| 3 | Comparison between different reconstruction routes in esophageal squamous cell carcinoma显示文摘AIM:To compare postoperative complications and prognosis of esophageal squamous cell carcinoma patients treated with different routes of reconstruction. METHODS:After obtaining approval from the Medical Ethics Committee of the Sun Yat-Sen University Cancer Center, we retrospectively reviewed data from 306 consecutive patients with histologically diagnosed esophageal squamous cell carcinoma who were treated between 2001 and 2011. All patients underwent radical McKeown-type esophagectomy with at least two-field lymphadenectomy. Regular follow-up was performed in our outpatient department. Postoperative complica-tions and long-term survival were analyzed by treatment modality, baseline patient characteristics, and operative procedure. Data from patients treated via the retrosternal and posterior mediastinal routes were compared. RESULTS:The posterior mediastinal and retrosternal reconstruction routes were employed in 120 and 186 patients, respectively. Pulmonary complications were the most common complications experienced during the postoperative period (46.1% of all patients; 141/306). Compared to the retrosternal route, the posterior mediastinal reconstruction route was associated with a lower incidence of anastomotic stricture (15.8% vs 27.4%, P = 0.018) and less surgical bleeding (242.8 ± 114.2 mL vs 308.2 ± 168.4 mL, P < 0.001). The median survival time was 26.8 mo (range:1.6-116.1 mo). Upon uni/multivariate analysis, a lower preoperative albumin level (P = 0.009) and a more advanced pathological stage (pT; P = 0.006; pN; P < 0.001) were identified as independent factors predicting poor prognosis. The reconstruction route did not influence prognosis (P = 0.477). CONCLUSION:The posterior mediastinal route of reconstruction reduces incidence of postoperative complications but does not affect survival. This route is recommended for resectable esophageal squamous cell carcinoma. | Yu-Zhen Zheng Shu-Qin Dai Wei Li Xun Cao Xin Wang Jian-Hua Fu Peng Lin Lan-Jun Zhang Bin Lu Jun-Ye Wang | 2012 | World Journal of Gastroenterology2012,18,39: | 10 |

| 5 | R-CHOP regimen can significantly decrease the risk of disease relapse and progression in patients with non-germinal centerB-cell subtype diffuse large B-cell lymphoma显示文摘To further explore the role of rituximab when added to the CHOP-like regimen in the treatment of immunohistochemically defined non-germinal center B-cell subtype (non-GCB) diffuse large B-celllymphoma (DLBCL), 159 newly diagnosed DLBCL patients were studied retrospectively based on the immunohistochemical evaluation of CD10, Bcl-6, MUM-1, and Bcl-2. Altogether, 110 patients underwent the CHOP-like regimen, and rituximab was added for the other 49 patients. Cox regression analysis showed that compared with the CHOP-like regimen, the rituximab-based regimen (R-CHOP regimen)significantly decreased the risk of disease relapse and progression in CD10-negative patients (P=0.001),Bcl-6-negative patients (P=0.01), and MUM-1-positive patients (P=0.003). The risk of disease relapse in patients with non-GCB subtype (P=0.002) also decreased. In contrast, patients with the opposite immunohistochemical marker expression profile and GCB subtype did not benefit from treatment with the R-CHOP regimen. In addition, non-GCB subtype patients had a significantly higher expression rate of Bcl-2 than GCB subtype patients (P=0.042). Although univariate analysis found that both Bcl-2-positive and-negative patients had significantly higher event-free survival rates with the R-CHOP regimen, only Bcl-2 positivity (P=0.004) maintained significance in the Cox regression analysis. We conclude that the addition of rituximab can significantly improve the prognosis of patients with non-GCB subtype DLBCL, which is closely related to the expression of CD10, Bcl-6, MUM-1, and Bcl-2. | Xiao-Hui He Bo Li Sheng Yang Ning Lu Xun Zhang Shuang-Mei Zou Ye-Xiong Li Yong-Wen Song Shan Zheng Mei Dong Sheng-Yu Zhou dian-Liang Yang Peng Liu Chang-Gong Zhang Yan Qin Feng-Yi Feng Yuan-Kai Shi | 2012 | Chinese Journal of Cancer2012,31,6: | 9 |
| 6 | Dynamic tensile properties and microstructural evolution of extruded EW75 magnesium alloy at high strain rates显示文摘The dynamic tensile properties and microstructural evolution of an extruded EW75 magnesium alloy deformed at ambient temperature and different high strain rates(from 1000 to 3000 s^(-1))along extrusion direction(ED)were investigated by Split Hopkinson Tension Bar(SHTB).The corresponding deformation mechanisms,texture evolution and microstructure changes were analyzed by optical microscope(OM),electron backscatter diffraction(EBSD)and transmission electron microscope(TEM).The results show that the extruded EW75 magnesium alloy along ED exhibits a conventional positive strain rate sensitivity that the dynamic flow stresses increase with in creasing strain rate.Texture measurements show that after dynamic tension,the initial weak texture of extruded EW75 magnesium alloy tansforms to a relatively strong<10-10>//ED texture with increasing strain rates.The microstructural analysis demonstrates that dislocation motion are main deformatin mode to accommodate dynamic tensile deformation at high strain rates.In addition,the interactions of dislocation-dislocation and dislocation-second phase lead to the in crease of flow stress and strain hardening with increasing strain rate. | Jincheng Yu Bo Song Dabiao Xia Xun Zeng Yuanding Huang Norbert Hort Pingli Mao Zheng Liu | 2020 | Journal of Magnesium and Alloys2020,8,3: | 7 |
| 7 | Changes in Activities of Glutamine Synthetase during Grain Filling and Their Relation to Rice Quality显示文摘Four japonica rice varieties differed in cooking and eating qualities were used in a pot experiment to study the relationship between the activities of glutamine synthetase during grain filling and rice quality. The activities of glutamine synthetase gradually increased and then declined as a single peak curve in the course of grain filling. The 15th day after heading was a turning point, before which the enzymatic activities in the inferior rice varieties with high protein content were higher than those in the superior rice varietie with low protein content, and after which it was converse. The activity of glutamine synthetase in grain was correlated with the taste meter value, peak viscosity and breakdown negatively at the early stage of grain filling whereas positively at the middle and late stages. Moreover, it was correlated with the protein content of rice grain and setback positively at the early stage and negatively at the middle and late stages. The correlation degree varied with the course of grain filling. From 15 days to 20 days after heading was a critical stage, in which the direction of correlation between the activity of glutamine synthetase and taste meter value and RVA properties of rice changed. | JIN Zheng xun QIAN Chun rong YANG Jing LIU Hai ying PIAO Zhong ze | 2007 | Rice science2007,14,3: | 6 |
| 8 | Dark matter direct search sensitivity of the PandaX-4T experiment显示文摘The Panda X-4T experiment, a 4-ton scale dark matter direct detection experiment, is being planned at the China Jinping Underground Laboratory. In this paper we present a simulation study of the expected background in this experiment. In a 2.8-ton fiducial mass and the signal region between 1-10 keV electron equivalent energy, the total electron recoil background is found to be 4.9 × 10^(-5) kg^(-1) d^(-1) keV^(-1). The nuclear recoil background in the same region is 2.8 × 10^(-7) kg^(-1) d^(-1) keV^(-1). With an exposure of 5.6 ton-years, the sensitivity of Panda X-4 T could reach a minimum spin-independent dark matter-nucleon cross section of 6 × 10^(-48) cm^2 at a dark matter mass of 40 Ge V/c^2. | HongGuang Zhang Abdusalam Abdukerim Wei Chen Xun Chen YunHua Chen XiangYi Cui BinBin Dong DeQing Fang ChangBo Fu Karl Giboni Franco Giuliani LinHui Gu XuYuan Guo ZhiFan Guo Ke Han ChangDa He ShengMing He Di Huang XingTao Huang Zhou Huang Peng Ji XiangDong Ji YongLin Ju ShaoLi Li Yao Li Heng Lin HuaXuan Liu JiangLai Liu YuGang Ma YaJun Mao KaiXiang Ni JinHua Ning XiangXiang Ren Fang Shi AnDi Tan AnQing Wang Cheng Wang HongWei Wang Meng Wang QiuHong Wang SiGuang Wang XiuLi Wang XuMing Wang Zhou Wang MengMeng Wu ShiYong Wu JingKai Xia MengJiao Xiao PengWei Xie BinBin Yan JiJun Yang Yong Yang ChunXu Yu JuMin Yuan JianFeng Yue Dan Zhang Tao Zhang Li Zhao QiBin Zheng JiFang Zhou Ning Zhou XiaoPeng Zhou | 2019 | Science China(Physics,Mechanics & Astronomy)2019,62,3: | 6 |
| 9 | Managing esophageal fistulae by endoscopic transluminal drainage in esophageal cancer patients with superior mediastinal sepsis after esophagectomy显示文摘The management of postoperative leaks into the mediastinum after esophagectomy remains a challenge. We describe our clinical management of this complication through endoscopic transluminal drainage. Between 2008 and 2011, 4 patients with esophageal squamous cell carcinoma (ESCC) who underwent McKeown-type esophagectomy with two-field lymphadenectomy experienced complicated anastomotic fistulae in the presence of superior mediastinal sepsis. All 4 patients underwent endoscopic transluminal drainage, and all survived. The mean healing period was 50 days (range, 31 to 58 days), the mean stay in the intensive care unit was 7.3 days (range, 1 to 18 days), and the mean hospital stay was 64.5 days (range, 49 to 70 days). Endoscopically guided transluminal drainage should be considered for ESCC patients with superior mediastinal fistulae after esophagectomy. | Yu-Zhen Zheng Shu-Qin Dai Hong-Bo Shan Xiao-Yan Gao Lan-Jun Zhang Xun Cao Jian-Fei Zhu Jun-Ye Wang | 2013 | Chinese Journal of Cancer2013,32,8: | 6 |

| 16 | Novel MAC protocol for terahertz ultra-high data-rate wireless networks显示文摘Due to having a large bandwidth to support Gbps-level data rate,terahertz communication attracts more and more attention in recent years.However,there are few medium access control(MAC)protocols for terahertz ultra-high data-rate wireless networks,which affects the research and application of terahertz communications.To address this problem and to achieve ultra-high data-rate wireless access with terahertz communication,a novel MAC protocol,called medium access control for terahertz communication(MAC-TC),is proposed.Through designing a new channel access scheme,a new superframe structure,and related key parameters,MAC-TC can support a maximum data rate up to 10 Gbit/s even higher.Theoretical analysis and simulation results show that our proposed MAC protocol realizes the function of medium access control and attains a maximum data rate of 18.3 Gbit/s,which is 2 times higher than 5.78 Gbit/s,the theoretical maximum data rate of IEEE 802.15.3c standard. | REN Zhi CAO Ya-nan ZHOU Xun ZHENG Yuan Chen Qian-bin | 2013 | The Journal of China Universities of Posts and Telecommunications2013,20,6: | 3 |
| 17 | Acrolein Aggravates Secondary Brain Injury After Intracerebral Hemorrhage Through Drp1-Mediated Mitochondrial Oxidative Damage in Mice显示文摘Clinical advances in the treatment of intracranial hemorrhage(ICH)are restricted by the incomplete understanding of the molecular mechanisms contributing to secondary brain injury.Acrolein is a highly active unsaturated aldehyde which has been implicated in many nervous system diseases.Our results indicated a significant increase in the level of acrolein after ICH in mouse brain.In primary neurons,acrolein induced an increase in mitochondrial fragmentation,loss of mitochondrial membrane potential,generation of reactive oxidative species,and release of mitochondrial cytochrome c.Mechanistically,acrolein facilitated the translocation of dynaminrelated protein 1(Drpl)from the cytoplasm onto the mitochondrial membrane and led to excessive mitochondrial fission.Further studies found that treatment with hydralazine(an acrolein scavenger)significantly reversed Drpl translocation and the morphological damage of mitochondria after ICH.In parallel,the neural apoptosis,brain edema,and neurological functional deficits induced by ICH were also remarkably alleviated.In conclusion,our results identify acrolein as an important contributor to the secondary brain injury following ICH.Meanwhile,we uncovered a novel mechanism by which Drpl-mediated mitochondrial oxidative damage is involved in acroleininduced brain injury. | Xun Wu Wenxing Cui Wei Guo Haixiao Liu Jianing Luo Lei Zhao Hao Guo Longlong Zheng Hao Bai Dayun Feng Yan Qu | 2020 | Neuroscience Bulletin2020,36,10: | 3 |
| 18 | Application of spline wavelet transform in differential of electroanalytical signal显示文摘Investigating characteristics of spline wavelet, we found that if the two-order spline function, the derivative function of the three-order B spline function, is used as the wavelet base function, the spline wavelet transform has both the property of denoising and that of differential. As a result, the relation between the spline wavelet transform and the differential was studied in theory. Experimental results show that the spline wavelet transform can well be applied to the differential of the electroanalytical signal. Compared with other kinds of wavelet transform, the spline wavelet transform has a characteristic of differential. Compared with the digital differentia] and simulative differential with electronic circuit, the spline wavelet transform not only can carry out denoising and differential for a signal, but also has the advantages of simple operation and small quantity of calculation, because step length, RC constant and other kinds of parameters need not be selected.

| 20 | Photonic integrated spiking neuron chip based on a self-pulsating DFB laser with a saturable absorber显示文摘We proposed and experimentally demonstrated a simple and novel photonic spiking neuron based on a distributed feedback(DFB)laser chip with an intracavity saturable absorber(SA).The DFB laser with an intracavity SA(DFBSA)contains a gain region and an SA region.The gain region is designed and fabricated by the asymmetric equivalentπ-phase shift based on the reconstruction-equivalent-chirp technique.Under properly injected current in the gain region and reversely biased voltage in the SA region,periodic self-pulsation was experimentally observed due to the Q-switching effect.The self-pulsation frequency increases with the increase of the bias current and is within the range of several gigahertz.When the bias current is below the self-pulsation threshold,neuronlike spiking responses appear when external optical stimulus pulses are injected.Experimental results show that the spike threshold,temporal integration,and refractory period can all be observed in the fabricated DFB-SA chip.To numerically verify the experimental findings,a time-dependent coupled-wave equation model was developed,which described the physics processes inside the gain and SA regions.The numerical results agree well with the experimental measurements.We further experimentally demonstrated that the weighted sum output can readily be encoded into the self-pulsation frequency of the DFB-SA neuron.We also benchmarked the handwritten digit classification task with a simple single-layer fully connected neural network.By using the experimentally measured dependence of the self-pulsation frequency on the bias current in the gain region as an activation function,we can achieve a recognition accuracy of 92.2%,which bridges the gap between the continuous valued artificial neural networks and spike-based neuromorphic networks.To the best of our knowledge,this is the first experimental demonstration of a photonic integrated spiking neuron based on a DFB-SA,which shows great potential to realizing large-scale multiwavelength photonic spiking neural network chips. | YUECHUN SHI SHUIYING XIANG XINGXING GUO YAHUI ZHANG HONGJI WANG DIANZHUANG ZHENG YUNA ZHANG YANAN HAN YONG ZHAO XIAOJUN ZHU XIANGFEI CHEN XUN LI YUE HAO | 2023 | Photonics Research2023,11,8: | 2 |
