| 1 | Focal adhesion protein Kindlin-2 regulates bone homeostasis in mice显示文摘Our recent studies demonstrate that the focal adhesion protein Kindlin-2 is critical for chondrogenesis and early skeletal development. Here, we show that deleting Kindlin-2 from osteoblasts using the 2.3-kb mouse Col1 a1-Cre transgene minimally impacts bone mass in mice, but deleting Kindlin-2 using the 10-kb mouse Dmp1-Cre transgene, which targets osteocytes and mature osteoblasts, results in striking osteopenia in mice. Kindlin-2 loss reduces the osteoblastic population but increases the osteoclastic and adipocytic populations in the bone microenvironment. Kindlin-2 loss upregulates sclerostin in osteocytes,downregulates β-catenin in osteoblasts, and inhibits osteoblast formation and differentiation in vitro and in vivo. Upregulation ofβ-catenin in the mutant cells reverses the osteopenia induced by Kindlin-2 deficiency. Kindlin-2 loss additionally increases the expression of RANKL in osteocytes and increases osteoclast formation and bone resorption. Kindlin-2 deletion in osteocytes promotes osteoclast formation in osteocyte/bone marrow monocyte cocultures, which is significantly blocked by an anti-RANKLneutralizing antibody. Finally, Kindlin-2 loss increases osteocyte apoptosis and impairs osteocyte spreading and dendrite formation.Thus, we demonstrate an important role of Kindlin-2 in the regulation of bone homeostasis and provide a potential target for the treatment of metabolic bone diseases. | Huiling Cao Qinnan Yan Dong Wang Yumei Lai Bo Zhou Qi Zhang Wenfei Jin Simin Lin Yiming Lei Liting Ma Yuxi Guo Yishu Wang Yilin Wang Xiaochun Bai Chuanju Liu Jian QFeng Chuanyue Wu Di Chen Xu Cao Guozhi Xiao | 2020 | Bone Research2020，8，1： | 8 |
| 2 | Famitinib in combination with concurrent chemoradiotherapy in patients with locoregionally advanced nasopharyngeal carcinoma: a phase 1, open-label, dose-escalation Study显示文摘Background:Famitinib is a tyrosine kinase inhibitor against multiple targets,including vascular endothelial growth factor receptor 2/3,platelet-derived growth factor receptor,and stem cell factor receptor(c-kit).Previous studies have demonstrated anti-tumour activities of famitinib against a wide variety of advanced-stage solid cancers.We aimed to determine the safety and efficacy of famitinib with concurrent chemoradiotherapy(CCRT)in patients with locoregionally advanced nasopharyngeal carcinoma(NPC).We also evaluated the feasibility of contrast-enhanced ultrasound(D-CEUS)as a predictor of early tumour response to famitinib and to correlate functional parameters with clinical efficacy.Methods:The trial was conducted in subjects with stage III or IVa-b NPC using a 3+3 design of escalating fami-tinib doses.Briefly,subjects received 2 weeks of famitinib monotherapy followed by 7 weeks of famitinib plus CCRT.D-CEUS of the neck lymph nodes was performed at day 0,8 and 15 after famitinib was administered before starting concurrent chemoradiotherapy.End points included safety,tolerability and anti-tumour activity.Results:Twenty patients were enrolled(six each for 12.5,16.5 and 20 mg and two for 25 mg).Two patients in the 25 mg cohort developed dose-limiting toxicities,including grade 4 thrombocytopenia and grade 3 hypertension.The most common grade 3/4 adverse events were leukopenia,neutropenia and radiation mucositis.D-CEUS tests showed that more than 60%of patients achieved a perfusion parameter response after 2 weeks taking famitinib alone,and the parameter response was associated with disease improvement.In the famitinib monotherapy stage,three patients(15%)showed partial responses.The complete response rate was 65%at the completion of treatment and 95%3 months after the treatment ended.After a median follow-up of 44 months,the 3-year progression-free survival(PFS)and distant metastasis-free survival were 70%and 75%,respectively.Subjects with a decrease of perfusion parameter response,such as peak intensity decreased at least 30%after 1 week of famitinib treatment,had higher 3-year PFS(90.9%vs.44.4%,95%CI 73.7%-100%vs.11.9%-76.9%,P<0.001)than those with an increase or a reduction of less than 30%.Conclusions:The recommended famitinib dose for phase II trial is 20 mg with CCRT for patients with local advanced NPC.D-CEUS is a reliable and early measure of efficacy for famitinib therapies.Further investigation is required to confirm the effects of famitinib plus chemoradiotherapy. | Qiuyan Chen Linquan Tang Na Liu Feng Han Ling Guo Shanshan Guo Jianwei Wang Huai Liu Yanfang Ye Lu Zhang Liting Liu Pan Wang Yingqin Li Qingmei He Xiaoqun Yang Qingnan Tang Yang Li YuJing Liang XueSong Sun Chuanmiao Xie Yunxian Mo Ying Guo Rui Sun Haoyuan Mo Kajia Cao Xiang Guo Musheng Zeng Haiqiang Mai Jun Ma | 2018 | Cancer Communications2018，38，1： | 6 |
| 3 | Bioresponsive micro-to-nano albumin-based systems for targeted drug delivery against complex fungal infections显示文摘As a typical human pathogenic fungus,Cryptococcus neoformans is a life-threatening invasive fungal pathogen with a worldwide distribution causing w700,000 deaths annually.Cryptococcosis is not just an infection with multi-organ involvement,intracellular survival and extracellular multiplication of the fungus also play important roles in the pathogenesis of C.neoformans infections.Because adequate accumulation of drugs at target organs and cells is still difficult to achieve,an effective delivery strategy is desperately required to treat these infections.Here,we report a bioresponsive micro-to-nano(MTN)system that effectively clears the C.neoformans in vivo.This strategy is based on our in-depth study of the overexpression of matrix metalloproteinase 3(MMP-3)in infectious microenvironments(IMEs)and secreted protein acidic and rich in cysteine(SPARC)in several associated target cells.In this MTN system,bovine serum albumin(BSA,a natural ligand of SPARC)was used for the preparation of nanoparticles(NPs),and then microspheres were constructed by conjugation with a special linker,which mainly consisted of a BSA-binding peptide and an MMP-3-responsive peptide.This MTN system was mechanically captured by the smallest capillaries of the lungs after intravenous injection,and then hydrolyzed into BSA NPs by MMP-3 in the IMEs.The NPs further targeted the lung tissue,brain and infected macrophages based on the overexpression of SPARC,reaching multiple targets and achieving efficient treatment.We have developed a size-tunable strategy where microspheres'shrink'to NPs in IMEs,which effectively combines active and passive targeting and may be especially powerful in the fight against complex fungal infections. | Liting Cheng Miao-Miao Niu Tong Yana Zhongyi Ma Kexin Huang Ling Yang Xin Zhong Chong Li | 2021 | Acta Pharmaceutica Sinica B2021，11，10： | 2 |

| 6 | Auricular vagus nerve acupressure for patients with emotional distress under the COVID-19 pandemic:A smartphone-based,randomized controlled trial显示文摘Objective: To confirm whether self-administered AVNA treatment is effective in improving emotional distressunder the COVID-19 pandemic.Methods: A smartphone-based online, randomized, controlled trial was designed from 26 February 2020 to 28April 2020 in four study sites, including Wuhan, Beijing, Shenyang, and Guangzhou of China. Local residentswho had considerable emotional distress with a score of the Hospital Anxiety and Depression Scale (HADS) ≥9 were recruited. Participants were randomly assigned to three times of AVNA (n = 191) per day, in morning,around noon, and in evening or usual care (UC, n = 215) once daily for 14 days. The primary outcome was theresponse rate, which was the proportion of participants whose Hospital Anxiety and Depression Scale (HADS)score reduced from baseline by ≥ 50%. The assessment was conducted at baseline, 3 days, and 14 days.Results: The AVNA group had a markedly higher response rate than the UC group at 3 days (35.6% vs. 24.9%,P = 0.02) and at 14 days (70.7% vs. 60.6%, P = 0.02). The AVNA group showed significantly greater reductionin scores of HADS at the two measurement points and BAI at 3 days (P ≤ 0.03), with average respective effectsize of 0.217 and 0.195. Participants with AVNA spent less time falling asleep and rated their sleep qualitybeing remarkably higher than those with UC at endpoint.Conclusion: During COVID-19 pandemic period, treatment with self-administrated AVNA was more effectivethan UC in reducing emotional distress of isolated populations. These findings support self-administered AVNAas a treatment option for patients with emotional distress under the COVID-19 pandemic or other emergentevents. | Peijing Rong Lei Wang Lingling Yu Junying Wang Yan Ma Liting Wang Suxia Li Chunzhi Tang Liming Lu Liang Li Jiazi Dong Jiliang Fang Liwei Hou Zongshi Qin Xiaolan Su Zhangjin Zhang | 2021 | TMR Modern Herbal Medicine2021，4，2： | 1 |

| 12 | Progress in oncolytic viruses modified with nanomaterials for intravenous application显示文摘In oncolytic virus(OV)therapy,a critical component of tumor immunotherapy,viruses selectively infect,replicate within,and eventually destroy tumor cells.Simultaneously,this therapy activates immune responses and mobilizes immune cells,thereby eliminating residual or distant cancer cells.However,because of OVs’high immunogenicity and immune clearance during circulation,their clinical applications are currently limited to intratumoral injections,and their use is severely restricted.In recent years,numerous studies have used nanomaterials to modify OVs to decrease virulence and increase safety for intravenous injection.The most commonly used nanomaterials for modifying OVs are liposomes,polymers,and albumin,because of their biosafety,practicability,and effectiveness.The aim of this review is to summarize progress in the use of these nanomaterials in preclinical experiments to modify OVs and to discuss the challenges encountered from basic research to clinical application. | Liting Chen Zhijun Ma Chen Xu Youbang Xie Defang Ouyang Shuhui Song Xiao Zhao Funan Liu | 2023 | Cancer Biology & Medicine2023，20，11： | 0 |
