In acu-massage group, scalp-points as Dingzhongxian （顶中线 MS 5）, Ezhongxian （额中线 MS 1）, Zhensheng Zhengzhongxian （枕中正中线 MS 12）, etc, and body acupoints Taiyang （太阳 EX-HN 5）, Yintang （印堂 EX-HN 3）,Shanzhong （膻中 CV 17）, etc. acupoints were punctured, followed by performing massage frorn Yintang （EX-HN 3） to Shenting （神庭 GV 24） and to the superciliary arch and Taiyang （EX-HN 5）, etc. for 6-9 times. The treatment was conducted once daily with 10 times being a therapeutic course. In medication group, the patients were asked to take Alprazolam （0.4 mg, t. i.d. in the 1st 10 days; 0.8 rng, t. i.d. thereafter）, etc. Results： Following 3 courses of treatment, of the 58 and 30 cases in acu-massage and medication groups, 22 （37.93%） and 8 （26.67%） were cured, 18 （31.63%） and 11 （36.37%） had marked improvement in clinical symptoms, 16 （27.59%） and 4 （ 13.33% ） had improvement, 2 （3.45%） and 7 （23.33%） failed, with the total effective rates being 96.55% and 76.67% respectively. Three months after treatment, follow-up showed that of the 40 and 19 cases in acu-massage and medication groups, 2 （5.0%） and 4 （21. 1%） relapsed separately conclusion：The therapeutic effect of acupuncture combined with massage is markedly superior to that of medication in relieving neurosism.展开更多

After male Sprague-Dawley （SD） rats were treated intra-gastrically with different doses of MC-LR for 90 d, the locomotor activity, spatial learning and memory function were evaluated in the rats after treatment using open field tests and Morris water maze tests. The results show that MC-LR exposure can lead to impairment of the spatial learning capacity and locomotor activity in rats at the dose of 2. 00 p,g/kg. The levels of NAA in the hippocampus were measured by magnetic resonance spectroscopy （MRI）. A significant decrease of NAA/Cr ratio （ P 〈 0. 05） was observed in the hippocampous. This study indicates that intra-gastrical exposure to low-doses of MC-LR has adverse effects on neuronal behavior and NAA levels in the hippocampous.展开更多
