| 2 | Injectable hydrogels for cartilage and bone tissue engineering显示文摘Tissue engineering has become a promising strategy for repairing damaged cartilage and bone tissue. Among the scaffolds for tissue-engineering applications, injectable hydrogels have demonstrated great potential for use as three-dimensional cell culture scaffolds in cartilage and bone tissue engineering, owing to their high water content, similarity to the natural extracellular matrix(ECM), porous framework for cell transplantation and proliferation, minimal invasive properties, and ability to match irregular defects. In this review, we describe the selection of appropriate biomaterials and fabrication methods to prepare novel injectable hydrogels for cartilage and bone tissue engineering. In addition, the biology of cartilage and the bony ECM is also summarized. Finally, future perspectives for injectable hydrogels in cartilage and bone tissue engineering are discussed. | Mei Liu Xin Zeng Chao Ma Huan Yi Zeeshan Ali Xianbo Mou Song Li Yan Deng Nongyue He | 2017 | Bone Research2017，5，2： | 54 |

| 4 | Intracoronary arterial retrograde thrombolysis with percutaneous coronary intervention: a novel use of thrombolytic to treat acute ST-segment elevation myocardial infarction显示文摘Background Clearance of coronary arterial thrombosis is necessary in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing urgent percutaneous coronary intervention (PCI). There is currently no highly-recommended method of thrombus removal during interventional procedures. We describe a new method for opening culprit vessels to treat STEMI: intracoronary arterial retrograde thrombolysis (ICART) with PCI. Methods & Results Eight patients underwent ICART. The guidewire was advanced to the distal coronary artery through the occlusion lesion. Then, we inserted a microcatheter into the distal end of the occluded coronary artery over the guidewire. Urokinase (5–10 wu) mixed with contrast agents was slowly injected into the occluded section of the coronary artery through the microcatheter. The intracoronary thrombus gradually dissolved in 3–17 min, and the effect of thrombolysis was visible in real time. Stents were then implanted according to the characteristics of the recanalized culprit lesion to achieve full revascularization. One patient experienced premature ventricular contraction during vascular revascularization, and no malignant arrhythmias were seen in any patient. No reflow or slow flow was not observed post PCI. Thrombolysis in myocardial infarction flow grade and myocardial blush grade post-primary PCI was 3 in all eight patients. No patients experienced bleeding or stroke. Conclusions ICART was accurate and effective for treating intracoronary thrombi in patients with STEMI in this preliminary study. ICART was an effective, feasible, and simple approach to the management of STEMI, and no intraprocedural complications occurred in any of the patients. ICART may be a breakthrough in the treatment of acute STEMI. | Jin-Wen TIAN Mei ZHU Feng-Qi WANG Ke LI Chao-Fei ZHOU Bo LI Min WANG Jue-Lin DENG Bo JIANG Jing BAI Yi GUO Rong-Jie JIN Zhao ZHANG Ying LIN Ji-Hang WANG Shi-Hao ZHAO Ming-Zhi SHEN | 2019 | Journal of Geriatric Cardiology2019，16，6： | 22 |

| 7 | The growth mechanism of the basic magnesium chloride whisker显示文摘Based on the theoretical model of anion coordination polyhedron growth units, the growth mechanism of the basic magnesium chloride whisker was discussed in this paper.It was found that the basic magnesium chloride whisker habits were related to the different environments in which anion coordination polyhedra grew. The growth units of basic magnesium chloride whiskers are [Mg - (OH) 4]2 -and [Mg - Cl 4]2 -. The growth process is the incorporation process of growth units. Growth units will have different incorporations and orientations caused by different system characters or heating. Furthermore, the formation mechanism of basic magnesium chloride whiskers was also interpreted using anion coordination polyhedron growth units. | WU JianSong XIAO YingKai SU JingYun DENG TingTing FENG JieRong MO YuYing ZENG Mei | 2011 | Science China(Technological Sciences)2011，54，3： | 18 |

| 10 | Ciliary parathyroid hormone signaling activates transforming growth factor-βto maintain intervertebral disc homeostasis during aging显示文摘Degenerative disc disease(DDD) is associated with intervertebral disc degeneration of spinal instability. Here, we report that the cilia of nucleus pulposus(NP) cells mediate mechanotransduction to maintain anabolic activity in the discs. We found that mechanical stress promotes transport of parathyroid hormone 1 receptor(PTH1 R) to the cilia and enhances parathyroid hormone(PTH) signaling in NP cells. PTH induces transcription of integrin α_vβ_6 to activate the transforming growth factor(TGF)-β-connective tissue growth factor(CCN2)-matrix proteins signaling cascade. Intermittent injection of PTH(iPTH) effectively attenuates disc degeneration of aged mice by direct signaling through NP cells, specifically improving intervertebral disc height and volume by increasing levels of TGF-β activity, CCN2, and aggrecan. PTH1 R is expressed in both mouse and human NP cells. Importantly,knockout PTH1 R or cilia in the NP cells results in significant disc degeneration and blunts the effect of PTH on attenuation of aged discs. Thus, mechanical stress-induced transport of PTH1 R to the cilia enhances PTH signaling, which helps maintain intervertebral disc homeostasis, particularly during aging, indicating therapeutic potential of iPTH for DDD. | Liwei Zheng Yong Cao Shuangfei Ni Huabin Qi Zemin Ling Xin Xu Xuenong Zou Tianding Wu Ruoxian Deng Bo Hu Bo Gao Hao Chen Yusheng Li Jianxi Zhu Francis Tintani Shadpour Demehri Amit Jain Khaled M.Kebaish Shenghui Liao Cheryle A.Séguin Janet L.Crane Mei Wan Hongbin Lu Paul D.Sponseller Lee H.RileyIII Xuedong Zhou Jianzhong Hu Xu Cao | 2018 | Bone Research2018，6，3： | 13 |

| 13 | Insight-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 | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 12 |
| 14 | Dandelion polyphenols protect against acetaminophen-induced hepatotoxicity in mice via activation of the Nrf-2/HO-1 pathway and inhibition of the JNK signaling pathway显示文摘We investigated the liver protective activity of dandelion polyphenols(DP)against acetaminophen(APAP;Paracetamol)-induced hepatotoxicity.Mice were acclimated for 1 week and randomly divided into the following groups(n=9 per group):Control,APAP,APAP+DP(100 mg·kg^–1),APAP+DP(200 mg·kg^–1),and APAP+DP(400 mg·kg^–1)groups.Mice were pretreated with DP(100,200,and 400 mg·kg^–1)by oral gavage for 7 d before being treated with 350 mg·kg^–1 APAP for 24 h to induced hepatotoxicity.Severe liver injury was observed,and hepatotoxicity was analyzed after 24 h by evaluation of biochemical markers,protein expressions levels,and liver histopathology.Pretreatment with DP was able to restore serum liver characteristics(aspartate transaminase,AST;alanine aminotransferase,ALT;alkaline phosphatase,AKP),improve redox imbalance(superoxide dismutase,SOD;glutathione,GSH;malondialdehyde,MDA),and decrease inflammatory factors(tumor necrosis factor-α,TNF-α;interleukin-1β,IL-1β).Pretreatment with DP also significantly inhibited the expression levels of nitric oxide synthase(iNOS)and cyclooxygenase-2(COX-2).Furthermore,DP pretreatment could inhibit the apoptosis of liver cells caused by APAP through up-regulation of Bcl-2 and down-regulation of Bax and caspase-9 protein.DP also down-regulated p-JNK protein expression levels to inhibit APAP-induced mitochondrial oxidative stress and up-regulated the expression of Nrf-2 and its target gene HO-1.The histopathological staining demonstrated that DP pretreatment could inhibit APAP-induced hepatocyte infiltration,congestion,and necrosis.Our results demonstrate that DP pretreatment could protect against APAP-induced hepatic injury by activating the Nrf-2/HO-1 pathway and inhibition of the intrinsic apoptosis pathway. | REN Yong-Shen ZHENG Yao DUAN Huan LEI Lei DENG Xin LIU Xin-Qiao MEI Zhi-Nan DENG Xu-Kun | 2020 | Chinese Journal of Natural Medicines2020，18，2： | 11 |

| 16 | Side Effects during Treatment of Advanced Gastric Carcinoma by Chemotherapy Combined with CIK-cell Transfusion in Elderly People显示文摘OBJECTIVE To study the side effects and therapeutic results of autologous cytokine-induced killer(CIK)cell treatment in elderly patients with advanced gastric cancer. METHODS CIK cells were induced and cultured using biotechnics in vitro,and then the cells were infused back into the patients.Sixty elderly gastric cancer patients treated by chemotherapy(FOLFOX4 protocol)were followed-up.Among them,29 patients were treated with CIK cells during application of chemotherapy.Short-term curative effects and adverse events from the CIK transfusion and chemotherapy were observed. RESULTS Eight cases developed partial remission(PR),9 cases moderate remission(MR),7 cases stable disease(SD)and 5 cases progressive disease(PD).Out of a total of 29 patients who received chemotherapy combined with autologous CIK therapy, the total remission rate(PR+MR)was 58.6%.The total remission rate following chemotherapy alone was 45.2%,including 5 PR cases,9 MR cases,7 SD cases,and 10 PD cases.There was a relatively lower rate of severe chemotherapic toxicities in the CIK- cell transfusion group.Side e?ects of autologous CIK transfusion included chills(13 cases),fever(9 cases),nausea and vomiting (1 case)and general malaise(3 cases).Side effects were treated with conventional therapy resulting in their amelioration.No patients developed shock,blood capillary leakage syndrome,or abnormalities in routine blood,urine,liver and renal function tests. CONCLUSION Adoptive immunotherapy with autologous CIK cells may decrease the clinical signs and symptoms of elderly patients who suffer from advanced gastric cancer.Adverse reactions of patients can be alleviated by conventional therapy. Autologous CIK-cell transfusion may improve endurance to chemotherapy. | Jingting Jiang Changping Wu Liangrong Shi Ning Xu Haifeng Deng Mingyang Lu Mei Ji Hbei Zhu Xueguang Zhang | 2008 | Chinese Journal of Clinical Oncology2008，5，2： | 10 |
| 17 | The High Energy X-ray telescope (HE) onboard the Insight-HXMT astronomy satellite显示文摘The Insight-Hard X-ray Modulation Telescope(Insight-HXMT) is a broadband X-ray and γ-ray(1-3000 ke V) astronomy satellite. One of its three main telescopes is the High Energy X-ray telescope(HE). The main detector plane of HE comprises 18 Na I(Tl)/Cs I(Na) phoswich detectors, where Na I(Tl) is used as the primary detector to measure ~ 20-250 ke V photons incident from the field of view(FOV) defined by collimators, and Cs I(Na) is used as the active shielding detector to Na I(Tl) by pulse shape discrimination. Additionally, Cs I(Na) is used as an omnidirectional γ-ray monitor. The HE collimators have a diverse FOV,i.e. 1.1°×5.7°(15 units), 5.7°×5.7°(2 units), and blocked(1 unit). Therefore, the combined FOV of HE is approximately5.7°×5.7°. Each HE detector has a diameter of 190 mm resulting in a total geometrical area of approximately 5100 cm2, and the energy resolution is ~15% at 60 ke V. For each recorded X-ray event by HE, the timing accuracy is less than 10 μs and the deadtime is less than 10 μs. HE is used for observing spectra and temporal variability of X-ray sources in the 20-250 ke V band either by pointing observations for known sources or scanning observations to unveil new sources. Additionally, HE is used for monitoring the γ-ray burst in 0.2-3 Me V band. This paper not only presents the design and performance of HE instruments but also reports results of the on-ground calibration experiments. | CongZhan Liu YiFei Zhang XuFang Li XueFeng Lu Zhi Chang ZhengWei Li AiMei Zhang YongJie Jin HuiMing Yu Zhao Zhang MinXue Fu YiBao Chen JianFeng Ji YuPeng Xu JingKang Deng RenCheng Shang GuoQing Liu FangJun Lu ShuangNan Zhang YongWei Dong TiPei Li Mei Wu YanGuo Li HuanYu Wang BoBing Wu YongJie Zhang Zhi Zhang ShaoLin Xiong Yuan Liu Shu Zhang HongWei Liu YiJung Yang Fan Zhang | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，4： | 9 |

| 19 | Sequence-stratigraphic frameworks and their palaeogeographic patterns for the Permian Lopingian of the Dianqiangui Basin and its adjacent areas of Southwestern China显示文摘The Permian Lopingian in the Dianqiangui Basin and its adjacent areas is marked by the coal measures of the Wuchiapingian and the carbonate strata of the Changhsingian stages. For the Lopingian of the Dianqiangui Basin and its adjacent areas,the diversity of sedimentary facies and the obviousness of facies change provide an advantaged condition on a study of sequence stratigraphy. Approximately,the Wuchiapingian stage constitutes a third-order sequence and the Changhsingian stage forms an-other. For the Wuchiapingian stage in the study area,coal-measures were developed on the attached platform and,in addition,a special coal-measure that is composed of both limestone beds and coal beds was also developed in the central part of some isolated platforms. Grain-bank grainstones and packstones were formed on the margin of the attached platform as well as in the windward part of iso-lated platforms. For the Changhsingian stage in the study area,open-platform limestones were formed on the attached platform,while sponge-reef limestones were developed both on the margin of the at-tached platform and on the isolated platforms. The Lopingian Series is a set of basin-facies muddy shales with interbeds of silicalites in the inter-platform basin,which appears a set of the large-thick coarse clastic strata of molasses covering direct the deep-water strata from the Devonian to the Per-mian Yangsingian in the Qinzhou-Fangcheng region in the southern part of the study area. All of these features indicate the complexity of temporal-spatial facies-changes. Sequence-stratigraphic frame-works could be established,which would illustrate two types of facies-changing surfaces and dia-chronisms in the stratigraphic records,based on the combination of both biostratigraphic and chronostratigraphic materials and the regularity reflected by temporal evolutionary succession of sediments as well as spatial distributional patterns of sedimentary facies. Ultimately,features of sedi-mentary succession and palaeogeographical evolution of the Permian Lopingian in the study area are revealed clearly in a series of the panel diagrams of sequence-stratigraphic frameworks and the outline maps showing the sedimentary-facies and palaeogeography. The Permian Lopingian formed by two third-order sequences differs from the stratigraphy of the same era characterized by the constant re-gression along Euramerica. Most specially,if the end-Guadalupian mass-extinction event is genetically related to a regressive event represented by the unconformity of the first episode of the Dongwumovement in the study area,the mass-extinction event at the turn from the Permian to the Triassic is genetically related to a rapid transgressive event re-flected by the drowning unconformity in the study area. These phenomena might reveal a complex rela-tionship between mass-extinction events and trans-gressive-regressive events. | MEI MingXiang MA YongSheng DENG Jun CHU HanMin ZHENG KuanBing | 2007 | Science China Earth Sciences2007，50，6： | 8 |
