After the evolution history of medical information science in China was briefed, the current situation in training master of information science was analyzed , the training programs in Huazhong University of Science and Technology , Central South University and Jinan University were compared , with certain suggestions put forward for the solution of problems in training master of information science .

Objective: To evaluate the efficacy of the bispectral index (BI) in predicting patient movement on skin incision under sevoflurane anesthesia with the PK statistic. Method: Twenty-nine adult patients. scheduled for elective upper abdominal surgery, were selected. Anesthesia was induced with propofol and 4%-5% sevoflurane in oxygen and maintained with one of four randomized sevoflurane concentrations (0.6MAC, 1.0MAC. 1.5MAC and 2.0MAC) for fifteen minutes, then skin incision was performed by the surgeon at the planned site of the surgery, and each patient was observed carefully about 2 minutes to detect purposeful movement. The data of BI, 95% SEF, MAP, SABP and HR in one minute before skin incision were applied to statistically analysis. Result: The P_K was significantly greater than 0.5 for the sevoflurane level and the BI. The PK of 95% SEF. SABP and MAP were less than that of the level of sevoflu or Bl. but was significantly greater than 0.5 The P_K of HR was close to 0.5. Conclusion: These indicators of B, BP and 95% SEF may predict patient movement to skin incision under sevoflurane anesthesia. of which the BI is the most sensi tive.

Objective:To observe the effect of bacteroides fragilis BF839 intervention on learning, memory and social novelty of fragile X-mental retardation gene 1 ( Fmr1) knockout (KO) mice. Methods:Thirty three-week-old Fmr1 KO mice were randomly divided into Fmr1 KO group ( n=15) and Fmr1 KO+BF839 group ( n=15). Mice in the Fmr1 KO group freely drank autoclaved tap water everyday; mice in the Fmr1 KO+BF839 group drank BF839 bacterial liquid (10 mL/d) everyday;11 wild-type mice freely drank autoclaved tap water everyday were set as controls (WT group). After 4 weeks of intervention, Morris water maze test was used to observe the differences in escape latency and frequencies of crossing the original platform among mice in each group; Three-chamber Social Interaction Test was used to observe the differences in contact frequencies and contact durations with unfamiliar mice among mice in each group. Results:On the 4 th d of experiment, the escape latency of mice in the Fmr1 KO group ([46.06±10.29] s) was significantly longer than that in the WT group ([33.39±12.02] s, P<0.05); the escape latency of mice in the Fmr1 KO+BF839 group ([28.39±9.07] s) was significantly shorter than that in the Fmr1 KO group ( P<0.05); the escape latency of mice in the Fmr1 KO+BF839 group was slightly shorter than that in the WT group without significant difference ( P>0.05). The frequencies of crossing through the original platform of mice in Fmr1 KO group (0.00[0.00, 1.00] time) was slightly less than that in WT group (1.00 [0.00, 1.00] time) without significant difference ( P>0.05); that in the Fmr1 KO+BF839 group (1.50[1.00, 2.00] times) was significantly larger than that in the Fmr1 KO group and WT group ( P<0.05). The contact frequencies of the mice in the Fmr1 KO group with unfamiliar mice (5.50[0.50, 12.75] times) was less than that in the WT group (7.00[4.00, 17.00] times) without significant difference ( P>0.05); that in the Fmr1 KO+BF839 group (23.00[16.00, 36.00] times) was significantly increased as compared with that in the Fmr1 KO group and WT group ( P<0.05). The contact duration of mice in the Fmr1 KO group with unfamiliar mice (9.50[0.50, 41.95] s) was significantly shorter than that in the WT group (142.00[65.00, 171.60] s, P<0.05); Fmr1 KO+BF839 group had significantly longer contact duration with unfamiliar mice (69.60 [50.40, 98.40] s) than Fmr1 KO group ( P<0.05); the contact duration of mice in Fmr1 KO+BF839 group with unfamiliar mice was shorter than that in WT group without significant difference ( P>0.05). Conclusion:Early BF839 intervention can significantly improve the learning, memory abilities and social novelty of Fmr1 KO mice, and even restore the Fmr1 KO mice to normal levels, which suggests that BF839 may become a new tool for treatment of fragile X syndrome and autism.

Trauma is the leading cause of death for people under 40 years old in the world. At present, the rescue and treatment system of trauma patients in China is not yet well established, and the mortality of trauma patients is higher than those in the developed countries. Improving the treatment system is the key to reducing the trauma mortality. In order to innovate the service mode of trauma first aid, further promote the establishment of regional trauma first aid system, improve the ability of trauma treatment, reduce the mortality and disability rate of trauma patients in Jiangxi Province, recently Health Commission of Jiangxi Province and the First Affiliated Hospital of Nanchang University have reached a consensus on the establishment of Jiangxi trauma first aid center. In order to provide reference for the construction of trauma treatment system, the author analyzes the following aspects including functional positioning, basic requirements, organization management, and evaluation of core indicators.
