| 2 | Effects of electroacupuncture at Guanyuan(CV 4)or Sanyinjiao(SP 6)on hypothalamus-pituitary-ovary axis and spatial learning and memory in female SAMP8 mice显示文摘OBJECTIVE: To investigate the effects of electroacupuncture(EA) at the Guanyuan(CV 4) or Sanyinjiao(SP 6) acupoints on the hypothalamus-pituitary-ovary(HPO) axis and spatial learning and memory in female mice.METHODS: Nine-month-old female mice with senescence-accelerated mouse prone 8(SAMP8)were divided into three groups: the disease model,EA-Guanyuan and EA-Sanyinjiao groups. Concurrently, 9-month old female mice with senescence-accelerated mouse resistance 1(SAMR1)were set as the control model group. The two treatment groups were given the same pattern of EA stimulation. Gonadotropin-releasing hormone, luteinizing hormone, follicle-stimulating hormone(FSH) and Serum estradiol levels in the Hypothalamus-pituitary-ovary axis were assessed by enzyme-linked immunosorbent assay to determinethe HPO axis function level. Spatial learning and memory were assessed by the Morris Water Maze(MWM) test.RESULTS:(a) HPO axis: compared with the control model group, the disease model group displayed a decrease in E2 levels(P < 0.01), and an increase in Gn RH, LH and FSH levels(P < 0.01). E2 levels were increased in EA treatment groups compared with the disease model group(P < 0.05). In contrast,Gn RH and LH and FSH levels were reduced(P <0.05). EA-Sanyinjiao group was superior than EA-Guanyuan group on increasing E2 and declining Gn RH levels(P < 0.01).(b) The MWM test demonstrated that the response latency in the EA-Sanyinjiao treatment group declined from day 2 to day5 compared with the disease model group(P <0.05), whereas the EA-Guanyuan treatment group showed no significant difference.CONCLUSION: EA can regulate hormone(E2, FSH,LH, Gn RH) levels in the HPO axis and the spatial learning and memory ability in female SAMP8 mice. Moreover, this effect may have been more pronounced in the EA-Sanyinjiao group than the EA-Guanyuan group. The underlying mechanism of the EA-induced changes may be related to gonadal hormone shifts in the HPO axis, followed by an improvement in spatial learning and memory. | Wang Jing Cheng Kai Qin Zhuo Wang Yanping Zhai Lijing You Min Wu Juanjiao | 2017 | Journal of Traditional Chinese Medicine2017，37，1： | 8 |
| 3 | The input/removal rates of size-fractionated ^210Po in the Jiulongjiang estuary and its implications显示文摘The geochemical behaviors of dissolved (<0.4 mm), low molecular weight (<10 kDa) and colloidal (10 kDa- 0.4 mm) 210Po in surface waters from the Jiulongjiang estuary were examined and the input/removal rates of different 210Po species were estimated. Both dissolved and low molecular weight 210Po were considerably removed during estuarine mixing. However, colloidal 210Po was removed only at low salinity regions (S <15) but had input behavior at high salin-ity surface waters (S >15). The input/removal rates of three species indicate that 210Po was removed rapidly in the Jiu-longjiang estuary. The discrepancy of input/removal rates between 210Po species suggests different geochemical be-havior and a dynamic transformation between 210Po species. Low molecular weight 210Po may be more appropriate for characterizing the 210Po behavior in estuary zone than the traditional dissolved 210Po. | YANG Weifeng, CHEN Min, HUANG Yipu, QIU Yusheng, ZHANG Lei, XING Na & LI Yanping Department of Oceanography, Xiamen University, Xiamen 361005, China Correspondence should be addressed to Huang Yipu (e-mail: yphuang@ jingxina.xmu.edu.cn) | 2003 | Chinese Science Bulletin2003，48，21： | 8 |
| 4 | Regional estimates of POC export flux derived from thorium-234 in the western Arctic Ocean显示文摘In order to elucidate the regional export variation of particulate organic carbon in the western Arctic Ocean, samples vertically integrated between 0 and 100 m depth or between 0 and 30 m/40 m depth were collected for total 234Th measurements and those from 30 m/40 m or 100 m depth were collected for particulate 234Th measurements during the Second Chinese Arctic Expedition in July-September 2003. The removal fluxes and residence time of 234Th in the upper water column were calculated by using irreversible steady-state scavenging model. The results showed that, total 234Th was deficit relative to its parent 238U in the western Arctic Ocean except in the western Chukchi shelf and the slope regions around 160°W, indicating that scavenging and removal processes play an important role in element biogeochemical cycle in the Arctic Ocean. In the western Chukchi shelf and the slope regions around 160°W, total 234Th was excess relative to 238U, ascribing to the horizontal input of 234Th adsorbed by ice-rafted sediments. Thorium-234 removal fluxes decreased from the shelf to the deep ocean, while the residence time of 234Th increased from shelf to offshore, demonstrating that particle scavenging and removal processes are more active in the shelf regions. The estimated POC export fluxes from 40 m in the shelf regions and from 100 m in the slope and deep ocean varied between 1.6 and 27.5 mmol/(m2·d), and between 1.8 and 14.4 mmol/(m2·d), respectively. The averaged POC export fluxes over the entire water column decreased from the shelf to the deep ocean, indicating that the Chukchi shelf is an important region for organic carbon sequestration. The high ThE ratios (ratio of POC export flux derived from 234Th/238U disequilibria to primary production) in the western Arctic Ocean suggested that the biological pump runs actively in high-latitudes. | MA Qiang CHEN Min QIU Yusheng LI Yanping | 2005 | Acta Oceanologica Sinica2005，24，6： | 7 |
| 5 | ^(226)Ra evidence for the ecosystem shift over the past 40 years in the North Pacific Subtropical Gyre显示文摘Surface seawater was collected for ^(226)Ra measurement in the North Pacific Subtropical Gyre from July to October, 1999 and October to December, 2003. Combined with the historical data reported for this sea area, a declined trend of surface ^(226)Ra concentrations was observed since 1960s, indicating the ecosystem shift in response to global warming. On one side, the enhanced stratification of the upper water column resulting from global warming reduced the ^(226)Ra input from the depth, on the other, the temporal increase of biological production resulting from the climate-related ecosystem structure change strengthened the ^(226)Ra removal from the surface ocean. Both the physical and biological processes resulted in the decrease of surface ^(226)Ra concentrations in the North Pacific Subtropical Gyre. The temporal trend of surface ^(226)Ra concentrations was consistent with the trends of chlorophyll a, silicate, phosphate and primary production previously reported. This study provided ^(226)Ra evidence for the ecosystem shift under global change. | YANG JunHong CHEN Min QIU YuSheng LI YanPing MA Qiang LUE E ZHANG Run HUANG YiPu | 2007 | Chinese Science Bulletin2007，52，6： | 5 |
| 6 | Contrasting patterns of river runoff and sea-ice melted water in the Canada Basin显示文摘The fractions of river runoff and sea-ice melted water in the Canada Basin in summer 2003 were determined by the salinity-18O system. The fraction of river runoff(fR) was high in the upper 50 m of the water column and decreased with depth and latitude. The signals of the river runoff were confined to water depths above 200 m. The total amount of river runoff in the Canada Basin was higher than that in other arctic seas, indicating that the Canada Basin is a main storage region for river runoff. The penetration depth of the sea-ice melted water was less than 50 m to the south of 78°N, while it was about 150 m to the north of 78°N. The total amount of sea-ice melted water was much higher to the north of 78°N than to the south of 78°N, indicating the sea-ice melted waters accumulated on the ice edge. The abundant sea-ice melted water on the ice edge was attributed to the earlier melted water in the southern Canada Basin and transported by the Beaufort Gyre or the reinforced melting of sea ice by solar radiation in the polynya. | TONG Jinlu CHEN Min QIU Yusheng LI Yanping CAO Jianping | 2014 | Acta Oceanologica Sinica2014，33，6： | 4 |
| 7 | Ultrathin nanosheets of cobalt-nickel hydroxides hetero-structure via electrodeposition and precursor adjustment with excellent performance for supercapacitor显示文摘A homogeneous better-dispersed ultrathin nanosheets(ca. 5 nm) of cobalt-nickel layered double hydroxides(LDH) supported on nickel foam scaffold was synthesized using controllable electrodeposition approach for high efficiency electrode materials of new supercapacitor. The morphology and electrochemical performances of the samples can be controlled by adjusting the precursor ratio, i.e., Ni(OAc)_2/Co(NO_3)_2 molar ratio in the electrodeposition approach. With the increase of this molar ratio, the electrochemical performances give a volcano trend. When the optimized molar ratio is 0.64/0.36, the hybrid delivered a high specific capacitance of 1587.5 F g^(-1) at a current density of 0.5 A g^(-1), with good rate capability(1155 F g^(-1) was retained even at 10 A g^(-1)) and a robust recycle stability(remaining 91.5% after 1000 cycles at 5 A g^(-1)). The good performance could be attributed to the enlarged interlayer spacing, ultrathin nanosheets and synergistic effects between Co(OH)_2 and Ni(OH)_2. Furthermore, an asymmetric supercapacitor with a high energy density of 34.5 Wh kg^(-1) at 425 W kg^(-1) and excellent cycling stability of 85.4% after 5000 charge-discharge cycles at 2 A g^(-1) was fabricated. We believe that this fantabulous new electrode material would have encouraging applications in electrochemical energy storage and a wide readership. | Min Wei Qingsong Huang Yanping Zhou Zhu Peng Wei Chu | 2018 | Journal of Energy Chemistry2018，27，2： | 3 |

| 12 | Oxidized galectin-1 in SLE fails to bind the inhibitory receptor VSTM1 and increases reactive oxygen species levels in neutrophils显示文摘Inhibitory immune receptors set thresholds for immune cell activation,and their deficiency predisposes a person to autoimmune responses.However,the agonists of inhibitory immune receptors remain largely unknown,representing untapped sources of treatments for autoimmune diseases.Here,we show that V-set and transmembrane domain-containing 1(VSTM1)is an inhibitory receptor and that its binding by the competent ligand soluble galectin-1(Gal1)is essential for maintaining neutrophil viability mediated by downregulated reactive oxygen species production.However,in patients with systemic lupus erythematosus(SLE),circulating Gal1 is oxidized and cannot be recognized by VSTM1,leading to increased intracellular reactive oxygen species levels and reduced neutrophil viability.Dysregulated neutrophil function or death contributes significantly to the pathogenesis of SLE by providing danger molecules and autoantigens that drive the production of inflammatory cytokines and the activation of autoreactive lymphocytes.Interestingly,serum levels of glutathione,an antioxidant able to convert oxidized Gal1 to its reduced form,were negatively correlated with SLE disease activity.Taken together,our findings reveal failed inhibitory Gal1/VSTM1 pathway activation in patients with SLE and provide important insights for the development of effective targeted therapies. | Xu Jiang Xinyue Xiao Hao Li Yiyi Gong Min Wang Huaxia Yang Lidan Zhao Ying Jiang Yanping Wei Chongchong Zhao Jin Li Yuling Chen Shan Feng Haiteng Deng Shiliang Ma Yue Xu Yudong Liu George C.Tsokos Minghong Jiang Xuan Zhan | 2023 | Cellular & Molecular Immunology2023，20，11： | 1 |

| 20 | Size-fractionated uranium isotopes in surface waters in the Jiulong Estuary in China显示文摘Surface water was collected from the Jiulong Estuary for determination of activity concentrations of uranium isotopes in different size fractions,namely,greater than 53,10~53,2~10,0.4~2 μm,10 000 u^0.4 μm and less than 10 000 u fractions by microfiltration and cross-flow ultrafiltration technologies. Results indicated that most of the dissolved uranium (<0.4 μm) existed in the low molecular mass fraction (<10 000 u),and the colloidal uranium-238 (10 000 u^0.4 μm) only contributed less than 1% of the dissolved uranium-238. The fractions of colloidal uranium in the dissolved phases decreased with the increasing salinity. A positive linear relationship between uranium-238 activities and salinities was observed for the dissolved,colloidal and low molecular mass fractions,indicating a conservative behavior of uranium in the Jiulong Estuary. In the particulate phases (>0.4 μm),the partitioning of uranium isotopes among different size fractions was controlled by the partitioning of particle concentrations. In the regions with salinities below 20,the partitioning of uranium-238 among different size fractions was as follows: 10~53 μm>2~10 μm>0.4~2 μm greater than above 53 μm. However,the order at the offshore station with salinities above 30 changed as follows: 0.4~2 μm>10~53 μm>2~10 μm greater than above 53 μm. The fraction of the 0.4~2 μm particles increased at the offshore station,suggesting the increased contribution of the authigenic uranium. The activity ratio of uranium-234 to uranium-238 in the dissolved phases,including the low molecular mass fraction and the colloidal fraction,was larger than unity,showing the occurrence of excess uranium-234. In contrast,the activity ratio of uranium-234 to uranium-238 in all size fractions of the particulate phase was close to the equilibrium value (1.0). The observed different values of the activity ratio of uranium-234 to uranium-238 in the dissolved phase and the particulate phase were ascribed to the preferential leaching of uranium-234 and the small amount of the leaching particulate uranium. The mass ratio of thorium-232 to uranium-238 also showed different values between the dissolved phase and the particulate phase. Mass ratio of thorium-232 to uranium-238 in the dissolved,colloidal and low molecular mass fractions was less than unity,while those in the different size fractions of particulate phases were larger than unity,reflecting a different behavior between uranium and thorium during their transport into the ocean. | LU E ZHANG Lei CHEN Min QIU Yusheng XING Na YANG Weifeng LI Yanping HUANG Yipu | 2008 | Acta Oceanologica Sinica2008，27，1： | 1 |
