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.

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 investigate the stability of cefoselis sulfate for injection in xylitol injection.METHODS:The mixture of cefoselis sulfate for injection and xylitol injection was observed within 6 h after mixing were observed at 25℃ and 37℃ with regard to its appearance,pH value,and UV spectra of cefoselis.The content of cefoselis sulfate in the mixture was determined by UV spectrophotometry.RESULTS:No marked change was noted for the mixture within 6 hours after mixing in terms of the appearance,pH value,ultraviolet absorption spectra and content.CONCLUSION:Cefoselis sulsate for injection is stable within 6 hours after mixing with xylitol injection.

Objective:To investigate the changes and significances of serum cystatin C and transforming growth factor-β1 levels for the neonatal asphyxia.Methods:Forty-six asphyxia newborns were chosen as the asphyxia group,and thirty healthy newborns were selected as the control group.The TGF-β1,CysC,BUN,Scr,and GFR levels of both groups were detected on the 1st,3rd,7th day after hospitalization.According to the renal injury,the 46 newborns were divided into normal group and asphyxia group,and the serum indexes were detected and analyzed.Results:On the 1st,3rd,7th day after hospitalization,the TGF-β1,GFR of asphyxia group was obviously increased and was lower than those of the control group (P＜0.05);the level of CysC,BUN,Scr in both groups were decreased,and the change degree in asphyxia group were higher than that of the control group (P＜0.05);the CysC,BUN,Scr in renal injured group were higher than those of normal group,and TGF-β1,GFR were much lower (P＜0.05).Additionally,TGF-β1 level of renal injured group was negatively correlated to the BUN and Scr,and positively correlated with the GFR (P＜0.05).The level of serum CysC in renal injured group was positively correlated to BUN and Scr and negatively correlated to GFR (P＜0.05).Conclusion:The serum TGF-β1,CysC in asphyxia newborns had significant changes compared with the healthy newborns and was correlated to the renal injured indexes,which had clinical directive significance on the early diagnosis,condition judgment,and prognosis of neonatal asphyxia with renal injury.

Objective The aim of this study was to analyse characteristics of CRC in a cohort under the age of 40 .Methods Using single center retrospective cohort study ,we reviewed the prospectively collected database of 2 897 colorectal cancer patients who had undergone curative CRC resections in Chongqing Medical University between 2010 and 2014 .175 patients (5 .8% ) were under 40 ,in which six patients for various reasons (including recurrent colorectal cancer hospital ,incomplete information ,etc .) were excluded .A group of 180 consecutive patients over the age of 40 undergoing surgery for colorectal cancer in the same centre was used as control .Results There had no difference in tumor classification and tumor location between the younger group (<40) and the older group(>40) ,but the lymph node positive rate in younger group was higher ,unable to accurately grasp the preopera‐tive lymph node status ,lead to lack of preoperative staging ,and that made it difficult to preoperative treatment options .Conclusion Therefore ,to young people in colorectal preoperative neoadjuvant chemoradiation indications and the assurance of intraoperative re‐section range ,we need to do more consideration.

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.
