Through the analysis of the status quo of lack of medical students′humanistic quality , this paper discussed the current increase medical students humanities quality:the necessity of the development of the harmoni-ous society needs , remarkable physician training needs , the growth of self-actualization needs .This paper pointed out that under the perspective of cultural consciousness of medical students improve humane quality way :accurate positioning “self-improvement” action subject , sets up the “benevolence” goal, integration of domestic and for-eign high-quality learning resources , learning to use new media network platform , improving “knowledge and ac-tion should go hand in hand” in practice.

Objective Compare the value of multislice CT perfusion imaging (MSCTPI)?color brain atlas (CBA)?visual evoked potential mapping (VEP-M) in the diagnosis of acute cerebral infarction.Methods After routine CT was performed,the 27 cases of acute cerebral infarction underwent MSCTPI?CBA?and VEP-M respectively.Results The examination of MSCTPI showed that abnormal perfusion changes were in accordance with clinical symptoms;the examination of CBA showed that in 32 scale local high power shadow presented on the power of ??? of lesion;the examination of VEP-M showed the prolongation of latency of P100?degrade of amplitude on the lesion of the chart,the power of the lesion degraded obviously on the map of distribution of power,and distribution asymmetry.Conclusion Combined use of MSCTPI?CBA?VEP-M in the diagnosis of acute cerebral infarction can remedy the defects and improve diagnostic rate of acute cerebral infarction further.

Objective: To study the effects of enzymolytic extracts of abalone (EEA) on memory of mice, and compared with water extracts of abalone (WEA). Methods: Mice were given EEA or WEA once daily lasting 10 d. Their step-down latency (SDL) and escape latency (EL) in a passive avoidance , and food-hunting time in a maze were determined. Results: EEA 2-8 ml/kg lengthened SDL by 13.7 %-105.3 %, shortened EL by 40.0 %-60.0 % and food-hunting time by 28.3 %-49.4 %, in a dose-dependent manner. EEA reversed ethanol-induced disturbance of memory retrial in a passive avoidance and NaNO2-induced disruption of memory retention in a passive avoidance and maze. Significant action of WEA was not observed until the dose of WEA was increased to 8 ml/kg. Conclusion: EEA improves learning and memory, more effective than WEA.

ObjectiveTo study the efficacy of using multileaf collimators with different position and different degree in the treatment of nasopharyngeal carcinoma (NPC) using intensity-modulated radiotherapy techniques.Methods Ten patients withNPC were administered andanalyzed.Thepenumbra characteristics, dose of target, and radiation conformal indexes (CI) of mode T1 and mode T2 were measured and compared using dose volume histogram generated by Varian Eclipse three-dimensional planning computer system. Mode T1 :The angles of seven coplanar beams were 0°, 52°, 106°, 160°, 212°, 258°and 308°,respectively. There were no restriction on the position and degree of multileaf collimators. Parameters were set and optimized. Mode T2 :The beam angles and the parameters were as same as mode T1. According to the actual situations, the position and the degree of the multileaf collimators were changed. Then thedose optimization was performed. Results Target dose coverage in both mode T1 and T2 could be clinically accepted, and the CI were 0. 82 and 0. 83(t = -0. 25, P =0. 815). The maximum dose reductions in the lens, eyes, optic nerves and corneas were 28. 7% (t = 4. 80, P = 0. 000), 2. 7% (t = 2. 99, P = 0. 021),1.4%(t= 1.05,P=0.032), and 30.5% (t=2.99,P=0. 020), respectively. However, the mean dose and V35 of the parotid were increased by 0. 6% (t = - 2. 82, P = 0. 043) and 9.9% (t = - 2. 05, P =0. 038). ConclusionsOpimization of multileaf collimators can reduce the scattering and leaking rays. Compared with mode T1 ,controlling the position and degree of multileaf collimators could reduce the radiation dose to the eyes and optic-nerves, especially to the lens.
