We compared the efficacy and safety between once-daily dosing and on-demand use of udenafil for type 2 diabetic patients with erectile dysfunction （ED）. A multi-center, randomized, open-label, parallel-group, 12-week study was conducted. 161 patients who improved with on-demand 200 mg of udenafil according to Sexual Encounter Profile （SEP） diary Question 2 and 3 （Q2 and Q3） were randomized into 200 mg on-demand （n = 80） or 50 mg once-daily （n = 81） dosing groups for 8 weeks. The dosing period was followed by a 4-week treatment-free period. The primary efficacy endpoint was the change of the International Index of Erectile Function （IieF） erectile function domain （EFD） score. The secondary efficacy endpoints included changes to the SEP diary Q2, Q3, IieF Q3, Q4, other domains of IieF, Global Assessment Question, and shift to the normal rate （EFD 〉 26）. Vascular endothelial markers were also assessed. The IieF-EFD score of both groups improved after 8 weeks of treatment （P 〈 0.0001）. There was no statistically significant difference between two groups. Improvement was not maintained after the treatment-free follow-up period. Similar results were observed in the secondary efficacy endpoints. There was also no significant difference in vascular endothelial markers. Daily udenafil was well-tolerated, and there was no significant difference in the adverse drug reactions and adverse events between the two groups. Flushing and headache were the most frequent adverse events. Both regimens improved ED in diabetic patients and were well-tolerated. Further studies are needed to assess the effect of daily udenafil treatment in diabetic patients.

World Journal of Gastroenterology 2013年第22期19卷 3453-3458页

作者： Soung Hoon Cho Sang Woo Kim Won Chul Kim Jae Myung park ie Ryung Yoo Sung Hoon Kim Seong Taek Oh Division of Gastroenterology Department of Internal Medicine Seoul St. Mary's Hospital The Catholic University of Korea Seoul 137-701 South Korea Department of Radiology Seoul St. Mary's Hospital The Catholic University of Korea Seoul 137-701 South Korea Department of Surgery Seoul St. Mary's Hospital The Catholic University of Korea Seoul 137-701 South Korea

AIM: To assess the clinical significance of incidental focal colorectal 18 F-fluorodeoxyglucose ( 18 F-FDG) uptake on 18 F-FDG-positron emission tomography/computed tomography (PET/CT). METHODS: The records of all the cases which had undergone colonoscopy after PET/CT within a two weeks interval were reviewed. Adenomas were considered advanced when they were villous, ≥ 10 mm in size, or had high-grade dysplasia. Colorectal cancers and advanced adenomas are collectively referred to as advanced colorectal neoplasms. Receiver-operating characteristic curve analysis was used to determine thesignificant predictive maximum standardized uptake value (SUVmax) cutoff value for advanced colorectal neoplasms and cancer. RESULTS: Ninety-five colorectal lesions matched the site of incidental focal colorectal 18 F-FDG uptake on PET/CT and 146 did not. Colonoscopy showed advanced colorectal neoplasms corresponding to the site of 18 F-FDG uptake in 49 of the 95 (51.5%) lesions with incidental uptake. Of the lesions without incidental uptake, only 6 of 146 (4.1%) had advanced colorectal neoplasms on colonoscopy, indicating a statistically significant difference between the two groups (P < 0.001). The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of incidental focal 18 F-FDG uptake in identifying advanced colorectal neoplasms were 89.1%, 75.3%, 51.6%, 95.9%, and 78.4%, respectively. In detecting only CRC, these values were 89.2%, 69.6%, 34.7%, 97.3%, and 72.6%, respectively. The significant SUVmax cutoff value for advanced colorectal neoplasms (area under the curve 0.755, P < 0.001) was 4.35, with a sensitivity, specificity, PPV, NPV, and accuracy of 75.5%, 65.2%, 69.8%, 71.4% and 70.5%, respectively. For CRC, 5.05 was the significant SUVmax cutoff value (area under the curve 0.817, P < 0.001), with a sensitivity, specificity, PPV, NPV, and accuracy of 84.8%, 71.0%, 80.9%, 89.8%, and 75.8%, respectively. CONCLUSION: The prese

既有浅埋隧道上方填土可能导致其衬砌变形、安全系数降低,甚至发生破坏,危及行车安全。以长枪岭隧道上方某拟建公园填土工程为例,选取若干典型断面,对既有浅埋隧道受不同厚度的填土影响进行数值分析,并确定容许填土厚度。结果表明:既有隧道上方填土将导致衬砌整体下沉,左右两侧沉降基本对称,位移值自上而下逐渐减小;填土后的安全系数降低,但幅度不大,拱脚及仰拱处安全系数偏小,可能出现开裂;既有隧道拱顶位移值随着填土厚度的增加而近似线性增大,为满足位移控制要求,容许填土厚度应为0.3 H^0.4 H(H为原覆土厚度)。根据若干断面的分析结果可得整个填土区域的容许填土线,在此范围内进行填土施工,并采取相应的工程措施,既有隧道的运营安全可得到保证。本分析方法简单易行,满足工程精度,可用于指导工程实践,对类似工程有一定的借鉴意义。

Significance of hepatitis virus infection in the oncogenicinitiation of hepatocellular carcinoma

World Journal of Gastroenterology 2016年第4期22卷 1497-1512页

Hepatocellular carcinoma(HCC) is one of the most common causes of cancer-related death worldwide. Chronic infection of hepatitis B virus(HBV) and/or hepatitis C virus(HCV) is a major risk factor in the development of the HCC, independently from excessive alcohol abuse and metabolic disease. Since the biology of HBV and HCV is different, their oncogenic effect may go through different mechanisms, direct and/or indirect. Viral hepatitis infection is associated with cellular inflammation, oxidative stress, DNA damage, that may lead to subsequent hepatic injuries such as chronic hepatitis, fibrosis, cirrhosis, and finally HCC. Direct oncogenic properties of these viruses are related with their genotypic characteristics and the ability of viral proteins to interact with host proteins, thus altering the molecular pathways balance of the cells. In addition, the integration of HBV DNA, especially the gene S and X, in a particular site of the host genome can disrupt chromosomal stability and may activate various oncogenic mechanisms, including those in hematopoietic cells. Recently, several studies also had demonstrated that viral hepatitis could trigger the population of hepatic cancer stem cells. This review summarize available pre-clinical and clinical data in literature regarding oncogenic properties of HBV and HCV in the early initiation of HCC.

Asian Journal of Andrology 2009年第3期11卷 342-350页

作者： Hyun Jung park Won Young Lee Jin Hoi Kim Jae Hwan Kim Hun Jong Jung Nam Hyung Kim Bo Kyung Kim Hyuk Song Department of Animal Science College of Natural Science Konkuk University Chung-ju 380-701 Korea CHA Stem Cell Institute Graduate School of Life Science and Biotechnology Pochon CHA University Seoul 135-907 Korea Department of Animal Biotechnology College of Animal Biotechnology Konkuk University Seoul 143-701 Korea Occupation and Environment Department Medical School Konkuk University Chung-ju 380-704 Korea Department of Animal Science College of Agriculture Chungbuk National University Choung-ju Chung-buk 361-763 Korea Department of Physiology Medical School Konkuk University Chung-ju 380-701 Korea

The purpose of this study is to establish a gene delivery system for interstitial tissue-specific protein expression in mice testes using modified recombinant baculovirus. Green fluorescent protein （GFP）-expressing recombinant baculovirus （GFP-baculovirus）, in which the insect cell-specific polyhedron promoter was replaced by the cytomegalovirus （CMV）-ie promoter, was used to transfect testicular cells in vitro, and for intra-tunica albuguineal injection of the interstitial tissue of the testis. GFP expression was monitored in frozen testes sections by fluorescence microscopy. Expression of GFP in testicular tissues was also assessed by reverse transcription polymerase chain reaction （RT-PCR）, and protein expression was assessed by Western blot. Testicular cells in vitro were infected efficiently by modified recombinant GFP-baculovirus. lntra-tunica albuguineal injection of GFP- baculovirus into the mouse testis resulted in a high level of GFP expression in the interstitial tissues. RT-PCR analysis clearly showed GFP gene expression in the testis, particularly interstitial tissues. Intra-tunica albuguineal injection of a modified baculovirus that encoded recombinant rat insulin-like growth factor binding protein （IGFBP）-5 resulted in an increase in IGFBP-5 in testis and semen. In conclusion, we have developed an efficient delivery system for gene expression in vivo in testicular cells, particularly cells of the interstitial tissue using intratunica albuguineal injection of a modified recombinant baculovirus. This method will be particularly relevant for application that requires gene delivery and protein expression in the testicular cells of the outer seminiferous tubule of the testis.

＜正＞The multimodality medical image fusion plays an important role in clinical applications which can support more accurate information for physicians to diagnose *** this paper,a new fusion scheme for computed tomography and magnetic resonance images based on wavelet analysis is *** the images are decomposed by wavelet transform,the low frequency coefficients are performed with the maximal absolute values followed by verifying their consistency,and the high frequency coefficients are selected by a maximal local variance *** resultant image is then reconstructed by using the inverse wavelet transform with the combined wavelet coefficients. The performance of our method is qualitatively and quantitatively compared with some existing fusion approaches. Experimental results show that the proposed method can preserve more useful information and with higher spatial resolution.
