Objective To study the sedative and hypnotic effects of oil of spine date seeds by different extraction technologies(compression and supercritical CO2 extraction,OSDSE and OSDSS) in mice.Equivalence test was used to test the effects.Methods Spontaneous activity and tolerance were observed by photoelectric counting method after long-term intragastric administration of OSDSE and OSDSS in mice.The sleeping time and delitescence induced by above threshold dose of pentobarbital sodium and sleeping number induced by below threshold dose of pentobarbital sodium were utilized to observe the hypnotic effect of OSDSE and OSDSS in mice.Diazepam was applied as a positive control drug.Results OSDSE and OSDSS could obviously reduce spontaneous activity,increase sleeping time and sleeping number in mice,while the sleeping delitescence was shortened.All the effects induced by OSDSE and OSDSS were equivalent.The inhibitory effect of spontaneous activity was enhanced following repeated administration,while the effect of diazepam was reduced.Conclusion Both oils of spine date seeds can induce sedative and hypnotic effects without tolerance.They have equivalent effects on sedation and hypnosis.

Objective To study the protective action of Semen Ziziphi Spiosaeand on acute myocardial ischemia and its effecte on infarcted area. Methods Left anterior descending(LAD) of coronary artery was ligated to cause the big rat's acute myocardial ischemia, and electrocardiogram (ECG) was used to appraise the effect of sour jujube kernel total soap on the myocardial infarcted area. Results Compared with control group, the experimental group treated with sour jujube kernel total soap glucosidal showed significantly smaller infarcted area; and ECG showed the heart rhythm, S-T piece and T wave value were significantly decreased in the experimental group. Conclusion Sour jujube kernel total soap glucosidal can reduce the myocardial infarcted area caused by ligature of LAD, so as to protect the cardiac muscle.

Objective To investigate the expression of interleukin-33(IL-33)and vascular endothelial growth factor C(VEGF-C)in gastric cancer tissues and serum,and to explore the relationship between these two indicators and gastric cancer lymph node metastasis.Methods The levels of IL-33 and VEGF-C in the tissues of gastric mucosa and serum were detected by immunohistochemical SP method and enzyme-linked immunosorbent assay(ELISA)in 98 patients with gastric cancer and 36 healthy subjects.Results The expression rates of IL-33 and VEGF-C in gastric cancer were 67.35％and 74.49％,which were significantly higher than the rates in normal gastric tissue(47.22％and 61.11％).The difference was statistically significant(P<0.01).The expression of IL-33 and VEGF-C was correlated with the degree of tumor differentiation,tissue infiltration,lymph node metastasis,distant metastasis and clinical stage(P<0.05).The positive rates of IL-33 and VEGF-C in gastric cancer lymph node metastasis group were higher than those in non-lymph node metastasis group(P<0.05).The serum concentrations of IL-33 and VEGF-C in patients with gastric cancer were(50.24±13.08)pg/mL and(210.73±58.35)pg/mL,respectively,which were higher than those in healthy control group(P<0.05);the expressions of serum concentration of IL-33 and VEGF-C in the cases with lymph node metastasis were higher than those without lymph node metastasis and the difference was statistically significant(P<0.05).Conclusion High levels of IL-33 in gastric carcinoma patients might induce the secretion of VEGF-C,promote lymph node metastasis,and be applied as an important index of the appraisal to the prognosis of gastric cancer.
