The extracting technology of salidroside, tyrosol, crenulatin and gallic acid from Rhodiolae Crenulatae Radix et Rhizoma was optimized. With extraction rate of salidroside, tyrosol, crenulatin and gallic acid as indexes, orthogonal test was used to evaluate effect of 4 factors on extracting technology, including concentration of solvent, the dosage of solvent, duration of extraction, and frequency of extraction. The results showed that, the best extracting technology was to extract in 70% alcohol with 8 times the weight of herbal medicine for 2 times, with 3 hours once. High extraction rate of salidroside, tyrosol, crenulatin and gallic acid were obtained with the present technology. The extracting technology was stable and feasible with high extraction rate of four compounds from Rhodiolae Crenulatae Radix et Rhizoma, it was suitable for industrial production.

To develop a LC-MS/MS method for the determination of five kinds of trace ginkgolic acids in diterpene ginkgolides meglumine injection materials, the column was Agilent ZORBAX Eclipse plus C18 (3.0 mm x 50 mm, 1.8 µm), and the mobile phase consisted of methanol-water (containing 0.2% formic acid) (95:5) at a flow rate of 0.5 mL · min(-1). The multiple reaction ion monitoring (MRM) with an ESI interface in the negative ion mode was selected. The results showed that the linear ranges of five kinds of ginkgolic acids were in the range of 0.2-36.0 µg · L(-1) (r ≥ 0.999 5). The lowest limit of quantification (LOQ) of ginkgo acid C13: 0, C15:1, C17:2, C15:0 and C17:1 were 0.18, 0.18, 0.21, 0.10 and 0.20 µg · L(-1), respectively. The average recovery was between 73.28% and 87.56%, and the average content of total ginkgolic acids in three batches of samples was in the range of 0.023-0.028 µg · g(-1), which was much lower than 2 µg · g(-1) prescribed in drug registration standards. This method is simple and rapid with high sensitivity, which can be used for the determination of five kinds of trace ginkgolic acids in diterpene ginkgolides meglumine injection materials.

AIM:To discuss Daidzein intravitreal injection whether has protective and recovery effects on acute nerve damages.
METHODS:After the crush models of acute optic nerve were set up, 72 males SD rats were divided into 4 groups randomly as common group without surgery, FBS negative control group, Daidzein treatment group ( 10μmol/L, 100μmol/L, 1000μmol/L ) and positive control group using rats nerve growth factor ( mNGF, 100ng/mL ). Three days after interference, all experimental animals were executed. HE staining was used to evaluate morphologic change of the retina, immunohisochemical staining and western-blot tests for identifying and quantifying the distinct expression of Caspase-3 and GAP-43 among the groups.
RESULTS: Compared with the normal group and negative control group, retinal morphology of different concentrations of each Daidzein treatment group and positive control group was more complete, the expression of Caspase-3 protein was relatively lower, the expression of GAP-43 protein was relatively higher, the differences have statistically significance (P<0. 05).CONCLUSION: Daizein injection in the vitreous cavity has the capacity of protection and restoration in rat's acute nerve damages.

Objective To investigate the levels of interleukin-15(IL-15) in children with acute leukemia and contribute to understand their function on acute leukemia about the process.Methods Every group of acute lymphocytic leukemia(ALL),acute nonlymphocytic leukemia(ANLL) or non-leukemia group had 20 children who did not receive any treatment. Peripheral blood of every group and 20 other healthy children were aspirated .The levels of IL-15 in serum was analyzed by enzyme linked immunosorbent assay (ELISA).Results The levels of IL-15 in ALL group,ANLL group, non-leukemia group and healthy children were (34.37?2.8) ng/L, (29.61?3.2 )ng/L, (117.54?3.9) ng/L, (122.23?4.2) ng/L. Compared with the levels of the healthy group or the non-leukemia group, the difference of ALL or ANLL was signicant in statistics(q=3.95,4.03 Pa0.05).Conclusion Detection of serum IL-15 levels may have clinical significance in judging the anti-tumor immune condition in children with leukemia.

ObjectiveTo explore the new rehabilitation model of medication combined with education of cerebral palsy.MethodsThe cross-professionals were organized to assess and observe 126 children with cerebral palsy. Then, individual education plan (IEP) combined with medication, family, feeding was made and performed.ResultsAfter educational rehabilitation, the children with cerebral palsy got improvement in intellection, social adaptation, communion aspiration, thinking and etc. They became more cooperated in medical rehabilitation.ConclusionInterdisciplinary cooperation, IEP, participation of parents are the conditions for success of medical rehabilitation combined with education.
