5Effect of Jinhua Qinggan granules on novel coronavirus pneumonia in patients显示文摘OBJECTIVE: To evaluate the effectiveness and safety of Jinhua Qinggan granules in the treatment of patients with novel coronavirus pneumonia(COVID-19).METHODS: Eighty cases of COVID-19 diagnosed from January 24 to February 17, 2020 in Beijing YouAn Hospital Affiliated to Capital Medical University were retrospectively analyzed. All 80 patients received symptomatic and supportive treatment.Among them, 44 patients took Jinhua Qinggan granules(treatment group) within 24 h of admission, and the remaining 36 patients either did not take Jinhua Qinggan granules or took the granules for less than 2 d(control group). In this study, we compared the duration of viral nucleic acid detection and of pneumonia absorption improvement between the two groups.RESULTS: Among the 80 cases, 37 were male(46%)and 43 were female(54%) with age ranging from15 to 86 years, with an average age of 51.19 years.The average duration of viral nucleic acid detection was(7 ± 4) d in the Jinhua Qinggan administration group and(10 ± 4) d for the control group(P =0.010), following which, nucleic acid tests were negative. Of the two groups, 56.82% in the Jinhua Qinggan treatment group and 27.78% in the control group demonstrated negative nucleic acid tests within 7 d or less. The 7-day viral clearance rate was significantly higher in the Jinhua Qinggan group compared with the control group(P = 0.009). Furthermore, the pneumonia recovery time indicated by chest CT was(8 ± 4) d in the Jinhua Qinggan group, which was significantly shorter than the control group, at(10 ± 5) d(P = 0.021). No adverse reactions were found in the treatment group after taking this medicine.CONCLUSION: In patients with COVID-19, Jinhua Qinggan granules can effectively shorten the duration of nucleic acid detection and promote the absorption of pneumonia inflammatory exudate without obvious adverse reactions.Liu Zengli Li Xiuhui Gou Chunyan Li Li Luo Xiaolan Zhang Chun Zhang Yin Zhang Jiaying Jin Aihua Li Hongyan Zeng Yuan Li Tongzeng Wang Xiaojun 2020Journal of Traditional Chinese Medicine2020,40,3:11
6Solution structure of the RNA recognition domain of METTL3-METTL14 N^6-methyladenosine methyltransferase显示文摘N^6-methyladenosine(m6A),a ubiquitous RNA modification,is installed by METTL3-METTL14 complex.The structure of the heterodimeric complex between the methyltransferase domains(MTDs)of METTL3 and METTL14 has been previously determined.However,the MTDs alone possess no enzymatic activity.Here we present the solution structure for the zinc finger domain(ZFD)of METTL3,the inclusion of which fulfills the methyltransferase activity of METTL3-METTL14.We show that the ZFD specifically binds to an RNA containing 5'-GGACU-3'consensus sequence,but does not to one without.The ZFD thus serves as the target recognition domain,a structural feature previously shown for DNA methyltransferases,and cooperates with the MTDs of METTL3-METTL14 for catalysis.However,the interaction between the ZFD and the specific RNA is extremely weak,with the binding affinity at several hundred micromolar under physiological conditions.The ZFD contains two CCCH-type zinc fingers connected by an anti-parallel P-sheet.Mutational analysis and NMR titrations have mapped the functional interface to a contiguous surface.As a division of labor,the RNA-binding interface comprises basic residues from zinc finger 1 and hydrophobic residues fromβ-sheet and zinc finger 2.Further we show that the linker between the ZFD and MTD of METTL3 is flexible but partially folded,which may permit the cooperation between the two domains during catalysis.Together,the structural characterization of METTL3 ZFD paves the way to elucidate the atomic details of the entire process of RNA m6A modification.Jinbo Huang Xu Dong Zhou Gong Ling-Yun Qin Shuai Yang Yue-Ling Zhu Xiang Wang Delin Zhang Tingting Zou Ping Yin Chun Tang 2019Protein & Cell2019,10,4:11

8Investigation of Induced Distortions in a-Si∶H/a-SiN_x∶H Multilayers by Raman Scattering Technique显示文摘The a Si∶H/SiN x ∶H sample series are investigated by means of Raman scattering technique(RST). The result shows that due to the structural mismatch between a Si∶H and a SiN x ∶H, severe induced distortions are produced in the interface of the heterojunction, and these induced distortions tend towards a certain energy state. The ordering of the interface structure depends on the periodic number of multilayer thin films.CAO Guo rong 1, GUO Shen kang 1, WANG Zhi chao 2, LIU Yin chun 2, SUN Mei xiang 2 (1.Dept. of Phys., Jiangsu University, Zhenjiang 212003, CHN 2.Dept. of Phys., Nanjing University, Nanjing 210093, CHN) 2002Semiconductor Photonics and Technology2002,8,4:8
9Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 2020Biomedical and Environmental Sciences2020,33,12:8
10Efficacy 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
11Comparing the Diagnostic Criteria of MAFLD and NAFLD in the Chinese Population:A Population-based Prospective Cohort Study显示文摘Background and Aims:Metabolic dysfunction-associ-ated fatty liver disease(MAFLD)is a new concept,pro-posed in 2020;however,its applicability in Asia populations has yet to be evaluated.Therefore,we aimed to compare the difference in epidemiological and clinical characteris-tics between MAFLD and non-alcoholic fatty liver disease(NAFLD)among Asian populations.Methods:Based on the Jinchang cohort,30,633 participants were collected.The prevalence and incidence of MAFLD and NAFLD were used to analyze the epidemic characteristics and its overlapping effects.In addition,the corresponding clinical character-istics of the two diagnostic criteria populations were com-pared.Results:The prevalence rates of MAFLD and NAFLD were 21.03%and 18.83%,respectively.After an average 2.28-year follow-up,the incidence densities of MAFLD and NAFLD were 41.58 per 1,000 person-years and 37.69 per 1,000 person-years,respectively.With the increase of baseline age,body mass index(BMI),and waist circumfer-ence(WC)levels,the prevalence and incidence of MAFLD and NAFLD were on the rise(all ptrend<0.05).Among the total patients diagnosed at baseline or follow-up,most pa-tients had both MAFLD and NAFLD,accounting for 78.84%and 82.88%,respectively.Compared with NAFLD,MAFLD patients had greater proportions of males and metabolic diseases(diabetes,dyslipidemia),and had higher BMI,WC,liver enzymes,blood glucose,and lipid levels in the base-line diagnosis patients(p<0.05).Additionally,lean MAFLD patients had higher metabolic disorders than lean NAFLD patients(p<0.05).Conclusions:Compared with NAFLD,the newly proposed definition of MAFLD is more practical and accurate,and it can help identify more fatty liver pa-tients with high-risk diseases.Cheng Yu Minzhen Wang Shan Zheng Miao Xia Hongyan Yang Desheng Zhang Chun Yin Ning Cheng Yana Bai 2022Journal of Clinical and Translational Hepatology2022,10,1:7
12Establishment of a Predictive Diagnostic Model for Acute Mycoplasma Pneumoniae Infection in Elderly Patients with Community-acquired Pneumonia显示文摘We established a diagnostic model to predict acute Mycoplasma pneumoniae(M.pneumonia)infection in elderly Community-acquired pneumonia(CAP)patients.We divided 456 patients into acute and non-acute M.pneumoniae infection groups.Binary logistic regression and receiver operating characteristic(ROC)curves were used to establish a predictive model.The following independent factors were identified:age≥70 years;serum c TNT level≥0.05 ng/m L;lobar consolidation;mediastinal lymphadenopathy;and antibody titer in the acute phase≥1:40.The area under the ROC curve of the model was 0.923 and a score of≥7score predicted acute M.pneumoniae infection in elderly patients with CAP.The predictive model developed in this study has high diagnostic accuracy for the identification of elderly acute M.pneumoniae infection.XiAO Hong Li XIN De Li WANG Yan CUI Li Jian LIU Xiao Ya LIU Song SONG Li Hong LIU Chun Ling YIN Cheng Hong 2017Biomedical and Environmental Sciences2017,30,7:6
13Loss of Gn1a/OsCKX2 confers heavy-panicle rice with excellent lodging resistance显示文摘Significant achievements have been made in breeding programs for the heavy-panicle-type(HPT)rice(Oryza sativa) in Southwest China. The HPT varieties now exhibit excellent lodging resistance,allowing them to overcome the greater pressures caused by heavy panicles. However, the genetic mechanism of this lodging resistance remains elusive. Here, we isolated a major quantitative trait locus, Panicle Neck Diameter 1(PND1), andidentified the causal gene as GRAIN NUMBER 1 A/CYTOKININ OXIDASE 2(Gn1 A/Os CKX2). The null gn1 a allele from rice line R498(gn1 aR498) improved lodging resistance through increasing the culm diameter and promoting crown root development.Loss-of-function of Gn1 a/Os CKX2 led to cytokinin accumulation in the crown root tip and accelerated the development of adventitious roots. Gene pyramiding between the null gn1 aR498 allele with two gain-of-function alleles, STRONG CULM 2(SCM2)and SCM3, further improved lodging resistance.Moreover, Gn1 a/Os CKX2 had minimal influence on overall rice quality. Our research thus highlights the distinct genetic components of lodging resistance of HPT varieties and provides a strategy for tailormade crop improvement of both yield and lodging resistance in rice.Bin Tu Zhang Tao Shiguang Wang Lei Zhou Ling Zheng Chun Zhang Xinzi Li Xiaoyu Zhang Junjie Yin Xiaobo Zhu Hua Yuan Ting Li Weilan Chen Peng Qin Bingtian Ma Yuping Wang Shigui Li 2022Journal of Integrative Plant Biology2022,64,1:5

15Preparation of nanosized hollow silica spheres from Na_2SiO_3 using Fe_3O_4 nanoparticles as templates显示文摘Nanosized hollow silica spheres with average diameters from 43 to 70 nm were prepared by removal of Fe3O4 templates with hydrochloric acid from silica-coated Fe3O4 core-shell composites. The shells of the hollow silica spheres had nanopores with average diameters of 0.92-1.25 nm. When the silica-coated Fe3O4 core-shell composites were prepared at a high pH value or with a low mole ratio of Na2SiO3 to Fe3O4, the resulting hollow silica spheres consisted of highly porous shells. When the silica-coated Fe3O4 core-shell composites were prepared with a high mole ratio of Na2SiO3 to Fe3O4, the resulting hollow silica spheres had large diameters and thick shells. The release rate of herbicide, ammonium glyphosate, could be tuned by using hollow silica spheres with different shell thicknesses.Chun Liu Aili Wang Hengbo Yin Yutang Shen Tingshun Jiang 2012Particuology2012,10,3:5
16Absolute configuration of Buagafuran:An experimental and theoretical electronic circular dichroism study显示文摘Buagafuran is a novel drug candidate derived from natural product.Its absolute configuration has been confirmed by electronic circular dichroism combined with modern quantum-chemical calculation using time-dependent density functional theory.The predicted UV absorbance peak is underestimated by several nanometers compared with the experimental data.The applicability of empirical rule for the C=C-C-O system in Buagafuran has also been discussed.Our results show that electronic circular dichroism could be a useful tool for the absolute configuration assignment of chiral drugs,especially for the oily or semisolid substances,whose crystal structures are impossible to obtain.Li Li Chun Li Yi-Kang Si Da-Li Yin 2013Chinese Chemical Letters2013,24,6:5
17Effect of Na Fe EDTA-Fortified Soy Sauce on Anemia Prevalence in China: A Systematic Review and Meta-analysis of Randomized Controlled Trials显示文摘Objective To assess the effect of sodium iron ethylenediaminetetraacetate(Na Fe EDTA)-fortified soy sauce on anemia prevalence in the Chinese population. Methods A systematic review was performed to identify potential studies by searching the electronic databases of Pub Med, Cochrane Library, WHO Library, High Wire, CNKI, and other sources. The selection criteria included randomized controlled trials that compared the efficacy of Na Fe EDTA-fortified soy sauce with that of non-fortified soy sauce. Anemia rates and hemoglobin levels were the outcomes of interest. Inclusion decisions, quality assessment, and data extraction were performed by two reviewers independently. A total of 16 studies met the inclusion criteria for anemia rate analysis, of which 12 studies met the inclusion criteria for hemoglobin analysis. All included studies assessed the effect of Na Fe EDTA-fortified soy sauce on anemia rates and hemoglobin concentrations. Results After the intervention, the hemoglobin concentration increased and anemia rates decreased significantly as compared with the non-fortified soy sauce groups. For anemia rates, data from 16 studies could be pooled, and the pooled estimate odds ratio was 0.25(95% CI 0.19-0.35). For hemoglobin concentrations, data from 12 studies could be pooled, and the pooled weighted mean difference was 8.81 g/L(95% CI 5.96-11.67). Conclusion Na Fe EDTA-fortified soy sauce has a positive effect on anemia control and prevention in the at-risk population.HUO Jun Sheng YIN Ji Yong SUN Jing HUANG Jian LU Zhen Xin REGINA Moench-Pfanner CHEN Jun Shi CHEN Chun Ming 2015Biomedical and Environmental Sciences2015,28,11:5
18An Anomalous Behavior Detection Model in Cloud Computing显示文摘This paper proposes an anomalous behavior detection model based on cloud computing. Virtual Machines(VMs) are one of the key components of cloud Infrastructure as a Service(Iaa S). The security of such VMs is critical to Iaa S security. Many studies have been done on cloud computing security issues, but research into VM security issues, especially regarding VM network traffic anomalous behavior detection, remains inadequate.More and more studies show that communication among internal nodes exhibits complex patterns. Communication among VMs in cloud computing is invisible. Researchers find such issues challenging, and few solutions have been proposed—leaving cloud computing vulnerable to network attacks. This paper proposes a model that uses Software-Defined Networks(SDN) to implement traffic redirection. Our model can capture inter-VM traffic, detect known and unknown anomalous network behaviors, adopt hybrid techniques to analyze VM network behaviors, and control network systems. The experimental results indicate that the effectiveness of our approach is greater than 90%, and prove the feasibility of the model.Xiaoming Ye Xingshu Chen Haizhou Wang Xuemei Zeng Guolin Shao Xueyuan Yin Chun Xu 2016Tsinghua Science and Technology2016,21,3:5
19Mesoporous silica rods with cone shaped pores modulate inflammation and deliver BMP-2 for bone regeneration显示文摘Biomaterials with suitable osteoimmunomodulation properties and ability to deliver osteoinductive biomolecules,such as bone morphogenetic proteins,are desired for bone regeneration.Herein,we report the development of mesoporous silica rods with large cone-shaped pores(MSR-CP)to load and deliver large protein drugs.It is noted that those cone-shaped pores on the surface modulated the immune response and reduced the pro-inflammatory reaction of stimulated macrophage.Furthermore,bone morphogenetic proteins 2(BMP-2)loaded MSR-CP facilitated osteogenic differentiation and promoted osteogenesis of bone marrow stromal cells.In vivo tests confirmed BMP-2 loaded MSR-CP improved the bone regeneration performance.This study provides a potential strategy for the design of drug delivery systems for bone regeneration.Chun Xu Lan Xiao Yuxue Cao Yan He Chang Lei Yin Xiao Wujin Sun Samad Ahadian Xueting Zhou Ali Khademhosseini Qingsong Ye 2020Nano Research2020,13,9:5
20TiO_2/Schwertmannite nanocomposites as superior co-catalysts in heterogeneous photo-Fenton process显示文摘The heterogeneous photo-Fenton reaction is an effective technique in combating organic contaminants for both soil and water remediation,and extensive studies have focused on enhancing its efficiency and reducing its costs.In this work,we developed novel photoFenton catalysts by simply milling commercially available TiO_2(P25)with Schwertmannite(Sh),a natural iron-oxyhydroxysulfate nanomineral.We expect that the photo-generated electrons from TiO_2could continuously migrate to Sh,which then could enhance the separation of electron-hole pairs on TiO_2and accelerate the reduction of Fe(III)to Fe(II)on Sh,leading to high degradation efficiency of the target organic contaminants.SEM and TEM results showed the distribution of TiO_2on Sh surface for the nanocomposites(TiO_2/Sh).Under simulated sunlight irradiation,the much higher content of Fe(II)was determined on TiO_2/Sh than on Sh via a common method in the iron ore,and the consumption of H_2O_2and the production of·OH were more significant in the TiO_2/Sh system than those in the TiO_2and Sh systems.These results well support our hypothesis that the photo-generated electrons could migrate from TiO_2to Sh on the composites,and can also explain the much higher degradation efficiency of Rhodamine B(RhB)in the TiO_2/Sh system.Besides,TiO_2/Sh had lower Fe dissolution as compared with Sh,and retained high catalytic stability after four repeated cycles.Above merits of the TiO_2/Sh composites,in combining with their simple synthesis method and low-cost property,indicated that they should have promising applications as heterogeneous photo-Fenton catalysts.Yanping Zhu Chun Zeng Runliang Zhu Yin Xu Xingyan Wang Huijun Zhou Jianxi Zhu Hongping He 2019Journal of Environmental Sciences2019,31,6:5
