1.Non-coding RNAs and erectile dysfunction: An update.
National Journal of Andrology 2016;22(2):160-164
Erectile dysfunction (ED) is a disease associated with a variety of factors such as age, psychological factors, physical conditions, and lifestyle, and it severely affects the patients quality of life. In the past, some non-coding RNAs (ncRNAs) transcribed by genes but not translated into the protein were regarded as the "waste" in the process of gene expression. But in the recent years, ncRNAs have been found to play a crucial role in regulating gene expression and its products, which may affect penile erectile function. This review focuses on the recent progress in the studies of the relationship between ncRNAs and erectile dysfunction.

2.Exploration of establishment of medical information technology curriculum system
Chinese Journal of Medical Education Research 2013;(8):785-788,789
Principles of constructing medical information technology curriculum system were pro-posed revolving round the core problem of how to combine needs of developing life science with culturing talents who can independently apply information technology knowledge in studying and researching. De-tailed implementing measures for constructing medical information technology curriculum system were summarized after repeated practical teaching. Longitudinal classification based on discipline and trans-verse classification based on teaching level were combined to construct the whole standard course. Finally, courses were appropriately distributed according to detailed culturing objectives for students in medical universities and colleges,thus a suitable medical information technology curriculum system in medical universities and colleges was formed.

Objective:To construct the Helicobacter pylori infected C57BL/6 mice model to observe the activation of NOD1/NF-κB signaling pathways in the gastric tissues,and study its roles in inflammatory response during Hp infection.Methods:6-8 week-old C57BL/6 mice were randomly divided into two groups,the Hp infection group and the control group,and mice were given by gavage every 48 h for five times with Hp or PBS,respectively.All the animals were sacrificed at different time point and the gastric tissue were stained with hematoxylin-eosin( HE);The mRNA expression of NOD1 and RIP2 in gastric tissues were examined by RT-PCR;Levels of IFN-βand IP-10 in mice serum were assessed by ELISA;Nuclear translocation of p65 in gastric tissue was detected by Western blot.Results:Hp infection elicits an inflammatory cell response,glands in gastric tissue were reduced or atrophic,as compared with that in the control group.The levels of IP-10 and IFN-βincreased in the model group, and peaked at 16 weeks after Hp infection.Hp infection increased the mRNA expression of NOD1 and the p65 content in nuclear between 24-120 h(P<0.05),and the highest level at 48 h,subsequently the expression levels were began to decrease.The mRNA expression level of RIP2 was up-regulated after Hp was administrated, peaked at 48 h and declined after 72 h.However, the expression levels would rise again at 120 h.Conclusion: Hp infection can activate the NOD1/NF-κB signaling pathways and induce the production of IFN-βand IP-10 in gastrics of mice.

Objective ST-T complex change, which represents the ventricle repolarization phase, is the main clinical indicator in detecting myocardial ischemia (MI) based on electrocardiogram (ECG) signals.However, its feature point location is not accurate due to interferences. In this paper, a new approach about myocardial ischemia analysis was proposed based on QRS complex. Methods QRS complex, representing the ventricle depolarization process, was used to analyze myocardial ischemia, and some parameters were extracted synthetically in time domain. Then they were used for statistical analysis of myocardial ischemia states and non-myocardial ischemia states. Results Five parameters had significant differences after verification of Non-MI signals in MIT-BIH database and MI signals in long-term ST database (LTST) and they were: QRS upward and downward slopes, transient heart rate, R angle and Q angle in a triangle QRS. Conclusion Five parameters extracted from QRS complex had significant differences. The proposed method provides an important basis for myocardial ischemia detection.
