1Darwin:a neuromorphic hardware co-processor based on Spiking Neural Networks显示文摘Broadly speaking, the goal of neuromorphic engineering is to build computer systems that mimic the brain. Spiking Neural Network(SNN) is a type of biologically-inspired neural networks that perform information processing based on discrete-time spikes, different from traditional Artificial Neural Network(ANN).Hardware implementation of SNNs is necessary for achieving high-performance and low-power. We present the Darwin Neural Processing Unit(NPU), a neuromorphic hardware co-processor based on SNN implemented with digitallogic, supporting a maximum of 2048 neurons, 20482= 4194304 synapses, and 15 possible synaptic delays.The Darwin NPU was fabricated by standard 180 nm CMOS technology with an area size of 5 × 5 mm2and70 MHz clock frequency at the worst case. It consumes 0.84 m W/MHz with 1.8 V power supply for typical applications. Two prototype applications are used to demonstrate the performance and efficiency of the hardware implementation.Juncheng SHEN De MA Zonghua GU Ming ZHANG Xiaolei ZHU Xiaoqiang XU Qi XU Yangjing SHEN Gang PAN 2016Science China(Information Sciences)2016,59,2:18

3Dredging hand Yang meridians with deep tissue massage combined with neck movement in stiff-neck syndrome:A randomized controlled trial显示文摘Objective:The objective of this study is to observe the therapeutic effects of dredging hand Yang meridian with deep tissue massage combined with neck movement on stiff-neck syndrome.Materials and Methods:This is a randomized controlled trial.The consecutive patients with the stiff-neck syndrome were randomly allocated into the intervention group and patch group(1:1)according to the random number table.The intervention group was treated with dredging hand Yang meridian with deep tissue massage combined with neck movement once a day for 3 days,while the patch group therapy was treated with a 3-patch therapy and every patch included 24-h patch and 24-h patch-free.A needle electromyogram would be exerted if the patients were at their willingness in different stages.The pain of patients was assessed by Visual Analog Scale in the two groups at every 24 h time point.Results:Finally,212 patients completed the trial,106 in each group.The curative rate in the intervention group was higher than in the patch group(99.06%vs.84.91%,χ^(2)=0.890,P<0.01).Repeated measures of the general linear model showed a significant difference in pain score within the subject-factors(factor of time F=4548.577,P<0.001;factor of time-group F=490.034,P<0.001).There was a significant difference between groups regarding pain score(F=3016.315,P<0.001).Conclusion:Dredging hand Yang meridian with deep tissue massage combined with neck movement is better than patch therapy in stiff-neck syndrome,with a shorter duration and instant effects.Xueguo SUN Zonghua QI Ying LIU Yan LI Xianli DOU Lingyun ZHANG 2022Journal of Integrative Nursing2022,4,4:0
4CFTR is a negative regulator ofγδT cell IFN-γproduction and antitumor immunity显示文摘CFTR,a chloride channel and ion channel regulator studied mostly in epithelial cells,has been reported to participate in immune regulation and likely affect the risk of cancer development.However,little is known about the effects of CFTR on the differentiation and function ofγδT cells.In this study,we observed that CFTR was functionally expressed on the cell surface ofγδT cells.Genetic deletion and pharmacological inhibition of CFTR both increased IFN-γrelease by peripheralγδT cells and potentiated the cytolytic activity of these cells against tumor cells both in vitro and in vivo.Interestingly,the molecular mechanisms underlying the regulation ofγδT cell IFN-γproduction by CFTR were either TCR dependent or related to Ca^(2+)influx.CFTR was recruited to TCR immunological synapses and attenuated Lck-P38 MAPK-c-Jun signaling.In addition,CFTR was found to modulate TCR-induced Ca^(2+)influx and membrane potential(Vm)-induced Ca^(2+)influx and subsequently regulate the calcineurin-NFATc1 signaling pathway inγδT cells.Thus,CFTR serves as a negative regulator of IFN-γproduction inγδT cells and the function of these cells in antitumor immunity.Our investigation suggests that modification of the CFTR activity ofγδT cells may be a potential immunotherapeutic strategy for cancer.Yuanyuan Duan Guangqiang Li Miaomiao Xu Xiaofei Qi Mingxia Deng Xuejia Lin Zhiwei Lei Yi Hu Zhenghu Jia Quanli Yang Guangchao Cao Zonghua Liu Qiong Wen Zhenhua Li Jie Tang Wei Kevin Zhang Pingbo Huang Limin Zheng Richard A.Flavell Jianlei Hao Zhinan Yin 2021Cellular & Molecular Immunology2021,18,8:0
