1Adjuvant probiotics improve the eradication effect of triple therapy for Helicobacter pylori infection显示文摘AIM:To investigate whether the addition of probiotics can improve the eradication effect of triple therapy for Helicobacter pylori (H. pylori ) infection. METHODS:This open randomized trial recruited 234 H. pylori positive gastritis patients from seven local centers. The patients were randomized to one-week standard triple therapy (omeprazole 20 mg bid , clarithromycin 500 mg bid , and amoxicillin 1000 mg bid ; OCA group, n = 79); two weeks of pre-treatment with probiotics, containing 3 × 107 Lactobacillus acidophilus per day, prior to one week of triple therapy (POCA group, n = 78); or one week of triple therapy followed by two weeks of the same probiotics (OCAP group, n = 77). Successful eradication was defined as a negative C13 or C14 urease breath test four weeks after triple therapy. Patients were asked to report associated symptoms at baseline and during follow-up, and side effects related to therapy were recorded. Data were analyzed by both intention-to-treat (ITT) and per-protocol (PP) methods. RESULTS:PP analysis involved 228 patients, 78 in the OCA, 76 in the POCA and 74 in the OCAP group. Successful eradication was observed in 171 patients; by PP analysis, the eradication rates were significantly higher (P = 0.007 each) in the POCA (62/76; 81.6%, 95% CI 72.8%-90.4%) and OCAP (61/74; 82.4%, 95% CI 73.6%-91.2%) groups than in the OCA group (48/78; 61.5%, 95% CI 50.6%-72.4%). ITT analysis also showed that eradication rates were significantly higher in the POCA (62/78; 79.5%, 95% CI 70.4%-88.6%) and OCAP (61/77; 79.2%, 95% CI 70%-88.4%) groups than in the OCA group (48/79; 60.8%, 95% CI 49.9%-71.7%), (P = 0.014 and P = 0.015). The symptom relieving rates in the POCA, OCAP and OCA groups were 85.5%, 89.2% and 87.2%, respectively. Only one of the 228 patients experienced an adverse reaction. CONCLUSION:Administration of probiotics before or after standard triple therapy may improve H. pylori eradication rates.Yi-Qi Du Tun Su Jian-Gao Fan Yu-Xia Lu Ping Zheng Xing-Hua Li Chuan-Yong Guo Ping Xu Yan-Fang Gong Zhao-Shen Li 2012World Journal of Gastroenterology2012,18,43:54

3Controlled attenuation parameter for non-invasive assessment of hepatic steatosis in Chinese patients显示文摘AIM:To evaluate the performance of a novel non-invasive controlled attenuation parameter(CAP)to assess liver steatosis.METHODS:This was a multi-center prospective cohort study.Consecutive patients(aged≥18 years)who had undergone percutaneous liver biopsy and CAP measurement were recruited from three Chinese liver centers.Steatosis was categorized as S0:<5%;S1:5%-33%;S2:34%-66%;or S3:≥67%,according to the nonalcoholic fatty liver disease(NAFLD)activity score.The FibroScan?502 equipped with the M probe(Echosens,Paris,France)was used to capture both CAP and liver stiffness measurement values simultaneously.Receiver operating characteristic curves were plotted,and the areas under the curves were calculated to determine the diagnostic efficacy.The accuracy of the CAP values at the optimal thresholds was defined by maximizing the sum of sensitivity and specificity(maximum Youden index).RESULTS:A total of 152 patients were recruited,including 52(34.2%)patients with NAFLD and 100(65.8%)with chronic hepatitis B(CHB)virus infection.After adjustment,the steatosis grade(OR=37.12;95%CI:21.63-52.60,P<0.001)and body mass index(BMI,OR=6.20;95%CI:2.92-9.48,P<0.001)were found independently associated with CAP by multivariate linear regression analysis.CAP was not influenced by inflammation,fibrosis or aetiology.The median CAP values and interquartile ranges among patients with S0,S1,S2 and S3 steatosis were 211(181-240)dB/m,270(253-305)dB/m,330(302-360)dB/m,and 346(313-363)dB/m,respectively.The cut-offs for the CAP values in all patients with steatosis≥5%,≥34%and≥67%were 253 dB/m,285 dB/m and 310 dB/m,respectively.The areas under the curves were 0.92,0.92and 0.88 for steatosis≥5%,≥34%and≥67%,respectively.No significant differences were found in the CAP values between the NAFLD group and the CHB group in each steatosis grade.CONCLUSION:CAP appears to be a promising tool for the non-invasive detection and quantification of hepatic steatosis,but is limited by BMI.Feng Shen Rui-Dan Zheng Yu-Qiang Mi Xiao-Ying Wang Qin Pan Guang-Yu Chen Hai-Xia Cao Ming-Li Chen Liang Xu Jian-Neng Chen Yi Cao Rui-Nan Zhang Lei-Ming Xu Jian-Gao Fan 2014World Journal of Gastroenterology2014,20,16:55
4Roux-en-Y choledochojejunostomy using novel magnetic compressive anastomats in canine model of obstructive jaundice显示文摘BACKGROUND:The traditional hand-sewn Roux-en-Y choledochojejunostomy is technically complicated,and the incidence of postoperative complications has remained high.A set of novel magnetic compressive anastomats was introduced to facilitate choledochojejunostomy and improve the prognosis of patients.METHODS:After ligating the common bile duct for 7 days,16 dogs were randomly divided into two groups (n=8 per group).Anastomats were used in the study group,and the traditional hand-sewn method was used in the control group for standard Roux-en-Y choledochojejunostomy.We compared the operation time,incidence of complications,gross appearance,and pathological disparity in stoma between the two groups in 1-month and 3-month follow-up examinations.RESULTS:The time spent on constructing the anastomosis for the study group was significantly shortened.Although no anastomotic stenosis occurred in the two groups,the narrowing rate of biliary-enteric anastomosis was much higher in the control group.There was one case of bile leakage in the control group,whereas no bile leakage occurred in the study group.A smoother surface,an improved layer apposition,and a lower local inflammatory response were identified in the anastomosis of the study group.CONCLUSION:The structures of the novel magnetic compressive anastomats are simple,and they are time-saving,safe and efficient for performing Roux-en-Y choledocho- jejunostomy procedures in a canine model of obstructive jaundice.Chao Fan,Xiao-Peng Yan,Shi-Qi Liu,Chun-Bao Wang,Jian-Hui Li,Liang Yu,Zheng Wu and Yi Lv Department of Hepatobiliary Surgery and Department of Pathology,First Affiliated Hospital,School of Medicine,Xi’an Jiaotong University,Xi’an 710061,China Department of Surgical Oncology,Third Affiliated Hospital,School of Medicine,Xi’an Jiaotong University,Xi’an 710068,China 2012Hepatobiliary & Pancreatic Diseases International2012,11,1:49
5Correlation of E-selectin gene polymorphisms with risk of ischemic stroke A meta-analysis显示文摘OBJECTIVE: To investigate the association of E-selectin S128R polymorphisms with ischemic stroke. DATA SOURCES: A computer-based online search was conducted in PubMed, Elsevier, Ovid Database, the China National Knowledge Infrastructure, and Wanfang Database between January 1998 and December 2010. STUDY SELECTION: Case-controlled studies addressing the association of the E-selectin polymorphism and ischemic stroke were included in this review. The genotype distribution complied with the Hardy-Weinberg genetic equilibrium. The included reports were evaluated by two authors for strict quality screening. Meta-analysis software, REVMAN 5.1, was used to investigate heterogeneity, pooled odds ratio (OR) and 95% confidence interval (CI) in individual studies. MAIN OUTCOME MEASURES: Genotype and allele distributions at the E-selectin S128R site. RESULTS: Six case-controlled studies were included after screening and application of inclusion and exclusion criteria. There was no heterogeneity in the genotype and allele frequencies, and no publication bias was found. Meta-analysis of the pooled data showed that the OR value of the (AC+CC)/AA genotype was 1.93 (95% CI: 1.55-2.41, Z = 5.80, P < 0.000 01), and the OR for the C/A allele was 1.80 (95% CI: 1.47-2.22, Z = 5.59, P < 0.000 01) in the ischemic stroke group, compared with control group. Results of pooled data in Chinese subjects showed that the OR value of (AC+CC)/AA was 2.36 (95% CI: 1.68-3.31, Z = 4.99, P < 0.000 01), and the OR value of the C/A allele was 2.25 (95% CI: 1.63-3.12, Z = 4.89, P < 0.000 01). CONCLUSION: Polymorphism of E-selectin S128R was significantly associated with susceptibility to ischemic stroke; the AC and CC genotypes as well as the C allele may be factors associated with susceptibility to ischemic stroke.Qingli Sun Yu Fu Aping Sun Yanhong Shou Mei Zheng Xiaogang Li Dongsheng Fan 2011Neural Regeneration Research2011,6,22:46

10Clinical efficacy of tolvaptan for treatment of refractory ascites in liver cirrhosis patients显示文摘AIM: To evaluate the efficacy and safety of tolvaptan to treat refractory ascites in decompensated liver cirrhosis patients with or without further complications, such as hepatorenal syndrome and/or hepatocellular carcinoma.METHODS: Thirty-nine patients(mean age 55 years, males: 32) with decompensated liver cirrhosis and refractory ascites were enrolled. All patients received a combination of tolvaptan(15 mg/d for 5-14 d) and diuretics(40-80 mg/d of furosemide and 80-160 mg/d of spironolactone). The etiology of cirrhosis included hepatitis B(69.2%), hepatitis C(7.7%) and alcohol-in-duced(23.1%). Changes in the urine excretion volume, abdominal circumference and edema were assessed. The serum sodium levels were also measured, and adverse events were recorded. A follow-up assessment was conducted 1 mo after treatment with tolvaptan.RESULTS: Tolvaptan increased the mean urine excretion volume(1969.2 ± 355.55 mL vs 3410.3 ± 974.1 mL, P < 0.001), and 89.7% of patients showed improvements in their ascites, 46.2% of whom showed significant improvements. The overall efficacy of tolvaptan in all patients was 89.7%; the efficacies in patients with hepatocellular carcinoma and hepatorenal syndrome were 84.2% and 77.8%, respectively. The incidence of hyponatremia was 53.8%. In patients with hyponatremia, the serum sodium levels increased after tolvaptan treatment(from 128.1 ± 4.22 mEq/L vs 133.1 ± 3.8 mEq/L, P < 0.001). Only mild drug-related adverse events, including thirst and dry mouth, were observed. CONCLUSION: Tolvaptan is a promising aquaretic for the treatment of refractory ascites in patients with decompensated liver cirrhosis.Xin Zhang Shu-Zhen Wang Jun-Fu Zheng Wen-Min Zhao Peng Li Chun-Lei Fan Bing Li Pei-Ling Dong Lei Li Hui-Guo Ding 2014World Journal of Gastroenterology2014,20,32:36
11Caspase-11/4 and gasdermin D-mediated pyroptosis contributes to podocyte injury in mouse diabetic nephropathy显示文摘Diabetic nephropathy(DN)is characterized by sterile inflammation with continuous injury and loss of renal inherent parenchyma cells.Podocyte is an essential early injury target in DN.The injury and loss of podocytes are closely associated with proteinuria,the early symptom of renal injury in DN.However,the exact mechanism for podocyte injury and death in DN remains ambiguous.In this study we investigated whether pyroptosis,a newly discovered cell death pathway was involved in DN.Diabetic mice were generated by high-fat diet/STZ injections.We showed that the expression levels of caspase-11 and cleavage of gasdermin D(GSDMD-N)in podocytes were significantly elevated,accompanied by reduced expression of podocyte makers nephrin and podocin,loss and fusion in podocyte foot processes,increased inflammatory cytokines NF-κB,IL-1β,and IL-18,macrophage infiltration,glomerular matrix expansion and increased urinary albumin to creatinine ratio(UACR).All these changes in diabetic mice were blunted by knockout of caspase-11 or GSDMD.Cultured human and mouse podocytes were treated with high glucose(30 mM),which significantly increased the expression levels of caspase-11 or caspase-4(the homolog of caspase-11 in human),GSDMD-N,NF-κB,IL-1β,and IL-18,and decreased the expression of nephrin and podocin.Either caspase-4 or GSDMD knockdown by siRNA significantly blunted these changes.In summary,our results demonstrate that caspase-11/4 and GSDMD-mediated pyroptosis is activated and involved in podocyte loss under hyperglycemia condition and the development of DN.Qian Cheng Jing Pan Zhuan-li Zhou Fan Yin Hong-yan Xie Pan-pan Chen Jing-yao Li Pei-qing Zheng Li Zhou Wei Zhang Jun Liu Li-min Lu 2021Acta Pharmacologica Sinica2021,42,6:33
12Sorafenib in treatment of patients with advanced hepatocellular carcinoma:a systematic review显示文摘BACKGROUND: Sorafenib has become the standard first-line treatment for patients with advanced hepatocellular carcinoma (HCC). This study aimed to assess the efficacy and safety of sorafenib in advanced HCC patients and explore its true value for specific subgroups. DATA SOURCES: A computer-based systematic search from January 2005 to June 2011 with 'sorafenib' and 'advanced hepatocellular carcinoma' as search terms was performed for possible clinical trials. Hazard ratios (HR) and their 95% confidence intervals (CI) for overall survival (OS) and time to progression (TTP), rates of partial response (PR), rates of toxicity effects, and details of subgroup analysis were extracted. Meta-analyses were done using the software Review Manager (version 5.0). RESULTS: Six trials with 1164 patients were included. Based on three randomized controlled trials, the pooled HR (sorafenib/ placebo) was 0.66 for OS (95% CI: 0.56-0.78; P<0.00001) and 0.57 for TTP (95% CI: 0.47-0.68; P<0.00001). The pooled odds ratio (OR) for PR was 2.96 (95% CI: 0.96-9.15; P=0.06). For three single-arm trials, the pooled HR was 0.69 for OS (95% CI: 0.56-0.84; P=0.0002) and 0.64 for TTP (95% CI: 0.52-0.78; P<0.00001). The pooled OR for PR in three single-arm trials was 3.56 (95% CI: 1.22-10.39; P=0.02). Subgroup analysis indicated that sorafenib was less effective in patients with extrahepatic spread (with: P=0.13 vs without: P<0.0001), with normal alpha-fetoprotein level (AFP) (P=0.15 vs elevated: P=0.0006), and with elevated level of serum bilirubin (P=0.06 vs normal: P=0.0009). Sorafenib-based therapy significantly increased the risk of grade 3/4 hand-foot skin reaction, diarrhea, fatigue, and rash/desquamation.CONCLUSIONS: Sorafenib-based therapy benefits advanced HCC patients. Meanwhile, sorafenib is less effective for patients with extrahepatic spread, with normal AFP level and with elevated level of bilirubin.Xin Zhang, Xin-Rong Yang, Xiao-Wu Huang, Wei-Min Wang, Ruo-Yu Shi, Yang Xu, Zheng Wang, Shuang-Jian Qiu, Jia Fan ,Jian Zhou Liver Cancer Institute, Zhongshan Hospital, Fudan University, Shanghai Key Laboratory for Organ Transplantation, Shanghai 200032, China,Institute of Biomedical Sciences, Fudan University, Shanghai 200032, China 2012Hepatobiliary & Pancreatic Diseases International2012,11,5:29
13Orbit determination of Chang'E-3 and positioning of the lander and the rover显示文摘Chang’E-3 landed on the east of Sinus Iridum area on December 14,2013,performing China’s first successful soft landing on the lunar surface.We present the results on precision orbit determination and positioning of the lander and the rover.We describe the data,modeling,and methods used to achieve position knowledge over the period December 2–21,2014.In addition to the radiometric X-band range and Doppler tracking data,delta differential one-way ranging data are also used in the calculation,which show that they strongly improve the accuracy of the orbit reconstruction.Total position overlap differences are about 20 and 30 m for the 100 km 9 100 km and100 km9 15 km lunar orbit,respectively,increased by*50%with respect to CE-2 and at the same level as other lunar spacecrafts of recent era such as SELENE and lunar reconnaissance orbiter(LRO).The position error of the soft landing trajectory is less than 100 m.A kinematic statistical method is applied to determine the position of the lander and relative position of the rover with respect to the lander.The position difference of the lander is better than50 m compared to LRO photograph result.Compared with the delta very long baseline interferometry(VLBI)group delay between the lander and the rover,the delta VLBI phase delay can improve the relative position of the rover from*1,000 to*1 m.Yong Huang Shengqi Chang Peijia Li Xiaogong Hu Guangli Wang Qinghui Liu Weimin Zheng Min Fan 2014Chinese Science Bulletin2014,59,29:28
14Expression and function of classical protein kinase C isoenzymes in gastric cancer cell line and its drugresistant sublines显示文摘AIM: To investigate the expression and function of classicalprotein kinase C (PKC) isoenzymes in inducing MDRphenotype in gastric cancer cells.METHODS: Two cell lines were used in the study: gastriccancer cell SGC7901 and its drug-resistant cell SGC7901/VCRstepwise-selected by vincristine 0.3, 0. 7 and 1.0 mg@ L-1 ,respectively. The expression of classical PKC (cPKC)isoenzymes in SGC7901 cells and SGC7901/VCR cells weredetected using immunofluorescent cytochemistry, laserconfocal scanning microscope and Wsstern blot. The effectsof anti-PKC isoenzymes antibody of adriamycinaccumulation in SGC7901/VCR cells were determined usingflow cytometric analysis.RESULTS: (1) SGC7901 cells exhibited positive staining ofPKC-α. SGC7901/VCR cells exhibited stronger staining ofPKC-α than SGC7901 cells. The higher dosage vincristineselected, the much stronger staining of PKC-α was observedon SGC7901/VCR cells. (2) Both SGC7901 and SGC7901/VCRcells exhibited positive staining of PKC-βⅠ and PKC-βⅡ withno significant difference. ( 3 ) Compared with SGC7901,SGC7901/VCR cells had decreased adriamycin accumulationand retention. Accumulation of adriamycin in SGC7901 was5.21 + 2.56 mg@ L-1, in SGC7901/VCR 0.3 was 0.85 + 0.29 mg@L-1 , in SGC7901/VCR 0.7 was 0.81 + 0.32 og@ L-1 , and inSGC7901NCR 1.0 was 0.80 + 0.33 mg @ L-1; Retention ofadriamycin in SGC 7901 was 2.51 + 1.23 mg@L-1, in SGC7901/VCR 0.3 was 0.47 + 0.14 mg@ L-1 , in SGC7901/VCR 0.7 was 0.44 + 0.15 mg@ L-1, and in SGC 7901/VCR 1.0 was 0.41 + 0.1 1mg @ L-1 . (4) Fluorescence intensity presented adriamycinaccumulation in SGC7901/VCR cells was increased from 1.14+0.36 to 2.71 +0.94 when cells were co-incubated with anti-PKC-αbut not with anti-PKC-βⅠ, PKC-βⅡ and PKCγ antibodies.CONCLUSION: PKC-α, but not PKC-βⅠ, PKC-βⅡ or PKCγ,may play a role in multidrug resistance of gastric cancercells SGC7901/VCR.Ying Han Zhe-Yi Han Xin-Min Zhou Ru Shi Yue Zheng Yong-Quan Shi Ji-Yan Miao Bo-Rong Pan Dai-Ming Fan 2002World Journal of Gastroenterology2002,8,3:25

16International consensus statement on robotic hepatectomy surgery in 2018显示文摘The robotic surgical system has been applied in liver surgery. However,controversies concerns exist regarding a variety of factors including the safety,feasibility, efficacy, and cost-effectiveness of robotic surgery. To promote the development of robotic hepatectomy, this study aimed to evaluate the current status of robotic hepatectomy and provide sixty experts' consensus and recommendations to promote its development. Based on the World Health Organization Handbook for Guideline Development, a Consensus Steering Group and a Consensus Development Group were established to determine the topics, prepare evidence-based documents, and generate recommendations. The GRADE Grid method and Delphi vote were used to formulate the recommendations. A total of 22 topics were prepared analyzed and widely discussed during the 4 meetings. Based on the published articles and expert panel opinion, 7 recommendations were generated by the GRADE method using an evidence-based method, which focused on the safety, feasibility, indication,techniques and cost-effectiveness of hepatectomy. Given that the current evidences were low to very low as evaluated by the GRADE method, further randomized-controlled trials are needed in the future to validate these recommendations.Rong Liu Go Wakabayashi Hong-Jin Kim Gi-Hong Choi Anusak Yiengpruksawan Yuman Fong Jin He Ugo Boggi Roberto I Troisi Mikhail Efanov Daniel Azoulay Fabrizio Panaro Patrick Pessaux Xiao-Ying Wang Ji-Ye Zhu Shao-Geng Zhang Chuan-Dong Sun Zheng Wu Kai-Shan Tao Ke-Hu Yang Jia Fan Xiao-Ping Chen 2019World Journal of Gastroenterology2019,25,12:23
17Establishing dynamic thresholds for potato nitrogen status diagnosis with the SPAD chlorophyll meter显示文摘The hand-held soil plant analysis development(SPAD) chlorophyll meter has proved to be a promising tool in evaluating the nitrogen status of the potato and guiding fertilization recommendations. In the process of N evaluation of potato plants and N recommendation, it is critical to establish the threshold SPAD value(SPAD reading), below which nitrogen supplement is required. And taking convenient using into account, the threshold needs to be dynamic throughout the potato growing season so that the users can test their potato plants and make fertilization decision at any growing time of potato. To complete this goal, field experiments with different nitrogen supply levels were conducted in different sites in northern China from 2009 to 2011. The results showed that threshold SPAD values decrease as the growing season progresses for all cultivars and planting sites. By statistical analysis, the threshold regression models were established respectively as: y=-0.003x2-0.0507x+58.213(y, threshold SPAD value; x, days after emergence) for the potato cultivar Kexin 1, and y=-0.003x2+0.017x+52.489(y, threshold SPAD value; x, days after emergence) for the cultivar Shepody, from which, the threshold SPAD value at any day after emergence can be calculated.ZHENG Hong-li LIU Yan-chun QIN Yong-lin CHEN Yang FAN Ming-shou 2015Journal of Integrative Agriculture2015,14,1:21

19Sutureless Intestinal Anastomosis with a Novel Device of Magnetic Compression Anastomosis显示文摘Objective To explore the feasibility and efficiency of a novel magnetic compression anastomats(MCAs) in intestinal anastomosis.Methods A total of 36 male mongrel canines underwent intestinal anastomosis using traditional hand-sewn(n=18) or a novel MCAs(n=18).We compared the anastomosis time,postoperative complications,bursting strength of anastomoses,gross appearance,and pathology between two groups at each time-point of follow-up.Results The mean anastomosis time with MCAs was significantly less than that with hand-sewn(8.50±1.95 vs.31.1±4.32 minutes,P<0.001).The blood stools and intussusceptions occurred in both groups during follow-up period.Only 1 mongrel canine receiving intestinal anastomosis by MCAs experienced anastomotic leakage.The average bursting pressure of anastomoses obtained from mongrel canines undergoing intestinal anastomosis by MCAs was significantly higher than that by traditional hand-sewn at 1 week's follow-up time(P<0.05).Gross appearance of the anastomoses constructed by MCAs was relatively smoother and flatter.Pathological evalution of anastomoses revealed that general inflammation was greater in hand-sewn anastomoses than magnetic anastomosis.Conclusion The magnetic compression anastomat is a safe and effective device of sutureless intestinal anastomosis in canine models.Chao Fan Jia Ma Hong-ke Zhang Rui Gao Jian-hui Li Liang Yu Zheng Wu Yi Lv 2011Chinese Medical Sciences Journal2011,26,3:20
20Plant Prime Editors Enable Precise Gene Editing in Rice Cells显示文摘Genome editing is revolutionizing plant research and crop breeding.Sequence-specific nucleases(SSNs)such as zinc finger nuclease(ZFN)and TAL effector nuclease(TALEN)have been used to create site-specific DNA double-strand breaks and to achieve precise DNA modifications by promoting homology-directed repair(HDR)(Steinert et al.,2016;Voytas,2013).Later,RNA-guided SSNs such as CRISPR-Cas9,Cas12a,Cas12b,and their variants were applied for genome editing in plants(Li et al.,2013;Nekrasov et alM 2013;Tang et al.,2017;Zhong et al.,2019;Ming et al.,2020;Tang et al.,2019).However,HDR relies on simultaneous delivery of SSNs and DNA donors,which has been challenging in plants(Steinert et al.,2016;Zhang et aL,2019).Another challenge for realizing efficient HDR in plants is that DNA repair favors nonhomologous end joining(NHEJ)pathways over HDR in most cell types(Puchta,2005;Qi et al.,2013).Xu Tang Simon Sretenovic Qiurong Ren Xinyu Jia Mengke Li Tingting Fan Desuo Yin Shuyue Xiang Yachong Guo Li Liu Xuelian Zheng Yiping Qi Yong Zhang 2020Molecular Plant2020,13,5:20
