| 3 | Efficacy of Sijunzi decoction(四君子汤) on limb weakness in spleen Qi deficiency model rats through adenosine monophosphate-activated protein kinase/unc-51 like autophagy activating kinase 1 signaling显示文摘OBJECTIVE:To investigate the efficacy of Sijunzi decoction(四君子汤)on limb weakness in a rat model of spleen Qi deficiency(SQD),and to study its effect on mitophagy in skeletal muscle through adenosine monophosphate-activated protein kinase(AMPK)/unc-51 like autophagy activating kinase 1(ULK1)signaling.METHODS:SQD model rats were produced by fasting combined with forced swimming method for15 d.After model assessment,rats were randomly divided into four groups of 10[low/middle/high(L/M/H)Sijunzi decoction dose groups and a normal saline(S)group].Limb holding power(HP)and body mass(BM)were measured after 2 weeks of treatment.Following euthanasia,quadriceps femoris were dissected and myofiber and mitochondrial morphology were observed by transmission electron microscopy(TEM).Mitochondrial membrane potential(MMP),adenosine triphosphatase(ATP)and reactive oxygen species(ROS)levels were determined using colorimetric methods,and immunoblot analysis of Microtubule-associated protein light chain 3(LC3)and Sequestosome 1(p62)was performed to monitor mitophagy and AMPK/ULK1 signaling.RESULTS:Compared with control(C)group rats,in the S group,HP was reduced,the myofiber Z line was disordered,mitochondria were scattered,and numerous vacuoles and mitophagy were observed.MMP and ATP levels were reduced,ROS levels were elevated,and LC3B expression,and p-AMPKα(Thr172)/AMPKα,p-ULK1(Ser555)/ULK1,and p-Raptor(Ser792)/Raptor ratios were increased,while p62 expression and p-mT OR(Ser2448)/mT OR and p-ULK1(Ser757)/ULK1 ratios were decreased.After treatment,compared with the S group,HP was improved in M and H groups but not in the L group.Mitophagy was reduced in M,H and L groups but the Z line was disordered and vacuolization remained in the L group.ATP levels were elevated in M,H and L groups,and MMPs were elevated in M and H groups but not in the L group.ROS levels were decreased in M,H and L groups,as were LC3B expression and p-Raptor(Ser792)/Raptor ratios,while p62 expression and p-mT OR(Ser2448)/mT OR and p-ULK1(Ser757)/ULK1 ratios were increased in M and H groups but not in the L group.p-AMPKα(Thr172)/AMPKαand p-ULK1(Ser555)/ULK1 ratios were decreased in M,H and L groups.CONCLUSIONS:Sijunzi decoction improved HP,possibly by inhibiting mitophagy via suppression of AMPK/ULK1 signaling.This restored mitochondrial morphology and improved oxidative phosphorylation,which contributed to recovery of limb weakness in SQD model rats. | LIU Wenjun XU Xinzhu DUAN Zhiyuan LIANG Xicai MA Dan LI Gege XIE Xin CHAI Jiyan CHEN Jing SHAN Dehong | 2021 | Journal of Traditional Chinese Medicine2021，41，4： | 2 |

| 5 | antitumor activity in bortezomib-resistant multiple myeloma cells through inhibition of JAK2/STAT3 pathway显示文摘Multiple myeloma(MM),the second most common haematological malignancy,is currently incurable because patients often develop multiple drug resistance and experience subsequent relapse of the disease.This study aims to identify a potential therapeutic agent that can counter bortezomib(BTZ)resistance in MM.DCZ0358,a novel alkaloid compound,is found to exert potent cytotoxic effects against BTZ-resistant MM cells in vivo and in vitro.The antimyeloma activity of DCZ0358 is associated with inhibition of cell proliferation,promotion of cell apoptosis via caspase-mediated apoptotic pathways,and induction of G0/G1 phase arrest via downregulation of cyclin D1,CDK4,and CDK6.Further investigation of the molecular mechanism shows that DCZ0358 suppresses the JAK2/STAT3 signaling pathway.In conclusion,DCZ0358 can successfully counter BTZ resistance in MM cells.This study provides evidence that warrants future preclinical assessments of DCZ0358 as a therapeutic agent against BTZ resistance in MM. | Bibo Zhang Bo Li Yongsheng Xie Shuaikang Chang Zhijian Xu Huifang Hu Gege Chen Ting Zhang Jun He Xiaosong Wu Huabin Zhu Weiming Lai Dongliang Song Ying Lu Xinyan Jia Weiliang Zhu Jumei Shi | 2023 | Acta Biochimica et Biophysica Sinica2023，55，2： | 0 |
| 6 | A novel silicone derivative of natural osalmid(DCZ0858)induces apoptosis and cell cycle arrest in diffuse large B-cell lymphoma via the JAK2/STAT3 pathway显示文摘Diffuse large B-cell lymphoma(DLBCL)is a highly heterogeneous malignant tumor characterized by diffuse growth.DCZ0858 is a novel small molecule with excellent antitumor effects in DLBCL.This study explored in depth the inhibitory effect of DCZ0858 on DLBCL cell lines.Cell Counting Kit-8(CCK-8)and plate colony formation assays were used to evaluate cell proliferation levels.Flow cytometry was employed to analyze apoptosis and the cell cycle,and western blotting was used to quantify the expression of cell cycle regulators.The results indicated that DCZ0858 inhibited cell growth in a concentration-dependent and time-dependent manner while inducing no significant toxicity in normal cells.Moreover,DCZ0858 initiated cell apoptosis via both internal and external apoptotic pathways.DCZ0858 also induced cell cycle arrest in the G0/G1 phase,thereby controlling cell proliferation.Further investigation of the molecular mechanism showed that the JAK2/STAT3 pathway was involved in the DCZ0858-mediated antitumor effects and that JAK2 was the key target for DCZ0858 treatment.Knockdown of JAK2 partly weakened the DCZ0858-mediated antitumor effect in DLBCL cells,while JAK2 overexpression strengthened the effect of DCZ0858 in DLBCL cells.Moreover,a similar antitumor effect was observed for DCZ0858 and the JAK2 inhibitor ruxolitinib,and combining the two could significantly enhance cancer-suppressive signaling.Tumor xenograft models showed that DCZ0858 inhibited tumor growth in vivo and had low toxicity in important organs,findings that were consistent with the in vitro data.In summary,DCZ0858 is a promising drug for the treatment of DLBCL. | Kang Lu Bo Li Hui Zhang Zhijian Xu Dongliang Song Lu Gao Haiguo Sun Liping Li Yingcong Wang Qilin Feng Gege Chen Liangning Hu Rong Wei Yongsheng Xie Dandan Yu Xiaosong Wu Weiliang Zhu Jumei Shi | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 0 |
| 7 | Quantifying spatial distribution of interrill and rill erosion in a loess at different slopes using structure from motion(SfM)photogrammetry显示文摘The spatial distribution of interrill and rill erosion is essential for unravelling soil erosion principles and the application of soil and water conservation practices.To quantify interrill and rill erosion and their spatial development,four 30-min rainfalls at 90 mm h^(-1)intensity were consecutively simulated on runoff plots packed with a loess at six slopes of 10°,15°,20°,25°,30°and 35°.The soil surface was measured using the structure from motion(SfM)photogrammetry upon each simulation run,and the runoff and sediment samples were collected and measured at every 10 min.Rills did not develop until the third simulation run.During the initial two runs,the lower third section was more severely eroded than the upper and middle thirds along the slope direction,yet the interrill erosion was statistically uniform from left to right.Rills tended to emerge by both sidewalls and in the lower portion in the third run.The corresponding rill erosion increased with slope from 10°to 20°and then decreased for the slopes steeper,which was consistent with the slope trend of the sediment yield directly measured.The rills expanded substantially primarily via head retreat and to a lesser extent via sideward erosion after receiving another 30-min rainfall.Rill erosion contributed 69.3%of the total erosion loss,and shifted the critical slope corresponding to the maximum loss from 20°to 25°.These findings demonstrate the significance of rill erosion not only in total soil loss but also in its relation to slope,as well as the effectiveness of SfM photogrammetry in quantifying interrill and rill erosion. | Tao He Yang Yang Yangzi Shi Xiaozhen Liang Suhua Fu Gege Xie Baoyuan Liu Yingna Liu | 2022 | International Soil and Water Conservation Research2022，10，3： | 0 |
