Clinical practice is an important step in medical education. However,its effect is now becoming worse and worse because of the influence of employment difficulties,post-grad-uate entrance exam and medical environment. It is hard to resolve these problems by simply education method. These problems are very common in management and can be found in prejob training,employee loyalty and quality management,respectively. It is a new approach to improve clinical practice education by enhancing teachers'management ability.

Lipid emulsion has been used not only as nutrition in clinic practice,but also recently as an adjuvant therapy of lipophilic drugs poisioning,which is most likely to cause cardiopulmonary arrest and brings difficulty to conventional treatments.More and more reports of whether studies in labs or clinic cases suggest that lipid emulsion can be adopted as one of therapies for lipophilic drugs poisioning.The article mainly sums up the development of lipid emulsion remedy against lipophilic drugs poisioning in the hope of providing reference for clinical application of lipid emulsion to detoxification.

Objective To explore the characteristics of P300 of subjects with attention deficit/hyperactive disorder(ADHD).Methods 34 children with ADHD were selected as ADHD group and 32 healthy subjects were selected as the health control group.They were matched in age,gender,degree of education.The auditory Oddball paradigm was applied,the event-related long latency components (N2 and P3) from Cz and Pz were measured in each test.Results Compared with the health control group,at the Cz electrode,children with ADHD showed a significandy prolonged latency of target N2 [(277.2 ± 20.3) ms vs (259.0 ± 14.9) ms,t =3.70,P ＜ 0.01] and decreased amplitude of target P3[(4.1 ± 1.6) μμV vs (5.7 ±2.0) μμV,t =3.57,P＜ 0.01].At the Pz electrode,the patient showed a significantly prolonged latency [(342.4 ± 26.3) ms vs (324.6 ± 15.5) ms,t =3.33,P ＜ 0.01] and decreased amplitude of target P3 [(4.1 ± 1.9) μV vs (7.4 ± 2.2) μV,t =6.54,P ＜ 0.01],decreased amplitude of non-target P2 [(3.0±1.l)μμV vs (3.7 ±1.3) μV,t =2.30,P＜0.05].Conclusion This study provides direct evidence that ADHD subjects have abnormal indices of endogenous P300,which is suggested that P300 might be potentially objective indicator applied in evaluation of cognitive dysfunction in ADHD children.

BACKGROUND: At present, there are many drugs and therapeutic methods for dementia at home and abroad. Both xingding and piracetam are the kind of improver for circulatory obstruction and protector for nerve cells and can slow down the functional decline of brain tissue and provide improvement for cognitive deficit.OBJECTIVE: To observe the improvement of allied application of xingding and piracetam on cognitive function in treatment of vascular dementia.DESIGNS: Case-controlled study based on patients.SETTING: Neurological Department in Affiliated Hospital of Henan University. PARTICIPANTS: Totally 91 cases of vascular dementia hospitalized in Neurological Department of First Affiliated Hospital of Henan University from October 2000 to March 2002, which were randomized into treatment group of 48 cases and the control of 43 cases.INTERVENTIONS: In treatment group, xingding injection of 20 mL and piracetam of 8 g were administrated and 50 g/L glucose injection 250 mL was added respectively for intravenous injection, once daily and 14 days made one session. In the control, piracetam of 8 g was prescribed with 50 g/L glucose injection 250 mL added for intravenous injection, once daily and 14 days made one session. There was no any difference in other medication treatment. One month later after treatment of two groups, he patients were re-examined with mini-mental state examination(MMSE) and Hasegawa dementia scale(HDS) was used to assess the cogitative improvement and neurological defect scale(NDF) was used to analysis the improvement of neurological functional symptoms.MAIN OUTCOME MEASURES: ① Scores of MMSE, HDS and NDF in two groups. ② Analysis on therapeutic effects.RESULTS: Totally 91 cases entered the analysis on the results. There was no significant difference in MMSE and HDS before treatment in two groups. In treatment group, after treatment, MMSE and HDS scores were (23.26±5.12) and(2.78±3.46) respectively, indicating significant difference(t=4.79, 15.44, P＜0.01) compared with the control(19.14 ±3.21)and(15.21±2.29) . NDF score was 13.68±7.83 after treatment and the significant difference was presented compared with the control(17.33 ±8.81) . The total effective rate(total remarkable rate + progression) was 92% in the treatment group and was 56% in the control. By the comparison between two groups, the difference was significant(χ2= 15.48, P＜0.01).CONCLUSION: After treatment, MMSE score in treatment group was higher than that in the control and HDS score was lower than that in the control, explaining that xingding allied piracetam significantly improves cogitative function in the treatment of vascular dementia.

Objective To investigate effects of three kinds of neutral,happy,sad emotional faces stimulus on sustained attention task using N170 in depression patients to analysis the correlation of depression in patients with depression,anxiety severity and the amplitude and latency of N170.Methods Twenty-eight patients with depression aged from 22 to 69 years (case group),and 31 healthy controls (control group) aged from 20 to 61 years were recruited for the study.Subjects were asked to perform tasks in the selection of attention following randomly presented three kinds of happy,neutral and sad emotional faces stimuli.Brain auditory evoked potential including N170 amplitude and latency were recorded during the tasks.HAMD and HAMA were used to assess the severity of depression and anxiety.Results There was significant difference between case group and control group in N170 latency by three kinds of happy,neutral and sad emotional faces stimulation in the local skull (T5,T6,O1,O2) (P＜0.05).But the difference was not significant in N170 amplitude (P＞0.05).The total score of HAMD in case group had a positive correlation with N170 amplitude by neutral facial emotion stimulation in part of T5 (r=0.443,P=0.018).Conclusion There is significant change in the initial cognitive processing of different emotional faces in the patients with depression.And the severity of depression is related to the N170 amplitude induced by the neutral emotional faces stimulation in some parts of brain.
