Objective To study the chronic neurotoxicity of aluminum through observing the adverse effect of long term intake of aluminum on the memory of rats.Methods 40 Wistar rats were randomly divided into 4 groups and given Al2(SO4)3 through drinking water for 6 months,the concentration of Al3+ in the waters were 0.12 mg/L,40 mg/L,400 mg/L and 2 000 mg/L respectively,then passive avoidance tests were carried out.One month before pregnancy,the dams were given Al3+ of 40 mg/L and 2 000 mg/L respectively,after the offspring were born,the group given high[Al3+] was subdivided into two groups,one continuously drank the water with high [Al3+],the other drank the water without Al3+.The dams drinking water with low [Al3+] and their offspring continued to drink the same water as before.At the age of three months,all the offspring were examined with passive avoidance tests.Results The memory acquirement in all adult rats were not abnormal,but memory retention were severely damaged (P0.05).The rats continuously drinking water with high [Al3+] after birth had significant damage both in memory acquirement and in retention (P

Objective To explore the blood drug concentration monitoring of sustained-release valproate(DK)in children with epilepsy,focusing on the selection of sampling time and evaluation of the results.Methods Two hundred and seventy-one children taking DK and 155 children taking sodium valproate syrup(VPA Syr)were involved and their serum were taken when achieved steady state to determine the valproic acid level using fluorescence polarization immunoassay.They were divided into 4 groups,which were DK taken once daily group(DK qd group,126 children),DK taken once daily at night and sampled on morning group(DK qn group,26 children),DK taken every 12 h group(DK q12 h group,119 children),VPA Syr q12 h group(155 children).Determine the proportion of the blood drug concentration of each group below,ithin and above the therapeutic range for valproate(50-100 mg/L)were determined.The data were analyzed by t test.Results The Cmin of DK qd group were(73.09?19.91)mg/L,significantly lower from the serum concentration of DK qn and sampled on morning group [(94.94?25.44)mg/L](P0.05).Conclusions DK qn should sampled at night before the night dose.The Cmin of DK q12 h was higher according to the therapeutic range,it's favorable range still needs clinical practice.

ObjectiveTo investigate the expression of integrin β1 during retinal detachment and reattachment of rabbits.Methods24 rabbits were used to make retinal detachment and reattachment model by using hyaluronidase and micropipette. The expression of integrin β1 were observed with hybridization in situ.ResultsThe expression of integrin β1 in reattached retina was lower than that in detached retina.ConclusionRetinal reattachment may inhibit the development of proliferative vireoretinopathy.

The experience of "Zhenjing Anshen" acupuncture method originally created by professor WANG Fuchun for treatment of insomnia was introduced in this paper. From aspects of insomnia pathogenesis, theoretical foundation, characteristics of acupoint selection, needing methods, needing time, etc., the experience of Professor WANG Fuchun for treatment of insomnia was explained. The "Zhenjing Anshen" acupuncture method proposed, for the first time, "new three layers" method of acupoint selection, including Sishencong (EX-HN 1), Shenmen (HT 7), Sanyinjiao (SP 6). This method presents the principles of acupoint selection along meridian, acupoint selection based on essence-qi-spirit, harmony of yin and yang. The acupuncture manipulation is emphasized, and treating time (the period of the day from 3 pm to 5 pm) is focused on; acupoint selection is simple but essential, and acupoint combination is scientific, which receives notable therapeutic effect in clinic.
