We also collected the authors' research papers related to this area in the recent years.DATA SELECTION: We selected 24 research articles on organizational reforms, leadership behavior, motivation mechanism and organizational culture.DATA EXTRACTION: Seventeen out of the 24 articles were excluded because they overlapped with each other in content to some extent. Therefore,this article reviewed the other 7.DATA SYNTHESIS: On the basis of comprehensive analysis of development of managerial psychology at home and abroad, this article predicts the newly emerging hot issues and trend of research on managerial psychology, and further puts forward the short-term and long-term development goals of managerial psychology research.CONCLUSION: Paying attention to research on organization-level changes,accentuating on the systematic exploitation of human resources, continuously expanding research field and giving more concern for the national goals are the development trend of managerial psychology.

Objective To study the internal atlas sphincter of rats with congenital anorectal malformations(ARM)by observing the number of the ganglion cell and the number of nerve plexus in the internal sphincter.Methods Healthy pregnant Wistar- Imammichi rats are induced to ARM by ETU.67 rats with ARM were obtained.The pelvis was continuously cut from the exactly midsagittal plane, and the slices were stained with HE to observe the number of the ganglion cell and the number of nerve plexus in the internal sphincter under microscope.Result The average number of the ganglion cell in the rats with ARM was 1.206,and the number of the nerve pluxes is 0.310.The numbers in both two groups were extremely less than that in normal rats(P＜0.05).The rats without ARM which were also dealt with ETU had no distinctness compared with the normal rats.Conclusion The pathology changes of ARM includes many ways,for example,muscles,mucosa and the nerve system.The decrease of the ganglion cell and the nerve plexus in internal sphincter is an important aspect of ARM.

Purpose With the progression of brain tissue aging, the transport and drainage characteristics of metabolites and secretory products for neurons in extracellular space occurs irreversible change. This paper aims to investigate and quantify MR tracer diffusion characteristics in cerebral interstitial fluid of elderly SD rats. Materials and Methods MR contrast agent Gd-DTPA was injected into the caudate nucleus of two groups of rats including 8 in experimental group (15-17 month old) and 15 in control group (7-10 month old). MR scan was performed at 0.25 h, 0.5 h, 1 h, 2 h, 3 h and 4 h to observe the dynamic distribution in the caudate and measure the diffusion and clearance rate. Results There was no statistically significant difference in diffusion rate and D* between control group with (3.32±0.70)×10-4 mm2/s and experimental group with (3.25±0.46)×10-4 mm2/s (t=1.739, P>0.05). The clearance rate k' was significantly different between control group (0.62±0.12)×10-4/s and experimental group (0.29±0.08)×10-4/s (t=11.602, P<0.05). Conclusion The degeneration of aging brain tissue changes the composition of extracellular space resulting in decreased speed of ISF clearance. This may cause accumulation of metabolites which eventually triggers a variety of age-related diseases.

Objective: Pocket infection in patients after total removal of implanted pacemaker has many problems for their electronic system; our research intends to explore the feasibility of conservatively treating such infection and retain the electronic system. Methods: A total of 4 patients with pacemaker pocket infection in our hospital from 2015-01 to 2016-02 were studied. Thorough debridement and disinfection were conducted in infected pockets and devices, meanwhile vacuum sealing drainage was applied. Electrode wire was kept and intravenous antibiotics were given for (7-10) days after the operation in all patients. Results: The average time of infection occurred at 14.75 months after operation with the type of isolated pacemaker pocket infection. Pocket vacuum suction drainage was performed, with the mean of 7.25 (5-10) months follow-up observation, infection was disappeared and the patients had good wound healing. Conclusion: With thorough debridement of infected pocket, rational treatment of residual electronic system and vacuum sealing drainage, the infection might be effectively controlled for complete recovery without lead extraction in relevant patients.
