1Antidiabetic Effects of Gegen Qinlian Decoction via the Gut Microbiota Are Attributable to Its Key Ingredient Berberine显示文摘Gegen Qinlian Decoction(GQD),a traditional Chinese medicine(TCM)formula,has long been used for the treatment of common metabolic diseases,including type 2 diabetes mellitus.However,the main limitation of its wider application is ingredient complexity of this formula.Thus,it is critically important to identify the major active ingredients of GQD and to illustrate mechanisms underlying its action.Here,we compared the effects of GQD and berberine,a hypothetical key active pharmaceutical ingredient of GQD,on a diabetic rat model by comprehensive analyses of gut microbiota,short-chain fatty acids,proinflammatory cytokines,and ileum transcriptomics.Our results show that berberine and GQD had similar effects on lowering blood glucose levels,modulating gut microbiota,inducing ileal gene expression,as well as relieving systemic and local inflammation.As expected,both berberine and GQD treatment significantly altered the overall gut microbiota structure and enriched many butyrate-producing bacteria,including Faecalibacterium and Roseburia,thereby attenuating intestinal inflammation and lowering glucose.Levels of short-chain fatty acids in rat feces were also significantly elevated after treatment with berberine or GQD.Moreover,concentration of serum proinflammatory cytokines and expression of immune-related genes,including Nfkb1,Stat1,and Ifnrg1,in pancreatic islets were significantly reduced after treatment.Our study demonstrates that the main effects of GQD can be attributed to berberine via modulating gut microbiota.The strategy employed would facilitate further standardization and widespread application of TCM in many diseases.Xizhan Xu Zezheng Gao Fuquan Yang Yingying Yang Liang Chen Lin Han Na Zhao Jiayue Xu Xinmiao Wang Yue Ma Lian Shu Xiaoxi Hu Na Lyu Yuanlong Pan Baoli Zhu Linhua Zhao Xiaolin Tong Jun Wang 2020Genomics, Proteomics & Bioinformatics2020,18,6:29
2Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12
3Chinese herbal medicine reduces mortality in patients with severe and critical coronavirus disease 2019: a retrospective cohort study显示文摘This study aimed to evaluate the efficacy of Chinese herbal medicine(CHM)in patients with severe/critical coronavirus disease 2019(COVID-19).In this retrospective study,data were collected from 662 patients with severe/critical COVID-19 who were admitted to a designated hospital to treat patients with severe COVID-19 in Wuhan before March 20,2020.All patients were divided into an exposed group(CHM users)and a control group(non-users).After propensity score matching in a 1:1 ratio,156 CHM users were matched by propensity score to 156 non-users.No significant differences in seven baseline clinical variables were found between the two groups of patients.All-cause mortality was reported in 13 CHM users who died and 36 non-users who died.After multivariate adjustment,the mortality risk of CHM users was reduced by 82.2%(odds ratio 0.178,95%CI 0.076–0.418;P<0.001)compared with the non-users.Secondly,age(odds ratio 1.053,95%CI 1.023–1.084;P<0.001)and the proportion of severe/critical patients(odds ratio 0.063,95%CI 0.028–0.143;P<0.001)were the risk factors of mortality.These results show that the use of CHM may reduce the mortality of patients with severe/critical COVID-19.Guohua Chen Wen Su Jiayao Yang Dan Luo Ping Xia Wen Jia Xiuyang Li Chuan Wang Suping Lang Qingbin Meng Ying Zhang Yuhe Ke An Fan Shuo Yang Yujiao Zheng Xuepeng Fan Jie Qiao Fengmei Lian Li Wei Xiaolin Tong 2020Frontiers of Medicine2020,14,6:10

5Surface pollen distribution patterns in Beibu Gulf and corresponding sediment dynamics environment显示文摘The Beibu Gulf is a semi-enclosed gulf in the northwest of the South China Sea.We palynologically analyzed 306 surface sediment samples from the eastern Beibu Gulf to improve bioclimatic interpretation of fossil pollen records there.Surface pollen assemblages could be classified into five pollen regions based on the distributions of total,arboreal,herbaceous and fern pollen concentrations.Four high-concentration and three low-concentration subregions could be distinguished within these regions.The distribution patterns of surface pollen assemblages were consistent with those of grain sizes of surface sediments.Sediments from regions with high pollen concentrations were very fine and fine silts (>7.0,<0.008 mm),whereas those with low pollen concentrations were fine sand (<3.5,>0.088 mm).Sedimentary heterogeneity of surface pollen assemblages was closely related to pollen source,transportation and sedimentation controlled by ocean currents,tides and waves,and oceanic bottom topography.Fern spores exhibited higher percentages along the east margins of the region,while arboreal types like Pinus increased in concentration towards the center.Herbaceous pollen appeared in high percentages around seacoasts near their source areas.Dacrydium and mangrove pollen were distributed near their source regions at low percentages.We discuss the sediment dynamic environments in the eastern Beibu Gulf based on surface pollen distributions.The estuary region is an important access to the sea basin and a depositional site for terrestrial pollen grains.Coastal regions can accumulate pollen due to the back-and-forth movements of tides there.Although ocean currents on a gulf scale tend to spread pollen grains,the interaction of multiple currents could lead to pollen accumulation and deposition.Low surface pollen concentrations in the northeast shallow-water regions of the eastern Beibu Gulf could be attributed to repeated washing and sediment floatation caused by severe wave activities during the summer.Strong tides in Qiongzhou Strait frequently wash the seabed and disadvantage pollen deposition,leading to low surface pollen concentrations there.TONG GuoBan CHEN Lian LONG JiangPing LI TuanJie XIAO XiaYun TONG SongMei 2012Chinese Science Bulletin2012,57,8:8
6Efficacy of Shenzhuo formula on diabetic kidney disease:a retrospective study显示文摘OBJECTIVE:To observe the efficacy of a traditional Chinese medicine,Shenzhuo formula,on patients with diabetic kidney disease(DKD).METHODS:Eighty-eight outpatients with DKD were enrolled.Changes in estimated glomerular filtration rate(eGFR),creatinine clearance,serum creatinine,blood-urea-nitrogen,albuminuria,glycosylated hemoglobin(Hb_(A1C)),blood pressure,and lipid profile were measured and analyzed before and after intervention with Shenzhuo formula for 1,3,6,9,12,and 18 months.RESULTS:Compared with the baseline amounts,serum creatinine decreased,and eGFR and creatinine clearance increased,significantly after intervention for 1,3,6,9,12,and 18 months(all P < 0.05).Mean eGFR increased by 2.11 mL/min per 1.73 m7 y after18-month treatment.Urinary protein at 24 h decreased significantly after 1,3,9,and 12 months(P < 0.05).Hb_(A1C) decreased significantly(P < 0.05) after 3,6,9,12,and 18 months,and systolic blood pressure decreased significantly(P < 0.05) after 1,3,and 6 months.Total cholesterol decreased significantly(P < 0.05) after 1,3,6,and 18 months.Triglyceride and low-density lipoprotein-cholesterol decreased significantly(P < 0.05) after 1 and 3 months.CONCLUSION:Shenzhuo formula can improve eGFR and possibly slow DKD progression.Shenzhuo formula can also lower Hb_(A1C),lipid levels and blood pressure.Tian Jiaxing Zhao Linhua Zhou Qiang Liu Wenke Chen Xinyan Lian Fengmei Tong Xiaolin 2015Journal of Traditional Chinese Medicine2015,35,5:8

9Ectomycorrhizal Fungi in Jiangsu Province,China显示文摘A survey was conducted for about 3 years to study the abundance and diversity of ectomycorrhizal fungi (EMF) in Jiangsu Province, China. The identification of the fungal species was based on the microscopic and macroscopic characteristics of their fruiting bodies. About 126 species of EMF were found in Jiangsu Province. These fungi were largely categorized into three orders (of 121 species), four families (of 96 species), and six genera (of about 86 species).LIAN Bin DONG Yuan-Rong HOU Wei-Guo TONG Li-Hua YUAN Sheng 2007Pedosphere2007,17,1:7
10Light absorption properties and potential sources of brown carbon in Fenwei Plain during winter 2018–2019显示文摘A distinctive kind of organic carbon aerosol that could absorb ultraviolet-visible radiation is called brown carbon(Br C),which has an important positive influence on radiative budget and climate change.In this work,we reported the absorption properties and potential source of Br C based on a seven-wavelength aethalometer in the winter of 2018–2019 at an urban site of Sanmenxia in Fenwei Plain in central China.Specifically,the mean value of Br C absorption coefficient was 59.6±36.0 Mm^(-1) at 370 nm and contributed 37.7%to total absorption,which made a significant impact on visibility and regional environment.Absorption coefficients of Br C showed double-peak pattern,and Br C had shown small fluctuations under haze days compared with clean days.As for the sources of Br C,Br C absorption coefficients expressed strong correlations with element carbon aerosols and primary organic carbon aerosols,indicating that most of Br C originated from primary emissions.The linear correlations between trace metal elements(K,As,Fe,Mn,Zn,and Pb)and Br C absorption coefficients further referred that the major sources of Br C were primary emissions,like coal burning,biomass burning,and vehicle emissions.The moderate relationship between Br C absorption coefficients and secondary organic aerosols suggested that secondary production of Br C also played an important role.The 120 hr backward air mass trajectories analysis and concentration-weighted trajectories analysis were also used to investigate potential sources of Br C in and around this area,which inferred most parts of Br C were derived from local emissions.Wenyu Zhang Weigang Wang Jie Li Shuangliang Ma Chaofan Lian Kun Li Bo Shi Mingyuan Liu Yanyu Li QingQing Wang Yele Sun Shengrui Tong Maofa Ge 2021Journal of Environmental Sciences2021,33,4:6
11Characteristics of deep drainage and soil water in the mobile sandy lands of Inner Mongolia, northern China显示文摘Quantification of deep drainage and the response of soil water content to rainfall patterns are critical for an effective management strategy of soil water conservation and groundwater utilization. However, there has been little information on how rainfall characteristics influence soil water dynamics and deep drainage in mobile sandy lands. We used an underground chamber to examine the responses of deep drainage and soil water content in mobile sandy lands to rainfall characteristics in Inner Mongolia during the growing seasons of 2010, 2011 and 2012. Results showed that rainfall in this area was dominated by small events(≤5 mm), which increased soil water content in the surface soil layers(0–40 cm), but did not increase soil water content in the deeper soil layers(greater than 40 cm). Soil water content at the 0–100 cm depth increased significantly when the total amount of rain was >20 mm. Rainfall amount, intensity and the duration of dry intervals were significantly related to the soil water content in different soil layers. Deep drainage was significantly correlated with rainfall amount and intensity, but not with the duration of dry intervals. The coefficients of deep drainage in the mobile sandy lands ranged from 61.30% to 67.94% during the growing seasons. Our results suggested that rainfall infiltration in the mobile sandy lands had considerable potential to increase soil water storage while recharging the groundwater in this region.Xin Ping LIU Yu Hui HE Xue Yong ZHAO Tong Hui ZHANG La Mei ZHANG Yun Hua MA Shu Xia YAO Shao Kun WANG Shui Lian WEI 2015Journal of Arid Land2015,7,2:4
12Resveratrol elongates the lifespan and improves antioxidant activity in the silkworm Bombyx mori显示文摘A number of research has shown that the plant polyphenol resveratrol,one of the most prominent small molecules,has beneficial protective effects in multiple organisms,including worms,flies,and killifish.To understand the effects of resveratrol on lifespan,we evaluated its effects in the silkworm Bombyx mori.In this study,we found that lifespan was significantly prolonged in both female and male silkworms treated with resveratrol.Silkworm larval weight was significantly increased from day 3 of the 5th larval instar(L5D3)to day 7 of the 5th larval instar(L5D7).However,the weight of the pupa,cocoon,and total cocoon was not significantly different in female silkworms with resveratrol treatment than that in controls.Meanwhile,resveratrol significantly improved the thermotolerance of the silkworms,which enhanced their survival rate.Moreover,antioxidant activity was increased by resveratrol in both female and male silkworms.Furthermore,an antioxidant-related signalling pathway,SIRT7-FoxO-GST,was activated in silkworms with resveratrol treatment.Collectively,these results help us to understand the molecular pathways underlying resveratrol induced pro-longevity effects and indicate that silkworm is a promising animal model for evaluating the effects of lifespan-extending drugs.Jiangbo Song Lian Liu Kaige Hao Shuang Mao Yongxi Tang Xiaoling Tong Fangyin Dai 2021Journal of Pharmaceutical Analysis2021,11,3:4
13Dose-effect analysis of treatment by modified Zhibaidihuang decoction on polycystic ovary syndrome hyperandrogenism显示文摘OBJECTIVE: To observe the efficacy and safety of different dosages of modified Zhibaidihuang decoction(MZBDD) on polycystic ovary syndrome(PCOS) hyperandrogenism(HA) patients.METHODS: Ninety PCOS HA patients and 30 infertile patients due to tubal factor were selected. Ninety PCOS HA patients were randomly divided into three groups: low dosage group(LDG), medium dosage group(MDG) and high dosage group(HDG) and infertile patients were selected as normal control group(NCG). PCOS HA patients were treated with different dosage of MZBDD for 4 weeks. For HA patients, serum total testosterone(T), estrodial(E2), follicle stimulating hormone(FSH), luteinizing hormone(LH), prolatin(PRL), alanine aminotransferase(AST), aspartate amino transferase(AST) were determined before and after treatment, while acne scores(Rosenfield) were signed. Basal body temperatures(BBT) were asked to be measured every day. And for the else, T, E2,FSH, LH, PRL, AST, and AST were determined before treatment.RESULTS: Totally 111 patients completed the clinical research. There were no differences among the four groups on serum T before treatment(P =0.221). Serum T concentration of both MDG and HDG after treatment significantly were lower than that of before treatment(P = 0.039, P = 0.000),while there was no obvious difference in LDG(P =0.829). Serum T concentration of both MDG and HDG were significantly lower than that of LDG after treatment(P = 0.048, P = 0.006). To compared with before treatment, there were no differences in Serum FSH, LH, E2, P and PRL among the three groups(LDG, MDG, HDG)(as for FSH, P = 0.136, P = 0.503,P = 0.062; as for LH, P = 0.473, P = 0.513, P = 0.096;as for E2, P = 0.206, P = 0.927, P = 0.076; as for PRL,P = 0.120, P = 0.903, P = 0.407, as for P, P = 0.308, P =0.866, P = 0480). Acne scores of all the three groups were obviously lower than that of before treatment(P = 0.031; P = 0.033; P = 0.002). 39.5% of the patients had biphasic BBT, but there were no differences among the three groups(P = 0.510). There were no differences with ALT and AST between after and before treatment among the three groups(LDG, MDG, HDG)(as for ALT, P = 0.742, P = 0.383,P = 0.053; as for AST, P = 0.732, P = 0.519, P = 0.120).CONCLUSION: Different dosage of MZBDD has dose-effect relationship in treating PCOS HA.Zhao Yiming Zheng Dongxue Cheng Ran Xu Xin Lian Fengmei Tong Xiaolin Liu Xinmin 2018Journal of Traditional Chinese Medicine2018,38,2:4
14A comparison between acute large vessel occlusion in the posterior circulation and anterior circulation after endovascular treatment:the ANGEL-ACT registry experience显示文摘Background and purpose Endovascular treatment(EVT)has shown an overwhelming benefit for acute anterior circulation artery occlusion(ACO).Whether it can achieve the same outcomes in posterior circulation artery occlusion(PCO)has not been well explained.We aimed to evaluate the characteristics and prognosis of ACO and PCO after EVT in a nationwide registry.Method The present analysis was based on the prospective ANGEL-ACT Registry in China between November 2017 and March 2019.Demographic data,periprocedural times,recanalisation rate,intracranial haemorrhage(ICH)and 90-day functional outcomes were compared between the ACO and PCO groups.Results A total of 1793 patients were analysed including 397(22.1%)consecutive patients with PCO and 1396(77.9%)patients with ACO treated with EVT.A larger proportion of patients with PCO had intracranial atherosclerotic disease and received extra angioplasty during EVT.Successful recanalisation and 90-day favourable functional outcomes did not differ significantly between the two groups.Patients with PCO showed lower 24-hour ICH and symptomatic ICH rates.There was a trend towards higher mortality rate in the PCO group(22.09%vs 14.44%;adjusted OR 1.286(95%CI 0.820 to 2.017),p=0.2731),especially when the onset to puncture time was over 6 hours(30.77%vs 11.13%;adjusted OR 2.673(95%CI 1.280 to 5.583),p=0.0089,interactive p=0.0002).Conclusions In this large prospective multicentre registry,there was a significant difference in the characteristics and periprocedural features between patients with PCO and ACO.However,successful recanalisation and 90-day favourable functional outcomes in PCO were equivalent to those in ACO.Xuan Sun Jingyu Zhang Xu Tong Baixue Jia Dapeng Mo Ning Ma Feng Gao Lian Liu Xiaochuan Huo Ligang Song Yiming Deng Zhongrong Miao 2022Stroke & Vascular Neurology2022,7,4:4

16Immunological Evaluation of a Novel Mycobacterium tuberculosis Antigen Rv0674显示文摘Objective This study aimed to characterize the diagnostic and vaccine potential of a novel Mycobacterium tuberculosisantigen Rv0674. Methods To evaluate thediagnostic potential and antigenicity of Rv0674, IgG was evaluated using ELISA and interferon (IFN)-γ was done by using ELISpot assay among TB patients and healthy donors. For immunogenicity evaluation, BALB/c mice were immunized with Rv0674. Cytokine production was determined by cytokine release assay using an ELISA kit, and the antibodies were tested using ELISA. Results The results of serum Elisa tests showed that Rv0674 specific immunoglobulin G (IgG) response was higher in TB patients than negative controls. And Rv0674 had good performance in serological test with sensitivity and specificity of 77.1% and 81.1%, respectively. While it shows poor sensitivity and specificity of 26.23% and 79.69% for IFN-γ tests. In BALB/c mice, Rv0674 adjuvant by DDA/PolyI:C could also induce a high level of IFN-γ, interleukin-2 and interleukin-6 as well as a high IgG titer in both high-and low-dose groups indicating that Rv0674 is essential in humoral and cellular immunity. Moreover, the cytokine profile and IgG isotypecharacterized Rv0674 as a Th1/Th2-mixed-type protective immunity with the predominance of Th1 cytokines. Conclusion Rv0674 may be a good potential candidate for the development of TB serological diagnosis and a new TB vaccine.XIAO Tong Yang LIU Hai Can LI Xiao Qin HUANG Ming Xiang LI Gui Lian LI Na YAN Yu Han LUO Qiao WANG Xue Zhi LI Ma Chao WAN Kang Lin 2019Biomedical and Environmental Sciences2019,32,6:3
17Preliminary Study on Drug Susceptibility Profile and Resistance Mechanisms to Macrolides of Clinical Isolates of Non-tuberculous Mycobacteria from China显示文摘Objective Macrolide susceptibility and drug resistance mechanisms of clinical non-tuberculous mycobacteria(NTM) isolates were preliminarily investigated for more accurate diagnosis and treatment of the infection in China. Methods Four macrolides, including clarithromycin(CLAR), azithromycin(AZM), roxithromycin(ROX), and erythromycin(ERY), were used to test the drug susceptibility of 310 clinical NTM isolates from six provinces of China with the broth microdilution method. Two resistance mechanisms, 23 S r RNA and erm, were analyzed with nucleotide sequence analysis. Results Varied effectiveness of macrolides and species-specific resistance patterns were observed. Most Mycobacterium abscessus subsp. massiliense were susceptible and all M. fortuitum were highly resistant to macrolides. All the drugs, except for erythromycin, exhibited excellent activities against slow-growing mycobacteria, and drug resistance rates were below 22.2%. Only four highly resistant strains harbored 2,058/2,059 substitutions on rrl and none of other mutations were related to macrolide resistance. G2191 A and T2221 C on rrl were specific for the M. abscessus complex(MABC). Seven sites, G2140 A, G2210 C, C2217 G, T2238 C, T2322 C, T2404 C, and A2406 G, were specifically carried by M. avium and M. intracellulare. Three sites, A2192 G, T2358 G, and A2636 G, were observed only in M. fortuitum and one site G2152 A was specific for M. gordonae. The genes erm(39) and erm(41) were detected in M. fortuitum and M. abscessus and inducible resistance was observed in relevant sequevar. Conclusion The susceptibility profile of macrolides against NTM was demonstrated. The well-known macrolide resistance mechanisms, 23 S r RNA and erm, failed to account for all resistant NTM isolates, and further studies are warranted to investigate macrolide resistance mechanisms in various NTM species.LI Fu LI Gui Lian PANG Hui LIU Hai Can XIAO Tong Yang LI Shuang Jun LUO Qiao JIANG Yi WANG Rui Bai WAN Kang Lin 2018Biomedical and Environmental Sciences2018,31,4:3
18Helicobacter pylori antibody responses in association with eradication outcome and recurrence: a population-based intervention trial with 7.3-year follow-up in China显示文摘Objective:To identify serum biomarkers that may predict the short or long term outcomes of anti-Helicobacter pylori(H.pylori)treatment,a follow-up study was performed based on an intervention trial in Linqu County,China.Methods:A total of 529 subjects were selected randomly from 1,803 participants to evaluate total anti-H.pylori immunoglobulin G(Ig G)and 10 specific antibody levels before and after treatment at 1-,2-and 7.3-year.The outcomes of anti-H.pylori treatment were also parallelly assessed by 13C-urea breath test at 45-d after treatment and 7.3-year at the end of follow-up.Results:We found the medians of anti-H.pylori Ig G titers were consistently below cut-off value through 7.3years in eradicated group,however,the medians declined in recurrence group to 1.2 at 1-year after treatment and slightly increased to 2.0 at 7.3-year.While the medians were significantly higher(>3.0 at 2-and 7.3-year)among subjects who failed the eradication or received placebo.For specific antibody responses,baseline seropositivities of Fli D and Hpa A were reversely associated with eradication failure[for Fli D,odds ratio(OR)=0.44,95%confidence interval(95%CI):0.27–0.73;for Hpa A,OR=0.32,95%CI:0.17–0.60].The subjects with multiple positive specific antibodies at baseline were more likely to be successfully eradicated in a linear fashion(Ptrend=0.006).Conclusions:Our study suggested that total anti-H.pylori Ig G level may serve as a potential monitor of longterm impact on anti-H.pylori treatment,and priority for H.pylori treatment may be endowed to the subjects with multiple seropositive antibodies at baseline,especially for Fli D and Hap A.Tianyi Wang Yang Zhang Huijuan Su Zhexuan Li Lian Zhang Junling Ma Weidong Liu Tong Zhou Weicheng You Kaifeng Pan 2017Chinese Journal of Cancer Research2017,29,2:3
19The MING proposal at SHINE:megahertz cavity enhanced X‑ray generation显示文摘The cavity-based X-ray free-electron laser(XFEL)has promise in producing fully coherent pulses with a bandwidth of a few meV and very stable intensity,whereas the currently existing self-amplified spontaneous emission(SASE)XFEL is capable of generating ultra-short pulses with chaotic spectra.In general,a cavity-based XFEL can provide a spectral brightness three orders of magnitude higher than that of the SASE mode,thereby opening a new door for cutting-edge scientific research.With the development of superconducting MHz repetition-rate XFEL facilities such as FLASH,European-XFEL,LCLS-II,and SHINE,practical cavity-based XFEL operations are becoming increasingly achievable.In this study,megahertz cavity enhanced X-ray generation(MING)is proposed based on China’s first hard XFEL facility-SHINE,which we refer to as MING@SHINE.Nan‑Shun Huang Zi‑Peng Liu Bang‑Jie Deng Zi‑Han Zhu Shao‑Hua Li Tao Liu Zheng Qi Jia‑Wei Yan Wei Zhang Sheng‑Wang Xiang Yang‑Yang Lei Ya Zhu Yong‑Zhou He Qi‑Bing Yuan Fei Gao Rong‑Bing Deng Sen Sun Zhi‑Di Lei Zhi‑Qiang Jiang Meng‑Qi Duan Yuan Zhuan Xue‑Fang Huang Peng‑Cheng Dong Zhong‑Liang Li Shang‑Yu Si Lian Xue Si Chen Yong‑Fang Liu Ya‑Jun Tong Hai‑Xiao Deng Zhen‑Tang Zhao 2023Nuclear Science and Techniques2023,34,1:2
20Life History Recorded in the Vagino-cervical Microbiome Along with Multi-omes显示文摘The vagina contains at least a billion microbial cells,dominated by lactobacilli.Here we perform metagenomic shotgun sequencing on cervical and fecal samples from a cohort of 516 Chinese women of reproductive age,as well as cervical,fecal,and salivary samples from a second cohort of 632 women.Factors such as pregnancy history,delivery history,cesarean section,and breastfeeding were all more important than menstrual cycle in shaping the microbiome,and such information would be necessary before trying to interpret differences between vagino-cervical microbiome data.Greater proportion of Bifidobacterium breve was seen with older age at sexual debut.The relative abundance of lactobacilli especially Lactobacillus crispatus was negatively associated with pregnancy history.Potential markers for lack of menstrual regularity,heavy flow,dysmenorrhea,and contraceptives were also identified.Lactobacilli were rare during breastfeeding or post-menopause.Other features such as mood fluctuations and facial speckles could potentially be predicted from the vagino-cervical microbiome.Gut and salivary microbiomes,plasma vitamins,metals,amino acids,and hormones showed associations with the vagino-cervical microbiome.Our results offer an unprecedented glimpse into the microbiota of the female reproductive tract and call for international collaborations to better understand its long-term health impact other than in the settings of infection or pre-term birth.Zhuye Jie Chen Chen Lilan Hao Fei Li Liju Song Xiaowei Zhang Jie Zhu Liu Tian Xin Tong Kaiye Cai Zhe Zhang Yanmei Ju Xinlei Yu Ying Li Hongcheng Zhou Haorong Lu Xuemei Qiu Qiang Li Yunli Liao Dongsheng Zhou Heng Lian Yong Zuo Xiaomin Chen Weiqiao Rao Yan Ren Yuan Wang Jin Zi Rong Wang Na Liu Jinghua Wu Wei Zhang Xiao Liu Yang Zong Weibin Liu Liang Xiao Yong Hou Xun Xu Huanming Yang Jian Wang Karsten Kristiansen Huijue Jia 2022Genomics, Proteomics & Bioinformatics2022,20,2:2
