| 3 | Osteoarthritis:pathogenic signaling pathways and therapeutic targets显示文摘Osteoarthritis(OA)is a chronic degenerative joint disorder that leads to disability and affects more than 500 million population worldwide.OA was believed to be caused by the wearing and tearing of articular cartilage,but it is now more commonly referred to as a chronic whole-joint disorder that is initiated with biochemical and cellular alterations in the synovial joint tissues,which leads to the histological and structural changes of the joint and ends up with the whole tissue dysfunction.Currently,there is no cure for OA,partly due to a lack of comprehensive understanding of the pathological mechanism of the initiation and progression of the disease.Therefore,a better understanding of pathological signaling pathways and key molecules involved in OA pathogenesis is crucial for therapeutic target design and drug development.In this review,we first summarize the epidemiology of OA,including its prevalence,incidence and burdens,and OA risk factors.We then focus on the roles and regulation of the pathological signaling pathways,such as Wnt/β-catenin,NF-κB,focal adhesion,HIFs,TGFβ/ΒΜP and FGF signaling pathways,and key regulators AMPK,mTOR,and RUNX2 in the onset and development of OA.In addition,the roles of factors associated with OA,including MMPs,ADAMTS/ADAMs,and PRG4,are discussed in detail.Finally,we provide updates on the current clinical therapies and clinical trials of biological treatments and drugs for OA.Research advances in basic knowledge of articular cartilage biology and OA pathogenesis will have a significant impact and translational value in developing OA therapeutic strategies. | Qing Yao Xiaohao Wu Chu Tao Weiyuan Gong Mingjue Chen Minghao Qu Yiming Zhong Tailin He Sheng Chen Guozhi Xiao | 2023 | Signal Transduction and Targeted Therapy2023，8，3： | 11 |
| 4 | Repeatability and Reproducibility of Quantitative Assessment of the Retinal Microvasculature Using Optical Coherence Tomography Angiography Based on Optical Microangiography显示文摘Objective The aim of this study was to determine the repeatability and reproducibility of optical coherence tomography angiography(OCTA) based on optical microangiography(OMAG) measurements of macular vessels in normal eyes. Methods In this prospective cohort study, 40 eyes of 40 healthy volunteers underwent repeated OCTA(Cirrus HD-OCT 5000 angiography system, Carl Zeiss Meditec, Inc.) scans on two separate visit days. On each visit day, the eyes were scanned three times. The following parameters were used to quantitatively describe the OCTA images of the superficial vascular network: vessel area density(VAD), vessel skeleton density(VSD), vessel diameter index(VDI), vessel perimeter index(VPI), vessel complexity index(VCI), flux, and foveal avascular zone(FAZ). Coefficient of variation(CV) and intraclass correlation coefficient(ICC) were calculated for evaluating intravisit and intervisit repeatability, as well as interobserver reproducibility. Results The measurements showed high repeatability [CVs ≤ 4.2%(intravisit) and ≤ 4.6%(intervisit)] and interobserver reproducibility(ICCs ≥ 0.923) for all parameters. Conclusion This study demonstrated good repeatability and reproducibility of OCTA based on OMAG for the measurement of superficial vessel parameters in normal eyes. | ZHAO Qi YANG Wen Li WANG Xiao Na Ruikang K Wang YOU Qi Sheng CHU Zhong Di XIN Chen ZHANG Meng Yu LI Dong Jun WANG Zi Yang CHEN Wei LI Yi Feng CUI Rui SHEN Lin WEI Wen Bin | 2018 | Biomedical and Environmental Sciences2018，31，6： | 8 |

| 8 | miRNA-181 regulates embryo implantation in mice through targeting leukemia inhibitory factor显示文摘Embryo implantation is a crucial step in mammalian reproduction.However,little is known regarding the physiological roles of microRNAs in the regulation of embryo implantation.Here we show that a minimum uterine expression of miR-181 is essential for the onset of embryo implantation.Both transient and prolonged transgenic expression of miR-181 led to impaired implantation,which can be rescued by exogenous administration of leukemia inhibitory factor(LIF).Mechanistically,miR-181 is able to directly target LIF and downregulate LIF expression,thereby inhibiting embryo implantation.We also show that miR-181 expression is regu-lated by the transcriptional factor Emx2,and the Emx2–miR-181 axis plays an importantrole in regulating embryo implantation.Taken together,these results reveal a novel function of miR-181 in embryo implantation through the regulation of LIF,and also indicate a potential link between miR-181 dysregulation and human embryo implantation defects. | Bo Chu Liangwen Zhong Shuang Dou Jun Wang Jianmin Li Mingwei Wang Qinghua Shi Yide Mei Mian Wu | 2015 | Journal of Molecular Cell Biology2015，7，1： | 5 |

| 10 | Photostable and Biocompatible Fluorescent Silicon Nanoparticles for Imaging-Guided Co-Delivery of siRNA and Doxorubicin to Drug-Resistant Cancer Cells显示文摘The development of effective and safe vehicles to deliver small interfering RNA(siRNA) and chemotherapeutics remains a major challenge in RNA interference-based combination therapy with chemotherapeutics,which has emerged as a powerful platform to treat drug-resistant cancer cells.Herein,we describe the development of novel all-in-one fluorescent silicon nanoparticles(SiNPs)-based nanomedicine platform for imaging-guided co-delivery of siRNA and doxorubicin(DOX).This approach enhanced therapeutic efficacy in multidrug-resistant breast cancer cells(i.e.,MCF-7/ADR cells).Typically,the SiNP-based nanocarriers enhanced the stability of siRNA in a biological environment(i.e.,medium or RNase A) and imparted the responsive release behavior of siRNA,resulting in approximately 80% down-regulation of P-glycoprotein expression.Co-delivery of P-glycoprotein siRNA and DOX led to>35-fold decrease in the half maximal inhibitory concentration of DOX in comparison with free DOX,indicating the pronounced therapeutic efficiency of the resultant nanocomposites for drug-resistant breast cancer cells.The intracellular time-dependent release behaviors of siRNA and DOX were revealed through tracking the strong and stable fluorescence of SiNPs.These data provide valuable information for designing effective RNA interference-based co-delivery carriers. | Daoxia Guo Xiaoyuan Ji Fei Peng Yiling Zhong Binbin Chu Yuanyuan Su Yao He | 2019 | Nano-Micro Letters2019，11，2： | 5 |

| 12 | Toxoplasma gondii GRA15II effector-induced M1 cells ameliorate liver fibrosis in mice infected with Schistosomiasis japonica显示文摘Recent studies indicated that type II Toxoplasma gondii(Tg)GRA15II favored the generation of classically activated macrophages(M1),whereas type I/III TgROP16I/III promoted the polarization of alternatively activated macrophages(M2).A number of studies have demonstrated that M2 cells are involved in the pathogenesis of the liver fibrogenesis caused by Schistosoma japonicum.The purpose of the present study was to explore the inhibitory effect of Toxoplasma-derived TgGRA15II on mouse hepatic fibrosis with schistosomiasis.The gra15II and rop16I/III genes were amplified from strains T.gondii PRU and Chinese 1 Wh3,respectively.Lentiviral vectors containing the gra15II or rop16I/III plasmid were constructed and used to infect the RAW264.7 cell line.The polarization of the transfected cells was evaluated,followed by co-culture of the biased macrophages with mouse hepatic stellate JS1 cells.Then,mice were injected with GRA15II-driven macrophages via the tail vein and infected with S.japonicum cercariae.TgGRA15II induced a M1-biased response,whereas TgROP16I/III drove the macrophages to a M2-like phenotype.The in vitro experiments indicated that JS1 cell proliferation and collagen synthesis were decreased following co-culture with TgGRA15II-activated macrophages.Furthermore,mice inoculated with TgGRA15II-biased macrophages displayed a notable alleviation of collagen deposition and granuloma formation in their liver tissues.Our results suggest that TgGRA15II-induced M1 cells may dampen the M2 dominant pathogenesis of hepatic fibrosis and granulomatosis.These results provide insights into the use of parasite-derived immunomodulators as potential anti-fibrosis agents and to re-balance the schistosomiasis-induced immune response. | Yuanyuan Xie Huiqin Wen Ke Yan Shushu Wang Xuesong Wang Jian Chen Yuanling Li Yuanhong Xu Zhengrong Zhong Jilong Shen Deyong Chu | 2018 | Cellular & Molecular Immunology2018，15，2： | 4 |
| 13 | Effect of coal slurry on the corrosion of coal-mine equipment显示文摘The corrosion of coal mine equipment immersed in coal slurry is addressed. The corrosion of low carbon steel samples immersed in coal slurries of different concentrations (80, 130, and 180 g/L) prepared from coals of different rank (long-flame coal, meager lean coal, and anthracite) and different granularity (0.25-0.5 mm, 0.074-0.25 mm, and less than 0.074 mm particle size) was studied by the electrochemical method of polarization curve measurement, controlled potential sweeping, and continuous scanning. The results show that the corrosion rate in an anthracite slurry, where the coal has high coalification, is far greater than corrosion in a long-flame or a meager lean coal slurry. Furthermore the corrosion current, polarization current, and corrosion rate of low carbon steel become larger, and the polarizability becomes smaller, as the coal particle size decreases. The same trend is seen as the concentration of the coal slurry increases. | ZhangQi Xie Jingxuan Zhao Wei Bai Shasha Zhong Shiteng Chu Zhenfeng | 2011 | Mining Science and Technology2011，21，3： | 4 |
| 14 | Human epidermal growth factor receptor 2 expression in mixed gastric carcinoma显示文摘AIM: To investigate human epidermal growth factor receptor 2(HER2) amplification and protein expression in mixed gastric carcinoma.METHODS: Fluorescence in situ hybridization and immunohistochemistry were used to detect HER2 amplification and protein expression in 277 cases of mixed gastric carcinoma. Protein staining intensity was rate as 1+, 2+, or 3+.RESULTS: Of the 277 cases, 114(41.2%) expressed HER2 protein. HER2 3+ staining was observed in 28/277(10.1%) cases, 2+ in 37/277(13.4%) cases, and 1+ in 49/277(17.7%) cases. A HER2 amplification rate of 17% was detected, of which 25/28(89.3%) were observed in the HER2 3+ staining group, 17/37(45.9%) in 2+, and 5/49(10.2%) in 1+. Of the 47 patients with HER2 amplification who received chemotherapy plus trastuzumab, 22 demonstrated median progression-free and overall survivals of 9.1 mo and 16.7 mo, respectively, which were significantly better than those achieved with chemotherapy alone(5.6 mo and 12.1 mo, respectively) in 19 previously treated patients(P s < 0.05). CONCLUSION: HER2 detection in mixed gastric carcinoma displays high heterogeneity. Relativelyquantitative parameters are needed for assessing the level of HER2 amplification and protein expression. | Yang-Kun Wang Zhong Chen Tian Yun Cong-Yang Li Bo Jiang Xue-Xia Lv Guang-Hui Chu Su-Nan Wang Hui Yan Lei-Feng Shi | 2015 | World Journal of Gastroenterology2015，21，15： | 4 |

| 16 | Biomineralized polymer matrix composites for bone tissue repair:a review显示文摘Bone defects caused by trauma, infection or bone tumor resection, are highly prevalent. A small number(5%–10%) of these injuries fail to heal due to non-union and require surgical intervention. Currently, the principal treatment options for these defects are autografts, allografts, xenografts or synthetic grafts. The main problems associated with these therapies include pain,infection and donor site morbidity. Bone tissue engineering is a diverse field that focuses on the regeneration of bone by combining cells, scaffolds, growth factors and dynamic forces. There have been many recent studies utilizing biomineralized polymer matrix composites which mimic the natural structure of bone. The principal focus of this review is on recent advances in the synthesis of various types of biomineralized polymer matrix composite. Examples of the biomineralization of naturallyderived and synthetic polymers widely used for bone engineering are also summarized. | Lin Zhong Ying Qu Kun Shi Bingyang Chu Minyi Lei Kangkang Huang Yingchun Gu Zhiyong Qian | 2018 | Science China Chemistry2018，61，12： | 4 |
