gastroenterology2010,16,38:11

19Expression of SoxC Transcription Factors during Zebrafish Retinal and Optic Nerve Regeneration显示文摘The SoxC transcription factors(Sox4,Sox11,and Sox12) play important roles in the development of the vertebrate eye and retina. However,their expression and function during retinal and optic nerve regeneration remain elusive. In this study,we investigated the expression and possible functions of the SoxC genes after retinal and optic nerve injury in adult zebrafish. We found that among the five SoxC members,Sox11b was strongly induced in BrdU-positive cells in the inner nuclear layer(INL) after retinal injury,and morpholino-mediated Sox11b-knockdown significantly reduced the number of proliferating cells in the INL at 4 days post-injury. After optic nerve lesion,both Sox11a and Sox11b were strongly expressed in retinal ganglion cells(RGCs),and knockdown of both Sox11a and Sox11b inhibited RGC axon regrowth in retinal explants. Our study thus uncovered a novel expression pattern of SoxC family genes after retinal and optic nerve injury,and suggests that they have important functions during retinal and optic nerve regeneration.Zhaoxia Mu Shuqiang Zhang Chunjiao He Haitao Hou Dong Liu Nan Hu Hui Xu 2017Neuroscience Bulletin2017,33,1:9
20F-structure model of overlying strata for dynamic disaster prevention in coal mine显示文摘The rupture and movement scope of overlying strata upon the longwall mining face increased sharply as the exploitation scale and degree growing recently,and the spatial structure formed by fractured strata became much more complex.The overlying strata above the working face and adjacent gobs would affect each other and move cooperatively because small pillar can hardly separate the connection of overlying strata between two workfaces,which leads to mining seismicity in the gob and induces rockburst disaster that named spatial structure instability rockburst in this paper.Based on the key stratum theory,the F-structure model was established to describe the overlying strata characteristic and rockburst mechanism of workface with one side of gob and the other side un-mined solid coal seam.The results show that F-structure in the gob will re-active and loss stability under the influence of neighboring mining,and fracture and shear slipping in the process of instability is the mechanism of the seismicity in the gob.The F-structure was divided into two categories that short-arm F and long-arm F structure based on the state of strata above the gob.We studied the underground pressure rules of different F-structure and instability mechanism,thus provide the guide for prevention and control of the F-structure spatial instability rockburst.The micro-seismic system is used for on-site monitoring and researching the distribution rules of seismic events,the results confrmed the existence and correct of F-spatial structure.At last specialized methods for prevention seismicity and rockburst induced by F-structure instability are proposed and applied in Huating Coal Mine.Mu Zonglong Dou Linming He Hu Fan Jun 2013International Journal of Mining Science and Technology2013,23,4:8
