Simulation teaching is helpful to learn general principles of solving complex problems,making decisions,resource management and teamwork behaviors during clinical treatment in order to prevent,ameliorate and resolve critical incidents and crisis situations.The medical staff will improve their medical,cognitive and social skills in the recognition and treatment of realistic and complex medical situation.

Objective:To investigate variety pattern of expression level of TCRV?subfamilies in mononuclear cell in spleen tissue of rats with dampness pathogenic factors and normal rats by using FQ-PCR technique. Methods:32 SD rats were divided into four groups: normal group, external dampness group, internal dampness group, external and internal dampness group. Observing period was 20 days. 3 Rats were randomly selected from each group in order to exam the TCRV? subfamilies expression level. Results:The expression of TCRV?1, TCRV?7, TCRV?9 and TCRV?13 in external dampness group were higher than those in normal group (P

Objective To analyze the clinical characteristics and the outcome of severe trauma of various ages in emergency department,to improve the therapeutic effect of emergency rescuing.Methods Two thousand and sixty nine patients of severe trauma were treated during a seven-year period from October 1997 to October 2004.The studied patients were divided into 5 groups:(1)adolescent group(Group A,＜13 years old,n=106);(2)juvenile group(Group B, 13-18 years old,n=128);(3)youth group(Group C,18-40 years old,n=1518);(4)middle age group(Group D, 40-60 years old,n=215);and(5)elderly group(Group E,＞60 years old,n=102).All the patients were evaluated with Injury Severity Score(ISS),and the result was≥16 in all of the studied patients.Results The incidence of severe trauma in male in all 5 groups was higher than that in female,and it was significantly higher in Group C,Group D and Group E when compared with that in the other groups(P＜0.01).Traffic accident was the leading cause of injury,and its incidence in Group A,Group B and Group D was higher than that in other groups(P＜0.01).However,injury caused by falling from high places was the second cause of injury,being significantly increased in Group A,while armed fighting and injury during work being significantly increased in Group B,Group C and Group D,slip fall injury being significantly increased in Group E(P＜0.01).Head injury was mainly found in Group A and Group E,extremities injury and/or spinal injury were increased markedly in Group B,Group C and Group D(P＜0.05),abdominal injury was significantly decreased in Group E(P＜0.001).The total mortality was 11.9%(246/2069).The mortality within 24 hours (20.6%,21/102)was significantly higher than that beyond 24 hours(7.8%,8/102)in Group E(P＜0.01).The time of staying in the emergency department differed significantly between the survived patients and those died in all 5 groups (P＜0.01).Conclusion The gender,the incidence and the characteristics of the injury causes and injury sites differed between severely injured patients of various ages.Mortality in the elderly is significantly increased following severe trauma. The idea of“golden one hour”and“platinum ten minutes”,measures of shortening the time of staying in the emergency clinic,early definite operation and damage control operation should be emphasized.

Objective To determine if pregnancy affects the toxicity of bupivacaine and to investigate the effect of Shenfu injectio,a preparation of Chinese herbal medicine,on central nervous system and cardiac toxicity of bupivacaine in pregnant rats.Methods Twenty-four SD rats weighing 320-360 g were assigned to 3 groups(n =8 each):Ⅰ non-pregnant control group,Ⅱ pregnant control group and Ⅲ Shenfu injectio pretreatment group. The animals were anesthetized with isoflorane(2%-4%)-O_2 inhalation which was stopped before bupivacaine infusion was started.Femoral artery was canunlated for MAP monitoring and blood sampling and femoral vein was cannulated for bupivacaine infusion.MAP,HR and ECG were continuously monitored.All animals in the 3 groups received continuous infusion of 5% bupivacaine at 2 mg?kg~(-1).min~(-1).In group Ⅲ Shenfu injectio 10 ml?kg~(-1) was injected intraperitoneally(IP)30 min before bupivacaine infusion whereas in the two control groups(group Ⅰ and Ⅱ)equal volume of normal saline was injected IP instead of Shenfu injectio.The duration between the beginning of bupivacaine infusion and onset of convulsion/arrhythmia(QRS≥90 ms)/asystol was recorded and the amount of bupivacaine infused was calculated.Results There was no significant difference in the amount of bupivacaine causing convulsion and asystol between group Ⅰ and Ⅱ but the amount of bupivacaine causing arrhythmia was significantly larger in group Ⅰ(non-pregnant) than in group Ⅱ(pregnant control group)(P＜0.05).The amount of bupivacaine causing convulsion,arrhythmia and asystole was significantly larger in Shenfu injectio pretreatment group(group Ⅲ)than in pregnant control group(group Ⅱ)(P＜0.05 or 0.01).Conclusion Bupivacaine- induced cardiotoxicity is increased in pregnant rats and Shenfu injectio pretreatment can reduce the systemic toxicity of bupivacaine in pregnant rats.

OBJECTIVETo compare the differences in the clinical function and lumbar and abdominal myodynamia in patiants of lumbar disc herniation treated with moxibustion at Dazhui (GV 14) and Guanyuan (CV 4) and acupuncture.

METHODSForty cases were randomized into a moxibustion group and an acupuncture group, 20 cases in each group. In the moxibustion group, the warm moxibustion was applied alternatively at Dazhui (GV 14) and Guanyuan (CV 4) once every other day, 1 h each time, once every day. In the acupuncture group, acupuncture was applied to the corresponding acupoints based on the affected lumbar vertebras, such as Jiaji (EX-B 2), Shens-hu (BL 23), Dachangshu (BL 25) and Huantiao (GB 30), etc. , once evey day 30 min each time. The treatment for 3 weeks was taken as one session in each group. Totally, one session treatment was required. Surface electromyography (SEMG) of bilateral paraspinal muscle and rectus muscle, and JOA score of low back pain were observed in the two groups.

RESULTS(1) JOA score: the score of subjective symptoms, score of activity of daily living (ADL) and total score were improved obviously as compared with those before treatment in the two groups (P<0.01, P<0.05). The results of subjective symptoms score, score of ADL and total score in the acupuncture group were superior to those in the moxibustion group after treatment (6.95+/-0.94 vs 5.50 +/-0.89,10. 90+/-1.86 vs 8.90+/- 1. 92,22.50 +/- 2.82 vs 19.35 +/- 2. 70, all P<0. 05). (2) SEMG comparison: root-mean-square value (RMS) was all reduced in SEMG of the anteflexion, rear protraction, orthostatism, bilateral bending and neck and leg rear flexion for strengthening lumbar muscle as compared with those before treatment in the two groups (P< 0.05, P<0. 01). RMS of the anteflexion and bilateral bending in the acupunture group were reduced much obviously as compared with the moxibustion group. In terms of sitting position anteflexion, rear protraction, orthostatism, bilateral bending and neck and leg rear flexion for strengthening lumbar muscle, median frequency (MF) after treatment was all improved as compared with that before treatment in the two groups (P<0. 05, P<0. 01). In terms of anteflexion, the electrode MF after treatment was improved much obviously in the acupuncture group(P<0. 05).

CONCLUSIONMoxibustion at Dazhui (GV 14) and Guanyuan (CV 4) and conventional acupuncture all improve muscle function, relieve muscle fatigue, increase the ability of anti-muscle fatigue, strengthen lumbar vertebral stability, release subjective symptoms and improve ADL. But, the effects of moxibustion are slightly lower than those of acupuncture.
