Neurogenic bladder is a dysfunction of the lower urinary tract caused by nervous system disor- der. We investigated the trends in publication of articles under the topic ＂neurogenic bladder＂ using bibliometric analysis. Articles on neurogenic bladder, published between 1995 and 2014, were retrieved from the ISI Web of Science citation database. We analyzed the search results for authors, countries, institutions, journals, and top-cited papers. A total of 1,904 articles were re- trieved. There was a small increase in the number of articles on neurogenic bladder from 1995 （n = 43） to 2014 （n = 117）. The USA was the leading country in the total number of articles （n = 598）. However, the number of publications from China has rapidly increased, and China was ranked second in 2014. Emmanuel Chartier-Kastler （n = 65） was the most productive author, and University of Paris VI （Paris 6）（n = 61） was the most productive institution. The Journal of Urology published the greatest number of artides on this topic （n = 285）. Articles on neurogenic bladder were often published in a professional journal under the category Urology ＆ Nephrology, Neurosciences ＆ Neurology, or Rehabilitation. Visualization analysis based on co-citation networks was conducted using CiteSpace III. Visualization analysis revealed that the hot spots in neurogenic bladder were botulinum toxin-A, prazosin, bethanechol, and afferent pathways. These findings provide new insight into the publication trends and hot spots in neurogenic bladder.

AIM:To investigate the clinicopathological features and prognostic value of lysine specific demethylase 1(LSD1) in hepatocellular carcinoma(HCC).METHODS:We examined LSD1 expression in 60 paired liver cancer tissues and adjacent noncancerous tissues by quantitative real time polymerase chain reaction(qRT-PCR) and Western *** addition,we analyzed LSD1 expression in 198 HCC samples by *** relationship between LSD1 expression,clinicopathological features and patient survival was ***:Immunohistochemistry,Western blotting,and qRT-PCR consistently confirmed LSD1 overexpression in HCC tissues compared to adjacent non-neoplastic tissues(P < 0.01).Additionally,immunostaining showed more LSD1-positive cells in the higher tumor stage(T3-4) and tumor grade(G3) than in the lower tumor stage(T1-2,P < 0.001) and tumor grade(G1-2,P < 0.001),***,HCC patients with high LSD1 expression had significantly lower 5-year overall survival rates(P < 0.001) and lower 5-year disease-free survival rates(P < 0.001),respectively.A Cox proportional hazards model further demonstrated that LSD1 over-expression was an independent predictor of poor prognosis for both 5-year disease-free survival [hazards ratio(HR) = 1.426,95%CI:0.672-2.146,P < 0.001] and 5-year overall survival(HR = 2.456,95%CI:1.234-3.932,P < 0.001) in ***:Our data suggest for the first time that the overexpression of LSD1 protein in HCC tissues indicates tumor progression and predicts poor prognosis.

AIM： To determine the accuracy of high-resolution magnetic resonance imaging （MRI） using phasedarray coil for preoperative assessment of T staging and mesorectal fascia infiltration in rectal cancer with rectal distention.METHODS： In a prospective study of 67 patients with primary rectal cancer, high-resolution magnetic resonance imaging （in-plane resolution, 0.66 × 0.56） with phased-array coil were performed for T-staging and measurement of distance between the tumor and the mesorectal fascia. The assessment of MRI was compared with postoperative histopathologic findings. Sensitivity, specificity, accuracy, positive predictive value, and negative predictive value were evaluated.RESULTS： The overall magnetic resonance accuracy was 85.1% for Tstaging and 88% for predicting mesorectal fascia involvement. Magnetic resonance sensitivity, specificity, accuracy, positive predictive value, and negative predictive value was 70%, 97.9%, 89.6%, 93.3% and 88.5% for ≤ T2 tumors, 90.5% , 76% , 85.1%, 86.4% and 82.6% for T3 tumors, 100%, 95.2%, 95.5% , 62.5% and 100% for T4 tumors, and 80% , 90.4%, 88%, 70.6% and 9d% for predicting mesorectal fascia involvement, respectively.CONCLUSION： High-resolution MRI enables accurate preoperative assessment for T staging and mesorectal fascia infiltration in rectal cancer with rectal distention.

Burial dissolution of feldspar and carbonate minerals has been proposed to generate large volumes of secondary pores in subsurface reservoirs. Secondary porosity due to feldspar dissolution is ubiquitous in buried sandstones;however, extensive burial dissolution of carbonate minerals in subsurface sandstones is still debatable. In this paper, we first present four types of typical selective dissolution assemblages of feldspars and carbonate minerals developed in di erent sandstones. Under the constraints of porosity data, water–rock experiments, geochemical calculations of aggressive fluids, diagenetic mass transfer, and a review of publications on mineral dissolution in sandstone reservoirs, we argue that the hypothesis for the creation of significant volumes of secondary porosity by mesodiagenetic carbonate dissolution in subsurface sandstones is in conflict with the limited volume of aggressive fluids in rocks. In addition, no transfer mechanism supports removal of the dissolution products due to the small water volume in the subsurface reservoirs and the low mass concentration gradients in the pore water. Convincing petrographic evidence supports the view that the extensive dissolution of carbonate cements in sandstone rocks is usually associated with a high flux of deep hot fluids provided via fault systems or with meteoric freshwater during the eodiagenesis and telodiagenesis stages. The presumption of extensive mesogenetic dissolution of carbonate cements producing a significant net increase in secondary porosity should be used with careful consideration of the geological background in prediction of sandstone quality.

Understanding the relationship between the timing of N fertilizer applications and crop primary production is crucial for achieving high yield and N use efifciency in agriculture. This study investigated the effects of starting-N plus topdressing N applications （as compared to the common practice of all basal application） on soybean photosynthetic capacity under different planting densities. A ifeld experiment was conducted in two growing seasons （2011 and 2012）, and the soybean （Glycine max L. Merrill） cultivar was Dongnong 52, three planting densities （20, 25 and 30 plants m-2）, and four N fertilizer application patterns （all N fertilizer of 6 g N m-2 as basal fertilizer, all N fertilizer as topdressing at beginning pod stage （R3）, 1.8 g N m-2 as basal fertilizer and 4.2 g N m-2 as topdressing at stage R3 and full pod stage （R4）, respectively）. The results indicated that under the same planting density, compared to applying all N as basal fertilizer, the application of starter-N plus topdressing N substantially reduced the rate of pod abscission, and enhanced leaf area index （LAI） signiifcantly at beginning seed stage （R5）（P〈0.05）, net assimilation rate （NAR） during stages R4-full seed stage （R6）（P〈0.05）, contribution rate of post-seed iflling assimilate to seed （CPA）（P〈0.05）, and yield （P〈0.05）. Applying topdressing N at stage R4 resulted in higher net primary production and yield than applying topdressing N at stage R3. When applying starter-N plus topdressing N at planting density of 25 plants m-2, LAI after stage R5 and NAR after stage R4 were increased by 5.92-16.3%（P〈0.05） and 13.7-26.6%（P〈0.05） with the planting density of 20 plants m-2, respectively, and yield was 8.46-14.0%（P〈0.05） higher than that under 20 plants m-2. When planting density increased to 30 plants m-2, only LAI during stages R4-R5 and NAR during stages R4-R5 increased by applying starter-N plus topdressing N, while the other indexes declined. Overall, results of this study demonstrated
