In this study, we use pot experiment to evaluate the effect of plant growth regulator on plant morphology and biomass allocation of Salvia miltiorrhiza. Different concentrations of uniconazole were supplied to S. miltioohiza by means of foliar spray. Height, breadth and stem diameter were measured dynamically, the biomass of leaf, stem, flower and fruit, root biomass and biomass ratio were also examined at the harvest time. Owing to the treatment, plant morphology showed significant changes, the height had been greatly reduced and the breadth decreased largely. Meanwhile, the biomass allocation changed too. The biomass ratio of leaf and stem had been notably reduced while the biomass ratio of root had been increased remarkably. It appears that foliar application of uniconazole during vigorous growth period in S. miltioohiza has dramatic effect on dwarfing plant and improving resistant to lodging. This measure could also be applied to condensed cultivation of S. miltioohiza to increase production.

OBJECTIVETo demonstrate the chemical constituents of Alyxia sinensis.

METHODPhytochmical experiment was carried out, using column chromatograph technologies.

RESULTFive compounds have been isolated from the petroleum ether soluble part of the stems of A. sinensis. Their structures have been elucidated respectively as heptatriacontane(1), octatriacontane(2), 20-noatriacontannone(3), 20-nonatriacontanone(4), 20-tetraacontanoe(5), physcion(6), emodin(7), chrysophanol(8), coumarin(9), stigmasterol acetate(10), beta-sitosterol acetate(11), lupeol(12), betulin(13), stigmasterol(14), beta-sitosterol(15), ursolic acid(16), oleanolic acid(17).

CONCLUSIONAll these compounds are firstly been isolated from A. sinensis. And compound 5-9, 10, 11 are also been separated from Alyxiae genus for the first time.

In this paper the contents of rosmarinic acid, salvianolic acid B, crytotanshinone, tanshinone II(A) in samples of different original processed Salvia Miltiorrhizae Radix et Rhizoma were determined by HPLC. Different processing methods have varied influences on four active ingredients in Salvia Miltiorrhizae Radix et Rhizoma. Sun-drying reduced the content of crytotanshinone, tanshi-none II(A) and rosmarinic acid, integralsamples were better than those cut into segments. Oven dry method had great influence on water--soluble ingredients, high temperature (80-100 degrees C) could easily cause big loss of rosmarinic acid and salvianolic acid B. The role of traditional processing method "fahan: was complicated, the content of rosmarinic acid decreased, crytotanshinone and tanshinone II(A) increased, and salvianolic acid B showed no difference after "fahan". Drying in the shade and oven dry under low temperatrure (40-60 degrees C) were all effective to keep active ingredients of Salvia Miltiorrhizae Radix et Rhizoma, and, there was no difference between integral samples and samples cut into segments. Therefore, considering comprehensively the content of active ingredients in Salvia Miltiorrhizae Radix et Rhizoma, and processing costing etc., shade-drying or oven dry underlow temperature (40-60 degrees C) should be the most suitable original processing method.

Objective To summarize the condition of delayed elimination occurred on a patient with acute B lymphocytic leukemia after the forth time of high-dose methotrexate (MTX) chemotherapy and to analyze its reasons.Methods Reviewed the patient's relevant data during the four times of high-dose chemotherapy,including the therapeutic regimen,the results of therapeutic drug monitoring,and other relevant laboratory reports etc.What's more,consulted some related literature,further analyzed the reason of delayed elimination appeared on the patient after repeated chemotherapy of MTX in different views.Results The patient hadn't suffered the MTX relevant adverse reactions after the rescue drug therapy by calcium folinate etc.The blood concentration of MTX decreased to 0.10 μmol · L-1 after 216 hours of administration.It was suggested that the pH of the patient's urine was the possible reason influencing the elimination of MTX,but the foods,the cycles of chemotherapy and the disease stage also couldn't be excluded.Conclusion The blood drug concentration in the different cycles of MTX therapy for the patient were not same,and its specific mechanism needs an in-depth study.If the delayed elimination of MTX occurred,the rescue should be strengthened to ensure the safety and effectiveness of patients.

ABSTRACT:OBJECTIVE To observe the therapeutic effect of cervical spondylosis of vertebral artery type(CSA)with strong acupuncture stimulation to the second cervical vertebra transverse process.METHODS 100 patients with CSA were randomly divided into 3 groups.35 cases in the treatment group were treated with strong acupuncture stimulation to the second cervical vertebra transverse process for 10 minutes per day.30 cases in the control group were treated with routine acupuncture treat-ment for 30 minutes per day.35 cases in the hybrid group were first treated with strong acupuncture stimulation to the second cervical vertebra transverse process,which was followed by routine acupuncture treatment.RESULTS After 4 weeks of treat-ment,the total effective rate of the hybrid group was 94.1%,with the treatment group being 85.7% and the control group be-ing 73.3%.And notable statistical differences were detected among the three groups,with the hybrid group being superior to the treatment group and the treatment group being superior to the control group(P <0.05).Both hybrid group and treatment group were better than control group in onset time(P <0.05),with no evident difference being noticed between the hybrid group and treatment group(P >0.05).The treatment time of the hybrid group was shorten than that of the treatment group (P <0.05),together with the treatment group being shorten than the control group(P <0.05).Both hybrid group and treat-ment group were superior to control group in blood flow volume and average blood flow velocity(P <0.05),with no evident difference being noticed between the hybrid group and treatment group(P >0.05).CONCULSION The strong acupuncture stimulation to the second cervical vertebra transverse process has immediate effects in relieving symptoms of CSA and is able to be shorten the treatment course by improving blood supply of vertebral artery.

Objective::To analyze and identify the metabolites of major components of Shaoyao Gancaotang in urine and feces of normal and polycystic ovary syndrome (PCOS) rats, and to explore the effect of PCOS on the metabolism of Shaoyao Gancaotang. Method::Female SD rats were randomly divided into normal group and PCOS group. PCOS rat model was prepared by administration of letrozole solution for 21 days, and the estrous cycle of rats was observed. UHPLC-QTRAP-MS/MS technique and LightSight 2.3 software were used to analyze and identify the metabolites of major components of Shaoyao Gancaotang in urine and feces of normal and PCOS rats. The mobile phase was water-methanol for gradient elution, the flow rate was 0.3 mL·min^-1, electrospray ion source was employed under negative ion mode. Result::Phase Ⅰ and phase Ⅱ reactions mainly occurred in drug metabolism. A total of 27 metabolites were detected in urine of normal rats, and 34 metabolites were detected in urine of PCOS rats. A total of 29 metabolites were detected in feces of normal rats, and 27 metabolites were detected in feces of PCOS rats. Conclusion::The metabolites in the urine of PCOS rats are more diverse than those of normal rats, and the disease status of PCOS may affect the in vivo metabolic pathway of active ingredients in Shaoyao Gancaotang.
