The contents of lanata C in leaves of biennial Digitalis lanata were determined by means of radioimmunoassay.The results show that the contents of lanata C in leaves of Digitalis rapidly increased half a month before blossom and reached maximum between a week before and a week after blossom, and then decreased gradually. The contents of lanata C in a day reached maximum between .1 and 6 0'clock in the afternoon.This study will provide useful information for selecting an appropriate time to collect.

Objective To construct for the heredity linkage map and to study the functional gene research of Carthamus tinctorius,the factors affecting cDNA amplified fragment length polymorphism(cDNA-AFLP) of C.tinctorius were investigated with developing and optimizing the cDNA-AFLP reaction system.Methods Improved Trizol method was used to extract RNA from compounds in new petals specific to safflower.With the help of M-MLV RTase without RNase activity combined with replacement synthesis method,double-stranded cDNA was synthesized from total RNA;cDNA was digested by restriction enzyme MseI/EcoRI and ligated by two steps.Then the products were provided for pre-amplification and selected amplification of different concentration gradients.After tiny modifications of system concentration,finally PAGE electrophoresis and silver-staining were performed.Results High purity and integrated total RNA for later cDNA synthesis were obtained and high quality cDNA was synthesized with the help of M-MLV RTase without RNase activity combined with replacement synthesis method.The cDNA-AFLP reaction system in C.tinctorius was as follows: 250 ng integrity cDNA was digested thoroughly at 37 ℃ for 6 h,and ligated 12 h at 16 ℃.Furthermore,the sample dilution multiplication was 10 fold for pre-amplification and 150 fold for selected amplification under the proper system concentration.According to the above reaction system,the polymorphous strips with high resolution power in PAGE electrophoresis were clear and stable.Conclusion The cDNA-AFLP reaction system established and optimized in this experiment is suitable for the functional gene analysis of C.tinctorius.

Objective: To study the proper medium for tissue culture of the explants from Hypericum perforatum . Methods: The root, stem with node and leaf of the Hypericum perforatum seedling were used as explants, and cultured in basic Murashige and Skoog (MS) medium supplemented with different kinds and different concentrations of hormones. The callus, buds and roots were induced. The cultivation of the tube seedling were carried out. Results: Different hormones and explants had different effects on the induction of callus and the formation of buds. 2,4 D could promote the formation of the callus of Hypericum perforatum . Among cytokinins, 6 BA had great effect on the formation of buds, but the effects of KT and ZT were insignificant. The combination of NAA 1 mg/L and 6 BA 0.2 mg/L was found most effective in promoting the rooting of Hypericum perforatum . Conclusion: The results indicate that the callus is easy to be induced when MS medium supplemented with 2,4 D. The root of explants is most suitable for the rosette bud rapid induction.

Objective:To study the high-performance liquid chromatographic(HPLC) fingerprints of different germplasms of Flos Carthami. Methods: HPLC was applied in chromatographic separation of 36 different germplasms of Flos Carthami collected from 11 provinces of China.The chromatography condition was: Agilent Zorbax C_(18) column(4.6 mm?250 mm,5 mm);mobile phase: CAN,0.5% H_3PO_4(from 1090 to 8020);running time: 60 min;flow speed: 1.0 ml/min;detection wavelength: 265 nm;and temperature: 20℃.The data were processed by Chromatographic Fingerprint Station designed by Department of Pharmaceutical Analysis,School of Pharmacy,Second Military Medical University.Different germplasms of Flos Carthami were subjected to cluster analysis and their similarity was also evaluated.Results: The different germplasms of Flos Carthami in this study were grouped into 2 chemical types.Samples from northwest of China were of high similarity;samples from the middle China were of high similarity to those from South China.The similarity of some germplasms of Flos Carthami was significantly different.Conclusion: The chemical components of different germplasms of Flos Carthami are obviously different from each other;selection of germplasm is very important in quality control of Flos Carthami.

Objective: To establish the culture system of hairy root of Isatis indigotica and to induce the regeneration plant of hairy root. Methods: Hairy root of Isatis indigotica was obtained from infected cotyledon explants after infection with Agrobacterium rhizogenes strains A4, R1601 and ATCC15834. The better lines were selected. The growth curve was surveyed and extrinsic factors affecting the growth of hairy roots were investigated. The regeneration plant was induced on MS media with different hormones. The transformation of Ri T DNA was examined through high voltage paper electrophoresis. Results: The hairy root was originally obtained from Isatis indigotica . The regeneration plant was induced on MS media with BA. The result of high voltage paper electrophoresis confirmed the transformation of T DNA from Ri plasmid to the hairy root and regeneration plant. Conclusion: The acquisition of hairy root of Isatis indigotica and regeneration plant of it lay a foundation for the production of active component and introduction of foreign gene. [

Objective To investigate the efficacy of aripiprazole addition therapy on adiponectin and leptin in schizophrenia patients with olanzapine-induced weight gain. Methods Schizophrenia patients with clinically significant weight gain induced by olanzapine were randomly divided into two groups:treated with olanzapine+aripiprazole (5 mg/d, n=48) or olanzapine+placebo (n=46). The level of FBS, TG, TC, adiponectin, leptin, the body index (BMI) and the insu?lin resistance index (HOMA-IR) were measured before and 4, 8 and 12 weeks after treatment. Results Adiponectin in?creased and leptin as well as HOMA-IR decreased in olanzapine+aripiprazole group after 4, 8 and 12 weeks treatment (P<0.05). However, FBS, TG and TC decreased and BMI increased only after 8 and 12 weeks treatment(P<0.05). In olanzapine+placebo group, the dadiponectin decreased and leptin, HOMA-IR as well as BMI increased after 8 and 12 weeks treatment(P<0.05). In olanzapine + aripiprazole group the adiponectin, leptin and HOMA-IR of 4, 8 and 12 weeks and BMI of 8 and 12 weeks were different from olanzapine + placebo group(P<0.05). Conclusions In schizo?phrenia patients with olanzapine-induced weight gain, aripiprazole addition therapy can ameliorate the HOMA-IR and BMI probably through the regulation of adiponectin and leptin.

OBJECTIVE: To observe clinical efficacy of Bifid tripie viable enteric-coated capsules in the treatment of children diarrhea after pneumonia. METHODS: 360 cases of children pneumonia were randomly divided into two groups. Treatment group were treated with antibiotics and Bifid triple viable enteric-coated capsules in duration of hospital stay(n=180). Control group were treated with antibiotics only (n=180). The incidence and severity of diarrhea in two groups were observed at the 3rd, 5th, 7th of therapy. RESULTS: The incidence of diarrhea at the 3rd, 5th, 7th of therapy in treatment group were 10.00%,16.67% and 13.33%, in control group 36.67%, 43.33% and 50.00%, with statistically significance(P
