2Variations of pore water sulfate gradients in sediments as indicator for underlying gas hydrate in Shenhu Area, the South China Sea显示文摘Shenhu Area is one of the most promising areas for gas hydrate exploration in the northern South China Sea (SCS). Pore water sulfate gradient, sulfate-methane interface (SMI) depth, and sulfate flux were analyzed at 53 sites in this area. SO42 gradient ranges between 0.33 and 4.43 mmol L-1 m-1 . SMI depths are from 7.7 to 87.9mbsf. Sulfate flux varies between 2.0 and 26.9 mmol m-2 yr-1 , with a mean of 11.7 mmol m-2 yr-1 . Correlation coefficient between SMI depth and methane flux for the 53 sites is 0.80, implying that methane flux regulates the rate of anaerobic methane oxidation (AMO), SMI depth, and sulfate flux. Twelve anomalous fields with high methane flux and steep sulfate gradients were recognized. Bottom simulating reflector (BSR) is distributed mainly in areas where SMI depth is less than 50 mbsf or places with sulfate flux larger than 3.5 mmol m-2 yr-1 . It is suggested that the Baiyun Sag and the Southern Uplift are potential areas for gas hydrate exploration.WU LuShan YANG ShengXiong LIANG JinQiang SU Xin FU ShaoYing SHA ZhiBin YANG Tao 2013Science China Earth Sciences2013,56,4:24
3Clinical observation on effect of scalp electroacupuncture for mild cognitive impairment显示文摘OBJECTIVE: To evaluate the therapeutic effect of scalp electroacupuncture for mild cognitive impairment (MCI) in the early stage. METHODS: Two hundred and thirty three MCI patients were randomly divided into three groups: the drug group, the scalp electroacupuncture group, and the syndrome differentiation group. For the scalp electroacupuncture group, the points of Baihui (DU 20), Sishecong (EX-HN1), Fengchi (GB 20), and Shenting (DU 24) were selected. For the syndrome differentiation group, specific acupoints were added on the basis of syndrome differentiation and according to the scale for the differentiation of syndromes in vascular dementia (SDSVD) beside the acupoints used in the scalp electroacupuncture group. For the drug group, nimodipine was orally administered. Each patient was treated for two courses, eight weeks. The score differences in minimental state examination (MMSE), picture recognition, and clock drawing test were observed before and after the treatment. RESULTS: After treatment, the score differences in MMSE and clock drawing test were of obvious statistical significance among three groups (P<0.01, P<0.05). The score differences in picture recognition were of extremely statistical significance between the scalp electroacupuncture group and the syndrome differentiation group (P<0.01), while the difference was not found in the drug group (P>0.05). There were statistical significant differences in therapeutic effects between the scalp electroacupuncture group and the drug group, and between the syndrome differentiation group and the drug group (P<0.05), while no statistical difference was found between scalp electroacupuncture group and the syndrome differentiation group (P>0.05). CONCLUSION: All the three therapies may improve the cognitive function of MCI patients. The therapeutic effects in the scalp electroacupuncture and syndrome differentiation groups were basically the same, but superior to nimodipine.Hong Zhang Ling Zhao Sha Yang Zhigang Chen Yingkun Li Xiaohong Peng Yulong Yang Manjia Zhu 2013Journal of Traditional Chinese Medicine2013,33,1:23
4Pathways of China's PM;air quality 2015–2060 in the context of carbon neutrality显示文摘Clean air policies in China have substantially reduced particulate matter(PM;) air pollution in recent years,primarily by curbing end-of-pipe emissions.However,reaching the level of the World Health Organization(WHO) guidelines may instead depend upon the air quality co-benefits of ambitious climate action.Here,we assess pathways of Chinese PM;air quality from 2015 to 2060 under a combination of scenarios that link global and Chinese climate mitigation pathways(i.e.global 2℃-and 1.5℃-pathways,National Determined Contributions(NDC) pledges and carbon neutrality goals) to local clean air policies.We find that China can achieve both its near-term climate goals(peak emissions) and PM;air quality annual standard(35 μg/m;) by 2030 by fulfilling its NDC pledges and continuing air pollution control policies.However,the benefits of end-of-pipe control reductions are mostly exhausted by 2030,and reducing PM;exposure of the majority of the Chinese population to below 10 μg/m;by 2060 will likely require more ambitious climate mitigation efforts such as China’ s carbon neutrality goals and global1.5℃-pathways.Our results thus highlight that China’s carbon neutrality goals will play a critical role in reducing air pollution exposure to the level of the WHO guidelines and protecting public health.Jing Cheng Dan Tong Qiang Zhang Yang Liu Yu Lei Gang Yan Liu Yan Sha Yu Ryna Yiyun Cui Leon Clarke Guannan Geng Bo Zheng Xiaoye Zhang Steven JDavis Kebin He 2021National Science Review2021,8,12:23

8Types,Characteristics and Significances of Migrating Pathways of Gas-bearing Fluids in the Shenhu Area,Northern Continental Slope of the South China Sea显示文摘The first marine gas hydrate expedition in China has been conducted by Guangzhou Marine Geological Survey in the Shenhu Area, northern continental slope of the South China Sea. Previous study has analyzed the P-T conditions, geophysical anomalies and saturation calculations of these gas hydrates, but has not documented in detail the migration of gas-bearing fluids in the study area. Based on the interpretations of 2D/3D seismic data, this work identified two types of migration pathways for gas-bearing fluids in the Shenhu area, i.e., vertical and lateral pathways. The vertical pathways(largescale faults, gas chimneys and mud diapirs) presented as steep seismic reflection anomalies, which could be traced downward to the Eocene source rocks and may penetrate into the Late Miocene strata. The deeper gases/fluids might be allowed migrating into the shallower strata through these vertical conduits. However, the distributions showed distinct differences between these pathways. Large-scale faults developed only in the north and northeast of the Shenhu area, while in the drilling area gas chimneys were the sole vertical migration pathways. Since the Pliocene, normal faults, detachment faults and favorable sediments have constituted the lateral pathways in the Shenhu gas hydrate drilling area. Although these lateral pathways were connected with gas chimneys, they exerted different effects on hydrate formation and accumulation. Gas-bearing fluids migrated upward along gas chimneys might further migrate laterally because of the normal faults, thereby enlarging the range of the chimneys. Linking gas chimneys with the seafloor, the detachment faults might act as conduits for escaping gases/fluids. Re-deposited sediments developed at the early stage of the Quaternary were located within the gas hydrate stability zone, so hydrates would be enriched in these favorable sediments. Compared with the migration pathways(large-scale faults and mud diapirs) in the LW3-1 deep-sea oil/gas field, the migration efficiency of the vertical pathways(composed of gas chimneys) in the gas hydrate drilling area might be relatively low. Description and qualitative discrimination of migration pathways in the Shenhu gas hydrate drilling area are helpful to further understand the relationship between good-quality deep source rocks and shallow, mainly biogenicallyproduced, hydrates. As the main source rocks of the Baiyun sag, lacustrine mudstones in the Wenchang and Enping Formations may provide thermogenic methane. Gas chimneys with relatively low migration efficiency created the vertical pathways. Caused by the Dongsha tectonic movement, the release of overpressured fluids might reduce the vertical migration rates of the thermogenic methane. The thick bathyal/abyssal fine-grained sediments since the Late Miocene provided migration media with low permeability. These preconditions may cause carbon isotopic fractionation ofthermogenic methane during long-distance vertical migrations. Therefore, although geochemical analyses indicate that the methane forming gas hydrate in the Shenhu area was mainly produced biogenically, or was mixed methane primarily of microbial origin, thermogenic methane still contribute significantly.SU Ming SHA Zhibin ZHANG Cuimei WANG Hongbin WU Nengyou YANG Rui LIANG Jinqiang QIAO Shaohua CONG Xiaorong LIU Jie 2017Acta Geologica Sinica(English Edition)2017,91,1:16

10Sinomenine ester derivative inhibits glioblastoma by inducing mitochondria-dependent apoptosis and autophagy by PI3K/AKT/mTOR and AMPK/mTOR pathway显示文摘Glioblastoma multiforme(GBM)in the central nervous system is the most lethal advanced glioma and currently there is no effective treatment for it.Studies of sinomenine,an alkaloid from the Chinese medicinal plant,Sinomenium acutum,showed that it had inhibitory effects on several kinds of cancer.Here,we synthesized a sinomenine derivative,sino-wcj-33(SW33),tested it for antitumor activity on GBM and explored the underlying mechanism.SW33 significantly inhibited proliferation and colony formation of GBM and reduced migration and invasion of U87 and U251 cells.It also arrested the cell cycle at G2/M phase and induced mitochondria-dependent apoptosis.Differential gene enrichment analysis and pathway validation showed that SW33 exerted anti-GBM effects by regulating PI3 K/AKT and AMPK signaling pathways and significantly suppressed tumorigenicity with no obvious adverse effects on the body.SW33 also induced autophagy through the PI3 K/AKT/mTOR and AMPK/mTOR pathways.Thus,SW33 appears to be a promising drug for treating GBM effectively and safely.Xiangjin Zheng Wan Li Huanli Xu Jinyi Liu Liwen Ren Yihui Yang Sha Li Jinhua Wang Tengfei Ji Guanhua Du 2021Acta Pharmaceutica Sinica B2021,11,11:15
11The Influence of Phacoemulsification on Corneal Endothelia Cells at Varying Blood Glucose Levels显示文摘Purpose:To investigate the influence of phacoemulsification on corneal endothelial cells in diabetes patients and normal controls. Methods:Phacoemulsification and intraocular lens implantation were performed on 75 patients with diabetic cataract (126 eyes) who were divided into two groups: Trial group 1 (Glu≤6 mmol/L); Trial group 2 (Glu 6-10 mmol/L) and 65 nondiabetic controls (112 eyes).The density and percentage of hexagonal cells and coefficient of variation of the corneal endothelia were measured before surgery and 1 day,1 month and 3 months postoperatively. Results: There was no statistical difference in the density and percentage of hexagonal cells and coefficient of variation of the corneal endothelia prior to phacoemulsification.(P>0.05) between the three groups.The density and percentage of hexagonal cells of the corneal endothelia decreased significantly after surgery in all three groups(P<0.05),while the Coefficient of variation increased in all groups(P<0.05). The rate of loss of corneal endothelial cells in the diabetic groups was significantly higher than for the control group (P<0.05), the percentage of hexagonal cells in the diabetic groups was significantly lower than for the control group (P<0.05), and the coefficient of variation in the diabetic groups was significantly higher than for the control group (P<0.05) at 1 day, 1 month and 3 months post-operatively. There was no statistical difference between the two diabetic groups in terms of these post-operative measurements. Conclusion:The corneal endothelium of diabetic patients is more prone to damage from phacoemulsification. It is advisable to evaluate the corneal endothelium routinely prior to phacoemulsification, particularly in diabetic persons.RuiMing Yang Xiangyin Sha Mingbing Zeng Yingqian Tan Yu Zheng Feihong Fan 2011Eye Science2011,26,2:14

13Soil respiration in tropical seasonal rain forest in Xishuangbanna, SW China显示文摘With the static opaque chamber and gas chromatography technique, from January 2003 to January 2004 soil respiration was investigated in a tropical seasonal rain forest in Xishuangbanna, SW China. In this study three treatments were applied, each with three replicates: A (bare soil), B (soil+litter), and C (soil+litter+seedling). The results showed that soil respiration varied seasonally, low from December 2003 to February 2004, and high from June to July 2004. The annual average values of CO2 efflux from soil respiration differed among the treatments at 1% level, with the rank of C (14642 mgCO2· m-2. h-1)>B (12807 mgCO2· m-2. h-1)>A (9532 mgCO2· m-2. h-1). Diurnal variation in soil respiration was not apparent due to little diurnal temperate change in Xishuangbanna. There was a parabola relationship between soil respiration and soil moisture at 1% level. Soil respiration rates were higher when soil moisture ranged from 35% to 45%. There was an exponential relationship between soil respiration and soil temperature (at a depth of 5cm in mineral soil) at 1% level. The calculated Q1o values in this study,ranging from 2.03 to 2.36, were very near to those of tropical soil reported. The CO2 efflux in 2003was 5.34 kgCO2· m-2. a-1 from soil plus litter plus seedling, of them 3.48 kgCO2· m-2. a-1 from soil (accounting for 62.5%), 1.19 kgCO2· m-2. a-1 from litter (22.3%) and 0.67 kgCO2·m-2. a-1 from seedling (12.5%).SHA Liqing, ZHENG Zheng, TANG Jianwei, WANG Yinghong, ZHANG Yiping, CAO Min, WANG Rui, LIU Guangren, WANG Yuesi & SUN Yang Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences, Kunming 650223, China Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing 100029, China Graduate School of Chinese Academy of Sciences, Beijing 100039, China 2005Science China Earth Sciences2005,48,z1:12
14A commentary review on the use of normalized diff erence vegetation index(NDVI)in the era of popular remote sensing显示文摘The Normalized Diff erence Vegetation Index(NDVI),one of the earliest remote sensing analytical products used to simplify the complexities of multi-spectral imagery,is now the most popular index used for vegetation assessment.This popularity and widespread use relate to how an NDVI can be calculated with any multispectral sensor with a visible and a near-IR band.Increasingly low costs and weights of multispectral sensors mean they can be mounted on satellite,aerial,and increasingly—Unmanned Aerial Systems(UAS).While studies have found that the NDVI is effective for expressing vegetation status andquantified vegetation attributes,its widespread use and popularity,especially in UAS applications,carry inherent risks of misuse with end users who received little to no remote sensing education.This article summarizes the progress of NDVI acquisition,highlights the areas of NDVI application,and addresses the critical problems and considerations in using NDVI.Detailed discussion mainly covers three aspects:atmospheric eff ect,saturation phenomenon,and sensor factors.The use of NDVI can be highly eff ective as long as its limitations and capabilities are understood.This consideration is particularly important to the UAS user community.Sha Huang Lina Tang Joseph P.Hupy Yang Wang Guofan Shao 2021Journal of Forestry Research2021,32,1:12

16Experimental study of rotor blades vibration and noise in multistage high pressure compressor and their relevance显示文摘Rotor blades fault of aeroengine compressor is mostly caused by mechanical and aerodynamic excitation.And the excitation factor of high intensity sound wave to rotor blades should not be ignored.Experimental researches are conducted on a multistage high pressure compressor.When high level vibration occurs on the first stage of rotor blades, the noise spectrum presents typical characteristic for discrete multi-tone in the compressor.The amplitude of blade vibration displacement and the sound pressure level of characteristic frequency noise increases and decreases simultaneously and reaches the maximum value at the same time.This frequency merely occur on a certain speed range and is locked in a specific range which presents no variation with the rotating speed.When high level vibration occurs on the first stage of rotor blades, the noise spectrum presents a sharp peak and the propagation state of the characteristic frequency is a helix structure in the compressor.It can be confirmed that acoustic resonance occurs in the multistage compressor.The acoustic resonance frequency and its side band frequencies are generated by modulation of a rotating noise source at the rotor speed which is the excitation source of the rotor blades vibration.Fengtong ZHAO Xiaodong JING Mingsui YANG Deyou WANG Yundong SHA Xiaochi LUAN 2020Chinese Journal of Aeronautics2020,33,3:11
17A systematic review of metabolomic profiling of gastric cancer and esophageal cancer显示文摘Objective:Upper gastrointestinal(UGI)cancers,predominantly gastric cancer(GC)and esophageal cancer(EC),are malignant tumor types with high morbidity and mortality rates.Accumulating studies have focused on metabolomic profiling of UGI cancers in recent years.In this systematic review,we have provided a collective summary of previous findings on metabolites and metabolomic profiling associated with GC and EC.Methods:A systematic search of three databases(Embase,PubMed,and Web of Science)for molecular epidemiologic studies on the metabolomic profiles of GC and EC was conducted.The Newcastle–Ottawa Scale(NOS)was used to assess the quality of the included articles.Results:A total of 52 original studies were included for review.A number of metabolites were differentially distributed between GC and EC cases and non-cases,including those involved in glycolysis,anaerobic respiration,tricarboxylic acid cycle,and protein and lipid metabolism.Lactic acid,glucose,citrate,and fumaric acid were among the most frequently reported metabolites of cellular respiration while glutamine,glutamate,and valine were among the most commonly reported amino acids.The lipid metabolites identified previously included saturated and unsaturated free fatty acids,aldehydes,and ketones.However,the key findings across studies to date have been inconsistent,potentially due to limited sample sizes and the majority being hospital-based case-control analyses lacking an independent replication group.Conclusions:Studies on metabolomics have thus far provided insights into etiological factors and biomarkers for UGI cancers,supporting the potential of applying metabolomic profiling in cancer prevention and management efforts.Sha Huang Yang Guo Zhexuan Li Yang Zhang Tong Zhou Weicheng You Kaifeng Pan Wenqing Li 2020Cancer Biology & Medicine2020,17,1:11
18A multiplex PCR for differential detection of Echinococcus granulosus sensu stricto,Echinococcus multilocularis and Echinococcus canadensis in China显示文摘Background:Echinococcosis caused byEchinococcus is one of the most major infectious diseases in north-west highland of China.E.granulosus sensu strict,E.multilocularis,andE.canadensis are known to be the only three species related to human health transmitting in the areas.To achieve targeted treatment and control of echinococcosis,the accurate identification and discrimination of the species are important.However,currently the available diagnostic approaches do not present ideal results either in accuracy or efficiency.Methods:In the study,a set of primers were designed to aim at the three human-pathogenicEchinococcus species in China.The one-step multiplex PCR assay was developed and evaluated for the specificity and sensitivity.A total of 73parasitic lesions and 41 fecal materials obtained from human and various animals collected in the clinic and the field were tested to assess the applicability of this method.Results:The multiplex PCR effectively detected the individual DNA from the targeted species and their random mixtures generating with distinguishable expected size of products.The detection limit of the assay for each of the three species was 5 pg/μl when they were tested separately.When DNA mixtures of the targeted species containing the same concentration were used as templates,the lowest amount of DNA which can be detected was 50 pg/μl,10 pg/μl and 5 pg/μl forE.granulosus s.s.,E.multilocularis,andE.canadensis respectively.No cross-reactivity was observed when DNA from eight genetically close species was used as control templates.The multiplex PCR identifications of all samples were in line with the original sequencing results except for those infected withE.shiquicus,which showed negative signals in the developed assay.Of all the tested stool materials,16 were previously found positive forEchinococcus by visual and microscopic examination.Among these 16 samples,13 were confirmed by the multiplex PCR,and the other three tested negative.Additionally,the multiplex PCR identified another 14 positive feces from the remained 25 stool samples which absence of worms.Conclusions:The developed multiplex PCR shows advantages in fast diagnosis and large-scale epidemiological investigation,which proven to be a promising tool utilized in clinic and surveillance system.Jing-Ye Shang Guang-Jia Zhang Sha Liao Yan Huang Wen-Jie Yu Wei He Guang-You Yang Tiao-Ying Li Xing-Wang Chen Bo Zhong Qian Wang Qi Wang Rui-Rui Li Hao Wang 2019Infectious Diseases of Poverty2019,8,4:11
