Death education that began in the western countries,starting with the rise of thanatolography,is the important content of modern education which can not be ignored.This paper summarized the definition,content,subjects and course of death education by reviewing the literatures,aiming to provide some reference for the death education at present in our country.

0.05). 73.96% of eczema were taken place at the age of 1～6 months, 13.02% were at the age of 6 months to 2 years, and 13.61% were at the age of 2～3 years. The incidence of eczema is also relevant to feeding patterns, which is 62.23%, 23.08% and 14.79% respectively by breast-feeding, mixed feeding and artificial feeding. Some other factors that relevant to the onset of eczema also have been found in the study, such as constitution, weather, genetic background, and so on. Conclusion Feeding pattern, genetic background and some other factors were relevant to the onset of eczema.

This study was aimed to explore the clinical efficacy of Shen-Kang Injection (SKI) combined with hemodialysis in the treatment of chronic renal failure (CRF) patients. A total of 41 end-stage CRF patients under the hemodialysis treatment were randomly divided into the SKI treatment group of 19 cases and a control group of 22 cases. Both groups were treated with standard dialysis and the hemodialysis was maintained in the same symp-tomatic treatment conditions. Patients in the control group underwent three hemodialysis treatments in one week, while those in the treatment group were given hemodialysis twice a week based on the symptomatic treatment. And SKI was given after each time of hemodialysis in the treatment group. Indexes and changes in serum creati-nine (Scr), blood urea nitrogen (BUN) level, dialysis adequacy, nutrition status, traditional Chinese medicine ( TCM ) syndrome and other aspects of both groups were observed . The results showed that in the treatment group and control group, there were no significant differences in the renal function, dialysis adequacy, nutrition indica-tors and electrolyte ( P > 0 . 05 ) . In the treatment group , the total efficiency of TCM syndrome was 84 . 21%. And the total efficiency of TCM syndrome in the control group was 45.45%. The treatment group was better than the control group (P < 0.05). Symptoms such as scaly dry skin, numbness of the four limbs and dry stool were not obviously improved . And there was no statistical significance ( P > 0 . 05 ) . Symptoms such as fatigue , shortness of breath, poor appetite, dizziness, headache, lower back pain and spontaneous sweating were improved significantly. And there was statistical significance ( P < 0 . 05 ) . The treatment group was better than the control group . There were no abnormalities in the routine tests of blood, urine and stool, electrocardiogram, liver function, renal func-tion and electrolyte. In the treatment group, there was no significant adverse reactions during patients received SKI. The SKI has good safety. It was concluded that SKI combined with hemodialysis in the treatment of CRF is able to improve the clinical symptoms of patients and improve the patients' quality of life. When patient received adequate dialysis, SKI may reduce the dialysis frequency per week.

Objective To study the clinical effects of low dose mifepristone together with methyltestosterone on the treatment of climacteric dysfunctional uterine bleeding(DUB).Methods Seventy patients with DUB were underwent dilatation and curettage of the uterus and divided into treatment group(n=35) and control group(n=35).The patients in the treatment group were treated with mifepristone and methyltestosterone,and those of the control group were treated with norlutin.The amenorrhea,the changes of endocrine and the pathology of endometrium were observed.Results All the patients were amenorrhea during the period of taking medicine and the regular menses was recovered after the treatment.Eight patients were menopause after the treatment.The levels of FSH,LH and P were decreased.The endometrium were atrophied and the anemia was improved.Conclusion Low dosage of mifepristone with methyltestosterone can prevent endometrial hyperplasis and it is safe and effective for the treatment of climacteric dysfunctional uterine bleeding.

OBJECTIVE:To investigate the effects of different elutions of Hyssopus cuspidatus on smooth muscle contraction of isolated tracheal in Guinea pigs. METHODS:Isolated tracheal rings were prepared and soaked in Krebs-Henseleit,using acetyl-choline(ACh,1×10-7 g/mL)or histamine(His,1×10-6 g/mL)to induce contraction of tracheal rings,then the effects of H. cuspi-datus water elution and 30%,50%,60%,70%,95%ethanol elutions with mass concentrations of 0.08,0.16,0.32,0.64,1.28, 2.56 mg/mL on contraction of tracheal rings were respectively investigated. Contraction curves were recorded and antispasmodic rates were calculated. Tests were treated with saline as blank control and aminophylline (0.08 mg/mL) as positive control. RE-SULTS:Compared with blank control,0.16-2.56 mg/mL 30%,50% ethanol elution,0.32-2.56 mg/mL 60% ethanol elution and 0.64-2.56 mg/mL 70%,95% ethanol elution can obviously inhibit ACh-induced contraction of tracheal rings,antispasmodic rates were obviously increased(P<0.05 or P<0.01);0.32-2.56 mg/mL water elution and 30%,50% ethanol elution,0.16-2.56 mg/mL 60%,70% ethanol elution and 1.28-2.56 mg/mL 95% ethanol elution can obviously inhibit His-induced contraction of tracheal rings,antispasmodic rates were obviously increased (P<0.05 or P<0.01). The effects of 2.56 mg/mL 60% ethanol elution ap-proach to aminophylline. CONCLUSIONS:Different elutions of H. cuspidatus has certain antagonistic effect on the ACh-induced or His-induced smooth muscle contraction of isolated tracheal in Guinea pigs;60% ethanol elution shows the strongest effect, which has similar effects with aminophylline at high mass concentration.

each group were sacrificed, respectively. Distributions of BrdU positive cels and ChAT positive cels were detected by S-P immunohistochemical method. The learning and memory abilities of rats were detected by Morris water maze system.
RESULTS AND CONCLUSION:BrdU positive cels were mainly distributed in the cortex and hippocampus, especialy around the blood vessels, and there was the presence of focal aggregation. A smal amount of BrdU positive cels were observed in the basal ganglia and thalamus as wel as in the ependyma. BrdU positive cels were counted at different time after operation. The number of BrdU positive cels decreased with time, and only a smal number of BrdU positive cels were observed at 60 days after transplantation. The number of ChAT positive cels at different time after transplantation was ranked as folows: neural stem cel transplantation group > model group > sham operated group (P < 0.05). Compared with the model group, the time for searching the platform was significantly lower in the neural stem transplantation group and sham operated group, but the number of crossing the platform was significantly higher in the neural stem cel transplantation group and sham operated group (P < 0.05). The results show that neural stem cels could be transplanted into the rats with vascular dementia, and the cels could survive and migrate in the brain of rats and significantly improve the learning and memory ability. This mechanism may be related to the differentiation and growth of cholinergic neurons in the hippocampus.
