| 1 | Effect of temperature,salinity and irradiance on growth and photosynthesis of Ulva prolifera显示文摘Intensive Pyropia aquaculture in the coast of southwestern Yellow Sea and its subsequent waste, including disposed Ulva prolifera, was speculated to be one of the major sources for the large-scale green tide proceeding in the Yellow Sea since 2007. It was, however, unclear how the detached U. prolifera responded and resumed growing after they detached from its original habitat. In this study, we investigated the growth and photosynthetic response of the detached U. prolifera to various temperature, salinity and irradiance in the laboratory. The photosynthetic rate of the detached U. prolifera was significantly higher at moderate temperature levels(14–27°C)and high salinity(26–32), with optimum at 23°C and 32. Both low(<14°C) and highest temperature(40°C), as well as low salinity(8) had adverse effects on the photosynthesis. Compared with the other Ulva species, U. prolifera showed higher saturated irradiance and no significant photoinhibition at high irradiance, indicating the great tolerance of U. prolifera to the high irradiance. The dense branch and complex structure of floating mats could help protect the thalli and reduce photoinhibition in field. Furthermore, temperature exerted a stronger influence on the growth rate of the detached U. prolifera compared to salinity. Overall, the high growth rate of this detached U. prolifera(10.6%–16.7% d^(–1)) at a wide range of temperature(5–32°C) and salinity(14–32) implied its blooming tendency with fluctuated salinity and temperature during floating. The environmental parameters in the southwestern Yellow Sea at the beginning of green tide were coincident with the optimal conditions for the detached U. prolifera. | XIAO Jie ZHANG Xiaohong GAO Chunlei JIANG Meijie LI Ruixiang WANG Zongling LI Yan FAN Shiliang ZHANG Xuelei | 2016 | Acta Oceanologica Sinica2016，35，10： | 14 |
| 2 | Effects of Different Microbes on Fermenting Feed for Sea Cucumber(Apostichopus japonicus)显示文摘The effects of different microbes on fermenting feed for sea cucumber(Apostichopus japonicus) were compared to select the optimal fermentation strain in this study. Saccharomgces cerevisae, Candida utilis, Bacillus subtilis and Geotrichum candidum were independently added into the experimental compound feed, while only saline was mixed with the control feed. The fermentation treatments were inoculated with 10% seed solution under the condition of 25℃ and 70% water content, which lasted for 5 days to elucidate the optimal microbe strain for fermenting effect. Physicochemical indexes and sensorial characteristics were measured per day during the fermentation. The indexes included dry matter recovery(DMR), crude protein(CP), the percentage of amino acid nitrogen to total nitrogen(AA-N/t N), the percentage of ammonia nitrogen to total nitrogen(NH3-N/t N), and the ratio of fermentation strains and vibrios to the total microbes, color, smell and viscosity. The results showed that DMR, CP and AA-N/t N of the S. cerevisae group reached the highest level on day 3, but the ratio of fermentation strain was second to C. utilis group. In addition, its NH3-N/t N and the ratio of vibrios were maintained at low levels, and the sensory evaluation score including smell, color and viscosity was the highest in S. cerevisae group on day 3. Therefore, S. cerevisae could be the optimal strain for the feed fermentation for sea cucumber. This research developed a new production method of fermentation feed for sea cucumber. | JIANG Yan WANG Yingeng MAI Kangsen ZHANG Zheng LIAO Meijie RONG Xiaojun | 2015 | Journal of Ocean University of China2015，14，5： | 5 |
| 3 | Decreased miR-325-5p Contributes to Visceral Hypersensitivity Through Post-transcriptional Upregulation of CCL2 in Rat Dorsal Root Ganglia显示文摘Chronic visceral hypersensitivity is an important type of chronic pain with unknown etiology and pathophysiology. Recent studies have shown that epigenetic regulation plays an important role in the development of chronic pain conditions. However, the role of mi RNA-325-5 p in chronic visceral pain remains unknown. The present study was designed to determine the roles and mechanism of mi RNA-325-5 p in a rat model of chronic visceral pain.This model was induced by neonatal colonic inflammation(NCI). In adulthood, NCI led to a significant reduction in the expression of mi RNA-325-5 p in colon-related dorsal root ganglia(DRGs), starting to decrease at the age of4 weeks and being maintained to 8 weeks. Intrathecal administration of mi RNA-325-5 p agomir significantly enhanced the colorectal distention(CRD) threshold in a time-dependent manner. NCI also markedly increased the expression of CCL2(C-C motif chemokine ligand 2) in colon-related DRGs at the m RNA and protein levels relative to age-matched control rats. The expression of CXCL12, IL33, SFRS7, and LGI1 was not significantlyaltered in NCI rats. CCL2 was co-expressed in Neu Npositive DRG neurons but not in glutamine synthetasepositive glial cells. Furthermore, CCL2 was mainly expressed in isolectin B4-binding-and calcitonin generelated peptide-positive DRG neurons but in few NF-200-positive cells. More importantly, CCL2 was expressed in mi R-325-5 p-positive DRG neurons. Intrathecal injection of mi RNA-325-5 p agomir remarkably reduced the upregulation of CCL2 in NCI rats. Administration of Bindarit, an inhibitor of CCL2, markedly raised the CRD threshold in NCI rats in a dose-and time-dependent manner. These data suggest that NCI suppresses mi RNA-325-5 p expression and enhances CCL2 expression, thus contributing to visceral hypersensitivity in adult rats. | Rui Wu Ping-An Zhang Xuelian Liu Yuan Zhou Meijie Xu Xinghong Jiang Jun Yan Guang-Yin Xu | 2019 | Neuroscience Bulletin2019，35，5： | 4 |
| 4 | Source of propagules of the fouling green macroalgae in the Subei Shoal,China显示文摘Since 2007,large-scale green tides dominated by Ulva prolifera consecutively bloomed in the Yellow Sea and caused great economic losses.The fouling U.prolifera on the Pyropia yezoensis aquaculture rafts in the Subei Shoal was regarded as the major source of the floating biomass.However,it was still unclear about the seed source of fouling green macroalgae attached on the rafts.In this study,the field surveys and the indoor experiments were conducted to reveal the source of propagules of the fouling green macroalgae on the rafts and to study the anti-fouling material for P.yezoensis aquaculture rafts which could possibly be a feasible strategy to control the green tides in the Yellow Sea.The results showed that(1) micro-propagules of several green macroalgal species,including U.prolifera,U.linza,U.compressa,U.flexuosa,and Blidingia sp.coexisted in the waters and sediments in the Subei Shoal and their proportion remarkably changed over time;(2) the bamboo poles with peeling treatment could significantly reduce the amount of U.prolifera micro-propagules attached.This study confirmed that the micro-propagules distributed in the Subei Shoal area were the precursors of the green tides,and provided a feasible method to control the Yellow Sea large-scale green tides at the beginning. | SONG Wei JIANG Meijie WANG Zongling WANG Hongping ZHANG Xuelei FU Mingzhu | 2018 | Acta Oceanologica Sinica2018，37，4： | 3 |

| 6 | Colon hydrotherapy plus Traditional Chinese Medicine to treat non-alcoholic fatty liver disease:a pilot study显示文摘OBJECTIVE: To demonstrate the potential to treat non-alcoholic fatty liver disease(NAFLD) with colon hydrotherapy(CHT) plus Traditional Chinese Medicine(TCM).METHODS: A total of 20 patients were enrolled into the study and received CHT with TCM for 2 weeks.Body mass index(BMI) and levels of serum triglycerides(TG) and total cholesterol(TC) were compared between pre-treatment and post-treatment.RESULTS: Two-week treatment with CHT plus TCM significantly lowered BMI and reduced blood lipids.BMI decreased from 29.5 ± 4.3 to 25.4 ± 1.0, while mean TG levels decreased by 0.70 mmol/L on average from baseline and mean TC levels decreased by0.37 mmol/L. Forty-five percent of patients exhibited TC decreasing by more than 10% from baseline and25%ofpatientsexhibited TCdecreasingbymore than 20%. Sixty percent of patients exhibited TG decreasing by more than 20% and 20% of patients exhibited TG decreasing by more than 40%. However,high-density and low-density lipoprotein cholester-ol levels did not change significantly after intervention. No serious adverse events were reported.CONCLUSION: Our findings suggest that CHT plus TCM to treat NAFLD is promising and it might be a new treatment strategy for management of NAFLD. | Xiao Huanming Jiang Junmin Xie Yubao Shi Meijie Tian Guangjun Zhao Pengtao Zhang Chaozhen Chen Huijun Xu Chanyuan Chi Xiaoling | 2017 | Journal of Traditional Chinese Medicine2017，37，3： | 1 |
| 7 | Development of a Microfluidics-Based Quantitative Real-Time PCR to Rapidly Identify Photobacterium damselae subsp.damselae with Different Pathogenicity by Detecting the Presence of mcp or dly Gene显示文摘As a marine bacterial pathogen, Photobacterium damselae subsp. damselae(PDD) is distributed in seawater worldwide. It can infect different animals as well as humans, even cause deaths. The highly conserved regions of PDD mcp gene on chromosome and dly gene on plasmid were selected as the target fragments to design the specific primers. Recombinant plasmid standard was prepared based on the primers. With GENECHECKER UF-150 qRT-PCR instrument as the platform, a fluorescence-based quantitative real-time PCR(qRT-PCR) method was established for the detection of PDD. This method can specifically detect PDD and distinguish the highly virulent strains. Additionally, the test results can be qualitatively judged by visualization, while the quantitative detection can be achieved through the standard curve calculation. The minimum limit of detection was 1.0×101 copies μL-1, and the detection time was less than 20 min. In summary, this new method has outstanding advantages, such as strong specificity, high sensitivity, and low site requirements. It is a rapid on-site detection technology for highly virulent PDD strains. | ZHANG Zheng YU Yongxiang CHEN Jing WANG Yingeng JIANG Yong LIAO Meijie RONG Xiaojun ZHANG Hao | 2021 | Journal of Ocean University of China2021，20，2： | 0 |
| 8 | The effects of 2-Bromopropane on Viability and TestosteroneProduction Ability of Rat Leydig Cells in Primary Culture显示文摘Epidemiological surveys and animal experiments have shown that 2-bromopropane induces oligozoospermia in exposed workers and inhibits spermatogensis in laborratory animals. However, themechanism by which 2-bromopropane exerts its effects is unknown. To this end, we examined the formation of testosterone by the Leydig cells and their survival of these cells in the Presence of differ-ent concentrations of 2-bromopropane in vitro. Leydig cells were isolated following vascular Perfu-sion, enzymatic dissociation and Percoll gradient centrifugation techniques. The cells were cultured in culture dishes. After 8 h, different cultures were exposed to 2-bromopropane at concentrations of 0.01 mmol/L, 0.10 mmol/L and 1.00 mmol/L. In order to stimulate Leydig cells to secrete testos-terone, human chorionic gonadotropin (hCG) was also added. Cell viability was determined using the trypan blue dye exclusion test and cell numbers were counted by hemocytometer. Testosterone secretion was detected by radioimmunoassay. The cell viability decreased after exposure to 2-bromo-propane in a dose-dependent way, but no morphological change was observed. The cell number de-creased in the 2-bromopropane-treated cultures. The secretion of testosterone did not manifest de -tectable changes in the culture treated with 0.10 mmol/L and 0.01 mmol/L of 2-bromopropane;however, it decreased significantly (P < 0. 02) in the Presence of 1.00 mmol/L. Therefore, ourresults strongly suggest that 2-bromopropane may exert its cytotoxic effects on heydig cells in vitro.We speculate that the decrease in the numbers of Leydig cells caused by 2-bromopropane was medi-ated by a feedback mechanism resulting from a lower testosterone concentration. | YANG JIAN-MING WU XIAO-YUN DING XUN-CHENG PANG BING JIANG XUE-ZHI (National Evaluation Center for the Toxicology of Fertilicy Regulating Drugs,Shanghai 200032, China) JI ZAI-SI AND SHIN KAZUO( MeiJi Institute of Health Science,Odewara 250, Japan)WU | 1999 | Biomedical and Environmental Sciences1999，12，1： | 0 |
