| 5 | Fe2N nanoparticles boosting FeNx moieties for highly efficient oxygen reduction reaction in Fe-N-C porous catalyst显示文摘Replacing Pt-based electrocatalysts for the oxygen reduction reaction (ORR) with high performance and low-cost non-precious metal catalysts is crucial for the commercialization of fuel cells.Herein,we present a highly efficient Fe-N-C porous ORR electrocatalyst with FeNx moieties promoted by Fe2N nanoparticles derived from Fe-doped zeolitic imidazolate framework.The best-performing Fe-N-C/HPC-NH3 catalyst exhibits a superior ORR activity with an onset (E0) and half-wave (E1/2) potential of 0.945 and 0.803 V (RHE),respectively,which is comparable to those of the commercial Pt/C in acidic media.Probing and acid-leaching experiments prove that FeNx moieties play an important role in the ORR and the Fe2N can further improve the ORR activity.Density functional theory calculation reveals a synergistic effect that the existence of Fe2N weakens the adsorption of ORR intermediates on active sites and lowers the reaction free energy of the potential limiting step,thus facilitating the ORR.Both experimental evidence and theoretical analysis for the enhancement of ORR activity by Fe2N decoration in Fe-N-C catalyst might inspire a new strategy for rational design of high performance non-precious metal catalysts. | Xiao Liu Hong Liu Chi Chen Liangliang Zou Yuan Li Qing Zhang Bo Yang Zhiqing Zou Hui Yang | 2019 | Nano Research2019，12，7： | 14 |

| 9 | 碎裂QRS波联合TIMI危险评分预测急性心肌梗死患者的短期预后(英文)显示文摘目的:探讨碎裂QRS波(fQRS)联合心肌梗死溶栓治疗临床试验(TIMI)危险评分对急性心肌梗死(AMI)患者短期预后的评估价值。创新点:TIMI危险评分常用于AMI患者入院即刻的风险评估,TIMI评分<4分的患者被评定为中危组。本研究发现,无论TIMI评分如何,出现fQRS而未行经皮冠状动脉介入治疗(PCI)的患者,其死亡率均显著升高。fQRS联合TIMI危险评分更利于AMI患者的预后评估,TIMI评分<4分但同时合并fQRS的患者,可以从早期PCI介入治疗获益。方法:回顾300例AMI患者的临床资料及院内诊治经过,记录分析患者fQRS出现的时间、部位及其他临床转归,评价fQRS联合TIMI危险评分与患者临床预后的关系。结论:(1)fQRS联合TIMI危险评分可提高恶性心律失常、左室收缩功能不全(LVSD)和死亡预测的敏感度和特异度;(2)fQRS阳性的AMI患者,进行早期血运重建可降低患者心血管事件发生率,fQRS可能作为TIMI评分<4分患者早期介入治疗的指征。 | Qin-hui SHENG Chih Chi HSU Jian-ping LI Tao HONG Yong HUO | 2018 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2018，19，5： | 8 |
| 10 | An-Luo-Hua-Xian Pill Improves the Regression of Liver Fibrosis in Chronic Hepatitis B Patients Treated with Entecavir显示文摘Background and Aims:Chronic hepatitis B(CHB)can cause liver fibrosis and lead to cirrhosis and cancer.As the effectiveness of antiviral therapy to reverse liver fibrosis is limited,We aimed to evaluate the effect of An-Luo-Hua-Xian pill(ALHX)on fibrosis regression in CHB patients treated with entecavir(ETV).Methods:Treatment-naïve patients with CHB were randomly treated with ETV alone or combined with ALHX(ETV+ALHX)between October 1,2013 and December 31,2020.Demographic,laboratory,and liver histology data before and after 78 weeks of treatment were collected.The Ishak fibrosis score(F)was used and fibrosis regression required a decrease in F of≥1 after treatment.Results:A total of 780 patients were enrolled,and 394 with a second liver biopsy after treatment were included in the per-protocol population,132 in ETV group and 262 in ETV+ALHX group.After 78 weeks of treatment,the fibrosis regression rate in the ETV+ALHX group was significantly higher than that of the ETV group at baseline F≥3 patients:124/211(58.8%)vs.45/98(45.9%),p=0.035.The percentage of patients with a decreased liver stiffness measurement(LSM)was higher in the ETV+ALHX group:156/211(73.9%)vs.62/98(63.%),p=0.056.Logistic regression analysis showed that ETV combined with ALHX was associated with fibrosis regression[odds ratio(OR)=1.94,p=0.018],and a family history of hepatocellular carcinoma was on the contrary.(OR=0.41,p=0.031).Conclusions:ETV combined with ALHX increased liver fibrosis regression in CHB patients. | Yi-Qi Liu Chi Zhang Jia-Wen Li Li-Hua Cao Zhan-Qing Zhang Wei-Feng Zhao Qing-Hua Shang Da-Zhi Zhang An-Lin Ma Qing Xie Hong-Lian Gui Guo Zhang Ying-Xia Liu Jia Shang Shi-Bin Xie Jun Li Xu-Qing Zhang Zhi-Qiang Zou Yu-Ping Chen Zong Zhang Ming-Xiang Zhang Jun Cheng Fu-Chun Zhang Li-Hua Huang Jia-Bin Li Qing-Hua Meng Hai-Bin Yu Yu-Qiang Mi Yan-Zhong Peng Zhi-Jin Wang Li-Ming Chen Fan-Ping Meng Wan-Hua Ren Lang Bai Yi-Lan Zeng Rong Fan Xian-Zhi Lou Wei-Feng Liang Hui Liu Hui Zhuang Hong Zhao Gui-Qiang Wang | 2023 | Journal of Clinical and Translational Hepatology2023，11，2： | 7 |
| 11 | Untreated Prior Pulmonary Tuberculosis Adversely Affects Pregnancy Outcomes in Infertile Women Undergoing in vitro Fertilization and Embryo Transfer: A Large Retrospective Cohort Study显示文摘Objective Prior pulmonary tuberculosis(PTB) on chest X-ray(CXR) was commonly found in infertile patients receiving examinations before in vitro fertilization and embryo transfer(IVF-ET). It was unclear whether untreated PTB would affect pregnancy outcomes after IVF-ET.Method We conducted a retrospective cohort study of 14,254 infertile patients who had received IVFET at Peking University Third Hospital in 2017. Prior PTB was defined as the presence of signs suggestive of old or inactive PTB on CXR, with or without a clinical TB history. Patients who had prior PTB on CXR but had not received a clinical diagnosis and anti-TB therapy were included for analysis. Live birth,clinical pregnancy, and miscarriage rates were compared between the untreated PTB and non-PTB groups.Results The untreated PTB group had significantly lower clinical pregnancy(31.7% vs. 38.1%) and live birth(23.8% vs. 30.6%) rates than the non-PTB group(both P < 0.001). Multivariate analysis revealed that untreated PTB was a risk factor for decreased live birth rate [odds ratio(OR), 0.80;95% confidence interval(CI), 0.66–0.98;P = 0.028] in all patients and for increased miscarriage(OR, 4.19;95% CI,1.69–10.39;P = 0.002) and decreased live birth(OR, 0.45;95% CI, 0.24–0.83;P = 0.011) rates in patients with unexplained infertility.Conclusions Untreated PTB was associated with adverse pregnancy outcomes after IVF-ET, especially in patients with unexplained infertility, highlighting the clinical significance of PTB in this specific patient population. | GAI Xiao Yan CHI Hong Bin ZENG Lin CAO Wen Li CHEN Li Xue ZHANG Chen LU Ming NING Lan Ding CHANG Chun ZHANG Wei Xia LIU Ping LI Rong SUN Yong Chang QIAO Jie | 2021 | Biomedical and Environmental Sciences2021，34，2： | 6 |
| 12 | Effect of HIV-1 Tat on Secretion of TNF-α and IL-1β by U87 Cells in AIDS Patients with or without AIDS Dementia Complex显示文摘Objective To explore the role of HIV-1 tat gene variations in AIDS dementia complex(ADC) pathogenesis.Methods HIV-1 tat genes derived from peripheral spleen and central basal ganglia of an AIDS patient with ADC and an AIDS patient without ADC were cloned for sequence analysis. HIV-1 tat gene sequence alignment was performed by using CLUSTAL W and the phylogentic analysis was conducted by using Neighbor-joining with MEGA4 software. All tat genes were used to construct recombinant retroviral expressing vector MSCV-IRES-GFP/tat. The MSCV-IRES-GFP/tat was cotransfected into 293T cells with pCMV-VSV-G and pUMVC vectors to assemble the recombinant retrovirus. After infection of gliomas U87 cells with equal amount of the recombinant retrovirus, TNF-α, and IL-1β concentrations in the supernatant of U87 cells were determined with ELISA. Results HIV-1 tat genes derived from peripheral spleen and central basal ganglia of the AIDS patient with ADC and the other one without ADC exhibited genetic variations. Tat variations and amino acid mutation sites existed mainly at Tat protein core functional area(38-47aa). All Tat proteins could induce U87 cells to produce TNF-α and IL-1β, but the level of IL-1β production was different among Tat proteins derived from the ADC patient's spleen, basal ganglia, and the non-ADC patient's spleen. The level of Tat proteins derived from the ADC patient's spleen, basal ganglia, and the non-ADC patient's spleen were obviously higher than that from the non-ADC patient's basal ganglia. Conclusion Tat protein core functional area(38-47aa) may serve as the key area of enhancing the secretion of IL-1β. This may be related with the neurotoxicity of HIV-1 Tat. | ZHAO Li PU Shuang Shuang GAO Wen Hua CHI Yuan Yuan WEN Hong Ling WANG Zhi Yu SONG Yan Yan YU Xue Jie | 2014 | Biomedical and Environmental Sciences2014，27，2： | 5 |
| 13 | Spontaneous Ureteropelvic Junction Rupture Caused by a Small Distal Ureteral Calculus显示文摘To the Editor: Spontaneous ureteral rupture is rare, and urolithiasis is the most common cause.[1,2] The underlying mechanism may be the pressure around the ureteral wall due to stone impaction or a tear during the stone passage.Smaller distal stones exert higher intraureteral pressures than do larger proximal stones because of the greater length of obstructed ureter and the smaller diameter of the distal ureter. | Chi Heon Jeon Jun Ho Kang Jin Hong Min Jung Soo Park | 2015 | Chinese Medical Journal2015，，22： | 5 |

| 15 | Characteristics and long-term prognosis of patients with rectal neuroendocrine tumors显示文摘AIM:To analyze the clinicopathologic characteristics and prognostic factors of rectal neuroendocrine tumors.METHODS:The records of 48 patients with rectal neuroendocrine tumors who were treated at the Cancer Institute and Hospital,Chinese Academy of Medical Sciences,Beijing,from March 2004 to September 2009were retrospectively reviewed.The clinicopathological data were extracted and analyzed,and patients were followed-up by telephone or follow-up letter to determine their survival status.Follow-up data were available for all 48 patients.Uni-and multivariate Cox regression analyses were performed to determine the prognostic factors significantly associated with overall survival.RESULTS:The tumors occurred mostly in the middle and lower rectum,and the most prominent symptoms experienced by patients were hematochezia and diarrhea.The median distance between the tumors andthe anal edges was 5.0±2.257 cm,and the median diameter of the tumors was 0.8±1.413 cm.The major pathological type was a typical carcinoid tumor,which accounted for 93.8%(45/48)of patients.Tumor-nodemetastasis(TNM)stagesⅠ,Ⅱ,ⅢandⅣtumors accounted for 78.8%,3.9%,9.6%and 7.7%of patients,respectively.The main treatment method,in 72.9%(35/48)of patients,was transanal extended excision.The 1-,3-and 5-year survival rates of the whole group of patients were 100%,93.7%,and 91.3%,respectively.Univariate analysis showed that age(P=0.032),tumor diameter(P<0.001),histological type(P<0.001),TNM stage(P<0.001),and surgical approach(P=0.002)were all prognostic factors.On multivariate analysis,only the pathological type was shown to be an independent prognostic factor(HR=2.797,95%CI:1.676-4.668,P=0.004).CONCLUSION:In patients with rectal neuroendocrine tumors,TNM stage Ⅰ is the most common stage found,and lymph node or distant metastases are rarely seen.The pathological type of the tumor is an independent prognostic factor. | Yihebali Chi Feng Du Hong Zhao Jin-Wan Wang Jian-Qiang Cai | 2014 | World Journal of Gastroenterology2014，20，43： | 5 |
| 16 | A space power system of free piston Stirling generator based on potassium heat pipe显示文摘The power system of a free piston Stirling generator(FPSG)based on potassium heat pipes has been developed in this paper.Thanks to the advantages of long life,high reliability,and high overall thermal efficiency,the FPSG is a promising candidate for nuclear energy,especially in space exploration.In this paper,the recent progress of FPSG based on nuclear reactor for space use was briefly reviewed.A novel FPSG weighted only 4.2 kg was designed,and one dimensional thermodynamic modeling of the FPSG using Sage software was performed to estimate its performance.The experiment results indicated that this FPSG could provide 142.4 W at a thermal-to-electric efficiency of nearly 17.4%.Besides,the power system integrated with four FPSGs and potassium heat pipes was performed and the single machine failure test was conducted.The results show that this system could provide an electrical power of 300 W at an overall thermal efficiency of 7.3%.Thus,it is concluded that this power system is feasible and will have a great prospect for future applications. | Mingqiang LIN Jian MOU Chunyun CHI Guotong HONG Panhe GE Gu HU | 2020 | Frontiers in Energy2020，14，1： | 5 |
| 17 | Significant Histologic Changes Are Not Rare in Treatment-naive Hepatitis B Patients with Normal Alanine Aminotransferase Level:A Meta-analysis显示文摘Background and Aims:Chronic hepatitis B is the main cause of liver cancer.However,the most neglected group has been treatment-naive chronic hepatitis B patients with normal alanine aminotransferase(ALT).People have tended to subjectively assume that the liver lesions of these patients are not serious and do not need antiviral treatment.However,the truth is not as optimistic as we thought.We aimed in this study to analyze the proportion of significant inflammation or fibrosis in aforementioned patients.Methods:Medline,Embase,and Cochrane Library were searched up to January 10th 2020,to identify studies of these patients with liver biopsy.The double arcsine method was used with a random-effect model to combine the proportion of significant inflammation or fibrosis.Potential heterogeneity was explored by subgroup analysis and meta-regression.Outcome of interests included the proportion of significant inflammation or fibrosis and cirrhosis.The secondary outcome was to find the risk factors of significant histological changes.Results:Nineteen eligible studies,with 2,771 participants,were included.The pooled proportion of significant inflammation or fibrosis was 35%[95%confidence interval(CI):27 to 43]and 30%(95%CI:25 to 36),respectively.The pooled proportion of cirrhosis was 3%[95%CI:1 to 5,(12 studies;1,755 participants)].In subgroup analysis,old age[vs.young(<40 years-old),44%vs.26%,p=0.012]was significantly associated with higher fibrosis stage as well as cirrhosis[vs.young(<40 years-old),4.8%vs.1.8%,p<0.001].Conclusions:About 1/3 of the treatment-naive chronic hepatitis B patients with normal ALT show significant histological changes,and some even have cirrhosis. | Chi Zhang Jia-Wen Li Zhao Wu Hong Zhao Gui-Qiang Wang | 2021 | Journal of Clinical and Translational Hepatology2021，9，5： | 4 |

| 19 | CMOS-compatible all-optical modulator based on the saturable absorption of graphene显示文摘Graphene resting on a silicon-on-insulator platform offers great potential for optoelectronic devices.In the paper,we demonstrate all-optical modulation on the graphene-silicon hybrid waveguides(GSHWs)with tens of micrometers in length.Owing to strong interaction between graphene and silicon strip waveguides with compact light confinement,the modulation depth reaches 22.7%with a saturation threshold down to 1.38 pJ per pulse and a 30-μm-long graphene pad.A response time of 1.65 ps is verified by a pump-probe measurement with an energy consumption of 2.1 pJ.The complementary metal-oxide semiconductor compatible GSHWs with the strip configuration exhibit great potential for ultrafast and broadband all-optical modulation,indicating that employing two-dimensional materials has become a complementary technology to promote the silicon photonic platform. | HONG WANG NINGNING YANG LIMIN CHANG CHAOBIAO ZHOU SHIYU LI MENG DENG ZHENWEI LI QIANG LIU CHI ZHANG ZHIYONG LI YI WANG | 2020 | Photonics Research2020，8，4： | 4 |
| 20 | Dietary nano-selenium alleviated intestinal damage of juvenile grass carp(Ctenopharyngodon idella)induced by high-fat diet:Insight from intestinal morphology,tight junction,inflammation,anti-oxidization and intestinal microbiota显示文摘In recent years,high-fat diet(HFD)has been widely applied in aquaculture,which reduces the intestinal health of cultured fish.The current study evaluated the protective effects of nano-selenium(nano-Se)on intestinal health of juvenile grass carp(Ctenopharyngodon idella)fed with HFD.A total of 135 experimental fish were fed with a regular diet(Con),a HFD(HFD)and a HFD containing nano-Se at 0.6 mg/kg(HSe)for 10 weeks.The results showed that dietary nano-Se significantly improved the survival rate and feed efficiency which were reduced by HFD in juvenile grass carp(P<0.05).Also,nano-Se(0.6 mg/kg)supplement alleviated intestinal damage caused by the HFD,thus maintaining the integrity of the intestine.Moreover,it significantly up-regulated the expression of genes related to tight junction(ZO-1,claudin-3 and occludin),anti-oxidization(GPx4a and GPx4b),and the protein of ZO-1 in the intestine of juvenile grass carp,which were depressed by the HFD(P<0.05).Furthermore,nano-Se supplementation significantly suppressed the expressions of genes related to the inflammation,including inflammatory cytokines(IL-8,IL-1β,IFN-γ,TNF-αand IL-6),signaling molecules(TLR4,p38 MAPK and NF-kB p65),and protein expression of NF-kB p65 and TNF-αin the intestine of juvenile grass carp which were induced by the HFD(P<0.05).Besides,dietary nano-Se normalized the intestinal microbiota imbalance of juvenile grass carp caused by the HFD through increasing the abundance of the beneficial bacteria,e.g.,Fusobacteria.Finally,dietary nano-Se increased the production of short chain fatty acids(SCFA)in the intestine,especially for butyric acid and caproic acid,which were negatively related to the increase of intestinal permeability and inflammation.In summary,supply of nano-Se(0.6 mg/kg)in HFD could effectively alleviate intestinal injury of juvenile grass carp by improving intestinal barrier function and reducing intestinal inflammation and oxidative stress.These positive effects may be due to the regulation of nano-Se on intestinal microbiota and the subsequently increased beneficial SCFA levels. | Sha Liu Haibo Yu Pengju Li Chi Wang Guohao Liu Xiaotian Zhang Cheng Zhang Meng Qi Hong Ji | 2022 | Animal Nutrition2022，，1： | 4 |
