1Association between p21 Ser31Arg polymorphism and cancer risk:a meta-analysis显示文摘P21(CDKN1A),a key cell cycle regulatory protein that governs cell cycle progression from G1 to S phase,can regulate cell proliferation,growth arrest,and apoptosis.The Ser31Arg polymorphism is located in the highly conserved region of p21 and may encode functionally distinct proteins.Although many epidemiological studies have been conducted to evaluate the association between the p21 Ser31Arg polymorphism and cancer risk,the findings remain conflicting.This meta-analysis with 33 077 cases and 45 013 controls from 44 published case-control studies showed that the variant homozygous 31Arg/Arg genotype was associated with an increased risk of numerous types of cancers in a random-effect model(homozygote comparison:OR = 1.17,95% CI = 0.99 to 1.37,P = 0.0002 for the heterogeneity test;recessive model comparison:OR = 1.16,95% CI = 1.01 to 1.33,P = 0.0001 for the heterogeneity test).Stratified analysis revealed that increased cancer risk associated with the 31Arg/Arg genotype remained significant in subgroups of colorectal cancer,estrogen-related cancer,Caucasians,population-based studies,studies with matching information or a larger sample size.Heterogeneity analysis showed that tumor type contributed to substantial between-study heterogeneity(recessive model comparison:χ2 = 21.83,df = 7,P = 0.003).The results from this large-sample sized meta-analysis suggest that the p21 31Arg/Arg genotype may serve as a potential marker for increased cancer risk.Hongxia Ma Ziyuan Zhou Sheng Wei Qingyi Wei 2011Chinese Journal of Cancer2011,30,4:3
2Energy-limiting factor for coal and gas outburst occurrence in intact coal seam显示文摘This research reviewed the mechanics and gas desorption properties of intact coal,and tested the crushing work ratios of different intact coals,and then,studied the stress conditions for the failure or crushing of intact coal and the gas demand for the pulverization of intact coal particles.When a real-life outburst case is examined,the required minimum stress for intact coal outburst is estimated.The study concludes that the crushing work ratios of three intact coal samples vary from 294.3732 to 945.8048 J/m^(2).For the real-life case,more than 2300 MJ of transport work is needed,and 10062.09,7046.57 and 5895.47 m^(3) of gas is required when the gas pressure is 1,2 and 3 MPa,respectively.The crushing work exceeds the transport work and even reaches 13.96 times of the transport work.How to provide such an enormous crushing work is an energy-limiting factor for the outburst in intact coal.The strain energy is needed for the crushing work,and the required minimum stress is over 54.35 MPa,even reaching 300.44 MPa.These minimum stresses far exceed the in-situ vertical and horizontal stresses that can be provided at the 300–700 m mining depth range.Qingyi Tu Yuanping Cheng Sheng Xue Ting Ren Xiang Cheng 2021International Journal of Mining Science and Technology2021,31,4:2
3Carboniferous integrative stratigraphy and timescale of China显示文摘The Carboniferous period lasted about 60 Myr, from ~358.9 Ma to ~298.9 Ma. According to the International Commission on Stratigraphy, the Carboniferous System is subdivided into two subsystems, i.e., Mississippian and Pennsylvanian, including 6 series and 7 stages. The Global Stratotype Sections and Points(GSSPs) of three stages have been ratified, the Tournaisian, Visean, and Bashkirian stages. The GSSPs of the remaining four stages(i.e., the Serpukhovian, Moscovian,Kasimovian, and Gzhelian) have not been ratified so far. This paper outlines Carboniferous stratigraphic subdivision and correlation on the basis of detailed biostratigraphy mainly from South China, and summarizes the Carboniferous chronostratigraphic framework of China. High-resolution biostratigraphic study reveals 37 conodont zones, 24 foraminiferal(including fusulinid) zones, 13 ammonoid zones, 10 brachiopod zones, and 10 rugose coral zones in the Carboniferous of China. The biostratigraphic framework based on these biozones warrants the precise correlation of regional stratigraphy of China(including2 subsystems, 4 series, and 8 stages) to that of the other regions globally. Meanwhile, the Carboniferous chemo-, sequence-,cyclo-, and event-stratigraphy of China have been intensively studied and can also be correlated worldwide. Future studies on the Carboniferous in China should focus on(1) the correlation between shallow-and deep-water facies and between marine and continental facies,(2) high-resolution astronomical cyclostratigraphy, and(3) paleoenvironment and paleoclimate analysis based on geochemical proxies such as strontium and oxygen isotopes, as well as stomatal indices of fossil plants.Xiangdong WANG Keyi HU Wenkun QIE Qingyi SHENG Bo CHEN Wei LIN Le YAO Qiulai WANG Yuping QI Jitao CHEN Zhuoting LIAO Junjun SONG 2019Science China Earth Sciences2019,62,1:2
4High-throughput RNA sequencing reveals the anti-inflammatory mechanism of baicalin on Propionibacterium acnes-induced acne in rabbits显示文摘Objective:Propionibacterium acnes(P.acnes)plays an important role in the development of acne,an inflammatory skin disease with a high-incidence.In this study,we used high-throughput RNA sequencing(RNA-seq)to reveal the anti-inflammatory mechanism of baicalin on P.acnes-induced acne in rabbits.Methods:The Kligman method was used to induce acne in the ears of New Zealand rabbits.The effect of baicalin on the acne model was evaluated by the number of acne lesions and hematoxylin and eosin(H&E)staining of acne tissues.Enzyme-linked immunoabsorbent assay was used to measure the protein expression levels of tumor necrosis factor a(TNFA),interleukin-1 b(IL1B),IL6,and IL8 in the serum of rabbits.RNA-seq was performed to investigate the mechanism of anti-inflammatory activities of baicalin on acne.Immunohistochemical analysis and Western blot were used to validate the expression levels of related proteins in acne tissues.Results:Baicalin treatment significantly reduced the number of acne lesions and lesions of the ear as well as levels of serum inflammatory cytokines.RNA-seq data showed that baicalin treatment globally suppressed inflammation,especially the TNF signaling pathway and Staphylococcus aureus infection pathway,in the rabbit acne model.Conclusion: Baicalin effectively ameliorates P. acnes-induced acne in rabbits by suppressingthe inflammatory response in rabbits.Xingzhe Yang Guangrui Huang Leiming You Honghao Sheng Yuxiu Sun Yuyin Feng Qingyi Lu Anlong Xu 2019Journal of Traditional Chinese Medical Sciences2019,6,3:2
5Highly oriented MAPbI3 crystals for efficient hole-conductor-free printable mesoscopic perovskite solar cells显示文摘Highly crystalline perovskite films with large grains and few grain boundaries are conducive for efficient and stable perovskite solar cells.Current methods for preparing perovskite films are mostly based on a fast crystallization process,with rapid nucleation and insufficient growth.In this study,MAPbI3 perovskite with inhibited nucleation and promoted growth in the TiO_(2)/ZrO_(2)/carbon triple mesoscopic scaffold was crystallized by modulating the precursor and the crystallization process.N-methylformamide showed high solubility for both methylammonium iodide and Pbl2 and hampered the formation of large colloids in the MAPbI3 precursor solution.Furthermore,methylammonium chloride was added to reduce large colloids,which are a possible source of nucleation sites.During the crystallization of MAPbI3,the solvent was removed at a slow controlled speed,to avoid rapid nucleation and provide sufficient time for crystal growth.As a result,highly oriented MAPbI3 crystals with suppressed non-radiative recombination and promoted charge transport were obtained in the triple mesoscopic layer with disordered pores.The corresponding hole-conductor-free,printable mesoscopic perovskite solar cells exhibited a highest power conversion efficiency of 18.82%.The device also exhibited promising long-term operational sta-bility of 1000 h under continuous illumination at maximum power point at 55±5°C and damp-heat stability of 1340 h aging at 85°C as well as 85%relative humidity.Shuang Liu Deyi Zhang Yusong Sheng Weihua Zhang Zhaotong Qin Minchao Qin Sheng Li Yifan Wang Chenxu Gao Qifei Wang Yue Ming Chao Liu Kai Yang Qingyi Huang Jianhang Qi Qiaojiao Gao Kai Chen Yue Hu Yaoguang Rong Xinhui Lu Anyi Mei Hongwei Han 2022Fundamental Research2022,2,2:1
6Highly-active,metal-free,carbon-based ORR cathode for efficient organics removal and electricity generation in a PFC system显示文摘A highly-active,metal-free,carbon-based oxygen reduction reaction(ORR)cathode,i.e.,graphitized Ndoped carbon felt(GNCF),was prepared,for the first time,by in-situ modifying the doping species of polyacrylonitrile(PAN)-based carbon felt(CF)via a facile annealing process in Ar atmosphere.It was applied for dramatically enhanced organics degradation and electricity generation in a photocatalytic fuel cell(PFC)system.The GNCF showed enhanced specific surface area,improved graphitization and raised ratio of graphitic N,therefore resulting in excellently improved ORR performance compared to the CF.When applying the GNCF as a cathode in a PFC system,the proposed PFC showed significant improvement in degrading various model organic contaminants and outputing electricity simultaneously when compared with the PFC with CF.For instance,the apparent rate constant and electricity output efficiency showed~10.6 times and~7.2 times,respectively,improvement when using rhodamine B as model waste.Further improved performance was also achieved by aeration of air or O^(2) due to the fu rther enhanced ORR.The proposed PFC was also efficient in a wide pH,and kept outsta nding stability in long-term utilization.Qingyi Zeng Sheng Chang Mingqi Wang Mi Li Qin wen Deng Zhu Xiong Baoxue Zhou Yanbiao Liu 2021Chinese Chemical Letters2021,32,7:0
7Expert consensus on prevention and cardiopulmonary resuscitation for cardiac arrest in COVID-19显示文摘Background:Cardiopulmonary resuscitation(CPR)strategies in COVID-19 patients differ from those in patients suffering from cardiogenic cardiac arrest.During CPR,both healthcare and non-healthcare workers who provide resuscitation are at risk of infection.The Working Group for Expert Consensus on Prevention and Cardiopulmonary Resuscitation for Cardiac Arrest in COVID-19 has developed this Chinese Expert Consensus to guide clinical practice of CPR in COVID-19 patients.Main recommendations:1)A medical team should be assigned to evaluate severe and critical COVID-19 for early monitoring of cardiac-arrest warning signs.2)Psychological counseling and treatment are highly recommended,since sympathetic and vagal abnormalities induced by psychological stress from the COVID-19 pandemic can induce cardiac arrest.3)Healthcare workers should wear personal protective equipment(PPE).4)Mouth-to-mouth ventilation should be avoided on patients suspected of having or diagnosed with COVID-19.5)Hands-only chest compression and mechanical chest compression are recommended.6)Tracheal-intubation procedures should be optimized and tracheal-intubation strategies should be implemented early.7)CPR should be provided for 20-30 min.8)Various factors should be taken into consideration such as the interests of patients and family members,ethics,transmission risks,and laws and regulations governing infectious disease control.Changes in management:The following changes or modifications to CPR strategy in COVID-19 patients are proposed:1)Healthcare workers should wear PPE.2)Hands-only chest compression and mechanical chest compression can be implemented to reduce or avoid the spread of viruses by aerosols.3)Both the benefits to patients and the risk of infection should be considered.4)Hhealthcare workers should be fully aware of and trained in CPR strategies and procedures specifically for patients with COVID-19.Wei Song Jie Wei Xiangdong Jian Deren Wang Yanhong Ouyang Yuanshui Liu Xianjin Du Ying Chen Yingqi Zhang Heping Xu Shuming Xianyu Qiong Ning Xiang Li Xiaotong Han Feng Zhan Tao Yu Wenteng Chen Jun Zhang Wenwei Cai Sheng’ang Zhou Shengyang Yi Yu Cao Xiaobei Chen Shunjiang Xu Zong’an Liang Duohu Wu Fen Ai Zhong Wang Qingyi Meng Yuhong Mi Sisen Zhang Rongjia Yang Shouchun Yan Wenbin Han Yong Lin Chuanyun Qian Wenwu Zhang Yan Xiong Jun Lv Baochi Liu Yan Cao Xiaojun He Xuelian Sun Yufang Cao Tian’en Zhou 2021Asian Pacific Journal of Tropical Medicine2021,14,6:0
