| 2 | Effect of admission hypertriglyceridemia on the episodes of severe acute pancreatitis显示文摘AIM: To investigate the effect of admission hypertriglyceridemia (HTG) on the episodes of severe acute pancreatitis (SAP). METHODS: One hundred and seventy-six patients with SAP were divided into HTG group (n = 45) and control group (n = 131) according to admission triglyceride (TG) 5.65 mmol/L and < 5.65 mmol/L, respectively. Demographics, etiology, underlying diseases, biochemical parameters, Ranson' s score, acute physiology and chronic heath evaluation (APACHE ) score, Balthazar's computed tomography (CT) score, complications and mortality were compared. Correlation between admission TG and 24-h APACHE score was analyzed. RESULTS: SAP patients with HTG were younger (40.8 ± 9.3 years vs 52.6 ± 13.4 years, P < 0.05) with higher etiology rate of overeating, high-fat diet (40.0% vs 14.5%, P < 0.05) and alcohol abuse (46.7% vs 23.7%, P < 0.01), incidence rate of hypocalcemia (86.7% vs 63.4%, P < 0.01) and hypoalbuminemia (84.4% vs 60.3%, P < 0.01), 24-h APACHE score (13.6 ± 5.7 vs 10.7 ± 4.6, P < 0.01) and admission serum glucose (17.7 ± 7.7 vs 13.4 ± 6.1, P < 0.01), complication rate of renal failure (51.1% vs 16.8%, P < 0.01), shock (37.9% vs 14.5%, P < 0.01) and infection (37.4% vs 18.3%, P < 0.01) and mortality (13.1% vs 9.1%, P < 0.01). Logistic regression analysis showed a positive correlation between admission TG and 24-h APACHE score (r = 0 .509, P = 0.004).CONCLUSION: The clinical features of SAP patients with HTG are largely consistent with previous studies. HTG aggravates the episodes of SAP. | Li-Hui Deng Ping Xue Qing Xia Xiao-Nan Yang Mei-Hua Wan | 2008 | World Journal of Gastroenterology2008，14，28： | 59 |

| 5 | Liver transplantation for hepatocellular carcinoma beyond the Milan criteria: A review显示文摘Liver transplantation(LT) has been accepted as an effective therapy for hepatocellular carcinoma(HCC). The Milan criteria(MC) are widely used across the world to select LT candidates in HCC patients. However, the MC may be too strict because a substantial subset of patients who have HCC exceed the MC and who would benefit from LT may be unnecessarily excluded from the waiting list. In recent years, many extended criteria beyond the MC were raised, which were proved to be able to yield similar outcomes compared with those patients meeting the MC. Because the simple use of tumor size and number was insufficient to indicate HCC biological features and to predict the risk of tumor recurrence, some biological markers such as Alphafetoprotein, Des-Gamma-carboxy prothrombin and the neutrophil-to-lymphocyte ratio were useful in selecting LT candidates in HCC patients beyond the MC. For patients with advanced HCC, downstaging therapy is an effective way to reduce the tumor stage to fulfill the MC by using liver-directed therapy such as transarterial chemoembolization, radiofrequency ablation and percutaneous ethanol injection. This article reviews the recent advances in LT for HCC beyond the MC. | Dong-Wei Xu Ping Wan Qiang Xia | 2016 | World Journal of Gastroenterology2016，22，12： | 31 |
| 6 | Advances in treatment of ulcerative colitis with herbs: From bench to bedside显示文摘Ulcerative colitis(UC), an idiopathic inflammatory disorder in the colon, has become a clinical challenge, owing to the increasing incidence and poor prognosis. The conventional treatments for UC including aminosalicylates, corticosteroids, and immunosuppressants, induce remission in only half of patients. Meanwhile, the treatments often come with serious side effects which can be life-threatening. Herbal medicine, one of the most common traditional Chinese medicine modalities, has been introduced for centuries into clinical treatment of many human diseases such as infections and functional disorders. Recently, the potential effectiveness of herbs has been suggested as the treatment of UC, as shown by a variety of clinical trials and experimental studies. The herbs reported in the literature include aloe vera gel, butyrate, tormentil extracts, wheat grass juice, and curcumin. In the review, bioactivity of the herbs and their involvement in UC treatment are discussed. | Ping Wan Hao Chen Yuan Guo Ai-Ping Bai | 2014 | World Journal of Gastroenterology2014，20，39： | 21 |
| 7 | Effect of Chaiqinchengqi decoction on sarco/endoplasmic reticulum Ca^(2+)-ATPase mRNA expression of pancreatic tissues in acute pancreatitis rats显示文摘AIM: To investigate the effect of Chaiqinchengqi decoction (CQCQD) on sarco/endoplasmic reticulum Ca2+-ATPase (SERCA) mRNA expression of pancreatic tissues in acute pancreatitis (AP) rats. METHODS: Thirty Sprague-Dawley (SD) rats were randomized into control group, AP group and CQCQD group (n = 3 × 10). The rats in the CQCQD group were intragastrically administered with CQCQD (10 mL/kg every 2 h) after induction of AP by intraperitoneal injection of caerulein (50 μg/kg.h × 5) within 4 h. At 6 h after the induction of AP model, pancreatic tissues were collected for the pathological observation, mRNA extraction for determination of SERCA1 and SERCA2 mRNA expression or pancreatic acinar cell isolation for measurement of fluorescence intensity (FI) of intracellular calcium ion concentration [Ca2+]i. RESULTS: There was no expression of pancreatic SERCA1 mRNA in the control group and the AP group. The expression of pancreatic SERCA2 mRNA in the AP group was down-regulated (expression ratio = 0.536; P = 0.001) compared with the control group, while that in the CQCQD group was up-regulated (expression ratio= 2.00; P = 0.012) compared with AP group. The FI of intracellular [Ca2+] of pancreatic acinar cells in the AP group (138.2 ± 23.1) was higher than the C group (111.0 ± 18.4) and the CQCQD group (118.7 ± 15.2 ) (P < 0.05) and the pancreatic pathological score in the CQCQD group was lower than that in the AP group (5.7 ± 1.9 vs 9.2 ± 2.7, P < 0.05).CONCLUSION: CQCQD can up-regulate the expression of SERCA2 mRNA of pancreatic tissues, reduce intracellular calcium overload and relieve pancreatic tissue lesions. | Ping Xue Li-Hui Deng Zhao-Da Zhang Xiao-Nan Yang Qing Xia Da-Kai Xiang Lei Huang Mei-Hua Wan | 2008 | World Journal of Gastroenterology2008，14，15： | 20 |

| 9 | Allyl isothiocyanate ameliorates lipid accumulation and inflammation in nonalcoholic fatty liver disease via the Sirt1/AMPK and NF-κB signaling pathways显示文摘BACKGROUND Allyl isothiocyanate(AITC),a classic anti-inflammatory and antitumorigenic agent,was recently identified as a potential treatment for obesity and insulin resistance.However,little is known about its direct impact on the liver.AIM To investigate the effect and underlying mechanism of AITC in nonalcoholic fatty liver disease(commonly referred to as NAFLD).METHODS To establish a mouse and cellular model of NAFLD,C57BL/6 mice were fed a high fat diet(HFD)for 8 wk,and AML-12 cells were treated with 200μM palmitate acid for 24 h.For AITC treatment,mice were administered AITC(100 mg/kg/d)orally and AML-12 cells were treated with AITC(20μmol/L).RESULTS AITC significantly ameliorated HFD-induced weight gain,hepatic lipid accumulation and inflammation in vivo.Furthermore,serum alanine aminotransferase and aspartate aminotransferase levels were markedly reduced in AITC-treated mice.Mechanistically,AITC significantly downregulated the protein levels of sterol regulatory elementbinding protein 1(SREBP1)and its lipogenesis target genes and upregulated the levels of proteins involved in fatty acidβ-oxidation,as well as the upstream mediators Sirtuin 1(Sirt1)and AMPactivated protein kinaseα(AMPKα),in the livers of HFD-fed mice.AITC also attenuated the nuclear factor kappa B(NF-κB)signaling pathway.Consistently,AITC relieved palmitate acid-induced lipid accumulation and inflammation in AML-12 cells in vitro through the Sirt1/AMPK and NF-κB signaling pathways.Importantly,further studies showed that the curative effect of AITC on lipid accumulation was abolished by siRNA-mediated knockdown of either Sirt1 or AMPKαin AML-12 cells.CONCLUSION AITC significantly ameliorates hepatic steatosis and inflammation by activating the Sirt1/AMPK pathway and inhibiting the NF-κB pathway.Therefore,AITC is a potential therapeutic agent for NAFLD. | Chun-Xiao Li Jian-Guo Gao Xing-Yong Wan Yi Chen Cheng-Fu Xu Ze-Min Feng Hang Zeng Yi-Ming Lin Han Ma Ping Xu Chao-Hui Yu You-Ming Li | 2019 | World Journal of Gastroenterology2019，25，34： | 14 |
| 10 | The Predictive Value of Baseline HBs Ag Level and Early Response for HBs Ag Loss in Patients with HBe Ag-positive Chronic Hepatitis B during Pegylated Interferon Alpha-2a Treatment显示文摘Objective To explore the predictive value of baseline HBsAg level and early response for HBsAg loss in patients with HBeAg-positive chronic hepatitis B during pegylated interferon alpha-2a treatment. Methods A total of 121 patients with HBeAg-positive chronic hepatitis B who achieved HBsAg loss were enrolled; all patients were treated with PEG-IFNα-2a 180 μg/week. Serum HBV DNA and serological indicators(HBsAg, anti-HBs, HBeAg, and anti-HBe) were determined before and every 3 months during treatment. Results The median treatment time for HBsAg loss was 84 weeks(7-273 weeks), and 74.38%(90 cases) of the patients needed extended treatment(> 48 weeks). The correlation between baseline HBsAg levels and the treatment time of HBsAg loss was significant(B = 14.465, t = 2.342, P = 0.021). Baseline HBsAg levels together with the decline range of HBsAg at 24 weeks significantly correlated with the treatment time of HBsAg loss(B = 29.862, t = 4.890, P = 0.000 and B = 27.993, t = 27.993, P = 0.005). Conclusion Baseline HBsAg levels and extended therapy are critical steps toward HBsAg loss. Baseline HBsAg levels together with early response determined the treatment time of HBsAg loss in patients with HBeAg-positive chronic hepatitis B during pegylated interferon alpha-2a treatment. | LI Ming Hui ZHANG Lu QU Xiao Jing LU Yao SHEN Ge LI Zhen Zhen WU Shu Ling LIU Ru Yu CHANG Min HU Lei Ping HUA Wen Hao SONG Shu Jing WAN Gang XIE Yao | 2017 | Biomedical and Environmental Sciences2017，30，3： | 14 |

| 13 | Alginate oligosaccharide-induced intestinal morphology, barrier function and epithelium apoptosis modifications have beneficial effects on the growth performance of weaned pigs显示文摘Background: Alginate oligosaccharide(AOS), produced from alginate by alginate lyase-mediated depolymerisation, is a potential substitute for antibiotics and possesses growth-enhancing effects. Nevertheless, the mechanisms by which AOS regulates porcine growth remain to be elucidated. Therefore, we investigated the AOS-mediated changes in the growth performance of weaned pigs by determining the intestinal morphology, barrier function,as well as epithelium apoptosis.Methods: Twenty-four weaned pigs were distributed into two groups(n = 12) and received either a basal diet(control group) or the same diet supplemented with 100 mg/kg AOS. On d 15, D-xylose(0.1 g/kg body weight)was orally administrated to eight randomly selected pigs per treatment, and their serum and intestinal mucosa samples were collected 1 h later.Results: Our results showed that inclusion of AOS in the diet for 2 wk increased(P < 0.05) the average daily body weight gain in weaned pigs. Notably, AOS supplementation ameliorated the intestinal morphology and barrier function, as suggested by the enhanced(P < 0.05) intestinal villus height, secretory immunoglobulin A content and goblet cell counts. Compared to the control group, AOS ingestion both decreased(P < 0.05) the total apoptotic percentage and increased(P < 0.05) the proportion of S phase in the intestinal epithelial cells. Furthermore, AOS not only up-regulated(P < 0.05) the B-cell lymphoma-2(BCL2) transcriptional level but also down-regulated(P < 0.05) the B-cell lymphoma-2-associated X protein(BAX), cysteinyl aspartate-specific proteinase-3(caspase-3) and caspase-9 transcriptional levels in the small intestine.Conclusions: In summary, this study provides evidence that supplemental AOS beneficially affects the growth performance of weaned pigs, which may result from the improved intestinal morphology and barrier function,as well as the inhibited enterocyte death, through reducing apoptosis via mitochondria-dependent apoptosis. | Jin Wan Jiao Zhang Daiwen Chen Bing Yu Xiangbing Mao Ping Zheng Jie Yu Junqiu Luo Jun He | 2018 | Journal of Animal Science and Biotechnology2018，9，4： | 10 |

| 16 | Diffraction-limited imaging with monolayer 2D material-based ultrathin flat lenses显示文摘Ultrathin flat optics allow control of light at the subwavelength scale that is unmatched by traditional refractive optics.To approach the atomically thin limit,the use of 2D materials is an attractive possibility due to their high refractive indices.However,achievement of diffraction-limited focusing and imaging is challenged by their thickness-limited spatial resolution and focusing efficiency.Here we report a universal method to transform 2D monolayers into ultrathin flat lenses.Femtosecond laser direct writing was applied to generate local scattering media inside a monolayer,which overcomes the longstanding challenge of obtaining sufficient phase or amplitude modulation in atomically thin 2D materials.We achieved highly efficient 3D focusing with subwavelength resolution and diffractionlimited imaging.The high focusing performance even allows diffraction-limited imaging at different focal positions with varying magnifications.Our work paves the way for downscaling of optical devices using 2D materials and reports an unprecedented approach for fabricating ultrathin imaging devices. | Han Lin Zai-Quan Xu Guiyuan Cao Yupeng Zhang Jiadong Zhou Ziyu Wang Zhichen Wan Zheng Liu Kian Ping Loh Cheng-Wei Qiu Qiaoliang Bao Baohua Jia | 2020 | Light(Science & Applications)2020，9，1： | 9 |

| 18 | CD147-spike protein is a novel route for SARS-CoV-2 infection to host cells显示文摘In face of the everlasting battle toward COVID-19 and the rapid evolution of SARS-CoV-2,no specific and effective drugs for treating this disease have been reported until today.Angiotensin-converting enzyme 2(ACE2),a receptor of SARS-CoV-2,mediates the virus infection by binding to spike protein.Although ACE2 is expressed in the lung,kidney,and intestine,its expressing levels are rather low,especially in the lung.Considering the great infectivity of COVID-19,we speculate that SARS-CoV-2 may depend on other routes to facilitate its infection.Here,we first discover an interaction between host cell receptor CD147 and SARS-CoV-2 spike protein.The loss of CD147 or blocking CD147 in Vero E6 and BEAS-2B cell lines by anti-CD147 antibody,Meplazumab,inhibits SARSCoV-2 amplification.Expression of human CD147 allows virus entry into non-susceptible BHK-21 cells,which can be neutralized by CD147 extracellular fragment.Viral loads are detectable in the lungs of human CD147(hCD147)mice infected with SARS-CoV-2,but not in those of virus-infected wild type mice.Interestingly,virions are observed in lymphocytes of lung tissue from a COVID-19 patient.Human T cells with a property of ACE2 natural deficiency can be infected with SARS-CoV-2 pseudovirus in a dosedependent manner,which is specifically inhibited by Meplazumab.Furthermore,CD147 mediates virus entering host cells by endocytosis.Together,our study reveals a novel virus entry route,CD147-spike protein,which provides an important target for developing specific and effective drug against COVID-19. | Ke Wang Wei Chen Zheng Zhang Yongqiang Deng Jian-Qi Lian Peng Du Ding Wei Yang Zhang Xiu-Xuan Sun Li Gong Xu Yang Lei He Lei Zhang Zhiwei Yang Jie-Jie Geng Ruo Chen Hai Zhang Bin Wang Yu-Meng Zhu Gang Nan Jian-Li Jiang Ling Li Jiao Wu Peng Lin Wan Huang Liangzhi Xie Zhao-Hui Zheng Kui Zhang Jin-Lin Miao Hong-Yong Cui Min Huang Jun Zhang Ling Fu Xiang-Min Yang Zhongpeng Zhao Shihui Sun Hongjing Gu Zhe Wang Chun-Fu Wang Yacheng Lu Ying-Ying Liu Qing-Yi Wang Huijie Bian Ping Zhu Zhi-Nan Chen | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 9 |
| 19 | Glass-forming ability and corrosion performance of Mn-doped Mg-Zn-Ca amorphous alloys for biomedical applications显示文摘In the present work, ribbon and 2-mm rod samples of Mg-Zn-Ca-Mn alloys were prepared by meltspinning and copper mold injection methods, respectively.Effects of Mn doping on glass-forming ability and corrosion performance in simulated body fluid of Mg_(65)Zn_(30)Ca_5 alloy were studied through X-ray diffraction, scanning electron microscopy, differential scanning calorimeter, and electrochemical and immersion tests. Results show that with the Mn addition increasing, all the ribbon samples are completely in amorphous state. However, the microstructure of 2-mm rod samples transfers from fully amorphous for the Mn-free alloy to almost polycrystalline state with precipitated Mg, Mn, and MgZn phases. Glass-forming ability of Mg_(65)Zn_(30)Ca_5 alloy is decreased by Mn addition.Results of electrochemical and immersion tests demonstrate that the Mn-doped samples exhibit more negative corrosion potential and larger corrosion current density,suggesting that the corrosion resistance decreases with doping amount of Mn element increasing. | Jian-Li Wang Yin Wan Zhi-Jun Ma Yong-Chun Guo Zhong Yang Ping Wang Jian-Ping Li | 2018 | Rare Metals2018，37，7： | 8 |
| 20 | MicroRNA-155 promotes the pathogenesis of experimental colitis by repressing SHIP-1 expression显示文摘AIM To explore the mechanism by which micro RNA-155(miR-155) regulates the pathogenesis of experimental colitis.METHODS A luciferase assay was performed to confirm the binding of miR-155 to the SHIP-1 3'-UTR. MiR-155 mimics, negative controls and SHIP-1 expression/knockdown vectors were established and then utilized in gain-and loss-of-function studies performed in raw264.7 cells and primary bone marrow-derived macrophages (BMDMs). Thereafter, dextran sulfate sodium(DSS)-induced colitis mouse model with or without antagomiR-155 treatment was established, and the levels of miR-155 and SHIP-1, as well as the pro-inflammatory capabilities, were measured by western blot, quantitative polymerase chain reaction, and immunohistochemistry.RESULTS MiR-155 directly bound to the 3'-UTR of SHIP-1 mRNA and induced a significant decrease in SHIP-1 expression in both raw264.7 cells and primary BMDMs. MiR-155 markedly promoted cell proliferation and proinflammatory secretions including IL-6, TNF-α, IL-1β, and IFN-γ, whereas these effects could be reversed by the restoration of SHIP-1 expression. In vivo studies showed that antagomiR-155 administration could alleviate DSS-induced intestinal inflammation in Balb/c mice. Moreover, significantly increased SHIP-1 expression, as well as decreased Akt activation and inflammatory response, were observed in the antagomiR-155-treated mice.CONCLUSION MiR-155 promotes experimental colitis by repressing SHIP-1 expression. Thus, the inhibition of miR-155 might be a promising strategy for therapy. | Zhan-Jun Lu Jian-Jiong Wu Wei-Liang Jiang Jun-Hua Xiao Kai-Zhong Tao Lei Ma Ping Zheng Rong Wan Xing-Peng Wang | 2017 | World Journal of Gastroenterology2017，23，6： | 8 |
