RÉSUMÉ
Objective To investigate the effects of acupoint injection of mouse nerve growth factor (mNGF) on treatment of children with autistic spectrum disorders in different age groups. Methods Totally 80 cases of children with autistic spectrum disorders were divided into control group and experiment group according to random number table method, with 40 cases in each group. The control group was given structured education, ABA behavioral training, sensory integration training, and language training, 30 min for each class, 4 h each day, 5 d a week, for 5 months. At the same time, the control group was also given head needling treatment, once every other day, 3 times a week, 30 times as one treatment course, 2 courses. On the basis of the treatment of the control group, experiment group was given mNGF through acupoint injection, once every other day, 3 times a week, 10 times as one treatment course, 10 d between each treatment course, 5 courses in total. The scores of autism behavior checklist (ABC), children autism and related developmental disorders psychological education rating scale-Chinese version (C-PEP), neuropsychological development scale among children aged 0–6 years in the two groups were compared. Results Compared with before treatment, ABC scores in both group after treatment decreased significantly (P<0.05); ABC scores after treatment in children aged 18–36 months and 37–54 months in the experiment group were lower than those of the control group (P<0.05). Neuropsychological development scale scores in children aged 18–36 months and 37–54 months were better than the control group (P<0.05). Compared with before treatment, C-PEP scores of both groups increased significantly (P<0.05). There was statistical difference in the C-PEP scores in children aged 18–36 months between the two groups after treatment (P<0.05). The C-PEP scores in children aged 18–36 months increased to the highest (P<0.05).Conclusion Acupoint injection of mNGF can improve the clinical symptoms and intelligence of ASD children of all ages, but children can receive better treatment effects at younger ages.
RÉSUMÉ
<p><b>OBJECTIVE</b>To study the effects of methyl jasmonate (MJ) on the accumulation and release of main secondary metabolites i. e. scopolamine and hyoscyamine in liquid cultures of Datura stramonium hairy roots.</p><p><b>METHOD</b>After 18 days liquid culture of D. stramonium hairy roots induced by agrobacterium rhizogenes C58C1, the chemical elicitor methyl jasmonate was added into 1/2 MS liquid cultures and scopolamine and hyoscyamine on the day 0, 3, 6, 9 and 12, after dealing with MJ, was determined by HPLC.</p><p><b>RESULT</b>After dealing with MJ on the day 3, 6, 9 and 12,the concentration of scopolamine reached to 0.419, 0.439, 0.431, 0.374 mg x g(-1), respectively, the increase of scopolamine were 1.36, 1.42, 1.17 and 1.12 fold higher than that of the control, respectively. And hyoscyamine reached 1.493, 0.817, 0.723 and 0.698 mg x g(-1), respectively, the increase of hyoscyamine were 2.28, 1.11, 0.63 and 0.70 fold higher than that of the control, respectively.</p><p><b>CONCLUSION</b>MJ could stimulate the accumulation of scopolamine and hyoscyamine (3,6 d) in D. stramonium hairy root and have released them into the culture medium.</p>

<p><b>OBJECTIVE</b>To establish the hair roots culture system of Datura metel and study the hair roots growth and biosynthesis of scopolamine and hyoscyamine in hair roots culturing system.</p><p><b>METHOD</b>Direct degermed cotyledon of wild D. metel was infected by Agrobacterium tumefaciens strain C58C1 to obtain hair roots. Growth curves and scopolamine and hyoscyamine biosynthesis curves were determined. The scopolamine and hyoscyamine from different hair roots lines were examined by HPLC.</p><p><b>RESULT</b>Hair roots induction rate reached 70%. After 25 days cultured in 1/2 MS liquid nutrient medium, the hair roots weight, content of scopolamine and hyoscyamine reached maximum, tow high efficient accumulation hyoscyamine and scopolamine hair roots lines M1 and M2 were obtained. The medial accumulation coefficient of hyoscyamine and scopolamine were 2.53 times and 5.37 times compared with the leaves of wild D. metel respectively.</p><p><b>CONCLUSION</b>The established hair roots induction and culture system of D. metel provided a foundation for further obtaining scopolamine and hyoscyamine.</p>
