Objective To investigate the possibility of utilizing the mixed bacteria liquid and the Escherichia coli ( E.coli) liquid to establish the chronic salpingitis model of New Zealand rabbits, respectively.Methods Taken as the study object, the un-pregnant New Zealand rabbits (4~5 years old) were randomly divided into three groups: the normal group, the mixed bacteria experimental group and the E.coli experimental group.The trans-vaginal intrauterine intubation operation was performed for the injection of the mixed bacteria liquid and the E.coli liquid.Visual observation was to evaluate the gross pathological changes of the salpingitis and the pelvic cavity.HE staining and the light microscope were used to observe the micro-pathological changes of salpingitis.Results On the 15th day after modeling, increased pelvic effusion, dense peritoneal adhesion, interstitial hyperplasia and infiltration of lymphocytes were observed in both experimental groups. Conclusion Through the trans-vaginal intrauterine intubation operation, the chronic salpingitis model of New Zealand rabbits could be successfully established either by using the mixed bacteria liquid or by using the E.coli liquid.

Objective To explore the characteristics and data collection sources of featured literature databases in universities/colleges in Yunnan in order to provide evidence for building featured literature databases. Methods Key information about three types of featured literature databases was retrieved online, which included those being constructed jointly by some universities or colleges in Yunnan, owned by universities or colleges in Yunnan, and already in use in China Academic Library and Information System ( CALIS) , respectively. Comparison was performed among these featured literature databases in regard to data characteristics and collection sources. Results Among all the featured databases being constructed, 58.8% were based on literature on local resources, 17.6% on disciplines and specialties, and 11.8% on library literature. In-use featured databases in Yunnan were mainly based on local resources and disciplines, and the data were collected within their own organizations or through multi-sources. The featured databases in CALIS were of local resources, disciplines, and people, while their data were collected mainly within their own organizations, through other organizations and multi-sources. Conclusion Yunnan featured databases are of unique characteristics, but more should be done to define Yunnan style data, while it is necessary to collect data from a wider range of sources.

Magnetic Resonance Imaging(MRI)technology can directly show the changes of brain network and explain the central mechanism of Tai Chi remodeling of brain structure and function.In this paper,we collected the domestic and foreign research on the influence of Tai Chi movement on the brain network by using MRI technology,and combed it from the perspective of brain structure and function changes.The results revealed that Tai Chi may promote memory function,cognitive flexibility,inhibitory control,and working memory capacity by remodeling the structure and function of the medial temporal lobe and prefrontal cortex in older adults,which may be a potential central mechanism for Tai Chi to improve memory and cognitive control in the elderly.However,there are some problems in the current research,such as small sample size,insufficient long-term follow-up,and difficult evaluation of exercise intensity.It is necessary to carry out large-sample and long-term detailed research to further verify the current research results.
