| 1 | BMI, WC, WHtR, VFI and BFI: Which Indictor is the Most Efficient Screening Index on Type 2 Diabetes in Chinese Community Population显示文摘Objective Obesity is a major risk factor for type 2 diabetes, many indexes can be used to describes obesity and predict diabetes. This research attempts to identify the best indicator of obesity to screening diabetes in Chinese population. Methods A cross-sectional data of 8121 subjects aged 35-60 years were included in this research belongs to the Diabetes Appropriate Technology Intervention Study. Anthropometric indicators including body weight, height, waist circumferences (WC), body fat index (BFI) and visceral fat index (VFI) and blood biochemical indicators after an overnight fast [fasting blood glucose, total cholesterol, high-density lipoprotein (HDL) cholesterol, and triacylglycerol] were measured. BMI (body mass index) and Weight to Height Ratio was calculated. Results Subjects with obesity had a higher risk of physician diagnosed diabetes (OR=2.50, 95% CI 1.83-3.43), new diagnosed diabetes (OR=4.23, 95% CI 2.91-6.15) and pre-diabetes (OR=1.75, 95% CI 1.31-2.34) compared to those with normal Body mass index (BMI). There was a significant trend of increased risk of all diabetes status with increased waist circumference (WC). The waist-to-height ratio (WHtR) yielded the most significant association with new diagnosed diabetes and physician diagnosed diabetes than other indices. Conclusion Central obesity is significantly correlated with diabetes. VFI was most correlated with pre-diabetes while WHtR is an efficient screening index than BMI and WC in Chinese community diabetes screening. | MI Sheng Quan YIN Peng HU Nan LI Jian Hong CHEN Xiao Rong CHEN Bo YAN Liu Xia ZHAO Wen Hua | 2013 | Biomedical and Environmental Sciences2013,26,6: | 20 |
| 2 | Neutrophil extracellular traps mediate the crosstalk between glioma progression and the tumor microenvironment via the HMGB1/RAGE/IL-8 axis显示文摘Objective:Neutrophil extracellular traps(NETs)produced by tumor-infiltrating neutrophils(TINs)are associated with poor prognosis in patients with several types of cancer.However,the mechanisms underlying the involvement of NETs in glioma progression remain largely unknown.This study aimed to elucidate the roles of NETs in biological processes that drive the crosstalk between glioma progression and the tumor microenvironment.Methods:Neutrophil infiltration and NETs formation were investigated in glioma tissue through immunohistochemistry,and their relationships with clinicopathological features and outcomes were statistically evaluated.The effects of NETs on glioma cell progression were studied in a co-culture system.In vivo and in vitro experiments validated the reactive oxygen species activity and cytokine production of TINs,as well as the ERK signaling pathway activation and the metastasis of gliomas.Results:Neutrophil infiltration and NETs formation were induced in high-grade glioma compared with low-grade glioma.NETs induced by TINs were determined to be an oncogenic marker of high-grade gliomas and to be involved in cell proliferation and invasion.NETs overproduction promoted glioma cell proliferation,migration,and invasion.Furthermore,HMGB1 was found to bind to RAGE and activate the NF-κB signaling pathway in vitro.In addition,NETs stimulated the NF-κB signaling pathway,thus promoting IL-8 secretion in glioblastoma.Subsequently,IL-8 recruited neutrophils which in turn mediated NETs formation via the PI3 K/AKT/ROS axis in TINs.Conclusions:Our results suggest that NETs produced by TINs mediate the crosstalk between glioma progression and the tumor microenvironment by regulating the HMGB1/RAGE/IL-8 axis.Targeting NETs formation or IL-8 secretion may be an effective approach to inhibit glioma progression. | Caijun Zha Xiangqi Meng Lulu Li Shan Mi Da Qian Ziwei Li Pengfei Wu Shaoshan Hu Shihong Zhao Jinquan Cai Yanhong Liu | 2020 | Cancer Biology & Medicine2020,17,1: | 19 |

| 7 | Uptake of HIV Self-testing among Men Who have Sex with Men in Beijing, China: a Cross-sectional Study显示文摘Objective To examine HIV self-testing uptake and its determinates among men who have sex with men(MSM) in Beijing, China. Methods A cross-sectional online survey was conducted in Beijing, China in 2016. Participants were users of a popular Chinese gay networking application and had an unknown or negative HIV status. Univariate and multivariate logistic regression analyses were conducted to examine factors associated with HIV self-testing based on adjusted odds ratio(AOR) and 95% confidence interval(CI). Results Among the 5,996 MSM included in the study, 2,383(39.7%) reported to have used HIV self-testing kits. Willingness to use an HIV self-test kit in the future was expressed by 92% of the participants. High monthly income(AOR = 1.49; CI = 1.10-2.02; P = 0.010), large number of male sex partners(≥ 2: AOR = 1.24; CI = 1.09-1.43; P = 0.002), sexual activity with commercial male sex partners(≥ 2: AOR = 1.94; CI = 1.34-2.82; P = 0.001), long-term drug use(AOR = 1.42; CI = 1.23-1.62; P < 0.001), and long-term HIV voluntary counseling and testing(VCT) attendance(AOR = 3.62; CI = 3.11-4.22; P < 0.001) were all associated with increased odds of HIV self-testing uptake. Conclusion The nearly 40% rate of HIV self-testing uptake among MSM in our sample was high. In addition, an over 90% willingness to use kits in the future was encouraging. HIV self-testing could be an important solution to help China achieve the global target of having 90% of all people living with HIV diagnosed by 2020. | REN Xian Long WU Zun You MI Guo Dong MCGOOGAN Jennifer ROU Ke Ming ZHAO Yan | 2017 | Biomedical and Environmental Sciences2017,30,6: | 13 |

| 9 | Organic thin-film solar cells:Devices and materials显示文摘In recent years, the performance of organic thin-film solar cells has gained rapid progress, of which the power conversion efficiencies (ηp) of 3%-5% are commonly achieved, which were difficult to obtain years ago and are improving steadily now. The ηp of 7.4% was achieved in the year 2010, and ηp of 9.2% was disclosed and confirmed at website of Mitsubishi Chemical in April, 2011. The promising future is that the ηp of 10% is achievable according to simulation results. Apparently, these are attributed to material innovations, new device structures, and also the better understanding of device physics. This article summarizes recent progress in organic thin-film solar cells related to materials, device structures and working principles. In the device functioning part, after each brief summary of the working principle, the methods for improvements, such as absorption increment, organic/electrode interface engineering, morphological issues, are addressed and summarized accordingly. In addition, for the purpose of increasing exciton diffusion efficiency, the benefit from triplet exciton, which has been proposed in recent years, is highlighted. In the active material parts, the chemical nature of materials and its impact on device performance are discussed. Particularly, emphasis is given toward the insight for better understanding device physics as well as improvements in device performance either by development of new materials or by new device architecture. | LI ZhiGang1, ZHAO XinYan2, LI Xin1,2, GAO ZhiQiang1, MI BaoXiu1 & HUANG Wei2 1Jiangsu Engineering Centre for Flat-Panel Displays & Solid-state Lighting and School of Materials Science & Engineering, Nanjing University of Posts & Telecommunications, Nanjing 210046, China 2Key Laboratory for Organic Electronics & Information Displays (KLOEID) Institute of Advanced Materials (IAM), Nanjing University of Posts & Telecommunications, Nanjing 210046, China | 2012 | Science China Chemistry2012,55,4: | 9 |

| 11 | Regulation of Survivin and CDK4 by Epstein-Barr virus encoded latent mem-brane protein 1 in nasopharyngeal carcinoma cell lines显示文摘Latent membrane protein 1 (LMP1), an important protein encoded by Epstein Barr virus (EBV), has been implied to link with the pathogenesis of nasopharyngeal carcinoma (NPC). Its dual effects of increasing cell proliferation and inhibiting cell apoptosis have been confirmed. In this study, we showed that the expression of Survivin and CDK4 protein in CNE-LMP1, a LMP1 positive NPC epithelial cell line, is higher than in LMP1 negative NPC epithelial cell line- CNE1, and the expression is LMP1 dosage-dependent. Although it was reported that Survivin specifically expressed in cell cycle G2/M phase, our studies suggested that LMP1 could promote the expression of Survivin in G0/G1, S and G2/ M phase. It also showed that Survivin and CDK4 could be accumulated more in the nuclei triggered by LMP1. More interestingly, Survivin and CDK4 could form a protein complex in the nuclei of CNE-LMP1 rather than in that of CNE1, which demonstrated that the interaction between these two proteins could be promoted by LMP1. These results strongly suggested that the role of LMP1 in the regulation of Survivin and CDK4 may also shed some light on the mechanism research of LMP1 in NPC. | Mi Dan AI Li Li LI Xiao Rong ZHAO Yong WU Jian Ping GONG Ya CAO | 2005 | Cell Research2005,15,10: | 8 |
| 12 | Polybrominated diphenyl ethers in chicken tissues and eggs from an electronic waste recycling area in southeast China显示文摘The levels and distributions of polybrominated diphenyl ethers(PBDEs) in chicken tissues from an electronic waste(e-waste) recycling area in southeast China were investigated.Human dietary intake by local residents via chicken muscle and eggs was estimated.The mean PBDEs concentrations in tissues ranged from 15.2 to 3138.1 ng/g lipid weight(lw) and in egg the concentration was 563.5 ng/g lw.The results showed that the level of total PBDEs(ΣPBDEs) in the chicken tissue was 2-3 orders of magnitude higher than those reported in the literature.The large difference of ΣPBDEs concentrations between tissues confirmed that the distribution of PBDEs in tissues depend on tissue-specificity rather than the 'lipid-compartment'.BDE-209 was the predominant congener(82.5%-94.7% of ΣPBDEs) in all chicken tissues except in brain(34.7% of ΣPBDEs),which indicated that deca-BDE(the major commercial PBDE formulation comprising 65%-70% of total production) was major pollution source in this area and could be bioaccumulated in terrestrial animals.The dietary PBDEs intake of the local residents from chicken muscle and egg,assuming only local bred chickens and eggs were consumed,ranged from 2.2 to 22.5 ng/(day·kg body weight(bw)) with a mean value of 13.5 ng/(day·kg bw),which was one order of magnitude higher than the value reported in previous studies for consumption of all foodstuffs. | Xiaofei Qin Zhanfen Qin Yan Li Yaxian Zhao Xijuan Xia Shishuai Yan Mi Tian Xingru Zhao Xiaobai Xu Yongjian Yang | 2011 | Journal of Environmental Sciences2011,23,1: | 8 |
| 13 | Efficacy of a Chinese herbal formula on hepatitis B e antigenpositive chronic hepatitis B patients显示文摘BACKGROUND No guideline recommends antiviral therapy for hepatitis B e antigen(HBeAg)-positive chronic hepatitis B patients with persistently normal alanine aminotransferase levels and a high hepatitis B virus(HBV)DNA viral load.AIM To evaluate the feasibility and safety of a Chinese herbal formula as a therapeutic option for chronic HBV infection.METHODS In total,395 patients(30–65 years old)with confirmed HBeAg-positive chronic hepatitis B infection and persistently normal alanine aminotransferase were randomized to receive either Chinese herbal formula or placebo for 96 wk.Endpoints to evaluate therapeutic efficacy included:(1)HBV DNA levels decreased to less than 4 log10 IU/mL at weeks 48 and 96;and(2)HBeAg clearance and seroconversion rates at weeks 48 and 96.RESULTS HBV DNA levels≤4 log10 IU/mL were 10.05%at week 48 and 18.59%at week 96 in the treatment group.The HBeAg clearance and conversion rates were 8.54%and 8.04%at week 48 and 16.08%and 14.57%at week 96,respectively.However,HBV DNA levels≤4 log10 IU/mL were 2.55%and 2.55%at weeks 48 and 96,respectively,and the HBeAg clearance rates were 3.06%and 5.61%at weeks 48 and 96,respectively,in the control group.The quantitative hepatitis B surface antigen and HBeAg levels at baseline and changes during the treatment period as well as the alanine aminotransferase elevation at weeks 12 and 24 were strong predictors of HBeAg clearance.CONCLUSION High rates of HBV DNA reduction,HBeAg clearance and seroconversion could be achieved with Chinese herbal formula treatments,and the treatments were relatively safe for HBeAg-positive chronic hepatitis B-infected patients with persistently normal alanine aminotransferase.The ability of the compound to modulate host immune function probably contributed to this effect. | Yu-Feng Xing Chun-Shan Wei Tian-Ran Zhou Dan-Ping Huang Wei-Chao Zhong Bin Chen Hua Jin Xiao-Yu Hu Zhi-Yun Yang Qing He Kai-Ping Jiang Jun-Min Jiang Zhen-Bin Hu Xin Deng Fan Yang Feng-Yi Li Gang Zhao Li-Chun Wang Yu-Qiang Mi Zuo-Jiong Gong Peng Guo Jian-Hua Wu Wei-Qun Shi Hong-Zhi Yang Da-Qiao Zhou Guang-Dong Tong | 2020 | World Journal of Gastroenterology2020,26,30: | 7 |
| 14 | 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 |
| 15 | Integration of SAR Polarimetric Features and Multi-spectral Data for Object-Based Land Cover Classification显示文摘An object-based approach is proposed for land cover classification using optimal polarimetric parameters.The ability to identify targets is effectively enhanced by the integration of SAR and optical images.The innovation of the presented method can be summarized in the following two main points:①estimating polarimetric parameters(H-A-Alpha decomposition)through the optical image as a driver;②a multi-resolution segmentation based on the optical image only is deployed to refine classification results.The proposed method is verified by using Sentinel-1/2 datasets over the Bakersfield area,California.The results are compared against those from pixel-based SVM classification using the ground truth from the National Land Cover Database(NLCD).A detailed accuracy assessment complied with seven classes shows that the proposed method outperforms the conventional approach by around 10%,with an overall accuracy of 92.6%over regions with rich texture. | Yi ZHAO Mi JIANG Zhangfeng MA | 2019 | Journal of Geodesy and Geoinformation Science2019,2,4: | 7 |
| 16 | Ecotoxicological effects of mixed pollutants resulted from e-wastes recycling and bioaccumulation of polybrominated diphenyl ethers in Chinese loach(Misgurnus anguillicaudatus)显示文摘To understand potential ecotoxicological effects of electrical and electronic equipment waste (e-waste) recycling and polybrominated diphenyl ethers (PBDEs) bioaccumulation in loaches, a semi-field experiment using Chinese loach (Misgurnus anguillicaudatus) as experimental fish was performed. Larval loaches were kept in net-cage for three months in an e-wastes recycling site and a reference site in Southeastern China. There was significant difference of the survival rate between the loaches from the e-wastes recycling site (27%, 19/70) and from reference site (70%, 49/70). Histopathological responses were also found in all the livers examined in loaches from the e-wastes recycling site. These results showed that mixed pollutants resulted from e-wastes recycling led to ecotoxicological effects on loaches. The bioaccumulation of polybrominated diphenyl ethers (PBDEs), the main pollutants in e-waste, in loaches was also studied, the mean concentration of total PBDEs in sediment was 6726.17 ng/g wet weight and in water samples was 4.08 ng/L (dissolved phase). BDE 209 was the dominant congener in sediment and with relatively high concentration in water. Relatively low concentration of BDE 209 (less than 0.01% of total PBDEs) and high concentration of BDE47 (up to 39.34% of total PBDEs) were detected in loaches. | QIN Xiaofei XIA Xijuan LI Yan ZHAO Yaxian YANG Zhongzhi FU Shan TI-AN Mi ZHAO Xingru QIN Zhanfen XU Xiaobai YANG Yongjian | 2009 | Journal of Environmental Sciences2009,21,12: | 6 |
| 17 | Recent progress in the numerical modeling for organic thin film solar cells显示文摘Device modeling is constructive in finding the dependency of devices efficiency on structure parameters and material properties. For the sake of looking into the physics mechanism of organic solar cells (OSCs), as well as predicting their maximum attainable efficiency, numerical modeling is widely utilized to simulate the behavior of OSCs. Although some indispensable parameters are neglected or hypothesized because of inexplicitness in simulation models for OSCs, numerical modeling can describe the kinetic process in OSCs intuitively. This paper summarizes the optical/electrical models in the BHJ solar cell, as well as addresses their corresponding development in recent years on the basis of device physics and its working principle. Applications of numerical modeling and comments on modeling results are summarized. Meanwhile, precision and open questions about every model are discussed. | ZHAO XinYan MI BaoXiu GAO ZhiQiang HUANG Wei | 2011 | Science China(Physics,Mechanics & Astronomy)2011,54,3: | 6 |
| 18 | Texture evolution of commercial pure Ti during cold rolling and recrystallization annealing显示文摘X-ray diffraction (XRD) was employed to analyze the texture evolution of commercial pure (CP) Ti during cold rolling and re-crystallization annealing. The texture components were measured by electron backscattered diffraction (EBSD) after recrystallization an-nealing. The CP Ti tends to form a texture with the basal pole tilted 30°-40° away from the normal direction toward the transverse direction. The texture of the initial hot-rolled plate can be classified into three kinds, i.e., the pyramid texture and , the basal plane texture , and the stronger prism texture . After cold rolling and annealing (700°C, 60 min), the main texture components are the cold-rolled texture and the recrystallized texture . The texture is in-herited from the texture of the initial hot-rolled plate with the decrease of orientation density gradually. The volume contents of the cold-rolled texture and the recrystallized texture are calculated by EBSD. After recrystallization annealing, the specimen is rich in the recrystallized texture and inherits some of texture components from the cold-rolled texture. When the annealing time is prolonged, the anisotropic value decreases. | Hai-tao Jiang Ji-xiong Liu Zhen-li Mi Ai-min Zhao Yan-jun Bi | 2012 | International Journal of Minerals,Metallurgy and Materials2012,19,6: | 6 |
| 19 | Development and in vitro study of a bi-specific magnetic resonance imaging molecular probe for hepatocellular carcinoma显示文摘BACKGROUND Hepatocellular carcinoma(HCC)ranks second in terms of cancer mortality worldwide.Molecular magnetic resonance imaging(MRI)targeting HCC biomarkers such as alpha-fetoprotein(AFP)or glypican-3(GPC3)offers new strategies to enhance specificity and help early diagnosis of HCC.However,the existing iron oxide nanoparticle-based MR molecular probes singly target AFP or GPC3,which may hinder their efficiency to detect heterogeneous micro malignant HCC tumors<1 cm(MHCC).We hypothesized that the strategy of double antibody-conjugated iron oxide nanoparticles which simultaneously target AFP and GPC3 antigens may potentially be used to overcome the tumor heterogeneity and enhance the detection rate for MRI-based MHCC diagnosis.AIM To synthesize an AFP/GPC3 double antibody-labeled iron oxide MRI molecular probe and to assess its impact on MRI specificity and sensitivity at the cellular level.METHODS A double antigen-targeted MRI probe for MHCC anti-AFP-USPIO-anti-GPC3(UAG)was developed by simultaneously conjugating AFP andGPC3 antibodies to a 5 nm ultra-small superparamagnetic iron oxide nanoparticle(USPIO).At the same time,the singly labeled probes of anti-AFP-USPIO(UA)and anti-GPC3-USPIO(UG)and non-targeted USPIO(U)were also prepared for comparison.The physical characterization including morphology(transmission electron microscopy),hydrodynamic size,and zeta potential(dynamic light scattering)was conducted for each of the probes.The antigen targeting and MRI ability for these four kinds of USPIO probes were studied in the GPC3-expressing murine hepatoma cell line Hepa1-6/GPC3.First,AFP and GPC3 antigen expression in Hepa1-6/GPC3 cells was confirmed by flow cytometry and immunocytochemistry.Then,the cellular uptake of USPIO probes was investigated by Prussian blue staining assay and in vitro MRI(T2-weighted and T2-map)with a 3.0 Tesla clinical MR scanner.RESULTS Our data showed that the double antibody-conjugated probe UAG had the best specificity in targeting Hepa1-6/GPC3 cells expressing AFP and GPC3 antigens compared with single antibody-conjugated and unconjugated USPIO probes.The iron Prussian blue staining and quantitative T2-map MRI analysis showed that,compared with UA,UG,and U,the uptake of double antigen-targeted UAG probe demonstrated a 23.3%(vs UA),15.4%(vs UG),and 57.3%(vs U)increased Prussian stained cell percentage and a 14.93%(vs UA),9.38%(vs UG),and 15.3%(vs U)reduction of T2 relaxation time,respectively.Such bi-specific probe might have the potential to overcome tumor heterogeneity.Meanwhile,the coupling of two antibodies did not influence the magnetic performance of USPIO,and the relatively small hydrodynamic size(59.60±1.87 nm)of double antibodyconjugated USPIO probe makes it a viable candidate for use in MHCC MRI in vivo,as they are slowly phagocytosed by macrophages.CONCLUSION The bi-specific probe presents enhanced targeting efficiency and MRI sensitivity to HCC cells than singly-or non-targeted USPIO,paving the way for in vivo translation to further evaluate its clinical potential. | Xiao-Hong Ma Shuang Wang Si-Yun Liu Kun Chen Zhi-Yuan Wu Deng-Feng Li Yong-Tao Mi Long-Bin Hu Zhong-Wei Chen Xin-Ming Zhao | 2019 | World Journal of Gastroenterology2019,25,24: | 5 |
| 20 | The pathologic relevance of metabolic criteria in patients with biopsy-proven nonalcoholic fatty liver disease and metabolic dysfunction associated fatty liver disease:A multicenter cross-sectional study in China显示文摘Background:This study aimed to assess the association between metabolic syndrome(Met S)and severity of nonalcoholic fatty liver disease(NAFLD),and to discuss the pathological relevance of the diagnostic criteria in metabolic(dysfunction)associated fatty liver disease(MAFLD).Methods:This was a multicenter,cross-sectional study.Patients with NAFLD confirmed by liver biopsy were enrolled between July 2016 and December 2018 from 14 centers across the mainland of China.Anthropometric and metabolic parameters were collected to assess the pathological relevance.Results:Of 246 enrolled patients with NAFLD,150(61.0%)had the comorbidity of Met S.With the increase of metabolic components,the proportions of nonalcoholic steatohepatitis(NASH)and significant fibrosis were notably increased.The comorbid three metabolic components significantly increased the proportion of NASH,and further increase of metabolic components did not increase the proportion of NASH.However,the increase of metabolic components was parallel to the increase of the proportion of liver fibrosis.Among the 246 patients,239(97.2%)met the diagnostic criteria of MAFLD.Although non-MAFLD patients had less NASH,they present with similar proportion of significant fibrosis and cirrhosis.In the diagnostic criteria of MAFLD,BMI≥23 kg/m2 was related to NASH(Mantel-Haenszel Common Estimate OR:2.975;95%CI:1.037–8.538;P=0.043),and T2 DM was related to significant fibrosis(Mantel-Haenszel Common Estimate OR:2.531;95%CI:1.388–4.613;P=0.002).The homeostasis model assessment of insulin resistance(HOMA-IR)≥2.5 was the most significant factor for NASH(OR:4.100;95%CI:1.772–9.487;P=0.001)and significant factor for liver fibrosis(OR:2.947;95%CI:1.398–6.210;P=0.004)after the adjustments of the BMI and diabetes.Conclusions:Metabolic dysregulations are important risk factors in NAFLD progression.The insulin resistance status may play a predominant role in the progression in MAFLD patients. | Rui-Xu Yang Zheng-Sheng Zou Bi-Hui Zhong Hong Deng Fang-Ping He Jun-Ping Shi Cai-Yan Zhao Yu-Qiang Mi Yong-Jian Zhou Fu-Sheng Di Rui-Dan Zheng Qin Du Jia Shang Branko Popovic Jin Jun Chen Jian-Gao Fan | 2021 | Hepatobiliary & Pancreatic Diseases International2021,20,5: | 5 |
