| 1 | Comparison of Undernutrition Prevalence of Children under 5 Years in China between 2002 and 2013显示文摘Objective To describe the undernutrition status of children under 5-year in China, and study the trend between 2002 and 2013. Methods The study was based on two national surveys. Undernutrition was determined against WHO's 2006 growth standards. The prevalence in 2013 and 2002 was weighted by China sixth National Population Census(2010). The relationship between undernutrition and gender/age groups/different areas use weighted logistic regression. Results The results indicated the overall prevalence of stunting, underweight, and wasting of Chinese children under 5-year was 8.1%, 2.4%, and 1.9% in 2013, respectively. The prevalence of stunting was higher for children aged 12-47 month, while underweight was higher for children aged 48-59 month. The prevalence of undernutrition was higher in rural areas than in urban areas, especially in poor rural areas. There was a decline of stunting, underweight, and wasting between 2002 and 2013 among the children, with greater reduction in rural areas than in urban areas. Conclusion The prevalence of undernutrition of children under 5-year remains high in rural areas especially in poor rural areas in China. It is urgent to take action to control undernutrition in the vulnerable areas and subgroups. | YU Dong Mei ZHAO Li Yun YANG Zhen Yu CHANG Su Ying YU Wen Tao FANG Hong Yun WANG Xun YU Dan GUO Qi Ya XU Xiao Li FANG Yue Hui ZHAO Wen Hua YANG Xiao Guang DING Gang Qiang LIANG Xiao Feng | 2016 | Biomedical and Environmental Sciences2016，29，3： | 18 |
| 2 | Exploring an Integrative Therapy for Treating COVID-19:A Randomized Controlled Trial显示文摘Objectives:To develop a new Chinese medicine(CM)-based drug and to evaluate its safety and effect for suppressing acute respiratory distress syndrome(ARDS)in COVID-19 patients.Methods:A putative ARDS-suppressing drug Keguan-1 was first developed and then evaluated by a randomized,controlled two-arm trial.The two arms of the trial consist of a control therapy(alpha interferon inhalation,50(x g twice daily;and lopinavir/ritonavir,400 and 100 mg twice daily,respectively)and a testing therapy(control therapy plus Keguan-119.4 g twice daily)by random number table at 1:1 ratio with 24 cases each group.After 2-week treatment,adverse events,time to fever resolution,ARDS development,and lung injury on newly diagnosed COVID-19 patients were assessed.Results:An analysis of the data from the first 30 participants showed that the control arm and the testing arm did not exhibit any significant differences in terms of adverse events.Based on this result,the study was expanded to include a total of 48 participants(24 cases each arm).The results show that compared with the control arm,the testing arm exhibited a significant improvement in time to fever resolution(P=0.035),and a significant reduction in the development of ARDS(P=0.048).Conclusions:Keguan-1-based integrative therapy was safe and superior to the standard therapy in suppressing the development of ARDS in COVID-19 patients.(Trial registration No.NCT 04251871 at www.clinicaltrials.gov). | WANG Jia-bo WANG Zhong-xia JING Jing ZHAO Peng DONG Jing-hui ZHOU Yong-feng YANG Guang NIU Ming ZHAO Xu JIANG Tian-jun Bl Jing-feng XU Zhe ZHANG Ping WU Dan BAI Zhao-fang GUO Yu-ming YU Si-miao SUN Yong-qiang ZHANG Zi-teng ZHAN Xiao-yan LI Peng-yan DING Jin-biao ZHAO Peng-fei SONG Xue-ai TANG Jian-yuan HE Dong-chu CHEN Zhu QIN En-qiang WANG Rui-lin XIAO Xiao-he | 2020 | Chinese Journal of Integrative Medicine2020，26，9： | 18 |
| 3 | One-year clinical study of NeuroR egen scaffold implantation following scar resection in complete chronic spinal cord injury patients显示文摘The objective of this clinical study was to assess the safety and feasibility of the collagen scaffold, Neuro Regen scaffold, one year after scar tissue resection and implantation. Scar tissue is a physical and chemical barrier that prevents neural regeneration. However, identification of scar tissue is still a major challenge. In this study, the nerve electrophysiology method was used to distinguish scar tissue from normal neural tissue, and then different lengths of scars ranging from 0.5–4.5 cm were surgically resected in five complete chronic spinal cord injury(SCI) patients. The NeuroR egen scaffold along with autologous bone marrow mononuclear cells(BMMCs), which have been proven to promote neural regeneration and SCI recovery in animal models, were transplanted into the gap in the spinal cord following scar tissue resection. No obvious adverse effects related to scar resection or Neuro Regen scaffold transplantation were observed immediately after surgery or at the 12-month follow-up. In addition, patients showed partially autonomic nervous function improvement, and the recovery of somatosensory evoked potentials(SSEP) from the lower limbs was also detected. The results indicate that scar resection and Neuro Regen scaffold transplantation could be a promising clinical approach to treating SCI. | Zhifeng Xiao Fengwu Tang Jiaguang Tang Huilin Yang Yannan Zhao Bing Chen Sufang Han Nuo Wang Xing Li Shixiang Cheng Guang Han Changyu Zhao Xiaoxiong Yang Yumei Chen Qin Shi Shuxun Hou Sai Zhang Jianwu Dai | 2016 | Science China(Life Sciences)2016，59，7： | 18 |
| 4 | Effectiveness of Different Waist Circumference Cut-off Values in Predicting Metabolic Syndrome Prevalence and Risk Factors in Adults in China显示文摘Objective To study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome(MetS) and risk factors in adults in China. Methods A cross-sectional survey was condcuted in 14 provinces(autonomous region, municipality) in China. A total of 47 325 adults aged ≥20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation(IDF) criteria and modified IDF criteria.Results The age-standardized prevalence of MetS was 24.2%(22.1% in men and 25.8% in women) and 19.5%(22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1%(8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity(90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China. | ZHOU Hai Cheng LAI Ya Xin SHAN Zhong Yan JIA Wei Ping YANG Wen Ying LU Ju Ming WENG Jian Ping JI Li Nong LIU Jie TIAN Hao Ming JI Qiu He ZHU Da Long CHEN Li GUO Xiao Hui ZHAO Zhi Gang Li Qiang ZHOU Zhi Guang GE Jia Pu SHAN Guang Liang | 2014 | Biomedical and Environmental Sciences2014，27，5： | 17 |
| 5 | Essential oil of Curcuma wenyujin induces apoptosis in human hepatoma cells显示文摘AIM: To investigate the effects of the essential oil of Curcuma wenyujin (CWO) on growth inhibition and on the induction of apoptosis in human HepG2 cancer cells. METHODS: The cytotoxic effect of drugs on HepG2 cells was measured by 3-(4,5-dimethylthiazol-2- yl)-2,5-diphenyltetra-zolium bromide (MTT) assay. DNA fragmentation was visualized by agarose gel electrophoresis. Cell cycle and mitochondrial transmembrane potential (△Ψm) were determined by flow cytometry (FCM). Cytochrome C immunostaining was evaluated by fluorescence microscopy. Caspase-3 enzymatic activity was assayed by the cleavage of Ac-DEVD-R110. Cleaved PARP and active caspase-3 protein levels were measured by FCM using BD? CBA Human Apoptosis Kit. RESULTS: Treatment with CWO inhibited the growth of HepG2 cells in a dose-dependent manner, and the IC50 of CWO was approximately 70 μg/mL. CWO was found to inhibit the growth of HepG2 cells by inducing a cell cycle arrest at S/G2. DNA fragmentation was evidentlyobserved at 70 μg/mL after 72 h of treatment. During the process, cytosolic HepG2 cytochrome C staining showed a markedly stronger green fluorescence than in control cells in a dose-dependent fashion, and CWO also caused mitochondrial transmembrane depolarization. Furthermore, the results clearly demonstrated that both, activity of caspase-3 enzyme and protein levels of cleaved PARP, significantly increased in a dose- dependent manner after treatment with CWO. CONCLUSION: CWO exhibits an antiproliferative effect in HepG2 cells by inducing apoptosis. This growth inhibition is associated with cell cycle arrest, cytochrome C translocation, caspase 3 activation, Poly- ADP-ribose polymerase (PARP) degradation, and loss of mitochondrial membrane potential. This process involves a mitochondria-caspase dependent apoptosis pathway. As apoptosis is an important anti-cancer therapeutic target, these results suggest a potential of CWO as a chemotherapeutic agent. | YU Xiao Feng-Qing Yang Shao-Ping Li Guang Hu Simon Ming-Yuen Lee Yi-Tao Wang | 2008 | World Journal of Gastroenterology2008，14，27： | 13 |
| 6 | The Impacts of Mosquito Density and Meteorological Factors on Dengue Fever Epidemics in Guangzhou, China, 2006-2014: a Time-series Analysis显示文摘Objective To explore the associations between the monthly number of dengue fever(DF) cases and possible risk factors in Guangzhou, a subtropical city of China. Methods The monthly number of DF cases, Breteau Index(BI), and meteorological measures during 2006-2014 recorded in Guangzhou, China, were assessed. A negative binomial regression model was used to evaluate the relationships between BI, meteorological factors, and the monthly number of DF cases. Results A total of 39,697 DF cases were detected in Guangzhou during the study period. DF incidence presented an obvious seasonal pattern, with most cases occurring from June to November. The current month's BI, average temperature(Tave), previous month's minimum temperature(Tmin), and Tave were positively associated with DF incidence. A threshold of 18.25 °C was found in the relationship between the current month's Tmin and DF incidence. Conclusion Mosquito density, Tave, and Tmin play a critical role in DF transmission in Guangzhou. These findings could be useful in the development of a DF early warning system and assist in effective control and prevention strategies in the DF epidemic. | SHEN Ji Chuan LUO Lei LI Li JING Qin Long OU Chun Quan YANG Zhi Cong CHEN Xiao Guang | 2015 | Biomedical and Environmental Sciences2015，28，5： | 12 |
| 7 | High quality reference genome of drumstick tree(Moringa oleifera Lam.), a potential perennial crop显示文摘The drumstick tree(Moringa oleifera Lam.) is a perennial crop that has gained popularity in certain developing countries for its high-nutrition content and adaptability to arid and semi-arid environments. Here we report a high-quality draft genome sequence of M. oleifera. This assembly represents 91.78% of the estimated genome size and contains 19,465 protein-coding genes. Comparative genomic analysis between M. oleifera and related woody plant genomes helps clarify the general evolution of this species, while the identification of several species-specific gene families and positively selected genes in M. oleifera may help identify genes related to M. oleifera's high protein content, fast-growth, heat and stress tolerance. This reference genome greatly extends the basic research on M. oleifera, and may further promote applying genomics to enhanced breeding and improvement of M. oleifera. | TIAN Yang ZENG Yan ZHANG Jing YANG Cheng Guang YAN Liang WANG XuanJun SHI ChongYing XIE Jing DAI TianYi PENG Lei ZENG HUAN Yu XU An Ni HUANG YeWei ZHANG JiaJin MA Xiao DONG Yang HAO ShuMei SHENG Jun | 2015 | Science China(Life Sciences)2015，58，7： | 10 |
| 8 | Qinggan Huoxue Recipe suppresses epithelial-tomesenchymal transition in alcoholic liver fibrosis through TGF-β1/Smad signaling pathway显示文摘AIM: To investigate the mechanism by which Qinggan Huoxue Recipe(QGHXR) inhibits epithelial-to-mesenchymal transition(EMT) in rats with alcoholic liver fibrosis(ALF).METHODS: A total of 75 male SD rats were used to induce ALF. Serum biochemical indicators, includingalanine aminotransferase, aspartate aminotransferase, laminin and hyaluronidase, were measured. Liver histopathological changes were evaluated using hematoxylineosin and Sirius red staining. EMT was examined by analyzing the expression of the epithelial marker E-cadherin and the mesenchymal markers vimentin and fibronectin using RT-PCR and Western blot. The inhibitory effect of QGHXR on EMT markers, as well as its effect on molecules associated with the transforming growth factor(TGF)-β1/Smad signaling pathway, including TGF-β1, Smad3, snail, occludin, ZO-1 and claudin, was also examined.RESULTS: Compared with normal control rats, ALF rats exhibited a decrease in E-cadherin levels(m RNA: ALF 0.16 ± 0.05 vs control 1.00 ± 0.08; protein: ALF 0.09 ± 0.05 vs control 0.70 ± 0.17, P < 0.01) and an increase in vimentin and fibronectin levels(m RNA: 11.43 ± 0.39 vs 1.00 ± 0.19 and 9.91 ± 0.34 vs 1.00 ± 0.44, respectively, P < 0.01; protein: 1.13 ± 0.42 vs 0.09 ± 0.03 and 1.16 ± 0.43 vs 0.09 ± 0.00, respectively, P < 0.01). This indicates that EMT occurred in ALF rats. In addition, the TGF-β1/Smad signaling pathway was activated in ALF rats, as evidenced by the increase in TGF-β1 and snail levels(m RNA: 1.76 ± 0.12 vs 1.00 ± 0.05 and 6.98 ± 0.41 vs 1.00 ± 0.10, respectively, P < 0.01; protein: 1.43 ± 0.05 vs 0.12 ± 0.03 and 1.07 ± 0.29 vs 0.07 ± 0.02, respectively, P < 0.01) and the decrease in Smad3 levels(m RNA: 0.05 ± 0.01 vs 1.00 ± 0.12, P < 0.01; protein: 0.06 ± 0.05 vs 0.89 ± 0.12, P < 0.01). Furthermore, levels of the tight junction markers occludin, ZO-1 and claudin decreased in ALF rats compared with healthy control rats(m RNA: 0.60 ± 0.09 vs 1.00 ± 0.12, 0.11 ± 0.00 vs 1.00 ± 0.12 and 0.60 ± 0.01 vs 1.00 ± 0.08, respectively, P < 0.01; protein: 0.05 ± 0.01 vs 0.87 ± 0.40, 0.09 ± 0.05 vs 0.89 ± 0.18 and 0.04 ± 0.03 vs 0.95 ± 0.21, respectively, P < 0.01). In ALF rats treated with QGHXR, E-cadherin levels increased(m RNA: QGHXR 0.67 ± 0.04 vs ALF model 0.16 ± 0.05, P < 0.01; protein: QGHXR 0.66 ± 0.21 vs ALF model 0.09 ± 0.05, P < 0.01), and vimentin and fibronectin levels decreased(m RNA: 6.57 ± 1.05 vs 11.43 ± 0.39 and 1.45 ± 1.51 vs 9.91 ± 0.34, respectively, P < 0.01; protein: 0.09 ± 0.03 vs 1.13 ± 0.42 and 0.10 ± 0.01 vs 1.16 ± 0.43, respectively, P < 0.01). In addition, QGHXR inhibited the expression of TGF-β1 and increased the expression of Smad3(m RNA: 1.03 ± 0.11 vs 1.76 ± 0.12, 0.70 ± 0.10 vs 0.05 ± 0.01, respectively, P < 0.05 and P < 0.01; protein: 0.12 ± 0.03 vs 1.43 ± 0.05 and 0.88 ± 0.20 vs 0.06 ± 0.05, respectively, P < 0.01). QGHXR treatment also reduced the levels of the EMT-inducing transcription factor snail(m RNA: 2.28 ± 0.33 vs 6.98 ± 0.41, P < 0.01; protein: 0.08 ± 0.02 vs 1.07 ± 0.29, P < 0.01) and increased the occludin, ZO-1 and claudin levels(m RNA: 0.73 ± 0.05 vs 0.60 ± 0.09, 0.57 ± 0.04 vs 0.11 ± 0.00 and 0.68 ± 0.03 vs 0.60 ± 0.01, respectively, P < 0.01, P < 0.01 and P < 0.05; protein: 0.92 ± 0.50 vs 0.05 ± 0.01, 0.94 ± 0.22 vs 0.09 ± 0.05 and 0.94 ± 0.29 vs 0.04 ± 0.03, respectively, P < 0.01). The effects of QGR and HXR on the TGF-β1/Smad signaling pathway weresimilar to that of QGHXR; however, the QGR- and HXRinduced changes in vimentin m RNA levels, the QGRinduced changes in fibronectin m RNA levels and the HXR-induced changes in snail and TGF-β1 m RNA levels were not significant.CONCLUSION: Qinggan Huoxue Recipe inhibits EMT in ALF rats by modulating the TGF-β1/Smad signaling pathway, suggesting that the mechanism underlying the amelioration of ALF induced by QGHXR is associated with this pathway. | Tao Wu Jun-Ming Chen Tie-Gang Xiao Xiang-Bing Shu Han-Chen Xu Li-Li Yang Lian-Jun Xing Pei-Yong Zheng Guang Ji | 2016 | World Journal of Gastroenterology2016，22，19： | 8 |

| 11 | Effect on platelet aggregation activity: extracts from 31 Traditional Chinese Medicines with the property of activating blood and resolving stasis显示文摘OBJECTIVE: To evaluate the anti-platelet aggregation effects of extracts from 31 Traditional Chinese Medicines(TCM) with the property of activating blood and resolving stasis in terms of TCM theory.METHODS: The 31 TCMs extracts were prepared using water, 90% ethanol and ethyl acetate., and the effects on anti-platelet aggregation were tested on a platelet aggregation analyzer in vitro with adenosine 5'-diphosphate, bovine thrombin and arachi-donic acid(AA) as aggregation inducers, respectively. Aspirin was the positive control.RESULTS: Lots of the tested TCMs had inhibitory effects with concentration-dependent manner on platelet aggregations induced by various agonists.Especially, some of the TCMs such as Chuanxiong(Rhizoma Chuanxiong), Yanhusuo(Rhizoma Corydalis Yanhusuo) and Danshen(Radix Salviae Miltiorrhizae) showed good anti-platelet aggregation effect similar or higher than that in positive control group.CONCLUSION: The study provided scientific references that several TCMs such as Chuanxiong(Rhizoma Chuanxiong), Yanhusuo(Rhizoma Corydalis Yanhusuo) and Danshen(Radix Salviae Miltiorrhizae),possess the property of anti-platelet aggregation. | Chen Cen Wang Fengqin Xiao Wen Xia Zhining Hu Guang Wan Jianbo Yang Fengqing | 2017 | Journal of Traditional Chinese Medicine2017，37，1： | 7 |
| 12 | Immobilized thrombin on X-ray radiopaque polyvinyl alcohol/chitosan embolic microspheres for precise localization and topical blood coagulation显示文摘Trans-catheter arterial embolization(TAE)plays an important role in treating various diseases.The available embolic agents lack X-ray visibility and do not prevent the reflux phenomenon,thus hindering their application for TAE therapy.Herein,we aim to develop a multifunctional embolic agent that combines the X-ray radiopacity with local procoagulant activity.The barium sulfate nanoparticles(BaSO4 NPs)were synthesized and loaded into the polyvinyl alcohol/chitosan(PVA/CS)to prepare the radiopaque BaSO4/PVA/CS microspheres(MS).Thereafter,thrombin was immobilized onto the BaSO4/PVA/CS MS to obtain the thrombin@BaSO4/PVA/CS MS.The prepared BaSO4/PVA/CS MS were highly spherical with diameters ranging from 100 to 300μm.In vitro CT imaging showed increased X-ray visibility of BaSO4/PVA/CS MS with the increased content of BaSO4 NPs in the PVA/CS MS.The biocompatibility assessments demonstrated that the MS were non-cytotoxic and possessed permissible hemolysis rate.The biofunctionalized thrombin@BaSO4/PVA/CS MS showed improved hemostatic capacity and facilitated hemostasis in vitro.Additionally,in vivo study performed on a rabbit ear embolization model confirmed the excellent X-ray radiopaque stability of the BaSO4/PVA/CS MS.Moreover,both the BaSO4/PVA/CS and thrombin@BaSO4/PVA/CS MS achieved superior embolization effects with progressive ischemic necrosis on the ear tissue and induced prominent ultrastructural changes in the endothelial cells.The findings of this study suggest that the developed MS could act as a radiopaque and hemostatic embolic agent to improve the embolization efficiency. | Xiaohong Li Xiongfa Ji Kun Chen Muhammad Wajid Ullah Basen Li Jiameng Cao Lin Xiao Jun Xiao Guang Yang | 2021 | Bioactive Materials2021，6，7： | 6 |

| 14 | Application of UPLC-MS/MS Method for Analyzing B-vitamins in Human Milk显示文摘Objective To determine ten B-vitamins in human milk by ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS). Methods The pretreated human milk samples were adequately separated and quantified within 11 min by UPLC-MS/MS with an Acquity UPLC HSS T3 column(2.1×100 mm, 1.8 μm). The mobile phase was a gradient of 2.5 mmol/L ammonium formate aqueous solution and acetonitrile at a flow rate of 0.35 m L/min. Stable isotope internal standards were used in the analysis, to correct for the method variability, including matrix and ionization effects. The homogenized human milk samples were deproteinzed using methanol, unknown contaminants were extracted with diethyl ether and hydrophobic phase was discarded. The analytes were monitored via ESI+ionization and detected in multiple reaction monitoring(MRM) with three acquisition functions. Results Calibration curves ranged from 0.5-160 ng/m L(thiamin, riboflavin, biotin, nicotinic acid, pyridoxine, pyridoxamine, pyridoxal), and 2.5-800 ng/m L(pantothenic acid, FAD and nicotinamide)(R2=0.990-0.999). The relative recovery ranged from 80.1% to 120.2%; accuracy was determined to be 98.3% to 108.0%. Intra-day and inter-day variation were 3.4%-19.9% and 5.9%-18.1%, respectively. The limit of quantification(LOQ) for all vitamins was between 0.25 and 3 μg/L. Conclusion This method was successfully applied for simultaneous analysis of ten B-vitamins in human milk. | REN Xiang Nan YIN Shi An YANG Zhen Yu YANG Xiao Guang SHAO Bing REN Yi Ping ZHANG Jing | 2015 | Biomedical and Environmental Sciences2015，28，10： | 4 |
| 15 | Evaluation of tungsten interatomic potentials for radiation damage simulations显示文摘The structure and properties of materials under neutron irradiation are an important basis in future fusion reactors.In the absence of fusion neutron sources for irradiation experiments,it is increasingly important and urgent to carry out neutron irradiation simulations on fusion reactor materials and then establish complete databases of defect properties and collisional cascades,where the first and foremost step is to select suitable interatomic potentials for atomistic-level simulations.In this work,six typic interatomic potentials for tungsten(W)are evaluated and reviewed systematically for radiation damage simulations.The relative lattice stability and elastic constants of bulk W are considered first with those potentials;then,the properties of point defects and defect clusters at interstitial sites and vacancies are obtained by molecular statics/dynam-ics simulations.The formation energies of interstitial/vacancy clusters,1/2<111>and<100>dislocation loops in W and the threshold displacement energies along different directions are also determined.In addition,the extended defects are further investigated,such as free surfaces and the energy profiles of 1/2<111>{110}and 1/2<111>{112}stacking faults.The current results provide a reference for selecting W potentials to simulate the radiation damage. | Li‑Xia Liu Xiao‑Chun Li Yang‑Chun Chen Wang‑Yu Hu Guang‑Nan Luo Fei Gao Hui‑Qiu Deng | 2020 | Tungsten2020，2，1： | 4 |

| 17 | Size,morphology,and composition of lunar samples returned by Chang'E-5 mission显示文摘This study focuses on the physical and chemical properties of surficial lunar regolith(LR)samples returned from the Moon by the Chang’E-5(CE-5)mission.Insights regarding the effect of a new sampling geological site on the surficial lunar sample CE5 C0400 were illustrated using nondestructive techniques such as laser diffractometry coupled with image analysis,X-ray computed tomography,and field emission scanning electron microscopy equipped with energy dispersive spectroscopy,and Xray diffraction combined with Rietveld refinement.From the characterization analyses,the CE-5 sampling site in the northeastern Oceanus Procellarum on the Moon yields a unique collection of relatively regular-shaped and fine basalt-dominated particles.The median grain size D_(50) is(55.24±0.96)μm,falling within the relatively low end of the range of the Apollo lunar returned samples.The coefficient of uniformity C_(u)of 15.1 and the coefficient of curvature C_(c)of 1.7 could classify CE5 C0400 to be well-graded.The minerals in CE5 C0400 comprise approximately 44.5%pyroxene,30.4%plagioclase,3.6%olivine,and6.0%ilmenite.There is a relatively low content of approximately 15.5%glass phase in the CE-5 lunar sample.From the results,we deduce that the CE-5 LR structure could have mainly resulted from micrometeoroid impacts to achieve such a high level of maturity. | Hui Zhang Xian Zhang Guang Zhang Keqi Dong Xiangjin Deng Xiaosong Gao Yaodong Yang Yuan Xiao Xiao Bai Kaixin Liang Yiwei Liu Wenbin Ma Shaofan Zhao Ce Zhang Xiaojing Zhang Jian Song Wei Yao Hong Chen Weihua Wang Zhigang Zou Mengfei Yang | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，2： | 4 |
| 18 | Chinese expert consensus on conversion therapy for hepatocellular carcinoma(2021 edition)显示文摘Recent advances in systemic and locoregional treatments for patients with unresectable or advanced hepatocellular carcinoma(HCC)have resulted in improved response rates.This has provided an opportunity for selected patients with initially unresectable HCC to achieve adequate tumor downstaging to undergo surgical resection,a‘conversion therapy’strategy.However,conversion therapy is a new approach to the treatment of HCC and its practice and treatment protocols are still being developed.Review the evidence for conversion therapy in HCC and develop consensus statements to guide clinical practice.Evidence review:Many research centers in China have accumulated significant experience implementing HCC conversion therapy.Preliminary findings and data have shown that conversion therapy represents an important strategy to maximize the survival of selected patients with intermediate stage to advanced HCC;however,there are still many urgent clinical and scientific challenges for this therapeutic strategy and its related fields.In order to summarize and learn from past experience and review current challenges,the Chinese Expert Consensus on Conversion Therapy for Hepatocellular Carcinoma(2021 Edition)was developed based on a review of preliminary experience and clinical data from Chinese and non-Chinese studies in this field and combined with recommendations for clinical practice.Sixteen consensus statements on the implementation of conversion therapy for HCC were developed.The statements generated in this review are based on a review of clinical evidence and real clinical experience and will help guide future progress in conversion therapy for patients with HCC. | Hui-Chuan Sun Jian Zhou Zheng Wang Xiufeng Liu Qing Xie Weidong Jia Ming Zhao Xinyu Bi Gong Li Xueli Bai Yuan Ji Li Xu Xiao-Dong Zhu Dousheng Bai Yajin Chen Yongjun Chen Chaoliu Dai Rongping Guo Wenzhi Guo Chunyi Hao Tao Huang Zhiyong Huang Deyu Li Gang Li Tao Li Xiangcheng Li Guangming Li Xiao Liang Jingfeng Liu Fubao Liu Shichun Lu Zheng Lu Weifu Lv Yilei Mao Guoliang Shao Yinghong Shi Tianqiang Song Guang Tan Yunqiang Tang Kaishan Tao Chidan Wan Guangyi Wang Lu Wang Shunxiang Wang Tianfu Wen Baocai Xing Bangde Xiang Sheng Yan Dinghua Yang Guowen Yin Tao Yin Zhenyu Yin Zhengping Yu Bixiang Zhang Jialin Zhang Shuijun Zhang Ti Zhang Yamin Zhang Yubao Zhang Aibin Zhang Haitao Zhao Ledu Zhou Wu Zhang Zhenyu Zhu Shukui Qin Feng Shen Xiujun Cai Gaojun Teng Jianqiang Cai Minshan Chen Qiang Li Lianxin Liu Weilin Wang Tingbo Liang Jiahong Dong Xiaoping Chen Xuehao Wang Shusen Zheng Jia Fan 无 | 2022 | Hepatobiliary Surgery and Nutrition2022，11，2： | 4 |
| 19 | Tick-borne Pathogens in Shanxi Province, China显示文摘Ticks are recognized as one of the most important vectors that cause diseases in animals and humans,and have significant public health impacts worldwide[1].They have a wide range of hosts among terrestrial vertebrates,including mammals,birds,amphibians.The numerous zoonotic pathogens transmitted by ticks are the causative agents of Lyme disease,rickettsiosis,ehrlichioses,relapsing fever,Q fever,and tularemia.Cases of tick-borne diseases are increasing around the world and some emerging or re-emerging pathogens are being discovered,which pose great challenges for prevention and control. | YANG Xiao Na YANG Hui Jun ZHANG Lin HOU Xue Xia MIAO Guang Qing CAO Hong Bing HAO Rui E HAO Qin | 2021 | Biomedical and Environmental Sciences2021，34，5： | 4 |
| 20 | Total Energy Expenditure of 16 Chinese Young Men Measured by the Doubly Labeled Water Method显示文摘Objective Doubly labeled water (DLW) method is the gold standard for measuring total energy expenditure (TEE). We used this method to measure TEE in Chinese young men. Methods Sixteen healthy young men age 23±1 years with body mass index 22.0±1.4 kg/m 2 were recruited. TEE was measured by the DLW method, and basal energy expenditure (BEE) was determined by indirect calorimetry. We also conducted 24-h activity, energy balance and factorial approach to estimate energy requirements of the subjects. Results TEE of subjects by DLW method was 9.45±0.57 MJ/day (2258±180 kcal/day). The 24-h activity was 10.80±0.33 MJ/day (2582±136 kcal/day). The energy requirement, derived from energy balance observations, was 9.93±1.32 MJ/day (2373±315 kcal/day). The BEE of 6.65±0.28 MJ/day (1589±67 kcal/day), calculated by the adjusted Schofield equation, was significantly higher (P<0.001) than that measured by indirect calorimetry, 5.99±0.66 MJ/day (1433±158 kcal/day). The TEE derived from the factorial approach was 10.31±0.43 MJ/day (2463±104 kcal/day). Conclusion The TEE of Chinese young men measured by the DLW method was about 10% lower than the current recommended nutrient intake (RNI), suggesting that the RNI for Chinese men maybe overestimated. Further studies are warranted to determine the value of the estimated energy requirement. | ZHUO Qin SUN Rui GOU Ling Yan PIAO Jian Hua LIU Jian Min TIAN Yuan ZHANG Yu Hui YANG Xiao Guang | 2013 | Biomedical and Environmental Sciences2013，26，6： | 4 |
