Objective: To study the characteristics of suicides treated in the emergency department of a large general hospital in China, so as to provide relevant data for preventing suicide. Methods:Study the records of 183 suicides in the emergency department of XuanWu hospital during Jan 1st to Dec 31 of 2004. Result:Among all suicide cases, young people (aged 20 to 29 years) were the most (81cases, 44.3%); Females (n=147) outnumbered males (n=36, f:m=4.1:1); 170 (92.8%) cases had ingested poisons, among them, 119 used hypnotics or pesticides. The mortality was 3.3% (6/183), that of males (3/36=8.33%) was much higher than that of females (3/147=2.04%); Most of suicides happened during 18 to 24 o'clock(71cases, 38.8%)(P

Objective To observe the clinical effect of Sarcandra glabra extracts against oxida-tive damage. Methods 46 patients diagnosed as nasopharyngeal careinoma stage Ⅲ and Ⅳ a were ran-domly divided into control group (n=25) and study group (n=21). All patients underwent combined chemoradiotherapy treatment. Besides, the patients in study group were given Sarcandra glabra 20 g/d orally. The total activity of superoxide dismutase (SOD) and plasma eontent of malonaldehyde (MDA) were measured before and after treatment. The tumor regression and aeute chemoradiotherapy side reaction were observed after treatment. Results All patients fulfilled the whole range treatment, After treatment, the total plasma SOD activity decreased and plasma MDA level was elevated in con-trol group, while both SOD aetivity and MDA level were reduced in study group (P<0. 05). When the therapy ended, the SOD of study group was higher and MDA was lower than that of control group (P<0.05). There was no difference in tumor local control rate after radiotherapy between two groups (P>0.05). The incidence rate and severity of acute chemoradiotherapy side reaction were slighter in study group than those in control group (P<0. 05). Conclusion Sarcandra glabra extracts exerts obvious inhibitory effect on oxidative damage. Combined with chemoradiotherapy, Sarcandra glabra contributes to the tumor regression of patients with stage Ⅲ and Ⅳa nasopharyngeal carcinoma and at-tenuation of chemoradiotherapy side reaction.

Aim To study the effect of IL-1β on pro-tein expression of vascular endothelial growth factor in glioma cells and plasma membrane microcapsule struc-ture protein caveolin-1 and plasma membrane vesicles in brain microvascular endothelial cells, and prelimi-narity discuss the possible mechanism of IL-1β opening blood tumor barrier. Methods The tumor barrier mod-el was established by transwell in vitro. The effect of IL-1β on the expression of VEGF in glioma cells and caveolin-1 in brain microvascular endothelial cells was dynamically monitored by Western blot. TEM was used to observe the number of plasma membrane vesicles of brain microvascular endothelial cells. Sodium fluores-cein leakage test was used to assess the permeability of blood tumor barrier after IL-1β. Results The tumor barrier model was successfully established by transwell in vitro. When IL-1β treated the model of blood tumor barrier,the expression of VEGF increased,and reached the peak at 60min,and recovered to the initial state at 120min. The permeability of the blood tumor barrier model was the highest at 60min. In addition,our re-sults also found that,the protein expression of plasma membrane microcapsule structure protein caveolin-1 and number of plasma membrane vesicles in brain mi-crocapsule endothelial cells reached peak at 60 min, subsequently reduced and returned to non drug state at 120min. Conclusion IL-1β increases blood tumor barrier permeability,which may be related to IL-1β in-creasing the number of plasma membrane vesicles through VEGF/ caveolin-1 pathway.

Objective: To compare the effects of bare-handed cardiopulmonary resuscitation (CPR) and cardiopulmonary resuscitator in emergency treatment. Methods: A total of 185 patients received CPR in our hospital from 2013-01 to 2015-10 were enrolled. The patients were divided into 2 groups: Bare-handed CPR (Bare-handed ) group, n=101 and Cardiopulmonary resuscitator (Mechanical) group, n=84;meanwhile, taking 30 min as border time, each group was further divided as short time CPR subgroup and long time CPR subgroup. High quality CPR was conducted in all patients. The success rates, time and blood levels of lactic acid after CPR were compared among short time subgroup, long time subgroup between Bare-handed group and Mechanical group respectively. Results: For short time CPR patients, the success rates, time and blood levels of lactic acid after CPR were similar between Bare-handed group and Mechanical group; for long term CPR patients, the success rates and time were similar between Bare-handed group and Mechanical group, while blood levels of lactic acid after CPR in Mechanical group (6.88 ± 1.82) mmol/L was lower than Bare-handed group (9.39 ± 2.39) mmol/L, P<0.05. Conclusion: The success rates of bare-handed CPR and mechanical CPR were similar for emergency treatment, both methods were effective; while mechanical CPR may save the manual labor, achieve better metabolic result which should be recommended in clinical practice.
