1Further support for a Cretaceous age for the feathered-dinosaur beds of Liaoning,China:New ^(40)Ar/^(39)Ar dating of the Yixian and Tuchengzi Formations显示文摘We report new 40Ar/39Ar dating results ob-tained from total fusion and incremental-heating analyses of sanidine and biotite from three tuffs found interbedded within the fossil-bearing deposits of Liaoning, northeast China. The first is a new sample of the Bed 6 Sihetun tuff from the Yixian Formation, previously dated by our team as middle Early Cretaceous, and recently considered by Lo et al., partially reset due to metamorphism from a nearby ba-saltic sill. The second is the Yixian Bed 9 tuff from Heng-daozi considered by Lo et al. to be unaffected by metamor-phism and whose age, based on total fusion 40Ar/39Ar dating of biotite, argues for a Jurassic age for the Yixian Formation. The third tuff is a previously undated tuff from the upper part of the underlying Tuchengzi Formation. Single crystal total fusion 40Ar/39Ar analyses of the Sihetun sanidine showed homogeneous radiogenic Ar, Ca/K ratios, excellent reproducibility and gave a mean age of 125.0 ± 0.18 (1SD) ± 0.04 (SE) Ma.

2A nearly completely articulated rhamphorhynchoid pterosaur with exceptionally well-preserved wing membranes and 'hairs' from Inner Mongolia, northeast China显示文摘We report a new and nearly completely articu-lated rhamphorhynchoid pterosaur, Jeholopterus ningchen-gensis gen. et sp. nov., with excellently preserved fibres in the wing membrane and 'hairs' in the neck, body and tail re-gions. Many of its characteristics such as a short neck, short metacarpals and distinctively long fifth pedal digit are char-acteristic of rhamphorhynchoids. The new species can be further referred to the ’strange’ short-tailed rhamphorhyn-choid family Anurognathidae. It is much more complete than the other known members of the family, namely, Anurog-nathus from Solnhofen, Germany, Batrachognathus from Karatau, Kazakhstan, and Dendrorhynchoides from Beipiao, Liaoning Province, China. The new pterosaur also shows that the wing membrane is attached to the ankle of the hind limb. The pedal digits are webbed. Furthermore, the 'hair' of Jeholopterus bears some resemblance to the hair-like in-tegumental structures of the feathered dinosaur Sinosaurop-teryx although there is yet no directXiaolin Wang Zhonghe Zhou Fucheng Zhang Xing Xu 2002Chinese Science Bulletin2002,47,3:37
3Whole-genome sequencing of 508 patients identifies key molecular features associated with poor prognosis in esophageal squamous cell carcinoma显示文摘Esophageal squamous cell carcinoma(ESCC)is a poor-prognosis cancer type with limited understanding of its molecular etiology.Using 508 ESCC genomes,we identified five novel significantly mutated genes and uncovered mutational signature clusters associated with metastasis and patients’outcomes.Several functional assays implicated that NFE2L2 may act as a tumor suppressor in ESCC and that mutations in NFE2L2 probably impaired its tumor-suppressive function,or even conferred oncogenic activities.Additionally,we found that the NFE2L2 mutations were significantly associated with worse prognosis of ESCC.We also identified potential noncoding driver mutations including hotspot mutations in the promoter region of SLC35E2 that were correlated with worse survival.Approximately 5.9%and 15.2%of patients had high tumor mutation burden or actionable mutations,respectively,and may benefit from immunotherapy or targeted therapies.We found clinically relevant coding and noncoding genomic alterations and revealed three major subtypes that robustly predicted patients’outcomes.Collectively,we report the largest dataset of genomic profiling of ESCC useful for developing ESCC-specific biomarkers for diagnosis and treatment.Yongping Cui Hongyan Chen Ruibin Xi Heyang Cui Yahui Zhao Enwei Xu Ting Yan Xiaomei Lu Furong Huang Pengzhou Kong Yang Li Xiaolin Zhu Jiawei Wang Wenjie Zhu Jie Wang Yanchun Ma Yong Zhou Shiping Guo Ling Zhang Yiqian Liu Bin Wang Yanfeng Xi Ruifang Sun Xiao Yu Yuanfang Zhai Fang Wang Jian Yang Bin Yang Caixia Cheng Jing Liu Bin Song Hongyi Li Yi Wang Yingchun Zhang Xiaolong Cheng Qimin Zhan Yanhong Li Zhihua Liu-Show 2020Cell Research2020,30,10:19
4Distribution and elimination of polycyclic musks in three sewage treatment plants of Beijing, China显示文摘The two representative polycyclic musks, 1-(5,6,7,8-tetrahydro-3,5,5,6,8,8-hexamethyl-2-naphthenyl)-ethanone (AHTN) and 1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta[g]-2-benzopyrane (HHCB), were measured in aqueous samples and sludge samples of three sewage treatment plants (STPs) in Beijing, China using a gas chromatograph-mass spectrometry. The HHCB and AHTN concentration ranges in the influents were 1251.4-3003.8 ng/L and 111.9-286.3 ng/L, respectively. Meanwhile, the ranges of 492.8-1285.3 ng/L for HHCB and 47.3-89.3 ng/L for AHTN were present in the effluents. The musks in the sludges were three to four orders of magnitude higher than those in aqueous sewages. The removal efficiencies of the two musks varied in the ranges of 41.7%- 70.1% for HHCB, and 25.5%-68.8% for AHTN. Adsorption onto suspended particulate matter played an important role in removing musks from the sewages. The HHCB/AHTN ratio along the treatment processes showed that the two musks had high similarity of removal from sewage by each reactor in STP. The musks in the effluent sewages may pose a low potential risk to aquatic environment in terms of the predicted-non-effect concentration. Nevertheless, considering the possible additive and synergistic effects with other compounds emitted via STPs, their bioconcentration and bioaccumulation in aquatic organisms and so on, it is essential to monitor these compounds in various compartments and to study their environmental fate.ZHOU Haidong HUANG Xia GAO Mijun WANG Xiaolin WEN Xianghua 2009Journal of Environmental Sciences2009,21,5:17

61.3 kW monolithic linearly polarized single-mode master oscillator power amplifier and strategies for mitigating mode instabilities显示文摘We report on the high-power amplification of a 1064 nm linearly polarized laser in an all-fiber polarizationmaintained master oscillator power amplifier,which can operate at an output power level of 1.3 kW.The beam quality(M^2) was measured to be <1.2 at full power operation.The polarization extinction rate of the fiber amplifier was measured to be above 94% before mode instabilities(MIs) set in,which reduced to about 90% after the onset of MI.The power scaling capability of strategies for suppressing MI is analyzed based on a semianalytical model,the theoretical results of which agree with the experimental results.It shows that mitigating MI by coiling the gain fiber is an effective and practical method in standard double-cladding large mode area fiber,and,by tight coiling of the gain fiber to the radius of 5.5 cm,the MI threshold can be increased to three times higher than that without coiling or loose coiling.Experimental studies have been carried out to verify the idea,which has proved that MI was suppressed successfully in the amplifier by proper coiling.Rumao Tao Pengfei Ma Xiaolin Wang Pu Zhou Zejin Liu 2015Photonics Research2015,3,3:15

9Factors predicting sensory and motor recovery after the repair of upper limb peripheral nerve injuries显示文摘OBJECTIVE: To investigate the factors associated with sensory and motor recovery after the repair of upper limb peripheral nerve injuries. DATA SOURCES: The online PubMed database was searched for English articles describing outcomes after the repair of median, ulnar, radial, and digital nerve injuries in humans with a publication date between 1 January 1990 and 16 February 2011. STUDY SELECTION: The following types of article were selected:(1) clinical trials describing the repair of median, ulnar, radial, and digital nerve injuries published in English; and(2) studies that reported sufficient patient information, including age, mechanism of injury, nerve injured, injury location, defect length, repair time, repair method, and repair materials. SPSS 13.0 software was used to perform univariate and multivariate logistic regression analyses and to investigate the patient and intervention factors associated with outcomes. MAIN OUTCOME MEASURES: Sensory function was assessed using the Mackinnon-Dellon scale and motor function was assessed using the manual muscle test. Satisfactory motor recovery was defined as grade M4 or M5, and satisfactory sensory recovery was defined as grade S3+ or S4.RESULTS: Seventy-one articles were included in this study. Univariate and multivariate logistic regression analyses showed that repair time, repair materials, and nerve injured were independent predictors of outcome after the repair of nerve injuries(P < 0.05), and that the nerve injured was the main factor affecting the rate of good to excellent recovery. CONCLUSION: Predictors of outcome after the repair of peripheral nerve injuries include age, gender, repair time, repair materials, nerve injured, defect length, and duration of follow-up.Bo He Zhaowei Zhu Qingtang Zhu Xiang Zhou Canbin Zheng Pengliang Li Shuang Zhu Xiaolin Liu Jiakai Zhu 2014Neural Regeneration Research2014,9,6:12
10First mass measurement of short-lived nuclides at HIRFL-CSR显示文摘Recent commissioning of the HIRFL-CSR has demonstrated its ability to perform direct mass measurement for short-lived nuclides. Projectile fragments produced by the 78Kr ions at 481.88 MeV/u were separated with the new radioactive beam line in Lanzhou (RIBLL2), and injected into and stored in the experimental storage ring (CSRe). By operating the CSRe as an isochronous mass spectrometry, a typical mass resolution around 2.0×10?5 has been achieved. The masses for 63Ge, 65As and 67Se were measured for the first time. The measured masses are compared with theoretical predictions and the location of the proton drip-line for As isotopes is discussed. The implication of the 65As mass in the astrophysical rapid proton capture process has also been addressed.XU HuShan TU XiaoLin YUAN YouJin XIA JiaWen ZANG YongDong WANG Meng MAO RuiShi HU ZhengGuo MEI Bo SHUAI Peng ZHU ZhiChao TANG ShuWen GENG Peng LIU Yong ZHAO TieCheng ZHANG XueYing YANG JianCheng MAO LiJun ZHANG YuHu ZHOU XiaoHong HUANG WenXue XIAO GuoQing ZHAO HongWei ZHAN WenLong 2009Chinese Science Bulletin2009,54,24:11
11Retrospective study of Traditional Chinese Medicine treatment of type 2 diabetes mellitus显示文摘OBJECTIVE: To provide clinical evidence in support of Dahuang Huanglian Xiexin decoction(DHXD) to treat type 2 diabetes mellitus(T2DM) and to introduce a new treatment option for clinicians.METHODS: Retrospective analysis was used to evaluate DHXD for the treatment of T2DM by analyzing clinical records of 183 cases. Patients with T2DM who met the inclusion criteria between January 1,2013 and January 1, 2014 were enrolled. The effects of the treatment were evaluated by the changes in fasting blood-glucose(FBG), postprandial blood sugar(PBG), hemoglobin A1c(Hb Alc), blood lipid profiles and body mass index(BMI) at 1, 2, 3 and 6 months. The changes in main symptoms were alsoevaluated. The dosage of Huanglian(Rhizoma Coptidis) and related factors were analyzed.RESULTS: There was a significant improvement in mean Hb A1C at 3 and 6 months after DHXD treatment compared with the baseline level(P < 0.01).There were also significant improvements in FBG,PBG, blood lipid series and BMI. DHXD also improved the main symptoms of stomach and intestine excessive heat syndrome in patients with obese T2DM. Huanglian(Rhizoma Coptidis) was the most frequently used in 678 clinical visits, the dosage of Huanglian(Rhizoma Coptidis) was related to age, BMI, DM duration, the level of blood glucose,and use of Western hypoglycemic drugs.CONCLUSION: This study suggests that DHXD could decrease blood glucose and improve T2DM symptoms and reduce body weight. The use of DHXD may indicate a new optional treatment for T2 DM.Pang Bing Guo Jing Zhao Linhua Zhao Xiyan Zhou Qiang Tong Xiaolin 2016Journal of Traditional Chinese Medicine2016,36,3:11

13Machining Characteristics in Cryogenic Grinding of SiCp/Al Composites显示文摘In this study, liquid nitrogen was applied to grind Si Cp/Al composites with high volume fraction and large Si C particle at different levels of cutting conditions, and the effects of grinding depth and speed on grinding force, surface morphology, and surface roughness were investigated. At the same time, the effect of cryogenic cooling was also compared with that of conventional wet grinding. The experimental results indicated that cryogenic cooling is effective in enhancing supporting function of Al matrix to the Si C particles and improving surface quality. Additionally, the brittle fracture of Si C particles was suppressed and some ductile streaks on Si C particle could be observed.Li Zhou Shutao Huang Xiaolin Yu 2014Acta Metallurgica Sinica(English Letters)2014,27,5:9
14All-fiberized and narrow-linewidth 5 kW power-level fiber amplifier based on a bidirectional pumping configuration显示文摘In this paper,an all-fiberized and narrow-linewidth 5 kW power-level fiber amplifier is presented.The laser is achieved based on the master oscillator power amplification configuration,in which the phase-modulated single-frequency laser is applied as the seed laser and a bidirectional pumping configuration is applied in the power amplifier.The stimulated Brillouin scattering,stimulated Raman scattering,and transverse mode instability effects are all effectively suppressed in the experiment.Consequently,the output power is scaled up to 4.92 kW with a slope efficiency of as high as approximately 80%.The 3-dB spectral width is about 0.59 nm,and the beam quality is measured to be M^(2)~1.22 at maximum output power.Furthermore,we have also conducted a detailed spectral analysis on the spectral width of the signal laser,which reveals that the spectral wing broadening phenomenon could lead to the obvious decrease of the spectral purity at certain output power.Overall,this work could provide a reference for obtaining and optimizing high-power narrow-linewidth fiber lasers.Pengfei Ma Hu Xiao Wei Liu Hanwei Zhang Xiaolin Wang Jinyong Leng Pu Zhou 2021High Power Laser Science and Engineering2021,9,3:9
15Efficacy 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
16Efficacy and safety of low-dose interleukin-2 in combination with methotrexate in patients with active rheumatoid arthritis:a randomized,double-blind,placebo-controlled phase 2 trial显示文摘Rheumatoid arthritis(RA)is an aggressive autoimmune arthritis,and current therapies remain unsatisfactory due to low remission rate and substantially adverse effects.Low-dose interleukin-2(Ld-IL2)is potentially a therapeutic approach to further improve the disease.This randomized,double-blind,placebo-controlled trial was undertaken to evaluate the efficacy and safety of Ld-IL2 in patients with active RA.Patients were randomly assigned(1:1)to receive Ld-IL2,defined as a dose of 1 million IU,or placebo in a 12-week trial with a 12-week follow-up.Three cycles of Ld-IL2 or placebo were administered subcutaneously every other day for 2 weeks(a total of 7 doses),followed by a 2-week break.All patients received a stable dose of methotrexate(MTX).The primary outcomes were the proportion of patients achieving the ACR20,DAS28-ESR<2.6,and the change from baseline in CDAI or SDAI at week 24.Secondary endpoints included other clinical responses and safety.The primary outcomes were achieved in the perprotocol population.The improvements from baseline in CDAI and SDAI were significantly greater across time points for the LdIL2+MTX group(n=17)than for the placebo+MTX group(n=23)(P=0.018 and P=0.015,respectively).More patients achieved ACR20 response in the Ld-IL2+MTX group than those in the placebo+MTX group at week 12(70.6%vs 43.5%)and at week 24(76.5%vs 56.5%)(P=0.014).In addition,low Treg and high IL-21 were associated with good responses to Ld-IL2.Ld-IL-2 treatment was well-tolerated in this study.These results suggested that Ld-IL2 was effective and safe in RA.ClinicalTrials.gov number:NCT 02467504.Xiaoying Zhang Miao Miao Ruijun Zhang Xu Liu Xiaozhen Zhao Miao Shao Tian Liu Yuebo Jin Jiali Chen Huixin Liu Xia Zhang Yun Li Yunshan Zhou Yue Yang Ru Li Haihong Yao Yanying Liu Chun Li Yuhui Li Limin Ren Yin Su Xiaolin Sun Jing He Zhanguo Li 2022Signal Transduction and Targeted Therapy2022,7,4:7
17Synthesis and Luminescence of SrZnO_2∶Eu^(3+), Li^+ Phosphor by Long Wavelength UV Excitation显示文摘SrZnO2∶Eu 3+, Li+ phosphor powder by long wavelength UV excitation was synthesized by conventional solid-state reaction method. XRD and PL were employed to characterize their properties. The results show that Eu 3+ ions preferentially occupy Sr 2+ asymmetry cationic sites, thus emitting 612 nm red light originated from 5D0 to 7F2 transition. The luminescent intensity can be greatly enhanced with incorporation of Li+ ions. The excitation efficiency in range of 350~400 nm also increases greatly due to incorporating Li+ ions. SrZnO2∶Eu 3+, Li+ is a promising red-emitting phosphor by long wavelength UV excitation.Yu Xibin Yang Liangzhun Yang Shiping Zhou Chunlei Xu Xiaolin Tang Jingfen Peng Xiudong 2005Journal of Rare Earths2005,23,5:7
181-MCP Regulates Ethanol Fermentation and GABA Shunt Pathway Involved in Kiwifruit Quality During Postharvest Storage显示文摘Kiwifruit(Actinidia deliciosa)‘Bruno’is prone to accumulate ethanol rapidly after respiratory climacteric during storage at ambient conditions without stresses,which causes quality deterioration of the fruit associated with alcohol off-flavor.For maintaining the postharvest quality of kiwifruit‘Bruno’,the effects of 1.0μL•L^−11-methylcyclopropene(1-MCP)treatment on regulating the ethanol fermentation andγ-aminobutyric acid(GABA)shunt pathway associated with control of alcohol off-flavor were investigated during storage at room temperature(24±1)°C for 27 days.The results showed that 1-MCP treatment significantly reduced the respiration rate,ethylene production,decay rate,ascorbic acid(AsA)loss,and delayed the decline in the firmness and titratable acidity(TA),and the increase in total soluble solid(TSS)in kiwifruit.Furthermore,1-MCP treatment effectively inhibited the increases in contents of acetaldehyde,ethanol,and GABA along with the suppressed activities of key enzymes involved in ethanol fermentation and GABA shunt pathway,such as pyruvate decarboxylase(PDC),alcohol dehydrogenase(ADH),glutamate decarboxylase(GAD),and GABA-transaminase(GABA-T)in kiwifruit during storage.In conclusion,1-MCP treatment efficiently regulated the ethanol fermentation and GABA shunt pathway by delaying the ripening process to avoid the alcohol off-flavor development,thereby contributed to maintaining the quality of the kiwifruit.Maratab Ali Muhammad Ammar Raza Shenge Li Lichao Zhou Chen Huan Shen Shuling Xiaolin Zheng 2021Horticultural Plant Journal2021,7,1:7
19Marginal sealing around integral bilayer scaffolds for repairing osteochondral defects based on photocurable silk hydrogels显示文摘Osteochondral repair remains a major challenge in current clinical practice despite significant advances in tissue engineering.In particular,the lateral integration of neocartilage into surrounding native cartilage is a difficult and inadequately addressed problem that determines the success of tissue repair.Here,a novel design of an integral bilayer scaffold combined with a photocurable silk sealant for osteochondral repair is reported.First,we fabricated a bilayer silk scaffold with a cartilage layer resembling native cartilage in surface morphology and mechanical strength and a BMP-2-loaded porous subchondral bone layer that facilitated the osteogenic differentiation of BMSCs.Second,a TGF-β3-loaded methacrylated silk fibroin sealant(Sil-MA)exhibiting biocompatibility and good adhesive properties was developed and confirmed to promote chondrocyte migration and differentiation.Importantly,this TGF-β3-loaded Sil-MA hydrogel provided a bridge between the cartilage layer of the scaffold and the surrounding cartilage and then guided new cartilage to grow towards and replace the degraded cartilage layer from the surrounding native cartilage in the early stage of knee repair.Thus,osteochondral regeneration and superior lateral integration were achieved in vivo by using this composite.These results demonstrate that the new approach of marginal sealing around the cartilage layer of bilayer scaffolds with Sil-MA hydrogel has tremendous potential for clinical use in osteochondral regeneration.Xiaolin Wu Mingliang Zhou Fei Jiang Shi Yin Sihan Lin Guangzheng Yang Yuezhi Lu Wenjie Zhang Xinquan Jiang 2021Bioactive Materials2021,6,11:7
