Effect of Qianliexin capsule on quality of life, NIH-CPSI score and IIEF-5 score in patients with prostatitis complicated with erectile dysfunction

Purpose: To study the influence of Qianliexin capsule on quality of life, NIH-CPS Index, and 5-item version of the 15-item International Index of Erectile Function (IIEF-5) scores in patients with prostatitis complicated with erectile dysfunction (ED).Methods: Patients with prostatitis complicated with ED (128) who were treated from November 2015 to December 2017 participated in this study. The patients were assigned to two groups (64 per group) according to the treatment given: study group which was given routine treatment plus Qianliexin capsule, and control group which received routine treatment only. Clinical effectiveness, adverse reactions, Quality of Life-Bref (QOL-BREF) scores, etc, of the two groups were determined.Results: The QOL-BREF score of the study group was significantly higher than that of the control group (p < 0.05). While NIH-CPSI scores were significantly decreased in both groups, the decrease in the study group was lower (p < 0.05). In contrast, IIEF-5 score significantly increased in both groups, but the increase in the study group was higher than in control (p < 0.05).Conclusion: Qianliexin capsule is an effective and reasonably safely drug for enhancing the quality of life, NIH-CPSI and IIEF-5 scores, as well as the lecithin bodies in prostatitis patients with ED.Keywords: Qianliexin capsule, Prostatitis, Erectile dysfunction NIH-CPSI score, IIEF-5 scor

Defining Urban Boundaries by Characteristic Scales

Defining an objective boundary for a city is a difficult problem, which remains to be solved by an effective method. Recent years, new methods for identifying urban boundary have been developed by means of spatial search techniques (e.g. CCA). However, the new algorithms are involved with another problem, that is, how to determine the characteristic radius of spatial search. This paper proposes new approaches to looking for the most advisable spatial searching radius for determining urban boundary. We found that the relationships between the spatial searching radius and the corresponding number of clusters take on an exponential function. In the exponential model, the scale parameter just represents the characteristic length that we can use to define the most objective urban boundary objectively. Two sets of China's cities are employed to test this method, and the results lend support to the judgment that the characteristic parameter can well serve for the spatial searching radius. The research may be revealing for making urban spatial analysis in methodology and implementing identification of urban boundaries in practice.Comment: 26 pages, 5 figures, 7 table
