2Notch signaling mediated by TGF-β/Smad pathway in concanavalin A-induced liver fibrosis in rats显示文摘AIM To explore the exact interaction between Notch and transforming growth factor(TGF)-β signaling in liver fibrosis. METHODS We established a rat model of liver fibrosis induced by concanavalin A. Peripheral blood mononuclear cells(PBMCs) were isolated from the modeled rats, and cultured with γ-secretase inhibitor DAPT and TGF-β inhibitor for 24 h. The m RNA levels of Notch and TGF-β signaling were detected by quantitative real-time polymerase chain reaction. Expression of Notch and TGF-β proteins was analyzed by western blotting.RESULTS Compared to control rats, Notch and TGF-β signaling was activated in PBMCs of model rats. Administration of DAPT and TGF-β inhibitor suppressed Notch and TGF-β signal transducer in PBMCs of model rats. DAPT reduced m RNA and protein expression of TGF-β signaling, such as TGF-β1 and Smad3. TGF-β inhibitor also downregulated Notch1, Hes1 and Hes5, and m RNA and protein expression of the Notch signaling pathway.CONCLUSION Notch and TGF-β signaling play a role in liver fibrosis. TGF-β signaling upregulates Notch signaling, which promotes TGF-β signaling.Yi Wang Ruo-Wu Shen Bing Han Zhen Li Le Xiong Feng-Yu Zhang Bei-Bei Cong Bei Zhang 2017World Journal of Gastroenterology2017,23,13:25
3In vitro differentiation of adipose-derived stem cells and bone marrow-derived stromal stem cells into neuronal-like cells显示文摘Adipose-derived stem cells and bone marrow-derived stromal stem cells were co-cultured with untreated or Aβ1-40-treated PC12 cells, or grown in supernatant derived from untreated or Aβ1-40-treated PC12 cells. Analysis by western blot and quantitative real-time PCR showed that protein levels of Nanog, Oct4, and Sox2, and mRNA levels of miR/125a/3p were decreased, while expression of insulin-like growth factor-2 and neuron specific enolase was increased. In comparison, the generation of neuron specific enolase-positive cells was most successful when adipose-derived stem cells were co-cultured with Aβ1-40-treated PC12 cells. Our results demonstrate that adipose-derived stem cells and bone marrow-derived stromal stem cells exhibit trends of neuronal-like cell differentiation after co-culture with Aβ1-40-treated PC12 cells. This process may relate to a downregulation of miR-125a-3p mRNA expression and increased levels of insulin-like growth factor-2 expression.Jin Zhou Guoping Tian Jing'e Wang Xuefeng Cong Xingkai Wu Siyang Zhang Li Li Bing Xu Feng Zhu Xuedan Luo Jian Han Fengjie Hu 2011Neural Regeneration Research2011,6,19:21
4T cell–associated immunoregulation and antiviral effect of oxymatrine in hydrodynamic injection HBV mouse model显示文摘Although oxymatrine(OMT) has been shown to directly inhibit the replication of hepatitis B virus(HBV) in vitro, limited research has been done with this drug in vivo. In the present study, the antiviral effect of OMT was investigated in an immunocompetent mouse model of chronic HBV infection.The infection was achieved by tail vein injection of a large volume of DNA solution. OMT(2.2, 6.7 and20 mg/kg) was administered by daily intraperitoneal injection for 6 weeks. The efficacy of OMT was evaluated by the levels of HBV DNA, hepatitis B surface antigen(HBs Ag), hepatitis B e antigen(HBe Ag)and hepatitis B core antigen(HBc Ag). The immunoregulatory activity of OMT was evaluated by serum ELISA and flow cytometry. Results shows that OMT at 20 mg/kg inhibited HBV replication, and it was more efficient than entecavir(ETV) in the elimination of serum HBs Ag and intrahepatic HBc Ag. Inaddition, OMT accelerated the production of interferon-γ(IFN-γ) in a dose-dependent manner in CD4^+T cells. Our findings demonstrate the beneficial effects of OMT on the enhancement of immunological function and in the control of HBV antigens. The findings suggest this drug to be a good antiviral therapeutic candidate for the treatment of HBV infection.Xiuxiu Sang Ruilin Wang Yanzhong Han Cong’en Zhang Honghui Shen Zhirui Yang Yin Xiong Huimin Liu Shijing Liu Ruisheng Li Ruichuang Yang Jiabo Wang Xuejun Wang Zhaofang Bai Xiaohe Xiao 2017Acta Pharmaceutica Sinica B2017,7,3:20
5A drug-eluting Balloon for the trEatment of coronarY bifurcatiON lesions in the side branch:a prospective multicenter ranDomized (BEYOND)clinical trial in China显示文摘Background:Treatment of coronary bifurcation lesions remains challenging;a simple strategy has been preferred as of late,but the disadvantage is ostium stenosis or even occlusion of the side branch(SB).Only a few single-center studies investigating the combination of a drug-eluting stent in the main branch followed by a drug-eluting balloon in the SB have been reported.This prospective,multicenter,randomized study aimed to investigate the safety and efficacy of a paclitaxel-eluting balloon(PEB)compared with regular balloon angioplasty(BA)in the treatment of non-left main coronary artery bifurcation lesions.Methods:Between December 2014 and November 2015,a total of 222 consecutive patients with bifurcation lesions were enrolled in this study at ten Chinese centers.Patients were randomly allocated at a 1:1 ratio to a PEB group(n=113)and a BA group(n=109).The primary efficacy endpoint was angiographic target lesion stenosis at 9 months.Secondary efficacy and safety endpoints included target lesion revascularization,target vessel revascularization,target lesion failure,major adverse cardiac and cerebral events(MACCEs),all-cause death,cardiac death,non-fatal myocardial infarction,and thrombosis in target lesions.The main analyses performed in this clinical trial included case shedding analysis,base-value equilibrium analysis,effectiveness analysis,and safety analysis.SAS version 9.4 was used for the statistical analyses.Results:At the 9-month angiographic follow-up,the difference in the primary efficacy endpoint of target lesion stenosis between the PEB(28.7%±18.7%)and BA groups(40.0%±19.0%)was-11.3%(95%confidence interval:-16.3%to-6.3%,Psuperiority<0.0001)in the intention-to-treat analysis,and similar results were recorded in the per-protocol analysis,demonstrating the superiority of PEB to BA.Late lumen loss was significantly lower in the PEB group than in the BA group(-0.06±0.32 vs.0.18±0.34 mm,P<0.0001).For intention-to-treat,there were no significant differences between PEB and BA in the 9-month percentages of MACCEs(0.9%vs.3.7%,P=0.16)or non-fatal myocardial infarctions(0 vs.0.9%,P=0.49).There were no clinical events of target lesion revascularization,target vessel revascularization,target lesion failure,all-cause death,cardiac death or target lesion thrombosis in either group.Conclusions:In de novo non-left main coronary artery bifurcations treated with provisional T stenting,SB dilation with the PEB group demonstrated better angiographic results than treatment with regular BA at the 9-month follow-up in terms of reduced target lesion stenosis.Trial registration:ClinicalTrials.gov,NCT02325817;http://gffzzd3f38a9638994581s5cfq6cxp96qk6cpk.ffgz.tsg.suse.edu.cn.Quan-Min Jing Xin Zhao Ya-Ling Han Ling-Ling Gao Yang Zheng Zhan-Quan Li Ping Yang Hong-Liang Cong Chuan-Yu Gao Tie-Min Jiang Hui Li Jun-Xia Li Dong-Mei Wang Geng Wang Zhan-Chun Cong Zhong Zhang 2020Chinese Medical Journal2020,,8:17
6Oral berberine improves brain dopa/dopamine levels to ameliorate Parkinson’s disease by regulating gut microbiota显示文摘The phenylalanine-tyrosine-dopa-dopamine pathway provides dopamine to the brain.Iin this process,tyrosine hydroxylase(TH)isthe rate-limiting enzyme that hydroxylates tyrosine and generates levodopa(L-dopa)with tetranydrobiopterin(BH_(4))as a coenzyme.Here,we show that oral berberine(BBR)might supply H^(·) through dihydroberberine(reduced BBR produced by bacterial nitroreductase)and promote the production of BHl from dihydrobiopterin;the increased BH,enhances TH activity,which accelerates the production of L-dopa by the gut bacteria.Oral BBR acts in a way similar to vitamins.The L-dopa produced by theintestinal bacteria enters the brain through the circulation and is transformed to dopamine.To verify the gut-brain dialog activatedby BBR's effect,Enterococcus foecalis or Enterococcus faecium was transplanted into Parkinson's disease(PD)mice.The bacteriasignificantly increased brain dopamine and ameliorated PD manifestation in mice;additionally,combination of BBR with bacteriashowed better therapeutic effect than that with bacteria alone.Moreover,2,4,6-trimethy-pyranylium tetrafluoroborate(TMP-TFB)-derivatized matrix-assisted laser desorption mass spectrometry(MALDI-MS)imaging of dopamine identihed elevated striataldopamine levels in mouse brains with oral Enterococcus,and BBR strengthened the imaging intensity of brain dopamine.Theseresults demonstrated that BBR was an agonist of TH in Enterococcus and could lead to the production of L-dopa in the gut.Furthermore,a study of 28 patients with hyperlipidemia conhrmed that oral BBR increased bloodfecal L-dopa by the intestinalbacteria.Hence,BBR might improve the brain function by upregulating the biosynthesis of-dopa in the gut microbiota through avitamin-like effect.Yan Wang Qian Tong Shu-Rong Ma Zhen-Xiong Zhao Li-Bin Pan Lin Cong Pei Han Ran Peng Hang Yu Yuan Lin Tian-Le Gao Jia-Wen Shou Xiao-Yang Li Xian-Feng Zhang Zheng-Wei Zhang Jie Fu Bao-Ying Wen Jin-Bo Yu Xuetao Cao Jian-Dong Jiang 2021Signal Transduction and Targeted Therapy2021,6,3:16
7Establishment of a novel corneal endothelial cell line from domestic rabbit,Oryctolagus curiculus显示文摘To develop a rabbit corneal endothelial (RCE) cell line, in vitro culture of RCE cells was initiated from Oryctolagus curiculus corneas and a novel RCE cell line was established in this study. To initiate the primary culture of RCE cells, corneas from rabbit eyes were sliced and attached into glutin-coated wells with endothelial cell surface down. After being cultured at a time-gradient interval from 48 to 6 h, the corneal slices were detached and reattached into new wells, respectively. Cells in the wells containing only a pure population of RCE cells were collected and cultured in 20% FBS-DMEM/F12 medium con- taining chondroitin sulfate, ocular extract, epidermal growth factor (EGF), basic fibroblast growth factor (bFGF), carboxymethyl-chitosan, N-acetylglucosamine hydrochloride, glucosamine hydrochloride, culture medium of rabbit corneal stromal cells and oxidation-degradation products of chondroitin sul- fate at 37℃, 5% CO2. The cultured RCE cells, in quadrangle and polygonal shapes, proliferated to con- fluence 3 weeks later. During the subsequent subculture, the shape of RCE cells changed gradually from polygonal to more fibroblastic. A novel RCE cell line, growing at a steady rate, with a population doubling time of 53.8 h, has been established and subcultured to passage 67. Chromosome analysis showed that the RCE cells exhibited chromosomal aneuploidy with the modal chromosome number of 44. The results of immuno-cytochemical staining with neuron specific enolase (NSE) confirmed that the RCE cells were in neuroectodermal origin. Combined with the results of vascular endothelial growth factor (VEGF) treatment and endothelial cell morphology recovery, it can be concluded that the cell line established here is an RCE cell line. This RCE cell line may serve as a useful tool in theoretical re- searches of mammalian corneal endothelial cells, and may also have potential application in artificial corneal endothelium development.FAN TingJun, ZHAO Jun, FU YongFeng, CONG RiShan, GUO RuiChao, LIU WanShun, HAN BaoQin, YU QiuTao & WANG JingCollege of Marine Life Sciences, Division of Life Science and Technology, Ocean University of China, Qingdao 266003, China 2007Science China(Life Sciences)2007,50,2:15
8All-optical active THz metasurfaces for ultrafast polarization switching and dynamic beam splitting显示文摘Miniaturized ultrafast switchable optical components with an extremely compact size and a high-speed response will be the core of next-generation all-optical devices instead of traditional integrated circuits,which are approaching the bottleneck of Moore’s Law.Metasurfaces have emerged as fascinating subwavelength flat optical components and devices for light focusing and holography applications.However,these devices exhibit a severe limitation due to their natural passive response.Here we introduce an active hybrid metasurface integrated with patterned semiconductor inclusions for all-optical active control of terahertz waves.Ultrafast modulation of polarization states and the beam splitting ratio are experimentally demonstrated on a time scale of 667 ps.This scheme of hybrid metasurfaces could also be extended to the design of various free-space all-optical active devices,such as varifocal planar lenses,switchable vector beam generators,and components for holography in ultrafast imaging,display,and high-fidelity terahertz wireless communication systems.Longqing Cong Yogesh Kumar Srivastava Huifang Zhang Xueqian Zhang Jiaguang Han Ranjan Singh 2018Light(Science & Applications)2018,7,1:15

10Dynamic Changes in the Wetland Landscape Pattern of the Yellow River Delta from 1976 to 2016 Based on Satellite Data显示文摘The Yellow River Delta wetland is the youngest wetland ecosystem in China's warm temperate zone. To better understand how its landscape pattern has changed over time and the underlying factors responsible, this study analyzed the dynamic changes of wetlands using five Landsat series of images, namely MSS(Mulri Spectral Scanner), TM(Thematic Mapper), and OLI(Operational Land Imager) sensors in 1976, 1986, 1996, 2006, and 2016. Object-oriented classification and the combination of spatial and spectral features and both the Normalized Difference Vegetation Index(NDVI) and Normalized Difference Water Index(NDWI), as well as brightness characteristic indices, were used to classify the images in eCognition software. Landscape pattern changes in the Yellow River Delta over the past 40 years were then delineated using transition matrix and landscape index methods. Results show that: 1) from1976 to 2016, the total area of wetlands in the study area decreased from 2594.76 to 2491.79 km^2, while that of natural wetlands decreased by 954.03 km^2 whereas human-made wetlands increased by 851.06 km^2. 2) The transformation of natural wetlands was extensive: 31.34% of those covered by Suaeda heteropteras were transformed into reservoirs and ponds, and 24.71% with Phragmites australis coverage were transformed into dry farmland. Some human-made wetlands were transformed into non-wetlands types: 1.55% of reservoirs and ponds became construction land, and likewise 21.27% were transformed into dry farmland. 3) From 1976 to 2016, as the intensity of human activities increased, the number of landscape types in the study area continuously increased. Patches were scattered and more fragmented. The whole landscape became more complex. In short, over the past 40 years, the wetlands of the Yellow River Delta have been degraded, with the area of natural wetlands substantially reduced. Human activities were the dominant forces driving these changes in the Yellow River Delta.CONG Pifu CHEN Kexin QU Limei HAN Jianbo 2019Chinese Geographical Science2019,29,3:12

12Biosynthesis of Triacylglycerol Molecules with a Tailored PUFA Profile in Industrial Microalgae显示文摘The composition of polyun saturated fatty acids (PUFAs) in triacylglycerols (TAGs) is key to health ben efits and for oil applications, yet the underlying genetic mechanism remains poorly understood. In this study, by in si Iico, ex vivo, and in vivo profili ng of type-2 diacylglycerol acyltransferases (DGAT2s) in Nannochloropsis oceanica we revealed two novel PUFA-preferring enzymes that discriminate individual PUFA species in TAG assembly, with NoDGAT2J for linoleic acid (LA) and NoDGAT2K for eicosapentaenoic acid (EPA). The LA and EPA composition of TAG molecules is mediated in vivo via the functional partitioning between NoDGAT2J and 2K, both of which are localized in the chloroplast envelope. By modulating transcript abundance of the DGAT2s, an N. oceanica strain bank was created, where proportions of LA and EPA in TAG vary by 18.7-fold (between 0.21% and 3.92% dry weight) and 34.7-fold (between 0.09% and 3.12% dry weight), respective!y. These findings lay the foundation for producing designer TAG molecules with tailored health benefits or for biofuel applications in industrial microalgae and higher-plant crops.Yi Xin Chen Shen Yiting She Hong Chen Cong Wang Li Wei Kangsup Yoon Danxiang Han Qiang Hu Jian Xu 2019Molecular Plant2019,12,4:10

14Spatial Properties of Mismatch Negativity in Patients with Disorders of Consciousness显示文摘In recent decades, event-related potentials have been used for the clinical electrophysiological assessment of patients with disorders of consciousness(DOCs). In this paper, an oddball paradigm with two types of frequencydeviant stimulus(standard stimuli were pure tones of 1000 Hz; small deviant stimuli were pure tones of 1050 Hz; large deviant stimuli were pure tones of 1200 Hz) was applied to elicit mismatch negativity(MMN) in 30 patients with DOCs diagnosed using the JFK Coma Recovery ScaleRevised(CRS-R). The results showed that the peak amplitudes of MMN elicited by both large and small deviant stimuli were significantly different from baseline.In terms of the spatial properties of MMN, a significant interaction effect between conditions(small and large deviant stimuli) and electrode nodes was centered at the frontocentral area. Furthermore, correlation coefficients were calculated between MMN amplitudes and CRS-R scores for each electrode among all participants to generate topographic maps. Meanwhile, a significant negative correlation between the MMN amplitudes elicited by large deviant stimuli and the CRS-R scores was also found at the frontocentral area. In consequence, our results combine the above spatial properties of MMN in patients with DOCs,and provide a more precise location(frontocentral area) at which to evaluate the correlation between clinical electrophysiological assessment and the level of consciousness.Xiaoyu Wang Rao Fu Xiaoyu Xia Xueling Chen Han Wu Nicole LANDi Ken Pugh Jianghong He Fengyu Cong 2018Neuroscience Bulletin2018,34,4:9
15Carbendazim sensitivity in populations of Colletotrichum gloeosporioides complex infecting strawberry and yams in Hubei Province of China显示文摘The ascomycete fungus Colletotrichum gloeosporioides is a devastating plant pathogen with a wide host range and worldwide distribution. Carbendazim has been widely used to control anthracnose caused by the C. gloeosporioides complex in China for more than 30 years and resistance to carbendazim has been reported in China. A total of 125 Colletotrichum isolates of strawberry and yam were collected from different geographical regions in Hubei Province, China. Approximately 52.8% of Colletotrichum spp. isolates showed resistance to carbendazim. The isolates tested in this study belong to four species, and the frequencies of resistant isolates differed across Colletotrichum species. Resistant isolates were found in C. siamense and C. fructicola. In contrast, all isolates of C. gloeosporioides and C. aenigma were sensitive to carbendazim. Highly carbendazim-resistant isolates harbored the E198 A mutation in the β-tubulin 2(TUB2) gene, whereas moderately carbendazim-resistant isolates harbored the F200 Y mutation in the TUB2 gene. Carbendazim-sensitive Colletotrichum isolates in this study were not genetically similar enough to form a separate cluster from resistant isolates. The result of this study emphasizes the importance of knowing which Colletotrichum sp. is present, when strategies for disease control are made.HAN Yong-chao ZENG Xiang-guo XlANG Fa-yun ZHANG Qing-hua GUO Cong CHEN Feng-ying GU Yu-chen 2018Journal of Integrative Agriculture2018,17,6:9
16Malnutrition and Quality of Life in Chinese Cancer Patients: a Clinical Study of 23,994 Subjects显示文摘Background Malnutrition is common in patients with cancer,and can negatively impact their quality of life(QoL)and even survival.However,there is currently no large data available on the prevalence of malnutrition in Chinese cancer patients.This study evaluated the prevalence of malnutrition and the QoL of Chinese patients with locoregional,recurrent or metastatic cancer.Methods We conducted a nationwide observational,multi-center,hospital-based cross-sectional study within the Chinese Society of Nutritional Oncology(CSNO)Network.All of the patients were diagnosed with one of the following 18 different types of malignant tumors:lung cancer,gastric cancer,liver cancer,colorectal cancer,breast cancer,esophageal cancer,cervical cancer,endometrial cancer,nasopharyngeal carcinoma,malignant lymphoma,leukemia,pancreatic cancer,ovarian cancer,prostate cancer,bladder cancer,brain cancer,biliary tract malignant tumors or gastrointestinal stromal tumors.These patients were enrolled from 72 hospitals located in different regions of China.The patients’nutritional status was evaluated based on the body mass index(BMI),loss of bodyweight,laboratory measurements and patient generated-subjective global assessment(PG-SGA)scores.The cancer patients’physical status and QoL were assessed by the Karnofsky Performance Status(KPS)questionnaire and the European Organization for Research and Treatment of Cancer(EORTC)QLQ-C30 questionnaire,respectively.Results From December 2013 to April 2016,23,994 patients hospitalized for cancer treatment(such as surgery,chemotherapy or radiotherapy)were enrolled in the study.The patients included 12,494(52.9%)males and 11,124(47.1%)females.The mean age was 55.8±13.7 years.The proportions of patients in cancer stagesⅠ,Ⅱ,Ⅲ,Ⅳand uncertain were 11.5%,20.3%,27.5%,30.2%and 10.5%,respectively.Among the 23,994 inpatients,the proportions of patients who were underweight(BMI<18.5 kg/m2),normal(18.5 kg/m2Hong Xia Xu Chun Hua Song Zhen Ming Fu Chang Wang Zeng Qing Guo Yuan Lin Ying Ying Shi Wen Hu Yi Ba Su Yi Li Zeng Ning Li Kun Hua Wang Jing Wu Ying He Jia Jun Yang Cong Hua Xie Fu Xiang Zhou Xin Xia Song Gong Yan Chen Wen Jun Ma Su Xia Luo Zi Hua Chen Ming Hua Cong Hu Ma Chun Ling Zhou Wei Wang Qi Luo Yong Mei Shi Yu Mei Qi Hai Ping Jiang Wen Xian Guan Jun Qiang Chen Jia Xin Chen Yu Fang Lan Zhou Yong Dong Feng Rong Shao Tan Tao Li Jun Wen Ou Qing Chuan Zhao Jian Xiong Wu Min Weng Qing Hua Yao Jiu Wei Cui Wei Li Han Ping Shi the Investigation on Nutrition Status and Clinical Outcome of Common Cancers(INSCOC)Group 2021Journal of Nutritional Oncology2021,6,1:8
17Curcumenol triggered ferroptosis in lung cancer cells via lncRNA H19/miR-19b-3p/FTH1 axis显示文摘Curcumenol,an effective ingredient of Wenyujin,has been reported that exerted its antitumor potential in a few cancer types.However,the effect and molecular mechanism of curcumenol in lung cancer are largely unknown.Here,we found that curcumenol induced cell death and suppressed cell proliferation in lung cancer cells.Next,we demonstrated that ferroptosis was the predominant method that contributed to curcumenol-induced cell death of lung cancer in vitro and vivo for the first time.Subsequently,using RNA sequencing,we found that the long non-coding RNA H19(lncRNA H19)was significantly downregulated in lung cancer cells treated with curcumenol,when compared to untreated controls.Overexpression of lncRNA H19 eliminated the anticancer effect of curcumenol,while lncRNA H19 knockdown promoted ferroptosis induced by curcumenol treatment.Mechanistically,we showed that lncRNA H19 functioned as a competing endogenous RNA to bind to miR-19b-3p,thereby enhanced the transcription activity of its endogenous target,ferritin heavy chain 1(FTH1),a marker of ferroptosis.In conclusion,our data show that the natural product curcumenol exerted its antitumor effects on lung cancer by triggering ferroptosis,and the lncRNA H19/miR-19b-3p/FTH1 axis plays an essential role in curcumenol-induced ferroptotic cell death.Therefore,our findings will hopefully provide a valuable drug for treating lung cancer patients.Ruonan Zhang Ting Pan Yu Xiang Mingming Zhang Han Xie Zimao Liang Bi Chen Cong Xu Jing Wang Xingxing Huang Qianru Zhu Ziming Zhao Quan Gao Chengyong Wen Wencheng Liu Weirui Ma Jiao Feng Xueni Sun Ting Duan Elaine Lai-Han Leung Tian Xie Qibiao Wu Xinbing Sui 2022Bioactive Materials2022,7,7:8
18Influence of Temperature and Salinity on Germination of Eelgrass (Zostera marina L.) Seeds显示文摘Seagrass restoration as part of ocean ecosystem protection has been launched for many years all over the world, but intensive research on this subject in China has just begun in recent years. Seed broadcasting has been widely accepted as the most potentially useful method for seagrass restoration over large areas. We examined the influence of key environmental factors on seed germination to help promote eelgrass bed restoration. Under anoxic conditions, the influence of temperature and salinity on the germination rate of eelgrass (Zostera marina L.) seeds was examined at different combinations of four temperatures (4, 9, 14, and 24℃) and nine salinities (5 to 45, increment of 5). The effect of significant interaction of temperature and salinity on germination rate was observed (ANOVA) (P<0.001). The highest germination rate (83.3 ± 3.5)% was reached in 8 weeks at 14℃ and salinity 5. Higher temperature significantly increased the germination rate at salinity 5 (P<0.001) during the whole observation period except for 24℃, while lower salinity significantly increased the germination rate at 14℃ (P<0.001). Although significant interaction was found between temperature and salinity (P<0.001), the influence of salinity was stronger than that of temperature for the germination of eelgrass seeds.
