BACKGROUND: Many animal and clinical studies have reported that the safe and effective usage of umbilical cord blood-derived mesenchymal stem cells (UCB-MSCs) transplantation for treatment of neurological genetic diseases.OBJECTIVE: To investigate the feasibility and effect of UCB-MSCs transplantation in the treatment of spinal muscular atrophy (SMA).METHODS: A child admitted at January 2010 had been confirmed as having SMA, and drug and rehabilitation therapies were invalid. Then, the child received UCB-MSCs transplantation via the first intravenous infusion and three times of subarachnoid injection, once a week, (4-6)×107 cells once and four times as a course. Neurological physical examination, biochemical test, muscle enzymes detection, FIM scoring and electromyography (EMG) examination were conducted. RESULTS AND CONCLUSION: Compared with prior to transplantation, the level of muscle enzymes decreased, FIM scores were increased from 68 to 93 points, EMG results showed that the motor units with re-contraction in each 10.0 ms were increased that the motor function was improved, the lower extremity muscle strength elevated, and the self-care ability was improved in the SMA child at 6 months after transplantation. During the 10-month follow-up, the child had no adverse effects. It is indicated that UCB-MSCs transplantation is effective to treat SMA, and the neurological function has a remarkable restoration.

Objective: To provide references for quality evaluation of Lonicerea Japonicae Flos (LJF) through exploring correlation between color and contents of active ingredients of LJF in different development periods. Methods: The colorimeter was used to measure the color of LJF in different development periods; HPLC was applied to determine the contents of phenolic acids, flavonoids and iridoids. SPSS 17.0 software was used to analyze the correlation between color and chemical composition of LJF. Results: With the development of flower buds, the contents of phenolic acids, flavonoids compounds achieved the highest in two white stages and the contents of iridoids came to the highest in big white stage and silver flower stage. Therefore, only taking the consideration of the content of active ingredient, the best harvest time of LJF might be the big white stage. There was a significant positive correlation among contents of phenolic acids, flavonoids and brightness (L*) of LJF in different development periods, and there was a very significant negative correlation among contents of phenolic acids, flavonoids, iridoids, and browning index (BI). Conclusion: The color of LJF is closely related to the content of active ingredients, L* and BI can better link appearance and inner quality of LJF.
