As a kind of mineral medicine containing mercury, the toxicity of Cinnabaris has always been controversial. In recent years, along with the increasing reports and studies on Cinnabaris, it has been found that although the toxicity of Cinnabaris has effects on multi-systems, the main effect is on nervous system. In order to clarify Cinnabaris neurotoxicity and reduce its damage for nervous lesion caused in clinical application, this article made a thorough analysis on symptom expression and mechanism of Cinnabaris neurotoxicity and put forward corresponding countermeasures.

Objective To study the relationship of implicit memory and amnesia effect of oral midazolarn premedication and toobserve its anterograde amnesia, the effect on short-term memory and the onset time and out come of retrograde amnesia. Methods60 patients with ASA I - Ⅱ status undergoing abdomen and limb operations were divided into 3 groups with 20 cases each. Group A:oral midazolam 7.5mg;Group B:oral 15mg;Group C:placebo. The patients received combined spinal-epidural anesthesia after oral midazolam. The parameterns of EEG, SEF 95 %, BISwere collected at the same time and the degree and remark of sedation were dome according to OAA/S. The amnesia and implicit memory were investigated with pictures and muddy identified hearing rate 6 hours after operation. Results (1)Twenty min following drug ad dministration the remarks of sedation of group A and B were significantly loWver than that before and that of group C, Which was not significently different between group A and B. ( 2)The amnesia rates tested six hrs after surgery were significantly higher at 30min in group A, 20min in group B than those before treatment and were kept at 70%-80% levels, which in group C was remained zero. (3)The muddy identified hearing rate was not different significantly, among the three groups. (4) The short-term memory was all 100%during the period of drug action. (5)BIS and SEF 95% Were lower 30min after the treatment and all kept at 80 Hz and 20 Hz, which were not different remarkably between group A and B. ConclnsionOral midazolam 7. 5mg has a good effect on anterograde amnesia 30min after treatment, which may not be improved with increament in dosage. It does not lead to retrograde amnesia. The long-term memory, but not short-term memory, was impaired by midazolam. It only affects the explicit memory. Oral premnedication with midazolam can not prevent the awareness during operation totally.

0bjective To investigate the serum total bilirubin level of healthy population in northwest area of China.Methods According to the guiding principle and the screening standard of C28-P3,722 individuals conforming to the screening standard from October 2011 to January 2012 were collected.Serum total bilirubin was determined with diazo reagent method(Roche)on the P module of Hitachi 7600 automatic biochemistry analyzer,and the vanadate reagent method(WAKO)on the D module of the Hitachi 7600 automatic biochemistry analyzer,respectively.The detection results were analyzed between different analysis systems,between country and city and among different age groups by SPSS13.0.The top and bottom limitations of 95% reference interval recommen-ded by the C28-P3 file were calculated by the non-parametric method.Results Serum total bilirubin detection results had no statis-tically significant differences between the two kinds of detection methods,between rural and urban populations,among all ages and genders (P >0.05).The ultimate reference interval of serum total bilirubin in the northwest area was 2.19 -29.29 μmol/L.Con-clusion The differences of serum total bilirubin reference interval exist between the healthy population in the Northwest area of China and the current reference interval used in domestic and foreign population.Establishing the reference intervals of new bio-chemical test item suitable for China′s population will provide the scientific basis for the evaluation of disease diagnosis,treatment, prognosis judgment and health assessment in the Chinese population.

ObjectiveTo explore the correlation between psychologic status and personality characteristics of certain recruits.Methods168 recruits were surveyed by Symptom Checklist 90 (SCL-90) and Eysenck Personality Questionnaire (EPQ).ResultsIn 168 recruits, the factorial scores including interpersonal sensitivity, hostility and phobia were higher than the norm of Chinese and PLA (P<0.05～0.01). In junior high school recruits, the factorial scores including hostility and constrain were higher than the senior school recruits (P<0.05). Certain recruits showed higher scores of factor P, factor N, and lower scores of thinking factor, factor E and factor L and all the factors of SCL-90 compared with the norm of Chinese.ConclusionThe mental status and personality characteristics of certain recruits are poor. The company should strengthen psychological education and quickly adapt the recruits to the military circumstance.

Objective To explore the effect of electromyogram-triggered neuromusclar stimulation (ETNS) on motor function of upper limbs of stroke patients. Methods 45 stroke patients from July, 2011 to December, 2012 in China Rehabilitation Research Center were randomly divided into control group (n=15), neuromuscular electrical stimulation (NMES) group (n=15) and ETNS group (n=15). 3 groups were given routine medication and rehabilitation treatment. They were assessed with the largest surface electromyography (sEMG), Simple Test for Evaluating Hand Function (STEF), and modified Barthel Index before and after treatment. Results After treatment, the range of sEMG of extension carpi radialis and STEF improved in three groups (P<0.05). NMES group and ETNS group were better than the control group (P<0.05), and ETNS group was better than NMES group (P<0.05). The scores of modified Barthel Index rose (P<0.05), NMES group and ETNS group were better than the control group (P<0.05). Conclusion Both NMES and ETNS can improve the motor recovery of upper limbs after stroke, and ETNS is more effective.

The factors affecting cerebral ischemia model of rat established by middle cerebral artery occlusion include animal selection, drugs of anesthesia, surgical site, thread affect building, and etc. To find and manufacture an appropriate thread is the key to success. It includes the species, length, diameter, hardness, and placing method of the thread. The improvement of these factors greatly increases the successful rate in the establishment of focal cerebra ischemia model of rat caused by middle cerebral artery occlusion.

Based on ninety three acetylcholinesterase inhibitors (AChEIs) which have the same mechanism of action but are different in structural characteristics, the pharmacophore model for acetylcholinesterase inhibitor was constructed by the CATALYST system. The optimal pharmacophore model with three hydrophobic units, a ring aromatic unit and a hydrogen-bond acceptor unit were confirmed (Weight=3.29, RMS=0.53, total cost-null cost=62.75, Correl=0.93, Config=19.05). This pharmacophore model will act on the double active site of acetylcholinesterase and is able to predict the activity of known acetylcholinesterase inhibitors that are used for clinical treatment of Alzheimer's disease (AD), and can be further used to identify structurally diverse compounds that have higher activity treating with Alzheimer's disease (AD) by virtual screening.

Objective Through the research on relationship between achievement motive and personality traits,to provide the basis theory of personality attributes for selecting outstanding medical professional scientifically and effectively,and give some advice for improving medical education mode.Method The 310 medical staffs in sample hospital were treated as the research object in October 2015,who were randomly investigated with the big five personality questionnaire and achievement motivation scale,among of which,valid questionnaires were 290 copies leading to 93.5％ effective rate.SPSS 17.0 software was used to make t test,Chi-square analysis and correlation analysis for the data of the recover valid questionnaires.Result ①Personality traits of friendliness and rigor of the medical staffs of different gender exist statistically significant difference (t=-7.39,P=0.00;t=-8.28,P=0.00) and there were significant differences in the openness and rigor of medical staffs of different gender (P＜0.05).②The achievement motivation level of male medical staffs was higher than that of female (P=0.00),and there was no significant difference in achievement motivation among medical staffs.③The personality trait of neuroticism was negatively correlated with the pursuit of success and achievement motivation (correlation coefficient was-1.24),while the achievement motivation was positively related to extraversion and openness and the pursuit of success (the correlation coefficients were 1.51 and 1.53).Conclusion There is a significant correlation between personality traits and achievement motivation.The more extroverted personality medical staffs have,the more easy-going they are,and the more the pursuit of success oriented achievement motivation they have;and the higher the neurotic tendency individuals have,the more they incline to avoid failure of achievement motivation.
