| 1 | ANTI-HYPOXIA AND ANTI-OXIDATION EFFECTS OF AMINOPHYLLINE ON HUMAN WITH ACUTE HIGH-ALTITUDE EXPOSURE显示文摘Objective To investigate the anti-hypoxia and anti-oxidation effects of aminophylline on human with acute high- altitude exposure. Methods Totally 100 young male army members newly recruited from Sichuan province (400 meters above sea level) were enrolled. They were randomly divided into two groups: 50 in aminophylline group (A group) and 50 in control group (C group). A group and C group orally took aminophylline and placebo respectively for 10 days, 7 days before entering Lhasa (3 658 meters above sea level) by air and 3 days after it. Several parameters were measured at three time points: before drug taken, 7 days after drug taken, and 3 days after ascending high altitude. These parameters included serum levels of nitric oxide (NO), superoxide dismutase (SOD), catalase (CAT), hydrogen dioxide (H2O2), lactic acid (LA), as well as arterial oxygen saturation (SO2), arterial oxygen partial pressure (PaO2), and arterial carbon dioxide partial pressure (PaCO2). Statistical analysis was conducted to compare the difference between two groups with Stata 7.0 software system. Results There were no statistical differences between groups in hypoxia and oxidation indicators before and after drug taken in plain area. Three days after ascending high altitude, the serum levels of SOD, CAT, H2O2, LA, PaCO2 increased in both groups, yet to a much larger degree in C group than A group (P<0.01); and NO, SO2, PaO2 decreased more markedly in C group (P<0.05 for NO, P<0.0001 for SO2 and PaO2). Conclusion Aminophylline has significant anti-hypoxia and anti-oxidation effects at high altitude. | Bo Yang Guang-yi Wang Bin Chen Rong-bin Qin Si Lang Zha Xi Lian Chen | 2007 | Chinese Medical Sciences Journal2007，22，1： | 8 |
| 2 | SOX4 contributes to TGF-β-induced epithelialemesenchymal transition and stem cell characteristics of gastric cancer cells显示文摘SOX4 is highly expressed in gastric cancer(GC)and is associated with tumor grade,metastasis and prognosis,however the mechanism is not clear.We report herein that SOX4 was upregulated and overexpression of SOX4 was associated with increased expression of the markers of Epithelialemesenchymal transition(EMT)and stemness in clinic patient samples.In vitro,overexpression of SOX4 promoted the invasion as showed by Transwell assay and stemness of GC cells as assessed by sphere formation assay,which was suppressed by silencing SOX4 with shRNA.Further studies showed that SOX4 up-regulated the expression of EMT transcription factors Twist1,snail1 and zeb1 and stemness transcription factors SOX2 and OCT4,and promoted the nuclear translocation of β-catenin.Moreover,we revealed that TGF-β treatment significantly up-regulated the expression of SOX4 and silencing SOX4 reversed TGF-β induced invasion and sphere formation ability of GC cells.Finally,we showed that SOX4 promoted the lung metastasis and tumor formation ability of gastric cancer cells in nude mice.Our results suggest that SOX4 is a target TGF-β signaling and mediates TGF-β-induced EMT and stem cell characteristics of GC cells,revealing a novel role of TGF-β/SOX4 axis in the regulation of malignant behavior of GC. | Xudong Peng Guangyi Liu Hongxia Peng Anqi Chen Lang Zha Ziwei Wang | 2018 | Genes & Diseases2018，5，1： | 4 |
| 3 | Large-scale multiferroic complex oxide epitaxy with magnetically switched polarization enabled by solution processing显示文摘Complex oxides with tunable structures have many fascinating properties,though high-quality complex oxide epitaxy with precisely controlled composition is still out of reach.Here we have successfully developed solution-based single-crystalline epitaxy for multiferroic(1-x)BiTi(1-y)/2FeyMg(1-y)/2O3–(x)CaTiO3(BTFM–CTO)solid solution in large area,confirming its ferroelectricity at the atomic scale with strong spontaneous polarization.Careful compositional tuning leads to a bulk magnetization of 0.07±0.035μB/Fe at room temperature,enabling magnetically induced polarization switching exhibiting a large magnetoelectric coefficient of 2.7–3.0×10^-7 s/m.This work demonstrates the great potential of solution processing in large-scale complex oxide epitaxy and establishes novel room-temperature magnetoelectric coupling in epitaxial BTFM–CTO film,making it possible to explore a much wider space of composition,phase,and structure that can be easily scaled up for industrial applications. | Cong Liu Feng An Paria S.M.Gharavi Qinwen Lu Junkun Zha Chao Chen Liming Wang Xiaozhi Zhan Zedong Xu Yuan Zhang Ke Qu Junxiang Yao Yun Ou Zhiming Zhao Xiangli Zhong Dongwen Zhang Nagarajan Valanoor Lang Chen Tao Zhu Deyang Chen Xiaofang Zhai Peng Gao Tingting Jia Shuhong Xie Gaokuo Zhong Jiangyu Li | 2020 | National Science Review2020，7，1： | 2 |

| 14 | Transcriptomic analysis reveals the promotion of lymph node metastasis by Helicobacter pylori infection via upregulating chemokine (C-X-C motif) receptor 2 expression in gastric carcinoma显示文摘Gastric carcinoma (GC) progression is mainly caused by local aggression and lymph node metastasis. However, some patients with early T-stage disease have lymph node metastasis, whereas some patients with late T-stage disease do not have lymph node metastasis, which indicates that invasion and metastasis are not always sequential in some GC patients. In the present study, the data of 101 GC cases were acquired from TCGA and divided into T-late-N-negative and T-early-N-positive groups according to pathological stages. A total of 338 genes were identified as differential genes between the T-late-N-negative and T-early-N-positive groups. GSEA showed that epithelial cell signaling in the Helicobacter pylori (HP ) infection pathway was enriched in the T-early-N-positive group. MB staining indicated that the HP infection rate was 63% (39/62) in N-positive patients compared to 42% (16/38) in N-negative patients. To investigate the potential mechanism, we focused on the gene chemokine (C-X-C motif) receptor 2 (CXCR2), which was not only clustered in the gene set of epithelial cells signaling in the HP infection pathway but also significantly upregulated in T-early-N-positive GC by the analysis of the different genes based on the TCGA dataset. A meta-analysis showed that CXCR2 expression was positively correlated with N-stage but not with T-stage in GC. This study indicated that invasion and metastasis could be independent processes driven by different molecular mechanisms in some GC patients. HP infection was a potential factor that promoted lymph node metastasis by upregulating CXCR2 expression. | Lang Zha Xiong Guo Xiaolong Liang Yuedong Chen Deyong Gan Wenwen Li Ziwei Wang Hongyu Zhang | 2023 | Genes & Diseases2023，10，6： | 0 |
| 15 | Glucose-responsive,antioxidative HA-PBA-FA/EN106 hydrogel enhanced diabetic wound healing through modulation of FEM1b-FNIP1 axis and promoting angiogenesis显示文摘The diabetic wounds remain to be unsettled clinically,with chronic wounds characterized by drug-resistant bacterial infections,compromised angiogenesis and oxidative damage to the microenvironment.To ameliorate oxidative stress and applying antioxidant treatment in the wound site,we explore the function of folliculininteracting protein 1(FNIP1),a mitochondrial gatekeeper protein works to alter mitochondrial morphology,reduce oxidative phosphorylation and protect cells from unwarranted ROS accumulation.And our in vitro experiments showed the effects of FNIP1 in ameliorating oxidative stress and rescued impaired angiogenesis of HUVECs in high glucose environment.To realize the drug delivery and local regulation of FNIP1 in diabetic wound sites,a novel designed glucose-responsive HA-PBA-FA/EN106 hydrogel is introduced for improving diabetic wound healing.Due to the dynamic phenylboronate ester structure with a phenylboronic acid group between hyaluronic acid(HA)and phenylboronic acid(PBA),the hydrogel is able to realize a glucose-responsive release of drugs.Fulvic acid(FA)is added in the hydrogel,which not only severs as crosslinking agent but also provides antibacterial and anti-inflammatory abilities.Moreover,the release of FEM1b-FNIP1 axis inhibitor EN106 ameliorated oxidative stress and stimulated angiogenesis through FEM1b-FNIP1 axis regulation.These in vivo and in vitro results demonstrated that accelerated diabetic wounds repair with the use of the HA-PBA-FA/EN106 hydrogel,which may provide a promising strategy for chronic diabetic wound repair. | Wenqian Zhang Kangkang Zha Yuan Xiong Weixian Hu Lang Chen Ze Lin Chenyan Yu Wu Zhou Faqi Cao Hankun Hu Bobin Mi Guohui Liu | 2023 | Bioactive Materials2023，，12： | 0 |
| 16 | Role of the immune microenvironment in bone,cartilage,and soft tissue regeneration:from mechanism to therapeuticopportunity显示文摘Bone,cartilage,and soft tissue regeneration is a complex spatiotemporal process recruiting a variety of cell types,whose activity and interplay must be precisely mediated for effective healing post-injury.Although extensive strides have been made in the understanding of the immune microenvironment processes governing bone,cartilage,and soft tissue regeneration,effective clinical translation of these mechanisms remains a challenge.Regulation of the immune microenvironment is increasingly becoming a favorable target for bone,cartilage,and soft tissue regeneration;therefore,an in-depth understanding of the communication between immune cells and functional tissue cells would be valuable.Herein,we review the regulatory role of the immune microenvironment in the promotion and maintenance of stem cell states in the context of bone,cartilage,and soft tissue repair and regeneration.We discuss the roles of various immune cell subsets in bone,cartilage,and soft tissue repair and regeneration processes and introduce novel strategies,for example,biomaterial-targeting of immune cell activity,aimed at regulating healing.Understanding the mechanisms of the crosstalk between the immune microenvironment and regeneration pathways may shed light on new therapeutic opportunities for enhancing bone,cartilage,and soft tissue regeneration through regulation of the immune microenvironment. | Yuan Xiong Bo‑Bin Mi Ze Lin Yi‑Qiang Hu Le Yu Kang‑Kang Zha Adriana CPanayi Tao Yu Lang Chen Zhen‑Ping Liu Anish Patel Qian Feng Shuan‑Hu Zhou Guo‑Hui Liu | 2023 | Military Medical Research2023，10，4： | 0 |
