| 1 | Expert consensus on the glycemic management of critically ill patients显示文摘Introduction The incidence of hyperglycemia is 40-60%in critically ill patients and is up to 60-80%in those who have undergone car-diac surgery.[1]The results of an epidemiological study in the United States showed that 28.6%of diabetic patients and 9.3%of non-diabetic patients had elevated mean daily glucose on the day of ICU admission.[2]In critically ill patients,elevated blood glucose is primarily the result of stress,and stress-induced hy-perglycemia is an independent risk factor associated with prog-nosis,regardless of a previous diagnosis of diabetes.Nutritional therapy has become an integral treatment option for patients in the ICU,[3,4]though nearly 30%of patients with enteral nu-trition and 44-50%with parenteral nutrition(PN)experience elevated glucose.[5,6]Intensive insulin therapy(IIT)is an impor-tant treatment for controlling hyperglycemia in critically ill pa-tients,but it also carries a corresponding risk of hypoglycemia. | Zhixiong Wu Jiao Liu Dong Zhang Kai Kang Xiangrong Zuo Qianghong Xu Aijun Pan Wei Fang Fen Liu You Shang Haiyan Yin Juntao Hu Jinglun Liu Jiangquan Fu Wei Zhang Yuan Zong Min Shao Feng Zhao Mei Meng Yanfei Mao Yingchuan Li Dechang Chen | 2022 | Journal of Intensive Medicine2022，2，3： | 9 |
| 2 | Effects of Soil Texture on the Growth of Young Apple Trees and Soil Microbial Community Structure Under Replanted Conditions显示文摘A two-year field experiment was carried out in order to study the occurrence degree and mechanism of apple replant disease(ARD)in the apple orchards with different soil textures.So we can adopt appropriate controlmeasures according to the severity of ARD.Healthy two-year-old seedlings with consistent growth were selected,of which the root stock was T337 and the scion was Yanfu 3.There were significant differences in biomass between methyl bromide fumigation and replanted treatments,and the difference was the largest in clay loam,followed by sandy loam,and loam,which verified ARD in clay loam was most serious,followed by sandy loam and loam.Based on high-throughput sequencing of fungi in soil samples,fungal richness and diversity were the highest in clay loam,followed by sandy loam,and loam.The relative abundance of Fusarium in SX,SL,FX,FL,WX and WL was 7.33%,19.32%,2.70%,4.24%,10.71%and 23.87%,respectively.Based on Real-time quantitative analysis,there were significant differences in the number of Fusarium oxysporum and Fusarium solani between methyl bromide fumigation and replanted treatments,i.e.,clay loam>sandy loam>loam.Fusarium was the main pathogen causing ARD.This shows that ARD is the most serious under replanted clay loam condition.High-throughput sequencing technology was used to prove the difference in Fusarium was one of the important reasons for ARD under different soil textures.This technology provides a new idea for the prevention and control of ARD. | Yuefan Sheng Haiyan Wang MeiWang Hanhao Li Li Xiang Fengbing Pan Xuesen Chen Xiang Shen Chengmiao Yin Zhiquan Mao | 2020 | Horticultural Plant Journal2020，6，3： | 7 |
| 3 | Symptoms of long-term exposure to moxa smoke in acupuncturists: a correlation analysis显示文摘OBJECTIVE: To investigate the effects of long-term exposure to moxa smoke on acupuncturists and to consider the association between physical symptoms and gender, age, secondhand smoke(SHS) exposure, and the duration of exposure.METHODS: A self-report, web-based questionnaire was used to evaluate the effects of moxa smoke onacupuncturists. Logistic regression was used to analyze the relationship between physical symptoms and possible correlative factors.RESULTS: A total of 858 questionnaires were analyzed. The data showed that 42.42% of acupuncturists had been exposed to moxa smoke for 5-10 years. The most frequent symptom was tearing(32.98%) and the least frequent symptom was asthma(5.24%). Logistic regression analysis showed that female acupuncturists were slightly more susceptible to cough and tearing than males(cough:OR: 1.583, 95% CI: 1.079, 2.321, P = 0.019; tearing:OR: 1.519, 95% CI: 1.094, 2.108, P = 0.013). Acupuncturists aged over 25 years reported a slightly lower incidence of eye itchiness than those aged under25 years(26-40 years: OR: 0.604, 95% CI: 0.379,0.965, P = 0.035; over 40 years: OR: 0.330, 95% CI:0.114, 0.958, P = 0.042). Ophthalmodynia occurred less in acupuncturists aged 26-40 years(OR: 0.591,95% CI: 0.359, 0.970, P = 0.038) than in those younger than 25 years. The only association between prevalence of symptoms and tobacco use and SHS exposure was that smokers had a lower occurrence of phlegm in the throat(OR: 0.579, 95% CI: 0.392,0.856, P = 0.006). Shortness of breath was less frequent in participants exposed to moxa smoke for more than 5 years(5-10 years: OR: 0.400, 95% CI:0.204, 0.785, P = 0.008; 11-20 years: OR: 0.392, 95%CI: 0.178, 0.864, P = 0.02), but a slightly higher incidence of eye itchiness was found in those with over20 years of moxa exposure(OR: 4.200, 95% CI:1.344, 3.128, P = 0.014).CONCLUSION: The most frequent symptom of moxa smoke exposure in acupuncturists was tear-ing. The association of symptoms with age and duration of exposure to moxa smoke were rather complicated; hence, care should be taken in drawing conclusions about the safety of moxa smoke based solely on its potentially harmful ingredients. | Wang Xiang Yu Chang Tang Yong Chang Shyang Yang Hui Zhang He Jiaozi Zhang Yueyue Jiao Yang Zhuang Zhiqi Yin Haiyan Zhang Chengshun Lu Peng Wu Qiaofeng Yu Shuguang | 2018 | Journal of Traditional Chinese Medicine2018，38，1： | 7 |
| 4 | Functional identification of the terpene synthase family involved in diterpenoid alkaloids biosynthesis in Aconitum carmichaelii显示文摘Aconitum carmichaelii is a high-value medicinal herb widely used across China,Japan,and other Asian countries.Aconitine-type diterpene alkaloids(DAs)are the characteristic compounds in Aconitum.Although six transcriptomes,based on short-read next generation sequencing technology,have been reported from the Aconitum species,the terpene synthase(TPS)corresponding to DAs biosynthesis remains unidentified.We apply a combination of Pacbio isoform sequencing and RNA sequencing to provide a comprehensive view of the A.carmichaelii transcriptome.Nineteen TPSs and five alternative splicing isoforms belonging to TPS-b,TPS-c,and TPS-e/f subfamilies were identified.In vitro enzyme reaction analysis functional identified two sesqui-TPSs and twelve di TPSs.Seven of the TPS-c subfamily genes reacted with GGPP to produce the intermediate ent-copalyl diphosphate.Five Ac KSLs separately reacted with ent-CPP to produce ent-kaurene,ent-atiserene,and ent-13-epi-sandaracopimaradie:a new diterpene found in Aconitum.Ac TPSs gene expression in conjunction DAs content analysis in different tissues validated that ent-CPP is the sole precursor to all DAs biosynthesis,with Ac KSL1,Ac KSL2 s and Ac KSL3-1 responsible for C20 atisine and napelline type DAs biosynthesis,respectively.These data clarified the molecular basis for the C20-DAs biosynthetic pathway in A.carmichaelii and pave the way for further exploration of C19-DAs biosynthesis in the Aconitum species. | Liuying Mao Baolong Jin Lingli Chen Mei Tian Rui Ma Biwei Yin Haiyan Zhang Juan Guo Jinfu Tang Tong Chen Changjiangsheng Lai Guanghong Cui Luqi Huang | 2021 | Acta Pharmaceutica Sinica B2021，11，10： | 6 |
| 5 | Hydrothermal alteration of plagioclase microphenocrysts and glass in basalts from the East Pacific Rise near 13°N: An SEM-EDS study显示文摘The interactions of seafloor hydrothermal fluid with igneous rocks can result in leaching elements from the rocks,creating potential ore-forming fluids and influencing the chemical compositions of near-bottom seawater.The hydrothermal alteration of plagioclase microphenocrysts and basaltic glass in the pillow basalts from one dredge station(103°57.62′′W,12°50.55′N,water depth 2480 m)on the East Pacific Rise(EPR)near 13°N were analyzed using a scanning electron microscope(SEM)and energy dispersive X-ray spectrometry(EDS).The results show that the edges of the plagioclase microphenocrysts and the basaltic glass fragments are altered but the pyroxene and olivine microphenocrysts in the interior of the pillow basalts appear to be unaffected by the hydrothermal fluids.In addition,our results show that the chemical alteration at the rims of the plagioclase microphenocrysts and the edges of basaltic glass fragments can be divided into separate types of alteration.The chemical difference in hydrothermal alteration of the plagioclase microphenocrysts and the basaltic glass indicate that different degrees of hydrothermal fluid-solid phase interaction have taken place at the surface of the pillow basalts.If the degree of hydrothermal fluid-solid phase interaction is relatively minor,Si,Al,Ca and Na diffuse from the inside of the solid phase out and as a result these elements have a tendency to accumulate in the edge of the plagioclase microphenocrysts or basaltic glass.If the degree of hydrothermal fluid-solid phase interaction is relatively strong,Si,Al,Ca and Na also diffuse from the inside of solid phase out but these elements will have a relatively low concentration in the edge of the plagioclase microphenocrysts or basaltic glass.Based on the chemical variation observed in the edges of plagioclase microphenocrysts and basaltic glass,we estimate that the content of Si,Al and Fe in the edges of plagioclase microphenocrysts can have a variation of 10.69%,17.59%and 109%,respectively.Similarly,the Si,Al and Fe concentrations in the edges of basaltic glass can have a variation of 9.79%,16.30%and 37.83%,respectively,during the interaction of hydrothermal fluids and seafloor pillow basalt. | ZENG ZhiGang QI HaiYan CHEN Shuai YIN XueBo LI ZhaoXue | 2014 | Science China Earth Sciences2014，57，7： | 5 |
| 6 | Synchrotron radiation-based Fourier-transform infrared spectromicroscopy for characterization of the protein/peptide distribution in single microspheres显示文摘The present study establishes a visualization method for the measurement of the distribution and localization of protein/peptide constituents within a single poly-lactide-co-glycolide(PLGA) microsphere using synchrotron radiation–based Fourier-transform infrared spectromicroscopy(SR-FTIR).The representative infrared wavenumbers specific for protein/peptide(Exenatide) and excipient(PLGA) were identified and chemical maps at the single microsphere level were generated by measuring and plotting the intensity of these specific bands.For quantitative analysis of the distribution within microspheres,Matlab software was used to transform the map file into a 3D matrix and the matrix values specific for the drug and excipient were extracted.Comparison of the normalized SR-FTIR maps of PLGA and Exenatide indicated that PLGA was uniformly distributed,while Exenatide was relatively non-uniformly distributed in the microspheres.In conclusion,SR-FTIR is a rapid,nondestructive and sensitive detection technology to provide the distribution of chemical constituents and functional groups in microparticles and microspheres. | Manli Wang Xiaolong Lu Xianzhen Yin Yajun Tong Weiwei Peng Li Wu Haiyan Li Yan Yang Jingkai Gu Tiqiao Xiao Min Chen Jiwen Zhang | 2015 | Acta Pharmaceutica Sinica B2015，5，3： | 5 |
| 7 | Fe-Si-Mn-Oxyhydroxide Encrustations on Basalts at East Pacific Rise near 13°N:An SEM-EDS Study显示文摘Fe-Si-Mn-oxyhydroxide encrustations at the East Pacific Rise(EPR) near 13°N were analyzed using the scanning electron microscope(SEM) with an energy dispersive spectrometer(EDS). These encrustations are mainly composed of amorphous FeSi-Mn-oxyhydroxides forming laminated, spherical, porous aggregates with some biodetritus, anhydrite, nontronite, and feldspar particles. Anhydrite particles and nontronite crystals in the Fe-Si-Mn-oxyhydroxide encrustations imply that the Fe-Si-Mn- oxyhydroxide may have formed under relatively low- to high-temperature hydrothermal conditions. The Fe-Si-Mn-oxyhydroxide encrustations on pillow basalts are 1–2 mm thick. The growth rate of ferromanganese crusts in the survey area suggests that these encrustations are an unlikely result of hydrogenic deposition alone having a hydrothermal and(Fe/Mn ratio up to 7.7 and Fe/(Fe+Mn+Al) ratio exceeding 0.78) hydrogenic origin(0.22 Fe/Mn ratio close to the mean value of 0.7 for open-ocean seamount crusts). The varying Fe/Mn ratios indicate that the Fe-Si-Mn-oxyhydroxide encrustations have formed through several stages of seafloor hydrothermalism. It is suggested that, at the initial formation stage, dense Fe-Si-oxyhydroxides with low Mn content deposit from a relatively reducing hydrothermal fluid, and then the loose Fe-Si-Mn-oxyhydroxides deposit on the Fe-Si-oxyhydroxides. As the oxidation degree of hydrothermal fluid increases and Si-oxide is inhibited, Mn-oxide will precipitate with Fe-oxyhydroxides. | WANG Xiaoyuan ZENG Zhigang QI Haiyan CHEN Shuai YIN Xuebo YANG Baoju | 2014 | Journal of Ocean University of China2014，13，6： | 5 |

| 9 | Cisplatin-induced vestibular hair cell lesion-less damage at high doses显示文摘Cisplatin, a widely used anticancer drug, damages hair cells in cochlear organotypic cultures at low doses, but paradoxically causes little damage at high doses resulting in a U-shaped dose-response function. To determine if the cisplatin dose-response function for vestibular hair cells follows a similar pattern, we treated vestibular organotypic cultures with doses of cisplatin ranging from 10 to 1000 μM. Vestibular hair cell lesions progressively increased as the dose of cisplatin increased with maximum damage occurring around 50-100 μM, but the lesions progressively decreased at higher doses resulting in little hair cell loss at 1000 μM. The U-shaped doseresponse function for cisplatin-treated vestibular hair cells in culture appears to be regulated by copper transporters, Ctrl, ATP7A and ATP7B, that dose-dependently regulate the uptake, sequestration and extrusion of cisplatin. | Dalian Ding Haiyan Jiang Jianhui Zhang Xianrong Xu Weidong Qi Haibo Shi Shankai Yin Richard Salvi | 2018 | Journal of Otology2018，13，4： | 4 |
| 10 | Synthesis of taurine-fluorescein conjugate and evaluation of its retina-targeted efficiency in vitro显示文摘In this work, retinal penetration of fluorescein was achieved in vitro by covalent attachment of taurine to fluorescein, yielding the F-Tau conjugate. Nuclear magnetic resonance (NMR) and high resolution mass spectrometry (HRMS) were used to confirm the successful synthesis of F-Tau. The cellular uptake of F-Tau in adult retinal pigment epithelial cells (ARPE-19) and human retinal microvascular endothelial cells (hRMECs) was visualized via confocal scanning microscopy. The results indicated an improvement of solubility and a reduction of logP of F-Tau compared with fluorescein. As compared with fluorescein, F-Tau showed little toxicity, and was retained longer by cells in uptake experiments. F-Tau also displayed higher transepithelial permeabilities than fluorescein in ARPE-19 and hRMECs monolayer cells (Po0.05). These results showed that taurine may be a useful ligand for targeting small-molecule hydrophobic pharmaceuticals into the retina. | Meihong Huang Jiaqi Song Bingzheng Lu Huizhi Huang Yizhen Chen Wei Yin Wenbo Zhu Xinwen Su Chuanbin Wu Haiyan Hu | 2014 | Acta Pharmaceutica Sinica B2014，4，6： | 4 |
| 11 | An infrastructure with user-centered presentation data model for integrated management of materials data and services显示文摘With scientific research in materials science becoming more data intensive and collaborative after the announcement of the Materials Genome Initiative,the need for modern data infrastructures that facilitate the sharing of materials data and analysis tools is compelling in the materials community.In this paper,we describe the challenges of developing such infrastructure and introduce an emerging architecture with high usability.We call this architecture the Materials Genome Engineering Databases(MGED).MGED provides cloud-hosted services with features to simplify the process of collecting datasets from diverse data providers,unify data representation forms with user-centered presentation data model,and accelerate data discovery with advanced search capabilities.MGED also provides a standard service management framework to enable finding and sharing of tools for analyzing and processing data.We describe MGED’s design,current status,and how MGED supports integrated management of shared data and services. | Shilong Liu Yanjing Su Haiqing Yin Dawei Zhang Jie He Haiyou Huang Xue Jiang Xuan Wang Haiyan Gong Zhuang Li Hao Xiu Jiawang Wan Xiaotong Zhang | 2021 | npj Computational Materials2021，，1： | 4 |
| 12 | High-resolution mapping of brain vasculature and its impairment in the hippocampus of Alzheimer’s disease mice显示文摘Accumulating evidence indicates the critical importance of cerebrovascular dysfunction in the pathogenesis of Alzheimer’s disease(AD).However,systematic comparative studies on the precise brain vasculature of wild-type and AD model mice are still rare.Using an image-optimization method for analysing Micro-Optical Sectioning Tomography(MOST)data,we generated cross-scale whole-brain 3 D atlases that cover the entire vascular system from large vessels down to smallest capillaries at submicron resolution,for both wild-type mice and a transgenic(APP/PS1)mouse model of AD.In addition to distinct vascular patterns in different brain regions,we found that the main vessels of the molecular layer of the hippocampal dentate gyrus(DG-ml)undergo abrupt changes in both diameter and branch angle,spreading a unique comb-like pattern of capillaries.By using a quantitative analysis workflow,we identified in the hippocampus of AD mice an overall reduction of the mean vascular diameter,volume fraction and branch angle,with most significant impairment in the DG-ml.In addition,virtual endoscopy revealed irregular morphological features in the vessel lumen of the AD mice,potentially contributing to the impairment of blood flow.Our results demonstrate the capability of high-resolution cross-scale evaluation of brain vasculature and underscore the importance of studying hippocampal microcirculation for understanding AD pathogenesis. | Xiaochuan Zhang Xianzhen Yin Jingjing Zhang Anan Li Hui Gong Qingming Luo Haiyan Zhang Zhaobing Gao Hualiang Jiang | 2019 | National Science Review2019，6，6： | 4 |
| 13 | Chinese herbal medicine compound Yi-Zhi-Hao pellet inhibits replication of influenza virus infection through activation of heme oxygenase-1显示文摘As a leading cause of respiratory disease, influenza A virus(IAV) presents a pandemic threat in annual seasonal outbreaks. Given the limitation of existing anti-influenza therapies, there remains to be a requirement for new drugs. Compound Yi-Zhi-Hao pellet(CYZH) is a famous traditional Chinese medicine(TCM) used in the clinic, whose formula has been recorded in Complication of National Standard for Traditional Chinese Medicine to treat common cold. In this study, we found that CYZH exhibited a broad-spectrum anti-influenza activity and inhibited the expression of viral RNA and proteins in vitro. Mechanistically, CYZH had no inhibitory activities against viral protein hemagglutinin and IAV RNA-dependent RNA polymerase. Instead, it induced activation of erythroid 2-related factor 2(Nrf2) and nuclear factor kappa B(NF-κB), which subsequently upregulated heme oxygenase-1(HO-1) expression.Also, CYZH protected cells from oxidative damage induced by reactive oxygen series. In conclusions,CYZH inhibits IAV replication in vitro, at least partly by activating expression of the Nrf2/HO-1 pathway. | Jinqiu Yin Linlin Ma Huiqiang Wang Haiyan Yan Jin Hu Wen Jiang Yuhuan Li | 2017 | Acta Pharmaceutica Sinica B2017，7，6： | 4 |
| 14 | Smectite formation in metalliferous sediments near the East Pacific Rise at 13°N显示文摘A 43 cm long E271 sediment core collected near the East Pacific Rise(EPR) at 13°N were studied to investigate the origin of smectite for understanding better the geochemical behavior of hydrothermal material after deposition.E271 sediments are typical metalliferous sediments. After removal of organic matter, carbonate, biogenic opal,and Fe-Mn oxide by a series of chemical procedures, clay minerals(<2 μm) were investigated by X-ray diffraction,chemical analysis and Si isotope analysis. Due to the influence of seafloor hydrothermal activity and close to continent, the sources of clay minerals are complex. Illite, chlorite and kaolinite are suggested to be transported from either North or Central America by rivers or winds, but smectite is authigenic. It is enriched in iron, and its contents are highest in clay minerals. Data show that smectite is most likely formed by the reaction of hydrothermal Fe-oxyhydroxide with silica and seawater in metalliferous sediments. The Si that participates in this reaction may be derived from siliceous microfossils(diatoms or radiolarians), hydrothermal fluids, or detrital mineral phases. And their δ30 Si values are higher than those of authigenic smectites, which implies that a Si isotope fractionation occurs during the formation because of the selective absorption of light Si isotopes onto Feoxyhydroxides. Sm/Fe mass ratios(a proxy for overall REE/Fe ratio) in E271 clay minerals are lower than those in metalliferous sediments, as well as distal hydrothermal plume particles and terrigenous clay minerals. This result suggests that some REE are lost during the smectite formation, perhaps because their large ionic radii of REE scavenged by Fe-oxyhydroxides preclude substitution in either tetrahedral or octahedral lattice sites of this mineral structure, which decreases the value of metalliferous sediments as a potential resource for REE. | RONG Kunbo ZENG Zhigang YIN Xuebo CHEN Shuai WANG Xiaoyuan QI Haiyan MA Yao | 2018 | Acta Oceanologica Sinica2018，37，9： | 4 |
| 15 | Variation of reactivity of particulate and sedimentary organic matter along the Zhujiang River Estuary显示文摘To investigate organic matter source and reactivity in the Zhujiang River (Pearl River)Estuary and its adjacent areas, particulate organic carbon (POC), particulate hydrolysable amino acids (PHAA), and Chl a during two cruises in July 1999 and July 2000 were measured. The highest POC and PHAA concentration was observed in the waters with maximum Chl a.The spectra distribution, relative content (dry weight in milligram per gram), PHAA-C%POC and other indicators such as the ratios of amino acids vs. amino sugars (AA/AS)and glucosamine vs. galactosamine (Glum/Gal)suggested that particulate amino acids in the water column and sediments in the Zhujiang River Estuary were mainly derived from biogenic processes rather than transported from terrestrial erosion. In inner estuary where high turbidity was often observable, organic matter was mainly contributed by re-suspension of bottom sediments with revealed zooplankton, microbial reworked characteristics,which suggest that these organic matters were relatively 'old'. In the estuarine brackish region, organic matter in water column is mainly contributed by relatively fresh, easily degradable phytoplankton derived organic matter. During physical-biological processes within the eastuary, organic matter derived from phytoplankton was subjected to alteration by zooplankton grazing and bacterial reworking. | Chen Jianfang 1,2, Jin Haiyan 1,2, Yin Kedong3, Li Yan 1,2 1.

| 16 | Effects of quenching temperature on microstructure and mechanical properties of H13 mandrel steel显示文摘Optical microscope,stereomicroscope,scanning electronic microscope (SEM) and mechanical property testing were used to research the effects of different quenching temperatures on the microstructure and mechanical properties of the H13 mandrel steel.The results indicate that following an increase in the quenching,the degree of alloying is enhanced due to the carbides dissolving gradually in austenite,which improves the hardenability of the specimens,as well as their room and high-temperature strength.At the same time,the fracture toughness increases due to the increment of the martensite number and the interparticle distance of the carbides.However,extremely coarse grain and martensite can decrease the impact toughness.Optimal performance can be obtained after quenching at 1060℃ and double tempering at 620℃.Consequently,the service life of the H13 mandrel steel is extended significantly. | TIAN Yuxin LU Minghe CAI Haiyan YIN Guanghong XU Zhou | 2010 | Baosteel Technical Research2010，4，3： | 3 |

| 19 | Antioxidative stress-induced damage in cochlear explants显示文摘The imbalance of reactive oxygen species and antioxidants is considered to be an important factor in the cellular injury of the inner ear. At present, great attention has been placed on oxidative stress. However,little is known about fighting oxidative stress. In the current study, we evaluated antioxidant-induced cochlear damage by applying several different additional antioxidants. To determine whether excessive antioxidants can cause damage to cochlear cells, we treated cochlear explants with 50 m M M40403, a superoxide dismutase mimetic, 50 m M coenzyme Q-10, a vitamin-like antioxidant, or 50 m M d-methionine, an essential amino acid and the important antioxidant glutathione for 48 h. Control cochlear explants without the antioxidant treatment maintained their normal structures after incubation in the standard serum-free medium for 48 h, indicating the maintenance of the inherent oxidative and antioxidant balance in these cochlear explants. In contrast, M40403 and coenzyme Q-10-treated cochlear explants displayed significant hair cell damage together with slight damage to the auditory nerve fibers.Moreover, d-methiodine-treated explants exhibited severe damage to the surface structure of hair cells and the complete loss of the spiral ganglion neurons and their peripheral fibers. These results indicate that excessive antioxidants are detrimental to cochlear cells, suggesting that inappropriate dosages of antioxidant treatments can interrupt the balance of the inherent oxidative and antioxidant capacity in the cell. | Dalian Ding Jianghui Zhang Fang Liu Peng Li Weidong Qi Yazhi Xing Haibo Shi Haiyan Jiang Hong Sun Shankai Yin Richard Salvi | 2020 | Journal of Otology2020，15，1： | 3 |
| 20 | Possibility of women treated with fertility-sparing surgery fornon-epithelial ovarian tumors to safely and successfully becomepregnant--a Chinese retrospective cohort study among 148cases显示文摘This study was performed to evaluate the oncological and reproductive outcomes of childbearing-agewomen treated with fertility-sparing surgery (FSS) for non-epithelial ovarian tumors in China. One hundred andforty eight non-epithelial ovarian tumor women treated with FSS between January I, 2000 and August 31, 2015from two medical centers in China were identified. Progression-free survival (PFS) was 88.5%, whereas overallsurvival (OS) was 93.9%. Univariate analysis suggested that delivery after treatment is related to PFS (P = 0.023),whereas histology significantly influenced OS. Cox regression analysis suggested that only histology was associatedwith PFS and OS (P 〈 0.05). Among the 129 women who completed adjuvant chemotherapy (ACT), nonedeveloped amenorrhea. Among the 44 women who desired pregnancy, 35 (79.5%) successfully had 51 gestationsincluding 35 live births without birth defects. Non-epithelial ovarian tumors can achieve fulfilling prognosis afterFSS and chemotherapy. Histology might be the only independent prognostic factor for PFS and OS. FSS followedby ACT appeared to have little or no effect on fertility. Meanwhile, postoperative pregnancy did not increase thePFS or OS. Use of gonadotropin-releasing hormone agonist was not beneficial for fertility. | Bin Yang Yan Yu Jing Chen Yan Zhang Ye Yin Nan Yu Ge Chen Shifei Zhu Haiyan Huang Yongqun Yuan Jihui Ai Xinyu Wang Kezhen Li | 2018 | Frontiers of Medicine2018，12，5： | 3 |
