| 1 | Osteonecrosis of the femoral head: An update in year 2012显示文摘Osteonecrosis is a phenomenon involving disruption to the vascular supply to the femoral head, resulting in articular surface collapse and eventual osteoarthritis. Although alcoholism, steroid use, and hip trauma remain the most common causes, several other etiologies for osteonecrosis have been identified. Basic science research utilizing animal models and stem cell applications continue to further elucidate the pathophysiology of osteonecrosis and promise novel treatment options in the future. Clinical studies evaluating modern joint-sparing procedures have demonstrated significant improvements in outcomes, but hip arthroplasty is still the most common procedure performed in these affected younger adults. Further advances in joint-preserving procedures are required and will be widely studied in the coming decade. | Anjan P Kaushik Anusuya Das Quanjun Cui | 2012 | World Journal of Orthopedics2012,3,5: | 68 |

| 3 | Total hip arthroplasty in developmental dysplasia of the hip: Review of anatomy, techniques and outcomes显示文摘Total hip arthroplasty(THA) in developmental dysplasia of the hip(DDH) presents many challenges to the reconstructive surgeon. The complex femoral and acetabular anatomy makes standard reconstruction technically challenging. Acetabular coverage can be improved by medialization of the component or augmentation of the deficient areas with bone graft. Femoral shortening osteotomies are considered in cases of severe dysplasia and frankly dislocated hips. Each patient's unique anatomy dictates what options of reconstruction are available. The functional outcomes of THA in DDH are generally excellent, though higher rates of mechanical failure have been reported in this group. This article reviews the anatomy, classification, technical considerations, and outcomes of THA in patients with DDH. | Scott Yang Quanjun Cui | 2012 | World Journal of Orthopedics2012,3,5: | 21 |

| 6 | A review on 2D MoS_(2) cocatalysts in photocatalytic H_(2) production显示文摘Owing to their unique physicochemical,optical and electrical properties,two-dimensional(2D)MoS_(2) cocatalysts have been widely applied in designing and developing highly efficient composite photocatalysts for hydrogen generation under suitable light irradiation.In this review,we first elaborated on the fundamental aspects of 2D MoS_(2) cocatalysts to include the structural design principles,synthesis strategies,strengths and challenges.Subsequently,we thoroughly highlighted and discussed the modification strategies of 2D MoS_(2) H2-evolution cocatalysts,including doping heteroatoms(e.g.metals,non-metals,and co-doping),designing interfacial coupling morphologies,controlling the physical properties(e.g.thickness,size,structural defects or pores),exposing the reactive facets or edge sites,constructing cocatalyst heterojunctions,engineering the interfacial bonds and confinement effects.In the future,the forefront challenges in understanding and in precise controlling of the active sites at molecular level or atomic level should be carefully studied,while various potential mechanisms of photogenerated-electrons interactions should be proposed.The applications of MoS_(2) cocatalyst in the overall water splitting are also expected.This review may offer new inspiration for designing and constructing novel and efficient MoS_(2)-based composite photocatalysts for highly efficient photocatalytic hydrogen evolution. | Zizhan Liang Rongchen Shen Yun Hau Ng Peng Zhang Quanjun Xiang Xin Li | 2020 | Journal of Materials Science & Technology2020,56,21: | 12 |
| 7 | A chromosome-scale genome assembly of Isatis indigotica,an important medicinal plant used in traditional Chinese medicine显示文摘Isatis indigotica(2n=14)is an important medicinal plant in China.Its dried leaves and roots(called Isatidis Folium and Isatidis Radix,respectively)are broadly used in traditional Chinese medicine for curing diseases caused by bacteria and viruses such as influenza and viral pneumonia.Various classes of compounds isolated from this species have been identified as effective ingredients.Previous studies based on transcriptomes revealed only a few candidate genes for the biosynthesis of these active compounds in this medicinal plant.Here,we report a high-quality chromosome-scale genome assembly of I.indigotica with a total size of 293.88 Mb and scaffold N50=36.16 Mb using single-molecule real-time long reads and high-throughput chromosome conformation capture techniques.We annotated 30,323 highconfidence protein-coding genes.Based on homolog searching and functional annotations,we identified many candidate genes involved in the biosynthesis of main active components such as indoles,terpenoids,and phenylpropanoids.In addition,we found that some key enzyme-coding gene families related to the biosynthesis of these components were expanded due to tandem duplications,which likely drove the production of these major active compounds and explained why I.indigotica has excellent antibacterial and antiviral activities.Our results highlighted the importance of genome sequencing in identifying candidate genes for metabolite synthesis in medicinal plants. | Minghui Kang Haolin Wu Qiao Yang Li Huang Quanjun Hu Tao Ma Zaiyun Li Jianquan Liu | 2020 | Horticulture Research2020,7,1: | 9 |
| 8 | A review of UHMWPE wear-induced osteolysis:the role for early detection of the immune response显示文摘In a world where increasing joint arthroplasties are being performed on increasingly younger patients,osteolysis as the leading cause of failure after total joint arthroplasty(TJA) has gained considerable attention.Ultra-high molecular weight polyethylene wear-induced osteolysis is the process by which prosthetic debris mechanically released from the surface of prosthetic joints induces an immune response that favors bone catabolism, resulting in loosening of prostheses with eventual failure or fracture. The immune response initiated is innate in that it is nonspecific and self-propagating, with monocytic cells and osteoclasts being the main effectors. To date, detecting disease early enough to implement effective intervention without unwanted systemic side effects has been a major barrier. These barriers can be overcome using newer in vivo imaging techniques and modules linked with fluorescence and/or chemotherapies. We discuss the pathogenesis of osteolysis, and provide discussion of the challenges with imaging and therapeutics. We describe a positron emission tomography imaging cinnamoyl-Phe-(D)-Leu-Phe-(D)-Leu-Phe-Lys module,specific to macrophages, which holds promise in early detection of disease and localization of treatment.Further research and increased collaboration among therapeutic and three-dimensional imaging researchers are essential in realizing a solution to clinical osteolysis in TJA. | Adrese M Kandahari Xinlin Yang Kevin A Laroche Abhijit S Dighe Dongfeng Pan Quanjun Cui | 2016 | Bone Research2016,4,2: | 7 |

| 11 | Current concepts in management of femoroacetabular impingement显示文摘Femoroacetabular impingement(FAI)is an increasingly recognized condition,which is believed to contribute to degenerative changes of the hip.This correlation has led to a great deal of interested in diagnosis and treatment of FAI.FAI can be divided into two groups:cam and pincer type impingement.FAI can lead to chondral and labral pathologies,that if left untreated,can progress rapidly to osteoarthritis.The diagnosis of FAI involves a detailed history,physical exam,and radiographs of the pelvis.Surgical treatment is indicated in anatomic variants known to cause FAI.The primary goal of surgical treatment is to increase joint clearance and decrease destructive forces being transmitted through the joint.Treatment has been evolving rapidly over the past decade and includes three primary techniques:open surgical dislocation,mini-open,and arthroscopic surgery.Open surgical dislocation is a technique for dislocating the femoral head from the acetabulum with a low risk of avascular necrosis in orderto reshape the neck or acetabular rim to improve joint clearance.Mini-open treatment is performed using the distal portion of an anterior approach to the hip to visualize and to correct acetabular and femoral head and neck junction deformities.This does not involve frank dislocation.Recently,arthroscopic treatment has gained popularity.This however does have a steep learning curve and is best done by an experienced surgeon.Short-to mid-term results have shown relatively equal success with all techniques in patients with no or only mild evidence of degenerative changes.Additionally,all techniques have demonstrated low rates of complications. | Adam S Wilson Quanjun Cui | 2012 | World Journal of Orthopedics2012,3,12: | 4 |
| 12 | Design and application of active sites in g-C_(3)N_(4)-based photocatalysts显示文摘With the development in photocatalysis field,photocatalysts have received increasing attention due to their important role in environmental pollution and energy crisis.As a nonmetallic photocatalyst,graphitic carbon nitride(g-C3N4)has been widely recognized because of its excellent optical properties,low cost,and environment friendliness.In the g-C3N4 intrinsic frameworks,carbon atom tends to be the reducing active site,while nitrogen atom tends to be the oxidizing active site and reducing active site according to the difference of electronegativity.However,the quantity and quality of these active sites are affected by many factors,including C N covalent bonds,surface properties,etc.Active sites play an important role in photocatalysis;however,this role is not detailed in most reports.In this review,we proposed the following possible mechanisms of active sites in improving the photocatalytic activity of traditional g-C_(3)N_(4) based on its intrinsic:morphology regulation,carrier migration,surface active treatment,and substrate adsorption.The following factors affecting the active sites of g-C_(3)N_(4),including basal engineering and hybrid engineering,were also investigated.The roles of these active sites in improving the photocatalytic activity of g-C_(3)N_(4)-based photocatalytic materials,including morphology regulation,surface treatment,heteroatom doping,and interfacial interaction,were also expounded.Current challenges and future development of g-C_(3)N_(4)-based photocatalysts that are rich in active surface sites were also discussed.This review provides an in-depth understanding of g-C_(3)N_(4)-based photocatalysts. | Yang Li Xin Li Huaiwu Zhang Jiajie Fan Quanjun Xiang | 2020 | Journal of Materials Science & Technology2020,56,21: | 4 |

| 14 | Hybrid speciation via inheritance of alternate alleles of parental isolating genes显示文摘It is increasingly realized that homoploid hybrid speciation(HHS),which involves no change in chromosome number,is an important mechanism of speciation.HHS will likely increase in frequency as ecological and geographical barriers between species are continuing to be disrupted by human activities.HHS requires the establishment of reproductive isolation between a hybrid and its parents,but the underlying genes and genetic mechanisms remain largely unknown.In this study,we reveal by integrated approaches that reproductive isolation originates in one homoploid hybrid plant species through the inheritance of altemate alleles at genes that determine parental premating isolation.The parent species of this hybrid species are reproductively isolated by differences in flowering time and survivorship on soils containing high concentrations of iron.We found that the hybrid species inherits alleles of parental isolating major genes related to flowering time from one parent and alleles of major genes related to iron tolerance from the other parent.In this way,it became reproductively isolated from one parent by the difference in flowering time and from the other by habitat adaptation(iron tolerance).These findings and further modeling results suggest that HHS may occur relatively easily via the inheritance of alternate parental premating isolating genes and barriers. | Zefu Wang Yuanzhong Jiang Hao Bi Zhiqiang Lu Yazhen Ma Xiaoyue Yang Ningning Chen Bin Tian Bingbing Liu Xingxing Mao Tao Ma Stephen P.DiFazio Quanjun Hu Richard J.Abbott Jianquan Liu | 2021 | Molecular Plant2021,14,2: | 4 |

| 16 | Reducing costly falls after total knee arthroplasty显示文摘AIM To investigate whether adductor canal nerve block(ACB) reduces patient falls when compared to femoral nerve block(FNB) after total knee arthroplasty(TKA). METHODS We conducted an institutional review of all-cause falls after TKA from January 2013 to August 2016 using a quality improvement database. Our inclusion criteria were patients with diagnosis of primary knee osteoarthritis who underwent primary unilateral TKA with either a FNB or an ACB and sustained a fall during their hospitalization. We excluded patients who had revision TKA and extensor mechanism reconstruction. We also excluded patients with a history of post-traumatic arthritis, prior history of lower extremity fracture, history of neurological disease, or cerebrovascular disease. RESULTS A total of 834 patients had TKA with femoral nerve block and knee immobilizer(FNB + KI). Of those patients, 11(1.3%) experienced a fall during their hospital stay. In contrast, 791 patients had TKA with ACB. Of those patients, only one(0.13%) patient fall was recorded within this group. We used the Fisher's exact test to compare the differences between the two groups. The difference between the two groups achieves statistical significance(P = 0.006). We also found that 11 out of the 12 patients that fell had a right TKA procedure while one patient had a left TKA procedure. Nine out of twelve patients that fell were female, while only three patients were male.CONCLUSION Given the reduction in the number of falls with ACB, it is recommended that ACB be considered the preferred analgesia for patients undergoing a TKA procedure. | Surajudeen Adebola Bolarinwa Wendy Novicoff Quanjun Cui | 2018 | World Journal of Orthopedics2018,9,10: | 2 |
| 17 | Generation of rat blood vasculature and hematopoietic cells in rat-mouse chimeras by blastocyst complementation显示文摘Interspecies chimera through blastocyst complementation could be an alternative approach to create human organs in animals by using human pluripotent stem cells.A mismatch of the major histocompatibility complex of vascular endothelial cells between the human and host animal will cause graft rejection in the transplanted organs.Therefore,to achieve a transplantable organ in animals without rejection,creation of vascular endothelial cells derived from humans within the organ is necessary.In this study,to explore whether donor xeno-pluripotent stem cells can compensate for blood vasculature in host animals,we generated rat-mouse chimeras by injection of rat embryonic stem cells(rESCs)into mouse blastocysts with deficiency of Flk-1 protein,which is associated with endothelial and hematopoietic cell development.We found that rESCs could differentiate into vascular endothelial and hematopoietic cells in the rat-mouse chimeras.The whole yolk sac(YS)of Flk-1^EGFP/ECFP rat-mouse chimera was full of rat blood vasculature.Rat genes related to vascular endothelial cells,arteries,and veins,blood vessels formation process,as well as hematopoietic cells,were highly expressed in the YS.Our results suggested that rat vascular endothelial cells could undergo proliferation,migration,and self-assembly to form blood vasculature and that hematopoietic cells could differentiate into B cells,T cells,and myeloid cells in rat-mouse chimeras,which was able to rescue early embryonic lethality caused by Flk-1 deficiency in mouse. | Xiaomin Wang Hui Shi Juanjuan Zhou Qingjian Zou Quanjun Zhang Shixue Gou Pengfei Chen Lisha Mou Nana Fan Yangyang Suo Zhen Ouyang Chengdan Lai Quanmei Yan Liangxue Lai | 2020 | Journal of Genetics and Genomics2020,47,5: | 2 |

| 19 | Current evidence on potential of adipose derived stem cells to enhance bone regeneration and future projection显示文摘Injuries to the postnatal skeleton are naturally repaired through successive stepsinvolving specific cell types in a process collectively termed “bone regeneration”.Although complex, bone regeneration occurs through a series of well-orchestratedstages wherein endogenous bone stem cells play a central role. In most situations,bone regeneration is successful;however, there are instances when it fails andcreates non-healing injuries or fracture nonunion requiring surgical or therapeuticinterventions. Transplantation of adult or mesenchymal stem cells (MSCs) definedby the International Society for Cell and Gene Therapy (ISCT) as CD105+-CD90+CD73+CD45-CD34-CD14orCD11b-CD79αorCD19-HLA-DR- is beinginvestigated as an attractive therapy for bone regeneration throughout the world.MSCs isolated from adipose tissue, adipose-derived stem cells (ADSCs), aregaining increasing attention since this is the most abundant source of adult stemcells and the isolation process for ADSCs is straightforward. Currently, there isnot a single Food and Drug Administration (FDA) approved ADSCs product forbone regeneration. Although the safety of ADSCs is established from their usagein numerous clinical trials, the bone-forming potential of ADSCs and MSCs, ingeneral, is highly controversial. Growing evidence suggests that the ISCT definedphenotype may not represent bona fide osteoprogenitors. Transplantation of bothADSCs and the CD105- sub-population of ADSCs has been reported to induce bone regeneration. Most notably, cells expressing other markers such as CD146,AlphaV, CD200, PDPN, CD164, CXCR4, and PDGFRα have been shown torepresent osteogenic sub-population within ADSCs. Amongst other strategies toimprove the bone-forming ability of ADSCs, modulation of VEGF, TGF-β1 andBMP signaling pathways of ADSCs has shown promising results. The U.S. FDAreveals that 73% of Investigational New Drug applications for stem cell-basedproducts rely on CD105 expression as the “positive” marker for adult stem cells.A concerted effort involving the scientific community, clinicians, industries, andregulatory bodies to redefine ADSCs using powerful selection markers andstrategies to modulate signaling pathways of ADSCs will speed up thetherapeutic use of ADSCs for bone regeneration. | Quang Le Vedavathi Madhu Joseph M Hart Charles R Farber Eli R Zunder Abhijit S Dighe Quanjun Cui | 2021 | World Journal of Stem Cells2021,13,9: | 2 |
| 20 | Recent advances in crystalline carbon nitride for photocatalysis显示文摘Semiconductor photocatalytic technology has become one of the most important means to solve the current energy shortage and environmental pollution. Compared with the traditional photocatalysts, graphite carbon nitride has a wider range of light-harvesting and more stable physical and chemical properties. However, traditional thermally induced polymerization of nitrogen-containing precursors produces the melon-based carbon nitride solids with an amorphous or semi-crystalline structure, resulting in low conductivity and moderate photocatalytic activity. Recently, crystalline carbon nitride has attracted more and more attention in improving photocatalytic performance. Some significant progress regarding crystalline carbon nitride for the preparation of solar-fuel and environmental purification has also been made.This review describes the recent advances in the design and synthesis of crystalline carbon nitride photocatalysts. A brief description of the unique physical and chemical properties of crystalline carbon nitride was given. Later, the synthetic and modification strategies are being introduced. Then, the photocatalytic application of crystalline carbon nitride was discussed, mainly including photocatalytic H2 production,photocatalytic CO2 reduction, and photocatalytic degradation of pollutants. Finally, the challenges and future directions of crystalline carbon nitride photocatalysts are briefly introduced. | Jingjun Liu Wei Fu Yulong Liao Jiajie Fan Quanjun Xiang | 2021 | Journal of Materials Science & Technology2021,,32: | 2 |
