| 1 | Biocompatibility of bio-Mg-Zn alloy within bone with heart, liver, kidney and spleen显示文摘A magnesium-zinc alloy rod was implanted into the marrow cavity of the distal femur in New Zealand rabbits. The femur with the implanted alloy was compared with the contralateral femur in which a bone tunnel without implant was formed as a control. Degradation of the magnesium-zinc alloy was analyzed via X-ray, scanning electron microscopy, and element energy spectrum analysis. Serum magnesium, liver and kidney function tests, and myocardial enzymes were measured. Heart, liver, kidney and spleen were sectioned for pathological analysis, and the effects of the implanted material on the histology and function of important organs were analyzed. Magnesium-zinc alloy was resorbed from the bone marrow cavity of the femur; 87% of the alloy was degraded within 14 weeks after the surgery. There were no significant differences in serum magnesium, liver or kidney function tests, or myocardial enzymes be- fore the surgery and after degradation of the magnesium-zinc alloy. Histology of the heart, liver, kidney, and spleen did not change. This study demonstrated that magnesium-zinc alloy can be resorbed in bone, and that the degradation products have good biocompatibility with heart, liver, kidney, and spleen. | HE YaoHua TAO HaiRong ZHANG Yan JIANG Yao ZHANG ShaoXiang ZHAO ChangLi LI JiaNan ZHANG BeiLei SONG Yang ZHANG XiaoNong | 2009 | Chinese Science Bulletin2009，54，3： | 18 |
| 2 | Sintilimab versus docetaxel as second-line treatment in advanced or metastatic squamous non-small-cell lung cancer:an open-label,randomized controlled phase 3 trial(ORIENT-3)显示文摘Background:Treatment options for Chinese patients with locally advanced or metastatic squamous-cell non-small-cell lung cancer(sqNSCLC)after failure of first-line chemotherapy are limited.This study(ORIENT-3)aimed to evaluate the efficacy and safety of sintilimab versus docetaxel as second-line treatment in patients with locally advanced or metastatic sqNSCLC.Methods:ORIENT-3 was an open-label,multicenter,randomized controlled phase 3 trial that recruited patients with stage IIIB/IIIC/IV sqNSCLC after failure with first-line platinum-based chemotherapy.Patients were randomized in a 1:1 ratio to receive either 200 mg of sintilimab or 75 mg/m^(2) of docetaxel intravenously every 3 weeks,stratified by the Eastern Cooperative Oncology Group performance status.The primary endpoint was overall survival(OS)in the full analysis set(FAS).Secondary endpoints included progression-free survival(PFS),objective response rate(ORR),disease control rate(DCR),duration of response(DoR)and safety.Results:Between August 25,2017,and November 7,2018,290 patients were randomized.For FAS,10 patients fromthe docetaxel armwere excluded.Themedian OS was 11.79(n=145;95%confidence interval[CI],10.28-15.57)months with sintilimab versus 8.25(n=135;95%CI,6.47-9.82)months with docetaxel(hazard ratio[HR]:0.74;95%CI,0.56-0.96;P=0.025).Sintilimab treatment significantly prolonged PFS(median 4.30 vs.2.79 months;HR:0.52;95%CI,0.39-0.68;P<0.001)and showed higher ORR(25.50%vs.2.20%,P<0.001)and DCR(65.50%vs.37.80%,P<0.001)than the docetaxel arm.The median DoRwas 12.45(95%CI,4.86-25.33)months in the sintilimab arm and 4.14(95%CI,1.41-7.23)months in the docetaxel arm(P=0.045).Treatment-related adverse events of grade≥3were reported in 26(18.1%)patients in the sintilimab arm and 47(36.2%)patients in the docetaxel arm.Exploratory biomarker analysis showed potential predictive values of expression levels of two transcription factors,including OVOL2(HR:0.35;P<0.001)and CTCF(HR:3.50;P<0.001),for sintilimab treatment.Conclusions:Compared with docetaxel,sintilimab significantly improved the OS,PFS,and ORR of Chinese patients with previously treated locally advanced or metastatic sqNSCLC. | Yuankai Shi Lin Wu Xinmin Yu Puyuan Xing Yan Wang Jianying Zhou Airong Wang Jianhua Shi Yi Hu Ziping Wang Guangyu An Yong Fang Sanyuan Sun Caicun Zhou Changli Wang Feng Ye Xingya Li Junye Wang Mengzhao Wang Yunpeng Liu Yanqiu Zhao Ying Yuan Jifeng Feng Zhendong Chen Jindong Shi Tao Sun Gang Wu Yongqian Shu Qisen Guo Yi Zhang Yong Song Shucai Zhang Yuan Chen Wei Li Hongrui Niu Wenwei Hu Lijun Wang Jianan Huang Yang Zhang Ying Cheng Zhengdong Wu Bo Peng Jiya Sun Christoph Mancao Yanqi Wang Luyao Sun | 2022 | Cancer Communications2022，42，12： | 8 |

| 4 | Site-Dependent Osseointegration of Biodegradable High-Purity Magnesium for Orthopedic Implants in Femoral Shaft and Femoral Condyle of New Zealand Rabbits显示文摘Magnesium(Mg) has been widely accepted as osteoconductive biomaterial, but osseointegration of Mg device at different implantation sites is still unclear. In the present study, high-purity magnesium(HP Mg)pins were implanted into femoral shaft and condyle of New Zealand rabbits concurrently. 2, 8, 12 and 16 weeks after surgery, rabbit femurs were harvested for micro-computed tomography(micro-CT) scanning and subsequent histological examinations. HP Mg pins were retrieved for scanning electron microscope and energy dispersive spectrum(SEM/EDS) analyses. HP Mg pins at both implantation sites performed stable corrosion with mineral deposition and bone incorporation on surface. However, difference in distribution of contact osteogenesis centers and biological properties of peri-implant bone tissues was detected between femoral shaft and femoral condyle. In femoral condyle, contact osteogenesis centers originated from both periosteum and cancellous bones and the whole HP Mg pin was encapsuled in trabecular bone at 16 weeks.Meanwhile, bone volume to total bone volume(BV/TV) and bone mineral density(BMD) of peri-implant bone tissues were above those of normal bone tissues. In femoral shaft, contact osteogenesis centers were only from periosteum and direct bone contact was confined in cortical bone, while BV/TV and BMD kept lower than normal. Furthermore, new formation of peri-implant bone tissues was more active in femoral condyle than in femoral shaft at 16 weeks. Therefore, although HP Mg performed good biocompatibility and corrosion behavior in vivo, its bioadaption of osseointegration at different implantations sites should be taken into consideration. Bone metaphysic was suitable for Mg devices where peri-implant bone tissues regenerated rapidly and the biological properties were close to normal bone tissues. | Pengfei Cheng Changli Zhao Pei Han Jiahua Ni Shaoxiang Zhang Xiaonong Zhang Yimin Chai | 2016 | Journal of Materials Science & Technology2016，32，9： | 4 |
| 5 | Full automorphism group of the generalized symplectic graph显示文摘Let Fq be a finite field of odd characteristic, m, ν the integers with 1≤m≤ν and Ka 2ν× 2ν nonsingular alternate matrix over Fq. In this paper, the generalized symplectic graph GSp2ν (q, m) relative to K over Fq is introduced. It is the graph with m-dimensional totally isotropic subspaces of the 2ν-dimensional symplectic space F(2ν)q as its vertices and two vertices P and Q are adjacent if and only if the rank of PKQT is 1 and the dimension of P ∩ Q is m-1. It is proved that the full automorphism group of the graph GSp2ν(q, m) is the projective semilinear symplectic group PΣp(2ν, q). | ZENG LiWei CHAI Zhao FENG RongQuan MA ChangLi | 2013 | Science China Mathematics2013，56，7： | 4 |
| 6 | Research of a novel biodegradable surgical staple made of high purity magnesium显示文摘Surgical staples made of pure titanium and titanium alloys are widely used in gastrointestinal anastomosis.However the Ti staple cannot be absorbed in human body and produce artifacts on computed tomography(CT)and other imaging examination,and cause the risk of incorrect diagnosis.The bioabsorbable staple made from polymers that can degrade in human body environment,is an alternative.In the present study,biodegradable high purity magnesium staples were developed for gastric anastomosis.U-shape staples with two different interior angles,namely original 90and modified 100,were designed.Finite element analysis(FEA)showed that the residual stress concentrated on the arc part when the original staple was closed to B-shape,while it concentrated on the feet for the modified staple after closure.The in vitro tests indicated that the arc part of the original staple ruptured firstly after 7 days immersion,whereas the modified one kept intact,demonstrating residual stress greatly affected the corrosion behavior of the HP-Mg staples.The in vivo implantation showed good biocompatibility of the modified Mg staples,without inflammatory reaction 9 weeks post-operation.The Mg staples kept good closure to the Anastomosis,no leaking and bleeding were found,and the staples exhibited no fracture or severe corrosion cracks during the degradation. | Hongliu Wu Changli Zhao Jiahua Ni Shaoxiang Zhang Jingyi Liu Jun Yan Yigang Chen Xiaonong Zhang | 2016 | Bioactive Materials2016，1，2： | 3 |
| 7 | High-purity magnesium pin enhances bone consolidation in distraction osteogenesis via regulating Ptch protein activating Hedgehog-alternative Wnt signaling显示文摘Magnesium alloys are promising biomaterials for orthopedic implants because of their degradability,osteogenic effects,and biocompatibility.Magnesium has been proven to promote distraction osteogenesis.However,its mechanism of promoting distraction osteogenesis is not thoroughly studied.In this work,a high-purity magnesium pin developed and applied in rat femur distraction osteogenesis.Mechanical test,radiological and histological analysis suggested that high-purity magnesium pin can promote distraction osteogenesis and shorten the consolidation time.Further RNA sequencing investigation found that alternative Wnt signaling was activated.In further bioinformatics analysis,it was found that the Hedgehog pathway is the upstream signaling pathway of the alternative Wnt pathway.We found that Ptch protein is a potential target of magnesium and verified by molecular dynamics that magnesium ions can bind to Ptch protein.In conclusion,HP Mg implants have the potential to enhance bone consolidation in the DO application,and this process might be via regulating Ptch protein activating Hedgehog-alternative Wnt signaling. | Musha Hamushan Weijie Cai Yubo Zhang Zun Ren Jiafei Du Shaoxiang Zhang Changli Zhao Pengfei Cheng Xiaonong Zhang Hao Shen Pei Han | 2021 | Bioactive Materials2021，6，6： | 3 |
| 8 | PtNi-W/C with Atomically Dispersed Tungsten Sites Toward Boosted ORR in Proton Exchange Membrane Fuel Cell Devices显示文摘The performance of proton exchange membrane fuel cells is heavily dependent on the microstructure of electrode catalyst especially at low catalyst loadings.This work shows a hybrid electrocatalyst consisting of PtNi-W alloy nanocrystals loaded on carbon surface with atomically dispersed W sites by a two-step straightforward method.Single-atomic W can be found on the carbon surface,which can form protonic acid sites and establish an extended proton transport network at the catalyst surface.When implemented in membrane electrode assembly as cathode at ultra-low loading of 0.05 mgPt cm^(−2),the peak power density of the cell is enhanced by 64.4%compared to that with the commercial Pt/C catalyst.The theoretical calculation suggests that the single-atomic W possesses a favorable energetics toward the formation of*OOH whereby the intermediates can be efficiently converted and further reduced to water,revealing a interfacial cascade catalysis facilitated by the single-atomic W.This work highlights a novel functional hybrid electrocatalyst design from the atomic level that enables to solve the bottle-neck issues at device level. | Huawei Wang Jialong Gao Changli Chen Wei Zhao Zihou Zhang Dong Li Ying Chen Chenyue Wang Cheng Zhu Xiaoxing Ke Jiajing Pei Juncai Dong Qi Chen Haibo Jin Maorong Chai Yujing Li | 2023 | Nano-Micro Letters2023，15，9： | 3 |
| 9 | Increased osteoblast adhesion on nanophase Ti6Al4V显示文摘The objective of the present study was to prepare a novel nanostructured surface of Ti6Al4V alloy by the severe plastic deformation (SPD) and the chemical treatment process and to evaluate the adhesion of osteoblast on the nanophase titanium alloy. In the in vitro study, the primary cultured osteoblasts of neonatal rat calvaria were cultured on the nanophase and the as-received smooth Ti6Al4V substrates. Then osteoblasts adhesion behaviors on different substrates were observed by the fluorescence mi-croscopy, scanning electron microscopy (SEM) and RT-PCR analysis. The results of our research showed increased osteoblast adhesion on the nanophase titanium alloy compared with the as-received case. On the nanophase substrate, the presence of extensive filopodia, strong cellular adhesion and early cellular confluency could be observed. In addition, the expression of the adhesion-related integrin β1 mRNA was also higher on the nanophase substrate. It suggested that the nano technology could be further considered for orthopedic implant applications. | JI WeiPing HAN Pei ZHAO ChangLi JIANG Yao ZHANG XiaoNong | 2008 | Chinese Science Bulletin2008，53，11： | 3 |
| 10 | Comparative Study about Degradation of High-purity Magnesium Screw in Intact Femoral Intracondyle and in Fixation of Femoral Intracondylar Fracture显示文摘Bone screws encounter complex mechanical environment in fracture fixation of weight-bearing bone.In the present study, high-purity magnesium(HP Mg) screws were applied in fixation of rabbit femoral intracondylar fracture with 3 mm gap. In the control group, HP Mg screws of the same design were implanted at corresponding position of contralateral leg. At 4, 8 and 16 weeks after surgery, retrieved femurs went through micro-computed tomography(micro-CT) scanning and hard tissue processing. Under mechanical stress involved in fracture fixation, bending of screw bolt was observed at the portion exposed to facture gap at 4 weeks. Then local corrosion at the same portion was detected 16 weeks after surgery,which indicated the accumulation effect of mechanical stress on Mg corrosion. HP Mg screws in the fracture group had no significant difference with the control group in screw volume, surface area, surfaceto-volume ratio(S/V). And peri-implant bone volume/tissues volume(BV/TV) and bone volume density(BMD) in the fracture group was comparable to that in the control group. Furthermore, histological analysis showed new formed bone tissues in fracture gap and fracture healing 16 weeks after surgery. Under mechanical stress, HP Mg screw suffered bolt bending and local corrosion at the portion exposed to fracture gap. But it had no influence on the integral corrosion behaviors, osseointegration of HP Mg screw and the fracture healing. Therefore, HP Mg screws possessed good potential in fracture fixation of weightbearing bones. | Pei Han Pengfei Cheng Changli Zhao Shaoxiang Zhang Runhua Zhou Xiaonong Zhang Yimin Chai | 2017 | Journal of Materials Science & Technology2017，33，3： | 2 |
| 11 | Study of Cell Behaviors on Anodized TiO_2 Nanotube Arrays with Coexisting Multi-Size Diameters显示文摘It has been revealed that the different morphologies of anodized TiO_2 nanotubes, especially nanotube diameters, triggered different cell behaviors. However, the influence of TiO_2 nanotubes with coexisting multi-size diameters on cell behaviors is seldom reported. In this work, coexisting four-diameter TiO_2 nanotube samples, namely,one single substrate with the integration of four different nanotube diameters(60, 150, 250, and 350 nm), were prepared by repeated anodization. The boundaries between two different diameter regions show well-organized structure without obvious difference in height. The adhesion behaviors of MC3T3-E1 cells on the coexisting fourdiameter TiO_2 nanotube arrays were investigated. The results exhibit a significant difference of cell density between smaller diameters(60 and 150 nm) and larger diameters(250 and 350 nm) within 24 h incubation with the coexistence of different diameters, which is totally different from that on the single-diameter TiO_2 nanotube arrays. The coexistence of four different diameters does not change greatly the cell morphologies compared with the singlediameter nanotubes. The findings in this work are expected to offer further understanding of the interaction between cells and materials. | Yifan Chen Jiahua Ni Hongliu Wu Ruopeng Zhang Changli Zhao Wenzhi Chen Feiqing Zhang Shaoxiang Zhang Xiaonong Zhang | 2016 | Nano-Micro Letters2016，8，1： | 2 |

| 18 | Treatment Strategy for Chylothorax after Resection for Lung Cancer—16 Case Report显示文摘OBJECTIVE To review the experience of iatrogenic chylothorax after pul- monary resections for lung cancer and to evaluate our treatment strategy. METHODS From July 1997 through December 2003, a total of 1,546 pa- tients underwent pulmonary resection (at least lobectomy) and systematic mediastinal lymph node dissection for lung cancer in our division. Sixteen patients had a postoperative chylothorax complication. All of these pa- tients in this study were conservatively treated (closed drainage) with complete oral intake cessation and total parenteral nutrition. RESULTS All patients had their condition cured with conservative treat- ment. The duration of the treatment was 6-21 days. The patients were given normal diet for a mean of 9.8 days after chylothorax diagnosis. CONCLUSION If the correct treatment strategy is selected, most cases of chylothorax after pulmonary resection with systematic mediastinal lymph node dissection can be cured with a conservative strategy. | Hongjing Jiang Changli Wang Zhenqing Zhao Xiaolin Li Doliong Qi Liqun Gong | 2006 | Chinese Journal of Clinical Oncology2006，3，3： | 1 |
