Aim To investigate the effects and signifi-cance of 5-HT2A receptor antagonist MDL1 1 939 on a-mice.Methods Kunming male mice were suffered a-cute acetic acid visceral pain,acute incision pain and CCI neuropathic pain.After each animal model was es-tablished,MDL1 1 939 was injected intraperitoneally. The writhing reaction was used to assess acute acetic acid visceral pain,while the thermal withdrawal laten-cy (TWL)was used to evaluate the acute incision pain and CCI neuropathic pain.Results Compared with the control group,MDL1 1 939 (0.25,0.5,1 .0 mg· kg -1 ,i.p.)relieved acetic acid visceral pain signifi-cantly in a dose-dependent manner in mice,as re-vealed by the significant reduction of the number of twisting.In acute incision pain and CCI neuropathic pain,MDL1 1 939 (0.5 mg·kg -1 ,i.p.)significantly increased TWL level.Conclusion 5-HT2A receptor antagonist MDL1 1 939 has analgesic effects on visceral pain,acute pain and neuropathic pain,which might be a novel therapeutic target to treat different pain in clini-cal situations.

For treatment of pediatric inguinal hernia, we fabricated a device, i.e. so called "filling type pediatric hernia sac", which treats the problem from the abdominal cavity, through the abdominal and is a self-adaptive closer, using synthetic material. The device includes filling rack, self-adaptive umbrella support bar, bottom piece, outside pulling line and device fixing lines. The filling rack is composed of 2 concentric circles of 3.0 cm diameter with peripherally fixed together and can be pulled into the shapes of a ball or an olive. The supporting bar is structured of 3 pieces with 0.5 cm wide, 4.0 cm long, cross-fixed on top of the filling rack. The bottom piece is in a circular structure with a diameter of 3.0 cm, and it is connected to the filling rack bottom. Adjust positioning stay outside the fixed on the top of the device are connected at one end, and the other end free through filling the top frame connected with the bottom slice of central fixation. By using this device, we treated 37 pediatric inguinal hernia cases with 38 side-inguinal hernia successfully. The mean duration of post-operation follow-ups was 14.6 ± 5.89 months, without hernia recurrence, obvious scar and hard sections of inguinal region. This device could provide a convenient, safe and effective plugging technology for children's pediatric hernia.

To retrospectively analyze the clinical data of 42 patients at our department with bulbar myasthenia gravis.They underwent video-assisted thoracoscopic extended thymectomy (VATET) from May 2003 to August 2010.Another 42 patients treated with medications alone were selected as controls.Compared with the control group (4.32 ± 0.23),postoperative dysphagia scores improved significantly in patients undergoing VATET(9.21 ±0.41).And so did the dysphagia assessment classification (P ＜0.05).Thus VATET could effectively and definitely relieve dysphagia in patients with bulbar myasthenia gravis.

Objective To explore the relationship between vascular lesions and benign paroxysmal positional vertigo in the elderly.Methods 74 patients aged 60 years and over with benign paroxysmal positional vertigo in Huanhu Hospital and 80 subjects without vertigo history in the medical examination center of the same hospital were randomly divided into the case group and the control group,respectively.The carotid intima-media thickness (CIMT) and plaque in the carotid artery were detected using high-resolution color duplex ultrasound for evaluating large vascular lesions.At the same time,T1WI,T2WI and diffusion weighted imaging (DWI) were performed with high-field 3.0 T MRI scanner as the detection index of small vascular lesions to compare the difference in severity of lacunar infarction,leukoaraiosis and micro hemorrhage between the two groups.Both indexes were used together to compare the overall difference in the intracranial and extracranial vascular lesions between the two groups.Results Between the case group and the control group,there were significant differences in the CIMT [(0.96±0.21) mm vs.(0.84±0.26) mm,t=3.136,P＜0.05],the detection rate of plaque (89.2％ vs.72.5％,x2 =5.803,P＜0.05),the number of lacunar infarction [(3.48± 1.67) vs.(2.34± 2.06),t=1.994,P＜0.05] and the score of white matter [(4.77±2.15) vs.(3.95±2.04),t=2.430,P＜0.05].There was no significant difference in the positive detection rate of the cerebral microbleeds in the case group and control group (22.9％ vs.17.5％,x2=0.4264,P＞0.05).Conclusions There is a relationship between the benign paroxysmal positional vertigo and intracranial or extracranial vascular lesions in the elderly.Vascular factor may play an important role in the pathogenesis of benign paroxysmal positional vertigo.Not only the atherosclerosis of large and small arteries but also the microcirculation disturbance may be partly attributed to the benign paroxysmal positional vertigo in the elderly.

OBJECTIVE:To analyze the medico-ethical problems of epilepsy from Medi-ethics and its effect on improving the quality of life of the persons with epilepsy.DATA SOURCES:Articles were computer-searched from Chinese Journal of Medico-ethics, Chinese Journal of Clinical Neurology, Chinese Medical Journal, Chinese Journal of NeuroMed, Chinese Journal of Nerval Mental Disorder from January 1989 to December 2004 with the key words of "epilepsy, medico-ethics and social discrimination". And the language was restricted to Chinese. And we also selected two books, which were Bioethics written by Shen Ming-xian, and The Prevention and Therapy of Epilepsy written by Zhou Zheng-xin for reference.STUDY SELECTION: From all the preliminarily screened papers, 98 papers were obtained related to epidemiology, sociology and ethics.DATA EXTRACTION: Repeated and similar papers were excluded. 10 papers and books were selected from the 98 papers, which touched upon the problems of the epileptics and their life quality. The 10 papers have involved many cross discipline subjects, such as Bioethics, Medico-ethics,and Socio-ethics, which provided more concern about the epileptics from multiple directions.DATA SYNTHESIS: Ethics indicate the principles and guidelines for relationships between people. The ethics explored here refer to normative ethics. Generally, the basic ethical principles are: respect, beneficialness,balance and justice. Since some epileptic patients lack in the knowledge of epilepsy and proper treatment and suffer from discrimination in the health care, more untreated and non-proper treatment, doctors and nursing persons should take the attitude of being beneficial to the patients. Medication for the epileptics, especially the female patients at the first period of pregnancy, the incidence of the deformed children was high. Should the principle of beneficence be applied to mothers or children? The number of the operative treatment was more and more in patients with epilepsy, while surgery itself is a risk behavior .If there is no better method to choose, and all the available choices have their advantage and disadvantages. Physicians can only choose the better one from the two kinds of harm, trying to make the patientssuffer the least harm with the largest effect. Aggressive behaviors can be observed during seizure or unconsciousness state. Controlling the moving range of the patients with epilepsy consciously is in accord with the general ethical behavior, on the contrary, confinement disobeys the morals and the curative effect is not good. The extreme behavior of the patients with epilepsy is suicide and occurred more in unemployed, unmarried and living alone, male, and patients with mental disorders in epilepsy. The direct reasons of suicide are unemployment, low social status, and little understanding and care from their communities, families and friends.The sensible ethical principle for epileptics is to treat the patients as normal people in the society.CONCLUSION: Epileptic crowd need care from the society, family and other factors. Proper considering ethical principle in treating the population is the humane solicitude and to help the patients regain health and improve the life quality.
