| 1 | Androgen receptor: structure, role in prostate cancer and drug discovery显示文摘Androgens and androgen receptors (AR) play a pivotal role in expression of the male phenotype. Several diseases, such as androgen insensitivity syndrome (AIS) and prostate cancer, are associated with alterations in AR functions. Indeed, androgen blockade by drugs that prevent the production of androgens and/or block the action of the AR inhibits prostate cancer growth. However, resistance to these drugs often occurs after 2-3 years as the patients develop castration-resistant prostate cancer (CRPC). In CRPC, a functional AR remains a key regulator. Early studies focused on the functional domains of the AR and its crucial role in the pathology. The elucidation of the structures of the AR DNA binding domain (DBD) and ligand binding domain (LBD) provides a new framework for understanding the functions of this receptor and leads to the development of rational drug design for the treatment of prostate cancer. An overview of androgen receptor structure and activity, its actions in prostate cancer, and how structural information and high-throughput screening have been or can be used for drug discovery are provided herein. | MH Eileen TAN Jun LI H Eric XU Karsten MELCHER Eu-leong YONG | 2015 | Acta Pharmacologica Sinica2015，36，1： | 39 |
| 2 | Comparison of renal safety of tenofovir and entecavir in patients with chronic hepatitis B: Systematic review with meta-analysis显示文摘BACKGROUND Recently, the American Association for the Study of Liver Disease suggested no preference between tenofovir(TDF) and entecavir(ETV) regarding potential long-term risks of renal complications. Over the years, renal safety has become a critical concern in nucleos(t)ide analog-treated patients due to the long-term use of these drugs. However, existing studies do not show significant differences in renal dysfunction between these two drugs. Further, there is a paucity of studies comparing the long-term renal effects of TDF and ETV.AIM To investigate the effects of TDF and ETV on renal function, we performed systematic review and meta-analysis.METHODS Two investigators independently searched the Cochrane Library, MEDLINE, and Embase databases for randomized controlled trials and nonrandomized studies(NRSs) using the keywords 'CHB', 'Tenofovir', and 'Entecavir', and additional references were obtained from the bibliographies of relevant articles published through December 2017. The quality of each study was assessed using the Newcastle-Ottawa scale and the Grading of Recommendations Assessment,Development and Evaluation criteria. The primary outcome was the change in serum creatinine level in the TDF and ETV groups at baseline, 6 mo, 12 mo and24 mo.RESULTSNine NRSs comprising 2263 participants met the inclusion criteria. Changes in creatinine levels were higher in the TDF group than in the ETV group at 6 mo[mean difference(MD) = 0.03 mg/dL;95%CI: 0.02-0.04;I2 = 0%], 12 mo(MD =0.05 mg/dL;95%CI: 0.02-0.08;I2 = 78%), and 24 mo(MD = 0.07 mg/dL;95%CI:0.01-0.13;I2 = 93%). The change in estimated glomerular filtration rate(eGFR) was significantly higher in the TDF group than in the ETV group at 6 mo[standardized mean difference(SMD),-0.22;95%Cl:-0.36--0.08;I2 = 0%], 12 mo(SMD =-0.24;95%Cl:-0.43--0.05;I2 = 50%), and 24 mo(-0.35;95%Cl:-0.61--0.09;I2= 67%).CONCLUSION TDF statistically significantly increased serum creatinine levels and decreased the eGFR in 6-24 mo compared to ETV, with moderate to low quality of evidence.However, the differences are negligible. | Hyo-Young Lee Hyunwoo Oh Chan-Hyuk Park Yee-Hui Yeo Mindie H Nguyen Dae-Won Jun | 2019 | World Journal of Gastroenterology2019，25，23： | 6 |

| 4 | Features of extrahepatic metastasis after radiofrequency ablation for hepatocellular carcinoma显示文摘BACKGROUND Extrahepatic metastasis(EHM)of hepatocellular carcinoma(HCC)is associated with poor outcomes.However,the clinical features and risk factors of EHM of HCC after radiofrequency ablation(RFA)remain unclear.AIM To elucidate the characteristics and risk factors of EHM after RFA for HCC.METHODS From January 2008 to December 2017,we retrospectively enrolled 661 patients who underwent RFA as first-line treatment for HCC at 2 tertiary hospitals.The inclusion criteria were age≥18 years,a diagnosis of HCC,and treatment-naivety.Abdominal computed tomography(CT)or magnetic resonance imaging(MRI)and alpha-fetoprotein measurements were routinely performed at 1 mo after RFA and followed-up at intervals of 3-6 mo.Univariate analyses were performed using the chi-squared test or Student’s t-test,and univariate and multivariate analyses were performed via logistic regression,as appropriate.RESULTS EHM was diagnosed in 44 patients(6.7%)during a median follow-up period of 1204 days.The 10-year cumulative rate of HCC recurrence and EHM was 92.7%and 33.7%,respectively.Initial recurrence was most often intrahepatic,and the rate of extrahepatic recurrence at initial recurrence was only 1.2%.The median time to the diagnosis of EHM was 2.68 years,and 68.2%of patients developed EHM within 2 years of the first recurrence,regardless of recurrence-free survival and 75.0%of patients developed EHM within 5 years after first recurrence.EHM was mostly diagnosed via abdominal CT/MRI in 33(75.0%)and 38 of 44 patients(86.4%)with EHM had either positive abdominal CT scan results or serum AFP level elevation.In multivariate analysis,recurrence-free survival<2 years,ablation zone/tumor size<2,and alpha-fetoprotein level>400 IU/mL were associated with a high EHM risk.CONCLUSION EHM occurs following multiple intrahepatic recurrences after RFA and combined contrast-enhanced abdominal CT and serum AFP were useful for surveillance.Patients especially with high-risk factors require close follow-up for EHM. | Jae H Yoon Young J Goo Chae-Jun Lim Sung K Choi Sung B Cho Sang S Shin Chung H Jun | 2020 | World Journal of Gastroenterology2020，26，32： | 3 |

| 8 | Pre-treatment role of inosine triphosphate pyrophosphatase polymorphism for predicting anemia in Egyptian hepatitis C virus patients显示文摘AIM: To investigate and clarify, for the first time, the role of inosine triphosphate pyrophosphatase (ITPA ) polymorphism in Egyptian chronic hepatitis C virus (HCV) patients.METHODS:The human genomic DNA of all patients was extracted from peripheral blood cells in order to determine the single nucleotide polymorphism (SNP) of ITPA (rs1127354). SNP genotyping was performed by real time polymerase chain reaction (PCR, ABI TaqMan allelic discrimination kit) for 102 treatment-naive Egyptian patients with chronic HCV. All patients had no evidence of cardiovascular or renal diseases. They received a combination treatment of pegylated interferon α (PEG-IFNα) as a weekly subcutaneous dose plus an oral weight-adjusted dose of ribavirin (RBV). The majority received PEG-IFNα2a (70.6%) while 29.4% received PEG-IFNα2b. The planned duration of treatment was 24-48 wk according to the viral kinetics throughout the course of treatment. Pre-treatment liver biopsy was done for each patient for evaluation of fibrosis stage and liver disease activity. The basal viral load level was detected quantitatively by real time PCR while viral load throughout the treatment course was performed qualitatively by COBAS TaqMan assay. RESULTS: Ninety-three patients (91.2%) had ITPA SNP CC genotype and 9 (8.8%) had non-CC genotype (CA and AA). The percentage of hemoglobin (Hb) decline was higher for CC patients than for non-CC patients, particularly at weeks 4 and 8 (P=0.047 and 0.034, respectively). During the first 12 wk of treatment, CC patients had significantly more Hb decline > 3 g/dL than non-CC patients: 64.5% vs 22.2% at weeks 8 and 12, respectively, (P=0.024 and 0.038). Reduction of the amount of the planned RBV dose was significantly higher for CC patients than non-CC patients during the first 12 wk (18% ± 12.1% vs 8.5% ± 10.2%, P=0.021). The percentage of CC patients with RBV dose reduction was significantly greater than that of non-CC patients (77.4% vs 44.4%, P=0.044). Multivariate analysis identified only the percentage of RBV dose as a predictor for Hb decline. Platelet decline was significantly higher in non-CC patients than CC patients at weeks 12, 24 and 48 (P=0.018, 0.009 and 0.026, respectively). CONCLUSION: Rs1127354 ITPA polymorphism plays a decisive role in protecting against treatment-induced anemia and the need for RBV dose reduction in Egyptian HCV patients. | Walaa H Ahmed Norihiro Furusyo Saad Zaky Abeer Sharaf Eldin Hany Aboalam Eiichi Ogawa Masayuki Murata Jun Hayashi | 2013 | World Journal of Gastroenterology2013，19，9： | 2 |
