| 1 | The global registry of COVID-19 clinical trials: indicating the design of traditional Chinese medicine clinical trials显示文摘Objective:To analyze the registration information of Corona Virus Disease 2019(COVID-19)related clinical trials from all the clinical trial registry accepted by the International Committee of Medical Journal Editors(ICMJE).Methods:All the database of ICMJE-accepted clinical trial registry platform were searched for COVID-19 related clinical trials that registered from December 8,2019 to February 19,2020.Results:All the database totally contained data of 209 COVID-19 related clinical trials,including 66(31.6%)traditional Chinese medicine(TCM)related studies and 143(68.4%)non-TCM related studies.176(84.2%)clinical trials were registered in ChiCTR,as 33(15.8%)were registered in ClinicalTrials.gov.There were 152(72.7%)intervention trials,including 9(4.3%in total)preventive trials,136(65.1%in total)therapeutic trials and 7(3.3%in total)convalescent trials.Conclusion:At the present stage,clinical studies are still aiming at exploring the effective treatment of COVID-19,and the existing treatments need more high-quality clinical evidence supporting.Traditional Chinese medicine may have played an important role in all stages of the epidemic preventing and control,and the enthusiasm of carrying out scientific research has also been greatly improved.The relevant policies of clinical trial registration should be popularized among researchers,including traditional Chinese medicine researchers.And the methodological quality of clinical trials’design urges improving. | Xuxu Wei Mengzhu Zhao Chen Zhao Xiaoyu Zhang Ruijin Qiu Yiyi Lin Yang Sun Manke Guan Hongcai Shang | 2020 | TMR Modern Herbal Medicine2020，3，3： | 1 |
| 2 | Electroacupuncture at Tianshu(ST25) and Zusanli(ST36) alleviates stress-induced irritable bowel syndrome in mice by modulating gut microbiota and corticotropin-releasing factor显示文摘OBJECTIVE: To investigate whether electroacupuncture(EA) at bilateral Tianshu(ST25) and Zusanli(ST36) acupoints could alleviate stress-induced irritable bowel syndrome(IBS) and evaluate its effect on gut microbiota and corticotropin-releasing factor(CRF). METHODS: Thirty C57BL/6 mice were randomly divided into the normal, water avoidance stress(WAS), and WAS+EA groups(10 mice per group). An experimental model of IBS was established by exposing the animals to WAS. The mice were treated with EA at the bilateral Tianshu(ST25) and Zusanli(ST36) acupoints. The abdominal withdrawal reflex test was conducted to evaluate visceral sensitivity in IBS. Gut microbiota was analyzed using 16S r RNA sequencing and analysis. The expression of CRF was determined using immuneofluorescence and quantitative real-time polymerase chain reaction. RESULTS: EA alleviated visceral hypersensitivity in a mouse model of WAS-induced IBS. It modulated the dysbiosis of gut microbiota induced by WAS. Moreover, it suppressed the WAS-induced overexpression of CRF in colon tissues. CONCLUSION: The findings of this study suggest that EA alleviated WAS-induced IBS via mechanisms possibly involving the modulation of the dysbiosis of gut microbiota and suppression of CRF expression. | SUN Mengzhu ZHANG Yujie SONG Yafang GUO Jing ZHAO Tingting WANG Yuhang PEI Lixia SUN Jianhua | 2022 | Journal of Traditional Chinese Medicine2022，42，5： | 1 |
| 3 | Enriched gestation activates the IGF pathway to evoke embryo-adult benefits to prevent Alzheimer’s disease显示文摘Background:Building brain reserves before dementia onset could represent a promising strategy to prevent Alzheimer’s disease(AD),while how to initiate early cognitive stimulation is unclear.Given that the immature brain is more sensitive to environmental stimuli and that brain dynamics decrease with ageing,we reasoned that it would be effective to initiate cognitive stimulation against AD as early as the fetal period.Methods:After conception,maternal AD transgenic mice(3×Tg AD)were exposed to gestational environment enrichment(GEE)until the day of delivery.The cognitive capacity of the offspring was assessed by the Morris water maze and contextual fear-conditioning tests when the offspring were raised in a standard environment to 7 months of age.Western blotting,immunohistochemistry,real-time PCR,immunoprecipitation,chromatin immunoprecipitation(ChIP)assay,electrophysiology,Golgi staining,activity assays and sandwich ELISA were employed to gain insight into the mechanisms underlying the beneficial effects of GEE on embryos and 7–10-month-old adult offspring.Results:We found that GEE markedly preserved synaptic plasticity and memory capacity with amelioration of hallmark pathologies in 7–10-m-old AD offspring.The beneficial effects of GEE were accompanied by global histone hyperacetylation,including those at bdnf promoter-binding regions,with robust BDNF mRNA and protein expression in both embryo and progeny hippocampus.GEE increased insulin-like growth factor 1(IGF1)and activated its receptor(IGF1R),which phosphorylates Ca^(2+)/calmodulin-dependent kinase IV(CaMKIV)at tyrosine sites and triggers its nuclear translocation,subsequently upregulating histone acetyltransferase(HAT)and BDNF transcription.The upregulation of IGF1 mimicked the effects of GEE,while IGF1R or HAT inhibition during pregnancy abolished the GEE-induced CaMKIV-dependent histone hyperacetylation and BDNF upregulation.Conclusions:These findings suggest that activation of IGF1R/CaMKIV/HAT/BDNF signaling by gestational environment enrichment may serve as a promising strategy to delay AD progression. | Enjie Liu Qiuzhi Zhou Ao-Ji Xie Mengzhu Li Shujuan Zhang Hezhou Huang Zhenyu Liuyang Yali Wang Bingjin Liu Xiaoguang Li Dongsheng Sun Yuping Wei Xiaochuan Wang Qun Wang Dan Ke Xifei Yang Ying Yang Jian-Zhi Wang | 2019 | Translational Neurodegeneration2019，8，1： | 1 |

| 5 | GTPase-activating protein TBC1D5 coordinates with retromer to constrain synaptic growth by inhibiting BMP signaling显示文摘Formation and plasticity of neural circuits rely on precise regulation of synaptic growth.At Drosophila neuromuscular junction(NMJ),Bone Morphogenetic Protein(BMP)signaling is critical for many aspects of synapse formation and function.The evolutionarily conserved retromer complex and its associated GTPase-activating protein TBC1D5 are critical regulators of membrane trafficking and cellular signaling.However,their functions in regulating the formation of NMJ are less understood.Here,we report that TBC1D5 is required for inhibition of synaptic growth,and loss of TBC1D5 leads to abnormal presynaptic terminal development,including excessive satellite boutons and branch formation.Ultrastructure analysis reveals that the size of synaptic vesicles and the density of subsynaptic reticulum are increased in TBC1D5mutant boutons.Disruption of interactions of TBC1D5 with Rab7 and retromer phenocopies the loss of TBC1D5.Unexpectedly,we find that TBC1D5 is functionally linked to Rab6,in addition to Rab7,to regulate synaptic growth.Mechanistically,we show that loss of TBC1D5 leads to upregulated BMP signaling by increasing the protein level of BMP type Ⅱ receptor Wishful Thinking(Wit)at NMJ.Overall,our data establish that TBC1D5 in coordination with retromer constrains synaptic growth by regulating Rab7 activity,which negatively regulates BMP signaling through inhibiting Wit level. | Xiu Zhou Guangming Gan Yichen Sun Mengzhu Ou Junhua Geng Jing Wang Xi Yang Shu Huang Da Jia Wei Xie Haihuai He | 2023 | Journal of Genetics and Genomics2023，50，3： | 0 |
| 6 | A biomimetic nanoplatform for customized photothermal therapy of HNSCC evaluated on patient-derived xenograft models显示文摘Cancer cell membrane(CCM)derived nanotechnology functionalizes nanoparticles(NPs)to recognize homologous cells,exhibiting translational potential in accurate tumor therapy.However,these nanoplatforms are majorly generated from fixed cell lines and are typically evaluated in cell line-derived subcutaneous-xenografts(CDX),ignoring the tumor heterogeneity and differentiation from inter-and intra-individuals and microenvironments between heterotopic-and orthotopic-tumors,limiting the therapeutic efficiency of such nanoplatforms.Herein,various biomimetic nanoplatforms(CCM-modified gold@Carbon,i.e.,Au@C-CCM)were fabricated by coating CCMs of head and neck squamous cell carcinoma(HNSCC)cell lines and patient-derived cells on the surface of Au@C NP.The generated Au@C-CCMs were evaluated on corresponding CDX,tongue orthotopic xenograft(TOX),immunecompetent primary and distant tumor models,and patient-derived xenograft(PDX)models.The Au@C-CCM generates a photothermal conversion efficiency up to 44.2% for primary HNSCC therapy and induced immunotherapy to inhibit metastasis via photothermal therapy-induced immunogenic cell death.The homologous CCM endowed the nanoplatforms with optimal targeting properties for the highest therapeutic efficiency,far above those with mismatched CCMs,resulting in distinct tumor ablation and tumor growth inhibition in all four models.This work reinforces the feasibility of biomimetic NPs combining modular designed CMs and functional cores for customized treatment of HNSCC,can be further extended to other malignant tumors therapy. | Qi Wu Lan Chen Xiaojuan Huang Jiayi Lin Jiamin Gao Guizhu Yang Yaping Wu Chong Wang Xindan Kang Yanli Yao Yujue Wang Mengzhu Xue Xin Luan Xin Chen Zhiyuan Zhang Shuyang Sun | 2023 | International Journal of Oral Science2023，15，1： | 0 |
| 7 | Electroacupuncture alleviates water avoidance stress-induced irritable bowel syndrome in mice by improving intestinal barrier functions and suppressing the expression of inflammatory cytokines显示文摘OBJECTIVE:To evaluate the effects and related mechanisms of electroacupuncture(EA)on irritable bowel syndrome(IBS).METHODS:Male C57BL/6 mice were randomly allocated into normal,model,and EA groups.Experimental IBS mice models were established by exposure to water avoidance stress(WAS).Mice in the EA group were treated with EA at bilateral Tianshu(ST 25)and Zusanli(ST 36)for 7 consecutive days,15 min each day.Abdominal withdrawal reflex(AWR)tests and intestinal motility tests were performed to evaluate visceral sensitivity and intestinal motility of mice.Expression levels of tight junction proteins(TJPs)and inflammatory cytokines in colon tissues were determined through immunofluorescence,real-time polymerase chain reactions(PCR)and Western blot assays.RESULTS:EA alleviated visceral hypersensitivity and intestinal hypermotility in WAS-induced IBS mice.Moreover,EA promoted the expression of zonula occludens(ZO)-1,claudin-1,and occludin while suppressing the expression of interleukin(IL)-8,interferon(IFN)-γ,and tumor necrosis factor(TNF)-αin water avoidance stress(WAS)-induced irritable bowel syndrome(IBS)mice.CONCLUSION:EA alleviated WAS-induced IBS in mice by promoting intestinal barrier functions and suppressing the expression of inflammatory cytokines. | SUN Mengzhu ZHANG Yujie SONG Yafang GUO Jing WANG Yuhang XIN Chen GU Dongmei SUN Jianhua PEI Lixia | 2023 | Journal of Traditional Chinese Medicine2023，43，3： | 0 |
| 8 | Manipulating high-temperature superconductivity by oxygen doping in Bi_(2)Sr_(2)CaCu_(2)O_(8)+δ thin flakes显示文摘Harnessing the fascinating properties of correlated oxides requires precise control of their carrier density.Compared to other methods,oxygen doping provides an effective and more direct way to tune the electronic properties of correlated oxides.Although several approaches,such as thermal annealing and oxygen migration,have been introduced to change the oxygen content,a continuous and reversible solution that can be integrated with modern electronic technology is much in demand.Here,we report a novel ionic field-effect transistor using solid Gd-doped CeO_(2)as the gate dielectric,which shows a remarkable carrier-density-tuning ability via electric-field-controlled oxygen concentration at room temperature.In Bi_(2)Sr_(2)CaCu_(2)O_(8+δ))thin flakes,we achieve a reversible superconductor–insulator transition by driving oxygen ions in and out of the samples with electric fields,and map out the phase diagram all the way from the insulating regime to the over-doped superconducting regime by continuously changing the oxygen doping level.Scaling analysis indicates that the reversible superconductor–insulator transition for the Bi-2212 thin flakes follows the theoretical description of a two-dimensional quantum phase transition.Our work provides a route for realizing electric-field control of phase transition in correlated oxides.Moreover,the configuration of this type of transistor makes heterostructure/interface engineering possible,thus having the potential to serve as the next-generation all-solid-state field-effect transistor. | Bin Lei Donghui Ma Shihao Liu Zeliang Sun Mengzhu Shi Weizhuang Zhuo Fanghang Yu Genda Gu Zhenyu Wang Xianhui Chen | 2022 | National Science Review2022，9，10： | 0 |
